PROXY STATEMENT SUMMARY

The summary below highlights information contained elsewhere in this proxy statement. It does not contain all the information that you should consider in connection with the matters before the Annual Meeting. Please read the entire proxy statement carefully before voting your shares.

ABOUT GULFPORT

Gulfport is an independent natural gas-weighted exploration and production company with assets primarily located in the Appalachia and Anadarko basins. Our principal properties are located in eastern Ohio targeting the Utica and Marcellus and in central Oklahoma targeting the SCOOP Woodford and Springer formations. Our corporate headquarters is located in Oklahoma City, Oklahoma and shares of Gulfport’s Common Stock trade on the New York Stock Exchange (NYSE) under the ticker symbol “GPOR”.

BUSINESS STRATEGY

Gulfport aims to create sustainable value through the economic development of our significant resource plays in the Utica and SCOOP operating areas. Our strategy is to develop our assets in a manner that generates sustainable cash flow, expands margins and enhances operating efficiencies, all while improving our environmental and safety performance. To accomplish these goals, we allocate capital to projects we believe offer the highest rate of return and deploy leading drilling and completion techniques and technologies in our development efforts. We believe our plan to generate adjusted free cash flow on an annual basis will allow us to return capital to shareholders and increase our resource depth through acquiring incremental leasehold opportunities that provide optionality for our future development plans.

Core Assets | Employees | 2024 Production | 2024 Production Mix
Utica/Marcellus and SCOOP | 235 people as of Dec. 31, 2024 | 1,054 MMcfe per day | 92% natural gas, 6% natural gas liquids and 2% oil

DIRECTORS

Our Board is comprised of seven directors, including the Company’s Chief Executive Officer, John Reinhart, and six non-employee directors, Timothy Cutt, David Wolf, Jason Martinez, Jeannie Powers, David Reganato, and Mary Shafer-Malicki. They are diverse, industry-leading experts with an average of approximately 25 years of industry leadership experience across multiple disciplines. Each of our directors will stand for election annually and must be elected by a majority of shares voted.

2 2025 PROXY STATEMENT |

Corporate Responsibility and Sustainability Highlights

Gulfport is proud to play its part in the responsible and efficient development of domestic natural gas which is critical to our country’s economic success as it provides the primary fuel for efficient power generation in the United States. We strive to reduce our environmental impact, to invest in our people and communities and to prioritize our dedication to environmental stewardship in everything we do.

We have identified several key areas where our business could have an impact on the communities where we operate, including: greenhouse gas emissions, waste and spills, water usage, health, safety and environmental (“HSE”) protection, employee training and education, and community involvement. Our Board Nominating, Environmental, Social and Governance Committee oversees environmental, safety, social, sustainability and governance (“ESG”) matters. Continuously improving our HSE performance remains a top priority. Our HSE performance also directly impacts the compensation of all our employees as it is one of the performance goals included in our cash incentive compensation plan. We believe having measurable HSE metrics as part of our incentive compensation program leads to improved accountability and reinforces our cultural focus on operating safely and protecting employees, the environment and the communities in which we operate.

Environmental Stewardship. Environmental stewardship serves as the foundation for our climate risk strategy. We are dedicated to delivering cleaner, safer, more affordable and reliable energy while working to reduce our impact on the environment. Gulfport strives to minimize our environmental impact by:

• Conducting annual recertification of all Appalachian gas with an independent auditor.

• Retrofitting natural gas pneumatic devices with compressed air or other non-gas venting devices.

• Designing future pad sites with compressed air pneumatic devices.

• Employing air quality programs and operating practices to ensure that we comply with or exceed regulations.

• Investing in and implementing technology to reduce emissions, waste and our physical footprint on drilling locations.

• Selecting and designing our well sites to minimize impacts to sensitive habitats and surrounding areas.

• Returning to existing locations for new development, creating opportunities to utilize existing facilities and minimizing surface disturbances.

• Reducing water disposal volumes and freshwater consumption through water re-use or water sharing agreements with other operators.

• Testing spill prevention and response programs to confirm equipment is properly maintained.

Gulfport is a long-standing member of The Environmental Partnership. The organization is comprised of stakeholders in the oil and natural gas industry who are committed to continuous environmental improvement. The Environmental Partnership’s primary focus is reducing methane and volatile organic compound emissions. Gulfport also developed an Environmental Policy supporting its commitment to operational excellence, compliance and environmental awareness. Gulfport’s Environmental Policy fosters environmental awareness and serves as a guide for employee behavior. All employees are expected to act and make decisions within the guidelines of the policy to ensure our business complies with local, state and federal environmental laws and regulations. Gulfport employees and contractors are expected to protect the environment, limit spills and discharges, manage waste responsibly and reduce emissions.

Safety. Safety is the number one priority for all Gulfport employees and contractors. Gulfport provides comprehensive safety training to employees and contractors and is fully committed to a safe working environment. We utilize and apply performance metrics to drive and improve safe operations. Gulfport has designed and instituted emergency response and business continuity plans to address incidents involving operational disruptions, pandemics and natural disasters. These measures include prompt notification procedures enabling Gulfport personnel to quickly evaluate and mitigate risks. Limiting safety incidents is included as part of our incentive compensation programs to ensure we train and hold our employees accountable for operating safely.

| 2025 PROXY STATEMENT 3

Corporate Responsibility and Sustainability Highlights |  |

WORK SAFE

Gulfport’s Work Safe Program is behaviorally based and focuses on twelve rules derived from Company policies (critical tasks) and cultural conditions linked to serious safety incidents in our industry. Critical Task Rules require specific operating procedures to mitigate hazardous work site conditions and complete work safely. Cultural Condition Rules are defined as work site conditions or human behaviors that have been linked to the root cause of most incidents. Employees and contractors are expected to apply and follow the requirements that coincide with the twelve rules. We continue educating employees and contractors on this program through safety meetings and training programs. Our goal is to not only improve our safety performance but to proactively prevent incidents before they occur.

Stop Work is one of the Work Safe Program’s critical tasks. Our Chief Executive Officer, John Reinhart, signed and communicated a Stop Work Authority and Obligation letter to the Company’s employees and our contractors. This letter outlines Gulfport’s commitment to health, safety and the environment and provides the expectation and support to Gulfport employees and contract partners to stop work when conditions warrant. Every person on a Gulfport work site has the authority — and obligation — to stop any work that may cause an unsafe condition, create personal risk, or harm the environment.

Health, Safety & Environment Highlights for 2024:

• Achieved overall “A” rating for Appalachia assets from MiQ for second consecutive year.

• Conducted Company’s first climate risk assessment and integrated climate-related risk into Enterprise Risk Management program.

• Reduced combined total recordable incident rate by 74% compared to 2021.

• Invested in and implemented technology to reduce emissions, waste and our physical footprint on drilling locations.

• Reduced water disposal volumes and freshwater consumption through water re-use or water sharing agreements with other operators.

• Progressed in multi-year program to convert natural gas process controllers with compressed air or other non-gas venting devices across our operations to reduce methane emissions.

Human Capital. Gulfport’s employees are its most important asset. We believe the differences among our workforce make us stronger as a Company, and we prioritize attracting and recruiting highly qualified candidates with varied backgrounds and experiences. We remain committed to outreach efforts to keep our candidate pool as large as possible so that we continue to hire and retain the best, highly qualified, and experienced professionals in our industry. We regularly evaluate our pay practices and benefit offerings to ensure they remain fair and competitive. We also offer our employees and managers development training and provide access to the resources they need to execute at a high level. We also offer ongoing and continuous training on our workplace policies. We encourage all employees to provide feedback and ideas on how Gulfport can continuously improve as an organization. We require all employees to sign a commitment indicating they will speak up if they observe or become aware of any actions that are inconsistent with our core values, our Code of Business Conduct and Ethics, or other Company policies. We are also committed to supporting veterans through our recruiting and hiring efforts, and we support several causes that assist veterans and active-duty military personnel.

In 2024, all employees participated in multiple and varied training courses on our Business Code of Conduct and Ethics, Company policies, and topics specifically related to employees’ job performance, health, and safety. We understand that a workplace environment that embraces continuous improvement and incorporates different ideas and perspectives is a healthy environment and one that provides the best solutions to complex challenges.

Board Composition. Our Nominating, Environmental, Social and Governance Committee is dedicated to attracting and recruiting the most qualified candidates. The Committee values varied experiences and backgrounds and adopted a Board Diversity Policy. The policy requires that the Committee include a broad range of candidates in all director searches, taking into account gender, race, ethnicity, background, age, thought and tenure on our Board (in connection with the consideration of the renomination of an existing director). Gulfport’s current Board has over 40% of our directors identifying as gender or ethnically diverse.

Human Rights Policy. Gulfport is committed to serving as a positive force in its communities, and the Company remains dedicated to upholding the highest standards of human rights, clearly defined in our Human Rights Policy.

Corporate Governance Highlights

We believe effective corporate governance requires regular constructive discussions with our stakeholders and we focus our sustainability priorities and disclosures on the issues that are most important to them.

COMPENSATION HIGHLIGHTS

Stockholder Engagement and Annual Say-On-Pay Advisory Vote

At the Annual Meeting, our stockholders will again have an opportunity to cast an advisory Say-On-Pay vote on the compensation paid to our Named Executive Officers (NEOs) as described in this proxy statement. The details of the executive compensation program and its pay-for-performance alignment are discussed in the “Compensation Discussion & Analysis (CD&A)” on page 25 of this proxy statement.

Gulfport Energy engages in discussions with our stockholders at investor conferences and through direct calls and meetings with the Company’s management team that represented over 60% of the shares outstanding. Through these conversations our stockholders emphasized their expectation that our compensation programs should be designed to focus our executive team on driving results that ensure the financial health of the organization while also driving long-term stockholder value. Specifically, after carefully considering input from stockholders, the Company took the following actions in 2024:

• Utilized performance-based and time-based equity awards in the form of performance-based restricted stock units tied to relative total shareholder return (“TSR”) and absolute total shareholder return, vesting over a three-year performance period; 60% of all equity awards to NEOs were performance-based.

• Adjusted performance incentive opportunities and long-term equity award targets to closely align our executives’ financial interests with those of our stockholders and to continue to link a large portion of executives’ compensation to the performance of our stock and our operational performance.

• Continued utilizing metrics in the annual incentive plan to include measures directly tied to the financial health of the Company, including production per day, capital expenses, lease operating expenses, free cash flow generation, and specific and quantifiable health, safety, environmental and social metrics.

• Provided robust disclosure of our performance metrics and targets for both performance-based cash and equity awards.

All Directors attended our 2024 Annual Meeting of Shareholders.

Code of Business Conduct and Ethics

We have adopted a Code of Business Conduct and Ethics designed to help directors and employees resolve ethical issues. Our Code of Business Conduct and Ethics applies to all directors and employees.

NOMINATING PROCESS FOR DIRECTORS, DIRECTOR QUALIFICATIONS AND REVIEW OF DIRECTOR NOMINEES

Director Qualifications

As provided by the Nominating, Environmental, Social and Governance Committee’s charter, the Committee identifies, investigates, and recommends candidates to our Board of Directors with the goal of creating a balance of knowledge, experience, and backgrounds. The Committee identifies candidates using third-party search firms, as well as through the extensive networks of our directors and management team in the oil and natural gas industry.

It is our policy that potential directors should possess the highest personal and professional ethics, integrity and values and be committed to representing the interests of our stockholders. In addition to reviewing a candidate’s background and accomplishments, candidates are reviewed in the context of the current composition of our Board of Directors, the skills necessary to provide effective oversight in critical areas and the evolving needs of our business. It is the policy of our Board of Directors that, at all times, at least a majority of its members meet the standards of independence promulgated by the NYSE and the SEC and that its members reflect a range of talents, skills and expertise, particularly in the areas of accounting and finance, management, leadership and oil and gas-related industries sufficient to provide sound and prudent guidance with respect to our operations and the interests of our stockholders.

Nomination Process

Our Board of Directors will consider stockholder nominations for director candidates upon written submission to our Chief Legal and Administrative Officer and Corporate Secretary along with, among other things, the nominee’s qualifications and certain biographical information regarding the nominee, the nominee’s written consent to serve as a director if elected and being named in the proxy or information statement and information regarding the status of the stockholder submitting the recommendation, all in the manner required by the Second Amended and Restated Bylaws of the Company (the “Bylaws”) and the applicable rules and regulations promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Following verification of the stockholder status of the persons proposing candidates, recommendations will be aggregated and considered by our Board of Directors at a regularly scheduled or special Board meeting. If any materials are provided by a stockholder in connection with the nomination of a director candidate, materials will be forwarded to our Board of Directors. See “Submission of Future Stockholder Proposals” below for additional detail regarding submitting director nominees.

Our Board of Directors may also review materials provided by professional search firms or other parties in connection with a nominee who is not proposed by a stockholder. In evaluating nominations, our Board of Directors will seek to achieve a balance of knowledge, experience and backgrounds on the Board. To be nominated to serve as a director, a nominee need not meet any specific minimum criteria. Our Board of Directors uses the same criteria for evaluating candidates nominated by stockholders as it does for those proposed by current Board members, professional search firms and other people. After completing its evaluation, our Board of Directors approves the final slate of director nominees.

Our Nominating, Environmental, Social and Governance Committee approved the director nominees submitted for election at the Annual Meeting. Each nominee brings a strong and unique background and set of skills to our Board of Directors, giving our Board of Directors competence and experience in a variety of areas, including corporate governance and Board service, executive management, the oil and natural gas industry, accounting and finance and risk assessment and management.

NOMINATING PROCESS FOR DIRECTORS, DIRECTOR QUALIFICATIONS AND REVIEW OF DIRECTOR NOMINEES |  |

Summary of Director Qualifications and Experience

The chart below identifies the balance of skills and qualifications each director nominee brings to the Board.

We believe the combination of the skills and qualifications shown below demonstrates how our Board is well positioned to provide strategic advice and effective oversight to our management.

DIRECTOR LEADERSHIP STRUCTURE

Board Chair

Timothy Cutt served as Board Chair and CEO beginning on May 17, 2021. Effective January 24, 2023, the positions of Board Chair and Chief Executive Officer are held by two different individuals, and the Board Chair is a non-executive position elected from among the directors by the Board. Separating the positions of Board Chair and Chief Executive Officer allows our Chief Executive Officer to focus on business development strategies as well as our day-to-day business and operations, while permitting our Board Chair to lead the Board in its fundamental role of providing advice to and oversight of management. The Board Chair provides leadership to our Board of Directors and works with the Board of Directors to define its structure and activities in the fulfillment of its responsibilities.

The duties of the non-executive Board Chair include:

• Presiding at meetings of our Board of Directors and stockholders.

• Setting Board agendas with input from other members of the Board and our management.

• Facilitating communication among, and information flow to, directors.

• Calling special meetings of our Board of Directors and stockholders.

• Advising and counseling our Chief Executive Officer and other officers.

Lead Independent Director

The Board has appointed Mr. Wolf to serve as Lead Independent Director with responsibilities typically performed by an independent Chair, including acting as Chair at meetings of the Board of Directors when the Board Chair is not present. The Lead Independent Director role is a highly versatile intermediary between the Board Chair and the Board’s stakeholders. In normal times they contribute to the good relationships and functions of the Board, and in periods of stress the Lead Independent Director is expected to assist in facilitating the resolution of any situation. Mr. Wolf also is a member of each of the Board’s Committees and acts as Chair at Committee meetings when the respective Committee Chair is not present.

Directors

We believe that our directors bring a broad range of leadership experience to the boardroom and regularly contribute to the thoughtful discussion involved in effectively overseeing the business and affairs of the Company. We believe that the atmosphere of our Board is collegial, that all Board members are well engaged in their responsibilities and that all Board members express their views and consider the opinions expressed by other directors. Five out of seven director nominees are independent under NYSE listing standards and SEC rules. We believe that our independent directors have demonstrated leadership in business enterprises and are familiar with Board processes. Our independent directors are involved in the leadership structure of our Board by serving on our Audit, Nominating, Environmental, Social and Governance and Compensation Committees, comprised entirely of independent directors and each having an independent chair.

Committee Chairs

Specifically, our Audit Committee Chair oversees the accounting and financial reporting processes and compliance with legal and regulatory requirements. Our Compensation Committee Chair oversees our compensation policies and practices and their impact on risk and risk management. The Chair of our Nominating, Environmental, Social and Governance Committee oversees our practices relating to health, safety and environmental protection, as well as social and governance matters. Our Nominating, Environmental, Social and Governance Committee Chair also monitors matters related to Board and Committee composition, Board performance and best practices in corporate governance. Each Committee Chair provides independent leadership for the purposes of many important functions delegated by our Board of Directors to such Committee.

|  | 2025 PROXY STATEMENT 21

BOARD OF DIRECTORS’ ROLE IN RISK OVERSIGHT

While our management team is responsible for the day-to-day management of risks, the Board of Directors has primary responsibility for risk oversight. Boards typically exercise this oversight during regular Board meetings, but our Board of Directors also maintains constant and open dialogue with management and reviews and monitors key processes. As a result, they are better able to respond to emerging risks and to influence our strategy to address those risks.

While our Board of Directors is responsible for risk oversight at the Company, our three Committees assist the Board in fulfilling its oversight responsibilities in the areas of risk below:

Committee | Risk Areas of Focus
Audit | • Cybersecurity • Financial Reporting • Internal Controls • Legal Compliance • Regulatory Compliance • Reserves Reporting • Risk Management
Compensation | • Compensation Policies • Executive Performance
Nominating, Environmental, Social and Governance | • Board Organization • Climate • Corporate Governance • Environment • Government Relations • Membership • Political Contributions • Public Health • Safety • Structure • Succession Planning

COMPENSATION DISCUSSION AND ANALYSIS

Letter from the Compensation Committee

2024 was defined by execution, operational excellence and strong financial results for Gulfport Energy. The Company delivered on all fronts, highlighted by our high-quality resource base and the continued improvement of development efficiencies throughout the year. The Company delivered net production in line with initial expectations while executing at the low end of its initial capital expenditures expectations. The 2024 development program led to meaningful adjusted free cash flow generation, and after adjusting for cash flow utilized for attractive discretionary acreage acquisitions, Gulfport allocated approximately 96% of adjusted free cash flow to repurchasing our common stock during 2024. All of this was achieved while maintaining our strong balance sheet, ample liquidity and financial leverage below one times. The Company’s accomplishments were realized by the investment community and Gulfport’s stock price appreciated over 38% during 2024, outperforming the S&P 500 which appreciated by approximately 25% and Gulfport’s 2024 compensation peer group average appreciation of approximately 10%.

From an executive compensation perspective, we were able to set realistic, challenging targets for our short and long-term incentive plans. We were pleased to see the financial and operational results exceed our expectations. We were able to deliver on our compensation strategy of providing compensation opportunities that were tied to Company performance. Our philosophy is to remain competitive within the oil and gas industry for similarly situated operations.

Please review the Compensation Discussion and Analysis, where we explain how we tie pay and performance together to reward our executives. We are confident our shareholders will once again agree with the compensation decisions we made regarding our executive team as they overwhelmingly did based on the 97.8% of votes we received on our 2024 Say-On-Pay vote.

Thank you for your confidence and investment in Gulfport Energy.

• Established annual performance bonus opportunities and long-term equity award targets to closely align our NEOs’ financial interests with those of our stockholders and to continue to link a larger portion of NEOs’ compensation to the performance of our stock and operational performance.

• Selected metrics in our annual incentive plan tied to the financial health of the Company and specific and quantifiable health, safety and environmental metrics.

• Continued to provide robust disclosure of our performance metrics and targets for both performance-based cash and equity awards.

• Utilized formal stock ownership guidelines to ensure our Board of Directors and executive officers own a stake in the Company that is sufficient to align their interests with their fellow stockholders.

|  | EXECUTIVE SUMMARY

The Compensation Committee will continue to consider the feedback from our stockholders when making compensation decisions for our NEOs.

Practices We Follow
🗸 | Incentives Aligned with Stockholders. All long-term equity incentive awards granted in 2024 were in the form of either time-based or performance-based restricted stock units, and the performance-based restricted stock units vest based on absolute and relative TSR, providing strong alignment between management and stockholders.
🗸 | NEO pay is at-risk. A significant portion of executive compensation is conditioned on the achievement of pre-determined operational, capital efficiency and safety and environmental targets, as well as absolute TSR and TSR measured against a broad peer group of exploration and production companies.
🗸 | Performance-based awards are prevalent. 60% of the NEOs’ equity incentive awards consisted of performance-based equity awards that vest based on absolute and relative TSR metrics measured over a three-year performance period.
🗸 | Robust disclosure of our performance metrics and targets. We provide detailed disclosure of our performance metrics in our CD&A.
🗸 | Balanced approach to executive compensation. We view the combination of long-term equity and short-term cash compensation, prioritizing long-term equity compensation and focusing on performance-based equity and cash compensation when analyzing total compensation plans.
🗸 | Ownership guidelines. We have robust stock-ownership guidelines for directors and executive officers.
🗸 | Risk Management. We perform annual enterprise risk assessments to ensure our compensation programs do not create undue risk to the business.
🗸 | Clawback and recoupment processes. We maintain a clawback policy that allows us to recover incentive compensation in certain circumstances.
🗸 | Executive Compensation best practices. The Compensation Committee uses an independent compensation consulting firm to provide input into our executive compensation programs.

Practices We Prohibit
û | Minimum bonuses or guarantees. The Company does not guarantee minimum bonuses and relies on target achievement to determine annual bonus payments.
û | Single-trigger vesting of equity awards. The Company does not allow for single-trigger vesting of equity awards in connection with a change of control.
û | Providing tax gross-ups. No tax gross-up payments have been provided to our NEOs.
û | Hedging or pledging Gulfport Energy Stock. The Company does not allow hedging or pledging of Gulfport securities by our NEOs or directors.
û | Liberal share recycling. We do not allow liberal share recycling in our stock incentive plan.
û | Holding Gulfport Energy stock in a margin account. The Company does not allow securities to be held in a margin account by our NEOs or directors.
û | Excessive perquisites or executive benefits plans. No pension, supplemental executive retirement plan or excessive perquisite plans are made available to our NEOs.
û | Repricing of Stock Options. The Company did not grant stock options in 2024, currently has no plans to grant stock options in the future and would not reprice any outstanding stock options that might be outstanding.

EXECUTIVE SUMMARY |  |

Compensation Aligned with Performance

The Compensation Committee believes that executive compensation should be designed to deliver competitive pay when performance targets are achieved, and when business results exceed targets, executives should share in those rewards based on their efforts. If the Company does not achieve established performance goals, the executive team should receive pay that reflects that lower achievement. We believe this pay-for-performance alignment is working as realized pay for 2024 was above target levels due to exceeding pre-set performance goals and strong shareholder returns. The Company delivered 2024 net production in line with initial expectations while executing at the low end of its initial capital expenditures expectations. The 2024 development program led to meaningful adjusted free cash flow generation, and after adjusting for cash flow utilized for attractive discretionary acreage acquisitions, Gulfport allocated approximately 96% of adjusted free cash flow to repurchasing our common stock during 2024. All of this was achieved while maintaining our strong balance sheet, ample liquidity and financial leverage below one times. The Company’s accomplishments were realized by the investment community and Gulfport’s common stock appreciated over 38% during 2024, outperforming the S&P 500 which appreciated by approximately 25% and Gulfport’s 2024 compensation peer group average appreciation of approximately 10%.

The majority of our current NEO’s total compensation is dependent on the successful achievement of Company results as measured by either short-term incentive plan metric achievement or achievement of performance measures and stock price appreciation of the Company’s common stock. The target total direct compensation of our NEOs is largely influenced by pay-at-risk or variable compensation, tying the pay of the executive to the Company’s performance and share price of the Company’s common stock. Short-term incentive plan targets for 2024 were exceeded, resulting in actual awards to executives that were higher than target amounts and demonstrating the alignment between performance and pay.

Stockholder Engagement and Annual Say-On-Pay Advisory Vote

The Compensation Committee is committed to engaging with our stockholders to understand their expectations for executive compensation, corporate governance and safety, environmental and other social responsibility matters at Gulfport Energy. In 2024, 97.8% of shareholders voted to approve the Company’s executive compensation program and practices. The Company is pleased that shareholders continue to strongly support our executive pay program and remains committed to meeting with stockholders to solicit feedback on our executive compensation practices in the future. Based on the results of the Company’s last advisory vote on the frequency of future Say-On-Pay votes at the Company, also known as a say-on-frequency vote, the Company will continue to hold annual Say-On-Pay votes until the Company’s next say-on-frequency vote in 2029.

The Company held discussions with stockholders representing over 60% of shares outstanding. Through these conversations, our stockholders emphasized their expectation that management should be focused on driving results that deliver stockholder value. Our stockholders agree that executives should not be paid at target levels unless financial targets are achieved and expressed a desire to see specific and measurable targets for the year. Stockholders also expressed a desire for executives to have exposure to the absolute return of the Company’s common stock without regard to broader market fluctuation. The Company is confident that the metrics selected for both short-term and long-term incentives are appropriate and continue to align with shareholder preferences. Changes were made to metrics selected in the annual incentive plan to incorporate environmental, safety and other social practices for 2024.

After carefully considering input from stockholders, the Company took the following actions in 2024:

• Granted performance-based equity awards in the form of performance-based restricted stock units tied to absolute and relative TSR, vesting over a three-year performance period, comprising at least 60% of all the equity awards granted to our NEOs.

• Utilized short-term incentive opportunities and long-term equity award targets that closely align our NEOs’ financial interests with those of our stockholders and continue linking a larger portion of NEOs’ compensation to our operational and share price performance.

• Provided robust disclosure of our performance metrics and targets for both performance-based cash and equity awards.

• Continued utilizing metrics in the annual incentive plan to include measures directly tied to the financial health of the Company, including production per day, capital expenses, lease operating expenses, free cash flow generation, and specific and quantifiable health, safety, environmental and social metrics.

The Compensation Committee will continue to consider the feedback from our stockholders when making compensation decisions for our NEOs.

EXECUTIVE COMPENSATION PHILOSOPHY AND COMPONENTS

Philosophy and Objectives

Our executive compensation philosophy is guided by the following objectives:

EXECUTIVE COMPENSATION
Alignment with Stockholder Interests | By providing the majority of compensation in long-term equity awards, stressing pay for performance, managing dilution to our stockholders and encouraging an ownership culture, we aim to align the interests of our executives with those of our stockholders.
Pay for Performance | The Company is focused on rewarding performance by creating incentive awards based on achievement of clearly defined performance targets. A significant portion of our NEOs’ compensation is delivered in long-term incentives, making our NEOs’ realized total direct compensation heavily dependent upon Company performance and stock price.
Competitive Compensation | The Company believes it is imperative to maintain compensation programs competitive with our peer group to attract, retain and motivate executives and our future leaders in a way that is in line with the compensation of executive positions at similar companies.

Our executive compensation programs play a key role in helping us achieve our business objectives and effectively reward executive officers for our Company’s annual and long-term performance and individual contributions to performance.

Total Direct Compensation Components for 2024

| Pay Element | Vehicle | Philosophy
| Benefits | • Health, dental and vision insurance available to all employees. 401K program, vacation policy and disability plans to provide income replacement due to long-term or short-term illness | • Provide core health, welfare and retirement savings plans for executives. Provide substantially the same programs for all employees with minimal executive perquisites.
Base Pay | • Base pay rates that are reviewed annually and subject to Compensation Committee recommendations | • Provide compensation that is competitive with the median peer group practices. Base pay levels reflect the unique skills and abilities of our executives and accounting for the primary duties associated with the executive’s role.
Short-Term Incentive | • Annual incentive opportunity to earn a percentage of base pay based on annual operating objectives | • Provides incentive opportunities that approximate median peer group pay when performance targets are achieved. When targets are exceeded, the executive should be rewarded for their efforts with pay that exceeds the median of the peer group. When targets are not achieved, the executive should earn pay levels below the median of the peer group.
Long-Term Incentives | • Time-Based Restricted Stock Units | • Time-based restricted stock unit grants that vest in equal annual installments over 3 years. If the executive remains with the Company, the executive experiences either increased or decreased pay levels based on the performance of the stock price, fully aligning our executives with the return of the Company’s stock.
• Performance-Based Restricted Stock Units | • Performance-based restricted stock units that are tied to total shareholder return over a performance period that aligns stockholders and executive interests, providing an additional incentive opportunity for the executive when absolute and/or relative returns exceed those of our peer group.

EXECUTIVE SUMMARY |  |

Determining our Executive Compensation

Benchmarking Against Our Compensation Peer Group

Gulfport utilizes a peer group of companies, or the Compensation Peer Group, as a reference point when establishing both compensation levels for NEOs as well as program structures, to achieve competitiveness in the market.

2024 Compensation Peer Group

The Compensation Committee engaged its independent consultant, WTW, formerly Willis Towers Watson, to establish the appropriate peer group for executive compensation for 2024. Potential peers were identified using revenue, primary business, equity value/debt ratio, other relevant financial metrics (EBITDA, market capitalization, assets, net income, etc.), gas weighting and the number of operations/regions. Upon review and analysis of potential peers using these criteria, the peers below were identified as both suitable and relevant to comprise the Company’s 2024 peer group. The revision of the Compensation Peer Group resulted in relative alignment of Gulfport’s key metrics at the time the peer group was established.

2024 Compensation Peer Group
Berry Corporation CNX Resources Corporation Matador Resources Company SilverBow Resources, Inc.* Vital Energy, Inc. | Callon Petroleum Company Comstock Resources, Inc. Murphy Oil Corporation SM Energy Company | Civitas Resources, Inc.* Magnolia Oil & Gas Corporation Range Resources Corporation Talos Energy Inc.

* Denotes a new peer added in 2024.

In general, and consistent with a performance-based compensation philosophy, the Compensation Committee seeks to establish executive base pay within a competitive range of the appropriate peer group median, with an opportunity to earn greater overall compensation in the event it is warranted by our performance. The exact level of targeted compensation for each NEO varies based on the individual’s role in Gulfport, experience, and contribution to our success. For benchmarking purposes, the Compensation Committee compares the total compensation for each NEO position to the compensation paid for similar positions by companies in our Peer Group, as set forth in those companies’ proxy statements for the prior year. WTW proposes companies to be included in the Compensation Peer Group and the methodology for selecting that peer group and may consult with management to confirm that the most appropriate companies are selected. The Compensation Committee then reviews and, as it may deem appropriate, approves the Compensation Peer Group for the applicable compensation year. The companies identified were at their time of selection, in the view of the Compensation Committee the best and most appropriate companies for benchmarking compensation within our industry. The Compensation Committee will continue to review and monitor the Compensation Peer Group annually and select peers based on appropriate screening criteria, metrics and competition for executive talent. The Compensation Committee also uses industry-specific survey data as an additional reference point to assist in the compensation decision-making process.

32 2025 PROXY STATEMENT |  |

|  | EXECUTIVE SUMMARY

PROCESS FOR DETERMINING EXECUTIVE COMPENSATION

The Compensation Committee of our Board of Directors oversees our compensation programs for executive officers and all employees. During 2024, the Compensation Committee was comprised of Jason Martinez (Chair), David Reganato, Mary Shafer-Malicki and David Wolf. All members of the Compensation Committee are independent directors.

The Role of Our Compensation Committee

The Compensation Committee generally reviews and typically makes its decisions regarding the annual compensation of our NEOs at its regular meetings in the first half of each year. These decisions include:

• Approving base salaries, target, annual cash incentive levels and long-term equity-based incentive levels.

• Establishing applicable performance objectives for performance-based awards.

• Granting long-term equity-based incentive awards and determining the types of awards for the current year.

• Certifying annual performance-based cash incentive awards and performance-based long-term incentive award payouts.

The Compensation Committee may also adjust compensation as necessary at other times during the year, such as in the case of promotions, other changes in employment status and significant corporate events, as well as to reflect changing market conditions or for other competitive purposes.

In making its decisions, the Compensation Committee assesses each NEO’s impact during the year and overall value to Gulfport, specifically considering the NEO’s contribution to the growth of Gulfport’s value, operational and financial performance, performance in the NEO’s primary area of responsibility, impact on strategic initiatives, recommendations of our independent compensation consultant, the NEO’s role and trajectory in succession planning and development, recommendations from our CEO with respect to our other NEOs and other intangible qualities that contribute to corporate and individual success.

The Role of our CEO

The Compensation Committee evaluates our CEO based on the Company’s performance metrics, leadership roles as a member of the Board and our lead representative to the investment community and other criteria. The CEO’s total compensation package is determined by the Compensation Committee, based upon its evaluation and input from our independent compensation consultant. Our CEO’s compensation ultimately reflects Gulfport’s performance, personal performance, competitive industry practices and the terms of our employment arrangement with the CEO.

Our CEO evaluates each of the other NEOs and makes compensation recommendations to the Compensation Committee. In developing recommendations, the CEO considers the recommendations of the Compensation Committee’s independent compensation consultant, as well as each NEO’s performance against the Company performance metrics and contribution to Gulfport’s performance. The independent compensation consultant reviews and provides comments to the Compensation Committee based on our CEO’s recommendation with respect to our NEOs, other than our CEO. Our CEO does not participate in deliberations or decisions concerning his own compensation.

The Role of the Compensation Consultants

For 2024, the Compensation Committee retained the service of WTW to perform executive compensation advisory services, reporting directly to the Compensation Committee Chair. The Compensation Committee determined that the expertise that WTW had in the executive compensation consulting space with other similar Exploration and Production (“E&P”) companies, in addition to deep insights into compensation practices of other similar companies, was critical for Gulfport Energy. WTW provided contemporary best practices in base pay administration, short-term incentive plan design and long-term incentive plan design. This information, which included reviews of peers, a broader E&P group and general industry practices, was used by the Compensation Committee to determine base salary, short-term incentives and long-term incentives for our executives.

|  | 2025 PROXY STATEMENT 33

EXECUTIVE SUMMARY |  |

WTW also provided support with regulatory and other considerations that affect compensation programs generally, as requested by the Compensation Committee, as well as assistance in preparation of the CD&A.

WTW reported exclusively to the Compensation Committee, with respect to the services described above. During 2024, WTW provided other non-executive compensation consulting services to us, but the total fees for such services did not exceed $120,000. The Compensation Committee reviewed the independence of WTW and determined that there were no conflicts of interest because of the Compensation Committee’s engagement of WTW.

The Compensation Committee evaluates the independence of its compensation consultant(s) on an ongoing basis.

2024 COMPENSATION PROGRAM DESCRIPTION

Base Salary

The Compensation Committee engaged WTW to review the overall competitiveness of our executive compensation program for 2024, with a continued focus on ensuring the alignment of management compensation with performance and the achievement of Gulfport’s long-term goals. The Compensation Committee reviews NEO base salaries on an annual basis, with a goal of providing market-competitive, fixed cash compensation. The Compensation Committee assesses comparable salary information provided by its independent compensation consultant as a factor when determining the base pay for NEOs.

Other factors the Compensation Committee considers in determining base pay for each of the NEOs include, but are not limited to: the NEO’s responsibilities, experience, leadership, potential future contribution and demonstrated individual performance. The relative weighting of these factors varies by NEO depending on their position and responsibilities. In March 2024, the base salaries of the executive team were reviewed, and changes were made to certain executives’ base salaries after reviewing the current labor market for executive talent, performance and other job-related factors for each executive. A summary of the changes is reflected in the table below.

Name | Base Salary YE 2023 | Percent Increase (%) | Base Salary YE 2024
John Reinhart | $785,000 | 14.6% | $900,000
Michael Hodges | $485,000 | 6.2% | $515,000
Patrick Craine | $485,000 | 3.1% | $500,000
Matthew Rucker | $390,000 | 12.8% | $440,000
Michael Sluiter | $390,000 | 6.4% | $415,000

Annual Incentive Awards

The Compensation Committee established a performance-based annual cash incentive program for 2024 that tied our NEOs’ compensation directly to pre-established performance metrics. Targeted annual incentive award levels were based on market information supplied by the independent compensation consultant. Individual awards may be decreased at the discretion of the Compensation Committee based on overall corporate performance for the year and other considerations.

2024 Annual Short-Term Incentive (“STI”) Metrics and Annual STI Payments

The Compensation Committee determined that the appropriate Key Performance Indicators (“KPIs”) for the 2024 STI plan should focus primarily on generating adjusted free cash flow and executing certain strategic objectives that were important to the continued success of the organization and were responsive to shareholder feedback. After reviewing the operating and financial targets for 2024 with the Board of Directors, the Gulfport Energy executive management team and the independent compensation advisor, the Compensation Committee approved performance targets accordingly. The KPIs included thresholds, targets and maximums that were based on predetermined financial and key performance metrics.

34 2025 PROXY STATEMENT |  |

|  | EXECUTIVE SUMMARY

The financial metrics chosen were generally common measures in the oil and gas industry and were viewed as measures of success by our shareholders. The Compensation Committee also believed it was critical to focus on other strategic initiatives that while not directly measured in financial terms, are key indicators of successful companies in the oil and gas industry. Total Recordable Incident Rate (“TRIR”) and spills are common measurements and targets that reflect either industry benchmark information (TRIR) or improvement over prior results (spills). The Compensation Committee also adopted a set of strategic initiatives that focused on environmental and corporate and social governance activities. Specifically, the organization would be measured on making substantial improvement in the areas of Appalachian gas certification with an “A” grade from MIQ, completing a successful organizational restructuring, and retrofitting natural gas pneumatics with air in the SCOOP.

In July of 2024, after performance targets for the annual STI had been set in February of 2024, the Board of Directors made a strategic decision to both increase the Company’s 2024 capital program and defer targeted completions activity to later in the year after management’s operational efficiencies provided the opportunity to accelerate activity. Realizing that these additional expenditures and the deferred production were not included in the initial target setting process, the Board of Directors adjusted the 2024 performance metrics to account for these changes in the 2024 incentive payment results.

At the completion of the performance period ending December 31, 2024, the Compensation Committee reviewed financial and operating results and the attainment of key performance indicators and approved 2024 STI payout results based on those achievements. This achievement resulted in an overall payout of 150% of target awards. Below is a summary of KPIs and results for the 2024 plan year.

2024 STI Metrics

| Weighting | Threshold | Target | Maximum | 2024 Actual(2) | 2024 Approved Payout(2)
Production (MMcfe/day) | 20% | 1,035 | 1,057 | 1,090 | 1,060 | 22%
Capex ($MM) | 20% | $435 | $408 | $375 | $385 | 34%
LOE per Mcfe ($/Mcfe) | 15% | $0.20 | $0.19 | $0.17 | $0.18 | 22%
Adjusted Free Cash Flow ($MM)(1) | 15% | $190 | $231 | $295 | $261 | 22%
TRIR | 10% | 0.8 | 0.6 | 0.4 | 0.3 | 20%
Spills | 10% | 6 | 4 | 2 | 1 | 20%
Strategic Initiatives | 10% | Qualitative | 10%
Total Achievement Percentage |  |  |  |  |  | 150%

(1) Adjusted Free Cash Flow is a non-GAAP measure defined as net cash provided by operating activities from the Company’s Consolidated Statement of Cash Flows less the sum of changes in operating assets and liabilities included in the operating activities section of the Consolidated Statement of Cash Flows less non-recurring general and administrative and other expenses from the Consolidated Statement of Operations less incurred capital expenditures and capitalized expenses. Adjusted Free Cash Flow was calculated assuming realized commodity pricing received throughout the year was consistent with the forward curve pricing used to set the approved Adjusted Free Cash Flow Metric in February of 2024.

(2) The impact of the changes to the Company’s 2024 capital program on the 2024 incentive payment results as described above consisted of increased capital expenditures of $5 million, which reduced the 2024 actual Capex metric and increased the 2024 Adjusted Free Cash Flow metric results, and decreased production of 6 MMcfe/day, which increased the 2024 actual production metric and the Adjusted Free Cash Flow metric results, and decreased the LOE per Mcfe metric.

EXECUTIVE SUMMARY |  |

2024 Target Annual STI Opportunities and Actual Annual STI Payments

The Compensation Committee established the target annual cash STI opportunity for each of the NEOs, taking into consideration the terms of any applicable employment agreement, and approved the following cash payments based on the Company’s 2024 results performance as described above.

2024 INCENTIVE COMPENSATION PLAN

Name | 2024 Incentive Compensation Program Incentive Target | Actual Annual Incentive Achievement (as % of Target Annual Incentive) | Actual Incentive Earned for 2024
John Reinhart | $1,080,000 | 150% | $1,620,000
Michael Hodges | $ 515,000 | 150% | $ 772,500
Patrick Craine | $ 450,000 | 150% | $ 675,000
Matthew Rucker | $ 374,000 | 150% | $ 561,000
Michael Sluiter | $ 311,250 | 150% | $ 466,875

Long-Term Incentive Awards

Each year we grant our NEOs long-term incentive awards, that have historically consisted of equity-based awards. The Compensation Committee determines the amount of these awards, as well as the mix of equity vehicles. The objectives of our long-term incentive plan are to: (i) create significant alignment between the interests of our NEOs and our stockholders; (ii) attract and retain the services of critical talent; and (iii) focus our executives on our sustained growth and financial success.

2024 Performance Share Unit Certification

On May 17, 2024, the Compensation Committee certified performance share units issued on July 21, 2021. WTW presented the Committee with their findings of achievement of the performance conditions during the performance period. The Committee determined that based upon the 2021 PSUs performance results that the 2021 PSUs should be paid out at 195.7% of the target amount.

The performance-based restricted stock units vest after a three-year performance period, based on the Company’s achievement of relative TSR as compared to a peer group of companies and absolute TSR, in each case, as described in the chart below.

|  | Relative TSR
> 75 th percentile of the Peer Companies | 50 th percentile – < 75 th percentile of the Peer Companies | 25 th percentile – < 50 th percentile of the Peer Companies | < 25 th percentile of the Peer Companies
Annualized Company TSR | < 5.0% | 0% | 0% | 0% | 0%
> 5.0% – 7.5% | 50% | 25% | 0% | 0%
> 7.5% – 10.0% | 125% | 100% | 75% | 50%
> 10.0% – 15.0% | 150% | 125% | 100% | 75%
> 15.0% – 20.0% | 175% | 150% | 125% | 100%
> 20.0% | 200% | 175% | 150% | 125%

36 2025 PROXY STATEMENT |  |

|  | EXECUTIVE SUMMARY

DETERMINING AWARD STRUCTURE AND SETTING THE TARGET AWARD OPPORTUNITY

The Compensation Committee considers the grant date fair value of the long-term incentive package, the package’s potential dilutive effect on our outstanding shares of common stock and the number of shares available for grant under the 2021 Incentive Plan (as defined below) in determining the aggregate number of shares to be awarded as individual long-term incentive awards for our NEOs. The Compensation Committee evaluates stockholder dilution based on equity compensation plans compared to the total amount of the Company’s outstanding common stock. In determining the appropriate long-term incentive awards to grant NEOs other than the CEO, the Compensation Committee considers the recommendations of the CEO. The Compensation Committee reviewed market values with respect to the annual long-term incentive awards granted to similarly situated executives at the Compensation Peer Group. In 2024, the Compensation Committee determined that the NEOs would receive equity grants consisting of 60% performance-based restricted stock units and 40% time-based restricted stock units. The time-based restricted stock units granted to our NEOs vest in equal annual installments over a three-year period.

The performance-based restricted stock units vest after a three-year performance period, based on the Company’s achievement of relative TSR as compared to a peer group of companies and absolute TSR, in each case, as described in the chart below.

|  | Relative TSR
> 75 th percentile of the Peer Companies | 50 th percentile – < 75 th percentile of the Peer Companies | 25 th percentile – < 50 th percentile of the Peer Companies | < 25 th percentile of the Peer Companies
Annualized Company TSR | < 5.0% | 50% | 35% | 25% | 0%
> 5.0% – 10% | 125% | 100% | 75% | 50%
> 10% – 15.0% | 150% | 125% | 100% | 75%
> 15.0% – 20.0% | 175% | 150% | 125% | 100%
> 20.0% | 200% | 175% | 150% | 125%

EXECUTIVE SUMMARY |  |

COMPENSATION POLICIES AND PRACTICES

Compensation Risk Management

The Compensation Committee continues to review the risks and rewards associated with our compensation policies and programs. We believe that our policies and programs encourage and reward prudent business judgment, encourage short-term stockholder value creation, and prioritize long-term growth by discouraging excessive risk taking. With respect to specific elements of compensation:

• Integrated Approach – Our programs balance short- and long-term incentives for our executive officers by providing an appropriate mix of fixed, performance-based, discretionary and equity compensation, with the goal of creating both short- and long-term stockholder value.

• Attract Top Talent – Annual base salaries for our NEOs do not encourage excessive risk-taking as they are fixed amounts that are subject to discretionary increases by our Compensation Committee that may be based on, among other factors, annual performance evaluations. We believe that annual base salaries are set at reasonable levels, as compared to the base salaries of similarly situated individuals at our peer group companies and therefore do not negate the effect of other compensation elements that encourage long-term service, growth and performance that may increase stockholder value.

• Support Business Objectives and Strategic Goals – Our annual incentive awards are determined based on financial, operational and strategic Company performance measures, which mitigate excessive risk-taking that could produce unsustainable gains in one area of performance at the expense of our overall long-term interests. The Company’s goals are designed to ensure a proper balance between stock performance, operational measures, financial goals and strategic goals. In addition, the Compensation Committee sets performance goals that it believes are reasonable considering our past performance, then-current business projections and market conditions.

• Pay for Performance – The Compensation Committee believes that performance-based equity awards tied to the Company’s stock price and relative performance versus peers, and cash compensation, with meaningful performance targets, such as those under our Annual Incentive Plan (as defined below), will further align our NEOs’ interests with those of our stockholders, will motivate our NEOs to contribute to the Company’s growth and profitability and will link a larger portion of our NEOs’ compensation to the performance of the Company.

• Maximize Stockholder Value – Our annual incentive awards are subject to maximum payout caps that limit the amount an NEO may earn on any individual metric or operational measures.

• Create Ownership Culture – Performance-based and time-based restricted stock unit awards, in each case, vesting over time, as well as robust stock ownership guidelines for our NEOs and non-employee directors, promote stock ownership culture and ensure that our NEOs and directors have a continuing stake in the long-term success of the Company. We believe that our long-term equity awards granted to our NEOs discourage excessive risk taking, as there is a balance between performance-based and time-based awards that moderates the risk that may otherwise exist if equity awards were to vest solely based upon achieving performance targets.

Based on the foregoing, the Compensation Committee believes that the Company utilizes compensation policies and programs so that there are no risks that are reasonably likely to have a material adverse impact on the Company.

Under the Sarbanes-Oxley Act of 2002, incentive compensation received by our Chief Executive Officer and Chief Financial Officer may be subject to clawback in the event of a restatement of our financial statements. On July 31, 2023, the Board approved a written executive compensation clawback policy. The Board has adopted a compensation recovery policy, also known as a “clawback,” pursuant to which the Company may seek to recover from any current or former executive officer all cash and equity incentive-based compensation in the event of an accounting restatement resulting from the Company’s material non-compliance with financial reporting requirements under applicable securities laws. The amount of incentive-based compensation subject to recovery would be the amount in excess of what the executive officer received over the amount the executive would have earned in accordance with the restatement as determined by the Compensation

38 2025 PROXY STATEMENT |  |

|  | EXECUTIVE SUMMARY

Committee. The compensation recovery policy also contains provisions related to the forfeiture of stock options, restricted shares, RSUs and PSUs. Under these forfeiture provisions, the company may cancel such long-term incentive awards, in whole or in part, whether or not vested, for no consideration, for executives who engage in serious breaches of conduct, including violations of employment agreements, confidential or other proprietary matters, or otherwise act in competition with the Business of the company. We believe these provisions serve to ensure that executives act in the best interest of the Company and its shareholders.

In addition, each award granted pursuant to the 2021 Incentive Plan (including awards granted to our NEOs) is conditioned on repayment or forfeiture in accordance with applicable laws, our Company policies and any relevant provisions in the related award agreements. Further, under the terms of our NEOs employment agreements, any equity awards granted, any proceeds of any equity awards that previously have been sold, transferred or otherwise disposed of, and any annual incentive award will be subject to clawback by us, now or in the future, under the Dodd-Frank Act and the Sarbanes-Oxley Act, each as amended, and their rules, regulations and binding, published guidance.

Stock Ownership Guidelines for Executive Officers

We believe it is important for our executive officers to align their financial interests with those of our stockholders. Accordingly, effective April 27, 2022, our Board of Directors adopted a formal stock ownership policy that requires our CEO to achieve a stock ownership level equal to the value of common stock that is five times the value of his annual base salary within five years of the effective date of such stock ownership policy. The Compensation Committee also designated our other executive officers that are subject to Section 16 reporting obligations under the Exchange Act, to be subject to the stock ownership policy. On February 20, 2025, our Board of Directors amended the stock ownership guidelines to provide that once a participant has satisfied the stock ownership requirements subsequent declines in the stock price will not affect compliance if the participant retains the number of shares held when they achieved compliance. The stock ownership level for our other NEOs and applicable Section 16 officers is three times the value of their respective annual base salaries to be achieved within five years of the effective date of our stock ownership policy. Messrs. Craine and Sluiter have met the company’s share ownership guidelines. Messrs. Reinhart, Hodges and Rucker have not been in their position long enough to be required to meet the minimum stock ownership guidelines; however, all are on track to do so within the prescribed timeframe through expected grants.

Our non-employee directors are also subject to the stock ownership policy discussed above under “Stock Ownership Guidelines for Directors.”

Anti-Hedging, Pledging and Insider Trading Policies

We have a policy prohibiting directors, executive officers and certain other designated employees from speculative trading in our securities, including hedging transactions, short selling, and trading in put options, call options, swaps or collars, or holding our securities in margin accounts. We also have a policy prohibiting directors, executive officers and certain other designated employees from pledging Gulfport securities. To our knowledge, all individuals follow these policies.

We have an Insider Trading Policy governing the purchase, sale and other dispositions of our securities by directors, officers and employees that is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards. A copy of the policy was filed as Exhibit 19 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Termination and Change of Control Benefits

As noted above, certain of our NEOs are (or were formerly) party to an employment agreement with the Company which provides (or provided) for certain payments and benefits in the event of a termination of such NEO under specific circumstances. The NEOs’ employment agreements are designed to avoid distraction potentially detrimental to stockholder value upon a change in control and to enhance protection for the NEOs in connection with such events. These agreements (and the severance payments referenced below) are described in more detail under “NEO Employment Agreements and Termination and Change of Control Benefits.”

Perquisites and Other Personal Benefits

We provide certain of our NEOs with a limited number of perquisites or other personal benefits, primarily consisting of life insurance premiums, fitness reimbursement, and Company-sponsored sporting events tickets. The Company does not offer any excessive perquisites to executives that are not generally provided to other non-executives. We believe these limited benefits help provide a competitive compensation package. The value of these benefits is disclosed in the “Summary Compensation Table.”

|  | 2025 PROXY STATEMENT 39

EXECUTIVE SUMMARY |  |

The Company does not have any private or chartered aircraft arrangements. We restrict personal use of Company-owned or chartered aircraft by our executive officers and other employees, as well as members of our Board of Directors. Our aircraft use policy requires that any personal use of a chartered aircraft by any NEO be reported as a perquisite, based on the aggregate incremental value of such personal use. There was no business or personal use of Company-owned or chartered aircraft in 2024.

Accounting Implications of Executive Compensation Policy

We are required to recognize compensation expense of all stock-based awards pursuant to the provisions of FASB ASC Topic 718, “Compensation-Stock Compensation.” Under U.S. generally accepted accounting principles, or GAAP, only vested shares are included in basic shares outstanding. Also, under GAAP, non-vested shares are included in diluted shares outstanding when the effect is dilutive.

The Compensation Committee believes that linking a large portion of our executive officers’ compensation to both performance-based long-term equity incentive awards and performance-based bonus arrangements, with meaningful performance metrics, appropriately aligns our executives’ interests with those of our stockholders and are consistent with market practices. The Compensation Committee also believes that our current compensation policies and practices enhance retention of executive talent through multi-year vesting of stock awards and discourage unnecessary and excessive risk taking. The Compensation Committee further believes that our other compensation policies and practices, such as our policy prohibiting pledging and hedging of our stock by our executive officers and directors, as well as the lack of significant perquisites and absence of pension or supplemental retirement benefits (aside from those afforded under our broad-based 401(k) plan) for our executive officers are consistent with prudent compensation philosophy and the interests of our stockholders. The Compensation Committee will continue to consider the outcome of our stockholders’ future “Say-On-Pay” votes when making compensation decisions for our NEOs.

Benefit Plans

401(k) Plan

We maintain a retirement savings plan, the safe harbor 401(k) Plan, with both traditional and Roth options, for the benefit of our eligible employees who have attained the age of 18. Currently, employees may elect to defer their compensation up to the statutorily prescribed limit. During the plan year, we provide a Company match of 100% up to 6% of eligible compensation. We also may make an additional, discretionary contribution based on each eligible employee’s eligible annual compensation for the prior calendar year. All contributions made by us on behalf of an employee are 100% vested when contributed. Employee contributions to the traditional 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) Plan, while participants in our Roth 401(k) may make Roth deferrals which are generally subject to taxation under rules applicable to Roth accounts. All contributions are deductible by us when made.

2021 STOCK INCENTIVE PLAN

On May 17, 2021, our Board adopted the Gulfport Energy Corporation 2021 Stock Incentive Plan (the “2021 Incentive Plan”) and authorized and reserved 2,828,123 shares of Gulfport’s common stock for issuance to Gulfport’s employees (including our NEOs), consultants and non-employee directors pursuant to equity incentive awards to be granted under the 2021 Incentive Plan, which may be in the form of incentive stock options, nonqualified stock options, restricted stock, restricted stock units, stock appreciation rights and performance awards or any combination of the foregoing.

The plan administrator may at any time amend or terminate the Annual Incentive Plan in whole or in part.

Our Board of Directors has delegated its authority to administer the Annual Incentive Plan to the Compensation Committee, to whom we refer as the plan administrator. The plan administrator has the authority to administer the Annual Incentive Plan and to exercise all the powers and authorities either specifically granted to it under the Annual Incentive Plan or necessary or advisable in the administration of the Annual Incentive Plan, including (but not limited to) the following:

• to interpret the Annual Incentive Plan and any award;

• to prescribe rules relating to the Annual Incentive Plan;

• to determine the persons to receive awards;

• to determine the terms, conditions, restrictions and performance criteria, including performance factors and performance targets, relating to any award;

• to accelerate an award that is designed not to be deferred compensation subject to Code Section 409A (after the attainment of the applicable performance target or targets);

• to adjust performance targets in recognition of specified events such as unusual or non-recurring events affecting us or our financial statements, including certain asset dispositions, cessation of operations resulting from a natural disaster, or in response to changes in applicable laws, regulations, or accounting principles as specified in the Annual Incentive Plan or in the performance targets established for any performance period;

• to waive restrictive conditions for an award (but not performance targets); and

• to make any other determinations that may be necessary or advisable for administration of the Annual Incentive Plan.

Former Chief Executive Officer Offer Letter and Employment Agreement

On April 29, 2022, we entered into an employment agreement with Mr. Cutt to serve as our Chief Executive Officer and Executive Chair of the Board of Directors.

Pursuant to the employment agreement, the term of Mr. Cutt’s service as Chief Executive Officer shall continue until such time as either Mr. Cutt or the Company gives notice of intent to terminate. Mr. Cutt will continue to serve as Board Chair following the termination of his employment as Chief Executive Officer (subject to the Board’s ability to remove him at any time). The employment agreement also provides for, among other things, (i) an annual base salary of $785,000, (ii) eligibility to receive an annual bonus with a target bonus opportunity of 120% of base salary; (iii) eligibility for annual grants of equity awards as determined in the sole discretion of the Compensation Committee pursuant to the Company’s equity compensation plans; and (iv) benefits that are customarily provided to similarly situated executives of the Company.

Mr. Cutt’s employment agreement also contains a one-year post-employment non-solicitation clause and standard confidentiality, trade secrets and cooperation provisions.

On January 24, 2023, we entered into a Transition and Services Agreement (“TSA”) with Mr. Cutt where he transitioned employment from Chief Executive Officer to Executive Chair of the Board. The transition period was from January 24, 2023, through March 1, 2023 (“Service Period”), during which time Mr. Cutt was employed by the Company as Executive Chair of the Board.

Pursuant to the terms of the PSA, Mr. Cutt received the same base salary he had as Chief Executive Officer, his annual bonus for fiscal year 2022 and a pro-rated portion of his target annual bonus for fiscal year 2023.

The TSA clarifies that Mr. Cutt’s outstanding equity awards granted during his tenure as Chief Executive Officer shall continue to be eligible to vest following the end of his service as Chief Executive Officer or Executive Chair of the Board in accordance with the vesting provisions contained in the applicable RSU Award Agreements and the PSU Award Agreements as long as Mr. Cutt continues to provide services to the Company as a member of the Board.

NEO Employment Agreements and Termination and Change of Control Benefits

Our NEOs are parties to an employment agreement with the Company.

Pursuant to the employment agreements with Messrs. Reinhart, Hodges, Craine, Rucker, and Sluiter (collectively, the “Employment Agreements”, and such individuals, the “Covered NEOs”), each current employment agreement provides for an initial term that extends through December 31, 2026; provided that the term will automatically renew for successive one-year terms unless the Company or the Covered NEO gives written notice not to renew at least 90 days before the end of the initial term or any renewal

|  | 2025 PROXY STATEMENT 47

Benefit Plans |  |

term. If a “change of control” (as described in the applicable Employment Agreement) occurs during the term thereof, the term will be extended to the later of the original expiration date of the term or the date that is 24 months after the effective date of the change of control.

The Employment Agreements provide each Covered NEO with, among other things: (i) an annual base salary, (ii) eligibility to earn a target annual bonus under the Company’s Annual Incentive Plan of base salary, (iii) eligibility for annual grants of equity awards as determined in the sole discretion of the Compensation Committee pursuant to the Company’s equity compensation plans, and (iv) benefits that are customarily provided to similarly situated executives of the Company.

In addition, our Covered NEOs will be entitled to receive (or have already received) specified payments and benefits upon certain termination events pursuant to the Employment Agreements, including termination following a change of control. The Compensation Committee believes that these provisions encourage our Covered NEOs to remain in our employment, as applicable, in the event of a change of control of the Company and during circumstances which indicate that a change of control might occur. The Compensation Committee believes termination and change of control benefits are important in maintaining strong leadership and in encouraging retention in these situations and encourages our Covered NEOs to act in the best interests of stockholders without distraction based on uncertainty regarding their employment status, as applicable. Under the Employment Agreements, if a Covered NEO’s employment is terminated without “cause” by the Company or by the applicable Covered NEO for “good reason” during such time that is not within the 24-month period following a “change of control” (as such terms are defined in the Employment Agreements), such Covered NEO will be entitled to severance compensation equal to:

• 100% of annual base salary and target annual bonus;

• pro-rata target annual bonus;

• pro-rated vesting of the Covered NEO’s unvested equity awards (with performance award vesting based on performance through the termination date); however, see “RSU and PSU Grant Agreements” for terms applicable to equity awards; and

• a lump sum payment equal to the Covered NEO’s monthly COBRA premium for a 12-month period.

If, however, such Covered NEO’s employment is terminated without cause by the Company or by the Covered NEO for good reason, in each case, within 24 months following a change of control, such Covered NEO will instead be entitled to severance compensation equal to:

• 200% of sum of annual base salary plus target annual bonus (300% for Mr. Reinhart);

• pro-rated target annual bonus;

• immediate vesting of the Covered NEO’s unvested equity awards (with performance award vesting based on performance through the termination date); however, see “RSU and PSU Grant Agreements” for terms applicable to equity awards; and

• a lump sum payment equal to the Covered NEO’s monthly COBRA premium for an 18-month period.

Under the NEO Employment Agreements:

“Good reason” is generally defined as (i) the elimination of the Covered NEO’s position, a material reduction in the duties and/or reassignment of the Covered NEO to a new position of materially less authority; (ii) a material reduction in the Covered NEO’s base salary, in either case, subject to a cure period of 30 days; (iii) the relocation of the NEO’s principal place of employment by more than 50 miles.

“Cause” is generally defined as (i) the Covered NEO’s willful and continued failure to perform substantially such Covered NEO’s duties with the Company (other than any failure resulting from incapacity due to physical or mental illness) or (ii) the Covered NEO’s willful engaging in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company.

RSU and PSU Grant Agreements:

Messrs. Reinhart, Hodges, Craine, Rucker, and Sluiter each received an award of time-based restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”) under the 2021 Stock Incentive Plan on March 1, 2024.

Pursuant to the applicable award agreements, upon the applicable NEO’s termination of employment or service for cause, any unvested RSUs or PSUs will be immediately forfeited for no consideration.

Upon a termination of the applicable NEO’s employment or service due to death or “disability”, by the Company without “cause” (each as defined in the 2021 Incentive Plan) or due to a resignation by the applicable NEO for “good reason” (as defined in the applicable award agreement), (i) any unvested RSUs will accelerate and fully vest, and (ii) a prorated portion of the PSUs will vest based on the actual achievement of the performance conditions to be determined at the expiration of the performance period, and any remaining unvested PSUs will be forfeited (provided, that if the applicable NEO is terminated by the Company without cause or resigns for good reason within the first 18 months of the performance period, the Compensation Committee will have sole discretion whether the PSUs will accelerate and vest in such manner.

Upon the occurrence of a “change in control” (as defined in the 2021 Incentive Plan), to the extent the RSUs or PSUs, as applicable, are not assumed by the surviving entity, (i) any unvested RSUs will accelerate and fully vest, and (ii) the applicable NEO will become vested in 100% of the target award of PSUs or, if greater, the percentage of the target award of PSUs earned based on the actual achievement of the performance conditions to be determined as if the change in control was the last day of the performance period (except that the TSR for the Company and each of the peer companies will be determined using the closing price as of the closing date of the change in control compared to the reference value).

Upon the occurrence of a change in control, to the extent the RSUs or PSUs, as applicable, are assumed by the surviving entity, (i) upon the termination of the applicable NEO’s employment or service due to death or disability, by the Company without cause or by the applicable NEO for good reason within the 24 month period following such change in control, any unvested RSUs will accelerate and fully vest, and (ii) the PSUs will be converted, as of the date of such change in control, into time-based restricted stock units (the “Converted RSUs”), subject to the applicable NEO’s continuous employment or service through the date of such change in control, with the number of PSUs to be converted equal to 100% of the target award of PSUs or, if greater, the percentage of the target award of PSUs earned based on the actual achievement of the performance conditions to be determined as if the change in control was the last day of the performance period (except that the TSR for the Company and each of the peer companies will be determined using the closing price as of the closing date of the change in control compared to the reference value), and 100% of the Converted RSUs will vest, if at all, on the last day of the performance period, subject to the applicable NEO’s continuous employment or service through such date; provided, that if the applicable NEO’s employment or service is terminated due to death or disability, by the Company without cause or by the applicable for good reason following such change in control, 100% of the Converted RSUs will vest as of the date of such termination.

In the event of (i) a change in the composition of the Board such that, for a period of 30 days, the majority of the members of the Board are no longer considered “independent” (as described in the applicable award agreement) or (ii) any stockholder becomes the beneficial owner of more than 75% of the total combined voting power of all classes of stock of the Company (each such event, a “Special CiC Event”), (x) any unvested RSUs will accelerate and fully vest, and (y) the applicable NEO will become vested in 100% of the target award of PSUs or, if greater the percentage of the target award of PSUs earned based on the actual achievement of the performance conditions to be determined as of the Special CiC Event (determined as if the Special CiC Event was the last day of the performance period).

CEO Pay Ratio Disclosure

Pursuant to Item 402(u) of Regulation S-K, we are disclosing the pay ratio and supporting information comparing the median of the annual total compensation of our employees (including full-time, part-time, seasonal and temporary employees) other than Mr. Reinhart, our President and Chief Executive Officer and Board Director, as of December 31, 2023 (the date selected to identify the ‘median employee’, as further described below), and the annual total annualized compensation of Mr. Reinhart. The pay ratio is calculated in a manner consistent with Item 402(u) of Regulation S-K.

For the year ended December 31, 2024, our last completed fiscal year:

• The annual total compensation of our median employee was approximately $124,161.

• The total annualized compensation of Mr. Reinhart was approximately $8,988,358.

Based on this information, for 2024 the ratio of the annual total compensation of Mr. Reinhart to the median of the annual total compensation of all other employees was approximately 72:1.

We selected December 31, 2024, as the date upon which we identified the median employee. We reviewed the Medicare Taxable Earnings as reported on IRS Form W-2 (Box 5) for 2024 for all individuals employed by us on December 31, 2024 (other than Mr. Reinhart) and identified the median employee based on Medicare Taxable Earnings.

Once we identified our median employee, we calculated that employee’s annual total compensation for 2024 in the same manner that we determined the total compensation of our NEOs for purposes of the Summary Compensation Table set forth above. This resulted in an annual total compensation of $124,161 for the identified employee for the year ended December 31, 2024. The total compensation for Mr. Reinhart was calculated based on the values included in the Summary Compensation Table set forth above, which totaled $8,988,358. Mr. Reinhart participates in the Company’s benefit plans, including the 401(k) plan, has imputed income on Company-paid life insurance provided to all employees, imputed income on company paid executive long-term disability insurance, $1,144.95 for spousal travel to attend a business-related trip, income for non-cash fringe benefits for Company-sponsored sporting event tickets, and receives a monthly gym reimbursement benefit available to all employees. We made no material assumptions, adjustments, or estimates to identify the median employee or to determine total compensation, and we did not annualize the compensation for any employees that were not employed by us the entire year.

We believe that the pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. In addition, because the Securities and Exchange Commission rules for identifying the median employee allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to our pay ratio, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Pay Versus Performance

As previously discussed in the CD&A above, our Compensation Committee has focused on implementing executive compensation plans with the goal of tying our NEOs’ realized compensation to the achievement of Gulfport’s financial, operational, and strategic objectives, and aligning executive pay with changes in the value of our shareholders’ returns. The following table sets forth additional compensation information for our NEOs, calculated in accordance with SEC regulations, for fiscal years 2024, 2023, 2022, 2021 and 2020.

Adjusted Free Cash Flow was calculated assuming realized commodity pricing received throughout the year was consistent with the forward curve pricing used to set the approved Adjusted Free Cash Flow Metric in February of 2024.

(5) The non-PEO NEOs during 2023 and 2024 were Messrs Hodges, Craine, Rucker, and Sluiter.

The Company believes that the three key financial performance measures most relevant to linking pay and performance over the long term are, in no particular order, Adjusted Free Cash Flow, Net Income and TSR. The following three tables describe the link between those metrics and “compensation actually paid” (CAP) to our CEO and other NEOs in 2024 to Company performance.

Equity Compensation

In 2024, all current non-employee directors received grants of restricted stock units valued at $150,000 with a 1-year cliff vest on May 26, 2024.

Stock Ownership Guidelines for Directors

We believe it is important for members of our Board of Directors to align their financial interests with those of our stockholders. Accordingly, effective April 27, 2022, our Board of Directors adopted a formal stock ownership policy that requires our non-employee directors to achieve a stock ownership level equal to the value of common stock that is five times the value of their annual retainer within five years of the effective date of such stock ownership policy. On February 20, 2025, our Board of Directors amended the stock ownership guidelines to provide that once a participant has satisfied the stock ownership requirements subsequent declines in the stock price will not affect compliance if the participant retains the number of shares held when they achieved compliance. Messrs. Cutt, Wolf, Martinez, and Reganato have met their required stock ownership levels, and Ms. Powers, Mr. Reinhart, and Ms. Shafer-Malicki are all on track to meet their required stock ownership levels within the 5-year requirement.

2024 Director Compensation Table

The following table contains information with respect to 2024 compensation of our non-employee directors who served in such capacity during 2024.

Certain Relationships and Review and Approval of Related Party Transactions

The Audit Committee, as provided in its charter, reviews and approves related party transactions. The Company does not have a formal set of standards to be substantively applied to each transaction reviewed by the Audit Committee. Instead of a formalized policy, related party transactions are reviewed and judgment is applied to determine whether transactions are in the best interests of the Company. Further, the Company’s Code of Business Conduct and Ethics governs various compliance areas, including conflicts of interest and fair dealings, which are considered in the process of the review and approval of related party transactions.

The Company’s policy is that all its employees and directors, as well as their family members, must avoid any activity that is or has the appearance of conflicting with the Company’s business interest. This policy is included in the Company’s Code of Business Conduct and Ethics posted on its website. Each director and executive officer is instructed to always inform the designated compliance officer when confronted with any situation that may be perceived as a conflict of interest. Only the Board of Directors or a committee consisting solely of independent directors may grant waivers of the provisions of the Code of Business Conduct and Ethics for the Company’s executive officers and directors. In addition, at least annually, each director and executive officer completes a detailed questionnaire specifying any business relationship that may give rise to a conflict of interest.

Further, under the Audit Committee charter, the Audit Committee is responsible for reviewing and monitoring compliance with our Code of Business Conduct and Ethics and recommending any warranted changes to the Board of Directors. In addition, the Board of Directors and, pursuant to its written charter, the Audit Committee, reviews and approves all relationships and transactions in which the Company and its directors, director nominees and executive officers and their immediate family members, as well as holders of more than 5% of any class of our voting securities and their family members, have a direct or indirect material interest. The Board of Directors and the Audit Committee approve only those transactions that, considering known circumstances, are consistent, or are not inconsistent with, the Company’s best interests, as they determine in the good faith exercise of their discretion.

During 2024, Gulfport employed Sara Disser who is the daughter of the Company’s Chief Executive Officer. She received total compensation of $153,753.

As part of Gulfport’s existing $1.0 billion share repurchase program, Gulfport purchased $79,134,000 in common stock from affiliates of Silver Point Capital, L.P. in 2024.

Proposal to Ratify the Appointment of Our Independent Auditors (Proposal 2)

The Company is asking its stockholders to vote to ratify the appointment of Grant Thornton LLP as our independent auditors for fiscal year ending December 31, 2025. The Audit Committee has appointed Grant Thornton LLP to serve as independent auditors.

What services do the independent auditors provide?

Audit services of Grant Thornton LLP for fiscal year 2024 included an audit of our consolidated financial statements and services related to periodic filings made with the SEC. Additionally, Grant Thornton LLP provided certain services related to the consolidated quarterly reports as described below.

How much were the independent auditors paid in 2024 and 2023?

Grant Thornton LLP’s fees for professional services totaled $1,151,750 for 2024 and $1,154,865 for 2023. Grant Thornton LLP’s fees for professional services included the following:

• Audit Fees – aggregate fees for audit services, which relate to the fiscal year consolidated audit, quarterly reviews, accounting consultations and comfort letters were $1,151,750 for 2024 and $1,154,865 for 2023.

• Audit-Related Fees – aggregate fees for audit-related services, consisting of audits in connection with proposed or consummated dispositions, benefit plan audits, other subsidiary audits, special reports, and accounting consultations, were $0 in 2024 and 2023.

• Tax and All Other Fees – there were no tax or other fees for products or services provided by Grant Thornton LLP in addition to the services described above in 2024 and 2023.

Does the Audit Committee approve the services provided by Grant Thornton LLP?

It is our Audit Committee’s policy to pre-approve all audit, audit-related and permissible non-audit services rendered to us by our independent auditor. Consistent with such policy, all fees listed above that we incurred for services rendered by Grant Thornton LLP in fiscal years 2024 and 2023 were pre-approved by our Audit Committee. No non-audit services were provided to us by Grant Thornton LLP in 2024 or 2023.

Will a representative of Grant Thornton LLP be present at the meeting?

Yes, one or more representatives of Grant Thornton LLP will be present at the meeting. The representatives will have an opportunity to make a statement if they desire and will be available to respond to appropriate questions from the stockholders.

Has Grant Thornton LLP always served as Gulfport’s independent auditors?

Grant Thornton LLP has served as our independent auditors since 2005.

Vote Required and Board Recommendation

Stockholder ratification of the appointment of our independent auditors is not required by the Bylaws or otherwise. However, we are submitting this proposal to the stockholders as a matter of good corporate practice. Approval of this proposal requires the affirmative vote “for” the proposal of a majority of the votes cast by the stockholders present in person or represented by proxy at the Annual Meeting and entitled to vote thereon. The persons named as proxies for the Company intend to vote the proxies “FOR” Proposal 2. Abstentions and broker non-votes, if any, will have no effect on the voting results for Proposal 2.

If the appointment of Grant Thornton LLP is not ratified, the Audit Committee will reconsider the appointment. Even if the appointment is ratified, the Audit Committee in its discretion may direct the appointment of a different independent audit firm at any time during the year if it is determined that such change would be in best interests of the Company and its stockholders.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF GRANT THORNTON LLP AS THE COMPANY’S INDEPENDENT AUDITORS FOR THE YEAR 2025.

60 2025 PROXY STATEMENT |  |

Proposal to Approve, on an Advisory, NON-BINDING Basis, the Compensation Paid to the Company’s Named Executive Officers (Proposal 3)

Pursuant to Section 14A of the Exchange Act, the Company is asking its stockholders to vote to approve, on an advisory, non-binding basis, the compensation paid to the Company’s NEOs as reported in this proxy statement. This is also known as a “Say-On-Pay” vote. The Company’s stockholders are being asked to vote on the following resolution:

“RESOLVED, that the compensation paid to the Company’s NEOs, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby approved.”

This vote is advisory, which means that the vote on executive compensation is not binding on the Company, our Board of Directors or the Compensation Committee. While the vote on executive compensation is solely advisory in nature, our Board of Directors and the Compensation Committee will review and consider the “Say-On-Pay” voting results when making future decisions regarding our executive compensation program.

Stockholders are encouraged to carefully review the “Compensation Discussion and Analysis” section of this proxy statement, which discusses in detail the Company’s compensation policy and compensation arrangements which the Company believes are appropriate and reasonably consistent with market practice and with the long-term interests of the Company and its stockholders. In furtherance of the Company’s goals and objectives, the Compensation Committee, among other things, emphasizes long-term equity awards and annual performance bonuses under the previously implemented Annual Incentive Plan to align our executives’ interests more closely with those of our stockholders and to link a larger portion of our executives’ compensation to the performance of our stock and our operational performance.

We have determined that our stockholders should cast an advisory vote on the compensation of our NEOs on an annual basis. Unless this policy changes, the next advisory vote on the compensation of our NEOs will be at the 2026 Annual Meeting.

Vote Required and Board Voting Recommendation

Proposal 3 requires an affirmative vote “for” the proposal by a majority of the votes cast by the stockholders present in person or represented by proxy at the Annual Meeting and entitled to vote thereon. The persons named as proxies for the Company intend to vote the proxies “FOR” Proposal 3. Abstentions and broker non-votes, if any, will have no effect on the voting results for Proposal 3.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THIS PROPOSAL 3.

PROPOSAL TO AMEND OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO PROVIDE FOR OFFICER EXCULPATION (Proposal 4)

The Board is asking stockholders to consider and vote upon a proposal to approve an amendment (the “Exculpation Amendment”) to the Amended and Restated Certificate of Incorporation of Gulfport Energy Corporation to reflect current Delaware corporate law provisions permitting the exculpation of certain officers. The Board approved, subject to stockholder approval, and declared advisable to recommend the stockholders approve the Exculpation Amendment.

The Company’s current Amended and Restated Certificate of Incorporation provides for the exculpation of directors but does not include a provision that allows for the exculpation of officers. Effective August 1, 2022, Section 102(b)(7) of the General Corporation Law of the State of Delaware (“DGCL”) was amended to enable a Delaware corporation to limit the liability of certain of its officers in limited circumstances. Section 102(b)(7) of the DGCL, as amended, only permits, and the Exculpation Amendment would only permit, the exculpation of certain officers in connection with direct claims brought by stockholders, including class actions, but would not eliminate officers’ monetary liability for breach of fiduciary duty claims brought by the Company itself or for derivative claims brought by stockholders in the name of the Company. In addition, as is currently the case with directors under the current Amended and Restated Certificate of Incorporation, the Exculpation Amendment would not limit the liability of officers for any breach of the duty of loyalty to the Company or its stockholders, any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law and any transaction from which the officer derived an improper personal benefit.

This Proposal 4 requests that stockholders approve the Exculpation Amendment to extend the exculpation provision to certain of our officers as permitted by DGCL Section 102(b)(7), as amended, by adding a new paragraph to Article VII of the Amended and Restated Certificate of Incorporation as follows:

“The personal liability of the officers of the Corporation is hereby eliminated to the fullest extent permitted by the DGCL (including, without limitation, paragraph (7) of subsection (b) of Section 102 thereof), as the same may be amended and supplemented from time to time. If the DGCL hereafter is amended to authorize the further elimination or limitation of the liability of officers, then the liability of an officer of the Corporation, in addition to the limitation on personal liability provided herein, shall be limited to the fullest extent permitted by the amended DGCL. Any repeal or modification of this paragraph by the stockholders of the Corporation shall be prospective only, and shall not adversely affect any limitation on the personal liability of an officer of the Corporation existing at the time of such repeal or modification.”

The Board recognizes that the change to DGCL Section 102(b)(7) was intended to remedy potential inconsistent treatment between directors and officers and to address rising insurance costs and litigation costs for stockholders. The Board believes it is necessary to fully extend this exculpation protection to officers permitted by the DGCL and, that by including the officer exculpation provision as set forth above, the Company will be better able to attract and retain experienced and qualified corporate officers. The Board believes that in the absence of such protection, qualified officers might be deterred from serving as officers of the Company due to exposure to personal liability and the risk that substantial expense may be incurred in defending lawsuits, regardless of merit. Given such risks, the Board believes that the Exculpation Amendment will enable the covered officers to continue exercising their business judgment on the Company’s behalf without risking personal liability for unintentional outcomes. Further, the Board believes that this proposal would not have a negative impact on stockholder rights, particularly considering the narrow class and type of claims for which officers’ liability would be exculpated, thereby providing a reasonable and appropriate balance between stockholder and Company interests. Accordingly, the Board unanimously recommends that stockholders vote “FOR” this proposal.

Vote Required and Board Voting Recommendation

Proposal 4 requires an affirmative vote “for” the proposal by a majority of the outstanding shares of common stock and preferred stock voting on an as converted basis as a single class. The persons named as proxies for the Company intend to vote the proxies “FOR” Proposal 4. Abstentions and broker non-votes will have the effect of votes against this matter.

If Proposal 4 is approved, the Company intends to file the Exculpation Amendment, in the form attached to this Proxy Statement as Annex A, with the Secretary of State of the State of Delaware as soon as practicable following stockholder approval. The Exculpation Amendment will become effective at the time of that filing.

Attached to this Proxy Statement as Annex B is a copy of the current Article VII of the Amended and Restated Certificate of Incorporation reflecting the proposed additions to such language.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THIS PROPOSAL 4.

Audit Committee Report

The primary role of the Audit Committee is to assist the Board of Directors in its oversight of the Company’s accounting and financial reporting processes. In doing so, the Audit Committee is responsible for the appointment and compensation of the Company’s independent registered public accounting firm and has oversight for its qualification, independence and performance. The Audit Committee charter guides our duties and responsibilities. The Audit Committee charter, which was last amended during 2021, is available on the Company’s website at https://www.gulfportenergy.com/investors/corporate-governance/governance-documents. As set forth in the charter, management is responsible for the internal controls and accounting and financial reporting processes of Gulfport Energy Corporation. The independent registered public accounting firm is responsible for expressing opinions on the conformity of Gulfport Energy Corporation’s audited consolidated financial statements with generally accepted accounting principles and on the effectiveness of the Company’s internal control over financial reporting. Our responsibilities include monitoring and overseeing these processes.

Our Committee is comprised of four non-employee, independent members of the Board of Directors. No member serves on more than two other public company audit committees. The Board of Directors has determined that all of the members of the Audit Committee are financially literate, and that David Wolf, Jason Martinez, Jeannie Powers, and David Reganato are financial experts as that term is defined by the SEC. The members of our Committee are not professionally engaged in the practice of accounting or auditing. The Audit Committee’s considerations and discussions referred to below do not assure that the audit of the Company’s financial statements has been carried out in accordance with generally accepted auditing standards, that the financial statements are presented in accordance with generally accepted accounting principles or that the Company’s auditors are in fact “independent”.

In the performance of our oversight function, we have reviewed and discussed the audited financial statements of the Company for the fiscal year ended December 31, 2024, and management’s assessment of the effectiveness of the Company’s internal control over financial reporting with the management of Gulfport Energy Corporation. We have met with Grant Thornton LLP, the Company’s independent registered public accounting firm, with and without management present. We discussed with Grant Thornton LLP the matters required to be discussed under the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC and such other matters as we have deemed to be appropriate, including the overall scope and plans for the audit. We also have received the written disclosures and the letter from Grant Thornton LLP required by the applicable PCAOB requirements regarding the independent accountant’s communications with the Audit Committee concerning independence, and we have discussed with Grant Thornton LLP that firm’s independence from management and the Company. We also reviewed the amount of fees paid to Grant Thornton LLP for both audit and non-audit services. In doing so, we considered whether the provision of non-audit services to the Company was compatible with maintaining the independence of Grant Thornton LLP.

Based on the reports and discussions above, we recommended to the Board of Directors that the audited financial statements be included in the Gulfport Energy Corporation 2024 Annual Report on Form 10K.

This report is not soliciting material, is not deemed to be filed with the SEC, and is not to be incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended, whether made before or after this date and irrespective of any general incorporation language in any filing.

This report has been furnished by the Audit Committee of the Board of Directors.

ABOUT THE ANNUAL MEETING

Why am I receiving these materials?

The Board of Directors has sent you this proxy statement and the accompanying proxy card to ask for your vote, as a stockholder of the Company, on certain matters that will be voted on at the Annual Meeting.

Who is soliciting my vote?

The Board of Directors is soliciting your vote at the Annual Meeting. The proposals to be voted on by the Company’s stockholders at the Annual Meeting are described below.

What am I voting on?

You are voting on:

• The election of seven directors to serve until the 2026 Annual Meeting (see Proposal 1 beginning on page 8 of this proxy statement).

• The ratification of Grant Thornton LLP as our independent auditors for the year ended December 31, 2025 (see Proposal 2 beginning on page 60 of this proxy statement).

• The approval, on an advisory, non-binding basis, of the compensation paid to the Company’s NEOs as described in this proxy statement (see Proposal 3 beginning on page 61 of this proxy statement).

• The approval of an amendment to the Company’s Amended and Restated Certificate of Incorporation to provide for exculpation of certain officers of the Company as permitted by amendments to Delaware law (see Proposal 4 beginning on page 62 of this proxy statement).

• Any other business properly coming before the meeting.

How does the Board of Directors recommend that I vote my shares?

Unless you give other instructions on your proxy card, the persons named as proxy holders on the proxy card will vote in accordance with the recommendations of our Board of Directors. The Board of Directors’ recommendations can be found with the description of each proposal in this proxy statement. In summary, the Board of Directors recommends a vote:

• “FOR” each of our director nominees.

• “FOR” the proposal to ratify Grant Thornton LLP as the Company’s independent auditors for the fiscal year ended December 31, 2025.

• “FOR” the proposal to approve, on an advisory, non-binding basis, the compensation paid to the Company’s NEOs as described in this proxy statement.

• “FOR” the proposal to amend the Company’s Amended and Restated Certificate of Incorporation to provide for officer exculpation.

What is a proxy?

A proxy is your legal designation of another person to vote the shares of common stock that you own. That other person is also referred to as a “proxy.” If you designate someone as your proxy in a written document, that document is called a proxy or a proxy card. We have designated Timothy Cutt, our Board Chair, and Patrick Craine, our Chief Legal and Administrative Officer and Corporate Secretary, as the Company’s proxies for the Annual Meeting.

Who is entitled to vote?

You may vote if you were the record owner of our common shares or preferred shares as of the close of business on the record date, which is March 28, 2025. Gulfport had [17,883,113] common shares outstanding as of the record date. Each share of common stock is entitled to one vote. In addition, Gulfport had [34,487] preferred shares outstanding as of the record date. The

64 2025 PROXY STATEMENT |  |

|  | about the annual meeting

holders of Gulfport’s preferred stock are entitled to vote on all matters submitted to the stockholders for a vote, voting together with the holders of the common stock as a single class, on an as-converted basis. Gulfport’s [34,487] preferred shares outstanding as of the record date, on an as-converted basis, totaled approximately [2,463,357] common shares entitled to vote.

In aggregate, as of March 28, 2025, we had [408,069] shares of restricted stock units and performance-based restricted stock units awarded under our 2021 Stock Incentive Plan, but not yet vested. There is no cumulative voting.

How many votes must be present to hold the Annual Meeting?

Your shares are counted as present at the Annual Meeting if you attend the meeting and vote in person or if you return a properly executed proxy by mail. For us to hold our meeting, holders of a majority of the voting power of our outstanding shares of common stock and preferred stock as of the close of business on March 28, 2025, must be present in person or by proxy at the Annual Meeting. This is referred to as a “quorum.” Votes withheld and abstentions will be counted for purposes of establishing a quorum at the Annual Meeting. Broker non-votes, if any, will not be counted for purposes of establishing a quorum at the Annual meeting (see “What is the effect of abstentions, withhold votes and broker non-votes?” below)

What vote is required to elect directors (Proposal 1)?

The election of directors at the Annual Meeting will be conducted under a majority of the votes cast standard. This means that with respect to each director nominee, the number of votes cast “for” the director nominee must exceed the number of votes cast “against” the nominee. Abstentions will have no effect on the outcome of the election.

What vote is required to approve, on an advisory, non-binding basis, the ratification of the appointment of the Company’s independent auditor (Proposal 2)?

The proposal to approve, on an advisory, non-binding basis, the appointment of Grant Thornton LLP as Gulfport’s independent auditor for the year ending December 31, 2025, will be adopted if a majority of the votes present in person or by proxy and voting on this matter are cast “for” the proposal. You may vote “for,” “against” or “abstain” from approving the proposal. Abstentions will have no effect on the outcome of the proposal.

What vote is required to approve, on an advisory, non-binding basis, the compensation of the Company’s Named Executive Officers (Proposal 3)?

The proposal to approve, on an advisory, non-binding basis, the compensation of the Company’s NEOs will be adopted if a majority of the votes present in person or by proxy and voting on this matter are cast “for” the proposal. You may vote “for,” “against” or “abstain” from approving the proposal. Abstentions will have no effect on the outcome of the proposal.

What vote is required to approve an amendment to the Company’s Amended and Restated Certificate of Incorporation to provide for exculpation of certain officers of the Company as permitted by amendments to Delaware law (Proposal 4)?

The proposal to approve an amendment to the Company’s Amended and Restated Certificate of Incorporation to provide for exculpation of certain officers of the Company as permitted by amendments to Delaware law will be adopted if a majority of the outstanding shares of common stock and preferred stock voting on an as-converted basis as a single class present in person or by proxy and voting on this matter are cast “for” the proposal. You may vote “for,” “against” or “abstain” from approving the proposal. Abstentions and broker non-votes will have the effect of votes against this matter.

What is the effect of abstentions, withhold votes and broker non-votes?

If you specify that you wish to “abstain” or “withhold” from voting on an item, then your shares will not be voted on that item.

Because the votes cast in favor of each director nominee must exceed the votes cast against such nominee under Proposal 1 and because the votes cast in favor of the action must exceed the votes cast opposing the action in order to approve Proposals 2, 3 and 4 at the Annual Meeting. Abstentions will not have an effect on the outcome of Proposals 2 and 3 and will have the effect of votes against the matter on Proposal 4.

A “broker non-vote” occurs when a beneficial holder does not provide instructions to a broker and such broker lacks discretionary voting power to vote shares with respect to a particular proposal. Under NYSE rules, brokers are permitted to exercise discretionary voting authority on “routine” matters, but beneficial owners of shares must provide voting instructions to their brokers with respect to “non-routine” matters for their brokers to exercise voting authority with respect to such shares on such

|  | 2025 PROXY STATEMENT 65

about the annual meeting |  |

matters. Under NYSE rules, the proposal to approve the appointment of an independent auditor is considered a “routine” matter. This means that brokers may vote in their discretion on Proposal 2 on behalf of clients who have not furnished voting instructions with respect to such proposal. In contrast, Proposals 1, 3 and 4 are “non-routine” matters. This means brokers that have not received voting instructions from their clients on these proposals may not vote on these proposals in their own discretion, which results in “broker non-votes.”

Who is a registered stockholder and who is a beneficial stockholder?

Registered Stockholders: A “registered stockholder” is a person or entity whose name appears in the Company’s registered list of stockholders as an owner of one or more shares of the Company’s common stock or preferred stock. If you are a registered stockholder, these proxy materials are being sent directly to you.

Beneficial Stockholders: A “beneficial stockholder” or “beneficial owner” is a person or entity whose shares of the Company’s common stock or preferred stock are held by a bank, broker or other nominee (a.k.a. in “street name”). Most holders of our common stock hold their shares beneficially through a bank, broker or other nominee rather than of record directly in their own name. If you are a beneficial stockholder, these proxy materials are being forwarded to you by your bank, broker or other nominee, who is considered the registered stockholder of those shares. As the beneficial stockholder, you have the right to direct your bank, broker or other nominee on how to vote your shares and you are also invited to attend the Annual Meeting. Your bank, broker or other nominee has provided a voting instruction form for you to use in directing your bank, broker or other nominee as to how to vote your shares. You must follow these instructions for your shares to be voted. Your nominee is required to vote those shares in accordance with your instructions. If you do not give instructions to your broker, your broker will be able to vote your shares at its discretion with regard to Proposal 2, but will not be able to vote your shares at its discretion with respect to Proposals 1, 3 and 4.

How do I vote?

Registered Stockholders: If you are a “registered stockholder,” you can vote your shares in the following four ways:

• By Internet: You may vote by submitting a proxy over the Internet. Go to the website listed on your proxy card or voting instruction form and follow the instructions. You should have your proxy card, including your control number, in hand when you access the website.

• By Telephone: Stockholders located in the United States who receive proxy materials by mail may vote by submitting a proxy by telephone by calling the toll-free telephone number on the proxy card or voting instruction form and following the instructions.

• By Mail: If you received proxy materials by mail, you may vote by submitting a proxy by mail by completing, signing and dating the proxy card and mailing it in the enclosed, postage pre-paid envelope.

• In Person: You may attend in person and vote at the Annual Meeting.

Beneficial Stockholders: If you are a “beneficial stockholder,” then you will receive instructions from your bank, broker or other nominee on how to vote your shares. If you are a “beneficial stockholder,” you will need proof of ownership to be admitted to the Annual Meeting.

Can I change my vote?

You may change your vote by revoking your proxy at any time before it is exercised, which can be done by voting during the meeting, by delivering a new proxy or by notifying the inspector of election in writing. If your shares are held for you in a brokerage, bank or other institutional account, you must contact that institution to revoke a previously authorized proxy. The address for the inspector of election is Computershare Investor Services, 150 Royall Street, Suite 101, Canton, MA 02021.

Who counts the votes?

We have hired Computershare Investor Services, our transfer agent, to act as the tabulation agent and count the votes represented by proxies cast by mail or ballot. Employees of Computershare Investor Services will act as inspectors of election.

66 2025 PROXY STATEMENT |  |

|  | about the annual meeting

Could other matters be decided at the Annual Meeting?

We have not received any stockholder proposals and are not aware of any other matters that are expected to come before the Annual Meeting other than those described in this proxy statement. If any other matter should be presented at the Annual Meeting upon which a vote may be properly taken, shares represented by all proxy cards received by the Board will be voted at the discretion of the person or persons named as proxies on the enclosed proxy card.

How can I attend the Annual Meeting in person?

Registered stockholders will be asked to present a valid government-issued photo identification. If your shares are held in the name of your broker, bank or other nominee, you must bring to the meeting a valid government-issued photo identification and an account statement or letter (and a legal proxy if you wish to vote your shares) from the nominee indicating that you beneficially owned the shares on the record date for voting.

How can I access the Company’s proxy materials and annual report?

We have elected, in accordance with the Securities and Exchange Commission’s “Notice and Access” rule, to deliver a Notice of Internet Availability of Proxy Materials (the “Notice”) to our stockholders and to post our proxy statement and the Company’s 2024 Annual Report on Form 10-K (collectively, the “proxy materials”) electronically. The Notice is first being mailed to our stockholders on or about April 9, 2025. The proxy materials will first be made available to our stockholders on or about the same date. The Notice instructs you how to access and review the proxy materials and how to submit your proxy via the Internet. The Notice also instructs you how to request and receive a paper copy of the proxy materials, including a proxy card or voting instruction form, at no charge. We will not mail a paper copy of the proxy materials to you unless specifically requested to do so. Additionally, the Notice of the Annual Meeting, this proxy statement and the Company’s 2024 Annual Report on Form 10-K to Stockholders are available electronically on the Company’s website at www.gulfportenergy.com/proxy.

Where can I find the results of the Annual Meeting?

We intend to announce preliminary voting results at the Annual Meeting and intend to publish final results in a Current Report on Form 8-K, which we will file with the SEC within four business days after the Annual Meeting.

Availability of Form 10-K and Annual Report to Stockholders

SEC rules require us to provide an Annual Report to stockholders who receive this proxy statement. Additional copies of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, including the financial statements and the financial statement schedules, are available without charge to stockholders upon written request to Director of Investor Relations, Gulfport Energy Corporation, 713 Market Drive, Oklahoma City, Oklahoma 73114 or via the Internet at www.gulfportenergy.com. We will furnish the exhibits to our Annual Report on Form 10-K upon payment of our copying and mailing expenses.

HOUSEHOLDING

The SEC permits a single Notice or set of annual reports and proxy statements to be sent to any household at which two or more stockholders reside if they appear to be members of the same family, unless instructions have been received to the contrary. Each stockholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information stockholders receive and reduces our mailing and printing expenses.

If you would like to receive your own Notice or set of the annual report and proxy statement this year or in future years, follow the instructions described below, and we will promptly deliver a separate copy to you.

The Board of Directors does not intend to present any other items of business other than those stated in the Notice of Annual Meeting.

Solicitation by THE Board OF DIRECTORS

Participants in the Solicitation

We are required by law to convene an annual meeting of our stockholders at which directors are elected. Because shares of our common stock are widely held, it would be impractical for our stockholders to meet physically in sufficient numbers to hold a meeting. Accordingly, the Company is soliciting proxies from our stockholders. Our directors, director nominees, officers and employees may solicit proxies in person, or via mail, telephone, facsimile or email. Those persons will receive no additional compensation for any solicitation activities.

Expenses of Solicitation

U.S. federal securities laws require us to send you this proxy statement and any amendments or supplements, and to specify the information required to be contained in it. The Company will bear the expenses of calling and holding the Annual Meeting and the solicitation of proxies. These expenses will include, among other things, the costs of preparing, assembling, printing and mailing the proxy materials to stockholders of record and beneficial owners, and reimbursement paid to brokerage firms, banks and other fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy materials to stockholders and obtaining beneficial owners’ voting instructions.

FORWARD-LOOKING STATEMENTS

This proxy statement contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995. All statements relating to events or results that may occur in the future, including, but not limited to, the Company’s future prospects and performance, costs of solicitation, record or meeting dates, compensation arrangements, plans or amendments, Company policies, documents or amendments as well as capital and corporate structure (including major stockholders, Board structure and Board composition), are forward-looking statements.

Forward-looking statements are statements other than statements of historical fact. They include statements regarding Gulfport’s current expectations, management’s outlook guidance or forecasts of future events, projected cash flow and liquidity, share repurchases, its ability to enhance cash flow and financial flexibility, future production and commodity mix, plans and objectives for future operations, the ability of our employees, portfolio strength and operational leadership to create long-term value, the rejection of certain midstream contracts and the assumptions on which such statements are based. Gulfport believes the expectations and forecasts reflected in the forward-looking statements are reasonable, Gulfport can give no assurance they will prove to have been correct. They can be affected by inaccurate or changed assumptions or by known or unknown risks and uncertainties. Important risks, assumptions and other important factors that could cause future results to differ materially from those expressed in the forward-looking statements are described under “Risk Factors” in Item 1A of Gulfport’s annual report on Form 10-K for the year ended December 31, 2024, and any updates to those factors set forth in Gulfport’s subsequent quarterly reports on Form 10-Q or current reports on Form 8-K (available at https://www.gulfportenergy.com/investors/sec-filings).

Investors should note that Gulfport announces financial information in SEC filings, press releases and public conference calls. Gulfport may use the Investors section of its website (www.gulfportenergy.com) to communicate with investors. It is possible that the financial and other information posted there could be deemed to be material information. The information on Gulfport’s website is not incorporated into or a part of this filing.

Unless required by law, the Company does not intend, and undertakes no obligation, to update or publicly release any revision to any such forward-looking statements, whether as a result of the receipt of new information, the occurrence of subsequent events, a change in circumstances or otherwise. Each forward-looking statement contained in this proxy statement is specifically qualified in its entirety by the aforementioned factors. Readers are advised to carefully read this proxy statement in conjunction with the important disclaimers set forth above prior to reaching any conclusions or making any investment decisions, and not to place undue reliance on these forward-looking statements, which apply only as of the date of this proxy statement.

Submission of Future Stockholder Proposals

Under Rule 14a-8 under the Exchange Act (“Rule 14a-8”), a stockholder who intends to present a proposal for business at the 2026 Annual Meeting and who wishes the proposal to be included in the proxy statement and form of proxy for that meeting must submit the proposal in writing to our Corporate Secretary no later than December 10, 2025. The proposal must comply with the requirements of Rule 14a-8 under the Exchange Act and our Bylaws to be eligible for inclusion in the Company’s proxy materials.

If a stockholder wishes to submit a proposal for business or nomination of directors at the 2026 Annual Meeting other than in reliance on Rule 14a-8, in order for such proposal to be considered timely pursuant to our Charter and Bylaws, the stockholder’s notice must be delivered to or mailed and received by the Corporate Secretary at the principal executive offices of the Company not less than 60 days nor more than 90 days prior to May 21, 2026 (i.e., the first anniversary of the 2025 Annual Meeting). Accordingly, the stockholder’s notice must be delivered to or mailed and received by the Corporate Secretary not later than March 22, 2026 and not earlier than February 20, 2026. However, in the event that the date of the 2026 Annual Meeting is advanced by more than 30 days, or delayed by more than 70 days, from May 21, 2026, notice by the stockholder to be timely must be received not earlier than 120 days prior to the 2026 Annual Meeting, and not later than the close of business on the later of the 90th day prior to the 2026 Annual Meeting or the close of business on the 10th day following the day on which public announcement of the date of the 2026 Annual Meeting was first made. At present, the Company has not announced a meeting date for the 2026 Annual Meeting. The Company expects to announce the date of the 2026 Annual Meeting and provide formal notice in 2026.

In addition to satisfying the requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide a notice to our Company that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 23, 2026.

You can obtain a copy of the Charter and Bylaws by writing to the Corporate Secretary at the address below, or from the SEC website at www.sec.gov (the Charter and Bylaws are filed as exhibits to our latest report on Form 10-K filed with the SEC on February 26, 2025).

All written proposals and inquiries for copies of the Charter and Bylaws should be directed to Patrick Craine, our Chief Legal and Administrative Officer and Corporate Secretary, at Gulfport Energy Corporation, 713 Market Drive, Oklahoma City, Oklahoma 73114.
