## Welcome to the Duke Energy

## Annual Meeting of Shareholders

#### March 20, 2026

#### Dear Fellow Shareholders:
I am pleased to invite you to Duke Energy's Annual Meeting to be held on Thursday, May 7, 2026, at 1 p.m. Eastern time. We look forward to updating you on our accomplishments in 2025, focus areas for 2026, and the path forward for Duke Energy.

2025 was a year of strong execution, grounded in our responsibility to deliver safe, reliable, and affordable energy. We met our financial objectives while continuing to invest in the infrastructure capabilities needed to support our customers' evolving needs. We are fortunate to operate in some of the most attractive jurisdictions in the country and are seeing sharp increases in energy demand driven by economic development, including data centers and advanced manufacturing, as well as continued population growth. To serve this demand responsibly, we executed electric service agreements for multiple hyperscale data centers representing cumulative contracted load of over 4.5 gigawatts, ensuring these customers contribute appropriately to the systems required to serve them.

On the generation side, we made significant progress to ensure reliability for all customers as demand continues to grow. This included subsequent license renewals (SLR) at Oconee Nuclear Station and SLR application for Robinson Nuclear Plant. We began construction on over 5 gigawatts of new natural gas generation in the Carolinas and Indiana, and submitted an early site permit application for potential new nuclear development at Belews Creek in North Carolina. Duke Energy Florida unveiled its DeBary Hydrogen Production Storage System, the first demonstration project in the United States capable of using an end-to-end system to produce, store and combust up to 100% green hydrogen. These actions reflect our focus on maintaining dependable service while responsibly advancing innovation.

In 2026, Duke Energy will continue to meet current and future energy needs by maximizing our existing resources, building new generation and continually optimizing our electric grid to improve resiliency and customer service. As load growth materializes across our territories, we're executing on our more than $103 billion, five-year capital plan – the largest regulated capital plan in the industry. By 2030, we plan to increase generation capacity by approximately 14 gigawatts – enough energy to power nearly 10 million homes. Throughout this period, Duke Energy remains committed to keeping power reliable and costs as low as possible, now and into the future. Our regulatory model has proved effective, and we have been successful in keeping average rate increases below inflation. We will continue to deliver long-term value to the vibrant communities we are honored to serve.

We are well positioned to serve our customers reliably and affordably through this period of dynamic growth. Duke Energy brings the expertise, scale, and proven track record of working constructively with our regulators, customers, communities and other stakeholders to execute our plans responsibly – while delivering value for both our customers and shareholders.

This proxy statement contains information about our Board's oversight of Duke Energy's strategy, performance, and risks, as well as our governance practices and our commitment to our employees, whose dedication directly contributes to our high customer satisfaction and continued operational excellence. It also describes the outreach we conducted in 2025 with you – our fellow shareholders – and how that feedback has informed our decisions and priorities.

#### Annual Meeting Details
This year's Annual Meeting will once again be held exclusively via live webcast. The online format has successfully expanded our ability to connect with shareholders from all over the world while still providing you the same opportunities to vote and ask questions that you would have had at an in-person meeting, including by submitting questions in writing in advance of the Annual Meeting on our pre-meeting forum at *www.proxyvote.com*. An audio broadcast of the Annual Meeting will also be available by phone toll-free at 877.328.2502. Details regarding how to participate in the Annual Meeting via live webcast, as well as the items to be voted on, are described in the accompanying Notice of Annual Meeting of Shareholders, "Rules of Conduct for the Annual Meeting," on page [1](#tROCF) of this proxy statement, and in the "Frequently Asked Questions and Answers About the Annual Meeting" on page [83](#tFAQA) of this proxy statement.

Please review this proxy statement prior to voting as it contains important information relating to the business of the Annual Meeting. Page [84](#tVVOTE) of this proxy statement contains instructions on how you can vote your shares online, by phone, or by mail. We encourage you to vote and share your feedback with us and hope you can participate in the Annual Meeting.

## Letter from the Board of Directors
**Dear Fellow Shareholders**:

As Duke Energy's independent directors, we are honored to share how the Board is working to ensure sound governance, effective leadership, and sustained value creation for our shareholders. Thank you for the trust you place in us.

#### Leadership Transition and Board Oversight
2025 was a pivotal year for Duke Energy as we successfully executed our leadership succession plan, electing Harry K. Sideris as President and CEO and as a member of our Board, effective April 1, 2025. In connection with the leadership transition, Theodore F. Craver, Jr. also transitioned from Lead Independent Director to Independent Chair of the Board, effective April 1, 2025. As President and CEO, Mr. Sideris brings decades of operational leadership across our utility businesses to sustain the Company's strong momentum – delivering financial results that exceeded earnings expectations in 2025, while advancing our long-term energy modernization strategy to strengthen the grid and meet growing customer needs.

#### Board Refreshment and Stakeholder Engagement
Board refreshment, Board diversity, and meaningful Board succession planning remain key areas of focus for our Board. Our current Board is a diverse, distinguished group of professionals with a wide range of experiences, skills, and qualifications. As part of our ongoing refreshment efforts, we were pleased to welcome Jeffrey B. Guldner to the Board during the year, bringing additional leadership and industry experience. Marie McKee, however, will be retiring from the Board and will not stand for re-election at the upcoming Annual Meeting. Ms. McKee has served with distinction since 2012, and the rest of the Board extends its sincere appreciation for her 14 years of dedicated service and contributions to Duke Energy. We have undertaken significant Board refreshment efforts in recent years with half of our current nominees for director having joined the Board in the last five years. We also continued our robust annual shareholder engagement program during the spring and fall, meeting with shareholders holding approximately 44% of our outstanding shares of common stock, as well as other stakeholder groups. We held numerous conversations with shareholders and stakeholders outside of our shareholder engagement program, and the feedback we have gathered from these engagements has helped the Board shape our policies, practices, and disclosures.

#### Strategic Priorities and Long-Term Value
As the energy industry continues to evolve and as we project significant load growth in our service territories over the coming years, our Company remains committed to modernizing critical infrastructure and investing in innovative technologies to enhance reliability, resiliency, and customer value. At each Board meeting and during our ongoing strategy sessions, we contribute to the Company's strategic plan by engaging senior leaders in robust discussions about business strategy, priorities, and risks and opportunities as we look to position Duke Energy as a leader in the evolving energy landscape, while delivering sustainable long-term value for our shareholders, customers, and employees.

Thank you for your continued support of our Company. We look forward to continuing our dialogue with shareholders at the 2026 Annual Meeting and throughout the year.

Sincerely,

PROXY SUMMARY

### 2025 Business Highlights
In 2025, we successfully continued along our path for sustainable long-term growth. We worked collaboratively with stakeholders across our service territories to advance our strategy of transforming for the future – all built on our Company values and employee imperatives. Our business highlights in 2025 include the following:

#### Financial Performance
• We delivered adjusted and reported EPS of $6.31 – above our earnings guidance midpoint for the year.

• We announced Tennessee and Florida transactions at premium valuations to strengthen our credit profile and efficiently finance our capital plan.

• We raised our long-term FFO/Debt target to 15% and achieved 14.8% in 2025.

• We worked with regulators and other stakeholders to recover and securitize nearly $3 billion worth of storm costs, approximately one year after major 2024 hurricanes,

• 2025 marked the 99<sup>th</sup> consecutive year we continued our dividend commitment to our shareholders.

#### Advancing New Generation
• We began construction on 5 gigawatts of new natural gas generation in the Carolinas and Indiana, and put in place

contracts to secure the long-lead time equipment and workforce needed to support this new dispatchable generation.

• We placed more than 300 megawatts of solar and 175 megawatts of storage into service across the Carolinas and Florida to continue to diversify generation mix.

• We received NRC approval for our SLR application for Oconee Nuclear Station, and filed SLR for Robison Nuclear Plant.

#### Delivering Value for Customers
• We filed to combine our Duke Energy Carolinas and Duke Energy Progress utilities, which if approved, would generate more than $1 billion in customer savings over time.

• We pursued federal energy tax credits, generating approximately $600 million in nuclear tax credits that will flow back to customers dollar-for-dollar over time.

• This was the 27<sup>th</sup> consecutive year of nuclear capacity factor exceeding 90%.

PROXY SUMMARY

### Shareholder Engagement Highlights
We have a long-standing history of engaging with, and responding to the feedback provided by, our shareholders and other stakeholders and value the deep relationships we have built. That feedback over time has greatly informed our compensation, stewardship, and governance programs. Given its success, we continued our shareholder outreach

program in 2025, reaching out to and engaging with holders of approximately 44% of Duke Energy's outstanding shares of common stock. We also sought to engage with every shareholder who requested to meet with us. These discussions included members of management and, in some instances, our President and CEO, or Independent Chair.

![[MISSING IMAGE: fc_spring-pn.jpg]](fc_spring-pn.jpg)

The agenda for these conversations spanned a variety of topics:

• ***Business and Strategy*** – As we are entering a period of heightened load growth, updates on our business performance and strategy, including financial results, growth targets, regulatory matters, strategic initiatives, capital expenditure plan alignment, anticipated energy generation mix through 2050, and exploration of new technologies, while keeping customer reliability and value top of mind;

• ***Regulatory and Jurisdictional Considerations*** – Review of relevant regulatory updates, including how we are balancing keeping rates as low as possible and reliability with decarbonization-oriented regulations and legislation;

• ***Risk Management* –** How we are reviewing the long-term exposure, risk, and vulnerability to physical impacts of extreme weather to our assets, including increasing the resilience of our energy system for the last decade through storm hardening, smart grid technologies, capacity, and reliability projects;

• ***Shareholder Proposals –*** Including any shareholder proposals received;

• ***Corporate Governance* –** Including our recent CEO transition, succession planning process, Board composition, refreshment, onboarding and education programs, self-assessment process and risk oversight role of the Board, including the use of artificial intelligence;

• ***Executive Compensation* –** Alignment of our executive compensation program with our strategic, financial, and operational objectives, including goals and metrics;

• ***Load Growth –*** Contract management and contingency plans for data centers coming onto our grid and how we are planning to serve the increased load demand; and

• ***Policy Impacts* –** Our policy priorities and engagement initiatives in support of our business strategy.

PROXY SUMMARY

### Duke Energy Actions and Disclosures in Response to Shareholder Feedback
Our Company values shareholder engagement. During the conversations we had in 2025, shareholders expressed appreciation for the pay for performance alignment in our compensation program, the clarity and detail in our executive compensation program disclosures, and that safety, customer satisfaction, and environmental metrics continue to be incorporated into our incentive plans. We greatly value the input shareholders provided and will continue our outreach efforts on a wide variety of topics.

In response to shareholder feedback reflecting a range of perspectives on climate related risks, assumptions, and long-term goals, in October 2025, we published our annual flagship voluntary disclosure, the 2024 Impact Report, available on our website at *www.duke-energy.com.* "Building A Smarter Energy Future" is Duke Energy's 19<sup>th</sup> annual report and outlines our approach to energy modernization and the vital role our vertically integrated utility plays in continuing to provide reliable energy at the lowest possible cost to customers, while supporting a growing economy and national security. We highlight our performance and progress on strategic business matters. It provides enhanced disclosure regarding our strategy, progress and the alignment of our policy engagement with our enterprise goals and complements our 2024 Climate Resilience & Adaptation Study and 2023 study focused on our transmission and distribution system in the Carolinas.

Our Company has also prepared numerous disclosures, which are located on our website at *www.duke-energy.com,* that are provided, in part, in response to shareholder and other stakeholder feedback on areas of interest, some of which include:

---

|:---|:---|

### PROPOSAL 1:

### ELECTION OF DIRECTORS

### The Board of Directors
The Corporate Governance Committee, comprised of only independent directors, has recommended all of the director nominees discussed on pages [14](#tBIOO) through [22](#tBDRV) of this proxy statement.

We have a declassified Board, which means all the directors are voted on every year at the Annual Meeting. If any director

is unable to stand for election, the Board may reduce the number of directors or designate a substitute. In that case, shares represented by proxies may be voted for a substitute director. We do not expect that any nominee will be unavailable or unable to serve.

Our Principles for Corporate Governance includes a director retirement policy, which is described in more detail on page [34](#tBODRE) of this proxy statement. Pursuant to this policy, Marie McKee will be retiring as of the 2026 Annual Meeting date.

Majority Voting for the Election of Directors

Under Duke Energy's By-Laws, in an uncontested election at which a quorum is present, a director-nominee will be elected if the number of votes cast "FOR" the nominee's election exceeds the number of votes cast "AGAINST" the nominee's election. Abstentions and broker non-votes do not count. In addition, Duke Energy has a resignation policy in our Principles for Corporate Governance, which requires that if an incumbent director has more votes cast as "AGAINST" that nominee's election than votes cast "FOR" his or her election,

such incumbent director must tender his or her letter of resignation for consideration by the Corporate Governance Committee.

In contested elections, directors will be elected by plurality vote. For purposes of the By-Laws, a "contested election" is an election in which the number of nominees for director is greater than the number of directors to be elected.

### INFORMATION ON THE BOARD OF DIRECTORS

### Our Board Leadership Structure
The Board regularly evaluates the leadership structure of Duke Energy and may consider alternative approaches, as appropriate, over time. The Board believes that Duke Energy and our shareholders are best served by the Board retaining discretion to determine the appropriate leadership structure based on what it believes is best for Duke Energy at a particular point in time, including whether the same individual should serve as both Chair and CEO, or whether the roles should be separate.

At this time, our Board believes that maintaining a separate CEO and Independent Chair of the Board structure is best for the Company, and gives primary responsibility for the operational leadership and strategic direction of Duke Energy to our CEO, while the Independent Chair of the Board facilitates our Board's independent oversight of management, serves as principal liaison between the Board and senior

management, and leads our Board's consideration of key governance matters.

The Board recognizes the importance of independent oversight over management at all times, and our Principles of Corporate Governance, a copy of which is posted on our website at *www.duke-energy.com/our-company/corporate-governance/principles-corp-governance,* provide that the independent members of the Board will elect a Lead Independent Director in the event the Chair of the Board and CEO roles are held by the same individual, or the person holding the role of Chair of the Board is not independent under Duke Energy's Standards for Assessing Director Independence, a copy of which is posted on our website at *www.duke-energy.com/our-company/corporate- governance/board*.

INFORMATION ON THE BOARD OF DIRECTORS

### Independence of Directors
The Board has determined that none of the director nominees, other than Mr. Sideris, has a material relationship with Duke Energy or any of our subsidiaries, and that all non-employee directors are, therefore, independent under the listing standards of the NYSE and the rules and regulations of the SEC.

In making the determination regarding each director's independence, the Board considered all transactions and the materiality of any relationship with Duke Energy and any of our subsidiaries in light of all facts and circumstances.

The Board may determine a director to be independent if it has affirmatively determined that the director has no material relationship with Duke Energy or our subsidiaries, either directly or as a shareholder, director, officer, or employee of an organization that has a relationship with Duke Energy or our subsidiaries. Independence determinations are generally made when a director joins the Board and on an annual basis at the time the Board approves director-nominees for inclusion in the proxy statement.

The Board also considers its Standards for Assessing Director Independence, which sets forth certain relationships between Duke Energy and our directors and their immediate family members, or affiliated entities, that the Board, in its judgment, has deemed to be immaterial for purposes of assessing a director's independence. Duke Energy's Standards for Assessing Director Independence are available on our website at *www.duke-energy.com/our-company/corporate-governance/board*. In the event a director has a relationship with Duke Energy that is not addressed in the Standards for Assessing Director Independence, the Corporate Governance Committee, which is composed entirely of independent members of the Board, reviews the relationship and makes a recommendation to the nonconflicted, independent members of the Board who determine whether such relationship is material.

### Director Attendance
The Board met eight times during 2025 and as of the date of this proxy statement, has met once so far in 2026. During the 2025 Board meetings, our Board held six executive sessions with independent directors only.

Directors are expected to attend at least 75% of Board meetings and the meetings of the committees upon which he or she serves. The overall attendance for our directors for Board and all committee meetings, including any special committee, was approximately 99% in 2025. All directors attended more than 75% of the Board meetings and the meetings of the committees upon which he or she served in 2025. Directors are also encouraged to attend the Annual Meeting. All directors who were directors at the time of last year's Annual Meeting on May 1, 2025, attended the 2025 Annual Meeting.

Board and Committee Assessments

Each year the directors, with the assistance of the Corporate Governance Committee, conduct a self-assessment of the Board, the committees, and the directors. The annual assessment process is conducted by a third-party, which allows directors to provide anonymous feedback and promotes candidness among the directors. The third-party aggregates and provides analysis of all results, which is then presented to the Board and committees and discussed in executive session.

In addition to the written assessments conducted annually by the third-party, the Independent Chair annually and throughout the year meets with each director individually to discuss the performance of the Board and to identify potential improvements to Board and director effectiveness.

Management and the Board then incorporate the feedback received in both the written assessments and the discussions throughout the year.

The annual review process and regular discussions throughout the year provide continuous improvement feedback in the overall effectiveness of the directors, committees, and Board, and provide an opportunity for directors to express any concerns they may have. This process also allows the Board to identify opportunities for Board refreshment, director education, and topics for the Board to focus on in future meetings.

During the Board's assessment in early 2025, the Board identified various topics for which they sought further education and briefings, additional metrics for regular review, and best practices they observed throughout the year. In response, the Company organized site visits for directors, including to a facility with research and development labs, classrooms, and training facilities where energy storage, drones, fleet and residential electrification, products and services, and other technologies are tested and developed. Additionally, we held director education sessions, featuring external speakers. These sessions covered a variety of topics, including industry and economic trends, advanced nuclear technologies, and quantum computing.

### Board Role in Management Succession
The independent directors of the Board are actively involved in our management succession planning process. Throughout the year, the independent directors discuss potential successors to key executives and examine backgrounds, capabilities and appropriate developmental assignments for potential successors. Among the Corporate Governance Committee's responsibilities described in its charter is the responsibility to oversee continuity and succession planning.

At least annually, the Corporate Governance Committee or full Board reviews the CEO succession plan and makes recommendations to the Board for the successor to the CEO. In addition, the Corporate Governance Committee reports to the Board regarding its assessment of how the Company is positioned to meet the requirements of Duke Energy's long-term goals.

Board Oversight of Risk

As is true with other large public companies, Duke Energy faces a myriad of risks, including operational, financial, strategic, and reputational risks that affect every segment of our business. The Board is actively involved in the oversight of these risks in several ways. This oversight is conducted primarily through the Finance and Risk Management Committee of the Board but also through the other committees of the Board, as appropriate. The Finance and Risk Management Committee reviews Duke Energy's enterprise risk program with management, including the Chief Risk Officer, on a regular basis at its committee meetings. The enterprise risk program, which is reviewed by the full Board annually, includes the identification of a broad range of risks that affect Duke Energy, their probabilities and severity, and incorporates a review of our approach to managing and prioritizing those risks based on input from the officers

responsible for the management of those risks. As part of this enterprise risk oversight, the Board and its committees consider, as applicable, emerging risks associated with the use of advanced and evolving technologies, including artificial intelligence, within Duke Energy's existing risk management framework.

In addition to the oversight of enterprise risk that is conducted through the Finance and Risk Management Committee, each committee of the Board is responsible for the oversight of certain risks that pertain to that committee's area of focus. Each committee regularly receives updates from the business units to review the risks in those areas. Throughout the year, each committee Chair reports to the full Board regarding the committee's considerations and actions related to the risks within its area of focus.

#### Board Oversight of Key Risks
Duke Energy's enterprise-wide risk management process is designed to identify, assess, prioritize, and mitigate risks that could negatively impact its business or strategic objectives. The Company's risk oversight processes and disclosure controls and procedures are designed to appropriately and timely escalate key risks to the Board, as well as to management and key employees in order to analyze potential risks for disclosure purposes.

#### Climate, regulatory and legislative, and supply chain risk
• The Finance and Risk Management Committee receives regular updates from management regarding the Company's top risks and mitigation efforts, which are reported to the Board. In 2025, these topics included discussions of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Financing our strategy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • The pace of our efforts to modernize the energy infrastructure relative to customer affordability and reliability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Diversification of critical suppliers and pre-committing to long-lead equipment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Impact of severe weather events; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Federal and state policy and regulations.

• The Compensation and People Development Committee incorporates an energy modernization goal into the Company's STI Plan, as further described on page [46](#tCPDCI) of this proxy statement. This goal further enhances the other performance measures in our compensation plans.

#### Talent, workforce, and charitable giving
• The Compensation and People Development Committee discusses, reviews, and oversees risks related to employee engagement trends, the design and operation of the incentive compensation programs and the degree to which such programs appropriately balance enterprise risk, workforce programs and metrics, plans to support our business strategy and future workforce needs.

• The Corporate Governance Committee regularly discusses charitable contributions and priority areas for giving. In fiscal year 2025, Duke Energy and the Duke Energy Foundation invested nearly $42.7 million to directly support our communities.

• The Operations and Nuclear Oversight Committee reviews the Company's operations, as well as environmental, health and safety performance at each regular committee meeting.

#### Governance – Cybersecurity and political expenditures and sustainability-focused disclosures oversight
• Senior leadership briefs the Board and Audit Committee on information security matters, including AI, several times throughout the year. In 2025, the Audit Committee received updates on cybersecurity and information security from the Company's Chief Administrative Officer, Chief Security and Information Security Officer, and/or other members of senior leadership and reviewed metrics and trends at four regularly scheduled meetings. The reviews presented to the Audit Committee were followed by an update to the full Board by the Chair of the Audit Committee.

• Within the last three years, the Company has only experienced immaterial information security breaches for which the total expenses incurred were immaterial.

• The Company, including members of the Board, participated in tabletop cybersecurity exercises during 2025.

• The Audit Committee discussed the Company's sustainability-related disclosures, processes, and disclosure frameworks.

• The Corporate Governance Committee regularly reviewed the Company's political expenditures, as well as the Company's processes and priorities related to those political expenditures.

### REPORT OF THE CORPORATE GOVERNANCE COMMITTEE
The following is the report of the Corporate Governance Committee with respect to its philosophy, responsibilities, and initiatives. The Corporate Governance Committee's charter is available on our website at *www.duke-energy.com/our-company/corporate-governance/board-committee-charters/corporate-governance* and is summarized below. Additional information about the Corporate Governance Committee and its members is detailed on page [31](#tCGC) of this proxy statement.

### Philosophy and Responsibilities
We believe that sound corporate governance has three components:

• Board independence;

• processes and practices that foster sound decision-making by both management and the Board; and

• balancing the interests of all of our stakeholders – our investors, customers, employees, the communities we serve, and the environment.

**Membership.** The committee must be comprised of three or more members, all of whom must qualify as independent directors under the listing standards of the NYSE and other applicable rules and regulations.

**Responsibilities.** The committee's responsibilities include, among other things:

• implementing policies regarding corporate governance matters;

• assessing the Board's membership needs and recommending nominees;

• recommending to the Board those directors to be selected for membership on, or removal from, the various Board

committees and those directors to be designated as chairs of Board committees;

• reviewing the CEO succession plan and making recommendations to the Board for the successor to the CEO;

• sponsoring and overseeing annual performance evaluations for the Board and its various committees;

• overseeing Duke Energy's political expenditures and activities pursuant to the Political Expenditures Policy;

• reviewing our charitable contributions and community service policies and practices;

• reviewing Duke Energy's sustainability policies, programs, practices, strategies, goals, and related trends that may affect the Company; and

• reviewing Duke Energy's engagements with shareholders.

The committee may also conduct or authorize investigations into or studies of matters within the scope of the committee's duties and responsibilities, and may retain, at Duke Energy's expense, and in the committee's sole discretion, consultants to assist in such work as the committee deems necessary.

Governance Policies

All of the Board committee charters, as well as our Principles for Corporate Governance, Code of Business Ethics for Employees, and Code of Business Conduct & Ethics for Directors, are available on our website at *www.duke-energy.com/our-company/corporate-governance.* 

Any amendments to or waivers from our Code of Business Ethics for Employees with respect to executive officers or

Code of Business Conduct & Ethics for Directors must be approved by the Board and posted on our website.

In addition, information regarding how to report actual or suspected violations of our codes of ethics, either through our anonymous EthicsLine or otherwise, is provided on the Ethics section of our website at *www.duke-energy.com/our-company/about-us/ethics*.

Succession Planning

The independent directors of the Board are actively involved in our management succession planning process. Throughout the year, they discuss potential successors to key executives and examine backgrounds, capabilities, and appropriate developmental assignments for potential successors. At least annually, the committee or full Board reviews the CEO

succession plan and makes recommendations to the Board for the long term and emergency succession of the CEO. In addition, the Corporate Governance Committee reports to the Board regarding its assessment of how the Company's executive management team is positioned to meet the requirements of Duke Energy's long-term goals.

REPORT OF THE CORPORATE GOVERNANCE COMMITTEE

Board Composition

#### Board Refreshment
The Board annually reviews its composition, skills, and needs in the context of Duke Energy's overall strategy. As part of the Board's overall refreshment, the Board has adopted a retirement policy within our Principles for Corporate Governance.

Pursuant to this policy, the Board considers 75 years, as of the date of the Annual Meeting, to be the maximum age for an independent director to remain on the Board. However, the Corporate Governance Committee actively evaluates the composition of the Board and based on such evaluation, it is understood that not all directors will necessarily remain on the Board until age 75. The Committee's evaluation of the composition of the Board considers diversity, including skills and experiences needed on the Board to properly discharge its responsibilities. The Committee strives to achieve a balance between director refreshment and director continuity, with proper consideration given to avoiding a cluster of retirements in any one year. In this regard, the Committee annually conducts a thorough review of the current composition of the Board and recommends a slate of directors for Board approval to be included in the Company's proxy statement and presented at the Annual Meeting.

**Director Qualifications and Diversity.** The Board recognizes that a diverse Board, management, and workforce are key to Duke Energy's success.

This commitment is evidenced in the backgrounds, skills, and qualifications of the directors who have been nominated.

The Board strives to have members representing a range of experiences and qualifications in areas that are relevant to Duke Energy's business and strategy. As part of the search process, the committee looks for the most qualified candidates, with the following characteristics:

• fundamental qualities, such as high standards of ethics, integrity, and fairness;

• a genuine interest in Duke Energy and a recognition that, as a member of the Board, one is accountable to the shareholders of Duke Energy, not to any particular interest group;

• a broad business background or understanding of business and financial affairs of a large, complex organization;

• a mix of experiences, skills, and qualifications;

• executive management experience at a highly complex organization, such as a corporation, university, or major unit of government, or a professional who regularly advises such organizations;

• no conflict of interest or legal impediment to the duty of loyalty owed to Duke Energy and our shareholders;

• willingness to commit sufficient time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• compatibility and ability to work well with other directors and executives in a team effort with a view to a long-term relationship with Duke Energy as a director;

• independent opinions and willingness to state them in a constructive manner; and

• willingness to become a shareholder of Duke Energy (within a reasonable time of election to the Board).

**Director Candidate Recommendations.** The committee may engage a third-party from time to time to assist in identifying and evaluating director-nominee candidates, in addition to current members of the Board standing for re-election. The committee will provide the third-party, based on the profile described above, the characteristics, skills, and experiences that may complement those of our existing members. The third-party will then provide recommendations for nominees with such attributes. The committee considers nominees recommended by shareholders on a similar basis, taking into account, among other things, the profile criteria described above and the nominee's experiences and skills. In addition, the committee considers the shareholder-nominee's independence with respect to both Duke Energy and the recommending shareholder. All of the nominees on the proxy card were recommended by the committee.

Shareholders interested in submitting nominees as candidates for election as directors must provide timely written notice to the Corporate Governance Committee, c/o David S. Maltz, Vice President, Legal, Chief Governance Officer and Corporate Secretary, Duke Energy Corporation, 525 S. Tryon Street, DEP-09A, Charlotte, NC 28202 or by email to our Corporate Secretary at *InvestDUK@duke-energy.com*. The written notice must set forth, as to each person whom the shareholder proposes to nominate for election as director:

• the name and address of the recommending shareholder(s), and the class and number of shares of common stock of Duke Energy that are beneficially owned by the recommending shareholder(s);

**Shareholder Director Candidate Nominations for Presentation at the 2027 Annual Meeting Not Included in the 2027 Proxy Statement.** Our By-Laws also set forth the procedures that a shareholder must follow to nominate a director candidate pursuant to our advance notice By-Law provision. Please see the *Shareholder Director Nominations and Other Shareholder Proposals for Presentation at the 2027 Annual Meeting Not Included in the 2027 Proxy Statement* section on page [87](#tSDNI) of this proxy statement for more information on the requirements and timing for submission.

**Director Onboarding.** Half of our Board nominees have joined the Board in the last five years. In order to help those new directors quickly transition into their roles on the Board, the director onboarding process has become increasingly important. Immediately following their appointment, each new director meets individually with the senior executives responsible for the Company's major lines of business and operations so that new directors may better understand the issues involved in all aspects of Duke Energy's business. In addition to discussing Duke Energy's businesses and operations, the new directors learn about our corporate governance practices and policies; the financial and technical aspects of our electric utility and natural gas businesses; the enterprise's significant risks; our long-term strategy; and Duke Energy's "all of the above" strategy to meet growing and evolving customer needs.

Finally, new members to our Audit and Compensation and People Development Committees typically have a separate orientation to learn more about each committee's responsibilities, policies, and practices, and the matters that regularly come before the committee.

### DIRECTOR COMPENSATION
Our director compensation program is designed to attract and retain highly qualified directors and align their interests with those of our shareholders. We compensate directors who are not employed by Duke Energy with a combination of cash and equity awards, along with certain other benefits as described below. Ms. Good and Mr. Sideris did not receive compensation for their service on the Board.

The Compensation and People Development Committee annually reviews the director compensation program and recommends proposed changes for approval by the Board. As part of this review, they consider the significant amount of time expended, and the skill level required, by each director not employed by Duke Energy in fulfilling his or her duties on the Board, each director's role and involvement on the Board and its committees and the market compensation practices and levels of our peer companies.

During its annual review of the director compensation program in 2025, the Compensation and People Development Committee considered an analysis prepared by its independent consultant, FW Cook, which summarized director compensation trends for independent directors and pay levels at the same peer companies used to evaluate the compensation of our NEOs. Following this review, and after considering the advice of FW Cook about market practices and pay levels, the Compensation and People Development Committee recommended, and the Board approved, the following changes to our director compensation program: (i) an increase in the Annual Cash Retainer of $10,000; (ii) an increase in the Chair retainer for each of the Audit Committee and the Compensation and People Development Committee of $5,000; (iii) an increase in the Annual Stock Retainer of $20,000; and (iv) an increase in the annual Board Chair Retainer of $100,000 (payable half in cash and half in stock). No other changes were made to our director compensation program during 2025.

As a result of these changes, our 2025 director compensation program consisted of the following:

![[MISSING IMAGE: pc_annualdirectcomp-pn.jpg]](pc_annualdirectcomp-pn.jpg)

**Annual Board Stock Retainer for 2025.** In 2025, each eligible director received the portion of his or her annual retainer that was payable in stock in the form of fully vested shares. The stock retainer was granted under the Duke Energy Corporation 2023 Long-Term Incentive Plan that was approved by our shareholders and generally provides that no non-employee director may be granted equity awards during a calendar year that have a grant date fair value, when added to any cash fees or retainers received for that year, of more than $750,000.

**Deferral Plan.** Directors may elect to defer their annual stock retainer, or all or a portion of their annual cash compensation, under the Directors' Savings Plan. Deferred amounts are credited to an unfunded account, the balance of which is adjusted for the performance of phantom investment options, including the Duke Energy common stock fund, as elected by the director, and generally are paid when the director terminates his or her service from the Board.

**Charitable Giving Program.** The Duke Energy Foundation, independent of Duke Energy, maintains the Duke Energy Foundation Matching Gifts Program under which directors and employees generally are eligible to request matching

contributions of up to $2,500 per director or employee per calendar year to qualifying institutions. In addition, a donation of $1,786 was made to *Keep America Beautiful* in December 2025 on behalf of each of the directors not employed by Duke Energy who served during 2025.

Under the Duke Energy PAC match program, directors are eligible to receive matching contributions of up to $5,000 per year to qualifying institutions.

**Expense Reimbursement and Insurance.** Duke Energy provides travel insurance to directors and reimburses directors for expenses reasonably incurred in connection with attendance and participation at Board and committee meetings and special functions.

**Stock Ownership Guidelines.** Directors are subject to stock ownership guidelines, which establish a minimum level of ownership of Duke Energy common stock (or common stock equivalents). Currently, each director not employed by Duke Energy is required to own shares with a value equal to at least five times the annual Board cash retainer (*i.e.*, an ownership level of $675,000) or retain 50% of his or her vested annual equity retainer. All directors were in compliance with the guidelines as of December 31, 2025.

**PROPOSAL 2:**

RATIFICATION OF DELOITTE & TOUCHE LLP AS DUKE ENERGY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2026

The Audit Committee is directly responsible for the appointment and compensation, including the preapproval of audit fees as described below, and the retention and oversight of the independent registered public accounting firm that audits our financial statements and our internal control over financial reporting. The Audit Committee annually performs an assessment of Deloitte's independence and performance in deciding whether to retain Deloitte or engage a different

independent auditor. Based on this evaluation, the Audit Committee has selected Deloitte as Duke Energy's independent registered public accounting firm for 2026. This appointment is being submitted to shareholders for its ratification as the Audit Committee and the Board believe that the continued retention of Deloitte as our independent registered public accounting firm is in the best interests of Duke Energy and our shareholders.

Independence

Deloitte (or one of its predecessor companies) has served as our independent registered public accounting firm since 1947. Deloitte's level of service, industry experience, and years of experience with Duke Energy have allowed them to gain expertise regarding Duke Energy's operations, accounting policies and practices, and internal control over financial reporting. It also prevents the significant time commitment that educating a new auditor would entail, which could also result in a distraction in focus for Duke Energy management and enables a more efficient fee structure.

To safeguard the continued independence of the independent registered public accounting firm, the Audit Committee adopted a policy that provides that the independent registered public accounting firm is only permitted to provide services to Duke Energy and our subsidiaries that have been preapproved by the Audit Committee. Pursuant to the policy, detailed audit services, audit-related services, tax services, and certain other services have been specifically preapproved up to certain categorical fee limits. Proposed services exceeding the cost of preapproved limits must be approved by the Audit Committee before the independent registered public accounting firm is engaged for such service. All other services that are not prohibited pursuant to the SEC's or other applicable regulatory bodies' rules or regulations must be specifically approved by the Audit Committee before the

independent registered public accounting firm is engaged for such service. All services performed in 2025 and 2024 by the independent registered public accounting firm were approved by the Duke Energy Audit Committee pursuant to its policy on Engaging the Independent Auditor for Services. Information on Deloitte's fees for services rendered in 2025 and 2024 are listed below.

In addition to the annual review of Deloitte's independence and in association with the mandatory rotation of Deloitte's lead engagement partner every five years, the Audit Committee oversees the selection of Deloitte's new lead engagement partner, including discussing candidate qualifications and interviewing potential candidates put forth by Deloitte. Deloitte's lead engagement partner was last approved by the Audit Committee in 2024 effective for the 2024 audit year.

Representatives of Deloitte are expected to participate in the Annual Meeting and will be available to respond to appropriate questions that are submitted in advance of or at the Annual Meeting.

The approval of a majority of shares represented in person or by proxy at the Annual Meeting is required to approve this proposal.

### Audit Fees

The information contained in this report of the Audit Committee shall not be deemed to be "soliciting material" or "filed" or "incorporated by reference" in future filings with the SEC, or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that Duke Energy specifically incorporates it by reference into a document filed under the Securities Act or the Exchange Act.

The purpose of the Audit Committee is to assist the Board in its general oversight of Duke Energy's financial reporting, internal audit functions, and internal controls, including disclosure controls and procedures. The Audit Committee's charter describes in greater detail the full responsibilities of the committee and is available on our website at *www.duke-energy.com/our-company/corporate-governance/board-committee-charters/audit*. Further information about the Audit Committee, its policy on Engaging the Independent Auditor for Services, and its members is detailed on pages [29](#tAUCOOM) and [41](#tP2OD) of this proxy statement.

The Audit Committee has reviewed and discussed the consolidated financial statements of Duke Energy and its subsidiaries with management and Deloitte, Duke Energy's independent registered public accounting firm. Management is responsible for the preparation, presentation, and integrity of Duke Energy's financial statements; accounting and financial reporting principles; establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rule 13a-15); establishing and maintaining internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)); evaluating the effectiveness of disclosure controls and procedures; evaluating the effectiveness of internal control over financial reporting; and evaluating any change in internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting. Deloitte is responsible for performing an independent audit of the consolidated financial statements and expressing an opinion on the conformity of those financial statements with GAAP, as well as expressing an opinion on the effectiveness of internal control over financial reporting based on the criteria established in "Internal Control – Integrated Framework (2013)" issued by the Committee of Sponsoring Organizations of the Treadway Commission.

The Audit Committee reviewed the Company's audited financial statements with management and Deloitte, and met separately with both management and Deloitte to discuss and review those financial statements and reports prior to issuance. These discussions also addressed the quality, not

just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements. Management has represented, and Deloitte has confirmed, that the financial statements for the fiscal year ended December 31, 2025, are fairly presented, in all material respects, in conformity with GAAP.

In addition, management completed the documentation, testing, and evaluation of Duke Energy's system of internal control over financial reporting in response to the Sarbanes-Oxley Act of 2002 and related regulations. The Audit Committee was kept apprised of the progress of the evaluation and provided oversight and advice to management during the process. In connection with this oversight, the Audit Committee received updates provided by management and Deloitte at the regularly scheduled Audit Committee meetings. At the conclusion of the process and prior to the filing of the 2025 Form 10-K with the SEC, management presented to the Audit Committee on the effectiveness of Duke Energy's internal control over financial reporting. The Audit Committee also reviewed the report of management contained in Duke Energy's 2025 Form 10-K filed with the SEC, as well as Deloitte's report included in the Company's 2025 Form 10-K related to its audit of the effectiveness of internal control over financial reporting.

The Audit Committee has discussed with Deloitte the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board. In addition, Deloitte has provided the Audit Committee with the written disclosures and the letter required by Public Company Accounting Oversight Board Ethics and Independence Rule 3526, "Communications with Audit Committees Concerning Independence" that relates to Deloitte's independence from Duke Energy and our subsidiaries and the Audit Committee has discussed with Deloitte the firm's independence.

Based on its review of the consolidated financial statements and discussions with and representations from management and Deloitte referred to above, the Audit Committee recommended to the Board, and the Board approved, that the audited financial statements be included in Duke Energy's 2025 Form 10-K for filing with the SEC.

**PROPOSAL 3:**

ADVISORY VOTE TO APPROVE DUKE ENERGY'S NAMED EXECUTIVE OFFICER COMPENSATION

Duke Energy's shareholders recommended that our Board hold say-on-pay votes on an annual basis. As a result, we are providing our shareholders with the opportunity to approve, on a nonbinding, advisory basis, the compensation of our NEOs as disclosed in this proxy statement. This proposal gives our shareholders the opportunity to express their views on the compensation of our NEOs.

In connection with this proposal, the Board encourages shareholders to review, in detail, the description of the compensation program for our NEOs that is set forth in the Compensation Discussion and Analysis beginning on page [44](#tCDAA) of this proxy statement, as well as the information contained in the compensation tables and narrative discussion in this proxy statement.

As described in more detail in the Compensation Discussion and Analysis section, the guiding principle of our compensation philosophy is that pay should be linked to performance and that the interests of our executives and shareholders should be aligned. Our compensation program is designed to provide significant upside and downside potential depending on actual results as compared to predetermined measures of success. A significant portion of our NEOs' TDC is directly contingent upon achieving specific

results that are important to our long-term success and growth in shareholder value. We supplement our pay for performance program with a number of compensation policies that are aligned with the long-term interests of Duke Energy and our shareholders. We are asking our shareholders to indicate their support for the compensation of our NEOs as disclosed in this proxy statement by voting "FOR" the following resolution:

"RESOLVED, that the shareholders of Duke Energy approve, on a nonbinding, advisory basis, the compensation paid to Duke Energy's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K of the Securities Act, including the Compensation Discussion and Analysis, the compensation tables, and the narrative discussion in Duke Energy's 2026 Proxy Statement."

The approval of a majority of shares represented in person or by proxy at the Annual Meeting is required to approve this proposal. Because your vote is advisory, it will not be binding on the Board, the Compensation and People Development Committee, or Duke Energy. The Compensation and People Development Committee, however, will review the voting results and take them into consideration when making future decisions regarding the compensation of our NEOs.

#### For the Above Reasons the Board of Directors Recommends a Vote "FOR" This Proposal.

### REPORT OF THE COMPENSATION AND PEOPLE DEVELOPMENT COMMITTEE
The Compensation and People Development Committee is responsible for the oversight of Duke Energy's compensation programs and compensation of Duke Energy's executive officers per the Compensation and People Development Committee's charter, which is available on our website at *www.duke-energy.com/our-company/corporate-governance/board-committee-charters/compensation.* 

The Compensation and People Development Committee of Duke Energy has reviewed and discussed the Compensation Discussion and Analysis with management and, based on such review and discussions, the Compensation and People Development Committee recommended to the Board that the Compensation Discussion and Analysis be included in this proxy statement.

### Shareholder Engagement
We have a long-standing history of engaging with, and responding to the feedback provided by, our shareholders and other stakeholders and value the deep relationships we have built. That feedback over time has greatly informed our compensation, stewardship, and governance programs. Given its success, we continued our shareholder outreach program in 2025, reaching out to and engaging with holders of approximately 44% of Duke Energy's outstanding shares of common stock. We also sought to engage with every shareholder who requested to meet with us. These discussions included members of management and, in some instances, our CEO, as well as our Lead Independent Director. Topics discussed with our shareholders in 2025 included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• ***Business and Strategy*** – Updates on our business performance and strategy, including financial results, growth targets, regulatory matters, and strategic initiatives, particularly as we are entering a period of heightened load growth, capital expenditure plan alignment, anticipated energy generation mix through 2050, and exploration of new technologies, while keeping customer reliability and customer value top of mind;

• ***Regulatory and Jurisdictional Considerations*** – Review of relevant regulatory updates, including how we are balancing keeping rates as low as possible and reliability with decarbonization-oriented regulations and legislation;

COMPENSATION DISCUSSION AND ANALYSIS

### Chief Executive Officer Compensation

#### Compensation Changes in 2025 in Connection with CEO Transition
Ms. Good retired from the Company effective on April 1, 2025, and Mr. Sideris was appointed CEO effective April 1, 2025.

In connection with this transition, and after reviewing relevant market data and considering the advice of its independent compensation consultant, the independent members of the Board approved the following compensation adjustments for Mr. Sideris: (i) an increase in his base salary from $900,000 to $1,300,000 effective April 1, 2025; (ii) an increase in his 2025 target STI opportunity from 115% to 150% of his base salary effective April 1, 2025; and (iii) an increase in his 2025 target LTI opportunity from 475% to 750% of his base salary, which was allocated 70% to performance shares and 30% to RSUs. In addition, his Change in Control Agreement (described in more detail on page [58](#tCHANCC)) was amended to increase his severance multiple from 2.00x to 2.99x, which aligns with Ms. Good's prior severance multiple and market norms, and he will have use of the corporate aircraft for personal travel within North America, subject to reimbursement for direct operating costs (other than travel for an annual physical or to attend outside board meetings).

The Compensation and People Development Committee did not make any changes to Ms. Good's 2025 annual base salary (which remained at $1,500,000 through March 31, 2025) or 2025 target STI opportunity (which remained at 200% of base salary, pro-rated for the time she was employed during the year). The Compensation and People Development Committee approved a 2025 LTI opportunity for Ms. Good with a target value of $6 million, which was allocated 70% to performance shares and 30% to RSUs. Per the terms of these equity award agreements, Ms. Good's RSUs will be paid in equal installments on the first three anniversaries of the date of grant and her performance shares will be paid based on actual performance results for the 3-year performance period. Ms. Good did not receive any severance compensation in connection with her retirement.

COMPENSATION DISCUSSION AND ANALYSIS

### Section 2: Compensation Program

### Overall Design
We design our compensation program so that it motivates our executives to focus on our core business priorities and aligns the interests of executives and key stakeholders, including shareholders and customers.

### Elements of Our Total Direct Compensation Program
As discussed in more detail below, during 2025, the components of TDC for our NEOs were base salary, STI compensation, and LTI compensation.

#### Base Salary
The salary for each NEO is based on, among other factors, job responsibilities, level of experience, individual performance, comparisons to the salaries of executives in similar positions at other companies in our peer group and internal comparisons. The Compensation and People Development Committee considers changes in the base salaries of our NEOs at least annually, but changes are not made every year.

During the annual review process in early 2025, the Compensation and People Development Committee approved the following increases in the base salaries of our named executive officers: (i) effective April 1, 2025, a $400,000 increase for Mr. Sideris to reflect his promotion to CEO, as described previously, and (ii) effective March 1, 2025, a 12.7% increase for Mr. Savoy, a 7.8% increase for Mr. Ghartey-Tagoe, a 6.7% increase for Mr. Gillespie, a 12.1% increase for Mr. Renjel, and a 5.6% increase for Ms. Janson. These salary adjustments were intended to align the compensation for each executive with the applicable market median for their roles within the compensation peer group and to address internal equity considerations. The Compensation and People Development Committee did not adjust the base salary for Ms. Good in 2025.

Effective July 1, 2025, Ms. Janson retired as Executive Vice President and CEO, Duke Energy Carolinas, and Mr. Ghartey-Tagoe assumed that role, and Mr. Renjel, who serves as our Executive Vice President and Chief Corporate Affairs Officer, was appointed to the additional role of CEO, Duke Energy Florida and Midwest. In connection with these promotions, and effective July 1, 2025, the Compensation and People Development Committee approved an additional 10.4% increase in base salary for Mr. Ghartey-Tagoe and an additional 10% increase in base salary for Mr. Renjel, in each case to reflect their enhanced roles and responsibilities.

#### Short-Term Incentive Compensation
STI opportunities are provided to our NEOs under the Duke Energy Corporation Executive Short-Term Incentive Plan to promote the achievement of annual performance objectives. Each year, the Compensation and People Development Committee establishes the target STI opportunity for each NEO, which is based on a percentage of his or her base salary. During the annual review process in early 2025, the Compensation and People Development Committee approved the target STI opportunity for each NEO based on the peer group market data, each NEO's responsibilities, and an assessment of his or her individual contributions. In 2025, the Compensation and People Development Committee approved (i) an increase in the annual target STI opportunity for Mr. Sideris from 115% to 150% of his base salary effective upon his promotion to CEO on April 1, 2025, (ii) and an increase in the annual target STI opportunity for Mr. Ghartey-Tagoe from 100% to 105% of his annual base salary effective January 1, 2025 to maintain his position within the median range of the compensation peer group. The STI opportunities for the other NEOs remained unchanged from 2024 levels.

|:---|:---|
| **Name**  | **Target STI Opportunity <br> (as a % of base <br> salary)<sup>(1)</sup>**  |

| Kodwo Ghartey-Tagoe | 105% |
| T. Preston Gillespie | 95% |
| Louis E. Renjel | 95% |

COMPENSATION DISCUSSION AND ANALYSIS

As discussed in more detail below, the Compensation and People Development Committee established the following objectives under the STI plan in February 2025, with the STI target opportunity allocated between corporate and individual objectives as follows:

![[MISSING IMAGE: pc_adjusted-pn.jpg]](pc_adjusted-pn.jpg)

In order to align financial performance with funding of the STI plan, the Compensation and People Development Committee established a performance floor, or circuit breaker, providing that if an adjusted EPS performance level of at least $6.22 was not achieved, the payout levels for all other measures would be reduced up to the payout level for the EPS performance objective. The circuit breaker was set at an amount between the threshold and target levels.

Depending on actual performance, NEOs were eligible to earn a maximum of up to 187.5% of the amount of their STI

target opportunity allocated to corporate objectives, based on a potential maximum payout of 200% for the EPS objective, and a 175% potential maximum payout for the O&M expense, operational excellence, customer satisfaction, energy modernization, and individual objectives.

In order to provide a wider range of potential payouts based on individual performance, in 2025 our STI plan included a performance modifier that could adjust the aggregate payout on the corporate objectives positively or negatively by up to 25%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Goal Setting Process** <br> <u>Financial Performance Measures</u>. The Compensation and People Development Committee believes that tying a portion of the STI payments to adjusted EPS aligns pay outcomes of our NEOs with the interests of shareholders and other stakeholders. <br> • When setting financial goals, the Compensation and People Development Committee reviews our long-term financial plan, as well as the current economic and regulatory environment and expectations for investment opportunities and customer satisfaction. <br>• The Compensation and People Development Committee calibrates the adjusted EPS goal with our publicly announced guidance range and considers industry comparisons and growth expectations to establish the threshold, target, and maximum performance levels. <br>• For 2025, our adjusted EPS guidance range was originally set at $6.17 to $6.42, and the adjusted EPS target under the 2025 STI plan was set in the middle of this guidance range at $6.30. This target exceeded the actual adjusted EPS result of $5.90 under the 2024 STI plan. <br><u>Operational Performance Measures</u>. The Compensation and People Development Committee sets operational performance measure targets at challenging levels to drive long-term growth and success. Stretch performance levels are set to motivate employees to strive for continuous improvement and operational excellence. <br>

COMPENSATION DISCUSSION AND ANALYSIS

Performance Modifier (+/- 25%)

The STI plan provides the Compensation and People Development Committee with flexibility to apply a performance modifier to each named executive officer. If applied, the performance modifier would adjust the aggregate payout level, positively or negatively, by up to 25%. Each year, the Compensation and People Development Committee considers whether to apply the performance modifier based on its evaluation of overall corporate performance and each named executive officer's performance against the individual objectives for that year.

This plan design feature is intended to strengthen our pay for performance culture and reward the contributions made by the NEOs during the year.

Despite the strength of the individual contributions of the named executive officers, the Compensation and People Development Committee elected not to apply the individual performance modifier when determining payouts under the STI plan. Therefore, the individual performance modifier had no impact (positive or negative) on the 2025 STI plan payout levels for the named executive officers.

![[MISSING IMAGE: tb_performancemod-pn.jpg]](tb_performancemod-pn.jpg)

Based on the aggregate corporate and individual performance results, each NEO's aggregate payout under the 2025 STI plan was equal to:

(1) Ms. Good retired on April 1, 2025, and Ms. Janson retired on July 1, 2025. Each of them was entitled to a pro rata STI payment, determined in the same manner as the other NEOs, in the amount of $860,175 and $607,453, respectively.

#### Long-Term Incentive Compensation
Our LTI program is designed to provide our NEOs with an appropriate balance to the STI plan and to align executive and shareholder interests in an effort to maximize shareholder value and further customer interests.

Each year, the Compensation and People Development Committee establishes the target LTI opportunity for each NEO, which is based on a percentage of his or her base salary. During the annual review process in early 2025, the Compensation and People Development Committee approved (i) an increase in the target LTI opportunity for Mr. Sideris from 475% to 750% of his base salary to reflect his promotion to CEO, (ii) an increase in the target LTI opportunity for Mr. Gillespie from 275% to 300%, and (iii) an increase for Ms. Janson from 350% to 450% of base salary, in each case to maintain his or her position within the median range of the compensation peer group. The Compensation and People Development Committee approved a 2025 LTI opportunity for Ms. Good with a target value of $6 million.

Effective July 1, 2025, Ms. Janson retired as Executive Vice President and CEO, Duke Energy Carolinas, and Mr. Ghartey-Tagoe assumed that role, and Mr. Renjel, who serves as Executive Vice President and Chief Corporate Affairs Officer, was appointed to the additional role of CEO, Duke Energy

Florida and Midwest. Although the Compensation and People Development Committee did not adjust the LTI opportunity (expressed as a percentage of base salary) for these two executives in connection with their promotions, it did approve additional equity grants under the LTI program of $148,750 for Mr. Ghartey-Tagoe and of $105,625 for Mr. Renjel, which in each case was prorated based on their promotion date to reflect the incremental LTI value that they would have been granted had their new base salary levels been in effect at the time of the initial 2025 LTI grants.

The 2025 LTI opportunities for the NEOs were as follows.

COMPENSATION DISCUSSION AND ANALYSIS

confirmed that the present mix of performance shares (70% allocation) and RSUs (30% allocation) was consistent with both utility peers and the general industry. The Compensation and People Development Committee believes that this

allocation strikes an appropriate balance to both incentivize and retain our executive officers and aligns with our strong pay for performance philosophy.

2025 – 2027 Performance Shares (70% of Long-Term Incentive Program)

Our Compensation and People Development Committee has designed our performance shares to reflect stakeholder feedback, including shareholders, requesting a focus on multiple core metrics linked to our long-term success and balancing relative and absolute performance in order to emphasize pay for performance comparisons.

In order to emphasize pay for performance, the 2025 – 2027 performance shares vest at the end of the three-year performance period based on the achievement of three performance goals: (i) our cumulative adjusted EPS compared to pre-established targets (40% weighting); (ii) our relative TSR compared to the companies in the UTY (40% weighting); and (iii) a safety measure based on our TICR compared to similar companies in the EEI Group 1 Large Company Index (20% weighting). These performance measures were selected to emphasize their importance in aligning the interests of our executives and shareholders and other stakeholders.

Each of the three performance measures for the 2025 – 2027 performance shares is described below, along with a table that sets forth the performance targets and payout levels.

![[MISSING IMAGE: pc_period-pn.jpg]](pc_period-pn.jpg)

The first performance measure is based on Duke Energy's three-year cumulative adjusted EPS measured against pre-established target levels. The Compensation and People Development Committee established the EPS target for the three-year cycle in February 2025 at a level that reflects an increase over the target level set for the 2024 – 2026 performance period of $18.78. The following table provides the EPS target levels and corresponding payout levels:

---

| | |
|:---|:---|
| **Cumulative Adjusted EPS**  | **Percent Payout of <br> Target 2025 – 2027 <br> Performance Shares**  |
| $20.92 or Higher | 200% |
| ***$19.74 (Target)*** | 100% |
| $17.96 | 50% |
| Lower than $17.96 | 0% |

---

If Duke Energy's cumulative adjusted EPS during the performance period is between $17.96 to $19.74 or between $19.74 to $20.92, the payout for the portion of the

performance shares related to this performance measure is interpolated on a straight-line basis.

![[MISSING IMAGE: pc_tsr-pn.jpg]](pc_tsr-pn.jpg)

The second performance measure is based on the percentile ranking of Duke Energy's TSR for the three-year performance period beginning January 1, 2025, compared to the TSR of each company in the UTY for the same period. The following table provides the percentile ranking and corresponding payout levels:

---

| | |
|:---|:---|
| **Relative TSR <br> Performance Percentile** | **Percent Payout of <br> Target 2025 – 2027 <br> Performance Shares\***  |
| 90<sup>th</sup> or Higher | 200% |
| ***55<sup>th</sup> (Target)*** | 100% |
| 25<sup>th</sup> | 50% |
| Below 25<sup>th</sup> | 0% |

---

\*

If Duke Energy's cumulative TSR is negative during the performance period, the payout is limited to the target level unless Duke Energy's relative performance is in the top quartile. If Duke Energy's cumulative TSR is at least 15%, the payout cannot be less than 30% of the target number of shares related to the TSR portion of the award, regardless of the relative performance.

If Duke Energy achieves a TSR ranking between the 25<sup>th</sup> percentile and the 55<sup>th</sup> percentile or between the 55<sup>th</sup> percentile and the 90<sup>th</sup> percentile, the number of performance shares related to this performance measure is interpolated on a straight-line basis.

To determine performance share payouts, TSR is calculated using the difference between the opening and closing value of the shares of Duke Energy and each peer in the UTY, with dividends assumed to be reinvested. For purposes of the TSR calculation, the opening value is determined based on the average closing stock price for each company's shares on each trading day during the calendar month immediately preceding the performance period, and the closing value is determined based on the average closing stock price for each company's shares on each trading day during the last calendar month in the performance period.

COMPENSATION DISCUSSION AND ANALYSIS

![[MISSING IMAGE: pc_growth-pn.jpg]](pc_growth-pn.jpg)

The third performance measure relates to Duke Energy's safety performance, which is measured based on our TICR for employees, as compared to companies in the EEI Group 1 Large Company Index, excluding companies without gas or nuclear operations. The following table provides the TICR target levels and corresponding payout levels:

---

| | |
|:---|:---|
| **Relative TICR <br> Performance Percentile** | **Percent Payout of <br> Target 2025 – 2027 <br> Performance Shares**  |
| Top Company | 200% |
| ***90<sup>th</sup> (Target)*** | 100% |
| 75<sup>th</sup> | 50% |
| Below 75<sup>th</sup> | 0% |

---

If Duke Energy's safety performance during the performance period is between the 75<sup>th</sup> percentile and 90<sup>th</sup> percentile or between the 90<sup>th</sup> percentile and the Top Company, the payout for the portion of the shares related to this performance measure is interpolated on a straight-line basis.

#### Restricted Stock Units (30% of Long-Term Incentive Program)
The RSUs generally vest in equal installments on the first three anniversaries of the date of grant, provided the recipient continues to be employed by Duke Energy on each vesting date.

#### Payout of 2023 – 2025 Performance Shares
The 2023 – 2025 performance shares for the three-year performance period ending December 31, 2025, generally vest based on: (i) our cumulative adjusted EPS compared to pre-established targets (50% weighting); (ii) our relative TSR compared to the companies in the UTY (25% weighting); and (iii) a safety measure based on our TICR for employees, as compared to companies in the EEI Group 1 Large Company Index, excluding companies without gas or nuclear operations (25% weighting).

![[MISSING IMAGE: tb_performanceshares-pn.jpg]](tb_performanceshares-pn.jpg)

The first measure was based on our cumulative adjusted EPS during the three-year period compared to pre-established targets, as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Cumulative <br> Adjusted EPS** | **Percent Payout of <br> Target 2023 – 2025 <br> Performance Shares**  | **Result**  | **Payout of <br> Target**  |
| $18.75 or Higher | 200% |  |  |
| ***$17.75 (Target)*** | 100% | $17.77 | 102.00% |
| $16.15 | 50% |  |  |
| Lower than $16.15 | 0% |  |  |

---

The second measure was based on our relative TSR for the three-year period compared to the companies in the UTY, as follows:

---

| | | |
|:---|:---|:---|
| **Relative TSR <br> Performance Percentile** | **Percent Payout of <br> Target 2023 – 2025 <br> Performance Shares**  | **Payout of <br> Target\***  |
| 90<sup>th</sup> or Higher | 200% |  |
| ***55<sup>th</sup> (Target)*** | 100% 70<sup>th</sup> Percentile  | 142.86% |
| 25<sup>th</sup> | 50% |  |
| Below 25<sup>th</sup> | 0% |  |

---

\*

If cumulative TSR is negative during the performance period, the payout is limited to the target level regardless of the relative performance. If cumulative TSR is at least 15%, the payout cannot be less than 30% of the target regardless of the relative performance.

In the aggregate, this performance corresponds to a payout of 136.72% of the target number of 2023 – 2025 performance shares, plus dividend equivalents earned during the performance period. The following table lists the number of 2023 – 2025 performance shares in which our NEOs became vested at the end of that performance cycle:

(1) Ms. Good retired on April 1, 2025, and Ms. Janson retired on July 1, 2025. Each of them was entitled to a payout for the 2023-2025 performance shares, determined in the same manner as the other NEOs, in the amount of 154,647 shares and 27,504 shares, respectively.

### Other Elements of Our Compensation Program

#### Retirement and Welfare Benefits
Our NEOs participate in the retirement and welfare plans generally available to other eligible employees. In addition, in order to attract and retain key executive talent, we believe that it is important to provide our NEOs with certain limited retirement benefits that are offered only to a select group of management. These retirement plans provided to our NEOs are described on pages [68](#tDURE) through [69](#tDURE1) of this proxy statement and are generally comparable to the benefits provided by peers of Duke Energy, as determined based on market surveys.

Duke Energy provides our NEOs with the same health and welfare benefits it provides to all other similarly situated employees, and at the same cost charged to all other eligible employees. Our NEOs also are entitled to the same post-retirement health and welfare benefits as those provided to similarly situated retirees.

#### Perquisites
The Compensation and People Development Committee believes it is important to provide only limited perquisites as supported by competitive practice. In 2025, Duke Energy provided our NEOs with the perquisites disclosed in the footnotes to the Summary Compensation Table on page [64](#tEXCO64) of this proxy statement. Duke Energy offers these perquisites, as well as other benefits to certain executives in order to provide competitive total compensation packages. The cost of perquisites and other personal benefits is not part of base salary, and, therefore, does not affect the calculation of

awards and benefits under Duke Energy's other compensation arrangements (*i.e*., retirement and incentive compensation plans).

Our NEOs were eligible to receive the following perquisites and other benefits during 2025: (i) up to $2,500 for the cost of a comprehensive physical examination; (ii) reimbursement of expenses incurred for tax and financial planning services, which program is administered on a three-year cycle, such that participating executives can be reimbursed for up to $15,000 of eligible expenses during the three-year cycle; (iii) up to $2,500 for matching contributions from the Duke Energy Foundation and up to $5,000 for matching contributions under the Duke Energy PAC match program to qualifying charitable institutions; (iv) reimbursement of a portion of the monthly expense for a personal mobile device; and (v) preferred airline status. In addition, we occasionally provide our NEOs with tickets to athletic and cultural events for personal use.

As CEO, Mr. Sideris may use the corporate aircraft for personal travel in North America (on the same basis as Ms. Good prior to her retirement). With advance approval from the CEO, the other NEOs also may use the corporate aircraft for personal travel in North America. If Mr. Sideris or any other NEO uses the corporate aircraft for personal travel, he or she must reimburse Duke Energy for the direct operating costs for such travel. However, Mr. Sideris is not required to reimburse Duke Energy for the cost of travel for an annual physical or to attend outside board meetings. For additional information on the use of the corporate aircraft, see the footnotes to the Summary Compensation Table.

[**TABLE OF CONTENTS**](#TOC)

COMPENSATION DISCUSSION AND ANALYSIS

#### Employment Agreement with Ms. Good
Effective July 2013, Duke Energy entered into an employment agreement with Ms. Good that contained a three-year initial term and automatically renews for additional one-year periods at the end of the initial term unless either party provided 120 days' advance notice. In the event of a change in control of Duke Energy, the term automatically extended to a period of two years. The employment agreement was last amended on June 25, 2015.

Upon a termination of Ms. Good's employment by Duke Energy without "cause" or by Ms. Good for "good reason" (each as defined in her employment agreement), Ms. Good would have been entitled to certain severance benefits. Ms. Good did not receive any severance benefits under her Employment Agreement in connection with her retirement effective April 1, 2025.

#### Severance Plan
The Executive Severance Plan provides severance protection to our current NEOs to provide a consistent approach to executive severance and to provide eligible executives with certainty and security, while they are focusing on their duties and responsibilities. Severance compensation would only be paid in the event that an eligible executive's employment is involuntarily terminated without "cause" or is voluntarily terminated for "good reason," and is subject to compliance with restrictive covenants (*i.e*., confidentiality and non-competition). The severance compensation that would be paid in the event of a qualifying termination of employment to those senior executives who are identified as "Tier I Participants," including our current NEOs, generally approximates two times each NEO's annual compensation and benefits. The Executive Severance Plan prohibits the payment of severance if an executive also would be entitled to severance compensation under a separate agreement or plan maintained by Duke Energy, including the Change in Control Agreements described below. The Executive Severance Plan does not provide for golden parachute excise tax gross-up payments.

The benefit levels under the Executive Severance Plan are described in more detail on page [73](#tRDNEO) under the "Potential

Payments Upon Termination or Change in Control – Severance Protection" section of this proxy statement. Ms. Janson did not receive any severance benefits under the Executive Severance Plan upon her retirement on July 1, 2025, and Ms. Good did not participate in the Executive Severance Plan.

#### Change in Control Agreements
Duke Energy has entered into Change in Control Agreements with our NEOs other than Ms. Good. Under these agreements, each such NEO would be entitled to certain payments and benefits if: (i) a change in control were to occur; and (ii) within two years following the change in control, (a) the executive's employment is terminated without "cause," or (b) the executive terminates his or her employment for "good reason." The severance that would be provided to these NEOs is generally two times the executive's annual compensation and benefits and becomes payable only if there is both a change in control and a qualifying termination of employment. The Compensation and People Development Committee approved the two times severance multiplier after consulting with its advisors and reviewing the severance protection provided by peer companies. As described on page [72](#tPOPAU) of this proxy statement, effective April 1, 2025, Mr. Sideris's Change in Control Agreement contains a severance multiplier of 2.99 rather than two. The Change in Control Agreements do not provide for golden parachute excise tax gross-up payments.

Our RSU and performance share awards provide for "double-trigger" vesting upon a qualifying termination of employment in connection with a change in control.

The Compensation and People Development Committee believes the change in control arrangements are appropriate in order to diminish the uncertainty and risk to the executives' roles in the context of a potential or actual change in control. The benefit levels under the Change in Control Agreements and equity awards are described in more detail on pages [72](#tPOPAU) through [76](#tASSOCD) under the "Potential Payments Upon Termination or Change in Control – Severance Protection" section of this proxy statement.

COMPENSATION DISCUSSION AND ANALYSIS

### Section 3: Competitive Market Practices

### Compensation Consultant
The Compensation and People Development Committee has engaged FW Cook to report directly to the Compensation and People Development Committee as its independent compensation consultant.

The compensation consultant attends each Compensation and People Development Committee meeting and provides advice, including reviewing and commenting on market compensation data used to establish the compensation of the executive officers and directors, the terms and performance goals applicable to incentive plan awards, the process for approving achievement of the incentive goals, and analysis with respect to specific projects and information regarding trends and competitive practices. The compensation consultant also routinely meets with the Compensation and People Development Committee members without management present. When establishing the compensation program for our NEOs, the Compensation and People Development Committee considers input and recommendations from management, including Mr. Sideris, who attends the Compensation and People Development Committee meetings.

The consultant has been instructed that it is to provide completely independent advice to the Compensation and People Development Committee and is not permitted to provide any services to Duke Energy other than at the direction of the Compensation and People Development Committee. With the consent of the Chair of the Compensation and People Development Committee, the consultant may meet with management to discuss strategic issues with respect to executive compensation that will assist the consultant in its engagement with the Compensation and People Development Committee.

The Compensation and People Development Committee has assessed the independence of FW Cook pursuant to SEC rules and concluded that no conflict of interest exists that would prevent the consulting firm from independently advising the Compensation and People Development Committee.

### Compensation Peer Group
One of our core compensation objectives is to attract and retain talented executive officers by providing a total compensation package that generally is competitive with that of other executives and key employees of similarly sized companies with similar complexity, whether within or outside of the utility sector.

The Compensation and People Development Committee, with input and advice from its independent consultant, has developed a customized peer group for the review of executive compensation levels and plan design practices.

The Compensation and People Development Committee, after obtaining advice from its independent consultant at FW Cook, approved the selection criteria for the compensation peer group, so that the group would continue to reflect companies of Duke Energy's scale and business complexity.

The selection criteria include the following: (i) a group of companies whose median market capitalization and revenue

scope is similar in size to Duke Energy, (ii) the largest electric utilities that are constituents of the UTY, or large S&P 500 companies from relevant industries, and (iii) publicly-traded companies that have similar business attributes to Duke Energy (*e.g.,* having at least one of the following business attributes: United States based companies that generate a majority of business domestically, companies that provide products and services in regulated markets, non-utility companies with manufacturing operations, companies requiring high levels of capital investment to generate revenue, and companies paying an annual dividend).

The Compensation and People Development Committee reviews the compensation peer group on an annual basis to ensure it remains appropriate.

The following table reflects the companies in our compensation peer group, based on the selection criteria described above.

COMPENSATION DISCUSSION AND ANALYSIS

### Section 4: Executive Compensation Policies
The following is a summary of our executive compensation policies, which reinforce our pay for performance philosophy and strengthen the alignment of interests of our executives and shareholders:

---

| | | |
|:---|:---|:---|
| **Policy**  | **Description**  | **Description**  |
| **Stock ownership/holding policy**  | We maintain meaningful stock ownership guidelines to reinforce the importance of Duke Energy stock ownership. These guidelines are intended to align the interests of executives and shareholders and to focus the executives on our long-term success. Under these guidelines, each of our active NEOs must own Duke Energy shares in accordance with the following schedule:  | We maintain meaningful stock ownership guidelines to reinforce the importance of Duke Energy stock ownership. These guidelines are intended to align the interests of executives and shareholders and to focus the executives on our long-term success. Under these guidelines, each of our active NEOs must own Duke Energy shares in accordance with the following schedule:  |
|  | &nbsp;&nbsp;&nbsp; **Leadership Position**  | **Value of Shares** |
|  | &nbsp;&nbsp;&nbsp; CEO  | 6x Base Salary |
|  | &nbsp;&nbsp;&nbsp; Other NEOs  | 3x Base Salary |
|  | A NEO also can satisfy the policy by holding 50% of all shares acquired under the LTI program (after payment of any applicable taxes) and 100% of all shares acquired upon the exercise of stock options (after payment of the exercise price and taxes). Each of our NEOs was in compliance with the stock ownership/stock holding policy during 2025. | A NEO also can satisfy the policy by holding 50% of all shares acquired under the LTI program (after payment of any applicable taxes) and 100% of all shares acquired upon the exercise of stock options (after payment of the exercise price and taxes). Each of our NEOs was in compliance with the stock ownership/stock holding policy during 2025. |
| **Clawback policies**  | Under our clawback policy, we are required to recover incentive-based compensation paid to a current or former executive officer with respect to the three years preceding a year in which we prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws. The compensation recoverable is the amount in excess of the amount that would have been payable to the executive officer under the restated financial statements. The clawback must be applied regardless of whether the executive officer was responsible for the error that led to the accounting restatement. The clawback policy is intended to comply with the applicable NYSE listing standards that were revised in response to the mandates under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. We maintain other policies that allow us to recover incentive compensation payments based on an incorrect calculation. In addition, our STI program and LTI programs provide authority to recoup time- and performance-based awards and compensation if we determine at any time that a participant engaged in "detrimental activity" during his or her employment, in which case, to the extent permitted by applicable law, the employee: (a) shall forfeit outstanding awards, and (b) shall be required to promptly return to Duke Energy any payments received under the incentive programs during the three-year period preceding the date of the determination. For this purpose, "detrimental activity" means: (i) the employee engaged in misconduct that is detrimental to our financial condition or business reputation, including due to any adverse publicity, or (ii) the employee violated any of our material written policies, including without limitation our Code of Business Ethics or policies governing workplace harassment, including sexual harassment and other forms of harassment prohibited by our Harassment-Free Workplace Policy.  | Under our clawback policy, we are required to recover incentive-based compensation paid to a current or former executive officer with respect to the three years preceding a year in which we prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws.

| **Hedging or pledging policy**  | We have a policy that prohibits employees (including our NEOs) and directors from trading in put or call options, warrants, swaps, forwards, and other derivatives or similar instruments in connection with Duke Energy securities, or by selling Duke Energy securities "short." Our pledging policy prohibits the pledging of any Duke Energy securities, regardless of where or how such securities are held.

| **Risk assessment policy**  | In consultation with the Compensation and People Development Committee, members of management from Duke Energy's Human Resources, Legal, and Risk Management Departments assessed whether our compensation policies and practices encourage excessive or inappropriate risk taking by our employees, including employees other than our NEOs. This assessment included a review of the risk characteristics of Duke Energy's business and the design of our incentive plans and policies. Management reported its findings to the Compensation and People Development Committee, and after review and discussion, the Compensation and People Development Committee concluded that our plans and policies do not encourage excessive or inappropriate risk taking.  |
| **Shareholder approval policy for severance**  | We have a policy, generally, to seek shareholder approval for any agreements with our NEOs that provide severance compensation in excess of 2.99x the executive's annual compensation or that provide for tax gross-ups in connection with a termination event.  |

### Section 5: Tax and Accounting Implications

### Deductibility of Executive Compensation
The Compensation and People Development Committee reviews and considers the deductibility of executive compensation under Section 162(m) of the Internal Revenue Code, which provides that Duke Energy generally may not deduct, for federal income tax purposes, annual compensation in excess of $1 million paid to certain employees.

The Compensation and People Development Committee has not adopted a policy that would have required all compensation to be deductible because the Compensation and People Development Committee wants to preserve the

ability to pay compensation to our executives in appropriate circumstances, even if such compensation would not be deductible under Section 162(m).

The Compensation and People Development Committee will continue to consider tax implications (including the potential lack of deductibility under Section 162(m)) when making compensation decisions, but reserves the right to make compensation decisions based on other factors believed to be in the best interests of Duke Energy and our shareholders.

### Accounting for Stock-Based Compensation
Stock-based compensation represents costs related to stock-based awards granted to employees and members of the Board. Duke Energy recognizes stock-based compensation based upon the estimated fair value of the awards, net of estimated forfeitures at the date of issuance. The recognition period for these costs begins at either the applicable service inception date or grant date, and continues throughout the

requisite service period or, for certain share-based awards, until the employee becomes retirement eligible, if earlier. Compensation cost is recognized as expense or capitalized as a component of property, plant, and equipment.

### Non-GAAP Financial Measures
As described previously in this Compensation Discussion and Analysis, Duke Energy uses various financial measures, including adjusted EPS, cumulative adjusted EPS, and O&M expense, in connection with short-term and long-term incentives. Adjusted EPS was also used to determine the original forecasted guidance range of $6.17 to $6.42 for 2025. Adjusted EPS and cumulative adjusted EPS are non-GAAP financial measures that represent basic EPS from continuing operations available to Duke Energy Corporation common

shareholders, adjusted for the per share impact of special items. Cumulative adjusted EPS is calculated based on a cumulative three-year basis. Duke Energy uses adjusted EPS as the financial measure to evaluate management performance. As discussed below, special items represent certain charges and credits, which management believes are not indicative of Duke Energy's ongoing performance. A component of the financial performance metric is O&M expense. The O&M expense measure used for incentive

COMPENSATION DISCUSSION AND ANALYSIS

plan purposes also is a non-GAAP financial measure as it represents GAAP O&M adjusted primarily for expenses recovered through rate riders, certain regulatory accounting deferrals, and applicable special items. Management believes the presentation of adjusted EPS provides useful information to investors as an additional relevant comparison of Duke Energy's performance across periods. Management uses adjusted EPS for planning, forecasting and to report financial results to the Duke Energy Board of Directors, employees, and shareholders, as well as analysts and investors. The most directly comparable GAAP measures for adjusted EPS and O&M expense measures used for incentive plan purposes are reported basic EPS available to Duke Energy Corporation common shareholders and reported O&M expense from continuing operations, which includes the impact of special items.

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

• Organizational optimization represents costs associated with strategic repositioning to a fully regulated utility.

• Regulatory matters primarily represents net impairment charges related to Duke Energy Carolinas' and Duke

Energy Progress' North Carolina and South Carolina rate case orders, Duke Energy Carolinas' North Carolina rate case settlement, and charges related to Duke Energy Indiana post-retirement benefits.

• System post-implementation costs represents the net impact of charges related to nonrecurring customer billing adjustments as a result of implementation of a new customer system.

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

• Noncore asset sales and net impairments primarily represents charges related to certain joint venture electric transmission projects and certain renewable natural gas investments.

• Captive storm deductible represents charges related to an insurance deductible for Hurricane Helene property losses.

Duke Energy's adjusted EPS and O&M expense may not be comparable to similarly titled measures of another company because other companies may not calculate the measures in the same manner.

(2) Grant Date Fair Value of Stock Awards for Accounting Purposes: This column does not reflect the value of stock awards that were actually earned or received by our NEOs during each of the years listed above. Rather, as required by applicable SEC rules, this column reflects the aggregate grant date fair value of the performance shares (based on the probable outcome of the performance conditions as of the date of grant) and RSUs granted to our NEOs in the applicable year. The aggregate grant date fair value of the performance shares provided in 2025 to Mr. Sideris, Ms. Good, Mr. Savoy, Mr. Ghartey-Tagoe, Mr. Gillespie, Mr. Renjel, and Ms. Janson, assuming that the highest level of performance would be achieved, is $14,287,398; $8,792,207; $4,026,251; $4,405,382; $3,626,938; $3,255,853; and $6,264,600; respectively. The aggregate grant date fair value of the awards was determined in accordance with the accounting guidance for stock-based compensation. See Note 22 of the Consolidated Financial Statements contained in our 2025 Form 10-K for an explanation of the assumptions made in valuing these awards.

(3) With respect to the applicable performance period, this column reflects amounts payable under the STI plan. Unless deferred, the 2025 amounts were paid in March 2026.

Regarding use of corporate aircraft, NEOs are required to reimburse Duke Energy the direct operating costs of any personal travel, except our CEO who is not required to reimburse Duke Energy for the cost of travel to executive physicals or to meetings of the board of directors of other companies on which board they serve. With respect to flights on a leased or chartered airplane, direct operating costs equal the amount that the third-party charges Duke Energy for such trips. With respect to flights on the corporate aircraft, direct operating costs include the amounts permitted by the Federal Aviation Regulations for non-commercial carriers, including hangar fees, fuel, crew travel expenses, airplane maintenance, aircraft depreciation, catering, labor, and aircraft leases. NEOs are permitted to invite their spouse or other guests to accompany them on business trips when space is available; however, in such events, the NEO is imputed income in accordance with IRS guidelines. The table above includes the amount of the IRS-specified tax deduction disallowance, if any, with respect to the NEO's personal travel. Duke Energy does not provide any tax gross-ups to the NEOs, including with respect to personal use of corporate aircraft.

\*\*

If applicable, includes the cost of benefits under the executive physical exam program, an airline club membership, reimbursement of a portion of the monthly expense for a personal mobile device, retirement gift, and occasional personal use of tickets to athletic and cultural events.

EXECUTIVE COMPENSATION

Duke Energy Retirement Cash Balance Plan

Messrs. Sideris, Savoy, Ghartey-Tagoe, and Gillespie actively participate in the RCBP, which is a noncontributory, defined benefit retirement plan that is intended to satisfy the requirements for qualification under Section 401(a) of the Internal Revenue Code. The RCBP generally covers employees of Duke Energy and affiliates employed or re-employed before January 1, 2014. The RCBP currently provides benefits under a "cash balance account" formula. Certain prior plan formulas are described below. Mr. Sideris, Ms. Good, Mr. Savoy, Mr. Ghartey-Tagoe, Mr. Gillespie, and Ms. Janson have satisfied the eligibility requirements to receive his or her RCBP account benefit upon termination of employment. The RCBP benefit is payable in the form of a lump sum in the amount credited to a hypothetical account at the time of benefit commencement. Payment is also available in annuity forms based on the actuarial equivalent of the account balance. Ms. Good and Ms. Janson each elected and received their RCBP benefit in a lump sum in 2025.

The amount credited to the hypothetical account is increased with monthly pay credits equal to: (i) for participants with combined age and service of less than 35 points, 4% of eligible monthly compensation; (ii) for participants with combined age and service of 35 to 49 points, 5% of eligible monthly compensation; (iii) for participants with combined age and service of 50 to 64 points, 6% of eligible monthly compensation; and (iv) for participants with combined age and service of 65 or more points, 7% of eligible monthly compensation. If the participant earns more than the Social Security wage base, the account is credited with additional pay credits equal to 4% of eligible compensation above the Social Security wage base. Interest credits generally are credited monthly. For Messrs. Savoy, Ghartey-Tagoe, and Gillespie, the interest crediting rate for benefits accrued after 2012 is based on a fixed annual interest factor of 4% and for benefits accrued before 2013, it is based generally on the annual yield on the 30-year Treasury rate (determined quarterly), subject to a minimum of 4% and a maximum of 9%. For Mr. Sideris, the interest crediting rate is based on a fixed annual interest factor of 4%.

For the RCBP, eligible monthly compensation is equal to Form W-2 wages, plus elective deferrals under a 401(k), cafeteria, or 132(f) transportation plan, and deferrals under the Executive Savings Plan. Compensation does not include severance pay, payment for unused vacation (including banked vacation and banked time), expense reimbursements, allowances, cash or noncash fringe benefits, moving expenses, bonuses for performance periods in excess of one year, transition pay, LTI compensation (including income resulting from any stock-based awards, such as stock options, stock appreciation rights, RSUs, or restricted stock), military leave of absence pay (including differential wage payments), and other compensation items to the extent described as not included for purposes of benefit plans or the RCBP. The benefit under the RCBP is limited by maximum benefits and compensation limits under the Internal Revenue Code.

Effective at the end of 2012, the Cinergy Plan was merged into the RCBP. The balances that Ms. Good and Ms. Janson had under the Cinergy Plan's "cash balance account" formula at the end of 2012 were credited to their hypothetical accounts under the RCBP. Prior to 2011, the Cinergy Plan also provided benefits under the Traditional Program formula, which provides benefits based on service and FAP (as defined below). Pursuant to a choice program offered to all non-union participants in the Traditional Program formula in 2006, Ms. Janson elected to participate in the Cinergy Plan's cash balance account formula. Her accrued benefit under the Traditional Program, which is based on service through April 1, 2007, and on pay through December 31, 2016, (with banked vacation taken into account at December 31, 2016) was retained in the plan as well. Ms. Good has always participated in the Cinergy Plan's cash balance account formula.

Under the Traditional Program, in which Ms. Janson participated prior to April 1, 2007, and which was frozen as of December 31, 2016, each participant earns a benefit under a final average pay formula, which calculates pension benefits based on a participant's "highest average earnings" and years of plan participation. The Traditional Program benefit is payable following normal retirement at age 65, following early retirement at or after age 50 with three or more years of service (with reduction in the life annuity for commencement before age 62 in accordance with prescribed factors) and at or after age 55 with combined age and service of 85 points (with no reduction in the life annuity for commencement before normal retirement age). Ms. Janson was eligible for an early retirement benefit, the amount of which would not be reduced for early commencement. Payments to Ms. Janson were available in a variety of annuity forms and in the form of a lump sum that is the actuarial equivalent of the benefit payable to her under the Traditional Program.

The Traditional Program benefit formula is the sum of (a), (b), and (c), where (a) is 1.1% of FAP times years of participation (up to a maximum of 35 years); (b) is 0.5% times FAP in excess of monthly Social Security covered compensation times years of participation (up to a maximum of 35 years); and (c) is 1.55% of FAP times years of participation in excess of 35. The benefit under the Traditional Program will not be less than the minimum formula, which is the sum of (x) and (y), where (x) is the lesser of (i) 1.12% of FAP times years of participation (up to a maximum of 35 years) plus 0.5% times FAP in excess of monthly Social Security covered compensation times years of participation (up to a maximum of 35 years), or (ii) 1.163% of FAP times years of participation (up to a maximum of 35 years); and (y) is 1.492% of FAP times years of participation over 35 years. Social Security covered compensation is the average of the Social Security wage bases during the 35 calendar years ending in the year the participant reaches Social Security retirement age.

EXECUTIVE COMPENSATION

Under the Traditional Program, as part of the administrative record keeping process established in 1998, creditable service for Ms. Janson and similarly situated employees was established from the beginning of the year of hire. The number of actual years of service by Ms. Janson with us or an affiliated company, established from the beginning of the year of hire, is the same as the number of credited years of service under the RCBP (and the ECBP), and, therefore, no benefit augmentation resulted under the RCBP (and the ECBP) to Ms. Janson as a result of any difference in the number of years of actual and credited service. Ms. Janson's years of participation under the Traditional Program were frozen as of April 1, 2007.

FAP is the average of the participant's total pay during the three consecutive years of highest pay from the last ten years of participation at December 31, 2016, (including banked vacation taken into account at December 31, 2016, determined by multiplying the participant's weeks of unused

banked vacation as of December 31, 2016, by the participant's rate of pay as of December 31, 2016). This is determined, at December 31, 2016, using the three consecutive calendar years or last 36 months of participation that yield the highest FAP. Ms. Janson's FAP under the Traditional Program was frozen as of December 31, 2016.

Total pay under the Traditional Program includes base salary or wages, overtime pay, shift premiums, work schedule recognition pay, holiday premiums, retirement bank vacation pay, performance lump-sum pay, annual cash incentive plan awards, and annual performance cash awards. Total pay does not include reimbursements or other expense allowances, imputed income, fringe benefits, moving and relocation expenses, deferred compensation, welfare benefits, long-term performance awards, and executive individual incentive awards. The benefit under the Traditional Program is limited by maximum benefits and compensation limits under the Internal Revenue Code.

Duke Energy Corporation Executive Cash Balance Plan

Mr. Sideris, Ms. Good, Mr. Savoy, Mr. Ghartey-Tagoe, Mr. Gillespie, and Ms. Janson previously earned pay credits under the ECBP, which is a noncontributory, defined benefit retirement plan that is not intended to satisfy the requirements for qualification under Section 401(a) of the Internal Revenue Code. Effective September 30, 2020, the ECBP was frozen with respect to future pay credits, but interest credits continue to be credited on ECBP account balances after September 30, 2020. Prior to this freeze in future benefits, the ECBP generally provided benefits to all employees who participated in the RCBP and whose compensation exceeded the limits under the Internal Revenue Code, including the NEOs listed above. Effective October 1, 2020, each employee who was eligible to earn a benefit under the ECBP as in effect immediately prior to October 1, 2020, became eligible to earn a corresponding benefit under the Executive Savings Plan. Prior to the freeze, benefits earned under the ECBP were attributable to (i) compensation in excess of the annual compensation limit under the Internal Revenue Code that applies to the determination of pay credits under the RCBP; (ii) restoration of benefits in excess of a defined benefit plan maximum annual benefit limit under the Internal Revenue Code that applies to the RCBP; and (iii) supplemental benefits granted to a particular participant. Generally, benefits earned under the RCBP and the ECBP vest upon completion of three years of service, and, with certain exceptions, vested benefits generally become payable upon termination of employment with Duke Energy.

Amounts were credited to a hypothetical account established for Ms. Good under the ECBP pursuant to an amendment that was negotiated in connection with the merger of Cinergy Corp. and Duke Energy. Ms. Good was not eligible to earn any additional benefits under any nonqualified defined benefit

plan (other than future interest credits under the ECBP) until she reached age 62, while still employed with Duke Energy. Upon reaching this threshold in April 2021, Ms. Good became eligible to receive monthly company cash balance contributions under the Executive Savings Plan (rather than under the ECBP, which was frozen in 2020 as previously described). Ms. Good and Ms. Janson each retired and received benefits in the form of a lump sum in 2025 and in early 2026, respectively.

#### Present Value Assumptions
Because the pension amounts shown in the Pension Benefits Table on page [67](#tPENBE) of this proxy statement are the present values of current accrued retirement benefits, numerous assumptions must be applied. The values are based on the same assumptions as used in our 2025 Form 10-K, except as required by applicable SEC rules. Such assumptions include a 5.50% discount rate and an interest crediting rate of 4.84% for benefits accrued before 2013 and 4.00% for benefits accrued after 2012 for Mr. Savoy, Mr. Ghartey-Tagoe, Mr. Gillespie, and Ms. Janson and an interest crediting rate of 4.00% for Mr. Sideris. The assumed form of payment for the RCBP is that a lump sum will be elected 86% of the time and an annuity (*i.e.*, single life annuity, if single, and 100% joint and survivor annuity, if married) will be elected 14% of the time, and the assumed form of payment under the ECBP is a lump sum. The post-retirement mortality assumption is consistent with that used in our 2025 Form 10-K. Benefits are assumed to commence at age 55 for Ms. Janson, and at age 65 for Mr. Sideris, Mr. Savoy, Mr. Ghartey-Tagoe, and Mr. Gillespie or the NEO's current age (if later), and each NEO is assumed to remain employed until that age.

EXECUTIVE COMPENSATION

### Duke Energy Corporation Executive Savings Plan
The Executive Savings Plan generally provides all employees who participate in the Retirement Savings Plan and whose compensation exceeds the limits under the Internal Revenue Code, including the NEOs, with the ability to elect to defer a portion of their base salary and STI compensation. Participants actively employed as of the end of the year also receive a Company matching contribution in excess of the contribution limits prescribed by the Internal Revenue Code under the Retirement Savings Plan, which is the 401(k) plan in which the NEOs participate.\* In addition, participants also receive monthly Company cash balance contributions to the Executive Savings Plan in excess of the contribution limits prescribed by the Internal Revenue Code under the RCBP, which is the pension plan in which the NEOs (other than Mr. Renjel) participate.\*\* Because Mr. Renjel was not eligible to participate in the RCBP due to his date of hire, he was entitled under the Retirement Savings Plan to an additional annual employer retirement contribution equal to 4% of his eligible earnings.

In general, payments are made following termination of employment or death in the form of a lump sum or installments, as selected by the participant. Participants may direct the deemed investment of their account (with certain exceptions) among investment options available under the Retirement Savings Plan, including the Duke Energy Common Stock Fund. Participants may change their investment elections on a daily basis in accordance with the terms of the Executive Savings Plan. The benefits payable under the plan are unfunded and subject to the claims of Duke Energy's creditors.

\*

The Retirement Savings Plan is a tax-qualified "401(k) plan" that provides a means for employees to save for retirement on a tax-favored basis and to receive an employer matching contribution, and, if eligible, an employer retirement contribution. The employer matching contribution is equal to 100% of the NEO's before-tax and Roth 401(k) contributions (excluding "catch-up" contributions) with respect to 6% of eligible pay. For this purpose, "eligible pay" includes base salary and STI compensation. Earnings on amounts credited to the Retirement Savings Plan are determined based on the performance of investment funds (including a Duke Energy Common Stock Fund) selected by each participant. The employer retirement contribution is equal to 4% of eligible earnings.

\*\*

The RCBP is a tax-qualified "cash balance" pension plan that provides a hypothetical account for each participant to which pay credits are credited monthly and to which interest credits are also credited. The Executive Savings Plan does not provide for interest credits, but, instead, allows for participants to direct the investment of their cash balance contributions. See the "Pension Benefits" section for a detailed description of the RCBP on pages [68](#tDURE) - [69](#tTOVKE) of this proxy statement.

EXECUTIVE COMPENSATION

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN

CONTROL – SEVERANCE PROTECTION

Under certain circumstances, each NEO would be entitled to compensation in the event his or her employment terminates or upon a change in control. The amount of the compensation is contingent upon a variety of factors, including the circumstances under which he or she terminates employment. The relevant agreements that each NEO has entered into with Duke Energy are described below, followed by a table on page [75](#tPPUTCS) of this proxy statement that quantifies the amount that would become payable to each NEO as a result of his or her termination of employment.

Except with respect to Ms. Good and Ms. Janson, who retired during 2025, the amounts shown assume that such termination was effective as of December 31, 2025, and are merely estimates of the amounts that would be paid to our NEOs upon their termination. The actual amounts to be paid can only be determined at the time of such NEO's termination of employment.

The table shown on page [75](#tPPUTCS) does not include certain amounts that have been earned and that are payable without regard to the NEO's termination of employment. Such amounts, however, are described immediately following the table.

Under each of the compensation arrangements described below for Mr. Sideris, Mr. Savoy, Mr. Ghartey-Tagoe,

Mr. Gillespie, and Mr. Renjel, "change in control" generally means the occurrence of one of the following: (i) the date any person or group becomes the beneficial owner of 30% or more of the combined voting power of Duke Energy's then outstanding securities; (ii) during any period of two consecutive years, the directors serving at the beginning of such period or who are elected thereafter with the support of not less than two-thirds of those directors cease for any reason other than death, disability, or retirement to constitute at least a majority thereof; (iii) the consummation of a merger, consolidation, reorganization, or similar corporate transaction, which has been approved by the shareholders of Duke Energy, regardless of whether Duke Energy is the surviving company, unless Duke Energy's outstanding voting securities immediately prior to the transaction continue to represent at least 50% of the combined voting power of the outstanding voting securities of the surviving entity immediately after the transaction; (iv) the consummation of a sale of all or substantially all of the assets of Duke Energy or a complete liquidation or dissolution, which has been approved by the shareholders of Duke Energy; or (v) under certain arrangements, the date of any other event that the Board determines should constitute a change in control.

Current Named Executive Officers

Duke Energy entered into a Change in Control Agreement with Mr. Sideris, Mr. Savoy, and Mr. Ghartey-Tagoe, effective as of October 1, 2019; with Mr. Renjel, effective as of May 1, 2021; and with Mr. Gillespie, effective as of February 22, 2023. The agreements have an initial term of two years commencing as of the original effective date, after which the agreements automatically extend, unless six months' prior written notice is provided, on a month-to-month basis. Effective April 1, 2025, in connection with his appointment to CEO, Mr. Sideris's Change in Control Agreement was amended to provide for a severance multiplier of 2.99 rather than two. Mr. Sideris has not entered into an employment agreement with Duke Energy.

The Change in Control Agreements provide for payments and benefits to the executive in the event of termination of employment within two years after a "change in control" by Duke Energy without "cause" or by the executive for "good reason" (each as defined below) as follows: (i) a lump-sum cash payment equal to a pro rata amount of the executive's target bonus for the year in which the termination occurs; (ii) a lump-sum cash payment equal to two times (2.99 for Mr. Sideris) the sum of the executive's annual base salary and target annual bonus opportunity in effect immediately prior to termination or, if higher, in effect immediately prior to the first occurrence of an event or circumstance constituting

"good reason;" (iii) continued medical, dental, and basic life insurance coverage for a two-year period (2.99-year period for Mr. Sideris) or a lump-sum cash payment of equivalent value (reduced by coverage obtained by subsequent employers); and (iv) a lump-sum cash payment of the amount Duke Energy would have allocated or contributed to the executive's qualified and nonqualified defined benefit pension plan and defined contribution savings plan accounts during the two years (2.99 years for Mr. Sideris) following the termination date, plus the unvested portion, if any, of the executive's accounts as of the date of termination that would have vested during the remaining term of the agreement. The agreements also provide for enhanced benefits (*i.e*., two years (2.99 years for Mr. Sideris) of additional vesting) with respect to equity awards.

Under the Change in Control Agreements, each NEO also is entitled to reimbursement of up to $50,000 for the cost of certain legal fees incurred in connection with claims under the agreements. In the event that any of the payments or benefits provided for in the Change in Control Agreement otherwise would constitute an "excess parachute payment" (as defined in Section 280G of the Internal Revenue Code), the amount of payments or benefits would be reduced to the maximum level that would not result in excise tax under Section 4999 of the Internal Revenue Code if such reduction

EXECUTIVE COMPENSATION

would cause the executive to retain an after-tax amount in excess of what would be retained if no reduction were made.

In the event a NEO becomes entitled to payments and benefits under a Change in Control Agreement, he or she would be subject to a one-year noncompetition and nonsolicitation provision from the date of termination, in addition to certain confidentiality and cooperation provisions.

The Executive Severance Plan provides certain executives, including Mr. Sideris, Mr. Savoy, Mr. Ghartey-Tagoe, Mr. Gillespie, and Mr. Renjel with severance payments and benefits upon a termination of employment under certain circumstances. Pursuant to the terms of the Executive Severance Plan, Tier I Participants, which include our NEOs, would be entitled, subject to the execution of a waiver and release of claims, to the following payments and benefits in the event of a termination of employment by (a) Duke Energy other than for "cause" (as defined below), death or disability, or (b) the participant for "good reason" (as defined below): (i) a lump-sum payment equal to a pro rata amount of the participant's annual bonus for the year that the termination of employment occurs, determined based on the actual achievement of performance goals under the applicable performance-based bonus plan; (ii) a lump-sum payment equal to two times the sum of the participant's annual base salary and target annual bonus opportunity in effect immediately prior to termination of employment or, if higher, in effect immediately prior to the first occurrence of an event or circumstance constituting "good reason;" (iii) continued access to medical and dental insurance for a two-year period following termination of employment, with monthly amounts relating to Duke Energy's portion of the costs of such coverage paid to the participant by Duke Energy (reduced by coverage provided to the participant by future employers, if any) and a lump-sum payment equal to the cost of two years of basic life insurance coverage; (iv) one year of outplacement services; and (v) two additional years of vesting with respect to equity awards and an extended period to exercise outstanding vested stock options following termination of employment.

The Executive Severance Plan also provides that, in the event any of the payments or benefits provided for in the Executive Severance Plan otherwise would constitute an "excess parachute payment" (as defined in Section 280G of the Internal Revenue Code), the amount of payments or benefits would be reduced to the maximum level that would not result

in an excise tax under Section 4999 of the Internal Revenue Code if such reduction would cause the executive to retain an after-tax amount in excess of what would be retained if no reduction were made. In the event a participant becomes entitled to payments and benefits under the Executive Severance Plan, he or she would be subject to certain restrictive covenants, including those related to noncompetition, nonsolicitation, and confidentiality.

Duke Energy has the right to terminate any participant's participation in the Executive Severance Plan but must provide the participant with one year's notice and the participant would continue to be eligible for all severance payments and benefits under the Executive Severance Plan during the notice period. Any employee who is eligible for severance payments and benefits under a separate agreement or plan maintained by Duke Energy (such as a Change in Control Agreement) would receive compensation and benefits under such other agreement or plan (and not the Executive Severance Plan).

For purposes of the Change in Control Agreements and the Executive Severance Plan, "cause" generally means, unless cured within 30 days, (i) a material failure by the executive to carry out, or malfeasance or gross insubordination in carrying out, reasonably assigned duties or instructions consistent with the executive's position; (ii) the final conviction of the executive of a felony or crime involving moral turpitude; (iii) an egregious act of dishonesty by the executive in connection with employment, or a malicious action by the executive toward the customers or employees of Duke Energy; (iv) a material breach by the executive of Duke Energy's Code of Business Ethics; or (v) the failure of the executive to cooperate fully with governmental investigations involving Duke Energy. "Good reason," for this purpose, generally means (i) a material reduction in the executive's annual base salary or target annual bonus opportunity as in effect either immediately prior to the change in control or the termination under the Executive Severance Plan (exclusive of any across-the-board reduction similarly affecting substantially all similarly situated employees); or (ii) both a material diminution in the participant's authority, duties, or responsibilities as in effect either immediately prior to the change in control or immediately prior to a Tier I Participant's termination of employment under the Executive Severance Plan and removal of the participant from the Senior Management Committee.

Retired Named Executive Officers

As previously announced, Ms. Good retired from Duke Energy effective April 1, 2025, and Ms. Janson retired from Duke Energy effective July 1, 2025.

Prior to her retirement, Ms. Good was subject to an employment agreement that contained a three-year initial term and automatically renewed for additional one-year periods at the end of the initial term unless either party provided 120 days' advance notice. In the event of a change

in control of Duke Energy, the term automatically extended to a period of two years. Ms. Good could have been entitled to certain severance benefits upon a termination of her employment by Duke Energy without "cause" or by her for "good reason", as previously disclosed in prior proxy statements, but Ms. Good did not actually receive any severance compensation or benefits under her employment agreement in connection with her retirement and the

EXECUTIVE COMPENSATION

severance provisions of her employment agreement terminated on April 1, 2025. However, Ms. Good remains

subject to certain confidentiality, mutual non- disparagement, noncompetition, and nonsolicitation obligations. The noncompetition and nonsolicitation obligations survive for two years following her retirement.

Prior to her retirement, Ms. Janson participated in the Executive Severance Plan (described above). Ms. Janson did not receive any severance compensation or benefits under the Executive Severance Plan in connection with her retirement and she ceased to be a participant in the plan on her retirement date.

Equity Awards – Consequences of Termination of Employment

Each year Duke Energy grants long-term incentives to our executive officers, and the terms of these awards vary somewhat from year to year. The following table summarizes the consequences under Duke Energy's LTI award agreements, without giving effect to, the Change in Control

Agreements or the Executive Severance Plan, that would generally occur with respect to outstanding equity awards in the event of the termination of employment of Mr. Sideris, Mr. Savoy, Mr. Ghartey-Tagoe, Mr. Gillespie, and Mr. Renjel.

Age 55 with at least 10 years of service. In the event a member of the Senior Management Committee (including the NEOs) retires on or after age 60 with at least five years of service (a) following the completion of one year of service after the date of grant, RSUs continue to vest (without proration) and (b) following the completion of at least one year of the performance cycle, performance shares continue to vest (without proration) based on actual performance. In the event a member of the Senior Management Committee (including the NEOs) dies on or after attaining age 60 with at least five years of service and following the completion of at least one year of the performance cycle, performance shares continue to vest (without proration) based on actual performance. With respect to the equity awards granted to each of Ms. Good and Ms. Janson in 2025, this retirement vesting provision applied so long as Ms. Good continued employment through March 31, 2025, and Ms. Janson continued employment through June 30, 2025.

(1) The amounts listed under Cash Severance Payment are payable under (i) the Change in Control Agreements or (ii) the Executive Severance Plan.

(2) The amounts listed under Incremental Retirement Plan Benefit are payable under the terms of the Change in Control Agreements of each NEO. They represent the additional amount that would have been contributed to the RCBP, Retirement Savings Plan, and the Executive Savings Plan in the event the NEO had continued to be employed by Duke Energy for (i) 2.99 years for Mr. Sideris or (ii) two additional years after the actual date of termination for the other NEOs.

(3) The amounts listed under Welfare and Other Benefits include the amount that would be paid to each NEO in lieu of providing continued welfare benefits and basic life coverage. This continued coverage represents two years under the Executive Severance Plan or Change in Control Agreement (except for Mr. Sideris, who receives 2.99 years under the Change in Control Agreement). In addition to the amounts shown above, access to outplacement services for a period of up to one year will be provided after termination under the Executive Severance Plan.

(4) In the event of a termination of employment due to long-term disability, because the payment of RSUs would be delayed for an additional six months as required by applicable tax rules, additional dividend equivalent payments would be made in the amount of $61,728; $23,347; $25,370; $20,515; and $21,187 for Mr. Sideris, Mr. Savoy, Mr. Ghartey-Tagoe, Mr. Gillespie, and Mr. Renjel, respectively.

\*

Ms. Good retired from Duke Energy effective as of April 1, 2025, and Ms. Janson retired from Duke Energy effective as of July 1, 2025. They are not included in the table above because they retired prior to December 31, 2025, and therefore, their termination of employment triggering event is known. Neither Ms. Good nor Ms. Janson received cash severance upon their retirement. However, under the retirement provisions of the applicable equity award agreements, each of them was entitled to vesting of all or part of their equity awards. The Option Exercises and Stock Vested table set forth on page [67](#tOPEX) of this proxy statement includes the value of the equity awards that vested on retirement, in the amount of $27,986,497 for Ms. Good and $4,832,280 for Ms. Janson. The value of the awards that vested upon retirement was calculated based on the actual stock price on the date of vesting for outstanding RSUs and outstanding performance shares (including dividend equivalents) for the 2023 – 2025 performance period. Ms. Good and Ms. Janson also are eligible to vest in performance shares for the 2024 – 2026 and 2025 – 2027 performance periods. These performance shares were not reflected in the Option Exercises and Stock Vested table because they vest based on performance throughout the entire performance period. We estimate that the value of these performance shares is $21,231,666 for Ms. Good and $3,683,339 for Ms. Janson, assuming "target" performance is achieved at the end of the applicable performance period, dividend equivalents based on actual and current dividend rates, and based on our stock price on each of their respective retirement dates. The actual amount realized under the performance shares for the 2024 – 2026 and 2025 – 2027 performance periods will depend on our performance results for each applicable performance period (depending on performance, payout could range from 0% to 200% of target) and our stock price on the date of payment. As is the case with other employees, each of them was entitled to accrued and unpaid benefits under Duke Energy's retirement and deferred compensation plans, as well as a payout for unused vacation.

Assumptions and Other Considerations

The amounts listed on the previous page have been determined based on a variety of assumptions, including with respect to the limits on qualified retirement plan benefits under the Internal Revenue Code. The actual amounts to be paid out can only be determined at the time of each NEO's termination of employment. The amounts described in the table do not include compensation to which each NEO would be entitled without regard to his or her termination of employment, including (i) base salary and STI that have been earned but not yet paid; (ii) amounts that have been earned, but not yet paid, under the terms of the plans listed under the Pension Benefits and Nonqualified Deferred Compensation tables; (iii) unused vacation; and (iv) the potential reimbursement of legal fees.

The amounts shown on the previous page do not reflect the fact that, under the Change in Control Agreements that Duke Energy has entered into with Mr. Sideris, Mr. Savoy,

Mr. Ghartey-Tagoe, Mr. Gillespie, and Mr. Renjel, in the event that payments to any such executive in connection with a change in control otherwise would result in a golden parachute excise tax and lost tax deduction under Sections 280G and 4999 of the Internal Revenue Code, such amounts would be reduced under certain circumstances so that such tax would not apply.

The amounts shown on the previous page with respect to stock awards were calculated based on a variety of assumptions, including the following: (i) the NEO terminated employment on December 31, 2025; (ii) a stock price for Duke Energy common stock equal to $117.21, which was the closing price at the end of 2025; (iii) the continuation of Duke Energy's dividend at the rate in effect during the first quarter of 2026; and (iv) performance at the target level with respect to performance shares.

EXECUTIVE COMPENSATION

Chief Executive Officer Pay Ratio

As required by SEC rules, we are providing the following information about the ratio of the 2025 annual total compensation of Harry Sideris, our CEO, to the annual total compensation of our median employee.

We estimated the median of the 2025 annual total compensation of our employees, using the rules applicable to the Summary Compensation Table, to be $132,604. The annual total compensation of Mr. Sideris, as calculated for the Summary Compensation Table, was $13,652,630, but with his base salary, STI and Company retirement plan contributions annualized in accordance with Item 402(u) of Regulation S-K, his 2025 total compensation would have been disclosed in the Summary Compensation Table as $14,031,983. Therefore, the ratio of our CEO's annualized total compensation to the estimated median of the annual total compensation of our employees was approximately 106 to 1.

To identify the median employee, we reviewed our employee population as of October 31, 2025. We used wages reported in Box 1 of IRS Form W-2 during the ten-month period ending on October 31, 2025, as a consistently applied compensation measure. We did not annualize the wages or make cost of living adjustments. Based on this methodology, we identified a group of employees whose compensation was at the median of the employee data. From this group, we selected an individual who we reasonably believed represented our median employee.

The pay ratio rules provide companies with flexibility to select the methodology and assumptions used to identify the median employee, calculate the median employee's compensation, and estimate the pay ratio. As a result, our methodology may differ from those used by other companies, which likely will make it very difficult to compare pay ratios with other companies, including those within our industry.

The information provided below is mandated by the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, which require that we, among other things, report the amount of "compensation actually paid" to our named executive officers. These amounts are calculated in accordance with applicable SEC rules, and do not reflect the actual amount of compensation earned by or paid to our named executive officers during each applicable year.

The guiding principles of our compensation philosophy are that pay should be linked to performance and that the

interests of our executives and shareholders should be aligned. Our executive officers participate in incentive plans that contain a variety of performance measures that focus not only on financial performance, but also operational excellence, including measures linked to safety, reliability, customer satisfaction, energy modernization, and reportable environmental events. Please refer to the Compensation Discussion and Analysis section of this proxy statement for details regarding how the Compensation and People Development Committee links the compensation paid to our named executive officers to our corporate performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(1) Compensation actually paid ("CAP") was calculated by beginning with the total amount reported in the Summary Compensation Table (the "SCT") for the applicable year, (i) subtracting the grant date fair value of stock awards reported in the Stock Awards column of the SCT ("Stock Awards"), (ii) subtracting the actuarial present value of the accumulated benefit under defined benefit plans reported in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column of the SCT ("Change in Pension Value"), (iii) adding the change in fair value of stock awards for the applicable year, and (iv) adding the service cost and prior service cost for all defined benefit plans for the applicable year. Fair value amounts were computed in a manner consistent with the fair value methodology used to account for share-based payments in our financial statements under GAAP. The fair value amounts were calculated using our stock price on the last day of each fiscal year or the date of vesting, as applicable, and based upon the probable outcome of applicable performance conditions as of the last day of each fiscal year. The service cost and prior service cost for defined benefit plans were calculated using the same methodology as used for our financial statements under GAAP. Following is a reconciliation of the SCT total and the CAP for the CEO for 2025.

(3) Duke Energy TSR represents the cumulative investment return of an initial fixed $100 investment in our common stock on December 31, 2020, assuming reinvestment of all dividends, through the end of the covered fiscal year. The Duke Energy TSR reflected in the table above may not be indicative of future performance. Peer group TSR represents the cumulative investment return of an initial fixed $100 investment in the UTY on December 31, 2020, assuming reinvestment of all dividends, through the end of the covered fiscal year.

(4) Reflects net income attributable to Duke Energy common shareholders, as reported in our Form 10-K for the applicable year.

Of the goals listed above, we consider adjusted EPS to be the most important financial performance measure (that is not otherwise required to be disclosed in the table) used to link executive compensation actually paid to Company performance and therefore include it as the Company-Selected Measure in the table above. Adjusted EPS is a non-GAAP financial measure that represents basic EPS from continuing operations available to Duke Energy Corporation common shareholders, adjusted for the per share impact of special items.

**PROPOSAL 4:** 

AMENDMENT TO THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF DUKE ENERGY CORPORATION TO ELIMINATE SUPERMAJORITY REQUIREMENTS

The Board has unanimously approved, and recommends that shareholders approve, an amendment to the Company's Certificate of Incorporation, substantially in the form attached to this proxy statement as Appendix A, to eliminate the current requirement in the Certificate of Incorporation for an affirmative vote of the combined voting power of 80% of the outstanding shares of all classes of Duke Energy entitled to vote in the election of directors to approve certain actions.

***Background.*** At each of the 2024, 2021, 2018, and 2017 Annual Meetings, the Board recommended that shareholders vote for an amendment to our Certificate of Incorporation to revise the voting requirements for the actions described below from 80% of the outstanding shares of all classes of Duke Energy stock to a simple majority of the outstanding shares of all classes of Duke Energy stock. Despite the Board's support for this amendment, the proposal failed each time, receiving the support of only approximately 64%, 63%, 62%, and 59% of the outstanding shares, respectively. At the 2025 Annual Meeting, Duke Energy's shareholders voted on a shareholder proposal requesting that our Board take the steps necessary to eliminate this super majority requirement in Duke Energy's Certificate of Incorporation. The shareholder proposal was approved by a majority of the votes cast. After review and discussion with shareholders, the Corporate Governance Committee and the Board once again has decided to propose this amendment in the hopes that it will receive the affirmative vote of the combined voting power of 80% of the outstanding shares at the 2026 Annual Meeting.

***Rationale.*** The Board recognizes that supermajority requirements are viewed by many corporate governance experts as overly burdensome and not in line with the best principles in corporate governance. The proposed amendment to the Certificate of Incorporation to eliminate these supermajority requirements is described in more detail below. A draft Certificate of Incorporation containing the text of the proposed amendment is set forth in Appendix A attached hereto.

***Certificate of Incorporation.*** Article Seventh of the Certificate of Incorporation currently requires the affirmative vote of the combined voting power of 80% of the outstanding shares of all classes of Duke Energy to approve, among other things, the following actions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• amend the provision that provides for the method to amend the Certificate of Incorporation (Article Seventh);

• change the number of directors that constitute the Company's Board (Article Fifth, section (b));

• change the method by which vacancies resulting from death, resignation, disqualification, removal or other cause can be filled on the Board (Article Fifth, section (d)); and

• change the method by which directors shall be elected and hold office until the next Annual Meeting (Article Fifth, section (d)).

Upon the approval by our shareholders of the proposed amendment, Article Seventh of our Certificate of Incorporation would be amended as follows, with the proposed deletion stricken through and proposed addition underlined:

"The Corporation reserves the right to supplement, amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by the laws of the State of Delaware and this Certificate of Incorporation, and all rights conferred upon stockholders, directors and officers herein are granted subject to this reservation. Notwithstanding the foregoing, this ARTICLE SEVENTH and sections (b) and (d) of ARTICLE FIFTH may not be supplemented, amended, altered, changed, or repealed in any respect, nor may any provision inconsistent therewith be adopted, unless such supplement, amendment, alteration, change or repeal is approved by the affirmative vote of the holders of at least 80% <u>a majority</u> of the combined voting power of the then outstanding shares of stock of all classes of the Corporation entitled to vote generally in the election of directors, voting together as a single class."

The affirmative vote of holders of at least 80% of the outstanding shares of Duke Energy common stock, the only class of stock outstanding and entitled to vote in the election of directors, is required to approve the amendment to our Certificate of Incorporation described herein. The Board recommends that all shareholders vote in favor of this amendment.

For the Above Reasons the Board of Directors Recommends a Vote "FOR" This Proposal.

If you mail us your properly completed and signed proxy card or vote by phone or online, your shares of Duke Energy common stock will be voted according to the choices that you specify. If you sign and mail your proxy card without marking any choices, your proxy will be voted:

• "FOR" the election of all nominees for director;

• "FOR" the ratification of Deloitte & Touche LLP as Duke Energy's independent registered public accounting firm for 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• "FOR" the advisory vote to approve Duke Energy's named executive officer compensation; and

#### May I change or revoke my vote?
Yes. You may change your vote or revoke your proxy at any time prior to the Annual Meeting by:

• notifying Duke Energy's Corporate Secretary in writing that you are revoking your proxy;

• providing another signed proxy that is dated after the proxy you wish to revoke;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• using the phone or online voting procedures; or

• participating in the Annual Meeting via live webcast and voting online during the Annual Meeting prior to the closing of the polls.

Will my shares be voted if I do not provide my proxy?

It depends on whether you hold your shares in your own name or in the name of a bank or brokerage firm. If you hold your shares directly in your own name, they will not be voted unless you provide a proxy or vote online during the Annual Meeting prior to the closing of the polls. Brokerage firms generally have the authority to vote their customers' unvoted shares on certain "routine" matters. If your shares are held in the name

of a broker, bank, or other nominee, such nominee can vote your shares for the ratification of Deloitte as Duke Energy's independent registered public accounting firm for 2026 if you do not timely provide your proxy because this matter is considered "routine" under the applicable rules. However, no other items are considered "routine" and may not be voted upon by your broker without your instruction.

Plan participant proxies are treated confidentially.

If you elect not to provide voting directions to the plan trustee, the plan trustee will vote the Duke Energy shares allocated to your plan account in the same proportion as those shares held by the plan for which the plan trustee has received voting

directions from other plan participants. The plan trustee will follow participants' voting directions and the plan procedure for voting in the absence of voting directions, unless it determines that to do so would be contrary to the Employee Retirement Income Security Act of 1974.

Because the plan trustee must process voting instructions from participants before the date of the Annual Meeting, you must deliver your instructions no later than May 4, 2026, at 11:59 p.m. Eastern time.

What constitutes a quorum?

As of the record date on March 9, 2026, [•] shares of Duke Energy common stock were issued and outstanding and entitled to vote at the Annual Meeting. In order to conduct the Annual Meeting, a majority of the shares entitled to vote must participate remotely via live webcast or by proxy. This is referred to as a "quorum." If you submit a properly executed proxy card or vote by phone or online, you will be considered part of the quorum. Abstentions and broker "non-votes" will be counted as present and entitled to vote for purposes of

determining a quorum. A broker "non-vote" is not, however, counted as present and entitled to vote for purposes of voting on individual proposals other than ratification of Deloitte as Duke Energy's independent registered public accounting firm. A broker "non-vote" occurs when a bank, broker, or other nominee who holds shares for another person has not received voting instructions from the owner of the shares and, under NYSE listing standards, does not have discretionary authority to vote on a matter.

Who conducts the proxy solicitation and how much will it cost?

Duke Energy is requesting your proxy for the Annual Meeting and will pay all the costs of requesting shareholder proxies. We hired Georgeson LLC to help us send out the proxy materials and request proxies. The estimated fees for Georgeson's services are approximately $27,000, plus out-of-pocket expenses, although the amount could be higher depending on the level of services provided by Georgeson.

In determining the scope of proxy solicitation activities, the Company considered historical voting participation levels, the nature of the matters submitted for shareholder approval, and feedback received through shareholder engagement regarding the appropriate level of solicitation effort. Shareholders generally expressed support for the Company

exercising judgment and discretion in determining the level of resources devoted to solicitation activities.

We can request proxies through the mail or personally by phone, e-mail, or online. We can use directors, officers, and other employees of Duke Energy to request proxies. Directors, officers, and other employees will not receive additional compensation for these services. Certain proxy solicitation costs incurred in connection with the Annual Meeting are attributable, in part, to Proposal 4. We will reimburse brokerage houses and other custodians, nominees, and fiduciaries for their reasonable out-of-pocket expenses for forwarding solicitation material to the beneficial owners of Duke Energy common stock.

Where can I view the replay of the Annual Meeting webcast and the answers to questions submitted by shareholders in advance of or during the Annual Meeting?

A replay of the Annual Meeting webcast, as well as our answers to questions submitted by shareholders before and during the Annual Meeting, will be available until the release

of the proxy statement for the following year at *investors.duke-energy.com/news/default.aspx* under "05/07/2026 – Annual Meeting of Shareholders."

### OTHER INFORMATION

### Discretionary Voting Authority
As of the date this proxy statement was printed, Duke Energy did not anticipate that any matter other than the proposals included in this proxy statement would be raised at the Annual Meeting. If any other matters are properly presented at the

Annual Meeting, the persons named as proxies will have discretion to vote on those matters according to their best judgment.

### Delinquent Section 16(a) Reports
Section 16(a) of the Exchange Act requires Duke Energy's directors and executive officers, and any persons owning more than 10% of Duke Energy's equity securities, to file with the SEC initial reports of beneficial ownership and certain changes in that beneficial ownership with respect to such equity securities of Duke Energy. We prepare and file these reports on behalf of our directors and executive officers. In 2025, to our knowledge, all Section 16(a) reporting requirements applicable to our directors and executive

officers were satisfied in a timely manner, except with respect to Mr. Louis E. Renjel, Executive Vice President and Chief Corporate Affairs Officer. For Mr. Renjel, we inadvertently failed to file 24 Forms 4 with respect to phantom stock units he collectively acquired pursuant to recurring bi-monthly salary deferrals under Duke Energy's Executive Savings Plan from January 1, 2024 to December 31, 2024. A Form 4, filed on January 20, 2026, reported the prior acquisition of these phantom stock units.

### Related Person Transactions
*Related Person Transaction Policy.* The Corporate Governance Committee adopted a Related Person Transaction Policy that sets forth Duke Energy's procedures for the identification, review, consideration, and approval or prohibition of "related person transactions." For purposes of our policy only, a "related person transaction" is a transaction, arrangement, or relationship (or any series of similar transactions, arrangements, or relationships) in which we and any "related person" are, were, or will be participants and where the related person has a direct or indirect material interest in the transaction. Transactions involving compensation for services provided to us as an employee or director are not covered by this policy. A "related person" is any executive officer, director, or beneficial owner of more than 5% of any class of our voting securities, including any of their immediate family members and any entity owned or controlled by such persons. Since January 1, 2025, there have been no related person transactions that were required to be approved under the Company's related person transaction guidelines or reported under the SEC's related person transaction rules. In addition, in the ordinary course of business, in 2025, some of our directors and executive officers, their family members, and affiliated entities received electric and natural gas services on the same terms and conditions provided to other customers. Also, the affiliated entities of some of our directors and officers were involved in transactions that were immaterial to the Company. None of these transactions were directly or indirectly material to the associated director, officer, or affiliated entity.

Under the policy, if a transaction has been identified as a possible related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, our management must present information regarding the related person transaction to our Corporate

Governance Committee (or, if Corporate Governance Committee approval would be inappropriate, to the Board) to approve or prohibit. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us of the transaction, and whether the transaction is on terms that are comparable to the terms available to or from, as the case may be, an unrelated third party or to or from employees generally. Under the policy, we will, on an annual basis, collect information from each director, executive officer, and (to the extent feasible) significant shareholders to enable us to identify any existing or potential related person transactions and to effectuate the terms of the policy. In addition, under our Code of Business Ethics, applicable to all employees, and Code of Business Conduct and Ethics, applicable to all directors, have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest. In considering related person transactions, our Corporate Governance Committee (or Board) will consider the relevant available facts and circumstances, including but not limited to:

• the risks, costs, and benefits to us;

• the impact on a director's independence if the related person is a director, immediate family member of a director, or an entity with which a director is affiliated;

• the availability of other sources for comparable services or products; and

• the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.

The policy requires that, in determining whether to approve or prohibit a related person transaction, our Corporate Governance Committee (or Board) must consider, in light of known circumstances, whether the transaction is, or is not, inconsistent with our best interests and those of our shareholders, as our Corporate Governance Committee (or Board) determines in the good faith exercise of its judgment.

Maltz, Vice President, Legal, Chief Governance Officer and Corporate Secretary, Duke Energy Corporation, 525 S. Tryon Street, DEP-09A, Charlotte, NC 28202.

### Householding Information
Duke Energy has adopted a procedure called "householding," which has been approved by the SEC. Under this procedure, a single copy of the annual report and proxy statement is sent to any household at which two or more shareholders reside, unless one of the shareholders at that address notifies us that they wish to receive individual copies. Each shareholder will continue to receive separate proxy cards, and householding will not affect dividend check mailings or InvestorDirect Choice Plan statement mailings in any way.

If you have previously consented, householding will continue until you are notified otherwise or until you notify Broadridge Investor Communication Solutions, Inc. by mail at Householding Department, 51 Mercedes Way, Edgewood, NY 11717 or by phone at 866.540.7095 that you wish to

receive separate annual reports and proxy statements. You will be removed from the householding program within 30 days of receipt of your notice. If you received a householded mailing this year and you would like to have additional copies of our annual report and proxy statement mailed to you, please submit your request to Broadridge Investor Communication Solutions, Inc. at the number or address listed above. They will promptly send additional copies of the annual report and proxy statement upon receipt of such request.

Many brokerage firms have instituted householding. If you hold your shares in "street name," please contact your bank, broker, or other holder of record to request information about householding.

### APPENDIX A

### AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF DUKE ENERGY CORPORATION
DUKE ENERGY CORPORATION, a corporation organized and existing under the laws of the State of Delaware (the "Corporation"), DOES HEREBY CERTIFY AS FOLLOWS:

1. The name of the corporation is Duke Energy Corporation. The name under which the corporation was originally incorporated was Deer Holding Corp. The name of the corporation was changed to Duke Energy Holding Corp. on June 21, 2005. The original Certificate of Incorporation was filed with the Secretary of State of the State of Delaware on May 3, 2005.

2. This Amended and Restated Certificate of Incorporation, having been duly adopted in accordance with Sections 242 and 245 of the General Corporation Law of the State of Delaware (the "DGCL") and by the approval of the stockholders of the Corporation in accordance with Section 211 of the DGCL, restates and integrates and further amends the provisions of the Amended and Restated Certificate of Incorporation as amended or supplemented heretofore. As so restated and integrated and further amended, the Amended and Restated Certificate of Incorporation (hereinafter, this "Certificate of Incorporation") reads as follows:

<u>Name</u> 

The name of the corporation is Duke Energy Corporation.

ARTICLE THIRD

<u>Purpose</u> 

The purpose of the Corporation is to engage in any lawful act or activity for which a corporation may be organized under the DGCL.

ARTICLE FOURTH

<u>Capital Stock</u> 

(a) The aggregate number of shares of stock that the Corporation shall have authority to issue is two billion forty-four million (2,044,000,000) shares, consisting of two billion (2,000,000,000) shares of Common Stock, par value $0.001 per share (the "Common Stock"), and forty-four million (44,000,000) shares of Preferred Stock, par value $0.001 per share (the "Preferred Stock").

(b) The Board of Directors of the Corporation shall have the full authority permitted by law, at any time and from time to time, to divide the authorized and unissued shares of Preferred Stock into one or more classes or series and, with respect to each such class or series, to determine by resolution or resolutions the number of shares constituting such class or series and the designation of such class or series, the voting powers, if any, of the shares of such class or series, and the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of any such class or series of Preferred Stock to the full extent now or hereafter permitted by the law of the State of Delaware. The powers, preferences and relative, participating, optional and other special rights of each class or series of Preferred Stock and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other classes or series at any time outstanding.

(c) Subject to applicable law and the rights, if any, of the holders of any class or series of Preferred Stock or any class or series of stock having a preference over or the right to participate with the Common Stock with respect to the payment of dividends, dividends may be declared and paid on the Common Stock at such times and in such amounts as the Board of Directors of the Corporation in its discretion shall determine.

proportion to the full amounts to which they are entitled or in such order or priority, if any, as will have been fixed in the resolution or resolutions providing for the issue of the class or series of Preferred Stock. Neither the merger or consolidation of the Corporation into or with any other corporation, nor a sale, transfer or lease of all or part of its assets, will be deemed a liquidation, dissolution or winding up of the Corporation within the meaning of this paragraph, except to the extent specifically provided in any certificate of designation for any class or series of Preferred Stock. Nothing in this ARTICLE FOURTH shall limit the power of the Board of Directors to create a class or series of Preferred Stock for which the amount to be distributed upon any liquidation, dissolution or winding up of the Corporation is calculated by reference to, and the payment of which is concurrent with, the amount to be distributed to the holders of shares of Common Stock.

(f) Except as otherwise required by law and subject to the rights of the holders of any class or series of Preferred Stock, with respect to all matters upon which stockholders are entitled to vote or to which stockholders are entitled to give consent, the holders of any outstanding shares of Common Stock shall vote together as a class, and every holder of Common Stock shall be entitled to cast thereon one vote in person or by proxy for each share of Common Stock standing in such holder's name on the books of the Corporation; *provided*, *however*, that, except as otherwise required by law, or unless provided in any certificate of designation for any class or series of Preferred Stock, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any certificate of designations relating to any class or series of Preferred Stock) that relates solely to the terms of one or more outstanding classes or series of Preferred Stock if the holders of such affected class or series are entitled, either separately or together with the holders of one or more other such classes or series, to vote thereon pursuant to this Certificate of Incorporation (including any certificate of designations relating to any class or series of Preferred Stock) or pursuant to applicable law. Subject to the rights of the holders of any class or series of Preferred Stock, stockholders of the Corporation shall not have any preemptive rights to subscribe for additional issues of stock of the Corporation and no stockholder will be permitted to cumulate votes at any election of directors.

ARTICLE FIFTH

<u>Board of Directors</u> 

(a) The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

(b) Except as otherwise fixed by or pursuant to provisions of ARTICLE FOURTH relating to the rights of the holders of any series of Preferred Stock, the number of directors of the Corporation shall not be less than nine (9) nor more than eighteen (18), as may be fixed from time to time by the Board of Directors.

(c) A director may be removed from office with or without cause; *provided*, *however*, that, subject to applicable law, any director elected by the holders of any series of Preferred Stock may be removed without cause only by the holders of a majority of the shares of such series of Preferred Stock.

(d) Except as otherwise fixed by or pursuant to provisions of ARTICLE FOURTH relating to the rights of the holders of any series of Preferred Stock, newly created directorships resulting from any increase in the number of directors and any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other cause shall be filled only by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors. Any director elected in accordance with the preceding sentence shall hold office until the next succeeding annual meeting of stockholders and until his or her successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

(e) Except as otherwise fixed by or pursuant to provisions of ARTICLE FOURTH relating to the rights of the holders of any series of Preferred Stock, the directors shall be elected by the holders of voting stock and shall hold office until the next annual meeting of stockholders and until their respective successors shall have been duly elected and qualified, subject, however, to prior death, resignation, retirement, disqualification or removal from office.

(f) Election of directors need not be by written ballot unless the By-Laws so provide.

(g) In addition to the powers and authority hereinbefore or by statute expressly conferred upon them, the directors are hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation, subject, nevertheless, to the provisions of the DGCL, this Certificate of Incorporation, and any By-Laws adopted by the stockholders; provided, however, that no By-Laws hereafter adopted by the stockholders shall invalidate any prior act of the directors which would have been valid if such By-Laws had not been adopted.

[**TABLE OF CONTENTS**](#TOC)

APPENDIX A

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(a) Meetings of stockholders may be held within or without the State of Delaware, as the By-Laws may provide. The books of the Corporation may be kept (subject to any provision contained in the DGCL) outside the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the By-Laws of the Corporation

(b) Written Consent. Certain actions required or permitted to be taken by the stockholders of the Corporation at an annual or special meeting of the stockholders may be effected without a meeting by the written consent of the holders of common stock of the Corporation (a "Consent"), but only if such action is taken in accordance with the provisions of this Article Sixth, the Corporation's By-laws and applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i) Record Date. The record date for determining such stockholders entitled to consent to corporate action in writing without a meeting shall be as fixed by the Board of Directors or as otherwise established under this Article Sixth. Any holder of common stock of the Corporation seeking to have the stockholders authorize or take corporate action by Consent shall, by written request addressed to the secretary of the Corporation and delivered to the Corporation's principal executive offices and signed by holders of record at the time such request is delivered representing at least 20 percent (20%) of the outstanding shares of common stock of the Corporation, request that a record date be fixed for such purpose. The written request must contain the information set forth in paragraph (b)(ii) of this Article Sixth. Following delivery of the request, the Board of Directors shall, by the later of (x) 20 days after delivery of a valid request to set a record date and (y) 5 days after delivery of any information required by the Corporation to determine the validity of the request for a record date or to determine whether the action to which the request relates may be effected by Consent under paragraph (b)(iii) of this Article Sixth, determine the validity of the request and whether the request relates to an action that may be taken by Consent and, if appropriate, adopt a resolution fixing the record date for such purpose. The record date for such purpose shall be no more than 10 days after the date upon which the resolution fixing the record date is adopted by the Board of Directors and shall not precede the date such resolution is adopted. If a request complying with the second and third sentences of this paragraph (b)(i) has been delivered to the secretary of the Corporation but no record date has been fixed by the Board of Directors by the date required by the preceding sentence, the record date shall be the first date on which a signed Consent relating to the action taken or proposed to be taken by Consent is delivered to the Corporation in the manner described in paragraph (b)(vi) of this Article Sixth; provided that, if prior action by the Board of Directors is required under the provisions of Delaware law, the record date shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii) Request Requirements. Any request required by paragraph (b)(i) of this Article Sixth (a) must be delivered by the holders of record of at least 20% of the outstanding shares of common stock of the, who shall not revoke such request and who shall continue to own not less than 20% of the outstanding shares of common stock of the Corporation through the date of delivery of Consents signed by a sufficient number of stockholders to authorize or take such action; (b) must contain an agreement to solicit Consents in accordance with paragraph (b)(iv) of this Article Sixth, (c) must describe the action proposed to be taken by written consent of stockholders and (d) must contain (1) such information and representations, to the extent applicable, then required by Section 2.03(b) of the Corporation's By-laws as though such stockholder was intending to propose an amendment to the Corporation's Restated Certificate of Incorporation or By-laws or other business to be brought before a meeting of stockholders and (2) the text of the proposed action to be taken (including the text of any resolutions to be adopted by Consent) and (e) must include documentary evidence that the requesting stockholder(s) own in the aggregate not less than 20% of the outstanding shares of common stock of the Corporation as of the date of such written request to the secretary; provided, however, that if the stockholder(s) making the request are not the beneficial owners of the shares representing at least 20% of the outstanding shares of common stock of the Corporation, then to be valid, the request must also include documentary evidence (or, if not simultaneously provided with the request, such documentary evidence must be delivered to the secretary within ten business days after the date on which the request is delivered to the secretary) that the beneficial owners on whose behalf the request is made beneficially own at least 20% of the outstanding shares of common stock of the Corporation as of the date on which such request is delivered to the secretary. If the action proposes to elect directors by written consent, the written request for a record date must also contain the information required by Section 3.03 of the Corporation's By-laws. The Corporation may require the stockholder(s) submitting such request to furnish such other information as may be reasonably requested by the Corporation. Any requesting stockholder may revoke his, her or its request at any time by written revocation delivered to the secretary of the Corporation at the Corporation's principal executive offices. Any disposition by a requesting stockholder of any shares of common stock of the Corporation (or of beneficial ownership of such shares by the beneficial owner on whose behalf the request was made) after the date of the request, shall be deemed a revocation of the request with respect to such shares, and each requesting stockholder and the applicable beneficial owner shall certify to the secretary of the Corporation on the day prior to the record date set for the action by written consent as to whether any such disposition has occurred. If the unrevoked requests represent in the aggregate less than 20% of the outstanding shares of common stock of the Corporation, the Board of Directors, in its discretion, may cancel the action by written consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iii) Actions Which May Be Taken by Written Consent.

APPENDIX A

immediately preceding annual meeting and ending on the date of the next annual meeting; (d) an identical or substantially similar item of business (as determined by the Board of Directors of the Corporation in its reasonable determination, which determination shall be conclusive and binding on the Corporation and its stockholders, (a "Similar Item")), was presented at a meeting of stockholders held not more than 12 months before the request is received by the secretary of the Corporation; (e) a Similar Item consisting of the election or removal of directors was presented at a meeting of stockholders held not more than 90 days before the request is received by the secretary of the Corporation (and, for purposes of this clause, the election or removal of directors shall be deemed a "Similar Item" with respect to all items of business involving the election or removal of directors), (f) a Similar Item is included in the Corporation's notice of meeting as an item of business to be brought before an annual or special stockholders meeting that has been called but not yet held or that is called to be held within 90 days after the request is received by the secretary of the Corporation; or (g) such record date request was made in a manner that involved a violation of Regulation 14A under the Securities Exchange Act of 1934 or other applicable law. For purposes of this paragraph (b)(iii), the nomination, election or removal of directors shall be deemed to be a Similar Item with respect to all actions involving the nomination, election or removal of directors, changing the size of the Board of Directors and filling of vacancies and/or newly created directorships resulting from any increase in the authorized number of directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iv) Manner of Consent Solicitation. Holders of common stock of the Corporation may take action by written consent only if Consents are solicited from all holders of common stock of the Corporation entitled to vote on the matter and in accordance with applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (v) Date of Consent. Every Consent purporting to take or authorize the taking of corporate action must bear the date of signature of each stockholder who manually signs the Consent, and no Consent shall be effective to take the corporate action referred to therein unless, within 60 days of the earliest dated Consent delivered in the manner required by paragraph (b)(vi) of this Article Sixth and not later than 120 days after the record date, Consents signed by a sufficient number of stockholders to take such action are so delivered to the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (vi) Delivery of Consents. No Consents may be dated or delivered to the Corporation or its registered office in the State of Delaware until 60 days after the delivery of a valid request to set a record date. Consents must be delivered to the Corporation by delivery to its registered office in the State of Delaware or its principal place of business. Delivery must be made by hand or by certified or registered mail, return receipt requested. The secretary of the Corporation shall provide for the safe-keeping of such Consents and any related revocations and shall promptly designate one or more persons, who shall not be members of the Board of Directors, to serve as inspectors ("Inspectors") with respect to such Consents. The Inspectors shall promptly conduct a ministerial review of the sufficiency of all Consents and any related revocations and of the validity of the action to be taken by written consent as the secretary of the Corporation deems necessary or appropriate, including, without limitation, whether the stockholders of a number of shares having the requisite voting power to authorize or take the action specified in Consents have given consent. If after such investigation the Inspectors shall determine that the action purported to have been taken is duly authorized by the Consents, that fact shall be certified on the records of the Corporation kept for the purpose of recording the proceedings of meetings of stockholders and the Consents shall be filed in such records. In conducting the investigation required by this section, the Inspectors of the Corporation may, at the expense of the Corporation, retain special legal counsel and any other necessary or appropriate professional advisors as such person or persons may deem necessary or appropriate and, to the fullest extent permitted by law, shall be fully protected in relying in good faith upon the opinion of such counsel or advisors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (vii) Effectiveness of Consent. No action may be taken by the stockholders by Consent except in accordance with this Article Sixth. If the Board of Directors shall determine that any request to fix a record date was not properly made in accordance with, or relates to an action that may not be effected by Consent pursuant to, this Article Sixth, or the stockholder or stockholders seeking to take such action do not otherwise comply with this Article Sixth, then the Board of Directors shall not be required to fix a record date and any such purported action by Consent shall be null and void to the fullest extent permitted by applicable law. No Consent shall be effective until such date as the Inspectors certify to the Corporation that the Consents delivered to the Corporation in accordance with paragraph (vi) of this Article Sixth, represent at least the minimum number of votes that would be necessary to take the corporate action at a meeting at which all shares entitled to vote thereon were present and voted, in accordance with Delaware law and this Certificate of Incorporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (viii) Challenge to Validity of Consent. Nothing contained in this Article Sixth shall in any way be construed to suggest or imply that the Board of Directors of the Corporation or any stockholder shall not be entitled to contest the validity of any Consent or related revocations, whether before or after such certification by the Inspectors, as the case may be, or to prosecute or defend any litigation with respect thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ix) Board-solicited Stockholder Action by Written Consent. Notwithstanding anything to the contrary set forth above, (x) none of the foregoing provisions of this Article Sixth shall apply to any solicitation of stockholder action by written consent by or at the direction of the Board of Directors and (y) the Board of Directors shall be entitled to solicit stockholder action by written consent in accordance with applicable law.

### APPENDIX B
Cautionary Note 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, 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 AI;

• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

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

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

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

• 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;

• The ability to control operation and maintenance costs;

• The level of creditworthiness of counterparties to transactions;

• The ability to obtain adequate insurance at acceptable costs and recover on claims made;

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

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

• The performance of projects undertaken by our businesses and the success of efforts to invest in and develop new opportunities;

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

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

• The impacts from potential impairments of goodwill or investment carrying values;

• Asset or business acquisitions and dispositions may not be consummated or yield the anticipated benefits, which could adversely affect our financial condition, credit metrics or ability to execute strategic and capital plans; and

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

Additional risks and uncertainties are identified and discussed in the Company's and its subsidiaries' reports filed with the SEC and available at the SEC's website at www.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 Duke Energy expressly disclaims an obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

### APPENDIX C

#### Adjusted Earnings per Share (EPS)
The materials include discussion of adjusted EPS. The materials also include references to the forecasted 2026 adjusted EPS guidance range and related growth rates. The non-GAAP financial measure, adjusted EPS, represents basic EPS from continuing operations available to Duke Energy Corporation common shareholders (GAAP reported EPS), adjusted for the 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.

However, management believes the presentation of adjusted EPS provides useful information to investors, as an additional relevant comparison of Duke Energy's performance across periods. Management uses adjusted EPS for planning, forecasting and to report financial results to the Duke Energy Board of Directors, employees, and shareholders, as well as analysts and investors. Adjusted EPS is also used as a basis to determine employee incentive bonuses. The most directly comparable GAAP measure for adjusted EPS is reported basic EPS available to Duke Energy Corporation common shareholders.

Due to the forward-looking nature of forecasted adjusted EPS and related growth rates, the information to reconcile those amounts to the most directly comparable GAAP financial measure is not available, as management is unable to project special items, such as legal settlements, impacts of regulatory orders or asset impairments, for future periods.
