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 meeting forecasted load growth demand, grid and fleet modernization objectives, and our carbon emission reduction goals, while balancing customer reliability and affordability;

◦ State, federal and foreign legislative and regulatory initiatives, including costs of compliance with existing and future environmental requirements and/or uncertainty of applicability or changes to such legislative and regulatory initiatives, 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 timely 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 a global pandemic, trade wars or military conflict, 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 decline in service territories or customer bases resulting from sustained downturns of the economy, storm damage, reduced customer usage due to cost pressures from inflation, tariffs, or fuel costs, worsening economic health of our service territories, reductions in customer usage patterns, or lower than anticipated load growth, particularly if usage of electricity by data centers is less than currently projected, 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, including artificial intelligence;

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

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

◦ Changing or conflicting investor, customer and other stakeholder expectations and demands, particularly regarding environmental, social and governance matters 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 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 severe storms, 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, including any impact from increased tariffs, export controls and interest rates, and the ability to timely 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 portfolio, 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 and recover on claims made;

◦ 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 businesses and the success of efforts to invest in and develop new 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 investment carrying values;

◦ Asset or business acquisitions and dispositions may not be consummated or yield the anticipated benefits, which could adversely affect our financial condition, credit metrics or ability to execute strategic and capital plans; 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 an obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

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 Duke Energy's Annual Report on Form 10-K for the year ended December 31, 2024.

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 13 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. For all periods presented, unless otherwise noted, disclosures related to balance sheet activity exclude amounts presented as held for sale and disclosures related to income statement activity exclude amounts related to discontinued operations. A portion of NCI on Duke Energy's Condensed Consolidated Balance Sheet as of December 31, 2024, relates to discontinued operations. See Note 2 for discussion of discontinued operations related to the Commercial Renewables Disposal Groups.

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 11 and 13 for additional information. Restricted cash amounts are included in Other within Current Assets and Other within Noncurrent Assets on the Condensed Consolidated Balance Sheets. The following table presents the components of cash, cash equivalents and restricted cash included on the Condensed Consolidated Balance Sheets.

OTHER NONCURRENT ASSETS

Duke Energy, through a nonregulated subsidiary, was the winner of the Carolina Long Bay offshore wind auction in May 2022. The cost of the rights acquired from the auction, totaling $ 150 million, is recorded in Other within Other noncurrent assets on Duke Energy's Condensed Consolidated Balance Sheets as of September 30, 2025, and December 31, 2024.

ACCOUNTS PAYABLE

Duke Energy has a voluntary supply chain finance program (the “program”) that allows Duke Energy suppliers, at their sole discretion, to sell their receivables from Duke Energy to 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’s payment terms, which are based on commercial terms negotiated between Duke Energy and the supplier regardless of program participation. 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.


FINANCIAL STATEMENTS			ORGANIZATION AND BASIS OF PRESENTATION

The following table presents the amounts included within Accounts payable on the Condensed Consolidated Balance Sheets sold to the financial institution by our suppliers and the supplier invoices sold to the financial institution under the program included within Net cash provided by operating activities on the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2025, and 2024.

NEW ACCOUNTING STANDARDS

The following new accounting standards have been issued but not yet adopted by the Duke Energy Registrants as of September 30, 2025.

Improvements to Income Tax Disclosures . In December 2023, the Financial Accounting Standards Board (FASB) issued new accounting guidance to enhance income tax disclosures by requiring consistent categorization and additional disaggregation of information in the rate reconciliation, as well as an annual disclosure of income taxes paid information disaggregated by jurisdiction. The Duke Energy Registrants plan to adopt this guidance on a prospective basis as of January 1, 2025, in the Company's 2025 Form 10-K. Duke Energy expects this guidance to impact the financial statement disclosures with no impact on the results of operations, cash flows or financial condition.

Disaggregation of Income Statement Expenses. In November 2024, the FASB issued new accounting guidance that requires disclosure of disaggregated information for certain cost and expense categories. This new guidance does not change the expense captions presented on the Condensed Consolidated Statements of Operations but requires disaggregation of certain expense captions into specified categories in disclosures within the notes to the financial statements. For Duke Energy Registrants, the amendments will be effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. Duke Energy is currently assessing implementation of this guidance on the financial statement disclosures and expects it will have no impact on the results of operations, cash flows or financial condition.


FINANCIAL STATEMENTS			DISPOSITIONS

2. DISPOSITIONS

Minority Interest in Florida Progress

On August 4, 2025, Duke Energy, Progress Energy and Florida Progress LLC (Florida Progress), the holding company of Duke Energy Florida, entered into an investment agreement with an affiliate of Brookfield Super-Core Infrastructure Partners (Investor), pursuant to which Florida Progress agreed to issue membership interests to Investor for up to a 19.7 % membership interest in Florida Progress following a series of closings, for an aggregate investment of $ 6 billion, subject to certain adjustments. At the first closing, Florida Progress will issue to Investor 9.2 % of the Florida Progress membership interests for $ 2.8 billion. The first closing will be followed by additional closings with investments occurring no later than on the following timeline: (i) Investor will invest an additional $ 200 million in Florida Progress no later than December 31, 2026; (ii) Investor will invest an additional $ 500 million in Florida Progress no later than June 30, 2027; (iii) Investor will invest an additional $ 1.5 billion in Florida Progress no later than December 31, 2027; and (iv) Investor will invest an additional $ 1 billion in Florida Progress no later than June 30, 2028. The ownership interest of Florida Progress will transfer proportionally with each closing. The Investor has the option to fund its total $ 6 billion investment sooner. The transaction is subject to the satisfaction of certain customary conditions described in the investment agreement, including receipt of the approval of the FERC and completion of review by CFIUS, as well as approval, or a determination that the transaction does not require approval, by the NRC. The investment agreement also provides that, upon termination of the investment agreement under certain specified circumstances prior to the first closing, the Investor would be required to pay Progress Energy a termination fee of $ 240 million.

Proceeds from the minority interest investment are expected to be used to efficiently fund Duke Energy’s growing capital and investment expenditures plan, primarily by displacing certain previously planned issuances of long-term debt and common equity through 2029.

The investment agreement limits Florida Progress’ ability to declare dividends before the first closing (anticipated to be in early 2026). The Investor will receive certain limited rights commensurate wit h its 19.7 % i nvestment in Florida Progress. Duke Energy and Progress Energy will retain control of Florida Progress, so no gain or loss is expected to be recognized on the Condensed Consolidated Statements of Operations. The investment will be presented as noncontrolling interest within stockholders' equity.

Sale of Piedmont's Tennessee Business

On July 27, 2025, Piedmont entered into a purchase agreement with Spire Inc., a Missouri corporation, for the sale of Piedmont's Tennessee business with expected proceeds of $ 2.48 billion, subject to closing adjustments, with proceeds due at closing. Piedmont’s Tennessee business is included within the GU&I segment of Duke Energy and Piedmont. Piedmont expects to complete the sale on March 31, 2026. Completion of the transaction is subject to customary closing conditions, including approval from the TPUC and expiration or termination of the applicable waiting period under the HSR. The HSR waiting period for the transaction expired in September 2025. The purchase agreement contains certain termination rights and provides that Spire Inc. may be required to pay a termination fee for an amount equal to 6.5 % of the purchase price to Piedmont upon termination of the purchase agreement under certain circumstances. In the third quarter of 2025, Duke Energy and Piedmont reclassified the Piedmont Tennessee Disposal Group to assets held for sale. Proceeds from the sale are expected to be used for debt reduction at Piedmont and to efficiently fund Duke Energy's capital plan, primarily by displacing the issuance of common equity in the near term.

Sale of Commercial Renewables Segment

In 2023, Duke Energy completed the sale of substantially all the assets in the Commercial Renewables business segment. Duke Energy closed on the transaction with Brookfield on October 25, 2023, for proceeds of $ 1.1 billion, with approximately half of the proceeds received at closing and the remainder due 18 months after closing. The balance of the remaining proceeds of $ 551 million is included in Receivable from sales of Commercial Renewables Disposal Groups as of December 31, 2024, on Duke Energy's Condensed Consolidated Balance Sheets. O n April 28, 2025, Duke Energy received the remaining sale proceeds from Brookfield. In January 2025, a sale of the remaining Commercial Renewables business assets was completed and proceeds from that disposition were not 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. No interest from corporate level debt was allocated to discontinued operations.

The Piedmont Tennessee Disposal Group was classified as held for sale in the third quarter of 2025. Piedmont ceased recording depreciation and amortization on long-lived assets of the Piedmont Tennessee Disposal Group upon meeting the held for sale criteria in August 2025.

Other Sale-Related Matters

As part of the 2023 purchase and sale agreement for the Commercial Renewables distributed generation group, Duke Energy agreed to retain certain guarantees, with expiration dates between 2029 through 2034, related to tax equity partners' assets and operations that were 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.

3. BUSINESS SEGMENTS

Duke Energy

Duke Energy's segment structure includes the following two segments: EU&I and GU&I.

The EU&I segment primarily includes Duke Energy's regulated electric utilities in the Carolinas, Florida and the Midwest. EU&I also includes the offshore wind contract for Carolina Long Bay.

The GU&I segment includes Piedmont, Duke Energy's natural gas local distribution companies in Ohio and Kentucky and Duke Energy's natural gas storage, midstream pipeline and renewable natural gas investments.

Duke Energy Carolinas and Duke Energy Progress

Hurricanes Debby and Helene

In 2024, hurricanes Debby and Helene significantly impacted the Duke Energy Carolinas and Duke Energy Progress territories in North Carolina and South Carolina. As of September 30, 2025, the total cumulative operations and maintenance expense incurred for restoration and rebuilding of infrastructure associated with the hurricanes was approximately $ 789 million ($ 500 million and $ 289 million for Duke Energy Carolinas and Duke Energy Progress, respectively). The reduction in cumulative operations and maintenance expense compared to December 31, 2024, of $ 112 million for Duke Energy Carolinas and an increase of $ 41 million for Duke Energy Progress, was recorded in Regulatory assets within Other Noncurrent Assets on the Condensed Consolidated Balance Sheets. In addition, through September 30, 2025, there have been cumulative capital investments of $ 494 million ($ 400 million and $ 94 million for Duke Energy Carolinas and Duke Energy Progress, respectively) associated with the hurricanes. Amounts are net of expected insurance recoveries and could change going forward as storm restoration and rebuild work is finalized. Additional estimated capital costs of approximately $ 40 million are expected to be incurred through 2026 to rebuild the systems from hurricane damage.

North Carolina Storm Cost Securitization

In December 2024, Duke Energy Carolinas and Duke Energy Progress filed their joint petition for review and approval of storm recovery costs (Phase 1) with the NCUC to securitize the North Carolina-retail allocable share of storm costs associated with hurricanes Helene, Debby and Ian, as well as Hurricane Zeta and Winter Storm Izzy, and the establishment of storm reserves for $ 200 million at Duke Energy Carolinas and $ 100 million at Duke Energy Progress. On February 3, 2025, Duke Energy Carolinas and Duke Energy Progress filed their joint petition for financing orders (Phase 2). In February 2025, Duke Energy Carolinas and Duke Energy Progress reached a settlement agreement with the North Carolina Public Staff and other intervening parties that resolved all issues between the parties in the Phase 1 proceeding and removed the establishment of storm reserves from the securitization proceeding. Further, the settlement outlined agreement on certain issues in the Phase 2 proce eding. On April 16, 2025, the NCUC issued its Phase 1 order approving the settlement and determining storm recovery costs were reasonable, prudent and eligible for securitization. The order authorized the companies to proceed to Phase 2 of the securitization process. On April 15, 2025, Duke Energy Carolinas and Duke Energy Progress filed a settlement with the North Carolina Public Staff resolving all remaining issues in Phase 2. On June 18, 2025, the NCUC issued its Phase 2 order approving the settlement and issuing the financing orders.


FINANCIAL STATEMENTS			REGULATORY MATTERS

In September 2025, Duke Energy Carolinas and Duke Energy Prog ress issued $ 582 million and $ 461 million, respectively, of storm recovery bonds. Additionally, per the financing orders, any discrepancies between estimates and actual costs of the storms must be accumulated and tracked to allow for a detailed review of the costs for reasonableness and prudency in Duke Energy Carolinas' and Duke Energy Progress’ next general rate case proceedings. As of September 30, 2025, actual North Carolina-retail allocable storm costs were lower than estimates and Duke Energy Carolinas and Duke Energy Progress recorded $ 144 million and $ 77 million, respectively, in Regulatory Liabilities within Other Noncurrent Liabilities on the Condensed Consolidated Balance Sheets. S torm recovery charges were effective November 1, 2025. See Notes 6 and 13 for more information.

South Carolina Storm Cost Securitization

On March 21, 2025, Duke Energy Carolinas filed a petition for storm securitization with the PSCSC for authorization to finance the estimated South Carolina-retail allocable share of storm costs primarily related to Hurricane Helene storm recovery activities and inclusive of funding $ 25 million related to storm reserves . On June 25, 2025, an evidentiary hearing was held. Duke Energy Carolinas reached a comprehensive settlement among all parties in the proceeding, which was filed with the PSCSC supporting securitization of approximately $ 556 million, including the storm reserve funding. On July 10, 2025, the PSCSC approved the settlement and the financing orde r was issued on August 1, 2025. Duke Energy Carolinas expects to securitize the South Carolina-retail allocable share of storm costs by the end of 2025. Due to the relatively low level of storm costs incurred by Duke Energy Progress in South Carolina, Duke Energy Progress will not seek to pursue securitization of those costs and has offset them against established storm reserve balances.

Applications to Combine Utilities

On August 14, 2025, Duke Energy Carolinas and Duke Energy Progress (together, the Companies) filed a joint application with the NCUC and PSCSC for approval to combine utilities, by which Duke Energy Progress will merge into Duke Energy Carolinas, resulting in a single electric utility serving the Companies' North Carolina and S outh Carolina service territories. Duke Energy Corporation, together with the Companies, also filed an application with the FERC on the same day. The single utility’s ability to plan, execute, and operate resources more efficiently is expected to result in substantial cost savings, benefiting customers by reducing the overall costs to serve. Subject to regulatory approvals, the targeted effective date is January 1, 2027. There is no assurance that Duke Energy, Duke Energy Carolinas and Duke Energy Progress will obtain required regulatory approvals from the NCUC, PSCSC and the FERC, and all three approvals are required for the transaction to proceed.

The comment deadline in the FERC proceeding closed on September 4, 2025. Three intervenors offered support for the combination and one filed a protest regarding the mitigation plan for the Companies' Open Access Transmission Tariff rates. Duke Energy responded to the protest on September 19, 2025. A FERC decision is anticipated in the first quarter of 2026.

Evidentiary hearings are scheduled to commence on February 23, 2026, at the NCUC and April 8, 2026, at the PSCSC. Orders are anticipated to be issued in the second quarter of 2026.

2023 North Carolina Rate Case

In January 2023, Duke Energy Carolinas filed a performance-based regulation (PBR) application with the NCUC to request an increase in base rate retail revenues. The PBR application included an MYRP to recover projected capital investments during the three-year MYRP period. In addition to the MYRP, the PBR application included an Earnings Sharing Mechanism, Residential Decoupling Mechanism and Performance Incentive Mechanisms (PIMS) as required by HB951.

In August 2023, Duke Energy Carolinas filed with the NCUC a partial settlement with the North Carolina Public Staff in connection with its PBR application. The partial settlement included, among other things, a greement on a substantial portion of the North Carolina retail rate base for the historic base case of approximately $ 19.5 billion and all of the capital projects and related costs to be included in the three-year MYRP, including $ 4.6 billion (North Carolina retail allocation) projected to go in service over the MYRP period. Additionally, the partial settlement included agreement, with certain adjustments, on depreciation rates, the recovery of grid improvement plan costs and PIMs, Tracking Metrics and the Residential Decoupling Mechanism under t he PBR application. On August 28, 2023, Duke Energy Carolinas filed with the NCUC a second partial settlement with the North Carolina Public Staff resolving additional issues, including the future treatment of nuclear PTCs related to the IRA, through a stand-alone rider that would provide the benefits to customers. This stand-alone rider was effective in rates beginning January 1, 2025.

On December 1 5, 2023, the NCUC issued an order approving Duke Energy Carolinas' PBR application, as modified by the partial settlements and the order, including an overall retail revenue increase of $ 436 million in Year 1, $ 174 million in Year 2 and $ 158 million in Year 3, for a combined total of $ 768 million. T he order established an ROE of 10.1 % based upon an equity ratio of 53 % and approved, with certain adjustments, depreciation rates and the recovery of grid improvement plan costs and certain deferred COV ID-related costs. Additionally, the Residential Decoupling Mechanism and PIMs were approved as requested under the PBR application and revised by the partial settlements. Duke Energy Carolinas implemented interim rates on September 1, 2023. New revised Year 1 rates and the residential decoupling were implemented on January 15, 2024.

Duke Energy Florida

Clean Energy Connection

In July 2020, Duke Energy Florida petitioned the FPSC for approval of a voluntary solar program consisting of 10 new solar generating facilities with combined capacity of 749 MW. The FPSC approved the program in January 2021, allowing participants to support cost-effective solar development in Florida by paying a subscription fee based on per kilowatt subscriptions and receiving a credit on their bill based on the actual generation associated with their portion of the solar portfolio. The 10 new solar generation facilities were completed and all of the remaining sites were in service by the end of 2024 at a cost of approximately $ 1.1 billion. These investments are included in base rates offset by the revenue from the subscription fees, with credits included in the fuel cost recovery clause.

In February 2021, the League of United Latin American Citizens (LULAC) filed a notice of appeal of the FPSC’s order approving the Clean Energy Connection to the Supreme Court of Florida. The Supreme Court of Florida heard oral arguments in the appeal in February 2022. On May 27, 2022, the Supreme Court of Florida issued an order remanding the case back to the FPSC so that the FPSC can amend its order to better address some of the arguments raised by LULAC. In September 2022, the FPSC issued a revised order and submitted it to the Supreme Court of Florida. The Supreme Court of Florida requested that the parties file supplemental briefs regarding the revised order, which were filed in February 2023. On July 17, 2025, the Supreme Court of Florida issued an order affirming the revised FPSC order. The ruling did not change the solar program or have other financial implications. This matter is now fully resolved.

Storm Protection Plan

At least every three years, Duke Energy Florida must file an SPP with the FPSC. Each plan covers a 10-year period and includes investments in transmission and distribution meant to strengthen infrastructure, reduce outage times associated with extreme weather events, reduce restoration costs and improve ove rall service reliability. In April 2022, Duke Energy Florida filed an SPP for approval with the FPSC for the 2023-2032 time frame. The plan reflected approximately $ 7 billion of capital investment in transmission and distribution. The evidentiary hearing began in August 2022. In October 2022, the FPSC approved Duke Energy Florida’s plan with one modification to remove the transmission loop radially fed program, representing a reduction of approximately $ 80 million over the 10-year period starting in 2025. In December 2022, the Office of Public Counsel (OPC) filed a notice of appeal of this order to the Supreme Court of Florida and briefs were filed by the OPC and Duke Energy Florida during 2023. On November 14, 2024, the Supreme Court of Florida issued an order upholding the FPSC's approval of Duke Energy Florida's plan.

In January 2025, Duke Energy Florida filed an SPP for approval with the FPSC for the 2026-2035 time frame reflecting approximately $ 7 billion of capital investment in transmission and distribution. On March 12, 2025, the OPC filed testimony recommending that the pace of the proposed spend be reduced, as well as challenging three subprograms in Duke Energy Florida's SPP. Duke Energy Florida filed rebuttal testimony on April 2, 2025, requesting that the FPSC approve its SPP as filed. On May 16, 2025, Duke Energy Florida and the OPC filed Joint Stipulations to resolve all matters, and the FPSC issued an order on June 19, 2025, approving those stipulations. The stipulations require Duke Energy Florida to defer certain work in two programs from 2026 to 2027 and later. The remainder of Duke Energy Florida's filed SPP was approved without modification. This matter is now fully resolved.

Hurricanes Debby, Helene and Milton

In 2024, Hurricane Debby (Category 1 storm), Hurricane Helene (Category 4 storm) and Hurricane Milton (Category 3 storm) made landfall in Florida and caused significant damage. Duke Energy Florida has certain existing storm reserve regulatory liability amounts, which are applied to the recovery of storm costs. The storm reserve amount was approximately $ 63 million as of July 31, 2024, prior to the damage resulting from hurricanes Debby, Helene and Milton. Duke Energy Florida is permitted to petition the FPSC for recovery of incremental operation and maintenance costs resulting from the storms and to replenish the retail customer storm reserve to approximately $ 132 million.


FINANCIAL STATEMENTS			REGULATORY MATTERS

In December 2024, Duke Energy Florida filed its petition to recover the estimated costs incurred to respond to all three storms, including replenishment of the storm reserve, see king recovery of approximately $ 1.1 billion over 12 months beginning with the first billing cycle in March 2025. Approxim ately $ 103 million and $ 936 million of the operation and maintenance expenses, net of storm reserves, are deferred in Regulatory assets within Current assets as of September 30, 2025, and December 31, 2024, respectively. Approximately $ 85 million of capital related to these storms will be sought for recovery in future base rate case filings. On February 4, 2025, the FPSC voted to approve Duke Energy Florida's request for recovery of these estimated storm costs as filed, subject to true-up after the actual costs are filed. New rates were effective March 1, 2025.

Duke Energy Ohio

Duke Energy Ohio Natural Gas Base Rate Case

In June 2022, Duke Energy Ohio filed a natural gas base rate case application with the PU CO. The drivers for this case were capital invested since Duke Energy Ohio's last natural gas base rate case in 2012. Duke Energy Ohio also sought to adjust the caps on its Capital Expenditure Program (CEP) rider . In April 2023, Duke Energy Ohio filed a stipulation with all parties to the case except the Ohio Consumers' Counsel (OCC). In the stipulation, the parties agreed to approximately $ 32 million in revenue increases with an equity ratio of 52.32 % and an ROE of 9.6 %, and adjustments to the CEP Rider caps. The stipulation was opposed by the OCC at an evidentiary hearing that concluded in May 2023. On November 1, 2023, PUCO issued an order approving the stipulation as filed and new rates went into effect November 1, 2023. In December 2023, the OCC filed an application for rehearing and the PUCO granted OCC's application for rehearing for further consideration of issues raised. As a result of a Supreme Court of Ohio decision regarding procedural issues related to applications for rehearing, PUCO denied OCC’s rehearing request. In October 2024, the OCC filed its Notice of Appeal with the Supreme Court of Ohio. The case is fully briefed and oral argument occurred October 7, 2025. The matter is now submitted for decision.

Duke Energy Ohio Electric Security Plan

In April 2024, Duke Energy Ohio filed with the PUCO a request for an Electric Security Plan (ESP). The ESP application proposed a three-year term from June 1, 2025, through May 31, 2028, and included continuation of market-based rates for generation supply through competitive procurement processes and continuation and expansion of existing rider mechanisms. Duke Energy Ohio proposed a new rider mechanism relating to electric distribution infrastructure modernization programs, which may be enabled by and partially funded through federal or state funding opportunities, as well as future battery storage projects and two electric vehicle programs. Additional proposals included new rider mechanisms related to solar for all investments for low-income and disadvantaged communities, low-income senior citizen bill assistance, and energy efficiency (EE) and demand-side management programs.

In November 2024, Duke Energy Ohio filed a stipulation that the majority of the intervenors signed as either signatory or non-opposing parties. The stipulation includes the continuation of market-based customer rates for generation supply through competitive procurement auctions and the continuation of all existing riders. It further establishes new caps for certain riders. Duke Energy Ohio also agreed to withdraw its proposals for an infrastructure modernization rider, battery storage projects and electric vehicle programs. The stipulation includes a residential EE program with provisions for low-income customers. On May 14, 2025, PUCO issued its order, approving the stipulation without modification.

On May 15, 2025, the governor of Ohio signed Ohio Substitute House Bill 15 (HB15) into law to be effective on August 14, 2025. HB15 requires electric distribution utilities to file a base rate case every three years , commencing no later than December 31, 2029, and establishes an opportunity to apply for approval of a three-year rate plan with forward-looking test periods to mitigate regulatory lag. HB15 eliminates ESPs and certain distribution-related riders, but allows ESPs approved as of its effective date to remain in place through the end of their authorized term. HB15 also eliminates Duke Energy Ohio's Legacy Generation Rider upon the effective date of HB15 and prevents the PUCO from future reauthorization of similar arrangements. As a result of HB15, future losses related to Duke Energy Ohio's Inter-Company Power Agreement with OVEC will not be recoverable from retail customers. There is no regulatory asset related to OVEC as of September 30, 2025, and $ 30 million as of December 31, 2024, recorded in Regulatory Assets within Other Noncurrent Assets on the Condensed Consolidated Balance Sheets.

Duke Energy Ohio RTO Adder

On February 24, 2022, the OCC filed a complaint asserting that FERC should reduce the ROE utilized in transmission formulas for Duke Energy Ohio and certain transmission providers by eliminating the 50 basis point adder associated with RTO membership. The OCC contends this is required because Ohio law mandates that transmission owning utilities join an RTO and that the 50 basis point adder is only applicable where RTO membership is voluntary. On December 15, 2022, FERC denied the complaint as it related to Duke Energy Ohio, but granted it for certain other transmission providers. As a result of appeal by certain other transmission providers, the U.S. Court of Appeals for the Sixth Circuit (Sixth Circuit) on January 17, 2025, reversed the prior decision from FERC. In the decision, the Sixth Circuit ruled the 50 basis point adder is available only where RTO membership is voluntary. The decision noted that Ohio law requires Ohio's transmission utilities to be a member of an RTO and therefore it is unlawful for FERC to remove the adder from certain transmission providers but not also remove the adder from Duke Energy Ohio. As a result, the issue was remanded back to FERC to revise their prior decision. As a result of the ruling, Duke Energy Ohio recognized a pretax charge during 2025, the results of which were not material. On March 26, 2025, the Sixth Circuit denied requests for rehearing. On April 16, 2025, the Sixth Circuit agreed to stay the mandate pending further appeal to the U.S. Supreme Court. On July 17, 2025, Duke Energy Ohio filed a respondent brief at the U.S. Supreme Court requesting review of the Sixth Circuit's decision. Various parties have filed briefs opposing or supporting review by the U.S. Supreme Court. The case has been circulated for conference on November 7, 2025.

On October 22, 2025, Duke Energy Kentucky filed a petition for rehearing with the KPSC related to the treatment of terminal net salvage, rate case expense and recovery of costs from PJM. Additionally, on October 22, 2025, one commercial customer filed a petition for rehearing with the KPSC on a rate design issue which does not impact the overall revenue requirement.

Duke Energy Kentucky 2025 Natural Gas Base Rate Case

On June 2, 2025, Duke Energy Kentucky filed a base rate case with the KPSC requesting an annualized increase in natural gas base rates of approximately $ 26 million and an ROE of 10.75 % with an equity ratio of 52.649 %. This is an overall average customer rate increase of approximately 17 %. The request for the rate increase is driven by capital investments to strengthen the natural gas delivery system. On October 20, 2025, Duke Energy Kentucky filed a settlement with the Office of the Kentucky Attorney General, that if approved, would resolve all issues in the case. The settlement includes an increase in natural gas base rates of approximately $ 22 million, an ROE of 9.8 % for base rates ( 9.7 % for riders), an equity ratio of 52.649 %, and approval for cost recovery of Aldyl-A pipe a nd service replacements through an existing rider . An evidentiary hearing occurred on October 28, 2025. New rates are anticipated to go into effect around January 3, 2026.

Duke Energy Indiana

Indiana Coal Ash Recovery

In Duke Energy Indiana’s 2019 rate case, the IURC opened a subdocket for post-2018 coal ash related expenditures. In April 2020, Duke Energy Indiana filed testimony in the coal ash subdocket requesting recovery for post-2018 coal ash basin closure costs associated with closure plans that were approved by the Indiana Department of Environmental Management (IDEM) at that time as well as continued deferral approval and carrying costs on the balance of such coal ash basin closure costs. On November 3, 2021, the IURC issued an order allowing recovery of the post-2018 coal ash basin closure costs, 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.

In 2023, Duke Energy Indiana filed its proposal to remove from rates certain costs incurred prior to the IURC's November 3, 2021 order date. On September 20, 2023, the IURC approved Duke Energy Indiana's proposal to remove the costs from its rates and assessed simple interest on the refunds at a rate of 4.71 %, beginning from when the costs were initially recovered from customers. In the 2024 Indiana Rate Case, Duke Energy Indiana included a request to recover the pre-order costs denied by the Indiana Court of Appeals and certain future coal ash closure costs as part of depreciation costs. The IURC's January 29, 2025 order in the 2024 Indiana Rate Case denied recovery of the pre-order costs previously denied by the Indiana Court of Appeals but approved the recovery of certain future coal ash closure costs as part of depreciation costs.

In 2023, Duke Energy Indiana filed a petition under the amended version of the federal mandate statute for additional post-2018 coal ash closure costs for the remaining basins not included in the Indiana coal ash recovery case from 2020. On May 8, 2024, the IURC issued a CPCN and approved these coal ash related compliance projects as federally mandated compliance projects. In June 2024, the Citizens Action Coalition of Indiana (CAC) filed a notice of appeal of the IURC's order. On August 26, 2025, the Indiana Court of Appeals reversed the decision by the IURC concluding that the IURC incorrectly allowed Duke Energy Indiana to collect those coal ash costs from customers. In October 2025, Duke Energy Indiana and the Indiana Office of Attorney General filed separate petitions requesting the Indiana Supreme Court to review the case.


FINANCIAL STATEMENTS			REGULATORY MATTERS

TDSIC 2.0

In November 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 July 2022, the OUCC filed a notice of appeal to the Indiana Court of Appeals in Duke Energy Indiana’s TDSIC 2.0 proceeding. The Indiana Court of Appeals issued its opinion on March 9, 2023, affirming the IURC’s order in its entirety. The Duke Industrial Group filed a petition to transfer to the Indiana Supreme Court. On December 19, 2024, the Indiana Supreme Court affirmed the Indiana Court of Appeals decision, concluding there was substantial evidence that the IURC's conclusion was reasonable and the TDSIC 2.0 plan met the statutory requirements. On January 21, 2025, the Duke Industrial Group filed a motion for rehearing. On March 4, 2025, the Indiana Supreme Court denied the Duke Industrial Group's petition for rehearing. There can be no further appeals on TDSIC 2.0 and this matter is now fully resolved.

2024 Indiana Rate Case

In April 2024, Duke Energy Indiana filed an application with the IURC for a rate increase for retail customers. T he request for rate increase was driven by $ 1.6 billion in investments made since the last general rate case filed in 2019 in order to reliably serve customers, improve resiliency of the system, and advance environmental sustainability.

An order for the rate case was issued by the IURC on January 29, 2025, and revised February 3, 2025, which authorized an ROE of 9.75 %, an equity ratio of 53 % and an annual revenue increase of $ 296 million. Based on review of these orders, Duke Energy Indiana identified an inconsistency in the calculation of operating revenues before the effect of trackers. On February 7, 2025, Duke Energy Indiana made a compliance filing in accordance with the IURC's findings in its order and addressed the identified inconsistencies. The compliance filing also clarified the annual revenue increase was approximately $ 385 million. On February 18, 2025, one industrial customer submitted a filing requesting the IURC to clarify its revenue allocation in these proceedings, which was denied by the Commission on April 16, 2025. On February 25, 2025, the IURC approved Duke Energy Indiana’s compliance filing and new rates were implemented February 27, 2025. The industrial customer filed a notice of appeal on February 28, 2025, regarding cost of service allocation. On April 9, 2025, the IURC issued an order clarifying the intent of its January 29, 2025 order regarding the rate migration adjustment, resulting in revised rates that were effective on May 19, 2025. On May 14, 2025, the industrial customer filed a motion to dismiss its appeal, and on May 20, 2025, the Indiana Court of Appeals granted the industrial customer's motion to dismiss. This matter is now fully resolved.

Cayuga Combined Cycle CPCN

On February 13, 2025, Duke Energy Indiana filed for a CPCN seeking approval to construct two 1x1 CC natural gas-fired units with a combined winter rating of 1,476 MW. The Cayuga CC Project is proposed to be constructed on the same site as the retiring Cayuga coal-fired steam units with a winter rating of 1,005 MW. The Cayuga CC Project will result in an incremental 471 MW for the Duke Energy Indiana system and will allow Duke Energy Indiana to avoid expected maintenance and environmental compliance costs needed for the coal units to continue operating. The estimated cost of the Cayuga CC project is approximatel y $ 3.3 billion , plus actual AFUDC. Duke Energy Indiana has proposed recovery of certain facility costs during construction, including AFUDC, through CWIP ratemaking via a proposed generation cost tracker mechanism. The estimated average retail rate impact during construction and initial in-service periods from April 2026 through May 2031 is approximately 5.4 %. Duke Energy Indiana expects CC 1 to be placed in service in 2029 and CC 2 to be placed in service in 2030. A final air permit was issued by IDEM on March 5, 2025. On June 17, 2025, Duke Energy Indiana entered into a settlement agreement with one of the parties in this proceeding to conduct a study evaluating the feasibility of third-party operation of the Cayuga coal units. On July 11, 2025, Duke Energy Indiana entered into a settlement agreement with an additional party in this proceeding agreeing to the need of the units and addressing accounting and ratemaking components. Neither agreement altered the underlying plans in the pending CPCN application. On October 29, 2025, the IURC issued its order approving the settlement agreements, granting the CPCN and approving cost recovery through the proposed generation cost tracker mechanism.

ENVIRONMENTAL

Remediation Activities

In addition to Asset Retirement Obligations 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.


FINANCIAL STATEMENTS			COMMITMENTS AND CONTINGENCIES

The following table contains information regarding reserves for probable and estimable costs related to the various environmental sites.

D uke Energy

Mooresville Coal Ash Class Action Litigation

On December 20, 2024, 15 plaintiffs filed a lawsuit in Iredell County, North Carolina, against Duke Energy (Parent), Duke Energy Carolinas and Duke Energy Progress (collectively “Duke Energy”) on behalf of a putative class alleging past and ongoing environmental contamination in the Mooresville area of North Carolina. The lawsuit alleges that Duke Energy disposed of and sold coal ash as structural fill resulting in the contamination of soil, groundwater and Lake Norman. The plaintiffs claim that Duke Energy failed to properly remediate the contamination and continues to pollute, and they assert that the contamination has negatively impacted property values. The plaintiffs are seeking unspecified compensatory and punitive damages, injunctive relief to stop further contamination, remediation of contaminated areas and attorneys' fees and costs. On July 28, 2025, the plaintiffs filed an amended complaint, which asserts claims for negligence, negligence per se, gross negligence, private nuisance, strict liability for ultra-hazardous activities and trespass. On September 11, 2025, Duke Energy filed its answer to the plaintiff's amended complaint and a motion for judgment on the pleadings. A hearing on the motion for judgment on the pleadings is scheduled for December 15, 2025.

Nuclear Compensation Class Action Litigation

On July 11, 2025, plaintiffs Leo Dorrell and John Dunn filed a putative class action lawsuit in the U.S. District Court for the District of Maryland against all U.S. commercial nuclear power operators, including Duke Energy Corporation (Parent) and Progress Energy. The plaintiffs allege that the nuclear power industry engaged in a conspiracy to suppress compensation by exchanging salary information since 2003, in violation of Section 1 of the Sherman Act. The lawsuit seeks unspecified monetary damages, including treble damages, on behalf of current and former employees in the nuclear power industry as well as injunctive relief. On October 15, 2025, all defendants jointly filed an omnibus motion to dismiss all claims in the complaint and Duke Energy also joined a motion filed by several defendants to dismiss for lack of personal jurisdict ion. On November 5, 2025, the plaintiffs filed an amended complaint adding Duke Energy Carolinas and Duke Energy Business Services as defendants and including more factual allegations to support their complaint. Although not named as a defendant, Duke Energy Progress is accused of having participated in the alleged conspiracy. The defendants have until November 19, 2025, to respond to the amended complaint.

Duke Energy Carolinas

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. In September 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 an 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. In April 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. In October 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.

In November 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. On August 5, 2024, the U.S. Court of Appeals for the Fourth Circuit reversed the district court's grant of summary judgment and remanded the case back to the district court for further proceedings. In August 2024, Duke Energy Carolinas filed a petition for rehe aring, which was denied on November 26, 2024. On February 21, 2025, Duke Energy Carolinas filed a petition seeking review by the U.S. Supreme Court. On June 2, 2025, the U.S. Supreme Court invited the Solicitor General to file a brief reflecting the views of the U.S. as it relates to this matter.

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 Caroli nas has recognized asbestos-related reserves of $ 404 million at September 30, 2025, and $ 396 million at December 31, 2024. 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 2045 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 2045 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 $ 557 million at September 30, 2025, a nd $ 539 million at December 31, 2024. 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 $ 9 million as of September 30, 2025, and December 31, 2024, for both Duke Energy and Duke Energy 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.

Duke Energy Indiana

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). In June 2024, Duke Energy Indiana filed an amended complaint adding several additional insurance companies as defendants to the litigation. During 2023 through 2025, Duke Energy In diana reached confidential settlements with various insurance companies, the results of which were not material to Duke Energy. All settlement payments have been received and the case has been dismissed. In July 2025, Duke Energy Indiana began refunding retail customers their share of coal ash insurance settlement proceeds, after expenses, over one year .

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, non-cancelable 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.

8. GOODWILL

Duke Energy

Duke Energy's Goodwill balance of $ 19.0 billion is allocated $ 17.4 billion to EU&I and $ 1.6 billion to GU&I on Duke Energy's Condensed Consolidated Balance Sheets at September 30, 2025, and December 31, 2024. There are no accumulated impairment charges.

On July 27, 2025, Piedmont entered into a purchase agreement for the sale of Piedmont's Tennessee business. In the third quarter of 2025, Duke Energy reclassified the Piedmont Tennessee Disposal Group to assets held for sale. As a result, $ 294 million of Duke Energy’s Goodwill balance that is allocated to the Piedmont Tennessee Disposal Group was reclassified to noncurrent assets held for sale on Duke Energy's Condensed Consolidated Balance Sheets. See Note 2 for additional information.

Duke Energy Ohio

Duke Energy Ohio's Goodwill balance of $ 920 million, allocated $ 596 million to EU&I and $ 324 million to GU&I, is presented net of accumulated impairment charges of $ 216 million on the Condensed Consolidated Balance Sheets at September 30, 2025, and December 31, 2024.

Progress Energy

Progress Energy's Goodwill is included in the EU&I segment and there are no accumulated impairment charges.

Piedmont

Piedmont's Goodwill is included in the GU&I segment and there are no accumulated impairment charges.

On July 27, 2025, Piedmont entered into a purchase agreement for the sale of Piedmont's Tennessee business. In the third quarter of 2025, $ 10 million of Piedmont’s Goodwill balance that is allocated to the Piedmont Tennessee Disposal Group was reclassified to noncurrent assets held for sale on Piedmont's Condensed Consolidated Balance Sheets. See Note 2 for additional information.

Impairment Testing

Duke Energy, Progress Energy, Duke Energy Ohio and Piedmont are required to perform an annual goodwill impairment test as of the same date each year and, accordingly, perform their annual impairment testing of goodwill as of August 31. Duke Energy, Progress Energy, Duke Energy Ohio and Piedmont update their test between annual tests if events or circumstances occur that would more likely than not reduce the fair value of a reporting unit below its carrying value. As the fair value for Duke Energy, Progress Energy, Duke Energy Ohio and Piedmont exceeded their respective carrying values at the date of the annual impairment analysis, no goodwill impairment charges were recorded in the third quarter of 2025.

10. 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.

All derivative instruments not identified as NPNS are recorded at fair value as assets or liabilities o n the Condensed Consolidated Balance Sheets. Cash collateral related to derivative instruments ex ecuted 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 on the Condensed Consolidated Statements of Cash Flows.

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.

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 and nine months ended September 30, 2025, and 2024, 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

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.

Fair Value Hedges

Derivatives related to existing 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.

OBJECTIVE CREDIT CONTINGENT FEATURES

Certain derivative contracts contain objective credit contingent features. These features include the requirement to post cash collateral or letters of credit if specific events occur, such as a credit rating downgrade below investment grade. The following tables show information with respect to derivative contracts that are in a net liability position and contain objective credit risk-related payment provisions.

The Duke Energy Registrants have elected to offset cash collateral and fair values of derivatives. For amounts to be netted, the derivative and cash collateral must be executed with the same counterparty under the same master netting arrangement.

11. INVESTMENTS IN DEBT AND EQUITY SECURITIES

Duke Energy’s investments in debt and equity securities are primarily comprised of investments held in (i) the nuclear decommissioning trust funds (NDTF) at Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida, (ii) the grantor trusts at 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 September 30, 2025, and December 31, 2024.

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

12. 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 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 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 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.

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, 2024, for a discussion of the valuation of goodwill and intangible assets.

13. VARIABLE INTEREST ENTITIES

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 nine months ended September 30, 2025, and the year ended December 31, 2024, or is expected to be provided in the future that was not previously contractually required.

Receivables Financing – DERF/DEPR/DEFR

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

DERF, DEPR and DEFR borrowed amounts under credit facilities to buy these receivables. Borrowing availability from the credit facilities was limited to the amount of qualified receivables purchased, which generally excluded 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 were cash collections from the receivables. Amounts borrowed under the DERF and DEPR credit facilities were reflected on the Condensed Consolidated Balance Sheets as Current maturities of long-term debt as of December 31, 2024.

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

In January 2025, Duke Energy Carolinas repaid all outstanding DERF borrowings totaling $ 500 million and terminated the related DERF credit facility. Additionally, Duke Energy Carolinas' related restricted receivables outstanding at DERF at the time of termination totaled $ 1,081 million and were transferred back to Duke Energy Carolinas to be collected and reported as Receivables on the Condensed Consolidated Balance Sheets.

In March 2025, Duke Energy Progress repaid all outstanding DEPR borrowings totaling $ 400 million and terminated the related DEPR credit facility. Additionally, Duke Energy Progress' related restricted receivables outstanding at DEPR at the time of termination totaled $ 943 million and were transferred back to Duke Energy Progress to be collected and reported as Receivables on the Condensed Consolidated Balance Sheets.

Receivables Financing – CRC

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.

Nuclear Asset-Recovery Bonds

Duke Energy Florida Project Finance, LLC (DEFPF) is a bankruptcy remote, wholly owned special purpose subsidiary of Duke Energy Florida. DEFPF was formed in 2016 for the sole purpose of issuing nuclear asset-recovery bonds to finance Duke Energy Florida's unrecovered regulatory asset related to Crystal River Unit 3.

In 2016, DEFPF issued senior secured bonds and used the proceeds to acquire nuclear asset-recovery property from Duke Energy Florida. The nuclear asset-recovery property acquired includes the right to impose, bill, collect and adjust a non-bypassable nuclear asset-recovery charge from all Duke Energy Florida retail customers until the bonds are paid in full and all financing costs have been recovered. The nuclear asset-recovery bonds are secured by the nuclear asset-recovery property and cash collections from the nuclear asset-recovery charges are the sole source of funds to satisfy the debt obligation. The bondholders have no recourse to Duke Energy Florida.

DEFPF is considered a VIE primarily because the equity capitalization is insufficient to support its operations. Duke Energy Florida has the power to direct the significant activities of the VIE as described above and therefore Duke Energy Florida is considered the primary beneficiary and consolidates DEFPF.

The following table summarizes the impact of DEFPF on Duke Energy Florida's Condensed Consolidated Balance Sheets.

Storm Recovery Bonds

Duke Energy Carolinas NC Storm Funding, LLC (DECNCSF), Duke Energy Carolinas NC Storm Funding II, LLC (DECNCSFII), Duke Energy Progress NC Storm Funding, LLC (DEPNCSF), Duke Energy Progress NC Storm Funding II, LLC (DEPNCSFII) and Duke Energy Progress SC Storm Funding, LLC (DEPSCSF) are bankruptcy remote, wholly owned special purpose subsidiaries of Duke Energy Carolinas and Duke Energy Progress. DECNCSF and DEPNCSF were formed in 2021, DEPSCSF was formed in 2024, and DECNCSFII and DEPNCSFII were formed in 2025, all for the sole purpose of issuing storm recovery bonds to finance certain of Duke Energy Carolinas’ and Duke Energy Progress’ unrecovered regulatory assets related to storm costs incurred in North Carolina and South Carolina.

In 2021, DECNCSF and DEPNCSF issued senior secured bonds, and used the proceeds to acquire storm recovery property from Duke Energy Carolinas and Duke Energy Progress. The storm recovery property was created by state legislation and NCUC financing orders for the purpose of financing storm costs incurred in 2018 and 2019. In April 2024, DEPSCSF issued $ 177 million of senior secured bonds and used the proceeds to acquire storm recovery property from Duke Energy Progress. The storm recovery property was created by state legislation and a PSCSC financing order for the purpose of financing storm costs incurred from 2014 through 2022. In September 2025, DECNCSFII issued $ 582 million of senior secured bonds and used the proceeds to repay Duke Energy Carolinas' term loan facility. Also in September 2025, DEPNCSFII issued $ 461 million of senior secured bonds and used the proceeds to repay Duke Energy Progress' term loan facility. See Note 6 for more information.

Procurement Company – Duke Energy Florida

Duke Energy Florida Purchasing Company, LLC (DEF ProCo) is a wholly owned special purpose subsidiary of Duke Energy Florida. DEF ProCo was formed in 2023 as the primary procurement agent for equipment, materials and supplies for Duke Energy Florida. DEF ProCo interacts with third-party suppliers on Duke Energy Florida’s behalf with credit and risk support provided by Duke Energy Florida. DEF ProCo is a qualified reseller under Florida tax law and conveys acquired assets to Duke Energy Florida through leases on each acquired asset.

This entity is considered a VIE primarily because the equity capitalization is insufficient to support their operations. Duke Energy Florida has the power to direct the significant activities of this VIE as described above and therefore Duke Energy Florida is considered the primary beneficiary and consolidates the procurement company.

The following table summarizes the impact of this VIE on Duke Energy Florida's Consolidated Balance Sheets.

Accounts Payable	266		208

NON-CONSOLIDATED VIEs

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.

Non-consolidated VIEs are immaterial on the Condensed Consolidated Balance Sheets and the Duke Energy Registrants are not aware of any situations where the maximum exposure to loss significantly exceeds the carrying values.

14. 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 as of September 30, 2025:


	Remaining Performance Obligations

Duke Energy Florida	7		37		7		7		7		22		87

Duke Energy Indiana	4		17		15		6		—		—		42

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 as of September 30, 2025, 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.

15. 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.

(a) The convertible notes were excluded from the calculation of diluted EPS for the three months ended September 30, 2024, and the nine months ended September 30, 2025 and 2024, because the effect was antidilutive. For the three months ended September 30, 2025, the convertible notes were included in the calculation of diluted EPS, but the impact was immaterial.

(b) Performance stock awards were not included in the dilutive securities calculation because the performance measures related to the awards had not been met.

(c) 5.75 % Series A Cumulative Redeemable Perpetual Preferred Stock dividends are payable quarterly in arrears on the 16th day of March, June, September and December. The preferred stock has a $ 25 liquidation preference per depositary share.

(d) 4.875 % Series B Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Stock dividends were payable semiannually in arrears on the 16th day of March and September. The preferred stock was redeemed on September 16, 2024.

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 was entitled to issue and sell shares of common stock through September 2025.

The following table shows ATM equity issuances pursuant to forward contracts executed during February and March 2025.



Tranche	Shares Priced	Initial Forward Price
1	1,710,979	$	116.02
2	1,262,618	$	117.94
3	1,264,410	$	117.79

Total	4,238,007

The equity forwards require Duke Energy to either physically settle the transactions 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 alternatives are 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 forwards occurs, which is expected by December 31, 2026. The initial forward sale prices 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 agreements. Until settlement of the equity forwards, earnings per share dilution resulting from the agreements, if any, will be determined under the treasury stock method.


FINANCIAL STATEMENTS			STOCKHOLDERS' EQUITY

Preferred Stock

On September 16, 2024, Duke Energy redeemed all 1 million outstanding shares of Series B Preferred Stock for a redemption price of $ 1,000 per share or $ 1 billion in total. Following the redemption, dividends ceased to accrue on the shares of Series B Preferred Stock, shares of the Series B Preferred Stock were no longer deemed outstanding and all rights of the holders of such shares of Series B Preferred Stock terminated. In conjunction with the redemption, Duke Energy recorded $ 16 million in preferred stock redemption costs, calculated as the difference of $ 11 million between the carrying value on the redemption date of the Series B Preferred Stock and the total amount of consideration paid to redeem, and including the recognition of an excise tax liability under the IRA of $ 5 million. The preferred stock redemption costs were recorded as a reduction to Retained earnings on Duke Energy Corporations' Condensed Consolidated Balance Sheets during the three and nine months ended September 30, 2024.

Net periodic costs for OPEB plans were not material for the three and nine months ended September 30, 2025, and 2024.

17. INCOME TAXES

The IRA established transferability markets for tax credits including nuclear PTCs, solar PTCs and I TCs. In April 2025, agreements were executed for the sale of approximately $ 643 million in net tax credits under the IRA. The sale primarily includes estimated nuclear PTCs of $ 478 million at Duke Energy Carolinas and $ 69 million at Duke Energy Progress, as well as estimated solar PTCs of $ 58 million at Duke Energy Florida to be earned through the end of 2025. Proceeds for the sale of the nuclear PTCs are expected to be received in November 2025. Receivables related to Duke Energy Carolinas' nuclear PTC sales were $ 382 million as of September 30, 2025, and are classified in Other within Current Assets on the Condensed Consolidated Balance Sheets.

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law, which among other things, modified tax legislation affecting clean energy tax credits. While transferability was preserved for tax credits established by the IRA, including the nuclear PTC, which remains available through 2032, the legislation phases out or terminates certain tax credits sooner than previously scheduled. To remain eligible for the PTC or ITC, solar and wind facilities must be placed in service by December 31, 2027, unless construction begins by July 4, 2026. For other types of facilities, the credits continue to be available at full value if construction begins by December 31, 2033, although there are new prohibited foreign entity restrictions. The OBBBA did not change the federal corporate income tax rate and did not require the remeasurement of deferred tax assets or liabilities. While Duke Energy does not expect material current year impacts to the results of operations, financial position or cash flows for the Duke Energy Registrants as a result of the OBBBA being signed into law in the third quarter of 2025, the Company will continue to evaluate the future impact of this tax law change as additional 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, an energy company headquartered in Charlotte, North Carolina, 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. Duke Energy’s consolidated financial information 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 nine months ended September 30, 2025, and with Duke Energy’s Annual Report on Form 10-K for the year ended December 31, 2024.

Executive Overview

Acting on Investment Opportunities. We operate in some of the most attractive jurisdictions in the country and the affordable, reliable power we provide continues to play a key role in bringing business and job growth to our region. Our service territories continue to experience accelerating investment opportunities driven by a deepening economic development pipeline and significant customer growth. To efficiently fund this growth and the related capital required in the coming years, we entered into two strategic transactions in the third quarter of 2025.

In August 2025, we entered into an investment agreement to receive $6 billion in exchange for a 19.7% indirect investment in Duke Energy Florida. Subject to regulatory approvals, the transaction is expected to be completed through a series of closings starting in 2026 through mid-2028. In July 2025, we announced the sale of Piedmont’s Tennessee business to Spire Inc. for $2.48 billion. Subject to regulatory approvals, we expect to complete the Piedmont transaction on March 31, 2026. Proceeds from both transactions will support Duke Energy’s expanded capital plan and replaces certain originally planned long-term debt and common equity issuances through 2029.

Both of these transactions, along with our unwavering focus on operational excellence and value creation, demonstrate our continued ability to meet the unprecedented long-term growth anticipated across our service territories. See Note 2 to the Condensed Consolidated Financial Statements, "Dispositions," for further information.

Building a Smarter Energy Future. During the nine months ended September 30, 2025, we continued to move our regulatory strategy forward and execute on investments for building a smarter energy future while maintaining our focus on safety and operational excellence, our customers, growth of our business as well as the engagement and empowerment of our employees. These priorities enable us to provide strong, sustainable value for our employees, customers, communities and shareholders.

• In January 2025, Piedmont and Duke Energy Indiana received constructive orders on their general rate cases from the NCUC and IURC, respectively. New rates were effective in November 2024 for Piedmont and late February 2025 for Duke Energy Indiana. New rates were also effective in January 2025 for Duke Energy Florida's new three-year rate plan. In June 2025, Duke Energy Progress filed a South Carolina base rate case and Duke Energy Kentucky filed a natural gas base rate case. In July 2025, Duke Energy Carolinas filed a South Carolina base rate case. In October 2025, Duke Energy Kentucky received a constructive order on its electric base rate case filed last December and Duke Energy Progress reached a comprehensive settlement in its South Carolina base rate case. Our regulatory efforts continue to focus on securing critical investments for reliable customer service while ensuring timely cost recovery across our service territories.

• In October 2025, Duke Energy Progress received an order from the NCUC granting the CPCN for the second CC unit in Person County and Duke Energy Indiana received an order from the IURC granting the CPCN for the Cayuga CC project. Also in October 2025, Duke Energy Carolinas filed for a CECPCN with the PSCSC for a new CC unit in Anderson County, South Carolina. These advanced natural gas plants, along with our planned CTs, will provide critical generation as we continue to modernize our energy infrastructure in the coming years.

• We reached key milestones to recover costs related to critical storm restoration activities from the 2024 historic storm season while also seeking to minimize customer bill impacts resulting from hurricanes Debby, Helene and Milton. In February 2025, the FPSC voted to approve Duke Energy Florida's storm cost recovery of approximately $1.1 billion over 12 months beginning in March 2025. During 2025, Duke Energy Carolinas and Duke Energy Progress reached constructive settlements in Phase 2 proceedings and financing orders have been issued by both the NCUC and PSCSC. In Septe mber 2025, we issued North Carolina storm recovery bonds and expect to securitize the related South Carolina storm costs by the end of 2025.

• Our nuclear sites continue to positively impact the customers we serve by safely producing clean, reliable and low-cost electricity, as well as providing economic benefits for our local communities that includes thousands of well-paying jobs and significant tax benefits. During 2025, we continue to sell nuclear PTCs to further reduce the cost of electricity for our customers. Additionally, in March 2025, the NRC issued a subsequent license renewal for Oconee that allows an additional 20 years of operation through 2054. Oconee is the first Duke Energy nuclear facility to reach this significant approval milestone to permit extension of its operations to 80 years. In April 2025, we submitted an application to the NRC for Robinson to extend the plant's operations an additional 20 years through 2050.

• In July 2025, Duke Energy Carolinas filed its final license application with the FERC to extend the operating license for the Bad Creek Pumped Storage Hydroelectric Station. Located in South Carolina, Bad Creek is designed to produce significant amounts of energy when our customers need it most, performing a vital role on the company's system since 1991. If approved, the application would extend plant operations for an additional 50 years through 2077.

MD&A			DUKE ENERGY

• In August 2025, we filed applications with the NCUC, PSCSC and FERC to combine our utilities that operate in the Carolinas, by which Duke Energy Progress will merge into Duke Energy Carolinas. This proposed transaction would result in a single electric utility serving our North Carolina and S outh Carolina service territories. The single utility’s ability to plan, execute and operate resources more efficiently is expected to result in substantial cost savings to benefit customers by reducing the overall costs to serve. The targeted effective date is January 1, 2027, subject to regulatory approvals.

Operational Excellence. In June 2025, as the summer's first heat wave brought triple-digit temperatures to parts of North Carolina and South Carolina, our customers set a new summertime record for electricity usage, surpassing the previous summertime record set in July 2024. We maintain our focus on operational excellence and prepare for extreme weather by identifying potential risks, effectively maintaining adequate short-term planning reserves, leveraging outage scheduling optimization and controlling planned and emergent equipment issues.

Economic Development. In June 2025, the governor of North Carolina announced Amazon is planning to invest an estimated $10 billion to launch a new high-tech cloud computing and artificial intelligence innovation campus in Richmond County, North Carolina. The site selected for this project was included in Duke Energy's Site Readiness Program in 2019, a program that helps state, regional and local economic development partners increase the competitiveness of potential industrial land. These new data centers will be located in Duke Energy Progress' service territory and the investment is expected to be among the largest in North Carolina's history, a testament to the impactful and ongoing work of continuing to bring economic development success to the vibrant communities we proudly serve.

See Notes 4 and 17 to the Condensed Consolidated Financial Statements, "Regulatory Matters" and "Income Taxes," for additional information.

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.

Regulatory Matters

Coal Ash Costs

In April 2024, the EPA issued the 2024 CCR Rule, which significantly expands the scope of the 2015 CCR Rule by establishing regulatory requirements for inactive surface impoundments at retired generating facilities and previously unregulated coal ash sources at regulated facilities. Duke Energy is participating in legal challenges to the 2024 CCR Rule.

Cost recovery for future expenditures is anticipated and will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of reasonable and prudently incurred costs associated with Duke Energy’s regulated operations. For more information, see "Other Matters" and Note 4 to the Condensed Consolidated Financial Statements, "Regulatory Matters."

Storm Cost Recovery

From August through October 2024, a series of major storm events occurred that resulted in significant damage to utility infrastructure within our service territories and primarily impacted Duke Energy Carolinas', Duke Energy Progress' and Duke Energy Florida's electric utility operations. Hurricanes Debby, Helene and Milton caused widespread outages and included unprecedented damage to certain assets, including the hardest-hit areas on the western coast of Florida and certain regions in western North Carolina and upstate South Carolina. Appropriate storm cost recovery mechanisms are in place to track and recover incremental costs from such events. Funding restoration activities and, in some cases, the complete rebuild of critical infrastructure, for a series of sequential events of this magnitude has resulted in incremental financing needs until cost recovery occurs and may impact the near-term results of operations, financial position or cash flows of the impacted registrants. Regulatory filings have been made for recovery of storm costs across all jurisdictions and full recovery is expected by early 2026. For more information related to storm costs, regulatory asset deferrals and financing activities, see "Liquidity and Capital Resources" and Notes 4, 6 and 13 to the Condensed Consolidated Financial Statements, "Regulatory Matters," "Debt and Credit Facilities" and Variable Interest Entities."

EPA Regulations of GHG Emissions

In April 2024, the EPA issued final rules 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. Duke Energy is analyzing the potential impacts the rules could have on the Company, which could be material and may influence the timing, nature and magnitude of future generation investments in our service territories. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of reasonable and prudently incurred costs associated with Duke Energy’s regulated operations. Duke Energy is participating in legal challenges to the final rules. In June 2025, the EPA proposed to repeal EPA Rule 111 as well as an alternative proposal for a narrower set of requirements. For more information, see "Other Matters."

Supply Chain

The Company continues to monitor the ongoing stability of markets for key materials and supplies, including potential restrictions on the trade of certain rare earth materials and technologies used in electric utility infrastructure. Public policy outcomes, including potential impacts from new or escalating tariffs or other actions from federal executive orders, federal legislation or other rulemakings, could disrupt or impact Duke Energy's supply chain, future financial results, capital plan execution or the ability to execute on the Company's vision for a smarter energy future.

Goodwill

The Duke Energy Registrants performed their annual goodwill impairment tests as of August 31, 2025. 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 have been recorded in the accompanying Condensed Consolidated Statements of Operations, the potential for deteriorating economic conditions impacting GU&I's future cash flows or equity valuations of peer companies could impact the estimated fair value of GU&I, and goodwill impairment charges could be recorded in the future.

104


MD&A			MATTERS IMPACTING FUTURE RESULTS

Minority Interest in Florida Progress

In August 2025, Duke Energy, Progress Energy and Florida Progress entered into an investment agreement for Florida Progress to receive $6 billion in exchange for a 19.7% indirect investment in Duke Energy Florida. The transaction is subject to the satisfaction of certain customary conditions described in the investment agreement, including receipt of the approval of the FERC and completion of review by CFIUS, as well as approval, or a determination that the transaction does not require approval, by the NRC. The transaction is expected to be completed through a series of closings through June 30, 2028. Termination of the transaction under certain specified circumstances could require the investor to pay a $240 million termination fee to Progress Energy and result in Duke Energy seeking alternative funding sources through 2029, including additional long-term debt and common equity issuances. For additional information, see Note 2 to the Condensed Consolidated Financial Statements, “Dispositions.”

Sale of Piedmont's Tennessee Business

In July 2025, Piedmont entered into a purchase agreement to sell Piedmont’s Tennessee business. Completion of the transaction is subject to customary closing conditions, including approval from the TPUC and expiration or termination of the applicable waiting period under the HSR. The HSR waiting period for the transaction expired in September 2025. There is no assurance of the transaction as failure to obtain related approvals or to satisfy conditions in the purchase agreement could result in termination of the transaction. The purchase agreement contains termination rights and Spire Inc. may be required to pay a termination fee equal to 6.5% of the purchase price under certain circumstances that result in termination of the transaction. Termination of the purchase agreement could also result in Duke Energy seeking alternative funding sources for its 2025-2029 capital and investment expenditures plan, including additional long-term debt and common equity issuances. Completion of the transaction could impact the operating revenues and profitability of Piedmont, including potential recognition of a gain on sale. In the third quarter of 2025, Duke Energy and Piedmont reclassified the Piedmont Tennessee Disposal Group to assets held for sale. For additional information, see Note 2 to the Condensed Consolidated Financial Statements, “Dispositions.”

Other

Duke Energy continues to monitor general market conditions, including the potential for interest rate pressures on the Company's cost of capital, which may impact Duke Energy's capital plan execution, future financial results or the ability to execute on the Company's vision for a smarter energy future.

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 exclude (or include) 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 basic per share amounts, adjusted for the dollar and per share impact of special items. 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 Basic 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 primarily represents impairment charges related to the 2024 Duke Energy Carolinas' South Carolina rate case order.

• System Post-Implementation Costs represents the net impact of charges related to nonrecurring customer billing adjustments as a

result of implementation of a new customer system.

• Preferred Redemption Costs represents charges related to the redemption of Series B Preferred Stock.

Discontinued operations primarily represents the operating results of Duke Energy's Commercial Renewables Disposal Groups.

Three Months Ended September 30, 2025, as compared to September 30, 2024

GAAP reported EPS was $1.81 for the three months ended September 30, 2025, compared to $1.60 for the three months ended September 30, 2024. In addition to the drivers below, GAAP reported EPS increased primarily due to the net impact of charges related to nonrecurring customer billing adjustments in the prior year and charges related to the redemption of Series B Preferred Stock in the prior year.

As discussed above, management also evaluates financial performance based on adjusted EPS. Duke Energy’s adjusted EPS was $1.81 for the three months ended September 30, 2025, compared to $1.62 for the three months ended September 30, 2024. The increase in adjusted EPS was primarily due to the implementation of new rates and riders, along with higher sales volumes, partially offset by higher interest expense, milder weather, and higher depreciation and property taxes on a growing asset base.

Nine Months Ended September 30, 2025, as compared to September 30, 2024

GAAP Reported EPS was $4.81 for the nine months ended September 30, 2025, compared to $4.17 for the nine months ended September 30, 2024. In addition to the drivers below, GAAP reported EPS increased primarily due to impairments related to the 2024 South Carolina rate case in the prior year, the net impact of charges related to nonrecurring customer billing adjustments in the prior year and charges related to the redemption of Series B Preferred Stock in the prior year.

As discussed above, management also evaluates financial performance based on adjusted EPS. Duke Energy’s adjusted EPS was $4.81 for the nine months ended September 30, 2025, compared to $4.24 for the nine months ended September 30, 2024. The increase in adjusted EPS was primarily due to the implementation of new rates and riders, along with higher retail sales volumes, partially offset by higher interest expense, operation and maintenance expense, and depreciation and property taxes on a growing asset base.

EU&I’s results were driven by higher revenues from rate cases across multiple jurisdictions and higher weather-normal retail sales volumes, partially offset by higher operation and maintenance and depreciation expenses . The following is a detailed discussion of the variance drivers by line item.

Operating Revenues. The variance was driven primarily by:

• a $286 million increase in storm recovery revenues at Duke Energy Florida;

• a $238 million increase due to higher pricing from jurisdictional rate cases primarily at Duke Energy Carolinas, Duke Energy Indiana, Duke Energy Florida and Duke Energy Progress;

• a $94 million increase in weather-normal retail sales volumes; and

• a $22 million increase in other revenues primarily due to higher transmission revenues across all jurisdictions.

Partially offset by:

• a $329 million decrease in fuel revenues primarily due to net lower rates in the current year.

Operating Expenses . The variance was driven primarily by:

• a $341 million increase in operation, maintenance and other primarily driven by higher storm amortization at Duke Energy Florida, increased costs related to customer products and services programs at Duke Energy Carolinas, higher plant maintenance at Duke Energy Indiana and higher employee-related expenses across all jurisdictions , partially offset by lower storm costs in the current year at Duke Energy Progress, Duke Energy Carolinas and Duke Energy Ohio ;

• a $96 million increase in depreciation and amortization primarily due to higher depreciable base across all jurisdictions and higher depreciation rates driven by rate cases; and

• a $49 m illion increase in property and other taxes due to a higher base on which property taxes are levied and higher sales and use tax refunds in the prior year at Duke Energy Carolinas and Duke Energy Progress.

• a $735 million increase due to higher pricing from jurisdictional rate cases primarily at Duke Energy Carolinas, Duke Energy Indiana, Duke Energy Florida and Duke Energy Progress;

• a $550 million increase in storm recovery revenues at Duke Energy Florida;

• a $244 million increase in weather-normal retail sales volumes;

• a $112 million increase in rider revenues primarily due to the SPP at Duke Energy Florida, the North Carolina Municipal Power Agency (NCEMPA) rider at Duke Energy Progress, as well as the Uncollectible Expense Riders and Distribution Capital Investment Rider and higher OVEC rider collections and OVEC sales into PJM at Duke Energy Ohio;

• an $82 million increase in other revenues due to higher transmission revenues across all jurisdictions and higher Clean Energy Connection subscription revenues at Duke Energy Florida; and

• a $60 million increase in retail sales due to favorable weather compared to prior year.

Partially offset by:

• a $978 million decrease in fuel revenues primarily due to net lower rates in the current year, partially offset by higher volumes.

Operating Expenses . The variance was driven primarily by:

• a $781 million increase in operation, maintenance and other primarily driven by higher storm amortization at Duke Energy Florida, increased litigation and environmental cos ts, as well as joint owner reimbur sements in the prior year at Duke Energy Carolinas, an increase in TDSIC rider amortizations at Duke Energy Indiana, increased customer products and services program costs and higher employee-related expenses across all jurisdictions, partially offset by lower storm costs in the current year at Duke Energy Progress, Duke Energy Carolinas and Duke Energy Florida;

• a $361 million increase in depreciation and amortization primarily due to higher depreciable base across all jurisdictions and higher depreciation rates driven by rate cases; and

• a $110 million increase in property and other taxes due to a higher base on which property taxes are levied.

Partially offset by:

• a $940 million decrease in fuel used in electric generation and purchased power primarily due to lower fuel cost recovery and lower purchased power driven by the expiration of contracts in the prior year at Duke Energy Florida and higher recovery of fuel expense in the prior year at Duke Energy Carolinas, partially offset by higher fuel costs and purchased power at Duke Energy Progress and Duke Energy Ohio; and

• a $40 million decrease in impairment of assets and other charges primarily related to the 2024 South Carolina rate case order in the prior year at Duke Energy Carolinas and Duke Energy Progress.

Other Income and Expense. The increase was primarily driven by higher AFUDC equity base and rates compared to the prior year across all jurisdictions.

Interest Expense. The increase was primarily driven by higher outstanding debt balances, current year return on deferred nuclear PTC liability, absence of prior year return on deferred South Carolina grid costs, partially offset by lower intercompany interest expense and current year return on deferred storm costs at Duke Energy Carolinas and Duke Energy Progress.

Income Tax Expense. The increase in tax expense was primarily due to an increase in pretax income, mostly offset by an increase in the amortization of nuclear PTCs, investment tax credits and EDIT. The ETRs for the nine months ended September 30, 2025, and 2024, were 13.4% and 14.8%, respectively. The decrease in the ETR was primarily due to an increase in the amortization of nuclear PTCs and investment tax credits.

Operating Expenses. The variance was driven primarily by:

• a $586 million increase in operation, maintenance and other primarily due to higher storm amortization;

• a $65 million increase in depreciation and amortization primarily due to higher depreciable base; and

• a $39 million increase in property and other taxes primarily due to higher base upon which property taxes are levied and higher gross receipts tax driven by higher revenues.

Partially offset by:

• a $455 million decrease in fuel used in electric generation and purchased power primarily due to lower fuel cost recovery and lower purchased power costs driven by the expiration of contracts in the prior year, partially offset by higher fuel costs driven by higher natural gas prices.

Interest Expense. The increase was primarily driven by higher outstanding debt balances and interest rates.

Income Tax Expense. The increase in tax expense was primarily due to an increase in pretax income, partially offset by an increase in solar PTCs.

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. In 2024, Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida began monetizing tax credits in the transferability markets established by the IRA and are working with the state utility commissions on the appropriate regulatory process to pass the net realizable value back to customers over time. See Note 17 to the Condensed Consolidated Financial Statements, “Income Taxes,” for further information . Duke Energy’s Annual Report on Form 10-K for the year ended December 31, 2024, included a summary and detailed discussion of projected primary sources and uses of cash for 2025 to 2027.

In 2025, Duke Energy executed several equity forward sales agreements as part of the ATM program. Settlement of the forward sales agreements is expected to occur by December 31, 2026. See Note 15 to the Condensed Consolidated Financial Statements, “Stockholders’ Equity” for further details.

In March 2025, Duke Energy extended the termination date of its existing Master Credit Facility to March 2030 and increased its capacity from $9 billion to $10 billion. As of September 30, 2025, Duke Energy had $688 million of cash on hand and $7.5 billion available under its Master Cr edit 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.

See Note 2 to the Condensed Consolidated Financial Statements, "Dispositions," for the timing and use of final proceeds received in April 2025 from the sale of certain Commercial Renewables assets to affiliates of Brookfield.

In July, Piedmont entered into an agreement with Spire Inc., to sell Piedmont’s Tennessee business for $2.48 billion. Piedmont expects to complete the sale on March 31, 2026, and proceeds are expected to be used for debt reduction at Piedmont and to efficiently fund Duke Energy's capital plan, primarily by displacing the issuance of common equity in the near term. See Note 2 to the Condensed Consolidated Financial Statements, "Dispositions," for further details.

In August 2025, Duke Energy, Progress Energy and Florida Progress entered into an investment agreement for Florida Progress to receive $6 billion in exchange for a 19.7% indirect investment in Duke Energy Florida. The transaction is expected to be completed through a series of closings through June 30, 2028. Proceeds from the minority interest investment are expected to be used to efficiently fund Duke Energy’s growing capital and investment expenditures plan, primarily by displacing certain previously planned issuances of long-term debt and common equity through 2029. See Note 2 to the Condensed Consolidated Financial Statements, "Dispositions," for information on the timing and use of proceeds related to the transaction.

Debt

As discussed in Note 13 to the Condensed Consolidated Financial Statements, "Variable Interest Entities," Duke Energy Carolinas terminated and repaid DERF in January 2025 and Duke Energy Progress terminated and repaid DEPR in March 2025. As a result of these repayments, DERF and DEPR have ceased operations.

MD&A			LIQUIDITY AND CAPITAL RESOURCES

From August through October 2024, a series of major storm events occurred that resulted in significant damage to utility infrastructure within our service territories and primarily impacted Duke Energy Carolinas', Duke Energy Progress' and Duke Energy Florida's electric utility operations. As discussed in Note 4, to the Condensed Consolidated Financial Statements, "Regulatory Matters," hurricanes Debby, Helene and Milton caused widespread outages and included unprecedented damage to certain assets, including the hardest-hit areas on the western coast of Florida and certain regions in western North Carolina and upstate South Carolina. Funding restoration activities and, in some cases, the complete rebuild of critical infrastructure, for a series of sequential events of this magnitude have resulted in incremental financing needs until cost recovery occurs. See "Matters Impacting Future Results" for further details and Note 6 to the Condensed Consolidated Financial Statements, "Debt and Credit Facilities," for information regarding term loans executed in response to these major storm events and storm recovery bonds issued in September 2025.

Additionally, see Note 6 for information related to the Duke Energy (Parent) and Piedmont term loans executed in the third quarter of 2025.

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, 2024, 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.

GHG Standards and Guidelines

In April 2024, the EPA issued final rules 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. Duke Energy is participating in legal challenges to EPA Rule 111 as a member of Electric Generators for a Sensible Transition, a coalition of similarly affected utilities, and as a member of a utility trade group. The litigation is currently pending in the U.S. Court of Appeals for the District of Columbia Circuit (the Court). On February 5, 2025, the EPA requested the Court to withhold issuing an opinion and place the case in a 60-day abeyance to allow time for new EPA leadership to review the issues and EPA Rule 111 to determine how they wish to proceed. On February 19, 2025, the Court granted the EPA’s request. On April 21, 2025, the EPA filed a motion with the Court requesting a continuing abeyance while it conducts a new notice-and-comment rulemaking to reconsider the challenged EPA Rule 111. As part of this request, the EPA indicated it intended to issue a final rule by December 2025. On April 25, 2025, the Court granted the EPA’s motion and ordered that the litigation continue to remain in abeyance pending further order of the Court. On June 17, 2025, the EPA published a proposed rule to repeal EPA Rule 111 based on a finding that fossil fuel-fired power plants “do not contribute significantly to dangerous air pollution” under the meaning of section 111 of the Clean Air Act. The EPA also published an alternative proposal to repeal a narrower set of requirements leaving in place only GHG emission standards for new and reconstructed stationary combustion turbine electric generating units. Comments on the proposed rule were due by August 7, 2025.

120


MD&A			OTHER MATTERS

Coal Combustion Residuals

In April 2024, the EPA issued the 2024 CCR Rule, which significantly expands the scope of the 2015 CCR Rule by establishing regulatory requirements for inactive surface impoundments at retired generating facilities (Legacy CCR Surface Impoundments). Duke Energy, as part of a group of similarly affected electric utilities, filed a petition to challenge the 2024 CCR Rule in the U.S. Court of Appeals for the District of Columbia Circuit (the Court) on August 6, 2024. On February 13, 2025, the EPA requested the Court to withhold issuing an opinion and place the case in a 120-day abeyance to allow time for new EPA leadership to review the issues and the 2024 CCR Rule to determine how they wish to proceed. On that same day, the Court granted EPA’s motion to hold the case in abeyance pending further order of the Court. On June 13, 2025, the EPA requested, and the Court granted, a 60-day extension of the abeyance to give the agency time to “decide the full scope of reconsideration.” On August 11, 2025, the EPA filed a motion to govern further proceedings in the legacy CCR surface impoundments rule litigation, and on August 13, 2025, the Court granted an abeyance in the case until December 15, 2025.

South Carolina Energy Security Act

Act 41, also referred to as the South Carolina Energy Security Act, was signed into law on May 12, 2025. The law promotes evaluating new generation resources, including hydro pumped storage, hydrogen-capable natural gas, and advanced nu clear, while streamlining siting, permitting and construction of certain new resources located in South Carolina. Act 41 establishes a new process for evaluating new potential generation projects over 75 MW located in North Carolina that are planned to serve South Carolina retail customers. This legislation also establishes an electric rate stabilization mechanism for electric utilities to elect into a framework that provides for annual adjustments to base rates, including for CWIP and other cost categories. Electric utilities electing the mechanism must file a general rate case at least every five years.

North Carolina Power Bill Reduction Act

In 2021, the state of North Carolina passed HB951, which among other things, directed the NCUC to develop and approve a carbon reduction plan that would target a 70% reduction in CO 2 emissions from Duke Energy Progress' and Duke Energy Carolinas' electric generation in the state by 2030 and carbon neutrality by 2050, considering all resource options and the latest technolog y, while balancing affordability and reliability for customers. On July 29, 2025, North Carolina Senate Bill 266, or the Power Bill Reduction Act (SB266), was passed into law which retained HB951's 2050 carbon neutrality goal but eliminated the state's interim 2030 carbon reduction target and implemented other actions designed to reduce electricity costs for customers including enhanced cost recovery mechanisms for baseload generation by establishing an annual CWIP recovery for baseload generation and a construction project monitoring process. SB266 also provides more timely recovery of fuel costs, allows for the recovery of CTs in MYRP proceedings and authorizes the prudent continued use of securitization for certain costs and investments serving North Carolina retail electric customers, including increasing the eligible securitization amounts for sub-critical coal assets up to 100% of their respective net book value upon retirement.

Carolinas Resource Plan

On October 1, 2025, Duke Energy Carolinas and Duke Energy Progress filed their systemwide 2025 Carolinas Resource Plan (the 2025 Plan) with the NCUC, which builds upon the approved 2023 Carolinas Resource Plan, outlines development and procurement activities related to a diverse set of generation assets and presents an updated execution strategy to meet growing energy demands reliably and cost-effectively in the coming decades. A hearing is anticipated in the second quarter of 2026, and an order from the NCUC is expected to be issued by December 31, 2026 . The 2025 Plan is expected to be filed with the PSCSC in November 2025.

For open litigation, unless otherwise noted, Duke Energy cannot predict the outcome or ultimate resolution of these matters.

MTBE Litigation

In December 2017, the state of Maryland filed suit in Baltimore City Circuit Court against Duke Energy Merchants and other defendants alleging contamination of state waters by MTBE leaking from gasoline storage tanks and is seeking an unspecified amount of monetary damages. MTBE is a gasoline additive intended to increase the oxygen levels in gasoline and make it burn cleaner. The case was removed from Baltimore City Circuit Court to federal District Court. Initial motions to dismiss filed by the defendants were denied by the court in September 2019, and the matter is now in discovery. In December 2020, the plaintiff and defendants selected 50 focus sites, none of which have any ties to Duke Energy Merchants. Discovery will be specific to those sites. Duke Energy Merchants has reached an agreement in principle with the state of Maryland to resolve the litigation. The settlement agreement is being finalized and the amount is not material.

The Town of Carrboro Litigation

On December 4, 2024, the town of Carrboro, North Carolina, filed a lawsuit against Duke Energy in the North Carolina Superior Court, Orange County, alleging that Duke Energy and its predecessor companies knew since the late 1960s that fossil fuel emissions could cause global climate changes and engaged in a campaign to conceal the dangers of fossil fuel emissions from the public, regulators, legislators, and others, resulting in a delayed transition away from fossil fuel emissions and worsening climate change. The lawsuit also alleges that Duke Energy misled the public regarding Duke Energy’s support for, and actions toward, transitioning its fossil fuel portfolio to renewable energy. The damages alleged range from road and stormwater system impacts to increased electricity costs and recurring invasions and interferences from extreme weather events. The lawsuit asserts state law claims for public nuisance, private nuisance, trespass, negligence, and gross negligence, and is seeking an unspecified amount of monetary damages. The case has been transferred to the North Carolina Business Court. Duke Energy filed a motion to dismiss the litigation based on lack of subject matter jurisdiction on March 17, 2025, and filed a motion to dismiss based on failure to state a claim on which relief can be granted on May 9, 2025. Oral argument regarding Duke Energy's motions to dismiss was held on September 25, 2025. As requested by the court, supplemental briefing addressing various aspects of causation, including traceability and proximate cause, was filed on October 25, 2025.
