FORWARD-LOOKING STATEMENTS

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This document includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are based on management’s beliefs and assumptions and can often be identified by terms and phrases that include “anticipate,” “believe,” “intend,” “estimate,” “expect,” “continue,” “should,” “could,” “may,” “plan,” “project,” “predict,” “will,” “potential,” “forecast,” “target,” “guidance,” “outlook” or other similar terminology. Various factors may cause actual results to be materially different than the suggested outcomes within forward-looking statements; accordingly, there is no assurance that such results will be realized. These factors include, but are not limited to:

◦The ability to implement our business strategy, including our carbon emission reduction goals;

◦State, federal and foreign legislative and regulatory initiatives, including costs of compliance with existing and future environmental requirements, including those related to climate change, as well as rulings that affect cost and investment recovery or have an impact on rate structures or market prices;

◦The extent and timing of costs and liabilities to comply with federal and state laws, regulations and legal requirements related to coal ash remediation, including amounts for required closure of certain ash impoundments, are uncertain and difficult to estimate;

◦The ability to recover eligible costs, including amounts associated with coal ash impoundment retirement obligations, asset retirement and construction costs related to carbon emissions reductions, and costs related to significant weather events, and to earn an adequate return on investment through rate case proceedings and the regulatory process;

◦The costs of decommissioning nuclear facilities could prove to be more extensive than amounts estimated and all costs may not be fully recoverable through the regulatory process;

◦The impact of extraordinary external events, such as the pandemic health event resulting from COVID-19, and their collateral consequences, including the disruption of global supply chains or the economic activity in our service territories;

◦Costs and effects of legal and administrative proceedings, settlements, investigations and claims;

◦Industrial, commercial and residential growth or decline in service territories or customer bases resulting from sustained downturns of the economy, reduced customer usage due to cost pressures from inflation or fuel costs, and the economic health of our service territories or variations in customer usage patterns, including energy efficiency efforts, natural gas building and appliance electrification, and use of alternative energy sources, such as self-generation and distributed generation technologies;

◦Federal and state regulations, laws and other efforts designed to promote and expand the use of energy efficiency measures, natural gas electrification, and distributed generation technologies, such as private solar and battery storage, in Duke Energy service territories could result in a reduced number of customers, excess generation resources as well as stranded costs;

◦Advancements in technology;

◦Additional competition in electric and natural gas markets and continued industry consolidation;

◦The influence of weather and other natural phenomena on operations, including the economic, operational and other effects of severe storms, hurricanes, droughts, earthquakes and tornadoes, including extreme weather associated with climate change;

◦Changing investor, customer and other stakeholder expectations and demands including heightened emphasis on environmental, social and governance concerns and costs related thereto;

◦The ability to successfully operate electric generating facilities and deliver electricity to customers including direct or indirect effects to the ~~company~~Company resulting from an incident that affects the United States electric grid or generating resources;

◦Operational interruptions to our natural gas distribution and transmission activities;

◦The availability of adequate interstate pipeline transportation capacity and natural gas supply;

◦The impact on facilities and business from a terrorist or other attack, war, vandalism, cybersecurity threats, data security breaches, operational events, information technology failures or other catastrophic events, such as fires, explosions, pandemic health events or other similar occurrences;

◦The inherent risks associated with the operation of nuclear facilities, including environmental, health, safety, regulatory and financial risks, including the financial stability of third-party service providers;

◦The timing and extent of changes in commodity prices and interest rates and the ability to recover such costs through the regulatory process, where appropriate, and their impact on liquidity positions and the value of underlying assets;

◦The results of financing efforts, including the ability to obtain financing on favorable terms, which can be affected by various factors, including credit ratings, interest rate fluctuations, compliance with debt covenants and conditions, an individual utility’s generation mix, and general market and economic conditions;

◦Credit ratings of the Duke Energy Registrants may be different from what is expected;

◦Declines in the market prices of equity and fixed-income securities and resultant cash funding requirements for defined benefit pension plans, other post-retirement benefit plans and nuclear decommissioning trust funds;


FORWARD-LOOKING STATEMENTS

◦Construction and development risks associated with the completion of the Duke Energy Registrants’ capital investment projects, including risks related to financing, timing and receipt of necessary regulatory approvals, obtaining and complying with terms of permits, meeting construction budgets and schedules and satisfying operating and environmental performance standards, as well as the ability to recover costs from customers in a timely manner, or at all;

◦Changes in rules for regional transmission organizations, including changes in rate designs and new and evolving capacity markets, and risks related to obligations created by the default of other participants;

◦The ability to control operation and maintenance costs;

◦The level of creditworthiness of counterparties to transactions;

◦The ability to obtain adequate insurance at acceptable costs;

◦Employee workforce factors, including the potential inability to attract and retain key personnel;

◦The ability of subsidiaries to pay dividends or distributions to Duke Energy Corporation holding company (the Parent);

◦The performance of projects undertaken by our ~~nonregulated~~ businesses and the success of efforts to invest in and develop new ~~opportunities, as well as the successful sale of the Commercial Renewables Disposal Groups;~~opportunities;

◦The effect of accounting and reporting pronouncements issued periodically by accounting standard-setting bodies and the SEC;

◦The impact of United States tax legislation to our financial condition, results of operations or cash flows and our credit ratings;

◦The impacts from potential impairments of goodwill or equity method investment carrying values;

◦Asset or business acquisitions and dispositions may not yield the anticipated benefits; and

◦The actions of activist shareholders could disrupt our operations, impact our ability to execute on our business strategy, or cause fluctuations in the trading price of our common stock.

Additional risks and uncertainties are identified and discussed in the Duke Energy Registrants' reports filed with the SEC and available at the SEC's website at sec.gov. In light of these risks, uncertainties and assumptions, the events described in the forward-looking statements might not occur or might occur to a different extent or at a different time than described. Forward-looking statements speak only as of the date they are made and the Duke Energy Registrants expressly disclaim ~~any~~an obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

FINANCIAL STATEMENTS			ORGANIZATION AND BASIS OF PRESENTATION

Index to Combined Notes to Condensed Consolidated Financial Statements

The unaudited notes to the Condensed Consolidated Financial Statements that follow are a combined presentation. The following list indicates the registrants to which the footnotes apply.

Applicable Notes

Registrant

•

Duke Energy Carolinas

•

Progress Energy

•

Duke Energy Progress

•

Duke Energy Florida

•

Duke Energy Ohio

•

Duke Energy Indiana

•

Piedmont

•

Tables within the notes may not sum across due to (i) Progress Energy's consolidation of Duke Energy Progress, Duke Energy Florida and other subsidiaries that are not registrants and (ii) subsidiaries that are not registrants but included in the consolidated Duke Energy balances.

1. ORGANIZATION AND BASIS OF PRESENTATION

BASIS OF PRESENTATION

These Condensed Consolidated Financial Statements 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 information and notes required by GAAP for annual financial statements and should be read in conjunction with the Consolidated Financial Statements in the Duke Energy's Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023.

The information in these combined notes relates to each of the Duke Energy Registrants as noted in the Index to Combined Notes to Condensed Consolidated Financial Statements. However, none of the registrants make any representations as to information related solely to Duke Energy or the subsidiaries of Duke Energy other than itself.

These Condensed Consolidated Financial Statements, in the opinion of the respective companies’ management, reflect all normal recurring adjustments necessary to fairly present the financial position and results of operations of each of the Duke Energy Registrants. Amounts reported in Duke Energy’s interim Condensed Consolidated Statements of Operations and each of the Subsidiary Registrants’ interim Condensed Consolidated Statements of Operations and Comprehensive Income are not necessarily indicative of amounts expected for the respective annual periods due to effects of seasonal temperature variations on energy consumption, regulatory rulings, timing of maintenance on electric generating units, changes in mark-to-market valuations, changing commodity prices 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.

BASIS OF CONSOLIDATION

These Condensed Consolidated Financial Statements include, after eliminating intercompany transactions and balances, the accounts of the Duke Energy Registrants and subsidiaries or VIEs where the respective Duke Energy Registrants have control. See Note 12 for additional information on VIEs. These Condensed Consolidated Financial Statements also reflect the Duke Energy Registrants’ proportionate share of certain jointly owned generation and transmission facilities.

Discontinued Operations

Duke Energy has elected to present cash flows of discontinued operations combined with cash flows of continuing operations. Unless otherwise noted, the notes to these condensed consolidated financial statements exclude amounts related to discontinued operations for all periods presented. For the three months ended March 31, ~~2023,~~2024, and ~~2022,~~2023, the Loss From Discontinued Operations, net of tax on Duke Energy's Condensed Consolidated Statements of Operations includes amounts related to noncontrolling interests. A portion of Noncontrolling interests on Duke Energy's Condensed Consolidated Balance Sheets relates to discontinued operations for the periods presented. See Note 2 for discussion of discontinued operations related to the Commercial Renewables Disposal Groups.

NONCONTROLLING INTEREST

Duke Energy maintains a controlling financial interest in certain less than wholly owned ~~nonregulated~~ subsidiaries. As a result, Duke Energy consolidates these subsidiaries and presents the third-party investors' portion of Duke Energy's net income (loss), net assets and comprehensive income (loss) as noncontrolling interest. Noncontrolling interest is included as a component of equity on the Condensed Consolidated Balance Sheets. Operating agreements of Duke Energy's subsidiaries with noncontrolling interest allocate profit and loss based on their pro rata shares of the ownership interest in the respective subsidiary. Therefore, Duke Energy allocates net income or loss and other comprehensive income or loss of these subsidiaries to the owners based on their pro rata shares.


FINANCIAL STATEMENTS			ORGANIZATION AND BASIS OF PRESENTATION

CASH, CASH EQUIVALENTS AND RESTRICTED CASH

Duke Energy, Duke Energy Carolinas, Progress Energy, Duke Energy Progress and Duke Energy Florida have restricted cash balances related primarily to collateral assets, escrow deposits and VIEs. See Notes 10 and 12 for additional information. Restricted cash amounts are included in Other within Current Assets and Other Noncurrent Assets on the Condensed Consolidated Balance Sheets. The following table presents the components of cash, cash equivalents and restricted cash included in the Condensed Consolidated Balance Sheets.

ACCOUNTS PAYABLE

Duke Energy ~~maintains~~has a voluntary supply chain finance program (the “program”) ~~with a global financial institution. The program is voluntary and~~that allows Duke Energy suppliers, at their sole discretion, to sell their receivables from Duke Energy to ~~the~~a global financial institution at a rate that leverages Duke Energy’s credit rating and which may result in favorable terms compared to the rate available to the supplier on their own credit rating. Suppliers participating in the program determine at their sole discretion, which invoices they will sell to the financial institution. Suppliers’ decisions on which invoices are sold do not impact Duke ~~Energy confirms invoices sold by suppliers under the program to the financial institution and pays the financial institution~~Energy’s payment terms, which are based on commercial terms negotiated between Duke Energy and the supplier regardless of program participation. ~~Suppliers’ decisions on which invoices are sold do not impact Duke Energy’s payment terms.~~ The commercial terms negotiated between Duke Energy and its suppliers are consistent regardless of whether the supplier elects to participate in the program. Duke Energy does not issue any guarantees with respect to the program and does not participate in negotiations between suppliers and the financial institution. Duke Energy does not have an economic interest in the supplier’s decision to participate in the program and receives no interest, fees or other benefit from the financial institution based on supplier participation in the program.

2. DISPOSITIONS

Sale of Commercial Renewables Segment

In ~~August 2022,~~2023, Duke Energy ~~announced a strategic review~~completed the sale of ~~its commercial renewables business. Since 2007, Duke Energy has built a portfolio of commercial wind, solar and battery projects across~~substantially all the U.S., and established a development pipeline. Duke Energy has developed a strategy to focus on renewables, grid and other investment opportunities within its regulated operations. In November 2022, Duke Energy committed to a plan to sellassets in the Commercial Renewables business ~~segment, excluding~~segment. The disposal process for the ~~offshore wind contract for Carolina Long Bay, which was moved~~remaining assets is expected to the EU&I segment. Prior to March 2023, Duke Energy was actively marketing the Commercial Renewables business as two separate disposal groups, the utility-scale solar and wind group and the distributed generation group. In March 2023, assets for certain projects were removedbe completed around midyear 2024, with net proceeds from the utility-scale solar and wind group and placed in a separate disposal group (collectively, Commercial Renewables Disposal Groups) and a pretax impairment of approximately $220 million was recorded for the three months ended March 31, 2023. The sales processes for the Commercial Renewables Disposal Groups are ongoing and Duke Energy expectsdispositions not anticipated to ~~dispose of these groups in the second half of 2023.~~be material.

Assets Held For Sale and Discontinued Operations

The Commercial Renewables Disposal Groups were classified as held for sale and as discontinued operations in the fourth quarter of 2022. ~~Originally~~No interest from corporate level debt was allocated to discontinued operations and the related restricted cash and interest rate swaps were not expected to transfer to a buyer but during the marketing process it was determined they would be included with the sale and were classified as held for sale in March 2023. As a result, adjustments were made to the December 31, 2022, Consolidated Balance Sheet to present debt and the related restricted cash and interest rate swaps as held for sale. Nono adjustments were made to the historical activity within the Consolidated Statements of Comprehensive Income, Consolidated Statements of Cash Flows or the Consolidated Statements of Changes in Equity. Unless otherwise noted, the notes to these consolidated financial statements exclude amounts related to discontinued operations for all periods presented.

~~No interest from corporate level debt was allocated to discontinued operations.~~

FINANCIAL STATEMENTS			DISPOSITIONS

The Commercial Renewables Disposal Groups' held for sale assets included pretax impairments of approximately $1.7 billion at December 31, 2022. In the first quarter of 2023, a pretax impairment of approximately $220 million was recorded to write-down the carrying amount of property, plant and equipment assets to the estimated fair value of the business, based on the expected selling price less estimated costs to sell. The first quarter impairment was included in Loss from Discontinued Operations, net of tax, in Duke Energy's Condensed Consolidated Statements of Operations and Comprehensive Income for the three months ended March 31, 2023. The fair value was primarily determined from market information obtained through the bidding process and discounted cash flow analysis. The discounted cash flow model utilized Level 2 and Level 3 inputs. The fair value hierarchy levels are further discussed in Note 11. The impairment will be updated, if necessary, based on market changes or the final sales price, including all closing adjustments.

Duke Energy has elected not to separately disclose discontinued operations on Duke Energy's Consolidated Statements of Cash Flows. The following table summarizes Duke Energy's cash flows from discontinued operations related to the Commercial Renewables Disposal Groups.

Other Sale-Related Matters

Duke Energy (Parent) and several Duke Energy renewables project companies, located in the ERCOT market, were named in several lawsuits arising out of Texas Storm Uri, which occurred in February 2021. The legal actions related to ~~Duke Energy (Parent) from these lawsuits will remain~~all but one of the project companies in this matter transferred to affiliates of Brookfield in conjunction with ~~Duke Energy (Parent) and any future activity related to Duke Energy (Parent) as a defendant~~the transaction closing in ~~these lawsuits will be presented in discontinued operations.~~October 2023. See Note 45 for more information.

As part of the purchase and sale agreement for the distributed generation group, Duke Energy has agreed to retain certain guarantees, with expiration dates between 2029 through 2034, related to tax equity partners' assets and operations that will be disposed of via sale. Duke Energy has obtained certain guarantees from the buyers in regards to future performance obligations to assist in limiting Duke Energy's exposure under the retained guarantees. The fair value of the guarantees is immaterial as Duke Energy does not believe conditions are likely for performance under these guarantees.

4. REGULATORY MATTERS

RATE-RELATED INFORMATION

The NCUC, PSCSC, FPSC, IURC, PUCO, TPUC and KPSC approve rates for retail electric and natural gas services within their states. The FERC approves rates for electric sales to wholesale customers served under cost-based rates (excluding Ohio and Indiana), as well as sales of transmission service. The FERC also regulates certification and siting of new interstate natural gas pipeline projects. For open regulatory matters, unless otherwise noted, the Subsidiary Registrants and Duke Energy Kentucky cannot predict the outcome or ultimate resolution of their respective matters.

Duke Energy Carolinas and Duke Energy Progress

Nuclear Station Subsequent License Renewal

On June 7, 2021, Duke Energy Carolinas filed a subsequent license renewal (SLR) application for the Oconee Nuclear Station (ONS) with the U.S. Nuclear Regulatory Commission (NRC) to renew ONS’s operating license for an additional 20 years. The SLR would extend operations of the facility from 60 to 80 years. The current licenses for units 1 and 2 expire in 2033 and the license for unit 3 expires in 2034. By a Federal Register Notice dated July 28, 2021, the NRC provided a 60-day comment period for persons whose interest may be affected by the issuance of a subsequent renewed license for ONS to file a request for a hearing and a petition for leave to intervene. On September 27, 2021, Beyond Nuclear and Sierra Club (Petitioners) filed a Hearing Request and Petition to Intervene (Hearing Request) and a Petition for Waiver. The Hearing Request proposed three contentions and claimed that Duke Energy Carolinas did not satisfy the National Environmental Policy Act (NEPA) of 1969, as amended, or the NRC’s NEPA-implementing regulations. Following Duke Energy Carolinas' answer and the Petitioners' reply, on February 11, 2022, the Atomic Safety and Licensing Board (ASLB) issued its decision on the Hearing Request and found that the Petitioners failed to establish that the proposed contentions are litigable. The ASLB also denied the Petitioners' Petition for Waiver and terminated the proceeding.


FINANCIAL STATEMENTS			REGULATORY MATTERS

On February 24, 2022, the NRC issued a decision in the SLR appeal related to Florida Power and Light's Turkey Point nuclear generating station in Florida. The NRC ruled that the NRC’s license renewal Generic Environmental Impact Statement (GEIS) does not apply to SLR because the GEIS does not address SLR. The decision overturned a 2020 NRC decision that found the GEIS applies to SLR. Although Turkey Point is not owned or operated by a Duke Energy Registrant, the NRC’s order applies to all SLR applicants, including ONS. The NRC order also indicated no subsequent renewed licenses will be issued until the NRC staff has completed an adequate NEPA review for each application. On April 5, 2022, the NRC approved a 24-month rulemaking plan that will enable the NRC staff to complete an adequate NEPA review. Although an SLR applicant may wait until the rulemaking is completed, the NRC also noted that an applicant may submit a supplement to its environmental report providing information on environmental impacts during the SLR period prior to the rulemaking being completed. On November 7, 2022, Duke Energy Carolinas submitted a supplement to its environmental report addressing environmental impacts during the SLR period. On September 14, 2023, the NRC posted on its website that the issuance of the GEIS will now be issued in August 2024 instead of May 2024 due to the volume and technical complexity of the comments received. On March 6, 2024, the NRC staff submitted the rulemaking, which included the updated GEIS, to the NRC.

On December 19, 2022, the NRC published a notice in the Federal Register that the NRC will conduct a limited scoping process to gather additional information necessary to prepare an environmental impact statement (EIS) to evaluate the environmental impacts at ONS during the SLR period. The NRC received comments from the EPA and the Petitioners and these comments identify 18 potential impacts that should be considered by the NRC in the EIS, which include, but are not limited to, climate change and flooding, environmental justice, severe accidents, and external events. ~~Currently,~~On February 8, 2024, the NRC ~~expects~~issued the Oconee site-specific draft EIS. The NRC and EPA published the notice for the public to ~~publish~~submit comments on the ONS site-specific draft EIS. On April 29, 2024, the petitioners filed a hearing request. The request proposed three contentions and claimed that the ONS site-specific draft EIS ~~in October 2023.~~is inadequate to satisfy the requirements of NEPA and the NRC’s NEPA-implementing regulations. Duke Energy Carolinas' deadline to respond to any such requests was extended to May 31, 2024.

On December 19, 2022, the NRC issued the Safety Evaluation Report (SER) for the safety portion of the SLR application. The NRC determined Duke Energy Carolinas met the requirements of the applicable regulations and identified actions that have been taken or will be taken to manage the effects of aging and address time-limited analyses. Duke Energy Carolinas and the NRC met with the Advisory Committee on Reactor Safeguards ~~(ACR~~S)(ACRS) on February 2, 2023, to discuss issues regarding the SER and SLR application. On February 25, 2023, the ACRS issued a report to the NRC on the safety aspects of the ONS SLR application, which concluded that the established programs and commitments made by Duke Energy Carolinas to manage age-related degradation provide confidence that ONS can be operated in accordance with its current licensing basis for the subsequent period of extended operation without undue risk to the health and safety of the public and the SLR application for ONS should be approved.

Although the NRC’s GEIS applicability decision ~~will delay~~has delayed completion of the SLR proceeding, Duke Energy Carolinas does not believe it changes the probability that the ONS subsequent renewed licenses will ultimately be issued, although Duke Energy Carolinas cannot guarantee the outcome of the license application process.

Duke Energy Carolinas and Duke Energy Progress intend to seek renewal of operating licenses and 20-year license extensions for all of their nuclear stations. ~~New~~Accordingly, new depreciation rates were implemented for all of the nuclear facilities during the second quarter of 2021. ~~Duke Energy Carolinas and Duke Energy Progress cannot predict the outcome of these additional relicensing proceedings.~~

~~Storm Cost Securitization~~

On June 15, 2022, the South Carolina General Assembly unanimously adopted S. 1077 (Act 227) in both the House and Senate and the bill was signed into law on June 17, 2022. The legislation enables the PSCSC to permit the issuance of bonds for the payment of storm costs and the creation of a storm charge for repayment.

On August 5, 2022, Duke Energy Progress filed a petition with the PSCSC for review and approval of deferred storm costs to be securitized of approximately $223 million. On February 7, 2023, a stipulation was reached with all parties in the proceeding regarding certain items identified through the Office of Regulatory Staff (ORS) audit of storm costs. The evidentiary hearing was held on March 1, 2023. On April 20, 2023, the PSCSC issued its order, approving the stipulation and determining unresolved issues in the case, resulting in approximately $171 million in projected deferred storm costs eligible to be securitized. The difference in the original filed amount and the approved amount is primarily related to the stipulation with the ORS in which Duke Energy Progress agreed to apply a debt-only rate of return for the calculation of carrying costs during the deferral period for the deferred storm costs.

Duke Energy Carolinas

2023 North Carolina Rate Case

On January 19, 2023, Duke Energy Carolinas filed a PBR application with the NCUC to request an increase in base rate retail revenues.

2024 South Carolina Rate Case

On January 4, 2024, Duke Energy Carolinas filed a rate case with the PSCSC to request a net increase in annual retail revenues of 11.4%, or approximately $239 million, in the first two years, and an additional overall increase of about 4.1%, or approximately $84 million additional revenue, after the first two years. The requested increases, if approved, would result in an overall average 15.5% increase in annual retail revenues, or approximately $323 million, prior to mitigation efforts. Duke Energy Carolinas requested an ROE of 10.5% with an equity ratio of 53%. To mitigate the rate increase, Duke Energy Carolinas has proposed to accelerate the return of remaining federal unprotected EDIT balances to customers over two years. This offset reduces the impact to customers in the first two years to the effective net increase of 11.4% after which the credit for EDIT balances expire.

On January 14, 2021, Duke Energy Florida filed a Settlement Agreement (the “2021 Settlement”) with the FPSC. The parties to the 2021 Settlement include Duke Energy Florida, the Office of Public Counsel (OPC), the Florida Industrial Power Users Group, White Springs Agricultural Chemicals, Inc. d/b/a PCS Phosphate and NUCOR Steel Florida, Inc. (collectively, the “Parties”).

Pursuant to the 2021 Settlement, the Parties agreed to a base rate stay-out provision that expires year-end 2024; however, Duke Energy Florida is allowed an increase to its base rates of an incremental $67 million in 2022, $49 million in 2023 and $79 million in 2024, subject to adjustment in the event of tax reform during the years 2021, 2022 and 2023. The Parties also agreed to an ROE band of 8.85% to 10.85% with a midpoint of 9.85% based ~~on a capital structure~~upon an equity ratio of 53% ~~equity and 47% debt.~~. The ROE band can be increased by 25 basis points if the average 30-year U.S. Treasury rate increases 50 basis points or more over a six-month period in which case the midpoint ROE would rise from 9.85% to 10.10%. On July 25, 2022, this provision was triggered. Duke Energy Florida filed a petition with the FPSC on August 12, 2022, to increase the ROE effective August 2022 with a base rate increase effective January 1, 2023. The FPSC approved this request on October 4, 2022. The 2021 Settlement Agreement also provided that Duke Energy Florida will be able to retain $173 million of the expected Department of Energy (DOE) award from its lawsuit to recover spent nuclear fuel to mitigate customer rates over the term of the 2021 Settlement. In return, Duke Energy Florida is permitted to recognize the $173 million into earnings through the approved settlement period. Duke Energy Florida settled the DOE lawsuit and received payment of approximately $180 million on June 15, 2022, of which the retail portion was approximately $154 million. The 2021 Settlement authorizes Duke Energy Florida to collect the difference between $173 million and the $154 million retail portion of the amount received through the capacity cost recovery clause. As of March 31, ~~2023,~~2024, Duke Energy Florida has recognized $149 million into earnings, including $8 million and $54 million ~~into earnings.~~recognized during the three months ended March 31, 2024, and 2023, respectively. The remaining ~~$119~~$24 million is expected to be recognized ~~over the remainder of 2023 and 2024, while also remaining within the approved return on equity band.~~in 2024.

The 2021 Settlement also contained a provision to recover or flow back the effects of tax law changes. As a result of the IRA enacted on August 16, 2022, Duke Energy Florida is eligible for PTCs associated with solar facilities placed in service beginning in January 2022. Duke Energy Florida filed a petition with the FPSC on October 17, 2022, to reduce base rates effective January 1, 2023, by $56 million to flow back the expected 2023 PTCs and to flow back the expected 2022 PTCs via an adjustment to the capacity cost recovery clause. On December 14, 2022, the FPSC issued an order approving Duke Energy Florida's petition.

In addition to these terms, the 2021 Settlement contained provisions related to the accelerated depreciation of Crystal River Units 4-5, the approval of approximately $1 billion in future investments in new cost-effective solar power, the implementation of a new Electric Vehicle Charging Station Program and the deferral and recovery of costs in connection with the implementation of Duke Energy Florida’s Vision Florida program, which explores various emerging non-carbon emitting generation technology, distributed technologies and resiliency projects, among other things. The 2021 Settlement also resolved remaining unrecovered storm costs for Hurricane Michael and Hurricane Dorian.

The FPSC approved the 2021 Settlement on May 4, 2021, issuing an order on June 4, 2021. Revised customer rates became effective January 1, 2022, with subsequent base rate increases effective January 1, 2023, and January 1, 2024.

New rates went into effect October 13, 2023. The Company's request to align the depreciation rates of East Bend with a 2035 retirement date was denied and the KPSC ordered depreciation rates with a 2041 retirement date for the unit. The KPSC did approve the request to align the depreciation rates of Woodsdale CT with a 2040 retirement date and denied the voluntary community-based renewable subscription program and the two electric vehicle charging programs.

Duke Energy Indiana

~~2019 Indiana Rate Case~~

On July 2, 2019, Duke Energy Indiana filed a general rate case with the IURC for a rate increase for retail customers of approximately $395 million. The rebuttal case, filed on December 4, 2019, updated the requested revenue requirement to result in a 15.6% or $396 million average retail rate increase, including the impacts of the utility receipts tax. On June 29, 2020, the IURC issued an order in the rate case approving a revenue increase of $146 million before certain adjustments and ratemaking refinements. The order approved Duke Energy Indiana’s requested forecasted rate base of $10.2 billion as of December 31, 2020, including the Edwardsport Integrated Gasification Combined Cycle (IGCC) Plant. The IURC reduced Duke Energy Indiana’s request by slightly more than $200 million, when accounting for the utility receipts tax and other adjustments. Approximately 50% of the reduction was due to a prospective change in depreciation and use of regulatory asset for the end-of-life inventory at retired generating plants, approximately 20% was due to the approved ROE of 9.7% versus the requested ROE of 10.4% and approximately 20% was related to miscellaneous earnings neutral adjustments. Step one rates were estimated to be approximately 75% of the total and became effective on July 30, 2020. Step two rates estimated to be the remaining 25% of the total rate increase were approved on July 28, 2021, and implemented in August 2021.

Several groups appealed the IURC order to the Indiana Court of Appeals. The Indiana Court of Appeals affirmed the IURC decision on May 13, 2021. However, upon appeal by the Indiana Office of Utility Consumer Counselor (OUCC) and the Duke Industrial Group on March 10, 2022, the Indiana Supreme Court found that the IURC erred in allowing Duke Energy Indiana to recover coal ash costs incurred before the IURC’s rate case order in June 2020. The Indiana Supreme Court found that allowing Duke Energy Indiana to recover coal ash costs incurred between rate cases that exceeded the amount built into base rates violated the prohibition against retroactive ratemaking. The IURC’s order has been remanded to the IURC for additional proceedings consistent with the Indiana Supreme Court’s opinion. As a result of the court's opinion, Duke Energy Indiana recognized pretax charges of approximately $211 million to Impairment of assets and other charges and $46 million to Operating revenues in the Condensed Consolidated Statements of Operations for the three months ended March 31, ~~2022~~. D~~uke Energy Indiana filed a request for rehearing with the Supreme Court on April 11, 2022, which the court denied on~~ ~~May 26, 2022. Duke Energy Indiana filed its testimony in the remand proceeding on August 18, 2022~~. On February 3, 2023, Duke Energy Indiana filed a settlement agreement reached with the OUCC and Duke Industrial Group, which includes an agreed amount of approximately $70 million of refunds to be paid to customers. The IURC approved this settlement agreement in its entirety on April 12, 2023.

~~2020~~ Indiana Coal Ash Recovery ~~Case~~

In Duke Energy Indiana’s 2019 rate case, the IURC ~~also~~ opened a subdocket for post-2018 coal ash related expenditures. Duke Energy Indiana filed testimony on April 15, 2020, in the coal ash subdocket requesting recovery for the post-2018 coal ash basin closure costs for plans that have been approved by the Indiana Department of Environmental Management (IDEM) as well as continuing deferral, with carrying costs, on the balance. ~~An evidentiary hearing was held on September 14, 2020. Briefing was completed by mid-September 2021.~~ On November 3, 2021, the IURC issued an order allowing recovery for post-2018 coal ash basin closure costs for the plans that have been approved by IDEM, as well as continuing deferral, with carrying costs, on the balance. The OUCC and the Duke Industrial Group appealed. The Indiana Court of Appeals issued its opinion on February 21, 2023, reversing the IURC's order to the extent that it allowed Duke Energy Indiana to recover federally mandated costs incurred prior to the IURC's November 3, 2021 order. In addition, the court found that any costs incurred pre-petition to determine federally mandated compliance options were not specifically authorized by the statute and should also be disallowed. ~~As a result~~

In the second quarter of ~~the Court's opinion,~~2023, Duke Energy Indiana ~~recognized a pretax charge of approximately $175 million~~filed its proposal to ~~Impairment of assets and other charges for the year ended December 31, 2022.

TDSIC 2.0

On November 23, 2021, Duke Energy Indiana filed for approval of the Transmission, Distribution, Storage Improvement Charge 2.0 investment plan for 2023-2028 (TDSIC 2.0). On June 15, 2022, the IURC approved, without modification, TDSIC 2.0, which includes approximately $2 billion in transmission and distribution investments selected to improve customer reliability, harden and improve resiliency of the grid, enable expansion of renewable and distributed energy projects and encourage economic development. In addition, the IURC set up a subdocket to consider ~~the~~a targeted economic development project, which the IURC approved on March 2, 2022. On July 15, 2022, the OUCC filed a notice of appeal to the Indiana Court of Appeals in Duke Energy Indiana’s TDSIC 2.0 proceeding. An appellant brief was filed on October 28, 2022, and Duke Energy Indiana filed its responsive brief on December 28, 2022. The Indiana Court of Appeals issued its opinion on March 9, 2023, affirming the ~~Commission’s~~IURC’s order in its entirety.

Piedmont requested an ROE of 10.5% with an equity ratio of 53%. The rate increase is driven by significant infrastructure upgrade investments since the last general rate case, offset by lower fixed natural gas costs and remaining federal and state tax reform savings to be received by customers. Approximately 40% of the plant additions being rolled into rate base are categories of plant investment that are covered under the IMR mechanism, which was originally approved ~~Piedmont’s petition~~as part of the 2013 North Carolina Rate Case.

ENVIRONMENTAL

Remediation Activities

In addition to AROs recorded as a result of various environmental regulations, the Duke Energy Registrants are responsible for environmental remediation at various sites. These include certain properties that are part of ongoing operations and sites formerly owned or used by Duke Energy entities. These sites are in various stages of investigation, remediation and monitoring. Managed in conjunction with relevant federal, state and local agencies, remediation activities vary based on site conditions and location, remediation requirements, complexity and sharing of responsibility. If remediation activities involve joint and several liability provisions, strict liability, or cost recovery or contribution actions, the Duke Energy Registrants could potentially be held responsible for environmental impacts caused by other potentially responsible parties and may also benefit from insurance policies or contractual indemnities that cover some or all cleanup costs. Liabilities are recorded when losses become probable and are reasonably estimable. The total costs that may be incurred cannot be estimated because the extent of environmental impact, allocation among potentially responsible parties, remediation alternatives and/or regulatory decisions have not yet been determined at all sites. Additional costs associated with remediation activities are likely to be incurred in the future and could be significant. Costs are typically expensed as Operation, maintenance and other on the Condensed Consolidated Statements of Operations unless regulatory recovery of the costs is deemed probable.

Duke Energy Carolinas

~~Ruben Villano, et al. v. Duke Energy Carolinas, LLC~~

On June 16, 2021, a group of nine individuals went over a low head dam adjacent to the Dan River Steam Station in Eden, North Carolina, while water tubing. Emergency personnel rescued four people and five others were confirmed deceased. On August 11, 2021, Duke Energy Carolinas was served with the complaint filed in Durham County Superior Court on behalf of four survivors, which was later amended to include all the decedents along with the survivors. The lawsuit alleges that Duke Energy Carolinas knew that the river was used for recreational purposes, did not adequately warn about the dam, and created a dangerous and hidden hazard on the Dan River by building and maintaining the low-head dam. Duke Energy Carolinas has reached an agreement in principle that will resolve this matter to the parties' mutual satisfaction. The resolution, which is not expected to have a material financial impact, is subject to court approval by the Durham County Superior Court~~. Duke Energy Carolinas cannot predict the outcome of this matter.~~

NTE Carolinas II, LLC Litigation

In November 2017, Duke Energy Carolinas entered into a standard FERC large generator interconnection agreement (LGIA) with NTE Carolinas II, LLC (NTE), a company that proposed to build a combined-cycle natural gas plant in Rockingham County, North Carolina. On September 6, 2019, Duke Energy Carolinas filed a lawsuit in Mecklenburg County Superior Court against NTE for breach of contract, alleging that NTE's failure to pay benchmark payments for Duke Energy Carolinas' transmission system upgrades required under the interconnection agreement constituted a termination of the interconnection agreement. Duke Energy Carolinas sought a monetary judgment against NTE because NTE failed to make multiple milestone payments. The lawsuit was moved to federal court in North Carolina. NTE filed a motion to dismiss Duke Energy Carolinas’ complaint and brought counterclaims alleging anti-competitive conduct and violations of state and federal statutes. Duke Energy Carolinas filed a motion to dismiss NTE's counterclaims. Both NTE's and Duke Energy Carolinas' motions to dismiss were subsequently denied by the court.

On May 21, 2020, in response to a NTE petition challenging Duke Energy Carolinas' termination of the LGIA, FERC issued a ruling that 1) it has exclusive jurisdiction to determine whether a transmission provider may terminate aan LGIA; 2) FERC approval is required to terminate a conforming LGIA if objected to by the interconnection customer; and 3) Duke Energy may not announce the termination of a conforming LGIA unless FERC has approved the termination. FERC's Office of Enforcement also initiated an investigation of Duke Energy Carolinas into matters pertaining to the LGIA. On April 6, 2023, Duke Energy Carolinas received notice from the FERC Office of Enforcement that they have closed their non-public investigation with no further action recommended.


~~FINANCIAL STATEMENTS~~			~~COMMITMENTS AND CONTINGENCIES~~

Following completion of discovery, Duke Energy Carolinas filed a motion for summary judgment seeking a ruling in its favor as to some of its affirmative claims against NTE and to all of NTE’s counterclaims. On June 24, 2022, the court issued an order partially granting Duke Energy Carolinas' motion by dismissing NTE's counterclaims that Duke Energy Carolinas engaged in anti-competitive behavior in violation of state and federal statutes. On October 12, 2022, the parties executed a settlement agreement with respect to the remaining breach of contract claims in the litigation and a Stipulation of Dismissal was filed with the court on October 13, 2022. On November 11, 2022, NTE filed its Notice of Appeal to the U.S. Court of Appeals for the Fourth Circuit as to the District Court's summary judgment ruling in Duke Energy Carolinas' favor on NTE's antitrust and unfair competition claims. Briefing on NTE's appeal ~~will be~~was completed on June 2,30, 2023. ~~Duke Energy Carolinas cannot predict the outcome of this matter.~~Oral argument is scheduled for May 7, 2024.

Asbestos-related Injuries and Damages Claims

Duke Energy Carolinas has experienced numerous claims for indemnification and medical cost reimbursement related to asbestos exposure. These claims relate to damages for bodily injuries alleged to have arisen from exposure to or use of asbestos in connection with construction and maintenance activities conducted on its electric generation plants prior to 1985.

Duke Energy Carolinas has recognized asbestos-related reserves of ~~$451~~$417 million at March 31, ~~2023,~~2024, and ~~$457~~$423 million at December 31, ~~2022.~~2023. These reserves are classified in Other within Other Noncurrent Liabilities and Other within Current Liabilities on the Condensed Consolidated Balance Sheets. These reserves are based on Duke Energy Carolinas' best estimate for current and future asbestos claims through ~~2042~~2043 and are recorded on an undiscounted basis. In light of the uncertainties inherent in a longer-term forecast, management does not believe they can reasonably estimate the indemnity and medical costs that might be incurred after ~~2042~~2043 related to such potential claims. It is possible Duke Energy Carolinas may incur asbestos liabilities in excess of the recorded reserves.

Duke Energy Carolinas has third-party insurance to cover certain losses related to asbestos-related injuries and damages above an aggregate self-insured retention. Receivables for insurance recoveries were ~~$595~~$572 million at March 31, ~~2023, and at~~2024, and December 31, ~~2022.~~2023. These amounts are classified in Other within Other Noncurrent Assets and Receivables within Current Assets on the Condensed Consolidated Balance Sheets. Any future payments up to the policy limit will be reimbursed by the third-party insurance carrier. Duke Energy Carolinas is not aware of any uncertainties regarding the legal sufficiency of insurance claims. Duke Energy Carolinas believes the insurance recovery asset is probable of recovery as the insurance carrier continues to have a strong financial strength rating.

The reserve for credit losses for insurance receivables is ~~$12~~$9 million as of March 31, 2024, and December 31, 2023, for both Duke Energy and Duke Energy ~~Carolinas as of March 31, 2023, and December 31, 2022.~~Carolinas. The insurance receivable is evaluated based on the risk of default and the historical losses, current conditions and expected conditions around collectability. Management evaluates the risk of default annually based on payment history, credit rating and changes in the risk of default from credit agencies.

Coal Ash Insurance Coverage Litigation

In June 2022, Duke Energy Indiana filed a civil action in Indiana Superior Court against various insurance companies seeking declaratory relief with respect to insurance coverage for coal combustion residuals-related expenses and liabilities covered by third-party liability insurance policies. The insurance policies cover the 1969-1972 and 1984-1985 periods and provide third-party liability insurance for claims and suits alleging property damage, bodily injury and personal injury (or a combination thereof).

The lawsuit remains pending as to the other insurers but is stayed until June 14, 2024, to allow for further settlement negotiations with other defendants.

Other Litigation and Legal Proceedings

The Duke Energy Registrants are involved in other legal, tax and regulatory proceedings arising in the ordinary course of business, some of which involve significant amounts. The Duke Energy Registrants believe the final disposition of these proceedings will not have a material effect on their results of operations, cash flows or financial position. Reserves are classified on the Condensed Consolidated Balance Sheets in Other within Other Noncurrent Liabilities and Other within Current Liabilities.

OTHER COMMITMENTS AND CONTINGENCIES

General

As part of their normal business, the Duke Energy Registrants are party to various financial guarantees, performance guarantees and other contractual commitments to extend guarantees of credit and other assistance to various subsidiaries, investees and other third parties. These guarantees involve elements of performance and credit risk, which are not fully recognized on the Condensed Consolidated Balance Sheets and have uncapped maximum potential payments. However, the Duke Energy Registrants do not believe these guarantees will have a material effect on their results of operations, cash flows or financial position.

In addition, the Duke Energy Registrants enter into various fixed-price, noncancelable commitments to purchase or sell power or natural gas, take-or-pay arrangements, transportation, or throughput agreements and other contracts that may or may not be recognized on their respective Condensed Consolidated Balance Sheets. Some of these arrangements may be recognized at fair value on their respective Condensed Consolidated Balance Sheets if such contracts meet the definition of a derivative and the NPNS exception does not apply. In most cases, the Duke Energy Registrants’ purchase obligation contracts contain provisions for price adjustments, minimum purchase levels and other financial commitments.

6. DEBT AND CREDIT FACILITIES

In April 2024, Duke Energy issued 750 million euros aggregate principal amount of 3.75% senior notes due April 2031. Duke Energy's obligations under its euro-denominated fixed-rate notes were effectively converted to fixed-rate U.S. dollars at issuance through cross-currency swaps, mitigating foreign currency exchange risk associated with the interest and principal payments. The $815 million equivalent in U.S. dollars were used to repay a portion of a $1 billion debt maturity due April 2024, pay down short-term debt and for general corporate purposes. See Note 9 for additional information.

In April 2024, Duke Energy Florida issued $173 million of First Mortgage Bonds due April 2074, with an interest rate of SOFR minus 35 basis points. Proceeds were used to pay down a portion of the DEFR accounts receivable securitization facility maturing in April 2024, and for general company purposes. The terms of the indenture could require repayment in less than 12 months if exercised by the bondholders and, as such, these first mortgage bonds will be classified as Current maturities of long-term debt on the Condensed Consolidated Balance Sheets.

In April 2024, Duke Energy Progress issued $177 million of storm recovery bonds at an interest rate of 5.404%. Proceeds were used to finance the South Carolina portion of restoration expenditures related to the following storms: Pax, Ulysses, Matthew, Florence, Michael, Dorian, Izzy and Jasper.

On or after January 15, 2026, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the convertible notes may convert all or any portion of their convertible notes at their option at any time at the conversion rate then in effect, irrespective of these conditions. Duke Energy will settle conversions of the convertible notes by paying cash up to the aggregate principal amount of the convertible notes to be converted and paying or delivering, as the case may be, cash, shares of Duke Energy's common stock, $0.001 par value per share, or a combination of cash and shares of its common stock, at its election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the convertible notes being converted.

The conversion rate for the convertible notes will initially be 8.4131 shares of Duke Energy's common stock per $1,000 principal amount of convertible notes. The initial conversion price of the convertible notes represents a premium of approximately 25% over the last reported sale price of Duke Energy’s common stock on the NYSE on April 3, 2023. The conversion rate and the corresponding conversion price will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Duke Energy may not redeem the convertible notes prior to the maturity date.

Duke Energy issued the convertible notes pursuant to an indenture, dated as of April 6, 2023, by and between Duke Energy and The Bank of New York Mellon Trust Company, N.A., as trustee. The terms of the convertible notes include customary fundamental change provisions that require repayment of the notes with interest upon certain events, such as a stockholder approved plan of liquidation or if Duke Energy's common stock ceases to be listed on the NYSE.

AVAILABLE CREDIT FACILITIES

Master Credit Facility

In March ~~2023,~~2024, Duke Energy ~~amended~~extended the termination date of its existing $9 billion Master Credit Facility ~~of $9 billion to extend the termination date~~ to March ~~2028.~~2029. The Duke Energy Registrants, excluding Progress Energy, have borrowing capacity under the Master Credit Facility up to a specified sublimit for each borrower. Duke Energy has the unilateral ability at any time to increase or decrease the borrowing sublimits of each borrower, subject to a maximum sublimit for each borrower. The amount available under the Master Credit Facility has been reduced to backstop issuances of commercial paper, certain letters of credit and variable-rate demand tax-exempt bonds that may be put to the Duke Energy Registrants at the option of the holder. An amendment in conjunction with the issuance of the Convertible Senior Notes due April 2026 clarifies that payments due as a result of a conversion of a convertible note would not constitute an event of default.

9. DERIVATIVES AND HEDGING

The Duke Energy Registrants use commodity, interest rate and foreign currency contracts to manage commodity price risk, interest rate risk and foreign currency exchange rate risk. The primary use of commodity derivatives is to hedge the generation portfolio against changes in the prices of electricity and natural gas. Piedmont enters into natural gas supply contracts to provide diversification, reliability and natural gas cost benefits to its customers. Interest rate derivatives are used to manage interest rate risk associated with borrowings. Foreign currency derivatives are used to manage risk related to foreign currency exchange rates on certain issuances of debt. Derivatives related to interest rate risk for the Commercial Renewables Disposal Groups are now classified as held for sale and are excluded from the following disclosures. See Note 2 for further information.

All derivative instruments not identified as NPNS are recorded at fair value as assets or liabilities on the Condensed Consolidated Balance Sheets. Cash collateral related to derivative instruments executed under master netting arrangements is offset against the collateralized derivatives on the Condensed Consolidated Balance Sheets. The cash impacts of settled derivatives are recorded as operating activities or financing activities on the Condensed Consolidated Statements of Cash Flows consistent with the classification of the hedged transaction.

INTEREST RATE RISK

The Duke Energy Registrants are exposed to changes in interest rates as a result of their issuance or anticipated issuance of variable-rate and fixed-rate debt and commercial paper. Interest rate risk is managed by limiting variable-rate exposures to a percentage of total debt and by monitoring changes in interest rates. To manage risk associated with changes in interest rates, the Duke Energy Registrants may enter into interest rate swaps, U.S. Treasury lock agreements and other financial contracts. In anticipation of certain fixed-rate debt issuances, a series of forward-starting interest rate swaps or Treasury locks may be executed to lock in components of current market interest rates. These instruments are later terminated prior to or upon the issuance of the corresponding debt.


~~FINANCIAL STATEMENTS~~			~~DERIVATIVES AND HEDGING~~

Cash Flow Hedges

For a derivative designated as hedging the exposure to variable cash flows of a future transaction, referred to as a cash flow hedge, the effective portion of the derivative's gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings once the future transaction impacts earnings. Amounts for interest rate contracts are reclassified to earnings as interest expense over the term of the related debt. Gains and losses reclassified out of accumulated other comprehensive income (loss) for the three months ended March 31, ~~2023,~~2024, and ~~2022,~~2023, were not material. Duke Energy's interest rate derivatives designated as hedges include forward-starting interest rate swaps not accounted for under regulatory accounting.

Undesignated Contracts

Undesignated contracts primarily include contracts not designated as a hedge because they are accounted for under regulatory accounting or contracts that do not qualify for hedge accounting.

Duke Energy’s interest rate swaps for its regulated operations employ regulatory accounting. With regulatory accounting, the mark-to-market gains or losses on the swaps are deferred as regulatory liabilities or regulatory assets, respectively. Regulatory assets and liabilities are amortized consistent with the treatment of the related costs in the ratemaking process. The accrual of interest on the swaps is recorded as Interest Expense on the Duke Energy Registrant's Condensed Consolidated Statements of Operations and Comprehensive Income.

COMMODITY PRICE RISK

The Duke Energy Registrants are exposed to the impact of changes in the prices of electricity purchased and sold in bulk power markets and natural gas purchases, including Piedmont's natural gas supply contracts. Exposure to commodity price risk is influenced by a number of factors including the term of contracts, the liquidity of markets and delivery locations. To manage risk associated with commodity prices, the Duke Energy Registrants may enter into long-term power purchase or sales contracts and long-term natural gas supply agreements.

Undesignated Contracts

Undesignated contracts primarily include contracts not designated as a hedge because they are accounted for under regulatory accounting or contracts that do not qualify for hedge accounting.

For the Subsidiary Registrants, bulk power electricity and natural gas purchases flow through fuel adjustment clauses, formula-based contracts or other cost-sharing mechanisms. Differences between the costs included in rates and the incurred costs, including undesignated derivative contracts, are largely deferred as regulatory assets or regulatory liabilities. Piedmont policies allow for the use of financial instruments to hedge commodity price risks. The strategy and objective of these hedging programs are to use the financial instruments to reduce natural gas cost volatility for customers.

Volumes

The tables below include volumes of outstanding commodity derivatives. Amounts disclosed represent the absolute value of notional volumes of commodity contracts excluding NPNS. The Duke Energy Registrants have netted contractual amounts where offsetting purchase and sale contracts exist with identical delivery locations and times of delivery. Where all commodity positions are perfectly offset, no quantities are shown.

FOREIGN CURRENCY RISK

Duke Energy may enter into foreign currency derivatives to hedge exposure to changes in foreign currency exchange rates, such as that arising from the issuance of debt denominated in a currency other than U.S. dollars.


FINANCIAL STATEMENTS			DERIVATIVES AND HEDGING

Fair Value Hedges

Derivatives related to existing ~~fixed rate~~fixed-rate securities are accounted for as fair value hedges, where the derivatives’ fair value gains or losses and hedged items’ fair value gains or losses are both recorded directly to earnings on the same income statement line item, including foreign currency gains or losses arising from changes in the U.S. currency exchange rates. Duke Energy has elected to exclude the cross-currency basis spread from the assessment of effectiveness in the fair value hedges of its foreign currency risk and record any difference between the change in the fair value of the excluded components and the amounts recognized in earnings as a component of other comprehensive income or loss.

The following table shows Duke Energy's outstanding derivatives related to foreign currency risk at March 31, ~~2023.~~2024.

10. INVESTMENTS IN DEBT AND EQUITY SECURITIES

Duke Energy’s investments in debt and equity securities are primarily comprised of investments held in (i) the NDTF at Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida, (ii) the grantor trusts at Duke Energy Progress, Duke Energy Florida and Duke Energy Indiana related to OPEB plans and (iii) Bison. The Duke Energy Registrants classify investments in debt securities as Available for Sale (AFS) and investments in equity securities as fair value through net income (FV-NI).

For investments in debt securities classified as AFS, the unrealized gains and losses are included in other comprehensive income until realized, at which time they are reported through net income. For investments in equity securities classified as FV-NI, both realized and unrealized gains and losses are reported through net income. Substantially all of Duke Energy’s investments in debt and equity securities qualify for regulatory accounting, and accordingly, all associated realized and unrealized gains and losses on these investments are deferred as a regulatory asset or liability.

Duke Energy classifies the majority of investments in debt and equity securities as long term, unless otherwise noted.

Investment Trusts

The investments within the Investment Trusts are managed by independent investment managers with discretion to buy, sell and invest pursuant to the guidelines set forth by the investment manager agreements and trust agreements. The Duke Energy Registrants have limited oversight of the day-to-day management of these investments. As a result, the ability to hold investments in unrealized loss positions is outside the control of the Duke Energy Registrants. Accordingly, all unrealized losses associated with debt securities within the Investment Trusts are recognized immediately and deferred to regulatory accounts where appropriate.

Other AFS Securities

Unrealized gains and losses on all other AFS securities are included in other comprehensive income until realized, unless it is determined the carrying value of an investment has a credit loss. The Duke Energy Registrants analyze all investment holdings each reporting period to determine whether a decline in fair value is related to a credit loss. If a credit loss exists, the unrealized credit loss is included in earnings. There were no material credit losses as of March 31, ~~2023,~~2024, and December 31, ~~2022.~~2023.

Other Investments amounts are recorded in Other within Other Noncurrent Assets on the Condensed Consolidated Balance Sheets.

11. FAIR VALUE MEASUREMENTS

Fair value is the exchange price to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The fair value definition focuses on an exit price versus the acquisition cost. Fair value measurements use market data or assumptions market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs may be readily observable, corroborated by market data or generally unobservable. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. A midmarket pricing convention (the midpoint price between bid and ask prices) is permitted for use as a practical expedient.

Fair value measurements are classified in three levels based on the fair value hierarchy as defined by GAAP. Certain investments are not categorized within the fair value hierarchy. These investments are measured at fair value using the net asset value per share practical expedient. The net asset value is derived based on the investment cost, less any impairment, plus or minus changes resulting from observable price changes for an identical or similar investment of the same issuer.

Fair value accounting guidance permits entities to elect to measure certain financial instruments that are not required to be accounted for at fair value, such as equity method investments or the ~~company’s~~Company’s own debt, at fair value. The Duke Energy Registrants have not elected to record any of these items at fair value.

Valuation methods of the primary fair value measurements disclosed below are as follows.

Investments in equity securities

The majority of investments in equity securities are valued using Level 1 measurements. Investments in equity securities are typically valued at the closing price in the principal active market as of the last business day of the quarter. Principal active markets for equity prices include published exchanges such as the ~~NYSE~~New York Stock Exchange and Nasdaq Stock Market. Foreign equity prices are translated from their trading currency using the currency exchange rate in effect at the close of the principal active market. There was no after-hours market activity that was required to be reflected in the reported fair value measurements.

FINANCIAL STATEMENTS			FAIR VALUE MEASUREMENTS

Investments in debt securities

Most investments in debt securities are valued using Level 2 measurements because the valuations use interest rate curves and credit spreads applied to the terms of the debt instrument (maturity and coupon interest rate) and consider the counterparty credit rating. If the market for a particular fixed-income security is relatively inactive or illiquid, the measurement is Level 3.

Commodity derivatives

Commodity derivatives with clearinghouses are classified as Level 1. Commodity derivatives with observable forward curves are classified as Level 2. If forward price curves are not observable for the full term of the contract and the unobservable period had more than an insignificant impact on the valuation, the commodity derivative is classified as Level 3. In isolation, increases (decreases) in natural gas forward prices result in favorable (unfavorable) fair value adjustments for natural gas purchase contracts; and increases (decreases) in electricity forward prices result in unfavorable (favorable) fair value adjustments for electricity sales contracts. Duke Energy regularly evaluates and validates pricing inputs used to estimate the fair value of ~~natural gas~~certain commodity contracts by a market participant price verification procedure. This procedure provides a comparison of internal forward commodity curves to market participant generated curves.

Interest rate derivatives

Most over-the-counter interest rate contract derivatives are valued using financial models that utilize observable inputs for similar instruments and are classified as Level 2. Inputs include forward interest rate curves, notional amounts, interest rates and credit quality of the counterparties. Derivatives related to interest rate risk for the Commercial Renewables Disposal Groups are now classified as held for sale and are excluded from the following disclosures. See Note 2 for further information.

Foreign currency derivatives

Most over-the-counter foreign currency derivatives are valued using financial models that utilize observable inputs for similar instruments and are classified as Level 2. Inputs include forward foreign currency rate curves, notional amounts, foreign currency rates and credit quality of the counterparties.

Other fair value considerations

See Note 12 in Duke Energy's Annual Report on Form 10-K for the year ended December 31, ~~2022,~~2023, for a discussion of the valuation of goodwill and intangible assets.

CONSOLIDATED VIEs

The obligations of the consolidated VIEs discussed in the following paragraphs are nonrecourse to the Duke Energy Registrants. The registrants have no requirement to provide liquidity to, purchase assets of or guarantee performance of these VIEs unless noted in the following paragraphs.

No financial support was provided to any of the consolidated VIEs during the three months ended March 31, ~~2023,~~2024, and the year ended December 31, ~~2022,~~2023, or is expected to be provided in the future that was not previously contractually required.

Receivables Financing – DERF/DEPR/DEFR

DERF, DEPR and DEFR are bankruptcy remote, special purpose subsidiaries of Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida, respectively. DERF, DEPR and DEFR are wholly owned LLCs with separate legal existence from their parent companies, and their assets are not generally available to creditors of their parent companies. On a revolving basis, DERF, DEPR and DEFR buy certain accounts receivable arising from the sale of electricity and related services from their parent companies.

DERF, DEPR and DEFR borrow amounts under credit facilities to buy these receivables. Borrowing availability from the credit facilities is limited to the amount of qualified receivables purchased, which generally exclude receivables past due more than a predetermined number of days and reserves for expected past-due balances. The sole source of funds to satisfy the related debt obligations is cash collections from the receivables. Amounts borrowed under the DEPR credit facility are reflected on the Condensed Consolidated Balance Sheets as Long-Term Debt. Amounts borrowed under the DERF and DEFR credit facilities are reflected on the Condensed Consolidated Balance Sheets as Current maturities of long-term debt.

The most significant activity that impacts the economic performance of DERF, DEPR and DEFR are the decisions made to manage delinquent receivables. Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida are considered the primary beneficiaries and consolidate DERF, DEPR and DEFR, respectively, as they make those decisions.

In April 2024, Duke Energy Florida repaid all outstanding DEFR borrowings totaling $325 million and terminated the related DEFR credit facility. Additionally, Duke Energy Florida's related restricted receivables outstanding at DEFR at the time of termination totaled $459 million and were transferred back to Duke Energy Florida to be collected and reported as Receivables on the Condensed Consolidated Balance Sheets.

Receivables Financing – CRC

CRC is a bankruptcy remote, special purpose entity indirectly owned by Duke Energy. On a revolving basis, CRC ~~buys~~bought certain accounts receivable arising from the sale of electricity, natural gas and related services from Duke Energy Ohio and Duke Energy Indiana. CRC ~~borrows~~then borrowed amounts under a credit facility to buy the receivables from Duke Energy Ohio and Duke Energy Indiana. Borrowing availability from the credit facility iswas limited to the amount of qualified receivables sold to CRC, which generally ~~exclude~~excluded receivables past due more than a predetermined number of days and ~~reserves~~reserved for expected past-due balances. The sole source of funds to satisfy the related debt obligation iswas cash collections from the receivables. ~~Amounts borrowed under the credit facility are reflected on Duke Energy's Condensed Consolidated Balance Sheets as Long-Term Debt.~~

The proceeds Duke Energy Ohio and Duke Energy Indiana ~~receive~~received from the sale of receivables to CRC ~~are~~were approximately 75% cash and 25% in the form of a subordinated note from CRC. The subordinated note iswas a retained interest in the receivables sold. Depending on collection experience, additional equity infusions to CRC ~~may~~would be required by Duke Energy to maintain a minimum equity balance of $3 million.


FINANCIAL STATEMENTS			VARIABLE INTEREST ENTITIES

CRC iswas considered a VIE because (i) equity capitalization iswas insufficient to support its operations, (ii) power to direct the activities that most significantly impact the economic performance of the entity iswas not held by the equity holder and (iii) deficiencies in net worth of CRC ~~are~~were funded by Duke Energy. The most significant activities that ~~impact~~impacted the economic performance of CRC ~~are~~were decisions made to manage delinquent receivables. Duke Energy iswas considered the primary beneficiary and ~~consolidates~~consolidated CRC as it ~~makes~~made these decisions. Neither Duke Energy Ohio nor Duke Energy Indiana ~~consolidate~~consolidated CRC.


~~FINANCIAL STATEMENTS~~			~~VARIABLE INTEREST ENTITIES~~

In March 2024, Duke Energy repaid all outstanding CRC borrowings totaling $350 million and terminated the related CRC credit facility. Additionally, Duke Energy's related restricted receivables outstanding at CRC at the time of termination totaled $682 million, consisting of $316 million and $366 million of restricted receivables that were transferred back to Duke Energy Indiana and Duke Energy Ohio, respectively, to be collected and reported as Receivables on the Condensed Consolidated Balance Sheets.

The Duke Energy Registrants are not aware of any situations where the maximum exposure to loss significantly exceeds the carrying values shown above.

Natural Gas Investments

Duke Energy has investments in various joint ventures including pipeline and renewable natural gas projects. These entities are considered VIEs due to having insufficient equity to finance their own activities without subordinated financial support. Duke Energy does not have the power to direct the activities that most significantly impact the economic performance, the obligation to absorb losses or the right to receive benefits of these VIEs and therefore does not consolidate these entities.

CRC

See discussion under Consolidated VIEs for additional information related to CRC.

13. REVENUE

Duke Energy earns substantially all of its revenues through its reportable segments, EU&I and GU&I.

Electric Utilities and Infrastructure

EU&I earns the majority of its revenues through retail and wholesale electric service through the generation, transmission, distribution and sale of electricity. Duke Energy generally provides retail and wholesale electric service customers with their full electric load requirements or with supplemental load requirements when the customer has other sources of electricity.

The majority of wholesale revenues are full requirements contracts where the customers purchase the substantial majority of their energy needs and do not have a fixed quantity of contractually required energy or capacity. As such, related forecasted revenues are considered optional purchases. Supplemental requirements contracts that include contracted blocks of energy and capacity at contractually fixed prices have the following estimated remaining performance obligations:

Revenues for block sales are recognized monthly as energy is delivered and stand-ready service is provided, consistent with invoiced amounts and unbilled estimates.

Gas Utilities and Infrastructure

GU&I earns its revenue through retail and wholesale natural gas service through the transportation, distribution and sale of natural gas. Duke Energy generally provides retail and wholesale natural gas service customers with all natural gas load requirements. Additionally, while natural gas can be stored, substantially all natural gas provided by Duke Energy is consumed by customers simultaneously with receipt of delivery.

Fixed-capacity payments under long-term contracts for the GU&I segment include minimum margin contracts and supply arrangements with municipalities and power generation facilities. Revenues for related sales are recognized monthly as natural gas is delivered and stand-ready service is provided, consistent with invoiced amounts and unbilled estimates. Estimated remaining performance obligations are as follows:

Trade and other receivables are evaluated based on an estimate of the risk of loss over the life of the receivable and current and historical conditions using supportable assumptions. Management evaluates the risk of loss for trade and other receivables by comparing the historical write-off amounts to total revenue over a specified period. Historical loss rates are adjusted due to the impact of current conditions, as well as forecasted conditions over a reasonable time period. The calculated write-off rate can be applied to the receivable balance for which an established reserve does not already exist. Management reviews the assumptions and risk of loss periodically for trade and other receivables.

14. STOCKHOLDERS' EQUITY

Basic EPS is computed by dividing net income available to Duke Energy common stockholders, as adjusted for distributed and undistributed earnings allocated to participating securities and accumulated preferred dividends, by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income available to Duke Energy common stockholders, as adjusted for distributed and undistributed earnings allocated to participating securities and accumulated preferred dividends, by the diluted weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other agreements to issue common stock, such as equity forward sale agreements or convertible debt, were exercised or settled. Duke Energy applies the if-converted method for calculating any potential dilutive effect of the conversion of the outstanding convertible notes on diluted EPS, if applicable. Duke Energy’s participating securities are restricted stock units that are entitled to dividends declared on Duke Energy common stock during the restricted stock unit’s vesting periods. Dividends declared on preferred stock are recorded on the Condensed Consolidated Statements of Operations as a reduction of net income to arrive at net income available to Duke Energy common stockholders. Dividends accumulated on preferred stock are an adjustment to net income used in the calculation of basic and diluted EPS.

Common Stock

In November 2022, Duke Energy filed a prospectus supplement and executed an Equity Distribution Agreement (EDA) under which it may sell up to $1.5 billion of its common stock through an at-the-market (ATM) offering program, including an equity forward sales component. Under the terms of the EDA, Duke Energy may issue and sell shares of common stock through September 2025.

In March 2024, Duke Energy marketed its first tranche, issuing 0.8 million shares of common stock through an equity forward transaction under the ATM program with an initial forward price of $92.77 per share. The equity forward requires Duke Energy to either physically settle the transaction by issuing shares in exchange for net proceeds at the then-applicable forward sale price specified by the agreements or net settle in whole or in part through the delivery or receipt of cash or shares. The settlement alternative is at Duke Energy's election. No amounts have or will be recorded in Duke Energy's Condensed Consolidated Financial Statements with respect to the ATM offering until settlement of the equity forward occurs, which is expected during or prior to December 2024. The initial forward sale price will be subject to adjustment on a daily basis based on a floating interest rate factor and will decrease by other fixed amounts specified in the relevant forward sale agreement. Until settlement of the equity forward, earnings per share dilution resulting from the agreement, if any, will be determined under the treasury stock method.

16. INCOME TAXES

On August 16, 2022, the IRA was signed into law. Among other provisions, the IRA created a new, zero-emission nuclear power PTC available for taxpayers beginning January 1, 2024. In the first quarter of 2024, Duke Energy Carolinas and Duke Energy Progress recorded a PTC deferred tax asset of approximately $107 million and $14 million, respectively. These amounts represent the net realizable value of the PTCs, which were deferred to a regulatory liability. The Subsidiary Registrants will work with the state utility commissions on the best regulatory process to pass the net realizable value back to customers over time. See Note 4 for additional information on Duke Energy Carolinas' approval for a stand-alone rider starting January 1, 2025. The Company will continue to assess its calculations and interpretations as new information and guidance becomes available.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following combined Management’s Discussion and Analysis of Financial Condition and Results of Operations is separately filed by Duke Energy and Duke Energy Carolinas, Progress Energy, Duke Energy Progress, Duke Energy Florida, Duke Energy Ohio, Duke Energy Indiana and Piedmont. However, none of the registrants make any representation as to information related solely to Duke Energy or the Subsidiary Registrants of Duke Energy other than itself.

DUKE ENERGY

Duke Energy is an energy company headquartered in Charlotte, North Carolina. Duke Energy operates in the U.S. primarily through its subsidiaries, Duke Energy Carolinas, Duke Energy Progress, Duke Energy Florida, Duke Energy Ohio, Duke Energy Indiana and Piedmont. When discussing Duke Energy’s consolidated financial information, it necessarily includes the results of the Subsidiary Registrants, which along with Duke Energy are collectively referred to as the Duke Energy Registrants.

Management’s Discussion and Analysis should be read in conjunction with the Condensed Consolidated Financial Statements and Notes for the three months ended March 31, ~~2023,~~2024, and with Duke Energy’s Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023.

Executive Overview

Advancing Our Clean Energy ~~Transformation~~

Transition. During the ~~first quarter of 2023,~~three months ended March 31, 2024, we continued to execute on our clean energy ~~transformation,~~transition, remaining focused on reliability and affordability while delivering increasingly clean energy and providing strong, sustainable value for shareholders, customers, communities and employees.

•In November 2022, the Board approved pursuing the sale of the Commercial Renewables business, excluding the offshore wind contract for Carolina Long Bay. We are continuing to market the business through three disposal groups. As we look forward to the remainder of this decade and beyond, we have line of sight to significant renewable, grid and other investment opportunities within our faster-growing regulated operations. We expect to dispose of these groups in the second half of 2023. See Note 2 to the Condensed Consolidated Financial Statements, "Dispositions," for additional information.

•In January 2024, we filed supplemental modeling and analysis with the NCUC and PSCSC related to our combined systemwide Carolinas Resource Plan filed in August 2023. These updates were necessary due to substantially increased load forecasts resulting from continued economic development successes in the Carolinas occurring since the systemwide integrated resource plan was prepared. In March ~~2023,~~2024, we ~~began operating~~filed for CPCNs for new generation facilities at the ~~largest~~sites of the current Marshall Steam Station and Roxboro Plant in the Carolinas. Our energy transition strategy continues to focus on delivering a path to cleaner energy in a manner that protects grid reliability and affordability, all while meeting the energy demands of the growing and economically vibrant communities that we serve.

•As we continue to strengthen our grid and bring clean energy resources online, our customers are important partners in our clean energy future. In January 2024, we received approval for PowerPairSM, a new incentive-based pilot program for installing home solar generation with battery ~~system~~energy storage in North Carolina, an 11-MW project in Onslow County, which will operate in conjunction with an adjacent 13-MW solar facility located on a leased site within Marine Corps Base (MCB) Camp Lejeune. Both projects are connected to aour Duke Energy ~~substation~~Carolinas and ~~will be used to serve all~~ Duke Energy Progress ~~customers. As part~~North Carolina service territories. Enrollment options for residential customers that participate in the pilot include a one-time incentive of ~~an ongoing collaboration with~~up to $9,000 for the ~~Department~~installation of ~~Defense, further work could enable the~~a solar ~~and~~plus battery ~~systems to improve the resiliency of MCB Camp Lejeune against outages.~~

•In March 2023, Duke Energy Florida announced two new solar projects as part of Clean Energy Connection, the company's community solar program. Once complete, each 74.9-MW solar facility will generate enough carbon-free electricity to power what would be the equivalent to around 23,000 homes. Additionally, in March 2023, Duke Energy Florida announced its first floating solar array pilot. The project will feature more than 1,800 floating solar modules and occupy approximately 2 acres of water surface on an existing cooling pond at the Duke Energy Hines Energy Complex in Bartow. The pilot is part of Duke Energy's Vision Florida program, which is designed to test innovative projects such as microgrids and battery energy storage, among others, to prepare the power grid for a clean energy future.

Regulatory Activity. During the ~~first quarter of 2023,~~three months ended March 31, 2024, we continued to ~~monitor developments while moving~~move our regulatory strategy forward. See Note 4 to the Condensed Consolidated Financial Statements, "Regulatory Matters," for additional information.

•In ~~February 2023,~~April 2024, we filed formal requests for new base rates across several jurisdictions including Duke Energy Florida, Duke Energy Indiana and Piedmont.

•Duke Energy Florida filed a three-year rate plan that would begin in January 2025, once its current base rate settlement agreement concludes at the ~~PSCSC approved~~end of 2024, and proposed approximately $4.9 billion in investments to reduce outages, expand solar generation, and increase generation unit efficiency. The overall additional base rate revenue requirement would be $820 million over the three-year period and, if approved by the FPSC, will facilitate improved grid reliability for a ~~constructive comprehensive settlement~~growing customer base, reduced fuel consumption at existing power plants, and the construction of 14 new solar plants, providing 1,050 MW of clean energy to Florida's grid.

•Duke Energy Indiana filed a general rate case with ~~all parties~~the IURC requesting an overall increase in revenues of $492 million. This is the first base rate case filed by Duke Energy Indiana since 2019 and reflects strategic investments to improve grid reliability and security, serve a growing customer base, and meet environmental regulations. These investments, which include approximately 345 miles of new power lines expected to be constructed through 2025, will support the more than 60,000 new customers anticipated since our last base rate case.

•Piedmont filed a general rate case with the NCUC requesting an overall increase in revenues of $159 million. This is the first base rate case filed by Piedmont in North Carolina since 2021 and reflects significant investments to support ongoing service reliability, system growth, and compliance with federal pipeline safety regulations in addition to two energy reliability centers in eastern North Carolina.

•Also, in April 2024, Duke Energy Progress issued $177 million of storm recovery bonds, our first issuance under South ~~Carolina rate case. Duke Energy Progress implemented new customer rates effective April 1, 2023.~~

Matters Impacting Future Results

The matters discussed herein could materially impact the future operating results, financial condition and cash flows of the Duke Energy Registrants and Business Segments.


MD&A			MATTERS IMPACTING FUTURE RESULTS

Regulatory Matters

Coal Ash Costs

Future spending of coal ash costs, including amounts recorded for depreciation and liability accretion, is expected to be recovered in future rate cases or rider filings. The majority of spend is expected to occur over the next 10 ~~to 15~~ years.

In response to the letter, Duke Energy Indiana has submitted revised closure plans for those basins to the Indiana Department of Environmental Management (IDEM). Those closure plans are pending review by IDEM. See NotesNote 4 ~~and 5~~ to the Condensed Consolidated Financial Statements, "Regulatory ~~Matters" and "Commitments and Contingencies,~~Matters." ~~respectively, for more information.~~

Fuel Cost Recovery

As a result of rapidly rising commodity costs during 2022, including natural gas, fuel and purchased power prices in excess of amounts included in fuel-related revenues ~~has~~ led to an increase in the under collection of fuel costs from customers ~~at certain~~in jurisdictions including Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida. These amounts have been deferred in regulatory assets and ~~have~~ impacted the cash flows of the registrants, including increased borrowings to temporarily finance related expenditures until recovery. Regulatory filings have been made and approved for recovery of all remaining uncollected 2022 fuel costs. Across all jurisdictions, Duke Energy is currently on pace to recover approximately $1.9 billion of deferred fuel costs in 2024.We anticipate being in line with our historical average balance of deferred fuel costs by the end of this year.

Environmental Regulations

In April 2024, the EPA issued a final rule under the Resource Conservation and Recovery Act, which significantly expands the scope of the CCR Rule by establishing regulatory requirements for inactive surface impoundments at retired generating facilities and previously unregulated coal ash sources at regulated facilities. The EPA also issued a final rule under section 111 of the Clean Air Act regulating GHG emissions from existing coal-fired and new natural gas-fired power plants. Duke Energy is reviewing these final rules and analyzing the potential impacts they could have on the Company, which could be material. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of necessary and prudently incurred costs associated with Duke Energy’s regulated operations. Duke Energy is evaluating potential legal challenges to the final rules. For more information, see "Other Matters."

Supply Chain

The Company continues to monitor the ongoing stability of markets for key materials and other developments, including public policy outcomes, that could disrupt or impact the Company's supply chain and, as a result, may impact Duke Energy's execution of its capital plan, future financial results or the achievement of its clean energy goals.

Goodwill

The Duke Energy Registrants ~~are working with various state commissions~~performed their annual goodwill impairment tests as of August 31, 2023. As of this date, all of the Duke Energy Registrants' reporting units' estimated fair values materially exceeded the carrying values except for the GU&I reporting unit of Duke Energy Ohio. While no goodwill impairment charges were recorded in 2023, the potential for continued interest rate pressures, and the related impact on the ~~timing~~weighted average cost of ~~recovery of these amounts.~~

~~Commercial Renewables~~

In November 2022, Duke Energy committed to a plan to sell the Commercial Renewables Disposal Groups. The Commercial Renewables Disposal Groups were classified as held for sale and as discontinued operations in the fourth quarter of 2022. Marketing of the disposal groups continues and Duke Energy expects to complete the sales of the disposal groups in the second half of 2023. If necessary, the loss on the sale of the assets will be updated based on market changescapital, without timely or the final sales price, including all closing adjustments, and could be materially different than the estimated loss. Additionally, certain other costs resulting from the transactions may be recognized in the period incurred. Proceeds from the sales are expected to be used for debt avoidance. For more information, see Note 2adequate updates to the ~~Consolidated Financial Statements, "Dispositions."~~

~~In February 2021, a severe winter storm impacted certain Commercial Renewables assets in Texas. Extreme weather~~regulated allowed return on equity or deteriorating economic conditions ~~limited the ability for these solar and wind facilities to generate and sell electricity into the ERCOT market. Duke Energy (Parent) has been named in multiple lawsuits arising out~~impacting GU&I's future cash flows or equity valuations of this winter storm. The legal actions against Duke Energy (Parent) related to these lawsuits will remain with Duke Energy (Parent) and any future activity related to Duke Energy (Parent) as a defendant in these lawsuits will be presented in discontinued operations. For more information, see Note 5 to the Condensed Consolidated Financial Statements, "Commitments and Contingencies."

Results of Operations

Non-GAAP Measures

Management’s Discussion and Analysis includes financial information prepared in accordance with GAAP in the U.S., as well as certain non-GAAP financial measures, adjusted earnings and adjusted EPS, discussed below. Non-GAAP financial measures are numerical measures of financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. Non-GAAP financial measures should be viewed as a supplement to, and not a substitute for, financial measures presented in accordance with GAAP. Non-GAAP measures presented may not be comparable to similarly titled measures used by other companies because other companies may not calculate the measures in the same manner.

Management evaluates financial performance in part based on non-GAAP financial measures, including adjusted earnings and adjusted EPS. Adjusted earnings and adjusted EPS represent income from continuing operations available to Duke Energy Corporation common stockholders in dollar and per share amounts, adjusted for the dollar and per share impact of special items. As discussed below, special items represent certain charges and credits, which management believes are not indicative of Duke Energy's ongoing performance. The most directly comparable GAAP measures for adjusted earnings and adjusted EPS are GAAP Reported Earnings (Loss) and GAAP Reported Earnings (Loss) Per Share, respectively.

~~Special items included in the periods presented below include the following, which management believes do not reflect ongoing costs:~~

•~~Regulatory Matters~~Discontinued operations primarily represents the ~~net impact of~~ ~~charges~~operating results and impairments recognized related to the ~~2022 Indiana Supreme Court ruling on coal ash.~~sale of the Commercial Renewables business disposal group.

LIQUIDITY AND CAPITAL RESOURCES

Sources and Uses of Cash

Duke Energy relies primarily upon cash flows from operations, debt and equity issuances and its existing cash and cash equivalents to fund its liquidity and capital requirements. Duke Energy’s capital requirements arise primarily from capital and investment expenditures, repaying long-term debt and paying dividends to shareholders. Additionally, due to its existing tax attributes and projected tax credits to be generated relating to the IRA, Duke Energy does not expect to be a significant federal cash taxpayer until around 2030. Duke Energy’s Annual Report on Form 10-K for the year ended December 31, ~~2022,~~2023, included a summary and detailed discussion of projected primary sources and uses of cash for ~~2023~~2024 to ~~2025.~~2026.

As part of the ATM program, in March 2024, Duke Energy executed an equity forward sales agreement. Settlement of the forward sales agreement is expected to occur during or prior to December 2024. See Note 14 to the Condensed Consolidated Financial Statements, “Stockholders’ Equity” for further details.

As of March 31, ~~2023,~~2024, Duke Energy had ~~approximately $451~~$459 million of cash on hand and ~~$5.4~~$5.1 billion available under its $9 billion Master ~~Credit~~Credit Facility. Duke Energy expects to have sufficient liquidity in the form of cash on hand, cash from operations and available credit capacity to support its funding needs.

As discussed in Note 12 to the Condensed Consolidated Financial Statements, "Variable Interest Entities," Duke Energy terminated and repaid CRC in March 2024 and Duke Energy Florida terminated and repaid DEFR in April 2024. As a result of these repayments, CRC and DEFR have ceased operations and no longer acquire the receivables of Duke Energy’s subsidiaries. Duke Energy Carolinas and Duke Energy Progress continue to evaluate financing opportunities and anticipate termination and repayment of the borrowing facilities of DERF and DEPR prior to their scheduled termination dates in January 2025 and April 2025, respectively.

OTHER MATTERS

Environmental Regulations

The Duke Energy Registrants are subject to federal, state and local regulations regarding air and water quality, hazardous and solid waste disposal, coal ash and other environmental matters. These regulations can be changed from time to time and result in new obligations of the Duke Energy Registrants. Refer to Note 4, "Regulatory Matters," in Duke Energy's Annual Report on Form 10-K for the year ended December 31, ~~2022,~~2023, for more information regarding potential plant retirements and Note 4, "Regulatory Matters," to the Condensed Consolidated Financial Statements, for further information regarding regulatory filings related to the Duke Energy Registrants.

In April 2024, the EPA issued a final rule under the Resource Conservation and Recovery Act, which significantly expands the scope of the CCR Rule by establishing regulatory requirements for inactive surface impoundments at retired generating facilities (Legacy CCR Surface Impoundments). The final rule also imposes a subset of the CCR Rule’s requirements, including groundwater monitoring, corrective action (where necessary), and in certain cases, closure, and post-closure care requirements, on previously unregulated coal ash sources at regulated facilities (CCR Management Units). CCR Management Units may include surface impoundments and landfills that closed prior to the effective date of the 2015 CCR Rule, inactive CCR landfills, and other areas where CCR is managed directly on the land at Duke Energy facilities. Duke Energy is reviewing the final rule and analyzing the potential impacts it could have on the Company, which could be material.

In April 2024, the EPA issued a final rule under section 111 of the Clean Air Act (EPA Rule 111) regulating GHG emissions from existing coal-fired and new natural gas-fired power plants, referred to as electric generating units (EGUs). EPA Rule 111 requires existing coal-fired power plants expected to operate in 2039 and beyond to reduce GHG emissions by 90% through the use of carbon capture and sequestration starting in 2032, subject to certain modifications for coal plants that retire sooner and co-fire natural gas. EPA Rule 111 also establishes GHG emissions reduction standards for new natural gas-fired EGUs, subject to carve-outs for smaller peaking units that fill gaps that cannot be met with renewables or storage. The EPA did not finalize emission guidelines for GHG emissions from existing fossil fuel-fired stationary combustion turbines and intends to address these is a future rulemaking. Duke Energy is reviewing the final rule and analyzing the potential impacts it could have on the Company, which could be material.

Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of necessary and prudently incurred costs associated with Duke Energy’s regulated operations. Duke Energy is evaluating potential legal challenges to the final rules.

OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Duke Energy Registrants are, from time to time, parties to various lawsuits and regulatory proceedings in the ordinary course of their business. For information regarding legal proceedings, including regulatory and environmental matters, see Note 4, "Regulatory Matters," and Note 5, "Commitments and Contingencies," to the Condensed Consolidated Financial Statements. For additional information, see Item 3, "Legal Proceedings," in Duke Energy's Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, careful consideration should be given to the factors discussed in Part I, “Item 1A. Risk Factors” in the Duke Energy's Annual Report on Form 10-K for the year ended December 31, ~~2022,~~2023, which could materially affect the Duke Energy Registrants’ financial condition or future results. The information presented below updates, and should be read in conjunction with, the risk factors and information disclosed in Duke Energy's Annual Report on Form 10-K for the year ended December 31, 2023.

BUSINESS STRATEGY RISKS

Duke Energy’s future results could be adversely affected if it is unable to implement its business strategy including achieving its carbon emissions reduction goals.

Duke Energy’s results of operations depend, in significant part, on the extent to which it can implement its business strategy successfully. Duke Energy's clean energy transition, which includes achieving net-zero carbon emissions from electricity generation by 2050, modernizing the regulatory construct, transforming the customer experience, and digital transformation, is subject to business, policy, regulatory, technology, economic and competitive uncertainties and contingencies, many of which are beyond its control and may make those goals difficult to achieve.

Federal or state policies could be enacted that restrict the availability of, and increase the costs associated with the use of, fuels or generation technologies, such as natural gas or nuclear power, that enable Duke Energy to reduce its carbon emissions. For example, new EPA rules issued in April 2024 impose stringent GHG emission reduction standards, revised air toxic limits, and wastewater discharge limitations that may impact our carbon-reduction targets, and operational timeline and costs associated with certain new and existing generation. Supportive policies may be needed to facilitate the siting and cost recovery of transmission and distribution upgrades needed to accommodate the build out of large volumes of renewables and energy storage. Further, the approval of our state regulators will be necessary for the Company to continue to retire existing carbon emitting assets or make investments in new generating capacity. The Company may be constrained by the ability to procure resources or labor needed to build new generation at a reasonable price as well as to construct projects on time. In addition, new technologies that are not yet commercially available or are unproven at utility-scale will likely be needed, including carbon capture and sequestration and supporting infrastructure as well as new resources capable of following electric load over long durations such as advanced nuclear, hydrogen and long-duration storage. If these technologies are not developed or are not available at reasonable prices, or if we invest in early stage technologies that are then supplanted by technological breakthroughs, Duke Energy’s ability to achieve a net-zero target by 2050 at a cost-effective price could be at risk.

Achieving our carbon reduction goals will require continued operation of our existing carbon-free technologies including nuclear and renewables. The rapid transition to and expansion of certain low-carbon resources, such as renewables without cost-effective storage, may challenge our ability to meet customer expectations of reliability and affordability in a carbon constrained environment, particularly as demand increases. Our nuclear fleet is central to our ability to meet these objectives and customer expectations. We are continuing to seek to renew the operating licenses of the 11 reactors we operate at six nuclear stations for an additional 20 years, extending their operating lives to and beyond midcentury. Failure to receive approval from the NRC for the relicensing of any of these reactors could affect our ability to achieve a net-zero target by 2050.

As a consequence, Duke Energy may not be able to fully implement or realize the anticipated results of its energy transition strategy, which may have an adverse effect on its financial condition.

OTHER INFORMATION

REGULATORY, LEGISLATIVE AND LEGAL RISKS

The Duke Energy Registrants are subject to numerous environmental laws and regulations requiring significant capital expenditures that can increase the cost of operations, and which may impact or limit business plans, or cause exposure to environmental liabilities.

The Duke Energy Registrants are subject to numerous environmental laws and regulations affecting many aspects of their present and future operations, including CCRs, air emissions, water quality, wastewater discharges, solid waste and hazardous waste. For example, the new EPA rules issued in April 2024, among other things, impose stringent GHG emissions limitations on existing coal plants and new natural gas plants and more stringent air toxic limits on existing coal plants, increase limitations on wastewater discharge, and impose groundwater monitoring and corrective action requirements on previously unregulated coal ash sources at regulated facilities (CCR Management Units) and inactive surface impoundments at retired generating facilities (Legacy CCR Surface Impoundments). Potential legal challenges to such rules may not be successful, and adherence to these rules may increase the cost of compliance, impact generation resource mix and carbon-reduction targets, and negatively impact customer reliability and affordability due to such rules' imposition of stringent GHG emissions limitations and reliance on carbon capture technologies that are not yet adequately demonstrated at utility-scale. These and other environmental laws and regulations can result in increased capital, operating and other costs. These laws and regulations generally require the Duke Energy Registrants to obtain and comply with a wide variety of environmental licenses, permits, inspections and other approvals. Compliance with environmental laws and regulations can require significant expenditures, including expenditures for cleanup costs and damages arising from contaminated properties. Failure to comply with environmental regulations may result in the imposition of fines, penalties and injunctive measures affecting operating assets, as well as reputational damage. The steps the Duke Energy Registrants could be required to take to ensure their facilities are in compliance could be prohibitively expensive. As a result, the Duke Energy Registrants may be required to shut down or alter the operation of their facilities, which may cause the Duke Energy Registrants to incur losses. Further, the Duke Energy Registrants may not be successful in recovering capital and operating costs incurred to comply with new environmental regulations through existing regulatory rate structures and their contracts with customers. Also, the Duke Energy Registrants may not be able to obtain or maintain from time to time all required environmental regulatory approvals for their operating assets or development projects. Delays in obtaining any required environmental regulatory approvals, failure to obtain and comply with them or changes in environmental laws or regulations to more stringent compliance levels could, and are likely to, result in additional costs of operation for existing facilities or development of new facilities being prevented, delayed or subject to additional costs. The costs to comply with environmental laws and regulations could have a material effect on the Duke Energy Registrants’ results of operations, financial position or cash flows.

The EPA has issued or proposed federal regulations, including the new rules issued in April 2024, governing the management of cooling water intake structures, wastewater, CCR management units, air toxics emissions, and CO2 emissions. New state legislation in response to such regulations could impose carbon reduction goals that are more aggressive than the Company's plans. These regulations may require the Duke Energy Registrants to make additional capital expenditures and increase operating and maintenance costs.

OPERATIONAL RISKS

The reputation and financial condition of the Duke Energy Registrants could be negatively impacted due to their obligations to comply with federal and state regulations, laws, and other legal requirements that govern the operations, assessments, storage, closure, remediation, disposal and monitoring relating to CCR, the high costs and new rate impacts associated with implementing these new CCR-related requirements and the strategies and methods necessary to implement these requirements in compliance with these legal obligations.

As a result of electricity produced for decades at coal-fired power plants, the Duke Energy Registrants manage large amounts of CCR that are primarily stored in dry storage within landfills or combined with water in surface impoundments, all in compliance with applicable regulatory requirements. A CCR-related operational incident could have a material adverse impact on the reputation and results of operations, financial position and cash flows of the Duke Energy Registrants.

During 2015, EPA regulations were enacted related to the management of CCR from power plants. These regulations classify CCR as nonhazardous waste under the RCRA and apply to electric generating sites with new and existing landfills and, new and existing surface impoundments, and establish requirements regarding landfill design, structural integrity design and assessment criteria for surface impoundments, groundwater monitoring, protection and remedial procedures and other operational and reporting procedures for the disposal and management of CCR. In addition to the federal regulations, CCR landfills and surface impoundments will continue to be regulated by existing state laws, regulations and permits, as well as additional legal requirements that may be imposed in the future, such as the settlement reached with the NCDEQ to excavate seven of the nine remaining coal ash basins in North Carolina, and partially excavate the remaining two, and the EPA's January 11, 2022, issuance of a letter interpreting the CCR Rule, including its applicability and closure provisions. Most recently, in April 2024, the EPA issued its final Legacy Surface Impoundment Rule, which significantly expands the scope of the 2015 CCR Rule to apply to legacy CCR surface impoundments (inactive impoundments at retired facilities) and CCR management units (previously unregulated coal ash sources at regulated facilities). These federal and state laws, regulations and other legal requirements may require or result in additional expenditures, including increased operating and maintenance costs, which could affect the results of operations, financial position and cash flows of the Duke Energy Registrants. The Duke Energy Registrants will continue to seek full cost recovery for expenditures through the normal ratemaking process with state and federal utility commissions, who permit recovery in rates of necessary and prudently incurred costs associated with the Duke Energy Registrants’ regulated operations, and through other wholesale contracts with terms that contemplate recovery of such costs, although there is no guarantee of full cost recovery. In addition, the timing for and amount of recovery of such costs could have a material adverse impact on Duke Energy's cash flows.

The Duke Energy Registrants have recognized significant AROs related to these CCR-related requirements. Closure activities began in 2015 at the four sites specified as high priority by the Coal Ash Act and at the W.S. Lee Steam Station site in South Carolina in connection with other legal requirements. Excavation at these sites involves movement of CCR materials to off-site locations for use as structural fill, to appropriately engineered off-site or on-site lined landfills or conversion of the ash for beneficial use. Duke Energy has completed excavation of coal ash at the four high-priority North Carolina sites. At other sites, planning and closure methods have been studied and factored into the estimated retirement and management costs, and closure activities have commenced. As the closure and CCR management work progresses and final closure plans and corrective action measures are developed and approved at each site, the scope and complexity of work and the amount of CCR material could be greater than estimates and could, therefore, materially increase compliance expenditures and rate impacts.
