•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.

Current report

On April 30, 2025, Ohio Substitute House Bill 15 (HB 15) was passed and sent to the governor of Ohio. Duke Energy Ohio anticipates HB 15 will become law by August 10, 2025. HB 15 eliminates Duke Energy Ohio's Legacy Generation Rider (LGR) upon the effective date of HB 15 and prevents the PUCO from future reauthorization of similar arrangements. As a result of HB 15, any future losses related to Duke Energy Ohio's Inter-Company Power Agreement with OVEC will not be recoverable from retail customers. Regulatory assets related to OVEC at the time of HB 15 becoming effective also may not be recoverable. Therefore, future losses related to Duke Energy Ohio's Inter-Company Power Agreement with OVEC would no longer be deferred or recovered from customers and will negatively impact Duke Energy Ohio’sresults of operations, financial position and cash flows. For more information, see Note 4 to the Condensed Consolidated Financial Statements, "Regulatory Matters."

Previous report

Operational Excellence, Safety and Reliability. The reliable and safe operation of our power generating facilities, electric distribution system and natural gas infrastructure in our communities continues to be foundational to serving our customers, our financial results, and our credibility with stakeholders. In recent months, we have responded to several unprecedented and catastrophic weather events across our service territories.

Previous report

In August 2024, Hurricane Debby made landfall in Florida as a Category 1 storm, impacting the Duke Energy Florida territory as well as the Duke Energy Carolinas and Duke Energy Progress territories in North Carolina and South Carolina and causing approximately 700,000 customer outages. In late September 2024, Hurricane Helene made landfall in Florida as a Category 4 storm and subsequently impacted all of Duke Energy's service territories as the storm moved inland, with the most severe damage occurring in Florida and the Carolinas. Approximately 3.5 million customers were impacted by Hurricane Helene across Duke Energy's system, the largest number of companywide outages from a single event on our system ever reported. Then, in October 2024, Hurricane Milton made landfall in Florida as a Category 3 storm, causing severe damage across our Florida service territory as a result of high winds, rain and flooding and resulting in more than 1 million customer outages.

Previous report

In such extreme circumstances, our immediate priority is, and always will be, executing the extensive storm preparation and response work to ensure the safe, timely, and efficient restoration of service to impacted customers as quickly as possible. Round-the-clock power restoration efforts continued following the historic damage inflicted by these storms with lineworkers, tree trimmers and removal experts, state department of transportation workers and countless others, working to repair and, in certain areas, completely rebuild, the critical electricity infrastructure that powers and supports the communities we serve. We've also seen the benefits of ongoing grid hardening investments, leveraging self-healing technologies and remote restoration capabilities to automate the rerouting of power, more effectively deploy resources, and reduce the frequency or duration of outages for many of our customers during severe weather events.

Previous report

We will continue the important work of rebuilding our communities in the weeks and months ahead, including power infrastructure in the hardest-hit areas of our service territories. We also plan to work with our state commissions to appropriately track and recover storm costs under approved regulatory frameworks on a timely basis. We will also remain focused on balancing the bill impacts on our customers from such catastrophic events, including seeking insurance recovery and exploring the potential securitization of related costs in certain jurisdictions, as appropriate. For more information, see "Matters Impacting Future Results," "Liquidity and Capital Resources," and Notes 4 and 6 to the Condensed Consolidated Financial Statements, "Regulatory Matters" and "Debt and Credit Facilities."

Previous report

Advancing Our Clean Energy Transition. During the nine months ended September 30, 2024, we continued to execute on our clean energy transition, remaining focused on reliability and affordability while delivering increasingly clean energy and providing strong, sustainable value for shareholders, customers, communities and employees.

Previous report

•In May 2024, we entered into memorandums of understanding with several large customers, which propose exploring new and innovative approaches to support carbon-free energy generation and serve future energy needs of large businesses in North Carolina and South Carolina through the use of new tariff structures. The proposed Accelerating Clean Energy (ACE) tariff framework includes new, voluntary pricing structures for large commercial and industrial customers, which enable their direct support of carbon-free energy generation investments including facilitating beneficial customer on-site generation and load flexibility programs. The proposed ACE tariffs would be subject to regulatory approvals and include protections for non-participating customers.

Previous report

•In January 2024, we filed supplemental modeling and analysis with the NCUC and PSCSC related to our combined systemwide Carolinas Resource Plan filed in August 2023. These updates were necessary due to substantially increased load forecasts resulting from continued economic development successes in the Carolinas occurring since the systemwide integrated resource plan was prepared. In March 2024, we filed for: (i) CPCNs with the NCUC for new natural gas generation facilities at the sites of the current Marshall Steam Station and Roxboro Plant in the Carolinas; and (ii) a Certificate of Environmental Compatibility and Public Convenience and Necessity with the PSCSC for a new solar center and associated facilities in Chesterfield and Darlington counties, South Carolina. Our energy transition strategy continues to focus on delivering a path to cleaner energy in a manner that protects grid reliability and affordability, all while meeting the energy demands of the growing and economically vibrant communities that we serve.

Previous report

•As we continue to strengthen our grid and bring clean energy resources online, our customers are important partners in our clean energy future. In January 2024, we received approval for PowerPair SM, a new incentive-based pilot program for installing home solar generation with battery energy storage in our Duke Energy Carolinas and Duke Energy Progress North Carolina service territories. Enrollment options for residential customers that participate in the pilot include a one-time incentive of up to $9,000 for the installation of a solar plus battery system. The program was launched in May 2024 and successfully enrolled more than 1,300 customers in its first three months, providing another impactful way for our customers to save energy and money, while exploring new solutions to help manage low carbon grids of the future.

Previous report

•In January 2024, Duke Energy Carolinas filed a South Carolina rate case, the first base rate case filed by Duke Energy Carolinas in the state since 2018 and reflecting the South Carolina retail allocation of significant investments, including approximately $1.5 billion of transmission and distribution assets. In May 2024, we reached a constructive comprehensive settlement with certain parties and in July 2024, the PSCSC issued an order approving the settlement and revising recovery of certain environmental compliance costs. New rates were effective August 1, 2024.

Previous report

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

Previous report

•Duke Energy Florida filed a three-year rate plan that will begin in January 2025, once its current base rate settlement agreement concludes at the end of 2024, andproposed approximately $4.9 billion in incremental investments to reduce outages, expand solar generation, and increase generation unit efficiency. In August 2024, the FPSC approved our constructive comprehensive settlement with certain parties, allowing us to continue making important investments to reduce outages, shorten response times, meet future energy demands, increase clean, solar generation and explore innovative technologies to generate cost savings for our customers.

Previous report

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

Previous report

•Piedmont filed a general rate case with the NCUC, its first base rate case in North Carolina since 2021, reflecting significant investments to support ongoing service reliability, system growth, and compliance with federal pipeline safety regulations in addition to two energy reliability centers in eastern North Carolina. In September 2024, we reached a constructive comprehensive settlement with certain parties. Revised interim rates were effective November 1, 2024, subject to refund and pending NCUC approval of the settlement and a final order.

Previous report

•Also, in April 2024, Duke Energy Progress issued $177 million of storm recovery bonds, our first issuance under South Carolina's 2022 securitization legislation, which provided the necessary framework for us to lower the bill impacts on our customers related to critical storm restoration activities.

Previous report

As a result of rapidly rising commodity costs during 2022, including natural gas, fuel and purchased power prices in excess of amounts included in fuel-related revenues led to an increase in the under collection of fuel costs from customers in jurisdictions including those served by Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida. These amounts have been deferred in regulatory assets and impacted the cash flows of the registrants, including increased borrowings to temporarily finance related expenditures until recovery. Regulatory filings have been made and approved for recovery of all remaining uncollected 2022 fuel costs. Across all jurisdictions, Duke Energy is currently on pace to recover approximately $1.8 billion of deferred fuel costs in 2024 and we anticipate being in line with our historical average balance of deferred fuel costs by the end of this year.

Previous report

•Regulatory Matters primarily represents impairment charges related to Duke Energy Carolinas' South Carolina rate case order in 2024 and the Duke Energy North Carolina rate case settlement and Duke Energy Progress' North Carolina rate case order in 2023.
