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 reducing carbon emissions, while balancing customer reliability and keeping costs as low as possible for our customers;
◦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, particularly in periods of heightened customer affordability concerns, bill volatility or public and political scrutiny, 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;
| FORWARD-LOOKING STATEMENTS | |||||
◦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;
◦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, obtaining sufficient skilled labor 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;
◦The (i) failure to realize the anticipated benefits, synergies and value creation expected from the utility combination by which Duke Energy Progress will merge into Duke Energy Carolinas (the Combination), including as a result of difficulties or delays in integrating the contributed assets and operations and/or the incurring of significant costs in connection with the Combination; and (ii) the risk that the combined entity may not perform as expected following the consummation of the Combination due to unforeseen liabilities, its level of indebtedness, integration challenges, market conditions, ratings downgrades or other factors beyond the control of the parties; 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.

However, none of the registrants make any representations as to information related solely to Duke Energy or the subsidiaries of Duke Energy other than itself.
These Condensed Consolidated Financial Statements, in the opinion of the respective companies’ management, reflect all normal recurring adjustments necessary to fairly present the financial position and results of operations of each of the Duke Energy Registrants. Amounts reported in Duke Energy’s interim Condensed Consolidated Statements of Operations and each of the Subsidiary Registrants’ interim Condensed Consolidated Statements of Operations and Comprehensive Income are not necessarily indicative of amounts expected for the respective annual periods due to effects of seasonal temperature variations on energy consumption, regulatory rulings, timing of maintenance on electric generating units, changes in mark-to-market valuations, changing commodity prices and other factors.
In preparing financial statements that conform to GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
BASIS OF CONSOLIDATION
These Condensed Consolidated Financial Statements include, after eliminating intercompany transactions and balances, the accounts of the Duke Energy Registrants and subsidiaries or VIEs where the respective Duke Energy Registrants have control. See Note 12 for additional information on VIEs. These Condensed Consolidated Financial Statements also reflect the Duke Energy Registrants’ proportionate share of certain jointly owned generation and transmission facilities.
Discontinued Operations
Duke Energy has elected to present cash flows of discontinued operations combined with cash flows of continuing operations. 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. See Note 2 for discussion of discontinued operations related to the Commercial Renewables Disposal Groups.

OTHER NONCURRENT ASSETS
Duke Energy, through a nonregulated subsidiary, was the winning bidder in the Carolina Long Bay offshore wind auction in May 2022. The rights acquired through the auction are recorded in Other within Other noncurrent assets on Duke Energy's Condensed Consolidated Balance Sheets and had a carrying value of approximately $150 million as of June 30, 2026, and December 31, 2025. The auction consideration consisted of approximately $129 million of cash payments, as well as bid credits associated with commitments made by Duke Energy to support development of the U.S. offshore wind industry. The carrying value of the offshore wind rights includes $21 million attributable to these bid credits, with corresponding obligations recorded in Other within Other noncurrent liabilities on Duke Energy's Condensed Consolidated Balance Sheets.
In June 2026, Duke Energy entered into a settlement agreement with the United States Department of the Interior to accept cancellation of its rights to develop offshore wind projects in Carolina Long Bay and related commitments associated with those rights. Under the settlement agreement, Duke Energy will receive $129 million upon satisfaction of specified conditions, including reinvestment in certain dispatchable generating resources and grid infrastructure projects that would enhance the reliability and resiliency of the electric grid, as well as completion of an independent third-party audit of related project costs. The investment in qualifying infrastructure projects is expected to be completed by the end of 2026.
As of June 30, 2026, the conditions required to receive the settlement proceeds had not been satisfied. Accordingly, the offshore wind rights and related bid credits have not been derecognized and no receivable has been recognized. Management evaluated the carrying value of the offshore wind rights and concluded that no impairment charge was required as of June 30, 2026. In performing this assessment, management considered the expected settlement proceeds together with the anticipated extinguishment of the related obligations associated with the bid-credit commitments. Upon satisfaction of the conditions and receipt of the settlement proceeds, Duke Energy expects to derecognize the offshore wind rights and the related bid-credit obligations.

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.
Outstanding obligations that have been confirmed to the financial institution are as follows:

The following new accounting standards have been issued but not yet adopted by the Duke Energy Registrants as of June 30, 2026.
Disaggregation of Income Statement Expenses. In November 2024, the Financial Accounting Standards Board (FASB) issued accounting guidance that requires additional disclosures regarding certain income statement expense captions. The guidance does not change the expense captions presented on the Condensed Consolidated Statements of Operations but requires disclosure in the notes to the financial statements of specified expense categories included within certain expense captions. For the Duke Energy Registrants, the amendments are effective for fiscal years beginning after December 15, 2026, and interim reporting periods within fiscal years beginning after December 15, 2027, with early adoption permitted. Duke Energy is currently evaluating the impact of this guidance on its financial statement disclosures and does not expect adoption of the guidance to have an impact on results of operations, cash flows or financial condition.
Environmental Credits and Environmental Credit Obligations. In May 2026, the FASB issued accounting guidance that establishes recognition, measurement, presentation and disclosure requirements for environmental credits and environmental credit obligations. For the Duke Energy Registrants, the amendments are effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. Duke Energy is currently evaluating the impact of the new guidance, including the transition provisions, and has not yet determined the effect adoption will have on its consolidated financial statements and related disclosures.
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.
On March 3, 2026, Duke Energy, Progress Energy and Florida Progress consummated the first closing (First Closing) of a minority investment in Florida Progress by Investor. The First Closing resulted in Florida Progress issuing 9.19% of its membership interests in exchange for approximately $2.8 billion in cash proceeds. Duke Energy and Progress Energy retained indirect control of these assets, and, therefore, no gain or loss was recognized on their respective Condensed Consolidated Statements of Operations. The difference between the cash consideration received, net of transaction costs of approximately $30 million, and the carrying value of the noncontrolling interest was $1,941 million and was recorded as an increase to equity.
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.
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.
In connection with the First Closing, Investor, Florida Progress, and Progress Energy entered in to an Amended and Restated Limited Liability Company Operating Agreement of Florida Progress (LLC Agreement). The LLC Agreement, among other things, establishes the general framework governing the relationship between Investor and Florida Progress and their respective successors and transferees, as members of Florida Progress. The LLC Agreement also provides Investor with limited governance rights commensurate with its ownership interest in Florida Progress. Under the LLC Agreement, following the First Closing, the board of managers of Florida Progress will consist of 11 managers, two nominated by Investor and nine nominated by Progress Energy. The LLC Agreement contains certain investor protections, including (1) requiring investor approval or the affirmative vote of a manager nominated by the Investor for Florida Progress to make certain major decisions, and (2) providing Investor with the rights to require Progress Energy to acquire Investor's membership interest in Florida Progress under certain specified circumstances (in each case, subject to certain minimum ownership thresholds). Certain transfer restrictions and other transfer rights apply to Investor and Progress Energy under the LLC Agreement.

Sale of Piedmont's Tennessee Business
In July 2025, Piedmont entered into a purchase agreement with Spire Inc., a Missouri corporation, for the sale of Piedmont's Tennessee business. Piedmont’s Tennessee business was included within the GU&I segment of Duke Energy and Piedmont prior to its sale. In the third quarter of 2025, Duke Energy and Piedmont reclassified the Piedmont Tennessee Disposal Group to assets held for sale. 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.
On March 16, 2026, the TPUC approved the transaction and Piedmont closed on the sale on March 31, 2026. Piedmont received proceeds of approximately $2.5 billion from the sale, subject to post-closing adjustments, which were partially used for debt reduction at Piedmont, as well as to efficiently fund Duke Energy's capital plan, primarily by displacing the issuance of common equity in the near term. For the six months ended June 30, 2026, Duke Energy and Piedmont recorded pretax gains on the sale of $368 million and $652 million, respectively, in Gains on Sales of Other Assets and Other, net, in the Condensed Consolidated Statements of Operations. See Note 6 for further information on the repayment of Piedmont's term loan facility in March 2026.
Sale of Commercial Renewables Disposal Groups
The Commercial Renewables Disposal Groups were classified as held for sale and as discontinued operations in the fourth quarter of 2022.
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 an affiliate of Brookfield Renewable Partners L.P. 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. On April 28, 2025, Duke Energy received the remaining sale proceeds from Brookfield Renewable Partners L.P. In January 2025, a sale of the remaining Commercial Renewables business assets was completed and proceeds from that disposition were not material.
During the six months ended June 30, 2025, Income From Discontinued Operations, net of tax in Duke Energy's Condensed Consolidated Statements of Operations related to the Commercial Renewables Disposal Groups was not material.
During the three months ended March 31, 2026, Duke Energy resolved an outstanding liability related to the Commercial Renewables Disposal Groups. As a result of this resolution, Duke Energy recognized $18 million of pretax earnings included in Income From Discontinued Operations, net of tax on Duke Energy's Condensed Consolidated Statements of Operations.
Duke Energy has elected not to separately disclose discontinued operations on Duke Energy's Condensed Consolidated Statements of Cash Flows. The cash flows from discontinued operations related to the Commercial Renewables Disposal Groups were not material for the six months ended June 30, 2026, and 2025.

Winter Storm Fern
In late January 2026, severe weather associated with Winter Storm Fern moved across the eastern U.S. and impacted all of Duke Energy's service territories, with damage primarily occurring in the Duke Energy Carolinas and Duke Energy Progress territories in North Carolina and South Carolina. Approximately 200,000 customers were impacted across Duke Energy's system. Total storm restoration costs, including capital expenditures, for Duke Energy are estimated to be $268 million, which includes $177 million for Duke Energy Carolinas and $91 million for Duke Energy Progress. Incremental storm restoration costs related to operation and maintenance activities in excess of amounts in base rates were charged to storm reserves or deferred as regulatory assets, where applicable, and will be reviewed for recovery in future regulatory proceedings. As of June 30, 2026, the operations and maintenance expense amounts deferred in Regulatory assets within Other Noncurrent Assets on the Condensed Consolidated Balance Sheets were $146 million and $63 million for Duke Energy Carolinas and Duke Energy Progress, respectively. On July 6, 2026, Duke Energy Carolinas and the North Carolina Public Staff entered into a stipulation in the ongoing 2025 Duke Energy Carolinas' North Carolina rate case resolving certain issues regarding storm restoration cost recovery. Under the stipulation, the parties agreed that eligible Winter Storm Fern operation and maintenance restoration costs, without carrying costs, shall be included in the revenue requirement and netted against the Hurricane Helene over-securitization amount, subject to audit by the North Carolina Public Staff and a final true up in the next general rate case. The stipulation is subject to approval by the NCUC as part of ongoing proceedings in the 2025 Duke Energy Carolinas' North Carolina rate case. See below for additional information regarding the 2025 North Carolina rate cases.
On April 14, 2026, Duke Energy Carolinas and Duke Energy Progress filed interim requests with the NCUC related to fuel and purchased power costs incurred during severe winter weather and record customer energy demand experienced in the first quarter of 2026. The interim filings requested recovery of underrecovered fuel and purchased power costs of $500 million for Duke Energy Carolinas and $309 million for Duke Energy Progress, over a period of 19 months. These pass-through costs represent actual expenses, without markup, necessary to supply power, as allowed under the North Carolina Power Bill Reduction Act (SB266). SB266 implemented actions designed to reduce electricity costs for customers including enhanced cost recovery mechanisms and more timely recovery of fuel costs, among other actions. The NCUC approved the proposed 19 month recovery period in May 2026, and new fuel rider rates went into effect June 1, 2026.
Duke Energy Carolinas and Duke Energy Progress
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 South 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. The targeted effective date is January 1, 2027. On January 30, 2026, FERC issued an order authorizing the combination as consistent with the public interest.
59
| FINANCIAL STATEMENTS | REGULATORY MATTERS | ||||
The North Carolina Public Staff and intervenors in the NCUC proceeding filed testimony advocating, in part, that the NCUC impose certain conditions for the combination to go forward, including conditions related to treatment of costs to achieve and future rate consolidation. In the South Carolina proceeding, the South Carolina Office of Regulatory Staff and intervenors filed testimony recommending that the PSCSC condition approval of the combination on additional requirements, including addressing the identification, allocation and recovery of cost impacts and costs to achieve, as well as the treatment of benefits.
On February 24, 2026, the Companies reached a comprehensive settlement with the North Carolina Public Staff and certain other intervenors (stipulating parties) in the case, which was filed with NCUC. Subject to approval by the NCUC, the agreement resolved all issues among the North Carolina stipulating parties regarding the combination of Duke Energy Carolinas and Duke Energy Progress. Among other terms, the agreement requires the Companies to guarantee that savings from the combination over a 14-year period will be sufficient to offset the identified impacts to North Carolina retail customers to achieve the combination. The guaranteed savings are calculated based on a combination of capital-related savings associated with Duke Energy Carolinas and Duke Energy Progress' most recent resource planning assumptions, as well as operational savings enabled by the combination expected to accrue following the effective date of the combination. The agreement also permits deferral of costs to achieve, with recovery subject to prudency review, and provides that North Carolina retail customers will make annual Share the Benefits contributions to South Carolina retail customers for a six-year period beginning in 2030. On May 1, 2026, the NCUC issued an order approving the combination consistent with the comprehensive settlement.
On March 6, 2026, the Companies reached a comprehensive settlement with the South Carolina Office of Regulatory Staff and certain other intervenors in the case, which was filed with PSCSC. Subject to approval by the PSCSC, the agreement, which has the same core components as the comprehensive settlement reached in North Carolina, resolved all issues among the South Carolina stipulating parties, regarding the combination of Duke Energy Carolinas and Duke Energy Progress. Among other terms, the agreement requires the Companies to guarantee that savings from the combination over a 14-year period will be sufficient to offset the identified impacts to South Carolina retail customers, including through the receipt of Share the Benefits contributions from North Carolina retail and wholesale customers. On June 3, 2026, the PSCSC issued its final written order approving the combination consistent with the terms of the comprehensive settlement.

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, agreement 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 the 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 15, 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. The 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 COVID-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.
In February 2024, a number of parties filed Notices of Appeal of the December 15, 2023, NCUC order. Notices of Appeal were filed by the Carolina Industrial Group for Fair Utility Rates (CIGFUR) III, a collection of electric membership cooperatives (collectively, the EMCs), and the North Carolina Attorney General’s Office (the AGO). CIGFUR III and the EMCs appealed the interclass subsidy reduction percentage and the Transmission Cost Allocation stipulation. In addition, CIGFUR III appealed the NCUC’s elimination of the equal percentage fuel cost allocation methodology. The AGO appealed several issues, including the authorized ROE and certain rate design and accounting matters. On March 1, 2024, Carolina Utility Customers Association, Inc. appealed several issues, including the authorized ROE and certain rate design and accounting matters. In July 2024, the Supreme Court of North Carolina consolidated these appeals with the parallel appeals of the NCUC's order regarding the Duke Energy Progress PBR application. On May 22, 2026, the Supreme Court of North Carolina affirmed the NCUC order in its entirety. This matter is now fully resolved.

2022 North Carolina Rate Case
In October 2022, Duke Energy Progress filed a PBR application with the NCUC to request an increase in base rate retail revenues. The rate request before the NCUC 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 PIMs as required by HB951.
In April 2023, Duke Energy Progress filed with the NCUC a partial settlement with North Carolina Public Staff, which included agreement on many aspects of Duke Energy Progress' three-year MYRP proposal. In May 2023, CIGFUR II joined this partial settlement and the North Carolina Public Staff and CIGFUR II filed a separate settlement reaching agreement on PIMs, Tracking Metrics and the Residential Decoupling Mechanism under the PBR application.
On August 18, 2023, the NCUC issued an order approving Duke Energy Progress' PBR application, as modified by the partial settlements and the order, including an overall retail revenue increase of $233 million in Year 1, $126 million in Year 2 and $135 million in Year 3, for a combined total of $494 million. Key aspects of the order include the approval of North Carolina retail rate base for the historic base case of approximately $12.2 billion and capital projects and related costs to be included in the three-year MYRP, including $3.5 billion (North Carolina retail allocation) projected to go in service over the MYRP period. The order established an ROE of 9.8% 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 COVID-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 Progress implemented interim rates on June 1, 2023, and implemented revised Year 1 rates and the residential decoupling on October 1, 2023.
In October 2023, CIGFUR II and Haywood Electric Membership Corporation each filed a Notice of Appeal of the August 18, 2023 NCUC order. Both parties appealed certain matters that do not impact the overall revenue requirement in the rate case. Specifically, they appealed the interclass subsidy reduction percentage, and CIGFUR II also appealed the Customer Assistance Program and the equal percentage fuel cost allocation methodology. In November 2023, the AGO filed a Notice of Cross Appeal of the NCUC's determination regarding the exclusion of electric vehicle revenue from the residential decoupling mechanism. In November 2023, Duke Energy Progress, the North Carolina Public Staff, CIGFUR II, and a number of other parties reached a settlement pursuant to which CIGFUR II agreed not to pursue its appeal of the Customer Assistance Program. In July 2024, the Supreme Court of North Carolina consolidated these appeals with the parallel appeals of the NCUC's order regarding the Duke Energy Carolinas PBR application. On May 22, 2026, the Supreme Court of North Carolina affirmed the NCUC order in its entirety. This matter is now fully resolved.
2025 North Carolina Rate Case
On November 20, 2025, Duke Energy Progress filed a 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 a two-year MYRP period. In addition to the MYRP, the PBR application included an Earnings Sharing Mechanism, Residential Decoupling Mechanism and PIMs. The overall net retail revenue increase originally requested was $529 million in Year 1 and $200 million in Year 2, for a combined total of $729 million or 15.1%, including the flow back of PTC benefits to customers through a proposed PTC rider similar to Duke Energy Carolinas. The application also requested an ROE of 10.95% and an equity ratio of 53%. The requested rate increase is driven primarily by major transmission and distribution investments made since the last rate case, projected capital investments included in the MYRP and investments in energy storage and solar assets.
On July 17, 2026, Duke Energy Carolinas, the North Carolina Public Staff, and other intervening parties filed a comprehensive settlement agreement with the NCUC resolving all remaining revenue requirement issues in the Duke Energy Carolinas rate case proceeding and agreed to pursue good faith settlement discussions using a substantially similar framework in the ongoing Duke Energy Progress rate case proceeding. Consistent with the settlement framework, Duke Energy Progress recorded a $22 million charge within Impairment of assets and other charges in the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and six months ended June 30, 2026. On July 24, 2026, Duke Energy Progress filed rebuttal testimony incorporating six adjustments to its application, including a reduction in the requested ROE, which reduced the requested increase to approximately $610 million over the two-year period, for a cumulative increase of 12.3%.
Duke Energy Progress has requested that Year 1 rates become effective no later than January 1, 2027. The evidentiary hearing is scheduled to commence on August 11, 2026 and an order is expected by November 2026.

South Carolina Electric Rate Stabilization Adjustment Filing
On March 13, 2026, Duke Energy Progress filed a request with the PSCSC to adjust electric rates under the new electric Rate Stabilization Adjustment (eRSA) framework, aimed at supporting investments and improving reliability. This filing represents the first electric utility proceeding under the eRSA in South Carolina. Established by South Carolina’s 2025 Energy Security Act, the eRSA allows electric utilities to seek annual rate adjustments using standardized historical data, with continued oversight based on prior base rate case outcomes. Duke Energy Progress' request stems from investments made in 2025 for grid and reliability improvements not covered in its base rate case, with the law permitting adjustments when calendar-year earned returns deviate by more than 0.50% from authorized returns. The filing requested an annual revenue increase of $37 million, reflecting an overall rate increase of 5.5% across customer classes and resulting in a projected ROE of 9.99%, consistent with the ROE authorized in the 2025 South Carolina Rate Case.
On June 15, 2026, Duke Energy Progress and the South Carolina Office of Regulatory Staff (ORS) filed a stipulation resolving audit adjustments and agreeing to a revenue requirement increase of $24 million. On June 29, 2026, the PSCSC issued a directive indicating its intent to deny the stipulation and Duke Energy Progress' election under the eRSA framework, citing Duke Energy Progress' failure to file a quarterly monitoring report by June 15, 2026, for the 12-month period ending March 31, 2026. Duke Energy Progress filed a request for reconsideration of that directive on July 2, 2026. On July 13, 2026, the PSCSC issued a further directive concluding that electric utilities electing into the eRSA are not eligible to implement rate adjustments until the year following their election. On July 14, 2026, Duke Energy Progress filed an objection and request that the PSCSC rescind or amend this directive prior to issuing a final order, asserting that the directive is inconsistent with the eRSA statute and prior PSCSC precedent in natural gas rate stabilization proceedings, and was based on legal arguments not previously raised in the proceeding. On July 15, 2026, the PSCSC issued an order denying the stipulation and rejecting Duke Energy Progress' proposed rate adjustment in 2026.
On July 23, 2026, Duke Energy Progress filed a petition for reconsideration of the PSCSC's order and is pursuing additional legal and regulatory remedies, including filing an appeal with the South Carolina Supreme Court on July 24, 2026. The ultimate outcome of the proceeding, including the timing and amount of any authorized rate adjustment, remains uncertain.
Person County Combined Cycle CPCNs
On February 7, 2025, Duke Energy Progress filed with the NCUC its application to construct and operate a second 1,360-MW hydrogen-capable, advanced-class CC unit in Person County at the Roxboro Plant. NCEMC has the right to co-own the facilities under its existing supply agreement with Duke Energy Progress. Duke Energy Progress and NCEMC executed the contractual agreements for both units in April 2026, which allows NCEMC to own approximately 225 MW of each unit, for a total of approximately 450 MW. The joint ownership agreement was finalized and executed in June 2026.
Pending regulatory approvals, the unit is targeted to be placed in service by the end of 2029. As part of the application, Duke Energy Progress noted that the recovery of CWIP during the construction period for the proposed facility may be pursued in the future. The 2030 North Carolina retail revenue requirement for the second unit is estimated to be $113 million, representing an approximate average retail rate increase of 2.6% across all classes. The air permit was issued by the NCDEQ in December 2024. On October 16, 2025, the NCUC issued its order granting the CPCN. Construction activities are ongoing at both Person County CC units.
On January 30, 2026, Duke Energy Progress filed an application for out-of-state certificates with the PSCSC requesting that it find that the two new CC units, totaling approximately 2,720 MW, sited at the Person County facilities in North Carolina are in the public convenience and necessity for South Carolina retail customers. On July 23, 2026, the PSCSC issued its order granting the CPCN.
Robinson Subsequent License Renewal
In April 2025, Duke Energy Progress filed an SLR application with the NRC to renew the Robinson facility operating license for an additional 20 years. The current license would have expired in 2030. In March 2026, the NRC approved a final environmental impact statement. On April 23, 2026, the NRC issued the subsequent renewed license for Robinson to continue operations until 2050. This matter is fully resolved.
Duke Energy Florida
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.
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, seeking recovery of approximately $1.1 billion over 12 months beginning with the first billing cycle in March 2025. 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. Approximately $75 million of capital related to these storms will be sought for recovery in future base rate case filings.
On January 5, 2026, Duke Energy Florida filed a notice with the FPSC to stop recovery of the storm cost charge because the costs were fully recovered and the storm reserve was fully replenished earlier than anticipated, primarily due to lower actual incurred storm costs as compared to preliminary estimates. The notice was administratively approved and revised rates with the storm charge removed were effective with the first billing cycle in February 2026. Duke Energy Florida filed documentation evidencing its total Debby, Helene and Milton actual storm costs of $903 million on February 27, 2026. In March 2026, Duke Energy Florida filed a petition to refund approximately $91 million of storm costs that were over-collected. On May 21, 2026, the FPSC issued its order approving the petition. The FPSC is expected to vote at its September 10, 2026 Agenda Conference on Duke Energy Florida's February 27, 2026 filing.

Duke Energy Ohio
Duke Energy Ohio 2022 Natural Gas Base Rate Case
In June 2022, Duke Energy Ohio filed a natural gas base rate case application with the PUCO seeking recovery of capital investments made since Duke Energy Ohio's last natural gas base rate case in 2012. Duke Energy Ohio also sought to adjust the caps on its 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 an annual revenue increase of approximately $32 million 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 October 2024, the OCC filed a Notice of Appeal with the Supreme Court of Ohio. On June 5, 2026, the Supreme Court of Ohio affirmed the PUCO order. This matter is now fully resolved.
Duke Energy Ohio 2026 Electric Rate Case
On March 30, 2026, Duke Energy Ohio filed an electric distribution base rate case with the PUCO, requesting an annualized increase in electric distribution base rates of approximately $90 million. Duke Energy Ohio requested an ROE of 10.5% with an equity ratio of 52.66%. The rate increase is driven by significant infrastructure upgrade investments since the last general rate case. An evidentiary hearing is scheduled to commence on January 20, 2027. New rates are anticipated to go into effect in May 2027.
Duke Energy Ohio 2026 Natural Gas Rate Case
On June 29, 2026, Duke Energy Ohio filed a natural gas base rate case application with the PUCO requesting an annualized increase in natural gas base rates of approximately $102 million, based on a proposed ROE of 10.5% and an equity ratio of 53.14%. The filing would result in an overall average customer rate increase of approximately 9.9%, primarily driven by capital investments to strengthen the natural gas delivery system. An evidentiary hearing is expected in the second quarter of 2027, with new rates anticipated to go into effect in September 2027.
Duke Energy Ohio RTO Adder
On February 24, 2022, the OCC filed a complaint asserting that FERC should reduce the ROE utilized in transmission formula rates for Duke Energy Ohio and certain other transmission providers by eliminating the 50-basis-point adder associated with RTO membership. The OCC contended that the adder was inappropriate because Ohio law requires transmission-owning utilities to participate in the RTO and the adder is only available when RTO membership is voluntary. On December 15, 2022, FERC denied the complaint as it related to Duke Energy Ohio but granted relief with respect to certain other transmission providers.
Following appeals by certain transmission providers, the U.S. Court of Appeals for the Sixth Circuit (Sixth Circuit) reversed FERC's decision on January 17, 2025. The Sixth Circuit held that the 50-basis-point-adder is available only when RTO membership is voluntary. The court further concluded that because Ohio law requires transmission-owning utilities to participate in an RTO, FERC could not lawfully remove the adder from certain Ohio transmission providers while continuing to permit Duke Energy Ohio to recover the adder. The matter was remanded to FERC for further proceedings consistent with the court's decision. As a result of the ruling, Duke Energy Ohio recognized a pretax charge during 2025 that was not material.
On March 26, 2025, the Sixth Circuit denied requests for rehearing. On April 16, 2025, the Sixth Circuit stayed its mandate pending further appeal to the U.S. Supreme Court. On July 17, 2025, Duke Energy Ohio filed a respondent brief with the U.S. Supreme Court seeking review of the Sixth Circuit's decision. On November 10, 2025, the U.S. Supreme Court denied review, and on November 13, 2025, the Sixth Circuit remanded the matter to FERC.
On June 25, 2026, FERC issued an order on remand directing the removal of the ROE adder from Duke Energy Ohio's transmission formula rate and requiring Duke Energy Ohio to provide refunds for the period beginning February 24, 2022. As a result of this order, Duke Energy Ohio recorded a $15 million reduction in Operating Revenues during the three months ended June 30, 2026. As of June 30, 2026, Duke Energy Ohio had recorded a regulatory liability of $20 million related to this matter. Refunds are expected to be issued by the first quarter of 2027. On July 24, 2026, Duke Energy Ohio filed a request for rehearing of FERC's June 25, 2026 order, including whether the order complies with the Federal Power Act's requirements governing changes to existing rates. FERC must act upon the request for rehearing by August 24, 2026, but could issue a further substantive order after that date.
Transmission Cost Allocation Proceedings
Duke Energy Ohio is a member of PJM Interconnection, LLC, the Independent System Operator (ISO) and FERC-approved RTO for the region in which Duke Energy Ohio operates. Duke Energy Ohio and other transmission owners in PJM have turned over control of their transmission facilities and their transmission systems are currently under the RTO dispatch control of PJM. Transmission service is provided on a regionwide, open-access basis using the transmission facilities of the PJM members at rates based on the costs of transmission service.
RTOs like PJM engage in long-term regional planning to ensure the transparent evaluation of transmission facilities and to assist in determining how such projects should be designed and built to meet broader regional needs. Costs are typically recovered from customers who benefit from the upgrades or, for certain larger projects, costs may be shared across the PJM region. Shared costs are determined according to a formula approved by FERC, and the formula relies on a Solution-Based Distribution Factor (DFAX) methodology. PJM has historically used a de minimis threshold in its DFAX methodology that exempts zones from paying a portion of transmission costs if the zone's calculated use of the transmission facility is below 1%. Duke Energy Ohio has historically been below the de minimis threshold for certain transmission projects and, as such, was not allocated respective costs for those projects.

| FINANCIAL STATEMENTS | REGULATORY MATTERS | ||||
From time to time, various parties have challenged cost allocations for specific RTO-area transmission projects, including PJM, at the FERC and other appellate courts. On March 6, 2026, FERC issued a ruling related to these cost challenges that is expected to impact the historical transmission cost allocations of PJM. Specifically, the FERC found that the de minimis threshold used in the DFAX cost allocation methodology is unjust, unreasonable and inconsistent with cost causation. Among other considerations, FERC noted that larger RTO zones typically have higher peak loads and the same DFAX usage value could place a smaller zone above the 1% de minimis threshold – which is based on peak load –resulting in a cost allocation to the smaller zone, while a larger zone with comparable usage would not receive a cost allocation. In conjunction with this ruling, PJM was ordered to file tariff revisions within 90 days, which update the DFAX cost allocation percentages in the tariff based on the elimination of the 1% de minimis threshold. Based on those updated cost allocation percentages, PJM will then need to recalculate costs and issue refunds/surcharges (with interest) going back to June 18, 2015. On April 6, 2026, Duke Energy Ohio, jointly with several other PJM transmission owners, filed for rehearing of the March 6, 2026 order. On May 12, 2026, Duke Energy Ohio, jointly with several of the PJM transmission owners, filed a petition for review of the March 6, 2026 order in the U.S. Court of Appeals for the District of Columbia Circuit. On June 4, 2026, PJM submitted a compliance filing to remove the de minimis threshold from the tariff prospectively, effective June 1, 2026.
Duke Energy Ohio is evaluating the potential impacts of this ruling, including any potential amounts owed to PJM, and required financial statement adjustments and is unable to reasonably estimate the ultimate financial statement impact.
Duke Energy Kentucky 2022 Electric Base Rate Case
In December 2022, Duke Energy Kentucky filed a base rate case with the KPSC driven by capital investments to strengthen the electricity generation and delivery systems along with adjusted depreciation rates for the East Bend and Woodsdale Combustion Turbine generation stations. Duke Energy Kentucky also requested approval for new programs and tariff updates, including a voluntary community-based renewable subscription program and two electric vehicle charging programs. The KPSC issued an order on October 12, 2023, including a $48 million increase in base revenues, an ROE of 9.75% for electric base rates and 9.65% for electric riders and an equity ratio of 52.145%. New rates went into effect October 13, 2023. Duke Energy Kentucky's request to adjust the depreciation rates of East Bend was denied and the KPSC ordered depreciation rates with a 2041 retirement date for the unit. The KPSC approved the request to align depreciation rates of Woodsdale CT with a 2040 retirement date and denied the voluntary community-based renewable subscription program and electric vehicle charging programs.
Revised rates were implemented in August 2024 after a rehearing request. On December 14, 2023, Duke Energy Kentucky filed an appeal with the Franklin County Circuit Court on certain matters for which the KPSC denied rehearing, specifically as it relates to the inclusion of decommissioning costs in depreciation rates for East Bend and Woodsdale. The case is fully briefed and Duke Energy Kentucky is awaiting the scheduling of oral arguments and the outcome of the appeal.
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 certain of 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. On January 26, 2026, the Indiana Supreme Court denied Duke Energy Indiana's and the Indiana Office of Attorney General's petitions. There were no material impacts on the results of operations, cash flows or financial position as a result of this ruling. On March 30, 2026, Duke Energy Indiana filed its Petition and Case-in-Chief for Environmental Cost Rider (ECR) 45, implementing changes directed by the Indiana Court of Appeals decision. Duke Energy Indiana anticipates the IURC will issue an ECR 45 order in the coming months.
2024 Indiana Rate Case
In April 2024, Duke Energy Indiana filed an application with the IURC for a rate increase for retail customers. The request for the 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 energy solutions.
65
| FINANCIAL STATEMENTS | REGULATORY MATTERS | ||||
In connection with this rate case, a $29 million increase in a regulatory liability associated with certain employee post-retirement benefits was recorded in December 2024. 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.
On February 18, 2026, Duke Energy Indiana submitted a second compliance filing in accordance with the IURC’s findings in its order, and the IURC approved the compliance filing on February 25, 2026. On March 20, 2026, the Industrial Group and Indiana Office of Consumer Counselor (OUCC) filed an objection to the Company’s Step 2 compliance filing. On May 27, 2026, the presiding officers denied the objection. On June 4, 2026, the OUCC, the Industrial Group and other intervenors appealed this decision to all of the IURC commissioners.
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 being 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 approximately $3.3 billion, plus actual AFUDC. Duke Energy Indiana proposed recovery of certain facility costs during construction, including AFUDC, through CWIP ratemaking via a proposed Generation Cost Tracker (GCT). 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 GCT. On November 26, 2025, CAC filed a notice of appeal of the IURC's order. Duke Energy Indiana filed a petition to transfer the case to the Indiana Supreme Court. The petition was granted in April 2026, with oral arguments scheduled for September 2026.
In April 2026, Duke Energy Indiana's first GCT tariff factors to recover Cayuga CC CPCN-related costs were effective. These factors will remain in place for approximately six months or until superseded by IURC-approved factors in a subsequent filing. On May 15, 2026, Duke Energy Indiana filed its second GCT tariff for approval to recover Cayuga CC CPCN-related costs. These factors are expected to be effective in the first October 2026 billing cycle and will remain in place for approximately six months or until superseded by IURC-approved factors in a subsequent filing. The estimated average cumulative retail rate impact during construction and initial in-service periods from April 2026 through May 2031 is approximately 5.6%.
Piedmont
2026 South Carolina Rate Case
On April 1, 2026, Piedmont filed an application with the PSCSC for a rate increase for retail customers of approximately $16 million, which represents a 6.3% increase in retail revenues. Piedmont requested an ROE of 10.8% with an equity ratio of 55.09%. The rate increase is driven by significant infrastructure upgrade investments and higher cost of capital since the last general rate case. In its application, Piedmont expressed its intent to resume operating under the South Carolina Rate Stabilization Act prospectively after completion of the rate case. The evidentiary hearing is scheduled to commence on August 20, 2026, with a final decision on or before October 1, 2026. New rates are expected to become effective October 1, 2026.

| FINANCIAL STATEMENTS | COMMITMENTS AND CONTINGENCIES | ||||
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.
The following table contains information regarding reserves for probable and estimable costs related to the various environmental sites. These reserves are recorded in Accounts Payable within Other Current Liabilities and Other within Other Noncurrent Liabilities on the Condensed Consolidated Balance Sheets.

Duke Energy
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. In addition to Duke Energy Carolinas, NTE subsequently amended the complaint to include Duke Energy Progress and Duke Energy Corporation as defendants in the antitrust claims (collectively, the Defendants).
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.
Following completion of discovery, the Defendants filed a motion for summary judgment seeking a ruling in their 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 the Defendants' motion by dismissing NTE's counterclaims that Duke Energy Carolinas and Duke Energy Progress 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 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, the Defendants filed a petition for rehearing, which was denied on November 26, 2024. On February 21, 2025, the Defendants filed a petition seeking review by the U.S. Supreme Court. On January 12, 2026, the U.S. Supreme Court denied the petition seeking review. In March 2026, the parties executed a settlement agreement resolving the entire case and a Stipulation of Dismissal was filed with the court. The amount of the settlement was not material in 2026. This matter is now fully resolved.
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 related to alleged past and ongoing environmental contamination in the Mooresville, North Carolina, area. The lawsuit alleges that Duke Energy disposed of and sold coal ash for use as structural fill, resulting in contamination of soil, groundwater and Lake Norman. The plaintiffs further allege that Duke Energy failed to adequately remediate the contamination, continues to pollute and has negatively impacted property values. The plaintiffs seek unspecified compensatory and punitive damages, injunctive relief to prevent further contamination, remediation of contaminated areas and recovery of 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 plaintiffs' amended complaint and a motion for judgment on the pleadings. Following a hearing on December 29, 2025, the court entered an interim order dismissing the plaintiffs' strict liability claim. On February 4, 2026, the court denied the remainder of Duke Energy's motion for judgment on the pleadings. A scheduling order has been entered in this matter, and the parties are evaluating the possibility of an early mediation.
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 jurisdiction. 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. In response to the amended complaint, defendants filed an omnibus motion to dismiss on December 19, 2025. The court held oral argument on May 13, 2026, and no ruling has been issued to date.
Duke Energy Carolinas
Asbestos-related Injuries and Damages Claims
Duke Energy Carolinas has experienced numerous claims for indemnification and medical cost reimbursement related to asbestos exposure. These claims relate to damages for bodily injuries alleged to have arisen from exposure to or use of asbestos in connection with construction and maintenance activities conducted on its electric generation plants prior to 1985.
Duke Energy Carolinas has recognized asbestos-related reserves of $377 million at June 30, 2026, and $395 million at December 31, 2025. 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 $556 million at June 30, 2026, and $555 million at December 31, 2025. 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 for the asbestos-related injuries and damages is $9 million as of June 30, 2026, and December 31, 2025, 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.
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.

In June 2026, Duke Energy Kentucky priced an aggregate principal amount of $100 million senior unsecured debentures through a private placement offering. The debentures are expected to be issued on September 9, 2026, and will consist of two tranches, $50 million with a coupon of 5.79% maturing September 2033 and $50 million with a coupon of 6.13% maturing September 2038. Proceeds are expected to be used to pay down short-term debt and for general corporate purposes.
Duke Energy (Parent) Convertible Senior Notes
On April 15, 2026, Duke Energy (Parent) settled all of its outstanding 4.125% Convertible Senior Notes due April 2026 (the “Notes due 2026”) upon conversion. In accordance with the terms of the indenture and at the Company's election, Duke Energy paid approximately $1.7 billion in cash equal to the aggregate principal amount of the Notes due 2026 and issued 1.4 million shares of its common stock to settle the conversion premium, as the conversion value exceeded the principal amount of the Notes due 2026.
In March 2026, Duke Energy (Parent) completed the sale of $1.5 billion 3.000% Convertible Senior Notes due March 2029 (convertible notes). The convertible notes are senior unsecured obligations of Duke Energy, and will mature on March 15, 2029, unless earlier converted or repurchased in accordance with their terms. The convertible notes bear interest at a fixed rate of 3.000% per year, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2026. Proceeds were used to repay a portion of $1.7 billion of outstanding convertible senior notes due April 2026 and for general corporate purposes.

| FINANCIAL STATEMENTS | DEBT AND CREDIT FACILITIES | ||||
Prior to the close of business on the business day immediately preceding December 15, 2028, the convertible notes will be convertible at the option of the holders when the following conditions are met:
•during any calendar quarter commencing after the calendar quarter ending on June 30, 2026 (and only during such calendar quarter), if the last reported sale price of Duke Energy common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
•during the five consecutive business day period after any 10 consecutive trading day period (the measurement period) in which the trading price, as defined, per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of Duke Energy common stock and the conversion rate on each such trading day; or
•upon the occurrence of specified corporate events described in the indenture agreement.
On or after December 15, 2028, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the convertible notes may convert all or any portion of their convertible notes at their option at any time at the conversion rate then in effect, irrespective of these conditions. Duke Energy will settle conversions of the convertible notes by paying cash up to the aggregate principal amount of the convertible notes to be converted and paying or delivering, as the case may be, cash, shares of Duke Energy's common stock, $0.001 par value per share, or a combination of cash and shares of its common stock, at its election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the convertible notes being converted.
The conversion rate for the convertible notes is initially 6.2277 shares of Duke Energy's common stock per $1,000 principal amount of convertible notes. The initial conversion price of the convertible notes represents a premium of approximately 22.5% over the last reported sale price of Duke Energy’s common stock on the NYSE on March 9, 2026. The conversion rate and the corresponding conversion price will not be adjusted for any accrued and unpaid interest but will be subject to adjustment in some instances, such as stock splits or share combinations, certain distributions to common stockholders, or tender offers at off-market rates. The changes in the conversion rates are intended to make convertible note holders whole for changes in the fair value of Duke Energy common stock resulting from such events. Duke Energy may not redeem the convertible notes prior to the maturity date.
Duke Energy issued the convertible notes pursuant to an indenture, dated as of March 12, 2026, by and between Duke Energy and The Bank of New York Mellon Trust Company, N.A., as trustee. The terms of the convertible notes include customary fundamental change provisions that require repayment of the notes with interest upon certain events, such as a stockholder-approved plan of liquidation or if Duke Energy's common stock ceases to be listed on the NYSE.

9. DERIVATIVES AND HEDGING
The Duke Energy Registrants use commodity, interest rate and foreign currency contracts to manage commodity price risk, interest rate risk and foreign currency exchange rate risk. The primary use of commodity derivatives is to hedge the generation portfolio against changes in the prices of electricity and natural gas. Piedmont enters into natural gas supply contracts to provide diversification, reliability and natural gas cost benefits to its customers. Interest rate derivatives are used to manage interest rate risk associated with borrowings. Foreign currency derivatives are used to manage risk related to foreign currency exchange rates on certain issuances of debt.
All derivative instruments not identified as NPNS are recorded at fair value as assets or liabilities on the Condensed Consolidated Balance Sheets. Cash collateral related to derivative instruments executed under master netting arrangements is offset against the collateralized derivatives on the Condensed Consolidated Balance Sheets. The cash impacts of settled derivatives are recorded as operating activities 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 six months ended June 30, 2026, and 2025, 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.
Cash Flow Hedges
For derivatives designated as hedging the exposure to variable cash flows of a future transaction, referred to as a cash flow hedge, 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. Gains and losses reclassified out of accumulated other comprehensive income (loss) for the three and six months ended June 30, 2026, and 2025, were not material. Duke Energy’s commodity derivatives designated as hedges include fixed-price energy futures at Duke Energy Ohio.
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.

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.
The following table shows Duke Energy's outstanding derivatives related to foreign currency risk at June 30, 2026.

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 objectives and 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 June 30, 2026, and December 31, 2025.
Other Investments amounts are recorded in Other within Other Noncurrent Assets on the Condensed Consolidated Balance Sheets.

11. FAIR VALUE MEASUREMENTS
Fair value is the exchange price to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The fair value definition focuses on an exit price versus the acquisition cost. Fair value measurements use market data or assumptions market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs may be readily observable, corroborated by market data or generally unobservable. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. A midmarket pricing convention (the midpoint price between bid and ask prices) is permitted for use as a practical expedient.
Fair value measurements are classified in three levels based on the fair value hierarchy as defined by GAAP. Certain investments are not categorized within the fair value hierarchy. These investments are measured at fair value using the net asset value per share practical expedient. The net asset value is derived based on the investment cost, less any impairment, plus or minus changes resulting from observable price changes for an identical or similar investment of the same issuer.
Fair value accounting guidance permits entities to elect to measure certain financial instruments that are not required to be accounted for at fair value, such as equity method investments or the Company’s 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.
83
| 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, 2025, for a discussion of the valuation of goodwill and intangible assets.

At both June 30, 2026, and December 31, 2025, fair value of cash and cash equivalents, accounts and notes receivable, accounts payable, notes payable and commercial paper and nonrecourse notes payable of VIEs are not materially different from their carrying amounts because of the short-term nature of these instruments and/or because the stated rates approximate market rates.
12. 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 six months ended June 30, 2026, and the year ended December 31, 2025, or is expected to be provided in the future that was not previously contractually required.
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.
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.

Procurement Companies
Duke Energy Florida Purchasing Company, LLC (DEF ProCo) and Duke Energy Indiana Purchasing Company, LLC (DEI ProCo) are wholly owned special purpose subsidiaries and the primary procurement agents for equipment, materials and supplies of Duke Energy Florida (beginning in 2023) and Duke Energy Indiana (beginning in 2026). The ProCos interact with third-party suppliers on Duke Energy Florida’s and Duke Energy Indiana's behalf with credit and risk support provided by Duke Energy Florida and Duke Energy Indiana. Both ProCos are qualified resellers under their respective state's tax laws and convey acquired assets to the utilities through leases on each acquired asset.
These entities are considered VIEs primarily because their equity capitalization is insufficient to support their operations. Duke Energy Florida and Duke Energy Indiana have the power to direct the significant activities of the VIEs as described above and therefore Duke Energy Florida and Duke Energy Indiana are considered the primary beneficiaries and consolidate each respective procurement company.
The following table summarizes the impact of these VIEs on Duke Energy Florida's and Duke Energy Indiana's Consolidated Balance Sheets.

NON-CONSOLIDATED VIEs
Natural Gas Investments
Duke Energy has investments in various joint ventures, including transmission pipeline 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.

13. REVENUE
Duke Energy earns substantially all of its revenues through its reportable segments, EU&I and GU&I.
Electric Utilities and Infrastructure
EU&I earns the majority of its revenues through retail and wholesale electric service through the generation, transmission, distribution and sale of electricity. Duke Energy generally provides retail and wholesale electric service customers with their full electric load requirements or with supplemental load requirements when the customer has other sources of electricity.
The majority of wholesale revenues are full requirements contracts where the customers purchase the substantial majority of their energy needs and do not have a fixed quantity of contractually required energy or capacity. As such, related forecasted revenues are considered optional purchases. Supplemental requirements contracts that include contracted blocks of energy and capacity at contractually fixed prices have the following estimated remaining performance obligations as of June 30, 2026:
| Remaining Performance Obligations | |||||||||||||||||||||||

| Duke Energy Indiana | 2 | 2 | — | — | — | — | 4 | ||||||||||||||||
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 June 30, 2026, are as follows:

Trade and other receivables are evaluated based on an estimate of the risk of loss over the life of the receivable and current and historical conditions using supportable assumptions. Management evaluates the risk of loss for trade and other receivables by comparing the historical write-off amounts to total revenue over a specified period. Historical loss rates are adjusted due to the impact of current conditions, as well as forecasted conditions over a reasonable time period. The calculated write-off rate can be applied to the receivable balance for which an established reserve does not already exist. Management reviews the assumptions and risk of loss periodically for trade and other receivables.
14. STOCKHOLDERS' EQUITY
Basic EPS is computed by dividing net income available to Duke Energy common stockholders, as adjusted for distributed and undistributed earnings allocated to participating securities and accumulated preferred dividends, by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income available to Duke Energy common stockholders, as adjusted for distributed and undistributed earnings allocated to participating securities, 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.

Common Stock
In March 2026, Duke Energy filed a prospectus supplement and executed an Equity Distribution Agreement (EDA) under which it may sell up to $6 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 is entitled to issue and sell shares of common stock through September 2028.
The following table shows ATM equity issuances pursuant to forward contracts executed during the six months ended June 30, 2026.

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, 2027. 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.

16. INCOME TAXES
The IRA established transferability markets that enable monetization of tax credits. In April 2026, Duke Energy executed a multi-year agreement with a counterparty for the sale of up to $3.1 billion in net tax credits, including nuclear PTCs, solar PTCs and ITCs to be earned from 2025 through 2028. Proceeds are expected to be received from 2026 through 2029, including approximately $2 billion for Duke Energy Carolinas, $700 million for Duke Energy Progress and $350 million for Duke Energy Florida. The net realizable value from the sale of these tax credits is expected to ultimately flow back to customers through rates over time, subject to regulatory approval.
Corporate Alternative Minimum Tax
On February 18, 2026, the U.S. Treasury Department published Notice 2026-7 providing additional interim guidance on the application of the Corporate Alternative Minimum Tax (CAMT) under the Internal Revenue Code. The notice includes adjustments to the adjusted financial statement income that permit taxpayers to deduct certain tax-deductible repairs with respect to Section 168 property for CAMT purposes, as well as other adjustments related to capitalization differences.
As a result, Duke Energy intends to file amended federal tax returns with additional refund claims of approximately $70 million for tax years 2023 and 2024. Duke Energy also reduced accrued taxes by $80 million related to tax year 2025. These amounts have been recorded to the Duke Energy Condensed Consolidated Balance Sheets as of June 30, 2026, as well as a corresponding $150 million reduction to deferred income tax assets due to lower CAMT credit carryforwards.
EFFECTIVE TAX RATES
The ETRs from continuing operations for each of the Duke Energy Registrants are included in the following table.

The increase in the ETR for Duke Energy for the three months ended June 30, 2026, was primarily due to a decrease in the amortization of EDIT and lower state tax expense in the prior year, partially offset by an increase in the amortization of nuclear PTCs.
The increase in the ETR for Duke Energy for the six months ended June 30, 2026, was primarily due to non-deductible goodwill associated with the sale of Piedmont's Tennessee business and a decrease in the amortization of EDIT, partially offset by an increase in the amortization of nuclear PTCs.

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 six months ended June 30, 2026, and with Duke Energy’s Annual Report on Form 10-K for the year ended December 31, 2025.
Executive Overview
During the six months ended June 30, 2026, we continued to execute our strategy of investing in infrastructure necessary to support customer growth while maintaining reliability and financial discipline. We completed two strategic transactions that generated approximately $5.3 billion of proceeds to support future infrastructure investments, advanced key regulatory initiatives, including the planned combination of our Carolinas' electric utilities, and maintained reliability as we met continued growth across our service territories. These developments support our long-term capital investment plan and position us to meet the increasing energy needs of our customers while creating long-term value for shareholders.
Executing on Strategic Transactions. Our service territories continue to experience significant growth driven by economic development activity, population growth and increasing customer demand, which are expected to support substantial capital investment opportunities in the coming years. We completed two previously announced strategic transactions that enhance our financial flexibility and support the funding of our long-term capital plan.
On March 3, 2026, we completed the first closing of a minority investment in Florida Progress, the holding company of Duke Energy Florida, by an affiliate of Brookfield Super-Core Infrastructure Partners. The initial investment resulted in the transfer of a 9.19% ownership interest for approximately $2.8 billion in cash proceeds, with additional staged investments anticipated through 2028. On March 31, 2026, following approval by the TPUC, we closed on the sale of Piedmont's Tennessee business to Spire, Inc. and received approximately $2.5 billion in cash proceeds.
The successful execution of these transactions supports our ability to fund the investments required to meet anticipated customer growth while maintaining financial flexibility through disciplined capital allocation. See Note 2 to the Condensed Consolidated Financial Statements, "Dispositions," for further information.
Constructive Regulatory Outcomes. During the six months ended June 30, 2026, we continued to advance key regulatory initiatives and the investments necessary to support growth, maintain reliable service and position our business for long-term success. These efforts remain focused on delivering safe and reliable electric and natural gas service, supporting customer affordability and achieving timely recovery of prudent costs.
•Revised base rates became effective during the first quarter of 2026 for Duke Energy Carolinas' and Duke Energy Progress' South Carolina service territories and Duke Energy Kentucky's natural gas business. During 2026, Duke Energy Ohio's electric and natural gas businesses and Piedmont's South Carolina natural gas business filed new base rate applications. In July, we reached settlements in Duke Energy Carolinas' 2025 North Carolina Rate Case and proceedings related to Winter Storm Fern. Our regulatory efforts remain focused on securing the recovery of investments necessary to maintain and strengthen our electric and natural gas systems while continuing to provide reliable service to customers.
•We received CECPCN approval from the PSCSC for a new combined-cycle generating unit in Anderson County, South Carolina, as well as out-of-state certificates for new combustion turbine facilities at Marshall Steam Station and new combined-cycle units in Person County, North Carolina. These projects are expected to play an important role in supporting growing customer demand and maintaining system reliability as we modernize our generation fleet. In May 2026, the PSCSC also issued an order accepting our latest Carolinas systemwide resource plan.
•Our nuclear fleet continues to provide a significant source of reliable, carbon-free and cost-competitive generation. In February 2026, we announced that our nuclear fleet achieved a record systemwide capacity factor in 2025. In April 2026, the NRC issued a subsequent license renewal for Robinson, extending operations through 2050. Also during April, we executed a multi-year agreement to sell up to $3.1 billion of net tax credits through 2029, including nuclear PTCs, in continued support of providing low-cost electricity to our customers.
•The FERC issued an order authorizing the proposed combination of our two electric utilities operating in the Carolinas, finding the transaction consistent with the public interest. The companies also reached comprehensive settlements with intervenors in North Carolina and South Carolina and received approvals from both the NCUC and the PSCSC. The targeted effective date of the combination remains January 1, 2027.
Economic Development. Customer growth across our service territories continues to be driven by population growth, economic development activity and increasing electrification. Demand associated with data center development remains a significant contributor to projected load growth.
99
| MD&A | DUKE ENERGY | ||||
We continue to expand our portfolio of data center electric service agreements, increasing contracted capacity while maintaining a disciplined approach to infrastructure investment. These arrangements include financial protections designed to support system reliability, facilitate continued investment and align the costs of serving new large-load customers with the customers driving those investments. As a result, these agreements help mitigate the potential for cost impacts to other customers while supporting continued growth opportunities across our jurisdictions.
These trends continue to support Duke Energy’s long‑term regulated capital plan while supporting reliable service and customer affordability.
Operational Excellence. The safe and reliable operation of our electric generation fleet, transmission and distribution systems and natural gas infrastructure remains fundamental to serving our customers and supporting our financial performance. Operational excellence is particularly important during significant weather events when system reliability and effective service restoration are critical.
In late January 2026, Winter Storm Fern impacted all of our service territories. Sustained subfreezing temperatures drove customer energy usage to record winter peak demand levels across the Carolinas. We implemented storm preparation and response measures, including pre‑positioning crews and equipment, coordinating mutual‑assistance resources and leveraging established restoration processes. These efforts supported continued system reliability and timely restoration activities where service interruptions occurred.
See Notes 4 and 16 to the Condensed Consolidated Financial Statements, "Regulatory Matters" and "Income Taxes," respectively, along with "Other Matters," for additional information.
Duke Energy Objectives and Beyond. For the remainder of 2026, we remain focused on executing our strategic priorities, including advancing key regulatory initiatives, supporting customer growth and investing in the infrastructure necessary to maintain safe and reliable service. The combination of constructive regulatory outcomes, continued economic development growth, disciplined capital allocation and strong operational execution positions us to support our customers and communities while creating long‑term shareholder value.
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.
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. In April 2026, the EPA proposed to rescind or modify certain aspects of the 2015 CCR Rule, as amended by the 2024 CCR Rule. Duke Energy is evaluating the proposed rule and its potential impact on the Company, which could be material.
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."
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. Compliance with EPA Rule 111, if implemented as issued, would have a material impact on 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 published a proposed rule to repeal EPA Rule 111 as well as an alternative proposal to repeal a narrower set of requirements. Duke Energy is evaluating these proposals and their potential impacts on the Company. 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 impacts on the prices or availability of goods resulting from global conflicts, geopolitical developments, restrictions on trade involving certain rare earth materials and technologies used in electric utility infrastructure or evolving trade and tariff policies. Public policy developments, including new or revised 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 or execution on the Company's energy modernization strategy.
Goodwill
The Duke Energy Registrants performed their annual goodwill impairment tests as of August 31, 2025. As of that date, the estimated fair values of all reporting units materially exceeded the carrying values except for the GU&I reporting unit of Duke Energy Ohio. No goodwill impairment charges were recorded in the accompanying Condensed Consolidated Statements of Operations. However, adverse changes in economic conditions, projected future cash flows or peer company equity valuations could reduce the estimated fair value of the GU&I reporting unit below its carrying amount and result in goodwill impairment charges in future periods.

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:
•Legal and Regulatory Settlements represent the impact of charges related to legal settlements as well as regulatory settlements related to the Duke Energy Carolinas' North Carolina rate case and establishment of a regulatory liability associated with an energy efficiency program at Duke Energy Carolinas and Duke Energy Progress.
•Asset Sales represent the impact of gains on sale of assets related to Piedmont's Tennessee business and certain renewable natural gas investments.
Discontinued Operations represents the resolution of an outstanding liability related to the Commercial Renewables Disposal Groups.
Three Months Ended June 30, 2026, as compared to June 30, 2025
GAAP reported EPS was $1.38 for the three months ended June 30, 2026, compared to $1.25 for the three months ended June 30, 2025. In addition to the drivers below, GAAP reported EPS includes the impact of charges related to North Carolina rate case settlements for the three months ended June 30, 2026.
As discussed above, management also evaluates financial performance based on adjusted EPS. Duke Energy’s adjusted EPS was $1.43 for the three months ended June 30, 2026, compared to $1.25 for the three months ended June 30, 2025. The increase in adjusted EPS was primarily due to the recovery of infrastructure investments to reliably serve customers in our growing jurisdictions, partially offset by higher depreciation on a growing asset base and interest expense.
The following table reconciles non-GAAP measures, including adjusted EPS, to their most directly comparable GAAP measures.

Six Months Ended June 30, 2026, as compared to June 30, 2025
GAAP Reported EPS was $3.35 for the six months ended June 30, 2026, compared to $3.00 for the six months ended June 30, 2025. In addition to the drivers below, GAAP reported EPS increased primarily due to the gain on sale of Piedmont's Tennessee business, offset by charges related to legal and regulatory settlements.
As discussed above, management also evaluates financial performance based on adjusted EPS. Duke Energy’s adjusted EPS was $3.36 for the six months ended June 30, 2026, compared to $3.00 for the six months ended June 30, 2025. The increase in adjusted EPS was primarily due to the recovery of infrastructure investments to reliably serve customers in our growing jurisdictions, partially offset by higher depreciation on a growing asset base, interest expense and operation and maintenance expense, including storm costs.

Three Months Ended June 30, 2026, as compared to June 30, 2025
EU&I’s results were primarily driven by higher revenues from rate cases across multiple jurisdictions and higher weather-normal retail sales volumes and lower operation and maintenance expenses, partially offset by higher depreciation expense, impairments and interest expense. The following is a detailed discussion of the variance drivers by line item.
Operating Revenues. The variance was driven primarily by:
•a $145 million increase in fuel revenues primarily due to net higher fuel rates and volumes in the current year;
•a $117 million increase due to higher pricing from rate cases across jurisdictions;
•an $84 million increase in weather-normal retail sales volumes;
•a $74 million increase in rider revenue primarily due to higher rates for the SPP at Duke Energy Florida and the Distribution Capital Investment Rider at Duke Energy Ohio; and
•a $52 million increase in wholesale revenues, net of fuel, due to higher capacity volumes and rates at Duke Energy Progress.
Partially offset by:
•a $278 million decrease in storm recovery revenues at Duke Energy Florida; and
•a $20 million decrease in retail sales due to less favorable weather in the current year.
Operating Expenses. The variance was driven primarily by:
•a $255 million decrease in operation, maintenance and other primarily due to lower storm amortization at Duke Energy Florida; and
•a $28 million decrease in property and other taxes due to franchise tax refunds, partially offset by a higher base on which property taxes are levied across jurisdictions.
103
| MD&A | SEGMENT RESULTS — ELECTRIC UTILITIES AND INFRASTRUCTURE | ||||
Partially offset by:
•a $112 million increase in depreciation and amortization primarily due to higher depreciable base across all jurisdictions and the impact of new rates implemented by jurisdictional rate cases and the prior year retirement of renewable energy credits at Duke Energy Progress;
•a $50 million increase in impairment of assets and other charges primarily due to regulatory settlements related to the 2025 North Carolina rate case; and
•a $35 million increase in fuel used in electric generation and purchased power primarily due to higher purchased power costs, partially offset by lower fuel cost recovery and the prior year retirement of renewable energy credits at Duke Energy Progress.
Interest Expense. The increase was primarily due to higher outstanding debt balances across jurisdictions, lower returns on deferred storm cost balances and higher accrued financing costs associated with deferred nuclear PTC liabilities at Duke Energy Carolinas.
Income Tax Expense. The increase in tax expense was primarily due to an increase in pretax income. The ETRs for the three months ended June 30, 2026, and 2025, were 14.7% and 14.1%, respectively.
Net Income Attributable to NCI. The increase was due to the first closing of a minority interest investment in Florida Progress by Brookfield Super-Core Infrastructure Partners.
Six Months Ended June 30, 2026, as compared to June 30, 2025
EU&I’s results were primarily driven by higher revenues from rate cases across multiple jurisdictions and higher weather-normal retail sales volumes, partially offset by higher depreciation and operation and maintenance expenses. The following is a detailed discussion of the variance drivers by line item.
Operating Revenues. The variance was driven primarily by:
•a $431 million increase in fuel revenues primarily due to net higher fuel rates and volumes in the current year;
•a $319 million increase due to higher pricing from rate cases across jurisdictions;
•a $117 million increase in weather-normal retail sales volumes;
•an $87 million increase in wholesale revenues, net of fuel, due to higher capacity volumes and rates at Duke Energy Progress;
•a $79 million increase in rider revenues primarily due to higher rates for the SPP at Duke Energy Florida and Distribution Capital Investment Rider at Duke Energy Ohio; and
•a $50 million increase in other revenues primarily due to higher transmission revenues across jurisdictions.
Partially offset by:
•a $261 million decrease in storm recovery revenues at Duke Energy Florida.
Operating Expenses. The variance was driven primarily by:
•a $356 million increase in fuel used in electric generation and purchased power primarily due to higher natural gas prices and higher purchased power costs, partially offset by lower fuel cost recovery and the prior year retirement of renewable energy credits at Duke Energy Carolinas and Duke Energy Progress;
•a $276 million increase in depreciation and amortization primarily due to higher depreciable base across jurisdictions, higher depreciation rates driven by rate cases and the prior year retirement of renewable energy credits at Duke Energy Carolinas and Duke Energy Progress;
•a $50 million increase in impairment of assets and other charges primarily due to regulatory settlements related to the 2025 North Carolina rate case; and
•a $30 million increase in operation, maintenance and other primarily due to increased costs related to a legal settlement, higher storm costs in the current year associated with Winter Storm Fern, higher nuclear outage costs and higher costs related to customer products and services programs at Duke Energy Progress and Duke Energy Carolinas, partially offset by lower storm amortization at Duke Energy Florida.
Interest Expense. The increase was primarily due to higher outstanding debt balances across jurisdictions, lower returns on deferred storm cost balances and higher accrued financing costs associated with deferred nuclear PTC liabilities at Duke Energy Carolinas.
Income Tax Expense. The decrease in tax expense was primarily due to an increase in the amortization of nuclear PTCs, partially offset by a decrease in the amortization of EDIT. The ETRs for the six months ended June 30, 2026, and 2025, were 12.0% and 13.4%, respectively. The decrease in the ETR was primarily due to an increase in the amortization of nuclear PTCs, partially offset by a decrease in the amortization of EDIT.
Net Income Attributable to NCI. The increase was due to the first closing of a minority interest investment in Florida Progress by Brookfield Super-Core Infrastructure Partners.

Three Months Ended June 30, 2026, as compared to June 30, 2025
GU&I’s results were primarily driven by lower franchise taxes, offset by lower operating results due to the sale of Piedmont's Tennessee business. The following is a detailed discussion of the variance drivers by line item.
Operating Revenues. The variance was driven primarily by:
•a $28 million decrease in cost of natural gas revenues primarily due to lower commodity prices; and
•a $24 million decrease due to lower revenues as a result of the sale of Piedmont's Tennessee business.
Partially offset by:
•an $8 million increase due to higher capital riders.
Operating Expenses. The variance was driven primarily by:
•a $28 million decrease in cost of natural gas revenues primarily due to lower commodity prices; and
•a $13 million decrease in property and other taxes primarily due to lower franchise taxes.
Income Tax Expense (Benefit). The increase in tax expense was primarily due to an increase in pretax income and lower state tax expense in the prior year. The ETRs for the three months ended June 30, 2026, and 2025, were 23.1% and (200)%, respectively. The increase in the ETR was primarily due to lower state tax expense in the prior year.

Six Months Ended June 30, 2026, as compared to June 30, 2025
Operating Revenues. The variance was driven primarily by:
•a $105 million increase in cost of natural gas revenues primarily due to higher commodity prices;
•an $8 million increase due to the North Carolina IMR; and
•an $8 million increase due to the South Carolina Rate Stabilization Act.
Partially offset by:
•a $24 million decrease due to lower revenues as a result of the sale of Piedmont's Tennessee business.
Operating Expenses. The variance was driven primarily by:
•a $105 million increase in cost of natural gas due to higher commodity prices.
Partially offset by:
•a $16 million decrease in operations, maintenance and other primarily due to lower expenses as a result of the sale of Piedmont's Tennessee business and lower shared services costs.
Gains (Losses) on Sales of Other Assets and Other, net. The increase was due to the gain on sale of Piedmont's Tennessee business.
Income Tax Expense. The increase in tax expense was primarily due to an increase in pretax income and higher state tax expense associated with the sale of Piedmont's Tennessee business.
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. Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida are also monetizing tax credits in the transferability markets established by the IRA and are working with utility commissions on the appropriate regulatory process to pass the net realizable value back to customers over time. In April 2026, we executed a multi-year agreement to sell up to $3.1 billion of net tax credits with expected proceeds to be received through 2029. See Note 16 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, 2025, included a summary and detailed discussion of projected primary sources and uses of cash for 2026 to 2028.
Duke Energy has 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, 2027. See Note 14 to the Condensed Consolidated Financial Statements, “Stockholders’ Equity” for further details.
In March 2026, Duke Energy extended the termination date of its existing $10 billion Master Credit Facility to March 2031. As of June 30, 2026, Duke Energy had $673 million of cash on hand and $8.0 billion available under its Master Credit Facility. Duke Energy expects to have sufficient liquidity in the form of cash on hand, cash from operations and available credit capacity to support its funding needs.
In July 2025, Piedmont entered into a purchase agreement with Spire Inc., to sell Piedmont’s Tennessee business. On March 31, 2026, Piedmont closed on the sale and received proceeds of approximately $2.5 billion. 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 an eventual anticipated 19.7% indirect investment in Duke Energy Florida following a series of closings through June 30, 2028. On March 3, 2026, Duke Energy, Progress Energy and Florida Progress consummated the first closing that resulted in Florida Progress issuing 9.19% of its membership interests in exchange for approximately $2.8 billion in cash proceeds. See Note 2 to the Condensed Consolidated Financial Statements, "Dispositions," for further details.

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, 2025, 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. Compliance with EPA Rule 111 as issued would have a material impact on the timing, nature and magnitude of future generation investments in our service territories. 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 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. 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. The Duke Energy Registrants will continue to monitor rule-making developments and actions of the court and will evaluate the impacts of any final rule and other EPA actions, once available.
Coal Combustion Residuals
In April 2024, the EPA issued the 2024 CCR Rule, which significantly expanded the scope of the 2015 CCR Rule by establishing regulatory requirements for inactive surface impoundments at retired generating facilities (Legacy CCR Surface Impoundments). The 2024 CCR Rule also imposed a subset of the 2015 CCR Rule's requirements, including groundwater monitoring, corrective action (where necessary), and in certain cases, closure, and post-closure care requirements, on previously unregulated coal ash surfaces at regulated facilities (CCR Management Units). 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 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. On December 15, 2025, the EPA filed a motion with the Court requesting a continuing abeyance while it reconsiders certain aspects of the 2024 CCR Rule for both Legacy CCR Surface Impoundments and CCR Management Units. On December 16, 2025, the Court granted the EPA’s motion and ordered that the litigation continue to remain in abeyance pending further order of the Court.
116
| MD&A | OTHER MATTERS | ||||
On April 13, 2026, the EPA published in the Federal Register a proposed rule titled “Hazardous and Solid Waste Management System: Disposal of Coal Combustion Residuals from Electric Utilities; Legacy/CCRMU Amendments” under which the EPA proposes numerous amendments to the 2015 CCR Rule, as amended by the 2024 CCR Rule. Among other changes, the EPA is proposing to rescind all CCR Management Unit requirements finalized in the 2024 CCR Rule. In the event the EPA determines not to rescind all such requirements, the EPA is also seeking comments on several potential alternatives that would revise the existing CCR Management Unit regulations, including (i) deferring all CCR Management Unit requirements (other than the requirement to complete facility evaluations) to determinations made by a regulatory authority under a state or federal CCR permit program and (ii) expanding the CCR permit program deferral criteria for certain CCR Management Unit closures to a state or federal permit authority. With respect to Legacy CCR Surface Impoundments, the EPA is proposing (i) to establish an additional pathway for owners and operators of such units to certify closure by removal of the unit under the oversight of a regulatory authority prior to November 8, 2024, and (ii) to expand the CCR permit program deferral criteria for Legacy CCR Surface Impoundments that completed closure under state or federal regulatory authority prior to November 8, 2024, until the CCR permit authority can consider, on a site-specific basis, the need for additional closure measures, if any, to be taken. The Duke Energy Registrants will continue to monitor rule-making developments and actions of the court and will evaluate the impacts of any final rule and other EPA actions, once available. A final rule is anticipated in the fourth quarter of 2026.
In addition to the requirements of the federal CCR rules, CCR landfills and surface impoundments will continue to be regulated by the states. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions and via wholesale contracts, which permit recovery of reasonable and prudently incurred costs associated with Duke Energy’s regulated operations.
State Legislation
Indiana House Enrolled Act 1002
Indiana House Enrolled Act 1002 was signed into law on February 26, 2026. It reflects legislative priorities focused on electric utility affordability, low-income customer protections and assistance, and longer-term ratemaking concepts, including three-year rate plans and performance-based affordability and reliability metrics. Under the law, Duke Energy Indiana is required to file its first MYRP between November 15 and December 15, 2026.
Ohio Natural Gas Senate Bill 103
Ohio Senate Bill 103 (SB103) was signed into law and became effective on March 20, 2026. SB103 allows natural gas utilities to file MYRPs with forward-looking test periods.
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 that builds upon the approved dual-state 2023 Carolinas Resource Plan. The 2025 Plan seeks to maximize the value of existing resources, enhance grid flexibility and add new supply-side resources to reliably meet growing energy demands in the most reasonable and cost-effective manner in a period of unprecedented load growth. The evidentiary hearing took place in June 2026 and an order from the NCUC is expected to be issued by December 31, 2026. Information related to the updated systemwide plan was filed with the PSCSC on November 25, 2025, and the PSCSC issued an order accepting the resource plan on May 15, 2026.

ITEM 1. LEGAL PROCEEDINGS
The litigation matter of NTE Carolinas II, LLC Litigation included in Part 1, Item 1 of this Quarterly Report on Form 10-Q, within Note 5, "Commitments and Contingencies" of the Condensed Consolidated Financial Statements, is incorporated herein by reference.
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 (the State) 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. The State seeks an unspecified amount of monetary damages. MTBE is a gasoline additive intended to increase the oxygen content in gasoline and promote cleaner combustion. The case was removed from Baltimore City Circuit Court to federal district court. In December 2020, the State and the defendants selected 50 focus sites, none of which have any ties to Duke Energy Merchants. In November 2025, Duke Energy Merchants entered into a settlement agreement with the State that provided for the payment of an immaterial amount to settle the claims against Duke Energy Merchants. Certain non-settling defendants opposed the settlement, and the court subsequently withdrew its prior dismissal orders. Following a hearing and competing proposed orders, the court referred the matter to a magistrate judge for mediation which occurred on July 29, 2026. The parties continue to engage in discussions regarding potential resolution and the matter remains pending.
Other Proceedings
In addition, the Duke Energy Registrants are, from time to time, parties to various lawsuits and regulatory proceedings in the ordinary course of their business. For information regarding legal proceedings, including regulatory and environmental matters, see Note 4, "Regulatory Matters," and Note 5, "Commitments and Contingencies," to the Condensed Consolidated Financial Statements.
