Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) The accompanying consolidated financial statements include the accounts of Entergy Corporation and its subsidiaries. As required by GAAP in the United States of America, all intercompany transactions have been eliminated in the consolidated financial statements. Entergy’s Registrant Subsidiaries (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) also include their separate financial statements in this Form 10-K. Historical share and share-based data presented herein, including share-based compensation, has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Certain previously reported amounts in the financial statements have been reclassified to conform to current classification, with no effect on results of operations, financial positions, or cash flows. The Registrant Subsidiaries and many other Entergy subsidiaries also maintain accounts in accordance with FERC and other regulatory guidelines. Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used. Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs. Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements.

Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements. Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line. Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets. Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment. Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders. Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements. Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents. Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts. Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies. Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds. Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership. Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value. Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets. Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024. Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority. New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these ca

Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) The accompanying consolidated financial statements include the accounts of Entergy Corporation and its subsidiaries. As required by GAAP in the United States of America, all intercompany transactions have been eliminated in the consolidated financial statements. Entergy’s Registrant Subsidiaries (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) also include their separate financial statements in this Form 10-K. Historical share and share-based data presented herein, including share-based compensation, has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Certain previously reported amounts in the financial statements have been reclassified to conform to current classification, with no effect on results of operations, financial positions, or cash flows. The Registrant Subsidiaries and many other Entergy subsidiaries also maintain accounts in accordance with FERC and other regulatory guidelines. Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used. Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs. Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for the Registrant Subsidiaries by functional category, as of December 31, 2024 and 2023, is shown below: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Millions) Production Nuclear $1,887 $4,121 $— $— $— $2,016 Other 1,721 3,532 980 374 1,154 — Transmission 2,267 4,339 1,567 155 2,054 30 Distribution 3,615 4,973 2,418 761 2,554 — Other 606 1,175 385 384 318 44 Construction work in progress 320 762 487 20 1,513 85 Nuclear fuel 258 288 — — — 220 Property, plant, and equipment - net (a) $10,674 $19,190 $5,837 $1,694 $7,593 $2,395 (a) Includes $164 million of natural gas property, plant, and equipment and accumulated depreciation and $1 million of construction work in progress for Entergy Louisiana and $239 million of natural gas property, plant, and equipment and accumulated depreciation and $2 million of construction work in progress for Entergy New Orleans classified as held for sale in “Non-current assets held for sale” on their respective consolidated balance sheet as of December 31, 2024.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023. Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements. Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line. Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets. Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment. Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders. Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements. Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents. Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts. Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies. Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds. Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership. Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value. Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets. Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024. Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority. New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these ca

Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) The accompanying consolidated financial statements include the accounts of Entergy Corporation and its subsidiaries. As required by GAAP in the United States of America, all intercompany transactions have been eliminated in the consolidated financial statements. Entergy’s Registrant Subsidiaries (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) also include their separate financial statements in this Form 10-K. Historical share and share-based data presented herein, including share-based compensation, has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Certain previously reported amounts in the financial statements have been reclassified to conform to current classification, with no effect on results of operations, financial positions, or cash flows. The Registrant Subsidiaries and many other Entergy subsidiaries also maintain accounts in accordance with FERC and other regulatory guidelines. Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used. Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs. Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for the Registrant Subsidiaries by functional category, as of December 31, 2024 and 2023, is shown below: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Millions) Production Nuclear $1,887 $4,121 $— $— $— $2,016 Other 1,721 3,532 980 374 1,154 — Transmission 2,267 4,339 1,567 155 2,054 30 Distribution 3,615 4,973 2,418 761 2,554 — Other 606 1,175 385 384 318 44 Construction work in progress 320 762 487 20 1,513 85 Nuclear fuel 258 288 — — — 220 Property, plant, and equipment - net (a) $10,674 $19,190 $5,837 $1,694 $7,593 $2,395 (a) Includes $164 million of natural gas property, plant, and equipment and accumulated depreciation and $1 million of construction work in progress for Entergy Louisiana and $239 million of natural gas property, plant, and equipment and accumulated depreciation and $2 million of construction work in progress for Entergy New Orleans classified as held for sale in “Non-current assets held for sale” on their respective consolidated balance sheet as of December 31, 2024.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023. Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements. Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line. Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets. Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment. Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders. Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements. Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents. Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts. Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies. Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds. Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership. Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value. Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets. Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024. Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority. New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these ca

Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) The accompanying consolidated financial statements include the accounts of Entergy Corporation and its subsidiaries. As required by GAAP in the United States of America, all intercompany transactions have been eliminated in the consolidated financial statements. Entergy’s Registrant Subsidiaries (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) also include their separate financial statements in this Form 10-K. Historical share and share-based data presented herein, including share-based compensation, has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Certain previously reported amounts in the financial statements have been reclassified to conform to current classification, with no effect on results of operations, financial positions, or cash flows. The Registrant Subsidiaries and many other Entergy subsidiaries also maintain accounts in accordance with FERC and other regulatory guidelines. Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used. Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs. Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for the Registrant Subsidiaries by functional category, as of December 31, 2024 and 2023, is shown below: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Millions) Production Nuclear $1,887 $4,121 $— $— $— $2,016 Other 1,721 3,532 980 374 1,154 — Transmission 2,267 4,339 1,567 155 2,054 30 Distribution 3,615 4,973 2,418 761 2,554 — Other 606 1,175 385 384 318 44 Construction work in progress 320 762 487 20 1,513 85 Nuclear fuel 258 288 — — — 220 Property, plant, and equipment - net (a) $10,674 $19,190 $5,837 $1,694 $7,593 $2,395 (a) Includes $164 million of natural gas property, plant, and equipment and accumulated depreciation and $1 million of construction work in progress for Entergy Louisiana and $239 million of natural gas property, plant, and equipment and accumulated depreciation and $2 million of construction work in progress for Entergy New Orleans classified as held for sale in “Non-current assets held for sale” on their respective consolidated balance sheet as of December 31, 2024.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023. Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements. Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line. Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets. Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment. Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders. Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements. Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents. Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts. Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies. Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds. Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership. Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value. Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets. Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024. Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority. New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these ca

Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) The accompanying consolidated financial statements include the accounts of Entergy Corporation and its subsidiaries. As required by GAAP in the United States of America, all intercompany transactions have been eliminated in the consolidated financial statements. Entergy’s Registrant Subsidiaries (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) also include their separate financial statements in this Form 10-K. Historical share and share-based data presented herein, including share-based compensation, has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Certain previously reported amounts in the financial statements have been reclassified to conform to current classification, with no effect on results of operations, financial positions, or cash flows. The Registrant Subsidiaries and many other Entergy subsidiaries also maintain accounts in accordance with FERC and other regulatory guidelines. Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used. Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs. Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023. Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements. Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line. Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets. Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment. Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders. Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements. Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents. Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts. Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies. Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds. Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership. Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value. Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets. Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024. Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority. New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these ca

Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) The accompanying consolidated financial statements include the accounts of Entergy Corporation and its subsidiaries. As required by GAAP in the United States of America, all intercompany transactions have been eliminated in the consolidated financial statements. Entergy’s Registrant Subsidiaries (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) also include their separate financial statements in this Form 10-K. Historical share and share-based data presented herein, including share-based compensation, has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Certain previously reported amounts in the financial statements have been reclassified to conform to current classification, with no effect on results of operations, financial positions, or cash flows. The Registrant Subsidiaries and many other Entergy subsidiaries also maintain accounts in accordance with FERC and other regulatory guidelines. Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used. Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs. Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023.

Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements. Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line. Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets. Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment. Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders. Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements. Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents. Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts. Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies. Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds. Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership. Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value. Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets. Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024. Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority. New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these ca

Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) The accompanying consolidated financial statements include the accounts of Entergy Corporation and its subsidiaries. As required by GAAP in the United States of America, all intercompany transactions have been eliminated in the consolidated financial statements. Entergy’s Registrant Subsidiaries (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) also include their separate financial statements in this Form 10-K. Historical share and share-based data presented herein, including share-based compensation, has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Certain previously reported amounts in the financial statements have been reclassified to conform to current classification, with no effect on results of operations, financial positions, or cash flows. The Registrant Subsidiaries and many other Entergy subsidiaries also maintain accounts in accordance with FERC and other regulatory guidelines. Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used. Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs. Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method.

Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements. Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line. Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets. Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment. Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders. Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements. Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents. Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts. Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies. Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds. Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership. Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value. Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets. Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024. Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority. New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these ca

Regulatory activity regarding the Tax Cuts and Jobs Act See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act), including its effects on Entergy’s and the Registrant Subsidiaries’ regulatory asset/liability for income taxes. Entergy Louisiana In an electric formula rate plan settlement approved by the LPSC in April 2018, the parties agreed that Entergy Louisiana would return to customers one-half of its eligible unprotected excess deferred income taxes from May 2018 through December 2018 and return to customers the other half from January 2019 through August 2022. In addition, the settlement provided that in order to flow back to customers certain other tax benefits created by the Tax Act, Entergy Louisiana established a regulatory liability effective January 1, 2018 in the amount of $9.1 million per month to reflect these tax benefits already included in retail rates until new base rates under the formula rate plan were established in September 2018, and this regulatory liability was returned to customers over the September 2018 through August 2019 formula rate plan rate-effective period. The LPSC staff and intervenors in the settlement reserved the right to obtain data from Entergy Louisiana to confirm the determination of excess accumulated deferred income taxes resulting from the Tax Act and the analysis thereof as part of the formula rate plan review proceeding for the 2017 test year filing. As discussed below in “ Retail Rate Proceedings - Filings with the LPSC (Entergy Louisiana) - Retail Rates - Electric - Formula Rate Plan Global Settlement”, a global settlement resolving the outstanding issues related to the 2017 formula rate plan filing was reached in October 2023 and approved by the LPSC in November 2023. System Energy In a filing made with the FERC in March 2018, System Energy proposed revisions to the Unit Power Sales Agreement to reflect the effects of the Tax Act. In the filing System Energy proposed to return identified quantities of unprotected excess accumulated deferred income taxes to its customers by the end of 2018. In May 2018 the FERC accepted System Energy’s proposed tax revisions with an effective date of June 1, 2018, subject to refund and the outcome of settlement and hearing procedures. Settlement discussions were terminated in April 2019, and a hearing was held in March 2020. In December 2022 the FERC issued an order requiring System Energy to compute the amount of excess accumulated deferred income taxes associated with a previously uncertain decommissioning tax position with consideration for the resolution of the tax position by the IRS. In February 2023, System Energy submitted its compliance filing. This matter was ultimately settled as a result of System Energy’s settlements with the MPSC, the APSC, the City Council, and the LPSC. See “ Complaints Against System Energy ” below for further discussion of the System Energy settlements with the MPSC, the APSC, the City Council, and the LPSC. Fuel and purchased power cost recovery The Utility operating companies are allowed to recover fuel and purchased power costs through fuel mechanisms included in electric and gas rates that are recorded as fuel cost recovery revenues. The difference between revenues collected and the current fuel and purchased power costs is generally recorded as “Deferred fuel costs” on the Utility operating companies’ financial statements. The table below shows the amount of deferred fuel costs as of December 31, 2024 and 2023 that each Utility operating company expects to recover (or return to customers) through fuel mechanisms, subject to subsequent regulatory review. 2024 2023 (In Millions) Entergy Arkansas ($45.2) ($88.3) Entergy Louisiana (a) (b) $163.4 $192.9 Entergy Mississippi ($126.3) ($130.6) Entergy New Orleans (a) (b) $8.0 $10.2 Entergy Texas ($59.3) $139.0 (a) Includes $168.1 million in both years for Entergy Louisiana and $4.1 million in both years for Entergy New Orleans of fuel, purchased power, and capacity costs, which do not currently earn a return on investment and whose recovery periods are indeterminate but are expected to be recovered over a period greater than twelve months. (b) Includes $0.7 million at Entergy Louisiana and $4.9 million at Entergy New Orleans as of December 31, 2024 of deferred fuel assets related to the respective natural gas distribution businesses classified as held for sale and included within “Current assets held for sale” on the respective consolidated balance sheets. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Entergy Arkansas Energy Cost Recovery Rider Entergy Arkansas’s retail rates include an energy cost recovery rider to recover fuel and purchased energy costs in monthly customer bills. The rider utilizes the prior calendar-year energy costs and projected energy sales for the twelve-month period commencing on April 1 of each year to develop an energy cost rate, which is redetermined annually and includes a true-up adjustment reflecting the over- or under-recovery, including carrying charges, of the energy costs for the prior calendar year. The energy cost recovery rider tariff also allows an interim rate request depending upon the level of over- or under-recovery of fuel and purchased energy costs. In January 2014, Entergy Arkansas filed a motion with the APSC relating to its upcoming energy cost rate redetermination filing that was made in March 2014. In that motion, Entergy Arkansas requested that the APSC authorize Entergy Arkansas to exclude from the redetermination of its 2014 energy cost rate $65.9 million of incremental fuel and replacement energy costs incurred in 2013 as a result of the ANO stator incident. Entergy Arkansas requested that the APSC authorize Entergy Arkansas to retain that amount in its deferred fuel balance, with recovery to be reviewed in a later period after more information was available regarding various claims associated with the ANO stator incident. In February 2014 the APSC approved Entergy Arkansas’s request to retain that amount in its deferred fuel balance. In July 2017, Entergy Arkansas filed for a change in rates pursuant to its formula rate plan rider. In that proceeding, the APSC approved a settlement agreement agreed upon by the parties, including a provision that requires Entergy Arkansas to initiate a regulatory proceeding for the purpose of recovering funds currently withheld from rates and related to the stator incident, including the $65.9 million of deferred fuel and purchased energy costs and costs related to the incremental oversight previously noted, subject to certain timelines and conditions set forth in the settlement agreement. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the incremental fuel and purchased energy expense, among other identified costs, resulting from the ANO stator incident. As a result, in third quarter 2023, Entergy Arkansas recorded a write-off of its regulatory asset for deferred fuel of $68.9 million, which includes interest, related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. See the “ ANO Damage, Outage, and NRC Reviews ” section in Note 8 to the financial statements for further discussion of the ANO stator incident and the approved motion to forgo recovery . In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh. The APSC staff filed testimony in March 2017 recommending that the redetermined rate be implemented with the first billing cycle of April 2017 under the normal operation of the tariff. Accordingly, the redetermined rate went into effect on March 31, 2017 pursuant to the tariff. In July 2017 the Arkansas Attorney General requested additional information to support certain of the costs included in Entergy Arkansas’s 2017 energy cost rate redetermination. In March 2018, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01547 per kWh to $0.01882 per kWh. The Arkansas Attorney General filed a response to Entergy Arkansas’s annual redetermination filing requesting that the APSC suspend the proposed tariff to investigate the amount of the redetermination or, alternatively, to allow recovery subject to refund. Among the reasons the Attorney General cited for suspension were questions pertaining to how Entergy Arkansas forecasted sales and potential implications of the Tax Cuts and Jobs Act. Entergy Arkansas replied to the Attorney General’s filing and stated that, to the extent there are questions pertaining to its load forecasting or the operation of the energy cost recovery rider, those issues exceed the scope of the instant rate redetermination. Entergy Arkansas also stated that potential effects of the Tax Cuts and Jobs Act are appropriately considered in the APSC’s separate proceeding regarding potential implications of the tax law. The APSC general staff filed a reply to the Attorney General’s filing and agreed that Entergy Arkansas’s filing complied with the terms of the energy cost recovery rider. The redetermined rate became effective with the first billing cycle of April 2018. Subsequently in April 2018 the APSC issued an order declining to suspend Entergy Arkansas’s energy cost recovery rider rate and declining to require further investigation at that time of the issues suggested by the Attorney General in the proceeding. Following a period of discovery, the Attorney General filed a supplemental response in October 2018 raising new issues with Entergy Arkansas’s March 2018 rate redetermination and asserting that $45.7 million of the increase should be collected subject to refund pending further investigation. Entergy Arkansas filed to dismiss the Attorney General’s supplemental response, the APSC general staff filed a motion to strike the Attorney General’s filing, and the Attorney General filed a supplemental response disputing Entergy Arkansas and the APSC staff’s filing. Applicable APSC rules and processes authorize its general staff to initiate periodic audits of Entergy Arkansas’s energy cost recovery rider. In late-2018 the APSC general staff notified Entergy Arkansas it initiated an audit of the 2017 fuel costs. The time in which the audit will be complete is uncertain at this time. In March 2022, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00959 per kWh to $0.01785 per kWh. The primary reason for the rate increase was a large under-recovered balance as a result of higher natural gas prices in 2021, particularly in the fourth quarter 2021. At the request of the APSC general staff, Entergy Arkansas deferred its request for recovery of $32 million from the under-recovery related to the February 2021 winter storms until the 2023 energy cost rate redetermination, unless a request for an interim adjustment to the energy cost recovery rider is necessary. This resulted in a redetermined rate of $0.016390 per kWh, which became effective with the first billing cycle in April 2022 through the normal operation of the tariff. In February 2023 the APSC issued orders initiating proceedings with the utilities under its jurisdiction to address the prudence of costs incurred and appropriate cost allocation of the February 2021 winter storms. With respect to any prudence review of Entergy Arkansas fuel costs, as part of the APSC’s draft report issued in its February 2021 winter storms investigation docket, the APSC included findings that the load shedding plans of the investor-owned utilities and some cooperatives were appropriate and comprehensive, and, further, that Entergy Arkansas’s emergency plan was comprehensive and had a multilayered approach supported by a system-wide response plan, which is considered an industry standard. In September 2023 the APSC issued an order in Entergy Arkansas's company-specific proceeding and found that Entergy Arkansas’s practices during the winter storms were prudent. In March 2023, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01639 per kWh to $0.01883 per kWh. The primary reason for the rate increase is a large under-recovered balance as a result of higher natural gas prices in 2022 and a $32 million deferral related to the February 2021 winter storms consistent with the APSC general staff’s request in 2022. The under-recovered balance included in the filing was partially offset by the proceeds of the $41.7 million refund that System Energy made to Entergy Arkansas in January 2023 related to the sale-leaseback renewal costs and depreciation litigation as calculated in System Energy’s January 2023 compliance report filed with the FERC. See “ Complaints Against System Energy - Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue ” below for discussion of the compliance report filed by System Energy with the FERC in January 2023. The redetermined rate of $0.01883 per kWh became effective with the first billing cycle in April 2023 through the normal operation of the tariff. In March 2024, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected a decrease in the rate from $0.01883 per kWh to $0.00882 per kWh. Due to a change in law in the State of Arkansas, the annual redetermination included $9 million, recorded as a credit to fuel expense in first quarter 2024, for recovery attributed to net metering costs in 2023. The primary reason for the rate decrease is a large over-recovered balance as a result of lower natural gas prices in 2023. To mitigate the effect of projected increases in natural gas prices in 2024, Entergy Arkansas adjusted the over-recovered balance included in the March 2024 annual redetermination filing by $43.7 million. This adjustment is expected to reduce the rate change that will be reflected in the 2025 energy cost rate redetermination. The redetermined rate of $0.00882 per kWh became effective with the first billing cycle in April 2024 through the normal operation of the tariff. Entergy Louisiana Entergy Louisiana recovers electric fuel and purchased power costs for the billing month based upon the level of such costs incurred two months prior to the billing month. Entergy Louisiana’s purchased gas adjustments include estimates for the billing month adjusted by a surcharge or credit that arises from an annual reconciliation of fuel costs incurred with fuel cost revenues billed to customers, including carrying charges. To mitigate high electric bills, primarily driven by high summer usage and elevated gas prices, Entergy Louisiana deferred approximately $225 million of fuel expense incurred in April, May, June, July, August, and September 2022 (as reflected on June, July, August, September, October, and November 2022 bills). These deferrals were included in the over/under calculation of the fuel adjustment clause, which is intended to recover the full amount of the costs included on a rolling twelve-month basis. In March 2020 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2016 through 2019. The LPSC staff issued its audit report in September 2021, and although certain internal record keeping recommendations were made, the LPSC staff did not recommend any disallowances. The next step is for the LPSC to review the report, but there is not a deadline for the review. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. Discovery is ongoing, and no audit report has been filed. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2020 through 2022. Discovery is ongoing, and no audit report has been filed. Entergy Mississippi Entergy Mississippi’s rate schedules includ

Regulatory activity regarding the Tax Cuts and Jobs Act See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act), including its effects on Entergy’s and the Registrant Subsidiaries’ regulatory asset/liability for income taxes. Entergy Louisiana In an electric formula rate plan settlement approved by the LPSC in April 2018, the parties agreed that Entergy Louisiana would return to customers one-half of its eligible unprotected excess deferred income taxes from May 2018 through December 2018 and return to customers the other half from January 2019 through August 2022. In addition, the settlement provided that in order to flow back to customers certain other tax benefits created by the Tax Act, Entergy Louisiana established a regulatory liability effective January 1, 2018 in the amount of $9.1 million per month to reflect these tax benefits already included in retail rates until new base rates under the formula rate plan were established in September 2018, and this regulatory liability was returned to customers over the September 2018 through August 2019 formula rate plan rate-effective period. The LPSC staff and intervenors in the settlement reserved the right to obtain data from Entergy Louisiana to confirm the determination of excess accumulated deferred income taxes resulting from the Tax Act and the analysis thereof as part of the formula rate plan review proceeding for the 2017 test year filing. As discussed below in “ Retail Rate Proceedings - Filings with the LPSC (Entergy Louisiana) - Retail Rates - Electric - Formula Rate Plan Global Settlement”, a global settlement resolving the outstanding issues related to the 2017 formula rate plan filing was reached in October 2023 and approved by the LPSC in November 2023. System Energy In a filing made with the FERC in March 2018, System Energy proposed revisions to the Unit Power Sales Agreement to reflect the effects of the Tax Act. In the filing System Energy proposed to return identified quantities of unprotected excess accumulated deferred income taxes to its customers by the end of 2018. In May 2018 the FERC accepted System Energy’s proposed tax revisions with an effective date of June 1, 2018, subject to refund and the outcome of settlement and hearing procedures. Settlement discussions were terminated in April 2019, and a hearing was held in March 2020. In December 2022 the FERC issued an order requiring System Energy to compute the amount of excess accumulated deferred income taxes associated with a previously uncertain decommissioning tax position with consideration for the resolution of the tax position by the IRS. In February 2023, System Energy submitted its compliance filing. This matter was ultimately settled as a result of System Energy’s settlements with the MPSC, the APSC, the City Council, and the LPSC. See “ Complaints Against System Energy ” below for further discussion of the System Energy settlements with the MPSC, the APSC, the City Council, and the LPSC. Fuel and purchased power cost recovery The Utility operating companies are allowed to recover fuel and purchased power costs through fuel mechanisms included in electric and gas rates that are recorded as fuel cost recovery revenues. The difference between revenues collected and the current fuel and purchased power costs is generally recorded as “Deferred fuel costs” on the Utility operating companies’ financial statements. The table below shows the amount of deferred fuel costs as of December 31, 2024 and 2023 that each Utility operating company expects to recover (or return to customers) through fuel mechanisms, subject to subsequent regulatory review. 2024 2023 (In Millions) Entergy Arkansas ($45.2) ($88.3) Entergy Louisiana (a) (b) $163.4 $192.9 Entergy Mississippi ($126.3) ($130.6) Entergy New Orleans (a) (b) $8.0 $10.2 Entergy Texas ($59.3) $139.0 (a) Includes $168.1 million in both years for Entergy Louisiana and $4.1 million in both years for Entergy New Orleans of fuel, purchased power, and capacity costs, which do not currently earn a return on investment and whose recovery periods are indeterminate but are expected to be recovered over a period greater than twelve months. (b) Includes $0.7 million at Entergy Louisiana and $4.9 million at Entergy New Orleans as of December 31, 2024 of deferred fuel assets related to the respective natural gas distribution businesses classified as held for sale and included within “Current assets held for sale” on the respective consolidated balance sheets. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Entergy Arkansas Energy Cost Recovery Rider Entergy Arkansas’s retail rates include an energy cost recovery rider to recover fuel and purchased energy costs in monthly customer bills. The rider utilizes the prior calendar-year energy costs and projected energy sales for the twelve-month period commencing on April 1 of each year to develop an energy cost rate, which is redetermined annually and includes a true-up adjustment reflecting the over- or under-recovery, including carrying charges, of the energy costs for the prior calendar year. The energy cost recovery rider tariff also allows an interim rate request depending upon the level of over- or under-recovery of fuel and purchased energy costs. In January 2014, Entergy Arkansas filed a motion with the APSC relating to its upcoming energy cost rate redetermination filing that was made in March 2014. In that motion, Entergy Arkansas requested that the APSC authorize Entergy Arkansas to exclude from the redetermination of its 2014 energy cost rate $65.9 million of incremental fuel and replacement energy costs incurred in 2013 as a result of the ANO stator incident. Entergy Arkansas requested that the APSC authorize Entergy Arkansas to retain that amount in its deferred fuel balance, with recovery to be reviewed in a later period after more information was available regarding various claims associated with the ANO stator incident. In February 2014 the APSC approved Entergy Arkansas’s request to retain that amount in its deferred fuel balance. In July 2017, Entergy Arkansas filed for a change in rates pursuant to its formula rate plan rider. In that proceeding, the APSC approved a settlement agreement agreed upon by the parties, including a provision that requires Entergy Arkansas to initiate a regulatory proceeding for the purpose of recovering funds currently withheld from rates and related to the stator incident, including the $65.9 million of deferred fuel and purchased energy costs and costs related to the incremental oversight previously noted, subject to certain timelines and conditions set forth in the settlement agreement. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the incremental fuel and purchased energy expense, among other identified costs, resulting from the ANO stator incident. As a result, in third quarter 2023, Entergy Arkansas recorded a write-off of its regulatory asset for deferred fuel of $68.9 million, which includes interest, related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. See the “ ANO Damage, Outage, and NRC Reviews ” section in Note 8 to the financial statements for further discussion of the ANO stator incident and the approved motion to forgo recovery . In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh. The APSC staff filed testimony in March 2017 recommending that the redetermined rate be implemented with the first billing cycle of April 2017 under the normal operation of the tariff. Accordingly, the redetermined rate went into effect on March 31, 2017 pursuant to the tariff. In July 2017 the Arkansas Attorney General requested additional information to support certain of the costs included in Entergy Arkansas’s 2017 energy cost rate redetermination. In March 2018, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01547 per kWh to $0.01882 per kWh. The Arkansas Attorney General filed a response to Entergy Arkansas’s annual redetermination filing requesting that the APSC suspend the proposed tariff to investigate the amount of the redetermination or, alternatively, to allow recovery subject to refund. Among the reasons the Attorney General cited for suspension were questions pertaining to how Entergy Arkansas forecasted sales and potential implications of the Tax Cuts and Jobs Act. Entergy Arkansas replied to the Attorney General’s filing and stated that, to the extent there are questions pertaining to its load forecasting or the operation of the energy cost recovery rider, those issues exceed the scope of the instant rate redetermination. Entergy Arkansas also stated that potential effects of the Tax Cuts and Jobs Act are appropriately considered in the APSC’s separate proceeding regarding potential implications of the tax law. The APSC general staff filed a reply to the Attorney General’s filing and agreed that Entergy Arkansas’s filing complied with the terms of the energy cost recovery rider. The redetermined rate became effective with the first billing cycle of April 2018. Subsequently in April 2018 the APSC issued an order declining to suspend Entergy Arkansas’s energy cost recovery rider rate and declining to require further investigation at that time of the issues suggested by the Attorney General in the proceeding. Following a period of discovery, the Attorney General filed a supplemental response in October 2018 raising new issues with Entergy Arkansas’s March 2018 rate redetermination and asserting that $45.7 million of the increase should be collected subject to refund pending further investigation. Entergy Arkansas filed to dismiss the Attorney General’s supplemental response, the APSC general staff filed a motion to strike the Attorney General’s filing, and the Attorney General filed a supplemental response disputing Entergy Arkansas and the APSC staff’s filing. Applicable APSC rules and processes authorize its general staff to initiate periodic audits of Entergy Arkansas’s energy cost recovery rider. In late-2018 the APSC general staff notified Entergy Arkansas it initiated an audit of the 2017 fuel costs. The time in which the audit will be complete is uncertain at this time. In March 2022, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00959 per kWh to $0.01785 per kWh. The primary reason for the rate increase was a large under-recovered balance as a result of higher natural gas prices in 2021, particularly in the fourth quarter 2021. At the request of the APSC general staff, Entergy Arkansas deferred its request for recovery of $32 million from the under-recovery related to the February 2021 winter storms until the 2023 energy cost rate redetermination, unless a request for an interim adjustment to the energy cost recovery rider is necessary. This resulted in a redetermined rate of $0.016390 per kWh, which became effective with the first billing cycle in April 2022 through the normal operation of the tariff. In February 2023 the APSC issued orders initiating proceedings with the utilities under its jurisdiction to address the prudence of costs incurred and appropriate cost allocation of the February 2021 winter storms. With respect to any prudence review of Entergy Arkansas fuel costs, as part of the APSC’s draft report issued in its February 2021 winter storms investigation docket, the APSC included findings that the load shedding plans of the investor-owned utilities and some cooperatives were appropriate and comprehensive, and, further, that Entergy Arkansas’s emergency plan was comprehensive and had a multilayered approach supported by a system-wide response plan, which is considered an industry standard. In September 2023 the APSC issued an order in Entergy Arkansas's company-specific proceeding and found that Entergy Arkansas’s practices during the winter storms were prudent. In March 2023, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01639 per kWh to $0.01883 per kWh. The primary reason for the rate increase is a large under-recovered balance as a result of higher natural gas prices in 2022 and a $32 million deferral related to the February 2021 winter storms consistent with the APSC general staff’s request in 2022. The under-recovered balance included in the filing was partially offset by the proceeds of the $41.7 million refund that System Energy made to Entergy Arkansas in January 2023 related to the sale-leaseback renewal costs and depreciation litigation as calculated in System Energy’s January 2023 compliance report filed with the FERC. See “ Complaints Against System Energy - Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue ” below for discussion of the compliance report filed by System Energy with the FERC in January 2023. The redetermined rate of $0.01883 per kWh became effective with the first billing cycle in April 2023 through the normal operation of the tariff. In March 2024, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected a decrease in the rate from $0.01883 per kWh to $0.00882 per kWh. Due to a change in law in the State of Arkansas, the annual redetermination included $9 million, recorded as a credit to fuel expense in first quarter 2024, for recovery attributed to net metering costs in 2023. The primary reason for the rate decrease is a large over-recovered balance as a result of lower natural gas prices in 2023. To mitigate the effect of projected increases in natural gas prices in 2024, Entergy Arkansas adjusted the over-recovered balance included in the March 2024 annual redetermination filing by $43.7 million. This adjustment is expected to reduce the rate change that will be reflected in the 2025 energy cost rate redetermination. The redetermined rate of $0.00882 per kWh became effective with the first billing cycle in April 2024 through the normal operation of the tariff. Entergy Louisiana Entergy Louisiana recovers electric fuel and purchased power costs for the billing month based upon the level of such costs incurred two months prior to the billing month. Entergy Louisiana’s purchased gas adjustments include estimates for the billing month adjusted by a surcharge or credit that arises from an annual reconciliation of fuel costs incurred with fuel cost revenues billed to customers, including carrying charges. To mitigate high electric bills, primarily driven by high summer usage and elevated gas prices, Entergy Louisiana deferred approximately $225 million of fuel expense incurred in April, May, June, July, August, and September 2022 (as reflected on June, July, August, September, October, and November 2022 bills). These deferrals were included in the over/under calculation of the fuel adjustment clause, which is intended to recover the full amount of the costs included on a rolling twelve-month basis. In March 2020 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2016 through 2019. The LPSC staff issued its audit report in September 2021, and although certain internal record keeping recommendations were made, the LPSC staff did not recommend any disallowances. The next step is for the LPSC to review the report, but there is not a deadline for the review. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. Discovery is ongoing, and no audit report has been filed. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2020 through 2022. Discovery is ongoing, and no audit report has been filed. Entergy Mississippi Entergy Mississippi’s rate schedules includ

Regulatory activity regarding the Tax Cuts and Jobs Act See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act), including its effects on Entergy’s and the Registrant Subsidiaries’ regulatory asset/liability for income taxes. Entergy Louisiana In an electric formula rate plan settlement approved by the LPSC in April 2018, the parties agreed that Entergy Louisiana would return to customers one-half of its eligible unprotected excess deferred income taxes from May 2018 through December 2018 and return to customers the other half from January 2019 through August 2022. In addition, the settlement provided that in order to flow back to customers certain other tax benefits created by the Tax Act, Entergy Louisiana established a regulatory liability effective January 1, 2018 in the amount of $9.1 million per month to reflect these tax benefits already included in retail rates until new base rates under the formula rate plan were established in September 2018, and this regulatory liability was returned to customers over the September 2018 through August 2019 formula rate plan rate-effective period. The LPSC staff and intervenors in the settlement reserved the right to obtain data from Entergy Louisiana to confirm the determination of excess accumulated deferred income taxes resulting from the Tax Act and the analysis thereof as part of the formula rate plan review proceeding for the 2017 test year filing. As discussed below in “ Retail Rate Proceedings - Filings with the LPSC (Entergy Louisiana) - Retail Rates - Electric - Formula Rate Plan Global Settlement”, a global settlement resolving the outstanding issues related to the 2017 formula rate plan filing was reached in October 2023 and approved by the LPSC in November 2023. System Energy In a filing made with the FERC in March 2018, System Energy proposed revisions to the Unit Power Sales Agreement to reflect the effects of the Tax Act. In the filing System Energy proposed to return identified quantities of unprotected excess accumulated deferred income taxes to its customers by the end of 2018. In May 2018 the FERC accepted System Energy’s proposed tax revisions with an effective date of June 1, 2018, subject to refund and the outcome of settlement and hearing procedures. Settlement discussions were terminated in April 2019, and a hearing was held in March 2020. In December 2022 the FERC issued an order requiring System Energy to compute the amount of excess accumulated deferred income taxes associated with a previously uncertain decommissioning tax position with consideration for the resolution of the tax position by the IRS. In February 2023, System Energy submitted its compliance filing. This matter was ultimately settled as a result of System Energy’s settlements with the MPSC, the APSC, the City Council, and the LPSC. See “ Complaints Against System Energy ” below for further discussion of the System Energy settlements with the MPSC, the APSC, the City Council, and the LPSC. Fuel and purchased power cost recovery The Utility operating companies are allowed to recover fuel and purchased power costs through fuel mechanisms included in electric and gas rates that are recorded as fuel cost recovery revenues. The difference between revenues collected and the current fuel and purchased power costs is generally recorded as “Deferred fuel costs” on the Utility operating companies’ financial statements. The table below shows the amount of deferred fuel costs as of December 31, 2024 and 2023 that each Utility operating company expects to recover (or return to customers) through fuel mechanisms, subject to subsequent regulatory review. 2024 2023 (In Millions) Entergy Arkansas ($45.2) ($88.3) Entergy Louisiana (a) (b) $163.4 $192.9 Entergy Mississippi ($126.3) ($130.6) Entergy New Orleans (a) (b) $8.0 $10.2 Entergy Texas ($59.3) $139.0 (a) Includes $168.1 million in both years for Entergy Louisiana and $4.1 million in both years for Entergy New Orleans of fuel, purchased power, and capacity costs, which do not currently earn a return on investment and whose recovery periods are indeterminate but are expected to be recovered over a period greater than twelve months. (b) Includes $0.7 million at Entergy Louisiana and $4.9 million at Entergy New Orleans as of December 31, 2024 of deferred fuel assets related to the respective natural gas distribution businesses classified as held for sale and included within “Current assets held for sale” on the respective consolidated balance sheets. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Entergy Arkansas Energy Cost Recovery Rider Entergy Arkansas’s retail rates include an energy cost recovery rider to recover fuel and purchased energy costs in monthly customer bills. The rider utilizes the prior calendar-year energy costs and projected energy sales for the twelve-month period commencing on April 1 of each year to develop an energy cost rate, which is redetermined annually and includes a true-up adjustment reflecting the over- or under-recovery, including carrying charges, of the energy costs for the prior calendar year. The energy cost recovery rider tariff also allows an interim rate request depending upon the level of over- or under-recovery of fuel and purchased energy costs. In January 2014, Entergy Arkansas filed a motion with the APSC relating to its upcoming energy cost rate redetermination filing that was made in March 2014. In that motion, Entergy Arkansas requested that the APSC authorize Entergy Arkansas to exclude from the redetermination of its 2014 energy cost rate $65.9 million of incremental fuel and replacement energy costs incurred in 2013 as a result of the ANO stator incident. Entergy Arkansas requested that the APSC authorize Entergy Arkansas to retain that amount in its deferred fuel balance, with recovery to be reviewed in a later period after more information was available regarding various claims associated with the ANO stator incident. In February 2014 the APSC approved Entergy Arkansas’s request to retain that amount in its deferred fuel balance. In July 2017, Entergy Arkansas filed for a change in rates pursuant to its formula rate plan rider. In that proceeding, the APSC approved a settlement agreement agreed upon by the parties, including a provision that requires Entergy Arkansas to initiate a regulatory proceeding for the purpose of recovering funds currently withheld from rates and related to the stator incident, including the $65.9 million of deferred fuel and purchased energy costs and costs related to the incremental oversight previously noted, subject to certain timelines and conditions set forth in the settlement agreement. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the incremental fuel and purchased energy expense, among other identified costs, resulting from the ANO stator incident. As a result, in third quarter 2023, Entergy Arkansas recorded a write-off of its regulatory asset for deferred fuel of $68.9 million, which includes interest, related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. See the “ ANO Damage, Outage, and NRC Reviews ” section in Note 8 to the financial statements for further discussion of the ANO stator incident and the approved motion to forgo recovery . In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh. The APSC staff filed testimony in March 2017 recommending that the redetermined rate be implemented with the first billing cycle of April 2017 under the normal operation of the tariff. Accordingly, the redetermined rate went into effect on March 31, 2017 pursuant to the tariff. In July 2017 the Arkansas Attorney General requested additional information to support certain of the costs included in Entergy Arkansas’s 2017 energy cost rate redetermination. In March 2018, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01547 per kWh to $0.01882 per kWh. The Arkansas Attorney General filed a response to Entergy Arkansas’s annual redetermination filing requesting that the APSC suspend the proposed tariff to investigate the amount of the redetermination or, alternatively, to allow recovery subject to refund. Among the reasons the Attorney General cited for suspension were questions pertaining to how Entergy Arkansas forecasted sales and potential implications of the Tax Cuts and Jobs Act. Entergy Arkansas replied to the Attorney General’s filing and stated that, to the extent there are questions pertaining to its load forecasting or the operation of the energy cost recovery rider, those issues exceed the scope of the instant rate redetermination. Entergy Arkansas also stated that potential effects of the Tax Cuts and Jobs Act are appropriately considered in the APSC’s separate proceeding regarding potential implications of the tax law. The APSC general staff filed a reply to the Attorney General’s filing and agreed that Entergy Arkansas’s filing complied with the terms of the energy cost recovery rider. The redetermined rate became effective with the first billing cycle of April 2018. Subsequently in April 2018 the APSC issued an order declining to suspend Entergy Arkansas’s energy cost recovery rider rate and declining to require further investigation at that time of the issues suggested by the Attorney General in the proceeding. Following a period of discovery, the Attorney General filed a supplemental response in October 2018 raising new issues with Entergy Arkansas’s March 2018 rate redetermination and asserting that $45.7 million of the increase should be collected subject to refund pending further investigation. Entergy Arkansas filed to dismiss the Attorney General’s supplemental response, the APSC general staff filed a motion to strike the Attorney General’s filing, and the Attorney General filed a supplemental response disputing Entergy Arkansas and the APSC staff’s filing. Applicable APSC rules and processes authorize its general staff to initiate periodic audits of Entergy Arkansas’s energy cost recovery rider. In late-2018 the APSC general staff notified Entergy Arkansas it initiated an audit of the 2017 fuel costs. The time in which the audit will be complete is uncertain at this time. In March 2022, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00959 per kWh to $0.01785 per kWh. The primary reason for the rate increase was a large under-recovered balance as a result of higher natural gas prices in 2021, particularly in the fourth quarter 2021. At the request of the APSC general staff, Entergy Arkansas deferred its request for recovery of $32 million from the under-recovery related to the February 2021 winter storms until the 2023 energy cost rate redetermination, unless a request for an interim adjustment to the energy cost recovery rider is necessary. This resulted in a redetermined rate of $0.016390 per kWh, which became effective with the first billing cycle in April 2022 through the normal operation of the tariff. In February 2023 the APSC issued orders initiating proceedings with the utilities under its jurisdiction to address the prudence of costs incurred and appropriate cost allocation of the February 2021 winter storms. With respect to any prudence review of Entergy Arkansas fuel costs, as part of the APSC’s draft report issued in its February 2021 winter storms investigation docket, the APSC included findings that the load shedding plans of the investor-owned utilities and some cooperatives were appropriate and comprehensive, and, further, that Entergy Arkansas’s emergency plan was comprehensive and had a multilayered approach supported by a system-wide response plan, which is considered an industry standard. In September 2023 the APSC issued an order in Entergy Arkansas's company-specific proceeding and found that Entergy Arkansas’s practices during the winter storms were prudent. In March 2023, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01639 per kWh to $0.01883 per kWh. The primary reason for the rate increase is a large under-recovered balance as a result of higher natural gas prices in 2022 and a $32 million deferral related to the February 2021 winter storms consistent with the APSC general staff’s request in 2022. The under-recovered balance included in the filing was partially offset by the proceeds of the $41.7 million refund that System Energy made to Entergy Arkansas in January 2023 related to the sale-leaseback renewal costs and depreciation litigation as calculated in System Energy’s January 2023 compliance report filed with the FERC. See “ Complaints Against System Energy - Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue ” below for discussion of the compliance report filed by System Energy with the FERC in January 2023. The redetermined rate of $0.01883 per kWh became effective with the first billing cycle in April 2023 through the normal operation of the tariff. In March 2024, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected a decrease in the rate from $0.01883 per kWh to $0.00882 per kWh. Due to a change in law in the State of Arkansas, the annual redetermination included $9 million, recorded as a credit to fuel expense in first quarter 2024, for recovery attributed to net metering costs in 2023. The primary reason for the rate decrease is a large over-recovered balance as a result of lower natural gas prices in 2023. To mitigate the effect of projected increases in natural gas prices in 2024, Entergy Arkansas adjusted the over-recovered balance included in the March 2024 annual redetermination filing by $43.7 million. This adjustment is expected to reduce the rate change that will be reflected in the 2025 energy cost rate redetermination. The redetermined rate of $0.00882 per kWh became effective with the first billing cycle in April 2024 through the normal operation of the tariff. Entergy Louisiana Entergy Louisiana recovers electric fuel and purchased power costs for the billing month based upon the level of such costs incurred two months prior to the billing month. Entergy Louisiana’s purchased gas adjustments include estimates for the billing month adjusted by a surcharge or credit that arises from an annual reconciliation of fuel costs incurred with fuel cost revenues billed to customers, including carrying charges. To mitigate high electric bills, primarily driven by high summer usage and elevated gas prices, Entergy Louisiana deferred approximately $225 million of fuel expense incurred in April, May, June, July, August, and September 2022 (as reflected on June, July, August, September, October, and November 2022 bills). These deferrals were included in the over/under calculation of the fuel adjustment clause, which is intended to recover the full amount of the costs included on a rolling twelve-month basis. In March 2020 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2016 through 2019. The LPSC staff issued its audit report in September 2021, and although certain internal record keeping recommendations were made, the LPSC staff did not recommend any disallowances. The next step is for the LPSC to review the report, but there is not a deadline for the review. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. Discovery is ongoing, and no audit report has been filed. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2020 through 2022. Discovery is ongoing, and no audit report has been filed. Entergy Mississippi Entergy Mississippi’s rate schedules includ

Regulatory activity regarding the Tax Cuts and Jobs Act See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act), including its effects on Entergy’s and the Registrant Subsidiaries’ regulatory asset/liability for income taxes. Entergy Louisiana In an electric formula rate plan settlement approved by the LPSC in April 2018, the parties agreed that Entergy Louisiana would return to customers one-half of its eligible unprotected excess deferred income taxes from May 2018 through December 2018 and return to customers the other half from January 2019 through August 2022. In addition, the settlement provided that in order to flow back to customers certain other tax benefits created by the Tax Act, Entergy Louisiana established a regulatory liability effective January 1, 2018 in the amount of $9.1 million per month to reflect these tax benefits already included in retail rates until new base rates under the formula rate plan were established in September 2018, and this regulatory liability was returned to customers over the September 2018 through August 2019 formula rate plan rate-effective period. The LPSC staff and intervenors in the settlement reserved the right to obtain data from Entergy Louisiana to confirm the determination of excess accumulated deferred income taxes resulting from the Tax Act and the analysis thereof as part of the formula rate plan review proceeding for the 2017 test year filing. As discussed below in “ Retail Rate Proceedings - Filings with the LPSC (Entergy Louisiana) - Retail Rates - Electric - Formula Rate Plan Global Settlement”, a global settlement resolving the outstanding issues related to the 2017 formula rate plan filing was reached in October 2023 and approved by the LPSC in November 2023. System Energy In a filing made with the FERC in March 2018, System Energy proposed revisions to the Unit Power Sales Agreement to reflect the effects of the Tax Act. In the filing System Energy proposed to return identified quantities of unprotected excess accumulated deferred income taxes to its customers by the end of 2018. In May 2018 the FERC accepted System Energy’s proposed tax revisions with an effective date of June 1, 2018, subject to refund and the outcome of settlement and hearing procedures. Settlement discussions were terminated in April 2019, and a hearing was held in March 2020. In December 2022 the FERC issued an order requiring System Energy to compute the amount of excess accumulated deferred income taxes associated with a previously uncertain decommissioning tax position with consideration for the resolution of the tax position by the IRS. In February 2023, System Energy submitted its compliance filing. This matter was ultimately settled as a result of System Energy’s settlements with the MPSC, the APSC, the City Council, and the LPSC. See “ Complaints Against System Energy ” below for further discussion of the System Energy settlements with the MPSC, the APSC, the City Council, and the LPSC. Fuel and purchased power cost recovery The Utility operating companies are allowed to recover fuel and purchased power costs through fuel mechanisms included in electric and gas rates that are recorded as fuel cost recovery revenues. The difference between revenues collected and the current fuel and purchased power costs is generally recorded as “Deferred fuel costs” on the Utility operating companies’ financial statements. The table below shows the amount of deferred fuel costs as of December 31, 2024 and 2023 that each Utility operating company expects to recover (or return to customers) through fuel mechanisms, subject to subsequent regulatory review. 2024 2023 (In Millions) Entergy Arkansas ($45.2) ($88.3) Entergy Louisiana (a) (b) $163.4 $192.9 Entergy Mississippi ($126.3) ($130.6) Entergy New Orleans (a) (b) $8.0 $10.2 Entergy Texas ($59.3) $139.0 (a) Includes $168.1 million in both years for Entergy Louisiana and $4.1 million in both years for Entergy New Orleans of fuel, purchased power, and capacity costs, which do not currently earn a return on investment and whose recovery periods are indeterminate but are expected to be recovered over a period greater than twelve months. (b) Includes $0.7 million at Entergy Louisiana and $4.9 million at Entergy New Orleans as of December 31, 2024 of deferred fuel assets related to the respective natural gas distribution businesses classified as held for sale and included within “Current assets held for sale” on the respective consolidated balance sheets. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Entergy Arkansas Energy Cost Recovery Rider Entergy Arkansas’s retail rates include an energy cost recovery rider to recover fuel and purchased energy costs in monthly customer bills. The rider utilizes the prior calendar-year energy costs and projected energy sales for the twelve-month period commencing on April 1 of each year to develop an energy cost rate, which is redetermined annually and includes a true-up adjustment reflecting the over- or under-recovery, including carrying charges, of the energy costs for the prior calendar year. The energy cost recovery rider tariff also allows an interim rate request depending upon the level of over- or under-recovery of fuel and purchased energy costs. In January 2014, Entergy Arkansas filed a motion with the APSC relating to its upcoming energy cost rate redetermination filing that was made in March 2014. In that motion, Entergy Arkansas requested that the APSC authorize Entergy Arkansas to exclude from the redetermination of its 2014 energy cost rate $65.9 million of incremental fuel and replacement energy costs incurred in 2013 as a result of the ANO stator incident. Entergy Arkansas requested that the APSC authorize Entergy Arkansas to retain that amount in its deferred fuel balance, with recovery to be reviewed in a later period after more information was available regarding various claims associated with the ANO stator incident. In February 2014 the APSC approved Entergy Arkansas’s request to retain that amount in its deferred fuel balance. In July 2017, Entergy Arkansas filed for a change in rates pursuant to its formula rate plan rider. In that proceeding, the APSC approved a settlement agreement agreed upon by the parties, including a provision that requires Entergy Arkansas to initiate a regulatory proceeding for the purpose of recovering funds currently withheld from rates and related to the stator incident, including the $65.9 million of deferred fuel and purchased energy costs and costs related to the incremental oversight previously noted, subject to certain timelines and conditions set forth in the settlement agreement. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the incremental fuel and purchased energy expense, among other identified costs, resulting from the ANO stator incident. As a result, in third quarter 2023, Entergy Arkansas recorded a write-off of its regulatory asset for deferred fuel of $68.9 million, which includes interest, related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. See the “ ANO Damage, Outage, and NRC Reviews ” section in Note 8 to the financial statements for further discussion of the ANO stator incident and the approved motion to forgo recovery . In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh. The APSC staff filed testimony in March 2017 recommending that the redetermined rate be implemented with the first billing cycle of April 2017 under the normal operation of the tariff. Accordingly, the redetermined rate went into effect on March 31, 2017 pursuant to the tariff. In July 2017 the Arkansas Attorney General requested additional information to support certain of the costs included in Entergy Arkansas’s 2017 energy cost rate redetermination. In March 2018, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01547 per kWh to $0.01882 per kWh. The Arkansas Attorney General filed a response to Entergy Arkansas’s annual redetermination filing requesting that the APSC suspend the proposed tariff to investigate the amount of the redetermination or, alternatively, to allow recovery subject to refund. Among the reasons the Attorney General cited for suspension were questions pertaining to how Entergy Arkansas forecasted sales and potential implications of the Tax Cuts and Jobs Act. Entergy Arkansas replied to the Attorney General’s filing and stated that, to the extent there are questions pertaining to its load forecasting or the operation of the energy cost recovery rider, those issues exceed the scope of the instant rate redetermination. Entergy Arkansas also stated that potential effects of the Tax Cuts and Jobs Act are appropriately considered in the APSC’s separate proceeding regarding potential implications of the tax law. The APSC general staff filed a reply to the Attorney General’s filing and agreed that Entergy Arkansas’s filing complied with the terms of the energy cost recovery rider. The redetermined rate became effective with the first billing cycle of April 2018. Subsequently in April 2018 the APSC issued an order declining to suspend Entergy Arkansas’s energy cost recovery rider rate and declining to require further investigation at that time of the issues suggested by the Attorney General in the proceeding. Following a period of discovery, the Attorney General filed a supplemental response in October 2018 raising new issues with Entergy Arkansas’s March 2018 rate redetermination and asserting that $45.7 million of the increase should be collected subject to refund pending further investigation. Entergy Arkansas filed to dismiss the Attorney General’s supplemental response, the APSC general staff filed a motion to strike the Attorney General’s filing, and the Attorney General filed a supplemental response disputing Entergy Arkansas and the APSC staff’s filing. Applicable APSC rules and processes authorize its general staff to initiate periodic audits of Entergy Arkansas’s energy cost recovery rider. In late-2018 the APSC general staff notified Entergy Arkansas it initiated an audit of the 2017 fuel costs. The time in which the audit will be complete is uncertain at this time. In March 2022, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00959 per kWh to $0.01785 per kWh. The primary reason for the rate increase was a large under-recovered balance as a result of higher natural gas prices in 2021, particularly in the fourth quarter 2021. At the request of the APSC general staff, Entergy Arkansas deferred its request for recovery of $32 million from the under-recovery related to the February 2021 winter storms until the 2023 energy cost rate redetermination, unless a request for an interim adjustment to the energy cost recovery rider is necessary. This resulted in a redetermined rate of $0.016390 per kWh, which became effective with the first billing cycle in April 2022 through the normal operation of the tariff. In February 2023 the APSC issued orders initiating proceedings with the utilities under its jurisdiction to address the prudence of costs incurred and appropriate cost allocation of the February 2021 winter storms. With respect to any prudence review of Entergy Arkansas fuel costs, as part of the APSC’s draft report issued in its February 2021 winter storms investigation docket, the APSC included findings that the load shedding plans of the investor-owned utilities and some cooperatives were appropriate and comprehensive, and, further, that Entergy Arkansas’s emergency plan was comprehensive and had a multilayered approach supported by a system-wide response plan, which is considered an industry standard. In September 2023 the APSC issued an order in Entergy Arkansas's company-specific proceeding and found that Entergy Arkansas’s practices during the winter storms were prudent. In March 2023, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01639 per kWh to $0.01883 per kWh. The primary reason for the rate increase is a large under-recovered balance as a result of higher natural gas prices in 2022 and a $32 million deferral related to the February 2021 winter storms consistent with the APSC general staff’s request in 2022. The under-recovered balance included in the filing was partially offset by the proceeds of the $41.7 million refund that System Energy made to Entergy Arkansas in January 2023 related to the sale-leaseback renewal costs and depreciation litigation as calculated in System Energy’s January 2023 compliance report filed with the FERC. See “ Complaints Against System Energy - Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue ” below for discussion of the compliance report filed by System Energy with the FERC in January 2023. The redetermined rate of $0.01883 per kWh became effective with the first billing cycle in April 2023 through the normal operation of the tariff. In March 2024, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected a decrease in the rate from $0.01883 per kWh to $0.00882 per kWh. Due to a change in law in the State of Arkansas, the annual redetermination included $9 million, recorded as a credit to fuel expense in first quarter 2024, for recovery attributed to net metering costs in 2023. The primary reason for the rate decrease is a large over-recovered balance as a result of lower natural gas prices in 2023. To mitigate the effect of projected increases in natural gas prices in 2024, Entergy Arkansas adjusted the over-recovered balance included in the March 2024 annual redetermination filing by $43.7 million. This adjustment is expected to reduce the rate change that will be reflected in the 2025 energy cost rate redetermination. The redetermined rate of $0.00882 per kWh became effective with the first billing cycle in April 2024 through the normal operation of the tariff. Entergy Louisiana Entergy Louisiana recovers electric fuel and purchased power costs for the billing month based upon the level of such costs incurred two months prior to the billing month. Entergy Louisiana’s purchased gas adjustments include estimates for the billing month adjusted by a surcharge or credit that arises from an annual reconciliation of fuel costs incurred with fuel cost revenues billed to customers, including carrying charges. To mitigate high electric bills, primarily driven by high summer usage and elevated gas prices, Entergy Louisiana deferred approximately $225 million of fuel expense incurred in April, May, June, July, August, and September 2022 (as reflected on June, July, August, September, October, and November 2022 bills). These deferrals were included in the over/under calculation of the fuel adjustment clause, which is intended to recover the full amount of the costs included on a rolling twelve-month basis. In March 2020 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2016 through 2019. The LPSC staff issued its audit report in September 2021, and although certain internal record keeping recommendations were made, the LPSC staff did not recommend any disallowances. The next step is for the LPSC to review the report, but there is not a deadline for the review.

Public Utilities Disclosure [Text Block]	RATE AND REGULATORY MATTERS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Regulatory Assets and Regulatory Liabilities Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. In addition to the regulatory assets and liabilities that are specifically disclosed on the face of the balance sheets, the tables below provide detail of “Other regulatory assets” and “Other regulatory liabilities” that are included on Entergy’s and the Registrant Subsidiaries’ balance sheets as of December 31, 2024 and 2023 (as noted in footnotes to the tables, a portion of these regulatory assets and regulatory liabilities is classified as held for sale in the balance sheets as of December 31, 2024): Other Regulatory Assets Entergy 2024 2023 (In Millions) Pension & postretirement costs (Note 11 -

Regulatory activity regarding the Tax Cuts and Jobs Act See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act), including its effects on Entergy’s and the Registrant Subsidiaries’ regulatory asset/liability for income taxes. Entergy Louisiana In an electric formula rate plan settlement approved by the LPSC in April 2018, the parties agreed that Entergy Louisiana would return to customers one-half of its eligible unprotected excess deferred income taxes from May 2018 through December 2018 and return to customers the other half from January 2019 through August 2022. In addition, the settlement provided that in order to flow back to customers certain other tax benefits created by the Tax Act, Entergy Louisiana established a regulatory liability effective January 1, 2018 in the amount of $9.1 million per month to reflect these tax benefits already included in retail rates until new base rates under the formula rate plan were established in September 2018, and this regulatory liability was returned to customers over the September 2018 through August 2019 formula rate plan rate-effective period. The LPSC staff and intervenors in the settlement reserved the right to obtain data from Entergy Louisiana to confirm the determination of excess accumulated deferred income taxes resulting from the Tax Act and the analysis thereof as part of the formula rate plan review proceeding for the 2017 test year filing. As discussed below in “ Retail Rate Proceedings - Filings with the LPSC (Entergy Louisiana) - Retail Rates - Electric - Formula Rate Plan Global Settlement”, a global settlement resolving the outstanding issues related to the 2017 formula rate plan filing was reached in October 2023 and approved by the LPSC in November 2023. System Energy In a filing made with the FERC in March 2018, System Energy proposed revisions to the Unit Power Sales Agreement to reflect the effects of the Tax Act. In the filing System Energy proposed to return identified quantities of unprotected excess accumulated deferred income taxes to its customers by the end of 2018. In May 2018 the FERC accepted System Energy’s proposed tax revisions with an effective date of June 1, 2018, subject to refund and the outcome of settlement and hearing procedures. Settlement discussions were terminated in April 2019, and a hearing was held in March 2020. In December 2022 the FERC issued an order requiring System Energy to compute the amount of excess accumulated deferred income taxes associated with a previously uncertain decommissioning tax position with consideration for the resolution of the tax position by the IRS. In February 2023, System Energy submitted its compliance filing. This matter was ultimately settled as a result of System Energy’s settlements with the MPSC, the APSC, the City Council, and the LPSC. See “ Complaints Against System Energy ” below for further discussion of the System Energy settlements with the MPSC, the APSC, the City Council, and the LPSC. Fuel and purchased power cost recovery The Utility operating companies are allowed to recover fuel and purchased power costs through fuel mechanisms included in electric and gas rates that are recorded as fuel cost recovery revenues. The difference between revenues collected and the current fuel and purchased power costs is generally recorded as “Deferred fuel costs” on the Utility operating companies’ financial statements. The table below shows the amount of deferred fuel costs as of December 31, 2024 and 2023 that each Utility operating company expects to recover (or return to customers) through fuel mechanisms, subject to subsequent regulatory review. 2024 2023 (In Millions) Entergy Arkansas ($45.2) ($88.3) Entergy Louisiana (a) (b) $163.4 $192.9 Entergy Mississippi ($126.3) ($130.6) Entergy New Orleans (a) (b) $8.0 $10.2 Entergy Texas ($59.3) $139.0 (a) Includes $168.1 million in both years for Entergy Louisiana and $4.1 million in both years for Entergy New Orleans of fuel, purchased power, and capacity costs, which do not currently earn a return on investment and whose recovery periods are indeterminate but are expected to be recovered over a period greater than twelve months. (b) Includes $0.7 million at Entergy Louisiana and $4.9 million at Entergy New Orleans as of December 31, 2024 of deferred fuel assets related to the respective natural gas distribution businesses classified as held for sale and included within “Current assets held for sale” on the respective consolidated balance sheets. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Entergy Arkansas Energy Cost Recovery Rider Entergy Arkansas’s retail rates include an energy cost recovery rider to recover fuel and purchased energy costs in monthly customer bills. The rider utilizes the prior calendar-year energy costs and projected energy sales for the twelve-month period commencing on April 1 of each year to develop an energy cost rate, which is redetermined annually and includes a true-up adjustment reflecting the over- or under-recovery, including carrying charges, of the energy costs for the prior calendar year. The energy cost recovery rider tariff also allows an interim rate request depending upon the level of over- or under-recovery of fuel and purchased energy costs. In January 2014, Entergy Arkansas filed a motion with the APSC relating to its upcoming energy cost rate redetermination filing that was made in March 2014. In that motion, Entergy Arkansas requested that the APSC authorize Entergy Arkansas to exclude from the redetermination of its 2014 energy cost rate $65.9 million of incremental fuel and replacement energy costs incurred in 2013 as a result of the ANO stator incident. Entergy Arkansas requested that the APSC authorize Entergy Arkansas to retain that amount in its deferred fuel balance, with recovery to be reviewed in a later period after more information was available regarding various claims associated with the ANO stator incident. In February 2014 the APSC approved Entergy Arkansas’s request to retain that amount in its deferred fuel balance. In July 2017, Entergy Arkansas filed for a change in rates pursuant to its formula rate plan rider. In that proceeding, the APSC approved a settlement agreement agreed upon by the parties, including a provision that requires Entergy Arkansas to initiate a regulatory proceeding for the purpose of recovering funds currently withheld from rates and related to the stator incident, including the $65.9 million of deferred fuel and purchased energy costs and costs related to the incremental oversight previously noted, subject to certain timelines and conditions set forth in the settlement agreement. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the incremental fuel and purchased energy expense, among other identified costs, resulting from the ANO stator incident. As a result, in third quarter 2023, Entergy Arkansas recorded a write-off of its regulatory asset for deferred fuel of $68.9 million, which includes interest, related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. See the “ ANO Damage, Outage, and NRC Reviews ” section in Note 8 to the financial statements for further discussion of the ANO stator incident and the approved motion to forgo recovery . In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh. The APSC staff filed testimony in March 2017 recommending that the redetermined rate be implemented with the first billing cycle of April 2017 under the normal operation of the tariff. Accordingly, the redetermined rate went into effect on March 31, 2017 pursuant to the tariff. In July 2017 the Arkansas Attorney General requested additional information to support certain of the costs included in Entergy Arkansas’s 2017 energy cost rate redetermination. In March 2018, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01547 per kWh to $0.01882 per kWh. The Arkansas Attorney General filed a response to Entergy Arkansas’s annual redetermination filing requesting that the APSC suspend the proposed tariff to investigate the amount of the redetermination or, alternatively, to allow recovery subject to refund. Among the reasons the Attorney General cited for suspension were questions pertaining to how Entergy Arkansas forecasted sales and potential implications of the Tax Cuts and Jobs Act. Entergy Arkansas replied to the Attorney General’s filing and stated that, to the extent there are questions pertaining to its load forecasting or the operation of the energy cost recovery rider, those issues exceed the scope of the instant rate redetermination. Entergy Arkansas also stated that potential effects of the Tax Cuts and Jobs Act are appropriately considered in the APSC’s separate proceeding regarding potential implications of the tax law. The APSC general staff filed a reply to the Attorney General’s filing and agreed that Entergy Arkansas’s filing complied with the terms of the energy cost recovery rider. The redetermined rate became effective with the first billing cycle of April 2018. Subsequently in April 2018 the APSC issued an order declining to suspend Entergy Arkansas’s energy cost recovery rider rate and declining to require further investigation at that time of the issues suggested by the Attorney General in the proceeding. Following a period of discovery, the Attorney General filed a supplemental response in October 2018 raising new issues with Entergy Arkansas’s March 2018 rate redetermination and asserting that $45.7 million of the increase should be collected subject to refund pending further investigation. Entergy Arkansas filed to dismiss the Attorney General’s supplemental response, the APSC general staff filed a motion to strike the Attorney General’s filing, and the Attorney General filed a supplemental response disputing Entergy Arkansas and the APSC staff’s filing. Applicable APSC rules and processes authorize its general staff to initiate periodic audits of Entergy Arkansas’s energy cost recovery rider. In late-2018 the APSC general staff notified Entergy Arkansas it initiated an audit of the 2017 fuel costs. The time in which the audit will be complete is uncertain at this time. In March 2022, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00959 per kWh to $0.01785 per kWh. The primary reason for the rate increase was a large under-recovered balance as a result of higher natural gas prices in 2021, particularly in the fourth quarter 2021. At the request of the APSC general staff, Entergy Arkansas deferred its request for recovery of $32 million from the under-recovery related to the February 2021 winter storms until the 2023 energy cost rate redetermination, unless a request for an interim adjustment to the energy cost recovery rider is necessary. This resulted in a redetermined rate of $0.016390 per kWh, which became effective with the first billing cycle in April 2022 through the normal operation of the tariff. In February 2023 the APSC issued orders initiating proceedings with the utilities under its jurisdiction to address the prudence of costs incurred and appropriate cost allocation of the February 2021 winter storms. With respect to any prudence review of Entergy Arkansas fuel costs, as part of the APSC’s draft report issued in its February 2021 winter storms investigation docket, the APSC included findings that the load shedding plans of the investor-owned utilities and some cooperatives were appropriate and comprehensive, and, further, that Entergy Arkansas’s emergency plan was comprehensive and had a multilayered approach supported by a system-wide response plan, which is considered an industry standard. In September 2023 the APSC issued an order in Entergy Arkansas's company-specific proceeding and found that Entergy Arkansas’s practices during the winter storms were prudent. In March 2023, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01639 per kWh to $0.01883 per kWh. The primary reason for the rate increase is a large under-recovered balance as a result of higher natural gas prices in 2022 and a $32 million deferral related to the February 2021 winter storms consistent with the APSC general staff’s request in 2022. The under-recovered balance included in the filing was partially offset by the proceeds of the $41.7 million refund that System Energy made to Entergy Arkansas in January 2023 related to the sale-leaseback renewal costs and depreciation litigation as calculated in System Energy’s January 2023 compliance report filed with the FERC. See “ Complaints Against System Energy - Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue ” below for discussion of the compliance report filed by System Energy with the FERC in January 2023. The redetermined rate of $0.01883 per kWh became effective with the first billing cycle in April 2023 through the normal operation of the tariff. In March 2024, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected a decrease in the rate from $0.01883 per kWh to $0.00882 per kWh. Due to a change in law in the State of Arkansas, the annual redetermination included $9 million, recorded as a credit to fuel expense in first quarter 2024, for recovery attributed to net metering costs in 2023. The primary reason for the rate decrease is a large over-recovered balance as a result of lower natural gas prices in 2023. To mitigate the effect of projected increases in natural gas prices in 2024, Entergy Arkansas adjusted the over-recovered balance included in the March 2024 annual redetermination filing by $43.7 million. This adjustment is expected to reduce the rate change that will be reflected in the 2025 energy cost rate redetermination. The redetermined rate of $0.00882 per kWh became effective with the first billing cycle in April 2024 through the normal operation of the tariff. Entergy Louisiana Entergy Louisiana recovers electric fuel and purchased power costs for the billing month based upon the level of such costs incurred two months prior to the billing month. Entergy Louisiana’s purchased gas adjustments include estimates for the billing month adjusted by a surcharge or credit that arises from an annual reconciliation of fuel costs incurred with fuel cost revenues billed to customers, including carrying charges. To mitigate high electric bills, primarily driven by high summer usage and elevated gas prices, Entergy Louisiana deferred approximately $225 million of fuel expense incurred in April, May, June, July, August, and September 2022 (as reflected on June, July, August, September, October, and November 2022 bills). These deferrals were included in the over/under calculation of the fuel adjustment clause, which is intended to recover the full amount of the costs included on a rolling twelve-month basis. In March 2020 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2016 through 2019. The LPSC staff issued its audit report in September 2021, and although certain internal record keeping recommendations were made, the LPSC staff did not recommend any disallowances. The next step is for the LPSC to review the report, but there is not a deadline for the review. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. Discovery is ongoing, and no audit report has been filed. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings.

Regulatory activity regarding the Tax Cuts and Jobs Act See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act), including its effects on Entergy’s and the Registrant Subsidiaries’ regulatory asset/liability for income taxes. Entergy Louisiana In an electric formula rate plan settlement approved by the LPSC in April 2018, the parties agreed that Entergy Louisiana would return to customers one-half of its eligible unprotected excess deferred income taxes from May 2018 through December 2018 and return to customers the other half from January 2019 through August 2022. In addition, the settlement provided that in order to flow back to customers certain other tax benefits created by the Tax Act, Entergy Louisiana established a regulatory liability effective January 1, 2018 in the amount of $9.1 million per month to reflect these tax benefits already included in retail rates until new base rates under the formula rate plan were established in September 2018, and this regulatory liability was returned to customers over the September 2018 through August 2019 formula rate plan rate-effective period. The LPSC staff and intervenors in the settlement reserved the right to obtain data from Entergy Louisiana to confirm the determination of excess accumulated deferred income taxes resulting from the Tax Act and the analysis thereof as part of the formula rate plan review proceeding for the 2017 test year filing. As discussed below in “ Retail Rate Proceedings - Filings with the LPSC (Entergy Louisiana) - Retail Rates - Electric - Formula Rate Plan Global Settlement”, a global settlement resolving the outstanding issues related to the 2017 formula rate plan filing was reached in October 2023 and approved by the LPSC in November 2023. System Energy In a filing made with the FERC in March 2018, System Energy proposed revisions to the Unit Power Sales Agreement to reflect the effects of the Tax Act. In the filing System Energy proposed to return identified quantities of unprotected excess accumulated deferred income taxes to its customers by the end of 2018. In May 2018 the FERC accepted System Energy’s proposed tax revisions with an effective date of June 1, 2018, subject to refund and the outcome of settlement and hearing procedures. Settlement discussions were terminated in April 2019, and a hearing was held in March 2020. In December 2022 the FERC issued an order requiring System Energy to compute the amount of excess accumulated deferred income taxes associated with a previously uncertain decommissioning tax position with consideration for the resolution of the tax position by the IRS. In February 2023, System Energy submitted its compliance filing. This matter was ultimately settled as a result of System Energy’s settlements with the MPSC, the APSC, the City Council, and the LPSC. See “ Complaints Against System Energy ” below for further discussion of the System Energy settlements with the MPSC, the APSC, the City Council, and the LPSC. Fuel and purchased power cost recovery The Utility operating companies are allowed to recover fuel and purchased power costs through fuel mechanisms included in electric and gas rates that are recorded as fuel cost recovery revenues. The difference between revenues collected and the current fuel and purchased power costs is generally recorded as “Deferred fuel costs” on the Utility operating companies’ financial statements. The table below shows the amount of deferred fuel costs as of December 31, 2024 and 2023 that each Utility operating company expects to recover (or return to customers) through fuel mechanisms, subject to subsequent regulatory review. 2024 2023 (In Millions) Entergy Arkansas ($45.2) ($88.3) Entergy Louisiana (a) (b) $163.4 $192.9 Entergy Mississippi ($126.3) ($130.6) Entergy New Orleans (a) (b) $8.0 $10.2 Entergy Texas ($59.3) $139.0 (a) Includes $168.1 million in both years for Entergy Louisiana and $4.1 million in both years for Entergy New Orleans of fuel, purchased power, and capacity costs, which do not currently earn a return on investment and whose recovery periods are indeterminate but are expected to be recovered over a period greater than twelve months. (b) Includes $0.7 million at Entergy Louisiana and $4.9 million at Entergy New Orleans as of December 31, 2024 of deferred fuel assets related to the respective natural gas distribution businesses classified as held for sale and included within “Current assets held for sale” on the respective consolidated balance sheets. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Entergy Arkansas Energy Cost Recovery Rider Entergy Arkansas’s retail rates include an energy cost recovery rider to recover fuel and purchased energy costs in monthly customer bills. The rider utilizes the prior calendar-year energy costs and projected energy sales for the twelve-month period commencing on April 1 of each year to develop an energy cost rate, which is redetermined annually and includes a true-up adjustment reflecting the over- or under-recovery, including carrying charges, of the energy costs for the prior calendar year. The energy cost recovery rider tariff also allows an interim rate request depending upon the level of over- or under-recovery of fuel and purchased energy costs. In January 2014, Entergy Arkansas filed a motion with the APSC relating to its upcoming energy cost rate redetermination filing that was made in March 2014. In that motion, Entergy Arkansas requested that the APSC authorize Entergy Arkansas to exclude from the redetermination of its 2014 energy cost rate $65.9 million of incremental fuel and replacement energy costs incurred in 2013 as a result of the ANO stator incident. Entergy Arkansas requested that the APSC authorize Entergy Arkansas to retain that amount in its deferred fuel balance, with recovery to be reviewed in a later period after more information was available regarding various claims associated with the ANO stator incident. In February 2014 the APSC approved Entergy Arkansas’s request to retain that amount in its deferred fuel balance. In July 2017, Entergy Arkansas filed for a change in rates pursuant to its formula rate plan rider. In that proceeding, the APSC approved a settlement agreement agreed upon by the parties, including a provision that requires Entergy Arkansas to initiate a regulatory proceeding for the purpose of recovering funds currently withheld from rates and related to the stator incident, including the $65.9 million of deferred fuel and purchased energy costs and costs related to the incremental oversight previously noted, subject to certain timelines and conditions set forth in the settlement agreement. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the incremental fuel and purchased energy expense, among other identified costs, resulting from the ANO stator incident. As a result, in third quarter 2023, Entergy Arkansas recorded a write-off of its regulatory asset for deferred fuel of $68.9 million, which includes interest, related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. See the “ ANO Damage, Outage, and NRC Reviews ” section in Note 8 to the financial statements for further discussion of the ANO stator incident and the approved motion to forgo recovery . In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh. The APSC staff filed testimony in March 2017 recommending that the redetermined rate be implemented with the first billing cycle of April 2017 under the normal operation of the tariff. Accordingly, the redetermined rate went into effect on March 31, 2017 pursuant to the tariff. In July 2017 the Arkansas Attorney General requested additional information to support certain of the costs included in Entergy Arkansas’s 2017 energy cost rate redetermination. In March 2018, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01547 per kWh to $0.01882 per kWh. The Arkansas Attorney General filed a response to Entergy Arkansas’s annual redetermination filing requesting that the APSC suspend the proposed tariff to investigate the amount of the redetermination or, alternatively, to allow recovery subject to refund. Among the reasons the Attorney General cited for suspension were questions pertaining to how Entergy Arkansas forecasted sales and potential implications of the Tax Cuts and Jobs Act. Entergy Arkansas replied to the Attorney General’s filing and stated that, to the extent there are questions pertaining to its load forecasting or the operation of the energy cost recovery rider, those issues exceed the scope of the instant rate redetermination. Entergy Arkansas also stated that potential effects of the Tax Cuts and Jobs Act are appropriately considered in the APSC’s separate proceeding regarding potential implications of the tax law. The APSC general staff filed a reply to the Attorney General’s filing and agreed that Entergy Arkansas’s filing complied with the terms of the energy cost recovery rider. The redetermined rate became effective with the first billing cycle of April 2018. Subsequently in April 2018 the APSC issued an order declining to suspend Entergy Arkansas’s energy cost recovery rider rate and declining to require further investigation at that time of the issues suggested by the Attorney General in the proceeding. Following a period of discovery, the Attorney General filed a supplemental response in October 2018 raising new issues with Entergy Arkansas’s March 2018 rate redetermination and asserting that $45.7 million of the increase should be collected subject to refund pending further investigation. Entergy Arkansas filed to dismiss the Attorney General’s supplemental response, the APSC general staff filed a motion to strike the Attorney General’s filing, and the Attorney General filed a supplemental response disputing Entergy Arkansas and the APSC staff’s filing. Applicable APSC rules and processes authorize its general staff to initiate periodic audits of Entergy Arkansas’s energy cost recovery rider. In late-2018 the APSC general staff notified Entergy Arkansas it initiated an audit of the 2017 fuel costs. The time in which the audit will be complete is uncertain at this time. In March 2022, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00959 per kWh to $0.01785 per kWh. The primary reason for the rate increase was a large under-recovered balance as a result of higher natural gas prices in 2021, particularly in the fourth quarter 2021. At the request of the APSC general staff, Entergy Arkansas deferred its request for recovery of $32 million from the under-recovery related to the February 2021 winter storms until the 2023 energy cost rate redetermination, unless a request for an interim adjustment to the energy cost recovery rider is necessary. This resulted in a redetermined rate of $0.016390 per kWh, which became effective with the first billing cycle in April 2022 through the normal operation of the tariff. In February 2023 the APSC issued orders initiating proceedings with the utilities under its jurisdiction to address the prudence of costs incurred and appropriate cost allocation of the February 2021 winter storms. With respect to any prudence review of Entergy Arkansas fuel costs, as part of the APSC’s draft report issued in its February 2021 winter storms investigation docket, the APSC included findings that the load shedding plans of the investor-owned utilities and some cooperatives were appropriate and comprehensive, and, further, that Entergy Arkansas’s emergency plan was comprehensive and had a multilayered approach supported by a system-wide response plan, which is considered an industry standard. In September 2023 the APSC issued an order in Entergy Arkansas's company-specific proceeding and found that Entergy Arkansas’s practices during the winter storms were prudent. In March 2023, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01639 per kWh to $0.01883 per kWh. The primary reason for the rate increase is a large under-recovered balance as a result of higher natural gas prices in 2022 and a $32 million deferral related to the February 2021 winter storms consistent with the APSC general staff’s request in 2022. The under-recovered balance included in the filing was partially offset by the proceeds of the $41.7 million refund that System Energy made to Entergy Arkansas in January 2023 related to the sale-leaseback renewal costs and depreciation litigation as calculated in System Energy’s January 2023 compliance report filed with the FERC. See “ Complaints Against System Energy - Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue ” below for discussion of the compliance report filed by System Energy with the FERC in January 2023. The redetermined rate of $0.01883 per kWh became effective with the first billing cycle in April 2023 through the normal operation of the tariff. In March 2024, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected a decrease in the rate from $0.01883 per kWh to $0.00882 per kWh. Due to a change in law in the State of Arkansas, the annual redetermination included $9 million, recorded as a credit to fuel expense in first quarter 2024, for recovery attributed to net metering costs in 2023. The primary reason for the rate decrease is a large over-recovered balance as a result of lower natural gas prices in 2023. To mitigate the effect of projected increases in natural gas prices in 2024, Entergy Arkansas adjusted the over-recovered balance included in the March 2024 annual redetermination filing by $43.7 million. This adjustment is expected to reduce the rate change that will be reflected in the 2025 energy cost rate redetermination. The redetermined rate of $0.00882 per kWh became effective with the first billing cycle in April 2024 through the normal operation of the tariff. Entergy Louisiana Entergy Louisiana recovers electric fuel and purchased power costs for the billing month based upon the level of such costs incurred two months prior to the billing month. Entergy Louisiana’s purchased gas adjustments include estimates for the billing month adjusted by a surcharge or credit that arises from an annual reconciliation of fuel costs incurred with fuel cost revenues billed to customers, including carrying charges. To mitigate high electric bills, primarily driven by high summer usage and elevated gas prices, Entergy Louisiana deferred approximately $225 million of fuel expense incurred in April, May, June, July, August, and September 2022 (as reflected on June, July, August, September, October, and November 2022 bills). These deferrals were included in the over/under calculation of the fuel adjustment clause, which is intended to recover the full amount of the costs included on a rolling twelve-month basis. In March 2020 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2016 through 2019. The LPSC staff issued its audit report in September 2021, and although certain internal record keeping recommendations were made, the LPSC staff did not recommend any disallowances. The next step is for the LPSC to review the report, but there is not a deadline for the review. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. Discovery is ongoing, and no audit report has been filed. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings.

Regulatory activity regarding the Tax Cuts and Jobs Act See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act), including its effects on Entergy’s and the Registrant Subsidiaries’ regulatory asset/liability for income taxes. Entergy Louisiana In an electric formula rate plan settlement approved by the LPSC in April 2018, the parties agreed that Entergy Louisiana would return to customers one-half of its eligible unprotected excess deferred income taxes from May 2018 through December 2018 and return to customers the other half from January 2019 through August 2022. In addition, the settlement provided that in order to flow back to customers certain other tax benefits created by the Tax Act, Entergy Louisiana established a regulatory liability effective January 1, 2018 in the amount of $9.1 million per month to reflect these tax benefits already included in retail rates until new base rates under the formula rate plan were established in September 2018, and this regulatory liability was returned to customers over the September 2018 through August 2019 formula rate plan rate-effective period. The LPSC staff and intervenors in the settlement reserved the right to obtain data from Entergy Louisiana to confirm the determination of excess accumulated deferred income taxes resulting from the Tax Act and the analysis thereof as part of the formula rate plan review proceeding for the 2017 test year filing. As discussed below in “ Retail Rate Proceedings - Filings with the LPSC (Entergy Louisiana) - Retail Rates - Electric - Formula Rate Plan Global Settlement”, a global settlement resolving the outstanding issues related to the 2017 formula rate plan filing was reached in October 2023 and approved by the LPSC in November 2023. System Energy In a filing made with the FERC in March 2018, System Energy proposed revisions to the Unit Power Sales Agreement to reflect the effects of the Tax Act. In the filing System Energy proposed to return identified quantities of unprotected excess accumulated deferred income taxes to its customers by the end of 2018. In May 2018 the FERC accepted System Energy’s proposed tax revisions with an effective date of June 1, 2018, subject to refund and the outcome of settlement and hearing procedures. Settlement discussions were terminated in April 2019, and a hearing was held in March 2020. In December 2022 the FERC issued an order requiring System Energy to compute the amount of excess accumulated deferred income taxes associated with a previously uncertain decommissioning tax position with consideration for the resolution of the tax position by the IRS. In February 2023, System Energy submitted its compliance filing. This matter was ultimately settled as a result of System Energy’s settlements with the MPSC, the APSC, the City Council, and the LPSC. See “ Complaints Against System Energy ” below for further discussion of the System Energy settlements with the MPSC, the APSC, the City Council, and the LPSC. Fuel and purchased power cost recovery The Utility operating companies are allowed to recover fuel and purchased power costs through fuel mechanisms included in electric and gas rates that are recorded as fuel cost recovery revenues. The difference between revenues collected and the current fuel and purchased power costs is generally recorded as “Deferred fuel costs” on the Utility operating companies’ financial statements. The table below shows the amount of deferred fuel costs as of December 31, 2024 and 2023 that each Utility operating company expects to recover (or return to customers) through fuel mechanisms, subject to subsequent regulatory review. 2024 2023 (In Millions) Entergy Arkansas ($45.2) ($88.3) Entergy Louisiana (a) (b) $163.4 $192.9 Entergy Mississippi ($126.3) ($130.6) Entergy New Orleans (a) (b) $8.0 $10.2 Entergy Texas ($59.3) $139.0 (a) Includes $168.1 million in both years for Entergy Louisiana and $4.1 million in both years for Entergy New Orleans of fuel, purchased power, and capacity costs, which do not currently earn a return on investment and whose recovery periods are indeterminate but are expected to be recovered over a period greater than twelve months. (b) Includes $0.7 million at Entergy Louisiana and $4.9 million at Entergy New Orleans as of December 31, 2024 of deferred fuel assets related to the respective natural gas distribution businesses classified as held for sale and included within “Current assets held for sale” on the respective consolidated balance sheets. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Entergy Arkansas Energy Cost Recovery Rider Entergy Arkansas’s retail rates include an energy cost recovery rider to recover fuel and purchased energy costs in monthly customer bills. The rider utilizes the prior calendar-year energy costs and projected energy sales for the twelve-month period commencing on April 1 of each year to develop an energy cost rate, which is redetermined annually and includes a true-up adjustment reflecting the over- or under-recovery, including carrying charges, of the energy costs for the prior calendar year. The energy cost recovery rider tariff also allows an interim rate request depending upon the level of over- or under-recovery of fuel and purchased energy costs. In January 2014, Entergy Arkansas filed a motion with the APSC relating to its upcoming energy cost rate redetermination filing that was made in March 2014. In that motion, Entergy Arkansas requested that the APSC authorize Entergy Arkansas to exclude from the redetermination of its 2014 energy cost rate $65.9 million of incremental fuel and replacement energy costs incurred in 2013 as a result of the ANO stator incident. Entergy Arkansas requested that the APSC authorize Entergy Arkansas to retain that amount in its deferred fuel balance, with recovery to be reviewed in a later period after more information was available regarding various claims associated with the ANO stator incident. In February 2014 the APSC approved Entergy Arkansas’s request to retain that amount in its deferred fuel balance. In July 2017, Entergy Arkansas filed for a change in rates pursuant to its formula rate plan rider. In that proceeding, the APSC approved a settlement agreement agreed upon by the parties, including a provision that requires Entergy Arkansas to initiate a regulatory proceeding for the purpose of recovering funds currently withheld from rates and related to the stator incident, including the $65.9 million of deferred fuel and purchased energy costs and costs related to the incremental oversight previously noted, subject to certain timelines and conditions set forth in the settlement agreement. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the incremental fuel and purchased energy expense, among other identified costs, resulting from the ANO stator incident. As a result, in third quarter 2023, Entergy Arkansas recorded a write-off of its regulatory asset for deferred fuel of $68.9 million, which includes interest, related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. See the “ ANO Damage, Outage, and NRC Reviews ” section in Note 8 to the financial statements for further discussion of the ANO stator incident and the approved motion to forgo recovery . In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh. The APSC staff filed testimony in March 2017 recommending that the redetermined rate be implemented with the first billing cycle of April 2017 under the normal operation of the tariff. Accordingly, the redetermined rate went into effect on March 31, 2017 pursuant to the tariff. In July 2017 the Arkansas Attorney General requested additional information to support certain of the costs included in Entergy Arkansas’s 2017 energy cost rate redetermination. In March 2018, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01547 per kWh to $0.01882 per kWh. The Arkansas Attorney General filed a response to Entergy Arkansas’s annual redetermination filing requesting that the APSC suspend the proposed tariff to investigate the amount of the redetermination or, alternatively, to allow recovery subject to refund. Among the reasons the Attorney General cited for suspension were questions pertaining to how Entergy Arkansas forecasted sales and potential implications of the Tax Cuts and Jobs Act. Entergy Arkansas replied to the Attorney General’s filing and stated that, to the extent there are questions pertaining to its load forecasting or the operation of the energy cost recovery rider, those issues exceed the scope of the instant rate redetermination. Entergy Arkansas also stated that potential effects of the Tax Cuts and Jobs Act are appropriately considered in the APSC’s separate proceeding regarding potential implications of the tax law. The APSC general staff filed a reply to the Attorney General’s filing and agreed that Entergy Arkansas’s filing complied with the terms of the energy cost recovery rider. The redetermined rate became effective with the first billing cycle of April 2018. Subsequently in April 2018 the APSC issued an order declining to suspend Entergy Arkansas’s energy cost recovery rider rate and declining to require further investigation at that time of the issues suggested by the Attorney General in the proceeding. Following a period of discovery, the Attorney General filed a supplemental response in October 2018 raising new issues with Entergy Arkansas’s March 2018 rate redetermination and asserting that $45.7 million of the increase should be collected subject to refund pending further investigation. Entergy Arkansas filed to dismiss the Attorney General’s supplemental response, the APSC general staff filed a motion to strike the Attorney General’s filing, and the Attorney General filed a supplemental response disputing Entergy Arkansas and the APSC staff’s filing. Applicable APSC rules and processes authorize its general staff to initiate periodic audits of Entergy Arkansas’s energy cost recovery rider. In late-2018 the APSC general staff notified Entergy Arkansas it initiated an audit of the 2017 fuel costs. The time in which the audit will be complete is uncertain at this time. In March 2022, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00959 per kWh to $0.01785 per kWh. The primary reason for the rate increase was a large under-recovered balance as a result of higher natural gas prices in 2021, particularly in the fourth quarter 2021. At the request of the APSC general staff, Entergy Arkansas deferred its request for recovery of $32 million from the under-recovery related to the February 2021 winter storms until the 2023 energy cost rate redetermination, unless a request for an interim adjustment to the energy cost recovery rider is necessary. This resulted in a redetermined rate of $0.016390 per kWh, which became effective with the first billing cycle in April 2022 through the normal operation of the tariff. In February 2023 the APSC issued orders initiating proceedings with the utilities under its jurisdiction to address the prudence of costs incurred and appropriate cost allocation of the February 2021 winter storms. With respect to any prudence review of Entergy Arkansas fuel costs, as part of the APSC’s draft report issued in its February 2021 winter storms investigation docket, the APSC included findings that the load shedding plans of the investor-owned utilities and some cooperatives were appropriate and comprehensive, and, further, that Entergy Arkansas’s emergency plan was comprehensive and had a multilayered approach supported by a system-wide response plan, which is considered an industry standard. In September 2023 the APSC issued an order in Entergy Arkansas's company-specific proceeding and found that Entergy Arkansas’s practices during the winter storms were prudent. In March 2023, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01639 per kWh to $0.01883 per kWh. The primary reason for the rate increase is a large under-recovered balance as a result of higher natural gas prices in 2022 and a $32 million deferral related to the February 2021 winter storms consistent with the APSC general staff’s request in 2022. The under-recovered balance included in the filing was partially offset by the proceeds of the $41.7 million refund that System Energy made to Entergy Arkansas in January 2023 related to the sale-leaseback renewal costs and depreciation litigation as calculated in System Energy’s January 2023 compliance report filed with the FERC. See “ Complaints Against System Energy - Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue ” below for discussion of the compliance report filed by System Energy with the FERC in January 2023. The redetermined rate of $0.01883 per kWh became effective with the first billing cycle in April 2023 through the normal operation of the tariff. In March 2024, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected a decrease in the rate from $0.01883 per kWh to $0.00882 per kWh. Due to a change in law in the State of Arkansas, the annual redetermination included $9 million, recorded as a credit to fuel expense in first quarter 2024, for recovery attributed to net metering costs in 2023. The primary reason for the rate decrease is a large over-recovered balance as a result of lower natural gas prices in 2023. To mitigate the effect of projected increases in natural gas prices in 2024, Entergy Arkansas adjusted the over-recovered balance included in the March 2024 annual redetermination filing by $43.7 million. This adjustment is expected to reduce the rate change that will be reflected in the 2025 energy cost rate redetermination. The redetermined rate of $0.00882 per kWh became effective with the first billing cycle in April 2024 through the normal operation of the tariff. Entergy Louisiana Entergy Louisiana recovers electric fuel and purchased power costs for the billing month based upon the level of such costs incurred two months prior to the billing month. Entergy Louisiana’s purchased gas adjustments include estimates for the billing month adjusted by a surcharge or credit that arises from an annual reconciliation of fuel costs incurred with fuel cost revenues billed to customers, including carrying charges. To mitigate high electric bills, primarily driven by high summer usage and elevated gas prices, Entergy Louisiana deferred approximately $225 million of fuel expense incurred in April, May, June, July, August, and September 2022 (as reflected on June, July, August, September, October, and November 2022 bills). These deferrals were included in the over/under calculation of the fuel adjustment clause, which is intended to recover the full amount of the costs included on a rolling twelve-month basis. In March 2020 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2016 through 2019. The LPSC staff issued its audit report in September 2021, and although certain internal record keeping recommendations were made, the LPSC staff did not recommend any disallowances. The next step is for the LPSC to review the report, but there is not a deadline for the review. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. Discovery is ongoing, and no audit report has been filed. In January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings.

Significant components of accumulated deferred income taxes and taxes accrued for Entergy Corporation and Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 2023 (In Thousands) Deferred tax liabilities: Plant basis differences - net ($6,451,189) ($6,192,156) Regulatory assets (1,003,045) (989,405) Nuclear decommissioning trusts/receivables (563,423) (467,267) Pension, net regulatory asset (303,007) (363,829) Combined unitary state taxes (3,600) (8,783) Power purchase agreements (89,614) (75,612) Accumulated storm damage provision — (2,474) Deferred fuel (23,305) (69,436) Other (206,648) (251,107) Total (8,643,831) (8,420,069) Deferred tax assets: Regulatory liabilities 1,394,937 1,247,530 Nuclear and other decommissioning liabilities 164,685 147,011 Pension and other post-employment benefits 22,646 116,222 Compensation 79,580 81,226 Accumulated deferred investment tax credit 52,709 55,928 Provision for allowances and contingencies 141,769 149,479 Unbilled/deferred revenues (9,960) 2,418 Net operating loss carryforwards 2,672,993 2,857,908 Capital losses and miscellaneous tax credits 111,325 107,009 Valuation allowance (338,508) (372,119) Other 212,563 220,055 Total 4,504,739 4,612,667 Non-current accrued taxes (including unrecognized tax benefits) (309,669) (422,213) Accumulated deferred income taxes and taxes accrued ($4,448,761) ($4,229,615) Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Carryover Description Carryover Amount Year(s) of expiration Federal net operating losses before 1/1/2018 $4.4 billion 2025-2037 Federal net operating losses - 1/1/2018 forward $13.9 billion N/A State net operating losses $4.3 billion 2028-2042 State net operating losses with no expiration $8.8 billion N/A Other federal and state carryforwards $134.5 million 2025-2028 Miscellaneous federal and state credits $138.8 million 2025-2044 As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes generated and reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount. Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $339 million as of December 31, 2024 and $372 million as of December 31, 2023 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. Certain accelerated tax deductions which generated taxable losses in various taxing jurisdictions, and which have a limited term carryover period, have resulted in the impairment of the realizability of such carryovers and are reflected in the valuation allowance disclosed above. Significant components of accumulated deferred income taxes and taxes accrued for the Registrant Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,530,196) ($2,729,299) ($849,623) ($272,182) ($727,242) ($466,361) Regulatory assets (219,773) (497,177) (37,374) (72,389) (100,959) (75,606) Nuclear decommissioning trusts/receivables (185,725) (202,364) — — — (175,341) Pension, net regulatory asset (101,887) (84,732) (26,064) (9,687) (16,569) — Power purchase agreements 11,993 (97,846) 1,140 (12,385) (5,148) — Deferred fuel — (4,785) (17,234) (1,247) — (78) Other (24,430) (106,590) (5,231) (5,133) (4,512) (13,572) Total (2,050,018) (3,722,793) (934,386) (373,023) (854,430) (730,958) Deferred tax assets: Regulatory liabilities 310,621 678,086 53,046 89,385 37,325 229,065 Nuclear and other decommissioning liabilities 127,933 18,649 — (407) 97 17,956 Pension and other post-employment benefits (29,923) 39,379 (8,989) (19,443) (23,403) (24,642) Compensation 4,851 7,119 3,277 1,394 2,596 515 Accumulated deferred investment tax credit 6,360 26,549 3,355 4,205 1,515 10,724 Provision for allowances and contingencies 31,686 59,448 11,361 23,998 4,358 225 Unbilled/deferred revenues 3,546 (24,017) 1,274 715 7,925 — Net operating loss carryforwards 126,255 336,128 305 30,740 50 69,611 Capital losses and miscellaneous tax credits 14,489 17,029 8,206 16,220 1,273 10,788 Other 11,608 54,207 1,096 1,692 1,189 — Total 607,426 1,212,577 72,931 148,499 32,925 314,242 Non-current accrued taxes (including unrecognized tax benefits) (46,577) 32,262 (8,661) 22,983 (47,344) (35,114) Accumulated deferred income taxes and taxes accrued ($1,489,169) ($2,477,954) ($870,116) ($201,541) ($868,849) ($451,830) 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,421,272) ($2,639,079) ($810,120) ($272,187) ($671,072) ($450,559) Regulatory assets (241,427) (500,395) (41,519) (23,618) (104,562) (76,522) Nuclear decommissioning trusts/receivables (154,106) (173,402) — — — (139,858) Pension, net regulatory asset (96,853) (82,305) (24,342) (9,216) (17,522) (18,895) Power purchase agreements 15,993 (112,292) 1,140 (12,516) (4,551) — Accumulated storm damage provision — — — — (1,387) — Deferred fuel — (17,065) (21,137) (1,563) (29,194) (37) Other (21,187) (126,952) (6,844) (4,270) (3,301) (9,051) Total (1,918,852) (3,651,490) (902,822) (323,370) (831,589) (694,922) Deferred tax assets: Regulatory liabilities 296,278 575,459 54,586 42,921 41,137 240,310 Nuclear and other decommissioning liabilities 118,301 9,055 — — 97 19,259 Pension and other post-employment benefits (28,868) 46,837 (10,064) (19,354) (21,977) (2,641) Compensation 4,054 6,078 3,649 1,268 2,181 406 Accumulated deferred investment tax credit 6,761 27,902 3,446 4,431 1,672 11,717 Provision for allowances and contingencies 23,956 70,297 10,072 25,846 8,659 225 Unbilled/deferred revenues 5,962 (20,375) 6,194 1,045 8,365 — Net operating loss carryforwards 94,321 459,553 8,375 26,227 61 35,089 Capital losses and miscellaneous tax credits 7,137 13,073 7,613 15,684 1,655 13,211 Other 17,072 52,438 1,556 (235) 1,740 — Total 544,974 1,240,317 85,427 97,833 43,590 317,576 Non-current accrued taxes (including unrecognized tax benefits) (63,175) 19,731 (4,349) 29,922 (26,906) (28,398) Accumulated deferred income taxes and taxes accrued ($1,437,053) ($2,391,442) ($821,744) ($195,615) ($814,905) ($405,744) The Registrant Subsidiaries’ estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy Federal net operating losses before 1/1/2018 $— million $812.8 million $— million $82.6 million $— million $— million Year(s) of expiration N/A 2035-2037 N/A 2037 N/A N/A Federal net operating losses - 1/1/2018 forward $576 million $2.6 billion $— million $26.4 million $1.5 billion $264.7 million Year(s) of expiration N/A N/A N/A N/A N/A N/A State net operating losses $597.4 million $5.8 billion $7.1 million $336.6 million $1 million $370.1 million Year(s) of expiration 2028-2032 N/A 2039-2042 N/A 2028 2040-2044 Misc. federal credits $12.9 million $21 million $4.9 million $16.7 million $0.8 million $5.7 million Year(s) of expiration 2038-2044 2035-2044 2038-2044 2037-2044 2039-2044 2029-2044 State credits $— million $1.1 million $8.3 million $— million $1.3 million $17 million Year(s) of expiration N/A N/A 2025-2028 N/A 2027-2033 2025-2028 Unrecognized tax benefits Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements. If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded. A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows: 2024 2023 2022 (In Thousands) Gross balance at January 1 $2,439,910 $6,393,599 $5,759,968 Additions based on tax positions related to the current year 12,731 332,884 792,134 Additions for tax positions of prior years 21,149 194,894 37,259 Reductions for tax positions of prior years (a) (85,715) (1,300,381) (195,762) Settlements (a) (33,208) (3,181,086) — Gross balance at December 31 2,354,867 2,439,910 6,393,599 Offsets to gross unrecognized tax benefits: Loss and tax credit carryovers (2,079,778) (2,160,484) (5,566,212) Cash paid to taxing authorities (27,000) — (82,000) Unrecognized tax benefits net of unused tax attributes and payments (b) $248,089 $279,426 $745,387 (a) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. Amounts in 2024 are primarily related to the resolution of 2014-2018 Arkansas tax examination as discussed in “ Income Tax Audits - State Income Tax Audits ” below. (b) Potential tax liability above what is payable on tax returns. The balances of unrecognized tax benefits include $1,900 million, $1,899 million, and $3,254 million as of December 31, 2024, 2023, and 2022, respectively, which, if recognized, would lower the effective income tax rates. Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $455 million, $541 million, and $3,140 million as of December 31, 2024, 2023, and 2022, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense. Entergy’s December 31, 2024, 2023, and 2022 accrued balance for the possible payment of interest is approximately $32 million, $39 million, and $50 million, respectively. Interest (net-of-tax) of ($7) million, ($11) million, and $8 million was recorded in 2024, 2023, and 2022, respectively.

(b) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. The Registrant Subsidiaries’ balances of unrecognized tax benefits included amounts which, if recognized, would have reduced income tax expense as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $32.6 $57.2 $377.9 Entergy Louisiana $868.2 $862.5 $720.8 Entergy Mississippi $1.3 $1.0 $151.2 Entergy New Orleans $18.3 $18.2 $310.7 Entergy Texas $50.3 $2.9 $3.3 System Energy $4.0 $3.1 $2.5 Accrued balances for the possible payment of interest related to unrecognized tax benefits for the Registrant Subsidiaries are as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $8.4 $7.8 $4.3 Entergy Louisiana $5.1 $1.5 $4.1 Entergy Mississippi $3.2 $2.1 $3.1 Entergy New Orleans $0.6 $0.6 $6.4 Entergy Texas $0.5 $— $1.1 System Energy $2.9 $1.9 $1.9 The Registrant Subsidiaries record interest and penalties related to unrecognized tax benefits in income tax expense. No penalties were recorded in 2024, 2023, and 2022. Interest (net-of-tax) was recorded as follows: 2024 2023 2022 (In Millions) Entergy Arkansas $0.6 $3.5 $1.6 Entergy Louisiana $3.6 ($2.6) $0.4 Entergy Mississippi $1.1 ($1.0) $0.7 Entergy New Orleans $— ($5.8) $1.2 Entergy Texas $0.5 ($1.1) $— System Energy $1.0 $— ($10.2) Income Tax Audits Entergy and its subsidiaries file U.S. federal and various state income tax returns. IRS examinations are complete for years before 2019. All state taxing authorities’ examinations are complete for years before 2016. Entergy regularly defends its positions and works with the IRS to resolve audits. The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months. 2016-2018 IRS Audit The IRS completed its examination of the 2016 through 2018 tax years and issued a Revenue Agent Report (RAR) for each federal filer under audit in November 2023. Entergy agreed to all adjustments contained in the RARs. Entergy and the Registrant Subsidiaries recorded all the material effects resulting from the RARs in the fourth quarter of 2023. Utility Restructurings In 2017, Entergy New Orleans undertook an internal restructuring, and in 2018, Entergy Arkansas and Entergy Mississippi also participated in internal restructurings under which these three Utility operating companies joined Entergy Louisiana as wholly-owned subsidiaries of Entergy Utility Holding Company, LLC. The change in ownership required Entergy to recognize Entergy Arkansas’s nuclear decommissioning liabilities for income tax purposes, which resulted in recognition of a gain for income tax purposes and a corresponding increase in the tax basis of assets, in accordance with the Internal Revenue Code and Treasury Regulations. Entergy determined that there was uncertainty regarding the treatment of certain aspects of the restructurings and recorded provisions for uncertain tax positions which are now considered to be effectively settled in accordance with accounting standards. The reversal of such provisions for uncertain tax positions results in a reduction of income tax expense of $156 million for Entergy Arkansas, $1 million for Entergy Mississippi, and $6 million for Entergy New Orleans. The IRS also required Entergy New Orleans to reverse a tax gain associated with the 2017 restructuring that had been previously recognized, allowing Entergy New Orleans to reduce its tax expense by $39 million. After the restructuring, Entergy Arkansas adopted a new method of accounting for income tax purposes in which its nuclear decommissioning costs are treated as production costs of electricity includable in cost of goods sold, which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return that was treated as an unrecognized tax benefit. In conjunction with the audit, Entergy agreed with the IRS adjustments concerning the nuclear decommissioning tax position allowing Entergy Arkansas to include $102 million of its decommissioning liability in cost of goods sold. Mark-to-Market Method of Accounting In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement as well as other intercompany power purchase agreements. The election resulted in a $2 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with the Vidalia contract and various other third-party and intercompany wholesale electric power purchase and sale agreements. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $132 million and a corresponding reduction of income tax expense. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for the Unit Power Sales Agreement and various intercompany wholesale electric contracts which resulted in a $1 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $139 million and a corresponding reduction of income tax expense. In 2018, Entergy Arkansas and Entergy Mississippi each accrued approximately $2 billion in deductible temporary differences related to mark-to-market tax accounting for the Unit Power Sales Agreement and various wholesale electric contracts. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The effective settlement of the mark-to-market tax position for Entergy Arkansas resulted in the accrual of an increase to tax expense of $40 million, which was offset by approximately $5 million of miscellaneous excess ADIT recognized as a result of the 2016-2018 IRS audit resolution. The net increase to tax expense is deferred as a regulatory asset, as discussed within the “ Regulatory and Other Matters ” section below. Restructuring of Entergy’s Non-Utility Operations Business During the 2016 to 2018 audit period, the ownership of certain of Entergy’s non-utility operations business nuclear power plants (previously reported as part of Entergy Wholesale Commodities) was restructured. Such restructuring transactions required Entergy to recognize the plants’ nuclear decommissioning liabilities for income tax purposes. The accrual of the nuclear decommissioning liabilities also required Entergy to recognize a gain for income tax purposes, a significant portion of which resulted in an increase in the tax basis of the assets. Because certain aspects of the restructuring transactions involved uncertainty, Entergy recorded a provision for uncertain tax positions. The IRS did not propose adjustments to the tax treatment of the restructuring transactions resulting in a net decrease to income tax expense of $288 million from the reversal of the provision for uncertain tax positions in fourth quarter 2023. Reduction of Net Operating Loss Carryovers The IRS audit reduced Entergy’s net operating loss carryover by $8 billion. A portion of Entergy’s audit adjustments were not offset by losses which resulted in a tax liability of $79 million, which was fully offset by prior deposits made by Entergy. Entergy received an assessment of interest in excess of prior deposits of $13 million in December 2023, and such interest was paid in January 2024. Net operating loss carryovers were reduced by $4 billion for Entergy Arkansas, $1 billion for Entergy Louisiana, $2 billion for Entergy Mississippi, $1 billion for Entergy New Orleans, and $40 million for System Energy. The IRS audit adjustments were also factored into the settle-up required under Entergy’s intercompany income tax allocation agreement, and such amounts were settled in the fourth quarter of 2023. Regulatory and Other Matters In accordance with prior regulatory agreements associated with the Entergy Louisiana and Entergy Gulf States Louisiana business combination and Entergy New Orleans restructuring and general rate-making principles, Entergy Louisiana and Entergy New Orleans, respectively, recorded a regulatory liabilit

Significant components of accumulated deferred income taxes and taxes accrued for Entergy Corporation and Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 2023 (In Thousands) Deferred tax liabilities: Plant basis differences - net ($6,451,189) ($6,192,156) Regulatory assets (1,003,045) (989,405) Nuclear decommissioning trusts/receivables (563,423) (467,267) Pension, net regulatory asset (303,007) (363,829) Combined unitary state taxes (3,600) (8,783) Power purchase agreements (89,614) (75,612) Accumulated storm damage provision — (2,474) Deferred fuel (23,305) (69,436) Other (206,648) (251,107) Total (8,643,831) (8,420,069) Deferred tax assets: Regulatory liabilities 1,394,937 1,247,530 Nuclear and other decommissioning liabilities 164,685 147,011 Pension and other post-employment benefits 22,646 116,222 Compensation 79,580 81,226 Accumulated deferred investment tax credit 52,709 55,928 Provision for allowances and contingencies 141,769 149,479 Unbilled/deferred revenues (9,960) 2,418 Net operating loss carryforwards 2,672,993 2,857,908 Capital losses and miscellaneous tax credits 111,325 107,009 Valuation allowance (338,508) (372,119) Other 212,563 220,055 Total 4,504,739 4,612,667 Non-current accrued taxes (including unrecognized tax benefits) (309,669) (422,213) Accumulated deferred income taxes and taxes accrued ($4,448,761) ($4,229,615) Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Carryover Description Carryover Amount Year(s) of expiration Federal net operating losses before 1/1/2018 $4.4 billion 2025-2037 Federal net operating losses - 1/1/2018 forward $13.9 billion N/A State net operating losses $4.3 billion 2028-2042 State net operating losses with no expiration $8.8 billion N/A Other federal and state carryforwards $134.5 million 2025-2028 Miscellaneous federal and state credits $138.8 million 2025-2044 As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes generated and reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount. Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $339 million as of December 31, 2024 and $372 million as of December 31, 2023 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. Certain accelerated tax deductions which generated taxable losses in various taxing jurisdictions, and which have a limited term carryover period, have resulted in the impairment of the realizability of such carryovers and are reflected in the valuation allowance disclosed above. Significant components of accumulated deferred income taxes and taxes accrued for the Registrant Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,530,196) ($2,729,299) ($849,623) ($272,182) ($727,242) ($466,361) Regulatory assets (219,773) (497,177) (37,374) (72,389) (100,959) (75,606) Nuclear decommissioning trusts/receivables (185,725) (202,364) — — — (175,341) Pension, net regulatory asset (101,887) (84,732) (26,064) (9,687) (16,569) — Power purchase agreements 11,993 (97,846) 1,140 (12,385) (5,148) — Deferred fuel — (4,785) (17,234) (1,247) — (78) Other (24,430) (106,590) (5,231) (5,133) (4,512) (13,572) Total (2,050,018) (3,722,793) (934,386) (373,023) (854,430) (730,958) Deferred tax assets: Regulatory liabilities 310,621 678,086 53,046 89,385 37,325 229,065 Nuclear and other decommissioning liabilities 127,933 18,649 — (407) 97 17,956 Pension and other post-employment benefits (29,923) 39,379 (8,989) (19,443) (23,403) (24,642) Compensation 4,851 7,119 3,277 1,394 2,596 515 Accumulated deferred investment tax credit 6,360 26,549 3,355 4,205 1,515 10,724 Provision for allowances and contingencies 31,686 59,448 11,361 23,998 4,358 225 Unbilled/deferred revenues 3,546 (24,017) 1,274 715 7,925 — Net operating loss carryforwards 126,255 336,128 305 30,740 50 69,611 Capital losses and miscellaneous tax credits 14,489 17,029 8,206 16,220 1,273 10,788 Other 11,608 54,207 1,096 1,692 1,189 — Total 607,426 1,212,577 72,931 148,499 32,925 314,242 Non-current accrued taxes (including unrecognized tax benefits) (46,577) 32,262 (8,661) 22,983 (47,344) (35,114) Accumulated deferred income taxes and taxes accrued ($1,489,169) ($2,477,954) ($870,116) ($201,541) ($868,849) ($451,830) 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,421,272) ($2,639,079) ($810,120) ($272,187) ($671,072) ($450,559) Regulatory assets (241,427) (500,395) (41,519) (23,618) (104,562) (76,522) Nuclear decommissioning trusts/receivables (154,106) (173,402) — — — (139,858) Pension, net regulatory asset (96,853) (82,305) (24,342) (9,216) (17,522) (18,895) Power purchase agreements 15,993 (112,292) 1,140 (12,516) (4,551) — Accumulated storm damage provision — — — — (1,387) — Deferred fuel — (17,065) (21,137) (1,563) (29,194) (37) Other (21,187) (126,952) (6,844) (4,270) (3,301) (9,051) Total (1,918,852) (3,651,490) (902,822) (323,370) (831,589) (694,922) Deferred tax assets: Regulatory liabilities 296,278 575,459 54,586 42,921 41,137 240,310 Nuclear and other decommissioning liabilities 118,301 9,055 — — 97 19,259 Pension and other post-employment benefits (28,868) 46,837 (10,064) (19,354) (21,977) (2,641) Compensation 4,054 6,078 3,649 1,268 2,181 406 Accumulated deferred investment tax credit 6,761 27,902 3,446 4,431 1,672 11,717 Provision for allowances and contingencies 23,956 70,297 10,072 25,846 8,659 225 Unbilled/deferred revenues 5,962 (20,375) 6,194 1,045 8,365 — Net operating loss carryforwards 94,321 459,553 8,375 26,227 61 35,089 Capital losses and miscellaneous tax credits 7,137 13,073 7,613 15,684 1,655 13,211 Other 17,072 52,438 1,556 (235) 1,740 — Total 544,974 1,240,317 85,427 97,833 43,590 317,576 Non-current accrued taxes (including unrecognized tax benefits) (63,175) 19,731 (4,349) 29,922 (26,906) (28,398) Accumulated deferred income taxes and taxes accrued ($1,437,053) ($2,391,442) ($821,744) ($195,615) ($814,905) ($405,744) The Registrant Subsidiaries’ estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy Federal net operating losses before 1/1/2018 $— million $812.8 million $— million $82.6 million $— million $— million Year(s) of expiration N/A 2035-2037 N/A 2037 N/A N/A Federal net operating losses - 1/1/2018 forward $576 million $2.6 billion $— million $26.4 million $1.5 billion $264.7 million Year(s) of expiration N/A N/A N/A N/A N/A N/A State net operating losses $597.4 million $5.8 billion $7.1 million $336.6 million $1 million $370.1 million Year(s) of expiration 2028-2032 N/A 2039-2042 N/A 2028 2040-2044 Misc. federal credits $12.9 million $21 million $4.9 million $16.7 million $0.8 million $5.7 million Year(s) of expiration 2038-2044 2035-2044 2038-2044 2037-2044 2039-2044 2029-2044 State credits $— million $1.1 million $8.3 million $— million $1.3 million $17 million Year(s) of expiration N/A N/A 2025-2028 N/A 2027-2033 2025-2028 Unrecognized tax benefits Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements. If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded. A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows: 2024 2023 2022 (In Thousands) Gross balance at January 1 $2,439,910 $6,393,599 $5,759,968 Additions based on tax positions related to the current year 12,731 332,884 792,134 Additions for tax positions of prior years 21,149 194,894 37,259 Reductions for tax positions of prior years (a) (85,715) (1,300,381) (195,762) Settlements (a) (33,208) (3,181,086) — Gross balance at December 31 2,354,867 2,439,910 6,393,599 Offsets to gross unrecognized tax benefits: Loss and tax credit carryovers (2,079,778) (2,160,484) (5,566,212) Cash paid to taxing authorities (27,000) — (82,000) Unrecognized tax benefits net of unused tax attributes and payments (b) $248,089 $279,426 $745,387 (a) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. Amounts in 2024 are primarily related to the resolution of 2014-2018 Arkansas tax examination as discussed in “ Income Tax Audits - State Income Tax Audits ” below. (b) Potential tax liability above what is payable on tax returns. The balances of unrecognized tax benefits include $1,900 million, $1,899 million, and $3,254 million as of December 31, 2024, 2023, and 2022, respectively, which, if recognized, would lower the effective income tax rates. Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $455 million, $541 million, and $3,140 million as of December 31, 2024, 2023, and 2022, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense. Entergy’s December 31, 2024, 2023, and 2022 accrued balance for the possible payment of interest is approximately $32 million, $39 million, and $50 million, respectively. Interest (net-of-tax) of ($7) million, ($11) million, and $8 million was recorded in 2024, 2023, and 2022, respectively.

(b) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. The Registrant Subsidiaries’ balances of unrecognized tax benefits included amounts which, if recognized, would have reduced income tax expense as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $32.6 $57.2 $377.9 Entergy Louisiana $868.2 $862.5 $720.8 Entergy Mississippi $1.3 $1.0 $151.2 Entergy New Orleans $18.3 $18.2 $310.7 Entergy Texas $50.3 $2.9 $3.3 System Energy $4.0 $3.1 $2.5 Accrued balances for the possible payment of interest related to unrecognized tax benefits for the Registrant Subsidiaries are as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $8.4 $7.8 $4.3 Entergy Louisiana $5.1 $1.5 $4.1 Entergy Mississippi $3.2 $2.1 $3.1 Entergy New Orleans $0.6 $0.6 $6.4 Entergy Texas $0.5 $— $1.1 System Energy $2.9 $1.9 $1.9 The Registrant Subsidiaries record interest and penalties related to unrecognized tax benefits in income tax expense. No penalties were recorded in 2024, 2023, and 2022. Interest (net-of-tax) was recorded as follows: 2024 2023 2022 (In Millions) Entergy Arkansas $0.6 $3.5 $1.6 Entergy Louisiana $3.6 ($2.6) $0.4 Entergy Mississippi $1.1 ($1.0) $0.7 Entergy New Orleans $— ($5.8) $1.2 Entergy Texas $0.5 ($1.1) $— System Energy $1.0 $— ($10.2) Income Tax Audits Entergy and its subsidiaries file U.S. federal and various state income tax returns. IRS examinations are complete for years before 2019. All state taxing authorities’ examinations are complete for years before 2016. Entergy regularly defends its positions and works with the IRS to resolve audits. The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months. 2016-2018 IRS Audit The IRS completed its examination of the 2016 through 2018 tax years and issued a Revenue Agent Report (RAR) for each federal filer under audit in November 2023. Entergy agreed to all adjustments contained in the RARs. Entergy and the Registrant Subsidiaries recorded all the material effects resulting from the RARs in the fourth quarter of 2023. Utility Restructurings In 2017, Entergy New Orleans undertook an internal restructuring, and in 2018, Entergy Arkansas and Entergy Mississippi also participated in internal restructurings under which these three Utility operating companies joined Entergy Louisiana as wholly-owned subsidiaries of Entergy Utility Holding Company, LLC. The change in ownership required Entergy to recognize Entergy Arkansas’s nuclear decommissioning liabilities for income tax purposes, which resulted in recognition of a gain for income tax purposes and a corresponding increase in the tax basis of assets, in accordance with the Internal Revenue Code and Treasury Regulations. Entergy determined that there was uncertainty regarding the treatment of certain aspects of the restructurings and recorded provisions for uncertain tax positions which are now considered to be effectively settled in accordance with accounting standards. The reversal of such provisions for uncertain tax positions results in a reduction of income tax expense of $156 million for Entergy Arkansas, $1 million for Entergy Mississippi, and $6 million for Entergy New Orleans. The IRS also required Entergy New Orleans to reverse a tax gain associated with the 2017 restructuring that had been previously recognized, allowing Entergy New Orleans to reduce its tax expense by $39 million. After the restructuring, Entergy Arkansas adopted a new method of accounting for income tax purposes in which its nuclear decommissioning costs are treated as production costs of electricity includable in cost of goods sold, which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return that was treated as an unrecognized tax benefit. In conjunction with the audit, Entergy agreed with the IRS adjustments concerning the nuclear decommissioning tax position allowing Entergy Arkansas to include $102 million of its decommissioning liability in cost of goods sold. Mark-to-Market Method of Accounting In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement as well as other intercompany power purchase agreements. The election resulted in a $2 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with the Vidalia contract and various other third-party and intercompany wholesale electric power purchase and sale agreements. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $132 million and a corresponding reduction of income tax expense. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for the Unit Power Sales Agreement and various intercompany wholesale electric contracts which resulted in a $1 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $139 million and a corresponding reduction of income tax expense. In 2018, Entergy Arkansas and Entergy Mississippi each accrued approximately $2 billion in deductible temporary differences related to mark-to-market tax accounting for the Unit Power Sales Agreement and various wholesale electric contracts. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The effective settlement of the mark-to-market tax position for Entergy Arkansas resulted in the accrual of an increase to tax expense of $40 million, which was offset by approximately $5 million of miscellaneous excess ADIT recognized as a result of the 2016-2018 IRS audit resolution. The net increase to tax expense is deferred as a regulatory asset, as discussed within the “ Regulatory and Other Matters ” section below. Restructuring of Entergy’s Non-Utility Operations Business During the 2016 to 2018 audit period, the ownership of certain of Entergy’s non-utility operations business nuclear power plants (previously reported as part of Entergy Wholesale Commodities) was restructured. Such restructuring transactions required Entergy to recognize the plants’ nuclear decommissioning liabilities for income tax purposes. The accrual of the nuclear decommissioning liabilities also required Entergy to recognize a gain for income tax purposes, a significant portion of which resulted in an increase in the tax basis of the assets. Because certain aspects of the restructuring transactions involved uncertainty, Entergy recorded a provision for uncertain tax positions. The IRS did not propose adjustments to the tax treatment of the restructuring transactions resulting in a net decrease to income tax expense of $288 million from the reversal of the provision for uncertain tax positions in fourth quarter 2023. Reduction of Net Operating Loss Carryovers The IRS audit reduced Entergy’s net operating loss carryover by $8 billion. A portion of Entergy’s audit adjustments were not offset by losses which resulted in a tax liability of $79 million, which was fully offset by prior deposits made by Entergy. Entergy received an assessment of interest in excess of prior deposits of $13 million in December 2023, and such interest was paid in January 2024. Net operating loss carryovers were reduced by $4 billion for Entergy Arkansas, $1 billion for Entergy Louisiana, $2 billion for Entergy Mississippi, $1 billion for Entergy New Orleans, and $40 million for System Energy. The IRS audit adjustments were also factored into the settle-up required under Entergy’s intercompany income tax allocation agreement, and such amounts were settled in the fourth quarter of 2023. Regulatory and Other Matters In accordance with prior regulatory agreements associated with the Entergy Louisiana and Entergy Gulf States Louisiana business combination and Entergy New Orleans restructuring and general rate-making principles, Entergy Louisiana and Entergy New Orleans, respectively, recorded a regulatory liabilit

Significant components of accumulated deferred income taxes and taxes accrued for Entergy Corporation and Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 2023 (In Thousands) Deferred tax liabilities: Plant basis differences - net ($6,451,189) ($6,192,156) Regulatory assets (1,003,045) (989,405) Nuclear decommissioning trusts/receivables (563,423) (467,267) Pension, net regulatory asset (303,007) (363,829) Combined unitary state taxes (3,600) (8,783) Power purchase agreements (89,614) (75,612) Accumulated storm damage provision — (2,474) Deferred fuel (23,305) (69,436) Other (206,648) (251,107) Total (8,643,831) (8,420,069) Deferred tax assets: Regulatory liabilities 1,394,937 1,247,530 Nuclear and other decommissioning liabilities 164,685 147,011 Pension and other post-employment benefits 22,646 116,222 Compensation 79,580 81,226 Accumulated deferred investment tax credit 52,709 55,928 Provision for allowances and contingencies 141,769 149,479 Unbilled/deferred revenues (9,960) 2,418 Net operating loss carryforwards 2,672,993 2,857,908 Capital losses and miscellaneous tax credits 111,325 107,009 Valuation allowance (338,508) (372,119) Other 212,563 220,055 Total 4,504,739 4,612,667 Non-current accrued taxes (including unrecognized tax benefits) (309,669) (422,213) Accumulated deferred income taxes and taxes accrued ($4,448,761) ($4,229,615) Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Carryover Description Carryover Amount Year(s) of expiration Federal net operating losses before 1/1/2018 $4.4 billion 2025-2037 Federal net operating losses - 1/1/2018 forward $13.9 billion N/A State net operating losses $4.3 billion 2028-2042 State net operating losses with no expiration $8.8 billion N/A Other federal and state carryforwards $134.5 million 2025-2028 Miscellaneous federal and state credits $138.8 million 2025-2044 As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes generated and reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount. Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $339 million as of December 31, 2024 and $372 million as of December 31, 2023 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. Certain accelerated tax deductions which generated taxable losses in various taxing jurisdictions, and which have a limited term carryover period, have resulted in the impairment of the realizability of such carryovers and are reflected in the valuation allowance disclosed above. Significant components of accumulated deferred income taxes and taxes accrued for the Registrant Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,530,196) ($2,729,299) ($849,623) ($272,182) ($727,242) ($466,361) Regulatory assets (219,773) (497,177) (37,374) (72,389) (100,959) (75,606) Nuclear decommissioning trusts/receivables (185,725) (202,364) — — — (175,341) Pension, net regulatory asset (101,887) (84,732) (26,064) (9,687) (16,569) — Power purchase agreements 11,993 (97,846) 1,140 (12,385) (5,148) — Deferred fuel — (4,785) (17,234) (1,247) — (78) Other (24,430) (106,590) (5,231) (5,133) (4,512) (13,572) Total (2,050,018) (3,722,793) (934,386) (373,023) (854,430) (730,958) Deferred tax assets: Regulatory liabilities 310,621 678,086 53,046 89,385 37,325 229,065 Nuclear and other decommissioning liabilities 127,933 18,649 — (407) 97 17,956 Pension and other post-employment benefits (29,923) 39,379 (8,989) (19,443) (23,403) (24,642) Compensation 4,851 7,119 3,277 1,394 2,596 515 Accumulated deferred investment tax credit 6,360 26,549 3,355 4,205 1,515 10,724 Provision for allowances and contingencies 31,686 59,448 11,361 23,998 4,358 225 Unbilled/deferred revenues 3,546 (24,017) 1,274 715 7,925 — Net operating loss carryforwards 126,255 336,128 305 30,740 50 69,611 Capital losses and miscellaneous tax credits 14,489 17,029 8,206 16,220 1,273 10,788 Other 11,608 54,207 1,096 1,692 1,189 — Total 607,426 1,212,577 72,931 148,499 32,925 314,242 Non-current accrued taxes (including unrecognized tax benefits) (46,577) 32,262 (8,661) 22,983 (47,344) (35,114) Accumulated deferred income taxes and taxes accrued ($1,489,169) ($2,477,954) ($870,116) ($201,541) ($868,849) ($451,830) 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,421,272) ($2,639,079) ($810,120) ($272,187) ($671,072) ($450,559) Regulatory assets (241,427) (500,395) (41,519) (23,618) (104,562) (76,522) Nuclear decommissioning trusts/receivables (154,106) (173,402) — — — (139,858) Pension, net regulatory asset (96,853) (82,305) (24,342) (9,216) (17,522) (18,895) Power purchase agreements 15,993 (112,292) 1,140 (12,516) (4,551) — Accumulated storm damage provision — — — — (1,387) — Deferred fuel — (17,065) (21,137) (1,563) (29,194) (37) Other (21,187) (126,952) (6,844) (4,270) (3,301) (9,051) Total (1,918,852) (3,651,490) (902,822) (323,370) (831,589) (694,922) Deferred tax assets: Regulatory liabilities 296,278 575,459 54,586 42,921 41,137 240,310 Nuclear and other decommissioning liabilities 118,301 9,055 — — 97 19,259 Pension and other post-employment benefits (28,868) 46,837 (10,064) (19,354) (21,977) (2,641) Compensation 4,054 6,078 3,649 1,268 2,181 406 Accumulated deferred investment tax credit 6,761 27,902 3,446 4,431 1,672 11,717 Provision for allowances and contingencies 23,956 70,297 10,072 25,846 8,659 225 Unbilled/deferred revenues 5,962 (20,375) 6,194 1,045 8,365 — Net operating loss carryforwards 94,321 459,553 8,375 26,227 61 35,089 Capital losses and miscellaneous tax credits 7,137 13,073 7,613 15,684 1,655 13,211 Other 17,072 52,438 1,556 (235) 1,740 — Total 544,974 1,240,317 85,427 97,833 43,590 317,576 Non-current accrued taxes (including unrecognized tax benefits) (63,175) 19,731 (4,349) 29,922 (26,906) (28,398) Accumulated deferred income taxes and taxes accrued ($1,437,053) ($2,391,442) ($821,744) ($195,615) ($814,905) ($405,744) The Registrant Subsidiaries’ estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy Federal net operating losses before 1/1/2018 $— million $812.8 million $— million $82.6 million $— million $— million Year(s) of expiration N/A 2035-2037 N/A 2037 N/A N/A Federal net operating losses - 1/1/2018 forward $576 million $2.6 billion $— million $26.4 million $1.5 billion $264.7 million Year(s) of expiration N/A N/A N/A N/A N/A N/A State net operating losses $597.4 million $5.8 billion $7.1 million $336.6 million $1 million $370.1 million Year(s) of expiration 2028-2032 N/A 2039-2042 N/A 2028 2040-2044 Misc. federal credits $12.9 million $21 million $4.9 million $16.7 million $0.8 million $5.7 million Year(s) of expiration 2038-2044 2035-2044 2038-2044 2037-2044 2039-2044 2029-2044 State credits $— million $1.1 million $8.3 million $— million $1.3 million $17 million Year(s) of expiration N/A N/A 2025-2028 N/A 2027-2033 2025-2028 Unrecognized tax benefits Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements. If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded. A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows: 2024 2023 2022 (In Thousands) Gross balance at January 1 $2,439,910 $6,393,599 $5,759,968 Additions based on tax positions related to the current year 12,731 332,884 792,134 Additions for tax positions of prior years 21,149 194,894 37,259 Reductions for tax positions of prior years (a) (85,715) (1,300,381) (195,762) Settlements (a) (33,208) (3,181,086) — Gross balance at December 31 2,354,867 2,439,910 6,393,599 Offsets to gross unrecognized tax benefits: Loss and tax credit carryovers (2,079,778) (2,160,484) (5,566,212) Cash paid to taxing authorities (27,000) — (82,000) Unrecognized tax benefits net of unused tax attributes and payments (b) $248,089 $279,426 $745,387 (a) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. Amounts in 2024 are primarily related to the resolution of 2014-2018 Arkansas tax examination as discussed in “ Income Tax Audits - State Income Tax Audits ” below. (b) Potential tax liability above what is payable on tax returns. The balances of unrecognized tax benefits include $1,900 million, $1,899 million, and $3,254 million as of December 31, 2024, 2023, and 2022, respectively, which, if recognized, would lower the effective income tax rates. Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $455 million, $541 million, and $3,140 million as of December 31, 2024, 2023, and 2022, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense. Entergy’s December 31, 2024, 2023, and 2022 accrued balance for the possible payment of interest is approximately $32 million, $39 million, and $50 million, respectively. Interest (net-of-tax) of ($7) million, ($11) million, and $8 million was recorded in 2024, 2023, and 2022, respectively.

(b) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. The Registrant Subsidiaries’ balances of unrecognized tax benefits included amounts which, if recognized, would have reduced income tax expense as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $32.6 $57.2 $377.9 Entergy Louisiana $868.2 $862.5 $720.8 Entergy Mississippi $1.3 $1.0 $151.2 Entergy New Orleans $18.3 $18.2 $310.7 Entergy Texas $50.3 $2.9 $3.3 System Energy $4.0 $3.1 $2.5 Accrued balances for the possible payment of interest related to unrecognized tax benefits for the Registrant Subsidiaries are as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $8.4 $7.8 $4.3 Entergy Louisiana $5.1 $1.5 $4.1 Entergy Mississippi $3.2 $2.1 $3.1 Entergy New Orleans $0.6 $0.6 $6.4 Entergy Texas $0.5 $— $1.1 System Energy $2.9 $1.9 $1.9 The Registrant Subsidiaries record interest and penalties related to unrecognized tax benefits in income tax expense. No penalties were recorded in 2024, 2023, and 2022. Interest (net-of-tax) was recorded as follows: 2024 2023 2022 (In Millions) Entergy Arkansas $0.6 $3.5 $1.6 Entergy Louisiana $3.6 ($2.6) $0.4 Entergy Mississippi $1.1 ($1.0) $0.7 Entergy New Orleans $— ($5.8) $1.2 Entergy Texas $0.5 ($1.1) $— System Energy $1.0 $— ($10.2) Income Tax Audits Entergy and its subsidiaries file U.S. federal and various state income tax returns. IRS examinations are complete for years before 2019. All state taxing authorities’ examinations are complete for years before 2016. Entergy regularly defends its positions and works with the IRS to resolve audits. The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months. 2016-2018 IRS Audit The IRS completed its examination of the 2016 through 2018 tax years and issued a Revenue Agent Report (RAR) for each federal filer under audit in November 2023. Entergy agreed to all adjustments contained in the RARs. Entergy and the Registrant Subsidiaries recorded all the material effects resulting from the RARs in the fourth quarter of 2023. Utility Restructurings In 2017, Entergy New Orleans undertook an internal restructuring, and in 2018, Entergy Arkansas and Entergy Mississippi also participated in internal restructurings under which these three Utility operating companies joined Entergy Louisiana as wholly-owned subsidiaries of Entergy Utility Holding Company, LLC. The change in ownership required Entergy to recognize Entergy Arkansas’s nuclear decommissioning liabilities for income tax purposes, which resulted in recognition of a gain for income tax purposes and a corresponding increase in the tax basis of assets, in accordance with the Internal Revenue Code and Treasury Regulations. Entergy determined that there was uncertainty regarding the treatment of certain aspects of the restructurings and recorded provisions for uncertain tax positions which are now considered to be effectively settled in accordance with accounting standards. The reversal of such provisions for uncertain tax positions results in a reduction of income tax expense of $156 million for Entergy Arkansas, $1 million for Entergy Mississippi, and $6 million for Entergy New Orleans. The IRS also required Entergy New Orleans to reverse a tax gain associated with the 2017 restructuring that had been previously recognized, allowing Entergy New Orleans to reduce its tax expense by $39 million. After the restructuring, Entergy Arkansas adopted a new method of accounting for income tax purposes in which its nuclear decommissioning costs are treated as production costs of electricity includable in cost of goods sold, which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return that was treated as an unrecognized tax benefit. In conjunction with the audit, Entergy agreed with the IRS adjustments concerning the nuclear decommissioning tax position allowing Entergy Arkansas to include $102 million of its decommissioning liability in cost of goods sold. Mark-to-Market Method of Accounting In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement as well as other intercompany power purchase agreements. The election resulted in a $2 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with the Vidalia contract and various other third-party and intercompany wholesale electric power purchase and sale agreements. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $132 million and a corresponding reduction of income tax expense. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for the Unit Power Sales Agreement and various intercompany wholesale electric contracts which resulted in a $1 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $139 million and a corresponding reduction of income tax expense. In 2018, Entergy Arkansas and Entergy Mississippi each accrued approximately $2 billion in deductible temporary differences related to mark-to-market tax accounting for the Unit Power Sales Agreement and various wholesale electric contracts. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The effective settlement of the mark-to-market tax position for Entergy Arkansas resulted in the accrual of an increase to tax expense of $40 million, which was offset by approximately $5 million of miscellaneous excess ADIT recognized as a result of the 2016-2018 IRS audit resolution. The net increase to tax expense is deferred as a regulatory asset, as discussed within the “ Regulatory and Other Matters ” section below. Restructuring of Entergy’s Non-Utility Operations Business During the 2016 to 2018 audit period, the ownership of certain of Entergy’s non-utility operations business nuclear power plants (previously reported as part of Entergy Wholesale Commodities) was restructured. Such restructuring transactions required Entergy to recognize the plants’ nuclear decommissioning liabilities for income tax purposes. The accrual of the nuclear decommissioning liabilities also required Entergy to recognize a gain for income tax purposes, a significant portion of which resulted in an increase in the tax basis of the assets. Because certain aspects of the restructuring transactions involved uncertainty, Entergy recorded a provision for uncertain tax positions. The IRS did not propose adjustments to the tax treatment of the restructuring transactions resulting in a net decrease to income tax expense of $288 million from the reversal of the provision for uncertain tax positions in fourth quarter 2023. Reduction of Net Operating Loss Carryovers The IRS audit reduced Entergy’s net operating loss carryover by $8 billion. A portion of Entergy’s audit adjustments were not offset by losses which resulted in a tax liability of $79 million, which was fully offset by prior deposits made by Entergy. Entergy received an assessment of interest in excess of prior deposits of $13 million in December 2023, and such interest was paid in January 2024. Net operating loss carryovers were reduced by $4 billion for Entergy Arkansas, $1 billion for Entergy Louisiana, $2 billion for Entergy Mississippi, $1 billion for Entergy New Orleans, and $40 million for System Energy. The IRS audit adjustments were also factored into the settle-up required under Entergy’s intercompany income tax allocation agreement, and such amounts were settled in the fourth quarter of 2023. Regulatory and Other Matters In accordance with prior regulatory agreements associated with the Entergy Louisiana and Entergy Gulf States Louisiana business combination and Entergy New Orleans restructuring and general rate-making principles, Entergy Louisiana and Entergy New Orleans, respectively, recorded a regulatory liabilit

Significant components of accumulated deferred income taxes and taxes accrued for Entergy Corporation and Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 2023 (In Thousands) Deferred tax liabilities: Plant basis differences - net ($6,451,189) ($6,192,156) Regulatory assets (1,003,045) (989,405) Nuclear decommissioning trusts/receivables (563,423) (467,267) Pension, net regulatory asset (303,007) (363,829) Combined unitary state taxes (3,600) (8,783) Power purchase agreements (89,614) (75,612) Accumulated storm damage provision — (2,474) Deferred fuel (23,305) (69,436) Other (206,648) (251,107) Total (8,643,831) (8,420,069) Deferred tax assets: Regulatory liabilities 1,394,937 1,247,530 Nuclear and other decommissioning liabilities 164,685 147,011 Pension and other post-employment benefits 22,646 116,222 Compensation 79,580 81,226 Accumulated deferred investment tax credit 52,709 55,928 Provision for allowances and contingencies 141,769 149,479 Unbilled/deferred revenues (9,960) 2,418 Net operating loss carryforwards 2,672,993 2,857,908 Capital losses and miscellaneous tax credits 111,325 107,009 Valuation allowance (338,508) (372,119) Other 212,563 220,055 Total 4,504,739 4,612,667 Non-current accrued taxes (including unrecognized tax benefits) (309,669) (422,213) Accumulated deferred income taxes and taxes accrued ($4,448,761) ($4,229,615) Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Carryover Description Carryover Amount Year(s) of expiration Federal net operating losses before 1/1/2018 $4.4 billion 2025-2037 Federal net operating losses - 1/1/2018 forward $13.9 billion N/A State net operating losses $4.3 billion 2028-2042 State net operating losses with no expiration $8.8 billion N/A Other federal and state carryforwards $134.5 million 2025-2028 Miscellaneous federal and state credits $138.8 million 2025-2044 As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes generated and reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount. Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $339 million as of December 31, 2024 and $372 million as of December 31, 2023 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. Certain accelerated tax deductions which generated taxable losses in various taxing jurisdictions, and which have a limited term carryover period, have resulted in the impairment of the realizability of such carryovers and are reflected in the valuation allowance disclosed above. Significant components of accumulated deferred income taxes and taxes accrued for the Registrant Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,530,196) ($2,729,299) ($849,623) ($272,182) ($727,242) ($466,361) Regulatory assets (219,773) (497,177) (37,374) (72,389) (100,959) (75,606) Nuclear decommissioning trusts/receivables (185,725) (202,364) — — — (175,341) Pension, net regulatory asset (101,887) (84,732) (26,064) (9,687) (16,569) — Power purchase agreements 11,993 (97,846) 1,140 (12,385) (5,148) — Deferred fuel — (4,785) (17,234) (1,247) — (78) Other (24,430) (106,590) (5,231) (5,133) (4,512) (13,572) Total (2,050,018) (3,722,793) (934,386) (373,023) (854,430) (730,958) Deferred tax assets: Regulatory liabilities 310,621 678,086 53,046 89,385 37,325 229,065 Nuclear and other decommissioning liabilities 127,933 18,649 — (407) 97 17,956 Pension and other post-employment benefits (29,923) 39,379 (8,989) (19,443) (23,403) (24,642) Compensation 4,851 7,119 3,277 1,394 2,596 515 Accumulated deferred investment tax credit 6,360 26,549 3,355 4,205 1,515 10,724 Provision for allowances and contingencies 31,686 59,448 11,361 23,998 4,358 225 Unbilled/deferred revenues 3,546 (24,017) 1,274 715 7,925 — Net operating loss carryforwards 126,255 336,128 305 30,740 50 69,611 Capital losses and miscellaneous tax credits 14,489 17,029 8,206 16,220 1,273 10,788 Other 11,608 54,207 1,096 1,692 1,189 — Total 607,426 1,212,577 72,931 148,499 32,925 314,242 Non-current accrued taxes (including unrecognized tax benefits) (46,577) 32,262 (8,661) 22,983 (47,344) (35,114) Accumulated deferred income taxes and taxes accrued ($1,489,169) ($2,477,954) ($870,116) ($201,541) ($868,849) ($451,830) 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,421,272) ($2,639,079) ($810,120) ($272,187) ($671,072) ($450,559) Regulatory assets (241,427) (500,395) (41,519) (23,618) (104,562) (76,522) Nuclear decommissioning trusts/receivables (154,106) (173,402) — — — (139,858) Pension, net regulatory asset (96,853) (82,305) (24,342) (9,216) (17,522) (18,895) Power purchase agreements 15,993 (112,292) 1,140 (12,516) (4,551) — Accumulated storm damage provision — — — — (1,387) — Deferred fuel — (17,065) (21,137) (1,563) (29,194) (37) Other (21,187) (126,952) (6,844) (4,270) (3,301) (9,051) Total (1,918,852) (3,651,490) (902,822) (323,370) (831,589) (694,922) Deferred tax assets: Regulatory liabilities 296,278 575,459 54,586 42,921 41,137 240,310 Nuclear and other decommissioning liabilities 118,301 9,055 — — 97 19,259 Pension and other post-employment benefits (28,868) 46,837 (10,064) (19,354) (21,977) (2,641) Compensation 4,054 6,078 3,649 1,268 2,181 406 Accumulated deferred investment tax credit 6,761 27,902 3,446 4,431 1,672 11,717 Provision for allowances and contingencies 23,956 70,297 10,072 25,846 8,659 225 Unbilled/deferred revenues 5,962 (20,375) 6,194 1,045 8,365 — Net operating loss carryforwards 94,321 459,553 8,375 26,227 61 35,089 Capital losses and miscellaneous tax credits 7,137 13,073 7,613 15,684 1,655 13,211 Other 17,072 52,438 1,556 (235) 1,740 — Total 544,974 1,240,317 85,427 97,833 43,590 317,576 Non-current accrued taxes (including unrecognized tax benefits) (63,175) 19,731 (4,349) 29,922 (26,906) (28,398) Accumulated deferred income taxes and taxes accrued ($1,437,053) ($2,391,442) ($821,744) ($195,615) ($814,905) ($405,744) The Registrant Subsidiaries’ estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy Federal net operating losses before 1/1/2018 $— million $812.8 million $— million $82.6 million $— million $— million Year(s) of expiration N/A 2035-2037 N/A 2037 N/A N/A Federal net operating losses - 1/1/2018 forward $576 million $2.6 billion $— million $26.4 million $1.5 billion $264.7 million Year(s) of expiration N/A N/A N/A N/A N/A N/A State net operating losses $597.4 million $5.8 billion $7.1 million $336.6 million $1 million $370.1 million Year(s) of expiration 2028-2032 N/A 2039-2042 N/A 2028 2040-2044 Misc. federal credits $12.9 million $21 million $4.9 million $16.7 million $0.8 million $5.7 million Year(s) of expiration 2038-2044 2035-2044 2038-2044 2037-2044 2039-2044 2029-2044 State credits $— million $1.1 million $8.3 million $— million $1.3 million $17 million Year(s) of expiration N/A N/A 2025-2028 N/A 2027-2033 2025-2028 Unrecognized tax benefits Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements. If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded. A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows: 2024 2023 2022 (In Thousands) Gross balance at January 1 $2,439,910 $6,393,599 $5,759,968 Additions based on tax positions related to the current year 12,731 332,884 792,134 Additions for tax positions of prior years 21,149 194,894 37,259 Reductions for tax positions of prior years (a) (85,715) (1,300,381) (195,762) Settlements (a) (33,208) (3,181,086) — Gross balance at December 31 2,354,867 2,439,910 6,393,599 Offsets to gross unrecognized tax benefits: Loss and tax credit carryovers (2,079,778) (2,160,484) (5,566,212) Cash paid to taxing authorities (27,000) — (82,000) Unrecognized tax benefits net of unused tax attributes and payments (b) $248,089 $279,426 $745,387 (a) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. Amounts in 2024 are primarily related to the resolution of 2014-2018 Arkansas tax examination as discussed in “ Income Tax Audits - State Income Tax Audits ” below. (b) Potential tax liability above what is payable on tax returns. The balances of unrecognized tax benefits include $1,900 million, $1,899 million, and $3,254 million as of December 31, 2024, 2023, and 2022, respectively, which, if recognized, would lower the effective income tax rates. Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $455 million, $541 million, and $3,140 million as of December 31, 2024, 2023, and 2022, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense. Entergy’s December 31, 2024, 2023, and 2022 accrued balance for the possible payment of interest is approximately $32 million, $39 million, and $50 million, respectively. Interest (net-of-tax) of ($7) million, ($11) million, and $8 million was recorded in 2024, 2023, and 2022, respectively.

(b) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. The Registrant Subsidiaries’ balances of unrecognized tax benefits included amounts which, if recognized, would have reduced income tax expense as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $32.6 $57.2 $377.9 Entergy Louisiana $868.2 $862.5 $720.8 Entergy Mississippi $1.3 $1.0 $151.2 Entergy New Orleans $18.3 $18.2 $310.7 Entergy Texas $50.3 $2.9 $3.3 System Energy $4.0 $3.1 $2.5 Accrued balances for the possible payment of interest related to unrecognized tax benefits for the Registrant Subsidiaries are as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $8.4 $7.8 $4.3 Entergy Louisiana $5.1 $1.5 $4.1 Entergy Mississippi $3.2 $2.1 $3.1 Entergy New Orleans $0.6 $0.6 $6.4 Entergy Texas $0.5 $— $1.1 System Energy $2.9 $1.9 $1.9 The Registrant Subsidiaries record interest and penalties related to unrecognized tax benefits in income tax expense. No penalties were recorded in 2024, 2023, and 2022. Interest (net-of-tax) was recorded as follows: 2024 2023 2022 (In Millions) Entergy Arkansas $0.6 $3.5 $1.6 Entergy Louisiana $3.6 ($2.6) $0.4 Entergy Mississippi $1.1 ($1.0) $0.7 Entergy New Orleans $— ($5.8) $1.2 Entergy Texas $0.5 ($1.1) $— System Energy $1.0 $— ($10.2) Income Tax Audits Entergy and its subsidiaries file U.S. federal and various state income tax returns. IRS examinations are complete for years before 2019. All state taxing authorities’ examinations are complete for years before 2016. Entergy regularly defends its positions and works with the IRS to resolve audits. The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months. 2016-2018 IRS Audit The IRS completed its examination of the 2016 through 2018 tax years and issued a Revenue Agent Report (RAR) for each federal filer under audit in November 2023. Entergy agreed to all adjustments contained in the RARs. Entergy and the Registrant Subsidiaries recorded all the material effects resulting from the RARs in the fourth quarter of 2023. Utility Restructurings In 2017, Entergy New Orleans undertook an internal restructuring, and in 2018, Entergy Arkansas and Entergy Mississippi also participated in internal restructurings under which these three Utility operating companies joined Entergy Louisiana as wholly-owned subsidiaries of Entergy Utility Holding Company, LLC. The change in ownership required Entergy to recognize Entergy Arkansas’s nuclear decommissioning liabilities for income tax purposes, which resulted in recognition of a gain for income tax purposes and a corresponding increase in the tax basis of assets, in accordance with the Internal Revenue Code and Treasury Regulations. Entergy determined that there was uncertainty regarding the treatment of certain aspects of the restructurings and recorded provisions for uncertain tax positions which are now considered to be effectively settled in accordance with accounting standards. The reversal of such provisions for uncertain tax positions results in a reduction of income tax expense of $156 million for Entergy Arkansas, $1 million for Entergy Mississippi, and $6 million for Entergy New Orleans. The IRS also required Entergy New Orleans to reverse a tax gain associated with the 2017 restructuring that had been previously recognized, allowing Entergy New Orleans to reduce its tax expense by $39 million. After the restructuring, Entergy Arkansas adopted a new method of accounting for income tax purposes in which its nuclear decommissioning costs are treated as production costs of electricity includable in cost of goods sold, which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return that was treated as an unrecognized tax benefit. In conjunction with the audit, Entergy agreed with the IRS adjustments concerning the nuclear decommissioning tax position allowing Entergy Arkansas to include $102 million of its decommissioning liability in cost of goods sold. Mark-to-Market Method of Accounting In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement as well as other intercompany power purchase agreements. The election resulted in a $2 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with the Vidalia contract and various other third-party and intercompany wholesale electric power purchase and sale agreements. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $132 million and a corresponding reduction of income tax expense. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for the Unit Power Sales Agreement and various intercompany wholesale electric contracts which resulted in a $1 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $139 million and a corresponding reduction of income tax expense. In 2018, Entergy Arkansas and Entergy Mississippi each accrued approximately $2 billion in deductible temporary differences related to mark-to-market tax accounting for the Unit Power Sales Agreement and various wholesale electric contracts. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The effective settlement of the mark-to-market tax position for Entergy Arkansas resulted in the accrual of an increase to tax expense of $40 million, which was offset by approximately $5 million of miscellaneous excess ADIT recognized as a result of the 2016-2018 IRS audit resolution. The net increase to tax expense is deferred as a regulatory asset, as discussed within the “ Regulatory and Other Matters ” section below. Restructuring of Entergy’s Non-Utility Operations Business During the 2016 to 2018 audit period, the ownership of certain of Entergy’s non-utility operations business nuclear power plants (previously reported as part of Entergy Wholesale Commodities) was restructured. Such restructuring transactions required Entergy to recognize the plants’ nuclear decommissioning liabilities for income tax purposes. The accrual of the nuclear decommissioning liabilities also required Entergy to recognize a gain for income tax purposes, a significant portion of which resulted in an increase in the tax basis of the assets. Because certain aspects of the restructuring transactions involved uncertainty, Entergy recorded a provision for uncertain tax positions. The IRS did not propose adjustments to the tax treatment of the restructuring transactions resulting in a net decrease to income tax expense of $288 million from the reversal of the provision for uncertain tax positions in fourth quarter 2023. Reduction of Net Operating Loss Carryovers The IRS audit reduced Entergy’s net operating loss carryover by $8 billion. A portion of Entergy’s audit adjustments were not offset by losses which resulted in a tax liability of $79 million, which was fully offset by prior deposits made by Entergy. Entergy received an assessment of interest in excess of prior deposits of $13 million in December 2023, and such interest was paid in January 2024. Net operating loss carryovers were reduced by $4 billion for Entergy Arkansas, $1 billion for Entergy Louisiana, $2 billion for Entergy Mississippi, $1 billion for Entergy New Orleans, and $40 million for System Energy. The IRS audit adjustments were also factored into the settle-up required under Entergy’s intercompany income tax allocation agreement, and such amounts were settled in the fourth quarter of 2023. Regulatory and Other Matters In accordance with prior regulatory agreements associated with the Entergy Louisiana and Entergy Gulf States Louisiana business combination and Entergy New Orleans restructuring and general rate-making principles, Entergy Louisiana and Entergy New Orleans, respectively, recorded a regulatory liabilit

Significant components of accumulated deferred income taxes and taxes accrued for Entergy Corporation and Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 2023 (In Thousands) Deferred tax liabilities: Plant basis differences - net ($6,451,189) ($6,192,156) Regulatory assets (1,003,045) (989,405) Nuclear decommissioning trusts/receivables (563,423) (467,267) Pension, net regulatory asset (303,007) (363,829) Combined unitary state taxes (3,600) (8,783) Power purchase agreements (89,614) (75,612) Accumulated storm damage provision — (2,474) Deferred fuel (23,305) (69,436) Other (206,648) (251,107) Total (8,643,831) (8,420,069) Deferred tax assets: Regulatory liabilities 1,394,937 1,247,530 Nuclear and other decommissioning liabilities 164,685 147,011 Pension and other post-employment benefits 22,646 116,222 Compensation 79,580 81,226 Accumulated deferred investment tax credit 52,709 55,928 Provision for allowances and contingencies 141,769 149,479 Unbilled/deferred revenues (9,960) 2,418 Net operating loss carryforwards 2,672,993 2,857,908 Capital losses and miscellaneous tax credits 111,325 107,009 Valuation allowance (338,508) (372,119) Other 212,563 220,055 Total 4,504,739 4,612,667 Non-current accrued taxes (including unrecognized tax benefits) (309,669) (422,213) Accumulated deferred income taxes and taxes accrued ($4,448,761) ($4,229,615) Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Carryover Description Carryover Amount Year(s) of expiration Federal net operating losses before 1/1/2018 $4.4 billion 2025-2037 Federal net operating losses - 1/1/2018 forward $13.9 billion N/A State net operating losses $4.3 billion 2028-2042 State net operating losses with no expiration $8.8 billion N/A Other federal and state carryforwards $134.5 million 2025-2028 Miscellaneous federal and state credits $138.8 million 2025-2044 As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes generated and reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount. Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $339 million as of December 31, 2024 and $372 million as of December 31, 2023 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. Certain accelerated tax deductions which generated taxable losses in various taxing jurisdictions, and which have a limited term carryover period, have resulted in the impairment of the realizability of such carryovers and are reflected in the valuation allowance disclosed above. Significant components of accumulated deferred income taxes and taxes accrued for the Registrant Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,530,196) ($2,729,299) ($849,623) ($272,182) ($727,242) ($466,361) Regulatory assets (219,773) (497,177) (37,374) (72,389) (100,959) (75,606) Nuclear decommissioning trusts/receivables (185,725) (202,364) — — — (175,341) Pension, net regulatory asset (101,887) (84,732) (26,064) (9,687) (16,569) — Power purchase agreements 11,993 (97,846) 1,140 (12,385) (5,148) — Deferred fuel — (4,785) (17,234) (1,247) — (78) Other (24,430) (106,590) (5,231) (5,133) (4,512) (13,572) Total (2,050,018) (3,722,793) (934,386) (373,023) (854,430) (730,958) Deferred tax assets: Regulatory liabilities 310,621 678,086 53,046 89,385 37,325 229,065 Nuclear and other decommissioning liabilities 127,933 18,649 — (407) 97 17,956 Pension and other post-employment benefits (29,923) 39,379 (8,989) (19,443) (23,403) (24,642) Compensation 4,851 7,119 3,277 1,394 2,596 515 Accumulated deferred investment tax credit 6,360 26,549 3,355 4,205 1,515 10,724 Provision for allowances and contingencies 31,686 59,448 11,361 23,998 4,358 225 Unbilled/deferred revenues 3,546 (24,017) 1,274 715 7,925 — Net operating loss carryforwards 126,255 336,128 305 30,740 50 69,611 Capital losses and miscellaneous tax credits 14,489 17,029 8,206 16,220 1,273 10,788 Other 11,608 54,207 1,096 1,692 1,189 — Total 607,426 1,212,577 72,931 148,499 32,925 314,242 Non-current accrued taxes (including unrecognized tax benefits) (46,577) 32,262 (8,661) 22,983 (47,344) (35,114) Accumulated deferred income taxes and taxes accrued ($1,489,169) ($2,477,954) ($870,116) ($201,541) ($868,849) ($451,830) 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,421,272) ($2,639,079) ($810,120) ($272,187) ($671,072) ($450,559) Regulatory assets (241,427) (500,395) (41,519) (23,618) (104,562) (76,522) Nuclear decommissioning trusts/receivables (154,106) (173,402) — — — (139,858) Pension, net regulatory asset (96,853) (82,305) (24,342) (9,216) (17,522) (18,895) Power purchase agreements 15,993 (112,292) 1,140 (12,516) (4,551) — Accumulated storm damage provision — — — — (1,387) — Deferred fuel — (17,065) (21,137) (1,563) (29,194) (37) Other (21,187) (126,952) (6,844) (4,270) (3,301) (9,051) Total (1,918,852) (3,651,490) (902,822) (323,370) (831,589) (694,922) Deferred tax assets: Regulatory liabilities 296,278 575,459 54,586 42,921 41,137 240,310 Nuclear and other decommissioning liabilities 118,301 9,055 — — 97 19,259 Pension and other post-employment benefits (28,868) 46,837 (10,064) (19,354) (21,977) (2,641) Compensation 4,054 6,078 3,649 1,268 2,181 406 Accumulated deferred investment tax credit 6,761 27,902 3,446 4,431 1,672 11,717 Provision for allowances and contingencies 23,956 70,297 10,072 25,846 8,659 225 Unbilled/deferred revenues 5,962 (20,375) 6,194 1,045 8,365 — Net operating loss carryforwards 94,321 459,553 8,375 26,227 61 35,089 Capital losses and miscellaneous tax credits 7,137 13,073 7,613 15,684 1,655 13,211 Other 17,072 52,438 1,556 (235) 1,740 — Total 544,974 1,240,317 85,427 97,833 43,590 317,576 Non-current accrued taxes (including unrecognized tax benefits) (63,175) 19,731 (4,349) 29,922 (26,906) (28,398) Accumulated deferred income taxes and taxes accrued ($1,437,053) ($2,391,442) ($821,744) ($195,615) ($814,905) ($405,744) The Registrant Subsidiaries’ estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy Federal net operating losses before 1/1/2018 $— million $812.8 million $— million $82.6 million $— million $— million Year(s) of expiration N/A 2035-2037 N/A 2037 N/A N/A Federal net operating losses - 1/1/2018 forward $576 million $2.6 billion $— million $26.4 million $1.5 billion $264.7 million Year(s) of expiration N/A N/A N/A N/A N/A N/A State net operating losses $597.4 million $5.8 billion $7.1 million $336.6 million $1 million $370.1 million Year(s) of expiration 2028-2032 N/A 2039-2042 N/A 2028 2040-2044 Misc. federal credits $12.9 million $21 million $4.9 million $16.7 million $0.8 million $5.7 million Year(s) of expiration 2038-2044 2035-2044 2038-2044 2037-2044 2039-2044 2029-2044 State credits $— million $1.1 million $8.3 million $— million $1.3 million $17 million Year(s) of expiration N/A N/A 2025-2028 N/A 2027-2033 2025-2028 Unrecognized tax benefits Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements. If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded. A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows: 2024 2023 2022 (In Thousands) Gross balance at January 1 $2,439,910 $6,393,599 $5,759,968 Additions based on tax positions related to the current year 12,731 332,884 792,134 Additions for tax positions of prior years 21,149 194,894 37,259 Reductions for tax positions of prior years (a) (85,715) (1,300,381) (195,762) Settlements (a) (33,208) (3,181,086) — Gross balance at December 31 2,354,867 2,439,910 6,393,599 Offsets to gross unrecognized tax benefits: Loss and tax credit carryovers (2,079,778) (2,160,484) (5,566,212) Cash paid to taxing authorities (27,000) — (82,000) Unrecognized tax benefits net of unused tax attributes and payments (b) $248,089 $279,426 $745,387 (a) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. Amounts in 2024 are primarily related to the resolution of 2014-2018 Arkansas tax examination as discussed in “ Income Tax Audits - State Income Tax Audits ” below. (b) Potential tax liability above what is payable on tax returns. The balances of unrecognized tax benefits include $1,900 million, $1,899 million, and $3,254 million as of December 31, 2024, 2023, and 2022, respectively, which, if recognized, would lower the effective income tax rates. Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $455 million, $541 million, and $3,140 million as of December 31, 2024, 2023, and 2022, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense. Entergy’s December 31, 2024, 2023, and 2022 accrued balance for the possible payment of interest is approximately $32 million, $39 million, and $50 million, respectively. Interest (net-of-tax) of ($7) million, ($11) million, and $8 million was recorded in 2024, 2023, and 2022, respectively.

(b) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. The Registrant Subsidiaries’ balances of unrecognized tax benefits included amounts which, if recognized, would have reduced income tax expense as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $32.6 $57.2 $377.9 Entergy Louisiana $868.2 $862.5 $720.8 Entergy Mississippi $1.3 $1.0 $151.2 Entergy New Orleans $18.3 $18.2 $310.7 Entergy Texas $50.3 $2.9 $3.3 System Energy $4.0 $3.1 $2.5 Accrued balances for the possible payment of interest related to unrecognized tax benefits for the Registrant Subsidiaries are as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $8.4 $7.8 $4.3 Entergy Louisiana $5.1 $1.5 $4.1 Entergy Mississippi $3.2 $2.1 $3.1 Entergy New Orleans $0.6 $0.6 $6.4 Entergy Texas $0.5 $— $1.1 System Energy $2.9 $1.9 $1.9 The Registrant Subsidiaries record interest and penalties related to unrecognized tax benefits in income tax expense. No penalties were recorded in 2024, 2023, and 2022. Interest (net-of-tax) was recorded as follows: 2024 2023 2022 (In Millions) Entergy Arkansas $0.6 $3.5 $1.6 Entergy Louisiana $3.6 ($2.6) $0.4 Entergy Mississippi $1.1 ($1.0) $0.7 Entergy New Orleans $— ($5.8) $1.2 Entergy Texas $0.5 ($1.1) $— System Energy $1.0 $— ($10.2) Income Tax Audits Entergy and its subsidiaries file U.S. federal and various state income tax returns. IRS examinations are complete for years before 2019. All state taxing authorities’ examinations are complete for years before 2016. Entergy regularly defends its positions and works with the IRS to resolve audits. The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months. 2016-2018 IRS Audit The IRS completed its examination of the 2016 through 2018 tax years and issued a Revenue Agent Report (RAR) for each federal filer under audit in November 2023. Entergy agreed to all adjustments contained in the RARs. Entergy and the Registrant Subsidiaries recorded all the material effects resulting from the RARs in the fourth quarter of 2023. Utility Restructurings In 2017, Entergy New Orleans undertook an internal restructuring, and in 2018, Entergy Arkansas and Entergy Mississippi also participated in internal restructurings under which these three Utility operating companies joined Entergy Louisiana as wholly-owned subsidiaries of Entergy Utility Holding Company, LLC. The change in ownership required Entergy to recognize Entergy Arkansas’s nuclear decommissioning liabilities for income tax purposes, which resulted in recognition of a gain for income tax purposes and a corresponding increase in the tax basis of assets, in accordance with the Internal Revenue Code and Treasury Regulations. Entergy determined that there was uncertainty regarding the treatment of certain aspects of the restructurings and recorded provisions for uncertain tax positions which are now considered to be effectively settled in accordance with accounting standards. The reversal of such provisions for uncertain tax positions results in a reduction of income tax expense of $156 million for Entergy Arkansas, $1 million for Entergy Mississippi, and $6 million for Entergy New Orleans. The IRS also required Entergy New Orleans to reverse a tax gain associated with the 2017 restructuring that had been previously recognized, allowing Entergy New Orleans to reduce its tax expense by $39 million. After the restructuring, Entergy Arkansas adopted a new method of accounting for income tax purposes in which its nuclear decommissioning costs are treated as production costs of electricity includable in cost of goods sold, which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return that was treated as an unrecognized tax benefit. In conjunction with the audit, Entergy agreed with the IRS adjustments concerning the nuclear decommissioning tax position allowing Entergy Arkansas to include $102 million of its decommissioning liability in cost of goods sold. Mark-to-Market Method of Accounting In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement as well as other intercompany power purchase agreements. The election resulted in a $2 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with the Vidalia contract and various other third-party and intercompany wholesale electric power purchase and sale agreements. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $132 million and a corresponding reduction of income tax expense. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for the Unit Power Sales Agreement and various intercompany wholesale electric contracts which resulted in a $1 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $139 million and a corresponding reduction of income tax expense. In 2018, Entergy Arkansas and Entergy Mississippi each accrued approximately $2 billion in deductible temporary differences related to mark-to-market tax accounting for the Unit Power Sales Agreement and various wholesale electric contracts. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The effective settlement of the mark-to-market tax position for Entergy Arkansas resulted in the accrual of an increase to tax expense of $40 million, which was offset by approximately $5 million of miscellaneous excess ADIT recognized as a result of the 2016-2018 IRS audit resolution. The net increase to tax expense is deferred as a regulatory asset, as discussed within the “ Regulatory and Other Matters ” section below. Restructuring of Entergy’s Non-Utility Operations Business During the 2016 to 2018 audit period, the ownership of certain of Entergy’s non-utility operations business nuclear power plants (previously reported as part of Entergy Wholesale Commodities) was restructured. Such restructuring transactions required Entergy to recognize the plants’ nuclear decommissioning liabilities for income tax purposes. The accrual of the nuclear decommissioning liabilities also required Entergy to recognize a gain for income tax purposes, a significant portion of which resulted in an increase in the tax basis of the assets. Because certain aspects of the restructuring transactions involved uncertainty, Entergy recorded a provision for uncertain tax positions. The IRS did not propose adjustments to the tax treatment of the restructuring transactions resulting in a net decrease to income tax expense of $288 million from the reversal of the provision for uncertain tax positions in fourth quarter 2023. Reduction of Net Operating Loss Carryovers The IRS audit reduced Entergy’s net operating loss carryover by $8 billion. A portion of Entergy’s audit adjustments were not offset by losses which resulted in a tax liability of $79 million, which was fully offset by prior deposits made by Entergy. Entergy received an assessment of interest in excess of prior deposits of $13 million in December 2023, and such interest was paid in January 2024. Net operating loss carryovers were reduced by $4 billion for Entergy Arkansas, $1 billion for Entergy Louisiana, $2 billion for Entergy Mississippi, $1 billion for Entergy New Orleans, and $40 million for System Energy. The IRS audit adjustments were also factored into the settle-up required under Entergy’s intercompany income tax allocation agreement, and such amounts were settled in the fourth quarter of 2023. Regulatory and Other Matters In accordance with prior regulatory agreements associated with the Entergy Louisiana and Entergy Gulf States Louisiana business combination and Entergy New Orleans restructuring and general rate-making principles, Entergy Louisiana and Entergy New Orleans, respectively, recorded a regulatory liabilit

Significant components of accumulated deferred income taxes and taxes accrued for Entergy Corporation and Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 2023 (In Thousands) Deferred tax liabilities: Plant basis differences - net ($6,451,189) ($6,192,156) Regulatory assets (1,003,045) (989,405) Nuclear decommissioning trusts/receivables (563,423) (467,267) Pension, net regulatory asset (303,007) (363,829) Combined unitary state taxes (3,600) (8,783) Power purchase agreements (89,614) (75,612) Accumulated storm damage provision — (2,474) Deferred fuel (23,305) (69,436) Other (206,648) (251,107) Total (8,643,831) (8,420,069) Deferred tax assets: Regulatory liabilities 1,394,937 1,247,530 Nuclear and other decommissioning liabilities 164,685 147,011 Pension and other post-employment benefits 22,646 116,222 Compensation 79,580 81,226 Accumulated deferred investment tax credit 52,709 55,928 Provision for allowances and contingencies 141,769 149,479 Unbilled/deferred revenues (9,960) 2,418 Net operating loss carryforwards 2,672,993 2,857,908 Capital losses and miscellaneous tax credits 111,325 107,009 Valuation allowance (338,508) (372,119) Other 212,563 220,055 Total 4,504,739 4,612,667 Non-current accrued taxes (including unrecognized tax benefits) (309,669) (422,213) Accumulated deferred income taxes and taxes accrued ($4,448,761) ($4,229,615) Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Carryover Description Carryover Amount Year(s) of expiration Federal net operating losses before 1/1/2018 $4.4 billion 2025-2037 Federal net operating losses - 1/1/2018 forward $13.9 billion N/A State net operating losses $4.3 billion 2028-2042 State net operating losses with no expiration $8.8 billion N/A Other federal and state carryforwards $134.5 million 2025-2028 Miscellaneous federal and state credits $138.8 million 2025-2044 As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes generated and reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount. Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $339 million as of December 31, 2024 and $372 million as of December 31, 2023 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. Certain accelerated tax deductions which generated taxable losses in various taxing jurisdictions, and which have a limited term carryover period, have resulted in the impairment of the realizability of such carryovers and are reflected in the valuation allowance disclosed above. Significant components of accumulated deferred income taxes and taxes accrued for the Registrant Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,530,196) ($2,729,299) ($849,623) ($272,182) ($727,242) ($466,361) Regulatory assets (219,773) (497,177) (37,374) (72,389) (100,959) (75,606) Nuclear decommissioning trusts/receivables (185,725) (202,364) — — — (175,341) Pension, net regulatory asset (101,887) (84,732) (26,064) (9,687) (16,569) — Power purchase agreements 11,993 (97,846) 1,140 (12,385) (5,148) — Deferred fuel — (4,785) (17,234) (1,247) — (78) Other (24,430) (106,590) (5,231) (5,133) (4,512) (13,572) Total (2,050,018) (3,722,793) (934,386) (373,023) (854,430) (730,958) Deferred tax assets: Regulatory liabilities 310,621 678,086 53,046 89,385 37,325 229,065 Nuclear and other decommissioning liabilities 127,933 18,649 — (407) 97 17,956 Pension and other post-employment benefits (29,923) 39,379 (8,989) (19,443) (23,403) (24,642) Compensation 4,851 7,119 3,277 1,394 2,596 515 Accumulated deferred investment tax credit 6,360 26,549 3,355 4,205 1,515 10,724 Provision for allowances and contingencies 31,686 59,448 11,361 23,998 4,358 225 Unbilled/deferred revenues 3,546 (24,017) 1,274 715 7,925 — Net operating loss carryforwards 126,255 336,128 305 30,740 50 69,611 Capital losses and miscellaneous tax credits 14,489 17,029 8,206 16,220 1,273 10,788 Other 11,608 54,207 1,096 1,692 1,189 — Total 607,426 1,212,577 72,931 148,499 32,925 314,242 Non-current accrued taxes (including unrecognized tax benefits) (46,577) 32,262 (8,661) 22,983 (47,344) (35,114) Accumulated deferred income taxes and taxes accrued ($1,489,169) ($2,477,954) ($870,116) ($201,541) ($868,849) ($451,830) 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,421,272) ($2,639,079) ($810,120) ($272,187) ($671,072) ($450,559) Regulatory assets (241,427) (500,395) (41,519) (23,618) (104,562) (76,522) Nuclear decommissioning trusts/receivables (154,106) (173,402) — — — (139,858) Pension, net regulatory asset (96,853) (82,305) (24,342) (9,216) (17,522) (18,895) Power purchase agreements 15,993 (112,292) 1,140 (12,516) (4,551) — Accumulated storm damage provision — — — — (1,387) — Deferred fuel — (17,065) (21,137) (1,563) (29,194) (37) Other (21,187) (126,952) (6,844) (4,270) (3,301) (9,051) Total (1,918,852) (3,651,490) (902,822) (323,370) (831,589) (694,922) Deferred tax assets: Regulatory liabilities 296,278 575,459 54,586 42,921 41,137 240,310 Nuclear and other decommissioning liabilities 118,301 9,055 — — 97 19,259 Pension and other post-employment benefits (28,868) 46,837 (10,064) (19,354) (21,977) (2,641) Compensation 4,054 6,078 3,649 1,268 2,181 406 Accumulated deferred investment tax credit 6,761 27,902 3,446 4,431 1,672 11,717 Provision for allowances and contingencies 23,956 70,297 10,072 25,846 8,659 225 Unbilled/deferred revenues 5,962 (20,375) 6,194 1,045 8,365 — Net operating loss carryforwards 94,321 459,553 8,375 26,227 61 35,089 Capital losses and miscellaneous tax credits 7,137 13,073 7,613 15,684 1,655 13,211 Other 17,072 52,438 1,556 (235) 1,740 — Total 544,974 1,240,317 85,427 97,833 43,590 317,576 Non-current accrued taxes (including unrecognized tax benefits) (63,175) 19,731 (4,349) 29,922 (26,906) (28,398) Accumulated deferred income taxes and taxes accrued ($1,437,053) ($2,391,442) ($821,744) ($195,615) ($814,905) ($405,744) The Registrant Subsidiaries’ estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy Federal net operating losses before 1/1/2018 $— million $812.8 million $— million $82.6 million $— million $— million Year(s) of expiration N/A 2035-2037 N/A 2037 N/A N/A Federal net operating losses - 1/1/2018 forward $576 million $2.6 billion $— million $26.4 million $1.5 billion $264.7 million Year(s) of expiration N/A N/A N/A N/A N/A N/A State net operating losses $597.4 million $5.8 billion $7.1 million $336.6 million $1 million $370.1 million Year(s) of expiration 2028-2032 N/A 2039-2042 N/A 2028 2040-2044 Misc. federal credits $12.9 million $21 million $4.9 million $16.7 million $0.8 million $5.7 million Year(s) of expiration 2038-2044 2035-2044 2038-2044 2037-2044 2039-2044 2029-2044 State credits $— million $1.1 million $8.3 million $— million $1.3 million $17 million Year(s) of expiration N/A N/A 2025-2028 N/A 2027-2033 2025-2028 Unrecognized tax benefits Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements. If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded. A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows: 2024 2023 2022 (In Thousands) Gross balance at January 1 $2,439,910 $6,393,599 $5,759,968 Additions based on tax positions related to the current year 12,731 332,884 792,134 Additions for tax positions of prior years 21,149 194,894 37,259 Reductions for tax positions of prior years (a) (85,715) (1,300,381) (195,762) Settlements (a) (33,208) (3,181,086) — Gross balance at December 31 2,354,867 2,439,910 6,393,599 Offsets to gross unrecognized tax benefits: Loss and tax credit carryovers (2,079,778) (2,160,484) (5,566,212) Cash paid to taxing authorities (27,000) — (82,000) Unrecognized tax benefits net of unused tax attributes and payments (b) $248,089 $279,426 $745,387 (a) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. Amounts in 2024 are primarily related to the resolution of 2014-2018 Arkansas tax examination as discussed in “ Income Tax Audits - State Income Tax Audits ” below. (b) Potential tax liability above what is payable on tax returns. The balances of unrecognized tax benefits include $1,900 million, $1,899 million, and $3,254 million as of December 31, 2024, 2023, and 2022, respectively, which, if recognized, would lower the effective income tax rates. Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $455 million, $541 million, and $3,140 million as of December 31, 2024, 2023, and 2022, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense. Entergy’s December 31, 2024, 2023, and 2022 accrued balance for the possible payment of interest is approximately $32 million, $39 million, and $50 million, respectively. Interest (net-of-tax) of ($7) million, ($11) million, and $8 million was recorded in 2024, 2023, and 2022, respectively.

(b) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. The Registrant Subsidiaries’ balances of unrecognized tax benefits included amounts which, if recognized, would have reduced income tax expense as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $32.6 $57.2 $377.9 Entergy Louisiana $868.2 $862.5 $720.8 Entergy Mississippi $1.3 $1.0 $151.2 Entergy New Orleans $18.3 $18.2 $310.7 Entergy Texas $50.3 $2.9 $3.3 System Energy $4.0 $3.1 $2.5 Accrued balances for the possible payment of interest related to unrecognized tax benefits for the Registrant Subsidiaries are as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $8.4 $7.8 $4.3 Entergy Louisiana $5.1 $1.5 $4.1 Entergy Mississippi $3.2 $2.1 $3.1 Entergy New Orleans $0.6 $0.6 $6.4 Entergy Texas $0.5 $— $1.1 System Energy $2.9 $1.9 $1.9 The Registrant Subsidiaries record interest and penalties related to unrecognized tax benefits in income tax expense. No penalties were recorded in 2024, 2023, and 2022. Interest (net-of-tax) was recorded as follows: 2024 2023 2022 (In Millions) Entergy Arkansas $0.6 $3.5 $1.6 Entergy Louisiana $3.6 ($2.6) $0.4 Entergy Mississippi $1.1 ($1.0) $0.7 Entergy New Orleans $— ($5.8) $1.2 Entergy Texas $0.5 ($1.1) $— System Energy $1.0 $— ($10.2) Income Tax Audits Entergy and its subsidiaries file U.S. federal and various state income tax returns. IRS examinations are complete for years before 2019. All state taxing authorities’ examinations are complete for years before 2016. Entergy regularly defends its positions and works with the IRS to resolve audits. The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months. 2016-2018 IRS Audit The IRS completed its examination of the 2016 through 2018 tax years and issued a Revenue Agent Report (RAR) for each federal filer under audit in November 2023. Entergy agreed to all adjustments contained in the RARs. Entergy and the Registrant Subsidiaries recorded all the material effects resulting from the RARs in the fourth quarter of 2023. Utility Restructurings In 2017, Entergy New Orleans undertook an internal restructuring, and in 2018, Entergy Arkansas and Entergy Mississippi also participated in internal restructurings under which these three Utility operating companies joined Entergy Louisiana as wholly-owned subsidiaries of Entergy Utility Holding Company, LLC. The change in ownership required Entergy to recognize Entergy Arkansas’s nuclear decommissioning liabilities for income tax purposes, which resulted in recognition of a gain for income tax purposes and a corresponding increase in the tax basis of assets, in accordance with the Internal Revenue Code and Treasury Regulations. Entergy determined that there was uncertainty regarding the treatment of certain aspects of the restructurings and recorded provisions for uncertain tax positions which are now considered to be effectively settled in accordance with accounting standards. The reversal of such provisions for uncertain tax positions results in a reduction of income tax expense of $156 million for Entergy Arkansas, $1 million for Entergy Mississippi, and $6 million for Entergy New Orleans. The IRS also required Entergy New Orleans to reverse a tax gain associated with the 2017 restructuring that had been previously recognized, allowing Entergy New Orleans to reduce its tax expense by $39 million. After the restructuring, Entergy Arkansas adopted a new method of accounting for income tax purposes in which its nuclear decommissioning costs are treated as production costs of electricity includable in cost of goods sold, which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return that was treated as an unrecognized tax benefit. In conjunction with the audit, Entergy agreed with the IRS adjustments concerning the nuclear decommissioning tax position allowing Entergy Arkansas to include $102 million of its decommissioning liability in cost of goods sold. Mark-to-Market Method of Accounting In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement as well as other intercompany power purchase agreements. The election resulted in a $2 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with the Vidalia contract and various other third-party and intercompany wholesale electric power purchase and sale agreements. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $132 million and a corresponding reduction of income tax expense. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for the Unit Power Sales Agreement and various intercompany wholesale electric contracts which resulted in a $1 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $139 million and a corresponding reduction of income tax expense. In 2018, Entergy Arkansas and Entergy Mississippi each accrued approximately $2 billion in deductible temporary differences related to mark-to-market tax accounting for the Unit Power Sales Agreement and various wholesale electric contracts. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The effective settlement of the mark-to-market tax position for Entergy Arkansas resulted in the accrual of an increase to tax expense of $40 million, which was offset by approximately $5 million of miscellaneous excess ADIT recognized as a result of the 2016-2018 IRS audit resolution. The net increase to tax expense is deferred as a regulatory asset, as discussed within the “ Regulatory and Other Matters ” section below. Restructuring of Entergy’s Non-Utility Operations Business During the 2016 to 2018 audit period, the ownership of certain of Entergy’s non-utility operations business nuclear power plants (previously reported as part of Entergy Wholesale Commodities) was restructured. Such restructuring transactions required Entergy to recognize the plants’ nuclear decommissioning liabilities for income tax purposes. The accrual of the nuclear decommissioning liabilities also required Entergy to recognize a gain for income tax purposes, a significant portion of which resulted in an increase in the tax basis of the assets. Because certain aspects of the restructuring transactions involved uncertainty, Entergy recorded a provision for uncertain tax positions. The IRS did not propose adjustments to the tax treatment of the restructuring transactions resulting in a net decrease to income tax expense of $288 million from the reversal of the provision for uncertain tax positions in fourth quarter 2023. Reduction of Net Operating Loss Carryovers The IRS audit reduced Entergy’s net operating loss carryover by $8 billion. A portion of Entergy’s audit adjustments were not offset by losses which resulted in a tax liability of $79 million, which was fully offset by prior deposits made by Entergy. Entergy received an assessment of interest in excess of prior deposits of $13 million in December 2023, and such interest was paid in January 2024. Net operating loss carryovers were reduced by $4 billion for Entergy Arkansas, $1 billion for Entergy Louisiana, $2 billion for Entergy Mississippi, $1 billion for Entergy New Orleans, and $40 million for System Energy. The IRS audit adjustments were also factored into the settle-up required under Entergy’s intercompany income tax allocation agreement, and such amounts were settled in the fourth quarter of 2023. Regulatory and Other Matters In accordance with prior regulatory agreements associated with the Entergy Louisiana and Entergy Gulf States Louisiana business combination and Entergy New Orleans restructuring and general rate-making principles, Entergy Louisiana and Entergy New Orleans, respectively, recorded a regulatory liabilit

Significant components of accumulated deferred income taxes and taxes accrued for Entergy Corporation and Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 2023 (In Thousands) Deferred tax liabilities: Plant basis differences - net ($6,451,189) ($6,192,156) Regulatory assets (1,003,045) (989,405) Nuclear decommissioning trusts/receivables (563,423) (467,267) Pension, net regulatory asset (303,007) (363,829) Combined unitary state taxes (3,600) (8,783) Power purchase agreements (89,614) (75,612) Accumulated storm damage provision — (2,474) Deferred fuel (23,305) (69,436) Other (206,648) (251,107) Total (8,643,831) (8,420,069) Deferred tax assets: Regulatory liabilities 1,394,937 1,247,530 Nuclear and other decommissioning liabilities 164,685 147,011 Pension and other post-employment benefits 22,646 116,222 Compensation 79,580 81,226 Accumulated deferred investment tax credit 52,709 55,928 Provision for allowances and contingencies 141,769 149,479 Unbilled/deferred revenues (9,960) 2,418 Net operating loss carryforwards 2,672,993 2,857,908 Capital losses and miscellaneous tax credits 111,325 107,009 Valuation allowance (338,508) (372,119) Other 212,563 220,055 Total 4,504,739 4,612,667 Non-current accrued taxes (including unrecognized tax benefits) (309,669) (422,213) Accumulated deferred income taxes and taxes accrued ($4,448,761) ($4,229,615) Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Carryover Description Carryover Amount Year(s) of expiration Federal net operating losses before 1/1/2018 $4.4 billion 2025-2037 Federal net operating losses - 1/1/2018 forward $13.9 billion N/A State net operating losses $4.3 billion 2028-2042 State net operating losses with no expiration $8.8 billion N/A Other federal and state carryforwards $134.5 million 2025-2028 Miscellaneous federal and state credits $138.8 million 2025-2044 As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes generated and reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount. Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $339 million as of December 31, 2024 and $372 million as of December 31, 2023 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. Certain accelerated tax deductions which generated taxable losses in various taxing jurisdictions, and which have a limited term carryover period, have resulted in the impairment of the realizability of such carryovers and are reflected in the valuation allowance disclosed above. Significant components of accumulated deferred income taxes and taxes accrued for the Registrant Subsidiaries as of December 31, 2024 and 2023 are as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,530,196) ($2,729,299) ($849,623) ($272,182) ($727,242) ($466,361) Regulatory assets (219,773) (497,177) (37,374) (72,389) (100,959) (75,606) Nuclear decommissioning trusts/receivables (185,725) (202,364) — — — (175,341) Pension, net regulatory asset (101,887) (84,732) (26,064) (9,687) (16,569) — Power purchase agreements 11,993 (97,846) 1,140 (12,385) (5,148) — Deferred fuel — (4,785) (17,234) (1,247) — (78) Other (24,430) (106,590) (5,231) (5,133) (4,512) (13,572) Total (2,050,018) (3,722,793) (934,386) (373,023) (854,430) (730,958) Deferred tax assets: Regulatory liabilities 310,621 678,086 53,046 89,385 37,325 229,065 Nuclear and other decommissioning liabilities 127,933 18,649 — (407) 97 17,956 Pension and other post-employment benefits (29,923) 39,379 (8,989) (19,443) (23,403) (24,642) Compensation 4,851 7,119 3,277 1,394 2,596 515 Accumulated deferred investment tax credit 6,360 26,549 3,355 4,205 1,515 10,724 Provision for allowances and contingencies 31,686 59,448 11,361 23,998 4,358 225 Unbilled/deferred revenues 3,546 (24,017) 1,274 715 7,925 — Net operating loss carryforwards 126,255 336,128 305 30,740 50 69,611 Capital losses and miscellaneous tax credits 14,489 17,029 8,206 16,220 1,273 10,788 Other 11,608 54,207 1,096 1,692 1,189 — Total 607,426 1,212,577 72,931 148,499 32,925 314,242 Non-current accrued taxes (including unrecognized tax benefits) (46,577) 32,262 (8,661) 22,983 (47,344) (35,114) Accumulated deferred income taxes and taxes accrued ($1,489,169) ($2,477,954) ($870,116) ($201,541) ($868,849) ($451,830) 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Deferred tax liabilities: Plant basis differences - net ($1,421,272) ($2,639,079) ($810,120) ($272,187) ($671,072) ($450,559) Regulatory assets (241,427) (500,395) (41,519) (23,618) (104,562) (76,522) Nuclear decommissioning trusts/receivables (154,106) (173,402) — — — (139,858) Pension, net regulatory asset (96,853) (82,305) (24,342) (9,216) (17,522) (18,895) Power purchase agreements 15,993 (112,292) 1,140 (12,516) (4,551) — Accumulated storm damage provision — — — — (1,387) — Deferred fuel — (17,065) (21,137) (1,563) (29,194) (37) Other (21,187) (126,952) (6,844) (4,270) (3,301) (9,051) Total (1,918,852) (3,651,490) (902,822) (323,370) (831,589) (694,922) Deferred tax assets: Regulatory liabilities 296,278 575,459 54,586 42,921 41,137 240,310 Nuclear and other decommissioning liabilities 118,301 9,055 — — 97 19,259 Pension and other post-employment benefits (28,868) 46,837 (10,064) (19,354) (21,977) (2,641) Compensation 4,054 6,078 3,649 1,268 2,181 406 Accumulated deferred investment tax credit 6,761 27,902 3,446 4,431 1,672 11,717 Provision for allowances and contingencies 23,956 70,297 10,072 25,846 8,659 225 Unbilled/deferred revenues 5,962 (20,375) 6,194 1,045 8,365 — Net operating loss carryforwards 94,321 459,553 8,375 26,227 61 35,089 Capital losses and miscellaneous tax credits 7,137 13,073 7,613 15,684 1,655 13,211 Other 17,072 52,438 1,556 (235) 1,740 — Total 544,974 1,240,317 85,427 97,833 43,590 317,576 Non-current accrued taxes (including unrecognized tax benefits) (63,175) 19,731 (4,349) 29,922 (26,906) (28,398) Accumulated deferred income taxes and taxes accrued ($1,437,053) ($2,391,442) ($821,744) ($195,615) ($814,905) ($405,744) The Registrant Subsidiaries’ estimated tax attributes carryovers and their expiration dates as of December 31, 2024 are as follows: Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy Federal net operating losses before 1/1/2018 $— million $812.8 million $— million $82.6 million $— million $— million Year(s) of expiration N/A 2035-2037 N/A 2037 N/A N/A Federal net operating losses - 1/1/2018 forward $576 million $2.6 billion $— million $26.4 million $1.5 billion $264.7 million Year(s) of expiration N/A N/A N/A N/A N/A N/A State net operating losses $597.4 million $5.8 billion $7.1 million $336.6 million $1 million $370.1 million Year(s) of expiration 2028-2032 N/A 2039-2042 N/A 2028 2040-2044 Misc. federal credits $12.9 million $21 million $4.9 million $16.7 million $0.8 million $5.7 million Year(s) of expiration 2038-2044 2035-2044 2038-2044 2037-2044 2039-2044 2029-2044 State credits $— million $1.1 million $8.3 million $— million $1.3 million $17 million Year(s) of expiration N/A N/A 2025-2028 N/A 2027-2033 2025-2028 Unrecognized tax benefits Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements. If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded. A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows: 2024 2023 2022 (In Thousands) Gross balance at January 1 $2,439,910 $6,393,599 $5,759,968 Additions based on tax positions related to the current year 12,731 332,884 792,134 Additions for tax positions of prior years 21,149 194,894 37,259 Reductions for tax positions of prior years (a) (85,715) (1,300,381) (195,762) Settlements (a) (33,208) (3,181,086) — Gross balance at December 31 2,354,867 2,439,910 6,393,599 Offsets to gross unrecognized tax benefits: Loss and tax credit carryovers (2,079,778) (2,160,484) (5,566,212) Cash paid to taxing authorities (27,000) — (82,000) Unrecognized tax benefits net of unused tax attributes and payments (b) $248,089 $279,426 $745,387 (a) Amounts in 2023 are primarily related to the resolution of the 2016-2018 IRS audit as discussed in “ Income Tax Audits - 2016-2018 IRS Audit ” below. Amounts in 2024 are primarily related to the resolution of 2014-2018 Arkansas tax examination as discussed in “ Income Tax Audits - State Income Tax Audits ” below. (b) Potential tax liability above what is payable on tax returns. The balances of unrecognized tax benefits include $1,900 million, $1,899 million, and $3,254 million as of December 31, 2024, 2023, and 2022, respectively, which, if recognized, would lower the effective income tax rates. Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $455 million, $541 million, and $3,140 million as of December 31, 2024, 2023, and 2022, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense. Entergy’s December 31, 2024, 2023, and 2022 accrued balance for the possible payment of interest is approximately $32 million, $39 million, and $50 million, respectively. Interest (net-of-tax) of ($7) million, ($11) million, and $8 million was recorded in 2024, 2023, and 2022, respectively.

The Registrant Subsidiaries’ balances of unrecognized tax benefits included amounts which, if recognized, would have reduced income tax expense as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $32.6 $57.2 $377.9 Entergy Louisiana $868.2 $862.5 $720.8 Entergy Mississippi $1.3 $1.0 $151.2 Entergy New Orleans $18.3 $18.2 $310.7 Entergy Texas $50.3 $2.9 $3.3 System Energy $4.0 $3.1 $2.5 Accrued balances for the possible payment of interest related to unrecognized tax benefits for the Registrant Subsidiaries are as follows: December 31, 2024 2023 2022 (In Millions) Entergy Arkansas $8.4 $7.8 $4.3 Entergy Louisiana $5.1 $1.5 $4.1 Entergy Mississippi $3.2 $2.1 $3.1 Entergy New Orleans $0.6 $0.6 $6.4 Entergy Texas $0.5 $— $1.1 System Energy $2.9 $1.9 $1.9 The Registrant Subsidiaries record interest and penalties related to unrecognized tax benefits in income tax expense. No penalties were recorded in 2024, 2023, and 2022. Interest (net-of-tax) was recorded as follows: 2024 2023 2022 (In Millions) Entergy Arkansas $0.6 $3.5 $1.6 Entergy Louisiana $3.6 ($2.6) $0.4 Entergy Mississippi $1.1 ($1.0) $0.7 Entergy New Orleans $— ($5.8) $1.2 Entergy Texas $0.5 ($1.1) $— System Energy $1.0 $— ($10.2) Income Tax Audits Entergy and its subsidiaries file U.S. federal and various state income tax returns. IRS examinations are complete for years before 2019. All state taxing authorities’ examinations are complete for years before 2016. Entergy regularly defends its positions and works with the IRS to resolve audits. The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months. 2016-2018 IRS Audit The IRS completed its examination of the 2016 through 2018 tax years and issued a Revenue Agent Report (RAR) for each federal filer under audit in November 2023. Entergy agreed to all adjustments contained in the RARs. Entergy and the Registrant Subsidiaries recorded all the material effects resulting from the RARs in the fourth quarter of 2023. Utility Restructurings In 2017, Entergy New Orleans undertook an internal restructuring, and in 2018, Entergy Arkansas and Entergy Mississippi also participated in internal restructurings under which these three Utility operating companies joined Entergy Louisiana as wholly-owned subsidiaries of Entergy Utility Holding Company, LLC. The change in ownership required Entergy to recognize Entergy Arkansas’s nuclear decommissioning liabilities for income tax purposes, which resulted in recognition of a gain for income tax purposes and a corresponding increase in the tax basis of assets, in accordance with the Internal Revenue Code and Treasury Regulations. Entergy determined that there was uncertainty regarding the treatment of certain aspects of the restructurings and recorded provisions for uncertain tax positions which are now considered to be effectively settled in accordance with accounting standards. The reversal of such provisions for uncertain tax positions results in a reduction of income tax expense of $156 million for Entergy Arkansas, $1 million for Entergy Mississippi, and $6 million for Entergy New Orleans. The IRS also required Entergy New Orleans to reverse a tax gain associated with the 2017 restructuring that had been previously recognized, allowing Entergy New Orleans to reduce its tax expense by $39 million. After the restructuring, Entergy Arkansas adopted a new method of accounting for income tax purposes in which its nuclear decommissioning costs are treated as production costs of electricity includable in cost of goods sold, which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return that was treated as an unrecognized tax benefit. In conjunction with the audit, Entergy agreed with the IRS adjustments concerning the nuclear decommissioning tax position allowing Entergy Arkansas to include $102 million of its decommissioning liability in cost of goods sold. Mark-to-Market Method of Accounting In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement as well as other intercompany power purchase agreements. The election resulted in a $2 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with the Vidalia contract and various other third-party and intercompany wholesale electric power purchase and sale agreements. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $132 million and a corresponding reduction of income tax expense. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for the Unit Power Sales Agreement and various intercompany wholesale electric contracts which resulted in a $1 billion deductible temporary difference. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The net allowance resulted in a reversal of a provision for uncertain tax positions of $139 million and a corresponding reduction of income tax expense. In 2018, Entergy Arkansas and Entergy Mississippi each accrued approximately $2 billion in deductible temporary differences related to mark-to-market tax accounting for the Unit Power Sales Agreement and various wholesale electric contracts. The IRS allowed the mark-to-market tax method of accounting associated with various intercompany and third-party wholesale electric contracts. The IRS disallowed the net deductions associated with the Unit Power Sales Agreement, which did not have an effect on net tax expense. The effective settlement of the mark-to-market tax position for Entergy Arkansas resulted in the accrual of an increase to tax expense of $40 million, which was offset by approximately $5 million of miscellaneous excess ADIT recognized as a result of the 2016-2018 IRS audit resolution. The net increase to tax expense is deferred as a regulatory asset, as discussed within the “ Regulatory and Other Matters ” section below. Restructuring of Entergy’s Non-Utility Operations Business During the 2016 to 2018 audit period, the ownership of certain of Entergy’s non-utility operations business nuclear power plants (previously reported as part of Entergy Wholesale Commodities) was restructured. Such restructuring transactions required Entergy to recognize the plants’ nuclear decommissioning liabilities for income tax purposes. The accrual of the nuclear decommissioning liabilities also required Entergy to recognize a gain for income tax purposes, a significant portion of which resulted in an increase in the tax basis of the assets. Because certain aspects of the restructuring transactions involved uncertainty, Entergy recorded a provision for uncertain tax positions. The IRS did not propose adjustments to the tax treatment of the restructuring transactions resulting in a net decrease to income tax expense of $288 million from the reversal of the provision for uncertain tax positions in fourth quarter 2023. Reduction of Net Operating Loss Carryovers The IRS audit reduced Entergy’s net operating loss carryover by $8 billion. A portion of Entergy’s audit adjustments were not offset by losses which resulted in a tax liability of $79 million, which was fully offset by prior deposits made by Entergy. Entergy received an assessment of interest in excess of prior deposits of $13 million in December 2023, and such interest was paid in January 2024. Net operating loss carryovers were reduced by $4 billion for Entergy Arkansas, $1 billion for Entergy Louisiana, $2 billion for Entergy Mississippi, $1 billion for Entergy New Orleans, and $40 million for System Energy. The IRS audit adjustments were also factored into the settle-up required under Entergy’s intercompany income tax allocation agreement, and such amounts were settled in the fourth quarter of 2023. Regulatory and Other Matters In accordance with prior regulatory agreements associated with the Entergy Louisiana and Entergy Gulf States Louisiana business combination and Entergy New Orleans restructuring and general rate-making principles, Entergy Louisiana and Entergy New Orleans, respectively, recorded a regulatory liabilit

Grand Gulf Sale-Leaseback Transactions In 1988, in two separate but substantially identical transactions, System Energy sold and leased back undivided ownership interests in Grand Gulf for the aggregate sum of $500 million. The initial term of the leases expired in July 2015. System Energy renewed the leases in December 2013 for fair market value with renewal terms expiring in July 2036. At the end of the new lease renewal terms, System Energy has the option to repurchase the leased interests in Grand Gulf or renew the leases at fair market value. In the event that System Energy does not renew or purchase the interests, System Energy would surrender such interests and their associated entitlement of Grand Gulf’s capacity and energy. System Energy is required to report the sale-leaseback as a financing transaction in its financial statements. As such, it has recognized debt for the lease obligation and retained the portion of the plant subject to the sale-leaseback on its balance sheet. For financial reporting purposes, System Energy has recognized interest expense on the debt balance and depreciation on the applicable plant balance. The lease payments are recognized as principal and interest payments on the debt balance.

Grand Gulf Sale-Leaseback Transactions In 1988, in two separate but substantially identical transactions, System Energy sold and leased back undivided ownership interests in Grand Gulf for the aggregate sum of $500 million. The initial term of the leases expired in July 2015. System Energy renewed the leases in December 2013 for fair market value with renewal terms expiring in July 2036. At the end of the new lease renewal terms, System Energy has the option to repurchase the leased interests in Grand Gulf or renew the leases at fair market value. In the event that System Energy does not renew or purchase the interests, System Energy would surrender such interests and their associated entitlement of Grand Gulf’s capacity and energy. System Energy is required to report the sale-leaseback as a financing transaction in its financial statements. As such, it has recognized debt for the lease obligation and retained the portion of the plant subject to the sale-leaseback on its balance sheet.

Grand Gulf Sale-Leaseback Transactions In 1988, in two separate but substantially identical transactions, System Energy sold and leased back undivided ownership interests in Grand Gulf for the aggregate sum of $500 million. The initial term of the leases expired in July 2015. System Energy renewed the leases in December 2013 for fair market value with renewal terms expiring in July 2036. At the end of the new lease renewal terms, System Energy has the option to repurchase the leased interests in Grand Gulf or renew the leases at fair market value. In the event that System Energy does not renew or purchase the interests, System Energy would surrender such interests and their associated entitlement of Grand Gulf’s capacity and energy. System Energy is required to report the sale-leaseback as a financing transaction in its financial statements. As such, it has recognized debt for the lease obligation and retained the portion of the plant subject to the sale-leaseback on its balance sheet.

Grand Gulf Sale-Leaseback Transactions In 1988, in two separate but substantially identical transactions, System Energy sold and leased back undivided ownership interests in Grand Gulf for the aggregate sum of $500 million. The initial term of the leases expired in July 2015. System Energy renewed the leases in December 2013 for fair market value with renewal terms expiring in July 2036. At the end of the new lease renewal terms, System Energy has the option to repurchase the leased interests in Grand Gulf or renew the leases at fair market value. In the event that System Energy does not renew or purchase the interests, System Energy would surrender such interests and their associated entitlement of Grand Gulf’s capacity and energy. System Energy is required to report the sale-leaseback as a financing transaction in its financial statements. As such, it has recognized debt for the lease obligation and retained the portion of the plant subject to the sale-leaseback on its balance sheet.

Grand Gulf Sale-Leaseback Transactions In 1988, in two separate but substantially identical transactions, System Energy sold and leased back undivided ownership interests in Grand Gulf for the aggregate sum of $500 million. The initial term of the leases expired in July 2015. System Energy renewed the leases in December 2013 for fair market value with renewal terms expiring in July 2036. At the end of the new lease renewal terms, System Energy has the option to repurchase the leased interests in Grand Gulf or renew the leases at fair market value. In the event that System Energy does not renew or purchase the interests, System Energy would surrender such interests and their associated entitlement of Grand Gulf’s capacity and energy. System Energy is required to report the sale-leaseback as a financing transaction in its financial statements. As such, it has recognized debt for the lease obligation and retained the portion of the plant subject to the sale-leaseback on its balance sheet.

Grand Gulf Sale-Leaseback Transactions In 1988, in two separate but substantially identical transactions, System Energy sold and leased back undivided ownership interests in Grand Gulf for the aggregate sum of $500 million. The initial term of the leases expired in July 2015. System Energy renewed the leases in December 2013 for fair market value with renewal terms expiring in July 2036. At the end of the new lease renewal terms, System Energy has the option to repurchase the leased interests in Grand Gulf or renew the leases at fair market value. In the event that System Energy does not renew or purchase the interests, System Energy would surrender such interests and their associated entitlement of Grand Gulf’s capacity and energy. System Energy is required to report the sale-leaseback as a financing transaction in its financial statements. As such, it has recognized debt for the lease obligation and retained the portion of the plant subject to the sale-leaseback on its balance sheet.

Presentation of Preferred Stock without Sinking Fund Accounting standards regarding noncontrolling interests and the classification and measurement of redeemable securities require the classification of preferred securities between liabilities and shareholders’ equity on the balance sheet if the holders of those securities have protective rights that allow them to gain control of the board of directors in certain circumstances. These rights would have the effect of giving the holders the ability to potentially redeem their securities, even if the likelihood of occurrence of these circumstances is considered remote. The outstanding preferred stock of Entergy Texas has protective rights with respect to unpaid dividends but provides for the election of board members that would not constitute a majority of the board, and the preferred stock of Entergy Texas is therefore classified as a component of equity. The outstanding preferred securities of Entergy Utility Holding Company, LLC (a Utility subsidiary) and Entergy Finance Holding, Inc. (an Entergy subsidiary in the non-utility operations business), in each case, whose preferred holders have protective rights, are presented between liabilities and equity on Entergy’s consolidated balance sheets. The preferred dividends or distributions paid by all subsidiaries are reflected for all periods presented outside of consolidated net income.

The calculation of diluted earnings per share excluded 1,857,250 stock options outstanding in 2024, 2,359,923 stock options outstanding in 2023, and 1,862,906 stock options outstanding in 2022 because their effect would have been antidilutive. Until settlement of the forward sale agreements discussed below in “ Equity Distribution Program ”, earnings per share dilution resulting from the agreements, if any, is determined under the treasury stock method. Share dilution occurs when the average market price of Entergy Corporation’s common stock is higher than the average forward sales price. The calculation of diluted earnings per share excluded 2,373,682 shares in 2024 and 3,525,418 shares in 2023 under forward sale agreements outstanding because their effect would have been antidilutive. There were no forward sale agreements outstanding as of December 31, 2022 . Common stock and treasury stock shares activity for Entergy for 2024, 2023, and 2022 is as follows: 2024 2023 2022 Common Treasury Shares Common Treasury Shares Common Treasury Shares Beginning Balance, January 1 561,950,696 136,253,556 559,307,858 136,954,858 543,931,020 138,624,652 Issuances: Equity Distribution Program — — 2,642,838 — 15,376,838 — Employee Stock-Based Compensation Plans — (3,855,200) — (673,242) — (1,636,732) Directors’ Plan — (28,076) — (28,060) — (33,062) Ending Balance, December 31 561,950,696 132,370,280 561,950,696 136,253,556 559,307,858 136,954,858 Entergy Corporation reissues treasury shares to meet the requirements of the Stock Plan for Outside Directors (Directors’ Plan), the three equity plans of Entergy Corporation and Subsidiaries, and certain other stock benefit plans. The Directors’ Plan awards to non-employee directors a portion of their compensation in the form of a fixed dollar value of shares of Entergy Corporation common stock. In October 2010 the Board granted authority for a $500 million share repurchase program. As of December 31, 2024, $350 million of authority remains under the $500 million share repurchase program. Dividends declared per common share were $2.30 in 2024, $2.17 in 2023, and $2.05 in 2022. Equity Distribution Program In January 2021, Entergy Corporation entered into an equity distribution sales agreement with several counterparties establishing an at the market equity distribution program, pursuant to which Entergy Corporation may offer and sell from time to time shares of its common stock. The sales agreement provides that, in addition to the issuance and sale of shares of Entergy Corporation common stock, Entergy Corporation may enter into forward sale agreements for the sale of its common stock. In May 2024, Entergy Corporation entered into an amendment to the equity distribution sales agreement for its at the market equity distribution program wherein it increased by an additional $1 billion the aggregate gross sales price authorized under the at the market equity distribution program and added additional agents, forward purchasers, and forward sellers. The aggregate number of shares of common stock sold under this sales agreement and under any forward sale agreement may not exceed an aggregate gross sales price of $3 billion. As of December 31, 2024, an aggregate gross sales price of approximately $2.6 billion has been sold under the at the market equity distribution program. During the years ended December 31, 2024, 2023, and 2022, there were no shares of common stock issued under the at the market equity distribution program. There were no settlements of forward sale agreements for the year ended December 31, 2024. During the years ended December 31, 2023 and 2022, Entergy Corporation physically settled its obligations under the following forward sale agreements: Effective Date of Forward Sale Agreements Shares of Common Stock Issued Gross Sales Price Forward Sellers Fees Forward Sale Price per Share Cash Proceeds at Settlement (Dollars In Thousands, Except Per Share Data) Forward sale agreements settled in November 2022: June 2021 833,706 $45,000 $450 August 2021 3,385,110 $190,074 $1,901 September 2021 501,486 $25,419 $254 March 2022 3,076,020 $167,997 $1,680 June 2022 4,248,172 $250,899 $2,509 September 2022 3,332,344 $194,231 $1,942 Total 15,376,838 $56.25 $853,257 Forward sale agreements settled in November 2023: June 2023 205,990 $10,524 $105 June 2023 730,614 $37,375 $374 Total 936,604 $50.69 $47,786 Forward sale agreements settled in December 2023: November 2023 1,706,234 $84,000 $840 Total 1,706,234 $48.74 $83,312 Entergy Corporation incurred an aggregate amount of approximately $0.7 million of general issuance costs associated with the November 2022 settlement and approximately $0.4 million of general issuance costs associated with the November 2023 and December 2023 settlements. Entergy Corporation used the net proceeds for general corporate purposes, which included repayment of commercial paper, outstanding loans under Entergy Corporation’s revolving credit facility, and other debt. The following forward sale agreements entered into by Entergy Corporation remain outstanding as of December 31, 2024: Effective Date Shares of Common Stock per Forward Sale Agreements Maturity Date Forward Sale Price per Share (a) Gross Sales Price Forward Sellers Fees (Dollars In Thousands, Except Per Share Data) December 2023 5,506,492 May 2025 $50.56 $280,459 $2,805 March 2024 569,844 May 2025 $50.91 $29,318 $293 March 2024 2,320,830 May 2025 $50.73 $119,153 $1,192 May 2024 2,556,832 July 2025 $55.38 $142,387 $1,424 May 2024 2,466,470 July 2025 $54.05 $134,396 $1,344 June 2024 2,140,006 July 2025 $52.94 $114,540 $1,145 August 2024 2,225,832 October 2025 $57.67 $130,393 $1,304 August 2024 3,466,772 October 2025 $58.84 $205,454 $2,055 September 2024 3,069,070 October 2025 $60.14 $186,266 $1,863 September 2024 888,756 October 2025 $64.22 $57,702 $577 (a) Forward prices were updated with the counterparties as of December 13, 2024 in response to the stock split which was deemed an adjustment event. No amounts are recorded on Entergy’s balance sheet with respect to the equity offerings until settlements of the equity forward sale agreements occur. The forward sale agreements require Entergy Corporation to, at its election prior to the maturity date, either (i) physically settle the transactions by issuing the total shares of common stock per the respective forward sale agreement to the forward counterparties in exchange for net proceeds at the then-applicable forward sale price specified by the respective agreement (initial forward sale price) or (ii) net settle the transactions in whole or in part through the delivery or receipt of cash or shares. Each forward sale price is subject to adjustment on a daily basis based on a floating interest rate factor and will decrease by other fixed amounts specified in the respective agreement. In connection with the forward sale agreements, the forward seller, or its affiliates, borrowed from third parties and sold shares of Entergy Corporation’s common stock (gross sales price). In connection with the sale of these shares, Entergy Corporation paid the forward seller fees and these fees have not been deducted from the gross sales prices. Entergy Corporation did not receive any proceeds from such sales of borrowed shares. Retained Earnings and Dividends Entergy Corporation received dividend payments and distributions from subsidiaries totaling $484 million in 2024, $189 million in 2023, and $301 million in 2022.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended
	Dec. 31, 2024
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition. Entergy discusses regulatory proceedings in Note 2 to the financial statements and discusses tax proceedings in Note 3 to the financial statements. Vidalia Purchased Power Agreement Entergy Louisiana has an agreement extending through the year 2031 to purchase energy generated by a hydroelectric facility known as the Vidalia project. Entergy Louisiana made payments under the contract of approximately $116.8 million in 2024, $100.4 million in 2023, and $117.2 million in 2022. If the maximum percentage (94%) of the energy is made available to Entergy Louisiana, current production projections would require estimated payments of approximately $121.7 million in 2025 and a total of $730.3 million for the years 2026 through 2031. Entergy Louisiana currently recovers the costs of the purchased energy through its fuel adjustment clause. In an LPSC-approved settlement related to tax benefits from the tax treatment of the Vidalia contract, Entergy Louisiana agreed to credit rates by $11 million each year for up to 10 years, beginning in October 2002. In October 2011 the LPSC approved a settlement under which Entergy Louisiana agreed to provide credits to customers by crediting billings an additional $20.235 million per year for 15 years beginning January 2012. Entergy Louisiana recorded a regulatory charge and a corresponding regulatory liability to reflect this obligation. The settlement agreement allowed for an adjustment to the credits if, among other things, there was a change in the applicable federal or state income tax rate. As a result of the enactment of the Tax Cuts and Jobs Act, in December 2017, and the lowering of the federal corporate income tax rate from 35% to 21%, the Vidalia purchased power regulatory liability was reduced by $30.5 million, with a corresponding increase to Other regulatory credits on the income statement. See Note 3 to the financial statements for discussion of the effects of the Tax Cuts and Jobs Act and discussion of the resolution of the 2016-2018 IRS audit, which included the tax treatment of the Vidalia contract. ANO Damage, Outage, and NRC Reviews In March 2013, during a scheduled refueling outage at ANO 1, a contractor-owned and operated heavy-lifting apparatus collapsed while moving the generator stator out of the turbine building. The collapse resulted in the death of an ironworker and injuries to several other contract workers, caused ANO 2 to shut down, and damaged the ANO turbine building. The total cost of assessment, restoration of off-site power, site restoration, debris removal, and replacement of damaged property and equipment was approximately $95 million. Entergy Arkansas pursued its options for recovering damages that resulted from the stator drop, including its insurance coverage and legal action. Entergy Arkansas collected $50 million in 2014 from Nuclear Electric Insurance Limited (NEIL), a mutual insurance company that provides property damage coverage to the members’ nuclear generating plants. Entergy Arkansas also collected a total of $21 million in 2018 as a result of stator-related settlements. In addition, Entergy Arkansas incurred replacement power costs for ANO 2 power during its outage and incurred incremental replacement power costs for ANO 1 power because the outage extended beyond the originally-planned duration of the refueling outage. In February 2014 the APSC authorized Entergy Arkansas to retain $65.9 million in its deferred fuel balance with recovery to be reviewed in a later period after more information regarding various claims associated with the ANO stator incident was available. In March 2015, after several NRC inspections and regulatory conferences, arising from the stator incident, the NRC placed ANO into the “multiple/repetitive degraded cornerstone column,” or Column 4, of the NRC’s Reactor Oversight Process Action Matrix. Entergy Arkansas incurred incremental costs of approximately $53 million in 2015 to prepare for the NRC inspections that began in early 2016 in order to address the issues required to move ANO back to “licensee response” or Column 1 of the NRC’s Reactor Oversight Process Action Matrix. Excluding remediation and response costs that resulted from the additional NRC inspection activities, Entergy Arkansas incurred approximately $44 million in 2016 and $7 million in 2017 in support of NRC inspection activities and to implement Entergy Arkansas’s performance improvement initiatives developed in 2015. In June 2018 the NRC moved ANO 1 and 2 into the “licensee response column,” or Column 1, of the NRC’s Reactor Oversight Process Action Matrix. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the identified costs resulting from the ANO stator incident, specifically all incremental fuel and purchased energy expense, capital and incremental non-fuel operations and maintenance costs, and costs of any judgment that may be rendered against Entergy Arkansas in civil litigation that is not covered by insurance. As a result, in third quarter 2023, Entergy Arkansas recorded write-offs of its regulatory asset for deferred fuel of $68.9 million, which includes interest, and the undepreciated balance of $9.5 million in capital costs related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. Spent Nuclear Fuel Litigation Under the Nuclear Waste Policy Act of 1982, the DOE is required, for a specified fee, to construct storage facilities for, and to dispose of, all spent nuclear fuel and other high-level radioactive waste generated by domestic nuclear power reactors. Entergy’s nuclear owner/licensee subsidiaries have been charged fees for the estimated future disposal costs of spent nuclear fuel in accordance with the Nuclear Waste Policy Act of 1982. The affected Entergy companies entered into contracts with the DOE, whereby the DOE is to furnish disposal services at a cost of one mill per net kWh generated and sold after April 7, 1983, plus a one-time fee for generation prior to that date. Entergy considers all costs incurred for the disposal of spent nuclear fuel, except accrued interest, to be proper components of nuclear fuel expense. Provisions to recover such costs have been or will be made in applications to regulatory authorities for the Utility plants. Following the defunding of the Yucca Mountain spent fuel repository program, the National Association of Regulatory Utility Commissioners and others sued the government seeking cessation of collection of the one mill per net kWh generated and sold after April 7, 1983 fee. In November 2013 the D.C. Circuit ordered the DOE to submit a proposal to Congress to reset the fee to zero until the DOE complies with the Nuclear Waste Policy Act or Congress enacts an alternative waste disposal plan. In January 2014 the DOE submitted the proposal to Congress under protest, and also filed a petition for rehearing with the D.C. Circuit. The petition for rehearing was denied. The zero spent fuel fee went into effect prospectively in May 2014. Because the DOE has not begun accepting spent fuel, it is in non-compliance with the Nuclear Waste Policy Act of 1982 and is in partial breach of its spent fuel disposal contracts. As a result of the DOE’s failure to begin disposal of spent nuclear fuel in 1998 pursuant to the Nuclear Waste Policy Act of 1982 and the spent fuel disposal contracts, Entergy’s nuclear owner/licensee subsidiaries have incurred and will continue to incur damages. Beginning in November 2003 these subsidiaries have pursued litigation to recover the damages caused by the DOE’s delay in performance. Following are details of final judgments recorded by Entergy in 2022, 2023, and 2024 related to Entergy’s nuclear owner/licensee subsidiaries’ litigation with the DOE. In October 2021 the U.S. Court of Federal Claims issued a final judgment in the amount of $83 million in favor of Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC against the DOE in the Indian Point 2 third round and Indian Point 3 second round combined damages case. Entergy received payment from the U.S. Treasury in January 2022. The effect in 2021 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $32 million related to costs previously recorded as plant, $47 million related to costs previously recorded as other operation and maintenance expenses, and $4 million related to costs previously recorded as taxes other than income taxes. In March 2023 the DOE submitted an offer of judgment to resolve claims in the fourth round ANO damages case. The $41 million offer was accepted by Entergy Arkansas, and the U.S. Court of Federal Claims issued a judgment in that amount in favor of Entergy Arkansas and against the DOE. Entergy Arkansas received payment from the U.S. Treasury in April 2023. The effects of recording the judgment were reductions to plant, nuclear fuel expense, other operation and maintenance expenses, materials and supplies, and taxes other than income taxes. The ANO damages awarded included $18 million related to costs previously recorded as plant, $10 million related to costs previously recorded as other operation and maintenance expenses, $8 million related to costs previously recorded as nuclear fuel expense, $3 million related to costs previously recorded as materials and supplies, and $2 million related to costs previously recorded as taxes other than income taxes. In July 2023 the DOE submitted an offer of judgment to resolve claims in the Indian Point 2 fourth round and Indian Point 3 third round combined damages case. The $59 million offer was accepted by Entergy and Holtec International, as the current owner. The U.S. Court of Federal Claims issued a final judgment in that amount in favor of Holtec Indian Point 2, LLC and Holtec Indian Point 3, LLC (previously Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC) and against the DOE. Holtec received payment from the U.S. Treasury in July 2023. Consistent with certain terms agreed upon in connection with the sale of Indian Point Energy Center in May 2021, Holtec transferred $40 million to Entergy for its pro-rata share of the litigation proceeds in August 2023. The remainder of the judgment was retained by Holtec. The effect of recording Entergy’s pro-rata share of the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Entergy’s pro-rata share of the damages awarded included $18 million related to costs previously recorded as spending on the asset retirement obligation, $15 million related to costs previously recorded as other operation and maintenance expenses, $6 million related to costs previously recorded as plant, and $1 million related to costs previously recorded as taxes other than income taxes. In August 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $177 million in favor of Northstar Vermont Yankee, LLC (previously Entergy Nuclear Vermont Yankee) and against the DOE in the final round Vermont Yankee damages case. Northstar, as the current owner, received payment from the U.S. Treasury in November 2024 and subsequently transferred $127 million of the litigation proceeds to Entergy per the terms of the agreement for the disposition of Vermont Yankee, which included $107 million for independent spent fuel storage installation expansion, and related to a long-term note receivable issued to Entergy at the time of the disposition of Vermont Yankee, and $20 million for costs related to independent spent fuel storage installation operations, both as required by the disposition documents. Northstar retained $10 million of the litigation proceeds, and the remaining $40 million of the total litigation proceeds was placed by Northstar into an escrow account and is expected to be transferred to Entergy upon the satisfaction of certain agreed upon conditions. The effect of recording Entergy’s share of the judgment was a reduction of $82 million in principle and $25 million in accrued interest on the long-term note receivable and a reduction to asset write-offs, impairments, and related charges (credits) of $20 million related to costs previously recorded as spending on the asset retirement obligation. In October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Payment to Holtec, as the current owner, from the U.S. Treasury is expected in first quarter 2025, at which time Holtec is expected to transfer the $7 million judgment to Entergy. The effect of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Management cannot predict the timing or amount of any potential recoveries on other claims filed by Entergy subsidiaries and cannot predict the timing of any eventual receipt from the DOE of the U.S. Court of Federal Claims damage awards. Nuclear Insurance Third Party Liability Insurance The Price-Anderson Act requires that reactor licensees purchase insurance and participate in a secondary insurance pool that provides insurance coverage for the public in the event of a nuclear power plant accident. The costs of this insurance are borne by the nuclear power industry. Congress amended and renewed the Price-Anderson Act in 2024 for a term through 2065. The Price-Anderson Act requires nuclear power plants to show evidence of financial protection in the event of a nuclear accident. This protection must consist of two layers of coverage: 1. The primary level is i nsurance underwritten by American Nuclear Insurers (ANI) and provides public liability insurance coverage of $500 million for each operating reactor. If this amount is not sufficient to cover claims arising from an accident, the second level, Secondary Financial Protection, applies. 2. Secondary Financial Protection: Curr ently, 95 nuclear reactors participate in the Secondary Financial Protection program, which provides approximately $15.8 billion in secondary layer insurance coverage to compensate the public in the event of a nuclear power reactor accident. The Price-Anderson Act provides that all potential liability for a nuclear accident is limited to the amounts of insurance coverage available under the primary and secondary layers. Within the Secondary Financial Protection program, each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident or fault, up to a maxi mum of approximately $165.9 million per reactor per incident (Entergy’s maximum total contingent obligation per incident is $829.6 million). This retrospective premium is assessable at approximately $24.7 million per year per incident per nuclear power reactor. 3. Total insurance coverage available is approximately $16.3 billion, among the primary ANI coverage and the Secondary Financial Protection program, to respond to a nuclear power plant accident that causes third-party damages (e.g., off-site property and environmental damage, off-site bodily injury, and on-site third-party bodily injury (i.e., contractors)). These coverages also respond to an accident caused by terrorism. Entergy Arkansas and Entergy Louisiana each have two licensed reactors. System Energy has one licensed reactor (10% of Grand Gulf is owned by a non-affiliated company (Cooperative Energy) that would share on a pro-rata basis in any retrospective premium assessment to System Energy under the Price-Anderson Act). Property Insurance Entergy’s nuclear owner/licensee subsidiaries are members of NEIL, a mutual insurance company that provides property damage coverage, including decontamination and reactor stabilization, to the members’ nuclear generating plants. The property damage insurance limits procured by Entergy for its nuclear plants are in compliance with the financial protection requirements of the NRC. These coverage limits, deductibles, and weekly indemnity periods are subject to change based on results of NEIL loss control inspections. The nuclear plants’ (ANO 1 and 2, Grand Gulf, River Bend, and Waterford 3) property damage insurance limits are $1.06 billion per occurrence at each plant. The property deductible is $20 million per site at the nuclear plants, except for earth movement, flood, and windstorm. Property damage from earth movement is excluded from the first $500 million in coverage for all nuclear plants. Property damage from flood is excluded from the first $500 million in coverage at ANO 1 and 2 and Grand Gulf. Property damage from flood for Waterford 3 and River Bend includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a maximum deductible of $50 million. Property damage from a windstorm for all of the nuclear plants includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a total maximum deductible of $50 million. In addition, Waterford 3 and Entergy’s portion of Grand Gulf are also covered under NEIL’s Accidental Outage Coverage program. Accidental outage coverage provides indemnification for the actual cost incurred in the event of an unplanned outage resulting from property damage covered under the NEIL Primary Property Insurance policy, subject to a deductible period. The indemnification is based on market power prices at the time of the loss, actual costs incurred during the outage, and the respective limits of each nuclear plant. After the deductible period has passed, weekly indemnities for an unplanned nuclear or non-nuclear outage, covered under NEIL’s Accidental Outage Coverage program, would be paid according to the amounts listed below: • 100% of the weekly indemnity for each week for the initial payment period of 52 weeks for nuclear and non-nuclear loss; then • 80% of the weekly indemnity for each week for the final payment period of 110 weeks for nuclear loss only; or • 60% of the weekly indemnity for each week for the final payment period of 52 weeks for non-nuclear loss only. Under the property damage and accidental outage insurance programs, all NEIL insured plants could be subject to assessments should losses exceed the accumulated funds available from NEIL. The assessments are subject to change based on results of NEIL underwriting. The current maximum amounts of such possible assessments per occurrence are as follows: Assessments (In Millions) Entergy Arkansas $20.0 Entergy Louisiana $37.6 Entergy Mississippi $0.1 Entergy New Orleans $0.1 Entergy Texas N/A System Energy $14.4 NRC regulations provide that the proceeds of this insurance must be used, first, to render the reactor safe and stable, and second, to complete decontamination operations. Only after proceeds are dedicated for such use and regulatory approval is secured would any remaining proceeds be made available for the benefit of plant owners or their creditors. In the event that one or more acts of terrorism causes property damage from a nuclear event under one or more or all nuclear insurance policies issued by NEIL (including, but not limited to, those described above) within 12 months from the date the first property damage occurs, the maximum recovery under all such nuclear insurance policies shall be an aggregate not exceedi ng $3.24 billion plus the additional amounts recovered for such losses from reinsurance, indemnity, and any other sources applicable to such losses. Non-Nuclear Property Insurance Entergy’s non-nuclear property insurance program provides coverage on a system-wide basis for Entergy’s non-nuclear assets. The insurance program provides coverage for property damage up to $400 million per occurrence in excess of a $20 million self-insured retention except for property damage caused by the following: earthquake shock, flood, and named windstorm, including associated storm surge. For earthquake shock and flood, the insurance program provides coverage up to $400 million on an annual aggregate basis in excess of a $40 million self-insured retention. For named windstorm and associated storm surge, the insurance program provides coverage up to $125 million on an annual aggregate basis in excess of a $40 million self-insured retention. The coverage provided by the insurance program for the Entergy New Orleans gas distribution system is limited to $50 million per occurrence and is subject to the same annual aggregate limits and retentions listed above for earthquake shock, flood, and named windstorm, including associated storm surge. Covered property generally includes power plants, substations, facilities, inventories, and gas distribution-related properties. Excluded property generally includes transmission and distribution lines, poles, and towers. For substations valued at $5 million or less, coverage for named windstorm and associated storm surge is excluded. This coverage is in place for Entergy Corporation, the Registrant Subsidiaries, and certain other Entergy subsidiaries. Entergy also purchases $400 million in terrorism insurance coverage for its conventional property. Employment and Labor-related Proceedings The Registrant Subsidiaries and other Entergy subsidiaries and related entities are responding to various lawsuits in both state and federal courts and to other labor-related proceedings filed by current and former employees, recognized bargaining representatives, and certain third parties. Generally, the amount of damages being sought is not specified in these proceedings. These actions may include, but are not limited to, allegations of wrongful employment actions; wage disputes and other claims under the Fair Labor Standards Act or its state counterparts; claims of race, gender, age, and disability discrimination; disputes arising under collective bargaining agreements; unfair labor practice proceedings and other administrative proceedings before the National Labor Relations Board or concerning the National Labor Relations Act; claims of retaliation; claims of harassment and hostile work environment; and claims for or regarding benefits under various Entergy Corporation-sponsored employee benefit plans. Entergy and the Registrant Subsidiaries and related entities are responding to these lawsuits and proceedings and deny liability to the claimants. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of Entergy or the Registrant Subsidiaries. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) Numerous lawsuits have been filed in state courts against primarily Entergy Louisiana and Entergy Texas by individuals alleging exposure to asbestos while working at Entergy facilities between 1955 and 1980. Entergy is being sued as a premises owner. Many other defendants are named in these lawsuits as well. Currently, there are approximately 185 lawsuits involving approximately 330 claimants. Management believes that adequate provisions have been established to cover any exposure. Additionally, negotiations continue with insurers to recover reimbursements. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of the Utility operating companies. Grand Gulf-Related Agreements Unit Power Sales Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy sells all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. Charges under this agreement are paid in consideration for the purchasing companies’ respective entitlement to receive capacity and energy and are payable irrespective of the quantity of energy delivered. Grand Gulf’s operating license currently extends through 2044. Monthly obligations are based on actual capacity and energy costs. The average monthly payments for 2024 under the agreement were approximately $16.8 million for Entergy Arkansas, $7.0 million for Entergy Louisiana, $16.4 million for Entergy Mississippi, and $8.4 million for Entergy New Orleans. See Note 2 to the financial statements for discussion of proceedings regarding the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture is being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a PPA governed by the MSS-4 replacement tariff. As discussed in Note 2 to the financial statements, in September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The MSS-4 replacement PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumes any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025. See Note 2 to the financial statements for discussion of the System Energy settlement with the LPSC. Availability Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans are individually obligated to make payments or subordinated advances to System Energy in accordance with stated percentages (Entergy Arkansas - 17.1%, Entergy Louisiana - 26.9%, Entergy Mississippi - 31.3%, and Entergy New Orleans - 24.7%) in amounts that, when added to amounts received under the Unit Power Sales Agreement or otherwise, are adequate to cover all of System Energy’s operating expenses as defined, including expenses incurred in connection with a permanent shutdown of Grand Gulf. System Energy has assigned its rights to payments and advances to certain creditors as security for certain of its debt obligations. Since commercial operation of Grand Gulf began, payments under the Unit Power Sales Agreement to System Energy have exceeded the amounts payable under the Availability Agreement and, therefore, no payments under the Availability Agreement have ever been required. However, if Entergy Arkansas or Entergy Mississippi fails to make its Unit Power Sales Agreement payments, and System Energy is unable to obtain funds from other sources, Entergy Louisiana and Entergy New Orleans could become subject to claims or demands by System Energy or certain of its creditors for payments or advances under the Availability Agreement (or the assignments thereof) equal to the difference between their required Unit Power Sales Agreement payments and their required Availability Agreement payments because their allocated shares under the Availability Agreement exceed their allocated shares under the Unit Power Sales Agreement. Under the Entergy Louisiana divestiture described in “ Unit Power Sales Agreement ” above, Entergy Mississippi assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, effective as of January 1, 2025. Reallocation Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans entered into the Reallocation Agreement relating to the sale of capacity and energy from Grand Gulf and the related costs, in which Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans agreed to assume all of Entergy Arkansas’s responsibilities and obligations with respect to Grand Gulf under the Availability Agreement. The FERC’s decision allocating a portion of Grand Gulf capacity and energy to Entergy Arkansas supersedes the Reallocation Agreement as it relates to Grand Gulf. Effective December 2024, the parties terminated the Reallocation Agreement.
Entergy Arkansas [Member]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition. Entergy discusses regulatory proceedings in Note 2 to the financial statements and discusses tax proceedings in Note 3 to the financial statements. Vidalia Purchased Power Agreement Entergy Louisiana has an agreement extending through the year 2031 to purchase energy generated by a hydroelectric facility known as the Vidalia project. Entergy Louisiana made payments under the contract of approximately $116.8 million in 2024, $100.4 million in 2023, and $117.2 million in 2022. If the maximum percentage (94%) of the energy is made available to Entergy Louisiana, current production projections would require estimated payments of approximately $121.7 million in 2025 and a total of $730.3 million for the years 2026 through 2031. Entergy Louisiana currently recovers the costs of the purchased energy through its fuel adjustment clause. In an LPSC-approved settlement related to tax benefits from the tax treatment of the Vidalia contract, Entergy Louisiana agreed to credit rates by $11 million each year for up to 10 years, beginning in October 2002. In October 2011 the LPSC approved a settlement under which Entergy Louisiana agreed to provide credits to customers by crediting billings an additional $20.235 million per year for 15 years beginning January 2012. Entergy Louisiana recorded a regulatory charge and a corresponding regulatory liability to reflect this obligation. The settlement agreement allowed for an adjustment to the credits if, among other things, there was a change in the applicable federal or state income tax rate. As a result of the enactment of the Tax Cuts and Jobs Act, in December 2017, and the lowering of the federal corporate income tax rate from 35% to 21%, the Vidalia purchased power regulatory liability was reduced by $30.5 million, with a corresponding increase to Other regulatory credits on the income statement. See Note 3 to the financial statements for discussion of the effects of the Tax Cuts and Jobs Act and discussion of the resolution of the 2016-2018 IRS audit, which included the tax treatment of the Vidalia contract. ANO Damage, Outage, and NRC Reviews In March 2013, during a scheduled refueling outage at ANO 1, a contractor-owned and operated heavy-lifting apparatus collapsed while moving the generator stator out of the turbine building. The collapse resulted in the death of an ironworker and injuries to several other contract workers, caused ANO 2 to shut down, and damaged the ANO turbine building. The total cost of assessment, restoration of off-site power, site restoration, debris removal, and replacement of damaged property and equipment was approximately $95 million. Entergy Arkansas pursued its options for recovering damages that resulted from the stator drop, including its insurance coverage and legal action. Entergy Arkansas collected $50 million in 2014 from Nuclear Electric Insurance Limited (NEIL), a mutual insurance company that provides property damage coverage to the members’ nuclear generating plants. Entergy Arkansas also collected a total of $21 million in 2018 as a result of stator-related settlements. In addition, Entergy Arkansas incurred replacement power costs for ANO 2 power during its outage and incurred incremental replacement power costs for ANO 1 power because the outage extended beyond the originally-planned duration of the refueling outage. In February 2014 the APSC authorized Entergy Arkansas to retain $65.9 million in its deferred fuel balance with recovery to be reviewed in a later period after more information regarding various claims associated with the ANO stator incident was available. In March 2015, after several NRC inspections and regulatory conferences, arising from the stator incident, the NRC placed ANO into the “multiple/repetitive degraded cornerstone column,” or Column 4, of the NRC’s Reactor Oversight Process Action Matrix. Entergy Arkansas incurred incremental costs of approximately $53 million in 2015 to prepare for the NRC inspections that began in early 2016 in order to address the issues required to move ANO back to “licensee response” or Column 1 of the NRC’s Reactor Oversight Process Action Matrix. Excluding remediation and response costs that resulted from the additional NRC inspection activities, Entergy Arkansas incurred approximately $44 million in 2016 and $7 million in 2017 in support of NRC inspection activities and to implement Entergy Arkansas’s performance improvement initiatives developed in 2015. In June 2018 the NRC moved ANO 1 and 2 into the “licensee response column,” or Column 1, of the NRC’s Reactor Oversight Process Action Matrix. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the identified costs resulting from the ANO stator incident, specifically all incremental fuel and purchased energy expense, capital and incremental non-fuel operations and maintenance costs, and costs of any judgment that may be rendered against Entergy Arkansas in civil litigation that is not covered by insurance. As a result, in third quarter 2023, Entergy Arkansas recorded write-offs of its regulatory asset for deferred fuel of $68.9 million, which includes interest, and the undepreciated balance of $9.5 million in capital costs related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. Spent Nuclear Fuel Litigation Under the Nuclear Waste Policy Act of 1982, the DOE is required, for a specified fee, to construct storage facilities for, and to dispose of, all spent nuclear fuel and other high-level radioactive waste generated by domestic nuclear power reactors. Entergy’s nuclear owner/licensee subsidiaries have been charged fees for the estimated future disposal costs of spent nuclear fuel in accordance with the Nuclear Waste Policy Act of 1982. The affected Entergy companies entered into contracts with the DOE, whereby the DOE is to furnish disposal services at a cost of one mill per net kWh generated and sold after April 7, 1983, plus a one-time fee for generation prior to that date. Entergy considers all costs incurred for the disposal of spent nuclear fuel, except accrued interest, to be proper components of nuclear fuel expense. Provisions to recover such costs have been or will be made in applications to regulatory authorities for the Utility plants. Following the defunding of the Yucca Mountain spent fuel repository program, the National Association of Regulatory Utility Commissioners and others sued the government seeking cessation of collection of the one mill per net kWh generated and sold after April 7, 1983 fee. In November 2013 the D.C. Circuit ordered the DOE to submit a proposal to Congress to reset the fee to zero until the DOE complies with the Nuclear Waste Policy Act or Congress enacts an alternative waste disposal plan. In January 2014 the DOE submitted the proposal to Congress under protest, and also filed a petition for rehearing with the D.C. Circuit. The petition for rehearing was denied. The zero spent fuel fee went into effect prospectively in May 2014. Because the DOE has not begun accepting spent fuel, it is in non-compliance with the Nuclear Waste Policy Act of 1982 and is in partial breach of its spent fuel disposal contracts. As a result of the DOE’s failure to begin disposal of spent nuclear fuel in 1998 pursuant to the Nuclear Waste Policy Act of 1982 and the spent fuel disposal contracts, Entergy’s nuclear owner/licensee subsidiaries have incurred and will continue to incur damages. Beginning in November 2003 these subsidiaries have pursued litigation to recover the damages caused by the DOE’s delay in performance. Following are details of final judgments recorded by Entergy in 2022, 2023, and 2024 related to Entergy’s nuclear owner/licensee subsidiaries’ litigation with the DOE. In October 2021 the U.S. Court of Federal Claims issued a final judgment in the amount of $83 million in favor of Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC against the DOE in the Indian Point 2 third round and Indian Point 3 second round combined damages case. Entergy received payment from the U.S. Treasury in January 2022. The effect in 2021 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $32 million related to costs previously recorded as plant, $47 million related to costs previously recorded as other operation and maintenance expenses, and $4 million related to costs previously recorded as taxes other than income taxes. In March 2023 the DOE submitted an offer of judgment to resolve claims in the fourth round ANO damages case. The $41 million offer was accepted by Entergy Arkansas, and the U.S. Court of Federal Claims issued a judgment in that amount in favor of Entergy Arkansas and against the DOE. Entergy Arkansas received payment from the U.S. Treasury in April 2023. The effects of recording the judgment were reductions to plant, nuclear fuel expense, other operation and maintenance expenses, materials and supplies, and taxes other than income taxes. The ANO damages awarded included $18 million related to costs previously recorded as plant, $10 million related to costs previously recorded as other operation and maintenance expenses, $8 million related to costs previously recorded as nuclear fuel expense, $3 million related to costs previously recorded as materials and supplies, and $2 million related to costs previously recorded as taxes other than income taxes. In July 2023 the DOE submitted an offer of judgment to resolve claims in the Indian Point 2 fourth round and Indian Point 3 third round combined damages case. The $59 million offer was accepted by Entergy and Holtec International, as the current owner. The U.S. Court of Federal Claims issued a final judgment in that amount in favor of Holtec Indian Point 2, LLC and Holtec Indian Point 3, LLC (previously Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC) and against the DOE. Holtec received payment from the U.S. Treasury in July 2023. Consistent with certain terms agreed upon in connection with the sale of Indian Point Energy Center in May 2021, Holtec transferred $40 million to Entergy for its pro-rata share of the litigation proceeds in August 2023. The remainder of the judgment was retained by Holtec. The effect of recording Entergy’s pro-rata share of the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Entergy’s pro-rata share of the damages awarded included $18 million related to costs previously recorded as spending on the asset retirement obligation, $15 million related to costs previously recorded as other operation and maintenance expenses, $6 million related to costs previously recorded as plant, and $1 million related to costs previously recorded as taxes other than income taxes. In August 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $177 million in favor of Northstar Vermont Yankee, LLC (previously Entergy Nuclear Vermont Yankee) and against the DOE in the final round Vermont Yankee damages case. Northstar, as the current owner, received payment from the U.S. Treasury in November 2024 and subsequently transferred $127 million of the litigation proceeds to Entergy per the terms of the agreement for the disposition of Vermont Yankee, which included $107 million for independent spent fuel storage installation expansion, and related to a long-term note receivable issued to Entergy at the time of the disposition of Vermont Yankee, and $20 million for costs related to independent spent fuel storage installation operations, both as required by the disposition documents. Northstar retained $10 million of the litigation proceeds, and the remaining $40 million of the total litigation proceeds was placed by Northstar into an escrow account and is expected to be transferred to Entergy upon the satisfaction of certain agreed upon conditions. The effect of recording Entergy’s share of the judgment was a reduction of $82 million in principle and $25 million in accrued interest on the long-term note receivable and a reduction to asset write-offs, impairments, and related charges (credits) of $20 million related to costs previously recorded as spending on the asset retirement obligation. In October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Payment to Holtec, as the current owner, from the U.S. Treasury is expected in first quarter 2025, at which time Holtec is expected to transfer the $7 million judgment to Entergy. The effect of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Management cannot predict the timing or amount of any potential recoveries on other claims filed by Entergy subsidiaries and cannot predict the timing of any eventual receipt from the DOE of the U.S. Court of Federal Claims damage awards. Nuclear Insurance Third Party Liability Insurance The Price-Anderson Act requires that reactor licensees purchase insurance and participate in a secondary insurance pool that provides insurance coverage for the public in the event of a nuclear power plant accident. The costs of this insurance are borne by the nuclear power industry. Congress amended and renewed the Price-Anderson Act in 2024 for a term through 2065. The Price-Anderson Act requires nuclear power plants to show evidence of financial protection in the event of a nuclear accident. This protection must consist of two layers of coverage: 1. The primary level is i nsurance underwritten by American Nuclear Insurers (ANI) and provides public liability insurance coverage of $500 million for each operating reactor. If this amount is not sufficient to cover claims arising from an accident, the second level, Secondary Financial Protection, applies. 2. Secondary Financial Protection: Curr ently, 95 nuclear reactors participate in the Secondary Financial Protection program, which provides approximately $15.8 billion in secondary layer insurance coverage to compensate the public in the event of a nuclear power reactor accident. The Price-Anderson Act provides that all potential liability for a nuclear accident is limited to the amounts of insurance coverage available under the primary and secondary layers. Within the Secondary Financial Protection program, each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident or fault, up to a maxi mum of approximately $165.9 million per reactor per incident (Entergy’s maximum total contingent obligation per incident is $829.6 million). This retrospective premium is assessable at approximately $24.7 million per year per incident per nuclear power reactor. 3. Total insurance coverage available is approximately $16.3 billion, among the primary ANI coverage and the Secondary Financial Protection program, to respond to a nuclear power plant accident that causes third-party damages (e.g., off-site property and environmental damage, off-site bodily injury, and on-site third-party bodily injury (i.e., contractors)). These coverages also respond to an accident caused by terrorism. Entergy Arkansas and Entergy Louisiana each have two licensed reactors. System Energy has one licensed reactor (10% of Grand Gulf is owned by a non-affiliated company (Cooperative Energy) that would share on a pro-rata basis in any retrospective premium assessment to System Energy under the Price-Anderson Act). Property Insurance Entergy’s nuclear owner/licensee subsidiaries are members of NEIL, a mutual insurance company that provides property damage coverage, including decontamination and reactor stabilization, to the members’ nuclear generating plants. The property damage insurance limits procured by Entergy for its nuclear plants are in compliance with the financial protection requirements of the NRC. These coverage limits, deductibles, and weekly indemnity periods are subject to change based on results of NEIL loss control inspections. The nuclear plants’ (ANO 1 and 2, Grand Gulf, River Bend, and Waterford 3) property damage insurance limits are $1.06 billion per occurrence at each plant. The property deductible is $20 million per site at the nuclear plants, except for earth movement, flood, and windstorm. Property damage from earth movement is excluded from the first $500 million in coverage for all nuclear plants. Property damage from flood is excluded from the first $500 million in coverage at ANO 1 and 2 and Grand Gulf. Property damage from flood for Waterford 3 and River Bend includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a maximum deductible of $50 million. Property damage from a windstorm for all of the nuclear plants includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a total maximum deductible of $50 million. In addition, Waterford 3 and Entergy’s portion of Grand Gulf are also covered under NEIL’s Accidental Outage Coverage program. Accidental outage coverage provides indemnification for the actual cost incurred in the event of an unplanned outage resulting from property damage covered under the NEIL Primary Property Insurance policy, subject to a deductible period. The indemnification is based on market power prices at the time of the loss, actual costs incurred during the outage, and the respective limits of each nuclear plant. After the deductible period has passed, weekly indemnities for an unplanned nuclear or non-nuclear outage, covered under NEIL’s Accidental Outage Coverage program, would be paid according to the amounts listed below: • 100% of the weekly indemnity for each week for the initial payment period of 52 weeks for nuclear and non-nuclear loss; then • 80% of the weekly indemnity for each week for the final payment period of 110 weeks for nuclear loss only; or • 60% of the weekly indemnity for each week for the final payment period of 52 weeks for non-nuclear loss only. Under the property damage and accidental outage insurance programs, all NEIL insured plants could be subject to assessments should losses exceed the accumulated funds available from NEIL. The assessments are subject to change based on results of NEIL underwriting. The current maximum amounts of such possible assessments per occurrence are as follows: Assessments (In Millions) Entergy Arkansas $20.0 Entergy Louisiana $37.6 Entergy Mississippi $0.1 Entergy New Orleans $0.1 Entergy Texas N/A System Energy $14.4 NRC regulations provide that the proceeds of this insurance must be used, first, to render the reactor safe and stable, and second, to complete decontamination operations. Only after proceeds are dedicated for such use and regulatory approval is secured would any remaining proceeds be made available for the benefit of plant owners or their creditors. In the event that one or more acts of terrorism causes property damage from a nuclear event under one or more or all nuclear insurance policies issued by NEIL (including, but not limited to, those described above) within 12 months from the date the first property damage occurs, the maximum recovery under all such nuclear insurance policies shall be an aggregate not exceedi ng $3.24 billion plus the additional amounts recovered for such losses from reinsurance, indemnity, and any other sources applicable to such losses. Non-Nuclear Property Insurance Entergy’s non-nuclear property insurance program provides coverage on a system-wide basis for Entergy’s non-nuclear assets. The insurance program provides coverage for property damage up to $400 million per occurrence in excess of a $20 million self-insured retention except for property damage caused by the following: earthquake shock, flood, and named windstorm, including associated storm surge. For earthquake shock and flood, the insurance program provides coverage up to $400 million on an annual aggregate basis in excess of a $40 million self-insured retention. For named windstorm and associated storm surge, the insurance program provides coverage up to $125 million on an annual aggregate basis in excess of a $40 million self-insured retention. The coverage provided by the insurance program for the Entergy New Orleans gas distribution system is limited to $50 million per occurrence and is subject to the same annual aggregate limits and retentions listed above for earthquake shock, flood, and named windstorm, including associated storm surge. Covered property generally includes power plants, substations, facilities, inventories, and gas distribution-related properties. Excluded property generally includes transmission and distribution lines, poles, and towers. For substations valued at $5 million or less, coverage for named windstorm and associated storm surge is excluded. This coverage is in place for Entergy Corporation, the Registrant Subsidiaries, and certain other Entergy subsidiaries. Entergy also purchases $400 million in terrorism insurance coverage for its conventional property. Employment and Labor-related Proceedings The Registrant Subsidiaries and other Entergy subsidiaries and related entities are responding to various lawsuits in both state and federal courts and to other labor-related proceedings filed by current and former employees, recognized bargaining representatives, and certain third parties. Generally, the amount of damages being sought is not specified in these proceedings. These actions may include, but are not limited to, allegations of wrongful employment actions; wage disputes and other claims under the Fair Labor Standards Act or its state counterparts; claims of race, gender, age, and disability discrimination; disputes arising under collective bargaining agreements; unfair labor practice proceedings and other administrative proceedings before the National Labor Relations Board or concerning the National Labor Relations Act; claims of retaliation; claims of harassment and hostile work environment; and claims for or regarding benefits under various Entergy Corporation-sponsored employee benefit plans. Entergy and the Registrant Subsidiaries and related entities are responding to these lawsuits and proceedings and deny liability to the claimants. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of Entergy or the Registrant Subsidiaries. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) Numerous lawsuits have been filed in state courts against primarily Entergy Louisiana and Entergy Texas by individuals alleging exposure to asbestos while working at Entergy facilities between 1955 and 1980. Entergy is being sued as a premises owner. Many other defendants are named in these lawsuits as well. Currently, there are approximately 185 lawsuits involving approximately 330 claimants. Management believes that adequate provisions have been established to cover any exposure. Additionally, negotiations continue with insurers to recover reimbursements. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of the Utility operating companies. Grand Gulf-Related Agreements Unit Power Sales Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy sells all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. Charges under this agreement are paid in consideration for the purchasing companies’ respective entitlement to receive capacity and energy and are payable irrespective of the quantity of energy delivered. Grand Gulf’s operating license currently extends through 2044. Monthly obligations are based on actual capacity and energy costs. The average monthly payments for 2024 under the agreement were approximately $16.8 million for Entergy Arkansas, $7.0 million for Entergy Louisiana, $16.4 million for Entergy Mississippi, and $8.4 million for Entergy New Orleans.

See Note 2 to the financial statements for discussion of the System Energy settlement with the LPSC. Availability Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans are individually obligated to make payments or subordinated advances to System Energy in accordance with stated percentages (Entergy Arkansas - 17.1%, Entergy Louisiana - 26.9%, Entergy Mississippi - 31.3%, and Entergy New Orleans - 24.7%) in amounts that, when added to amounts received under the Unit Power Sales Agreement or otherwise, are adequate to cover all of System Energy’s operating expenses as defined, including expenses incurred in connection with a permanent shutdown of Grand Gulf. System Energy has assigned its rights to payments and advances to certain creditors as security for certain of its debt obligations. Since commercial operation of Grand Gulf began, payments under the Unit Power Sales Agreement to System Energy have exceeded the amounts payable under the Availability Agreement and, therefore, no payments under the Availability Agreement have ever been required. However, if Entergy Arkansas or Entergy Mississippi fails to make its Unit Power Sales Agreement payments, and System Energy is unable to obtain funds from other sources, Entergy Louisiana and Entergy New Orleans could become subject to claims or demands by System Energy or certain of its creditors for payments or advances under the Availability Agreement (or the assignments thereof) equal to the difference between their required Unit Power Sales Agreement payments and their required Availability Agreement payments because their allocated shares under the Availability Agreement exceed their allocated shares under the Unit Power Sales Agreement. Under the Entergy Louisiana divestiture described in “ Unit Power Sales Agreement ” above, Entergy Mississippi assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, effective as of January 1, 2025. Reallocation Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans entered into the Reallocation Agreement relating to the sale of capacity and energy from Grand Gulf and the related costs, in which Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans agreed to assume all of Entergy Arkansas’s responsibilities and obligations with respect to Grand Gulf under the Availability Agreement. The FERC’s decision allocating a portion of Grand Gulf capacity and energy to Entergy Arkansas supersedes the Reallocation Agreement as it relates to Grand Gulf. Effective December 2024, the parties terminated the Reallocation Agreement.

Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition. Entergy discusses regulatory proceedings in Note 2 to the financial statements and discusses tax proceedings in Note 3 to the financial statements. Vidalia Purchased Power Agreement Entergy Louisiana has an agreement extending through the year 2031 to purchase energy generated by a hydroelectric facility known as the Vidalia project. Entergy Louisiana made payments under the contract of approximately $116.8 million in 2024, $100.4 million in 2023, and $117.2 million in 2022. If the maximum percentage (94%) of the energy is made available to Entergy Louisiana, current production projections would require estimated payments of approximately $121.7 million in 2025 and a total of $730.3 million for the years 2026 through 2031. Entergy Louisiana currently recovers the costs of the purchased energy through its fuel adjustment clause. In an LPSC-approved settlement related to tax benefits from the tax treatment of the Vidalia contract, Entergy Louisiana agreed to credit rates by $11 million each year for up to 10 years, beginning in October 2002. In October 2011 the LPSC approved a settlement under which Entergy Louisiana agreed to provide credits to customers by crediting billings an additional $20.235 million per year for 15 years beginning January 2012. Entergy Louisiana recorded a regulatory charge and a corresponding regulatory liability to reflect this obligation. The settlement agreement allowed for an adjustment to the credits if, among other things, there was a change in the applicable federal or state income tax rate. As a result of the enactment of the Tax Cuts and Jobs Act, in December 2017, and the lowering of the federal corporate income tax rate from 35% to 21%, the Vidalia purchased power regulatory liability was reduced by $30.5 million, with a corresponding increase to Other regulatory credits on the income statement. See Note 3 to the financial statements for discussion of the effects of the Tax Cuts and Jobs Act and discussion of the resolution of the 2016-2018 IRS audit, which included the tax treatment of the Vidalia contract. ANO Damage, Outage, and NRC Reviews In March 2013, during a scheduled refueling outage at ANO 1, a contractor-owned and operated heavy-lifting apparatus collapsed while moving the generator stator out of the turbine building. The collapse resulted in the death of an ironworker and injuries to several other contract workers, caused ANO 2 to shut down, and damaged the ANO turbine building. The total cost of assessment, restoration of off-site power, site restoration, debris removal, and replacement of damaged property and equipment was approximately $95 million. Entergy Arkansas pursued its options for recovering damages that resulted from the stator drop, including its insurance coverage and legal action. Entergy Arkansas collected $50 million in 2014 from Nuclear Electric Insurance Limited (NEIL), a mutual insurance company that provides property damage coverage to the members’ nuclear generating plants. Entergy Arkansas also collected a total of $21 million in 2018 as a result of stator-related settlements. In addition, Entergy Arkansas incurred replacement power costs for ANO 2 power during its outage and incurred incremental replacement power costs for ANO 1 power because the outage extended beyond the originally-planned duration of the refueling outage. In February 2014 the APSC authorized Entergy Arkansas to retain $65.9 million in its deferred fuel balance with recovery to be reviewed in a later period after more information regarding various claims associated with the ANO stator incident was available. In March 2015, after several NRC inspections and regulatory conferences, arising from the stator incident, the NRC placed ANO into the “multiple/repetitive degraded cornerstone column,” or Column 4, of the NRC’s Reactor Oversight Process Action Matrix. Entergy Arkansas incurred incremental costs of approximately $53 million in 2015 to prepare for the NRC inspections that began in early 2016 in order to address the issues required to move ANO back to “licensee response” or Column 1 of the NRC’s Reactor Oversight Process Action Matrix. Excluding remediation and response costs that resulted from the additional NRC inspection activities, Entergy Arkansas incurred approximately $44 million in 2016 and $7 million in 2017 in support of NRC inspection activities and to implement Entergy Arkansas’s performance improvement initiatives developed in 2015. In June 2018 the NRC moved ANO 1 and 2 into the “licensee response column,” or Column 1, of the NRC’s Reactor Oversight Process Action Matrix. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the identified costs resulting from the ANO stator incident, specifically all incremental fuel and purchased energy expense, capital and incremental non-fuel operations and maintenance costs, and costs of any judgment that may be rendered against Entergy Arkansas in civil litigation that is not covered by insurance. As a result, in third quarter 2023, Entergy Arkansas recorded write-offs of its regulatory asset for deferred fuel of $68.9 million, which includes interest, and the undepreciated balance of $9.5 million in capital costs related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. Spent Nuclear Fuel Litigation Under the Nuclear Waste Policy Act of 1982, the DOE is required, for a specified fee, to construct storage facilities for, and to dispose of, all spent nuclear fuel and other high-level radioactive waste generated by domestic nuclear power reactors. Entergy’s nuclear owner/licensee subsidiaries have been charged fees for the estimated future disposal costs of spent nuclear fuel in accordance with the Nuclear Waste Policy Act of 1982. The affected Entergy companies entered into contracts with the DOE, whereby the DOE is to furnish disposal services at a cost of one mill per net kWh generated and sold after April 7, 1983, plus a one-time fee for generation prior to that date. Entergy considers all costs incurred for the disposal of spent nuclear fuel, except accrued interest, to be proper components of nuclear fuel expense. Provisions to recover such costs have been or will be made in applications to regulatory authorities for the Utility plants. Following the defunding of the Yucca Mountain spent fuel repository program, the National Association of Regulatory Utility Commissioners and others sued the government seeking cessation of collection of the one mill per net kWh generated and sold after April 7, 1983 fee. In November 2013 the D.C. Circuit ordered the DOE to submit a proposal to Congress to reset the fee to zero until the DOE complies with the Nuclear Waste Policy Act or Congress enacts an alternative waste disposal plan. In January 2014 the DOE submitted the proposal to Congress under protest, and also filed a petition for rehearing with the D.C. Circuit. The petition for rehearing was denied. The zero spent fuel fee went into effect prospectively in May 2014. Because the DOE has not begun accepting spent fuel, it is in non-compliance with the Nuclear Waste Policy Act of 1982 and is in partial breach of its spent fuel disposal contracts. As a result of the DOE’s failure to begin disposal of spent nuclear fuel in 1998 pursuant to the Nuclear Waste Policy Act of 1982 and the spent fuel disposal contracts, Entergy’s nuclear owner/licensee subsidiaries have incurred and will continue to incur damages. Beginning in November 2003 these subsidiaries have pursued litigation to recover the damages caused by the DOE’s delay in performance. Following are details of final judgments recorded by Entergy in 2022, 2023, and 2024 related to Entergy’s nuclear owner/licensee subsidiaries’ litigation with the DOE. In October 2021 the U.S. Court of Federal Claims issued a final judgment in the amount of $83 million in favor of Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC against the DOE in the Indian Point 2 third round and Indian Point 3 second round combined damages case. Entergy received payment from the U.S. Treasury in January 2022. The effect in 2021 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $32 million related to costs previously recorded as plant, $47 million related to costs previously recorded as other operation and maintenance expenses, and $4 million related to costs previously recorded as taxes other than income taxes. In March 2023 the DOE submitted an offer of judgment to resolve claims in the fourth round ANO damages case. The $41 million offer was accepted by Entergy Arkansas, and the U.S. Court of Federal Claims issued a judgment in that amount in favor of Entergy Arkansas and against the DOE. Entergy Arkansas received payment from the U.S. Treasury in April 2023. The effects of recording the judgment were reductions to plant, nuclear fuel expense, other operation and maintenance expenses, materials and supplies, and taxes other than income taxes. The ANO damages awarded included $18 million related to costs previously recorded as plant, $10 million related to costs previously recorded as other operation and maintenance expenses, $8 million related to costs previously recorded as nuclear fuel expense, $3 million related to costs previously recorded as materials and supplies, and $2 million related to costs previously recorded as taxes other than income taxes. In July 2023 the DOE submitted an offer of judgment to resolve claims in the Indian Point 2 fourth round and Indian Point 3 third round combined damages case. The $59 million offer was accepted by Entergy and Holtec International, as the current owner. The U.S. Court of Federal Claims issued a final judgment in that amount in favor of Holtec Indian Point 2, LLC and Holtec Indian Point 3, LLC (previously Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC) and against the DOE. Holtec received payment from the U.S. Treasury in July 2023. Consistent with certain terms agreed upon in connection with the sale of Indian Point Energy Center in May 2021, Holtec transferred $40 million to Entergy for its pro-rata share of the litigation proceeds in August 2023. The remainder of the judgment was retained by Holtec. The effect of recording Entergy’s pro-rata share of the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Entergy’s pro-rata share of the damages awarded included $18 million related to costs previously recorded as spending on the asset retirement obligation, $15 million related to costs previously recorded as other operation and maintenance expenses, $6 million related to costs previously recorded as plant, and $1 million related to costs previously recorded as taxes other than income taxes. In August 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $177 million in favor of Northstar Vermont Yankee, LLC (previously Entergy Nuclear Vermont Yankee) and against the DOE in the final round Vermont Yankee damages case. Northstar, as the current owner, received payment from the U.S. Treasury in November 2024 and subsequently transferred $127 million of the litigation proceeds to Entergy per the terms of the agreement for the disposition of Vermont Yankee, which included $107 million for independent spent fuel storage installation expansion, and related to a long-term note receivable issued to Entergy at the time of the disposition of Vermont Yankee, and $20 million for costs related to independent spent fuel storage installation operations, both as required by the disposition documents. Northstar retained $10 million of the litigation proceeds, and the remaining $40 million of the total litigation proceeds was placed by Northstar into an escrow account and is expected to be transferred to Entergy upon the satisfaction of certain agreed upon conditions. The effect of recording Entergy’s share of the judgment was a reduction of $82 million in principle and $25 million in accrued interest on the long-term note receivable and a reduction to asset write-offs, impairments, and related charges (credits) of $20 million related to costs previously recorded as spending on the asset retirement obligation. In October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Payment to Holtec, as the current owner, from the U.S. Treasury is expected in first quarter 2025, at which time Holtec is expected to transfer the $7 million judgment to Entergy. The effect of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Management cannot predict the timing or amount of any potential recoveries on other claims filed by Entergy subsidiaries and cannot predict the timing of any eventual receipt from the DOE of the U.S. Court of Federal Claims damage awards. Nuclear Insurance Third Party Liability Insurance The Price-Anderson Act requires that reactor licensees purchase insurance and participate in a secondary insurance pool that provides insurance coverage for the public in the event of a nuclear power plant accident. The costs of this insurance are borne by the nuclear power industry. Congress amended and renewed the Price-Anderson Act in 2024 for a term through 2065. The Price-Anderson Act requires nuclear power plants to show evidence of financial protection in the event of a nuclear accident. This protection must consist of two layers of coverage: 1. The primary level is i nsurance underwritten by American Nuclear Insurers (ANI) and provides public liability insurance coverage of $500 million for each operating reactor. If this amount is not sufficient to cover claims arising from an accident, the second level, Secondary Financial Protection, applies. 2. Secondary Financial Protection: Curr ently, 95 nuclear reactors participate in the Secondary Financial Protection program, which provides approximately $15.8 billion in secondary layer insurance coverage to compensate the public in the event of a nuclear power reactor accident. The Price-Anderson Act provides that all potential liability for a nuclear accident is limited to the amounts of insurance coverage available under the primary and secondary layers. Within the Secondary Financial Protection program, each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident or fault, up to a maxi mum of approximately $165.9 million per reactor per incident (Entergy’s maximum total contingent obligation per incident is $829.6 million). This retrospective premium is assessable at approximately $24.7 million per year per incident per nuclear power reactor. 3. Total insurance coverage available is approximately $16.3 billion, among the primary ANI coverage and the Secondary Financial Protection program, to respond to a nuclear power plant accident that causes third-party damages (e.g., off-site property and environmental damage, off-site bodily injury, and on-site third-party bodily injury (i.e., contractors)). These coverages also respond to an accident caused by terrorism. Entergy Arkansas and Entergy Louisiana each have two licensed reactors. System Energy has one licensed reactor (10% of Grand Gulf is owned by a non-affiliated company (Cooperative Energy) that would share on a pro-rata basis in any retrospective premium assessment to System Energy under the Price-Anderson Act). Property Insurance Entergy’s nuclear owner/licensee subsidiaries are members of NEIL, a mutual insurance company that provides property damage coverage, including decontamination and reactor stabilization, to the members’ nuclear generating plants. The property damage insurance limits procured by Entergy for its nuclear plants are in compliance with the financial protection requirements of the NRC. These coverage limits, deductibles, and weekly indemnity periods are subject to change based on results of NEIL loss control inspections. The nuclear plants’ (ANO 1 and 2, Grand Gulf, River Bend, and Waterford 3) property damage insurance limits are $1.06 billion per occurrence at each plant. The property deductible is $20 million per site at the nuclear plants, except for earth movement, flood, and windstorm. Property damage from earth movement is excluded from the first $500 million in coverage for all nuclear plants. Property damage from flood is excluded from the first $500 million in coverage at ANO 1 and 2 and Grand Gulf. Property damage from flood for Waterford 3 and River Bend includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a maximum deductible of $50 million. Property damage from a windstorm for all of the nuclear plants includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a total maximum deductible of $50 million. In addition, Waterford 3 and Entergy’s portion of Grand Gulf are also covered under NEIL’s Accidental Outage Coverage program. Accidental outage coverage provides indemnification for the actual cost incurred in the event of an unplanned outage resulting from property damage covered under the NEIL Primary Property Insurance policy, subject to a deductible period. The indemnification is based on market power prices at the time of the loss, actual costs incurred during the outage, and the respective limits of each nuclear plant. After the deductible period has passed, weekly indemnities for an unplanned nuclear or non-nuclear outage, covered under NEIL’s Accidental Outage Coverage program, would be paid according to the amounts listed below: • 100% of the weekly indemnity for each week for the initial payment period of 52 weeks for nuclear and non-nuclear loss; then • 80% of the weekly indemnity for each week for the final payment period of 110 weeks for nuclear loss only; or • 60% of the weekly indemnity for each week for the final payment period of 52 weeks for non-nuclear loss only. Under the property damage and accidental outage insurance programs, all NEIL insured plants could be subject to assessments should losses exceed the accumulated funds available from NEIL. The assessments are subject to change based on results of NEIL underwriting. The current maximum amounts of such possible assessments per occurrence are as follows: Assessments (In Millions) Entergy Arkansas $20.0 Entergy Louisiana $37.6 Entergy Mississippi $0.1 Entergy New Orleans $0.1 Entergy Texas N/A System Energy $14.4 NRC regulations provide that the proceeds of this insurance must be used, first, to render the reactor safe and stable, and second, to complete decontamination operations. Only after proceeds are dedicated for such use and regulatory approval is secured would any remaining proceeds be made available for the benefit of plant owners or their creditors. In the event that one or more acts of terrorism causes property damage from a nuclear event under one or more or all nuclear insurance policies issued by NEIL (including, but not limited to, those described above) within 12 months from the date the first property damage occurs, the maximum recovery under all such nuclear insurance policies shall be an aggregate not exceedi ng $3.24 billion plus the additional amounts recovered for such losses from reinsurance, indemnity, and any other sources applicable to such losses. Non-Nuclear Property Insurance Entergy’s non-nuclear property insurance program provides coverage on a system-wide basis for Entergy’s non-nuclear assets. The insurance program provides coverage for property damage up to $400 million per occurrence in excess of a $20 million self-insured retention except for property damage caused by the following: earthquake shock, flood, and named windstorm, including associated storm surge. For earthquake shock and flood, the insurance program provides coverage up to $400 million on an annual aggregate basis in excess of a $40 million self-insured retention. For named windstorm and associated storm surge, the insurance program provides coverage up to $125 million on an annual aggregate basis in excess of a $40 million self-insured retention. The coverage provided by the insurance program for the Entergy New Orleans gas distribution system is limited to $50 million per occurrence and is subject to the same annual aggregate limits and retentions listed above for earthquake shock, flood, and named windstorm, including associated storm surge. Covered property generally includes power plants, substations, facilities, inventories, and gas distribution-related properties. Excluded property generally includes transmission and distribution lines, poles, and towers. For substations valued at $5 million or less, coverage for named windstorm and associated storm surge is excluded. This coverage is in place for Entergy Corporation, the Registrant Subsidiaries, and certain other Entergy subsidiaries. Entergy also purchases $400 million in terrorism insurance coverage for its conventional property. Employment and Labor-related Proceedings The Registrant Subsidiaries and other Entergy subsidiaries and related entities are responding to various lawsuits in both state and federal courts and to other labor-related proceedings filed by current and former employees, recognized bargaining representatives, and certain third parties. Generally, the amount of damages being sought is not specified in these proceedings. These actions may include, but are not limited to, allegations of wrongful employment actions; wage disputes and other claims under the Fair Labor Standards Act or its state counterparts; claims of race, gender, age, and disability discrimination; disputes arising under collective bargaining agreements; unfair labor practice proceedings and other administrative proceedings before the National Labor Relations Board or concerning the National Labor Relations Act; claims of retaliation; claims of harassment and hostile work environment; and claims for or regarding benefits under various Entergy Corporation-sponsored employee benefit plans. Entergy and the Registrant Subsidiaries and related entities are responding to these lawsuits and proceedings and deny liability to the claimants. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of Entergy or the Registrant Subsidiaries. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) Numerous lawsuits have been filed in state courts against primarily Entergy Louisiana and Entergy Texas by individuals alleging exposure to asbestos while working at Entergy facilities between 1955 and 1980. Entergy is being sued as a premises owner. Many other defendants are named in these lawsuits as well. Currently, there are approximately 185 lawsuits involving approximately 330 claimants. Management believes that adequate provisions have been established to cover any exposure. Additionally, negotiations continue with insurers to recover reimbursements. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of the Utility operating companies. Grand Gulf-Related Agreements Unit Power Sales Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy sells all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. Charges under this agreement are paid in consideration for the purchasing companies’ respective entitlement to receive capacity and energy and are payable irrespective of the quantity of energy delivered. Grand Gulf’s operating license currently extends through 2044. Monthly obligations are based on actual capacity and energy costs. The average monthly payments for 2024 under the agreement were approximately $16.8 million for Entergy Arkansas, $7.0 million for Entergy Louisiana, $16.4 million for Entergy Mississippi, and $8.4 million for Entergy New Orleans. See Note 2 to the financial statements for discussion of proceedings regarding the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture is being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a PPA governed by the MSS-4 replacement tariff. As discussed in Note 2 to the financial statements, in September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The MSS-4 replacement PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumes any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025. See Note 2 to the financial statements for discussion of the System Energy settlement with the LPSC. Availability Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans are individually obligated to make payments or subordinated advances to System Energy in accordance with stated percentages (Entergy Arkansas - 17.1%, Entergy Louisiana - 26.9%, Entergy Mississippi - 31.3%, and Entergy New Orleans - 24.7%) in amounts that, when added to amounts received under the Unit Power Sales Agreement or otherwise, are adequate to cover all of System Energy’s operating expenses as defined, including expenses incurred in connection with a permanent shutdown of Grand Gulf. System Energy has assigned its rights to payments and advances to certain creditors as security for certain of its debt obligations. Since commercial operation of Grand Gulf began, payments under the Unit Power Sales Agreement to System Energy have exceeded the amounts payable under the Availability Agreement and, therefore, no payments under the Availability Agreement have ever been required. However, if Entergy Arkansas or Entergy Mississippi fails to make its Unit Power Sales Agreement payments, and System Energy is unable to obtain funds from other sources, Entergy Louisiana and Entergy New Orleans could become subject to claims or demands by System Energy or certain of its creditors for payments or advances under the Availability Agreement (or the assignments thereof) equal to the difference between their required Unit Power Sales Agreement payments and their required Availability Agreement payments because their allocated shares under the Availability Agreement exceed their allocated shares under the Unit Power Sales Agreement. Under the Entergy Louisiana divestiture described in “ Unit Power Sales Agreement ” above, Entergy Mississippi assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, effective as of January 1, 2025. Reallocation Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans entered into the Reallocation Agreement relating to the sale of capacity and energy from Grand Gulf and the related costs, in which Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans agreed to assume all of Entergy Arkansas’s responsibilities and obligations with respect to Grand Gulf under the Availability Agreement. The FERC’s decision allocating a portion of Grand Gulf capacity and energy to Entergy Arkansas supersedes the Reallocation Agreement as it relates to Grand Gulf. Effective December 2024, the parties terminated the Reallocation Agreement.

As a result, in third quarter 2023, Entergy Arkansas recorded write-offs of its regulatory asset for deferred fuel of $68.9 million, which includes interest, and the undepreciated balance of $9.5 million in capital costs related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. Spent Nuclear Fuel Litigation Under the Nuclear Waste Policy Act of 1982, the DOE is required, for a specified fee, to construct storage facilities for, and to dispose of, all spent nuclear fuel and other high-level radioactive waste generated by domestic nuclear power reactors. Entergy’s nuclear owner/licensee subsidiaries have been charged fees for the estimated future disposal costs of spent nuclear fuel in accordance with the Nuclear Waste Policy Act of 1982. The affected Entergy companies entered into contracts with the DOE, whereby the DOE is to furnish disposal services at a cost of one mill per net kWh generated and sold after April 7, 1983, plus a one-time fee for generation prior to that date. Entergy considers all costs incurred for the disposal of spent nuclear fuel, except accrued interest, to be proper components of nuclear fuel expense. Provisions to recover such costs have been or will be made in applications to regulatory authorities for the Utility plants. Following the defunding of the Yucca Mountain spent fuel repository program, the National Association of Regulatory Utility Commissioners and others sued the government seeking cessation of collection of the one mill per net kWh generated and sold after April 7, 1983 fee. In November 2013 the D.C. Circuit ordered the DOE to submit a proposal to Congress to reset the fee to zero until the DOE complies with the Nuclear Waste Policy Act or Congress enacts an alternative waste disposal plan. In January 2014 the DOE submitted the proposal to Congress under protest, and also filed a petition for rehearing with the D.C. Circuit. The petition for rehearing was denied. The zero spent fuel fee went into effect prospectively in May 2014. Because the DOE has not begun accepting spent fuel, it is in non-compliance with the Nuclear Waste Policy Act of 1982 and is in partial breach of its spent fuel disposal contracts. As a result of the DOE’s failure to begin disposal of spent nuclear fuel in 1998 pursuant to the Nuclear Waste Policy Act of 1982 and the spent fuel disposal contracts, Entergy’s nuclear owner/licensee subsidiaries have incurred and will continue to incur damages. Beginning in November 2003 these subsidiaries have pursued litigation to recover the damages caused by the DOE’s delay in performance. Following are details of final judgments recorded by Entergy in 2022, 2023, and 2024 related to Entergy’s nuclear owner/licensee subsidiaries’ litigation with the DOE. In October 2021 the U.S. Court of Federal Claims issued a final judgment in the amount of $83 million in favor of Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC against the DOE in the Indian Point 2 third round and Indian Point 3 second round combined damages case. Entergy received payment from the U.S. Treasury in January 2022. The effect in 2021 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $32 million related to costs previously recorded as plant, $47 million related to costs previously recorded as other operation and maintenance expenses, and $4 million related to costs previously recorded as taxes other than income taxes. In March 2023 the DOE submitted an offer of judgment to resolve claims in the fourth round ANO damages case. The $41 million offer was accepted by Entergy Arkansas, and the U.S. Court of Federal Claims issued a judgment in that amount in favor of Entergy Arkansas and against the DOE. Entergy Arkansas received payment from the U.S. Treasury in April 2023. The effects of recording the judgment were reductions to plant, nuclear fuel expense, other operation and maintenance expenses, materials and supplies, and taxes other than income taxes. The ANO damages awarded included $18 million related to costs previously recorded as plant, $10 million related to costs previously recorded as other operation and maintenance expenses, $8 million related to costs previously recorded as nuclear fuel expense, $3 million related to costs previously recorded as materials and supplies, and $2 million related to costs previously recorded as taxes other than income taxes. In July 2023 the DOE submitted an offer of judgment to resolve claims in the Indian Point 2 fourth round and Indian Point 3 third round combined damages case. The $59 million offer was accepted by Entergy and Holtec International, as the current owner. The U.S. Court of Federal Claims issued a final judgment in that amount in favor of Holtec Indian Point 2, LLC and Holtec Indian Point 3, LLC (previously Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC) and against the DOE. Holtec received payment from the U.S. Treasury in July 2023. Consistent with certain terms agreed upon in connection with the sale of Indian Point Energy Center in May 2021, Holtec transferred $40 million to Entergy for its pro-rata share of the litigation proceeds in August 2023. The remainder of the judgment was retained by Holtec. The effect of recording Entergy’s pro-rata share of the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Entergy’s pro-rata share of the damages awarded included $18 million related to costs previously recorded as spending on the asset retirement obligation, $15 million related to costs previously recorded as other operation and maintenance expenses, $6 million related to costs previously recorded as plant, and $1 million related to costs previously recorded as taxes other than income taxes. In August 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $177 million in favor of Northstar Vermont Yankee, LLC (previously Entergy Nuclear Vermont Yankee) and against the DOE in the final round Vermont Yankee damages case. Northstar, as the current owner, received payment from the U.S. Treasury in November 2024 and subsequently transferred $127 million of the litigation proceeds to Entergy per the terms of the agreement for the disposition of Vermont Yankee, which included $107 million for independent spent fuel storage installation expansion, and related to a long-term note receivable issued to Entergy at the time of the disposition of Vermont Yankee, and $20 million for costs related to independent spent fuel storage installation operations, both as required by the disposition documents. Northstar retained $10 million of the litigation proceeds, and the remaining $40 million of the total litigation proceeds was placed by Northstar into an escrow account and is expected to be transferred to Entergy upon the satisfaction of certain agreed upon conditions. The effect of recording Entergy’s share of the judgment was a reduction of $82 million in principle and $25 million in accrued interest on the long-term note receivable and a reduction to asset write-offs, impairments, and related charges (credits) of $20 million related to costs previously recorded as spending on the asset retirement obligation. In October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Payment to Holtec, as the current owner, from the U.S. Treasury is expected in first quarter 2025, at which time Holtec is expected to transfer the $7 million judgment to Entergy. The effect of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Management cannot predict the timing or amount of any potential recoveries on other claims filed by Entergy subsidiaries and cannot predict the timing of any eventual receipt from the DOE of the U.S. Court of Federal Claims damage awards. Nuclear Insurance Third Party Liability Insurance The Price-Anderson Act requires that reactor licensees purchase insurance and participate in a secondary insurance pool that provides insurance coverage for the public in the event of a nuclear power plant accident. The costs of this insurance are borne by the nuclear power industry. Congress amended and renewed the Price-Anderson Act in 2024 for a term through 2065. The Price-Anderson Act requires nuclear power plants to show evidence of financial protection in the event of a nuclear accident. This protection must consist of two layers of coverage: 1. The primary level is i nsurance underwritten by American Nuclear Insurers (ANI) and provides public liability insurance coverage of $500 million for each operating reactor. If this amount is not sufficient to cover claims arising from an accident, the second level, Secondary Financial Protection, applies. 2. Secondary Financial Protection: Curr ently, 95 nuclear reactors participate in the Secondary Financial Protection program, which provides approximately $15.8 billion in secondary layer insurance coverage to compensate the public in the event of a nuclear power reactor accident. The Price-Anderson Act provides that all potential liability for a nuclear accident is limited to the amounts of insurance coverage available under the primary and secondary layers. Within the Secondary Financial Protection program, each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident or fault, up to a maxi mum of approximately $165.9 million per reactor per incident (Entergy’s maximum total contingent obligation per incident is $829.6 million). This retrospective premium is assessable at approximately $24.7 million per year per incident per nuclear power reactor. 3. Total insurance coverage available is approximately $16.3 billion, among the primary ANI coverage and the Secondary Financial Protection program, to respond to a nuclear power plant accident that causes third-party damages (e.g., off-site property and environmental damage, off-site bodily injury, and on-site third-party bodily injury (i.e., contractors)). These coverages also respond to an accident caused by terrorism. Entergy Arkansas and Entergy Louisiana each have two licensed reactors. System Energy has one licensed reactor (10% of Grand Gulf is owned by a non-affiliated company (Cooperative Energy) that would share on a pro-rata basis in any retrospective premium assessment to System Energy under the Price-Anderson Act). Property Insurance Entergy’s nuclear owner/licensee subsidiaries are members of NEIL, a mutual insurance company that provides property damage coverage, including decontamination and reactor stabilization, to the members’ nuclear generating plants. The property damage insurance limits procured by Entergy for its nuclear plants are in compliance with the financial protection requirements of the NRC. These coverage limits, deductibles, and weekly indemnity periods are subject to change based on results of NEIL loss control inspections. The nuclear plants’ (ANO 1 and 2, Grand Gulf, River Bend, and Waterford 3) property damage insurance limits are $1.06 billion per occurrence at each plant. The property deductible is $20 million per site at the nuclear plants, except for earth movement, flood, and windstorm. Property damage from earth movement is excluded from the first $500 million in coverage for all nuclear plants. Property damage from flood is excluded from the first $500 million in coverage at ANO 1 and 2 and Grand Gulf. Property damage from flood for Waterford 3 and River Bend includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a maximum deductible of $50 million. Property damage from a windstorm for all of the nuclear plants includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a total maximum deductible of $50 million. In addition, Waterford 3 and Entergy’s portion of Grand Gulf are also covered under NEIL’s Accidental Outage Coverage program. Accidental outage coverage provides indemnification for the actual cost incurred in the event of an unplanned outage resulting from property damage covered under the NEIL Primary Property Insurance policy, subject to a deductible period. The indemnification is based on market power prices at the time of the loss, actual costs incurred during the outage, and the respective limits of each nuclear plant. After the deductible period has passed, weekly indemnities for an unplanned nuclear or non-nuclear outage, covered under NEIL’s Accidental Outage Coverage program, would be paid according to the amounts listed below: • 100% of the weekly indemnity for each week for the initial payment period of 52 weeks for nuclear and non-nuclear loss; then • 80% of the weekly indemnity for each week for the final payment period of 110 weeks for nuclear loss only; or • 60% of the weekly indemnity for each week for the final payment period of 52 weeks for non-nuclear loss only. Under the property damage and accidental outage insurance programs, all NEIL insured plants could be subject to assessments should losses exceed the accumulated funds available from NEIL. The assessments are subject to change based on results of NEIL underwriting. The current maximum amounts of such possible assessments per occurrence are as follows: Assessments (In Millions) Entergy Arkansas $20.0 Entergy Louisiana $37.6 Entergy Mississippi $0.1 Entergy New Orleans $0.1 Entergy Texas N/A System Energy $14.4 NRC regulations provide that the proceeds of this insurance must be used, first, to render the reactor safe and stable, and second, to complete decontamination operations. Only after proceeds are dedicated for such use and regulatory approval is secured would any remaining proceeds be made available for the benefit of plant owners or their creditors. In the event that one or more acts of terrorism causes property damage from a nuclear event under one or more or all nuclear insurance policies issued by NEIL (including, but not limited to, those described above) within 12 months from the date the first property damage occurs, the maximum recovery under all such nuclear insurance policies shall be an aggregate not exceedi ng $3.24 billion plus the additional amounts recovered for such losses from reinsurance, indemnity, and any other sources applicable to such losses. Non-Nuclear Property Insurance Entergy’s non-nuclear property insurance program provides coverage on a system-wide basis for Entergy’s non-nuclear assets. The insurance program provides coverage for property damage up to $400 million per occurrence in excess of a $20 million self-insured retention except for property damage caused by the following: earthquake shock, flood, and named windstorm, including associated storm surge. For earthquake shock and flood, the insurance program provides coverage up to $400 million on an annual aggregate basis in excess of a $40 million self-insured retention. For named windstorm and associated storm surge, the insurance program provides coverage up to $125 million on an annual aggregate basis in excess of a $40 million self-insured retention. The coverage provided by the insurance program for the Entergy New Orleans gas distribution system is limited to $50 million per occurrence and is subject to the same annual aggregate limits and retentions listed above for earthquake shock, flood, and named windstorm, including associated storm surge. Covered property generally includes power plants, substations, facilities, inventories, and gas distribution-related properties. Excluded property generally includes transmission and distribution lines, poles, and towers. For substations valued at $5 million or less, coverage for named windstorm and associated storm surge is excluded. This coverage is in place for Entergy Corporation, the Registrant Subsidiaries, and certain other Entergy subsidiaries. Entergy also purchases $400 million in terrorism insurance coverage for its conventional property. Employment and Labor-related Proceedings The Registrant Subsidiaries and other Entergy subsidiaries and related entities are responding to various lawsuits in both state and federal courts and to other labor-related proceedings filed by current and former employees, recognized bargaining representatives, and certain third parties. Generally, the amount of damages being sought is not specified in these proceedings. These actions may include, but are not limited to, allegations of wrongful employment actions; wage disputes and other claims under the Fair Labor Standards Act or its state counterparts; claims of race, gender, age, and disability discrimination; disputes arising under collective bargaining agreements; unfair labor practice proceedings and other administrative proceedings before the National Labor Relations Board or concerning the National Labor Relations Act; claims of retaliation; claims of harassment and hostile work environment; and claims for or regarding benefits under various Entergy Corporation-sponsored employee benefit plans. Entergy and the Registrant Subsidiaries and related entities are responding to these lawsuits and proceedings and deny liability to the claimants. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of Entergy or the Registrant Subsidiaries. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) Numerous lawsuits have been filed in state courts against primarily Entergy Louisiana and Entergy Texas by individuals alleging exposure to asbestos while working at Entergy facilities between 1955 and 1980. Entergy is being sued as a premises owner. Many other defendants are named in these lawsuits as well. Currently, there are approximately 185 lawsuits involving approximately 330 claimants. Management believes that adequate provisions have been established to cover any exposure. Additionally, negotiations continue with insurers to recover reimbursements. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of the Utility operating companies. Grand Gulf-Related Agreements Unit Power Sales Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy sells all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. Charges under this agreement are paid in consideration for the purchasing companies’ respective entitlement to receive capacity and energy and are payable irrespective of the quantity of energy delivered. Grand Gulf’s operating license currently extends through 2044. Monthly obligations are based on actual capacity and energy costs. The average monthly payments for 2024 under the agreement were approximately $16.8 million for Entergy Arkansas, $7.0 million for Entergy Louisiana, $16.4 million for Entergy Mississippi, and $8.4 million for Entergy New Orleans. See Note 2 to the financial statements for discussion of proceedings regarding the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture is being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a PPA governed by the MSS-4 replacement tariff. As discussed in Note 2 to the financial statements, in September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The MSS-4 replacement PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumes any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025. See Note 2 to the financial statements for discussion of the System Energy settlement with the LPSC. Availability Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans are individually obligated to make payments or subordinated advances to System Energy in accordance with stated percentages (Entergy Arkansas - 17.1%, Entergy Louisiana - 26.9%, Entergy Mississippi - 31.3%, and Entergy New Orleans - 24.7%) in amounts that, when added to amounts received under the Unit Power Sales Agreement or otherwise, are adequate to cover all of System Energy’s operating expenses as defined, including expenses incurred in connection with a permanent shutdown of Grand Gulf. System Energy has assigned its rights to payments and advances to certain creditors as security for certain of its debt obligations. Since commercial operation of Grand Gulf began, payments under the Unit Power Sales Agreement to System Energy have exceeded the amounts payable under the Availability Agreement and, therefore, no payments under the Availability Agreement have ever been required. However, if Entergy Arkansas or Entergy Mississippi fails to make its Unit Power Sales Agreement payments, and System Energy is unable to obtain funds from other sources, Entergy Louisiana and Entergy New Orleans could become subject to claims or demands by System Energy or certain of its creditors for payments or advances under the Availability Agreement (or the assignments thereof) equal to the difference between their required Unit Power Sales Agreement payments and their required Availability Agreement payments because their allocated shares under the Availability Agreement exceed their allocated shares under the Unit Power Sales Agreement. Under the Entergy Louisiana divestiture described in “ Unit Power Sales Agreement ” above, Entergy Mississippi assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, effective as of January 1, 2025. Reallocation Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans entered into the Reallocation Agreement relating to the sale of capacity and energy from Grand Gulf and the related costs, in which Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans agreed to assume all of Entergy Arkansas’s responsibilities and obligations with respect to Grand Gulf under the Availability Agreement. The FERC’s decision allocating a portion of Grand Gulf capacity and energy to Entergy Arkansas supersedes the Reallocation Agreement as it relates to Grand Gulf. Effective December 2024, the parties terminated the Reallocation Agreement.
Entergy New Orleans [Member]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition. Entergy discusses regulatory proceedings in Note 2 to the financial statements and discusses tax proceedings in Note 3 to the financial statements. Vidalia Purchased Power Agreement Entergy Louisiana has an agreement extending through the year 2031 to purchase energy generated by a hydroelectric facility known as the Vidalia project. Entergy Louisiana made payments under the contract of approximately $116.8 million in 2024, $100.4 million in 2023, and $117.2 million in 2022. If the maximum percentage (94%) of the energy is made available to Entergy Louisiana, current production projections would require estimated payments of approximately $121.7 million in 2025 and a total of $730.3 million for the years 2026 through 2031. Entergy Louisiana currently recovers the costs of the purchased energy through its fuel adjustment clause. In an LPSC-approved settlement related to tax benefits from the tax treatment of the Vidalia contract, Entergy Louisiana agreed to credit rates by $11 million each year for up to 10 years, beginning in October 2002. In October 2011 the LPSC approved a settlement under which Entergy Louisiana agreed to provide credits to customers by crediting billings an additional $20.235 million per year for 15 years beginning January 2012. Entergy Louisiana recorded a regulatory charge and a corresponding regulatory liability to reflect this obligation. The settlement agreement allowed for an adjustment to the credits if, among other things, there was a change in the applicable federal or state income tax rate. As a result of the enactment of the Tax Cuts and Jobs Act, in December 2017, and the lowering of the federal corporate income tax rate from 35% to 21%, the Vidalia purchased power regulatory liability was reduced by $30.5 million, with a corresponding increase to Other regulatory credits on the income statement. See Note 3 to the financial statements for discussion of the effects of the Tax Cuts and Jobs Act and discussion of the resolution of the 2016-2018 IRS audit, which included the tax treatment of the Vidalia contract. ANO Damage, Outage, and NRC Reviews In March 2013, during a scheduled refueling outage at ANO 1, a contractor-owned and operated heavy-lifting apparatus collapsed while moving the generator stator out of the turbine building. The collapse resulted in the death of an ironworker and injuries to several other contract workers, caused ANO 2 to shut down, and damaged the ANO turbine building. The total cost of assessment, restoration of off-site power, site restoration, debris removal, and replacement of damaged property and equipment was approximately $95 million. Entergy Arkansas pursued its options for recovering damages that resulted from the stator drop, including its insurance coverage and legal action. Entergy Arkansas collected $50 million in 2014 from Nuclear Electric Insurance Limited (NEIL), a mutual insurance company that provides property damage coverage to the members’ nuclear generating plants. Entergy Arkansas also collected a total of $21 million in 2018 as a result of stator-related settlements. In addition, Entergy Arkansas incurred replacement power costs for ANO 2 power during its outage and incurred incremental replacement power costs for ANO 1 power because the outage extended beyond the originally-planned duration of the refueling outage. In February 2014 the APSC authorized Entergy Arkansas to retain $65.9 million in its deferred fuel balance with recovery to be reviewed in a later period after more information regarding various claims associated with the ANO stator incident was available. In March 2015, after several NRC inspections and regulatory conferences, arising from the stator incident, the NRC placed ANO into the “multiple/repetitive degraded cornerstone column,” or Column 4, of the NRC’s Reactor Oversight Process Action Matrix. Entergy Arkansas incurred incremental costs of approximately $53 million in 2015 to prepare for the NRC inspections that began in early 2016 in order to address the issues required to move ANO back to “licensee response” or Column 1 of the NRC’s Reactor Oversight Process Action Matrix. Excluding remediation and response costs that resulted from the additional NRC inspection activities, Entergy Arkansas incurred approximately $44 million in 2016 and $7 million in 2017 in support of NRC inspection activities and to implement Entergy Arkansas’s performance improvement initiatives developed in 2015. In June 2018 the NRC moved ANO 1 and 2 into the “licensee response column,” or Column 1, of the NRC’s Reactor Oversight Process Action Matrix. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the identified costs resulting from the ANO stator incident, specifically all incremental fuel and purchased energy expense, capital and incremental non-fuel operations and maintenance costs, and costs of any judgment that may be rendered against Entergy Arkansas in civil litigation that is not covered by insurance. As a result, in third quarter 2023, Entergy Arkansas recorded write-offs of its regulatory asset for deferred fuel of $68.9 million, which includes interest, and the undepreciated balance of $9.5 million in capital costs related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. Spent Nuclear Fuel Litigation Under the Nuclear Waste Policy Act of 1982, the DOE is required, for a specified fee, to construct storage facilities for, and to dispose of, all spent nuclear fuel and other high-level radioactive waste generated by domestic nuclear power reactors.

Following are details of final judgments recorded by Entergy in 2022, 2023, and 2024 related to Entergy’s nuclear owner/licensee subsidiaries’ litigation with the DOE. In October 2021 the U.S. Court of Federal Claims issued a final judgment in the amount of $83 million in favor of Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC against the DOE in the Indian Point 2 third round and Indian Point 3 second round combined damages case. Entergy received payment from the U.S. Treasury in January 2022. The effect in 2021 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $32 million related to costs previously recorded as plant, $47 million related to costs previously recorded as other operation and maintenance expenses, and $4 million related to costs previously recorded as taxes other than income taxes. In March 2023 the DOE submitted an offer of judgment to resolve claims in the fourth round ANO damages case. The $41 million offer was accepted by Entergy Arkansas, and the U.S. Court of Federal Claims issued a judgment in that amount in favor of Entergy Arkansas and against the DOE. Entergy Arkansas received payment from the U.S. Treasury in April 2023. The effects of recording the judgment were reductions to plant, nuclear fuel expense, other operation and maintenance expenses, materials and supplies, and taxes other than income taxes. The ANO damages awarded included $18 million related to costs previously recorded as plant, $10 million related to costs previously recorded as other operation and maintenance expenses, $8 million related to costs previously recorded as nuclear fuel expense, $3 million related to costs previously recorded as materials and supplies, and $2 million related to costs previously recorded as taxes other than income taxes. In July 2023 the DOE submitted an offer of judgment to resolve claims in the Indian Point 2 fourth round and Indian Point 3 third round combined damages case. The $59 million offer was accepted by Entergy and Holtec International, as the current owner. The U.S. Court of Federal Claims issued a final judgment in that amount in favor of Holtec Indian Point 2, LLC and Holtec Indian Point 3, LLC (previously Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC) and against the DOE. Holtec received payment from the U.S. Treasury in July 2023. Consistent with certain terms agreed upon in connection with the sale of Indian Point Energy Center in May 2021, Holtec transferred $40 million to Entergy for its pro-rata share of the litigation proceeds in August 2023. The remainder of the judgment was retained by Holtec. The effect of recording Entergy’s pro-rata share of the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Entergy’s pro-rata share of the damages awarded included $18 million related to costs previously recorded as spending on the asset retirement obligation, $15 million related to costs previously recorded as other operation and maintenance expenses, $6 million related to costs previously recorded as plant, and $1 million related to costs previously recorded as taxes other than income taxes. In August 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $177 million in favor of Northstar Vermont Yankee, LLC (previously Entergy Nuclear Vermont Yankee) and against the DOE in the final round Vermont Yankee damages case. Northstar, as the current owner, received payment from the U.S. Treasury in November 2024 and subsequently transferred $127 million of the litigation proceeds to Entergy per the terms of the agreement for the disposition of Vermont Yankee, which included $107 million for independent spent fuel storage installation expansion, and related to a long-term note receivable issued to Entergy at the time of the disposition of Vermont Yankee, and $20 million for costs related to independent spent fuel storage installation operations, both as required by the disposition documents. Northstar retained $10 million of the litigation proceeds, and the remaining $40 million of the total litigation proceeds was placed by Northstar into an escrow account and is expected to be transferred to Entergy upon the satisfaction of certain agreed upon conditions. The effect of recording Entergy’s share of the judgment was a reduction of $82 million in principle and $25 million in accrued interest on the long-term note receivable and a reduction to asset write-offs, impairments, and related charges (credits) of $20 million related to costs previously recorded as spending on the asset retirement obligation. In October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Payment to Holtec, as the current owner, from the U.S. Treasury is expected in first quarter 2025, at which time Holtec is expected to transfer the $7 million judgment to Entergy. The effect of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Management cannot predict the timing or amount of any potential recoveries on other claims filed by Entergy subsidiaries and cannot predict the timing of any eventual receipt from the DOE of the U.S. Court of Federal Claims damage awards. Nuclear Insurance Third Party Liability Insurance The Price-Anderson Act requires that reactor licensees purchase insurance and participate in a secondary insurance pool that provides insurance coverage for the public in the event of a nuclear power plant accident. The costs of this insurance are borne by the nuclear power industry. Congress amended and renewed the Price-Anderson Act in 2024 for a term through 2065. The Price-Anderson Act requires nuclear power plants to show evidence of financial protection in the event of a nuclear accident. This protection must consist of two layers of coverage: 1. The primary level is i nsurance underwritten by American Nuclear Insurers (ANI) and provides public liability insurance coverage of $500 million for each operating reactor. If this amount is not sufficient to cover claims arising from an accident, the second level, Secondary Financial Protection, applies. 2. Secondary Financial Protection: Curr ently, 95 nuclear reactors participate in the Secondary Financial Protection program, which provides approximately $15.8 billion in secondary layer insurance coverage to compensate the public in the event of a nuclear power reactor accident. The Price-Anderson Act provides that all potential liability for a nuclear accident is limited to the amounts of insurance coverage available under the primary and secondary layers. Within the Secondary Financial Protection program, each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident or fault, up to a maxi mum of approximately $165.9 million per reactor per incident (Entergy’s maximum total contingent obligation per incident is $829.6 million). This retrospective premium is assessable at approximately $24.7 million per year per incident per nuclear power reactor. 3. Total insurance coverage available is approximately $16.3 billion, among the primary ANI coverage and the Secondary Financial Protection program, to respond to a nuclear power plant accident that causes third-party damages (e.g., off-site property and environmental damage, off-site bodily injury, and on-site third-party bodily injury (i.e., contractors)). These coverages also respond to an accident caused by terrorism. Entergy Arkansas and Entergy Louisiana each have two licensed reactors. System Energy has one licensed reactor (10% of Grand Gulf is owned by a non-affiliated company (Cooperative Energy) that would share on a pro-rata basis in any retrospective premium assessment to System Energy under the Price-Anderson Act). Property Insurance Entergy’s nuclear owner/licensee subsidiaries are members of NEIL, a mutual insurance company that provides property damage coverage, including decontamination and reactor stabilization, to the members’ nuclear generating plants. The property damage insurance limits procured by Entergy for its nuclear plants are in compliance with the financial protection requirements of the NRC. These coverage limits, deductibles, and weekly indemnity periods are subject to change based on results of NEIL loss control inspections. The nuclear plants’ (ANO 1 and 2, Grand Gulf, River Bend, and Waterford 3) property damage insurance limits are $1.06 billion per occurrence at each plant. The property deductible is $20 million per site at the nuclear plants, except for earth movement, flood, and windstorm. Property damage from earth movement is excluded from the first $500 million in coverage for all nuclear plants. Property damage from flood is excluded from the first $500 million in coverage at ANO 1 and 2 and Grand Gulf. Property damage from flood for Waterford 3 and River Bend includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a maximum deductible of $50 million. Property damage from a windstorm for all of the nuclear plants includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a total maximum deductible of $50 million. In addition, Waterford 3 and Entergy’s portion of Grand Gulf are also covered under NEIL’s Accidental Outage Coverage program. Accidental outage coverage provides indemnification for the actual cost incurred in the event of an unplanned outage resulting from property damage covered under the NEIL Primary Property Insurance policy, subject to a deductible period. The indemnification is based on market power prices at the time of the loss, actual costs incurred during the outage, and the respective limits of each nuclear plant. After the deductible period has passed, weekly indemnities for an unplanned nuclear or non-nuclear outage, covered under NEIL’s Accidental Outage Coverage program, would be paid according to the amounts listed below: • 100% of the weekly indemnity for each week for the initial payment period of 52 weeks for nuclear and non-nuclear loss; then • 80% of the weekly indemnity for each week for the final payment period of 110 weeks for nuclear loss only; or • 60% of the weekly indemnity for each week for the final payment period of 52 weeks for non-nuclear loss only. Under the property damage and accidental outage insurance programs, all NEIL insured plants could be subject to assessments should losses exceed the accumulated funds available from NEIL. The assessments are subject to change based on results of NEIL underwriting. The current maximum amounts of such possible assessments per occurrence are as follows: Assessments (In Millions) Entergy Arkansas $20.0 Entergy Louisiana $37.6 Entergy Mississippi $0.1 Entergy New Orleans $0.1 Entergy Texas N/A System Energy $14.4 NRC regulations provide that the proceeds of this insurance must be used, first, to render the reactor safe and stable, and second, to complete decontamination operations. Only after proceeds are dedicated for such use and regulatory approval is secured would any remaining proceeds be made available for the benefit of plant owners or their creditors. In the event that one or more acts of terrorism causes property damage from a nuclear event under one or more or all nuclear insurance policies issued by NEIL (including, but not limited to, those described above) within 12 months from the date the first property damage occurs, the maximum recovery under all such nuclear insurance policies shall be an aggregate not exceedi ng $3.24 billion plus the additional amounts recovered for such losses from reinsurance, indemnity, and any other sources applicable to such losses. Non-Nuclear Property Insurance Entergy’s non-nuclear property insurance program provides coverage on a system-wide basis for Entergy’s non-nuclear assets. The insurance program provides coverage for property damage up to $400 million per occurrence in excess of a $20 million self-insured retention except for property damage caused by the following: earthquake shock, flood, and named windstorm, including associated storm surge. For earthquake shock and flood, the insurance program provides coverage up to $400 million on an annual aggregate basis in excess of a $40 million self-insured retention. For named windstorm and associated storm surge, the insurance program provides coverage up to $125 million on an annual aggregate basis in excess of a $40 million self-insured retention. The coverage provided by the insurance program for the Entergy New Orleans gas distribution system is limited to $50 million per occurrence and is subject to the same annual aggregate limits and retentions listed above for earthquake shock, flood, and named windstorm, including associated storm surge. Covered property generally includes power plants, substations, facilities, inventories, and gas distribution-related properties. Excluded property generally includes transmission and distribution lines, poles, and towers. For substations valued at $5 million or less, coverage for named windstorm and associated storm surge is excluded. This coverage is in place for Entergy Corporation, the Registrant Subsidiaries, and certain other Entergy subsidiaries. Entergy also purchases $400 million in terrorism insurance coverage for its conventional property. Employment and Labor-related Proceedings The Registrant Subsidiaries and other Entergy subsidiaries and related entities are responding to various lawsuits in both state and federal courts and to other labor-related proceedings filed by current and former employees, recognized bargaining representatives, and certain third parties. Generally, the amount of damages being sought is not specified in these proceedings. These actions may include, but are not limited to, allegations of wrongful employment actions; wage disputes and other claims under the Fair Labor Standards Act or its state counterparts; claims of race, gender, age, and disability discrimination; disputes arising under collective bargaining agreements; unfair labor practice proceedings and other administrative proceedings before the National Labor Relations Board or concerning the National Labor Relations Act; claims of retaliation; claims of harassment and hostile work environment; and claims for or regarding benefits under various Entergy Corporation-sponsored employee benefit plans. Entergy and the Registrant Subsidiaries and related entities are responding to these lawsuits and proceedings and deny liability to the claimants. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of Entergy or the Registrant Subsidiaries. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) Numerous lawsuits have been filed in state courts against primarily Entergy Louisiana and Entergy Texas by individuals alleging exposure to asbestos while working at Entergy facilities between 1955 and 1980. Entergy is being sued as a premises owner. Many other defendants are named in these lawsuits as well. Currently, there are approximately 185 lawsuits involving approximately 330 claimants. Management believes that adequate provisions have been established to cover any exposure. Additionally, negotiations continue with insurers to recover reimbursements. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of the Utility operating companies. Grand Gulf-Related Agreements Unit Power Sales Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy sells all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. Charges under this agreement are paid in consideration for the purchasing companies’ respective entitlement to receive capacity and energy and are payable irrespective of the quantity of energy delivered. Grand Gulf’s operating license currently extends through 2044. Monthly obligations are based on actual capacity and energy costs. The average monthly payments for 2024 under the agreement were approximately $16.8 million for Entergy Arkansas, $7.0 million for Entergy Louisiana, $16.4 million for Entergy Mississippi, and $8.4 million for Entergy New Orleans. See Note 2 to the financial statements for discussion of proceedings regarding the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture is being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a PPA governed by the MSS-4 replacement tariff. As discussed in Note 2 to the financial statements, in September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The MSS-4 replacement PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumes any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025. See Note 2 to the financial statements for discussion of the System Energy settlement with the LPSC. Availability Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans are individually obligated to make payments or subordinated advances to System Energy in accordance with stated percentages (Entergy Arkansas - 17.1%, Entergy Louisiana - 26.9%, Entergy Mississippi - 31.3%, and Entergy New Orleans - 24.7%) in amounts that, when added to amounts received under the Unit Power Sales Agreement or otherwise, are adequate to cover all of System Energy’s operating expenses as defined, including expenses incurred in connection with a permanent shutdown of Grand Gulf. System Energy has assigned its rights to payments and advances to certain creditors as security for certain of its debt obligations. Since commercial operation of Grand Gulf began, payments under the Unit Power Sales Agreement to System Energy have exceeded the amounts payable under the Availability Agreement and, therefore, no payments under the Availability Agreement have ever been required. However, if Entergy Arkansas or Entergy Mississippi fails to make its Unit Power Sales Agreement payments, and System Energy is unable to obtain funds from other sources, Entergy Louisiana and Entergy New Orleans could become subject to claims or demands by System Energy or certain of its creditors for payments or advances under the Availability Agreement (or the assignments thereof) equal to the difference between their required Unit Power Sales Agreement payments and their required Availability Agreement payments because their allocated shares under the Availability Agreement exceed their allocated shares under the Unit Power Sales Agreement. Under the Entergy Louisiana divestiture described in “ Unit Power Sales Agreement ” above, Entergy Mississippi assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, effective as of January 1, 2025. Reallocation Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans entered into the Reallocation Agreement relating to the sale of capacity and energy from Grand Gulf and the related costs, in which Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans agreed to assume all of Entergy Arkansas’s responsibilities and obligations with respect to Grand Gulf under the Availability Agreement. The FERC’s decision allocating a portion of Grand Gulf capacity and energy to Entergy Arkansas supersedes the Reallocation Agreement as it relates to Grand Gulf. Effective December 2024, the parties terminated the Reallocation Agreement.
Entergy Texas [Member]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition. Entergy discusses regulatory proceedings in Note 2 to the financial statements and discusses tax proceedings in Note 3 to the financial statements. Vidalia Purchased Power Agreement Entergy Louisiana has an agreement extending through the year 2031 to purchase energy generated by a hydroelectric facility known as the Vidalia project. Entergy Louisiana made payments under the contract of approximately $116.8 million in 2024, $100.4 million in 2023, and $117.2 million in 2022. If the maximum percentage (94%) of the energy is made available to Entergy Louisiana, current production projections would require estimated payments of approximately $121.7 million in 2025 and a total of $730.3 million for the years 2026 through 2031. Entergy Louisiana currently recovers the costs of the purchased energy through its fuel adjustment clause. In an LPSC-approved settlement related to tax benefits from the tax treatment of the Vidalia contract, Entergy Louisiana agreed to credit rates by $11 million each year for up to 10 years, beginning in October 2002. In October 2011 the LPSC approved a settlement under which Entergy Louisiana agreed to provide credits to customers by crediting billings an additional $20.235 million per year for 15 years beginning January 2012. Entergy Louisiana recorded a regulatory charge and a corresponding regulatory liability to reflect this obligation. The settlement agreement allowed for an adjustment to the credits if, among other things, there was a change in the applicable federal or state income tax rate. As a result of the enactment of the Tax Cuts and Jobs Act, in December 2017, and the lowering of the federal corporate income tax rate from 35% to 21%, the Vidalia purchased power regulatory liability was reduced by $30.5 million, with a corresponding increase to Other regulatory credits on the income statement. See Note 3 to the financial statements for discussion of the effects of the Tax Cuts and Jobs Act and discussion of the resolution of the 2016-2018 IRS audit, which included the tax treatment of the Vidalia contract. ANO Damage, Outage, and NRC Reviews In March 2013, during a scheduled refueling outage at ANO 1, a contractor-owned and operated heavy-lifting apparatus collapsed while moving the generator stator out of the turbine building. The collapse resulted in the death of an ironworker and injuries to several other contract workers, caused ANO 2 to shut down, and damaged the ANO turbine building. The total cost of assessment, restoration of off-site power, site restoration, debris removal, and replacement of damaged property and equipment was approximately $95 million. Entergy Arkansas pursued its options for recovering damages that resulted from the stator drop, including its insurance coverage and legal action. Entergy Arkansas collected $50 million in 2014 from Nuclear Electric Insurance Limited (NEIL), a mutual insurance company that provides property damage coverage to the members’ nuclear generating plants. Entergy Arkansas also collected a total of $21 million in 2018 as a result of stator-related settlements. In addition, Entergy Arkansas incurred replacement power costs for ANO 2 power during its outage and incurred incremental replacement power costs for ANO 1 power because the outage extended beyond the originally-planned duration of the refueling outage. In February 2014 the APSC authorized Entergy Arkansas to retain $65.9 million in its deferred fuel balance with recovery to be reviewed in a later period after more information regarding various claims associated with the ANO stator incident was available. In March 2015, after several NRC inspections and regulatory conferences, arising from the stator incident, the NRC placed ANO into the “multiple/repetitive degraded cornerstone column,” or Column 4, of the NRC’s Reactor Oversight Process Action Matrix. Entergy Arkansas incurred incremental costs of approximately $53 million in 2015 to prepare for the NRC inspections that began in early 2016 in order to address the issues required to move ANO back to “licensee response” or Column 1 of the NRC’s Reactor Oversight Process Action Matrix. Excluding remediation and response costs that resulted from the additional NRC inspection activities, Entergy Arkansas incurred approximately $44 million in 2016 and $7 million in 2017 in support of NRC inspection activities and to implement Entergy Arkansas’s performance improvement initiatives developed in 2015. In June 2018 the NRC moved ANO 1 and 2 into the “licensee response column,” or Column 1, of the NRC’s Reactor Oversight Process Action Matrix. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the identified costs resulting from the ANO stator incident, specifically all incremental fuel and purchased energy expense, capital and incremental non-fuel operations and maintenance costs, and costs of any judgment that may be rendered against Entergy Arkansas in civil litigation that is not covered by insurance. As a result, in third quarter 2023, Entergy Arkansas recorded write-offs of its regulatory asset for deferred fuel of $68.9 million, which includes interest, and the undepreciated balance of $9.5 million in capital costs related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. Spent Nuclear Fuel Litigation Under the Nuclear Waste Policy Act of 1982, the DOE is required, for a specified fee, to construct storage facilities for, and to dispose of, all spent nuclear fuel and other high-level radioactive waste generated by domestic nuclear power reactors. Entergy’s nuclear owner/licensee subsidiaries have been charged fees for the estimated future disposal costs of spent nuclear fuel in accordance with the Nuclear Waste Policy Act of 1982. The affected Entergy companies entered into contracts with the DOE, whereby the DOE is to furnish disposal services at a cost of one mill per net kWh generated and sold after April 7, 1983, plus a one-time fee for generation prior to that date. Entergy considers all costs incurred for the disposal of spent nuclear fuel, except accrued interest, to be proper components of nuclear fuel expense. Provisions to recover such costs have been or will be made in applications to regulatory authorities for the Utility plants. Following the defunding of the Yucca Mountain spent fuel repository program, the National Association of Regulatory Utility Commissioners and others sued the government seeking cessation of collection of the one mill per net kWh generated and sold after April 7, 1983 fee. In November 2013 the D.C. Circuit ordered the DOE to submit a proposal to Congress to reset the fee to zero until the DOE complies with the Nuclear Waste Policy Act or Congress enacts an alternative waste disposal plan. In January 2014 the DOE submitted the proposal to Congress under protest, and also filed a petition for rehearing with the D.C. Circuit. The petition for rehearing was denied. The zero spent fuel fee went into effect prospectively in May 2014. Because the DOE has not begun accepting spent fuel, it is in non-compliance with the Nuclear Waste Policy Act of 1982 and is in partial breach of its spent fuel disposal contracts. As a result of the DOE’s failure to begin disposal of spent nuclear fuel in 1998 pursuant to the Nuclear Waste Policy Act of 1982 and the spent fuel disposal contracts, Entergy’s nuclear owner/licensee subsidiaries have incurred and will continue to incur damages. Beginning in November 2003 these subsidiaries have pursued litigation to recover the damages caused by the DOE’s delay in performance. Following are details of final judgments recorded by Entergy in 2022, 2023, and 2024 related to Entergy’s nuclear owner/licensee subsidiaries’ litigation with the DOE. In October 2021 the U.S. Court of Federal Claims issued a final judgment in the amount of $83 million in favor of Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC against the DOE in the Indian Point 2 third round and Indian Point 3 second round combined damages case. Entergy received payment from the U.S. Treasury in January 2022. The effect in 2021 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $32 million related to costs previously recorded as plant, $47 million related to costs previously recorded as other operation and maintenance expenses, and $4 million related to costs previously recorded as taxes other than income taxes. In March 2023 the DOE submitted an offer of judgment to resolve claims in the fourth round ANO damages case. The $41 million offer was accepted by Entergy Arkansas, and the U.S. Court of Federal Claims issued a judgment in that amount in favor of Entergy Arkansas and against the DOE. Entergy Arkansas received payment from the U.S. Treasury in April 2023. The effects of recording the judgment were reductions to plant, nuclear fuel expense, other operation and maintenance expenses, materials and supplies, and taxes other than income taxes. The ANO damages awarded included $18 million related to costs previously recorded as plant, $10 million related to costs previously recorded as other operation and maintenance expenses, $8 million related to costs previously recorded as nuclear fuel expense, $3 million related to costs previously recorded as materials and supplies, and $2 million related to costs previously recorded as taxes other than income taxes. In July 2023 the DOE submitted an offer of judgment to resolve claims in the Indian Point 2 fourth round and Indian Point 3 third round combined damages case. The $59 million offer was accepted by Entergy and Holtec International, as the current owner. The U.S. Court of Federal Claims issued a final judgment in that amount in favor of Holtec Indian Point 2, LLC and Holtec Indian Point 3, LLC (previously Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC) and against the DOE. Holtec received payment from the U.S. Treasury in July 2023. Consistent with certain terms agreed upon in connection with the sale of Indian Point Energy Center in May 2021, Holtec transferred $40 million to Entergy for its pro-rata share of the litigation proceeds in August 2023. The remainder of the judgment was retained by Holtec. The effect of recording Entergy’s pro-rata share of the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Entergy’s pro-rata share of the damages awarded included $18 million related to costs previously recorded as spending on the asset retirement obligation, $15 million related to costs previously recorded as other operation and maintenance expenses, $6 million related to costs previously recorded as plant, and $1 million related to costs previously recorded as taxes other than income taxes. In August 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $177 million in favor of Northstar Vermont Yankee, LLC (previously Entergy Nuclear Vermont Yankee) and against the DOE in the final round Vermont Yankee damages case. Northstar, as the current owner, received payment from the U.S. Treasury in November 2024 and subsequently transferred $127 million of the litigation proceeds to Entergy per the terms of the agreement for the disposition of Vermont Yankee, which included $107 million for independent spent fuel storage installation expansion, and related to a long-term note receivable issued to Entergy at the time of the disposition of Vermont Yankee, and $20 million for costs related to independent spent fuel storage installation operations, both as required by the disposition documents. Northstar retained $10 million of the litigation proceeds, and the remaining $40 million of the total litigation proceeds was placed by Northstar into an escrow account and is expected to be transferred to Entergy upon the satisfaction of certain agreed upon conditions. The effect of recording Entergy’s share of the judgment was a reduction of $82 million in principle and $25 million in accrued interest on the long-term note receivable and a reduction to asset write-offs, impairments, and related charges (credits) of $20 million related to costs previously recorded as spending on the asset retirement obligation. In October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Payment to Holtec, as the current owner, from the U.S. Treasury is expected in first quarter 2025, at which time Holtec is expected to transfer the $7 million judgment to Entergy. The effect of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Management cannot predict the timing or amount of any potential recoveries on other claims filed by Entergy subsidiaries and cannot predict the timing of any eventual receipt from the DOE of the U.S. Court of Federal Claims damage awards. Nuclear Insurance Third Party Liability Insurance The Price-Anderson Act requires that reactor licensees purchase insurance and participate in a secondary insurance pool that provides insurance coverage for the public in the event of a nuclear power plant accident. The costs of this insurance are borne by the nuclear power industry. Congress amended and renewed the Price-Anderson Act in 2024 for a term through 2065. The Price-Anderson Act requires nuclear power plants to show evidence of financial protection in the event of a nuclear accident. This protection must consist of two layers of coverage: 1. The primary level is i nsurance underwritten by American Nuclear Insurers (ANI) and provides public liability insurance coverage of $500 million for each operating reactor. If this amount is not sufficient to cover claims arising from an accident, the second level, Secondary Financial Protection, applies. 2. Secondary Financial Protection: Curr ently, 95 nuclear reactors participate in the Secondary Financial Protection program, which provides approximately $15.8 billion in secondary layer insurance coverage to compensate the public in the event of a nuclear power reactor accident. The Price-Anderson Act provides that all potential liability for a nuclear accident is limited to the amounts of insurance coverage available under the primary and secondary layers. Within the Secondary Financial Protection program, each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident or fault, up to a maxi mum of approximately $165.9 million per reactor per incident (Entergy’s maximum total contingent obligation per incident is $829.6 million). This retrospective premium is assessable at approximately $24.7 million per year per incident per nuclear power reactor. 3. Total insurance coverage available is approximately $16.3 billion, among the primary ANI coverage and the Secondary Financial Protection program, to respond to a nuclear power plant accident that causes third-party damages (e.g., off-site property and environmental damage, off-site bodily injury, and on-site third-party bodily injury (i.e., contractors)). These coverages also respond to an accident caused by terrorism. Entergy Arkansas and Entergy Louisiana each have two licensed reactors. System Energy has one licensed reactor (10% of Grand Gulf is owned by a non-affiliated company (Cooperative Energy) that would share on a pro-rata basis in any retrospective premium assessment to System Energy under the Price-Anderson Act). Property Insurance Entergy’s nuclear owner/licensee subsidiaries are members of NEIL, a mutual insurance company that provides property damage coverage, including decontamination and reactor stabilization, to the members’ nuclear generating plants. The property damage insurance limits procured by Entergy for its nuclear plants are in compliance with the financial protection requirements of the NRC. These coverage limits, deductibles, and weekly indemnity periods are subject to change based on results of NEIL loss control inspections. The nuclear plants’ (ANO 1 and 2, Grand Gulf, River Bend, and Waterford 3) property damage insurance limits are $1.06 billion per occurrence at each plant. The property deductible is $20 million per site at the nuclear plants, except for earth movement, flood, and windstorm. Property damage from earth movement is excluded from the first $500 million in coverage for all nuclear plants. Property damage from flood is excluded from the first $500 million in coverage at ANO 1 and 2 and Grand Gulf. Property damage from flood for Waterford 3 and River Bend includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a maximum deductible of $50 million. Property damage from a windstorm for all of the nuclear plants includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a total maximum deductible of $50 million. In addition, Waterford 3 and Entergy’s portion of Grand Gulf are also covered under NEIL’s Accidental Outage Coverage program. Accidental outage coverage provides indemnification for the actual cost incurred in the event of an unplanned outage resulting from property damage covered under the NEIL Primary Property Insurance policy, subject to a deductible period. The indemnification is based on market power prices at the time of the loss, actual costs incurred during the outage, and the respective limits of each nuclear plant. After the deductible period has passed, weekly indemnities for an unplanned nuclear or non-nuclear outage, covered under NEIL’s Accidental Outage Coverage program, would be paid according to the amounts listed below: • 100% of the weekly indemnity for each week for the initial payment period of 52 weeks for nuclear and non-nuclear loss; then • 80% of the weekly indemnity for each week for the final payment period of 110 weeks for nuclear loss only; or • 60% of the weekly indemnity for each week for the final payment period of 52 weeks for non-nuclear loss only. Under the property damage and accidental outage insurance programs, all NEIL insured plants could be subject to assessments should losses exceed the accumulated funds available from NEIL. The assessments are subject to change based on results of NEIL underwriting. The current maximum amounts of such possible assessments per occurrence are as follows: Assessments (In Millions) Entergy Arkansas $20.0 Entergy Louisiana $37.6 Entergy Mississippi $0.1 Entergy New Orleans $0.1 Entergy Texas N/A System Energy $14.4 NRC regulations provide that the proceeds of this insurance must be used, first, to render the reactor safe and stable, and second, to complete decontamination operations. Only after proceeds are dedicated for such use and regulatory approval is secured would any remaining proceeds be made available for the benefit of plant owners or their creditors. In the event that one or more acts of terrorism causes property damage from a nuclear event under one or more or all nuclear insurance policies issued by NEIL (including, but not limited to, those described above) within 12 months from the date the first property damage occurs, the maximum recovery under all such nuclear insurance policies shall be an aggregate not exceedi ng $3.24 billion plus the additional amounts recovered for such losses from reinsurance, indemnity, and any other sources applicable to such losses. Non-Nuclear Property Insurance Entergy’s non-nuclear property insurance program provides coverage on a system-wide basis for Entergy’s non-nuclear assets. The insurance program provides coverage for property damage up to $400 million per occurrence in excess of a $20 million self-insured retention except for property damage caused by the following: earthquake shock, flood, and named windstorm, including associated storm surge. For earthquake shock and flood, the insurance program provides coverage up to $400 million on an annual aggregate basis in excess of a $40 million self-insured retention. For named windstorm and associated storm surge, the insurance program provides coverage up to $125 million on an annual aggregate basis in excess of a $40 million self-insured retention. The coverage provided by the insurance program for the Entergy New Orleans gas distribution system is limited to $50 million per occurrence and is subject to the same annual aggregate limits and retentions listed above for earthquake shock, flood, and named windstorm, including associated storm surge. Covered property generally includes power plants, substations, facilities, inventories, and gas distribution-related properties. Excluded property generally includes transmission and distribution lines, poles, and towers. For substations valued at $5 million or less, coverage for named windstorm and associated storm surge is excluded. This coverage is in place for Entergy Corporation, the Registrant Subsidiaries, and certain other Entergy subsidiaries. Entergy also purchases $400 million in terrorism insurance coverage for its conventional property. Employment and Labor-related Proceedings The Registrant Subsidiaries and other Entergy subsidiaries and related entities are responding to various lawsuits in both state and federal courts and to other labor-related proceedings filed by current and former employees, recognized bargaining representatives, and certain third parties. Generally, the amount of damages being sought is not specified in these proceedings. These actions may include, but are not limited to, allegations of wrongful employment actions; wage disputes and other claims under the Fair Labor Standards Act or its state counterparts; claims of race, gender, age, and disability discrimination; disputes arising under collective bargaining agreements; unfair labor practice proceedings and other administrative proceedings before the National Labor Relations Board or concerning the National Labor Relations Act; claims of retaliation; claims of harassment and hostile work environment; and claims for or regarding benefits under various Entergy Corporation-sponsored employee benefit plans. Entergy and the Registrant Subsidiaries and related entities are responding to these lawsuits and proceedings and deny liability to the claimants. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of Entergy or the Registrant Subsidiaries. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) Numerous lawsuits have been filed in state courts against primarily Entergy Louisiana and Entergy Texas by individuals alleging exposure to asbestos while working at Entergy facilities between 1955 and 1980. Entergy is being sued as a premises owner. Many other defendants are named in these lawsuits as well. Currently, there are approximately 185 lawsuits involving approximately 330 claimants. Management believes that adequate provisions have been established to cover any exposure. Additionally, negotiations continue with insurers to recover reimbursements. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of the Utility operating companies. Grand Gulf-Related Agreements Unit Power Sales Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy sells all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. Charges under this agreement are paid in consideration for the purchasing companies’ respective entitlement to receive capacity and energy and are payable irrespective of the quantity of energy delivered. Grand Gulf’s operating license currently extends through 2044. Monthly obligations are based on actual capacity and energy costs. The average monthly payments for 2024 under the agreement were approximately $16.8 million for Entergy Arkansas, $7.0 million for Entergy Louisiana, $16.4 million for Entergy Mississippi, and $8.4 million for Entergy New Orleans. See Note 2 to the financial statements for discussion of proceedings regarding the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture is being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a PPA governed by the MSS-4 replacement tariff. As discussed in Note 2 to the financial statements, in September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The MSS-4 replacement PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumes any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025. See Note 2 to the financial statements for discussion of the System Energy settlement with the LPSC. Availability Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans are individually obligated to make payments or subordinated advances to System Energy in accordance with stated percentages (Entergy Arkansas - 17.1%, Entergy Louisiana - 26.9%, Entergy Mississippi - 31.3%, and Entergy New Orleans - 24.7%) in amounts that, when added to amounts received under the Unit Power Sales Agreement or otherwise, are adequate to cover all of System Energy’s operating expenses as defined, including expenses incurred in connection with a permanent shutdown of Grand Gulf. System Energy has assigned its rights to payments and advances to certain creditors as security for certain of its debt obligations. Since commercial operation of Grand Gulf began, payments under the Unit Power Sales Agreement to System Energy have exceeded the amounts payable under the Availability Agreement and, therefore, no payments under the Availability Agreement have ever been required. However, if Entergy Arkansas or Entergy Mississippi fails to make its Unit Power Sales Agreement payments, and System Energy is unable to obtain funds from other sources, Entergy Louisiana and Entergy New Orleans could become subject to claims or demands by System Energy or certain of its creditors for payments or advances under the Availability Agreement (or the assignments thereof) equal to the difference between their required Unit Power Sales Agreement payments and their required Availability Agreement payments because their allocated shares under the Availability Agreement exceed their allocated shares under the Unit Power Sales Agreement. Under the Entergy Louisiana divestiture described in “ Unit Power Sales Agreement ” above, Entergy Mississippi assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, effective as of January 1, 2025. Reallocation Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans entered into the Reallocation Agreement relating to the sale of capacity and energy from Grand Gulf and the related costs, in which Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans agreed to assume all of Entergy Arkansas’s responsibilities and obligations with respect to Grand Gulf under the Availability Agreement. The FERC’s decision allocating a portion of Grand Gulf capacity and energy to Entergy Arkansas supersedes the Reallocation Agreement as it relates to Grand Gulf. Effective December 2024, the parties terminated the Reallocation Agreement.

Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition. Entergy discusses regulatory proceedings in Note 2 to the financial statements and discusses tax proceedings in Note 3 to the financial statements. Vidalia Purchased Power Agreement Entergy Louisiana has an agreement extending through the year 2031 to purchase energy generated by a hydroelectric facility known as the Vidalia project. Entergy Louisiana made payments under the contract of approximately $116.8 million in 2024, $100.4 million in 2023, and $117.2 million in 2022. If the maximum percentage (94%) of the energy is made available to Entergy Louisiana, current production projections would require estimated payments of approximately $121.7 million in 2025 and a total of $730.3 million for the years 2026 through 2031. Entergy Louisiana currently recovers the costs of the purchased energy through its fuel adjustment clause. In an LPSC-approved settlement related to tax benefits from the tax treatment of the Vidalia contract, Entergy Louisiana agreed to credit rates by $11 million each year for up to 10 years, beginning in October 2002. In October 2011 the LPSC approved a settlement under which Entergy Louisiana agreed to provide credits to customers by crediting billings an additional $20.235 million per year for 15 years beginning January 2012. Entergy Louisiana recorded a regulatory charge and a corresponding regulatory liability to reflect this obligation. The settlement agreement allowed for an adjustment to the credits if, among other things, there was a change in the applicable federal or state income tax rate. As a result of the enactment of the Tax Cuts and Jobs Act, in December 2017, and the lowering of the federal corporate income tax rate from 35% to 21%, the Vidalia purchased power regulatory liability was reduced by $30.5 million, with a corresponding increase to Other regulatory credits on the income statement. See Note 3 to the financial statements for discussion of the effects of the Tax Cuts and Jobs Act and discussion of the resolution of the 2016-2018 IRS audit, which included the tax treatment of the Vidalia contract. ANO Damage, Outage, and NRC Reviews In March 2013, during a scheduled refueling outage at ANO 1, a contractor-owned and operated heavy-lifting apparatus collapsed while moving the generator stator out of the turbine building. The collapse resulted in the death of an ironworker and injuries to several other contract workers, caused ANO 2 to shut down, and damaged the ANO turbine building. The total cost of assessment, restoration of off-site power, site restoration, debris removal, and replacement of damaged property and equipment was approximately $95 million. Entergy Arkansas pursued its options for recovering damages that resulted from the stator drop, including its insurance coverage and legal action. Entergy Arkansas collected $50 million in 2014 from Nuclear Electric Insurance Limited (NEIL), a mutual insurance company that provides property damage coverage to the members’ nuclear generating plants. Entergy Arkansas also collected a total of $21 million in 2018 as a result of stator-related settlements. In addition, Entergy Arkansas incurred replacement power costs for ANO 2 power during its outage and incurred incremental replacement power costs for ANO 1 power because the outage extended beyond the originally-planned duration of the refueling outage. In February 2014 the APSC authorized Entergy Arkansas to retain $65.9 million in its deferred fuel balance with recovery to be reviewed in a later period after more information regarding various claims associated with the ANO stator incident was available. In March 2015, after several NRC inspections and regulatory conferences, arising from the stator incident, the NRC placed ANO into the “multiple/repetitive degraded cornerstone column,” or Column 4, of the NRC’s Reactor Oversight Process Action Matrix. Entergy Arkansas incurred incremental costs of approximately $53 million in 2015 to prepare for the NRC inspections that began in early 2016 in order to address the issues required to move ANO back to “licensee response” or Column 1 of the NRC’s Reactor Oversight Process Action Matrix. Excluding remediation and response costs that resulted from the additional NRC inspection activities, Entergy Arkansas incurred approximately $44 million in 2016 and $7 million in 2017 in support of NRC inspection activities and to implement Entergy Arkansas’s performance improvement initiatives developed in 2015. In June 2018 the NRC moved ANO 1 and 2 into the “licensee response column,” or Column 1, of the NRC’s Reactor Oversight Process Action Matrix. In October 2023, Entergy Arkansas made a commitment to the APSC to make a filing to forgo its opportunity to seek recovery of the identified costs resulting from the ANO stator incident, specifically all incremental fuel and purchased energy expense, capital and incremental non-fuel operations and maintenance costs, and costs of any judgment that may be rendered against Entergy Arkansas in civil litigation that is not covered by insurance. As a result, in third quarter 2023, Entergy Arkansas recorded write-offs of its regulatory asset for deferred fuel of $68.9 million, which includes interest, and the undepreciated balance of $9.5 million in capital costs related to the ANO stator incident. Consistent with its October 2023 commitment, Entergy Arkansas filed a motion to forgo recovery in November 2023, and the motion was approved by the APSC in December 2023. Spent Nuclear Fuel Litigation Under the Nuclear Waste Policy Act of 1982, the DOE is required, for a specified fee, to construct storage facilities for, and to dispose of, all spent nuclear fuel and other high-level radioactive waste generated by domestic nuclear power reactors. Entergy’s nuclear owner/licensee subsidiaries have been charged fees for the estimated future disposal costs of spent nuclear fuel in accordance with the Nuclear Waste Policy Act of 1982. The affected Entergy companies entered into contracts with the DOE, whereby the DOE is to furnish disposal services at a cost of one mill per net kWh generated and sold after April 7, 1983, plus a one-time fee for generation prior to that date. Entergy considers all costs incurred for the disposal of spent nuclear fuel, except accrued interest, to be proper components of nuclear fuel expense. Provisions to recover such costs have been or will be made in applications to regulatory authorities for the Utility plants. Following the defunding of the Yucca Mountain spent fuel repository program, the National Association of Regulatory Utility Commissioners and others sued the government seeking cessation of collection of the one mill per net kWh generated and sold after April 7, 1983 fee. In November 2013 the D.C. Circuit ordered the DOE to submit a proposal to Congress to reset the fee to zero until the DOE complies with the Nuclear Waste Policy Act or Congress enacts an alternative waste disposal plan. In January 2014 the DOE submitted the proposal to Congress under protest, and also filed a petition for rehearing with the D.C. Circuit. The petition for rehearing was denied. The zero spent fuel fee went into effect prospectively in May 2014. Because the DOE has not begun accepting spent fuel, it is in non-compliance with the Nuclear Waste Policy Act of 1982 and is in partial breach of its spent fuel disposal contracts. As a result of the DOE’s failure to begin disposal of spent nuclear fuel in 1998 pursuant to the Nuclear Waste Policy Act of 1982 and the spent fuel disposal contracts, Entergy’s nuclear owner/licensee subsidiaries have incurred and will continue to incur damages. Beginning in November 2003 these subsidiaries have pursued litigation to recover the damages caused by the DOE’s delay in performance. Following are details of final judgments recorded by Entergy in 2022, 2023, and 2024 related to Entergy’s nuclear owner/licensee subsidiaries’ litigation with the DOE. In October 2021 the U.S. Court of Federal Claims issued a final judgment in the amount of $83 million in favor of Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC against the DOE in the Indian Point 2 third round and Indian Point 3 second round combined damages case. Entergy received payment from the U.S. Treasury in January 2022. The effect in 2021 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $32 million related to costs previously recorded as plant, $47 million related to costs previously recorded as other operation and maintenance expenses, and $4 million related to costs previously recorded as taxes other than income taxes. In March 2023 the DOE submitted an offer of judgment to resolve claims in the fourth round ANO damages case. The $41 million offer was accepted by Entergy Arkansas, and the U.S. Court of Federal Claims issued a judgment in that amount in favor of Entergy Arkansas and against the DOE. Entergy Arkansas received payment from the U.S. Treasury in April 2023. The effects of recording the judgment were reductions to plant, nuclear fuel expense, other operation and maintenance expenses, materials and supplies, and taxes other than income taxes. The ANO damages awarded included $18 million related to costs previously recorded as plant, $10 million related to costs previously recorded as other operation and maintenance expenses, $8 million related to costs previously recorded as nuclear fuel expense, $3 million related to costs previously recorded as materials and supplies, and $2 million related to costs previously recorded as taxes other than income taxes. In July 2023 the DOE submitted an offer of judgment to resolve claims in the Indian Point 2 fourth round and Indian Point 3 third round combined damages case. The $59 million offer was accepted by Entergy and Holtec International, as the current owner. The U.S. Court of Federal Claims issued a final judgment in that amount in favor of Holtec Indian Point 2, LLC and Holtec Indian Point 3, LLC (previously Entergy Nuclear Indian Point 2, LLC and Entergy Nuclear Indian Point 3, LLC) and against the DOE. Holtec received payment from the U.S. Treasury in July 2023. Consistent with certain terms agreed upon in connection with the sale of Indian Point Energy Center in May 2021, Holtec transferred $40 million to Entergy for its pro-rata share of the litigation proceeds in August 2023. The remainder of the judgment was retained by Holtec. The effect of recording Entergy’s pro-rata share of the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Entergy’s pro-rata share of the damages awarded included $18 million related to costs previously recorded as spending on the asset retirement obligation, $15 million related to costs previously recorded as other operation and maintenance expenses, $6 million related to costs previously recorded as plant, and $1 million related to costs previously recorded as taxes other than income taxes. In August 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $177 million in favor of Northstar Vermont Yankee, LLC (previously Entergy Nuclear Vermont Yankee) and against the DOE in the final round Vermont Yankee damages case. Northstar, as the current owner, received payment from the U.S. Treasury in November 2024 and subsequently transferred $127 million of the litigation proceeds to Entergy per the terms of the agreement for the disposition of Vermont Yankee, which included $107 million for independent spent fuel storage installation expansion, and related to a long-term note receivable issued to Entergy at the time of the disposition of Vermont Yankee, and $20 million for costs related to independent spent fuel storage installation operations, both as required by the disposition documents. Northstar retained $10 million of the litigation proceeds, and the remaining $40 million of the total litigation proceeds was placed by Northstar into an escrow account and is expected to be transferred to Entergy upon the satisfaction of certain agreed upon conditions. The effect of recording Entergy’s share of the judgment was a reduction of $82 million in principle and $25 million in accrued interest on the long-term note receivable and a reduction to asset write-offs, impairments, and related charges (credits) of $20 million related to costs previously recorded as spending on the asset retirement obligation. In October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Payment to Holtec, as the current owner, from the U.S. Treasury is expected in first quarter 2025, at which time Holtec is expected to transfer the $7 million judgment to Entergy. The effect of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). Management cannot predict the timing or amount of any potential recoveries on other claims filed by Entergy subsidiaries and cannot predict the timing of any eventual receipt from the DOE of the U.S. Court of Federal Claims damage awards. Nuclear Insurance Third Party Liability Insurance The Price-Anderson Act requires that reactor licensees purchase insurance and participate in a secondary insurance pool that provides insurance coverage for the public in the event of a nuclear power plant accident. The costs of this insurance are borne by the nuclear power industry. Congress amended and renewed the Price-Anderson Act in 2024 for a term through 2065. The Price-Anderson Act requires nuclear power plants to show evidence of financial protection in the event of a nuclear accident. This protection must consist of two layers of coverage: 1. The primary level is i nsurance underwritten by American Nuclear Insurers (ANI) and provides public liability insurance coverage of $500 million for each operating reactor. If this amount is not sufficient to cover claims arising from an accident, the second level, Secondary Financial Protection, applies. 2. Secondary Financial Protection: Curr ently, 95 nuclear reactors participate in the Secondary Financial Protection program, which provides approximately $15.8 billion in secondary layer insurance coverage to compensate the public in the event of a nuclear power reactor accident. The Price-Anderson Act provides that all potential liability for a nuclear accident is limited to the amounts of insurance coverage available under the primary and secondary layers. Within the Secondary Financial Protection program, each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident or fault, up to a maxi mum of approximately $165.9 million per reactor per incident (Entergy’s maximum total contingent obligation per incident is $829.6 million). This retrospective premium is assessable at approximately $24.7 million per year per incident per nuclear power reactor. 3. Total insurance coverage available is approximately $16.3 billion, among the primary ANI coverage and the Secondary Financial Protection program, to respond to a nuclear power plant accident that causes third-party damages (e.g., off-site property and environmental damage, off-site bodily injury, and on-site third-party bodily injury (i.e., contractors)). These coverages also respond to an accident caused by terrorism. Entergy Arkansas and Entergy Louisiana each have two licensed reactors. System Energy has one licensed reactor (10% of Grand Gulf is owned by a non-affiliated company (Cooperative Energy) that would share on a pro-rata basis in any retrospective premium assessment to System Energy under the Price-Anderson Act). Property Insurance Entergy’s nuclear owner/licensee subsidiaries are members of NEIL, a mutual insurance company that provides property damage coverage, including decontamination and reactor stabilization, to the members’ nuclear generating plants. The property damage insurance limits procured by Entergy for its nuclear plants are in compliance with the financial protection requirements of the NRC. These coverage limits, deductibles, and weekly indemnity periods are subject to change based on results of NEIL loss control inspections. The nuclear plants’ (ANO 1 and 2, Grand Gulf, River Bend, and Waterford 3) property damage insurance limits are $1.06 billion per occurrence at each plant. The property deductible is $20 million per site at the nuclear plants, except for earth movement, flood, and windstorm. Property damage from earth movement is excluded from the first $500 million in coverage for all nuclear plants. Property damage from flood is excluded from the first $500 million in coverage at ANO 1 and 2 and Grand Gulf. Property damage from flood for Waterford 3 and River Bend includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a maximum deductible of $50 million. Property damage from a windstorm for all of the nuclear plants includes a deductible of $10 million plus an additional 10% of the amount of the loss in excess of $10 million, up to a total maximum deductible of $50 million. In addition, Waterford 3 and Entergy’s portion of Grand Gulf are also covered under NEIL’s Accidental Outage Coverage program. Accidental outage coverage provides indemnification for the actual cost incurred in the event of an unplanned outage resulting from property damage covered under the NEIL Primary Property Insurance policy, subject to a deductible period. The indemnification is based on market power prices at the time of the loss, actual costs incurred during the outage, and the respective limits of each nuclear plant. After the deductible period has passed, weekly indemnities for an unplanned nuclear or non-nuclear outage, covered under NEIL’s Accidental Outage Coverage program, would be paid according to the amounts listed below: • 100% of the weekly indemnity for each week for the initial payment period of 52 weeks for nuclear and non-nuclear loss; then • 80% of the weekly indemnity for each week for the final payment period of 110 weeks for nuclear loss only; or • 60% of the weekly indemnity for each week for the final payment period of 52 weeks for non-nuclear loss only. Under the property damage and accidental outage insurance programs, all NEIL insured plants could be subject to assessments should losses exceed the accumulated funds available from NEIL. The assessments are subject to change based on results of NEIL underwriting. The current maximum amounts of such possible assessments per occurrence are as follows: Assessments (In Millions) Entergy Arkansas $20.0 Entergy Louisiana $37.6 Entergy Mississippi $0.1 Entergy New Orleans $0.1 Entergy Texas N/A System Energy $14.4 NRC regulations provide that the proceeds of this insurance must be used, first, to render the reactor safe and stable, and second, to complete decontamination operations. Only after proceeds are dedicated for such use and regulatory approval is secured would any remaining proceeds be made available for the benefit of plant owners or their creditors. In the event that one or more acts of terrorism causes property damage from a nuclear event under one or more or all nuclear insurance policies issued by NEIL (including, but not limited to, those described above) within 12 months from the date the first property damage occurs, the maximum recovery under all such nuclear insurance policies shall be an aggregate not exceedi ng $3.24 billion plus the additional amounts recovered for such losses from reinsurance, indemnity, and any other sources applicable to such losses. Non-Nuclear Property Insurance Entergy’s non-nuclear property insurance program provides coverage on a system-wide basis for Entergy’s non-nuclear assets. The insurance program provides coverage for property damage up to $400 million per occurrence in excess of a $20 million self-insured retention except for property damage caused by the following: earthquake shock, flood, and named windstorm, including associated storm surge. For earthquake shock and flood, the insurance program provides coverage up to $400 million on an annual aggregate basis in excess of a $40 million self-insured retention. For named windstorm and associated storm surge, the insurance program provides coverage up to $125 million on an annual aggregate basis in excess of a $40 million self-insured retention. The coverage provided by the insurance program for the Entergy New Orleans gas distribution system is limited to $50 million per occurrence and is subject to the same annual aggregate limits and retentions listed above for earthquake shock, flood, and named windstorm, including associated storm surge. Covered property generally includes power plants, substations, facilities, inventories, and gas distribution-related properties. Excluded property generally includes transmission and distribution lines, poles, and towers. For substations valued at $5 million or less, coverage for named windstorm and associated storm surge is excluded. This coverage is in place for Entergy Corporation, the Registrant Subsidiaries, and certain other Entergy subsidiaries. Entergy also purchases $400 million in terrorism insurance coverage for its conventional property. Employment and Labor-related Proceedings The Registrant Subsidiaries and other Entergy subsidiaries and related entities are responding to various lawsuits in both state and federal courts and to other labor-related proceedings filed by current and former employees, recognized bargaining representatives, and certain third parties. Generally, the amount of damages being sought is not specified in these proceedings. These actions may include, but are not limited to, allegations of wrongful employment actions; wage disputes and other claims under the Fair Labor Standards Act or its state counterparts; claims of race, gender, age, and disability discrimination; disputes arising under collective bargaining agreements; unfair labor practice proceedings and other administrative proceedings before the National Labor Relations Board or concerning the National Labor Relations Act; claims of retaliation; claims of harassment and hostile work environment; and claims for or regarding benefits under various Entergy Corporation-sponsored employee benefit plans. Entergy and the Registrant Subsidiaries and related entities are responding to these lawsuits and proceedings and deny liability to the claimants. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of Entergy or the Registrant Subsidiaries. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) Numerous lawsuits have been filed in state courts against primarily Entergy Louisiana and Entergy Texas by individuals alleging exposure to asbestos while working at Entergy facilities between 1955 and 1980. Entergy is being sued as a premises owner. Many other defendants are named in these lawsuits as well. Currently, there are approximately 185 lawsuits involving approximately 330 claimants. Management believes that adequate provisions have been established to cover any exposure. Additionally, negotiations continue with insurers to recover reimbursements. Management believes that loss exposure has been and will continue to be handled so that the ultimate resolution of these matters will not be material, in the aggregate, to the financial position, results of operation, or cash flows of the Utility operating companies. Grand Gulf-Related Agreements Unit Power Sales Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy sells all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. Charges under this agreement are paid in consideration for the purchasing companies’ respective entitlement to receive capacity and energy and are payable irrespective of the quantity of energy delivered. Grand Gulf’s operating license currently extends through 2044. Monthly obligations are based on actual capacity and energy costs. The average monthly payments for 2024 under the agreement were approximately $16.8 million for Entergy Arkansas, $7.0 million for Entergy Louisiana, $16.4 million for Entergy Mississippi, and $8.4 million for Entergy New Orleans. See Note 2 to the financial statements for discussion of proceedings regarding the Unit Power Sales Agreement.

See Note 2 to the financial statements for discussion of the System Energy settlement with the LPSC. Availability Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans are individually obligated to make payments or subordinated advances to System Energy in accordance with stated percentages (Entergy Arkansas - 17.1%, Entergy Louisiana - 26.9%, Entergy Mississippi - 31.3%, and Entergy New Orleans - 24.7%) in amounts that, when added to amounts received under the Unit Power Sales Agreement or otherwise, are adequate to cover all of System Energy’s operating expenses as defined, including expenses incurred in connection with a permanent shutdown of Grand Gulf. System Energy has assigned its rights to payments and advances to certain creditors as security for certain of its debt obligations. Since commercial operation of Grand Gulf began, payments under the Unit Power Sales Agreement to System Energy have exceeded the amounts payable under the Availability Agreement and, therefore, no payments under the Availability Agreement have ever been required. However, if Entergy Arkansas or Entergy Mississippi fails to make its Unit Power Sales Agreement payments, and System Energy is unable to obtain funds from other sources, Entergy Louisiana and Entergy New Orleans could become subject to claims or demands by System Energy or certain of its creditors for payments or advances under the Availability Agreement (or the assignments thereof) equal to the difference between their required Unit Power Sales Agreement payments and their required Availability Agreement payments because their allocated shares under the Availability Agreement exceed their allocated shares under the Unit Power Sales Agreement. Under the Entergy Louisiana divestiture described in “ Unit Power Sales Agreement ” above, Entergy Mississippi assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and will hold Entergy Louisiana harmless with respect thereto, effective as of January 1, 2025. Reallocation Agreement (Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and System Energy) System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans entered into the Reallocation Agreement relating to the sale of capacity and energy from Grand Gulf and the related costs, in which Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans agreed to assume all of Entergy Arkansas’s responsibilities and obligations with respect to Grand Gulf under the Availability Agreement. The FERC’s decision allocating a portion of Grand Gulf capacity and energy to Entergy Arkansas supersedes the Reallocation Agreement as it relates to Grand Gulf. Effective December 2024, the parties terminated the Reallocation Agreement.

Asset Retirement Obligations

Asset Retirement Obligations	12 Months Ended

Asset Retirement Obligation Disclosure [Text Block]	ASSET RETIREMENT OBLIGATIONS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Accounting standards require companies to record liabilities for all legal obligations associated with the retirement of long-lived assets that result from the normal operation of the assets. For Entergy, substantially all of its asset retirement obligations consist of its liability for decommissioning its nuclear power plants. The remainder of removal costs included in the decommissioning and asset retirement costs line item on the balance sheets is associated with non-nuclear power plants. These liabilities are recorded at their fair values (which are the present values of the estimated future cash outflows) in the period in which they are incurred, with an accompanying addition to the recorded cost of the long-lived asset. The asset retirement obligation is accreted each year through a charge to expense, to reflect the time value of money for this present value obligation. The accretion will continue through the completion of the asset retirement activity. The amounts added to the carrying amounts of the long-lived assets will be depreciated over the useful lives of the assets. The application of accounting standards related to asset retirement obligations is earnings neutral to the rate-regulated business of the Registrant Subsidiaries. In accordance with ratemaking treatment and as required by regulatory accounting standards, the depreciation provisions for the Registrant Subsidiaries include a component for removal costs that are not asset retirement obligations under accounting standards. In accordance with regulatory accounting principles, the Registrant Subsidiaries have recorded regulatory assets in the following amounts to reflect their estimates of the difference between estimated incurred removal costs and estimated removal costs expected to be recovered in rates: December 31, 2024 2023 (In Millions) Entergy Arkansas $337.9 $319.7 Entergy Louisiana $323.2 $262.3 Entergy Mississippi $184.8 $188.0 Entergy New Orleans $62.5 $61.1 Entergy Texas $102.3 $77.5 System Energy $96.9 $102.1 As of December 31, 2024, the regulatory asset for removal costs for the Utility operating companies includes amounts related to storm restoration costs. See Note 2 to the financial statements for further discussion of storm restoration costs and requested recovery. The cumulative decommissioning and retirement cost liabilities and expenses recorded in 2024 and 2023 for Entergy and the Registrant Subsidiaries were as follows: Entergy Entergy Entergy Entergy Entergy Entergy System Energy (In Millions) Liabilities as of December 31, 2022 $4,271.5 $1,472.7 $1,736.8 $7.8 $— $11.1 $1,042.5 Accretion 219.4 87.4 88.6 0.4 0.5 0.6 41.7 Change in cash flow estimate 14.9 — 10.8 — 4.1 — — Liabilities as of December 31, 2023 4,505.8 1,560.1 1,836.2 8.2 4.6 11.7 1,084.2 Liabilities incurred (a) 41.1 17.7 19.4 4.0 — — — Accretion 233.8 93.6 94.4 1.1 0.3 0.8 43.5 Change in cash flow estimate (67.3) 20.2 (107.1) 11.8 — 5.2 — Liabilities as of December 31, 2024 $4,713.4 $1,691.6 $1,842.9 $25.1 $4.9 $17.7 $1,127.7 (a) See “ Other ” below for additional discussion regarding the asset retirement obligations established at Entergy Arkansas, Entergy Louisiana, and Entergy Mississippi. Nuclear Plant Decommissioning Entergy periodically reviews and updates estimated decommissioning costs. The actual decommissioning costs may vary from the estimates because of the timing of plant decommissioning, regulatory requirements, changes in technology, and increased costs of labor, materials, and equipment. In first quarter 2024, Entergy Arkansas recorded a revision to its estimated decommissioning cost liabilities for ANO 1 and 2 as a result of a revised decommissioning cost study. The revised estimates resulted in a $14.4 million decrease in its decommissioning cost liabilities, along with corresponding decreases in the related asset retirement cost assets that will be depreciated over the remaining useful lives of the units. In fourth quarter 2024, Entergy Louisiana recorded a revision to its estimated decommissioning cost liability for Waterford 3 as a result of a revised decommissioning cost study. The revised estimate resulted in a $121.5 million decrease in its decommissioning cost liability, along with a corresponding decrease in the related asset retirement cost asset that will be depreciated over the remaining useful life of the unit. In third quarter 2023, Entergy Louisiana recorded a revision to its estimated decommissioning cost liability for River Bend as a result of a revised decommissioning cost study. The revised estimate resulted in a $10.8 million increase in its decommissioning cost liability, along with a corresponding increase in the related asset retirement cost asset that will be depreciated over the remaining useful life of the unit. NRC Filings Regarding Trust Funding Levels Plant owners are required to provide the NRC with a biennial report (annually for units that have shut down or will shut down within five years), based on values as of December 31, addressing the owners’ ability to meet the NRC minimum funding levels. Depending on the value of the trust funds, plant owners may be required to take steps, such as providing financial guarantees through letters of credit or parent company guarantees or making additional contributions to the trusts, to ensure that the trusts are adequately funded and that NRC minimum funding requirements are met. As nuclear plants individually approach and begin decommissioning, filings will be submitted to the NRC for planned shutdown activities. These filings with the NRC also determine whether financial assurance may be required in addition to the nuclear decommissioning trust fund. Coal Combustion Residuals In April 2015 the EPA published the final coal combustion residuals (CCR) rule regulating CCRs destined for disposal in landfills or surface impoundments as non-hazardous wastes regulated under Resource Conservation and Recovery Act Subtitle D. The final regulations create new compliance requirements including modified storage, new notification and reporting practices, product disposal considerations, and CCR unit closure criteria, but excluded CCRs that are beneficially reused in certain processes. Entergy believes that on-site disposal options will be available at its facilities, to the extent needed. In second quarter 2024, revisions were recorded to the estimated decommissioning cost liabilities for White Bluff and Independence as a result of the EPA rule that was finalized in May 2024 establishing management standards for legacy CCR surface impoundments (i.e., inactive surface impoundments at inactive power plants) and establishing a new class of units referred to as CCR management units (CCRMUs) (i.e., non-containerized CCR located at a regulated CCR facility). Entergy does not have any legacy impoundments; however, the definition of CCR management units includes on-site areas where CCR was beneficially used. This is contrary to the previous CCR rule which exempted beneficial uses that met certain criteria. Under this expanded rule, all facilities must identify and delineate any CCRMU greater than one ton and submit a facility evaluation report by February 2026. Any potential requirements for corrective action or operational changes under the various CCR rules continue to be assessed. Given the complexity and recency of the EPA guidance, Entergy is still evaluating the level of work that will ultimately be required to comply with the rule. Based on initial estimates of multiple possible remediation scenarios, Entergy Arkansas and Entergy Mississippi recorded increases of $31.2 million and $9.1 million, respectively, in their decommissioning cost liabilities, along with corresponding increases in the related asset retirement cost assets that will be depreciated over the remaining useful lives of the units. Entergy will continue to update the asset retirement obligation as the requirements of the revised CCR rule are clarified. Other In 2024, Entergy Mississippi recorded an asset retirement obligation to reflect decommissioning costs related to an obligation under the Sunflower Solar facility’s land lease agreements to remove the electrical system and return the land to its normal condition. This estimate resulted in the establishment of a $4.0 million decommissioning cost liability, along with the establishment of a related asset retirement cost asset that will be depreciated over the remaining initial lease term. See Note 14 to the financial statements for discussion of Entergy Mississippi’s purchase of the Sunflower Solar facility. In 2024, Entergy Arkansas recorded asset retirement obligations to reflect decommissioning costs related to obligations to remove the electrical systems and return the land to its normal condition under the respective land lease agreements for the Walnut Bend Solar facility and the Driver Solar facility. These estimates resulted in the establishment of a decommissioning cost liability of $4.5 million for the Walnut Bend Solar facility and of $13.2 million for the Driver Solar facility, along with the establishment of related asset retirement cost assets that will be depreciated over the remaining initial lease terms, respectively. See Note 14 to the financial statements for discussion of Entergy Arkansas’s purchase of the Walnut Bend Solar facility and the Driver Solar facility. Prior to August 2024, Entergy Louisiana was a partner in the Nelson Industrial Steam Company (NISCO) partnership which owned two petroleum coke generating units. In April 2023 these generating units suspended operations in the MISO market, and the parties to the NISCO partnership began working to wind up the NISCO partnership, which would ultimately result in ownership of the generating units transferring to Entergy Louisiana. In November 2023 the FERC issued an order providing Section 203 of the Federal Power Act approval for any subsequent transfer of the facilities to Entergy Louisiana. In August 2024, Entergy Louisiana and its partners in the NISCO partnership entered into an agreement related to the wind up of the partnership, which resulted in the receipt of $21.3 million in cash by Entergy Louisiana and the transfer of ownership of the non-operating facilities to Entergy Louisiana. As a result of the agreement and resulting transfer of ownership, Entergy Louisiana also recognized an asset retirement obligation of $19.4 million associated with the ash landfill area in 2024.

Nuclear Plant Decommissioning Entergy periodically reviews and updates estimated decommissioning costs. The actual decommissioning costs may vary from the estimates because of the timing of plant decommissioning, regulatory requirements, changes in technology, and increased costs of labor, materials, and equipment. In first quarter 2024, Entergy Arkansas recorded a revision to its estimated decommissioning cost liabilities for ANO 1 and 2 as a result of a revised decommissioning cost study. The revised estimates resulted in a $14.4 million decrease in its decommissioning cost liabilities, along with corresponding decreases in the related asset retirement cost assets that will be depreciated over the remaining useful lives of the units. In fourth quarter 2024, Entergy Louisiana recorded a revision to its estimated decommissioning cost liability for Waterford 3 as a result of a revised decommissioning cost study. The revised estimate resulted in a $121.5 million decrease in its decommissioning cost liability, along with a corresponding decrease in the related asset retirement cost asset that will be depreciated over the remaining useful life of the unit. In third quarter 2023, Entergy Louisiana recorded a revision to its estimated decommissioning cost liability for River Bend as a result of a revised decommissioning cost study. The revised estimate resulted in a $10.8 million increase in its decommissioning cost liability, along with a corresponding increase in the related asset retirement cost asset that will be depreciated over the remaining useful life of the unit. NRC Filings Regarding Trust Funding Levels Plant owners are required to provide the NRC with a biennial report (annually for units that have shut down or will shut down within five years), based on values as of December 31, addressing the owners’ ability to meet the NRC minimum funding levels. Depending on the value of the trust funds, plant owners may be required to take steps, such as providing financial guarantees through letters of credit or parent company guarantees or making additional contributions to the trusts, to ensure that the trusts are adequately funded and that NRC minimum funding requirements are met. As nuclear plants individually approach and begin decommissioning, filings will be submitted to the NRC for planned shutdown activities. These filings with the NRC also determine whether financial assurance may be required in addition to the nuclear decommissioning trust fund. Coal Combustion Residuals In April 2015 the EPA published the final coal combustion residuals (CCR) rule regulating CCRs destined for disposal in landfills or surface impoundments as non-hazardous wastes regulated under Resource Conservation and Recovery Act Subtitle D. The final regulations create new compliance requirements including modified storage, new notification and reporting practices, product disposal considerations, and CCR unit closure criteria, but excluded CCRs that are beneficially reused in certain processes. Entergy believes that on-site disposal options will be available at its facilities, to the extent needed. In second quarter 2024, revisions were recorded to the estimated decommissioning cost liabilities for White Bluff and Independence as a result of the EPA rule that was finalized in May 2024 establishing management standards for legacy CCR surface impoundments (i.e., inactive surface impoundments at inactive power plants) and establishing a new class of units referred to as CCR management units (CCRMUs) (i.e., non-containerized CCR located at a regulated CCR facility). Entergy does not have any legacy impoundments; however, the definition of CCR management units includes on-site areas where CCR was beneficially used. This is contrary to the previous CCR rule which exempted beneficial uses that met certain criteria. Under this expanded rule, all facilities must identify and delineate any CCRMU greater than one ton and submit a facility evaluation report by February 2026. Any potential requirements for corrective action or operational changes under the various CCR rules continue to be assessed. Given the complexity and recency of the EPA guidance, Entergy is still evaluating the level of work that will ultimately be required to comply with the rule. Based on initial estimates of multiple possible remediation scenarios, Entergy Arkansas and Entergy Mississippi recorded increases of $31.2 million and $9.1 million, respectively, in their decommissioning cost liabilities, along with corresponding increases in the related asset retirement cost assets that will be depreciated over the remaining useful lives of the units. Entergy will continue to update the asset retirement obligation as the requirements of the revised CCR rule are clarified. Other In 2024, Entergy Mississippi recorded an asset retirement obligation to reflect decommissioning costs related to an obligation under the Sunflower Solar facility’s land lease agreements to remove the electrical system and return the land to its normal condition. This estimate resulted in the establishment of a $4.0 million decommissioning cost liability, along with the establishment of a related asset retirement cost asset that will be depreciated over the remaining initial lease term. See Note 14 to the financial statements for discussion of Entergy Mississippi’s purchase of the Sunflower Solar facility. In 2024, Entergy Arkansas recorded asset retirement obligations to reflect decommissioning costs related to obligations to remove the electrical systems and return the land to its normal condition under the respective land lease agreements for the Walnut Bend Solar facility and the Driver Solar facility. These estimates resulted in the establishment of a decommissioning cost liability of $4.5 million for the Walnut Bend Solar facility and of $13.2 million for the Driver Solar facility, along with the establishment of related asset retirement cost assets that will be depreciated over the remaining initial lease terms, respectively. See Note 14 to the financial statements for discussion of Entergy Arkansas’s purchase of the Walnut Bend Solar facility and the Driver Solar facility. Prior to August 2024, Entergy Louisiana was a partner in the Nelson Industrial Steam Company (NISCO) partnership which owned two petroleum coke generating units. In April 2023 these generating units suspended operations in the MISO market, and the parties to the NISCO partnership began working to wind up the NISCO partnership, which would ultimately result in ownership of the generating units transferring to Entergy Louisiana. In November 2023 the FERC issued an order providing Section 203 of the Federal Power Act approval for any subsequent transfer of the facilities to Entergy Louisiana. In August 2024, Entergy Louisiana and its partners in the NISCO partnership entered into an agreement related to the wind up of the partnership, which resulted in the receipt of $21.3 million in cash by Entergy Louisiana and the transfer of ownership of the non-operating facilities to Entergy Louisiana. As a result of the agreement and resulting transfer of ownership, Entergy Louisiana also recognized an asset retirement obligation of $19.4 million associated with the ash landfill area in 2024.

Asset Retirement Obligation Disclosure [Text Block]	ASSET RETIREMENT OBLIGATIONS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Accounting standards require companies to record liabilities for all legal obligations associated with the retirement of long-lived assets that result from the normal operation of the assets. For Entergy, substantially all of its asset retirement obligations consist of its liability for decommissioning its nuclear power plants. The remainder of removal costs included in the decommissioning and asset retirement costs line item on the balance sheets is associated with non-nuclear power plants. These liabilities are recorded at their fair values (which are the present values of the estimated future cash outflows) in the period in which they are incurred, with an accompanying addition to the recorded cost of the long-lived asset. The asset retirement obligation is accreted each year through a charge to expense, to reflect the time value of money for this present value obligation. The accretion will continue through the completion of the asset retirement activity.

The revised estimate resulted in a $10.8 million increase in its decommissioning cost liability, along with a corresponding increase in the related asset retirement cost asset that will be depreciated over the remaining useful life of the unit. NRC Filings Regarding Trust Funding Levels Plant owners are required to provide the NRC with a biennial report (annually for units that have shut down or will shut down within five years), based on values as of December 31, addressing the owners’ ability to meet the NRC minimum funding levels. Depending on the value of the trust funds, plant owners may be required to take steps, such as providing financial guarantees through letters of credit or parent company guarantees or making additional contributions to the trusts, to ensure that the trusts are adequately funded and that NRC minimum funding requirements are met. As nuclear plants individually approach and begin decommissioning, filings will be submitted to the NRC for planned shutdown activities. These filings with the NRC also determine whether financial assurance may be required in addition to the nuclear decommissioning trust fund. Coal Combustion Residuals In April 2015 the EPA published the final coal combustion residuals (CCR) rule regulating CCRs destined for disposal in landfills or surface impoundments as non-hazardous wastes regulated under Resource Conservation and Recovery Act Subtitle D. The final regulations create new compliance requirements including modified storage, new notification and reporting practices, product disposal considerations, and CCR unit closure criteria, but excluded CCRs that are beneficially reused in certain processes. Entergy believes that on-site disposal options will be available at its facilities, to the extent needed. In second quarter 2024, revisions were recorded to the estimated decommissioning cost liabilities for White Bluff and Independence as a result of the EPA rule that was finalized in May 2024 establishing management standards for legacy CCR surface impoundments (i.e., inactive surface impoundments at inactive power plants) and establishing a new class of units referred to as CCR management units (CCRMUs) (i.e., non-containerized CCR located at a regulated CCR facility). Entergy does not have any legacy impoundments; however, the definition of CCR management units includes on-site areas where CCR was beneficially used. This is contrary to the previous CCR rule which exempted beneficial uses that met certain criteria. Under this expanded rule, all facilities must identify and delineate any CCRMU greater than one ton and submit a facility evaluation report by February 2026. Any potential requirements for corrective action or operational changes under the various CCR rules continue to be assessed. Given the complexity and recency of the EPA guidance, Entergy is still evaluating the level of work that will ultimately be required to comply with the rule. Based on initial estimates of multiple possible remediation scenarios, Entergy Arkansas and Entergy Mississippi recorded increases of $31.2 million and $9.1 million, respectively, in their decommissioning cost liabilities, along with corresponding increases in the related asset retirement cost assets that will be depreciated over the remaining useful lives of the units. Entergy will continue to update the asset retirement obligation as the requirements of the revised CCR rule are clarified. Other In 2024, Entergy Mississippi recorded an asset retirement obligation to reflect decommissioning costs related to an obligation under the Sunflower Solar facility’s land lease agreements to remove the electrical system and return the land to its normal condition. This estimate resulted in the establishment of a $4.0 million decommissioning cost liability, along with the establishment of a related asset retirement cost asset that will be depreciated over the remaining initial lease term. See Note 14 to the financial statements for discussion of Entergy Mississippi’s purchase of the Sunflower Solar facility. In 2024, Entergy Arkansas recorded asset retirement obligations to reflect decommissioning costs related to obligations to remove the electrical systems and return the land to its normal condition under the respective land lease agreements for the Walnut Bend Solar facility and the Driver Solar facility. These estimates resulted in the establishment of a decommissioning cost liability of $4.5 million for the Walnut Bend Solar facility and of $13.2 million for the Driver Solar facility, along with the establishment of related asset retirement cost assets that will be depreciated over the remaining initial lease terms, respectively. See Note 14 to the financial statements for discussion of Entergy Arkansas’s purchase of the Walnut Bend Solar facility and the Driver Solar facility. Prior to August 2024, Entergy Louisiana was a partner in the Nelson Industrial Steam Company (NISCO) partnership which owned two petroleum coke generating units. In April 2023 these generating units suspended operations in the MISO market, and the parties to the NISCO partnership began working to wind up the NISCO partnership, which would ultimately result in ownership of the generating units transferring to Entergy Louisiana. In November 2023 the FERC issued an order providing Section 203 of the Federal Power Act approval for any subsequent transfer of the facilities to Entergy Louisiana. In August 2024, Entergy Louisiana and its partners in the NISCO partnership entered into an agreement related to the wind up of the partnership, which resulted in the receipt of $21.3 million in cash by Entergy Louisiana and the transfer of ownership of the non-operating facilities to Entergy Louisiana. As a result of the agreement and resulting transfer of ownership, Entergy Louisiana also recognized an asset retirement obligation of $19.4 million associated with the ash landfill area in 2024.

Retirement Benefits [Text Block]	RETIREMENT, OTHER POSTRETIREMENT BENEFITS, AND DEFINED CONTRIBUTION PLANS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Qualified Pension Plans Entergy has defined benefit qualified pension plans, including the Entergy Corporation Retirement Plan for Non-Bargaining Employees (Non-Bargaining Plan I), the Entergy Corporation Retirement Plan for Bargaining Employees (Bargaining Plan I), the Entergy Corporation Retirement Plan II for Non-Bargaining Employees (Non-Bargaining Plan II), the Entergy Corporation Retirement Plan II for Bargaining Employees (Bargaining Plan II), the Entergy Corporation Retirement Plan III (Plan III), the Entergy Corporation Retirement Plan IV for Bargaining Employees, Entergy Corporation Retirement Plan VI for Non-Bargaining Employees (Non-Bargaining Plan VI), and the Entergy Corporation Cash Balance Plan for Bargaining Employees (Bargaining Cash Balance Plan). The Entergy Corporation Cash Balance Plan for Non-Bargaining Employees (Non-Bargaining Cash Balance Plan) was merged with and into Non-Bargaining Plan I effective January 1, 2022. Effective January 1, 2024, Non-Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Non-Bargaining Plan VI. Effective January 1, 2025, Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Entergy Corporation Plan VI for Bargaining Employees (Bargaining Plan VI). The Bargaining Cash Balance Plan was merged with and into Bargaining Plan I also effective January 1, 2025. The Registrant Subsidiaries participate in these plans: Non-Bargaining Plan I, Bargaining Plan I, Plan III, Non-Bargaining Plan VI, and Bargaining Cash Balance Plan. Non-bargaining and bargaining employees whose most recent date of hire was prior to June 30, 2014 (or such later date provided for in their applicable collective bargaining agreement) participate in a noncontributory final average pay formula that provides pension benefits based on the employee’s credited service and compensation during employment. Non-bargaining and bargaining employees whose most recent date of hire is after June 30, 2014 and before January 1, 2021 (or such later date provided for in their applicable collective bargaining agreement) do not participate in a final average pay formula, but instead participate in a cash balance formula. Effective January 1, 2021, the Non-Bargaining Cash Balance Plan and Bargaining Cash Balance Plan were amended to close participation in each plan to those employees whose most recent hire date is after December 31, 2020 (or such later date provided for in their applicable collective bargaining agreement). Employees hired after this date instead may be eligible to participate in and receive a discretionary employer contribution under an Entergy sponsored tax-qualified defined contribution plan that includes a 401(k) feature. The assets of the defined benefit qualified pension plans are held in a master trust established by Entergy. Each pension plan has an undivided beneficial interest in each of the investment accounts in the master trust that is maintained by a trustee. Use of the master trust permits the commingling of the trust assets of the pension plans of Entergy Corporation and its Registrant Subsidiaries for investment and administrative purposes. Although assets in the master trust are commingled, the trustee maintains supporting records for the purpose of allocating the trust level equity in net earnings (loss) and the administrative expenses of the investment accounts in the trust to the various participating pension plans in the trust. The fair value of the trust’s assets is determined by the trustee and certain investment managers. The trustee calculates a daily earnings factor, including realized and unrealized gains or losses, collected and accrued income, and administrative expenses, and allocates earnings to each plan in the master trust on a pro rata basis. Within each pension plan, the record of each Registrant Subsidiary’s beneficial interest in the plan assets is maintained by the plan’s actuary and is updated quarterly. Assets for each Registrant Subsidiary are increased for investment net income and contributions and are decreased for benefit payments. A plan’s investment net income/loss (i.e., interest and dividends, realized and unrealized gains and losses and expenses) is allocated to the Registrant Subsidiaries participating in that plan based on the value of assets for each Registrant Subsidiary at the beginning of the quarter adjusted for contributions and benefit payments made during the quarter. Entergy Corporation and its subsidiaries fund pension plans in an amount not less than the minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The assets of the plans include common and preferred stocks, fixed-income securities, interest in a money market fund, and insurance contracts. The Registrant Subsidiaries’ pension costs are recovered from customers as a component of cost of service in each of their respective jurisdictions. Components of Qualified Net Pension Cost and Other Amounts Recognized as a Regulatory Asset and/or Accumulated Other Comprehensive Income (AOCI) Entergy Corporation and its subsidiaries’ total 2024, 2023, and 2022 qualified pension costs and amounts recognized as a regulatory asset and/or other comprehensive income, including amounts capitalized, included the following components: 2024 2023 2022 (In Thousands) Net periodic pension cost: Service cost -

The qualified pension plans incurred net actuarial gains during 2024 primarily due to liability gains due to a rise in bond yields that resulted in increases to the discount rates used to develop the benefit obligations; partially offset by asset losses resulting from an actual return on assets lower than the expected return on assets in some plans. The qualified pension plans incurred net actuarial gains during 2023 primarily due to asset gains resulting from an actual return on assets much higher than the expected return on assets, offset by liability losses due to a decline in bond yields that resulted in decreases to the discount rates used to develop the benefit obligations. The accumulated benefit obligation for Entergy’s qualified pension plans was $4.1 billion and $5.6 billion at December 31, 2024 and 2023, respectively.

Employees who commenced employment before July 1, 2014 and who satisfy certain eligibility requirements (including retiring from Entergy after a certain age and/or years of service with Entergy and immediately commencing their Entergy pension benefit), may become eligible for other postretirement benefits. In March 2020, Entergy announced changes to its other postretirement benefits. Effective January 1, 2021, certain retired, former non-bargaining employees age 65 and older who are eligible for Entergy-sponsored retiree welfare benefits, and their eligible spouses who are age 65 and older (collectively, Medicare-eligible participants), are eligible to participate in an Entergy-sponsored retiree health plan, and are no longer eligible for retiree coverage under the Entergy Corporation Companies’ Benefits Plus Medical, Dental and Vision Plans. Under the Entergy-sponsored retiree health plan, Medicare-eligible participants are eligible to participate in a health reimbursement arrangement which they may use towards the purchase of various types of qualified insurance offered through a Medicare exchange provider and for other qualified medical expenses. The changes affecting active bargaining unit employees were negotiated with the unions prior to implementation, where necessary, and to the extent required by law. Effective January 1, 1993, Entergy adopted an accounting standard requiring a change from a cash method to an accrual method of accounting for postretirement benefits other than pensions. Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy have received regulatory approval to recover accrued other postretirement benefits costs through rates. The LPSC ordered Entergy Louisiana to continue the use of the pay-as-you-go method for ratemaking purposes for postretirement benefits other than pensions. However, the LPSC retains the flexibility to examine individual companies’ accounting for other postretirement benefits to determine if special exceptions to this order are warranted. Pursuant to regulatory directives, Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy contribute the other postretirement benefits costs collected in rates into external trusts. System Energy is funding, on behalf of Entergy Operations, other postretirement benefits associated with employees who work or worked at Grand Gulf. Trust assets contributed by participating Registrant Subsidiaries are in master trusts, established by Entergy Corporation and maintained by a trustee. Each plan has an undivided beneficial interest in each of the investment accounts in its respective master trust that is maintained by a trustee. Each participating Registrant Subsidiary holds a beneficial interest in the plans’ investment accounts. The assets in the master trusts are commingled for investment and administrative purposes. Although assets are commingled, supporting records are maintained for the purpose of allocating the beneficial interest in net earnings/(losses) and the administrative expenses of the investment accounts to the various participating plans and participating Registrant Subsidiaries. Beneficial interest in an investment account’s net income/(loss) is comprised of interest and dividends, realized and unrealized gains and losses, and expenses. Beneficial interest from these investments is allocated to the plans and participating Registrant Subsidiary based on their portion of net assets in the pooled accounts.

Retirement Benefits [Text Block]	RETIREMENT, OTHER POSTRETIREMENT BENEFITS, AND DEFINED CONTRIBUTION PLANS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Qualified Pension Plans Entergy has defined benefit qualified pension plans, including the Entergy Corporation Retirement Plan for Non-Bargaining Employees (Non-Bargaining Plan I), the Entergy Corporation Retirement Plan for Bargaining Employees (Bargaining Plan I), the Entergy Corporation Retirement Plan II for Non-Bargaining Employees (Non-Bargaining Plan II), the Entergy Corporation Retirement Plan II for Bargaining Employees (Bargaining Plan II), the Entergy Corporation Retirement Plan III (Plan III), the Entergy Corporation Retirement Plan IV for Bargaining Employees, Entergy Corporation Retirement Plan VI for Non-Bargaining Employees (Non-Bargaining Plan VI), and the Entergy Corporation Cash Balance Plan for Bargaining Employees (Bargaining Cash Balance Plan). The Entergy Corporation Cash Balance Plan for Non-Bargaining Employees (Non-Bargaining Cash Balance Plan) was merged with and into Non-Bargaining Plan I effective January 1, 2022. Effective January 1, 2024, Non-Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Non-Bargaining Plan VI. Effective January 1, 2025, Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Entergy Corporation Plan VI for Bargaining Employees (Bargaining Plan VI). The Bargaining Cash Balance Plan was merged with and into Bargaining Plan I also effective January 1, 2025. The Registrant Subsidiaries participate in these plans: Non-Bargaining Plan I, Bargaining Plan I, Plan III, Non-Bargaining Plan VI, and Bargaining Cash Balance Plan. Non-bargaining and bargaining employees whose most recent date of hire was prior to June 30, 2014 (or such later date provided for in their applicable collective bargaining agreement) participate in a noncontributory final average pay formula that provides pension benefits based on the employee’s credited service and compensation during employment. Non-bargaining and bargaining employees whose most recent date of hire is after June 30, 2014 and before January 1, 2021 (or such later date provided for in their applicable collective bargaining agreement) do not participate in a final average pay formula, but instead participate in a cash balance formula. Effective January 1, 2021, the Non-Bargaining Cash Balance Plan and Bargaining Cash Balance Plan were amended to close participation in each plan to those employees whose most recent hire date is after December 31, 2020 (or such later date provided for in their applicable collective bargaining agreement). Employees hired after this date instead may be eligible to participate in and receive a discretionary employer contribution under an Entergy sponsored tax-qualified defined contribution plan that includes a 401(k) feature. The assets of the defined benefit qualified pension plans are held in a master trust established by Entergy. Each pension plan has an undivided beneficial interest in each of the investment accounts in the master trust that is maintained by a trustee. Use of the master trust permits the commingling of the trust assets of the pension plans of Entergy Corporation and its Registrant Subsidiaries for investment and administrative purposes. Although assets in the master trust are commingled, the trustee maintains supporting records for the purpose of allocating the trust level equity in net earnings (loss) and the administrative expenses of the investment accounts in the trust to the various participating pension plans in the trust. The fair value of the trust’s assets is determined by the trustee and certain investment managers. The trustee calculates a daily earnings factor, including realized and unrealized gains or losses, collected and accrued income, and administrative expenses, and allocates earnings to each plan in the master trust on a pro rata basis. Within each pension plan, the record of each Registrant Subsidiary’s beneficial interest in the plan assets is maintained by the plan’s actuary and is updated quarterly. Assets for each Registrant Subsidiary are increased for investment net income and contributions and are decreased for benefit payments. A plan’s investment net income/loss (i.e., interest and dividends, realized and unrealized gains and losses and expenses) is allocated to the Registrant Subsidiaries participating in that plan based on the value of assets for each Registrant Subsidiary at the beginning of the quarter adjusted for contributions and benefit payments made during the quarter. Entergy Corporation and its subsidiaries fund pension plans in an amount not less than the minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The assets of the plans include common and preferred stocks, fixed-income securities, interest in a money market fund, and insurance contracts. The Registrant Subsidiaries’ pension costs are recovered from customers as a component of cost of service in each of their respective jurisdictions. Components of Qualified Net Pension Cost and Other Amounts Recognized as a Regulatory Asset and/or Accumulated Other Comprehensive Income (AOCI) Entergy Corporation and its subsidiaries’ total 2024, 2023, and 2022 qualified pension costs and amounts recognized as a regulatory asset and/or other comprehensive income, including amounts capitalized, included the following components: 2024 2023 2022 (In Thousands) Net periodic pension cost: Service cost -

The qualified pension plans incurred net actuarial gains during 2024 primarily due to liability gains due to a rise in bond yields that resulted in increases to the discount rates used to develop the benefit obligations; partially offset by asset losses resulting from an actual return on assets lower than the expected return on assets in some plans. The qualified pension plans incurred net actuarial gains during 2023 primarily due to asset gains resulting from an actual return on assets much higher than the expected return on assets, offset by liability losses due to a decline in bond yields that resulted in decreases to the discount rates used to develop the benefit obligations. The accumulated benefit obligation for Entergy’s qualified pension plans was $4.1 billion and $5.6 billion at December 31, 2024 and 2023, respectively. Information for Entergy’s qualified pension plans with an accumulated benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Accumulated benefit obligation $912,174 $2,508,990 Fair value of plan assets $864,795 $2,300,937 Information for Entergy’s qualified pension plans with a projected benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Projected benefit obligation $2,701,323 $4,385,472 Fair value of plan assets $2,542,693 $3,898,434 The qualified pension accumulated benefit obligation for each of the Registrant Subsidiaries for their current and former employees as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Entergy Arkansas $980,559 $1,048,901 Entergy Louisiana $1,024,433 $1,085,318 Entergy Mississippi $257,759 $273,338 Entergy New Orleans $118,620 $125,878 Entergy Texas $212,935 $225,379 System Energy $252,397 $267,432 Information for each of the Registrant Subsidiaries qualified pension plans with an accumulated benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy Texas System Energy (In Thousands) Accumulated benefit obligation $304,518 $123,735 $105,285 $58,082 $44,286 Fair value of plan assets $297,161 $115,446 $103,380 $55,953 $40,146 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Accumulated benefit obligation $612,788 $658,373 $202,182 $125,878 $70,680 $127,606 Fair value of plan assets $554,362 $607,471 $196,500 $117,922 $61,495 $109,266 Information for each of the Registrant Subsidiaries qualified pension plans with a projected benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Projected benefit obligation $1,009,496 $580,451 $111,659 $108,354 $128,652 $247,186 Fair value of plan assets $962,101 $559,017 $103,380 $103,727 $120,700 $238,833 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Projected benefit obligation $1,117,586 $1,173,284 $213,098 $133,949 $146,511 $286,558 Fair value of plan assets $991,894 $1,058,711 $196,500 $117,922 $128,991 $255,443 Other Postretirement Benefits Entergy also currently offers retiree medical, dental, vision, and life insurance benefits (other postretirement benefits) for eligible retired employees. Employees who commenced employment before July 1, 2014 and who satisfy certain eligibility requirements (including retiring from Entergy after a certain age and/or years of service with Entergy and immediately commencing their Entergy pension benefit), may become eligible for other postretirement benefits. In March 2020, Entergy announced changes to its other postretirement benefits. Effective January 1, 2021, certain retired, former non-bargaining employees age 65 and older who are eligible for Entergy-sponsored retiree welfare benefits, and their eligible spouses who are age 65 and older (collectively, Medicare-eligible participants), are eligible to participate in an Entergy-sponsored retiree health plan, and are no longer eligible for retiree coverage under the Entergy Corporation Companies’ Benefits Plus Medical, Dental and Vision Plans. Under the Entergy-sponsored retiree health plan, Medicare-eligible participants are eligible to participate in a health reimbursement arrangement which they may use towards the purchase of various types of qualified insurance offered through a Medicare exchange provider and for other qualified medical expenses. The changes affecting active bargaining unit employees were negotiated with the unions prior to implementation, where necessary, and to the extent required by law. Effective January 1, 1993, Entergy adopted an accounting standard requiring a change from a cash method to an accrual method of accounting for postretirement benefits other than pensions. Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy have received regulatory approval to recover accrued other postretirement benefits costs through rates. The LPSC ordered Entergy Louisiana to continue the use of the pay-as-you-go method for ratemaking purposes for postretirement benefits other than pensions. However, the LPSC retains the flexibility to examine individual companies’ accounting for other postretirement benefits to determine if special exceptions to this order are warranted. Pursuant to regulatory directives, Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy contribute the other postretirement benefits costs collected in rates into external trusts. System Energy is funding, on behalf of Entergy Operations, other postretirement benefits associated with employees who work or worked at Grand Gulf. Trust assets contributed by participating Registrant Subsidiaries are in master trusts, established by Entergy Corporation and maintained by a trustee. Each plan has an undivided beneficial interest in each of the investment accounts in its respective master trust that is maintained by a trustee. Each participating Registrant Subsidiary holds a beneficial interest in the plans’ investment accounts. The assets in the master trusts are commingled for investment and administrative purposes. Although assets are commingled, supporting records are maintained for the purpose of allocating the beneficial interest in net earnings/(losses) and the administrative expenses of the investment accounts to the various participating plans and participating Registrant Subsidiaries. Beneficial interest in an investment account’s net income/(loss) is comprised of interest and dividends, realized and unrealized gains and losses, and expenses. Beneficial interest from these investments is allocated to the plans and participating Registrant Subsidiary based on their portion of net assets in the pooled accounts.

Retirement Benefits [Text Block]	RETIREMENT, OTHER POSTRETIREMENT BENEFITS, AND DEFINED CONTRIBUTION PLANS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Qualified Pension Plans Entergy has defined benefit qualified pension plans, including the Entergy Corporation Retirement Plan for Non-Bargaining Employees (Non-Bargaining Plan I), the Entergy Corporation Retirement Plan for Bargaining Employees (Bargaining Plan I), the Entergy Corporation Retirement Plan II for Non-Bargaining Employees (Non-Bargaining Plan II), the Entergy Corporation Retirement Plan II for Bargaining Employees (Bargaining Plan II), the Entergy Corporation Retirement Plan III (Plan III), the Entergy Corporation Retirement Plan IV for Bargaining Employees, Entergy Corporation Retirement Plan VI for Non-Bargaining Employees (Non-Bargaining Plan VI), and the Entergy Corporation Cash Balance Plan for Bargaining Employees (Bargaining Cash Balance Plan). The Entergy Corporation Cash Balance Plan for Non-Bargaining Employees (Non-Bargaining Cash Balance Plan) was merged with and into Non-Bargaining Plan I effective January 1, 2022. Effective January 1, 2024, Non-Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Non-Bargaining Plan VI. Effective January 1, 2025, Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Entergy Corporation Plan VI for Bargaining Employees (Bargaining Plan VI). The Bargaining Cash Balance Plan was merged with and into Bargaining Plan I also effective January 1, 2025. The Registrant Subsidiaries participate in these plans: Non-Bargaining Plan I, Bargaining Plan I, Plan III, Non-Bargaining Plan VI, and Bargaining Cash Balance Plan. Non-bargaining and bargaining employees whose most recent date of hire was prior to June 30, 2014 (or such later date provided for in their applicable collective bargaining agreement) participate in a noncontributory final average pay formula that provides pension benefits based on the employee’s credited service and compensation during employment. Non-bargaining and bargaining employees whose most recent date of hire is after June 30, 2014 and before January 1, 2021 (or such later date provided for in their applicable collective bargaining agreement) do not participate in a final average pay formula, but instead participate in a cash balance formula. Effective January 1, 2021, the Non-Bargaining Cash Balance Plan and Bargaining Cash Balance Plan were amended to close participation in each plan to those employees whose most recent hire date is after December 31, 2020 (or such later date provided for in their applicable collective bargaining agreement). Employees hired after this date instead may be eligible to participate in and receive a discretionary employer contribution under an Entergy sponsored tax-qualified defined contribution plan that includes a 401(k) feature. The assets of the defined benefit qualified pension plans are held in a master trust established by Entergy. Each pension plan has an undivided beneficial interest in each of the investment accounts in the master trust that is maintained by a trustee. Use of the master trust permits the commingling of the trust assets of the pension plans of Entergy Corporation and its Registrant Subsidiaries for investment and administrative purposes. Although assets in the master trust are commingled, the trustee maintains supporting records for the purpose of allocating the trust level equity in net earnings (loss) and the administrative expenses of the investment accounts in the trust to the various participating pension plans in the trust. The fair value of the trust’s assets is determined by the trustee and certain investment managers. The trustee calculates a daily earnings factor, including realized and unrealized gains or losses, collected and accrued income, and administrative expenses, and allocates earnings to each plan in the master trust on a pro rata basis. Within each pension plan, the record of each Registrant Subsidiary’s beneficial interest in the plan assets is maintained by the plan’s actuary and is updated quarterly. Assets for each Registrant Subsidiary are increased for investment net income and contributions and are decreased for benefit payments. A plan’s investment net income/loss (i.e., interest and dividends, realized and unrealized gains and losses and expenses) is allocated to the Registrant Subsidiaries participating in that plan based on the value of assets for each Registrant Subsidiary at the beginning of the quarter adjusted for contributions and benefit payments made during the quarter. Entergy Corporation and its subsidiaries fund pension plans in an amount not less than the minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The assets of the plans include common and preferred stocks, fixed-income securities, interest in a money market fund, and insurance contracts. The Registrant Subsidiaries’ pension costs are recovered from customers as a component of cost of service in each of their respective jurisdictions.

The qualified pension plans incurred net actuarial gains during 2024 primarily due to liability gains due to a rise in bond yields that resulted in increases to the discount rates used to develop the benefit obligations; partially offset by asset losses resulting from an actual return on assets lower than the expected return on assets in some plans. The qualified pension plans incurred net actuarial gains during 2023 primarily due to asset gains resulting from an actual return on assets much higher than the expected return on assets, offset by liability losses due to a decline in bond yields that resulted in decreases to the discount rates used to develop the benefit obligations. The accumulated benefit obligation for Entergy’s qualified pension plans was $4.1 billion and $5.6 billion at December 31, 2024 and 2023, respectively.

Employees who commenced employment before July 1, 2014 and who satisfy certain eligibility requirements (including retiring from Entergy after a certain age and/or years of service with Entergy and immediately commencing their Entergy pension benefit), may become eligible for other postretirement benefits. In March 2020, Entergy announced changes to its other postretirement benefits. Effective January 1, 2021, certain retired, former non-bargaining employees age 65 and older who are eligible for Entergy-sponsored retiree welfare benefits, and their eligible spouses who are age 65 and older (collectively, Medicare-eligible participants), are eligible to participate in an Entergy-sponsored retiree health plan, and are no longer eligible for retiree coverage under the Entergy Corporation Companies’ Benefits Plus Medical, Dental and Vision Plans. Under the Entergy-sponsored retiree health plan, Medicare-eligible participants are eligible to participate in a health reimbursement arrangement which they may use towards the purchase of various types of qualified insurance offered through a Medicare exchange provider and for other qualified medical expenses. The changes affecting active bargaining unit employees were negotiated with the unions prior to implementation, where necessary, and to the extent required by law. Effective January 1, 1993, Entergy adopted an accounting standard requiring a change from a cash method to an accrual method of accounting for postretirement benefits other than pensions. Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy have received regulatory approval to recover accrued other postretirement benefits costs through rates. The LPSC ordered Entergy Louisiana to continue the use of the pay-as-you-go method for ratemaking purposes for postretirement benefits other than pensions. However, the LPSC retains the flexibility to examine individual companies’ accounting for other postretirement benefits to determine if special exceptions to this order are warranted. Pursuant to regulatory directives, Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy contribute the other postretirement benefits costs collected in rates into external trusts. System Energy is funding, on behalf of Entergy Operations, other postretirement benefits associated with employees who work or worked at Grand Gulf. Trust assets contributed by participating Registrant Subsidiaries are in master trusts, established by Entergy Corporation and maintained by a trustee. Each plan has an undivided beneficial interest in each of the investment accounts in its respective master trust that is maintained by a trustee. Each participating Registrant Subsidiary holds a beneficial interest in the plans’ investment accounts. The assets in the master trusts are commingled for investment and administrative purposes. Although assets are commingled, supporting records are maintained for the purpose of allocating the beneficial interest in net earnings/(losses) and the administrative expenses of the investment accounts to the various participating plans and participating Registrant Subsidiaries. Beneficial interest in an investment account’s net income/(loss) is comprised of interest and dividends, realized and unrealized gains and losses, and expenses. Beneficial interest from these investments is allocated to the plans and participating Registrant Subsidiary based on their portion of net assets in the pooled accounts.

Retirement Benefits [Text Block]	RETIREMENT, OTHER POSTRETIREMENT BENEFITS, AND DEFINED CONTRIBUTION PLANS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Qualified Pension Plans Entergy has defined benefit qualified pension plans, including the Entergy Corporation Retirement Plan for Non-Bargaining Employees (Non-Bargaining Plan I), the Entergy Corporation Retirement Plan for Bargaining Employees (Bargaining Plan I), the Entergy Corporation Retirement Plan II for Non-Bargaining Employees (Non-Bargaining Plan II), the Entergy Corporation Retirement Plan II for Bargaining Employees (Bargaining Plan II), the Entergy Corporation Retirement Plan III (Plan III), the Entergy Corporation Retirement Plan IV for Bargaining Employees, Entergy Corporation Retirement Plan VI for Non-Bargaining Employees (Non-Bargaining Plan VI), and the Entergy Corporation Cash Balance Plan for Bargaining Employees (Bargaining Cash Balance Plan). The Entergy Corporation Cash Balance Plan for Non-Bargaining Employees (Non-Bargaining Cash Balance Plan) was merged with and into Non-Bargaining Plan I effective January 1, 2022. Effective January 1, 2024, Non-Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Non-Bargaining Plan VI. Effective January 1, 2025, Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Entergy Corporation Plan VI for Bargaining Employees (Bargaining Plan VI). The Bargaining Cash Balance Plan was merged with and into Bargaining Plan I also effective January 1, 2025. The Registrant Subsidiaries participate in these plans: Non-Bargaining Plan I, Bargaining Plan I, Plan III, Non-Bargaining Plan VI, and Bargaining Cash Balance Plan. Non-bargaining and bargaining employees whose most recent date of hire was prior to June 30, 2014 (or such later date provided for in their applicable collective bargaining agreement) participate in a noncontributory final average pay formula that provides pension benefits based on the employee’s credited service and compensation during employment. Non-bargaining and bargaining employees whose most recent date of hire is after June 30, 2014 and before January 1, 2021 (or such later date provided for in their applicable collective bargaining agreement) do not participate in a final average pay formula, but instead participate in a cash balance formula. Effective January 1, 2021, the Non-Bargaining Cash Balance Plan and Bargaining Cash Balance Plan were amended to close participation in each plan to those employees whose most recent hire date is after December 31, 2020 (or such later date provided for in their applicable collective bargaining agreement). Employees hired after this date instead may be eligible to participate in and receive a discretionary employer contribution under an Entergy sponsored tax-qualified defined contribution plan that includes a 401(k) feature. The assets of the defined benefit qualified pension plans are held in a master trust established by Entergy. Each pension plan has an undivided beneficial interest in each of the investment accounts in the master trust that is maintained by a trustee. Use of the master trust permits the commingling of the trust assets of the pension plans of Entergy Corporation and its Registrant Subsidiaries for investment and administrative purposes. Although assets in the master trust are commingled, the trustee maintains supporting records for the purpose of allocating the trust level equity in net earnings (loss) and the administrative expenses of the investment accounts in the trust to the various participating pension plans in the trust. The fair value of the trust’s assets is determined by the trustee and certain investment managers. The trustee calculates a daily earnings factor, including realized and unrealized gains or losses, collected and accrued income, and administrative expenses, and allocates earnings to each plan in the master trust on a pro rata basis. Within each pension plan, the record of each Registrant Subsidiary’s beneficial interest in the plan assets is maintained by the plan’s actuary and is updated quarterly. Assets for each Registrant Subsidiary are increased for investment net income and contributions and are decreased for benefit payments. A plan’s investment net income/loss (i.e., interest and dividends, realized and unrealized gains and losses and expenses) is allocated to the Registrant Subsidiaries participating in that plan based on the value of assets for each Registrant Subsidiary at the beginning of the quarter adjusted for contributions and benefit payments made during the quarter. Entergy Corporation and its subsidiaries fund pension plans in an amount not less than the minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The assets of the plans include common and preferred stocks, fixed-income securities, interest in a money market fund, and insurance contracts. The Registrant Subsidiaries’ pension costs are recovered from customers as a component of cost of service in each of their respective jurisdictions.

The qualified pension plans incurred net actuarial gains during 2024 primarily due to liability gains due to a rise in bond yields that resulted in increases to the discount rates used to develop the benefit obligations; partially offset by asset losses resulting from an actual return on assets lower than the expected return on assets in some plans. The qualified pension plans incurred net actuarial gains during 2023 primarily due to asset gains resulting from an actual return on assets much higher than the expected return on assets, offset by liability losses due to a decline in bond yields that resulted in decreases to the discount rates used to develop the benefit obligations. The accumulated benefit obligation for Entergy’s qualified pension plans was $4.1 billion and $5.6 billion at December 31, 2024 and 2023, respectively. Information for Entergy’s qualified pension plans with an accumulated benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Accumulated benefit obligation $912,174 $2,508,990 Fair value of plan assets $864,795 $2,300,937 Information for Entergy’s qualified pension plans with a projected benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Projected benefit obligation $2,701,323 $4,385,472 Fair value of plan assets $2,542,693 $3,898,434 The qualified pension accumulated benefit obligation for each of the Registrant Subsidiaries for their current and former employees as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Entergy Arkansas $980,559 $1,048,901 Entergy Louisiana $1,024,433 $1,085,318 Entergy Mississippi $257,759 $273,338 Entergy New Orleans $118,620 $125,878 Entergy Texas $212,935 $225,379 System Energy $252,397 $267,432 Information for each of the Registrant Subsidiaries qualified pension plans with an accumulated benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy Texas System Energy (In Thousands) Accumulated benefit obligation $304,518 $123,735 $105,285 $58,082 $44,286 Fair value of plan assets $297,161 $115,446 $103,380 $55,953 $40,146 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Accumulated benefit obligation $612,788 $658,373 $202,182 $125,878 $70,680 $127,606 Fair value of plan assets $554,362 $607,471 $196,500 $117,922 $61,495 $109,266 Information for each of the Registrant Subsidiaries qualified pension plans with a projected benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Projected benefit obligation $1,009,496 $580,451 $111,659 $108,354 $128,652 $247,186 Fair value of plan assets $962,101 $559,017 $103,380 $103,727 $120,700 $238,833 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Projected benefit obligation $1,117,586 $1,173,284 $213,098 $133,949 $146,511 $286,558 Fair value of plan assets $991,894 $1,058,711 $196,500 $117,922 $128,991 $255,443 Other Postretirement Benefits Entergy also currently offers retiree medical, dental, vision, and life insurance benefits (other postretirement benefits) for eligible retired employees. Employees who commenced employment before July 1, 2014 and who satisfy certain eligibility requirements (including retiring from Entergy after a certain age and/or years of service with Entergy and immediately commencing their Entergy pension benefit), may become eligible for other postretirement benefits. In March 2020, Entergy announced changes to its other postretirement benefits. Effective January 1, 2021, certain retired, former non-bargaining employees age 65 and older who are eligible for Entergy-sponsored retiree welfare benefits, and their eligible spouses who are age 65 and older (collectively, Medicare-eligible participants), are eligible to participate in an Entergy-sponsored retiree health plan, and are no longer eligible for retiree coverage under the Entergy Corporation Companies’ Benefits Plus Medical, Dental and Vision Plans. Under the Entergy-sponsored retiree health plan, Medicare-eligible participants are eligible to participate in a health reimbursement arrangement which they may use towards the purchase of various types of qualified insurance offered through a Medicare exchange provider and for other qualified medical expenses. The changes affecting active bargaining unit employees were negotiated with the unions prior to implementation, where necessary, and to the extent required by law. Effective January 1, 1993, Entergy adopted an accounting standard requiring a change from a cash method to an accrual method of accounting for postretirement benefits other than pensions. Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy have received regulatory approval to recover accrued other postretirement benefits costs through rates. The LPSC ordered Entergy Louisiana to continue the use of the pay-as-you-go method for ratemaking purposes for postretirement benefits other than pensions. However, the LPSC retains the flexibility to examine individual companies’ accounting for other postretirement benefits to determine if special exceptions to this order are warranted. Pursuant to regulatory directives, Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy contribute the other postretirement benefits costs collected in rates into external trusts. System Energy is funding, on behalf of Entergy Operations, other postretirement benefits associated with employees who work or worked at Grand Gulf. Trust assets contributed by participating Registrant Subsidiaries are in master trusts, established by Entergy Corporation and maintained by a trustee. Each plan has an undivided beneficial interest in each of the investment accounts in its respective master trust that is maintained by a trustee. Each participating Registrant Subsidiary holds a beneficial interest in the plans’ investment accounts. The assets in the master trusts are commingled for investment and administrative purposes. Although assets are commingled, supporting records are maintained for the purpose of allocating the beneficial interest in net earnings/(losses) and the administrative expenses of the investment accounts to the various participating plans and participating Registrant Subsidiaries. Beneficial interest in an investment account’s net income/(loss) is comprised of interest and dividends, realized and unrealized gains and losses, and expenses. Beneficial interest from these investments is allocated to the plans and participating Registrant Subsidiary based on their portion of net assets in the pooled accounts.

Retirement Benefits [Text Block]	RETIREMENT, OTHER POSTRETIREMENT BENEFITS, AND DEFINED CONTRIBUTION PLANS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Qualified Pension Plans Entergy has defined benefit qualified pension plans, including the Entergy Corporation Retirement Plan for Non-Bargaining Employees (Non-Bargaining Plan I), the Entergy Corporation Retirement Plan for Bargaining Employees (Bargaining Plan I), the Entergy Corporation Retirement Plan II for Non-Bargaining Employees (Non-Bargaining Plan II), the Entergy Corporation Retirement Plan II for Bargaining Employees (Bargaining Plan II), the Entergy Corporation Retirement Plan III (Plan III), the Entergy Corporation Retirement Plan IV for Bargaining Employees, Entergy Corporation Retirement Plan VI for Non-Bargaining Employees (Non-Bargaining Plan VI), and the Entergy Corporation Cash Balance Plan for Bargaining Employees (Bargaining Cash Balance Plan). The Entergy Corporation Cash Balance Plan for Non-Bargaining Employees (Non-Bargaining Cash Balance Plan) was merged with and into Non-Bargaining Plan I effective January 1, 2022. Effective January 1, 2024, Non-Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Non-Bargaining Plan VI. Effective January 1, 2025, Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Entergy Corporation Plan VI for Bargaining Employees (Bargaining Plan VI). The Bargaining Cash Balance Plan was merged with and into Bargaining Plan I also effective January 1, 2025. The Registrant Subsidiaries participate in these plans: Non-Bargaining Plan I, Bargaining Plan I, Plan III, Non-Bargaining Plan VI, and Bargaining Cash Balance Plan. Non-bargaining and bargaining employees whose most recent date of hire was prior to June 30, 2014 (or such later date provided for in their applicable collective bargaining agreement) participate in a noncontributory final average pay formula that provides pension benefits based on the employee’s credited service and compensation during employment. Non-bargaining and bargaining employees whose most recent date of hire is after June 30, 2014 and before January 1, 2021 (or such later date provided for in their applicable collective bargaining agreement) do not participate in a final average pay formula, but instead participate in a cash balance formula. Effective January 1, 2021, the Non-Bargaining Cash Balance Plan and Bargaining Cash Balance Plan were amended to close participation in each plan to those employees whose most recent hire date is after December 31, 2020 (or such later date provided for in their applicable collective bargaining agreement). Employees hired after this date instead may be eligible to participate in and receive a discretionary employer contribution under an Entergy sponsored tax-qualified defined contribution plan that includes a 401(k) feature. The assets of the defined benefit qualified pension plans are held in a master trust established by Entergy. Each pension plan has an undivided beneficial interest in each of the investment accounts in the master trust that is maintained by a trustee. Use of the master trust permits the commingling of the trust assets of the pension plans of Entergy Corporation and its Registrant Subsidiaries for investment and administrative purposes. Although assets in the master trust are commingled, the trustee maintains supporting records for the purpose of allocating the trust level equity in net earnings (loss) and the administrative expenses of the investment accounts in the trust to the various participating pension plans in the trust. The fair value of the trust’s assets is determined by the trustee and certain investment managers. The trustee calculates a daily earnings factor, including realized and unrealized gains or losses, collected and accrued income, and administrative expenses, and allocates earnings to each plan in the master trust on a pro rata basis. Within each pension plan, the record of each Registrant Subsidiary’s beneficial interest in the plan assets is maintained by the plan’s actuary and is updated quarterly. Assets for each Registrant Subsidiary are increased for investment net income and contributions and are decreased for benefit payments. A plan’s investment net income/loss (i.e., interest and dividends, realized and unrealized gains and losses and expenses) is allocated to the Registrant Subsidiaries participating in that plan based on the value of assets for each Registrant Subsidiary at the beginning of the quarter adjusted for contributions and benefit payments made during the quarter. Entergy Corporation and its subsidiaries fund pension plans in an amount not less than the minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The assets of the plans include common and preferred stocks, fixed-income securities, interest in a money market fund, and insurance contracts. The Registrant Subsidiaries’ pension costs are recovered from customers as a component of cost of service in each of their respective jurisdictions.

The qualified pension plans incurred net actuarial gains during 2024 primarily due to liability gains due to a rise in bond yields that resulted in increases to the discount rates used to develop the benefit obligations; partially offset by asset losses resulting from an actual return on assets lower than the expected return on assets in some plans. The qualified pension plans incurred net actuarial gains during 2023 primarily due to asset gains resulting from an actual return on assets much higher than the expected return on assets, offset by liability losses due to a decline in bond yields that resulted in decreases to the discount rates used to develop the benefit obligations. The accumulated benefit obligation for Entergy’s qualified pension plans was $4.1 billion and $5.6 billion at December 31, 2024 and 2023, respectively.

Employees who commenced employment before July 1, 2014 and who satisfy certain eligibility requirements (including retiring from Entergy after a certain age and/or years of service with Entergy and immediately commencing their Entergy pension benefit), may become eligible for other postretirement benefits. In March 2020, Entergy announced changes to its other postretirement benefits. Effective January 1, 2021, certain retired, former non-bargaining employees age 65 and older who are eligible for Entergy-sponsored retiree welfare benefits, and their eligible spouses who are age 65 and older (collectively, Medicare-eligible participants), are eligible to participate in an Entergy-sponsored retiree health plan, and are no longer eligible for retiree coverage under the Entergy Corporation Companies’ Benefits Plus Medical, Dental and Vision Plans. Under the Entergy-sponsored retiree health plan, Medicare-eligible participants are eligible to participate in a health reimbursement arrangement which they may use towards the purchase of various types of qualified insurance offered through a Medicare exchange provider and for other qualified medical expenses. The changes affecting active bargaining unit employees were negotiated with the unions prior to implementation, where necessary, and to the extent required by law. Effective January 1, 1993, Entergy adopted an accounting standard requiring a change from a cash method to an accrual method of accounting for postretirement benefits other than pensions. Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy have received regulatory approval to recover accrued other postretirement benefits costs through rates. The LPSC ordered Entergy Louisiana to continue the use of the pay-as-you-go method for ratemaking purposes for postretirement benefits other than pensions. However, the LPSC retains the flexibility to examine individual companies’ accounting for other postretirement benefits to determine if special exceptions to this order are warranted. Pursuant to regulatory directives, Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy contribute the other postretirement benefits costs collected in rates into external trusts. System Energy is funding, on behalf of Entergy Operations, other postretirement benefits associated with employees who work or worked at Grand Gulf. Trust assets contributed by participating Registrant Subsidiaries are in master trusts, established by Entergy Corporation and maintained by a trustee. Each plan has an undivided beneficial interest in each of the investment accounts in its respective master trust that is maintained by a trustee. Each participating Registrant Subsidiary holds a beneficial interest in the plans’ investment accounts. The assets in the master trusts are commingled for investment and administrative purposes. Although assets are commingled, supporting records are maintained for the purpose of allocating the beneficial interest in net earnings/(losses) and the administrative expenses of the investment accounts to the various participating plans and participating Registrant Subsidiaries. Beneficial interest in an investment account’s net income/(loss) is comprised of interest and dividends, realized and unrealized gains and losses, and expenses. Beneficial interest from these investments is allocated to the plans and participating Registrant Subsidiary based on their portion of net assets in the pooled accounts.

Retirement Benefits [Text Block]	RETIREMENT, OTHER POSTRETIREMENT BENEFITS, AND DEFINED CONTRIBUTION PLANS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Qualified Pension Plans Entergy has defined benefit qualified pension plans, including the Entergy Corporation Retirement Plan for Non-Bargaining Employees (Non-Bargaining Plan I), the Entergy Corporation Retirement Plan for Bargaining Employees (Bargaining Plan I), the Entergy Corporation Retirement Plan II for Non-Bargaining Employees (Non-Bargaining Plan II), the Entergy Corporation Retirement Plan II for Bargaining Employees (Bargaining Plan II), the Entergy Corporation Retirement Plan III (Plan III), the Entergy Corporation Retirement Plan IV for Bargaining Employees, Entergy Corporation Retirement Plan VI for Non-Bargaining Employees (Non-Bargaining Plan VI), and the Entergy Corporation Cash Balance Plan for Bargaining Employees (Bargaining Cash Balance Plan). The Entergy Corporation Cash Balance Plan for Non-Bargaining Employees (Non-Bargaining Cash Balance Plan) was merged with and into Non-Bargaining Plan I effective January 1, 2022. Effective January 1, 2024, Non-Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Non-Bargaining Plan VI. Effective January 1, 2025, Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Entergy Corporation Plan VI for Bargaining Employees (Bargaining Plan VI). The Bargaining Cash Balance Plan was merged with and into Bargaining Plan I also effective January 1, 2025. The Registrant Subsidiaries participate in these plans: Non-Bargaining Plan I, Bargaining Plan I, Plan III, Non-Bargaining Plan VI, and Bargaining Cash Balance Plan. Non-bargaining and bargaining employees whose most recent date of hire was prior to June 30, 2014 (or such later date provided for in their applicable collective bargaining agreement) participate in a noncontributory final average pay formula that provides pension benefits based on the employee’s credited service and compensation during employment. Non-bargaining and bargaining employees whose most recent date of hire is after June 30, 2014 and before January 1, 2021 (or such later date provided for in their applicable collective bargaining agreement) do not participate in a final average pay formula, but instead participate in a cash balance formula. Effective January 1, 2021, the Non-Bargaining Cash Balance Plan and Bargaining Cash Balance Plan were amended to close participation in each plan to those employees whose most recent hire date is after December 31, 2020 (or such later date provided for in their applicable collective bargaining agreement). Employees hired after this date instead may be eligible to participate in and receive a discretionary employer contribution under an Entergy sponsored tax-qualified defined contribution plan that includes a 401(k) feature. The assets of the defined benefit qualified pension plans are held in a master trust established by Entergy. Each pension plan has an undivided beneficial interest in each of the investment accounts in the master trust that is maintained by a trustee. Use of the master trust permits the commingling of the trust assets of the pension plans of Entergy Corporation and its Registrant Subsidiaries for investment and administrative purposes. Although assets in the master trust are commingled, the trustee maintains supporting records for the purpose of allocating the trust level equity in net earnings (loss) and the administrative expenses of the investment accounts in the trust to the various participating pension plans in the trust. The fair value of the trust’s assets is determined by the trustee and certain investment managers. The trustee calculates a daily earnings factor, including realized and unrealized gains or losses, collected and accrued income, and administrative expenses, and allocates earnings to each plan in the master trust on a pro rata basis. Within each pension plan, the record of each Registrant Subsidiary’s beneficial interest in the plan assets is maintained by the plan’s actuary and is updated quarterly. Assets for each Registrant Subsidiary are increased for investment net income and contributions and are decreased for benefit payments. A plan’s investment net income/loss (i.e., interest and dividends, realized and unrealized gains and losses and expenses) is allocated to the Registrant Subsidiaries participating in that plan based on the value of assets for each Registrant Subsidiary at the beginning of the quarter adjusted for contributions and benefit payments made during the quarter. Entergy Corporation and its subsidiaries fund pension plans in an amount not less than the minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The assets of the plans include common and preferred stocks, fixed-income securities, interest in a money market fund, and insurance contracts. The Registrant Subsidiaries’ pension costs are recovered from customers as a component of cost of service in each of their respective jurisdictions.

The qualified pension plans incurred net actuarial gains during 2024 primarily due to liability gains due to a rise in bond yields that resulted in increases to the discount rates used to develop the benefit obligations; partially offset by asset losses resulting from an actual return on assets lower than the expected return on assets in some plans. The qualified pension plans incurred net actuarial gains during 2023 primarily due to asset gains resulting from an actual return on assets much higher than the expected return on assets, offset by liability losses due to a decline in bond yields that resulted in decreases to the discount rates used to develop the benefit obligations. The accumulated benefit obligation for Entergy’s qualified pension plans was $4.1 billion and $5.6 billion at December 31, 2024 and 2023, respectively. Information for Entergy’s qualified pension plans with an accumulated benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Accumulated benefit obligation $912,174 $2,508,990 Fair value of plan assets $864,795 $2,300,937 Information for Entergy’s qualified pension plans with a projected benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Projected benefit obligation $2,701,323 $4,385,472 Fair value of plan assets $2,542,693 $3,898,434 The qualified pension accumulated benefit obligation for each of the Registrant Subsidiaries for their current and former employees as of December 31, 2024 and 2023 was as follows: 2024 2023 (In Thousands) Entergy Arkansas $980,559 $1,048,901 Entergy Louisiana $1,024,433 $1,085,318 Entergy Mississippi $257,759 $273,338 Entergy New Orleans $118,620 $125,878 Entergy Texas $212,935 $225,379 System Energy $252,397 $267,432 Information for each of the Registrant Subsidiaries qualified pension plans with an accumulated benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy Texas System Energy (In Thousands) Accumulated benefit obligation $304,518 $123,735 $105,285 $58,082 $44,286 Fair value of plan assets $297,161 $115,446 $103,380 $55,953 $40,146 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Accumulated benefit obligation $612,788 $658,373 $202,182 $125,878 $70,680 $127,606 Fair value of plan assets $554,362 $607,471 $196,500 $117,922 $61,495 $109,266 Information for each of the Registrant Subsidiaries qualified pension plans with a projected benefit obligation in excess of plan assets as of December 31, 2024 and 2023 was as follows: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Projected benefit obligation $1,009,496 $580,451 $111,659 $108,354 $128,652 $247,186 Fair value of plan assets $962,101 $559,017 $103,380 $103,727 $120,700 $238,833 2023 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Thousands) Projected benefit obligation $1,117,586 $1,173,284 $213,098 $133,949 $146,511 $286,558 Fair value of plan assets $991,894 $1,058,711 $196,500 $117,922 $128,991 $255,443 Other Postretirement Benefits Entergy also currently offers retiree medical, dental, vision, and life insurance benefits (other postretirement benefits) for eligible retired employees. Employees who commenced employment before July 1, 2014 and who satisfy certain eligibility requirements (including retiring from Entergy after a certain age and/or years of service with Entergy and immediately commencing their Entergy pension benefit), may become eligible for other postretirement benefits. In March 2020, Entergy announced changes to its other postretirement benefits. Effective January 1, 2021, certain retired, former non-bargaining employees age 65 and older who are eligible for Entergy-sponsored retiree welfare benefits, and their eligible spouses who are age 65 and older (collectively, Medicare-eligible participants), are eligible to participate in an Entergy-sponsored retiree health plan, and are no longer eligible for retiree coverage under the Entergy Corporation Companies’ Benefits Plus Medical, Dental and Vision Plans. Under the Entergy-sponsored retiree health plan, Medicare-eligible participants are eligible to participate in a health reimbursement arrangement which they may use towards the purchase of various types of qualified insurance offered through a Medicare exchange provider and for other qualified medical expenses. The changes affecting active bargaining unit employees were negotiated with the unions prior to implementation, where necessary, and to the extent required by law. Effective January 1, 1993, Entergy adopted an accounting standard requiring a change from a cash method to an accrual method of accounting for postretirement benefits other than pensions. Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy have received regulatory approval to recover accrued other postretirement benefits costs through rates. The LPSC ordered Entergy Louisiana to continue the use of the pay-as-you-go method for ratemaking purposes for postretirement benefits other than pensions. However, the LPSC retains the flexibility to examine individual companies’ accounting for other postretirement benefits to determine if special exceptions to this order are warranted. Pursuant to regulatory directives, Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy contribute the other postretirement benefits costs collected in rates into external trusts. System Energy is funding, on behalf of Entergy Operations, other postretirement benefits associated with employees who work or worked at Grand Gulf. Trust assets contributed by participating Registrant Subsidiaries are in master trusts, established by Entergy Corporation and maintained by a trustee. Each plan has an undivided beneficial interest in each of the investment accounts in its respective master trust that is maintained by a trustee. Each participating Registrant Subsidiary holds a beneficial interest in the plans’ investment accounts. The assets in the master trusts are commingled for investment and administrative purposes. Although assets are commingled, supporting records are maintained for the purpose of allocating the beneficial interest in net earnings/(losses) and the administrative expenses of the investment accounts to the various participating plans and participating Registrant Subsidiaries. Beneficial interest in an investment account’s net income/(loss) is comprised of interest and dividends, realized and unrealized gains and losses, and expenses. Beneficial interest from these investments is allocated to the plans and participating Registrant Subsidiary based on their portion of net assets in the pooled accounts.

Retirement Benefits [Text Block]	RETIREMENT, OTHER POSTRETIREMENT BENEFITS, AND DEFINED CONTRIBUTION PLANS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Qualified Pension Plans Entergy has defined benefit qualified pension plans, including the Entergy Corporation Retirement Plan for Non-Bargaining Employees (Non-Bargaining Plan I), the Entergy Corporation Retirement Plan for Bargaining Employees (Bargaining Plan I), the Entergy Corporation Retirement Plan II for Non-Bargaining Employees (Non-Bargaining Plan II), the Entergy Corporation Retirement Plan II for Bargaining Employees (Bargaining Plan II), the Entergy Corporation Retirement Plan III (Plan III), the Entergy Corporation Retirement Plan IV for Bargaining Employees, Entergy Corporation Retirement Plan VI for Non-Bargaining Employees (Non-Bargaining Plan VI), and the Entergy Corporation Cash Balance Plan for Bargaining Employees (Bargaining Cash Balance Plan). The Entergy Corporation Cash Balance Plan for Non-Bargaining Employees (Non-Bargaining Cash Balance Plan) was merged with and into Non-Bargaining Plan I effective January 1, 2022. Effective January 1, 2024, Non-Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Non-Bargaining Plan VI. Effective January 1, 2025, Bargaining Plan I was amended to spin-off predominately inactive participants into a new qualified pension plan, Entergy Corporation Plan VI for Bargaining Employees (Bargaining Plan VI). The Bargaining Cash Balance Plan was merged with and into Bargaining Plan I also effective January 1, 2025. The Registrant Subsidiaries participate in these plans: Non-Bargaining Plan I, Bargaining Plan I, Plan III, Non-Bargaining Plan VI, and Bargaining Cash Balance Plan. Non-bargaining and bargaining employees whose most recent date of hire was prior to June 30, 2014 (or such later date provided for in their applicable collective bargaining agreement) participate in a noncontributory final average pay formula that provides pension benefits based on the employee’s credited service and compensation during employment. Non-bargaining and bargaining employees whose most recent date of hire is after June 30, 2014 and before January 1, 2021 (or such later date provided for in their applicable collective bargaining agreement) do not participate in a final average pay formula, but instead participate in a cash balance formula. Effective January 1, 2021, the Non-Bargaining Cash Balance Plan and Bargaining Cash Balance Plan were amended to close participation in each plan to those employees whose most recent hire date is after December 31, 2020 (or such later date provided for in their applicable collective bargaining agreement). Employees hired after this date instead may be eligible to participate in and receive a discretionary employer contribution under an Entergy sponsored tax-qualified defined contribution plan that includes a 401(k) feature. The assets of the defined benefit qualified pension plans are held in a master trust established by Entergy. Each pension plan has an undivided beneficial interest in each of the investment accounts in the master trust that is maintained by a trustee. Use of the master trust permits the commingling of the trust assets of the pension plans of Entergy Corporation and its Registrant Subsidiaries for investment and administrative purposes. Although assets in the master trust are commingled, the trustee maintains supporting records for the purpose of allocating the trust level equity in net earnings (loss) and the administrative expenses of the investment accounts in the trust to the various participating pension plans in the trust. The fair value of the trust’s assets is determined by the trustee and certain investment managers. The trustee calculates a daily earnings factor, including realized and unrealized gains or losses, collected and accrued income, and administrative expenses, and allocates earnings to each plan in the master trust on a pro rata basis. Within each pension plan, the record of each Registrant Subsidiary’s beneficial interest in the plan assets is maintained by the plan’s actuary and is updated quarterly. Assets for each Registrant Subsidiary are increased for investment net income and contributions and are decreased for benefit payments. A plan’s investment net income/loss (i.e., interest and dividends, realized and unrealized gains and losses and expenses) is allocated to the Registrant Subsidiaries participating in that plan based on the value of assets for each Registrant Subsidiary at the beginning of the quarter adjusted for contributions and benefit payments made during the quarter. Entergy Corporation and its subsidiaries fund pension plans in an amount not less than the minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The assets of the plans include common and preferred stocks, fixed-income securities, interest in a money market fund, and insurance contracts. The Registrant Subsidiaries’ pension costs are recovered from customers as a component of cost of service in each of their respective jurisdictions.

The qualified pension plans incurred net actuarial gains during 2024 primarily due to liability gains due to a rise in bond yields that resulted in increases to the discount rates used to develop the benefit obligations; partially offset by asset losses resulting from an actual return on assets lower than the expected return on assets in some plans. The qualified pension plans incurred net actuarial gains during 2023 primarily due to asset gains resulting from an actual return on assets much higher than the expected return on assets, offset by liability losses due to a decline in bond yields that resulted in decreases to the discount rates used to develop the benefit obligations. The accumulated benefit obligation for Entergy’s qualified pension plans was $4.1 billion and $5.6 billion at December 31, 2024 and 2023, respectively.

Employees who commenced employment before July 1, 2014 and who satisfy certain eligibility requirements (including retiring from Entergy after a certain age and/or years of service with Entergy and immediately commencing their Entergy pension benefit), may become eligible for other postretirement benefits. In March 2020, Entergy announced changes to its other postretirement benefits. Effective January 1, 2021, certain retired, former non-bargaining employees age 65 and older who are eligible for Entergy-sponsored retiree welfare benefits, and their eligible spouses who are age 65 and older (collectively, Medicare-eligible participants), are eligible to participate in an Entergy-sponsored retiree health plan, and are no longer eligible for retiree coverage under the Entergy Corporation Companies’ Benefits Plus Medical, Dental and Vision Plans. Under the Entergy-sponsored retiree health plan, Medicare-eligible participants are eligible to participate in a health reimbursement arrangement which they may use towards the purchase of various types of qualified insurance offered through a Medicare exchange provider and for other qualified medical expenses. The changes affecting active bargaining unit employees were negotiated with the unions prior to implementation, where necessary, and to the extent required by law. Effective January 1, 1993, Entergy adopted an accounting standard requiring a change from a cash method to an accrual method of accounting for postretirement benefits other than pensions. Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy have received regulatory approval to recover accrued other postretirement benefits costs through rates. The LPSC ordered Entergy Louisiana to continue the use of the pay-as-you-go method for ratemaking purposes for postretirement benefits other than pensions. However, the LPSC retains the flexibility to examine individual companies’ accounting for other postretirement benefits to determine if special exceptions to this order are warranted. Pursuant to regulatory directives, Entergy Arkansas, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy contribute the other postretirement benefits costs collected in rates into external trusts. System Energy is funding, on behalf of Entergy Operations, other postretirement benefits associated with employees who work or worked at Grand Gulf. Trust assets contributed by participating Registrant Subsidiaries are in master trusts, established by Entergy Corporation and maintained by a trustee. Each plan has an undivided beneficial interest in each of the investment accounts in its respective master trust that is maintained by a trustee. Each participating Registrant Subsidiary holds a beneficial interest in the plans’ investment accounts. The assets in the master trusts are commingled for investment and administrative purposes. Although assets are commingled, supporting records are maintained for the purpose of allocating the beneficial interest in net earnings/(losses) and the administrative expenses of the investment accounts to the various participating plans and participating Registrant Subsidiaries. Beneficial interest in an investment account’s net income/(loss) is comprised of interest and dividends, realized and unrealized gains and losses, and expenses. Beneficial interest from these investments is allocated to the plans and participating Registrant Subsidiary based on their portion of net assets in the pooled accounts.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended
	Dec. 31, 2024
Share-Based Payment Arrangement [Text Block]	STOCK-BASED COMPENSATION (Entergy Corporation) Entergy grants stock options, restricted stock, performance units, and restricted stock units to key employees of the Entergy subsidiaries under its equity plans which are shareholder-approved stock-based compensation plans. The cost of the stock-based compensation is charged to income over the vesting period. Awards under Entergy’s plans generally vest over three years. Entergy accounts for forfeitures of stock-based compensation when they occur. Entergy recognizes all income tax effects related to share-based payments through the income statement. Historical share and share-based data presented herein for share-based compensation has been retroactively adjusted to reflect the two-for-one forward stock split of Entergy Corporation common stock effective December 12, 2024. See Note 7 to the financial statements for discussion of the stock split. Effective May 3, 2019, Entergy’s shareholders approved the 2019 Omnibus Incentive Plan (2019 Plan). The maximum number of common shares that can be issued from the 2019 Plan for stock-based awards is 24,400,000 all of which are available for incentive stock option grants. The 2019 Plan applies to awards granted on or after May 3, 2019 and awards expire ten years from the date of grant. As of December 31, 2024, there were 13,966,025 authorized shares remaining for stock-based awards. Stock Options Stock options are granted at exercise prices that equal the closing market price of Entergy Corporation common stock on the date of grant. Generally, stock options granted will become exercisable in equal amounts on each of the first three anniversaries of the date of grant. Unless they are forfeited previously under the terms of the grant, options expire 10 years after the date of the grant if they are not exercised. The following table includes financial information for stock options for each of the years presented: 2024 2023 2022 (In Millions) Compensation expense included in Entergy’s consolidated net income $4.0 $4.1 $4.2 Tax benefit recognized in Entergy’s consolidated net income $1.0 $1.1 $1.1 Compensation cost capitalized as part of fixed assets and materials and supplies $1.9 $1.9 $1.7 Entergy determines the fair value of the stock option grants by considering factors such as lack of marketability, stock retention requirements, and regulatory restrictions on exercisability in accordance with accounting standards. The stock option weighted-average assumptions used in determining the fair values are as follows: 2024 2023 2022 Stock price volatility 25.24% 24.89% 24.27% Expected term in years 6.88 6.89 6.92 Risk-free interest rate 4.03% 3.51% 1.77% Dividend yield 4.30% 4.00% 4.00% Dividend payment per share $2.30 $2.17 $2.05 Stock price volatility is calculated based upon the daily public stock price volatility of Entergy Corporation common stock over a period equal to the expected term of the award. The expected term of the options is based upon historical option exercises and the weighted-average life of options when exercised and the estimated weighted-average life of all vested but unexercised options. In 2008, Entergy implemented stock ownership guidelines for its senior executive officers. These guidelines require an executive officer to own shares of Entergy Corporation common stock equal to a specified multiple of his or her salary. Until an executive officer achieves this ownership position the executive officer is required to retain 75% of the net-of-tax net profit upon exercise of the option to be held in Entergy Corporation common stock. The reduction in fair value of the stock options due to this restriction is based upon an estimate of the call option value of the reinvested gain discounted to present value over the applicable reinvestment period. A summary of stock option activity for the year ended December 31, 2024 and changes during the year are presented below: Number of Options Weighted- Aggregate Intrinsic Value Weighted- (Dollars In Thousands, Except Per Share Data) Options outstanding as of January 1, 2024 5,797,416 $48.83 Options granted 704,398 $49.54 Options exercised (3,114,546) $43.83 Options forfeited/expired (160,812) $57.69 Options outstanding as of December 31, 2024 3,226,456 $53.38 $72,410 6.62 Options exercisable as of December 31, 2024 1,935,970 $54.38 $41,515 5.44 Weighted-average grant-date fair value of options granted during 2024 $9.31 The weighted-average grant-date fair value of options granted during the year was $10.04 for 2023 and $8.13 for 2022. The total intrinsic value of stock options exercised was $56 million during 2024, $2 million during 2023, and $20 million during 2022. The intrinsic value, which has no effect on net income, of the outstanding stock options exercised is calculated by the positive difference between the weighted-average exercise price of the stock options granted and Entergy Corporation’s common stock price as of December 31, 2024. Entergy recognizes compensation cost over the vesting period of the options based on their grant-date fair value. The total fair value of options that vested was approximately $6 million during 2024, $6 million during 2023, and $5 million during 2022. Cash received from option exercises was $136 million for the year ended December 31, 2024. The tax benefits realized from options exercised was $13.9 million for the year ended December 31, 2024.

Restricted Stock Awards Entergy grants restricted stock awards earned under its stock benefit plans in the form of stock units. One-third of the restricted stock awards and accrued dividends will vest upon each anniversary of the grant date and are expensed ratably over the three-year vesting period. Shares of restricted stock have the same dividend and voting rights as other common stock and are considered issued and outstanding shares of Entergy upon vesting. Restricted stock awards are valued at the closing price of Entergy Corporation’s common stock on the grant date. The following table includes information about the restricted stock awards outstanding as of December 31, 2024: Shares Weighted-Average Grant Date Fair Value Per Share Outstanding shares at January 1, 2024 1,253,547 $53.64 Granted 874,190 $49.68 Vested (605,320) $52.60 Forfeited (75,166) $52.47 Outstanding shares at December 31, 2024 1,447,251 $51.74 The following table includes financial information for restricted stock for each of the years presented: 2024 2023 2022 (In Millions) Compensation expense included in Entergy’s consolidated net income $24.4 $22.2 $23.2 Tax benefit recognized in Entergy’s consolidated net income $6.2 $5.7 $5.9 Compensation cost capitalized as part of fixed assets and materials and supplies $11.3 $9.7 $9.2 The total fair value of the restricted stock awards granted was $43 million, $41 million, and $39 million for the years ended December 31, 2024, 2023, and 2022, respectively. The total fair value of the restricted stock awards vested was $32 million, $33 million, and $34 million for the years ended December 31, 2024, 2023, and 2022, respectively. Long-Term Performance Unit Program Entergy grants long-term incentive awards earned under its stock benefit plans in the form of performance units, which represents the value of, and are settled with, one share of Entergy Corporation common stock at the end of the three-year performance period, plus dividends accrued during the performance period on the number of performance units earned. The Long-Term Performance Unit Program specifies a minimum, target, and maximum achievement level, the achievement of which will determine the number of performance units that may be earned. Entergy measures performance by assessing Entergy’s total shareholder return relative to the total shareholder return of the companies in the Philadelphia Utility Index. To emphasize the importance of environmental stewardship, specifically of carbon-free generation and resilience, an environmental achievement measure was selected as one of the performance measures for the 2024-2026 performance period. For the 2024-2026 performance period, performance will be measured based eighty percent on relative total shareholder return and twenty percent on the environmental achievement measure. The total shareholder return portion is valued based on various factors, primarily market conditions; and the environmental achievement measure portion is valued based on the closing price of Entergy Corporation’s common stock on the grant date. Performance units have the same dividend and voting rights as other common stock, are considered issued and outstanding shares of Entergy upon vesting, and are expensed ratably over the three-year vesting period, and compensation cost for the portion of the award based on the selected credit measure will be adjusted based on the number of units that ultimately vest.

Segment Reporting

Segment Reporting	12 Months Ended
	Dec. 31, 2024
Segment Reporting Disclosure [Text Block]	BUSINESS SEGMENT INFORMATION (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy has a single reportable segment, Utility, which includes the generation, transmission, distribution, and sale of electric power in portions of Arkansas, Mississippi, Texas, and Louisiana, including the City of New Orleans; and operation of a small natural gas distribution business in portions of Louisiana. Revenue for the Utility segment is primarily derived from retail electric sales. The accounting policies of the Utility segment are the same as those described in Note 1 to the financial statements. The Utility segment reflects management’s primary basis of organization with a predominant focus on its utility operations in the Gulf South. Entergy’s chief operating decision maker is its chief executive officer. The chief operating decision maker uses Utility net income in the annual planning process and to monitor budget versus actual results on a monthly basis in assessing financial performance and in determining how to allocate resources. Parent & Other includes the parent company, Entergy Corporation, and other business activity, including Entergy’s non-utility operations business, which is an operating segment that does not meet the quantitative thresholds for determining reportable segments. Entergy’s non-utility operations business owns interests in non-nuclear power plants that sell the electric power produced by those plants to wholesale customers and also provides decommissioning services to nuclear power plants owned by non-affiliated entities in the United States. The following table includes operating revenues and significant expense categories regularly provided to the chief operating decision maker for the Utility segment, a reconciliation of Utility operating revenues to Entergy’s consolidated operating revenues, and a reconciliation of Utility net income to consolidated net income and net income attributable to Entergy Corporation for each of the years presented: 2024 2023 2022 (In Thousands) Utility operating revenues $11,805,802 $12,022,944 $13,420,804 Reconciliation of revenues: Other revenues (a) 73,914 124,509 343,461 Elimination of intersegment revenues (63) (41) (28) Consolidated operating revenues 11,879,653 12,147,412 13,764,237 Less Utility expenses and other items: Fuel, fuel-related expenses, and gas purchased for resale 2,214,471 2,755,793 3,634,394 Purchased power 806,646 904,184 1,478,121 Other operation and maintenance expenses 2,851,165 2,838,057 2,899,759 Other regulatory charges (credits) - net (6,133) (138,469) 669,403 Other Utility items (b) 4,109,352 3,152,475 3,340,547 Utility net income 1,830,301 2,510,904 1,398,580 Reconciliation of net income: Non-cash pension settlement charge (c) (319,675) — — IRS audit resolution (d) — 275,403 — Gain on sale of Palisades (e) — — 165,626 Income taxes on reconciling items noted above 66,515 — (36,102) Other loss (203,097) (125,018) (244,949) Elimination of intersegment loss (312,860) (298,979) (186,017) Consolidated net income 1,061,184 2,362,310 1,097,138 Preferred dividend requirements of subsidiaries and noncontrolling interests (f) 5,594 5,774 (6,028) Net income attributable to Entergy Corporation $1,055,590 $2,356,536 $1,103,166 (a) See Note 19 to the financial statements for discussion of other revenues.

Revenue for each integrated utility business is primarily derived from retail electric sales. System Energy has one operating and reportable segment, which is an electricity generation business. System Energy’s only source of revenue is the sale of electric power and capacity generated from its 90% interest in the Grand Gulf nuclear plant to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. Each of the Registrant Subsidiaries’ operations are managed on an integrated basis by that company because of the substantial effect of cost-based rates and regulatory oversight on the business process, cost structures, and operating results.

Revenue for the Utility segment is primarily derived from retail electric sales. The accounting policies of the Utility segment are the same as those described in Note 1 to the financial statements. The Utility segment reflects management’s primary basis of organization with a predominant focus on its utility operations in the Gulf South. Entergy’s chief operating decision maker is its chief executive officer. The chief operating decision maker uses Utility net income in the annual planning process and to monitor budget versus actual results on a monthly basis in assessing financial performance and in determining how to allocate resources. Parent & Other includes the parent company, Entergy Corporation, and other business activity, including Entergy’s non-utility operations business, which is an operating segment that does not meet the quantitative thresholds for determining reportable segments. Entergy’s non-utility operations business owns interests in non-nuclear power plants that sell the electric power produced by those plants to wholesale customers and also provides decommissioning services to nuclear power plants owned by non-affiliated entities in the United States. The following table includes operating revenues and significant expense categories regularly provided to the chief operating decision maker for the Utility segment, a reconciliation of Utility operating revenues to Entergy’s consolidated operating revenues, and a reconciliation of Utility net income to consolidated net income and net income attributable to Entergy Corporation for each of the years presented: 2024 2023 2022 (In Thousands) Utility operating revenues $11,805,802 $12,022,944 $13,420,804 Reconciliation of revenues: Other revenues (a) 73,914 124,509 343,461 Elimination of intersegment revenues (63) (41) (28) Consolidated operating revenues 11,879,653 12,147,412 13,764,237 Less Utility expenses and other items: Fuel, fuel-related expenses, and gas purchased for resale 2,214,471 2,755,793 3,634,394 Purchased power 806,646 904,184 1,478,121 Other operation and maintenance expenses 2,851,165 2,838,057 2,899,759 Other regulatory charges (credits) - net (6,133) (138,469) 669,403 Other Utility items (b) 4,109,352 3,152,475 3,340,547 Utility net income 1,830,301 2,510,904 1,398,580 Reconciliation of net income: Non-cash pension settlement charge (c) (319,675) — — IRS audit resolution (d) — 275,403 — Gain on sale of Palisades (e) — — 165,626 Income taxes on reconciling items noted above 66,515 — (36,102) Other loss (203,097) (125,018) (244,949) Elimination of intersegment loss (312,860) (298,979) (186,017) Consolidated net income 1,061,184 2,362,310 1,097,138 Preferred dividend requirements of subsidiaries and noncontrolling interests (f) 5,594 5,774 (6,028) Net income attributable to Entergy Corporation $1,055,590 $2,356,536 $1,103,166 (a) See Note 19 to the financial statements for discussion of other revenues.

All of Entergy’s goodwill is related to the Utility segment. Registrant Subsidiaries Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas each has one operating and reportable segment, an integrated utility business which includes the generation, transmission, and distribution of electric power; and operation of a small natural gas distribution business at each of Entergy Louisiana and Entergy New Orleans. Revenue for each integrated utility business is primarily derived from retail electric sales. System Energy has one operating and reportable segment, which is an electricity generation business. System Energy’s only source of revenue is the sale of electric power and capacity generated from its 90% interest in the Grand Gulf nuclear plant to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. Each of the Registrant Subsidiaries’ operations are managed on an integrated basis by that company because of the substantial effect of cost-based rates and regulatory oversight on the business process, cost structures, and operating results. The chief operating decision maker for the Registrant Subsidiaries is the respective president and chief executive officer for the Utility operating companies and the president for System Energy. Each chief operating decision maker assesses financial performance on an entity-wide basis and decides how to allocate resources based on net income that also is reported on the income statement for each of the Registrant Subsidiaries as net income. Net income is used in the annual planning process and to monitor budget versus actual results on a monthly basis and each Registrant Subsidiary’s earned return on common equity in assessing financial performance. Each chief operating decision maker is only provided with the consolidated financial results for the respective Registrant Subsidiary. All segment financial information for the Registrant Subsidiaries is as reported on the respective financial statements for each of the Registrant Subsidiaries. Geographic Areas Entergy and the Registrant Subsidiaries derive substantially all revenue from inside of the United States and all long-lived assets are located within the United States.

Held for Sale Natural Gas Distribution Businesses On October 28, 2023, Entergy New Orleans and Entergy Louisiana each entered into separate purchase and sale agreements with respect to the sale of their respective regulated natural gas local distribution company businesses to two separate affiliates of Bernhard Capital Partners Management LP. Under the purchase and sale agreements, Entergy New Orleans has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of Orleans, Louisiana, and Entergy Louisiana has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of East Baton Rouge, Louisiana. The Entergy Louisiana and Entergy New Orleans natural gas distribution businesses are reflected in Entergy’s Utility reportable segment and in the respective single reportable segment for each of Entergy Louisiana and Entergy New Orleans. The base purchase price to be paid by the buyer of the Entergy New Orleans gas business is $285.5 million, and the base purchase price to be paid by the buyer of the Entergy Louisiana gas business is $198 million, in each case subject to certain adjustments at the closing of the transactions. Each purchase and sale agreement contains customary representations, warranties, and covenants related to the applicable business and the respective transactions. Entergy New Orleans and Entergy Louisiana have each agreed to operate the respective gas businesses in the ordinary course of business and subject to certain operating covenants during the period between the date of the purchase and sale agreements and the completion of the transactions. The transactions will proceed in two phases: (1) an “Initial Phase” prior to regulatory approvals in connection with both transactions; and (2) a “Second Phase” following regulatory approvals in connection with both transactions to the extent that certain conditions are satisfied or, where permissible, waived for both transactions. Required regulatory approvals include the approval of the City Council for the sale of the Entergy New Orleans gas business and the approval of the LPSC and the Metropolitan Council for the City of Baton Rouge and Parish of East Baton Rouge for the sale of the Entergy Louisiana gas business. Additionally, while approval of the transactions is generally not required from the FERC, the parties sought and obtained a waiver of the FERC’s capacity release rules, as applicable. In December 2023, Entergy New Orleans and Entergy Louisiana and the respective buyers filed their joint applications with the City Council and the LPSC, respectively, seeking approval for the proposed transactions. The applications requested a decision by June 2024. In February 2024 the City Council adopted a procedural schedule, and in September 2024 the hearing officer certified the record of the proceeding. In December 2024 the City Council found the proposed transaction in the public interest and approved it, subject to certain conditions. The key conditions include: • Entergy New Orleans will not seek recovery of certain assets allocated to its gas business that will not transfer to the buyer through the sale. These assets had a net book value as of December 31, 2024 of approximately $19 million. • Entergy New Orleans will be limited to recovering $19 million of transaction and cooperation costs associated with the sale of the gas business. • Entergy New Orleans will share with customers 50% of the net proceeds from the transaction. Net proceeds from the transaction will be determined by the sales price, less the sum of: (1) the net book value of the assets sold and liabilities assumed by the buyer, (2) the net book value of the assets of the gas business that will not be included in the sale and for which Entergy New Orleans will not seek to recover from customers, and (3) the transaction and cooperation costs associated with the sale, limited to $19 million. Entergy New Orleans will recognize a regulatory liability for such sharing with customers, and will amortize it into customer rates ratably over three years. In July 2024 the LPSC staff issued a report recommending LPSC approval of the application of Delta Capital Gas Company, LLC (a Bernhard Capital Partners Management LP affiliate, formerly Delta States Utilities LA, LLC) and Entergy Louisiana and the transaction described therein as being in the public interest and proposing certain conditions. In August 2024 the LPSC issued an order accepting the LPSC staff’s report and recommendation. The purchase and sale agreements may be terminated by any party if the Second Phase does not start within 15 months of October 28, 2023, or within 18 months if the only remaining conditions to starting the Second Phase are obtaining the regulatory approvals. The consummation of each of the transactions is subject to satisfaction of certain customary closing conditions, including the receipt of the regulatory approvals, clearance under the Hart-Scott Rodino Act, and the concurrent closing of the other transaction. Clearance under the Hart-Scott Rodino Act was obtained in 2024. Under the purchase and sale agreements, the closing of the transactions is not required to occur earlier than the later of six months following the initiation of the Second Phase and July 28, 2025, and the purchase and sale agreements may be terminated by either party in the event the closing has not occurred prior to October 28, 2025. Neither transaction is subject to a financing condition for the applicable buyer. The purchase and sale agreements are subject to customary termination provisions. If the purchase and sale agreements are terminated in certain circumstances, each seller may be liable to the applicable buyer for a portion of the buyer’s transition costs incurred in connection with transitioning the applicable business. Entergy New Orleans’s and Entergy Louisiana’s aggregate liability for such transaction costs shall not exceed $7.5 million if termination occurs during the Initial Phase or $12.5 million if termination occurs during the Second Phase, with responsibility allocated between the sellers pro rata based on the relative purchase price. If the purchase and sale agreements are terminated in certain circumstances, each buyer may be liable to the corresponding seller for a reverse termination fee, equal to 7% of the applicable base purchase price if termination occurs during the Initial Phase, or 10% of the applicable base purchase price if the termination occurs in the Second Phase. As of December 31, 2024, the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses met the criteria to be classified as held for sale. Neither Entergy Louisiana nor Entergy New Orleans recognized write downs of the natural gas distribution business assets as a result of their classification as held for sale as of December 31, 2024, as neither sale is expected to result in a loss.

Held for Sale Natural Gas Distribution Businesses On October 28, 2023, Entergy New Orleans and Entergy Louisiana each entered into separate purchase and sale agreements with respect to the sale of their respective regulated natural gas local distribution company businesses to two separate affiliates of Bernhard Capital Partners Management LP. Under the purchase and sale agreements, Entergy New Orleans has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of Orleans, Louisiana, and Entergy Louisiana has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of East Baton Rouge, Louisiana. The Entergy Louisiana and Entergy New Orleans natural gas distribution businesses are reflected in Entergy’s Utility reportable segment and in the respective single reportable segment for each of Entergy Louisiana and Entergy New Orleans. The base purchase price to be paid by the buyer of the Entergy New Orleans gas business is $285.5 million, and the base purchase price to be paid by the buyer of the Entergy Louisiana gas business is $198 million, in each case subject to certain adjustments at the closing of the transactions. Each purchase and sale agreement contains customary representations, warranties, and covenants related to the applicable business and the respective transactions. Entergy New Orleans and Entergy Louisiana have each agreed to operate the respective gas businesses in the ordinary course of business and subject to certain operating covenants during the period between the date of the purchase and sale agreements and the completion of the transactions. The transactions will proceed in two phases: (1) an “Initial Phase” prior to regulatory approvals in connection with both transactions; and (2) a “Second Phase” following regulatory approvals in connection with both transactions to the extent that certain conditions are satisfied or, where permissible, waived for both transactions. Required regulatory approvals include the approval of the City Council for the sale of the Entergy New Orleans gas business and the approval of the LPSC and the Metropolitan Council for the City of Baton Rouge and Parish of East Baton Rouge for the sale of the Entergy Louisiana gas business. Additionally, while approval of the transactions is generally not required from the FERC, the parties sought and obtained a waiver of the FERC’s capacity release rules, as applicable. In December 2023, Entergy New Orleans and Entergy Louisiana and the respective buyers filed their joint applications with the City Council and the LPSC, respectively, seeking approval for the proposed transactions. The applications requested a decision by June 2024. In February 2024 the City Council adopted a procedural schedule, and in September 2024 the hearing officer certified the record of the proceeding. In December 2024 the City Council found the proposed transaction in the public interest and approved it, subject to certain conditions. The key conditions include: • Entergy New Orleans will not seek recovery of certain assets allocated to its gas business that will not transfer to the buyer through the sale. These assets had a net book value as of December 31, 2024 of approximately $19 million. • Entergy New Orleans will be limited to recovering $19 million of transaction and cooperation costs associated with the sale of the gas business. • Entergy New Orleans will share with customers 50% of the net proceeds from the transaction. Net proceeds from the transaction will be determined by the sales price, less the sum of: (1) the net book value of the assets sold and liabilities assumed by the buyer, (2) the net book value of the assets of the gas business that will not be included in the sale and for which Entergy New Orleans will not seek to recover from customers, and (3) the transaction and cooperation costs associated with the sale, limited to $19 million. Entergy New Orleans will recognize a regulatory liability for such sharing with customers, and will amortize it into customer rates ratably over three years. In July 2024 the LPSC staff issued a report recommending LPSC approval of the application of Delta Capital Gas Company, LLC (a Bernhard Capital Partners Management LP affiliate, formerly Delta States Utilities LA, LLC) and Entergy Louisiana and the transaction described therein as being in the public interest and proposing certain conditions. In August 2024 the LPSC issued an order accepting the LPSC staff’s report and recommendation. The purchase and sale agreements may be terminated by any party if the Second Phase does not start within 15 months of October 28, 2023, or within 18 months if the only remaining conditions to starting the Second Phase are obtaining the regulatory approvals. The consummation of each of the transactions is subject to satisfaction of certain customary closing conditions, including the receipt of the regulatory approvals, clearance under the Hart-Scott Rodino Act, and the concurrent closing of the other transaction. Clearance under the Hart-Scott Rodino Act was obtained in 2024. Under the purchase and sale agreements, the closing of the transactions is not required to occur earlier than the later of six months following the initiation of the Second Phase and July 28, 2025, and the purchase and sale agreements may be terminated by either party in the event the closing has not occurred prior to October 28, 2025. Neither transaction is subject to a financing condition for the applicable buyer. The purchase and sale agreements are subject to customary termination provisions. If the purchase and sale agreements are terminated in certain circumstances, each seller may be liable to the applicable buyer for a portion of the buyer’s transition costs incurred in connection with transitioning the applicable business. Entergy New Orleans’s and Entergy Louisiana’s aggregate liability for such transaction costs shall not exceed $7.5 million if termination occurs during the Initial Phase or $12.5 million if termination occurs during the Second Phase, with responsibility allocated between the sellers pro rata based on the relative purchase price. If the purchase and sale agreements are terminated in certain circumstances, each buyer may be liable to the corresponding seller for a reverse termination fee, equal to 7% of the applicable base purchase price if termination occurs during the Initial Phase, or 10% of the applicable base purchase price if the termination occurs in the Second Phase. As of December 31, 2024, the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses met the criteria to be classified as held for sale. Neither Entergy Louisiana nor Entergy New Orleans recognized write downs of the natural gas distribution business assets as a result of their classification as held for sale as of December 31, 2024, as neither sale is expected to result in a loss.

Entergy New Orleans and Entergy Louisiana have each agreed to operate the respective gas businesses in the ordinary course of business and subject to certain operating covenants during the period between the date of the purchase and sale agreements and the completion of the transactions. The transactions will proceed in two phases: (1) an “Initial Phase” prior to regulatory approvals in connection with both transactions; and (2) a “Second Phase” following regulatory approvals in connection with both transactions to the extent that certain conditions are satisfied or, where permissible, waived for both transactions. Required regulatory approvals include the approval of the City Council for the sale of the Entergy New Orleans gas business and the approval of the LPSC and the Metropolitan Council for the City of Baton Rouge and Parish of East Baton Rouge for the sale of the Entergy Louisiana gas business. Additionally, while approval of the transactions is generally not required from the FERC, the parties sought and obtained a waiver of the FERC’s capacity release rules, as applicable. In December 2023, Entergy New Orleans and Entergy Louisiana and the respective buyers filed their joint applications with the City Council and the LPSC, respectively, seeking approval for the proposed transactions. The applications requested a decision by June 2024. In February 2024 the City Council adopted a procedural schedule, and in September 2024 the hearing officer certified the record of the proceeding. In December 2024 the City Council found the proposed transaction in the public interest and approved it, subject to certain conditions. The key conditions include: • Entergy New Orleans will not seek recovery of certain assets allocated to its gas business that will not transfer to the buyer through the sale. These assets had a net book value as of December 31, 2024 of approximately $19 million. • Entergy New Orleans will be limited to recovering $19 million of transaction and cooperation costs associated with the sale of the gas business. • Entergy New Orleans will share with customers 50% of the net proceeds from the transaction. Net proceeds from the transaction will be determined by the sales price, less the sum of: (1) the net book value of the assets sold and liabilities assumed by the buyer, (2) the net book value of the assets of the gas business that will not be included in the sale and for which Entergy New Orleans will not seek to recover from customers, and (3) the transaction and cooperation costs associated with the sale, limited to $19 million. Entergy New Orleans will recognize a regulatory liability for such sharing with customers, and will amortize it into customer rates ratably over three years. In July 2024 the LPSC staff issued a report recommending LPSC approval of the application of Delta Capital Gas Company, LLC (a Bernhard Capital Partners Management LP affiliate, formerly Delta States Utilities LA, LLC) and Entergy Louisiana and the transaction described therein as being in the public interest and proposing certain conditions. In August 2024 the LPSC issued an order accepting the LPSC staff’s report and recommendation. The purchase and sale agreements may be terminated by any party if the Second Phase does not start within 15 months of October 28, 2023, or within 18 months if the only remaining conditions to starting the Second Phase are obtaining the regulatory approvals. The consummation of each of the transactions is subject to satisfaction of certain customary closing conditions, including the receipt of the regulatory approvals, clearance under the Hart-Scott Rodino Act, and the concurrent closing of the other transaction. Clearance under the Hart-Scott Rodino Act was obtained in 2024. Under the purchase and sale agreements, the closing of the transactions is not required to occur earlier than the later of six months following the initiation of the Second Phase and July 28, 2025, and the purchase and sale agreements may be terminated by either party in the event the closing has not occurred prior to October 28, 2025. Neither transaction is subject to a financing condition for the applicable buyer. The purchase and sale agreements are subject to customary termination provisions. If the purchase and sale agreements are terminated in certain circumstances, each seller may be liable to the applicable buyer for a portion of the buyer’s transition costs incurred in connection with transitioning the applicable business. Entergy New Orleans’s and Entergy Louisiana’s aggregate liability for such transaction costs shall not exceed $7.5 million if termination occurs during the Initial Phase or $12.5 million if termination occurs during the Second Phase, with responsibility allocated between the sellers pro rata based on the relative purchase price. If the purchase and sale agreements are terminated in certain circumstances, each buyer may be liable to the corresponding seller for a reverse termination fee, equal to 7% of the applicable base purchase price if termination occurs during the Initial Phase, or 10% of the applicable base purchase price if the termination occurs in the Second Phase. As of December 31, 2024, the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses met the criteria to be classified as held for sale. Neither Entergy Louisiana nor Entergy New Orleans recognized write downs of the natural gas distribution business assets as a result of their classification as held for sale as of December 31, 2024, as neither sale is expected to result in a loss. The assets and liabilities of the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses classified as held for sale on Entergy’s, Entergy Louisiana’s, and Entergy New Orleans’s consolidated balance sheets as of December 31, 2024 included the following amounts: Entergy Entergy Louisiana Entergy New Orleans (In Thousands) Deferred fuel $5,608 $727 $4,881 Fuel inventory - at average cost 4,493 702 3,791 Materials and supplies 5,451 1,045 4,406 Prepayments and other 22 — 22 Total current assets held for sale $15,574 $2,474 $13,100 Property, plant, and equipment - natural gas $679,502 $303,193 $376,309 Construction work in progress 2,959 1,085 1,874 Less - accumulated depreciation and amortization (276,388) (139,556) (136,832) Other regulatory assets 35,381 8,947 23,682 Goodwill (a) 6,474 — — Pension and other postretirement assets 14,663 — 19,499 Other 206 — 206 Total non-current assets held for sale $462,797 $173,669 $284,738 Accounts payable $702 $702 $— Customer deposits 6,214 1,984 4,230 Taxes accrued 13 13 — Other 1,401 589 812 Total current liabilities held for sale (b) $8,330 $3,288 $5,042 Regulatory liability for income taxes - net $31,575 $4,981 $26,594 Other regulatory liabilities 1,611 1,214 397 Pension and other postretirement liabilities 3,976 4,525 1,197 Other 3,844 1,194 2,650 Total non-current liabilities held for sale (c) $41,006 $11,914 $30,838 (a) Goodwill is allocated to the natural gas distribution business based on its relative fair value compared to the retained portion of the reporting unit. (b) Included within other current liabilities on the respective consolidated balance sheets. (c) Included within other non-current liabilities on the respective consolidated balance sheets. Entergy Louisiana and Entergy New Orleans will continue to recognize depreciation on the natural gas distribution businesses assets since they will continue to receive revenues through utility customer rates until the closing of the transaction, and because the final purchase price for the natural gas distribution businesses will be adjusted by an amount equal to that depreciation, among other adjustments. The pre-tax income for the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses, excluding interest and corporate allocations, included in Entergy’s, Entergy Louisiana’s, and Entergy New Orleans’s consolidated income statements for the years ended December 31, 2024, 2023, and 2022 is as follows: 2024 2023 2022 (In Thousands) Entergy Income before income taxes $48,223 $38,162 $39,076 Entergy Louisiana Income before income taxes $20,965 $17,375 $15,080 Entergy New Orleans Income before income taxes $27,258 $20,787 $23,996 Dispositions Palisades In July 2018, Entergy entered into a purchase and sale agreement with Holtec International to sell to a Holtec subsidiary 100% of the equity interests in the subsidiary that owns Palisades and the Big Rock Point Site. In December 2020, Entergy and Holtec submitted a license transfer application to the NRC requesting approval to transfer the Palisades and Big Rock Point licenses from Entergy to Holtec. The NRC issued an order approving the application in December 2021. Palisades was shut down in May 2022 and defueled in June 2022. The Palisades transaction closed in June 2022 for a purchase price of $1,000 (subject to adjustment for net liabilities and other amounts). The sale included the transfer of the Palisades nuclear decommissioning trust and the asset retirement obligation for spent fuel management and plant decommissioning. The transaction resulted in a gain of $166 million ($130 million net-of-tax) in the second quarter 2022. The disposition-date fair value of the nuclear decommissioning trust fund was approximately $552 million, and the disposition-date fair value of the asset retirement obligation was approximately $708 million. The transaction also included property, plant, and equipment with a net book value of zero and materials and supplies.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Market Risk In the normal course of business, Entergy is exposed to a number of market risks. Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument. All financial and commodity-related instruments, including derivatives, are subject to market risk including commodity price risk, equity price, and interest rate risk. Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel. The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation. To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers. Derivatives Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments. Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps and options that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps and options are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps and options as of December 31, 2024 is 10 months for Entergy Mississippi. The total volume of natural gas swaps and options outstanding as of December 31, 2024 is 9,603,850 MMBtu for Entergy and Entergy Mississippi. As of December 31, 2024, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps or options. Credit support for these natural gas swaps and options is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral. During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of December 31, 2024 is 59,318 GWh for Entergy, including 13,991 GWh for Entergy Arkansas, 24,896 GWh for Entergy Louisiana, 9,297 GWh for Entergy Mississippi, 2,460 GWh for Entergy New Orleans, and 8,579 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of December 31, 2024 and 2023. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024 and for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy Texas as of December 31, 2023.

The gains or losses recorded as fuel expenses when the swaps and options are settled are recovered or refunded through fuel cost recovery mechanisms. (b) Due to regulatory treatment, the changes in the estimated fair value of financial transmission rights for the Utility operating companies are recorded through purchased power expense and then such amounts are simultaneously reversed and recorded as an offsetting regulatory asset or liability. The gains or losses recorded as purchased power expense when the financial transmission rights for the Utility operating companies are settled are recovered or refunded through fuel cost recovery mechanisms. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market participants at the date of measurement. Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value. The inputs can be readily observable, corroborated by market data, or generally unobservable. Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs. The three levels of the fair value hierarchy are: • Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets. Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase. • Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date. Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value. Level 2 inputs include the following: – quoted prices for similar assets or liabilities in active markets; – quoted prices for identical assets or liabilities in inactive markets; – inputs other than quoted prices that are observable for the asset or liability; or – inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 consists primarily of individually-owned debt instruments and gas swaps and options valued using observable inputs. • Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources. These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability. Level 3 consists primarily of financial transmission rights. The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices. They are classified as Level 3 assets and liabilities. The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight. The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer. The Accounting group reports to the Chief Accounting Officer. The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of December 31, 2024 and December 31, 2023. The assessment of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. 2024 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $811 $— $— $811 Decommissioning trust funds (a): Equity securities 30 — — 30 Debt securities 848 1,199 — 2,047 Common trusts (b) 3,486 Securitization recovery trust account 4 — — 4 Storm reserve escrow accounts 340 — — 340 Natural gas swaps and options 2 — — 2 Financial transmission rights — — 20 20 $2,035 $1,199 $20 $6,740 Liabilities: Financial transmission rights $— $— $1 $1 2023 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $61 $— $— $61 Decommissioning trust funds (a): Equity securities 24 — — 24 Debt securities 611 1,159 — 1,770 Common trusts (b) 3,070 Securitization recovery trust account 8 — — 8 Storm reserve escrow accounts 323 — — 323 Financial transmission rights — — 21 21 $1,027 $1,159 $21 $5,277 Liabilities: Natural gas swaps and options $11 $— $— $11 (a) The decommissioning trust funds hold equity and fixed income securities.

Entergy Arkansas [Member]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Market Risk In the normal course of business, Entergy is exposed to a number of market risks. Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument. All financial and commodity-related instruments, including derivatives, are subject to market risk including commodity price risk, equity price, and interest rate risk. Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel. The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation. To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers. Derivatives Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments. Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps and options that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps and options are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps and options as of December 31, 2024 is 10 months for Entergy Mississippi. The total volume of natural gas swaps and options outstanding as of December 31, 2024 is 9,603,850 MMBtu for Entergy and Entergy Mississippi. As of December 31, 2024, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps or options. Credit support for these natural gas swaps and options is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral. During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of December 31, 2024 is 59,318 GWh for Entergy, including 13,991 GWh for Entergy Arkansas, 24,896 GWh for Entergy Louisiana, 9,297 GWh for Entergy Mississippi, 2,460 GWh for Entergy New Orleans, and 8,579 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of December 31, 2024 and 2023. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024 and for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy Texas as of December 31, 2023.

Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market participants at the date of measurement. Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value. The inputs can be readily observable, corroborated by market data, or generally unobservable. Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs. The three levels of the fair value hierarchy are: • Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets. Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase. • Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date. Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value. Level 2 inputs include the following: – quoted prices for similar assets or liabilities in active markets; – quoted prices for identical assets or liabilities in inactive markets; – inputs other than quoted prices that are observable for the asset or liability; or – inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 consists primarily of individually-owned debt instruments and gas swaps and options valued using observable inputs. • Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources. These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability. Level 3 consists primarily of financial transmission rights. The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices. They are classified as Level 3 assets and liabilities. The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight. The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer. The Accounting group reports to the Chief Accounting Officer. The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of December 31, 2024 and December 31, 2023. The assessment of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. 2024 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $811 $— $— $811 Decommissioning trust funds (a): Equity securities 30 — — 30 Debt securities 848 1,199 — 2,047 Common trusts (b) 3,486 Securitization recovery trust account 4 — — 4 Storm reserve escrow accounts 340 — — 340 Natural gas swaps and options 2 — — 2 Financial transmission rights — — 20 20 $2,035 $1,199 $20 $6,740 Liabilities: Financial transmission rights $— $— $1 $1 2023 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $61 $— $— $61 Decommissioning trust funds (a): Equity securities 24 — — 24 Debt securities 611 1,159 — 1,770 Common trusts (b) 3,070 Securitization recovery trust account 8 — — 8 Storm reserve escrow accounts 323 — — 323 Financial transmission rights — — 21 21 $1,027 $1,159 $21 $5,277 Liabilities: Natural gas swaps and options $11 $— $— $11 (a) The decommissioning trust funds hold equity and fixed income securities.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Market Risk In the normal course of business, Entergy is exposed to a number of market risks. Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument. All financial and commodity-related instruments, including derivatives, are subject to market risk including commodity price risk, equity price, and interest rate risk. Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel. The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation. To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers. Derivatives Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments. Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps and options that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps and options are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps and options as of December 31, 2024 is 10 months for Entergy Mississippi. The total volume of natural gas swaps and options outstanding as of December 31, 2024 is 9,603,850 MMBtu for Entergy and Entergy Mississippi. As of December 31, 2024, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps or options. Credit support for these natural gas swaps and options is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral. During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of December 31, 2024 is 59,318 GWh for Entergy, including 13,991 GWh for Entergy Arkansas, 24,896 GWh for Entergy Louisiana, 9,297 GWh for Entergy Mississippi, 2,460 GWh for Entergy New Orleans, and 8,579 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of December 31, 2024 and 2023. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024 and for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy Texas as of December 31, 2023. The fair values of Entergy’s derivative instruments not designated as hedging instruments on the consolidated balance sheets as of December 31, 2024 and 2023 are shown in the table below.

Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market participants at the date of measurement. Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value. The inputs can be readily observable, corroborated by market data, or generally unobservable. Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs. The three levels of the fair value hierarchy are: • Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets. Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase. • Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date. Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value. Level 2 inputs include the following: – quoted prices for similar assets or liabilities in active markets; – quoted prices for identical assets or liabilities in inactive markets; – inputs other than quoted prices that are observable for the asset or liability; or – inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 consists primarily of individually-owned debt instruments and gas swaps and options valued using observable inputs. • Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources. These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability. Level 3 consists primarily of financial transmission rights. The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices. They are classified as Level 3 assets and liabilities. The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight. The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer. The Accounting group reports to the Chief Accounting Officer. The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of December 31, 2024 and December 31, 2023. The assessment of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. 2024 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $811 $— $— $811 Decommissioning trust funds (a): Equity securities 30 — — 30 Debt securities 848 1,199 — 2,047 Common trusts (b) 3,486 Securitization recovery trust account 4 — — 4 Storm reserve escrow accounts 340 — — 340 Natural gas swaps and options 2 — — 2 Financial transmission rights — — 20 20 $2,035 $1,199 $20 $6,740 Liabilities: Financial transmission rights $— $— $1 $1 2023 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $61 $— $— $61 Decommissioning trust funds (a): Equity securities 24 — — 24 Debt securities 611 1,159 — 1,770 Common trusts (b) 3,070 Securitization recovery trust account 8 — — 8 Storm reserve escrow accounts 323 — — 323 Financial transmission rights — — 21 21 $1,027 $1,159 $21 $5,277 Liabilities: Natural gas swaps and options $11 $— $— $11 (a) The decommissioning trust funds hold equity and fixed income securities.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Market Risk In the normal course of business, Entergy is exposed to a number of market risks. Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument. All financial and commodity-related instruments, including derivatives, are subject to market risk including commodity price risk, equity price, and interest rate risk. Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel. The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation. To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers. Derivatives Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments. Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps and options that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps and options are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps and options as of December 31, 2024 is 10 months for Entergy Mississippi. The total volume of natural gas swaps and options outstanding as of December 31, 2024 is 9,603,850 MMBtu for Entergy and Entergy Mississippi. As of December 31, 2024, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps or options. Credit support for these natural gas swaps and options is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral. During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of December 31, 2024 is 59,318 GWh for Entergy, including 13,991 GWh for Entergy Arkansas, 24,896 GWh for Entergy Louisiana, 9,297 GWh for Entergy Mississippi, 2,460 GWh for Entergy New Orleans, and 8,579 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of December 31, 2024 and 2023. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024 and for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy Texas as of December 31, 2023. The fair values of Entergy’s derivative instruments not designated as hedging instruments on the consolidated balance sheets as of December 31, 2024 and 2023 are shown in the table below.

The gains or losses recorded as purchased power expense when the financial transmission rights for the Utility operating companies are settled are recovered or refunded through fuel cost recovery mechanisms. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market participants at the date of measurement. Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value. The inputs can be readily observable, corroborated by market data, or generally unobservable. Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs. The three levels of the fair value hierarchy are: • Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets. Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase. • Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date. Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value. Level 2 inputs include the following: – quoted prices for similar assets or liabilities in active markets; – quoted prices for identical assets or liabilities in inactive markets; – inputs other than quoted prices that are observable for the asset or liability; or – inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 consists primarily of individually-owned debt instruments and gas swaps and options valued using observable inputs. • Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources. These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability. Level 3 consists primarily of financial transmission rights. The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices. They are classified as Level 3 assets and liabilities. The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight. The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer. The Accounting group reports to the Chief Accounting Officer. The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of December 31, 2024 and December 31, 2023. The assessment of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. 2024 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $811 $— $— $811 Decommissioning trust funds (a): Equity securities 30 — — 30 Debt securities 848 1,199 — 2,047 Common trusts (b) 3,486 Securitization recovery trust account 4 — — 4 Storm reserve escrow accounts 340 — — 340 Natural gas swaps and options 2 — — 2 Financial transmission rights — — 20 20 $2,035 $1,199 $20 $6,740 Liabilities: Financial transmission rights $— $— $1 $1 2023 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $61 $— $— $61 Decommissioning trust funds (a): Equity securities 24 — — 24 Debt securities 611 1,159 — 1,770 Common trusts (b) 3,070 Securitization recovery trust account 8 — — 8 Storm reserve escrow accounts 323 — — 323 Financial transmission rights — — 21 21 $1,027 $1,159 $21 $5,277 Liabilities: Natural gas swaps and options $11 $— $— $11 (a) The decommissioning trust funds hold equity and fixed income securities.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Market Risk In the normal course of business, Entergy is exposed to a number of market risks. Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument. All financial and commodity-related instruments, including derivatives, are subject to market risk including commodity price risk, equity price, and interest rate risk. Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel. The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation. To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers. Derivatives Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments. Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps and options that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps and options are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps and options as of December 31, 2024 is 10 months for Entergy Mississippi. The total volume of natural gas swaps and options outstanding as of December 31, 2024 is 9,603,850 MMBtu for Entergy and Entergy Mississippi. As of December 31, 2024, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps or options. Credit support for these natural gas swaps and options is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral. During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of December 31, 2024 is 59,318 GWh for Entergy, including 13,991 GWh for Entergy Arkansas, 24,896 GWh for Entergy Louisiana, 9,297 GWh for Entergy Mississippi, 2,460 GWh for Entergy New Orleans, and 8,579 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of December 31, 2024 and 2023. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024 and for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy Texas as of December 31, 2023. The fair values of Entergy’s derivative instruments not designated as hedging instruments on the consolidated balance sheets as of December 31, 2024 and 2023 are shown in the table below.

The gains or losses recorded as purchased power expense when the financial transmission rights for the Utility operating companies are settled are recovered or refunded through fuel cost recovery mechanisms. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market participants at the date of measurement. Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value. The inputs can be readily observable, corroborated by market data, or generally unobservable. Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs. The three levels of the fair value hierarchy are: • Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets. Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase. • Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date. Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value. Level 2 inputs include the following: – quoted prices for similar assets or liabilities in active markets; – quoted prices for identical assets or liabilities in inactive markets; – inputs other than quoted prices that are observable for the asset or liability; or – inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 consists primarily of individually-owned debt instruments and gas swaps and options valued using observable inputs. • Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources. These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability. Level 3 consists primarily of financial transmission rights. The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices. They are classified as Level 3 assets and liabilities. The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight. The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer. The Accounting group reports to the Chief Accounting Officer. The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of December 31, 2024 and December 31, 2023. The assessment of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. 2024 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $811 $— $— $811 Decommissioning trust funds (a): Equity securities 30 — — 30 Debt securities 848 1,199 — 2,047 Common trusts (b) 3,486 Securitization recovery trust account 4 — — 4 Storm reserve escrow accounts 340 — — 340 Natural gas swaps and options 2 — — 2 Financial transmission rights — — 20 20 $2,035 $1,199 $20 $6,740 Liabilities: Financial transmission rights $— $— $1 $1 2023 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $61 $— $— $61 Decommissioning trust funds (a): Equity securities 24 — — 24 Debt securities 611 1,159 — 1,770 Common trusts (b) 3,070 Securitization recovery trust account 8 — — 8 Storm reserve escrow accounts 323 — — 323 Financial transmission rights — — 21 21 $1,027 $1,159 $21 $5,277 Liabilities: Natural gas swaps and options $11 $— $— $11 (a) The decommissioning trust funds hold equity and fixed income securities.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Market Risk In the normal course of business, Entergy is exposed to a number of market risks. Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument. All financial and commodity-related instruments, including derivatives, are subject to market risk including commodity price risk, equity price, and interest rate risk. Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel. The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation. To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers. Derivatives Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments. Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps and options that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps and options are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps and options as of December 31, 2024 is 10 months for Entergy Mississippi. The total volume of natural gas swaps and options outstanding as of December 31, 2024 is 9,603,850 MMBtu for Entergy and Entergy Mississippi. As of December 31, 2024, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps or options. Credit support for these natural gas swaps and options is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral. During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of December 31, 2024 is 59,318 GWh for Entergy, including 13,991 GWh for Entergy Arkansas, 24,896 GWh for Entergy Louisiana, 9,297 GWh for Entergy Mississippi, 2,460 GWh for Entergy New Orleans, and 8,579 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of December 31, 2024 and 2023. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024 and for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy Texas as of December 31, 2023. The fair values of Entergy’s derivative instruments not designated as hedging instruments on the consolidated balance sheets as of December 31, 2024 and 2023 are shown in the table below.

The gains or losses recorded as purchased power expense when the financial transmission rights for the Utility operating companies are settled are recovered or refunded through fuel cost recovery mechanisms. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market participants at the date of measurement. Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value. The inputs can be readily observable, corroborated by market data, or generally unobservable. Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs. The three levels of the fair value hierarchy are: • Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets. Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase. • Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date. Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value. Level 2 inputs include the following: – quoted prices for similar assets or liabilities in active markets; – quoted prices for identical assets or liabilities in inactive markets; – inputs other than quoted prices that are observable for the asset or liability; or – inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 consists primarily of individually-owned debt instruments and gas swaps and options valued using observable inputs. • Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources. These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability. Level 3 consists primarily of financial transmission rights. The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices. They are classified as Level 3 assets and liabilities. The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight. The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer. The Accounting group reports to the Chief Accounting Officer. The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of December 31, 2024 and December 31, 2023. The assessment of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. 2024 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $811 $— $— $811 Decommissioning trust funds (a): Equity securities 30 — — 30 Debt securities 848 1,199 — 2,047 Common trusts (b) 3,486 Securitization recovery trust account 4 — — 4 Storm reserve escrow accounts 340 — — 340 Natural gas swaps and options 2 — — 2 Financial transmission rights — — 20 20 $2,035 $1,199 $20 $6,740 Liabilities: Financial transmission rights $— $— $1 $1 2023 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $61 $— $— $61 Decommissioning trust funds (a): Equity securities 24 — — 24 Debt securities 611 1,159 — 1,770 Common trusts (b) 3,070 Securitization recovery trust account 8 — — 8 Storm reserve escrow accounts 323 — — 323 Financial transmission rights — — 21 21 $1,027 $1,159 $21 $5,277 Liabilities: Natural gas swaps and options $11 $— $— $11 (a) The decommissioning trust funds hold equity and fixed income securities.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Market Risk In the normal course of business, Entergy is exposed to a number of market risks. Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument. All financial and commodity-related instruments, including derivatives, are subject to market risk including commodity price risk, equity price, and interest rate risk. Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel. The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation. To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers. Derivatives Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments. Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps and options that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps and options are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps and options as of December 31, 2024 is 10 months for Entergy Mississippi. The total volume of natural gas swaps and options outstanding as of December 31, 2024 is 9,603,850 MMBtu for Entergy and Entergy Mississippi. As of December 31, 2024, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps or options. Credit support for these natural gas swaps and options is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral. During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of December 31, 2024 is 59,318 GWh for Entergy, including 13,991 GWh for Entergy Arkansas, 24,896 GWh for Entergy Louisiana, 9,297 GWh for Entergy Mississippi, 2,460 GWh for Entergy New Orleans, and 8,579 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of December 31, 2024 and 2023. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024 and for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy Texas as of December 31, 2023. The fair values of Entergy’s derivative instruments not designated as hedging instruments on the consolidated balance sheets as of December 31, 2024 and 2023 are shown in the table below.

The gains or losses recorded as purchased power expense when the financial transmission rights for the Utility operating companies are settled are recovered or refunded through fuel cost recovery mechanisms. Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market participants at the date of measurement. Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value. The inputs can be readily observable, corroborated by market data, or generally unobservable. Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs. The three levels of the fair value hierarchy are: • Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets. Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase. • Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date. Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value. Level 2 inputs include the following: – quoted prices for similar assets or liabilities in active markets; – quoted prices for identical assets or liabilities in inactive markets; – inputs other than quoted prices that are observable for the asset or liability; or – inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 consists primarily of individually-owned debt instruments and gas swaps and options valued using observable inputs. • Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources. These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability. Level 3 consists primarily of financial transmission rights. The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices. They are classified as Level 3 assets and liabilities. The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight. The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer. The Accounting group reports to the Chief Accounting Officer. The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of December 31, 2024 and December 31, 2023. The assessment of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. 2024 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $811 $— $— $811 Decommissioning trust funds (a): Equity securities 30 — — 30 Debt securities 848 1,199 — 2,047 Common trusts (b) 3,486 Securitization recovery trust account 4 — — 4 Storm reserve escrow accounts 340 — — 340 Natural gas swaps and options 2 — — 2 Financial transmission rights — — 20 20 $2,035 $1,199 $20 $6,740 Liabilities: Financial transmission rights $— $— $1 $1 2023 Level 1 Level 2 Level 3 Total (In Millions) Assets: Temporary cash investments $61 $— $— $61 Decommissioning trust funds (a): Equity securities 24 — — 24 Debt securities 611 1,159 — 1,770 Common trusts (b) 3,070 Securitization recovery trust account 8 — — 8 Storm reserve escrow accounts 323 — — 323 Financial transmission rights — — 21 21 $1,027 $1,159 $21 $5,277 Liabilities: Natural gas swaps and options $11 $— $— $11 (a) The decommissioning trust funds hold equity and fixed income securities.

Decommissioning Trust Fund [Text Block]	DECOMMISSIONING TRUST FUNDS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, and System Energy) The NRC requires certain of the Utility operating companies and System Energy to maintain nuclear decommissioning trusts to fund the costs of decommissioning ANO 1 and 2, River Bend, Waterford 3, and Grand Gulf. Entergy’s nuclear decommissioning trust funds invest in equity securities, fixed-rate debt securities, and cash and cash equivalents. Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Generally, Entergy records gains and losses on its debt and equity securities using the specific identification method to determine the cost basis of its securities. As discussed in Note 14 to the financial statements, in June 2022, Entergy completed the sale of Palisades to Holtec. As part of the transaction, Entergy transferred the Palisades decommissioning trust fund to Holtec. The disposition-date fair value of the decommissioning trust fund was approximately $552 million. The unrealized gains/(losses) recognized during the year ended December 31, 2024 on equity securities still held as of December 31, 2024 were $616 million. The equity securities are generally held in funds that are designed to approximate or somewhat exceed the return of the Standard & Poor’s 500 Index. A relatively small percentage of the equity securities are held in funds that are designed to approximate or somewhat exceed the return of the Wilshire 4500 Index. The debt securities are generally held in individual government and credit issuances.

Decommissioning Trust Fund [Text Block]	DECOMMISSIONING TRUST FUNDS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, and System Energy) The NRC requires certain of the Utility operating companies and System Energy to maintain nuclear decommissioning trusts to fund the costs of decommissioning ANO 1 and 2, River Bend, Waterford 3, and Grand Gulf. Entergy’s nuclear decommissioning trust funds invest in equity securities, fixed-rate debt securities, and cash and cash equivalents. Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Generally, Entergy records gains and losses on its debt and equity securities using the specific identification method to determine the cost basis of its securities. As discussed in Note 14 to the financial statements, in June 2022, Entergy completed the sale of Palisades to Holtec.

Variable Interest Entity Disclosure [Text Block]	VARIABLE INTEREST ENTITIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Under applicable authoritative accounting guidance, a variable interest entity (VIE) is an entity that conducts a business or holds property that possesses any of the following characteristics: an insufficient amount of equity at risk to finance its activities, equity owners who do not have the power to direct the significant activities of the entity (or have voting rights that are disproportionate to their ownership interest), or where equity holders do not receive expected losses or returns. An entity may have an interest in a VIE through ownership or other contractual rights or obligations, and is required to consolidate a VIE if it is the VIE’s primary beneficiary. The primary beneficiary of a VIE is the entity that has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and has the obligation to absorb losses or has the right to residual returns that would potentially be significant to the entity. Entergy Arkansas, Entergy Louisiana, and System Energy consolidate the respective companies from which they lease nuclear fuel, usually in a sale and leaseback transaction. This is because Entergy directs the nuclear fuel companies with respect to nuclear fuel purchases, assists the nuclear fuel companies in obtaining financing, and, if financing cannot be arranged, the lessee (Entergy Arkansas, Entergy Louisiana, or System Energy) is required to pay advance rent (Entergy Arkansas VIE, Entergy Louisiana Waterford VIE, and System Energy VIE) or special payments (Entergy Louisiana River Bend VIE) to allow the nuclear fuel company (the VIE) to meet its obligations. During the term of the arrangements, none of the Entergy operating companies have been required to provide financial support apart from their scheduled lease payments. See Note 4 to the financial statements for details of the nuclear fuel companies’ credit facilities and commercial paper borrowings and long-term debt that are reported by Entergy, Entergy Arkansas, Entergy Louisiana, and System Energy. These amounts also represent Entergy’s and the respective Registrant Subsidiary’s maximum exposure to losses associated with their respective interests in the nuclear fuel companies. Entergy Texas Restoration Funding, LLC and Entergy Texas Restoration Funding II, LLC, companies wholly-owned and consolidated by Entergy Texas, are VIEs and Entergy Texas is the primary beneficiary. In November 2009, Entergy Texas Restoration Funding issued senior secured transition bonds (securitization bonds) to finance Entergy Texas’s Hurricane Ike and Hurricane Gustav restoration costs. Although the principal amount was not due until November 2023, Entergy Texas Restoration Funding made principal payments on the bonds in 2022, after which the bonds were fully repaid. In April 2022, Entergy Texas Restoration Funding II issued senior secured system restoration bonds (securitization bonds) to finance Entergy Texas’s Hurricane Laura, Hurricane Delta, and Winter Storm Uri restoration costs. With the proceeds, the VIEs purchased from Entergy Texas the transition property, which is the right to recover from customers through a system restoration charge amounts sufficient to service the securitization bonds. The transition property is reflected as a regulatory asset on the consolidated Entergy Texas balance sheet. The creditors of Entergy Texas do not have recourse to the assets or revenues of the VIEs, including the transition property, and the creditors of the VIEs do not have recourse to the assets or revenues of Entergy Texas. Entergy Texas has no payment obligations to the VIEs except to remit system restoration charge collections. See Note 5 to the financial statements for additional details regarding the securitization bonds. Entergy New Orleans Storm Recovery Funding I, L.L.C., a company wholly-owned and consolidated by Entergy New Orleans, is a VIE and Entergy New Orleans is the primary beneficiary. In July 2015, Entergy New Orleans Storm Recovery Funding issued storm cost recovery bonds to recover Entergy New Orleans’s Hurricane Isaac storm restoration costs, including carrying costs, the costs of funding and replenishing the storm recovery reserve, and up-front financing costs associated with the securitization. With the proceeds, Entergy New Orleans Storm Recovery Funding purchased from Entergy New Orleans the storm recovery property, which is the right to recover from customers through a storm recovery charge amounts sufficient to service the securitization bonds. Although the principal amount was not due until June 2027, Entergy New Orleans Storm Recovery Funding made a principal payment on the bonds in 2024, after which the bonds were fully repaid. See Note 5 to the financial statements for additional details regarding the securitization bonds. Restoration Law Trust I (the storm trust I), a trust consolidated by Entergy Louisiana, is a VIE and Entergy Louisiana is the primary beneficiary. The storm trust I was established as part of the May 2022 Act 293 securitization of Entergy Louisiana’s Hurricane Laura, Hurricane Delta, Hurricane Zeta, and Winter Storm Uri restoration costs, as well as to establish a storm reserve to fund a portion of Hurricane Ida storm restoration costs. Entergy Louisiana is the primary beneficiary of the storm trust I because it was created to facilitate the financing of Entergy Louisiana’s storm restoration costs and Entergy Louisiana is entitled to receive a majority of the proceeds received by the storm trust I. As of December 31, 2024 and 2023, the primary asset held by the storm trust I was $2.9 billion and $3.0 billion, respectively, of outstanding Entergy Finance Company preferred membership interests, which is reflected as an investment in affiliate preferred membership interests on the consolidated balance sheets of Entergy Louisiana. The storm trust I’s investment in affiliate preferred membership interests was purchased with the net bond proceeds of the securitization bonds issued by the LCDA. After the securitization bonds were issued, the LCDA loaned the net bond proceeds to the LURC, and pursuant to Act 293, the LURC contributed the net bond proceeds to the storm trust I. The holders of the securitization bonds do not have recourse to the assets or revenues of the trust or to any Entergy affiliate and the bonds are not reflected in the consolidated balance sheets of Entergy or Entergy Louisiana. The LURC’s 1% beneficial interest in the storm trust I is recorded as noncontrolling interest on the consolidated balance sheets of Entergy and Entergy Louisiana, with balances of $28.8 million and $30.5 million as of December 31, 2024 and 2023, respectively. See Note 2 to the financial statements for additional discussion of the securitization bonds and the preferred membership interests. Restoration Law Trust II (the storm trust II), a trust consolidated by Entergy Louisiana, is a VIE and Entergy Louisiana is the primary beneficiary. The storm trust II was established as part of the March 2023 Act 293 securitization of Entergy Louisiana’s Hurricane Ida restoration costs, less Hurricane Ida amounts previously financed in May 2022 in a prior securitization transaction. Entergy Louisiana is the primary beneficiary of the storm trust II because it was created to facilitate the financing of Entergy Louisiana’s storm restoration costs and Entergy Louisiana is entitled to receive a majority of the proceeds received by the storm trust II. As of December 31, 2024 and 2023, the primary asset held by the storm trust II was $1.4 billion and $1.5 billion, respectively, of outstanding Entergy Finance Company preferred membership interests, which is reflected as an investment in affiliate preferred membership interests on the consolidated balance sheets of Entergy Louisiana. The storm trust II’s investment in affiliate preferred membership interests was purchased with the net bond proceeds of the securitization bonds issued by the LCDA. After the securitization bonds were issued, the LCDA loaned the net bond proceeds to the LURC, and pursuant to Act 293, the LURC contributed the net bond proceeds to the storm trust II. The holders of the securitization bonds do not have recourse to the assets or revenues of the storm trust II or to any Entergy affiliate and the bonds are not reflected in the consolidated balance sheets of Entergy or Entergy Louisiana. The LURC’s 1% beneficial interest in the storm trust II is recorded as noncontrolling interest on the consolidated balance sheets of Entergy and Entergy Louisiana, with balances of $13.9 million and $14.6 million as of December 31, 2024 and 2023, respectively. See Note 2 to the financial statements for additional discussion of the securitization bonds and the preferred membership interests. System Energy is considered to hold a variable interest in the lessor from which it leases an undivided interest in the Grand Gulf nuclear plant. System Energy is the lessee under this arrangement, which is described in more detail in Note 5 to the financial statements. System Energy made payments under this arrangement, including interest, of $17.2 million in 2024, 2023, and 2022. The lessor is a bank acting in the capacity of owner trustee for the benefit of equity investors in the transaction pursuant to trust agreement entered solely for the purpose of facilitating the lease transaction. It is possible that System Energy may be considered as the primary beneficiary of the lessor, but it is unable to apply the authoritative accounting guidance with respect to this VIE because the lessor is not required to, and could not, provide the necessary financial information to consolidate the lessor. Because System Energy accounts for this leasing arrangement as a capital financing, however, System Energy believes that consolidating the lessor would not materially affect the financial statements. In the event of default under a lease, remedies available to the lessor include payment by the lessee of the fair value of the undivided interest in the plant, payment of the present value of the basic rent payments, or payment of a predetermined casualty value. System Energy believes, however, that the obligations recorded on the balance sheet materially represent its potential exposure to loss. AR Searcy Partnership, LLC, is a tax equity partnership that qualifies as a VIE, which Entergy Arkansas is required to consolidate as it is the primary beneficiary. AR Searcy Partnership, LLC, was formed to acquire and own the Searcy Solar facility. The entity is a VIE because the holders of the membership interests, as a group, lack the characteristics of a controlling financial interest, including substantive kick out rights. Entergy Arkansas is the primary beneficiary of the partnership because, as the managing member, it has the right to direct the operations and receive a majority of the operating income of the partnership. See Note 1 to the financial statements for discussion of the presentation of the third party tax equity partner’s noncontrolling interest and the HLBV method of accounting used to account for Entergy Arkansas’s investment in AR Searcy Partnership, LLC. As of December 31, 2024, AR Searcy Partnership, LLC recorded assets equal to $129.7 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Arkansas’s ownership interest in the partnership was approximately $113.2 million. As of December 31, 2023, AR Searcy Partnership, LLC recorded assets equal to $134 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Arkansas’s ownership interest in the partnership was approximately $111.2 million. The tax equity investor’s ownership interest is recorded as noncontrolling interest. MS Sunflower Partnership, LLC, is a tax equity partnership that qualifies as a VIE, which Entergy Mississippi is required to consolidate as it is the primary beneficiary. See Note 14 to the financial statements for additional discussion on the establishment of MS Sunflower Partnership, LLC and the acquisition of the Sunflower Solar facility. The entity is a VIE because the holders of the membership interests, as a group, lack the characteristics of a controlling financial interest, including substantive kick out rights. Entergy Mississippi is the primary beneficiary of the partnership because, as the managing member, it has the right to direct the operations and receive a majority of the operating income of the partnership. See Note 1 to the financial statements for discussion of the presentation of the third party tax equity partner’s noncontrolling interest and the HLBV method of accounting used to account for Entergy Mississippi’s investment in MS Sunflower Partnership, LLC. As of December 31, 2024, MS Sunflower Partnership, LLC recorded assets equal to $157.8 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Mississippi’s ownership interest in the partnership was approximately $132.7 million. As of December 31, 2023, MS Sunflower Partnership, LLC recorded assets equal to $163.2 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Mississippi’s ownership interest in the partnership was approximately $128.4 million. The tax equity investor’s ownership interest is recorded as noncontrolling interest. Entergy has also reviewed various lease arrangements, power purchase agreements, including agreements for renewable power, and other agreements that represent variable interests in other legal entities which have been determined to be VIEs. In these cases, Entergy has determined that it is not the primary beneficiary of the related VIE because it does not have the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, or it does not have the obligation to absorb losses or the right to residual returns that would potentially be significant to the entity, or both.

As of December 31, 2023, MS Sunflower Partnership, LLC recorded assets equal to $163.2 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Mississippi’s ownership interest in the partnership was approximately $128.4 million. The tax equity investor’s ownership interest is recorded as noncontrolling interest. Entergy has also reviewed various lease arrangements, power purchase agreements, including agreements for renewable power, and other agreements that represent variable interests in other legal entities which have been determined to be VIEs. In these cases, Entergy has determined that it is not the primary beneficiary of the related VIE because it does not have the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, or it does not have the obligation to absorb losses or the right to residual returns that would potentially be significant to the entity, or both.

Variable Interest Entity Disclosure [Text Block]	VARIABLE INTEREST ENTITIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Under applicable authoritative accounting guidance, a variable interest entity (VIE) is an entity that conducts a business or holds property that possesses any of the following characteristics: an insufficient amount of equity at risk to finance its activities, equity owners who do not have the power to direct the significant activities of the entity (or have voting rights that are disproportionate to their ownership interest), or where equity holders do not receive expected losses or returns. An entity may have an interest in a VIE through ownership or other contractual rights or obligations, and is required to consolidate a VIE if it is the VIE’s primary beneficiary. The primary beneficiary of a VIE is the entity that has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and has the obligation to absorb losses or has the right to residual returns that would potentially be significant to the entity. Entergy Arkansas, Entergy Louisiana, and System Energy consolidate the respective companies from which they lease nuclear fuel, usually in a sale and leaseback transaction. This is because Entergy directs the nuclear fuel companies with respect to nuclear fuel purchases, assists the nuclear fuel companies in obtaining financing, and, if financing cannot be arranged, the lessee (Entergy Arkansas, Entergy Louisiana, or System Energy) is required to pay advance rent (Entergy Arkansas VIE, Entergy Louisiana Waterford VIE, and System Energy VIE) or special payments (Entergy Louisiana River Bend VIE) to allow the nuclear fuel company (the VIE) to meet its obligations. During the term of the arrangements, none of the Entergy operating companies have been required to provide financial support apart from their scheduled lease payments. See Note 4 to the financial statements for details of the nuclear fuel companies’ credit facilities and commercial paper borrowings and long-term debt that are reported by Entergy, Entergy Arkansas, Entergy Louisiana, and System Energy. These amounts also represent Entergy’s and the respective Registrant Subsidiary’s maximum exposure to losses associated with their respective interests in the nuclear fuel companies. Entergy Texas Restoration Funding, LLC and Entergy Texas Restoration Funding II, LLC, companies wholly-owned and consolidated by Entergy Texas, are VIEs and Entergy Texas is the primary beneficiary. In November 2009, Entergy Texas Restoration Funding issued senior secured transition bonds (securitization bonds) to finance Entergy Texas’s Hurricane Ike and Hurricane Gustav restoration costs. Although the principal amount was not due until November 2023, Entergy Texas Restoration Funding made principal payments on the bonds in 2022, after which the bonds were fully repaid. In April 2022, Entergy Texas Restoration Funding II issued senior secured system restoration bonds (securitization bonds) to finance Entergy Texas’s Hurricane Laura, Hurricane Delta, and Winter Storm Uri restoration costs. With the proceeds, the VIEs purchased from Entergy Texas the transition property, which is the right to recover from customers through a system restoration charge amounts sufficient to service the securitization bonds. The transition property is reflected as a regulatory asset on the consolidated Entergy Texas balance sheet. The creditors of Entergy Texas do not have recourse to the assets or revenues of the VIEs, including the transition property, and the creditors of the VIEs do not have recourse to the assets or revenues of Entergy Texas. Entergy Texas has no payment obligations to the VIEs except to remit system restoration charge collections. See Note 5 to the financial statements for additional details regarding the securitization bonds. Entergy New Orleans Storm Recovery Funding I, L.L.C., a company wholly-owned and consolidated by Entergy New Orleans, is a VIE and Entergy New Orleans is the primary beneficiary. In July 2015, Entergy New Orleans Storm Recovery Funding issued storm cost recovery bonds to recover Entergy New Orleans’s Hurricane Isaac storm restoration costs, including carrying costs, the costs of funding and replenishing the storm recovery reserve, and up-front financing costs associated with the securitization. With the proceeds, Entergy New Orleans Storm Recovery Funding purchased from Entergy New Orleans the storm recovery property, which is the right to recover from customers through a storm recovery charge amounts sufficient to service the securitization bonds. Although the principal amount was not due until June 2027, Entergy New Orleans Storm Recovery Funding made a principal payment on the bonds in 2024, after which the bonds were fully repaid. See Note 5 to the financial statements for additional details regarding the securitization bonds. Restoration Law Trust I (the storm trust I), a trust consolidated by Entergy Louisiana, is a VIE and Entergy Louisiana is the primary beneficiary. The storm trust I was established as part of the May 2022 Act 293 securitization of Entergy Louisiana’s Hurricane Laura, Hurricane Delta, Hurricane Zeta, and Winter Storm Uri restoration costs, as well as to establish a storm reserve to fund a portion of Hurricane Ida storm restoration costs. Entergy Louisiana is the primary beneficiary of the storm trust I because it was created to facilitate the financing of Entergy Louisiana’s storm restoration costs and Entergy Louisiana is entitled to receive a majority of the proceeds received by the storm trust I. As of December 31, 2024 and 2023, the primary asset held by the storm trust I was $2.9 billion and $3.0 billion, respectively, of outstanding Entergy Finance Company preferred membership interests, which is reflected as an investment in affiliate preferred membership interests on the consolidated balance sheets of Entergy Louisiana. The storm trust I’s investment in affiliate preferred membership interests was purchased with the net bond proceeds of the securitization bonds issued by the LCDA. After the securitization bonds were issued, the LCDA loaned the net bond proceeds to the LURC, and pursuant to Act 293, the LURC contributed the net bond proceeds to the storm trust I. The holders of the securitization bonds do not have recourse to the assets or revenues of the trust or to any Entergy affiliate and the bonds are not reflected in the consolidated balance sheets of Entergy or Entergy Louisiana. The LURC’s 1% beneficial interest in the storm trust I is recorded as noncontrolling interest on the consolidated balance sheets of Entergy and Entergy Louisiana, with balances of $28.8 million and $30.5 million as of December 31, 2024 and 2023, respectively. See Note 2 to the financial statements for additional discussion of the securitization bonds and the preferred membership interests. Restoration Law Trust II (the storm trust II), a trust consolidated by Entergy Louisiana, is a VIE and Entergy Louisiana is the primary beneficiary. The storm trust II was established as part of the March 2023 Act 293 securitization of Entergy Louisiana’s Hurricane Ida restoration costs, less Hurricane Ida amounts previously financed in May 2022 in a prior securitization transaction. Entergy Louisiana is the primary beneficiary of the storm trust II because it was created to facilitate the financing of Entergy Louisiana’s storm restoration costs and Entergy Louisiana is entitled to receive a majority of the proceeds received by the storm trust II. As of December 31, 2024 and 2023, the primary asset held by the storm trust II was $1.4 billion and $1.5 billion, respectively, of outstanding Entergy Finance Company preferred membership interests, which is reflected as an investment in affiliate preferred membership interests on the consolidated balance sheets of Entergy Louisiana. The storm trust II’s investment in affiliate preferred membership interests was purchased with the net bond proceeds of the securitization bonds issued by the LCDA.

The holders of the securitization bonds do not have recourse to the assets or revenues of the storm trust II or to any Entergy affiliate and the bonds are not reflected in the consolidated balance sheets of Entergy or Entergy Louisiana. The LURC’s 1% beneficial interest in the storm trust II is recorded as noncontrolling interest on the consolidated balance sheets of Entergy and Entergy Louisiana, with balances of $13.9 million and $14.6 million as of December 31, 2024 and 2023, respectively. See Note 2 to the financial statements for additional discussion of the securitization bonds and the preferred membership interests. System Energy is considered to hold a variable interest in the lessor from which it leases an undivided interest in the Grand Gulf nuclear plant. System Energy is the lessee under this arrangement, which is described in more detail in Note 5 to the financial statements. System Energy made payments under this arrangement, including interest, of $17.2 million in 2024, 2023, and 2022. The lessor is a bank acting in the capacity of owner trustee for the benefit of equity investors in the transaction pursuant to trust agreement entered solely for the purpose of facilitating the lease transaction. It is possible that System Energy may be considered as the primary beneficiary of the lessor, but it is unable to apply the authoritative accounting guidance with respect to this VIE because the lessor is not required to, and could not, provide the necessary financial information to consolidate the lessor. Because System Energy accounts for this leasing arrangement as a capital financing, however, System Energy believes that consolidating the lessor would not materially affect the financial statements. In the event of default under a lease, remedies available to the lessor include payment by the lessee of the fair value of the undivided interest in the plant, payment of the present value of the basic rent payments, or payment of a predetermined casualty value. System Energy believes, however, that the obligations recorded on the balance sheet materially represent its potential exposure to loss. AR Searcy Partnership, LLC, is a tax equity partnership that qualifies as a VIE, which Entergy Arkansas is required to consolidate as it is the primary beneficiary. AR Searcy Partnership, LLC, was formed to acquire and own the Searcy Solar facility. The entity is a VIE because the holders of the membership interests, as a group, lack the characteristics of a controlling financial interest, including substantive kick out rights. Entergy Arkansas is the primary beneficiary of the partnership because, as the managing member, it has the right to direct the operations and receive a majority of the operating income of the partnership. See Note 1 to the financial statements for discussion of the presentation of the third party tax equity partner’s noncontrolling interest and the HLBV method of accounting used to account for Entergy Arkansas’s investment in AR Searcy Partnership, LLC. As of December 31, 2024, AR Searcy Partnership, LLC recorded assets equal to $129.7 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Arkansas’s ownership interest in the partnership was approximately $113.2 million. As of December 31, 2023, AR Searcy Partnership, LLC recorded assets equal to $134 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Arkansas’s ownership interest in the partnership was approximately $111.2 million. The tax equity investor’s ownership interest is recorded as noncontrolling interest.

The LURC’s 1% beneficial interest in the storm trust II is recorded as noncontrolling interest on the consolidated balance sheets of Entergy and Entergy Louisiana, with balances of $13.9 million and $14.6 million as of December 31, 2024 and 2023, respectively. See Note 2 to the financial statements for additional discussion of the securitization bonds and the preferred membership interests. System Energy is considered to hold a variable interest in the lessor from which it leases an undivided interest in the Grand Gulf nuclear plant. System Energy is the lessee under this arrangement, which is described in more detail in Note 5 to the financial statements. System Energy made payments under this arrangement, including interest, of $17.2 million in 2024, 2023, and 2022. The lessor is a bank acting in the capacity of owner trustee for the benefit of equity investors in the transaction pursuant to trust agreement entered solely for the purpose of facilitating the lease transaction. It is possible that System Energy may be considered as the primary beneficiary of the lessor, but it is unable to apply the authoritative accounting guidance with respect to this VIE because the lessor is not required to, and could not, provide the necessary financial information to consolidate the lessor. Because System Energy accounts for this leasing arrangement as a capital financing, however, System Energy believes that consolidating the lessor would not materially affect the financial statements. In the event of default under a lease, remedies available to the lessor include payment by the lessee of the fair value of the undivided interest in the plant, payment of the present value of the basic rent payments, or payment of a predetermined casualty value. System Energy believes, however, that the obligations recorded on the balance sheet materially represent its potential exposure to loss. AR Searcy Partnership, LLC, is a tax equity partnership that qualifies as a VIE, which Entergy Arkansas is required to consolidate as it is the primary beneficiary. AR Searcy Partnership, LLC, was formed to acquire and own the Searcy Solar facility. The entity is a VIE because the holders of the membership interests, as a group, lack the characteristics of a controlling financial interest, including substantive kick out rights. Entergy Arkansas is the primary beneficiary of the partnership because, as the managing member, it has the right to direct the operations and receive a majority of the operating income of the partnership. See Note 1 to the financial statements for discussion of the presentation of the third party tax equity partner’s noncontrolling interest and the HLBV method of accounting used to account for Entergy Arkansas’s investment in AR Searcy Partnership, LLC. As of December 31, 2024, AR Searcy Partnership, LLC recorded assets equal to $129.7 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Arkansas’s ownership interest in the partnership was approximately $113.2 million. As of December 31, 2023, AR Searcy Partnership, LLC recorded assets equal to $134 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Arkansas’s ownership interest in the partnership was approximately $111.2 million. The tax equity investor’s ownership interest is recorded as noncontrolling interest. MS Sunflower Partnership, LLC, is a tax equity partnership that qualifies as a VIE, which Entergy Mississippi is required to consolidate as it is the primary beneficiary. See Note 14 to the financial statements for additional discussion on the establishment of MS Sunflower Partnership, LLC and the acquisition of the Sunflower Solar facility. The entity is a VIE because the holders of the membership interests, as a group, lack the characteristics of a controlling financial interest, including substantive kick out rights. Entergy Mississippi is the primary beneficiary of the partnership because, as the managing member, it has the right to direct the operations and receive a majority of the operating income of the partnership. See Note 1 to the financial statements for discussion of the presentation of the third party tax equity partner’s noncontrolling interest and the HLBV method of accounting used to account for Entergy Mississippi’s investment in MS Sunflower Partnership, LLC. As of December 31, 2024, MS Sunflower Partnership, LLC recorded assets equal to $157.8 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Mississippi’s ownership interest in the partnership was approximately $132.7 million. As of December 31, 2023, MS Sunflower Partnership, LLC recorded assets equal to $163.2 million, primarily consisting of property, plant, and equipment, and the carrying value of Entergy Mississippi’s ownership interest in the partnership was approximately $128.4 million. The tax equity investor’s ownership interest is recorded as noncontrolling interest. Entergy has also reviewed various lease arrangements, power purchase agreements, including agreements for renewable power, and other agreements that represent variable interests in other legal entities which have been determined to be VIEs. In these cases, Entergy has determined that it is not the primary beneficiary of the related VIE because it does not have the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, or it does not have the obligation to absorb losses or the right to residual returns that would potentially be significant to the entity, or both.

Variable Interest Entity Disclosure [Text Block]	VARIABLE INTEREST ENTITIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Under applicable authoritative accounting guidance, a variable interest entity (VIE) is an entity that conducts a business or holds property that possesses any of the following characteristics: an insufficient amount of equity at risk to finance its activities, equity owners who do not have the power to direct the significant activities of the entity (or have voting rights that are disproportionate to their ownership interest), or where equity holders do not receive expected losses or returns. An entity may have an interest in a VIE through ownership or other contractual rights or obligations, and is required to consolidate a VIE if it is the VIE’s primary beneficiary. The primary beneficiary of a VIE is the entity that has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and has the obligation to absorb losses or has the right to residual returns that would potentially be significant to the entity. Entergy Arkansas, Entergy Louisiana, and System Energy consolidate the respective companies from which they lease nuclear fuel, usually in a sale and leaseback transaction. This is because Entergy directs the nuclear fuel companies with respect to nuclear fuel purchases, assists the nuclear fuel companies in obtaining financing, and, if financing cannot be arranged, the lessee (Entergy Arkansas, Entergy Louisiana, or System Energy) is required to pay advance rent (Entergy Arkansas VIE, Entergy Louisiana Waterford VIE, and System Energy VIE) or special payments (Entergy Louisiana River Bend VIE) to allow the nuclear fuel company (the VIE) to meet its obligations. During the term of the arrangements, none of the Entergy operating companies have been required to provide financial support apart from their scheduled lease payments. See Note 4 to the financial statements for details of the nuclear fuel companies’ credit facilities and commercial paper borrowings and long-term debt that are reported by Entergy, Entergy Arkansas, Entergy Louisiana, and System Energy. These amounts also represent Entergy’s and the respective Registrant Subsidiary’s maximum exposure to losses associated with their respective interests in the nuclear fuel companies. Entergy Texas Restoration Funding, LLC and Entergy Texas Restoration Funding II, LLC, companies wholly-owned and consolidated by Entergy Texas, are VIEs and Entergy Texas is the primary beneficiary. In November 2009, Entergy Texas Restoration Funding issued senior secured transition bonds (securitization bonds) to finance Entergy Texas’s Hurricane Ike and Hurricane Gustav restoration costs. Although the principal amount was not due until November 2023, Entergy Texas Restoration Funding made principal payments on the bonds in 2022, after which the bonds were fully repaid. In April 2022, Entergy Texas Restoration Funding II issued senior secured system restoration bonds (securitization bonds) to finance Entergy Texas’s Hurricane Laura, Hurricane Delta, and Winter Storm Uri restoration costs. With the proceeds, the VIEs purchased from Entergy Texas the transition property, which is the right to recover from customers through a system restoration charge amounts sufficient to service the securitization bonds. The transition property is reflected as a regulatory asset on the consolidated Entergy Texas balance sheet. The creditors of Entergy Texas do not have recourse to the assets or revenues of the VIEs, including the transition property, and the creditors of the VIEs do not have recourse to the assets or revenues of Entergy Texas. Entergy Texas has no payment obligations to the VIEs except to remit system restoration charge collections. See Note 5 to the financial statements for additional details regarding the securitization bonds. Entergy New Orleans Storm Recovery Funding I, L.L.C., a company wholly-owned and consolidated by Entergy New Orleans, is a VIE and Entergy New Orleans is the primary beneficiary. In July 2015, Entergy New Orleans Storm Recovery Funding issued storm cost recovery bonds to recover Entergy New Orleans’s Hurricane Isaac storm restoration costs, including carrying costs, the costs of funding and replenishing the storm recovery reserve, and up-front financing costs associated with the securitization. With the proceeds, Entergy New Orleans Storm Recovery Funding purchased from Entergy New Orleans the storm recovery property, which is the right to recover from customers through a storm recovery charge amounts sufficient to service the securitization bonds. Although the principal amount was not due until June 2027, Entergy New Orleans Storm Recovery Funding made a principal payment on the bonds in 2024, after which the bonds were fully repaid. See Note 5 to the financial statements for additional details regarding the securitization bonds. Restoration Law Trust I (the storm trust I), a trust consolidated by Entergy Louisiana, is a VIE and Entergy Louisiana is the primary beneficiary. The storm trust I was established as part of the May 2022 Act 293 securitization of Entergy Louisiana’s Hurricane Laura, Hurricane Delta, Hurricane Zeta, and Winter Storm Uri restoration costs, as well as to establish a storm reserve to fund a portion of Hurricane Ida storm restoration costs. Entergy Louisiana is the primary beneficiary of the storm trust I because it was created to facilitate the financing of Entergy Louisiana’s storm restoration costs and Entergy Louisiana is entitled to receive a majority of the proceeds received by the storm trust I. As of December 31, 2024 and 2023, the primary asset held by the storm trust I was $2.9 billion and $3.0 billion, respectively, of outstanding Entergy Finance Company preferred membership interests, which is reflected as an investment in affiliate preferred membership interests on the consolidated balance sheets of Entergy Louisiana. The storm trust I’s investment in affiliate preferred membership interests was purchased with the net bond proceeds of the securitization bonds issued by the LCDA. After the securitization bonds were issued, the LCDA loaned the net bond proceeds to the LURC, and pursuant to Act 293, the LURC contributed the net bond proceeds to the storm trust I. The holders of the securitization bonds do not have recourse to the assets or revenues of the trust or to any Entergy affiliate and the bonds are not reflected in the consolidated balance sheets of Entergy or Entergy Louisiana.

Entergy Louisiana is the primary beneficiary of the storm trust II because it was created to facilitate the financing of Entergy Louisiana’s storm restoration costs and Entergy Louisiana is entitled to receive a majority of the proceeds received by the storm trust II. As of December 31, 2024 and 2023, the primary asset held by the storm trust II was $1.4 billion and $1.5 billion, respectively, of outstanding Entergy Finance Company preferred membership interests, which is reflected as an investment in affiliate preferred membership interests on the consolidated balance sheets of Entergy Louisiana. The storm trust II’s investment in affiliate preferred membership interests was purchased with the net bond proceeds of the securitization bonds issued by the LCDA. After the securitization bonds were issued, the LCDA loaned the net bond proceeds to the LURC, and pursuant to Act 293, the LURC contributed the net bond proceeds to the storm trust II.

These sales represent financially binding commitments for the sale of physical energy the next day. These sales are adjusted to actual power generated and delivered in the real time market. Given the short duration of these transactions, Entergy does not consider them to be derivatives subject to fair value adjustments and includes them as part of customer revenues. (b) Other electric revenues consist primarily of transmission and ancillary services provided to participants of an ISO-administered market, unbilled revenue, and certain customer credits as directed by regulators. (c) Other Utility revenues include the equity component of carrying costs related to securitization, occasional sales of inventory, alternative revenue programs, provisions for revenue subject to refund, and late fees. (d) Other revenues include the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, and amortization of a below-market power purchase agreement. Electric Revenues Entergy’s primary source of revenue is from retail electric sales sold under tariff rates approved by regulators in its various jurisdictions. Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas generate, transmit, and distribute electric power primarily to retail customers in Arkansas, Louisiana, Mississippi, and Texas. Entergy’s Utility operating companies provide power to customers on demand throughout the month, measured by a meter located at the customer’s property. Approved rates vary by customer class due to differing requirements of the customers and market factors involved in fulfilling those requirements. Entergy issues monthly bills to customers at rates approved by regulators for power and related services provided during the previous billing cycle. To the extent that deliveries have occurred, but a bill has not been issued, Entergy’s Utility operating companies record an estimate for energy delivered since the latest billings. The Utility operating companies calculate the estimate based upon several factors including actual metered customer usage, billings through the last billing cycle in a month, actual generation in the month, historical line loss factors, and market prices of power in the respective jurisdiction. The inputs are revised as needed to approximate actual usage and cost. Each month, estimated unbilled amounts are recorded as unbilled revenue and accounts receivable, and the prior month’s estimate is reversed. Price and volume differences resulting from factors such as weather affect the calculation of unbilled revenues from one period to the other. Entergy may record revenue based on rates that are subject to refund. Such revenues are reduced by estimated refund amounts when Entergy believes refunds are probable based on the status of rate proceedings as of the date financial statements are prepared. Because these refunds will be made through a reduction in future rates, and not as a reduction in bills previously issued, they are presented as other revenues in the table above. System Energy’s only source of revenue is the sale of electric power and capacity generated from its 90% interest in the Grand Gulf nuclear plant to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. System Energy issues monthly bills to its affiliated customers equal to its actual operating costs plus a return on common equity approved by the FERC . Effective January 1, 2025, Entergy Louisiana has divested all of its 14% share of capacity and energy from Grand Gulf and all of the capacity and energy from Grand Gulf that it purchases from Entergy Arkansas (approximately 2.43%) to Entergy Mississippi. This divestiture is being effectuated initially under a designated PPA between Entergy Louisiana and Entergy Mississippi, which was accepted by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025 . See Note 8 to the financial statements for further discussion of System Energy and the Unit Power Sales Agreement. Entergy’s Utility operating companies also sell excess power not needed for their own customers, primarily through transactions with MISO, a regional transmission organization that maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. In the MISO market, Entergy offers its generation and bids its load into the market. MISO settles these offers and bids based on locational marginal prices. These represent pricing for energy at a given location based on a market clearing price that takes into account physical limitations on the transmission system, generation, and demand throughout the MISO region. MISO evaluates each market participant’s energy offers and demand bids to economically and reliably dispatch the entire MISO system. Entergy nets purchases and sales within the MISO market and reports in operating revenues when in a net selling position and in operating expenses when in a net purchasing position. Natural Gas Entergy Louisiana and Entergy New Orleans also distribute natural gas to retail customers in and around Baton Rouge, Louisiana, and New Orleans, Louisiana, respectively. Gas transferred to customers is measured by a meter at the customer’s property. Entergy issues monthly invoices to customers at rates approved by regulators for the volume of gas transferred to date. See “ Held for Sale - Natural Gas Distribution Businesses ” in Note 14 to the financial statements for discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses. Other Revenues Entergy’s revenues from its non-utility operations i nclude the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, an d amortization of a below-market PPA. Practical Expedients and Exceptions Entergy has elected not to disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less, or for revenue recognized in an amount equal to what Entergy has the right to bill the customer for services performed. Most of Entergy’s contracts, except in a few cases where there are defined minimums or stated terms, are on demand. This results in customer bills that vary each month based on an approved tariff and usage. Entergy imposes monthly or annual minimum requirements on some customers primarily as credit and cost recovery guarantees and not as pricing for unsatisfied performance obligations. These minimums typically expire after the initial term or when specified costs have been recovered. The minimum amounts are part of each month’s bill and recognized as revenue accor dingly. Some Entergy subsidiaries in the non-utility operations business have services contracts that have fixed components and terms longer than one year. T he total fixed consideration related to these unsatisfied performance obligations, however, is not material to Entergy revenues. Recovery of Fuel Costs Entergy’s Utility operating companies’ rate schedules include either fuel adjustment clauses or fixed fuel factors, which allow either current recovery in billings to customers or deferral of fuel costs until the costs are billed to customers. Where the fuel component of revenues is based on a pre-determined fuel cost (fixed fuel factor), the fuel factor remains in effect until changed as part of a general rate case, fuel reconciliation, or fixed fuel factor filing. System Energy’s operating revenues are intended to recover from Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans operating expenses and capital costs attributable to Grand Gulf. The capital costs are based on System Energy’s common equity funds allocable to its net investment in Grand Gulf, plus System Energy’s effective interest cost for its debt allocable to its investment in Grand Gulf. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. Due to the essential nature of utility services, Entergy has historically experienced a low rate of default on its accounts receivables. The following table sets forth a reconciliation of changes in the allowance for doubtful accounts for the years ended December 31, 2024 and 2023.

These sales represent financially binding commitments for the sale of physical energy the next day. These sales are adjusted to actual power generated and delivered in the real time market. Given the short duration of these transactions, Entergy does not consider them to be derivatives subject to fair value adjustments and includes them as part of customer revenues. (b) Other electric revenues consist primarily of transmission and ancillary services provided to participants of an ISO-administered market, unbilled revenue, and certain customer credits as directed by regulators. (c) Other Utility revenues include the equity component of carrying costs related to securitization, occasional sales of inventory, alternative revenue programs, provisions for revenue subject to refund, and late fees. (d) Other revenues include the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, and amortization of a below-market power purchase agreement. Electric Revenues Entergy’s primary source of revenue is from retail electric sales sold under tariff rates approved by regulators in its various jurisdictions. Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas generate, transmit, and distribute electric power primarily to retail customers in Arkansas, Louisiana, Mississippi, and Texas. Entergy’s Utility operating companies provide power to customers on demand throughout the month, measured by a meter located at the customer’s property. Approved rates vary by customer class due to differing requirements of the customers and market factors involved in fulfilling those requirements. Entergy issues monthly bills to customers at rates approved by regulators for power and related services provided during the previous billing cycle. To the extent that deliveries have occurred, but a bill has not been issued, Entergy’s Utility operating companies record an estimate for energy delivered since the latest billings. The Utility operating companies calculate the estimate based upon several factors including actual metered customer usage, billings through the last billing cycle in a month, actual generation in the month, historical line loss factors, and market prices of power in the respective jurisdiction. The inputs are revised as needed to approximate actual usage and cost. Each month, estimated unbilled amounts are recorded as unbilled revenue and accounts receivable, and the prior month’s estimate is reversed. Price and volume differences resulting from factors such as weather affect the calculation of unbilled revenues from one period to the other. Entergy may record revenue based on rates that are subject to refund. Such revenues are reduced by estimated refund amounts when Entergy believes refunds are probable based on the status of rate proceedings as of the date financial statements are prepared. Because these refunds will be made through a reduction in future rates, and not as a reduction in bills previously issued, they are presented as other revenues in the table above. System Energy’s only source of revenue is the sale of electric power and capacity generated from its 90% interest in the Grand Gulf nuclear plant to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. System Energy issues monthly bills to its affiliated customers equal to its actual operating costs plus a return on common equity approved by the FERC . Effective January 1, 2025, Entergy Louisiana has divested all of its 14% share of capacity and energy from Grand Gulf and all of the capacity and energy from Grand Gulf that it purchases from Entergy Arkansas (approximately 2.43%) to Entergy Mississippi. This divestiture is being effectuated initially under a designated PPA between Entergy Louisiana and Entergy Mississippi, which was accepted by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025 . See Note 8 to the financial statements for further discussion of System Energy and the Unit Power Sales Agreement. Entergy’s Utility operating companies also sell excess power not needed for their own customers, primarily through transactions with MISO, a regional transmission organization that maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. In the MISO market, Entergy offers its generation and bids its load into the market. MISO settles these offers and bids based on locational marginal prices. These represent pricing for energy at a given location based on a market clearing price that takes into account physical limitations on the transmission system, generation, and demand throughout the MISO region. MISO evaluates each market participant’s energy offers and demand bids to economically and reliably dispatch the entire MISO system. Entergy nets purchases and sales within the MISO market and reports in operating revenues when in a net selling position and in operating expenses when in a net purchasing position. Natural Gas Entergy Louisiana and Entergy New Orleans also distribute natural gas to retail customers in and around Baton Rouge, Louisiana, and New Orleans, Louisiana, respectively. Gas transferred to customers is measured by a meter at the customer’s property. Entergy issues monthly invoices to customers at rates approved by regulators for the volume of gas transferred to date. See “ Held for Sale - Natural Gas Distribution Businesses ” in Note 14 to the financial statements for discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses. Other Revenues Entergy’s revenues from its non-utility operations i nclude the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, an d amortization of a below-market PPA. Practical Expedients and Exceptions Entergy has elected not to disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less, or for revenue recognized in an amount equal to what Entergy has the right to bill the customer for services performed. Most of Entergy’s contracts, except in a few cases where there are defined minimums or stated terms, are on demand. This results in customer bills that vary each month based on an approved tariff and usage. Entergy imposes monthly or annual minimum requirements on some customers primarily as credit and cost recovery guarantees and not as pricing for unsatisfied performance obligations. These minimums typically expire after the initial term or when specified costs have been recovered. The minimum amounts are part of each month’s bill and recognized as revenue accor dingly. Some Entergy subsidiaries in the non-utility operations business have services contracts that have fixed components and terms longer than one year. T he total fixed consideration related to these unsatisfied performance obligations, however, is not material to Entergy revenues. Recovery of Fuel Costs Entergy’s Utility operating companies’ rate schedules include either fuel adjustment clauses or fixed fuel factors, which allow either current recovery in billings to customers or deferral of fuel costs until the costs are billed to customers. Where the fuel component of revenues is based on a pre-determined fuel cost (fixed fuel factor), the fuel factor remains in effect until changed as part of a general rate case, fuel reconciliation, or fixed fuel factor filing. System Energy’s operating revenues are intended to recover from Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans operating expenses and capital costs attributable to Grand Gulf. The capital costs are based on System Energy’s common equity funds allocable to its net investment in Grand Gulf, plus System Energy’s effective interest cost for its debt allocable to its investment in Grand Gulf. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. Due to the essential nature of utility services, Entergy has historically experienced a low rate of default on its accounts receivables. The following table sets forth a reconciliation of changes in the allowance for doubtful accounts for the years ended December 31, 2024 and 2023.

The rate of customer write-offs has historically experienced minimal variation, although general economic conditions can affect the rate of customer write-offs. Management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner.

Entergy’s Utility operating companies also sell excess power not needed for their own customers, primarily through transactions with MISO, a regional transmission organization that maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. In the MISO market, Entergy offers its generation and bids its load into the market. MISO settles these offers and bids based on locational marginal prices. These represent pricing for energy at a given location based on a market clearing price that takes into account physical limitations on the transmission system, generation, and demand throughout the MISO region. MISO evaluates each market participant’s energy offers and demand bids to economically and reliably dispatch the entire MISO system. Entergy nets purchases and sales within the MISO market and reports in operating revenues when in a net selling position and in operating expenses when in a net purchasing position. Natural Gas Entergy Louisiana and Entergy New Orleans also distribute natural gas to retail customers in and around Baton Rouge, Louisiana, and New Orleans, Louisiana, respectively. Gas transferred to customers is measured by a meter at the customer’s property. Entergy issues monthly invoices to customers at rates approved by regulators for the volume of gas transferred to date. See “ Held for Sale - Natural Gas Distribution Businesses ” in Note 14 to the financial statements for discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses. Other Revenues Entergy’s revenues from its non-utility operations i nclude the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, an d amortization of a below-market PPA. Practical Expedients and Exceptions Entergy has elected not to disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less, or for revenue recognized in an amount equal to what Entergy has the right to bill the customer for services performed. Most of Entergy’s contracts, except in a few cases where there are defined minimums or stated terms, are on demand. This results in customer bills that vary each month based on an approved tariff and usage. Entergy imposes monthly or annual minimum requirements on some customers primarily as credit and cost recovery guarantees and not as pricing for unsatisfied performance obligations. These minimums typically expire after the initial term or when specified costs have been recovered. The minimum amounts are part of each month’s bill and recognized as revenue accor dingly. Some Entergy subsidiaries in the non-utility operations business have services contracts that have fixed components and terms longer than one year. T he total fixed consideration related to these unsatisfied performance obligations, however, is not material to Entergy revenues. Recovery of Fuel Costs Entergy’s Utility operating companies’ rate schedules include either fuel adjustment clauses or fixed fuel factors, which allow either current recovery in billings to customers or deferral of fuel costs until the costs are billed to customers. Where the fuel component of revenues is based on a pre-determined fuel cost (fixed fuel factor), the fuel factor remains in effect until changed as part of a general rate case, fuel reconciliation, or fixed fuel factor filing. System Energy’s operating revenues are intended to recover from Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans operating expenses and capital costs attributable to Grand Gulf. The capital costs are based on System Energy’s common equity funds allocable to its net investment in Grand Gulf, plus System Energy’s effective interest cost for its debt allocable to its investment in Grand Gulf. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. Due to the essential nature of utility services, Entergy has historically experienced a low rate of default on its accounts receivables. The following table sets forth a reconciliation of changes in the allowance for doubtful accounts for the years ended December 31, 2024 and 2023.

The rate of customer write-offs has historically experienced minimal variation, although general economic conditions can affect the rate of customer write-offs. Management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner.

These sales represent financially binding commitments for the sale of physical energy the next day. These sales are adjusted to actual power generated and delivered in the real time market. Given the short duration of these transactions, Entergy does not consider them to be derivatives subject to fair value adjustments and includes them as part of customer revenues. (b) Other electric revenues consist primarily of transmission and ancillary services provided to participants of an ISO-administered market, unbilled revenue, and certain customer credits as directed by regulators. (c) Other Utility revenues include the equity component of carrying costs related to securitization, occasional sales of inventory, alternative revenue programs, provisions for revenue subject to refund, and late fees. (d) Other revenues include the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, and amortization of a below-market power purchase agreement. Electric Revenues Entergy’s primary source of revenue is from retail electric sales sold under tariff rates approved by regulators in its various jurisdictions. Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas generate, transmit, and distribute electric power primarily to retail customers in Arkansas, Louisiana, Mississippi, and Texas. Entergy’s Utility operating companies provide power to customers on demand throughout the month, measured by a meter located at the customer’s property. Approved rates vary by customer class due to differing requirements of the customers and market factors involved in fulfilling those requirements. Entergy issues monthly bills to customers at rates approved by regulators for power and related services provided during the previous billing cycle. To the extent that deliveries have occurred, but a bill has not been issued, Entergy’s Utility operating companies record an estimate for energy delivered since the latest billings. The Utility operating companies calculate the estimate based upon several factors including actual metered customer usage, billings through the last billing cycle in a month, actual generation in the month, historical line loss factors, and market prices of power in the respective jurisdiction. The inputs are revised as needed to approximate actual usage and cost. Each month, estimated unbilled amounts are recorded as unbilled revenue and accounts receivable, and the prior month’s estimate is reversed. Price and volume differences resulting from factors such as weather affect the calculation of unbilled revenues from one period to the other. Entergy may record revenue based on rates that are subject to refund. Such revenues are reduced by estimated refund amounts when Entergy believes refunds are probable based on the status of rate proceedings as of the date financial statements are prepared. Because these refunds will be made through a reduction in future rates, and not as a reduction in bills previously issued, they are presented as other revenues in the table above. System Energy’s only source of revenue is the sale of electric power and capacity generated from its 90% interest in the Grand Gulf nuclear plant to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. System Energy issues monthly bills to its affiliated customers equal to its actual operating costs plus a return on common equity approved by the FERC . Effective January 1, 2025, Entergy Louisiana has divested all of its 14% share of capacity and energy from Grand Gulf and all of the capacity and energy from Grand Gulf that it purchases from Entergy Arkansas (approximately 2.43%) to Entergy Mississippi. This divestiture is being effectuated initially under a designated PPA between Entergy Louisiana and Entergy Mississippi, which was accepted by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025 . See Note 8 to the financial statements for further discussion of System Energy and the Unit Power Sales Agreement. Entergy’s Utility operating companies also sell excess power not needed for their own customers, primarily through transactions with MISO, a regional transmission organization that maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. In the MISO market, Entergy offers its generation and bids its load into the market. MISO settles these offers and bids based on locational marginal prices. These represent pricing for energy at a given location based on a market clearing price that takes into account physical limitations on the transmission system, generation, and demand throughout the MISO region. MISO evaluates each market participant’s energy offers and demand bids to economically and reliably dispatch the entire MISO system. Entergy nets purchases and sales within the MISO market and reports in operating revenues when in a net selling position and in operating expenses when in a net purchasing position. Natural Gas Entergy Louisiana and Entergy New Orleans also distribute natural gas to retail customers in and around Baton Rouge, Louisiana, and New Orleans, Louisiana, respectively. Gas transferred to customers is measured by a meter at the customer’s property. Entergy issues monthly invoices to customers at rates approved by regulators for the volume of gas transferred to date.

Other Revenues Entergy’s revenues from its non-utility operations i nclude the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, an d amortization of a below-market PPA. Practical Expedients and Exceptions Entergy has elected not to disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less, or for revenue recognized in an amount equal to what Entergy has the right to bill the customer for services performed. Most of Entergy’s contracts, except in a few cases where there are defined minimums or stated terms, are on demand. This results in customer bills that vary each month based on an approved tariff and usage. Entergy imposes monthly or annual minimum requirements on some customers primarily as credit and cost recovery guarantees and not as pricing for unsatisfied performance obligations. These minimums typically expire after the initial term or when specified costs have been recovered. The minimum amounts are part of each month’s bill and recognized as revenue accor dingly. Some Entergy subsidiaries in the non-utility operations business have services contracts that have fixed components and terms longer than one year. T he total fixed consideration related to these unsatisfied performance obligations, however, is not material to Entergy revenues.

(b) Other electric revenues consist primarily of transmission and ancillary services provided to participants of an ISO-administered market, unbilled revenue, and certain customer credits as directed by regulators. (c) Other Utility revenues include the equity component of carrying costs related to securitization, occasional sales of inventory, alternative revenue programs, provisions for revenue subject to refund, and late fees. (d) Other revenues include the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, and amortization of a below-market power purchase agreement. Electric Revenues Entergy’s primary source of revenue is from retail electric sales sold under tariff rates approved by regulators in its various jurisdictions. Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas generate, transmit, and distribute electric power primarily to retail customers in Arkansas, Louisiana, Mississippi, and Texas. Entergy’s Utility operating companies provide power to customers on demand throughout the month, measured by a meter located at the customer’s property. Approved rates vary by customer class due to differing requirements of the customers and market factors involved in fulfilling those requirements. Entergy issues monthly bills to customers at rates approved by regulators for power and related services provided during the previous billing cycle. To the extent that deliveries have occurred, but a bill has not been issued, Entergy’s Utility operating companies record an estimate for energy delivered since the latest billings. The Utility operating companies calculate the estimate based upon several factors including actual metered customer usage, billings through the last billing cycle in a month, actual generation in the month, historical line loss factors, and market prices of power in the respective jurisdiction. The inputs are revised as needed to approximate actual usage and cost. Each month, estimated unbilled amounts are recorded as unbilled revenue and accounts receivable, and the prior month’s estimate is reversed. Price and volume differences resulting from factors such as weather affect the calculation of unbilled revenues from one period to the other. Entergy may record revenue based on rates that are subject to refund. Such revenues are reduced by estimated refund amounts when Entergy believes refunds are probable based on the status of rate proceedings as of the date financial statements are prepared. Because these refunds will be made through a reduction in future rates, and not as a reduction in bills previously issued, they are presented as other revenues in the table above. System Energy’s only source of revenue is the sale of electric power and capacity generated from its 90% interest in the Grand Gulf nuclear plant to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. System Energy issues monthly bills to its affiliated customers equal to its actual operating costs plus a return on common equity approved by the FERC . Effective January 1, 2025, Entergy Louisiana has divested all of its 14% share of capacity and energy from Grand Gulf and all of the capacity and energy from Grand Gulf that it purchases from Entergy Arkansas (approximately 2.43%) to Entergy Mississippi. This divestiture is being effectuated initially under a designated PPA between Entergy Louisiana and Entergy Mississippi, which was accepted by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025 . See Note 8 to the financial statements for further discussion of System Energy and the Unit Power Sales Agreement. Entergy’s Utility operating companies also sell excess power not needed for their own customers, primarily through transactions with MISO, a regional transmission organization that maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. In the MISO market, Entergy offers its generation and bids its load into the market. MISO settles these offers and bids based on locational marginal prices. These represent pricing for energy at a given location based on a market clearing price that takes into account physical limitations on the transmission system, generation, and demand throughout the MISO region. MISO evaluates each market participant’s energy offers and demand bids to economically and reliably dispatch the entire MISO system. Entergy nets purchases and sales within the MISO market and reports in operating revenues when in a net selling position and in operating expenses when in a net purchasing position. Natural Gas Entergy Louisiana and Entergy New Orleans also distribute natural gas to retail customers in and around Baton Rouge, Louisiana, and New Orleans, Louisiana, respectively. Gas transferred to customers is measured by a meter at the customer’s property. Entergy issues monthly invoices to customers at rates approved by regulators for the volume of gas transferred to date. See “ Held for Sale - Natural Gas Distribution Businesses ” in Note 14 to the financial statements for discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses. Other Revenues Entergy’s revenues from its non-utility operations i nclude the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, an d amortization of a below-market PPA. Practical Expedients and Exceptions Entergy has elected not to disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less, or for revenue recognized in an amount equal to what Entergy has the right to bill the customer for services performed. Most of Entergy’s contracts, except in a few cases where there are defined minimums or stated terms, are on demand. This results in customer bills that vary each month based on an approved tariff and usage. Entergy imposes monthly or annual minimum requirements on some customers primarily as credit and cost recovery guarantees and not as pricing for unsatisfied performance obligations. These minimums typically expire after the initial term or when specified costs have been recovered. The minimum amounts are part of each month’s bill and recognized as revenue accor dingly. Some Entergy subsidiaries in the non-utility operations business have services contracts that have fixed components and terms longer than one year. T he total fixed consideration related to these unsatisfied performance obligations, however, is not material to Entergy revenues. Recovery of Fuel Costs Entergy’s Utility operating companies’ rate schedules include either fuel adjustment clauses or fixed fuel factors, which allow either current recovery in billings to customers or deferral of fuel costs until the costs are billed to customers. Where the fuel component of revenues is based on a pre-determined fuel cost (fixed fuel factor), the fuel factor remains in effect until changed as part of a general rate case, fuel reconciliation, or fixed fuel factor filing. System Energy’s operating revenues are intended to recover from Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans operating expenses and capital costs attributable to Grand Gulf. The capital costs are based on System Energy’s common equity funds allocable to its net investment in Grand Gulf, plus System Energy’s effective interest cost for its debt allocable to its investment in Grand Gulf. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. Due to the essential nature of utility services, Entergy has historically experienced a low rate of default on its accounts receivables. The following table sets forth a reconciliation of changes in the allowance for doubtful accounts for the years ended December 31, 2024 and 2023. Entergy Entergy Entergy Entergy Entergy Entergy (In Millions) Balance as of December 31, 2022 $30.9 $6.5 $7.6 $2.5 $11.9 $2.4 Provisions 38.7 9.4 13.9 7.3 3.4 4.7 Write-offs (83.1) (20.6) (31.3) (10.4) (10.7) (10.1) Recoveries 39.4 11.9 15.9 3.9 3.2 4.5 Balance as of December 31, 2023 $25.9 $7.2 $6.1 $3.3 $7.8 $1.5 Provisions 32.0 7.0 10.0 4.8 4.6 5.6 Write-offs (71.2) (17.5) (23.3) (11.5) (10.4) (8.5) Recoveries 31.2 8.0 10.2 5.6 4.7 2.7 Balance as of December 31, 2024 $17.9 $4.7 $3.0 $2.2 $6.7 $1.3 The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. The rate of customer write-offs has historically experienced minimal variation, although general economic conditions can affect the rate of customer write-offs. Management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner.

These sales represent financially binding commitments for the sale of physical energy the next day. These sales are adjusted to actual power generated and delivered in the real time market. Given the short duration of these transactions, Entergy does not consider them to be derivatives subject to fair value adjustments and includes them as part of customer revenues. (b) Other electric revenues consist primarily of transmission and ancillary services provided to participants of an ISO-administered market, unbilled revenue, and certain customer credits as directed by regulators. (c) Other Utility revenues include the equity component of carrying costs related to securitization, occasional sales of inventory, alternative revenue programs, provisions for revenue subject to refund, and late fees. (d) Other revenues include the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, and amortization of a below-market power purchase agreement. Electric Revenues Entergy’s primary source of revenue is from retail electric sales sold under tariff rates approved by regulators in its various jurisdictions. Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas generate, transmit, and distribute electric power primarily to retail customers in Arkansas, Louisiana, Mississippi, and Texas. Entergy’s Utility operating companies provide power to customers on demand throughout the month, measured by a meter located at the customer’s property. Approved rates vary by customer class due to differing requirements of the customers and market factors involved in fulfilling those requirements. Entergy issues monthly bills to customers at rates approved by regulators for power and related services provided during the previous billing cycle. To the extent that deliveries have occurred, but a bill has not been issued, Entergy’s Utility operating companies record an estimate for energy delivered since the latest billings. The Utility operating companies calculate the estimate based upon several factors including actual metered customer usage, billings through the last billing cycle in a month, actual generation in the month, historical line loss factors, and market prices of power in the respective jurisdiction. The inputs are revised as needed to approximate actual usage and cost. Each month, estimated unbilled amounts are recorded as unbilled revenue and accounts receivable, and the prior month’s estimate is reversed. Price and volume differences resulting from factors such as weather affect the calculation of unbilled revenues from one period to the other. Entergy may record revenue based on rates that are subject to refund. Such revenues are reduced by estimated refund amounts when Entergy believes refunds are probable based on the status of rate proceedings as of the date financial statements are prepared. Because these refunds will be made through a reduction in future rates, and not as a reduction in bills previously issued, they are presented as other revenues in the table above. System Energy’s only source of revenue is the sale of electric power and capacity generated from its 90% interest in the Grand Gulf nuclear plant to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. System Energy issues monthly bills to its affiliated customers equal to its actual operating costs plus a return on common equity approved by the FERC . Effective January 1, 2025, Entergy Louisiana has divested all of its 14% share of capacity and energy from Grand Gulf and all of the capacity and energy from Grand Gulf that it purchases from Entergy Arkansas (approximately 2.43%) to Entergy Mississippi. This divestiture is being effectuated initially under a designated PPA between Entergy Louisiana and Entergy Mississippi, which was accepted by the FERC in November 2024. The MPSC approved the MSS-4 replacement PPA, effective as of January 1, 2025 . See Note 8 to the financial statements for further discussion of System Energy and the Unit Power Sales Agreement. Entergy’s Utility operating companies also sell excess power not needed for their own customers, primarily through transactions with MISO, a regional transmission organization that maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. In the MISO market, Entergy offers its generation and bids its load into the market. MISO settles these offers and bids based on locational marginal prices. These represent pricing for energy at a given location based on a market clearing price that takes into account physical limitations on the transmission system, generation, and demand throughout the MISO region. MISO evaluates each market participant’s energy offers and demand bids to economically and reliably dispatch the entire MISO system. Entergy nets purchases and sales within the MISO market and reports in operating revenues when in a net selling position and in operating expenses when in a net purchasing position. Natural Gas Entergy Louisiana and Entergy New Orleans also distribute natural gas to retail customers in and around Baton Rouge, Louisiana, and New Orleans, Louisiana, respectively. Gas transferred to customers is measured by a meter at the customer’s property. Entergy issues monthly invoices to customers at rates approved by regulators for the volume of gas transferred to date. See “ Held for Sale - Natural Gas Distribution Businesses ” in Note 14 to the financial statements for discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses. Other Revenues Entergy’s revenues from its non-utility operations i nclude the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, operation and management services fees, an d amortization of a below-market PPA. Practical Expedients and Exceptions Entergy has elected not to disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less, or for revenue recognized in an amount equal to what Entergy has the right to bill the customer for services performed. Most of Entergy’s contracts, except in a few cases where there are defined minimums or stated terms, are on demand. This results in customer bills that vary each month based on an approved tariff and usage. Entergy imposes monthly or annual minimum requirements on some customers primarily as credit and cost recovery guarantees and not as pricing for unsatisfied performance obligations. These minimums typically expire after the initial term or when specified costs have been recovered. The minimum amounts are part of each month’s bill and recognized as revenue accor dingly. Some Entergy subsidiaries in the non-utility operations business have services contracts that have fixed components and terms longer than one year. T he total fixed consideration related to these unsatisfied performance obligations, however, is not material to Entergy revenues. Recovery of Fuel Costs Entergy’s Utility operating companies’ rate schedules include either fuel adjustment clauses or fixed fuel factors, which allow either current recovery in billings to customers or deferral of fuel costs until the costs are billed to customers. Where the fuel component of revenues is based on a pre-determined fuel cost (fixed fuel factor), the fuel factor remains in effect until changed as part of a general rate case, fuel reconciliation, or fixed fuel factor filing. System Energy’s operating revenues are intended to recover from Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans operating expenses and capital costs attributable to Grand Gulf. The capital costs are based on System Energy’s common equity funds allocable to its net investment in Grand Gulf, plus System Energy’s effective interest cost for its debt allocable to its investment in Grand Gulf. Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. Due to the essential nature of utility services, Entergy has historically experienced a low rate of default on its accounts receivables. The following table sets forth a reconciliation of changes in the allowance for doubtful accounts for the years ended December 31, 2024 and 2023. Entergy Entergy Entergy Entergy Entergy Entergy (In Millions) Balance as of December 31, 2022 $30.9 $6.5 $7.6 $2.5 $11.9 $2.4 Provisions 38.7 9.4 13.9 7.3 3.4 4.7 Write-offs (83.1) (20.6) (31.3) (10.4) (10.7) (10.1) Recoveries 39.4 11.9 15.9 3.9 3.2 4.5 Balance as of December 31, 2023 $25.9 $7.2 $6.1 $3.3 $7.8 $1.5 Provisions 32.0 7.0 10.0 4.8 4.6 5.6 Write-offs (71.2) (17.5) (23.3) (11.5) (10.4) (8.5) Recoveries 31.2 8.0 10.2 5.6 4.7 2.7 Balance as of December 31, 2024 $17.9 $4.7 $3.0 $2.2 $6.7 $1.3 The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. The rate of customer write-offs has historically experienced minimal variation, although general economic conditions can affect the rate of customer write-offs. Management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner.

Award Timing MNPI Disclosure	Policies and Practices Related to the Timing of Grants of Certain Equity Awards The Talent and Compensation Committee and senior management monitor the Company’s equity grant practices to evaluate whether such policies comply with governing regulations and are consistent with good corporate practices. When making regular annual equity grants, including stock options, the Talent and Compensation Committee’s practice is to approve them at its meeting in late January or in the first week of February of each year, which is near the beginning of the Company’s fiscal year, as part of the annual compensation review. In addition, the Talent and Compensation Committee may make grants at other times during the year for new hires or for other reasons, including, for example, job promotions or for retention purposes. Because the Talent and Compensation Committee’s regular meeting schedule is generally determined in the prior fiscal year and, as noted above, the Company generally makes annual equity awards to our NEOs at approximately the same time each year, the proximity of any awards to other significant corporate events is coincidental. The Company does not time its equity awards to take advantage of the release of earnings or other major announcements by the Company or market conditions. During 2024, no stock option grants were made to any of our NEOs during any period beginning four business days before the filing or furnishing of a periodic report or current report and ending one business day after the filing or furnishing of any such report with the SEC.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Entergy and the Registrant Subsidiaries maintain a security-risk-management system with defined roles, duties, governance, and accountability. Under this physical- and cyber-risk model, Entergy and the Registrant Subsidiaries streamline security into a centralized program. The Chief Security Officer (CSO) is responsible for establishing the security and reliability risk strategy, setting policies, monitoring controls and compliance, providing support activities, and reporting on the security program. The Chief Information Security Officer (CISO) is responsible for establishing the cybersecurity strategy and implementing physical and cyber security systems for the security program. The Chief Information Officer (CIO) is responsible for ensuring that Entergy’s information technology infrastructure is secure and reliable. The Chief Ethics & Compliance Officer works with the CSO to address requirements of external security-related regulations, and where applicable, incorporate them into business policies. Management is responsible for identifying and managing risk directly through execution of the security program and compliance with security policies. Entergy and the Registrant Subsidiaries’ risk management model addresses compliance with certain regulatory constructs, such as the NERC Reliability Standards, the NRC Code of Federal Regulations, the Payment Card Industry Data Security Standard, and the Health Insurance Portability and Accountability Act, among other regulations. Entergy and the Registrant Subsidiaries’ risk management model continuously evolves to improve and implement protections, controls, and monitoring to mitigate risks to their part of North America’s electric grid, to protect sensitive information, and to maintain secure business operations. Entergy and the Registrant Subsidiaries manage cybersecurity threats as an enterprise risk with close coordination and information sharing with its federal, state, and local partners. Entergy and the Registrant Subsidiaries also engage with local, state, and federal law enforcement agencies on initiatives to share threat information and participate in a wide range of industry collaborations and classified briefings on cybersecurity developments and evolving risks. Entergy and the Registrant Subsidiaries maintain access-management controls, including a layered multi-factor authentication process for network and system access, and a defense-in-depth security ecosystem that includes advanced threat detection from independent third parties and federal agencies, security logging and monitoring, and independent third-party penetration and vulnerability assessments. Relevant employees and contractors must complete cybersecurity trainings periodically to heighten security and threat awareness, promote best practices, and meet regulatory requirements. Additional multi-layered prevention and detection processes and technologies to mitigate and minimize the effects of cybersecurity risks include email security, continuous monitoring, vulnerability scanning, anti-virus and anti-malware software, backups and recovery strategy, network segregation, third-party security, and information protection. Entergy and the Registrant Subsidiaries have incorporated certain cyber-specific response protocols and procedures into their Entergy Incident Management System framework for responding to emergency incidents. This includes the Entergy Incident Response Team Plan, which outlines Entergy’s procedures, steps, and responsibilities for preparing for, detecting, containing, and recovering from an incident. The plan details the roles and responsibilities of Entergy’s officers who would be engaged in such a response to an emergency incident, including key questions to be addressed, critical decision points, and sources of key information to support decision-making. Senior management and the Emergency Incident Response Team periodically review and drill on the plan. As cybersecurity risks continue to evolve with multiple threat vectors, Entergy and the Registrant Subsidiaries maintain a comprehensive security strategy to keep current with the changing threats. To inform this effort, Entergy and the Registrant Subsidiaries utilize the National Institute of Standards and Technology Cybersecurity Framework, which consists of standards, guidelines, and best practices to manage cybersecurity risk across the enterprise. A risk-based approach is used to direct security initiatives to the most significant risks and provide the most value in terms of risk reduction and protection. Entergy and the Registrant Subsidiaries use a vendor risk management program to assess and monitor security risks that arise from certain third-party vendors. In addition, Entergy and the Registrant Subsidiaries utilize technology and threat-intelligence services to assess and continuously monitor the cybersecurity risk of key vendors, as identified through the vendor risk management program.

Cybersecurity Risk Materially Affected or Reasonably Likely to Materially Affect Registrant [Text Block]	While Entergy and the Registrant Subsidiaries have experienced cybersecurity incidents, except as otherwise summarized above or discussed elsewhere in this report, the risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected them including their business strategy, results of operations, or financial condition. See “ Item 1A. Risk Factors ” in Part I, Item 1A for a detailed description of the risks related to cybersecurity.
Cybersecurity Risk Board of Directors Oversight [Text Block]	The Board of Directors is responsible for oversight of the identification, management, and mitigation of enterprise-wide risk, including cybersecurity risk. The Audit Committee has the primary responsibility for overseeing risk management, including oversight of cybersecurity risk management practices and performance. The Audit Committee generally receives reports at each regular quarterly meeting provided by the CSO, the CISO, the CIO, and the General Auditor on the cybersecurity management program. The reports focus on the programs and protocols in place to mitigate cybersecurity risks, led by the CSO. Among other things, the reports may include: recent cyber risk and cybersecurity developments; industry engagement activities; legislative and regulatory developments; cyber-risk governance and oversight; selected cyber risk metrics and activities; cyber risk incident response plans and strategies; cybersecurity drills and exercises; assessments by third party experts and Internal Audit; and major projects and initiatives. While the Board of Directors and Audit Committee oversee cybersecurity risk management, Entergy’s management is responsible for managing cybersecurity risk. Entergy and the Registrant Subsidiaries’ security-risk-management system, as discussed above, is comprised of a three lines of defense model to enhance risk management efforts and define roles in the security program. The first line of defense, comprised of business units performing operational functions, including the CISO and CIO, is responsible for identification and management of security and reliability risks directly through design, implementation, and execution of control activities. The second line of defense, comprised of the CSO and Chief Security Office, performs and supports security and reliability risk management and governs and oversees the execution of security and reliability controls by the first line of defense. Ownership of specific security operations may migrate from a business unit in the first line of defense to the second line of defense, as determined to be appropriate by the Chief Security Office. The third line of defense, which includes Internal Audit, independent third parties, and certain regulatory constructs, such as the NERC Reliability Standards and the NRC Cyber Rule, provides assurance of selective actions taken by the first and second lines of defense to senior management and the Board of Directors. Entergy’s CSO is responsible for overseeing physical, cyber, and reliability risk, including governance, compliance, and threat intelligence. The CSO’s background includes serving as the Global Lead Business Information Security Officer for a multinational pharmaceutical and biotechnology company, Vice President of Cybersecurity Solutions for an international consulting firm, and an operations manager for a multinational technology company. The CSO is also a former intelligence officer in the U.S. Marine Corps, with experience in the Fleet Marine Force, Joint Staff J-2/Defense Intelligence Agency, and Headquarters Marine Corps Command, Control, Communications, and Computers (C4I). The CSO participated in numerous exercises and crisis operations during his time in the military. The CSO is a member of the Information Systems Audit and Control Association and a certified Information Privacy Manager from the International Association of Privacy Professionals. The CSO also completed the Harvard Kennedy School Executive Education Program in Cybersecurity and the FBI Domestic Security Executive Academy. Entergy’s CISO is responsible for enterprise strategic and operational cybersecurity, physical security systems, and regulatory compliance. The CISO oversees investments in tools, resources, and processes that allow for the continuous improvement and maturity of Entergy’s cybersecurity posture. The CISO has expertise spanning more than 25 years in the realm of information technology, information security, and cyber/physical security management. The CISO’s background includes serving as the Vice President and Chief Information Security Officer for an electric utility with responsibility for enterprise cybersecurity covering corporate, electric, nuclear, and gas operations. Additionally, the CISO served as the Chief Security Officer for the Electric Reliability Council of Texas with overall responsibility for its cybersecurity, physical security, and emergency management programs. Her previous experience includes multiple technical, managerial, and strategic roles within industries ranging from energy, telecommunication, software development, and cybersecurity consulting. The CISO is a Certified Information Systems Security Professional, Certified Information Security Manager, and Certified in Risk and Information Systems Control. Entergy’s CIO is responsible for ensuring that the organization’s information technology systems, infrastructure, and applications are designed, implemented, and maintained to provide secure and reliable performance in support of Entergy’s business objectives. The CIO establishes and enforces IT policies, procedures, and controls to mitigate information technology policies, procedures, and controls to mitigate information technology-related risks and provides guidance and support to the business units in the effective use of information technology resources and the management of information technology-related risks. By fulfilling these responsibilities across the three lines of defense model, the CIO plays a critical role in ensuring that Entergy’s information technology-related risks are effectively identified, managed, and mitigated, thereby supporting Entergy’s overall risk management and governance framework. The CIO’s background includes serving in senior leadership roles, including CIO for multiple global manufacturing companies, serving on the board of directors for a telecommunications company, and consulting leadership positions providing services for numerous large, global organizations. In the event of a suspected or actual cybersecurity incident, the Security Incident Response Team (SIRT), which includes the CISO, has primary responsibility for initial identification and evaluation of potential business impacts and escalation of the incident’s severity classification using pre-established criteria with a specified communication matrix and escalation thresholds. The Security Incident Commander, which role is served by rotating leaders in the CISO organization, provides tactical leadership and oversight management at the cross-functional level for the incident. The SIRT remains engaged throughout the incident response lifecycle, including detection and analysis, containment, eradication and recovery, and post-incident remediation, and coordinates with the impacted business functions, if warranted. Once a cyber incident is confirmed, the SIRT is responsible for maintaining situational awareness and continuous monitoring of the need for escalation or de-escalation of the incident’s severity classification. As certain escalation thresholds are exceeded, additional levels of management notification are required by the SIRT, including notification of and recurring communication with Entergy’s Incident Response Team, which includes the Chief Executive Officer, the Chief Operating Officer, the CSO, other executive management, and members of the affected business functions. Depending upon the facts, analysis, materiality, and anticipated or current impacts, the Chief Executive Officer and the General Counsel will determine the timing and cadence for communication of the cyber incident with the Board of Directors or Audit Committee.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2024
Use of Estimates, Policy [Policy Text Block]	Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used.
Revenues And Fuel Costs [Policy Text Block]	Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction.

The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements.
Outage Costs, Policy [Policy Text Block]	Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line.
Allowance for Funds Used During Construction, Policy [Policy Text Block]	Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets.
Income Tax, Policy [Policy Text Block]	Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment.
Public Utilities, Policy [Policy Text Block]	Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders.
Regulatory Income Taxes, Policy [Policy Text Block]	Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents.
Securitization Recovery Trust Accounts, Policy [Policy Text Block]	Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts.
Inventory, Policy	Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies.
Investment, Policy [Policy Text Block]	Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds.
Partnerships with disproportionate allocation of earnings and losses in relation to an investor's ownership interest [Policy Text Block]	Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets.
Assets Held-for-Sale, Policy	Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024.
Debt, Policy [Policy Text Block]	Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment.
Taxes Imposed On Revenue Producing Transactions, Policy [Policy Text Block]	Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these cases. Entergy is evaluating the effect the final rules will have on its disclosures and will continue to monitor developments related to the SEC’s stay of the rules and the litigation challenging such rules. In November 2024 the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” The ASU is intended to improve disclosures around income statement expenses by requiring disaggregated information within the footnotes to the financial statements about specific expense categories in commonly presented income statement expense captions. ASU 2024-03 is effective for Entergy for fiscal years beginning after December 15, 2026. Entergy does not expect ASU 2024-03 to materially affect its results of operations, financial positions, or cash flows.
Entergy Arkansas [Member]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used.
Revenues And Fuel Costs [Policy Text Block]	Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for the Registrant Subsidiaries by functional category, as of December 31, 2024 and 2023, is shown below: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Millions) Production Nuclear $1,887 $4,121 $— $— $— $2,016 Other 1,721 3,532 980 374 1,154 — Transmission 2,267 4,339 1,567 155 2,054 30 Distribution 3,615 4,973 2,418 761 2,554 — Other 606 1,175 385 384 318 44 Construction work in progress 320 762 487 20 1,513 85 Nuclear fuel 258 288 — — — 220 Property, plant, and equipment - net (a) $10,674 $19,190 $5,837 $1,694 $7,593 $2,395 (a) Includes $164 million of natural gas property, plant, and equipment and accumulated depreciation and $1 million of construction work in progress for Entergy Louisiana and $239 million of natural gas property, plant, and equipment and accumulated depreciation and $2 million of construction work in progress for Entergy New Orleans classified as held for sale in “Non-current assets held for sale” on their respective consolidated balance sheet as of December 31, 2024.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023.
Jointly Owned Generating Stations, Policy [Policy Text Block]	Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements.
Outage Costs, Policy [Policy Text Block]	Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line.
Allowance for Funds Used During Construction, Policy [Policy Text Block]	Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets.
Income Tax, Policy [Policy Text Block]	Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment.
Public Utilities, Policy [Policy Text Block]	Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders.
Regulatory Income Taxes, Policy [Policy Text Block]	Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents.
Securitization Recovery Trust Accounts, Policy [Policy Text Block]	Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts.
Inventory, Policy	Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies.
Investment, Policy [Policy Text Block]	Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds.
Partnerships with disproportionate allocation of earnings and losses in relation to an investor's ownership interest [Policy Text Block]	Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets.
Assets Held-for-Sale, Policy	Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024.
Debt, Policy [Policy Text Block]	Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment.
Taxes Imposed On Revenue Producing Transactions, Policy [Policy Text Block]	Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these cases. Entergy is evaluating the effect the final rules will have on its disclosures and will continue to monitor developments related to the SEC’s stay of the rules and the litigation challenging such rules. In November 2024 the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” The ASU is intended to improve disclosures around income statement expenses by requiring disaggregated information within the footnotes to the financial statements about specific expense categories in commonly presented income statement expense captions. ASU 2024-03 is effective for Entergy for fiscal years beginning after December 15, 2026. Entergy does not expect ASU 2024-03 to materially affect its results of operations, financial positions, or cash flows.

Use of Estimates, Policy [Policy Text Block]	Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used.
Revenues And Fuel Costs [Policy Text Block]	Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for the Registrant Subsidiaries by functional category, as of December 31, 2024 and 2023, is shown below: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Millions) Production Nuclear $1,887 $4,121 $— $— $— $2,016 Other 1,721 3,532 980 374 1,154 — Transmission 2,267 4,339 1,567 155 2,054 30 Distribution 3,615 4,973 2,418 761 2,554 — Other 606 1,175 385 384 318 44 Construction work in progress 320 762 487 20 1,513 85 Nuclear fuel 258 288 — — — 220 Property, plant, and equipment - net (a) $10,674 $19,190 $5,837 $1,694 $7,593 $2,395 (a) Includes $164 million of natural gas property, plant, and equipment and accumulated depreciation and $1 million of construction work in progress for Entergy Louisiana and $239 million of natural gas property, plant, and equipment and accumulated depreciation and $2 million of construction work in progress for Entergy New Orleans classified as held for sale in “Non-current assets held for sale” on their respective consolidated balance sheet as of December 31, 2024.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023.
Jointly Owned Generating Stations, Policy [Policy Text Block]	Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements.
Outage Costs, Policy [Policy Text Block]	Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line.
Allowance for Funds Used During Construction, Policy [Policy Text Block]	Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets.
Income Tax, Policy [Policy Text Block]	Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment.
Public Utilities, Policy [Policy Text Block]	Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders.
Regulatory Income Taxes, Policy [Policy Text Block]	Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents.
Securitization Recovery Trust Accounts, Policy [Policy Text Block]	Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts.
Inventory, Policy	Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies.
Investment, Policy [Policy Text Block]	Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets.
Assets Held-for-Sale, Policy	Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024.
Debt, Policy [Policy Text Block]	Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment.
Taxes Imposed On Revenue Producing Transactions, Policy [Policy Text Block]	Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these cases. Entergy is evaluating the effect the final rules will have on its disclosures and will continue to monitor developments related to the SEC’s stay of the rules and the litigation challenging such rules. In November 2024 the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” The ASU is intended to improve disclosures around income statement expenses by requiring disaggregated information within the footnotes to the financial statements about specific expense categories in commonly presented income statement expense captions. ASU 2024-03 is effective for Entergy for fiscal years beginning after December 15, 2026. Entergy does not expect ASU 2024-03 to materially affect its results of operations, financial positions, or cash flows.
Entergy Mississippi [Member]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used.
Revenues And Fuel Costs [Policy Text Block]	Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023.
Jointly Owned Generating Stations, Policy [Policy Text Block]	Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements.
Outage Costs, Policy [Policy Text Block]	Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line.
Allowance for Funds Used During Construction, Policy [Policy Text Block]	Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets.
Income Tax, Policy [Policy Text Block]	Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment.
Public Utilities, Policy [Policy Text Block]	Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders.
Regulatory Income Taxes, Policy [Policy Text Block]	Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents.
Securitization Recovery Trust Accounts, Policy [Policy Text Block]	Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts.
Inventory, Policy	Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies.
Investment, Policy [Policy Text Block]	Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds.
Partnerships with disproportionate allocation of earnings and losses in relation to an investor's ownership interest [Policy Text Block]	Partnerships with Disproportionate Allocation of Earnings and Losses in Relation to an Investor’s Ownership Interest Entergy Arkansas and Entergy Mississippi, as managing members, each control a tax equity partnership with a third party tax equity investor and consolidate the partnerships for financial reporting purposes. For each respective partnership, the limited liability company agreement with the tax equity investor stipulates a disproportionate allocation of tax attributes, earnings, and cash flows between the Registrant Subsidiary and the tax equity investor with the tax equity investor being allocated a significant portion of the tax attributes, earnings, and cash flows until it receives its target return, at which point the earnings and cash flows will primarily be allocated to the Registrant Subsidiary. Each Registrant Subsidiary has the option to purchase, at a future date specified in their respective partnership agreement, the tax equity investor’s interests at the then-current fair market value, plus an amount that results in the tax equity investor reaching its target return, if needed. Because of this disproportionate allocation, each Registrant Subsidiary accounts for its earnings in the partnership using the HLBV method of accounting. Under the HLBV method, the amounts of income and loss attributable to both the Registrant Subsidiary and the tax equity investor reflect changes in the amount each would hypothetically receive at the balance sheet date under the respective liquidation provisions of the limited liability company agreement, assuming the net assets of the partnership were liquidated at book value, after consideration of contributions and distributions, between the Registrant Subsidiary and the tax equity investor. Once the tax equity investor reaches its target return in the hypothetical liquidation, the remaining proceeds are primarily allocated to the Registrant Subsidiary. This allocation may result in fluctuations of income on a periodic basis that differ significantly from what would otherwise be recognized if the earnings were allocated under the relative ownership percentages between the Registrant Subsidiary and the tax equity investor. Entergy Arkansas and Entergy Mississippi have determined these differences are primarily due to timing, and both the APSC and the MPSC have approved that, for purposes of ratemaking, each Registrant Subsidiary reflect its interest in its respective partnership using its relative ownership percentage and disregard the effects of the HLBV method of accounting. Because of this, each Registrant Subsidiary has recorded a regulatory liability for the difference between the earnings allocated to it under the HLBV method of accounting and the earnings that would have been allocated to it under its respective ownership percentage in the partnership.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets.
Assets Held-for-Sale, Policy	Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024.
Debt, Policy [Policy Text Block]	Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment.
Taxes Imposed On Revenue Producing Transactions, Policy [Policy Text Block]	Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these cases. Entergy is evaluating the effect the final rules will have on its disclosures and will continue to monitor developments related to the SEC’s stay of the rules and the litigation challenging such rules. In November 2024 the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” The ASU is intended to improve disclosures around income statement expenses by requiring disaggregated information within the footnotes to the financial statements about specific expense categories in commonly presented income statement expense captions. ASU 2024-03 is effective for Entergy for fiscal years beginning after December 15, 2026. Entergy does not expect ASU 2024-03 to materially affect its results of operations, financial positions, or cash flows.
Entergy New Orleans [Member]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used.
Revenues And Fuel Costs [Policy Text Block]	Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for the Registrant Subsidiaries by functional category, as of December 31, 2024 and 2023, is shown below: 2024 Entergy Arkansas Entergy Louisiana Entergy Mississippi Entergy New Orleans Entergy Texas System Energy (In Millions) Production Nuclear $1,887 $4,121 $— $— $— $2,016 Other 1,721 3,532 980 374 1,154 — Transmission 2,267 4,339 1,567 155 2,054 30 Distribution 3,615 4,973 2,418 761 2,554 — Other 606 1,175 385 384 318 44 Construction work in progress 320 762 487 20 1,513 85 Nuclear fuel 258 288 — — — 220 Property, plant, and equipment - net (a) $10,674 $19,190 $5,837 $1,694 $7,593 $2,395 (a) Includes $164 million of natural gas property, plant, and equipment and accumulated depreciation and $1 million of construction work in progress for Entergy Louisiana and $239 million of natural gas property, plant, and equipment and accumulated depreciation and $2 million of construction work in progress for Entergy New Orleans classified as held for sale in “Non-current assets held for sale” on their respective consolidated balance sheet as of December 31, 2024.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023.
Jointly Owned Generating Stations, Policy [Policy Text Block]	Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements.
Outage Costs, Policy [Policy Text Block]	Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line.
Allowance for Funds Used During Construction, Policy [Policy Text Block]	Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets.
Income Tax, Policy [Policy Text Block]	Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment.
Public Utilities, Policy [Policy Text Block]	Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders.
Regulatory Income Taxes, Policy [Policy Text Block]	Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents.
Securitization Recovery Trust Accounts, Policy [Policy Text Block]	Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts.
Inventory, Policy	Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies.
Investment, Policy [Policy Text Block]	Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets.
Assets Held-for-Sale, Policy	Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024.
Debt, Policy [Policy Text Block]	Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment.
Taxes Imposed On Revenue Producing Transactions, Policy [Policy Text Block]	Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these cases. Entergy is evaluating the effect the final rules will have on its disclosures and will continue to monitor developments related to the SEC’s stay of the rules and the litigation challenging such rules. In November 2024 the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” The ASU is intended to improve disclosures around income statement expenses by requiring disaggregated information within the footnotes to the financial statements about specific expense categories in commonly presented income statement expense captions. ASU 2024-03 is effective for Entergy for fiscal years beginning after December 15, 2026. Entergy does not expect ASU 2024-03 to materially affect its results of operations, financial positions, or cash flows.

Use of Estimates, Policy [Policy Text Block]	Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used.
Revenues And Fuel Costs [Policy Text Block]	Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant. This results in Entergy and the Utility operating companies recording utility plant funded by customer advances at a net cost of zero, consistent with utility ratemaking treatment. As of December 31, 2024 and 2023, Entergy and the Utility operating companies have customer advances for construction as follows: 2024 2023 (In Millions) Entergy $635 $292 Entergy Arkansas $166 $96 Entergy Louisiana $292 $115 Entergy Mississippi $113 $33 Entergy New Orleans $1 $1 Entergy Texas $63 $47 Electric plant includes the portion of Grand Gulf that was sold and leased back in a prior period. For financial reporting purposes, this sale and leaseback arrangement is reported as a financing transaction. Net property, plant, and equipment (including property under lease and associated accumulated amortization) for Entergy by functional category, as of December 31, 2024 and 2023, is shown below: 2024 2023 (In Millions) Production Nuclear $8,024 $7,944 Other 7,809 7,045 Transmission 10,414 9,927 Distribution 14,321 12,927 Other 3,286 3,173 Construction work in progress 3,209 2,110 Nuclear fuel 766 708 Property, plant, and equipment - net (a) $47,829 $43,834 (a) Includes $403 million of natural gas property, plant, and equipment and accumulated depreciation and $3 million of construction work in progress classified as held for sale in “Non-current assets held for sale” on Entergy’s consolidated balance sheet as of December 31, 2024. See Note 14 to the financial statements for further discussion of the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses and the classification as held for sale. Depreciation rates on average depreciable property for Entergy approximated 2.9% in 2024, 2.9% in 2023, and 2.8% in 2022. Entergy amortizes nuclear fuel using a units-of-production method. Nuclear fuel amortization is included in fuel expense in the income statements. Non-utility property - at cost (less accumulated depreciation) for Entergy is reported net of accumulated depreciation of $231 million as of December 31, 2024 and $193 million as of December 31, 2023.

Non-utility property - at cost (less accumulated depreciation) for Entergy Mississippi is reported net of accumulated depreciation of $0.5 million as of December 31, 2024 and $0.5 million as of December 31, 2023.
Jointly Owned Generating Stations, Policy [Policy Text Block]	Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

(b) Ouachita Units 1 and 2 are owned 100% by Entergy Arkansas and Ouachita Unit 3 is owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the common facilities and not for the generating units. (c) Union Unit 1 is owned 100% by Entergy New Orleans, Union Unit 2 is owned 100% by Entergy Arkansas, Union Units 3 and 4 are owned 100% by Entergy Louisiana. The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements.
Outage Costs, Policy [Policy Text Block]	Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line.
Allowance for Funds Used During Construction, Policy [Policy Text Block]	Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets.
Income Tax, Policy [Policy Text Block]	Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment.
Public Utilities, Policy [Policy Text Block]	Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders.
Regulatory Income Taxes, Policy [Policy Text Block]	Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents.
Securitization Recovery Trust Accounts, Policy [Policy Text Block]	Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts.
Inventory, Policy	Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies.
Investment, Policy [Policy Text Block]	Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets.
Assets Held-for-Sale, Policy	Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024.
Debt, Policy [Policy Text Block]	Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment.
Taxes Imposed On Revenue Producing Transactions, Policy [Policy Text Block]	Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these cases. Entergy is evaluating the effect the final rules will have on its disclosures and will continue to monitor developments related to the SEC’s stay of the rules and the litigation challenging such rules. In November 2024 the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” The ASU is intended to improve disclosures around income statement expenses by requiring disaggregated information within the footnotes to the financial statements about specific expense categories in commonly presented income statement expense captions. ASU 2024-03 is effective for Entergy for fiscal years beginning after December 15, 2026. Entergy does not expect ASU 2024-03 to materially affect its results of operations, financial positions, or cash flows.

Use of Estimates, Policy [Policy Text Block]	Use of Estimates in the Preparation of Financial Statements In conformity with GAAP in the United States of America, the preparation of Entergy Corporation’s consolidated financial statements and the separate financial statements of the Registrant Subsidiaries requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities. Adjustments to the reported amounts of assets and liabilities may be necessary in the future to the extent that future estimates or actual results are different from the estimates used.
Revenues And Fuel Costs [Policy Text Block]	Revenues and Fuel Costs See Note 19 to the financial statements for a discussion of Entergy’s and the Registrant Subsidiaries’ revenues and fuel costs.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment is stated at original cost less regulatory disallowances and impairments. Depreciation is computed on the straight-line basis at rates based on the applicable estimated service lives of the various classes of property. For the Registrant Subsidiaries, the original cost of plant retired or removed, less salvage, is charged to accumulated depreciation. Normal maintenance, repairs, and minor replacement costs are charged to operating expenses. Certain combined-cycle gas turbine generating units are maintained under long-term service agreements with third-party service providers. The costs under these agreements are split between operating expenses and capital additions based upon the nature of the work performed. Substantially all of the Registrant Subsidiaries’ plant is subject to mortgage liens. Customers may be required to make advance payments for construction of new utility plants to reimburse the Utility operating companies for costs that are not expected to be recovered through existing retail rates. Under the regulatory framework, these payments are required to ensure the cost to serve a particular customer does not increase the utility rates charged to other utility customers. These advance payments do not reduce the retail rate charged to the customer making the payment and do not create any additional obligation for the respective Utility operating company to provide electrical service beyond the general obligation to serve all customers in its service area. Because the cost is fully reimbursed by the customer through the advance payment, the Utility operating company does not earn a return or recover through retail rates the cost of utility plants reimbursed by these payments. These advance payments are initially recorded as a non-current liability, which is then reduced by the costs incurred to construct the associated utility plant.

Jointly Owned Generating Stations, Policy [Policy Text Block]	Jointly-Owned Generating Stations Certain Entergy subsidiaries jointly own electric generating facilities with affiliates or third parties. All parties are required to provide their own financing. The investments, fuel expenses, and other operation and maintenance expenses associated with these generating stations are recorded by the Entergy subsidiaries to the extent of their respective undivided ownership interests. As of December 31, 2024, the subsidiaries’ investment and accumulated depreciation in each of these generating stations were as follows: Generating Stations Fuel Type Total Megawatt Capability (a) Ownership Investment Accumulated Depreciation (In Millions) Utility: Entergy Arkansas - Independence Unit 1 Coal 820 31.50 % $152 $109 Independence Common Facilities Coal 15.75 % $42 $32 White Bluff Units 1 and 2 Coal 1,244 57.00 % $622 $412 Ouachita (b) Common Facilities Gas 66.67 % $174 $160 Union (c) Common Facilities Gas 25.00 % $29 $13 Entergy Louisiana - Roy S.

The investment and accumulated depreciation numbers above are only for the specified common facilities and not for the generating units. (d) Includes a leasehold interest held by System Energy. System Energy’s Grand Gulf lease obligations are discussed in Note 5 to the financial statements.
Outage Costs, Policy [Policy Text Block]	Nuclear Refueling Outage Costs Nuclear refueling outage costs are deferred during the outage and amortized over the estimated period to the next outage because these refueling outage expenses are incurred to prepare the units to operate for the next operating cycle without having to be taken off line.
Allowance for Funds Used During Construction, Policy [Policy Text Block]	Allowance for Funds Used During Construction (AFUDC) AFUDC represents the approximate net composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction by the Registrant Subsidiaries. AFUDC increases both the plant balance and earnings and is realized in cash through depreciation provisions included in the rates charged to customers. Certain large industrial customers make advance payments to provide Entergy and the Utility operating companies the return on their investment in utility plant that they would otherwise have received by the recognition of AFUDC. When such advances are made, AFUDC is not added to the associated utility plant, which results in a lower amount of utility plant recovered through utility rates. These advance payments are initially recorded as a current liability and then amortized to income over the construction period of the related plant. As of December 31, 2024, Entergy and Entergy Louisiana have $152 million in such advances from customers recorded as current liabilities on their respective consolidated balance sheets.
Income Tax, Policy [Policy Text Block]	Income Taxes Entergy Corporation and the majority of its subsidiaries file a United States consolidated federal income tax return. Each tax-paying entity records income taxes as if it were a separate taxpayer and consolidating adjustments are allocated to the tax filing entities in accordance with Entergy’s intercompany income tax allocation agreements. Deferred income taxes are recorded for temporary differences between the book and tax basis of assets and liabilities, and for certain losses and credits available for carryforward. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates in the period in which the tax or rate was enacted. See the “ Other Tax Matters - Tax Cuts and Jobs Act ” section in Note 3 to the financial statements for discussion of the effects of the enactment of the Tax Cuts and Jobs Act in December 2017. The benefits of investment tax credits are deferred and amortized over the average useful life of the related property, as a reduction of income tax expense, for such credits associated with rate-regulated operations in accordance with ratemaking treatment.
Public Utilities, Policy [Policy Text Block]	Accounting for the Effects of Regulation Entergy’s Utility operating companies and System Energy are rate-regulated entities that are required to reflect the effects of rate regulation in their financial statements, including the recording of regulatory assets and liabilities, as the Utility operating companies and System Energy have rates that meet the following three criteria: (1) are approved by a third-party regulator; (2) are designed to recover the entities’ cost of providing the regulated services or products; and (3) can reasonably be assumed will be charged to and collected from customers. These criteria may also be applied to separable portions of a utility’s business, such as the generation or transmission functions, or to specific classes of customers. Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be credited to customers through future regulated rates or (2) billings in advance of expenditures for approved regulatory programs. To the extent that all or portions of the Utility operating companies or System Energy’s operations cease to be subject to rate regulation, or future recovery or settlement is no longer probable as a result of changes in regulation or other reasons, the related regulatory assets and liabilities are eliminated from the balance sheet and the impact is recognized on the income statement. In addition, regulatory accounting requires recognition of an impairment loss if it becomes probable that part of the cost of a recently completed plant asset will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made. Entergy Louisiana does not apply regulatory accounting standards to the Louisiana retail deregulated portion of River Bend or to the 30% interest in River Bend formerly owned by Cajun unless specific cost recovery is provided for in tariff rates. The Louisiana retail deregulated portion of River Bend is operated under a deregulated asset plan representing a portion (approximately 15%) of River Bend plant costs, generation, revenues, and expenses established under a 1992 LPSC order. The plan allows Entergy Louisiana to sell the electricity from the deregulated assets to Louisiana retail customers at 4.6 cents per kWh or off-system at higher prices, with certain provisions for sharing incremental revenue above 4.6 cents per kWh between customers and shareholders.
Regulatory Income Taxes, Policy [Policy Text Block]	Regulatory Asset or Liability for Income Taxes Accounting standards for income taxes provide that a regulatory asset or liability be recorded if it is probable that the currently determinable future increase or decrease in regulatory income tax expense will be recovered from or credited to customers through future rates. There are two main sources of Entergy’s regulatory asset or liability for income taxes. There is a regulatory asset related to the ratemaking treatment of the tax effects of book depreciation for the equity component of AFUDC that has been capitalized to property, plant, and equipment but for which there is no corresponding tax basis. Equity-AFUDC is a component of property, plant, and equipment that is included in rate base when the plant is placed in service. There is a regulatory liability related to the adjustment of Entergy’s net deferred income taxes that was required by the enactment in December 2017 of a change in the federal corporate income tax rate, which is discussed in Note 2 and 3 to the financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Entergy considers all unrestricted highly liquid debt instruments with an original maturity of three months or less at date of purchase to be cash equivalents.
Securitization Recovery Trust Accounts, Policy [Policy Text Block]	Securitization Recovery Trust Accounts The funds that Entergy New Orleans and Entergy Texas hold in their securitization recovery trust accounts are not classified as cash and cash equivalents or restricted cash and cash equivalents because of their nature, uses, and restrictions. These funds are classified as part of other current assets and other investments, depending on the timeframe within which the Registrant Subsidiary expects to use the funds.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects Entergy’s best estimate of expected losses on its accounts receivable balances. The allowance is calculated as the historical rate of customer write-offs multiplied by the current accounts receivable balance, taking into account the length of time the receivable balances have been outstanding. Although the rate of customer write-offs has historically experienced minimal variation, management monitors the current condition of individual customer accounts to manage collections and ensure bad debt expense is recorded in a timely manner. The Utility operating companies’ customer accounts receivable are written off consistent with approved regulatory requirements. See Note 19 to the financial statements for further details on the allowance for doubtful accounts.
Inventory, Policy	Materials and Supplies Materials and supplies consist of tangible goods, equipment, and other materials that Entergy holds for use or consumption in the normal course of business, whether for capital projects or operation and maintenance activities, or that are required to be kept for regulatory reasons or service reliability. Materials and supplies are valued at a weighted average unit cost when expensed or capitalized, as appropriate, when used or installed. Materials and supplies are valued at the lower of weighted average cost or net realizable value, net of provisions for excess and obsolete materials and supplies.
Investment, Policy [Policy Text Block]	Investments Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets. For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Decommissioning trust funds for the nuclear plants previously owned by Entergy’s non-utility operations, all of which have been sold as of June 2022, did not meet the criteria for regulatory accounting treatment. Accordingly, unrealized gains/(losses) recorded on the equity securities in the trust funds for these plants were recognized in earnings with no offsetting regulatory liability/asset amount. Unrealized gains/(losses) recorded on the available-for-sale debt securities in the trust funds were recognized in the accumulated other comprehensive income component of shareholders’ equity. Entergy’s trusts are managed by third parties who operate in accordance with agreements that define investment guidelines and place restrictions on the purchases and sales of investments. See Note 16 to the financial statements for details on the decommissioning trust funds.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Commodity Derivatives The accounting standards for derivative instruments and hedging activities require that all derivatives be recognized at fair value on the balance sheet, either as assets or liabilities, unless they meet various exceptions including the normal purchase/normal sale criteria. The changes in the fair value of recognized derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Due to regulatory treatment, an offsetting regulatory asset or liability is recorded for changes in fair value of recognized derivatives for the Registrant Subsidiaries. Contracts for commodities that will be physically delivered in quantities expected to be used or sold in the ordinary course of business, including certain purchases and sales of power and fuel, meet the normal purchase, normal sales criteria and are not recognized on the balance sheet. Revenues and expenses from these contracts are reported on a gross basis in the appropriate revenue and expense categories as the commodities are received or delivered. Entergy has determined that contracts to purchase uranium do not meet the definition of a derivative under the accounting standards for derivative instruments because they do not provide for net settlement and the uranium markets are not sufficiently liquid to conclude that forward contracts are readily convertible to cash. If the uranium markets do become sufficiently liquid in the future and Entergy begins to account for uranium purchase contracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Entergy’s other derivative instruments. See Note 15 to the financial statements for further details on Entergy’s derivative instruments and hedging activities.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Values The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling. Considerable judgment is required in developing the estimates of fair value. Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange. Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments. See Note 15 to the financial statements for further discussion of fair value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Entergy periodically reviews long-lived assets whenever events or changes in circumstances indicate that recoverability of these assets is uncertain. Generally, the determination of recoverability is based on the undiscounted net cash flows expected to result from such operations and assets. Projected net cash flows depend on the expected operating life of the assets, the future operating costs associated with the assets, the efficiency and availability of the assets and generating units, and the future market and price for energy and capacity over the remaining life of the assets.
Assets Held-for-Sale, Policy	Assets Held for Sale A long-lived asset or component of an entity meets the criteria to be classified as held for sale, generally, when management with requisite approvals commits to a plan to sell and it is probable that the sale will be completed within one year. When held for sale criteria is met, the assets and liabilities of the disposal group are separately presented as assets and liabilities held for sale on the balance sheet. Any long-lived assets of the disposal group are measured at the lower of their carrying value or their estimated fair value less costs to sell. If the disposal group meets the definition of a business, then a portion of any goodwill with that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As described in Note 14 to the financial statements, the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses met the criteria to be to classified as held for sale as of December 31, 2024.
Debt, Policy [Policy Text Block]	Reacquired Debt The premiums and costs associated with reacquired debt of Entergy’s Utility operating companies and System Energy (except that portion allocable to the deregulated operations of Entergy Louisiana) are included in regulatory assets and are being amortized over the life of the related new issuances, or over the life of the original debt issuance if the debt is not refinanced, in accordance with ratemaking treatment.
Taxes Imposed On Revenue Producing Transactions, Policy [Policy Text Block]	Taxes Imposed on Revenue-Producing Transactions Governmental authorities assess taxes that are both imposed on and concurrent with a specific revenue-producing transaction between a seller and a customer, including, but not limited to, sales, use, value added, and some excise taxes. Entergy presents these taxes on a net basis, excluding them from revenues, unless required to report them differently by a regulatory authority.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements The accounting standard-setting process is ongoing, and the FASB is currently working on several projects that have not yet resulted in final pronouncements. Final pronouncements that result from these projects could have a material effect on Entergy’s future results of operations, financial positions, or cash flows. In December 2023 the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU require enhanced income tax disclosures, primarily related to consistent categorization and disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also removes certain disclosures that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for Entergy for fiscal years beginning after December 15, 2024. Entergy does not expect ASU 2023-09 to materially affect its results of operations, financial positions, or cash flows. In March 2024 the SEC issued final rules that require registrants to provide certain climate-related disclosures in annual reports and registration statements in order to enhance and standardize climate-related disclosures for investors. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant’s board of directors’ oversight of climate-related risks and management’s role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant’s business, results of operations, or financial condition. In addition, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions on a phased-in basis by certain larger registrants when those emissions are material; the filing of an attestation report covering the required disclosure of such registrant’s Scope 1 and/or Scope 2 emissions, also on a phased-in basis; and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules provide that the phase-in compliance period is effective for Entergy beginning with its annual report for the fiscal year ending December 31, 2025. In April 2024 the SEC stayed the final rules, pending judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. In February 2025 the Acting SEC Chairman directed the SEC staff to request that the court not schedule the case for argument to provide time for the SEC to deliberate and determine the appropriate next steps in these cases. Entergy is evaluating the effect the final rules will have on its disclosures and will continue to monitor developments related to the SEC’s stay of the rules and the litigation challenging such rules. In November 2024 the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” The ASU is intended to improve disclosures around income statement expenses by requiring disaggregated information within the footnotes to the financial statements about specific expense categories in commonly presented income statement expense captions. ASU 2024-03 is effective for Entergy for fiscal years beginning after December 15, 2026. Entergy does not expect ASU 2024-03 to materially affect its results of operations, financial positions, or cash flows.

(b) Common stocks, preferred stocks, and certain fixed income debt securities (government) are stated at fair value determined by quoted market prices. (c) The common collective trusts hold investments in accordance with stated objectives. The investment strategy of the trusts is to capture the growth potential of equity markets by replicating the performance of a specified index. The issuer of these funds allows daily trading at the net asset value and trades settle at a later date, with no other trading restrictions. Net asset value per share of common collective trusts estimate fair value. Common collective trusts are not publicly quoted and are valued by the fund administrators using net asset value as a practical expedient. Accordingly, these funds are not assigned a level in the fair value table, but are included in the total. (d) Registered investment companies are money market mutual funds with a stable net asset value of one dollar per share. Registered investment companies may hold investments in domestic and international bond markets or domestic equities valued at the daily closing price as reported by the fund. These funds are required to publish their daily net asset value and to transact at that price. The money market mutual funds held by the trusts are deemed to be actively traded. Certain registered investment companies are recorded at contract value, which approximates fair value. (e) Certain of these registered investment companies are not publicly quoted and are valued by the fund administrators using net asset value as a practical expedient. The issuer of these funds allows daily trading at the net asset value and trades settle at a later date, with no other trading restrictions. Accordingly, these funds are not assigned a level in the fair value table, but are included in the total. (f) The other remaining assets are U.S. municipal and foreign government bonds stated at fair value as determined by broker quotes. (g) The unallocated insurance contract investments are recorded at contract value, which approximates fair value. The contract value represents contributions made under the contract, plus interest, less funds used to pay benefits and contract expenses, and less distributions to the master trust.
