<u>Letter toOur Shareholders</u>  

April 1, 2026

**Dear Fellow Shareholders,**

Thank you for your investment and trust in FirstEnergy.

Over the last three years, we have made FirstEnergy into a stronger and more agile company focused on delivering a positive customer experience and sustainable long-term value. Our performance in 2025 reflects the impact of this work. We executed well, improved service reliability, advanced our regulatory strategy, and delivered strong financial results. We demonstrated the power of our business model and built a solid foundation for continued growth.

I value the close partnership with our Board and leadership team as we continue executing our strategy with a steadfast commitment to good governance.

**Delivering results** 

In 2025 we advanced our cultural, structural and leadership transformation. We moved decision-making closer to our customers by decentralizing operational, financial and regulatory functions and strengthening accountability. With this alignment, we achieved constructive regulatory outcomes that support needed investments in service reliability.

We delivered on each of our key financial targets, including Core Earnings (non-GAAP) per share, base O&M, capital investments and cash from operations. In December, S&P upgraded our credit ratings, reflecting our stronger financial profile and the progress we have made moving beyond legacy matters.

We deployed $5.6 billion in capital through our Energize365 program in 2025 to enhance reliability, resiliency and system capacity. These investments are driving measurable benefits, including a 10% improvement in systemwide distribution reliability compared to 2024.

Our 2025 performance shows our strategy is working. We have a clear roadmap to build on this success. In early 2026, we expanded our Energize365 program to $36 billion for 2026-2030, a 30% increase over our prior five-year plan. This reflects our financial strength and our responsibility to meet customer expectations for reliability and grid resiliency, while offering a compelling, low-risk value proposition to investors.

**Building for the future**

Our meaningful growth opportunities extend well beyond our current plan. Data center development, advanced manufacturing and electrification are reshaping demand patterns, while rising customer expectations require a more modern, resilient system. These needs align with our assets, location and business model.

In February we filed for approval of a fully regulated, 1.2 gigawatt combined-cycle natural gas facility in Maidsville, West Virginia. This project represents a significant opportunity to keep power reliable and affordable for our West Virginia customers and support the state's broader energy objectives.

**2026** PROXY STATEMENT<br>

------

<u>Letter toOur Shareholders</u>  

We also expect substantial long-term transmission investment. Across our footprint, nearly 70% of our lines and 30% of our substation assets will approach end-of-life over the next decade. We plan to pursue additional opportunities through PJM's competitive Open Window process to support the region's growing transmission needs. With our extensive, well-situated transmission network, FirstEnergy will continue to play a critical role as an engine of economic development keeping affordability and reliability at the center of our work.

**Enhancing our performance culture**

Our progress is driven by our employees. In 2025 we advanced a more efficient and sustainable operating model to empower our teams and elevate our performance culture. We also brought 2,500 employees back to the office to support greater collaboration and engagement. These actions reinforce our focus on continuous improvement and execution.

Ethical conduct is foundational to how we operate and make decisions. We were proud to earn recognition for governance and transparency through the CPA-Zicklin Trendsetter designation and Ethisphere Compliance Leader verification. We remain committed to maintaining the highest standards of ethics, integrity and compliance.

**Creating shareholder value**

Our clear strategy and disciplined execution are delivering results. In 2025 we generated total shareholder returns (TSR), including dividends, of 17.3%. This compares to average TSR of 15.5% for our regulated peers in the S&P 500 Utility Index.

We remain focused on building our momentum and driving strong, reliable performance. With continued Board approval, we expect to declare dividends totaling $1.86 per share in 2026. This represents a 4.5% increase from 2025 and aligns with our target payout ratio.

**Looking ahead**

I appreciate the commitment of our employees, leadership and Board as we continue transforming FirstEnergy into a premier electric company. I also want to thank Melvin Williams for his five years of service on our Board. His perspective and leadership strengthened our company and supported our progress.

Our organization is aligned around our mission to deliver safe, reliable and affordable service to the 6 million customers who depend on us while creating long-term value for you, our shareholders. I am proud of what we've achieved and confident in our future.

We look forward to continuing our dialogue with you at the 2026 Annual Meeting and throughout the year.

Thank you for your continued support of our company.

the risks and uncertainties associated with litigation, including the securities class-action lawsuit, regulatory proceedings, arbitration, mediation and similar proceedings; changes in national and regional economic conditions, including recession, volatile interest rates, inflationary pressure, supply chain disruptions, higher fuel costs, and workforce impacts, affecting us and/or our customers and the vendors with which we do business; variations in weather, such as mild seasonal weather variations and severe weather conditions (including events caused, or exacerbated, by climate change, such as wildfires, hurricanes, flooding, droughts, high wind events and extreme heat events) and other natural disasters, which may result in increased storm restoration expenses or material liability and negatively affect future operating results;

## Executive Compensation Highlights
Under our compensation design, the percentage of pay that is based on performance increases as the responsibilities of a Named Executive Officer ("NEO") increase. The charts below illustrate the mix of annualized base salary, 2025 target short-term incentive program ("STIP") and target long-term incentive program ("LTIP") awards for our NEOs. For 2025, approximately 60% of the President and CEO's total target annual pay and 53% of our other NEOs' average annual target pay was variable and could be reduced to zero if performance metrics are not met at a minimum threshold level. The values shown are effective as of December 31, 2025 for the NEOs who were serving as executive officers as of December 31, 2025.

![img217999304_21.jpg](img217999304_21.jpg)

We believe that our executive compensation philosophy and practices align with the long-term interests of our shareholders and with commonly viewed best practices in the market.

Our executive compensation practices are described in greater detail in the "Executive Compensation" section of this proxy statement, beginning on page 33.

**Shift to Core EPS and Corresponding Changes to Executive Compensation Program**

In early 2025, in order to provide our shareholders additional transparency regarding the performance of our regulated operations, the Company made a strategic change to how we measure and report our financial results. This change culminated in the Company discontinuing its historic practice of reporting on the basis of Operating Earnings per share (non-GAAP) ("Operating EPS") and shifting to reporting on the basis of Core Earnings per share ("Core EPS"). Core EPS is a non-GAAP metric that (i) includes the results of the Company's four business segments: Distribution, Integrated, Stand-Alone Transmission and Corporate and (ii) is reduced by excluding the often volatile and unpredictable income from our non-core, legacy investment in the Signal Peak coal mine, which was sold in June 2025, and net periodic pension and other post-employment benefits credits. Special items continue to be excluded from earnings calculations as has historically been the case. Effective as of the quarter ended March 31, 2025, the Company has transitioned fully to reporting and providing financial results based on Core EPS. The Company has ceased reporting and providing financial results based on Operating EPS, as that metric no longer serves as an appropriate measure of the Company's performance as managed.

Consistent with this strategic change, on June 17, 2025, the Board, upon recommendation by the Compensation Committee and with input from the Compensation Committee's independent compensation consultant, approved a modification to one of the key performance indicators ("KPI") for certain outstanding awards granted pursuant to our Long-term Incentive Compensation Program ("LTIP"). This modification, which is explained in greater detail below as well in the Compensation Discussion and Analysis section of this proxy statement, applies to outstanding LTIP awards for the following performance periods: (i) January 1, 2023 through December 31, 2025 (the "2023 LTIP Awards") and (ii) January 1, 2024 through December 31, 2026 (the "2024 LTIP Awards" and, together with the 2023 LTIP Awards, and as revised by the modification, the "Revised LTIP Awards").

Specifically, the Revised LTIP Awards were amended to replace the Operating EPS KPI with the Core EPS KPI, solely for portions of the applicable performance periods that were not yet complete at the time of the modification. For the 2023 LTIP Awards, the modification applies with respect to Company performance during fiscal 2025, and for the 2024 LTIP Awards, the modification applies with respect to Company performance during fiscal 2025 and fiscal 2026. Accordingly, there was no impact to how LTIP performance was measured with respect to any fiscal year that was complete at the time of the modification. Furthermore, the maximum payout for the cumulative EPS component was modified to be limited to 100% of target for the 2023-2025 and 2024-2026 LTIP cycles.

The Revised LTIP Awards apply to all eligible recipients of the 2023 LTIP Awards and 2024 LTIP Awards, including our named executive officers. As noted above, the Operating EPS KPI ceased to be an appropriate measure of Company performance upon the shift to Core EPS. As such, the Board believed that the Revised LTIP Awards were necessary and appropriate to ensure full alignment between the incentive compensation payable to management, including our named executive officers, and the Company's key business objectives and how we report our financial results to investors.

More specifically, from fiscal 2022 through 2024, our non-core earnings from pension and Signal Peak, which are often volatile and outside of management's control, decreased significantly – by over 50%. This performance is misaligned with the Company's high-quality core earnings performance, which grew by 33% over the same period. As previously disclosed, management believes that Core EPS is a better reflection of the true performance of the regulated utilities that we manage and the necessary corporate functions of the Company. The modifications to the Revised LTIP help to ensure that management continues to be aligned with this key performance metric for the performance periods that followed the shift in reporting from Operating EPS (non-GAAP) to Core EPS.

Please refer to the Compensation Discussion and Analysis section of this proxy statement, as well as our Current Report on Form 8-K filed with the SEC on June 20, 2025, for more information regarding the Revised LTIP Awards.

In circumstances where the Board Chair is not independent, it is the Board's policy, consistent with our Code of Regulations and Corporate Governance Policies, to designate a Lead Independent Director in order to strengthen board independence and performance. When appointed, the Lead Independent Director's responsibilities shall include, but not be limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Serving as principal liaison between and among the Board Chair, President and CEO, the independent directors and management

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Presiding at executive sessions of the independent directors

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Authority to convene meetings of the Board, in consultation with the Board Chair, and of the independent directors

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Authority to attend all committee meetings

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Providing input regarding the Board and committee meeting schedules

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Providing input to the Chair, committee Chairs and management regarding the scope, quality and timeliness of meeting agendas and materials

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪In coordination with the Governance Committee Chair, participating in the process for annual review and evaluation of Board, committee and director performance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Participating in coordination with the Compensation Committee Chair, in the annual evaluation of the performance and compensation of the CEO and other executive members of the Board

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Participating in Board succession planning

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Consulting and directly communicating, as appropriate, with the Company's major shareholders

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Assuming the duties of the Board Chair when the Board Chair is not available to perform his or her duties and otherwise assisting the Board Chair in his or her duties as requested

In addition, the Lead Independent Director is primarily responsible for supporting the independent directors' access to management and, if applicable, leads the independent directors in retaining legal counsel, accountants, industry consultants and other experts to advise the independent directors concerning issues arising in the exercise of their functions.

Your Board schedules regular executive sessions both for your non-management directors and for your independent directors at each regularly scheduled Board meeting, as applicable. Consistent with the Company's Corporate Governance Policies, your Lead Independent Director presides over executive sessions of independent directors.

## Board Composition and Refreshment
Your Board is comprised of individuals who bring unique perspectives and who are highly qualified and independent (other than Mr. Tierney, who is not considered independent because of his employment with the Company). Your Board's succession planning takes into account the importance of Board refreshment and having an appropriate balance of experience and perspectives on your Board.

The Governance Committee reviews Board succession planning on an ongoing basis. In performing this function, the Governance Committee recruits and recommends nominees for election as directors to your Board. Accordingly, your Board has regularly added directors who bring diversity, new ideas and fresh perspectives into the boardroom. All nine nominees have joined the Board after the beginning of 2017, with an average tenure of 5.2 years.

The Governance Committee has authority to retain and engage a third-party search firm to identify a candidate or candidates for the Board.

## Board Oversight of Risk
The Company recognizes both the need to take certain risks in the ordinary course of business as well as the opportunities that may present themselves related to such risks, which together can help to ensure the overall success of the Company. Led by the Chief Risk Officer ("CRO"), the Company has implemented an Enterprise Risk Management process to identify, prioritize, report, monitor, manage and mitigate its significant risks, including strategic, financial, operational, compliance, litigation and reputational risks. An Enterprise Risk Management Committee, chaired by the CRO and consisting of senior executive officers, provides oversight and monitoring to ensure that appropriate risk policies are implemented and effective. The Enterprise Risk Management Committee also vets risk prioritization and mitigation strategies to help ensure that risks are managed in accordance with the Company's expectations. In addition, other management committees address topical risk issues to support the Board's oversight of risk management as discussed below. Timely reports on significant risk issues are provided as appropriate to employees, management, senior executive officers, respective Board committees, and the full Board. The leadership of our risk group provides oversight of day-to-day risk management efforts and prepares enterprisewide risk management reports for presentation to the Audit Committee and your Board.

Your Board administers its risk oversight function through the full Board and its committees, and views risk management as an integral part of the Company's strategic planning process. The Audit Committee charter requires the Audit Committee to oversee the process for identifying, assessing, managing and monitoring enterprise risks, including major financial risks, as well as strategic and operational risks and oversee risks related to the financial statements, payment processes, and financial reporting process and controls, and the regulatory considerations related to cybersecurity. The Audit Committee also reviews and discusses with management the steps taken to monitor, control, and mitigate such exposures.

In addition to the Audit Committee, our other Board committees also play key roles in risk oversight within each of their areas of responsibility. Specifically, the Compensation Committee reviews, discusses and assesses risks related to executive compensation programs, including incentive compensation and equity-based plans, as well as human capital and the relationship between our risk management policies and practices and compensation. See also, "Risk Assessment of Compensation Programs" found in the Compensation Discussion & Analysis ("CD&A") section in this Proxy Statement. The Governance Committee considers risks related to corporate governance, including Board and committee membership, Board effectiveness, related person transactions, the Company's corporate citizenship practices, the Political and Lobbying Action Plan and corporate responsibility strategies and initiatives. The Finance Committee evaluates risks relating to financial resources and strategies, including capital structure policies, financial forecasts, budgets and financial transactions, commitments, expenditures, long- and short-term debt levels, dividend policy, acquisition and divestitures, issuance of securities, exposure to fluctuation in interest rates, share repurchase programs and other financial matters deemed appropriate by your Board. The Operations and Safety Oversight Committee considers risks associated with safety, reliability, cybersecurity, customer service, environmental strategy, protection and sustainability, and the Company's electric distribution, transmission and generation facilities.

Through this oversight process, your Board engages on significant risk issues on a timely basis, including the risks inherent in the Company's strategy. The table below illustrates the Board and Board committees' primary oversight with respect to key risks,

although the complexity of such risks often intersect with each other and/or are also overseen by the full Board. In addition, while the Company's risk group administratively reports to your Senior Vice President, Chief Financial Officer & Strategy, the CRO also has full access to the Audit Committee and is scheduled to attend and report at other Board committee meetings as part of their respective risk oversight responsibilities.

## Evaluating Board Effectiveness
Your Board is committed to a rigorous evaluation process as further described below. Annually, Board, committee and individual director evaluations are performed and coordinated by the Governance Committee. In 2025, through oversight by the Governance Committee and engagement with the Board Chair and Lead Independent Director, your Board engaged an independent third party experienced in Board governance matters to assist in assessing the effectiveness of the full Board, the committees and independent directors.

## Other Governance Practices and Policies
**Code of Conduct** 

FirstEnergy's Code of Conduct, *The Power of Integrity*, lays the foundation for what we expect from all FirstEnergy employees, officers and directors. It reflects our collective commitment to keep integrity at the forefront of everything we do — a pledge underscored by the inclusion of integrity in our mission and core values. By adhering to the expectations of compliance and ethics in this Code, always acting with uncompromising integrity, and speaking up when something doesn't seem right, we are paving the way for a strong future for FirstEnergy.

Any substantive amendments to, or waivers of, the provisions of this document will be disclosed and made available on our website, as permitted by the SEC and as disclosed in our most recent Annual Report. The Code is available, without charge, upon written request to the Corporate Secretary, FirstEnergy Corp., 341 White Pond Dr., Akron, Ohio 44320, and it is accessible on our website at *www.firstenergycorp.com/responsibility*.

**Corporate Governance Policies and Standing Committee Charters** 

Your Board believes that the Company's policies and practices should enhance your Board's ability to represent your interests as shareholders. Your Board established Corporate Governance Policies which, together with Board committee charters, serve as a framework for meeting your Board's duties and responsibilities with respect to the governance of the Company. Our Corporate Governance Policies and Board committee charters are reviewed at least annually and the most current versions are available on our website at *www.firstenergycorp.com/charters*.

**Director Orientation and Continuing Education** 

Your Board recognizes the importance of its members keeping current on company, industry and governance issues and their responsibilities as directors. All new directors participate in orientation soon after being elected to your Board. Also, your Board makes available and encourages continuing education programs for Board members, which include internal strategy meetings and presentations and engagement with relevant third-party experts, third-party presentations and external programs.

**Attendance at Board Meetings, Committee Meetings and the Annual Meeting of Shareholders** 

Our Corporate Governance Policies provide that directors are expected to attend all scheduled Board and applicable committee meetings and the Company's annual meetings of shareholders. Your Board held nine meetings in 2025. The overall attendance percentage for our directors was approximately 94% in 2025, and all directors attended more than 75% of the Board meetings and the meetings of the committees upon which he or she served in 2025. Also, all of our directors who were members of the Board at the time of the 2025 Annual Meeting attended the 2025 Annual Meeting.

Non-management directors met, as annually required, as a group in executive session without the CEO or any other non-independent director or member of management at each of the regularly scheduled 2025 Board meetings. Our Lead Independent Director presided over all executive sessions of independent directors.

**Other Public Company Board Membership and Related Time Commitments** 

Our Corporate Governance Policies provide that directors will not, without your Board's approval, serve on a total of more than four public company boards of directors (including FirstEnergy). Further, without your Board's approval, no director who serves as an executive officer of any public company may serve on a total of more than two public company boards of directors, including FirstEnergy. When a director has a major change in their responsibilities, including principal employment or directorships, but excluding changes resulting from a normal retirement as well as commitments with non-profit organizations, the Governance Committee considers such change and makes any appropriate recommendation to your Board.

**Communications with your Board of Directors** 

Your Board provides a process for shareholders and interested parties to send communications to your Board and non-management directors. As set forth in the Company's Corporate Governance Policies, shareholders and interested parties may send written communications to your Board or a specified individual director, including our Chair of the Board, by mailing any such communications to the FirstEnergy Board of Directors at the Company's principal executive office, c/o Corporate Secretary, FirstEnergy Corp., 341 White Pond Dr., Akron, Ohio 44320. Our Corporate Governance Policies can be viewed by visiting our website at *www.firstenergycorp.com/charters*.

The Corporate Secretary or a member of her staff reviews all such communications promptly and relays them directly to your Board or the appropriate individual director, provided that such communications (i) bear relevance to the Company and the interests of the shareholder, (ii) are capable of being implemented by your Board, (iii) do not contain any obscene or offensive remarks, (iv) are of a reasonable length, and (v) are not from a shareholder who has already sent two such communications to your Board in the last year. Your Board may modify procedures for sorting shareholder communications or adopt any additional procedures, provided that they are approved by a majority of independent directors.

Your Audit Committee also receives, reviews and acts on complaints and concerns regarding accounting, internal accounting controls or auditing matters, including complaints regarding material ethical or criminal misconduct on the part of the Board of Directors, the CEO, any officer reporting directly to the CEO, the Controller & Chief Accounting Officer, and complaints regarding matters that could lead to significant reputational damage to the Company. Complaints or concerns specifically related to such matters may be made directly to your Audit Committee. Correspondence to the Audit Committee should be addressed to the attention of the Audit Committee Chair (c/o Corporate Secretary), FirstEnergy Corp., 341 White Pond Dr., Akron, Ohio 44320.

## Board Qualifications
The Governance Committee recommends Board candidates by identifying qualified individuals in a manner that is consistent with criteria approved by your Board. In consultation with the Board Chair, President and CEO, the Governance Committee and Lead Independent Director search for, recruit, screen, interview and recommend prospective directors to provide your Board with an appropriate balance of knowledge, experience, backgrounds and capability on your Board. Suggestions for potential Board candidates come to the Governance Committee from a number of sources, including third-party search firms, incumbent directors, officers and others. In connection with the Board's active director succession planning, the Governance Committee regularly evaluates the addition of a director or directors with particular attributes while maintaining an appropriate mix of long-, medium- and short-term tenured directors in its succession planning.

The Governance Committee considers suggestions for candidates for membership on your Board, including those recommended by shareholders. Provided shareholders suggesting director candidates have complied with the procedural requirements set forth in the Governance Committee Charter and Code of Regulations, the Governance Committee applies the same criteria and employs substantially similar procedures for evaluating candidates suggested by shareholders for your Board as it would for evaluating any other Board candidate. The Governance Committee will also give due consideration to all recommended candidates that are submitted in writing to the Governance Committee (c/o the Corporate Secretary), FirstEnergy Corp., 341 White Pond Dr., Akron, Ohio 44320, received at least 120 days before the publication of the Company's annual Proxy Statement from a shareholder or group of shareholders owning one half of one percent (0.5%) or more of the Company's voting stock for at least one year, and accompanied by a description of the proposed nominee's qualifications and other relevant biographical information, together with the written consent of the proposed nominee to be named in the Proxy Statement and to serve on your Board.

addition, we have adopted a proxy access right to permit, under certain circumstances, a shareholder or a group of shareholders to include in our annual meeting proxy statement director candidates whom they have nominated. These proxy access provisions in our Code of Regulations provide, among other things, that a shareholder or group of up to 20 shareholders seeking to include director candidates in our annual meeting proxy statement must own, in the aggregate, 3% or more of the Company's issued and outstanding Common Stock continuously for at least three years. Also refer to the "Proposals and Business by Shareholders" section of the "Questions and Answers about the Annual Meeting" below for information regarding nominations under the Company's Code of Regulations.

**Director Nomination Related Agreements** 

On November 6, 2021, your Company entered into a Common Stock Purchase Agreement (the "Blackstone SPA") with BIP Securities II-B L.P., an affiliate of Blackstone Infrastructure Partners L.P. ("Blackstone"), for the private placement of 25,588,535 shares of the Company's common stock. Pursuant to the Blackstone SPA, your Board, among other matters, agreed to appoint Mr. Sean T. Klimczak to stand for election as a director at the 2022 and 2023 Annual Meetings. Following Mr. Klimczak's resignation on February 7, 2024, Blackstone subsequently nominated Heidi L. Boyd to serve as its director appointee. Your Board accepted the nomination, and appointed Ms. Boyd as a director effective February 16, 2024. Ms Boyd was subsequently elected by shareholders as a director at the 2024 Annual Meeting. Your Board has renominated Ms. Boyd to stand for reelection as a director at the 2026 Annual Meeting for a term expiring at the 2027 Annual Meeting.

Summaries of the terms of the Blackstone SPA are provided in the "Certain Relationships and Related Person Transactions" section below.

**Attributes, Experience, Qualifications and Skills of your Board** 

In recruiting and selecting Board candidates, the Governance Committee takes into account the size of your Board and considers a skills matrix to determine whether those skills and/or other attributes qualify candidates for service on your Board. The attributes, experiences, qualifications and skills considered in accordance with Corporate Governance Policies and the Governance Committee Charter for each director nominee led your Board to conclude that the nominee is qualified to serve on your Board.

The high-level overview below depicts some of the attributes, experiences, qualifications and skills of our director nominees the Governance Committee takes into account. It is not intended to be an exhaustive list of each director nominee's skills or contributions to your Board. Also, additional biographical information and qualifications for each nominee is provided in the "Biographical Information and Qualifications of Nominees for Election as Directors" section below and contains information regarding the person's service as a director, principal occupation, business experience along with key attributes, experience and skills. Each of the nominees brings a strong and unique background and skill set to your Board, giving your Board, as a whole, competence and experience in a wide variety of areas necessary to oversee the operations, strategy and governance of the Company.

\*Mr. Williams is not standing for reelection at the 2026 Annual Meeting.

**Board Membership**

The Company and your Board are committed to a policy of inclusiveness and believe that well-assembled boards represent a variety of complementary skills and experiences. The Governance Committee regularly assesses the size and composition of your Board in light of the current operating requirements of the Company and the current needs of your Board. It is also committed to actively seeking out highly qualified candidates of a variety of backgrounds, skills and professional experience and other attributes that contribute in the aggregate to the optimal functioning of your Board to include in the pool from which future Board nominees are chosen. The Company's Corporate Governance Policies also provide further opportunity for board refreshment by requiring directors who reach the age of 72 to tender their resignations to the Board to be effective upon acceptance by your Board.

**Director Independence** 

Your Board annually reviews the independence of each of its members to make the affirmative determination of independence that is called for by our Corporate Governance Policies and required by SEC rules and New York Stock Exchange ("NYSE") listing standards, including certain independence requirements of Board members serving on the Audit Committee, the Compensation Committee and the Governance Committee. The definition used by your Board to determine independence is included in our Corporate Governance Policies and can be viewed by visiting our website at *www.firstenergycorp.com/charters*.

Each year, our directors complete a questionnaire to assist your Board in assessing whether each director meets the applicable independence standards and the related provisions in the Company's Corporate Governance Policies. The Company facilitates this review by examining its records to determine if there were payments made to, or received from, entities in which each non-employee director or immediate family member has a relationship, based on responses to the questionnaires. Subject to the categorical standards approved by your Board and described below, a list of the relevant entities and the amounts the Company paid to or received from those entities is provided to your Board for the non-employee directors. Utilizing this information, the

Governance Committee presents to your Board (i) an evaluation, with regard to each director, whether the director has any material relationship with the Company or any of its subsidiaries; (ii) a recommendation of whether the amount of any payments between the Company and relevant entities could interfere with a director's ability to exercise independent judgment; and (iii) a review of any other relevant facts and circumstances regarding the nature of these relationships, to determine whether other factors, regardless of the categorical standards your Board has adopted or under the NYSE's independence standards, might impede a director's independence. Based on a review of information concerning each of its non-employee directors and the recommendation of the Governance Committee, your Board will affirmatively determine whether a director may be considered "independent."

Your Board recognizes that in the ordinary course of business, relationships and transactions may occur between the Company and its subsidiaries and entities with which some of our directors are or have been affiliated. Our Corporate Governance Policies provide categorical standards to assist your Board in determining what does not constitute a material relationship for purposes of determining a director's independence. Accordingly, the following commercial and charitable relationships will not be considered to be a material relationship that would impair a director's independence: (i) if the director, an immediate family member or a person or organization with which the director has an affiliation purchases electricity or related products or services from the Company or its subsidiaries in the ordinary course of business and the rates or charges involved in the transaction are fixed in conformity with law or governmental authority or otherwise meet the requirements of Item 404(a) Instruction 7 of Regulation S-K, (ii) the aggregate charitable contributions made by the Company to an organization with which a director, an immediate family member or a person or organization with which the director has an affiliation were less than $100,000 in each of the last three fiscal years, or (iii) the aggregate of other payments made by the Company to another entity or organization with which a director, an immediate family member or a person or organization with which the director has an affiliation, or received by the Company from that other entity or organization, were less than the greater of $1 million or 2% of the affiliated company's revenues in each of the last three fiscal years. Notwithstanding the foregoing, the Board will not treat a director's relationship with the Company as categorically immaterial if the relationship otherwise conflicts with the independence requirements set forth in the NYSE listing standards or is required to be disclosed by the Company pursuant to Item 404 of Regulation S-K.

Based on the February 2026 independence review, your Board affirmatively determined that all non-employee director nominees - Heidi L. Boyd, Jana T. Croom, Steven J. Demetriou, Lisa Winston Hicks, Paul Kaleta, James F. O'Neil III and Leslie M. Turner - and current Director Melvin Williams, who is not standing for re-election, are independent pursuant to our Corporate Governance Policies, the rules and regulations of the SEC and the listing standards of the NYSE. Mr. Tierney, as our CEO, is not independent. Furthermore, Mr. John W. Somerhalder II who previously served as the Company's as Executive Vice Chair from March 2021 to May 2022 and Interim President and Chief Executive Officer from September 2022 to May 2023, meets the NYSE independence standards. In all cases, your Board determined that the nature of the business conducted and any interest in an entity in which the applicable director has a relationship were immaterial both to the Company and to the director. Outside of their service as a Company director, none of the Company's independent directors currently provide professional or other services to the Company, its affiliates or any officer of the Company and none of the Company's directors are related to any executive officer of the Company.

The Governance Committee also determined that none of the relationships described above constituted a related person transaction requiring disclosure under the heading "Certain Relationships and Related Person Transactions" in this Proxy Statement. Also, in each case where the director is a current executive officer of another company, any transactions constituted less than one percent of the Company's and the other company's consolidated gross revenues in each of the last three completed fiscal years.

# Items to Be Voted On

---

| | |
|:---|:---|
| Item 1 | Election of Directors <br>**✓** Your Board recommends that you vote FOR all nominees in Item 1 |

---

You are being asked to vote for the following nine nominees to serve on your Board for a term expiring at the annual meeting of shareholders in 2027 and until their successors shall have been elected: **Heidi L. Boyd, Jana T. Croom, Steven J. Demetriou, Lisa Winston Hicks, Paul Kaleta, James F. O'Neil III, John W. Somerhalder II, Brian X. Tierney and Leslie M. Turner.**

The "Biographical Information and Qualifications of Nominees for Election as Directors" section of this Proxy Statement provides information for all nominees for election at the Annual Meeting. The "Board Qualifications" section above in this Proxy Statement provides information relating to your Board's and Governance Committee's review of nominees. Your Board has no reason to believe that the persons nominated will not be available to serve after being elected. If any of these nominees would not be available to serve for any reason, shares represented by the appointed proxies will be voted either for a lesser number of directors or for another person selected by your Board. However, if the inability to serve is believed to be temporary in nature, the shares represented by the appointed proxies will be voted for that person who, if elected, will serve when able to do so.

Pursuant to the Article XII of Company's Amended and Restated Articles of Incorporation, at any election of directors, a nominee shall be elected to your Board only if the votes cast "For" the candidate exceed the votes cast "Against" the candidate; abstentions and broker non-votes shall not be counted as votes "For" or "Against" a candidate and therefore will have no effect. Our Corporate Governance Policies also provide that in an uncontested election of directors (i.e., an election where the only nominees are those recommended by your Board), any nominee for director who receives a greater number of votes cast "Against" his or her election than votes cast "For" his or her election will promptly tender his or her resignation to the Governance Committee following certification of the shareholder vote. The Governance Committee will promptly consider the tendered resignation and will recommend to your Board whether to accept or reject the tendered resignation no later than 60 days following the date of the shareholders' meeting at which the election occurred. In considering whether to recommend acceptance or rejection of the tendered resignation, the Governance Committee will consider factors deemed relevant by the committee members, including the director's length of service, the director's particular qualifications and contributions to the Company, the overall composition of the Board, the reasons underlying the majority against vote, if known, and whether these reasons can be cured, and compliance with stock exchange listing standards and the Corporate Governance Policies. In considering the Governance Committee's recommendation, your Board will consider the factors considered by the Governance Committee and any such additional information and factors your Board believes to be relevant. Your Board will act on the Governance Committee's recommendation no later than at its next regularly scheduled Board meeting.

Your Board Recommends That You Vote **"For" All Nominees in Item 1**. **✓**<br>

| Item 2  | Ratification of the Appointment of the Independent Registered Public Accounting Firm For 2026 <br>**✓** Your Board recommends that you vote FOR Item 2 |

---

You are being asked to ratify the Audit Committee's appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm to examine the books and accounts of the Company for the fiscal year ending December 31, 2026. While our Code of Regulations does not require shareholders to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm, we are submitting the proposal for ratification as a matter of good corporate governance. However, if shareholders do not ratify the appointment, the Audit Committee will reconsider retaining PricewaterhouseCoopers LLP in future years. Even if the appointment is ratified, the Audit Committee, at its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders. A representative of PricewaterhouseCoopers LLP is expected to attend the Annual Meeting and will be available to respond to appropriate questions and will have an opportunity to make a statement if he or she wishes to do so. We refer you to the "Matters Relating to the Independent Registered Public Accounting Firm" section of this Proxy Statement for information regarding services performed by, and fees paid to, PricewaterhouseCoopers LLP during the years 2024 and 2025. Item 2 requires the affirmative vote of a majority of the votes cast and abstentions will have no effect. There can be no broker non-votes on Item 2 as it is considered a "routine" matter under applicable NYSE rules.

Your Board Recommends That You Vote **"For" Item 2**. **✓**<br>

| Item 3  | Approve, on an Advisory Basis, Named Executive Officer Compensation <br>**✓** Your Board recommends that you vote FOR Item 3 |

---

The following proposal provides shareholders the opportunity to cast an advisory, non-binding vote to approve the compensation of the NEOs (a "Say-on-Pay" vote) as further described in the CD&A and the related compensation tables and narrative disclosure. This resolution is required pursuant to Section 14A of the Securities Exchange Act of 1934, as amended. Currently, the advisory vote is held annually. Following the 2026 Annual Meeting, the next advisory vote on NEO compensation is scheduled to occur at the Company's 2027 Annual Meeting of Shareholders. Your Board strongly supports the Company's executive pay practices and asks shareholders to support its executive compensation program by adopting the following resolution:

"RESOLVED, that the shareholders approve, on an advisory basis, the compensation of the FirstEnergy Corp. Named Executive Officers, as such compensation is disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables, and the other related narrative executive compensation disclosure contained in the proxy statement."

The primary objectives of the Company's executive compensation program are to attract, motivate, retain and reward the talented executives, including the NEOs, who we believe can provide the performance and leadership to achieve success in the highly complex energy industry. Our executive compensation program is centered on a pay-for-performance philosophy.

In deciding how to vote on this proposal, we encourage you to read the CD&A for a more detailed discussion of our executive compensation programs and practices applicable to the NEOs, beginning on page 33.

Your Board strongly believes that our compensation philosophy, in conjunction with continued shareholder outreach, is in the best interests of shareholders. We will continue to annually review and evaluate all compensation plans and programs with the goal of aligning such plans and programs with market practice where appropriate and with the best interests of our shareholders. Item 3 is an advisory proposal that requires the affirmative vote of a majority of the votes cast; abstentions and broker non-votes will not be counted as votes "for" or "against" and, therefore, will have no effect.

Although this advisory vote is non-binding, your Board and the Compensation Committee value the views of our shareholders and expect to consider the voting results when considering future executive compensation practices for the NEOs.

Your Board Recommends That You Vote **"For" Item 3**. **✓**<br>

*John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, CA 90278, plans to introduce the following proposal at the Annual Meeting. We have been notified that John Chevedden is the beneficial owner of no less than 90 shares of your Company's common stock. The Company is presenting this proposal and supporting statement as submitted by the proponent. The Company is not responsible for any inaccuracies contained in this shareholder proposal.*

**Proposal 4 — Independent Board Chairman**

![img217999304_79.jpg](img217999304_79.jpg)

Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary in order that 2 separate people hold the office of the Chairman and the office of the CEO as soon as possible.

The Chairman of the Board shall be an Independent Director. A Lead Director shall not be a substitute for an independent Board Chairman.

The Board shall have the discretion to select an interim Chairman of the Board, who is not an Independent Director, to serve while the Board is required to seek an Independent Chairman of the Board on an accelerated basis. This policy could be phased in when there is a contract renewal for our current CEO or for the next CEO transition although it is better to adopt it now. An independent Board Chairman at all times improves corporate governance by bringing impartiality, objective oversight, and external expertise to board decisions, mitigating conflicts of interest, enhancing transparency, and boosting investor confidence.

This detached perspective allows the chairman to focus on shareholder interests, strengthen management accountability, and provide critical checks and balances, ultimately contributing to the Company's long-term sustainability and credibility.

This may be a particularly good time to consider the merits of this proposal.

Numerous news reports from 2025 reflect unfavorably on FirstEnergy, including a lawsuit over its internal investigations into the Ohio bribery scandal and criticism of its energy plans in West Virginia.

News coverage in 2025 frequently links FirstEnergy to its role in the Ohio House Bill 6 political corruption scandal, which involved bribing state officials to pass favorable legislation. FirstEnergy previously paid a $230 million fine to the U.S. government to resolve criminal charges.

News from September 2024 regarding FirstEnergy's settlement with the Securities and Exchange Commission (SEC) over fraud charges related to the bribery scheme also appeared in 2025 news reports. The SEC charged FirstEnergy with defrauding investors and fined the company $100 million for its role in the corruption scandal. FirstEnergy also paid $20 million to settle with the Ohio Attorney General's Office and avoid criminal charges in August 2024.

In October 2025, the Sierra Club issued a press release accusing FirstEnergy of failing to protect customers from rising costs in its 2025 Integrated Resource Plan for its West Virginia subsidiaries. The Sierra Club criticized the plan for not including energy efficiency programs and for continuing to rely on gas-fired generation instead of cheaper, clean solar power.

In July 2025, FirstEnergy reported mixed second-quarter results, falling short on revenue. Yahoo Finance highlighted that FirstEnergy was projected to see a decline in earnings year-over-year.

FirstEnergy continued to receive customer complaints in 2025, according to customer review websites. A review on ConsumerAffairs describes frustration with the process for receiving a refund card and concerns over personal data security.

Please vote yes:

## Your Company's Response — Item 4
The Board recommends a vote AGAINST this proposal for the following reasons:

*FirstEnergy's Governance Framework Already Provides for Robust Independent Board Leadership*

The shareholder proposal requests that the Company adopt an "enduring policy" requiring the roles of Board Chair and CEO to always be held by two separate individuals, with the Board Chair required to be an independent director. When the Board Chair is not independent, it is the Board's policy to designate a Lead Independent Director. Lisa Winston Hicks has served in this role since 2022, providing impartiality, objective oversight and external expertise to Board deliberations, enhancing transparency, and improving investor confidence. Although the proponent asserts that a "Lead Director" is not a substitute for an independent Board Chair, the clearly defined and publicly disclosed responsibilities of the Lead Independent Director offer the same core governance benefits the proponent attributes to an independent Board Chair. These responsibilities, set forth in the Company's Corporate Governance Policies and described on page 9 of this Proxy Statement, provide an effective counterbalance to the Board Chair's leadership and include, among other things:

▪Serving as principal liaison among the Board Chair, President and CEO (whether those roles are combined or separate), the independent directors and management;

▪Presiding at executive sessions of the independent directors;

▪Convening meetings of the Board, in consultation with the Board Chair, and meetings of the independent directors;

▪Providing input to the Board Chair, committee chairs and management regarding the scope, quality and timeliness of meeting agendas and materials; and

▪Participating in the annual evaluation of the CEO's performance and compensation and, if applicable, that of other executive Directors.

Moreover, the Board, upon recommendation of the Governance Committee, conducts a rigorous annual analysis of each director's independence. Our Lead Independent Director, together with the other independent directors and independent Board committees, consistently provide strong, effective oversight of management.

The Company's leadership structure already ensures strong, independent oversight without the rigidity of the one-size-fits-all mandate suggested by the proponent.

*Flexibility in Board Leadership is Essential for Responsible Governance*

It is the Board's philosophy that the roles of Board Chair and the CEO or other executive roles may be filled by the same individual, as circumstances warrant; different leadership structures may be appropriate at different times. The Board believes that it is best positioned to determine which director should serve as its Chair and strongly believes that it must retain the flexibility necessary to determine the most effective leadership structure.

While having separate Board Chair and CEO roles has been appropriate at various points in the Company's history, our independent directors have determined that having a combined Board Chair and CEO coupled with a strong Lead Independent Director is the appropriate Board leadership structure at this time. Specifically, it is Mr. Brian X. Tierney's deep knowledge of the industry, our business, and our stakeholders that makes him the optimal candidate, in the Board's judgment, to work efficiently with the Board in setting and implementing the Company's strategic priorities. At the same time, the Lead Independent Director ensures that independent oversight is consistently and effectively exercised providing appropriate governance guardrails.

Requiring separation of the Board Chair and CEO roles at all times – regardless of future needs – would unnecessarily restrict the Board's ability to exercise its business judgment and could prevent the Board from selecting the leadership structure that best serves the Company and shareholders at the time.

---

*The Shareholder Proposal Relies on Matters Unrelated to Board Leadership Structure*

Much of the proponent's supporting statement cites news items and historical matters that are unrelated to the question of whether mandating an independent Board Chair would improve governance. These citations do not demonstrate that the Company's current governance framework is deficient or that a rigid leadership structure would have led to different outcomes.

To the contrary, the Board regularly evaluates potential governance enhancements, incorporates stakeholder feedback such as that cited by the proponent, and has implemented substantial reforms in recent years. The Company remains firmly committed to transparency, compliance and strong corporate governance practices.

*Conclusion*

The Board agrees that independent oversight is essential to effective governance and appreciates the proponent's perspective on board leadership structure. However, the Board believes that mandating a single, rigid leadership structure is not in the best interests of shareholders. The Company's existing governance framework already provides strong independent leadership and oversight and prescribing a specific leadership model would unduly restrict the Board's ability to exercise its fiduciary duty to act in the best interests of the Company and all shareholders.

**For these reasons, the Board recommends that shareholders vote AGAINST Item 4.**

# E xecutive Compensation

## C ompensation Committee Report
The Compensation Committee reviewed and discussed the CD&A with management and based on such review and discussions, the Compensation Committee recommended to your Board that the CD&A be included (or incorporated by reference, as applicable) in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, and this 2026 Proxy Statement.

Compensation Committee as of December 31, 2025: James O'Neil III (Chair), Heidi Boyd, Steven Demetriou, Lisa Hicks, and Paul Kaleta.

## C ompensation Discussion and Analysis

## Introduction
This CD&A provides an overview of the Company's strategy and performance, shareholder engagement process, 2025 executive compensation programs and decisions, and current expectations for the 2026 executive compensation programs. This CD&A focuses on the compensation of our NEOs for fiscal year 2025, who are as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Named Executive Officer** | **Current Title** |
| &nbsp;&nbsp;**Brian X. Tierney** | Board Chair, President and CEO |
| **K. Jon Taylor** | Senior Vice President, Chief Financial Officer ("CFO") and Strategy |
| **A. Wade Smith** | President, FirstEnergy Utilities |
| &nbsp;&nbsp;**Hyun Park** | Senior Vice President, Chief Legal Officer ("CLO") |
| &nbsp;&nbsp;**Toby L. Thomas** | Chief Operating Officer ("COO") |

---

## Key Executive Officer Transitions and Appointments
**Chair of Board Transition**

On December 18, 2024, the Board appointed Mr. Tierney to serve as Chair of the Board, effective January 1, 2025. Mr. Somerhalder, who served as non-independent Chair of the Board from May 2022 through December 31, 2024, continues to serve on the Board as a director.

## Additional Information about this CD&A
This CD&A uses certain capitalized terms, which are defined in the Glossary of Terms, beginning on page 59. In general, we use the term "CEO" in this CD&A to refer to Mr. Tierney in his role as Board Chair, President and CEO. Mr. Tierney does not receive any incremental compensation for his service as Board Chair. In addition, certain performance incentive metrics discussed in this CD&A and utilized during 2025 in measuring our NEOs' pay-for-performance are based on non-GAAP financial measures. In accordance with SEC rules, the definitions for those metrics in the Glossary of Terms include how these non-GAAP financial measures are calculated from the closest GAAP measure as included in FirstEnergy's audited financial statements. The Compensation Committee (referred to in this CD&A as the "Committee") believes that these non-GAAP metrics, which correspond to and are aligned with key aspects of the Company's financial performance disclosures, best align NEO incentive opportunity with Company performance, which directly supports long-term shareholder value.

## Executive Summary
2025 was a transformational year for FirstEnergy. We executed on our customer-focused growth strategies, delivered a strong financial performance and advanced our transformation into a premier electric company. Recent highlights include:

▪Delivered on all key financial metrics, including Core Earnings per share (non-GAAP) ("Core EPS"), base O&M, capital investments and cash from operations.

▪Deployed $5.6 billion in Energize365 investments, a 25% increase from 2024, supporting improved reliability, resiliency and system performance.

▪Improved reliability for customers by 10% year over year, with strong results in states with commission-approved investment programs.

▪Achieved constructive regulatory outcomes that support future investment and long-term growth.

▪Strengthened governance and risk management, through continued derisking of legacy matters, resulting in upgraded S&P credit ratings, and external recognition for compliance leadership.

▪Returned value to shareholders with total shareholder return of 17.3% in 2025, including dividends. We expect to declare dividends of $1.86 per share in 2026, a 4.5% increase over 2025, pending continued Board approval.

▪Introduced a $36 billion 2026-2030 investment plan that supports customer affordability, reliability and grid resiliency while delivering attractive, low-risk returns.

▪Advanced needed new regulated generation with the February 2026 filing for a 1.2-GW combined-cycle natural gas facility in West Virginia.

▪Positioned for significant long-term transmission investments to support load growth.

▪Improved organizational performance by decentralizing decision-making, strengthening accountability, and bringing 2,500 employees back to the office to enhance collaboration.

**Shareholder Engagement and Say-on-Pay Results** 

Our Board, including the Compensation Committee and Committee chair, together with management are committed to engaging our shareholders routinely and soliciting their perspectives on key performance, compensation and governance issues. Consistent with prior years, with support of select board members, management conducted extensive outreach during 2025. During our outreach, management and your Board did not receive shareholder concerns regarding the Company's 2025 Say-on-Pay vote outcome or general executive compensation matters. The Company continues to design its programs consistent with prior shareholder feedback and best practices.

Our 2025 Say-on-Pay vote successfully passed with over 95% support, which we consider to be a continued strong endorsement of our pay practices and consistent with the vote result of 95% approval on the Company's 2024 Say-on-Pay vote. In an effort to improve the relationship between pay and performance, better tie our executive compensation programs to our business strategies, and drive the right executive behaviors, the Committee continues to regularly assesses the design of our incentive programs.

While we did not make any adjustments to the overall compensation structure for our NEOs based on the 2025 Say-On-Pay vote, the Board approved changes to certain aspects of the STIP and LTIP in 2025 including i) the removal of Baseline O&M as a STIP KPI resulting in Core Earnings (non-GAAP) ("Core Earnings") as our standalone financial KPI in the STIP; ii) simplifying the STIP design, including eliminating the STIP earnings gate and pool of funds to align with market practice; and moving the LTIP from 100% performance-based RSUs, that settled partially in cash and partially in Company stock, to a split of 40% time-based RSUs and 60% performance-adjusted RSUs settling entirely in Company stock, thereby eliminating the cash-based component. These changes are primarily designed to focus on key areas that are essential to achieving our strategic goals.

In February 2025, the Company made a strategic decision to transition away from Operating Earnings (non-GAAP) ("Operating Earnings") and Operating Earnings per share (non-GAAP) ("Operating EPS") to Core Earnings and Core EPS to help investors better assess the performance of our regulated operations. Core Earnings include the results of our four business segments that

management can influence and are reflective of the long-term earnings power of FirstEnergy while excluding special items and contributions of Signal Peak and pension components of earnings that are volatile and outside of management influence. Effective as of the quarter ending March 31, 2025, the Company no longer reported or provided guidance based on Operating EPS and transitioned to reporting and providing guidance on Core EPS. Our investors responded well and appreciated the transparency and focus on our primary businesses. In June 2025, the Board approved a modification to the Operating EPS KPI applicable to the 2025 and 2026 calendar years to certain outstanding awards under the LTIP. This change is consistent with the shift in investor focus and aligns investor and management interests in the 2023-2025 and 2024-2026 LTIP cycle. Of note, in July 2025, the Company sold its remaining interest in Signal Peak, concluding this investment. For more information, refer to the "Goal Changes for LTIP Outstanding Cycles" section below.

**Commitment to Pay for Performance**

Our executive compensation programs is designed to support pay-for-performance practices that reflect shareholder feedback, reinforce our strategic priorities and align with industry best practices, as summarized below.

---

| | |
|:---|:---|
| **Best Practices** | **Actions** |
| **Shareholders want pay-for-performance alignment; metrics should drive Company strategy and long-term shareholder value** | &nbsp;&nbsp;&nbsp;▪Our executive compensation programs link pay to key drivers of shareholder value:<br>&nbsp;&nbsp;&nbsp;&nbsp;▪LTIP payouts for the 2023-2025 cycle were tied to the Company achieving certain levels of earnings per share (non-GAAP) and Relative TSR, both of which are strong indicators of shareholder value in the utility industry; <br>&nbsp;&nbsp;&nbsp;&nbsp;▪In February 2025, the Company shifted investor focus from Operating EPS to Core EPS; <br>&nbsp;&nbsp;&nbsp;&nbsp;▪The 2023-2025 cycle was a combination of Operating EPS from January 2023 through December 31, 2024, and Core EPS from January 1, 2025, through December 31, 2025;<br>&nbsp;&nbsp;&nbsp;&nbsp;▪Since changes were made mid-cycle for the 2023-2025 LTIP, the Operating EPS/Core EPS payout was capped at target performance; and<br>&nbsp;&nbsp;&nbsp;&nbsp;▪External segment reporting is consistent with FirstEnergy's internal financial reports to regularly assess performance of the business and allocate resources.<br>▪Our LTIP includes a TSR cap on the performance-adjusted RSUs (if absolute TSR is negative over the three-year LTIP period, the payout will be capped at 100%).<br>▪All STIP and LTIP payouts remain capped at 200%, based on the Committee's analysis of market practices and to further align your Company's incentive programs with those of our peers. |
| **Shareholders prefer a majority of LTIP to be performance-based** | &nbsp;&nbsp;&nbsp;▪For 2025, the Committee maintained a majority of performance-based awards in our LTIP (60% performance-based RSUs). |
| **Shareholders prefer three-year cumulative vs. successive annual performance periods for the long-term incentive plans** | &nbsp;&nbsp;&nbsp;▪For 2025, the performance-based component of LTIP consisted of: <br>&nbsp;&nbsp;&nbsp;&nbsp;▪Three-year cumulative goals focused on Core EPS (65% weighting) and three-year Relative TSR measured against the S&P 500 Utility Index (35% weighting); and <br>&nbsp;&nbsp;&nbsp;&nbsp;▪An absolute TSR cap. |
| **Goals need to be set rigorously and the process needs to be transparent** | &nbsp;&nbsp;&nbsp;&nbsp;▪Our goals and goal ranges undergo a rigorous independent assessment and are set to: <br>&nbsp;&nbsp;&nbsp;&nbsp;▪Align pay opportunity with performance;<br>&nbsp;&nbsp;&nbsp;&nbsp;▪Be reasonable and competitive; and<br>&nbsp;&nbsp;&nbsp;&nbsp;▪Encourage stretch-level performance throughout the entirety of the measurement period. As an example, in the 2025 STIP, to achieve maximum payout on our financial KPI, we required performance that aligned with the upper end of fiscal year 2025 guidance as disclosed in February 2025. |
| **STIP and LTIP metrics should be relevant to the business and not overlapping** | &nbsp;&nbsp;&nbsp;▪The 2025 STIP included financial Core Earnings, operational goals, safety goals, and employee engagement goals to help drive our business strategy and corporate objectives.<br>▪The performance-based component of the 2025 LTIP incorporated three-year cumulative Core EPS growth and Relative TSR goals to reward achievement of longer-term goals and drive shareholder value. |

## Governance of our Execu tive Compensation Programs
**Compensation Philosophy** 

The primary objectives of our executive compensation programs are to:

▪Attract, retain, focus and reward our talented and experienced executive team who drive our success in the highly complex utility industry by offering overall competitive total compensation;

▪Reflect our collective commitment to ensuring that we conduct business with integrity, help all employees do the right thing and treat our coworkers and communities with the respect we all deserve;

▪Promote the long-term financial health of the business and the creation of value for the sustained benefit of shareholders by emphasizing long-term performance-based incentives in the pay mix;

▪Calibrate pay for performance to help ensure that the interests of our executives and shareholders are aligned, such that 50<sup>th</sup> percentile compensation is realized for strong corporate performance, above 50<sup>th</sup> percentile compensation is realized for exceptional performance, and below 50<sup>th</sup> percentile compensation is realized for below expected performance;

▪Tie executive awards to corporate results as well as overall business unit performance to hold executives accountable for their areas of responsibility;

▪Recognize individual contributions, including individual performance, experience and future potential in determining actual pay levels to help ensure that the Company retains its most critical talent; and

▪Conduct ourselves in a way that comports with standards of good governance consistent with creating long-term value for shareholders while encouraging a culture of inclusion.

**Role of our Compensation Committee, Management and Compensation Consultant** 

The Committee is responsible for overseeing executive compensation and making recommendations to the Board for establishing appropriate salary and incentive compensation for our executive officers, which includes our NEOs. The Committee oversees executive compensation in accordance with our compensation philosophy, which is designed to align our executives' interests with Company and business unit performance, business strategies and corporate objectives and drivers of growth in shareholder value, while reflecting our commitment to ethical conduct in all that we do. In this process, the Committee evaluates information provided by its independent compensation consultant, Farient Advisors LLC ("Farient"), and our CEO, as discussed below. The Committee reviews the mix and level of compensation by each component individually and in the aggregate. The Committee, using tally sheets and accumulated wealth summaries, also reviews current and previously awarded but unvested compensation.

Management continually works to help ensure that high-performing leaders within the Company are appropriately recognized and considered during succession planning discussions. The Company's talent philosophy is that all leaders, regardless of level, must demonstrate the ability to motivate future performance, be accountable for their behaviors and results, deliver results and enable employees to do their best every day. Executive succession is reviewed periodically by the CEO, the CHRO, and the Committee. Executive succession plans are reviewed by the Committee, as applicable, and with the full Board annually. With respect to our CEO's compensation, each year the Committee:

▪Reviews, determines and recommends to the Board the Company's pay-related goals and objectives and

▪Makes compensation recommendations to the Board for its approval or ratification based upon the CEO's performance and competitive market data provided by our independent consultant.

The Committee and Board are responsible for establishing the compensation of the Company's executive officers, including the NEOs, as well as certain other senior leaders. Neither the CEO nor any other NEO makes recommendations for setting his or her own compensation. The recommendation of the CEO's compensation is determined in Committee meetings during an executive session and is presented to the non-management members of your Board for review and approval. Annually, the Committee also reviews the goals and targets of the incentive compensation programs with a focus on setting challenging, but realistic, targets to drive performance and continuous improvement to improve shareholder value over the long term.

The CEO, with input from Human Resources and the Lead Independent Director, typically makes recommendations to the Committee with respect to the compensation of the other NEOs. The CEO possesses insight regarding individual performance, experience, future promotion potential, and intentions in retaining particular senior executives, including NEOs. Farient, as discussed below, regularly provides market-level commentary and observations regarding compensation adjustments to the Committee, with the decision for adjusting compensation ultimately residing with the Committee.

The Committee regularly evaluates the needs of the Committee and the services provided by the independent consultant. From time to time, the Committee will conduct a request for proposal process to appoint or re-appoint, as appropriate, the independent consultant. In 2025, the Committee completed a request for proposal and review and reappointed Farient.

Farient provided independent advice with respect to executive and director compensation and related corporate governance matters. The Committee relies on Farient's expertise in benchmarking and familiarity with competitive compensation practices in the utility and general industry sectors. In addition, the Committee regularly requests advice from Farient concerning the design, communication and implementation of our incentive compensation plans and other programs. However, all decisions as to executive compensation design and amounts ultimately rest with the Committee and the Board, as applicable.

The services provided by Farient to the Committee in 2025 included:

▪Review of our compensation philosophy, including the alignment of our executive compensation practices with our compensation philosophy and assessing potential changes to address trends in market practice and shareholder expectations;

▪Review of our peer groups used for compensation benchmarking purposes for executives and directors;

▪Independent review and assessment of the rigor of incentive compensation performance goals and the goal setting process, including:

oEvaluating historical and projected performance;

oReviewing analyst estimates to understand external expectations;

oAnalyzing historical and projected peer data; and

oCalculating the probability of achievement of targets to assess the rigor of goals.

▪Analysis of competitive compensation practices, policies and levels for executives and directors within our peer groups, including the STIP and LTIP designs;

▪Review of the description of our executive compensation practices in our annual proxy statement;

▪Regularly informing the Committee of legislative and regulatory changes, market trends and current issues with respect to executive compensation, and educating the Committee on our processes, plans and programs, including review of the

FirstEnergy Corp. Second Amended and Restated Executive Compensation Recoupment Policy and the FirstEnergy Corp. Compensation Clawback Policy and alignment with competitive practice and regulatory requirements; and

▪Preparation for and attendance at all Committee meetings, including executive sessions, if applicable and as needed.

The Committee considered representations from Farient that they were an independent consultant and that they had no conflicts of interest. The Committee assessed the independence of Farient, as required by SEC and NYSE rules and requirements. The Committee also considered and assessed relevant factors that could give rise to a potential conflict of interest with respect to Farient and their work. Based on this review, the Committee is not aware of any conflict of interest that has been raised by the work performed by Farient.

**Benchmarking** 

The Committee uses competitive benchmarking data to evaluate compensation practices and develop compensation recommendations for each of the NEOs. The Company uses a combination of a utility peer group and a general industry peer group to determine an overall competitive total rewards package. **Employee and executive compensation, executive benefits and perquisites, broad-based benefits (retirement benefits, death benefits, long-term disability and health care) and director compensation are all benchmarked against the same peer groups.** The Committee uses competitive "blended" market data (i.e., the average of the revenue-regressed 50th percentile of our utility peer group and general industry peer group, referred to as the "Blended Median") to assist in determining any compensation adjustments and assess the competitiveness of base salary, short- and long-term target incentive opportunities and total target compensation. The Committee considers 80% to 120% of the Blended Median for each component of pay, and in total, to be a competitive range for any covered individual.

For 2025, the general industry peer group was comprised of companies that are both larger and smaller than FirstEnergy by revenue size. The median revenue of the utility and general industry peer groups is aligned with FirstEnergy's revenue of approximately $12.7 billion in 2025. The 2025 peer groups were based on the following criteria:

**Compensation Mix** 

We review our compensation philosophy, pay mix and pay vehicles for our NEOs annually to help ensure that our pay program structure and elements support our strategy and align with shareholder interests. Under our compensation design, the percentage of pay that is based on performance generally increases as a NEO's responsibilities increase, with our CEO's target pay having the potential to vary the most among our NEOs. Approximately 60% of our CEO's total target pay and 53% of our other NEOs' average target pay is variable. Variable pay could be reduced to zero if performance metrics are not met at a minimum threshold level.

The charts below illustrate the pay mix, which includes the variable pay mix for our NEOs, based on each NEO's annualized 2025 total target pay levels as described in the "Target Compensation (Base Salary + Target Incentive Compensation)" section below. For all NEOs, the values shown are effective as of December 31, 2025.

![img217999304_100.jpg](img217999304_100.jpg)

## Target Compensation (Base Salary + Target Incentive Compensation)
In December 2024, the Committee reviewed a competitive benchmarking analysis prepared by Farient. This report assessed each then-serving NEO's compensation levels and mix against the Blended Median. Based on this analysis, in February 2025, the Committee determined to maintain base salary and target STIP, LTIP and total target compensation for all NEOs, except as otherwise indicated in the table below. The amounts reflected in the below table continue to align with the Blended Median.

For 2025, target opportunities continued to be set at or near the Blended Median of our peer groups. As of December 31, 2025 (except as otherwise noted), target compensation levels for the NEOs on an annualized basis were as follows:

(1) As explained further below, our LCE KPI was either a 0% or 200% payout.

(2) For each of the NEOs, all LTIP awards, if earned, are paid in stock.

(3) Represents target value determined by the Committee based on annualized base salary and target opportunity percentages. Amounts do not necessarily correspond to the amounts shown in the "Stock Awards" column of the Summary Compensation Table due to SEC rules regarding Summary Compensation Table disclosure, nor to the amounts that may ultimately be realized by our NEOs.

The maximum payout under the STIP and LTIP is 200% and 160% of an individual's target opportunity, respectively. Our 2025-2027 cycle of LTIP is 60% performance-based RSUs and 40% time-based RSUs. The NEOs may earn nothing under the STIP, earn a minimum of 40% of their opportunity under the LTIP given the time-based component, receive payments that are below their target opportunities for the performance-based incentive awards if the Company falls short of its pre-established goals, or earn

above their target opportunities for the performance-based incentive awards if the Company performs above its pre-established goals. Except in limited circumstances, the Committee may use discretion to make adjustments to awards.

## Incentive Compensation Programs
Shareholders previously approved the 2020 Incentive Compensation Plan (the "Incentive Compensation Plan") in May 2020. The purpose of the Incentive Compensation Plan is to promote the success of FirstEnergy by permitting the grant of incentives to certain employees that link their professional responsibilities to both short-term performance to key metrics and the long-term financial success of your Company to increase shareholder value, providing for various types of awards including equity-based and cash-based awards. Integrity is the foundation of our incentive compensation philosophy and reflects our collective commitment to ensuring that we conduct business ethically with honesty, humility and accountability.

As outlined above in the "Role of our Compensation Committee, Management and Compensation Consultant" section, the Committee, with support from Farient, conducted its annual goal rigor analysis to establish the goal ranges for the 2025 STIP and LTIP awards. In setting the goals, the Committee considered prior year results, company performance, investor expectations, and strategic accomplishments for the year and over the long-term, on both a relative and absolute basis. The Committee expects goals that are realistic but challenging and that drive improved performance from year to year.

**STIP**

The STIP provides annual cash awards to executives whose contributions support the achievement of your Company's identified financial and operational KPI goals, which are linked to the Company's business strategy and corporate objectives. The Committee annually reviews the goals and targets with a focus on setting challenging but realistic targets that are intended to drive operational performance and shareholder value.

**KPIs and Weightings for STIP** 

The Committee annually establishes the KPIs under the STIP that must be satisfied for a NEO to receive an award and recommends that the Board approve the relative weightings for each KPI with respect to each participating NEO. The Committee recommended, and the Board approved, the following design elements for the 2025 STIP:

▪Maintained the stretch (maximum) payout opportunity level at 200% of target to remain consistent with market practices;

▪Aligned with peer practices by removing the Baseline O&M component and focusing on Core Earnings, which served as our only financial STIP KPI, as distinguished from the LTIP cumulative Core EPS KPI;

▪Maintained the weighting of safety metrics at 15% in the STIP to promote our core value of safety, including the weightings of DART Rate and LCEs each at a 7.5% weighting in 2025;

oThreshold and target performance levels for the LCE KPI were removed. Instead, the KPI was set to pay out at stretch level (200%) for zero LCEs or no payout (0%) if one LCE occurs anywhere across the FirstEnergy footprint;

▪Increased the weighting of the Operations Index to 20% and maintained the Employee Engagement Survey KPI goal at 5%;

▪Simplified the STIP design to align better with market practice by eliminating the earnings gate and pool of funds, given the move to Core Earnings as the single financial KPI; this KPI will be paid based on actual performance; and

▪Maintained a threshold payout starting at 50% and stretch at 200% for all non-Financial KPIs and a threshold payout starting at 25% and stretch at 200% for the Financial KPI of Core Earnings. There is no payout for any KPIs that fall below threshold.

The Committee reviewed, and the Board approved, the STIP performance metrics and weightings for each of the NEOs in February 2025. For 2025, the NEOs had the following metrics and weightings.

**2025 STIP Performance Goals**

Threshold, target and stretch levels are established for the KPIs based on Core Earnings and achieving continuous improvement in safety and operational performance. Management and the Committee strive to set challenging and achievable goals and establish all threshold, target and stretch STIP goals at equal or more rigorous levels compared to the prior year, whenever practicable. In 2025, the threshold, target and stretch levels under the STIP for the NEOs were (dollars in millions):

**LTIP**

Beginning with the 2025-2027 cycle, the Committee approved moving from 100% performance-based RSUs, which settled partially in cash and partially in Company stock, to 60% performance-adjusted RSUs and 40% time-based RSUs, each designed to pay out entirely in Company stock, thereby eliminating the cash-based component of the LTIP grants. These changes better align our plan design to our utility peers.

The performance-adjusted RSUs will continue to vest based on the achievement of two metrics: Cumulative Core EPS, weighted at 65% and Relative TSR, weighted at 35%. Cumulative Core EPS threshold award opportunity begins with a threshold payout of 25% and a maximum payout of 200%. Relative TSR threshold award opportunity begins if our performance is at the 25th percentile, while stretch awards, with a maximum payout of 200%, begins at the 85th percentile. Relative TSR continues to be measured against the S&P 500 Utility Index for the 2025-2027 cycle. Payouts are capped at 100% of target if our absolute TSR is negative over the three-year performance period. These performance measures support continued financial improvement and increase focus on earnings across the Company's regulated businesses while creating a direct line of sight for executives to drive shareholder value and evaluate the overall performance against our peers in the utility industry. The time-based RSUs granted in the 2025-2027 cycle will vest on March 1, 2028, based on employees' continued service. Unlike the performance-adjusted portion, there is no impact from performance on the time-based RSUs.

Overall, the total LTIP opportunity for the 2025-2027 cycle can range from 40% to 160%. The chart below defines the KPI measures applicable to the 2025 LTIP grants. This LTIP design applied to all NEOs in 2025. Additional details regarding the 2025-2027 LTIP grants are provided in the narrative following the "Grants of Plan-Based Awards in Fiscal Year 2025" table.

The Board approved the LTIP grants for the NEOs at its meeting on March 19, 2025. The grant date for the 2025 performance-adjusted and time-based RSUs was March 19, 2025. Each participating NEO's target LTIP award opportunity is divided by the average of the high and low prices of the Company's common stock on the grant date to determine the number of performance-adjusted and time-based RSUs awarded. In addition, the Committee approved a discretionary performance component, which includes a modifier to the value at grant that may be adjusted upward or downward by up to 15%. The modifier is intended to further underscore the importance of each leader maintaining a strong focus on performance and our core values and behaviors. No adjustments were made to the 2025-2027 LTIP grants for our NEOs.

(1) Relative TSR is calculated over the three-year performance period as compared against the S&P 500 Utility Index and will be based on a continuous function between the 25th and 85th percentile up to a maximum of 200% payout. The Relative TSR target payout aligns with the 50th percentile.

(2) If the Company's absolute TSR is negative for the three-year cumulative performance period of 2025-2027, the LTIP awards will be capped at a target opportunity level of payout (100%).

## Goal Changes for LTIP Outstanding Cycles
On June 17, 2025, upon recommendation of the Committee, the Board approved a modification to the Operating EPS KPI applicable to certain outstanding LTIP awards for the 2025 and 2026 calendar years. Effective as of the quarter ending March 31, 2025, the Company no longer reported or provided guidance based on Operating EPS and transitioned to reporting and providing guidance on Core EPS. For the applicable years, this change replaces the Operating EPS KPI with the Core EPS KPI for the 2023-2025 and 2024-2026 LTIP cycles. In addition, the Board approved limiting the maximum payout for the cumulative EPS component at 100% of target for these LTIP cycles.

These changes aligned these performance cycles and the overall LTIP program with the Company's transition to assessing performance based on Core Earnings rather than Operating Earnings, as reflected in the company's 2025 earnings guidance provided to investors in February 2025.These changes are applicable to all eligible participants of the 2023 and 2024 LTIP grants, which include the CEO and all other NEOs.

Your Board believes that this modification was appropriate and benefits participants and shareholders as it:

▪Is completely consistent with your Company's 2025 and 2026 earnings guidance and the transition of your Company's external reporting to shareholders from Operating EPS to Core EPS;

▪Is simple to understand;

▪Serves to align the incentive compensation payable to management based on Core Earnings performance starting in 2025, consistent with the Company's earnings guidance;

▪Does not apply retroactively to performance for any completed fiscal year at the time of Board modification (i.e., 2023 and 2024 results); and

▪Will better reflect the performance of our management team.

In addition, the 2025 LTIP metrics reflect Core EPS and relative TSR for consistency with external reporting and the modified 2023 and 2024 LTIP design.

Prior to this adjustment, the 2023-2025 and 2024-2026 LTIP cycles were comprised of two financial performance KPIs: Cumulative Operating EPS (weighted at 65%) and Relative TSR (weighted at 35%). This change does not impact the measurement of

**2023-2025 LTIP Cycle Payout**

Our incentive structure measures actual performance against threshold, target and stretch goals based on three-year cumulative and average goals over the performance period. The 2023-2025 LTIP was initially granted and comprised of the following two performance measures: Cumulative Operating EPS (weighted at 65%) and Relative TSR (weighted at 35%). As noted above, on June 17, 2025, upon recommendation of the Committee, the Board approved a modification to the Operating EPS KPI, replacing it with the Core EPS KPI for the 2025 calendar year portion of the 2023-2025 (and 2024-2026) LTIP cycle. Additionally, the Board approved limiting the maximum payout for the cumulative EPS component at 100% of target.

FirstEnergy's average stock prices with reinvested dividends for December 2025 of $50.51 was greater than the average stock price in December 2022 of $41.67. As a result, the absolute TSR cap does not apply and the 2023-2025 cycle of performance-adjusted RSUs was paid as earned as reflected in the table below.

Based on the results of the two KPI measures, the Committee recommended, and independent members of the Board approved the payout at 81% of target payout opportunity for our participating NEOs. Upon his hire in June 2023, Mr. Tierney was granted prorated stock-based performance-adjusted RSUs based on his annual salary and total LTIP target opportunity and a proration factor for 33 out of 36 months for the 2023-2025 LTIP cycle. Upon his hire in December 2023, Mr. Smith was granted prorated stock-based performance-adjusted RSUs based on his annual salary and total LTIP target opportunity and a proration factor for 27 out of 36 months for the 2023-2025 LTIP cycle. Upon his hire in November 2023, Mr. Thomas was granted prorated stock-based performance-adjusted RSUs based on his annual salary and total LTIP target opportunity and a proration factor for 28 out of 36 months for the 2023-2025 LTIP cycle. In March 2026, the performance-adjusted RSUs granted in 2023 were paid in shares of our common stock and cash respectively as follows: Mr. Tierney: 153,278 shares and $3,889,141; Mr. Taylor: 44,687 shares and $1,133,576; Mr. Smith: 22,855 shares and $578,942; Mr. Park: 25,771 shares and $656,755; and Mr. Thomas: 16,067 shares and $412,285.

## 2026 Incentive Plan Design and NEO Compensation
For 2026, our approach towards incentive plan design is that each individual STIP KPI should be set based on its alignment with strategic priorities and planned actions for 2026, ensuring measurable progress toward our goal of becoming a premier electric utility. In February 2026, your Board approved several changes to the STIP, particularly around our safety and operational KPIs designed to: align to our strategy; align with industry peers; support our key objectives in 2026; and encourage the right behaviors. Our financial KPI, Core Earnings, will not change following the updates made in 2025 to maintain transparency and comparability to peers, as this change better reflects performance we control and provides employees with a better line of sight to focus on what they can influence. To align STIP with our focus on high-energy safety training, the two safety KPIs will be Systemwide Serious Injury or Fatality (SIF) and Systemwide High-Energy CMVA Rate. These metrics will replace Systemwide DART and Systemwide LCEs as the industry continues to move towards more leading indicators that are focused on high-energy hazards. The Operations Index will be replaced by seven individual components focused on operational excellence designed to emphasize our commitment to reliability for our customers. We will continue to maintain SAIDI, TOF and Regulated Generation EFOR as metrics from the prior Operations Index while adding: Inoperable Equipment, Percentage Reliability Investment, Blue Sky Customer Average Interruption Duration Index (CAIDI), and Substation SAIDI. For the Employee Engagement KPI, we will continue to use the Employee Engagement survey.

Consistent with the design changes made for the 2025 LTIP grants, the 2026 LTIP grants covering the 2026-2028 award cycle, will continue to be comprised of 40% time-based RSUs and 60% performance adjusted stock-based RSUs, each of which will settle entirely in Company stock. We will maintain a weighting of 65% Core EPS and 35% Relative TSR, with the absolute TSR cap on the performance-based awards if our TSR is negative over the three-year performance period. The individual performance modifier will be maintained for the 2026-2028 cycle. The modifier may be used to adjust the LTIP value at grant upward or downward by up to 15% within the limits of the total targeted cost of LTIP plan. No individual performance adjustments were made to the 2026-2028 LTIP grants for our NEOs.

For 2026, target opportunities continue to be set at or near the Blended Median of our peer groups. The 2026 target compensation levels for the continuing NEOs are as follows:

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;**Executive** | **2026 Base<br>Salary Rate** | **2026 STIP (as a %<br>of Base Salary)** | **2026 LTIP (as a %<br>of Base Salary)** |
| &nbsp;&nbsp;**Brian X. Tierney** | $1500000 | 150% | 683% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**K. Jon Taylor** | $910000 | 90% | 325% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A. Wade Smith** | $780900 | 80% | 250% |
| &nbsp;&nbsp;**Hyun Park** | $789495 | 75% | 225% |
| &nbsp;&nbsp;**Toby L. Thomas** | $661500 | 70% | 225% |

## Other Compensa tion Policies and Practices
**Retirement Benefits** 

We offer retirement benefits to our NEOs through our qualified plan, the FirstEnergy Corp. Master Pension Plan, and our executive nonqualified plans, under Article VI of the FirstEnergy Corp. Amended and Restated Executive Deferred Compensation Plan ("EDCP") and the FirstEnergy Corp. Cash Balance Pension Restoration Plan ("Cash Balance Restoration Plan"). The qualified plan benefit historically has been based on earnings, length of service, and age at retirement and is considered a defined benefit plan

under the Internal Revenue Code of 1986, as amended. For NEOs hired or rehired on or after January 1, 2014, the qualified plan benefit uses a cash-balance formula based on age and service. The qualified plan benefit is subject to applicable federal and plan limits. The EDCP and Cash Balance Restoration Plan are designed to provide a benefit to the NEOs that is competitive and comparable to that for our general employee population.

In recognition of Mr. Park's extensive legal expertise, first-hand experience dealing with crisis situations, utility industry knowledge and compliance focus, as well as to incentivize him to join the Company and to encourage retention, at the time of his hire, we agreed that Mr. Park would be provided an additional credit of $275,000 into the Cash Balance Restoration Plan after five years of continuous employment, which occurred in January 2026. For more information, refer to the "Pension Benefits as of December 31, 2025" table on page 67. Retirement benefits for the NEOs are further discussed in the narrative section following the Pension Benefits table later in this proxy statement.

**EDCP (Elective Deferrals)** 

NEOs may elect to defer a portion of their compensation into the EDCP. They may defer 1% to 50% of base salary to a cash retirement account; 1% to 85% of STIP awards to either a cash or stock account; and 1% to 85% of LTIP awards to a stock account. The EDCP offers NEOs the opportunity to accumulate assets denominated both in cash and in Company common stock, on a tax-favored basis. Beginning in 2017, any deferral elections to a cash or stock account made by a NEO will ultimately be paid only in cash based upon the NEO's distribution elections.

Earnings on deferrals in the EDCP stock accounts of NEOs track FirstEnergy shares. Earnings on deferrals into the cash retirement accounts of NEOs were credited at the Moody's Corporate Long-term Bond Yield Index rate plus 3% for funds deferred prior to 2013 and the Moody's Corporate Long-term Bond Yield Index rate plus 1% for funds deferred in 2013 and later. Any above-market earnings for 2025 are included in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column of the SCT.

**Personal Benefits and Perquisites**

The Company provides perquisites designed to recruit and retain key executive talent while remaining aligned with peer practices. The Board has determined that our NEO perquisites are appropriate for these purposes and are not excessive.

In 2025, our NEOs could use the corporate aircraft for limited personal use. With CEO approval, select executives, including the NEOs, may from time to time use corporate aircraft for personal travel, which may include family travel. We have a written policy that sets forth guidelines regarding the personal use of corporate aircraft by executive officers and select executives in accordance with the IRS regulations and customary compensation practices. FirstEnergy's executive relocation program provides reimbursement or payment for relocation-related expenses, including travel, temporary living expenses, new home closing costs, home sale assistance, and gross-up on certain relocation benefits for estimated federal, state and FICA taxes on expenses which are not tax deductible. The Committee believes the foregoing perquisites are reasonable, competitive, and consistent with our overall compensation philosophy.

In March 2025, as disclosed in the 2025 Proxy Statement, the Board approved two new perquisites, Executive Physicals and Executive Wealth Services, for select executives of the Company including our NEOs. In February 2026, the Board approved Cleveland Clinic Concierge Medicine Program for select executives, including the NEOs, as an enhancement and complement to the Executive Physical perquisite approved in 2025. The program is a premium, membership-based primary care model designed to provide executives with highly personalized and proactive medical care. While the Company assumes the annual cost of these programs (only in the event the executive chooses to utilize the service), it is treated as imputed income to the executive, where applicable.

**Severance and CIC Benefits**

On September 23, 2025, after a thorough review process by the Board and the Committee, with input and advice from Farient, the Board, upon recommendation by the Committee, approved (i) amendments and restatements of the FirstEnergy Executive Severance Benefits Plan (the "Executive Severance Plan") and the FirstEnergy Corp. 2017 Change in Control Severance Plan (the "CIC Plan" and, together with the Executive Severance Plan, the "Plans"), and (ii) new CIC provisions for the 2026-2028 cycle of

performance-adjusted RSU award agreements (the "Performance-Adjusted RSU Award Agreements") and time-based restricted stock unit award agreements (the "Time-Based RSU Award Agreements" and, together with the Performance-Adjusted RSU Award Agreements, the "RSU Award Agreements"), in each case to be effective January 1, 2026. The Board's approval of the amended and restated Plans and the new provisions of RSU Award Agreements modernizes and aligns the Company's executive severance compensation program with peer practice.

**Executive Severance Plan**

The Executive Severance Plan provides severance benefits to eligible executives who are involuntarily separated by the Company due to the sale or closing of a facility, corporate restructuring, merger, acquisition, reduction in the workforce, or job elimination (collectively, "Qualified Separations by the Company"). Benefits under the Executive Severance Plan are also offered if an eligible executive terminates his or her employment with the Company because a new job assignment would result in the occurrence of any one or more of the following events: (i) 15% or greater reduction in the executive's then current base salary (except with respect to across-the-board salary reductions to similarly-situated Company employees); (ii) the distance from the executive's current residence to his or her new reporting location being at least 50 miles farther than the distance between such executive's current residence and previous reporting location (collectively, "Qualified Separations by the Executive" and, together with Qualified Separations by the Company, "Qualified Separations" and each, a "Qualified Separation").

Prior to the amendment and restatement, the CEO was not included in the Executive Severance Plan; accordingly, had an involuntary separation without cause occurred during 2025, the CEO's severance benefits, if any, would have been determined by the Committee, in its discretion, and approved by the independent members of the Board. Additionally, prior to the amendment and restatement, the cash severance benefits under the Executive Severance Plan were calculated using a service-based formula (the "Service-Based Formula"), such that, in the event of a Qualified Separation, an eligible executive was entitled to receive three weeks of base salary for each full year of service (with a minimum benefit of 52 weeks of base salary and a maximum benefit of 104 weeks of base salary). As amended and restated, the Executive Severance Plan includes the CEO as an eligible participant and provides that cash severance benefits (collectively, the "Amended Severance Benefits") will be determined as follows in the event of a Qualified Separation:

▪The CEO, all officers (as defined by Rule 16a-1(f) of the Exchange Act), and any remaining members of the Company's Executive Council will be entitled to severance pay equal to one and one-half times such participant's base salary;

▪Presidents, Vice Presidents and equivalents, will be entitled to severance pay equal to such participant's annual base salary.

▪Director-level executives will be entitled to severance pay based upon the Service-Based Formula, such that an eligible executive will be entitled to receive three weeks of base salary for each full year of service (with a maximum benefit equal to such participant's annual base salary).

Notwithstanding the foregoing, the amended and restated Executive Severance Plan provides that eligible executives, as defined therein, will be entitled to receive severance benefits based upon the prior Service-Based Formula as of December 31, 2025, if such amount is greater than the amount that the executive would receive under the Amended Severance Benefits.

Additionally, under the amended and restated Executive Severance Plan, for an executive with a Qualified Separation who is eligible for and elects continuation of health care and/or dental care under COBRA, the Company will waive a portion of the COBRA premium for a period equal to the lesser of (i) 18 months following the date of the Qualified Separation and (ii) the date that such executive ceases to qualify for COBRA coverage.

An executive's receipt of any severance benefits under the amended and restated Executive Severance Plan is contingent upon such executive's timely execution and delivery of a valid and irrevocable separation agreement in the form provided by the Company that contains, among other provisions, a general release and waiver of claims in favor of the Company and related persons and entities, confidentiality, return of property and non-disparagement provisions (a "Release") and (ii) the Release becoming irrevocable no later than 60 days following the executive's separation from the Company. Severance amounts will be paid in a lump sum as soon as administratively possible after the Release is effective, but no later than two and one-half months after the date that the Qualified Separation occurs.

**CIC Plan** 

The CIC Plan provides for severance benefits in the event that an eligible executive experiences a termination of employment (either without "Cause" by the Company or for "Good Reason" by the executive (each as defined in the CIC Plan)) within the 24 month period following a change in control of the Company. Participants in the CIC Plan are not permitted to receive severance benefits under the CIC Plan and another Company severance plan, program or arrangement.

Prior to the amendment and restatement, all participants were eligible for the same level of benefits under the CIC Plan, which included (collectively, the "Change in Control Benefits"):

▪Cash severance (the "Change in Control Cash Severance") equal to two-times the sum of the executive's (i) base salary and (ii) target award under the Company's STIP;

▪Payment of the annual STIP for the fiscal year in which the termination occurs, paid at target and prorated for the number of days that the executive worked during such fiscal year;

▪Continued health and welfare coverage for two years; and

▪Up to $30,000 of outplacement services for the one-year period following the change in control.

The Change In Control benefits under the amended and restated CIC plan remain the same for all eligible participants, except in the case of the CEO, who under the amended and restated CIC Plan, will be entitled to Change in Control Cash Severance equal to two and ninety-nine hundredths (2.99) times the sum of the CEO's (i) base salary and (ii) target award under the STIP.

The "Change in Control" definition in the amended and restated CIC Plan was revised to conform to the corresponding definition in the Company's 2020 Incentive Compensation Plan (the "2020 ICP") to ensure consistency and for ease of administration in the event of a change in control. Additionally, the CIC Plan required the Board to conduct an annual review of the CIC Plan to determine whether the term of the CIC Plan should be extended for an additional one-year period. The amended and restated CIC Plan will automatically renew for successive one-year terms, unless otherwise terminated by action of the Board.

An executive's receipt of any benefits under the amended and restated CIC Plan is contingent upon such executive's execution and non-revocation of a general release and waiver of claims in favor of the Company and related persons and entities. Cash amounts under the amended and restated CIC Plan will be paid in a lump sum within 60 days of the executive's termination of employment.

**CIC Provisions in the RSU Award Agreements**

As noted above, the Board approved new provisions of the RSU Award Agreements for grants of performance-adjusted RSUs and time-based RSUs made on or after January 1, 2026. The new provisions of the 2026-2028 cycle of Performance-Based RSU Award Agreement provides that, in the event of a Change in Control, outstanding unvested performance-based RSUs will vest at target level of performance, to the extent such RSUs are not replaced with a Replacement Award. The new provisions of the 2026-2028 cycle of Time-Based RSU Award Agreement provides that outstanding unvested time-based RSUs will vest in full upon a Change in Control (as defined in the 2020 ICP) to the extent such RSUs are not replaced with a "Replacement Award" (as defined in the 2020 ICP).

**Share Ownership Guidelines for Executives**

We believe it is critical for the interests of executives and shareholders to be clearly aligned. Therefore, the Committee maintains share ownership guidelines to promote meaningful stock ownership by our executives, including our NEOs. Your Company not only wants executives to meet their required share ownership levels to build an ownership mentality and demonstrate commitment to aligning their interests with shareholders, in a timely manner. These guidelines specify the value of Company shares that our participating executives must accumulate within five years of becoming an executive officer. Additionally, executives who are not on track to meet their required share ownership levels or have failed to achieve required share ownership levels within the five-year

compliance period may be subject to the following consequences imposed at the discretion of the Committee, subject to approval by the Board:

▪Reduce or eliminate the annual STIP award opportunity (as necessary) and consider replacement with a discretionary stock award; and/or

▪Require executives to purchase sufficient shares to meet their required share ownership levels.

Each participating executive is required to retain all Company shares earned under equity grants or purchased or accumulated until the executive meets his or her share ownership guidelines. The specific share ownership guidelines are based on a multiple of an executive officer's base salary, with the higher multiples applicable to the executives having the highest levels of responsibility.

The share ownership multiples for the NEOs who were executive officers as of December 31, 2025 were as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Current Executive Officers** | **Share Ownership Multiple** |
| &nbsp;&nbsp;**Brian X. Tierney** | 7X base salary |
| **K. Jon Taylor** | 4X base salary |
| **A. Wade Smith** | 3X base salary |
| &nbsp;&nbsp;**Hyun Park** | 3X base salary |
| &nbsp;&nbsp;**Toby L. Thomas** | 3X base salary |

---

Unvested performance-adjusted RSUs and time-based RSUs granted under the LTIP are not counted as eligible shares for executives to meet their share ownership requirements. The following types of holdings apply toward the share ownership guidelines:

▪Shares directly or jointly owned in certificate form or in a stock investment plan, including 60% of any unvested restricted stock;

▪Shares owned through the FirstEnergy Corp. Savings Plan;

▪Shares held individually or jointly by a broker, or in certain circumstances, held in trust, or in an IRA; shares held by a spouse, or other beneficially owned shares, to the extent known by the Company; and

▪Units deferred pursuant to the EDCP.

As of December 31, 2025, Messrs. Taylor, Smith and Park had met their share ownership requirements. With the March 1, 2026 LTIP vesting, Mr. Tierney had met his share ownership requirements. Mr. Thomas had not yet met his share ownership requirements, but has until November 30, 2028, to do so. Share ownership guidelines do not drive the establishment of compensation levels. The Committee reviews previously granted awards, both vested and unvested, that are still outstanding on a regular basis.

**Anti-Hedging and Pledging Policies** 

We prohibit our employees (including officers) and directors from engaging in hedging or monetizing transactions that would allow them to own Company securities without the full risks and rewards of ownership, including economic exposure to potential decreases in the market value of Company securities.

Your Company has adopted formal policies as part of its insider trading compliance policy regarding securities transactions (the "Insider Trading Practice"), which includes policies regarding hedging practices. The following categories of "Covered Persons" are covered by our Insider Trading Practice:

▪All of the Company's non-employee directors;

▪All officers (including NEOs) and employees of the Company and its affiliates and subsidiaries; and

▪Any other persons that the Company determines should be covered, such as contractors, consultants and professional advisors who have access to material nonpublic information.

---

In addition to the Insider Trading Practice applying to Covered Persons, the following are also covered by our Insider Trading Practice:

▪The portfolio manager and other individuals who can trade in (or make changes in investments in) Company Securities for the Covered Persons;

▪The Covered Persons' Related Persons (except family members who do not reside with a Covered Person — unless such family member confers with the Covered Person when making investment decisions in Company Securities or is directed, influenced or controlled by the Covered Person with respect to transactions in Company Securities); and

▪Any entities that the Covered Persons influence or control.

For these purposes, we consider "Related Persons" of a Covered Person to be their family members and others who reside with them, and any family members who do not live with them but whose transactions in Company Securities are directed, influenced or controlled by them. In addition, "Company Securities" broadly includes all securities of the Company and of its direct and indirect subsidiaries, including but not limited to common stock, options, preferred stock, convertible debentures or other debt securities, and warrants (as well as derivative securities not issued by the Company or its subsidiaries, such as exchange-traded put or call options or swaps relating to any of the foregoing securities).

The Insider Trading Practice generally prohibits a Covered Person from engaging in certain transactions regarding Company Securities owned by them or that they beneficially own, but the Insider Trading Practice does not apply to transactions in Company Securities where such transactions are not initiated by the Covered Person or approved by them, or are not subject to their influence or control (such as mutual fund transactions in Company Securities). More specifically, the prohibition on pledging, hedging or other monetization transactions for Covered Persons explicitly covers a number of possible transactions:

▪Company directors and Company "officers" (under Exchange Act Rule 16a-1(f)) are prohibited from engaging in short-term opposite-way trading within a six-month period; and

▪Covered Persons are prohibited from engaging in short sales, trading in market-based put and call options or other non-compensatory derivative securities, or engaging in specific hedging and monetization transactions, such as prepaid variable forward contracts, equity swaps, collars and exchange funds.

In addition, under the Insider Trading Practice, certain "Designated Insiders" (Company directors, Company "Executive Officers" under Exchange Act Rule 3b-7, Company "officers" under Exchange Act Rule 16a-1(f), members of the Company's Executive Council, members of its disclosure committee and certain other employees with regular access to financial information or otherwise as identified from time to time by the Company) are prohibited from holding Company Securities in a margin account, pledging Company Securities as collateral for a loan, or placing standing or limit orders on Company Securities that remain effective after the day on which they are placed (apart from Company-authorized Rule 10b5-1 trading plans). Other Covered Persons may place standing or limit orders on Company Securities that remain effective after the day on which they are placed, but only for short durations and in a manner that complies with Company restrictions and procedures set forth in the Insider Trading Practice (such as pre-clearance procedures).

**Clawback Policies** 

Your Company has a clawback policy called the FirstEnergy Corp. Second Amended and Restated Executive Compensation Recoupment Policy (its "Discretionary Clawback Policy"), that covers all current or former executive officers, Section 16 officers and other selected executives. In 2019, the Committee approved enhancements to the Discretionary Clawback Policy to continue the previously existing clawback provisions in the event of a financial restatement of the Company, and to include clawback provisions in the event of certain other detrimental activity, as defined in the Discretionary Clawback Policy, resulting in significant operational, financial or reputational harm to the Company as determined in good faith by the Committee. In the event that the Company is required to file a financial restatement due to material noncompliance with financial reporting requirements under U.S. securities laws, regardless of misconduct or contribution to the restatement requirement, the clawback policy allows for recoupment of incentive-based compensation granted, vested or accrued after January 1, 2014, and during the three-year period preceding the filing of the accounting restatement, to the extent such compensation received exceeded what would have been received based on the corrected data relating to the restatement. In the event of significant or material operational, financial or reputational harm resulting from an executive's detrimental activity, the Committee may direct the Company to recoup from such executive

---

incentive-based compensation granted, vested or accrued in an amount as reasonably determined by the Committee in good faith. The Discretionary Clawback Policy is available on the Company's website at www.firstenergycorp.com/charters.

In 2023, the NYSE adopted new listing standards addressing policy requirements for the mandatory recovery of executive incentive-based compensation by issuers with securities listed on the exchange. Following the adoption of these NYSE listing standards, the Board and Committee, respectively, undertook a dual policy approach in which the Board would adopt a new policy specifically for purposes of complying with the new rules, called the FirstEnergy Corp. Compensation Clawback Policy (the "SEC Compliant Clawback Policy"), and the Committee would also revise the Discretionary Clawback Policy consistent with the new rules, as outlined below.

The SEC Compliant Clawback Policy applies only to the Company's current and former Section 16 Officers and requires recovery of excess compensation erroneously awarded to the executive on or after October 2, 2023, in the event of an Accounting Restatement, as defined therein. The SEC Compliant Clawback Policy applies to compensation received during the three-year period preceding the date an accounting restatement is deemed to be required. The SEC Compliant Clawback Policy does not allow Committee discretion to pursue recovery, except in limited circumstances.

Section 16 Officers remain subject to the Discretionary Clawback Policy in that the Committee may, in its discretion, seek recovery of compensation from a Section 16 Officer in the event of detrimental activity. Effective October 1, 2023, the Committee amended the Discretionary Clawback Policy to clarify that there can be no double recovery when recoupment is sought as the result of an accounting restatement pursuant to the SEC Compliant Clawback Policy. The Discretionary Clawback Policy was also amended to align the accounting restatement triggers with those set forth in the SEC Compliant Clawback Policy such that non-Section 16 members of Executive Council may also be subject to a recoupment demand in the event of an accounting restatement, though such demand may be made at the Committee's discretion. Recoupment under the Discretionary Clawback Policy will continue to be at the discretion of the Committee.

**Risk Assessment of Compensation Programs** 

Enterprise Risk Management ("Risk") regularly conducts an independent assessment of the non-financial metrics identified as KPIs for STIP, and their weightings and measurements as deemed appropriate. Risk participates in the discussions regarding the appropriateness of these measures with metric owners and leadership. Risks associated with the Company's compensation policies, practices and programs are managed by a suite of reviews conducted by various management teams, including Risk, Internal Audit, Human Resources and Legal, in connection with Farient's annual goal rigor analysis which focuses on the financial metrics identified as KPIs for STIP and LTIP. At the request of the Committee, Farient also completed an independent risk assessment to ensure that the Company's compensation programs align with our pay-for-performance compensation philosophy without encouraging excessive risk-taking. The purpose of these reviews is to ensure that the Company's compensation programs align with our pay-for-performance compensation philosophy without encouraging excessive risk-taking. Specifically, management seeks to incent employees to perform at a high level and align our executives' interests with our shareholders' long-term interests while simultaneously balancing our shareholders' concerns and discouraging excessive risk-taking. In this regard, the Company's compensation structure contains various features intended to mitigate such risk. These features include, among others:

▪The compensation structure is designed to link an appropriate portion of compensation to the Company's long-term performance

▪The periodic benchmarking of the compensation programs and overall compensation structure is used to evaluate the Company's programs as compared to market practices

▪Annual incentive compensation is based on multiple, diversified, company-based performance metrics, none of which

are applicable to individual executives or small groups of employees, and all of which are consistent with our long-term goals

▪Internal controls and standards of ethics and business conduct are well-established and support our compensation goals and mitigate compensation risk in various ways. We employ various auditing processes on a regular basis in an effort to assure compliance with these controls and standards and

▪The Committee, comprised entirely of independent directors, oversees your Company's compensation policies and practices and is responsible for reviewing, approving and, where appropriate, recommending Board approval for executive compensation (including base salary, incentive metrics, goals and targets), annual incentive compensation programs applicable to senior management, employees, and other compensation plans as appropriate

Farient concluded that the risks associated with the Company's compensation policies and practices are not reasonably likely to have a material adverse effect on the Company. The Company's management team has determined with the support and alignment with Farient, that our compensation programs do not encourage undue risk taking. We have implemented a strong governance structure and compensation plan design features that mitigate overall risks. Accordingly, no material changes or adjustments were made to our compensation programs in light of the aforementioned risk assessment. The Company will continue to monitor its compensation policies and practices to determine whether its risk management objectives are being met with respect to incentivizing its employees, and future compensation program modifications will continue to be reviewed with management, Farient, the Committee and Board to ensure such modifications do not promote excessive risk taking.

For additional information regarding your Company's risk management process and your Board's role in risk oversight, see the related discussion in the "Corporate Governance and Board of Directors Information" section of this proxy statement.

**Insider Trading Practice** 

As noted above, your Company has adopted the Insider Trading Practice, which applies to directors, officers, employees and other covered persons, as well as the Company itself. We believe that the Insider Trading Practice is reasonably designed to promote compliance with insider trading laws, rules and regulations with respect to the purchase, sale and/or other dispositions of the Company's securities, as well as the applicable rules and regulations of the NYSE. A copy of the Insider Trading Practice is filed as Exhibit 19 to the Company's Annual Report on Form 10-K.

**Equity Award Grant Practices**

The Company does not currently grant new awards of stock options, stock appreciation rights, or similar option-like instruments. Accordingly, the Company has no specific policy or practice on the timing of awards of such options in relation to the disclosure of material nonpublic information by the Company. In the event the Company determines to grant new awards of options or option-like instruments, the Board and the Committee will evaluate the appropriate steps to take in relation to the foregoing.

**RSUs (Restricted Stock Units):** An equity vehicle commonly used in long-term incentive programs to reward employees and promote ownership within the Company. RSUs represent the right to receive future delivery of actual stock or cash subject to vesting restrictions (service-based and/or performance-based).

**Relative TSR (Relative Total Shareholder Return):** The total return of a stock to a shareholder for our Company measured against the total return of stock for other companies within a selected peer group. The calculation is based on a set period (e.g., three years) and assumes that dividends are reinvested over this period. Relative TSR is a common performance measure used within long-term incentive plans and helps to align executive payouts to shareholder value creation.

**SAIDI:** Distribution System Average Interruption Duration Index is the average total duration of outage minutes in a year for each customer served adjusted for major storms.

**TOF:** Transmission Outage Frequency measures the transmission line frequency of outages (total number of transmission circuit outages divided by average number of circuits) on 100kV to 500kV circuits after adjustment for major events (Six Sigma). Transmission circuit outages are defined as any loss of flow, momentary or sustained, that is a result of an automatic switching operation. Scheduled outages, emergency forced outages, and operational outages are excluded from the calculation.

**TSR (Total Shareholder Return):** A measure of stock price appreciation and dividend payments over a period of time.

(1) The amounts set forth in the "Stock Awards" column for 2025 represent grants of performance-adjusted RSUs and time-based RSUs, made under the 2020 ICP at the aggregate grant date fair value calculated in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 718 "Stock Compensation" and are based on target amounts. The assumptions used in determining values for 2025 are reflected in Note 5 of the Notes to the Consolidated Financial Statements of the Company's Annual Report on Form 10-K filed with the SEC on February 18, 2026. The grant date fair value at the maximum payout level for each of the NEOs for the 2025 LTIP awards would be as follows: Mr. Tierney: $14,717,379; Mr. Taylor: $4,084,607; Mr. Smith: $2,729,074; Mr. Park: $2,477,227; and Mr. Thomas: $1,945,580. The value of these awards are not payable to the NEO, if at all, until the vesting date or other qualifying event shown in the Outstanding Equity Awards at Fiscal Year-End 2025 table or the 2025 Post-Termination Compensation and Benefits table described later in this proxy statement.

(2) The amounts set forth in the "Non-Equity Incentive Plan Compensation" column for 2025 were earned under the 2025 STIP and paid in the first quarter of 2026.

(3) The amounts set forth in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column for 2025 reflect the aggregate increase in actuarial value to the NEOs of all defined benefit and actuarial plans (including supplemental plans) accrued during the year and above-market earnings on nonqualified deferred compensation. The disclosure assumes 5.59% (qualified pension), 5.41% (nonqualified supplemental pension) and 4.37% (nonqualified cash balance restoration plan) are the discount rates for the present value obligation calculations. The change in values for the pension plans for 2025 are as follows: Mr. Tierney: $115,314; Mr. Taylor: $388,492; Mr. Smith: $55,524; Mr. Park: $67,944; and Mr. Thomas: $39,068. The change in pension value is heavily dependent on the discount rate and mortality assumptions and does not represent the actual value of the change in pension benefit accrued by the NEO during the year. The formula used to determine the above market earnings equals 2025 total interest multiplied by the difference between 120% of the Long-Term Applicable Federal Rate (AFR) and the plan rate and divided by the plan rate. The above market earnings on nonqualified deferred compensation for 2025 are as follows: Mr. Taylor: $53,496; and Mr. Thomas: $460.

a) The value of matching Company contributions under the FirstEnergy Corp. Savings Plan.

b) The value of Company contributions to the NEOs' Health Savings Accounts or FirstEnergy Corp. Savings Plan or cash.

c) The value of charitable matching contributions for 2025. The Company provides a dollar-for-dollar match, up to $5,000 annually, of employee contributions to qualified nonprofit organizations and educational institutions.

d) Premiums for all NEOs covered under the group personal excess liability insurance policy in 2025.

e) Employer cost for basic life insurance premiums in 2025.

f) The value of the personal use of corporate aircraft is calculated based on the aggregate variable operating costs to the Company, including fuel costs, trip-related maintenance, universal weather-monitoring costs, on-board catering, landing/ramp fees, and other miscellaneous variable costs. Fixed costs that do not change based on usage, such as pilots' salaries, the amortized costs of the aircraft, and the cost of maintenance not related to trips are excluded. NEOs' spouses and immediate family members may accompany NEOs on Company aircraft using unoccupied space on business flights that were already scheduled, and the Company incurs no aggregate incremental cost in connection with such use.

g) Effective for 2025, the Committee approved executive wealth and executive physical services perquisite. The value shown in this column represents the cost to the Company for any NEO who utilized these benefits and was prorated for use during 2025, where applicable. These services are treated as imputed income and applicable taxes are deducted from the participating NEO's paycheck.

(5) The amounts set forth in the "SEC Total Without Change In Pension Value and Nonqualified Deferred Compensation Earnings" column differ substantially from, and are not a substitute for, the amounts required to be reported in the Total column pursuant to SEC regulations. We are presenting this supplemental column to illustrate how the Committee views the annual compensation elements for the NEOs. The column adjusts the amount reported in the Total column, as determined under applicable SEC rules, by subtracting the value reported in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column to show how year-over-year changes in these values impact total compensation. The change in pension value amount reported in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column does not reflect current compensation and represents the present value of an estimated stream of payments to be made following retirement. The methodology used to report the change in pension value under applicable accounting rules is sensitive to external variables such as assumptions about life expectancy and changes in the discount rate determined at each year end, which are functions of economic factors and actuarial calculations that do not relate to the Company's performance and are outside of the control of the Committee.

(1) In accordance with FASB ASC Topic 718, the effective grant date for the 2025 performance-adjusted and time-based RSUs granted under the 2025 LTIP is March 19, 2025.

(2) In accordance with SEC rules, the dates set forth in the "Board Action Date" column for these awards represent the date your Board took action to grant the awards.

(3) The amounts set forth in the "Estimated Possible Payouts Under Non-Equity Incentive Plan Awards" columns reflect the potential payouts for each NEO under the 2025 STIP based upon the achievement of KPIs described in the CD&A. The amounts reported in this column were calculated using annualized STIP target opportunity levels as a percent of base salary.

(4) The amounts set forth in the "Estimated Future Payouts Under Equity Incentive Plan Awards" columns reflect the threshold, target and maximum potential payouts for each NEO for the performance-adjusted RSUs granted under the 2025 LTIP, based upon the achievement of the performance measures described in the CD&A. The target amounts are reported in the Stock Awards column of the Summary Compensation Table. If the threshold level of performance is not achieved for the performance-adjusted RSUs, no payout will be made.

(5) The amounts set forth in this column reflect the time-based RSUs granted to each NEO under the 2025 LTIP.

(6) The grant date fair value was computed in accordance with FASB ASC Topic 718 and is also reported in the "Stock Awards" column of the Summary Compensation Table. The performance-adjusted RSUs component is valued based on a Monte-Carlo simulation of $38.246 for the Core EPS portion of the 2025 performance-adjusted RSUs and $26.966 for the Relative TSR portion of the 2025 performance-adjusted RSUs. The time-based RSUs component is valued based on the average high and low stock price of $39.715 on the date of grants.

(1) The awards set forth in the "Grant Type" columns of this table include time-based restricted stock awards, performance-adjusted RSUs and time-based RSUs. Performance-adjusted RSUs generally will vest, in whole or in part, or be forfeited at the end of a three-year performance period to the extent certified by the Committee and independent members of your Board, as further described in the CD&A and Grants of Plan-Based Awards narrative section of this proxy statement. Time-based RSUs will vest, in whole, assuming continuous service. Assuming that the underlying performance conditions are met, the vesting dates for the performance-adjusted RSUs are as follows: 2023 performance-adjusted RSUs – stock-based and cash-based (March 1, 2026); 2024 performance-adjusted RSUs – stock-based and cash-based (March 1, 2027); and 2025 performance-adjusted RSUs and time-based RSUs (March 1, 2028).

(2) The 2023 performance-adjusted RSUs (stock-based and cash-based) included in this column are deemed to be earned because the performance condition has been achieved, but such performance-adjusted RSUs had not vested as of December 31, 2025. The number of shares set forth in this column is based on actual performance of 81% for the 2023 performance-adjusted RSUs (stock-based and cash-based).

(3) The number of shares set forth in both the "Number of Shares or Units of Stock That Have Not Vested" and the "Equity Incentive Plan Awards: Number of Unearned Shares, Units or Other Rights That Have Not Vested" columns include all dividends or dividend equivalents earned and reinvested through December 31, 2025, rounded up to the nearest whole unit or share.

(4) The values set forth in both the "Market Value of Shares or Units of Stock That Have Not Vested" and the "Equity Incentive Plan Awards: Market or Payout Value of Unearned Shares, Units or Other Rights That Have Not Vested" columns are determined by multiplying the number of shares or units by our common stock closing price of $44.77 on December 31, 2025.

(5) Stock awards in this column include unearned performance-adjusted RSUs (at the target amount) for which the performance period has not ended.

(6) Mr. Tierney's restricted stock award was granted on June 1, 2023, to help replace the economically equivalent value he forfeited from his previous employer and vests in equal amounts over a four-year period from the date of grant.

(7) Mr. Taylor's restricted stock award was granted on March 1, 2023, to recognize exceptional performance and criticality of his role and vests over a four-year period with 25% of the award vesting after two years from the date of grant, another 25% vesting after a third year, and the remaining amount vesting after the fourth year.

(8) Mr. Smith's restricted stock award was granted on December 18, 2023, to help replace the economically equivalent value he forfeited from his previous employer and vests in equal amounts over a three-year period from the date of grant.

**Pension Benefits**

**Qualified and Nonqualified Plans**

We offer qualified and nonqualified pension plans to provide retirement benefits to our NEOs. We pay the entire cost of these plans. Retirement benefits from the qualified plan provided under the FirstEnergy Corp. Master Pension Plan ("Master Pension Plan") are calculated using pensionable earnings up to the applicable federal and plan limits. The Master Pension Plan was amended to provide a cash-balance formula for all employees hired or rehired on or after January 1, 2014. In conjunction with the new cash-balance formula, the Company adopted a new nonqualified supplemental plan ("Cash Balance Restoration Plan"), which provides a benefit, based upon the cash-balance formula, to eligible executives hired or rehired on or after January 1, 2014, but without the restriction of federal limits that apply under the qualified pension plan. Mr. Taylor was hired prior to January 1, 2014, and is subject to the traditional supplemental pension formulas discussed below. Messrs. Tierney, Smith, Park and Thomas were hired after January 1, 2014, and are subject to the cash-balance formula discussed below.

**Traditional Supplemental Pension Plan:** The traditional supplemental plan provided under the EDCP provides a benefit based upon the formula used in the qualified plan for pre-2014 hires but is calculated using all pensionable earnings without the restrictions of federal and certain plan limits. Based on the applicable formula of the plan under which the NEO is a participant, the retirement benefit from the qualified and nonqualified plans for pre-2014 hires will be the benefit determined using one or more of the following three formulas:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Career Earnings Benefit Formula: A fixed (2.125%) factor is applied to the executive's total career earnings to determine the accrued (age 65) career earnings benefit. Pensionable earnings under the career earnings formula generally include base salary, annual incentive awards and other similar compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Adjusted Highest Average Monthly Base Earnings Benefit Formula: The benefit is equal to the sum of A and B where A is the highest average monthly base earnings ("HAMBE") times the sum of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪1.58% times the first 20 years of benefit service

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪1.18% times the next 10 years of benefit service

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪0.78% times the next 5 years of benefit service

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪1.10% times each year of benefit service in excess of 35 years

and B is an amount equal to 0.32% times number of years of service (up to 35 years) times the difference between the HAMBE and the lesser of 150% of covered compensation or the Social Security Wage Base, except that B cannot be less than zero.

The HAMBE for the qualified plan are the highest 48 consecutive months of base earnings the executive had in the 120 months immediately preceding retirement or other termination of employment. Pensionable earnings under the qualified plan HAMBE formula generally include base salary and deferred compensation of base salary after 2004. The pensionable earnings under the nonqualified plan HAMBE formula are the same as the qualified plan described above except that deferred compensation of base salary excluded under the qualified plan and annual incentive awards that are paid or deferred are included. Covered compensation represents the average (without indexing) Social Security Taxable Wage Base in effect for each calendar year during the 35-year period that ends when the executive reaches the Social Security normal retirement age.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Final Average Total Pay ("FATP") Formula: The pension benefit under FATP is calculated by determining the HAMBE, multiplying this amount by a fixed factor (1.2%) and then multiplying it by the number of years of Benefit Service at the time of separation or retirement. This amount is then divided by 12 to determine the accrued and vested monthly pension benefit amount.

Under the Master Pension Plan provisions for pre-2014 hires, normal retirement is at age 65 and the completion of five years of eligibility service. The earliest retirement is at age 55 if the employee has at least 10 years of eligibility service. Mr. Taylor will become eligible when he turns 55 in 2028, and subject to the FATP early retirement reduction table. The earliest retirement age without reduction for the qualified plan is age 60 with the exception of those covered under the FATP plan. The earliest retirement age without reduction for FATP is age 62.

Under the Master Pension Plan provisions for pre-2014 hires, the accrued benefits vest upon the completion of five years of service. The benefits generally are payable in the case of a married employee in the form of a qualified spouse 50% joint and survivor annuity or in the case of an unmarried employee in the form of a single life annuity. Unmarried employees can designate a non-spouse beneficiary to receive up to a 100% joint and survivor annuity depending upon the non-spousal beneficiary's age. For the married employee, there also is an option to receive the benefit as a joint and survivor annuity with or without a pop-up provision or a period certain annuity. The annuity provides a reduced monthly benefit, payable to the employee until death. If a joint and survivor annuity is chosen, the employee's named beneficiary will receive 25%, 50%, 75%, or 100% of the employee's benefit based on the employee's and the beneficiary's ages and the elected percentage to be continued after the employee's death. Under the pop-up provisions, the monthly payment to the employee "pops-up" to the single life annuity amount if the beneficiary predeceases the employee. The period certain annuity provides a reduced benefit for the life of the employee and continues the benefit to the named beneficiary for a guaranteed period if the employee's death occurs before the end of the 5, 10 or 15-year period, as elected. No further payments are made if the employee's death occurs after the end of the elected period.

**Cash Balance Formula and Cash Balance Restoration Plan:** The Cash Balance Restoration Plan is a non-qualified plan providing certain key employees hired or rehired on or after January 1, 2014, with a benefit that is generally equal to the benefit that the participant would have been eligible to receive under the cash-balance formula of the qualified Master Pension Plan but for certain federal limitations.

Participants in the cash-balance formula of the Master Pension Plan receive a benefit amount based on a hypothetical account balance that is credited with Pay Credits and Interest Credits. A Pay Credit is credited annually and is equal to a percentage of the participant's eligible compensation. Pensionable earnings include base salary, plus the following amounts paid within any specified period commencing on or after January 1, 2014: overtime pay; bonuses paid pursuant to a formal bonus program; annual incentives or cash sales incentive awards paid prior to termination of service; annual incentives that are earned after December 31, 2013, but deferred under a non-qualified plan; sales commissions; and lump sum merit awards. On December 31st of each year, the participant's age (years and months) plus years of service (years and months) are added together to determine "points." The participant's points are used to determine the applicable Pay Credit percentage for the participant for that year, as shown in the chart below.

---

| | |
|:---|:---|
| **Points (age + service)** | **Pay Credit** |
| Less than 40 points | 4% |
| 40 - 49 points | 5% |
| 50 - 59 points | 6% |
| 60 - 69 points | 7% |
| 70 - 79 points | 8% |
| 80+ points | 9% |

---

An Interest Credit is applied annually to a participant's prior year account balance and is based on the 30-Year Treasury rate from November of the prior year.

A cash-balance participant will vest in their Master Pension Plan benefit after three years of eligible service. Regardless of the vested participant's age at separation from service, the participant will have the option to defer or immediately commence their pension benefit at separation from service. Available forms of payment for the cash-balance portion of the Master Pension Plan include: Single Life Annuity, 50% Joint & Survivor Annuity, 75% Joint & Survivor Annuity, 100% Joint & Survivor Annuity and lump sum distribution. The Cash Balance Restoration Plan benefit is paid as a lump sum benefit as of the date of termination. Early reduction factors do not apply.

If the vested participant elects to defer the payment of the cash-balance benefit under the Master Pension Plan, annual Interest Credits will continue to apply until the participant elects to commence. If a vested participant dies before commencing benefits, a death benefit is generally payable to the participant's surviving spouse or other beneficiary.

Effective as of their hires, Messrs. Tierney, Smith, Park, and Thomas are participants in the cash-balance formula of the Master Pension Plan and in the Cash Balance Restoration Plan. As of December 31, 2025, Messrs. Tierney, Smith and Thomas are not eligible for a pension benefit until the completion of three years of eligibility service.

The compounded annual rate of return on stock accounts was 17.3%, which includes dividends. The amounts set forth in the Aggregate Earnings in Last FY column include above-market earnings which have been reported in the Summary Compensation Table for 2025 as follows: Mr. Taylor: $53,496; and Mr. Thomas: $460.

(3) The amounts set forth in the "Aggregate Balance at Last FYE" column include amounts reported in the Summary Compensation Tables in prior years as follows: Mr. Taylor: $3,028,227; and Mr. Thomas: $13,197. Messrs. Tierney, Smith and Park did not have an outstanding balance as of December 31, 2025.

**EDCP**

The EDCP is a nonqualified deferred compensation plan which provides for the voluntary deferral of compensation. Our NEOs may defer up to 50% of base salary, up to 85% of STIP awards and up to 85% of LTIP awards.

Two investment options are available under the EDCP. NEOs may direct deferrals of base salary and STIP awards to an annual cash retirement account, which accrues interest. The interest rate changes annually and is based upon the Moody's Corporate Long-Term Bond Yield Index rate (later referred to as Moody's). In 2025, the interest rate was based on the Moody's rate plus one percentage point (6.45%) for amounts credited to accounts in 2013 or later and Moody's plus three percentage points (8.45%) for amounts credited to accounts prior to 2013. NEOs may direct deferrals of STIP awards and performance-adjusted RSU LTIP awards to an annual stock account. The stock accounts are tracked in stock units and accrue additional stock units based upon the payment of dividends. The stock accounts are valued at the fair market value of our common stock. Payments made with respect to any dividend equivalent units that accrue after May 17, 2014, are paid in cash.

Effective for deferral elections made on or after November 1, 2015:

▪Participants may elect to defer RSUs only to the stock account, rather than to a separate RSU account and

▪Participants may no longer elect to receive a distribution after three years (or any later date specified by the participant, in the case of RSUs), as all amounts deferred to the stock account, including deferred RSUs, will be held in that account until separation from service, death, or disability, at which point it will be transferred to a participant's retirement account and paid only in cash based on their distribution elections for the retirement account

NEOs may elect to receive distributions from the cash retirement accounts in any combination of lump sum payment and/or monthly installment payments for up to 25 years. Differing distribution elections may be made for retirement, disability and pre-retirement death. In the event of involuntary separation prior to retirement eligibility, the accounts accrued and vested as of December 31, 2004, may be paid in a single lump sum payment or in three annual installments. In the event of a participant's separation from service for reasons other than retirement, death or disability, accounts accrued on or after January 1, 2005, are paid in a single lump sum payment. Payments may not commence until separation from service. Amounts that were vested as of December 31, 2004, are available for an in-service withdrawal of the full account, subject to a 10% penalty. There is no in-service withdrawal option for retirement accounts accrued on or after January 1, 2005, other than as permitted for hardships under the EDCP.

For deferrals to the stock account prior to November 1, 2015, generally, stock account distributions were made in a lump sum payment in the form of our common stock at the end of the three-year period following the initial deferral, unless further deferred. If further deferred until termination or retirement (or for future deferrals, if termination occurred prior to the end of the initial three-year period, regardless of age at termination), the account was converted to cash, based upon the fair market value of the account at termination, and the balance was rolled over to the corresponding annual retirement account for distribution in lump sum or monthly installments as elected under the retirement account.

## Potential Post-Employment Payments

## 2025 Post-Termination Compensation and Benefits
The following table summarizes the compensation and benefits that would be payable to our NEOs, in the event of a separation of service as of December 31, 2025. For the avoidance of doubt, the below table does not reflect the amendments and restatements of the Executive Severance Plan and the CIC Plan that went into affect on January 1, 2026; nor does the below table contemplate the amended forms of RSU award agreements discussed above.

(1) Benefits provided in these scenarios are provided to all employees on the same terms, if applicable.

(2) Active employee health and wellness benefits are provided, up to a maximum of 18 months under the Executive Severance Plan for the severance period, which is equal to three weeks for every year of service, including 2025 (52 week minimum and 104 week maximum).

The potential post-employment payments discussed in each termination section below disclose the estimated payments and benefits payable to the NEOs upon certain triggering events representing the enhanced or accelerated value of payments and benefits and do not include previously earned and vested amounts payable to such NEOs regardless of the applicable triggering event that have been accrued but not yet paid. The post-termination benefit calculations are based on the following assumptions:

▪The amounts disclosed are estimates of the amounts that would be paid out to the NEOs based on the triggering event. The actual amounts can be determined only at the time of payment.

▪The amounts disclosed do not include benefits provided under the qualified plan, nonqualified supplemental plan and nonqualified cash balance restoration plan as described in the Pension Benefits section and shown in the Pension Benefits table (at the earliest commencement date without reduction) earlier in this proxy statement, unless expressly noted.

▪The amounts disclosed do not include compensation previously earned and deferred into the EDCP. The year-end account balances of the NEOs in the EDCP are set forth in the Nonqualified Deferred Compensation table earlier in this proxy statement. These amounts are payable to the NEO based on the distribution elections made by the NEO at the time the deferral was elected.

▪December 31, 2025, is the last day of employment; accordingly, such amounts reflect the severance and change in control benefits prior to the amendments and restatements of the Executive Severance Plan and CIC Plan that went into effect January 1, 2026.

▪All employees, including the NEOs, are eligible for a full year payout based on actual performance under the STIP if they are employed on December 31, 2025. The 2025 STIP amounts are provided in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table.

▪The LTIP and Other Awards Payments Under Termination table below includes performance-adjusted RSUs, time-based RSUs and restricted stock.

▪The closing common stock price on December 31, 2025, the last trading day of the year ($44.77), is applied to value performance-adjusted RSUs, time-based RSUs and restricted stock.

▪Actual performance is utilized for the 2023 performance-adjusted RSUs. Target payout is assumed for the 2024 and 2025 performance-adjusted RSUs and time-based RSUs.

▪Health care amounts are not disclosed since they are available to all employees under the same circumstances.

**Retirement/Voluntary Termination** 

In the event of a NEO's retirement, the NEO's outstanding equity awards would be prorated and vest based on actual performance as described in the 2025 Post-Termination Compensation and Benefits table above and quantified in the LTIP and Other Award Payments Under Termination table below. Messrs. Tierney, Taylor, Smith, Park and Thomas are not yet retirement eligible as of December 31, 2025, and their outstanding equity awards would be forfeited in the event of a voluntary termination. Retirement eligibility is defined as at least age 55 and five years of service upon an employee's termination date for all LTIP cycles beginning with the 2024-2026 cycle. For the 2023-2025 LTIP cycle, retirement eligibility is defined as at least age 55 and ten years of service upon an employee's termination date.

The present value of the qualified plan, nonqualified supplemental plan, and the Cash Balance Restoration Plan benefits as shown in the Pension Benefits table reflects commencement of retirement benefits at the NEOs' earliest age necessary to receive pension benefits without reduction. Mr. Taylor is entitled to accrued and vested qualified plan and nonqualified supplemental plan benefits as shown in the Pension Benefits table, which cannot be commenced until he meets the age requirement. Mr. Park is a vested cash-balance participant and will have the option to defer or immediately commence his pension benefit upon separation from service. Messrs. Tierney, Smith and Thomas were not yet vested in the qualified plan and Cash Balance Restoration Plan as of December 31, 2025.

**Involuntary Separation** 

In the event of a December 31, 2025 involuntary separation, under the Executive Severance Plan (prior to the amendment and restatement that went into effect January 1, 2026), lump sum severance pay would be provided as follows: Mr. Tierney – $1,500,000 (assuming the independent members of the Board approves the same level of benefits as the other NEOs would receive); Mr. Taylor – $875,000; Mr. Smith – $760,000; Mr. Park – $766,500; and Mr. Thomas – $630,000. Each of the NEOs would also be provided prorated vesting for certain outstanding equity as described in the 2025 Post-Termination Compensation and Benefits table and quantified in the LTIP and Other Awards Payments Under Termination table.

On February 9, 2023, upon the recommendation of the Compensation Committee of the Board, the Board approved a new policy effective immediately that cash severance payable under the Company's Executive Severance Plan or pursuant to any individual contract with an executive officer will not exceed 2.99 times the sum of the executive officer's base salary plus target annual incentive opportunity under the Short-Term Incentive Program, unless the Company seeks shareholder approval.

**Termination Following a CIC** 

In the event of a December 31, 2025 Qualifying Separation, under the CIC Plan (prior to the amendment and restatement that went into effect January 1, 2026), compensation in an amount equal to two times the sum of the amount of annual base salary plus the target annual STIP amount as applicable, in the year during which the date of termination occurs, whether or not fully paid, will be provided as follows: Mr. Tierney – $7,162,500; Mr. Taylor – $3,206,875; Mr. Smith – $2,644,800; Mr. Park – $2,596,519; and Mr. Thomas – $2,075,850. Any NEO having an outstanding restricted stock award would be issued 100% of shares and all dividends accrued upon a CIC. The value of the restricted stock award as well as any performance-adjusted RSUs and time-based RSUs are quantified in the "LTIP and Other Award Payments Under Termination" table below. Excise tax and gross-up provisions are not provided under the CIC Plan. NEOs would be entitled to participate in the group health insurance plan for two years following the participant's termination date. Finally, outplacement services are also offered to NEOs, for a one–year period, capped at $30,000.

**Death & Disability** 

In the event of a NEO's death or Disability (as defined in the applicable plan documents) as of December 31, 2025, each of the NEOs would also be provided additional accelerated vesting for certain outstanding equity as described in the 2025 Post-Termination Compensation and Benefits table above and quantified in the LTIP and Other Award Payments Under Termination table below.

**LTIP and Other Award Payments Under Termination**

In the event of a NEO's separation of service as of December 31, 2025, the NEOs would be provided vested outstanding equity or cash awards as quantified in the LTIP and Other Award Payments Under Termination table below. Awards of performance-adjusted RSUs and time-based RSUs require a termination without cause following a CIC for accelerated vesting. For purposes of the calculations in the table below, we have assumed the equity awards would be replaced by the successor prior to a termination without cause.

(1) Messrs. Taylor and Park do not meet the retirement eligibility requirements as of December 31, 2025 under the 2023-2025 LTIP cycle. Mr. Taylor was not retirement eligible as of December 31, 2025, since he was only 52 years old and Mr. Park was not retirement eligible since he does not have 10 years of service. None of the NEOs met the retirement eligibility requirements as of December 31, 2025 under the 2024-2026 LTIP cycles. Messrs. Tierney, Smith and Park were not retirement eligible since they did not have 5 years of service. Messrs. Taylor and Thomas were not eligible to retire as of December 31, 2025, since they were only 52 years old and 54 years old, respectively. Mr. Thomas also did not have 10 years of service.

(2) The amounts set forth in the "Involuntary Separation" column represent the estimated amounts that would be payable to the NEO as a result of a December 31, 2025 involuntary severance without cause. LTIP awards are prorated based on full months of service. At the time of payment, the LTIP awards will be adjusted for actual performance. If we applied the actual performance results of 81% of target for the 2023-2025 cycle, the values would be as follows: Mr. Tierney – $23,692,879; Mr. Taylor – $7,546,738; Mr. Smith – $4,567,997; Mr. Park – $3,506,392; and Mr. Thomas – $2,476,781. The restricted stock awards for Messrs. Tierney, Taylor and Smith are prorated and paid at target for an involuntary separation.

(3) The amounts set forth in the "Death" column represent the estimated amounts that would be payable to the NEO as a result of a death on December 31, 2025. In the event of a death, the LTIP awards are prorated and payable at target based on the fair market value on the date of death. All restricted stock awards fully vest. LTIP amounts represented in the table are prorated based on full months of service at target.

(4) The amounts set forth in the "Disability" column represent the estimated amounts that would be payable to the NEO as a result of termination due to Disability on December 31, 2025. LTIP awards are prorated and payable at the end of the performance period and based on actual performance. If we applied the actual performance results of 81% of target for the 2023-2025 cycle, the values would be as follows: Mr. Tierney – $24,518,194; Mr. Taylor – $7,958,544; Mr. Smith – $5,073,471; Mr. Park – $3,506,392; and Mr. Thomas – $2,476,781. All restricted stock awards fully vest. LTIP amounts represented in the table are prorated based on full months of service at target.

(5) The amounts set forth in the "Termination Without Cause following a CIC" column represent the estimated amounts that would be payable to the NEO as a result of the double trigger vesting of awards effective as of December 31, 2025. Unvested restricted stock would fully vest at target in the event of a termination without cause following a CIC. LTIP awards are prorated at target in the event of a termination without cause following a CIC.

**CEO Pay Ratio** 

We believe our executive compensation program must be consistent and internally equitable to motivate our employees to perform in ways that enhance shareholder value. We are committed to internal pay equity, and our Committee annually reviews the internal pay ratio between our CEO's total compensation and that for other NEOs and all non-executive employees.

For 2025, the Committee elected to use the same median employee that was originally identified in 2024 to calculate our 2025 pay ratio calculation, as there has been no significant changes to our employee population or employee compensation arrangements in the last fiscal year that we believe would have a significant impact on our pay ratio disclosure.

The process that we used to determine our "median employee" in 2024 is summarized below:

For 2024, we identified the median employee by analyzing the compensation of approximately 12,200 full-time, part-time, seasonal and temporary employees who were employed by us on December 31, 2024, and who had Form W-2 reportable earnings for 2024, other than Mr. Tierney, who was serving as President and CEO at that time. As permitted by SEC rules, to determine the median employee, we calculated and ranked the taxable W-2 wages (Box 5) for 2024. Using this methodology, plus the consistently applied compensation measure, we identified our median employee for 2024.

We calculated the median employee's annual total compensation for 2025 using the same calculation method as in the Summary Compensation Table, which resulted in median employee annual compensation of $160,003. As shown on the Summary Compensation Table, in 2025, Mr. Tierney's CEO Compensation was $13,452,559. As a result, we estimate that the ratio of CEO annualized total compensation to median employee annual total compensation for 2025 is approximately 84:1. We note that, due to our permitted use of reasonable estimates and assumptions in preparing this pay ratio disclosure, the disclosure may involve a degree of imprecision, and thus this pay ratio disclosure is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K using the data and assumptions described above. Given the different methodologies that various public companies will use to determine an estimate of their pay ratio, the estimated ratio reported above should not be used as a basis for comparison between companies.

**Pay Versus Performance** 

The following Pay Versus Performance table ("PVP Table") provides SEC-required information about compensation for 2025 for this Proxy Statement's NEOs, as well as our NEOs from our 2024, 2023, 2022 and 2021 Proxy Statements (each of 2021, 2022, 2023, 2024 and 2025, a "Covered Year"). The PVP Table also provides information about the results for certain measures of financial performance during those same Covered Years. In reviewing this information, there are a few important things we believe you should consider:

▪The information in columns (b) and (d) of the PVP Table comes directly from this year's Summary Compensation Table (or prior years' Summary Compensation Tables), without adjustment;

▪As required by the SEC's PVP rules, we describe the information in columns (c) and (e) of the PVP Table as "compensation actually paid" (or "CAP") to the applicable PVP NEOs. However, these CAP amounts may not necessarily reflect the final

compensation that our NEOs actually earned or received for their service in the Covered Years, respectively. As a result, we urge investors to use caution when evaluating CAP amounts; and

▪As required by the SEC's PVP rules, we provide information in the PVP Table below about our cumulative absolute total shareholder return ("TSR") results, cumulative TSR results for a peer group of companies identified in the PVP Table ("EEI TSR"), and our U.S. GAAP net income results (the "External Measures") during the Covered Years. The peer group used for purposes of this PVP Table disclosure is substantially different than the comparator companies against which we evaluate relative TSR performance for our NEOs for purposes of our performance-adjusted RSU awards, as described above in the CD&A. As a result, we did not necessarily design our NEO compensation to move in tandem with improving, declining or steady achievement in these External Measures.

Due to the use and weighting of the Core Earnings performance measure in our STIP for 2025, we have determined that, pursuant to the SEC's PVP rules, Core Earnings should be designated as the "Company-Selected Measure" for the years 2021 through 2025 and to be included in the far right column of the PVP Table below. We believe it is the most important financial measure that demonstrates how we sought to link executive pay to performance for 2025.

(3) For each Covered Year, our absolute total shareholder return was calculated as the yearly percentage change in our cumulative total shareholder return on our common stock, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for a period beginning with our closing price on NYSE on December 31, 2020 ($30.61 per share) through and including the last day of the Covered Year (each one-year, two-year, three-year, four-year and five-year periods, a "Measurement Period"), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period ($44.77 per share for December 31, 2025, $39.78 per share for December 31, 2024, $36.66 per share for December 31, 2023, $41.94 per share for December 31, 2022, and $41.59 per share for December 31, 2021, divided by (b) our closing share price at the beginning of the Measurement Period ($30.61 per share).

these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of the Measurement Period to produce the Covered Year-end values of such investment as of the end of 2025, 2024, 2023, 2022 and 2021, as applicable. Because Covered Years are presented in the table in reverse chronological order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.

(4) For purposes of this pay versus performance disclosure, our peer group is EEI's Index of Investor-Owned Electric Utility Companies (the "Peer Group"). For each Covered Year, our peer group cumulative total shareholder return was calculated based on a deemed fixed investment of $100 through the Measurement Period, assuming dividend reinvestment for the entities in the Peer Group (on a weighted basis depending on the respective entity's stock market capitalization at the beginning of the Measurement Period).

(5) For the years 2021-2024, for illustration purposes, Operating Earnings were converted to Core Earnings because Core Earnings was not the Company selected measure until 2025. The conversion is consistent with how Core Earnings is defined below in the following footnote.

(6) For 2025, Core Earnings is disclosed in millions and is calculated using the aggregate GAAP earnings adjusted to exclude Net Pension/OPEB credits and Signal Peak earnings impact, and other special items that are consistent with the Company's non-GAAP external reporting. Results for 2025 included the following adjustments: in addition to the special items that adjust GAAP earnings to Core Earnings as reported externally, the impacts of unforeseen accounting and legislative or regulatory changes as instituted by authoritative organizations were included as adjustments. Other strategic decisions may also apply if they are presented to and approved by the Board.

**<u>Descriptions of Relationships Between CAP and Certain Financial Performance Measure Results</u>**

The following charts provide, across the Covered Years, a description of the relationships between (1) our cumulative total shareholder return and the cumulative total shareholder return of the Peer Group, (2) the compensation actually paid to the PEOs and the financial performance measures results set forth in columns (f), (h) and (i) of the PVP Table above, and (3) average compensation actually paid to our non-PEO named executive officers and the financial performance measures results set forth in columns (f), (h) and (i) of the PVP Table above.

CAP to our PEO, Mr. Tierney, totaled $17.9 million in 2025 and $10.7 million in 2024, down from $30.9 million in 2023. This decrease corresponds with 2023 being Mr. Tierney's first year as PEO which included a combination of a one-time hiring bonus and performance-based and time-based restricted awards. CAP to our non-PEO NEOs averaged $4.3 million in 2025, up from $2.4 million in 2024. This increase corresponds with an increase in stock price performance in the latest year. The charts below further illustrate the relationships between CAP to our PEOs and non-PEO NEOs and financial performance measures over the past five years.

(1) Brian X. Tierney, Board Chair, President and CEO, is excluded from this table, as he does not receive any incremental compensation for his service as Board Chair. Compensation received by Mr. Tierney for 2025 is shown in the "2025 Summary Compensation Table" above.

(2) The amounts set forth in the Fees Earned or Paid in Cash column consist of fees earned in cash whether paid in cash, deferred into the FirstEnergy Corp. Deferred Compensation Plan for Outside Directors ("DDCP") or elected to be received in stock in lieu of cash.

(3) The amounts set forth in the Stock Awards column represent the equity retainer received under the FirstEnergy Corp. 2020 Incentive Compensation Plan ("2020 Incentive Plan") in the form of shares of common stock. Each amount constitutes the aggregate grant date fair value of stock awards for fiscal 2025 calculated in accordance with "FASB" ASC Topic 718. The equity retainer is typically paid in quarterly installments. The fair value per share on the grant dates for each director listed in the table was: $40.23 on April 1, 2025; $40.26 on July 2, 2025; $45.93 on October 1, 2025; and $45.00 on January 2, 2026. Share amounts are rounded down to the nearest whole share. There were no option awards or stock awards outstanding as of December 31, 2025.

(4) The amounts set forth in the "All Other Compensation" column include compensation not required to be included in any other column. No such compensation occurred in 2025.

(5) Ms. Boyd did not receive compensation for their service on the Board pursuant to arrangements with Blackstone.

**Compensation of Directors** 

We use a combination of cash and equity-based incentive compensation in order to attract and retain qualified candidates to serve on your Board. Equity compensation provides incentives to directors linking their personal interests to our long-term financial success and to increases in shareholder value. In setting director compensation, we take into consideration the significant amount of time that directors spend in fulfilling their duties to us as well as the skill level required of members of your Board. A review is performed every other year to help ensure the competitiveness of non-employee director compensation. Only non-employee directors receive the compensation described below for their service on your Board. Further, pursuant to arrangements with Ms. Boyd (and previously Mr. Klimczak) and Blackstone, Ms. Boyd and Mr. Klimczak do not, and did not, respectively, receive compensation for their service on the Board and are not required to participate in share ownership guidelines.

**Fee Structure** 

For 2025, each non-employee director received an annual cash retainer of $120,000 and an annual equity retainer valued at approximately $170,000 and paid in the form of our common stock. The Chairs of the Compensation; Governance; Finance; and Operations and Safety Oversight Committees each received an additional $20,000 cash retainer in 2025 for serving as a committee chairperson. The Chair of the Audit Committee received an additional $25,000 cash retainer in 2025. Ms. Hicks is entitled to an additional $35,000 cash retainer for her role as Lead Independent Director. Ms. Turner currently directs the Company to pay her cash retainers to her wholly owned limited liability company, and therefore, her cash retainers are not eligible for deferral as described below. The total annual compensation of each non-employee director shall not exceed the value of $750,000 in the aggregate of all cash compensation and the value of the applicable equity retainer.

Equity and cash retainers and chairperson retainers were paid in quarterly installments. Any equity compensation and any compensation deferred into equity was granted under the 2020 Incentive Plan. Directors are responsible for paying all taxes associated with cash and equity retainers. We do not gross up equity grants to directors to cover tax obligations.

**Share Ownership Guidelines** 

We believe it is critical that the interests of directors and shareholders be clearly aligned. As such, similar to the NEOs identified in the CD&A, directors are also subject to share ownership guidelines. Within 90 days of their election to your Board, a director must beneficially own a minimum of 100 shares of our common stock. Within five years of joining your Board, each director is required to own shares of our common stock with an aggregate value of at least six times the annual cash retainer (currently $720,000 in common stock). Each director has either attained the required share ownership guideline or is expected to attain the required share ownership guideline within the allotted amount of time. The share ownership guidelines are reviewed by the Compensation Committee on an annual basis and were last reviewed at the Compensation Committee's July 2025 meeting.

For 2025, the following directly and indirectly held shares were included in determining whether a non-employee director met his/her ownership guidelines:

▪Shares directly or jointly owned in certificate form or in a stock investment plan;

▪Shares held individually or jointly by a broker, or, in certain circumstances, held in trust, or in an individual retirement account ("IRA"), shares held by a spouse, or other beneficially owned shares, to the extent known by the Company; and

▪All units held in the DDCP, discussed below, which units are payable in shares.

**Deferred Compensation Plan for Outside Directors** 

The DDCP is a nonqualified deferred compensation plan that provides directors the opportunity to defer compensation. Directors may defer up to 100 percent of their cash retainer into cash or stock accounts. Deferrals into the cash account can be invested in one of nine funds, similar to the investment funds available to all of our employees through the FirstEnergy Corp. Savings Plan, or in a Company-paid annually adjusted fixed income account. The Company paid interest at an annual rate of 6.45% on funds deferred into cash accounts beginning in 2013 and 8.45% on funds deferred into cash accounts prior to 2013. The interest rate received by the directors is the same rate received by all participants under the EDCP, as discussed further in the CD&A above.

For stock accounts, dividend equivalent units are accrued quarterly and applied to the directors' accounts on each dividend payment date using the closing price of our common stock on that date. Payments made with respect to any dividend equivalent units that accrue will be paid in cash.

**Other Payments or Benefits Received by Directors** 

The corporate aircraft is available, when appropriate, for transportation to and from Board and committee meetings and training seminars. The Company pays all fees associated with director and officer insurance and business travel insurance for our directors. In 2025, our directors were eligible to receive perquisites including limited personal use of corporate aircraft and matching charitable contributions, the collective value of which was less than $10,000 for each director. Directors are responsible for paying all taxes associated with perquisites and personal benefits.

All directors have entered into written indemnification agreements, which are intended to secure the protection for our directors contemplated by our Code of Regulations and Ohio law. Each indemnification agreement provides, among other things, that we will, subject to the agreement terms, indemnify a director if by reason of their corporate status as a director, the person incurs losses, liabilities, judgments, fines, penalties, or amounts paid in settlement in connection with any threatened, pending, or completed proceeding, whether of a civil, criminal, administrative, or investigative nature. In addition, each indemnification agreement provides for the advancement of expenses incurred by a director, subject to certain exceptions, in connection with proceedings covered by the indemnification agreement. As a director and officer, the agreement for Mr. Tierney addresses indemnity in both roles.

# Security Ownershi p of Management
The following table shows shares of common stock beneficially owned (as beneficial ownership is defined in Rule 13d-3 under the Exchange Act) as of March 16, 2026, by each director, director nominee, the NEOs and all directors, director nominees and executive officers as a group. According to the rules adopted by the SEC, a person "beneficially owns" securities if the person has or shares the power to vote them or to direct their investment or has the right to acquire beneficial ownership of such securities within 60 days through the exercise of an option, warrant, right of conversion of a security or otherwise.

(1) The amounts set forth in this column include any shares with respect to which the executive officer, NEO or director may directly or indirectly have sole or shared voting or investment power. Unless otherwise noted below, each individual or member of the group has sole voting and investment power with respect to the shares beneficially owned.

(2) Deferred shares and other amounts payable in stock under the DDCP are held as stock units and are not beneficially owned (as defined in Rule 13d-3 under the Exchange Act) and are therefore not included in the table above. However, such stock units are counted for purposes of non-employee director share ownership guidelines. The stock unit holdings of the directors under the DDCP are as follows.

# Certain Relationships and R elated Person Transactions
Based on our size and varied business operations, we may engage in transactions with companies and other organizations in which a member of your Board, executive officer, or such person's immediate family member also may be a board member, executive officer, or significant investor. In some of these cases, such person may have a direct or indirect material interest in the transaction with the Company. We recognize that related person transactions have the potential to create perceived or actual conflicts of interest and could create the appearance that decisions are based on considerations other than the best interests of the Company and its shareholders. Accordingly, as a general matter, it is our preference to avoid related person transactions. However, there are situations where related person transactions may be in, or may not be inconsistent with, the best interests of the Company and its shareholders. Your Board has determined that it is appropriate and necessary to have a process in place to identify and provide proper review of any related person transactions.

Based on the foregoing, your Board established a written Related Person Transactions Policy (the "Policy") that has been implemented by the Governance Committee in order to effectuate the review, approval and ratification process surrounding related person transactions. This Policy supplements the Company's other conflict-of-interest policies set forth in the FirstEnergy Conflicts-of-Interest Policy and Code of Business Conduct. Related person transactions may be entered into or continued only if a majority of the disinterested members of the Governance Committee or your Board approves or ratifies the transaction in accordance with the Policy. The Chair of the Governance Committee also has the delegated authority between meetings to review and determine whether a transaction should be approved or ratified in accordance with the Policy. In making its decisions, the Governance Committee, Chair of the Governance Committee or your Board will review current and proposed transactions by taking into consideration the Policy, which includes the definitions and terms set forth in Item 404 of Regulation S-K.

As part of the Policy, our management established review procedures for any transaction, proposed transaction or any known material amendment to a transaction, in which we are currently, or in which we may be, a participant in which the amount exceeds $120,000, and in which the related person, as defined in Item 404 of Regulation S-K, had or will have a direct or indirect material interest. In early 2026 our directors, current executive officers and certain former directors completed a questionnaire to assist your Company in identifying and assessing any potential related person transactions. Your Company facilitates the review by examining its financial records based on responses to the questionnaires. Any known related entities of the related persons are identified as such in the applicable computer system so that necessary business units are made aware of a potential related person transaction or proposed transaction involving the Company and a related entity. As applicable, management brings transactions to the attention of the Governance Committee, Chair of the Governance Committee or your Board for its review, approval or ratification.

When reviewing a transaction, the Governance Committee, led by its Chair, or your Board reviews the material facts of the related person's relationship to the Company, and his or her interest in the transaction, as well as the aggregate value of such transaction to the Company. Since January 1, 2025, we participated in the transactions described below, in which the amount involved exceeded $120,000 and in which any Board member, Board member nominee, executive officer, beneficial owner of more than five percent of our common stock, or a member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest. Pursuant to the terms of the Policy, your Board's Governance Committee and/or the Chair of the Governance Committee ratified and approved the transactions described below.

During 2025, State Street Corporation ("State Street"), a beneficial owner of at least 5% of the Company's common stock, provided asset management, custodial services and trustee services relating to a trust associated with a Company employee benefit plan. State Street's fees were approximately $190,500 from January 1, 2025, through March 16, 2026, for such services. Their fees are unrelated to their common stock ownership, resulted from arm's-length negotiations, and are reasonable in amount and reflect market terms and conditions.

***Related Person Transactions involving the Blackstone Group L.P.*** 

On November 6, 2021, the Company entered into Common Stock Purchase Agreement (the "Blackstone PSA") with BIP Securities II-B L.P., an affiliate of Blackstone Infrastructure Partners L.P. ("Blackstone"), for the private placement of 25,588,535 shares of the Company's common stock at a price of $39.08 per share (the "Private Placement"). Pursuant to the Blackstone PSA, and for so long as Blackstone beneficially owns at least 75% of the shares of common stock acquired by it at the closing of the Private Placement (such period, the "Nomination Period"), Blackstone will have the right to nominate one person for election to the Board (the "Blackstone Nominee") and the Company will: (i) upon the occurrence of a vacancy on the Board during the Nomination Period, if the Blackstone Nominee is not then serving as a member of the Board, cause the Blackstone Nominee to be appointed to the Board; and (ii) in connection with each annual meeting of the stockholders of the Company at which directors are generally elected during the Nomination Period, (A) include the Blackstone Nominee as a nominee for election to the Board; (B) include the Blackstone Nominee in the Company's notice of annual meeting (or any supplement thereto); (C) not nominate more nominees than the number of persons to be elected to the Board at such meeting (which amount shall include the Blackstone Nominee); and (D) use reasonable best efforts to cause the election of the Blackstone Nominee so nominated by the Company (including by (x) recommending that the Company's stockholders vote in favor of the election of the Investor Nominee and (y) otherwise support the Investor Nominee for election in a manner no less rigorous and favorable than the manner in which the Company supports its other nominees in the aggregate). Pursuant to the Blackstone PSA and Blackstone's recommendation, the Board agreed to nominate Ms. Boyd for election as a director of the Company at the 2026 Annual Meeting.

The Company also entered into a Director and Officer Indemnification Agreement with Ms. Boyd.

In the event that Blackstone ceases to beneficially own at least 75% of the shares of Common Stock acquired by it at the closing of the Private Placement, if requested by the Board, Blackstone shall cause Ms. Boyd or its then nominee to immediately resign from the Board.

# Audit Commit tee Report
The Audit Committee of your Board is charged with assisting your full Board in fulfilling its oversight responsibility with respect to the quality and integrity of the accounting, auditing and financial reporting practices of the Company. The Audit Committee acts under a written charter that is reviewed annually, revised as necessary, and is approved by your Board. The charter specifies that the Audit Committee is directly responsible for the appointment, compensation and retention of, and the oversight of the work and pre-approval of all services provided by the Company's independent registered public accounting firm, which was PricewaterhouseCoopers LLP during 2025. In connection with the Audit Committee's approval of any non-audit services, the Audit Committee considers whether the independent registered public accounting firm's performance of any non-audit services is compatible with the independent auditor's independence.

As part of the Audit Committee's annual auditor engagement process, the Audit Committee considers whether to rotate the independent registered public accounting firm. The Audit Committee also participates in the selection of and ensures the regular rotation of the lead audit partner and concurring partner of the Company's independent registered public accounting firm every five years. PricewaterhouseCoopers LLP has been the Company's independent auditor since 2002. The Audit Committee currently believes that there are benefits to having an independent auditor with an extensive history with the Company. In connection with its auditor engagement process, the Audit Committee considers the continued independence of PricewaterhouseCoopers LLP and considers the benefits including: quality audit work and accounting advice due to PricewaterhouseCoopers LLP's institutional knowledge of our business and operations, accounting policies and financial systems, and internal control framework; knowledge of the utility industry; and operational efficiencies and a resulting lower fee structure because of PricewaterhouseCoopers LLP's history and familiarity with our business. Using a framework developed by management, the Audit Committee also assesses the appropriateness and reasonableness of PricewaterhouseCoopers LLP's fees relative to the Company's business needs and as compared to fees incurred by peer companies of comparable financial statement risk, size and complexity of business and related internal control environment.

In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with management the audited financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. In performing its review, the Audit Committee discussed the propriety of the application of accounting principles by the Company, the reasonableness of significant judgments and estimates used in the preparation of the financial statements, and the clarity of disclosures in the financial statements.

The Audit Committee reviewed and discussed with the Company's independent registered public accounting firm, PricewaterhouseCoopers LLP, their opinion on the conformity of the audited financial statements with accounting principles generally accepted in the United States. This discussion covered the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC.

The Audit Committee received the written disclosures and the letter from the independent registered public accounting firm regarding their independence from the Company as required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the Audit Committee concerning independence and discussed with the independent registered public accounting firm such firm's independence.

The Audit Committee discussed with the Company's internal auditors and independent registered public accounting firm the overall scope, plans and results of their respective audits. The Audit Committee met with the internal auditors and independent registered public accounting firm, with and without management present, to discuss the results of their examinations, their evaluations of the Company's internal controls, and the overall quality of the Company's financial reporting process.

Based on the above reviews and discussions, the Audit Committee recommended to your Board that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC.

Audit Committee Members: Leslie M. Turner (chair), Heidi L. Boyd, Jana T. Croom and James F. O'Neil III.

The Audit Committee, in accordance with its charter and in compliance with all applicable legal and regulatory requirements promulgated from time to time by the NYSE and SEC, has a policy under which the independent registered public accounting firm cannot be engaged to perform non-audit services that are prohibited by these requirements. The charter further states that any engagement of the independent registered public accounting firm to perform other audit-related or any non-audit services must have approval in advance by the Chair of the Audit Committee upon the recommendation of the Vice President, Controller and Chief Accounting Officer. Such approved engagement is then presented to the Audit Committee at its next regularly scheduled meeting. All audit and non-audit services provided by PricewaterhouseCoopers LLP in 2025 and 2024 were pre-approved.

# Trans parency in Corporate Contributions
***2025 Political and Lobbying Action Plan Audit***

The Governance Committee engaged Nielsen Merksamer LLP to conduct an audit of FirstEnergy's 2025 Political and Lobbying Action Plan (the "Plan"). As part of its audit, Nielsen Merksamer LLP interviewed FirstEnergy employees, board members, and external consultants; reviewed internal documents including the 2025 Political and Lobbying Action Plan approved by the Board of Directors, quarterly updates to the Plan, the First Energy Code of Conduct, internal training materials and other relevant Company policies and procedures. Nielson Merksamer considered applicable laws, regulations and best practices and examined political reports and processes related to the FirstEnergy Political Action Committee and lobbying by FirstEnergy employees who are registered lobbyists and external consultants engaged to lobby on behalf of FirstEnergy.

Nielsen Merksamer did not identify any material deviations from the Plan. Based on the review, Nielsen Merksamer provided the Board of Directors a report with recommendations and observations regarding policy alignment, plan implementation, program effectiveness and suggested areas of improvement, including methods for tracking disclosable lobbying time, and preparing for expanded political engagement with additional resources and approaches to training. The Company will address all recommendations and report its progress to the Governance Committee.

Pursuant to FirstEnergy's obligations in Section 5(D) ("Transparency in Corporate Contributions") of the Deferred Prosecution Agreement filed on July 22, 2021, in *United States v. FirstEnergy Corp.*, Case No. 1:21cr00086 (SDOH), below are lists of payments made by FirstEnergy to entities incorporated under 26 U.S.C. § 501(c)(4), and to entities known by FirstEnergy to be operating for the benefit of a public official, either directly or indirectly, for time periods beginning January 1, 2025 through December 31, 2025. Upon the recommendation of the Governance Committee, the Board approves the Political and Lobbying Action Plan in December prior to each year.

# Questions and Answers ab out the Annual Meeting

## Proxy Ma terials

---

| | | |
|:---|:---|:---|
| **1**  | **Q:**  | **Why did I receive these proxy materials?** |
|  | **A:** | You received these proxy materials because you were a shareholder of record or beneficial owner (as defined below) of shares of common stock of FirstEnergy Corp. as of the close of business on March 23, 2026, the record date (the "Record Date"). The Annual Meeting will be held on Wednesday, May 20, 2026. We began distributing these proxy materials to shareholders on or about April 1, 2026. |
| **2**  | **Q:**  | **What is the difference between holding shares as a "shareholder of record" and holding shares in "street name" or as a "beneficial owner"?** |
|  | **A:** | ***Shareholder of Record:*** If your shares are registered directly in your name with our transfer agent, Equiniti Trust Co LLC ("Equiniti"), you are a shareholder of record of the shares. As the shareholder of record, you have the right to vote your shares directly or to grant a proxy to vote your shares to a representative of the Company or to another person, and you may attend the Annual Meeting (please see the "Attending the Virtual Annual Meeting" section of the "Questions and Answers about the Annual Meeting" below for instructions on how to register in advance). As a record holder you have received either a proxy card to use in voting your shares or a Notice of Internet Availability which instructs you how to vote. |
|  |  | ***Beneficial Owner:*** If your shares are held for you in a brokerage, bank or other institutional account, it is likely that you are the beneficial owner of shares, meaning that you hold shares in "street name." You are also a beneficial owner if you own shares through the FirstEnergy Corp. Savings Plan (the "Savings Plan"). |
|  |  | As a beneficial owner of shares, you have the right to direct the registered holder to vote your shares, and you may attend the Annual Meeting (please see the "Attending the Virtual Annual Meeting" section of the "Questions and Answers about the Annual Meeting" below for instructions on how to register in advance). Your bank, broker or other institution has provided a voting instruction form for you to use in directing how your shares are to be voted. However, since a beneficial owner is not the shareholder of record, you may not vote your shares virtually at the Annual Meeting unless you obtain a legal proxy from the registered holder of the shares giving you the right to do so. Additionally, if you are a Savings Plan participant, because the Savings Plan's Trustee is the only one who can vote your Savings Plan shares, you cannot vote your Savings Plan shares virtually at the Annual Meeting (although you may attend the Annual Meeting by following the instructions on how to register in advance in the "Attending the Virtual Annual Meeting" section of the "Questions and Answers about the Annual Meeting" below). |
| **3**  | **Q:**  | **Can I view future FirstEnergy proxy materials and annual reports on the internet instead of receiving paper copies?** |
|  | **A:** | Yes. If you received paper copies of this proxy statement and the annual report and you are a shareholder of record, you can elect to view future proxy statements and annual reports on the internet by marking the designated box on your proxy card or by following the instructions when voting by internet or by telephone. If you choose this option, prior to the next annual meeting, you will be mailed a paper copy of the proxy card along with instructions on how to access the proxy statement and annual report using the internet unless applicable regulations require delivery of printed proxy materials. Your choice will remain in effect until you notify us that you wish to resume mail delivery of these documents. |
|  |  | If you previously elected to access your proxy materials over the internet, you will not receive the Notice of Internet Availability of Proxy Materials ("Notice of Internet Availability") or paper copies of proxy materials in the mail unless  |

required by law. Instead, you will receive a paper copy of the proxy card along with instructions on how to access the proxy statement and annual report using the internet.<br>

---

| | | |
|:---|:---|:---|
|  |  | If you received a Notice of Internet Availability, you may not receive printed copies of proxy statements and annual reports in the future unless required by law. However, you may elect to be mailed a paper proxy card with instructions on how to access proxy statements and annual reports using the Internet for future meetings by following the instructions when voting. The Notice of Internet Availability also contains instructions on how you may request delivery of proxy materials in printed form for the Annual Meeting or on an ongoing basis, if desired. |
|  |  | If you are a beneficial owner, refer to the information provided by your broker, bank or other nominee for instructions on how to elect to view future FirstEnergy proxy statements and annual reports on the Internet instead of receiving paper copies. |
| **4**  | **Q:**  | **Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of receiving a full set of printed proxy materials?** |
|  | **A:** | To reduce the environmental impact and related costs of the Annual Meeting, we are pleased to again furnish the proxy materials over the internet. As a result, we are sending a number of our shareholders a Notice of Internet Availability instead of a printed copy of the proxy materials. All shareholders receiving the Notice of Internet Availability will have the ability to access the proxy materials and vote via the internet and to request a printed copy of the proxy materials by mail, if desired. Instructions on how to access the proxy materials over the internet, to vote online, and to request a printed copy may be found in the Notice of Internet Availability. The Notice of Internet Availability identifies the items to be voted on at the Annual Meeting, but shares cannot be voted by marking, writing on and/or returning the Notice of Internet Availability. Any Notice of Internet Availability that is returned will not be counted as votes. In addition, the Notice of Internet Availability contains instructions on how you may request delivery of proxy materials in printed form for this Meeting or on an ongoing basis, if desired. |
| **5**  | **Q:**  | **Why did we receive just one copy of the Proxy Statement and annual report when we have more than one stock account in our household?** |
|  | **A:** | Where possible, we follow the SEC rule that permits us to send one copy each of this Proxy Statement and the annual report to a household if shareholders provide written or implied consent. We previously mailed a notice to eligible registered shareholders stating our intent to use this rule unless a shareholder provided an objection. Using this rule reduces unnecessary publication and mailing costs. Shareholders continue to receive a separate proxy card or opportunity to vote via the internet, as applicable, for each stock account. If you are a registered shareholder and received only one copy each of the Proxy Statement and the annual report in your household, you can request additional copies for some or all accounts for this year or in the future, either by calling Shareholder Services at 1-800-736-3402 or by writing to FirstEnergy Corp., c/o Equiniti Trust Co LLC, P.O. Box 2016, New York, NY 10272-2016, and we will promptly deliver the requested copies. You also may contact us in the same manner if you are receiving multiple copies of this Proxy Statement and/or the annual report in your household and desire to receive one copy. If you are not a registered shareholder and your shares are held by a bank, broker, or other institution you will need to contact such bank, broker, or other institution to revoke your election and receive multiple copies of these documents, or to request to receive one copy for your household.<br>|
| **6**  | **Q:**  | **Who is soliciting my vote, how are proxy cards being solicited, and what is the cost?** |
|  | **A:** | Your Board is soliciting your vote. We have arranged for the services of Sodali & Co to solicit votes personally or by telephone, mail, or other electronic means for a fee not expected to exceed $21,000, plus reimbursement of reasonable expenses. Votes also may be solicited in a similar manner by officers and employees of the Company and members of your Board on an uncompensated basis. The Company will pay all reasonable solicitation costs and will reimburse banks, brokers or other nominees for postage and expenses incurred by them for sending proxy materials to beneficial owners. |

|:---|:---|:---|
| **8**  | **Q:**  | **What is a quorum and what other voting information should I be aware of?** |
|  | <br>**A:** | <br>As of the Record Date, 578,398,650 shares of our common stock were outstanding. A majority of these shares represented at the Annual Meeting either virtually or by proxy constitutes a quorum. A quorum is required to conduct business at the Annual Meeting. All shares represented at the Annual Meeting are counted for the purpose of determining a quorum. You are entitled to one vote for each share of common stock you owned on the Record Date.<br>If a beneficial owner of shares does not provide the bank or broker holding such shares with specific voting instructions, under the rules of the NYSE, the shareholder's bank or broker may generally vote on "routine" matters, but cannot vote on "non-routine" matters. "Broker non-votes" occur when a beneficial owner of shares held in street name fails to provide instructions to the broker, bank, or other holder of record as to how to vote on matters deemed non-routine.<br>If you are a beneficial owner, we encourage you to provide instructions to your bank, broker, or other institution by executing the voting form supplied to you by that entity. Pursuant to applicable rules, if your shares are held in a broker account, you must provide your broker with voting instructions for all matters to be voted on at the Annual Meeting except on Item 2. A broker will be permitted to vote your shares on Item 2 without your instructions because Item 2 is considered a "routine" matter under applicable NYSE rules; however, your broker cannot vote your shares on any other items unless you provide instructions because such other items are deemed to be "non-routine" matters under NYSE rules. Therefore, your failure to give voting instructions means that your shares will not be voted on any "non-routine" items and, as applicable, your unvoted shares will be broker non-votes.<br>An item to be voted on may require a percentage of votes cast, rather than a percentage of shares outstanding, to determine passage or failure. Votes cast is defined to include both "For" and "Against" votes and excludes abstentions and broker non-votes.<br>If you properly sign and return your proxy card but your proxy card is not completed properly, such as by having marked more than one box for an item, your vote for that particular item will be treated as an abstention. |

| **11**  | **Q:** | **Where can I find the voting results of the Annual Meeting?** |

***If you are a participant in the FirstEnergy Corp. Savings Plan,*** your proxy card will include the shares of common stock held for your account in the FirstEnergy Corp. Savings Plan and any other shares registered with our transfer agent, Equiniti, as of the Record Date. Subject to the Employee Retirement Income Security Act of 1974, as amended, and pursuant to the Savings Plan provisions, the Savings Plan's Trustee will vote all shares as directed by Savings Plan participants and shares for which the Savings Plan's Trustee does not receive timely voting directions will be voted in the same proportion as the shares held under the Savings Plan for which the Savings Plan's Trustee receives timely voting directions. Because the Savings Plan Trustee is the only one who can vote your FirstEnergy Corp. Savings Plan shares, you may not vote such shares at the Annual Meeting.

***Beneficial owners*** (other than participants in the FirstEnergy Corp. Savings Plan) will receive instructions from the holder of record (the bank, broker, institution or other nominee that holds your shares) that you must follow for your shares to be voted. Also, please note that if you wish to vote virtually at the Annual Meeting, you must request a legal proxy from your bank, broker, or other nominee that holds your shares and present that legal proxy identifying you as the beneficial owner of your shares of FirstEnergy common stock and authorizing you to vote those shares at the Annual Meeting.

---

| | | |
|:---|:---|:---|
| **14**  | **Q:** | **How may I revoke my proxy?** |
|  | **A:** | You may revoke your appointment of a proxy or change your related voting instructions one or more times by timely:<br>&nbsp;&nbsp;&nbsp;&nbsp;▪Mailing a proxy card that revises your previous appointment and voting instructions;<br>&nbsp;&nbsp;&nbsp;&nbsp;▪Voting by Internet or telephone after the date of your previous appointment and voting instructions;<br>&nbsp;&nbsp;&nbsp;&nbsp;▪Voting virtually at the Annual Meeting (other than participants in the FirstEnergy Corp. Savings Plan); or<br>&nbsp;&nbsp;&nbsp;&nbsp;▪Notifying the Corporate Secretary of the Company in writing prior to the commencement of the Annual Meeting (other than participants in the FirstEnergy Corp. Savings Plan). |
|  |  | The proxy tabulator will treat the last instructions it receives from you as final. For example, if a proxy card is received by the proxy tabulator after the date that a telephone or internet appointment is made, the tabulator will treat the proxy card as your final instruction. For that reason, it is important to allow sufficient time for your voting instructions on a mailed proxy card to reach the proxy tabulator before changing them by telephone or internet. Please note that unless you are voting virtually at the Annual Meeting, in order to be counted, the revocation or change must be received by the applicable dates and times, discussed above in Question 13, which also includes instructions on how to vote. |
|  |  | If you are a beneficial owner of shares, you must follow the directions you receive from your bank, broker, or other institution to change your vote. |

<u>Advance Notice Procedures:</u><br>The Code of Regulations provide that we must receive the notice of intention to introduce an item of business, including nominations of director candidates for election to your Board, at an annual meeting not less than 30 nor more than 60 calendar days prior to the annual meeting. In the event public announcement of the date of the annual meeting is not made at least 70 calendar days prior to the date of the meeting, notice must be received not later than the close of business on the 10th calendar day following the day on which the public announcement is first made. Accordingly, if a public announcement of the date of the 2027 annual meeting of shareholders is made at least 70 calendar days prior to the date of the meeting and assuming that our 2027 annual meeting of shareholders is held on the third Wednesday in May 2027, we must receive any notice of intention to introduce an item of business at that meeting no earlier than March 20, 2027 and no later than April 19, 2027; otherwise, we must receive any notice of intention to introduce an item of business at that meeting no later than the close of business on the 10th calendar day following the day on which the public announcement is first made. If we do not receive notice as set forth above or if certain other requirements of applicable law are met, the persons named as proxies in the proxy materials relating to that meeting will use their discretion in voting the proxies when these matters are raised at the meeting.<br><u>Proxy Access Procedures:</u><br>In addition, we have adopted a proxy access right to permit, under certain circumstances, a shareholder or a group of shareholders to include in our annual meeting proxy statement director candidates whom they have nominated. These proxy access provisions in our Code of Regulations provide, among other things, that a shareholder or group of up to 20 shareholders seeking to include director candidates in our annual meeting proxy statement must own, in the aggregate, 3% or more of the Company's issued and outstanding Common Stock continuously for at least three years. The number of shareholder-nominated candidates appearing in any annual meeting proxy statement cannot exceed 20% of the number of directors in office as of the last day on which the applicable notice may be delivered or received or, if such amount is not a whole number, the closest whole number below 20%, and in any event, not less than two shareholder-nominated candidates. Such nomination must conform to the applicable requirements in our Code of Regulations and must be received by our Corporate Secretary at the principal offices of the Company no earlier than 150 calendar days and no later than 120 calendar days prior to the first anniversary of the date that the Company released its proxy for the previous year's annual meeting. Accordingly, for the 2027 annual meeting of shareholders, such notice must be received at our principal officers no earlier than November 2, 2026, and no later than December 2, 2026, assuming the 2027 annual meeting of shareholders is not advanced more than 30 calendar days and not delayed by more than 60 calendar days of the date of the anniversary of the 2026 annual meeting of shareholders.<br>Please refer to our Code of Regulations for the complete requirements and procedures. Which is available on the SEC website and upon written request to the Corporate Secretary, FirstEnergy Corp., 341 White Pond Dr., Akron, Ohio 44320.<br>***SEC Rule 14a-19 Universal Proxy Procedures*** <br>In addition to satisfying the requirements under our Code of Regulations, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees for election at the 2027 annual meeting of shareholders other than the Company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act. Such notice must be postmarked or transmitted electronically to the Corporate Secretary, FirstEnergy Corp., 341 White Pond Dr., Akron, Ohio 44320, no later than 60 calendar days prior to the anniversary date of the 2026 annual meeting of shareholders, assuming the 2027 annual meeting of shareholders is not changed by more than 30 calendar days of the date of the anniversary of the 2026 annual meeting of shareholders.<br>
