Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 — Summary of Significant Accounting Policies Discontinued Operations In March 2023, Cleco Holdings’ management, with the support of its Board of Managers, committed to a plan of action for the disposition of the Cleco Cajun Sale Group. As a result, Cleco Holdings’ management determined that the criteria under GAAP for the Cleco Cajun Sale Group to be classified as held for sale were met, and the sale represents a strategic shift that will have a major effect on Cleco’s future operations and financial results. Therefore, the results of operations and financial position of the Cleco Cajun Sale Group have been presented as discontinued operations since March 31, 2023. On June 1, 2024, the Cleco Cajun Divestiture closed. For more information, see Note 3 — “Discontinued Operations.” Principles of Consolidation The accompanying condensed consolidated financial statements of Cleco include the accounts of Cleco Holdings and its majority-owned subsidiaries after elimination of intercompany accounts and transactions. Basis of Presentation The condensed consolidated financial statements of Cleco and Cleco Power have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. The year-end condensed consolidated balance sheet data was derived from audited financial statements and adjusted for discontinued operations. Because the interim condensed consolidated financial statements and the accompanying notes do not include all of the information and notes required by GAAP for annual financial statements, the condensed consolidated financial statements and other information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes in the Registrants’ Combined Annual Report on Form 10-K for the fiscal year ended December 31, 2023. These condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments that are necessary for a fair statement of the financial position and results of operations of Cleco and Cleco Power. Amounts reported in Cleco’s and Cleco Power’s interim financial statements are not necessarily indicative of amounts expected for the annual periods due to the effects of seasonal temperature variations on energy consumption, regulatory rulings, the timing of maintenance on electric generating units, changes in mark-to-market valuations, changing commodity prices, discrete income tax items, and other factors. In preparing financial statements that conform to GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. For information on recent authoritative guidance and its effect on financial results, see Note 2 — “Recent Authoritative Guidance.” For information on discontinued operations, see Note 3 — “Discontinued Operations.” Various agreements to which Cleco is subject contain covenants that restrict its use of cash. As certain provisions under these agreements are met, cash is transferred out of related escrow accounts and becomes available for its intended purposes and/or general corporate purposes. Cleco’s and Cleco Power’s restricted cash and cash equivalents consisted of the following: Cleco (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Current Cleco Securitization I’s operating expenses and storm recovery bond issuance costs and debt service $ 7,537 $ 15,818 Total current 7,537 15,818 Non-current Diversified Lands’ mitigation escrow 24 24 Cleco Power’s future storm restoration costs 118,110 113,549 Total non-current 118,134 113,573 Total restricted cash and cash equivalents $ 125,671 $ 129,391 Cleco Power (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Current Cleco Securitization I’s operating expenses and storm recovery bond issuance costs and debt service $ 7,537 $ 15,818 Total current 7,537 15,818 Non-current Future storm restoration costs 118,110 113,549 Total non-current 118,110 113,549 Total restricted cash and cash equivalents $ 125,647 $ 129,367 Reserves for Credit Losses Customer accounts receivable are recorded at the invoiced amount and do not bear interest. Customer accounts receivable are generally considered past due 20 days after the billing date. Cleco recognizes write-offs within the allowance for credit losses once all recovery methods have been exhausted. It is the policy of management to review accounts receivable and unbilled revenue monthly using a reserve matrix based on historical bad debt write-offs, as well as current and forecasted economic conditions, to establish a credit loss estimate. Management’s historical credit loss analysis included periods of economic recessions, natural disasters, and temporary changes to collection policies. Due to the critical necessity of electricity, these past events have not significantly impacted Cleco’s credit loss rates. Cleco’s credit losses at September 30, 2024, were within range of its historical credit loss analysis.

Recent Authoritative Guidance	Sep. 30, 2024
Accounting Changes and Error Corrections [Abstract]
Recent Authoritative Guidance	Note 2 — Recent Authoritative Guidance In March 2023, FASB issued guidance that applies to leases between entities under common control. The guidance provides a practical expedient for determining whether an arrangement between entities under common control is a lease as well as the classification of the lease. In addition, the leasehold improvements amortization period is to be determined by the useful life to the common group rather than the term of the lease. The new guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Cleco has arrangements between entities under common control. The implementation of this guidance did not have a material impact on the results of operations, financial condition, or cash flows of the Registrants. In November 2023, FASB issued guidance to improve reportable segment disclosure requirements. The guidance enhances interim disclosure requirements, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss, provides new segment disclosure requirements for entities with a single reportable segment, and contains other disclosure requirements. Disclosure requirements include disclosing significant segment expenses by reportable segment if they are regularly provided to the chief operating decision maker and included in each reported measure of segment profit or loss. Disclosures are required on both an annual and an interim basis. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Management does not expect this guidance to have a significant impact on the results of operations, financial condition, or cash flows of the Registrants.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Note 3 — Discontinued Operations In March 2023, Cleco Holdings’ management, with the support of its Board of Managers, committed to a plan of action for the disposition of the Cleco Cajun Sale Group. As a result, Cleco Holdings’ management determined that the criteria under GAAP for the Cleco Cajun Sale Group to be classified as held for sale were met, and the sale represents a strategic shift that will have a major effect on Cleco’s future operations and financial results. Therefore, the results of operations and financial position of the Cleco Cajun Sale Group have been presented as discontinued operations since March 31, 2023. Certain expenses incurred by the Cleco Cajun Sale Group as a result of common services provided by Support Group are reflected in Cleco’s results of continuing operations due to the expected ongoing nature of those expenses. In addition, revenue recognized by Cleco Power from transmission services provided to the Cleco Cajun Sale Group is no longer eliminated upon consolidation of Cleco’s financial statements and is reflected in Cleco’s results of continuing operations due to the ongoing nature of these services. On June 1, 2024, the Cleco Cajun Sellers completed the sale of the Cleco Cajun Sale Group. Upon closing, the Cleco Cajun Sellers received $474.5 million, net of adjustments as set forth in the Cleco Cajun Divestiture Purchase and Sale Agreement and adjustments based on net working capital. Also, in conjunction with the closing of the Cleco Cajun Divestiture, the Cleco Cajun Sellers paid $10.8 million to professional service firms that were engaged to facilitate the transaction. Cleco expects to receive an additional $113.0 million 24 months after closing, which is not contingent upon the post-divestiture performance of the divested business. This receivable is discounted to its net present value and recorded in Receivable - Cleco Cajun Divestiture on Cleco’s Condensed Consolidated Balance Sheet. In connection with the sale, Cleco entered into an other services agreement and a transition services agreement to provide certain services to the Cleco Cajun Purchasers for up to twelve months. In February 2019 in connection with the approval of the Cleco Cajun Acquisition, Cleco made commitments to the LPSC that included the repayment of $400.0 million of Cleco Holdings’ debt by December 31, 2024. On April 26, 2024, the remaining $66.7 million of that debt was paid and this LPSC commitment was satisfied. Interest expense on that debt is included in discontinued operations. Cleco determined that the estimated fair value less the estimated cost to sell the Cleco Cajun Sale Group was less than the carrying value of the Cleco Cajun Sale Group. As a result, the Cleco Cajun Sale Group had an impairment of $173.0 million at December 31, 2023. During the three months ended March 31, 2024, an additional impairment charge of $17.0 million was recorded. On June 1, 2024, the Cleco Cajun Divestiture closed, and an incremental $27.1 million loss on the sale of the Cleco Cajun Sale Group was recorded. This resulted in a cumulative loss related to the Cleco Cajun Divestiture of $217.1 million. The incremental loss on the sale of the Cleco Cajun Sale Group recognized during the three months ended June 30, 2024, was the difference between the fair value of the proceeds received and the derecognized net assets of the Cleco Cajun Sale Group on the closing date. During the three months ended September 30, 2024, the working capital adjustments related to the Cleco Cajun Divestiture were finalized and resulted in a $0.4 million decrease to the loss on the Cleco Cajun Divestiture that was previously recorded. The following table presents the amounts that have been reclassified from continuing operations and included in discontinued operations within Cleco’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2024, and 2023: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2024 2023 2024 2023 Operating revenue, net Electric operations $ — $ 153,025 $ 207,555 $ 385,249 Other operations — 34,231 50,992 95,413 Operating revenue, net — 187,256 258,547 480,662 Operating expenses Fuel used for electric generation 5 41,339 21,061 70,053 Purchased power 52 67,297 93,087 175,884 Other operations and maintenance 33 28,611 37,623 75,926 Depreciation and amortization 65 433 4,336 15,448 Total operating expenses 155 137,680 156,107 337,311 Operating (loss) income (155) 49,576 102,440 143,351 Other (expense) income, net — (7) 239 125 Interest, net 643 (1,835) 1,225 (5,545) Gain (loss) - Cleco Cajun Divestiture (1) 360 (38,000) (43,715) (154,000) Income (loss) from discontinued operations before income taxes 848 9,734 60,189 (16,069) Federal and state income tax expense (benefit) 106 152,463 14,774 (6,362) Income (loss) from discontinued operations, net of income taxes $ 742 $ (142,729) $ 45,415 $ (9,707) (1) This represents the loss on the classification as held for sale until the closing of the Cleco Cajun Divestiture.

Regulatory Assets and Liabilities	Sep. 30, 2024
Regulated Operations [Abstract]
Regulatory Assets and Liabilities	Note 5 — Regulatory Assets and Liabilities Cleco Power recognizes an asset for certain costs capitalized or deferred for recovery from customers and recognizes a liability for amounts expected to be returned to customers or collected for future expected costs. Cleco Power records these assets and liabilities based on regulatory approval and management’s ongoing assessment that it is probable these items will be recovered or refunded through the ratemaking process. Under the current regulatory environment, Cleco Power believes these regulatory assets will be fully recoverable. If in the future, as a result of regulatory changes or competition, Cleco Power’s ability to recover these regulatory assets would no longer be probable, then to the extent that such regulatory assets were determined not to be recoverable, Cleco Power would be required to write-down such assets. In addition, potential deregulation of the industry, or possible future changes in the method of rate regulation of Cleco Power, could require discontinuance of the application of the authoritative guidance on regulated operations. The following table summarizes Cleco Power’s regulatory assets and liabilities: Cleco Power REMAINING RECOVERY PERIOD (YRS.)

(9) Beginning July 1, 2024, the lost revenues and incremental costs associated with the COVID-19 executive order are being amortized over three years as approved by the LPSC in May 2024. The following table summarizes Cleco’s net regulatory assets and liabilities: Cleco (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Total Cleco Power regulatory assets, net $ 470,591 $ 454,213 2016 Merger adjustments (1) Fair value of long-term debt 91,794 97,345 Postretirement costs 7,958 9,448 Financing costs 6,302 6,560 Debt issuance costs 4,004 4,254 Total Cleco regulatory assets, net $ 580,649 $ 571,820 (1) Cleco regulatory assets include acquisition accounting adjustments as a result of the 2016 Merger. Deferred Lignite and Mine Closure Costs and Dolet Hills Power Station Closure Costs In 2020, Cleco Power and SWEPCO made a joint filing with the LPSC seeking authorization to close the Oxbow mine and to include and defer certain accelerated mine closing costs in fuel and related ratemaking treatment. In 2021, the LPSC approved the establishment of a regulatory asset for certain lignite costs that would otherwise be billed through Cleco Power’s FAC and any reasonable incremental third-party professional costs related to the closure of the mine. In 2020, Cleco Power revised depreciation rates for the Dolet Hills Power Station to utilize the December 31, 2021, expected end-of-life and early retirement of the Dolet Hills Power Station and defer depreciation expense to a regulatory asset for the amount in excess of the previously approved depreciation rates by the LPSC. The Dolet Hills Power Station was retired on December 31, 2021. In 2022, Cleco Power filed an application with the LPSC requesting approval of the regulatory treatment and recovery of stranded and decommissioning costs associated with the retirement of the Dolet Hills Power Station over 20 years as well as recovery of deferred fuel and mine-related costs. On April 19, 2024, the LPSC approved an uncontested settlement that contains a provision for a $40.0 million reduction in the regulatory asset associated with the Dolet Hills Power Station. This amount was recorded as a reduction to the associated regulatory asset on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets and an increase to Depreciation and amortization on Cleco’s and Cleco Power’s Statements of Income. At June 30, 2024, $12.3 million of the ARO regulatory asset, which is related to the Dolet Hills Power Station, was reclassified to the Dolet Hills Power Station Closure Costs regulatory asset. This amount was included in the related securitization application filed with the LPSC on May 17, 2024. Management anticipates the securitization of these costs to close by the end of March 2025, and as a result, reclassified these costs as current Regulatory assets on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. For more information about the settlement, see Note 14 — “ Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees — Litigation — LPSC Audits and Reviews — Dolet Hills Prudency Review.” Solar Development Costs In July 2022, Cleco Power entered into a long-term agreement to purchase, among other things, the output, capacity, and current and future environmental resource credits of a 240-MW solar electric generation facility to be constructed in DeSoto Parish, Louisiana and owned by a third party. On September 17, 2024, the LPSC approved the agreement and authorized Cleco Power to establish a regulatory asset for the stipulated settlement of development costs incurred through December 31, 2023, associated with the long-term agreement. As approved by the LPSC, Cleco Power will begin amortizing these costs over 25 years once it begins purchasing power from the third party, which is expected by January 2027. Residential Revenue Decoupling Under the terms of Cleco Power’s new FRP, effective July 1, 2024, Cleco Power implemented a residential revenue decoupling mechanism through its infrastructure and incremental cost recovery rider that provides a charge or credit to its residential customers for any under or over collection of residential base revenue as a result of changes in usage driven by weather or other measures. The under or over collection of residential base revenue is assessed on Cleco Power’s rate year and an associated credit or charge for decoupling, not to exceed $3.0 million, will be adjusted for the infrastructure and incremental cost recovery rider filings for July 2025 and 2026, respectively. Storm Reserves Cleco Power has a storm reserve to fund future storm restoration costs. Accumulated storm restoration costs that are probable of recovery from retail customers are netted against the storm reserve. At December 31, 2023, Cleco Power had a storm reserve balance of $111.5 million, net of $2.5 million of accumulated restoration costs. During 2024, Cleco Power’s service territory was impacted by multiple severe weather events resulting in significant storm restoration costs. At September 30, 2024, Cleco Power had a storm reserve balance of $81.2 million, net of $37.3 million of accumulated storm restoration costs. For more information on the storm restoration costs associated with severe weather events that impacted Cleco Power’s service territory, see Note 18 — “Storm Restoration.”

Fair Value Disclosures [Abstract]
Fair Value Accounting Instruments	Note 6 — Fair Value Accounting Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Cleco utilizes a three-tier fair value hierarchy that prioritizes inputs that may be used to measure fair value. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. All assets and liabilities are required to be classified in their entirety based on the lowest level of input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and its placement within the fair value hierarchy. Significant increases or decreases in any of those inputs in isolation could result in a significantly different fair value measurement. Cleco classifies fair value balances based on the fair value hierarchy defined as follows: • Level 1 — observable inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that Cleco can observe as of the measurement date. • Level 2 — observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities in active markets, quoted market prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — unobservable inputs for assets or liabilities whose fair value is estimated based on internally or third-party developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost-benefit constraints. When available, Cleco uses observable market prices to measure fair value. Credit risk of Cleco and its counterparties is incorporated in the valuation of assets and liabilities through the use of credit reserves. Cleco applies the provisions of the fair value measurement standard to its non-recurring, non-financial measurements including business combinations as well as impairment related to goodwill and other long-lived assets. Fair Value Measurements on a Recurring Basis The amounts reflected in Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets at September 30, 2024, and December 31, 2023, for cash equivalents, restricted cash equivalents, accounts receivable, other accounts receivable, short-term debt, and accounts payable approximate fair value because of their short-term nature. The following tables disclose the fair value of financial assets and liabilities measured on a recurring basis on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. These amounts are presented on a gross basis.

During the nine months ended September 30, 2024, and the year ended December 31, 2023, Cleco did not experience any transfers into or out of Level 3 of the fair value hierarchy. Short-term Investments At September 30, 2024, and December 31, 2023, Cleco and Cleco Power had short-term investments in money market funds and treasury bills that have a maturity of three months or less when purchased. The following tables present the short-term investments as recorded on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets at September 30, 2024, and December 31, 2023: Cleco (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Cash and cash equivalents $ 239,557 $ 113,207 Current restricted cash and cash equivalents $ 7,537 $ 15,818 Non-current restricted cash and cash equivalents $ 118,134 $ 113,571 Cleco Power (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Cash and cash equivalents $ 40,557 $ 40,240 Current restricted cash and cash equivalents $ 7,537 $ 15,818 Non-current restricted cash and cash equivalents $ 118,110 $ 113,548 FTRs FTRs are financial instruments used to provide a financial hedge to manage the risk of transmission congestion charges between MISO nodes in MISO’s Day-Ahead Energy Market. Cleco is awarded and/or purchases FTRs in auctions facilitated by MISO. FTRs are derivatives not designated as hedging instruments for accounting purposes. FTRs are valued using MISO’s monthly auction prices as a price index reference (Level 3). Unrealized gains or losses are deferred as a component of Accumulated deferred fuel on the balance sheet in accordance with regulatory policy, and at settlement, realized gains or losses are included in Cleco Power’s FAC and reflected on customers’ bills as a component of the fuel charge. The following table summarizes the changes in the net fair value of FTR assets and liabilities classified as Level 3 in the fair value hierarchy for Cleco and Cleco Power: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2024 2023 2024 2023 Balances, beginning of period $ 3,548 $ 6,459 $ 2,306 $ 2,276 Unrealized (losses) gains * (156) 114 (108) (186) Purchases (7) 12 4,242 8,035 Settlements (1,001) (2,442) (4,056) (5,982) Balances, end of period $ 2,384 $ 4,143 $ 2,384 $ 4,143 * Unrealized losses are reported through Accumulated deferred fuel on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. The following table quantifies the significant unobservable inputs used in developing the fair value of Level 3 positions for Cleco and Cleco Power at September 30, 2024, and December 31, 2023: FAIR VALUE VALUATION TECHNIQUE SIGNIFICANT UNOBSERVABLE INPUTS INPUT/RANGE (THOUSANDS, EXCEPT FORWARD PRICE RANGE) ASSETS LIABILITIES LOW (1) HIGH (1) WEIGHTED AVERAGE (2) FTRs at Sept. 30, 2024 $ 2,753 $ 369 RTO auction pricing FTR price - per MWh $ (5.52) $ 8.68 $ 0.22 FTRs at Dec. 31, 2023 $ 3,087 $ 781 RTO auction pricing FTR price - per MWh $ (3.51) $ 7.07 $ 0.24 (1) The low and high prices reflect the lowest and highest values of all single point-to-point FTRs and not the range of aggregate price changes. (2) The weighted average reflects the market price and volume of each commodity weighted by the total volume of commodities. Natural Gas Derivatives Cleco may enter into physical and financial fixed price forward or options contracts that financially settle or are physically delivered at a future date. Management has not elected to apply hedge accounting to these contracts as allowed under applicable accounting standards. Cleco Power’s natural gas derivative contracts are marked-to-market with the resulting unrealized gain or loss recorded as a component of Accumulated deferred fuel on the balance sheet. At settlement, realized gains or losses are included in Cleco Power’s FAC and reflected on customer’s bills as a component of the fuel charge. Prior to the closing of the Cleco Cajun Divestiture, Cleco Cajun’s unrealized gains or losses as well as realized gains or losses at settlement were recorded on the income statements as a component of fuel expense. After the closing of the Cleco Cajun Divestiture in June 2024, all of Cleco Cajun’s natural gas derivative contracts were liquidated. Upon liquidation, a $6.4 million gain was recorded in Cleco’s Condensed Consolidated Statements of Income as a component of fuel expense. Fair Value Measurements on a Nonrecurring Basis The following tables summarize the carrying value and estimated market value of Cleco’s and Cleco Power’s financial instruments not measured at fair value on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets: Cleco AT SEPT. 30, 2024 AT DEC. 31, 2023 (THOUSANDS) CARRYING VALUE * FAIR VALUE CARRYING VALUE * FAIR VALUE Long-term debt $ 3,148,776 $ 3,027,874 $ 3,400,293 $ 3,177,654 * The carrying value of long-term debt does not include deferred issuance costs of $12.4 million at September 30, 2024, and $14.2 million at December 31, 2023. Cleco Power AT SEPT. 30, 2024 AT DEC. 31, 2023 (THOUSANDS) CARRYING VALUE * FAIR VALUE CARRYING VALUE * FAIR VALUE Long-term debt $ 1,871,983 $ 1,913,692 $ 1,886,248 $ 1,867,559 * The carrying value of long-term debt does not include deferred issuance costs of $10.5 million at September 30, 2024, and $11.5 million at December 31, 2023. In order to fund capital requirements, Cleco may issue fixed and variable rate long-term debt with various tenors. The fair value of this class fluctuates as the market interest rates for fixed and variable rate debt with similar tenors and credit ratings change. The fair value of the debt could also change from period to period due to changes in the credit rating of the Cleco entity by which the debt was issued. The fair value of long-term debt is classified as Level 2 in the fair value hierarchy. Concentrations of Credit Risk At September 30, 2024, and December 31, 2023, Cleco and Cleco Power were exposed to concentrations of credit risk through their short-term investments classified as cash equivalents and restricted cash equivalents. If the short-term investments failed to perform under the terms of the investments, Cleco and Cleco Power could be exposed to a loss of the invested amounts. Collateral on these types of investments is not required. In order to optimize interest income and minimize risk, cash is invested primarily in short-term securities issued by the U.S. government and money market mutual funds to maintain liquidity and achieve the goal of a net asset value of a dollar. When Cleco enters into commodity derivative or physical commodity transactions directly with market participants, Cleco may be exposed to counterparty credit risk. Cleco is exposed to counterparty credit risk when a counterparty fails to meet their financial obligations causing Cleco to potentially incur replacement cost losses. Cleco enters into long-form contracts and master agreements with counterparties that govern the risk of counterparty credit default and allow for collateralization above prenegotiated thresholds to help mitigate potential losses. Alternatively, Cleco may be required to provide credit support with respect to bilateral transactions and contracts that Cleco has entered into or may enter into in the future. The amount of credit support required may change based on margining formulas, changes in credit agency ratings, or liquidity ratios.

Debt	Note 8 — Debt On May 17, 2024, Cleco Holdings entered into a $175.0 million revolving credit agreement. This agreement replaced Cleco Holdings’ existing revolving credit agreement and matures on May 17, 2029. Under this agreement, Cleco Holdings is required to maintain total indebtedness, not including securitization indebtedness, less than or equal to 65% of total capitalization. The borrowing costs under Cleco Holdings’ revolving credit agreement are currently equal to SOFR plus 1.725% or ABR plus 0.625%, plus commitment fees of 0.275% on the unused portion of the facility. If Cleco Holdings’ credit ratings were to be downgraded one level by the credit rating agencies, Cleco Holdings may be required to pay higher commitment fees and additional interest of 0.05%. At September 30, 2024, Cleco Holdings had no borrowings outstanding under its revolving credit facility. In addition, on May 17, 2024, Cleco Power entered into a $300.0 million revolving credit agreement and a $125.0 million term loan agreement. The revolving credit agreement replaced Cleco Power’s existing revolving credit agreement and matures on May 17, 2029. The term loan agreement replaced Cleco Power’s existing term loan agreement and matures on May 17, 2025. Under these agreements, Cleco Power is required to maintain total indebtedness, not including securitization indebtedness, less than or equal to 65% for total capitalization. The borrowing costs under the revolving credit agreement are currently equal to SOFR plus 1.35% or ABR plus 0.25%, plus commitment fees of 0.15% on the unused portion of the facility. If Cleco Power’s credit ratings were to be downgraded one level by the credit rating agencies, Cleco Power may be required to pay higher commitment fees and additional interest of 0.025%. At September 30, 2024, Cleco Power had no borrowings outstanding under the revolving credit agreement. The term loan under the term loan agreement bears interest at a rate of SOFR plus 1.35% or ABR plus 0.25%. On April 26, 2024, Cleco Holdings repaid its $66.7 million term loan that was due on May 21, 2024. In addition, on June 4, 2024, Cleco Holdings redeemed its $165.0 million floating rate senior notes due on May 1, 2025. Cleco Power’s $50.0 million GO-Zone bonds have a mandatory tender in April 2025. This amount is reflected in long-term debt due within one year on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets at September 30, 2024. At September 30, 2024, and December 31, 2023, Cleco’s long-term debt and finance leases outstanding due within one year were $240.9 million and $256.8 million, respectively. The decrease of $15.9 million is primarily due to the repayment of Cleco Holdings’ $66.7 million term loan, partially offset by the reclassification of Cleco Power’s $50.0 million GO-Zone bonds with a mandatory tender in April 2025. At September 30, 2024, and December 31, 2023, Cleco Power’s long-term debt and finance leases outstanding due within one year was $240.9 million and $190.3 million, respectively. The increase of $50.6 million is primarily due to the reclassification of $50.0 million GO-Zone bonds with a mandatory tender in April 2025.

Retirement Benefits [Abstract]
Pension Plan and Employee Benefits	Note 9 — Pension Plan and Employee Benefits Pension Plan and Other Benefits Plan Employees hired before August 1, 2007, are covered by a non-contributory, defined benefit pension plan. Based on the funding assumptions at December 31, 2023, management estimates that pension contributions totaling $94.2 million will be required through 2028, of which $25.7 million is required in 2024. In April 2024 and July 2024, Cleco made payments of $3.5 million and $7.1 million, respectively, toward its 2024 contribution requirement. In July 2024, Cleco also made a $15.2 million required contribution payment towards the 2023 plan year. In June 2024, an amendment to the pension plan was executed allowing the transfer of the cash balance and pension liabilities to the Cleco Cajun Purchaser’s pension plan. This transfer was for the former Cleco Cajun employees that became employees of the Cleco Cajun Purchasers following the closing of the Cleco Cajun Divestiture. The transfer was completed in June 2024. Cleco’s retirees may be eligible to receive Other Benefits. Dependents of Cleco’s retirees may also be eligible to receive Other Benefits with the exception of life insurance benefits. The non-service components of net periodic pension and Other Benefits cost are included in Other income (expense), net within Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. The components of net periodic pension and Other Benefits cost for the three and nine months ended September 30, 2024, and 2023 were as follows: PENSION BENEFITS OTHER BENEFITS FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE THREE MONTHS ENDED SEPT. 30, (THOUSANDS) 2024 2023 2024 2023 Components of periodic benefit costs Service cost $ 1,114 $ 1,173 $ 475 $ 365 Interest cost 6,535 6,606 583 566 Expected return on plan assets (7,607) (7,386) — — Amortizations Net loss (gain) — — 156 (13) Net periodic benefit cost $ 42 $ 393 $ 1,214 $ 918 PENSION BENEFITS OTHER BENEFITS FOR THE NINE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2024 2023 2024 2023 Components of periodic benefit costs Service cost $ 3,490 $ 3,520 $ 1,375 $ 1,094 Interest cost 19,605 19,817 1,750 1,698 Expected return on plan assets (22,821) (22,158) — — Amortizations Net loss (gain) — — 367 (39) Net periodic benefit cost $ 274 $ 1,179 $ 3,492 $ 2,753 Because Cleco Power is the pension plan sponsor and the related trust holds the assets, the net unfunded status of the pension plan is reflected at Cleco Power. The liability of Cleco’s other subsidiaries is transferred, with a like amount of assets, to Cleco Power monthly. The expense of the pension plan related to Cleco’s other subsidiaries for the three and nine months ended September 30, 2024, was $0.4 million and $1.3 million, respectively. The expense of the pension plan related to Cleco’s other subsidiaries for the three and nine months ended September 30, 2023, was $0.4 million and $1.2 million, respectively. The current and non-current portions of the pension benefits liability for Cleco and Cleco Power at September 30, 2024, and December 31, 2023, were as follows: (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Current $ 12,594 $ 25,685 Non-current $ 79,250 $ 91,638 Cleco Holdings is the plan sponsor for the Other Benefit plan. There are no assets set aside in a trust, and the liabilities are reported on the individual subsidiaries’ financial statements. The expense related to Other Benefits reflected in Cleco Power’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2024, was $1.1 million and $3.2 million, respectively. The expense related to Other Benefits reflected in Cleco Power’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2023, was $0.9 million and $2.6 million, respectively. The current and non-current portions of the Other Benefits liability for Cleco and Cleco Power at September 30, 2024, and December 31, 2023, were as follows: Cleco (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Current $ 5,235 $ 5,241 Non-current $ 41,012 $ 41,815 Cleco Power (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Current $ 4,480 $ 4,479 Non-current $ 31,893 $ 32,289 SERP Certain current and former Cleco officers are covered by SERP. Cleco does not fund the SERP liability but instead pays for current benefits out of cash available of the respective company of the officer. Because SERP is a non-qualified plan, Cleco has purchased life insurance policies on certain SERP participants as a mechanism to provide a source of funding. These policies are held in a rabbi trust formed by Cleco Power. The rabbi trust is the named beneficiary of the life insurance policies and, therefore, receives the proceeds upon the death of the insured participants. The life insurance policies may be used to reimburse Cleco for benefits paid from general funds, pay the SERP participants’ death benefits, or pay future SERP payments. Market conditions could have a significant impact on the cash surrender value of these life insurance policies. Because SERP is a non-qualified plan, the assets of the trust could be used to satisfy general creditors of Cleco Power in the event of insolvency.

Income Tax Disclosure [Abstract]
Income Taxes	Note 10 — Income Taxes Effective Tax Rates The following tables summarize the effective income tax rates from continuing operations for Cleco and Cleco Power for the three and nine months ended September 30, 2024, and 2023 : Cleco FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS 2024 2023 2024 2023 Effective tax rate (7.6) % (470.9) % (10.2) % 1,006.9 % Cleco Power FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS 2024 2023 2024 2023 Effective tax rate 10.1 % (0.6) % 9.2 % 2.6 % For Cleco and Cleco Power, the effective income tax rates for the three and nine months ended September 30, 2024, and 2023, were different than the federal statutory rate primarily due to the amortization of excess ADIT, the adjustment to record tax expense at the projected annual effective tax rate, flow through of state tax benefits, and state tax expense. Cleco’s effective tax rate for the three and nine months ended September 30, 2024, compared to the three and nine months ended September 30, 2023, was different primarily due to the amortization of excess ADIT, the adjustment to record tax expense at the projected annual effective tax rate, flow through of state tax benefits, and higher pre-tax book income in 2024 due to lower losses on gas-related derivative contracts at Cleco Cajun. Uncertain Tax Positions Cleco classifies all interest related to uncertain tax positions as a component of interest payable and interest expense. For the three and nine months ended September 30, 2024, and 2023, Cleco and Cleco Power had no interest expense related to uncertain tax positions. At September 30, 2024, and December 31, 2023, Cleco and Cleco Power had no liability for uncertain tax positions or interest payable related to uncertain tax positions. Income Tax Audits Cleco and Cleco Power are party to the consolidated income tax return filed by Cleco Group. Cleco Group participates in the IRS’s Compliance Assurance Process in which tax positions are examined and agreed upon prior to filing the federal tax return. While the statute of limitations remains open for tax years 2021, 2022, and 2023, the IRS has placed Cleco Group in the Bridge phase of the Compliance Assurance Process for the 2021 tax year. In this phase, the IRS will not accept any disclosures, conduct any reviews, or provide any assurances. These tax returns were filed consistent with the IRS’s review. The IRS has accepted Cleco Group’s application for the Compliance Assurance Process for the 2022 tax year and the Compliance Assurance Maintenance phase for the 2023 tax year. In this maintenance phase, the IRS typically will, at its discretion, reduce the level of its review of the tax year relative to the regular Compliance Assurance Process phase. The state income tax years 2021, 2022, and 2023 remain subject to examination by the Louisiana Department of Revenue. Cleco classifies income tax penalties as a component of other expense. For the three and nine months ended September 30, 2024, and 2023, no penalties were recognized.

Segment Reporting [Abstract]
Segment Disclosures	Note 11 — Segment Disclosures Segment disclosures are based on Cleco’s method of internal reporting, which disaggregates business units by first-tier subsidiary. Cleco’s segment structure and its allocation of corporate expenses were updated to reflect how management measures performance and allocates resources. Segment managers report periodically to Cleco’s CEO, who is Cleco’s chief operating decision maker, with discrete financial information and, at least quarterly, present discrete financial information to Cleco Holdings’ and, in the case of Cleco Power, Cleco Power’s Boards of Managers. The reportable segment prepares budgets that are presented to and approved by Cleco Holdings’ and, in the case of Cleco Power, Cleco Power’s Boards of Managers. The column shown as Other in the following tables includes the holding company, a shared services subsidiary, an investment subsidiary, discontinued operations, and Cleco Cajun’s natural gas derivatives. After the closing of the Cleco Cajun Divestiture, all of Cleco Cajun’s natural gas derivative contracts were liquidated. The financial results in the following tables are presented on an accrual basis. EBITDA is a key non-GAAP financial measure used by the CEO to assess the operating performance of Cleco’s segments. Management evaluates the performance of Cleco’s segments and allocates resources to it based on segment profit and the requirements to implement strategic initiatives and projects to meet current business objectives. EBITDA is defined as net income adjusted for interest, income taxes, depreciation, and amortization. Depreciation and amortization in the following tables includes amortization of intangible assets recorded for the fair value adjustment of wholesale power supply agreements as a result of the 2016 Merger. Material intercompany transactions occur on a regular basis. These intercompany transactions relate primarily to joint and common administrative support services.

Regulated Operations [Abstract]
Regulation and Rates	Note 12 — Regulation and Rates Dolet Hills Regulatory Refund Cleco Power is seeking recovery for stranded and decommissioning costs associated with the retirement of the Dolet Hills Power Station as well as deferred fuel and other mine-related closure costs. These costs were subject to a prudency review by the LPSC. On February 2, 2024, the ALJ released a final recommendation indicating a partial disallowance of the recovery of fuel costs and a refund of related costs previously recovered from customers. Management estimated that a loss resulting from a potential disallowance was probable, and as a result, Cleco Power accrued an estimated contingent loss of $58.7 million as of December 31, 2023. Cleco Power recorded an additional loss of $1.3 million as of March 31, 2024, as a result of the approval of an uncontested settlement by the LPSC on April 19, 2024. The settlement contains a provision for refunding to Cleco Power’s retail customers $20.0 million per year during each of the third quarters of 2024, 2025, and 2026 for a total refund of $60.0 million. Cleco Power has issued refunds for the third quarter of 2024. For more information about the settlement, see Note 14 — “ Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees — Litigation — LPSC Audits and Reviews — Dolet Hills Prudency Review.” FRP Prior to July 1, 2024, Cleco Power’s annual retail earnings were subject to an FRP approved by the LPSC in June 2021. The prior FRP allowed Cleco Power to earn a target ROE of 9.5%, while providing the opportunity to earn up to 10.0%. Additionally, 60.0% of retail earnings between 10.0% and 10.5%, and all retail earnings over 10.5%, were required to be refunded to customers. On June 19, 2024, the LPSC approved Cleco Power’s new retail rate plan. Effective July 1, 2024, under the terms of the new FRP, Cleco Power is allowed to earn a target ROE of 9.7%, while providing the opportunity to earn up to 10.3%. Additionally, 60% of retail earnings between 10.3% and 10.9%, and all retail earnings over 10.9%, are required to be refunded to customers. Cleco Power’s next base rate case is required to be filed with the LPSC on or before June 30, 2026. The amount of credits due to customers, if any, is determined by Cleco Power’s monitoring report, which is filed with the LPSC annually. Additionally, as approved in Cleco Power’s FRP, a residential revenue decoupling mechanism was implemented through its infrastructure and incremental cost recovery rider that provides a charge or credit to residential customers for any under or over collection of residential base revenue. For more information on the regulatory liability established for the revenue decoupling mechanism, see Note 5 — “ Regulatory Assets and Liabilities — Residential Revenue Decoupling.” On May 22, 2024, the LPSC approved Cleco Power’s monitoring report for the 12-month period ended June 30, 2023, indicating no material findings and no refund to Cleco Power’s retail customers. On October 31, 2024, Cleco Power filed its monitoring report for the 12-month period ending June 30, 2024, indicating no refund to Cleco Power’s retail customers. Other Deferred Costs Cleco Power defers other costs that it believes are prudently incurred and probable of recovery from its retail customers. These costs are recorded in Other deferred charges on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. On June 19, 2024, the LPSC approved for Cleco Power to recover through its new rates, effective on July 1, 2024, costs associated with Cleco Power’s rate case, IRP, and storm preparation. As a result, $3.8 million was reclassified to Other regulatory assets on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. At September 30, 2024, Cleco Power had $4.6 million recorded for deferred costs it anticipates to recover from its customers, subject to approval by the LPSC. TCJA Cleco Power’s retail customers are continuing to receive bill credits resulting from the TCJA. Beginning in July 2021, under Cleco Power’s prior retail rate plan, retail customers received approximately $2.5 million in monthly bill credits for the target retail portion of the unprotected excess ADIT. At June 30, 2024, all amounts for the unprotected excess ADIT had been returned to retail customers. The retail portion of the protected excess ADIT will be credited until the full amount of the protected excess ADIT has been returned to Cleco Power’s customers through bill credits. At September 30, 2024, Cleco Power had $191.3 million accrued for the excess ADIT, of which $7.0 million is reflected in current regulatory liabilities. Teche Unit 3 In May 2023, Cleco Power filed an Attachment Y with MISO requesting retirement of Teche Unit 3, barring any violations of specific applicable reliability standards. In January 2024, Cleco Power filed a notice with the LPSC to retire Teche Unit 3, and on June 1, 2024, Teche Unit 3 was retired.

Variable Interest Entities	Sep. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 13 — Variable Interest Entities Cleco Securitization I Cleco Securitization I is a special-purpose, wholly owned subsidiary of Cleco Power that was formed for the purpose of issuing storm recovery bonds to finance the securitization of Storm Recovery Property at Cleco Power. Cleco Securitization I’s assets cannot be used to settle Cleco Power’s obligations and the holders of the storm recovery bonds have no recourse against Cleco Power. Because Cleco Securitization I’s equity at risk is less than 1% of its total assets, it is considered to be a variable interest entity. Through its equity ownership interest and role as servicer, Cleco Power has the power to direct the most significant financial and operating activities of Cleco Securitization I, including billing, collections, and remittance of retail customer cash receipts to enable Cleco Securitization I to pay the principal and interest payments on the storm recovery bonds. Cleco Power also has the obligation to absorb losses up to its equity investment and rights to receive returns from Cleco Securitization I. Therefore, management has determined that Cleco Power is the primary beneficiary of Cleco Securitization I, and as a result, Cleco Securitization I is included in the consolidated financial statements of Cleco Power. No gain or loss was recognized upon initial consolidation. The following table summarizes the impact of Cleco Securitization I on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets: (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Restricted cash - current $ 7,537 $ 15,818 Accounts receivable - affiliate 3,398 3,492 Intangible asset - securitization 388,135 398,658 Total assets $ 399,070 $ 417,968 Long-term debt due within one year $ 15,087 $ 14,499 Accounts payable - affiliate 33 176 Interest accrued 1,499 6,191 Long-term debt, net 380,318 394,944 Total liabilities 396,937 415,810 Member’s equity 2,133 2,158 Total liabilities and member’s equity $ 399,070 $ 417,968 The following table summarizes the impact of Cleco Securitization I on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2024 2023 2024 2023 Operating revenue $ 8,776 $ 9,946 $ 24,578 $ 25,329 Operating expenses (4,271) (5,264) (10,876) (11,017) Interest income 214 188 557 430 Interest charges, net (4,694) (4,845) (14,185) (14,668) Income before taxes $ 25 $ 25 $ 74 $ 74 Oxbow Cleco and Cleco Power apply the equity method of accounting to report the investment in Oxbow in the consolidated financial statements. Under the equity method, the assets and liabilities of this entity are reported as Equity investment in investee on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. The revenue and expenses (excluding income taxes) of this entity are netted and reported as equity income or loss from investees on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. Oxbow is owned 50% by Cleco Power and 50% by SWEPCO. Cleco Power is not the primary beneficiary because it shares the power to control Oxbow’s significant activities with SWEPCO.

Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees	Note 14 — Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees Litigation Gulf Coast Spinning In September 2015, a potential customer sued Cleco for failure to fully perform an alleged verbal agreement to lend or otherwise fund its startup costs of $6.5 million. Gulf Coast Spinning Company, LLC (Gulf Coast), the primary plaintiff, alleges that Cleco promised to assist it in raising approximately $60.0 million, which Gulf Coast needed to construct a cotton spinning facility near Bunkie, Louisiana (the Bunkie project). According to the petition filed by Gulf Coast in the 12 th Judicial District Court for Avoyelles Parish, Louisiana, Cleco made such promises of funding assistance in order to cultivate a new industrial electric customer which would increase its revenues under a power supply agreement that it executed with Gulf Coast. Gulf Coast seeks unspecified damages arising from its inability to raise sufficient funds to complete the project, including lost profits. Cleco filed an Exception of No Cause of Action arguing that the case should be dismissed. The 12 th Judicial District Court denied Cleco’s exception in December 2015, after considering briefs and arguments. In January 2016, Cleco appealed the 12 th Judicial District Court’s denial of its exception by filing with the Third Circuit Court of Appeal. In June 2016, the Third Circuit Court of Appeal denied the request to have the case dismissed. In July 2016, Cleco filed a writ to the Louisiana Supreme Court seeking a review of the 12 th Judicial District Court’s denial of Cleco’s exception. In November 2016, the Louisiana Supreme Court denied Cleco’s writ application. In February 2016, the parties agreed to a stay of all proceedings pending discussions concerning settlement. In May 2016, the 12 th Judicial District Court lifted the stay at the request of Gulf Coast. The parties are currently participating in discovery. Diversified Lands loaned $2.0 million to Gulf Coast for the Bunkie project. The loan was secured by a mortgage on the Bunkie project site. Diversified Lands foreclosed on the Bunkie property in February 2020 and has also asserted claims personally against the former owner of Gulf Coast. These claims are based on contracts and credit documents executed by Gulf Coast, the obligations and performance of which were personally guaranteed by the former owner of Gulf Coast. Diversified Lands is seeking recovery of the indebtedness still owed by Gulf Coast to Diversified Lands following the February 2020 foreclosure. This action has been consolidated with the litigation filed by Gulf Coast in the 12 th Judicial District Court for Avoyelles Parish, Louisiana. Discovery is ongoing and the trial date has been scheduled for April 2025. Cleco believes all allegations made by Gulf Coast are contradicted by the written documents executed by Gulf Coast, are otherwise without merit, and that it has substantial meritorious defenses to the claims alleged by Gulf Coast. Dispute with Saulsbury Industries In October 2018, Cleco Power sued Saulsbury Industries, Inc., the former general contractor for the St. Mary Clean Energy Center project, seeking damages for Saulsbury Industries, Inc.’s failure to complete the St. Mary Clean Energy Center project on time and for costs incurred by Cleco Power in hiring a replacement general contractor. The action was filed in the Ninth Judicial District Court for Rapides Parish. Saulsbury Industries, Inc. removed the case to the U.S. District Court for the Western District of Louisiana, in March 2019. In September 2020, Cabot Corporation was allowed to join the case pending in the Ninth Judicial District Court for Rapides Parish. In January 2019, Cleco Power was served with a summons in Saulsbury Industries, Inc. v. Cabot Corporation and Cleco Power LLC , in the U.S. District Court for the Western District of Louisiana. Saulsbury Industries, Inc. alleged that Cleco Power and Cabot Corporation caused delays in the St. Mary Clean Energy Center project, resulting in alleged impacts to Saulsbury Industries, Inc.’s direct and indirect costs. In June 2019, Cleco Power and Cabot Corporation each filed separate motions to dismiss. In October 2019, the District Court denied Cleco Power’s motion as premature and ruled that Saulsbury Industries, Inc. had six weeks to conduct discovery on specified jurisdictional issues. The Magistrate Judge presiding over the Western District of Louisiana consolidated cases issued a report and recommendation to the District Judge that the case instituted by Saulsbury Industries, Inc. be dismissed without prejudice and the case initiated by Cleco Power be remanded to the Ninth Judicial District Court for Rapides Parish. Saulsbury Industries, Inc. did not oppose the Magistrate Judge’s report and recommendation, and the District Judge issued a ruling that adopted the Magistrate Judge’s report and recommendation, which included reasoning consistent with Cleco Power’s arguments. Thus, the federal consolidated cases are now closed. In October 2019, Cleco Power was served with a summons in Saulsbury Industries, Inc. v. Cabot Corporation and Cleco Power LLC in the 16 th Judicial District Court for St. Mary Parish. Saulsbury Industries, Inc. asserted the same claim as the Western District litigation and further asserts claims for payment on an open account. In December 2019, Cleco Power moved to stay the case, arguing that the Rapides Parish suit should proceed. In February 2020, the court granted Cleco Power’s motion. The 16 th Judicial District Court for the St. Mary Parish case held a hearing in October 2020, and the judge granted Cleco Power’s declinatory exceptions of lis pendens. Thus, the St. Mary’s Parish case has been dismissed. Saulsbury appealed this decision. In May 2022, the Court of Appeal, First Circuit, ruled in favor of Cleco Power and affirmed the decision of the 16 th Judicial District Court for St. Mary Parish with respect to Cleco Power. However, the First Circuit Court reversed the 16 th Judicial District Court for St. Mary Parish’s decision dismissing Cabot Corporation from the St. Mary Parish case. All parties filed applications for rehearing, which were denied in June 2022. Cabot Corporation applied for review by the Louisiana Supreme Court of the portion of the First Circuit Court’s ruling that denied Cabot Corporation’s exception seeking dismissal from the St. Mary Parish litigation. In November 2022, the Louisiana Supreme Court rendered a decision in favor of Cabot Corporation. The Louisiana Supreme Court’s decision reversed the First Circuit Court’s decision and reinstated the decision of the 16 th Judicial District Court granting Cabot Corporation’s declinatory exceptions of lis pendens. The St. Mary Parish case has been dismissed in full. The stay was lifted in the Rapides Parish case and the Rapides Parish case is proceeding. Cleco Power and Saulsbury are currently participating in discovery. LPSC Audits and Reviews Fuel Audits Generally, Cleco Power’s cost of fuel used for electric generation and the cost of purchased power are recovered through the LPSC-established FAC that enables Cleco Power to pass on to its customers substantially all such expenses. Recovery of FAC costs is subject to periodic fuel audits by the LPSC, which are performed at least every other year. In January 2023, Cleco Power received a notice of audit from the LPSC for the period of January 2020 to December 2022. The total amount of fuel expense included in the audit is $1.10 billion. Cleco Power has responded to multiple sets of LPSC data requests. Cleco Power has FAC filings for January 2023 and thereafter that remain subject to audit. Management is unable to predict or give a reasonable estimate of the possible range of the disallowance, if any, related to these filings. Historically, the disallowances have not been material. If a disallowance of fuel cost is ordered resulting in a refund, it could have a material adverse effect on the results of operations, financial condition, or cash flows of the Registrants. Environmental Audit In 2009, the LPSC approved Cleco Power to recover certain costs of environmental compliance through an EAC. The costs eligible for recovery are those for prudently incurred air emissions credits associated with complying with federal, state, and local air emission regulations that apply to the generation of electricity reduced by the sale of such allowances. Also eligible for recovery are variable emission mitigation costs, which are the costs of reagents such as ammonia and limestone that are a part of the fuel mix used to reduce air emissions, among other things. Cleco Power has EAC filings for January 2023 and thereafter that remain subject to audit. Management is unable to predict or give a reasonable estimate of the possible range of the disallowance, if any, related to these filings. Historically, the disallowances have not been material. If a disallowance of environmental cost is ordered resulting in a refund to Cleco Power’s customers, any such refund could have a material adverse effect on the results of operations, financial condition, or cash flows of the Registrants. Cleco Power incurs environmental compliance expenses for reagents associated with the compliance standards of MATS. These expenses are also eligible for recovery through Cleco Power’s EAC and are subject to periodic review by the LPSC. In May 2020, the EPA finalized a rule that concluded that it is not appropriate and necessary to regulate hazardous air pollutants from coal- and oil-fired electric generating units. The EPA also determined that the results of its risk and technology review did not require any revisions to the emissions standards. Several petitions for review of the rule’s findings were filed between May and July 2020 in the D.C. Circuit Court of Appeals. In January 2021, the Presidential Administration issued an executive order that specifically directed the EPA to consider issuing a proposed rule to suspend, revise, or rescind the rule. The EPA determined the most environmentally protective course is to implement the rules in the executive order. In March 2023, the EPA published in the Federal Register a final rule that reinstates the April 2016 finding that it is appropriate and necessary to regulate hazardous air pollutants from coal and oil-fired electric generating units through MATS. The EPA published a final rule in the Federal Register on May 7, 2024, that reconsiders the risk and technology review that took place in 2020. The rule lowers the emission limit for filterable particulate on coal-fired EGUs. The rule also requires installation of continuous emission monitors for particulate on the units. The compliance deadlines are in July 2027. At September 30, 2024, Cleco is in compliance with the MATS regulation and does not expect MATS to materially impact its environmental strategy. Energy Efficiency Audit In 2013, the LPSC issued a General Order adopting rules promoting energy efficiency programs. Cleco Power began participating in energy efficiency programs in November 2014. Through an approved rate tariff, Cleco Power recovered $8.5 million and $6.8 million for the 2022 and 2021 program years, respectively. In May 2024, the LPSC approved the audit report for program years 2021 and 2022, which indicated no material findings. On January 24, 2024, the LPSC voted to shift control of energy efficiency programs from utilities to an independent, third-party administrator selected by and accountable to the LPSC. This action will remove the provision whereby utilities were allowed to recover any lost revenues associated with unsold electricity. Cleco Power is subject to audits for program years 2023 and thereafter until the time these programs are shifted to the third-party administrator, which is expected in January 2026. Dolet Hills Prudency Review Cleco Power is seeking recovery for stranded and decommissioning costs associated with the retirement of the Dolet Hills Power Station as well as deferred fuel and other mine-related closure costs. On February 2, 2024, the ALJ released a final recommendation indicating a partial disallowance of the recovery of fuel costs and a refund of related costs previously recovered from customers. Management estimated that a loss resulting from a potential disallowance was probable, and as a result, an estimated contingent loss of $58.7 million was accrued in provision for rate refund as of December 31, 2023. On April 19, 2024, the LPSC approved an uncontested settlement containing the following provisions: • a $40.0 million reduction in the regulatory asset associated with the Dolet Hills Power Station, • refunding $20.0 million per year to Cleco Power’s retail customers as a credit to their bills during the third quarters of 2024, 2025, and 2026 for a total of $60.0 million, and • allowing securitization of $305.0 million. If the securitization is not complete by September 1, 2024, Cleco Power is allowed to accrue a carrying charge through the earlier of the completion of the securitization or January 31, 2025. As a result of the settlement, the following was recorded in Cleco’s and Cleco Power’s Condensed Consolidated Financial Statements as of March 31, 2024: • a $40.0 million reduction in regulatory assets with an offsetting increase recorded as depreciation expense and • a $1.3 million increase in the provision for rate refund and electric customer credits. During the third quarter of 2024, $20.0 million was refunded to Cleco Power’s retail customers as a credit to their bills in accordance with the settlement, as previously discussed. On May 17, 2024, Cleco Power filed an application with the LPSC for a financing order authorizing the securitization. Management anticipates the securitization to close by the end of March 2025. Other Cleco is involved in various litigation matters, including regulatory, environmental, and administrative proceedings before various courts, regulatory commissions, arbitrators, and governmental agencies regarding matters arising in the ordinary course of business. The liability Cleco may ultimately incur with respect to any one of these matters may be in excess of amounts currently accrued. Management regularly analyzes current information and, as of September 30, 2024, believes the probable and reasonably estimable liabilities based on the eventual disposition of these matters for Cleco and Cleco Power are $11.9 million and $11.3 million, respectively. Cleco and Cleco Power have accrued these amounts. Off-Balance Sheet Commitments and Guarantees Cleco Holdings and Cleco Power have entered into various off-balance sheet commitments, in the form of guarantees and standby letters of credit, in order to facilitate their activities and the activities of Cleco Holdings’ subsidiaries and equity investees (affiliates). Cleco Holdings and Cleco Power have also agreed to contractual terms that require the Registrants to pay third parties if certain triggering events occur. These contractual terms generally are defined as guarantees. Cleco Holdings entered into these off-balance sheet commitments in order to entice desired counterparties to contract with its affiliates by providing some measure of credit assurance to the counterparty in the event Cleco’s affiliates do not fulfill certain contractual obligations. If Cleco Holdings had not provided the off-balance sheet commitments, the desired counterparties may not have contracted with Cleco’s affiliates or may have contracted with them at terms less favorable to its affiliates. The off-balance sheet commitments are not recognized on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets because management has determined that Cleco’s and Cleco Power’s affiliates are able to perform the obligations under their contracts and that it is not probable that payments by Cleco or Cleco Power will be required. Cleco Holdings provided guarantees and indemnities to Entergy Louisiana and Entergy Gulf States as a result of the sale of the Perryville generation facility in 2005. The remaining indemnities relate to environmental matters that may have been present prior to closing. These remaining indemnities have no time limitations. The maximum amount of the potential payment to Entergy Louisiana and Entergy Gulf States is $42.4 million. Management does not expect to be required to pay Entergy Louisiana and Entergy Gulf States under these guarantees. On behalf of Acadia, Cleco Holdings provided guarantees and indemnities as a result of the sales of Acadia Unit 1 to Cleco Power and Acadia Unit 2 to Entergy Louisiana in 2010 and 2011, respectively. The remaining indemnities relate to the fundamental organizational structure of Acadia. These remaining indemnities have no time limitations or maximum potential future payments. Management does not expect to be required to pay Cleco Power or Entergy Louisiana under these guarantees. Cleco Holdings provided indemnities to Cleco Power as a result of the transfer of Coughlin to Cleco Power in March 2014. Cleco Power also provided indemnities to Cleco Holdings as a result of the transfer of Coughlin to Cleco Power. The maximum amount of the potential payment to Cleco Power and Cleco Holdings, for their respective indemnities is $40.0 million, except for indemnities relating to the fundamental organizational structure of each respective entity, of which the maximum amount is $400.0 million. Management does not expect to be required to make any payments under these indemnities. As part of the Amended Lignite Mining Agreement, Cleco Power and SWEPCO, joint owners of the Dolet Hills Power Station, have agreed to pay the loan and lease principal obligations of the lignite miner, DHLC, when due if DHLC does not have sufficient funds or credit to pay. Any amounts projected to be paid would be based on the forecasted loan and lease obligations to be incurred by DHLC, primarily for reclamation obligations. As of September 30, 2024, Cleco Power does not expect any payments to be made under this guarantee. Cleco Power has the right to dispute the incurrence of such loan and lease obligations through the review of the mining reclamation plan before the incurrence of such obligations. The Amended Lignite Mining Agreement does not affect the amount the Registrants can borrow under their credit facilities. Cleco has letters of credit to MISO pursuant to energy market requirements. The letters of credit automatically renew each year and have no impact on Cleco Holdings’ or Cleco Power’s revolving credit facility. Generally, neither Cleco Holdings nor Cleco Power has recourse that would enable them to recover amounts paid under their guarantee or indemnification obligations. There are no assets held as collateral for third parties that either Cleco Holdings or Cleco Power could obtain and liquidate to recover amounts paid pursuant to the guarantees or indemnification obligations. Other Commitments Cleco has accrued for liabilities related to third parties, employee medical benefits, and AROs. In April 2015, the EPA published a final rule in the Federal Register for regulating the disposal and management of CCRs from coal-fired power plants (CCR Rule). In August 2018, the D.C. Court of Appeals vacated several requirements in the CCR regulation, which included eliminating the previous acceptability of compacted clay material as a liner for impoundments. As a result, in August 2020, the EPA published a final rule in the Federal Register that would set deadlines for costly modifications including retrofitting of clay-lined impoundments with compliant liners or closure of the impoundments. In November 2020, demonstrations were submitted to the EPA specifying its intended course of action for the ash disposal facilities at Rodemacher Unit 2 and the Dolet Hills Power Station in order to comply with the final CCR Rule. In January 2022, Cleco Power received communication from the EPA that the demonstrations had been deemed complete. Cleco Power withdrew the Dolet Hills demonstration due to the cessation of receiving waste. The remaining demonstration is still subject to EPA approval based on pending technical review. On May 8, 2024, the EPA published a final rule in the Federal Register that expands the scope of units regulated under the CCR regulations to include inactive surface impoundments at inactive generating facilities that ceased operations prior to October 19, 2015. None of these impoundments exist at Cleco’s facilities. The rule also regulates CCR Management Units (MUs), which includes non-containerized accumulations of CCR on the land at facilities otherwise subject to federal CCR regulations. The final regulation mandates the conducting of facility evaluations at such facilities after the effective date of the rule to determine if MUs are present. For any identified MUs of a particular size, the regulation would require evaluating any impacts on groundwater along with planning for closure of any identified CCR MU sites. Cleco does not expect this final rule to have a material financial impact on its generating units and environmental obligations. Risks and Uncertainties Cleco could be subject to possible adverse consequences if Cleco’s counterparties fail to perform their obligations or if Cleco or its affiliates are not in compliance with loan agreements or bond indentures. Access to capital markets is a significant source of funding for both short- and long-term capital requirements not satisfied by operating cash flows. Changes in the regulatory environment or market forces could cause Cleco to determine its assets have suffered an other-than-temporary decline in value, whereby an impairment would be required, and Cleco’s financial condition could be materially adversely affected.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets and Goodwill	Note 16 — Intangible Assets and Goodwill Securitized Intangible Asset On June 22, 2022, Cleco Securitization I acquired the Storm Recovery Property from Cleco Power for a purchase price of $415.9 million. The Storm Recovery Property is classified as a securitized intangible asset on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. This securitized intangible asset is being amortized ratably each period consistent with actual collections of the asset’s portion of the revenue requirement billed to Cleco Power’s customers. At the end of its life, this securitized intangible asset will have no residual value. Amortization is included in Depreciation and amortization on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. The following table presents the amortization expense recognized during the three and nine months ended September 30, 2024, and 2023: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2024 2023 2024 2023 Amortization expense Storm Recovery Property intangible asset $ 4,176 $ 5,127 $ 10,523 $ 10,679 The following table summarizes the balance of the securitized intangible asset subject to amortization included on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets: (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Storm Recovery Property intangible asset $ 415,946 $ 415,946 Accumulated amortization (27,811) (17,288) Net securitized intangible asset subject to amortization $ 388,135 $ 398,658 Other Intangible Assets As a result of the 2016 Merger, fair value adjustments were recorded on Cleco’s Condensed Consolidated Balance Sheet for the valuation of finite intangible assets relating to long-term wholesale power supply agreements. At the end of their lives, these power supply agreement intangible assets will have no residual value. At September 30, 2024, Cleco had one remaining power supply agreement intangible asset being amortized over the estimated life of its contract of 19 years, and the amortization is included in Electric operations on Cleco’s Condensed Consolidated Statements of Income. The following table presents the amortization expense recognized during the three and nine months ended September 30, 2024, and 2023: Cleco FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2024 2023 2024 2023 Amortization expense Power supply agreements $ 186 $ 2,323 $ 2,695 $ 7,131 The following table summarizes the balance of other intangible assets subject to amortization included in Cleco’s Condensed Consolidated Balance Sheets: Cleco (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Power supply agreements $ 14,238 $ 85,104 Accumulated amortization (6,300) (74,471) Net other intangible assets subject to amortization $ 7,938 $ 10,633 Goodwill On April 13, 2016, in connection with the completion of the 2016 Merger, Cleco recognized goodwill of $1.49 billion. Management assigned the recognized goodwill to the Cleco Power reporting unit. Goodwill is required to be tested for impairment at the reporting unit level on an annual basis or whenever events or circumstances indicate that the value of goodwill may be impaired. In performing the impairment test, Cleco compares the fair value of the reporting unit to its carrying value including goodwill. If the carrying value including goodwill were to exceed the fair value of a reporting unit, an impairment loss would be recognized. A goodwill impairment loss is measured as the amount by which a reporting unit’s carrying value exceeds fair value, not to exceed the carrying amount of goodwill. Cleco estimates the reporting unit’s fair value using a weighted combination of the income approach, which estimates fair value based on discounted cash flows, and the market approach, which estimates fair value based on market comparables within the utility and energy industries. The income approach cash flow valuations involve a number of estimates that require broad assumptions and significant judgment by management regarding future performance, including estimation of future cash flows related to capital expenditures, the weighted average cost of capital or discount rate and the assumed long-term growth rate approach, which incorporates management's assumptions regarding sustainable long-term growth. The market approach includes significant assumptions around the implied market multiples for certain peer companies. Management selects comparable peers based on each peer’s primary business mix, operations, and market capitalization compared to the applicable reporting unit and calculates implied market multiples based on available projected earnings guidance and peer company market values as of the test date. Cleco performs an annual impairment test each August. In between annual tests, Cleco monitors its estimates and assumptions regarding estimated future cash flows, including the impact of movements in market indicators in future quarters, and will update the impairment analyses if a triggering event occurs. While Cleco believes the assumptions are reasonable, actual results may differ from projections. To the extent cash flows, long-term growth rates, U.S. Treasury rates, or other factors outside of Cleco’s control may impact Cleco’s projected results, Cleco may be required to reduce all or a portion of the carrying value of goodwill. Cleco conducted its 2024 annual impairment test using an August 1, 2024, measurement date and determined that the estimated fair value of the Cleco Power reporting unit exceeded its carrying value, and no impairment existed.

Storm Restoration	Sep. 30, 2024
Risks and Uncertainties [Abstract]
Storm Restoration	Note 18 — Storm Restoration During April and May 2024, Cleco Power’s service territory sustained damage in multiple severe weather events. Total storm restoration costs related to these events were approximately $14.2 million. On September 11, 2024, Hurricane Francine made landfall in southeast Louisiana as a Category 2 storm, causing power outages for approximately 37,000 of Cleco Power’s electric customers. By September 14, 2024, power was restored to all affected customers. Cleco Power’s total storm restoration costs related to this weather event is estimated to be between $18.0 million and $20.0 million. On October 8, 2024, Cleco Power made a filing with the LPSC seeking approval to withdraw storm restoration costs associated with the April 2024 storm, as well as costs associated with other storm events that occurred since December 2022, from the storm reserve. This request is currently under review by the LPSC. Management is assessing the accumulated restoration costs for Hurricane Francine as well as other storms that occurred in 2024 and anticipates filing an additional application seeking approval for withdrawal of these costs from the restricted storm reserve in 2025. For more information on the storm reserve, see Note 5 — “Regulatory Assets and Liabilities — Storm Reserves.”

Property, Plant and Equipment [Abstract]
Property, Plant and Equipment	Note 19 — Property, Plant, and Equipment In April 2022, Cleco Power announced Project Diamond Vault, a proposed project with the goal of reducing up to 95% of carbon dioxide emissions from Madison Unit 3 through various possible carbon capture and sequestration technologies. Development efforts using an amine-based carbon capture technology began in 2022, and a $9.0 million congressional appropriation was secured to help offset the costs associated with a related Feasibility study, a Pre-FEED study, and a FEED study. Both the related Feasibility study and the Pre-FEED study have been completed. The FEED study, which focused on the use of this amine-based carbon capture technology began in April 2024. Due to increases in the estimated investment required as well as the current economic and financing environment, Cleco Power’s management decided to discontinue the current FEED study and transition to evaluate other potential carbon capture and sequestration technologies or alternatives to decarbonize Madison Unit 3, including fuel switching technology. As of September 30, 2024, Cleco Power has incurred a total of $18.2 million related to Project Diamond Vault, of which Cleco Power has received $5.9 million from a congressional appropriation and expects to receive an additional $1.0 million to offset these costs. As of June 30, 2024, Cleco Power expensed $10.8 million of previously deferred project costs due to the uncertainty of recoverability. Given that the unique nature of these project costs did not relate to Cleco’s core operations, these costs were removed from Construction work in progress on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets and expensed to Other expense, net on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. As of September 30, 2024, Cleco Power incurred an additional $0.5 million of project costs and expensed these costs to Other expense, net on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income.

Summary of Significant Accounting Policies (Policies)	Sep. 30, 2024
Accounting Policies [Abstract]
Discontinued Operations	In March 2023, Cleco Holdings’ management, with the support of its Board of Managers, committed to a plan of action for the disposition of the Cleco Cajun Sale Group. As a result, Cleco Holdings’ management determined that the criteria under GAAP for the Cleco Cajun Sale Group to be classified as held for sale were met, and the sale represents a strategic shift that will have a major effect on Cleco’s future operations and financial results. Therefore, the results of operations and financial position of the Cleco Cajun Sale Group have been presented as discontinued operations since March 31, 2023. On June 1, 2024, the Cleco Cajun Divestiture closed. For more information, see Note 3 — “Discontinued Operations.”
Principles of Consolidation	The accompanying condensed consolidated financial statements of Cleco include the accounts of Cleco Holdings and its majority-owned subsidiaries after elimination of intercompany accounts and transactions.
Basis of Presentation	The condensed consolidated financial statements of Cleco and Cleco Power have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. The year-end condensed consolidated balance sheet data was derived from audited financial statements and adjusted for discontinued operations. Because the interim condensed consolidated financial statements and the accompanying notes do not include all of the information and notes required by GAAP for annual financial statements, the condensed consolidated financial statements and other information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes in the Registrants’ Combined Annual Report on Form 10-K for the fiscal year ended December 31, 2023. These condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments that are necessary for a fair statement of the financial position and results of operations of Cleco and Cleco Power. Amounts reported in Cleco’s and Cleco Power’s interim financial statements are not necessarily indicative of amounts expected for the annual periods due to the effects of seasonal temperature variations on energy consumption, regulatory rulings, the timing of maintenance on electric generating units, changes in mark-to-market valuations, changing commodity prices, discrete income tax items, and other factors.
Restricted Cash and Cash Equivalents	Various agreements to which Cleco is subject contain covenants that restrict its use of cash. As certain provisions under these agreements are met, cash is transferred out of related escrow accounts and becomes available for its intended purposes and/or general corporate purposes.
Reserves for Credit Losses	Customer accounts receivable are recorded at the invoiced amount and do not bear interest. Customer accounts receivable are generally considered past due 20 days after the billing date. Cleco recognizes write-offs within the allowance for credit losses once all recovery methods have been exhausted. It is the policy of management to review accounts receivable and unbilled revenue monthly using a reserve matrix based on historical bad debt write-offs, as well as current and forecasted economic conditions, to establish a credit loss estimate. Management’s historical credit loss analysis included periods of economic recessions, natural disasters, and temporary changes to collection policies. Due to the critical necessity of electricity, these past events have not significantly impacted Cleco’s credit loss rates. Cleco’s credit losses at September 30, 2024, were within range of its historical credit loss analysis.
Recent Authoritative Guidance	In March 2023, FASB issued guidance that applies to leases between entities under common control. The guidance provides a practical expedient for determining whether an arrangement between entities under common control is a lease as well as the classification of the lease. In addition, the leasehold improvements amortization period is to be determined by the useful life to the common group rather than the term of the lease. The new guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Cleco has arrangements between entities under common control. The implementation of this guidance did not have a material impact on the results of operations, financial condition, or cash flows of the Registrants. In November 2023, FASB issued guidance to improve reportable segment disclosure requirements. The guidance enhances interim disclosure requirements, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss, provides new segment disclosure requirements for entities with a single reportable segment, and contains other disclosure requirements. Disclosure requirements include disclosing significant segment expenses by reportable segment if they are regularly provided to the chief operating decision maker and included in each reported measure of segment profit or loss. Disclosures are required on both an annual and an interim basis. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Management does not expect this guidance to have a significant impact on the results of operations, financial condition, or cash flows of the Registrants.
Regulatory Assets and Liabilities	Cleco Power recognizes an asset for certain costs capitalized or deferred for recovery from customers and recognizes a liability for amounts expected to be returned to customers or collected for future expected costs. Cleco Power records these assets and liabilities based on regulatory approval and management’s ongoing assessment that it is probable these items will be recovered or refunded through the ratemaking process. Under the current regulatory environment, Cleco Power believes these regulatory assets will be fully recoverable. If in the future, as a result of regulatory changes or competition, Cleco Power’s ability to recover these regulatory assets would no longer be probable, then to the extent that such regulatory assets were determined not to be recoverable, Cleco Power would be required to write-down such assets. In addition, potential deregulation of the industry, or possible future changes in the method of rate regulation of Cleco Power, could require discontinuance of the application of the authoritative guidance on regulated operations. The following table summarizes Cleco Power’s regulatory assets and liabilities: Cleco Power REMAINING RECOVERY PERIOD (YRS.)

The following table summarizes Cleco’s net regulatory assets and liabilities: Cleco (THOUSANDS) AT SEPT. 30, 2024 AT DEC. 31, 2023 Total Cleco Power regulatory assets, net $ 470,591 $ 454,213 2016 Merger adjustments (1) Fair value of long-term debt 91,794 97,345 Postretirement costs 7,958 9,448 Financing costs 6,302 6,560 Debt issuance costs 4,004 4,254 Total Cleco regulatory assets, net $ 580,649 $ 571,820 (1) Cleco regulatory assets include acquisition accounting adjustments as a result of the 2016 Merger. Deferred Lignite and Mine Closure Costs and Dolet Hills Power Station Closure Costs In 2020, Cleco Power and SWEPCO made a joint filing with the LPSC seeking authorization to close the Oxbow mine and to include and defer certain accelerated mine closing costs in fuel and related ratemaking treatment. In 2021, the LPSC approved the establishment of a regulatory asset for certain lignite costs that would otherwise be billed through Cleco Power’s FAC and any reasonable incremental third-party professional costs related to the closure of the mine. In 2020, Cleco Power revised depreciation rates for the Dolet Hills Power Station to utilize the December 31, 2021, expected end-of-life and early retirement of the Dolet Hills Power Station and defer depreciation expense to a regulatory asset for the amount in excess of the previously approved depreciation rates by the LPSC. The Dolet Hills Power Station was retired on December 31, 2021. In 2022, Cleco Power filed an application with the LPSC requesting approval of the regulatory treatment and recovery of stranded and decommissioning costs associated with the retirement of the Dolet Hills Power Station over 20 years as well as recovery of deferred fuel and mine-related costs. On April 19, 2024, the LPSC approved an uncontested settlement that contains a provision for a $40.0 million reduction in the regulatory asset associated with the Dolet Hills Power Station. This amount was recorded as a reduction to the associated regulatory asset on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets and an increase to Depreciation and amortization on Cleco’s and Cleco Power’s Statements of Income. At June 30, 2024, $12.3 million of the ARO regulatory asset, which is related to the Dolet Hills Power Station, was reclassified to the Dolet Hills Power Station Closure Costs regulatory asset. This amount was included in the related securitization application filed with the LPSC on May 17, 2024. Management anticipates the securitization of these costs to close by the end of March 2025, and as a result, reclassified these costs as current Regulatory assets on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. For more information about the settlement, see Note 14 — “ Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees — Litigation — LPSC Audits and Reviews — Dolet Hills Prudency Review.” Solar Development Costs In July 2022, Cleco Power entered into a long-term agreement to purchase, among other things, the output, capacity, and current and future environmental resource credits of a 240-MW solar electric generation facility to be constructed in DeSoto Parish, Louisiana and owned by a third party. On September 17, 2024, the LPSC approved the agreement and authorized Cleco Power to establish a regulatory asset for the stipulated settlement of development costs incurred through December 31, 2023, associated with the long-term agreement. As approved by the LPSC, Cleco Power will begin amortizing these costs over 25 years once it begins purchasing power from the third party, which is expected by January 2027. Residential Revenue Decoupling Under the terms of Cleco Power’s new FRP, effective July 1, 2024, Cleco Power implemented a residential revenue decoupling mechanism through its infrastructure and incremental cost recovery rider that provides a charge or credit to its residential customers for any under or over collection of residential base revenue as a result of changes in usage driven by weather or other measures. The under or over collection of residential base revenue is assessed on Cleco Power’s rate year and an associated credit or charge for decoupling, not to exceed $3.0 million, will be adjusted for the infrastructure and incremental cost recovery rider filings for July 2025 and 2026, respectively. Storm Reserves Cleco Power has a storm reserve to fund future storm restoration costs. Accumulated storm restoration costs that are probable of recovery from retail customers are netted against the storm reserve. At December 31, 2023, Cleco Power had a storm reserve balance of $111.5 million, net of $2.5 million of accumulated restoration costs. During 2024, Cleco Power’s service territory was impacted by multiple severe weather events resulting in significant storm restoration costs. At September 30, 2024, Cleco Power had a storm reserve balance of $81.2 million, net of $37.3 million of accumulated storm restoration costs. For more information on the storm restoration costs associated with severe weather events that impacted Cleco Power’s service territory, see Note 18 — “Storm Restoration.”
Pension Plan and Employee Benefits	Employees hired before August 1, 2007, are covered by a non-contributory, defined benefit pension plan. Based on the funding assumptions at December 31, 2023, management estimates that pension contributions totaling $94.2 million will be required through 2028, of which $25.7 million is required in 2024. In April 2024 and July 2024, Cleco made payments of $3.5 million and $7.1 million, respectively, toward its 2024 contribution requirement. In July 2024, Cleco also made a $15.2 million required contribution payment towards the 2023 plan year. In June 2024, an amendment to the pension plan was executed allowing the transfer of the cash balance and pension liabilities to the Cleco Cajun Purchaser’s pension plan. This transfer was for the former Cleco Cajun employees that became employees of the Cleco Cajun Purchasers following the closing of the Cleco Cajun Divestiture. The transfer was completed in June 2024. Cleco’s retirees may be eligible to receive Other Benefits. Dependents of Cleco’s retirees may also be eligible to receive Other Benefits with the exception of life insurance benefits. Certain current and former Cleco officers are covered by SERP. Cleco does not fund the SERP liability but instead pays for current benefits out of cash available of the respective company of the officer. Because SERP is a non-qualified plan, Cleco has purchased life insurance policies on certain SERP participants as a mechanism to provide a source of funding. These policies are held in a rabbi trust formed by Cleco Power. The rabbi trust is the named beneficiary of the life insurance policies and, therefore, receives the proceeds upon the death of the insured participants. The life insurance policies may be used to reimburse Cleco for benefits paid from general funds, pay the SERP participants’ death benefits, or pay future SERP payments. Market conditions could have a significant impact on the cash surrender value of these life insurance policies. Because SERP is a non-qualified plan, the assets of the trust could be used to satisfy general creditors of Cleco Power in the event of insolvency. Cleco Power is the plan sponsor and Support Group is the plan administrator.
Income Taxes	Cleco classifies all interest related to uncertain tax positions as a component of interest payable and interest expense.Cleco classifies income tax penalties as a component of other expense.
Variable Interest Entities	Cleco and Cleco Power apply the equity method of accounting to report the investment in Oxbow in the consolidated financial statements. Under the equity method, the assets and liabilities of this entity are reported as Equity investment in investee on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. The revenue and expenses (excluding income taxes) of this entity are netted and reported as equity income or loss from investees on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income.
Equity Method Investments	Cleco and Cleco Power apply the equity method of accounting to report the investment in Oxbow in the consolidated financial statements. Under the equity method, the assets and liabilities of this entity are reported as Equity investment in investee on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. The revenue and expenses (excluding income taxes) of this entity are netted and reported as equity income or loss from investees on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income.
