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 three months ended March 31, 2025, and with Duke Energy’s Annual Report on Form 10-K for the year ended December 31, 2024.

Executive Overview

Advancing Regulatory Initiatives and Energy Modernization. During the three months ended March 31, 2025, we continued to move our regulatory strategy forward and execute on investments for energy modernization while maintaining our focus on safety and operational excellence, our customers, growth of our business as well as the engagement and empowerment of our employees. These priorities enable us to provide strong, sustainable value for our employees, customers, communities and shareholders.

• In January 2025, Piedmont and Duke Energy Indiana received constructive orders on their general rate cases from the NCUC and IURC, respectively. New rates were effective in November 2024 for Piedmont and late February 2025 for Duke Energy Indiana. Additionally, new rates were effective in January 2025 for Duke Energy Florida's new three-year rate plan.

• In February 2025, Duke Energy Progress filed an application to construct and operate a second hydrogen-capable advanced-class CC unit in Person County at the Roxboro Plant in North Carolina and Duke Energy Indiana filed for a CPCN for the Cayuga CC Project. In March 2025, a final air permit was issued for the Cayuga CC Project. These advanced natural gas plants, along with our planned CTs at the existing Duke Energy Carolinas' Marshall Steam Station, will provide critical generation as we continue to modernize our energy infrastructure in the coming years.

• We reached key milestones to recover costs related to critical storm restoration activities from the 2024 historic storm season while also seeking to minimize customer bill impacts resulting from hurricanes Debby, Helene and Milton. In February 2025, the FPSC voted to approve Duke Energy Florida's storm cost recovery of approximately $1.1 billion over 12 months beginning in March 2025. In March 2025, Duke Energy Carolinas filed a petition for storm securitization with the PSCSC for authorization to finance the estimated South Carolina-retail allocable share of storm costs. In April 2025, Duke Energy Carolinas and Duke Energy Progress received a constructive order from the NCUC on Phase I proceedings in North Carolina related to storm securitization and reached a settlement with the North Carolina Public Staff to resolve all remaining issues in Phase 2 in advance of the evidentiary hearing. A Phase 2 order is expected in June 2025.

• Our nuclear sites continue to benefit our customers and communities by reliably generating large amounts of electricity with low operating costs, providing thousands of well-paying jobs and producing economic and tax benefits for our local communities. In March 2025, the NRC issued the subsequent renewed licenses for Oconee, allowing an additional 20 years of operation of the units through 2053 and 2054. Oconee is the first of Duke Energy's nuclear facilities to reach this significant milestone and receive approval to operate for 80 years. In April 2025, we submitted a subsequent license renewal application to the NRC for Robinson, which would extend the plant's operations an additional 20 years through 2050. We've also continued to sell nuclear PTCs in 2025 as allowed under the IRA, working to further lower the cost of the energy modernization for our customers.

See Notes 4 and 16 to the Condensed Consolidated Financial Statements, "Regulatory Matters" and "Income Taxes," for additional information.

Matters Impacting Future Results

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

Regulatory Matters

Coal Ash Costs

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

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

Storm Cost Recovery

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

EPA Regulations of GHG Emissions

In April 2024, the EPA issued final rules under section 111 of the Clean Air Act (EPA Rule 111) regulating GHG emissions from existing coal-fired and new natural gas-fired power plants. Duke Energy is analyzing the potential impacts the rules could have on the Company, which could be material and may influence the timing, nature and magnitude of future generation investments in our service territories. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of reasonable and prudently incurred costs associated with Duke Energy’s regulated operations. Duke Energy is participating in legal challenges to the final rules. For more information, see "Other Matters."

Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed by the Duke Energy Registrants in the reports they file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified by the SEC rules and forms.

Disclosure controls and procedures include, without limitation, controls and procedures designed to provide reasonable assurance that information required to be disclosed by the Duke Energy Registrants in the reports they file or submit under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, the Duke Energy Registrants have evaluated the effectiveness of their disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2025, and, based on this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these controls and procedures are effective in providing reasonable assurance of compliance.

Changes in Internal Control over Financial Reporting

Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, the Duke Energy Registrants have evaluated changes in internal control over financial reporting (as such term is defined in Rules 13a-15 and 15d-15 under the Exchange Act) that occurred during the fiscal quarter ended March 31, 2025, and have concluded no change has materially affected, or is reasonably likely to materially affect, internal controls over financial reporting.

ITEM 1. LEGAL PROCEEDINGS

The Duke Energy Registrants are, from time to time, parties to various lawsuits and regulatory proceedings in the ordinary course of their business. For information regarding legal proceedings, including regulatory and environmental matters, see Note 4, "Regulatory Matters," and Note 5, "Commitments and Contingencies," to the Condensed Consolidated Financial Statements. For additional information, see Item 3, "Legal Proceedings," in Duke Energy's Annual Report on Form 10-K for the year ended December 31, 2024.

The Town of Carrboro Litigation

On December 4, 2024, the town of Carrboro, North Carolina, filed a lawsuit against Duke Energy in the North Carolina Superior Court, Orange County, alleging that Duke Energy and its predecessor companies knew since the late 1960s that fossil-fuel emissions could cause global climate changes and engaged in a campaign to conceal the dangers of fossil fuel emissions from the public, regulators, legislators, and others, resulting in a delayed transition away from fossil fuel emissions and worsening climate change. The lawsuit also alleges that Duke Energy misled the public regarding Duke Energy’s support for, and actions toward, transitioning its fossil fuel portfolio to renewable energy. The damages alleged range from road and stormwater-system impacts to increased electricity costs and recurring invasions and interferences from extreme weather events. The lawsuit asserts state law claims for public nuisance, private nuisance, trespass, negligence, and gross negligence, and is seeking an unspecified amount of monetary damages. The case has been transferred to the North Carolina Business Court. On March 17, 2025, Duke Energy filed a motion to dismiss the litigation based on lack of subject matter jurisdiction. In addition, Duke Energy's motion to dismiss based on failure to state a claim on which relief can be granted is due by May 9, 2025. Duke Energy cannot predict the outcome of this matter.

In addition to the other information set forth in this report, careful consideration should be given to the factors discussed in Part I, “Item 1A. Risk Factors” in Duke Energy's Annual Report on Form 10-K for the year ended December 31, 2024, which could materially affect the Duke Energy Registrants’ financial condition or future results.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

None.

Director and Officer Trading Arrangements

During the three months ended March 31, 2025, no director or officer of the Company adopted, terminated or modified a Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement, as each term is defined in Item 408(a) of Regulation S-K.
