About the Annual Meeting

Who is soliciting my vote?

The board of directors of Gulfport Energy Corporation, which we refer to as Gulfport, the Company and we in this proxy statement, is soliciting your vote at the 2015 Annual Meeting of Stockholders. In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, and consistent with the advisory vote of the Company’s stockholders obtained in 2011, the Company’s board of directors is providing the Company’s stockholders with a non-binding advisory vote on, among other proposals, the Company’s executive compensation. This and other proposals to be voted on by the Company’s stockholders at the 2015 Annual Meeting of Stockholders are described in more detail below.

What am I voting on?

You are voting on:

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 item in this proxy statement. In summary, the board of directors recommends a vote:

Who is entitled to vote?

You may vote if you were the record owner of our common stock as of the close of business on the record date, which is April 22, 2015. Each share of common stock is entitled to one vote. As of April 22, 2015, we had 96,641,075 shares of common stock outstanding and entitled to vote, excluding 424,590 shares of our restricted common stock granted under our 2013 Restated Stock Incentive Plan or its predecessors, but not yet vested. There is no cumulative voting.

How many votes must be present to hold the meeting?

Your shares are counted as present at the Annual Meeting if you attend the meeting and vote in person or if you properly return a proxy by mail. In order for us to hold our meeting, holders of a majority of the voting power of our outstanding shares of common stock as of the close of business on April 22, 2015 must be present in person or by proxy at the meeting. This is referred to as a quorum. Abstentions and broker non-votes will be counted for purposes of establishing a quorum at the meeting.

Table of Contents

What is a broker non-vote?

If a broker does not have discretion to vote shares held in street name on a particular proposal and does not receive instructions from the beneficial owner on how to vote those shares, the broker may return the proxy card without voting on that proposal. This is known as a broker non-vote. No broker may vote your shares without your specific instructions on any of the proposals to be considered at the Annual Meeting other than the ratification of our independent auditors.

How many votes are needed to approve each of the proposals?

In April 2014, our board of directors amended our bylaws to provide for the election of directors in uncontested elections by a majority of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon. The number of shares voted “FOR” a director nominee must exceed the number of votes cast “AGAINST” that nominee. Abstentions and broker non-votes will not be counted for voting purposes with respect to the re-election of directors. Stockholders may not cumulate their votes with respect to the re-election of directors. If any incumbent director is not elected because he does not receive a majority of the votes cast, he is required to immediately tender his or her resignation for consideration by our board of directors. Our board of directors will evaluate whether to accept or reject such resignation, or whether other action should be taken; provided, however, that the board will act on such resignation and publicly disclose its decision to accept or reject such resignation and the rationale behind such decision within 90 days from the date of the certification of the director election results.

Each of Proposals 2 and 3 requires the affirmative “FOR” vote 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. Only votes for or against Proposal 2 will be counted as votes cast, and abstentions and broker non-votes will not be counted for voting purposes. Broker non-votes will be counted as votes cast with respect to Proposal 3.

How do I vote?

You can vote either in person at the meeting or by proxy without attending the meeting.

To vote by proxy, you must fill out the enclosed proxy card, date and sign it, and return it in the enclosed postage-paid envelope.

Even if you plan to attend the meeting, we encourage you to vote your shares by proxy. If you plan to vote in person at the Annual Meeting, and you hold your stock in street name, you must obtain a proxy from your broker and bring that proxy to the meeting.

Can I change my vote?

Yes. You can change or revoke your vote at any time before the polls close at the Annual Meeting. You can do this by:

Who counts the votes?

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

Table of Contents

Will my vote be confidential?

Yes. As a matter of Company policy, proxies, ballots and voting tabulations that identify individual stockholders are treated as confidential. Only the tabulation agent and the inspectors of election have access to your vote. Directors and employees of the Company may see your vote only if there is a contested proxy solicitation, as required by law or in certain other special circumstances.

Will my shares be voted if I don’t provide my proxy and don’t attend the Annual Meeting?

If you do not provide a proxy or vote your shares held in your name at the meeting, your shares will not be voted.

If you hold your shares in street name, your broker may be able to vote your shares for certain “routine” matters even if you do not provide the broker with voting instructions. The ratification of Grant Thornton LLP as our independent auditors for 2015 is considered routine. For matters not considered “routine,” if you do not give your broker instructions on how to vote your shares, the broker will return the proxy card without voting on that proposal. This is a broker non-vote. The proposals to elect directors and to approve, on an advisory basis, the Company’s executive compensation are not considered routine. As a result, no broker may vote your shares on these proposals without your specific instructions.

How are votes counted?

In the election of directors contemplated by Proposal 1, you may vote “FOR,” “AGAINST” or “ABSTAIN” with respect to one or more of the nominees. For Proposals 2 and 3, you may vote “FOR,” “AGAINST” or “ABSTAIN.”

What if I return my proxy but don’t indicate my vote on the matters listed on my proxy card?

If you return a signed proxy card without indicating your vote, your shares will be voted FOR the director nominees listed on the card, FOR approving, on an advisory basis, the Company’s executive compensation as described in this proxy statement and FOR the ratification of Grant Thornton LLP as our independent auditors for 2015.

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 will be considered at the Annual Meeting. If any other matters arise at the Annual Meeting, the persons named in your proxies will vote in accordance with their best judgment.

Who can attend the meeting?

The Annual Meeting is open to all holders of our common stock.

What do I need to bring to attend the Annual Meeting?

You will need proof of ownership of our common stock to enter the meeting. If your shares are in the name of your broker or bank or other nominee, you will need to bring evidence of your stock ownership, such as your most recent brokerage statement. All stockholders will be required to present valid picture identification. IF YOU DO NOT HAVE VALID PICTURE IDENTIFICATION AND PROOF THAT YOU OWN SHARES OF OUR COMMON STOCK, YOU MAY NOT BE ADMITTED INTO THE MEETING.

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

This proxy statement and the Company’s 2014 Annual Report to Stockholders are available on the Company’s website at www.gulfportenergy.com/proxy.

Board of Directors Information

What is the makeup of the board of directors and how often are the members elected?

Our board of directors currently consists of six members who are elected annually. The majority of these directors are independent under the Nasdaq listing standards.

What if a nominee is unable or unwilling to serve?

That is not expected to occur. If it does, shares represented by proxies will be voted for a substitute nominated by the board of directors.

How are directors compensated?

Our policy is that members of our board of directors who are also our officers or employees do not receive compensation for their services as directors. The compensation of our non-employee directors is described below.

Cash Compensation

Consistent with the recommendations of Longnecker & Associates, an independent compensation consulting firm, effective January 1, 2014, we paid our non-employee directors an annual retainer of $40,000, an attendance fee of $1,000 for each board meeting attended in person in 2014, increasing to $1,500 in 2015, and an attendance fee of $500 for each board meeting attended telephonically in 2014, increasing to $750 in 2015. In addition, effective January 1, 2014, the Chairman of the Board receives an additional $65,000 annual retainer, the audit committee chairman receives an additional $15,000 annual retainer and the chairman of each of the compensation committee and the nominating and corporate governance committee receives an additional $10,000 annual retainer. The annual retainer paid in 2014 to each committee member that was not the chairman of the respective committee was $3,000 per year, and effective January 1, 2014, each committee member was entitled to a $500 attendance fee for each committee meeting attended in person in 2014, increasing to $1,000 in 2015, and a $250 attendance fee for each committee meeting attended telephonically in 2014, increasing to $500 in 2015.

In March 2015, consistent with the recommendations of Longnecker & Associates in its December 2014 analysis of non-employee director compensation, the compensation committee recommended, and our board of directors approved, changes in compensation paid to non-employee directors of the Company for 2015. Effective January 1, 2015, our non-employee directors receive an annual retainer of $60,000, an attendance fee of $1,500 for each board meeting attended in person in 2015, and an attendance fee of $750 for each board meeting attended telephonically in 2015. The fees payable to our non-executive Chairman of the Board and the chairpersons of the audit, compensation and nominating and corporate governance committees remained at the 2014 levels discussed above. However, effective January 1, 2015, members of the audit, compensation and nominating and corporate governance committees of the board of directors who are not chairpersons of the respective committee no longer receive any additional retainers for such service. Each committee member will continue to receive attendance fees for each committee meeting, which, effective January 1, 2015, were set at $1,000 per each committee meeting attended in person and $500 for each committee meeting attended telephonically. The compensation committee also recommended, and the board of directors approved, an increase in the value of the annual grant of our restricted common stock to each non-employee director discussed in more detail under the heading “—Equity Compensation” below.

Equity Compensation

Effective January 1, 2014, our non-employee directors were entitled to receive an annual grant of restricted stock with an aggregate value of approximately $100,000 based on the closing price of our common stock on the date of grant, with vesting to occur in the following year. On July 10, 2014, we granted the 2014 annual director grant

in the amount of 1,609 shares of our restricted common stock to each of our then-serving non-employee directors under our 2013 Restated Stock Incentive Plan, which shares will vest on June 12, 2015 if the non-employee director is in continuous service on that date. Michael S. Reddin, one of our then-serving non-employee directors, resigned as a director of the Company effective August 4, 2014 and, in connection with such resignation, declined to accept the 1,609 shares of restricted stock granted to him on July 10, 2014 under the 2013 Restated Stock Incentive Plan. Further, in connection with the appointment of Ben T. Morris as a director of the Company effective August 4, 2014, Mr. Morris received grants under our 2013 Restated Stock Incentive Plan of (i) 374 shares of our restricted common stock as a signing bonus, which shares will vest on August 4, 2015, and (ii) 1,556 shares of our restricted common stock, which shares will vest on June 12, 2015 if he is in continuous service on that date, representing pro-rated equity compensation payable to our non-employee directors in 2014, based on Mr. Morris’ service on the board of directors commencing on August 4, 2014. Further information regarding our director compensation in 2014 is set forth under the heading “2014 Director Compensation” below.

As discussed above, effective January 1, 2015, the compensation committee also recommended, and the board of directors approved, a $25,000 increase in the value of the annual grant of our restricted common stock to each non-employee director (based on the market value of our common stock at the time of grant) to $125,000, with vesting to occur in the following year.

Insurance and Indemnification

We provide liability insurance for our directors and officers at a current annual cost of approximately $596,717. We have also entered into indemnification agreements with each of our current directors. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

In addition, our certificate of incorporation sets forth limitations on our directors’ liability to our stockholders. Further, our bylaws contain indemnification and advancement of expenses provisions for the benefit of our directors and officers.

How often did the board of directors meet in 2014?

The board of directors met 14 times in 2014. In addition to these meetings, the board of directors adopted resolutions by unanimous written consent. Each director attended at least 75% of the aggregate meetings of the board of directors and the meetings of the committees on which he served.

Do the committees have written charters?

Yes. The charters for our audit committee, compensation committee and nominating committee can be found on our website at www.gulfportenergy.com under the “Corporate Governance” caption. You may also obtain copies of these charters, as well as our Code of Business Conduct and Ethics, which is described below, by writing to our Assistant Corporate Secretary, Paul K.

Corporate Governance Matters and Communications with the Board

Who are our independent directors?

Our board of directors has determined that Donald L. Dillingham, Craig Groeschel, David L. Houston, Ben T. Morris and Scott E. Streller meet the standards regarding independence set forth in the Nasdaq listing standards and are free of any relationship which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out their responsibilities as directors of the Company.

Our board of directors has determined that each member of the audit committee is independent for purposes of serving on such committee under the Nasdaq listing standards and applicable federal law. In addition, our board of directors has determined that each current member of the audit committee is financially literate under the

9

Table of Contents

Nasdaq listing standards and that each of Mr. Houston, who serves as the Chairman of the audit committee, and Mr. Dillingham qualifies as the “audit committee financial expert,” as such term is defined in Item 407(d) of Regulation S-K.

Our board of directors has also determined that each member of the compensation committee and the nominating committee meets the independence requirements applicable to those committees under the Nasdaq rules. In addition, our board of directors determined that each member of our compensation committee is an “outside director” in accordance with Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code, and a “non-employee director” in accordance with Rule 16b-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act.

Do our non-management directors meet separately without management?

Our non-management directors have the opportunity to meet in an executive session following each regularly scheduled meeting of the board of directors. During 2014, our non-management directors met in an executive session on June 12, 2014.

How can I communicate with the board of directors?

Individuals may communicate with our board of directors or individual directors by writing to our Assistant Corporate Secretary, Paul K. Heerwagen IV, at Gulfport Energy Corporation, 14313 N. May Avenue, Suite 100, Oklahoma City, Oklahoma 73134. Our Assistant Corporate Secretary will review all such correspondence and forward to our board of directors a summary of all such correspondence and copies of all correspondence that, in the opinion of our Assistant Corporate Secretary, relates to the functions of our board of directors or a committee thereof or that he otherwise determines requires their attention. Directors may review a log of all such correspondence received by us and request copies. Concerns relating to accounting, internal control over financial reporting or auditing matters will be immediately brought to the attention of the chairman of the audit committee and handled in accordance with the audit committee procedures established with respect to such matters.

Do directors attend the Annual Meeting?

Recognizing that director attendance at our Annual Meeting can provide our stockholders with an opportunity to communicate with directors about issues affecting the Company, we actively encourage our directors to attend the Annual Meeting of Stockholders. All of our six directors then-serving attended the 2014 Annual Meeting of Stockholders in person.

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, including the Chief Executive Officer, the Chief Financial Officer and all senior financial officers. Our Code of Business Conduct and Ethics covers various topics including, but not limited to, conflicts of interest, fair dealing, discrimination and harassment, confidentiality, compliance procedures and employee complaint procedures. Our Code of Business Conduct and Ethics is posted on our website under the “Investor Relations—Corporate Governance” caption.

Nominating Process for Directors, Director Qualifications and Review of Director Nominees

The nominating committee is comprised of four non-employee directors, all of whom are independent under Nasdaq listing standards. As provided by the nominating committee’s charter, our nominating committee identifies, investigates and recommends to our board of directors candidates with the goal of creating a balance

10

Table of Contents

of knowledge, experience and diversity. Generally, the committee identifies candidates through the personal, business and organizational contacts of the directors and management and through the use of third-party search firms.

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 for director nominees are reviewed in the context of the current composition of our board of directors 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 meets the standards of independence promulgated by Nasdaq and the SEC and that all members reflect a range of talents, ages, 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. In addition to the foregoing factors, our nominating committee considers diversity in its evaluation of candidates for board membership. Although our board of directors does not have a formal diversity policy, our board believes that diversity with respect to viewpoint, skills and experience should be an important factor in board composition. Our nominating committee ensures that diversity considerations are discussed in connection with each potential nominee, as well as on a periodic basis in connection with its periodic review of the composition of the board and the size of the board as a whole.

We also require that the members of our board of directors be able to dedicate the time and resources sufficient to ensure the diligent performance of their duties on our behalf, including attending meetings of the board of directors and applicable committee meetings. In accordance with its charter, our nominating committee periodically reviews the criteria for the selection of directors to serve on our board and recommends any proposed changes to our board of directors for approval.

Our board of directors will consider stockholder nominations for director candidates upon written submission of such recommendation to our Corporate Secretary along with, among other things, the nominee’s qualifications and certain biographical information regarding the nominee, such nominee’s written consent to serving as a director if elected and being named in the proxy or information statement and certain information regarding the status of the stockholder submitting the recommendation, all in the manner required by our amended and restated bylaws and the applicable rules and regulations promulgated under the Exchange Act. Following verification of the stockholder status of persons proposing candidates, recommendations will be aggregated and considered by our board of directors at a regularly scheduled or special meeting. If any materials are provided by a stockholder in connection with the nomination of a director candidate, such 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 such nominations, our board of directors will seek to achieve a balance of knowledge, experience and capability on the board. 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 persons. After completing its evaluation, our board of directors approves the final slate of director nominees.

Our nominating committee approved the director nominees submitted for election at this Annual Meeting. Each nominee is a current board member and brings a strong and unique background and set of skills to our board of directors, giving our board of directors as a whole competence and experience in a variety of areas, including corporate governance and board service, executive management, oil and natural gas industry, accounting and finance and risk assessment and management. Specifically, in nominating the candidates submitted for election at this Annual Meeting, our nominating committee considered such candidates’ past service on our board and the information discussed in each of the directors’ individual biographies set forth beginning on page 5 above. In particular, with regard to Mr. Dillingham, our nominating committee considered his strong background in

finance and risk assessment and management developed as part of his career as a registered investment advisor and portfolio manager, as well as his academic experience. With regard to Mr. Groeschel, our nominating committee considered his leadership and prior board service at a non-profit organization, community involvement and administrative and public speaking skills. With regard to Messrs. Houston and Streller, our nominating committee considered their respective business backgrounds and risk assessment skills. Mr. Moore’s public company experience while serving in various executive officer capacities at Gulfport and leadership skills that led to his promotion as our Chief Executive Officer in April 2014, as well as his strong oil and natural gas background and extensive experience in finance, accounting, financial reporting, internal controls and corporate governance, led our nominating committee to appoint Mr. Moore as a director, effective April 22, 2014, and a nominee and to conclude that he should serve as one of our directors. Mr. Morris’ prior public company experience, extensive financial background, with over 20 years of experience in various aspects of the investment banking business, and strong oil and natural gas background led our nominating committee, following an extensive search process undertaken by Preng & Associates, an independent third-party search firm, in which approximately 80 potential candidates were reviewed, to appoint Mr. Morris as a director, effective August 4, 2014, and to recommend Mr. Morris as a nominee and to conclude that he should serve as one of our directors. Each of the director nominees has consented to serve as a director if elected.

Director Leadership Structure

Since December 2005, the positions of Chairman of the Board and Chief Executive Officer have been held by two different individuals. In July 2013, our board of directors amended our bylaws to make the Chairman of the Board a non-executive position to be elected from among the directors by the board, and named Mr. Houston as Chairman of the Board until his successor is duly appointed. On February 14, 2014, as previously announced, James D. Palm retired as our Chief Executive Officer and resigned from our board of directors. He was replaced as our Chief Executive Officer and as a member of our board of directors by Michael G. Moore. Separating the positions of Chairman of the Board and Chief Executive Officer has allowed our Chief Executive Officer to focus on our day-to-day business and operations, while allowing our Chairman of the Board to lead the board in its fundamental role of providing advice to and oversight of management. The Chairman of the Board has provided leadership to our board of directors and worked with the board of directors to define its structure and activities in the fulfillment of its responsibilities. The Chairman of the Board has set the board agendas, with the input from other members of the board and our management, facilitated communications among and information flow to directors, has the power to call special meetings of our board of directors and stockholders and presided at meetings of our board of directors and stockholders. The Chairman of the Board has also advised and counseled our Chief Executive Officer and other officers. Our board of directors does not have a position of a lead director.

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 six of our director nominees are independent under the Nasdaq listing standards and SEC rules. We believe that all of 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 and Compensation committees, each having an independent chairperson. Specifically, the chair of our audit committee oversees the accounting and financial reporting processes, as well as compliance with legal and regulatory requirements. The chair of our compensation committee oversees our compensation policies and practices and their impact on risk and risk management. The chair of our nominating committee monitors matters such as the composition of the board and its committees, board performance and best practices in corporate governance. As such, each committee chair provides independent leadership for purposes of many important functions delegated by our board of directors to such committee.

Board of Director’s Role in Risk Oversight

As an exploration and production company, we face a number of risks, including risks associated with the supply of and demand for oil and natural gas, volatility of oil and natural gas prices, exploring for, developing, producing and delivering oil and natural gas, declining production, environmental and other government regulations and taxes, weather conditions, including hurricanes, that can affect oil and natural gas operations over a wide area, adequacy of our insurance coverage, political instability or armed conflict in oil and natural gas producing regions and overall economic environment. Management is responsible for the day-to-day management of risks we face as a company, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

Our board of directors believes that full and open communication between management and the board of directors is essential for effective risk management and oversight. Our Chairman of the Board meets regularly with our Chief Executive Officer to discuss strategy and risks facing the Company. Our executive officers regularly attend the board meetings and are available to address any questions or concerns raised by the board on risk management-related and any other matters. Other members of our management team periodically attend board meetings or are otherwise available to confer with the board to the extent their expertise is required to address risk management matters. Periodically, our board of directors receives presentations from senior management on strategic matters involving our operations. During such meetings, our board of directors also discusses strategies, key challenges, and risks and opportunities for the Company with senior management.

While our board of directors is ultimately responsible for risk oversight at the Company, our three committees assist the board in fulfilling its oversight responsibilities in certain areas of risk. Our audit committee assists the board in fulfilling its oversight responsibilities with respect to risk management in the areas of financial reporting, internal controls and compliance with legal and regulatory requirements, and discusses policies with respect to risk assessment and risk management. Our compensation committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs. Our nominating committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks associated with board organization, membership and structure, succession planning for our directors and executive officers and corporate governance.

Audit Committee Report

The audit committee is responsible for providing independent, objective oversight for the integrity of the Company’s financial reporting process and internal control system. Other primary responsibilities of the audit committee include the review, oversight and appraisal of the qualifications, independence and audit performance of the Company’s independent registered public accounting firm and providing an open venue for communication among the independent registered public accounting firm, financial and senior management, our internal auditors and the board of directors of the Company. A more detailed description of the responsibilities of the audit committee is set forth in its written charter, which is posted on our website at www.gulfportenergy.com. The following report summarizes certain of the audit committee’s activities with respect to its responsibilities during 2014.

Review with Management and Independent Registered Public Accounting Firm. The audit committee has reviewed and discussed with management and Grant Thornton LLP, an independent registered public accounting firm, the audited consolidated financial statements of the Company for the year ended December 31, 2014.

Controls and Procedures. Management has established and maintains a system of disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed by the Company in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and includes controls and procedures designed to

13

Table of Contents

provide reasonable assurance that information required to be disclosed by us in those reports is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. As of December 31, 2014, management conducted an evaluation of our disclosure controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The audit committee discussed with management and Grant Thornton LLP the quality and adequacy of the Company’s disclosure controls and procedures.

Management has also established and maintains a system of internal controls over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. These internal controls are designed to provide reasonable assurance that the reported financial information is presented fairly, that disclosures are adequate and that the judgments inherent in the preparation of financial statements are reasonable. Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on management’s evaluation under the framework in Internal Control—Integrated Framework, management did not identify any material weaknesses in our internal control over financial reporting and concluded that our internal control over financial reporting was effective as of December 31, 2014, as discussed in more detail in Management’s Report on Internal Control Over Financial Reporting, which was included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on February 27, 2015. Our internal control over financial reporting as of December 31, 2014 has been audited by Grant Thornton LLP, as stated in its attestation report, which was included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on February 27, 2015. The audit committee reviewed and discussed with management and Grant Thornton LLP the Company’s system of internal control over financial reporting in compliance with Section 404 of the Sarbanes-Oxley Act of 2002.

Discussions with Independent Auditing Firm. The audit committee has discussed with Grant Thornton LLP, independent auditors for the Company, the matters required to be discussed by Rules on Auditing Standard No. 16, Communication with Audit Committees, as amended. The audit committee has received the written disclosures and the letter from Grant Thornton LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence and has discussed with that firm its independence from the Company.

Recommendation to the board of directors. Based on its review and discussions noted above, the audit committee recommended to the board of directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Executive Compensation

Compensation Discussion and Analysis

Overview

The compensation discussion and analysis set forth below provides an overview of our compensation program, including the objectives and rationale of each element of compensation, for each of our named executive officers. This section also describes the actions and decisions of the compensation committee of our board of directors, and of our board of directors, as they relate to our executive compensation decisions. The compensation committee, which is composed entirely of independent directors, is primarily responsible for establishing, implementing and monitoring our compensation programs, including those applicable to our executive officers. In particular, the compensation committee’s current role is to oversee, on behalf of our board of directors, our compensation and benefit plans and policies, administer our stock plans (including reviewing and approving equity grants to directors and executive officers), administer our annual cash incentive bonus plans (including the establishment of performance criteria, targets and awards under our 2014 Executive Annual Incentive Compensation Plan) and review and approve annually all compensation decisions relating to our named executive officers. In fulfilling its responsibilities, the compensation committee may delegate any or all of its responsibilities to a member of the committee or to a subcommittee consisting of members of the committee, although no such delegations were made in 2014. The compensation committee meets at least annually to review executive compensation programs, approve compensation levels, consider performance targets, review management performance and administer our equity-based compensation plans and cash incentive bonus plans. The compensation committee operates in accordance with its charter, which was amended and restated in January 2014 and sets forth the committee’s powers and responsibilities, which are described in more detail under the heading “Election of Directors and Director Biographies—What are the committees of the Board?”

As discussed in more detail below under “Employment Agreements—Potential Payments Upon Termination, Resignation or Change of Control—Severance Payments Received by our Former Chief Executive Officer in Connection with Retirement in February 2014,” James D. Palm, our former Chief Executive Officer and a former member of the board of directors, retired from all positions with the Company effective February 15, 2014. We began a nationwide search with Preng & Associates for Mr. Palm’s successor in February 2014, and the board of directors conducted a review of both internal and external candidates. During this interim period, Michael G. Moore, our President and then-Chief Financial Officer, assumed management responsibilities associated with the office and acted as Interim Chief Executive Officer pending the conclusion of the board’s search. Upon the conclusion of this search, the board determined that it is in the best interests of the Company and its stockholders to appoint Mr. Moore as Chief Executive Officer and as a member of our board of directors, and he was appointed to serve in these capacities on April 22, 2014. Mr. Moore has continued to serve as our President. Mr. Moore also continued to serve as our Chief Financial Officer until the appointment of Aaron Gaydosik as our new Chief Financial Officer effective August 11, 2014.

Compensation Philosophy and Objectives

The objectives of our compensation program are to:

The following performance graph compares our cumulative total stockholder return (assuming dividend reinvestment) from January 1, 2010 through January 1, 2015, against the average performance of our 2014 proxy peer group identified by Longnecker & Associates, as described below under “—Compensation Decisions for 2014 and Changes in 2015,” and against the Standard & Poor’s 500 Stock Index, a broad market index, or the S&P 500 Index. The graph assumes an investment of $100 on such date, and that all dividends were reinvested. In 2014 and over this five-year period, we outperformed each of the peer group and the S&P 500 Index.

Compensation Decisions for 2014 and Changes in 2015

Compensation Decisions for 2014

In September 2013, the compensation committee engaged Longnecker & Associates, an independent compensation consulting firm, to, among other things, (i) conduct a peer analysis to aid the committee in

18

Table of Contents

determining the appropriate peer group based on data derived from proxy statements filed by peer companies in 2013 and other publicly available market data, which we refer to as the September 2013 peer group, (ii) conduct an analysis of the Company’s executive compensation for Mr. Palm (our then Chief Executive Officer) and Mr. Moore (our then President and Chief Financial Officer), including with respect to base salary, targeted annual incentives and targeted total direct compensation, (iii) conduct an analysis of the compensation of the board of directors, including with respect to annual retainers, meeting fees, equity grants and total director compensation, (iv) provide the compensation committee with an opinion related to the payout of bonuses, including the analysis performed of market prevalence and competitiveness, and (v) conduct a review of the compensation committee’s charter. In establishing the September 2013 peer group, Longnecker & Associates initially identified candidates of similar size, with similar operations in the onshore oil and gas exploration and production industry, and with similar operations in comparable geographies. Based on Longnecker & Associates’ evaluation, the September 2013 peer group consisted of the following 16 companies: Athlon Energy Inc.; Kodiak Oil & Gas Corp.; Laredo Petroleum Holdings, Inc.; Oasis Petroleum Inc.; Rosetta Resources, Inc.; Denbury Resources Inc.; Energen Corp.; QEP Resources, Inc.; Whiting Petroleum Corp.; Newfield Exploration Co.; Concho Resources, Inc.; Range Resources Corporation; Energy XXI (Bermuda) Limited; SM Energy Company; Cimarex Energy Co.; and Kosmos Energy Ltd. In selecting the September 2013 peer group, Longnecker & Associates sought to include companies that are operationally similar to Gulfport, while maintaining appropriate relative financial alignment. These considerations resulted in the September 2013 peer group including companies that operate in similar plays, focus on onshore exploration and production and have similar reserve and production characteristics (i.e. blend of gas and oil) and market capitalizations that are within a range of 0.5x – 2.0x that of Gulfport’s market capitalization. Longnecker & Associates believed that focusing on companies with similar market capitalization was appropriate for the Company after evaluating its operations and the significant stock price growth the Company has experienced. Given Gulfport’s diverse and unique operational locales, Longnecker & Associates focused on companies with a majority of operations in the continental U.S. rather than in any more specific geographic region. Among the September 2013 peer group, Gulfport falls in the 17th percentile in revenue, 30th percentile in assets, 73rd percentile in market capitalization, 69th percentile in net income and 64th percentile in enterprise value, in each case for the trailing 12 months effective October 8, 2013.

In December 2013, the compensation committee met to consider, among other things, the 2013 compensation analysis prepared by Longnecker & Associates with respect to the compensation of Mr. Moore and our then Chief Executive Officer, Mr. Palm, for 2014. The compensation committee discussed and evaluated the compensation packages for Mr. Moore and Mr. Palm in light of the Company’s performance, the value each such executive brings to the Company, market trends, competitive market data, economic climate, the respective experience and leadership roles of these executives and the Company’s desire to retain these executives. The compensation committee also evaluated the 2014 compensation packages for the members of the board of directors of the Company considering the same factors. The compensation committee noted that the Company demonstrated strong performance metrics compared to its peers. The compensation committee made the 2013 bonus determinations for our then named executive officers, but left the annual base salaries for such named executive officers for 2014 unchanged from the prior year. The compensation committee determined to award each of Messrs. Maier and Baldwin a grant of 40,000 shares of restricted stock under our 2013 Restated Stock Incentive Plan, vesting in three substantially equal installments beginning on December 12, 2013 discussed in more detail below under “—Compensation Components—Long-Term Incentive Compensation,” based on the recommendation of our then-Chief Executive Officer, Mr. Palm, considering their increased role within the organization and their significant contributions to the development of the Company. The compensation committee did not make any other changes to the compensation packages for Messrs. Maier and Baldwin for 2014. Further, the compensation committee deferred any equity award decisions for Mr. Moore and Mr. Palm until such time as the Company’s annual financial and operating results for 2013 were finalized in early 2014.

In February 2014, the compensation committee awarded 24,868 shares of restricted stock to Mr. Moore under our 2013 Restated Stock Incentive Plan as a retention award in connection with his assumption of duties as Interim Chief Executive Officer after the retirement of Mr. Palm and in view of the uncertainty relating to his position in

19

Table of Contents

recognition of the then-ongoing search for a new Chief Executive Officer. The retention award was subject to Mr. Moore’s continuous service with the Company and was to vest in two equal annual installments beginning on February 24, 2015, unless earlier vesting occurred upon his involuntary termination without cause, termination for good reason, death, disability or termination for any reason except cause or voluntary termination without good reason within 24 months after a change in control. As described below, this retention award was rescinded when Mr. Moore was named our Chief Executive Officer.

On April 1, 2014, the compensation committee recommended the approval of, and the board of directors approved, the 2014 Executive Annual Incentive Compensation Plan, subject to stockholder approval at the 2014 Annual Meeting of Stockholders. This plan, which we refer to as our Annual Incentive Plan, was approved in response to general stockholder concerns relating to certain public companies’ practices of awarding guaranteed minimum bonuses to their executives and as part of the Company’s ongoing initiative to revise its cash-based compensation philosophy and programs away from a guaranteed minimum bonus structure to a mix of base compensation and performance based incentive compensation. The Annual Incentive Plan is described in more detail elsewhere in this proxy statement. On April 1, 2014, the compensation committee also determined to provide Mr. Moore, as an additional incentive, a cash retention bonus equal to $400,000 in view of the uncertainty relating to his position in recognition of the then-ongoing search for a new Chief Executive Officer. The cash bonus amount was to vest and become payable in two equal annual installments, beginning on February 24, 2015, subject to Mr. Moore’s continuous service with the Company, unless earlier vesting occurs upon his involuntary termination without cause, termination for good reason, death, disability or termination for any reason except cause or voluntary termination without good reason within 24 months after a change in control. As described below, this cash bonus award was also rescinded when Mr. Moore was named our Chief Executive Officer. In addition, the compensation committee agreed to increase Mr. Moore’s 2013 annual discretionary bonus under his employment agreement from $500,000 to $800,000. This increase was designed to recognize the significant financial and operating performance gains experienced by the Company in 2013, Mr. Moore’s overall performance and the additional duties and responsibilities he assumed upon his appointment as President in August 2013, his service as Chief Financial Officer and Secretary of the Company and his leadership through transformative acquisitions and related capital market transactions in 2013.

On April 22, 2014, Mr. Moore was appointed Chief Executive Officer of the Company. He has continued to serve as President of the Company. Mr. Moore also continued to serve as Chief Financial Officer until the appointment of Aaron Gaydosik as our new Chief Financial Officer effective August 11, 2014. In connection with Mr. Moore’s new responsibilities, we entered into an amended and restated employment agreement with Mr. Moore dated April 30, 2014 but effective April 22, 2014 based on terms recommended by Longnecker & Associates. Material terms of this agreement are discussed below. See “Employment Agreements.”

On July 10, 2014, the Company appointed Mr. Gaydosik as our Chief Financial Officer, effective August 11, 2014. In connection with his appointment, the compensation committee set Mr. Gaydosik’s annual base salary at $300,000, subject to increases as may be determined from time to time by the compensation committee. Under the terms of his employment, Mr. Gaydosik was entitled to receive a one-time sign-on bonus consisting of (i) $150,000 payable in cash and (ii) a restricted stock award valued at $225,000, vesting in two approximately equal annual installments beginning on August 1, 2015 (which was granted to Mr. Gaydosik on February 24, 2015).

The compensation committee also approved Mr. Gaydosik’s participation in the Company’s annual incentive compensation plan, under which he was entitled to receive an annual award representing 50%, 75% or up to a potential maximum of 200% of his base salary, depending on reaching pre-determined financial and/or operational metrics. Mr. Gaydosik was also entitled to receive an annual long-term equity incentive award, consisting of time-vested restricted stock, vesting in three approximately equal annual installments beginning on the date of grant, with a target level of 300% of his annual base salary. The timing and the amount of such annual long-term equity incentive award was to be determined by the compensation committee of the Board in its sole discretion and would be prorated for 2014, based on the number of months served during 2014.

The Company also appointed Mr. Kirtley as the Chief Operating Officer effective April 22, 2014. In connection with his appointment, the compensation committee set his annual base salary at $325,000.

2014 Compensation Analysis and Compensation Decisions for 2015

In the fall of 2014, the compensation committee again engaged Longnecker & Associates to among other things (i) conduct a peer analysis to aid the committee in determining the appropriate peer group, based on data derived from proxy statements filed by peer companies in 2014 and other publicly available market data, (ii) conduct an analysis of the Company’s executive compensation for Mr. Moore, our Chief Executive Officer and President, Mr. Kirtley, our Chief Operating Officer, and Mr. Gaydosik, our Chief Financial Officer, including with respect to base salary, targeted annual incentives and targeted total direct compensation, (iii) conduct an analysis of the compensation of the board of directors, including with respect to annual retainers, meeting fees, equity grants and total director compensation, and (iv) provide the compensation committee with an opinion related to the payout of bonuses, including the analysis performed of market prevalence and competitiveness. In establishing our peer group for 2014, Longnecker & Associates reviewed the September 2013 peer group and removed Athlon Energy Inc., Cimarex Energy Co., Concho Resources, Inc., Energy XXI (Bermuda) Limited, Kodiak Oil & Gas Corp. and Kosmos Energy Ltd. due to either changes in size (primarily in market capitalization) or acquisition of certain of these companies by competitors. Five new companies, Carrizo Oil & Gas, Inc., PDC Energy Inc., SandRidge Energy, Inc., Ultra Petroleum Corp. and WPX Energy, Inc., with operations in the exploration and production industry and similar market capitalization in 2014, were added to our 2014 peer group. Based on Longnecker & Associates’ evaluation, our peer group for 2014 consisted of the following 15 companies: Laredo Petroleum Holdings, Inc.; Oasis Petroleum Inc.; Rosetta Resources, Inc.; Denbury Resources Inc.; Energen Corp.; QEP Resources, Inc.; Whiting Petroleum Corp.; Newfield Exploration Co.; Range Resources Corporation; SM Energy Company; Carrizo Oil & Gas, Inc.; PDC Energy Inc.; SandRidge Energy, Inc.; Ultra Petroleum Corp.; and WPX Energy, Inc. Among our 2014 peer group, Gulfport falls in the 14th percentile in assets, 67th percentile in market capitalization, 43rd percentile in net income (although the lowest in revenue) and 23rd percentile in enterprise value, in each case for the trailing 12 months effective October 21, 2014.

In its 2014 compensation analysis, Longnecker & Associates provided competitive data for similarly situated executives at the peer group companies, focusing on the following elements of compensation: (i) the annual base salary; (ii) the targeted total annual cash compensation consisting of the annual base salary and targeted annual incentive bonus; (iii) the value of long-term incentive awards as of the date of grant; and (v) targeted total direct compensation, consisting of the targeted total annual cash compensation and the value of long-term incentive awards as of the date of grant. The compensation consultant also analyzed how these elements of compensation compare to elements of compensation afforded to our Chief Executive Officer and President, Chief Operating Officer and Chief Financial Officer.

In its analysis, the compensation consultant determined that the 2014 base salary and the targeted total annual cash compensation afforded to our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer were generally in the bottom quartile of being competitive with the peer group. The compensation consultant concluded that the 2014 annual base salaries for each of our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer was below the 25th percentile range of annual base salaries paid to similarly situated executive officers in the peer group. The compensation consultant recommended a multi-year base salary adjustment plan for our Chief Executive Officer, with the goal of achieving alignment between the 25th and 50th percentiles of the peer group within three years. The compensation consultant also recommended that the respective annual base salaries of our Chief Operating Officer and Chief Financial Officer be increased. In the case of our Chief Operating Officer, the compensation consultant recommended aligning his annual base salary closer to the 25th percentile of the peer group and, in the case of our Chief Financial Officer, the compensation consultant recommended a cost of living increase due to his recent hire. The compensation consultant also recommended to align the targeted total cash opportunity for these named executive officers between the 25th and 50th percentiles of the peer group, while allowing the compensation committee to determine the performance targets. The compensation consultant also concluded that current target awards of 150% and 75% of the annual

21

Table of Contents

base salary for our Chief Executive Officer and Chief Financial Officer, respectively, contemplated by the terms of their respective employment were competitive with the peer group. The compensation consultant recommended to establish an annual incentive target of 75% to 85% of the annual base salary for our Chief Operating Officer to align his annual cash incentive opportunity with that of our Chief Financial Officer. The compensation consultant also provided market values with respect to the annual long-term incentive awards granted to similarly situated executives at the peer group companies to assist the compensation committee in making these determinations with respect to our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer for 2015. The compensation consultant concluded that an annual grant of 40,000 shares of our restricted common stock contemplated by the terms of our Chief Executive Officer’s employment agreement is subject to market fluctuations and may not provide a competitive value of long-term incentive to him from one year to the next. The compensation consultant also concluded that the targeted annual equity award representing 300% of his annual base salary contemplated by the terms of our Chief Financial Officer’s employment is competitive with the peer group (falls above the 75th percentile range of the peer group). The compensation consultant recommended that a consistent methodology be implemented by the compensation committee to establish annual long-term incentive grants as a percentage of base salary or as a targeted dollar amount for each of our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer to properly incentivize such named executive officers and make such long-term incentive grants competitive with the peer group.

The compensation committee considered the compensation consultant’s recommendations discussed above and, effective January 1, 2015, increased annual base salaries for our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer to $460,000, $338,000 and $309,000, respectively. Further, on February 24, 2015, the compensation committee granted new restricted stock awards to our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer in the amount of 52,225 shares, 23,025 shares and 21,049 shares, respectively, with the grant date value representing 500% of the annual base salary for our Chief Executive Officer and 300% of the annual base salary for each of our Chief Operating Officer and Chief Financial Officer, to provide further long-term incentive to such named executive officers and align them more closely with the competitive ranges for equity awards afforded to similarly situated executives at peer group companies. For more information regarding these awards, see “—Compensation Components—Long-Term Incentive Compensation—2015 Awards” below. Further, in March 2015, the compensation committee approved our entry into employment agreements with Messrs. Kirtley and Gaydosik to facilitate their retention by the Company, effective April 22, 2014 and August 11, 2014, respectively, and, in April 2015, the compensation committee approved our entry into an amended and restated employment agreement with Mr. Moore, in each such case on the terms consistent with Longnecker & Associates’ recommendations discussed above and, in the case of Mr. Gaydosik, to formalize the terms of his employment we negotiated with Mr. Gaydosik at the time of his appointment as our Chief Financial Officer in August 2014. For a detailed description of these employment agreements, see “Employment Agreements—Employment Agreement with Our Chief Financial Officer and Chief Operating Officer” below.

Compensation Policy

The key elements of our compensation program are base salary, annual bonus and long-term incentive compensation. We use these elements to meet our compensation objectives as follows:

Compensation Components

Base Salary

Base salary is designed to provide basic economic security for our executives and be competitive with salary levels for comparable executives at our peer group companies. As discussed under the heading “Employment Agreements” below, we entered into employment agreements with Mr. Palm, our then Chief Executive Officer, and Mr. Moore, our former Vice President and Chief Financial Officer, in November 2012, and we entered into an amended and restated employment agreement with Mr. Moore effective as of April 22, 2014 in connection with his appointment as our new Chief Executive Officer. As discussed elsewhere in this proxy statement, Mr. Palm retired as our Chief Executive Officer and from our board of directors in February 2014, at which time his employment agreement was terminated. Also, in March 2015, we entered into employment agreements with Mr. Gaydosik, our Chief Financial Officer, and Mr. Kirtley, our Chief Operating Officer, effective as of August 11, 2014 and April 22, 2014, respectively. Under each of these employment agreements, the named executive officer is entitled to a base salary in each year of such executive’s employment agreement, the amount of which is to be reviewed from time to time by the compensation committee and may be adjusted upward, but not downward, by the compensation committee in its sole discretion. In determining the amount of the base salaries of Mr. Moore, Mr. Gaydosik and Mr. Kirtley in connection with the negotiation of their respective employment agreements, the compensation committee considered numerous factors, including the compensation of executive officers of comparable companies within the oil and natural gas industry, Longnecker & Associates’ recommendations, the performance of such executive officer, the experience and leadership qualities of such executive officer, the value such executive officers brought to the Company and the Company’s strategy for recruiting, retaining and motivating key employees. In the future, we anticipate that the compensation committee will continue to review the base salaries of our named executive officers on an annual basis, subject to the terms of any employment agreements that we may have with our named executive officers, and will consider similar factors in making base salary determinations. Under the terms of his amended and restated employment agreement effective April 22, 2014, Mr. Moore’s annual base salary for 2014 remained at $400,000. Mr. Gaydosik’s and Mr. Kirtley’s annual base salaries for 2014 were $300,000 and $325,000, respectively. For additional information, see “—Compensation Decisions for 2014 and Changes in 2015” above. The compensation committee also did not make any changes in the base salary for Messrs. Maier and Baldwin for 2014.

Performance-Based Cash Incentive Compensation

On April 1, 2014, the compensation committee recommended the approval of, and the board of directors approved, the 2014 Executive Annual Incentive Compensation Plan, subject to stockholder approval at the 2014 Annual Meeting of Stockholders. The 2014 Executive Annual Incentive Compensation Plan, which we refer to as the Annual Incentive Plan, is designed to provide an incentive to executive officers and other selected employees of the Company to contribute to the growth, profitability and increased value of the Company by providing cash incentive compensation that may qualify as “performance-based compensation” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code. We adopted the Annual Incentive Plan, in response to certain stockholder concerns, as part of an ongoing initiative to eliminate the use of

24

Table of Contents

minimum discretionary bonus arrangements in the employment agreements of our executive officers in favor of performance-based bonuses.

The Annual Incentive Plan focuses on achievement of certain annual objectives and goals, as determined by the compensation committee at the beginning of each calendar year, and provides that the participants may earn a pre-determined percentage of their respective base salaries for the achievement of such specified goals. Under the Annual Incentive Plan, the payout opportunity is contingent upon meeting the threshold performance levels, and thereafter varies for performance above and below the pre-established target performance levels, subject to a maximum award level. The target award to a participant will represent a percentage of such participant’s base salary, as adjusted based upon meeting or exceeding the performance levels established by the compensation committee for that year, and cannot exceed a maximum payment limit specified by the compensation committee. The terms of the Annual Incentive Plan are described in more detail below.

On April 1, 2014, the compensation committee established the performance criteria and targets for 2014 under the Annual Incentive Plan and specified the weighting attributable to such performance metrics, subject to the approval of the Annual Incentive Plan by the Company’s stockholders at the 2014 annual meeting of stockholders. For 2014, the performance levels require achieving certain financial and operational metrics, including growth in EBITDA, estimated proved reserves and oil and natural gas production, as compared to the prior year period. The compensation committee determined that these metrics were principal drivers of profitability and growth for the Company for 2014. Also on April 1, 2014, the compensation committee granted an award to Michael G. Moore, who at that time was our Interim Chief Executive Officer, President and Chief Financial Officer, under the Annual Incentive Plan, which award represented 50%, 100% or up to a of maximum of 200% of his base salary, depending on reaching the threshold, target or above-target performance levels. Under the terms of Mr. Moore’s amended and restated employment agreement effective April 22, 2014 in connection with his appointment as our Chief Executive Officer, the potential amount of the award was increased to 75%, 150% or up to a maximum of 300% of his base salary, subject to the same performance criteria and targets established by the compensation committee on April 1, 2014. In connection with Mr. Gaydosik’s appointment as our Chief Financial Officer effective August 11, 2014, the compensation committee approved Mr. Gaydosik’s participation in the Company’s annual incentive compensation plan, under which he was entitled to receive an annual award representing 50%, 75% or up to a maximum of 200% of his base salary depending on reaching pre-determined financial and/or operational metrics, which provision was formalized in Mr. Gaydosik’s employment agreement. Under the terms of the employment agreement with Mr. Kirtley, Mr. Kirtley was entitled to an annual award under the Annual Incentive Plan representing 50%, 75% or up to a maximum 200% of his annual base salary subject to the same performance criteria and targets established by the compensation committee on April 1, 2014. Straight line interpolation applied to determine the amount of the bonus for performance that is above the threshold target and between performance levels for each of these named executive officers. The compensation committee believes that performance-based cash incentive compensation, with meaningful performance targets, will further align our executives’ interests with those of our stockholders, motivate our executives to contribute to the Company’s growth and profitability and link a larger portion of our executives’ compensation to the performance of the Company. On February 24, 2015, the compensation committee certified to the attainment of the pre-established performance goals and targets for 2014, which were achieved at the above-target levels but slightly below the maximum level for both growth in EBITDA and oil and natural gas production and at a maximum level for the growth of estimated proved reserves. In connection with reaching these goals, the compensation committee approved awards to Mr. Moore, Mr. Kirtley and Mr. Gaydosik, representing 275.5%, 137.75% and 137.75%, respectively, of their annual base salaries for 2014, except that our Chief Financial Officer’s annual base salary for 2014 was prorated to reflect his appointment in this capacity effective August 11, 2014. For information regarding the performance-based cash incentive bonuses awarded to our named executive officers for 2014, see “Compensation Tables—2014, 2013 and 2012 Summary Compensation Table” below.

Table of Contents

PAY FOR PERFORMANCE

On March 30, 2015, the compensation committee established the performance criteria and targets for 2015 for the named executive officers and other covered employees under the Annual Incentive Plan and specified the weighting attributable to such performance metrics. Similar to 2014, the performance levels for 2015 require achieving certain financial and operational metrics. For 2015, these performance factors include growth in estimated proved reserves and oil and natural gas production. The compensation committee believes that these performance levels, as well as bonus compensation targets set forth in our named executive officers’ employment agreements, as may be adjusted by the compensation committee from time to time, will continue to (i) further motivate our named executive officers to contribute to the Company’s performance and growth, (ii) align our named executive officers’ interests with those of our stockholders and (iii) put a larger portion of our named executives’ compensation at risk.

Long-Term Incentive Compensation

Long-Term Incentive Policy. Although in the past we awarded both options and restricted stock as part of our long-term incentive compensation program, our board of directors and the compensation committee believe that restricted stock awards are an essential component of our compensation strategy, and currently intend to primarily offer such awards in the future. Further, we anticipate that any equity awards granted to our executive officers during 2015 will be in the form of restricted stock. The compensation committee may also determine to issue other forms of stock-based awards to our named executive officers or other eligible participants under our 2013 Restated Stock Incentive Plan or other equity incentive plans in effect at that time. Our current equity incentive plan is described below under the heading “Benefit Plans—2013 Restated Stock Incentive Plan” below. The compensation committee did not establish any objective performance targets for 2014 or 2015 with respect to our executive officers’ equity incentive compensation.

2014 Awards. In 2014, the compensation committee reviewed and discussed the Company’s current equity compensation plan and objectives. The compensation committee also considered the need to issue new equity awards as old awards become fully vested to provide future incentives to our executive officers. As discussed above, on February 24, 2014, the compensation committee granted 24,868 shares of restricted stock to Mr. Moore under the 2013 Restated Stock Incentive Plan as a retention award in connection with his assumption of duties as interim Chief Executive Officer after the retirement of Mr. Palm and in view of the uncertainty relating to his position in recognition of the then-ongoing search for a new Chief Executive Officer. The retention award was subject to Mr. Moore’s continuous service with the Company and was to vest in two equal annual installments beginning on February 24, 2015, unless earlier vesting occurred upon his involuntary termination without cause, termination for good reason, death, disability or termination for any reason except cause or voluntary termination without good reason within 24 months after a change in control. This retention award was rescinded when Mr. Moore was named our Chief Executive Officer. On April 30, 2014, the compensation committee granted Mr. Moore 40,000 shares of restricted stock in connection with his appointment as our new Chief Executive Officer, of which shares 13,333 vested on May 12, 2014, 13,333 vested on April 22, 2015 and

26

Table of Contents

the remaining 13,334 will vest on April 22, 2016. On January 31, 2014, Mr. Palm was granted 80,000 shares of our restricted stock units granted under our 2013 Restated Stock Incentive Plan in connection with his retirement, which shares vest in three substantially equal annual installments beginning on February 15, 2015, subject to certain forfeiture provisions. See the description of Mr. Palm’s severance agreement below under the heading “Employment Agreements—Potential Payments Upon Termination, Resignation or Change of Control—Severance Payments Received by our Former Chief Executive Officer in Connection with Retirement in February 2014.” Since each of Messrs. Maier and Baldwin received a restricted stock award of 40,000 shares of restricted common stock in December 2013, vesting in three substantially equal annual installments beginning on December 12, 2013, the compensation committee did not grant any additional equity awards to these named executive officers in 2014.

2015 Awards. In February 2015, the compensation committee granted new restricted stock awards to our Chief Executive Officer, Chief Financial Officer and Chief Operating Officer in the amount of 52,225 shares, 21,049 shares and 23,025 shares, respectively, to provide further long-term incentive to such named executive officers and align them more closely with the competitive ranges for equity awards afforded to similarly situated executives at peer group companies based on Longnecker and Associates’ recommendation. These restricted stock awards vest in three approximately equal annual installments beginning, in the case of our Chief Executive Officer, on March 1, 2015 and, in the case of the two other named executive officers referenced above, beginning on March 1, 2016. Further, in February 2015, the compensation committee granted 3,297 shares of our restricted common stock to Mr. Gaydosik to which Mr. Gaydosik was entitled upon commencement of his employment with us on August 11, 2014, but which were not granted until February 2015. Of these shares of restricted common stock, 1,964 will vest on August 1, 2015 and the remaining 1,963 will vest on August 1, 2016.

Termination and Change of Control Benefits

Our employment agreement with Mr. Moore provides for specified payments and benefits upon certain termination events, including termination following a change of control. This employment agreement contains termination and change of control provisions that we believe are comparable to similar provisions employed by a majority of the companies in our industry peer group. The compensation committee believes that this agreement will encourage Mr. Moore to remain in our employment 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 executives to act in the best interests of stockholders without distraction based on uncertainty regarding their employment status.

We did not have an employment agreement with Mr. Kirtley, Mr. Maier or Mr. Baldwin at December 31, 2014, but, under the terms of the restricted stock awards made to them, the shares of restricted stock may be accelerated in the discretion of the compensation committee upon a change of control. The value of the unvested restricted stock held by Mr. Kirtley, Mr. Maier and Mr. Baldwin was $459,182, $765,261 and $695,681, respectively, as of December 31, 2014. See “Employment Agreements—Potential Payments Upon Termination, Resignation or Change of Control.”

In connection with Mr. Gaydosik’s appointment as our Chief Financial Officer effective August 11, 2014, the compensation committee determined that Mr. Gaydosik would be entitled to certain termination benefits. If Mr. Gaydosik’s employment with the Company or its successor was terminated within 18 months (extended to 24 months in his employment agreement discussed below) of the date of occurrence of a change in control, Mr. Gaydosik would have been eligible to receive a cash payment equal to two times his annual base salary and target annual incentive bonus, which would have been $1,050,000, if he was terminated under these circumstance on December 31, 2014. In addition, upon such termination following a change in control, all equity awards that had been granted to Mr. Gaydosik prior to such termination would have been immediately vested on the date of termination and he would have been entitled to continuous medical coverage under COBRA valued at $30,561. If, in the absence of a change in control, Mr. Gaydosik’s employment with the Company was terminated for any

27

Table of Contents

reason other than for cause, he would have received severance in an amount equal to one year of his annual base salary and target annual incentive bonus, which at December 31, 2014 would have been $525,000. In addition, all equity awards that had been granted to Mr. Gaydosik prior to such termination would have immediately vested on the date of termination, having a value of $0 as of December 31, 2014, and he would have been entitled to one-year continuation of benefits valued at $19,975 as of December 31, 2014.

In March of 2015, we entered into an employment agreement with each of Mr. Gaydosik and Mr. Kirtley containing, among other things, certain change in control provisions. For more information regarding such change in control provisions, see “Employment Agreements—Employment Agreement with Our Chief Financial Officer and Chief Operating Officer” below.

Perquisites and Other Personal Benefits

We provide certain of our named executive officers with a limited number of perquisites or other personal benefits, primarily consisting of life insurance premiums and, in the case of Mr. Palm, prior to his retirement as our Chief Executive Officer, Mr. Moore, our current Chief Executive Officer and President, and Mr. Kirtley, our Chief Operating Officer, a company vehicle, that we believe help provide a competitive package of compensation and benefits. The value of these benefits is disclosed in the Summary Compensation Table below.

Broad-Based Employee Benefits

401(k) Plan. We have a retirement savings plan in which our named executive officers currently participate. The retirement plan is a tax qualified 401(k) plan that covers all eligible employees including the named executive officers. Under the plan, we make a safe harbor contribution equal to 3% of each eligible employee’s gross annual compensation for the prior calendar year. We also have the ability to make an additional, discretionary contribution that is allocated based on each eligible employee’s gross annual compensation for the prior calendar year. Both contributions are or may be made regardless of employee’s deferrals into the plan. In 2014, we made safe harbor and discretionary contributions totaling 3% of eligible compensation for eligible employees, subject to certain limitations provided by our 401(k) plan and Internal Revenue Service regulations. All contributions made by us on behalf of an employee are 100% vested when contributed. For more details regarding our 401(k) plan, see “Benefit Plans—401(k) Plan” below.

Other Benefits. Our named executive officers are eligible to participate in all of our other employee benefit plans which include medical, dental, group life, disability and accidental death and dismemberment insurance, in each case on the same basis as all other employees.

Effect of Our Compensation Policies and Practices on Risk and Risk Management

The compensation committee reviews the risks and rewards associated with our compensation policies and programs. We believe that such policies and programs encourage and reward prudent business judgment and avoid encouraging excessive risk-taking over the long term. With respect to specific elements of compensation:

28

Table of Contents

Based on the foregoing, the compensation committee believes that the Company does not utilize compensation policies and programs creating risks that are reasonably likely to have a material adverse impact on the Company.

Deductibility of Executive Compensation

Section 162(m) of the Code limits the deductibility for federal income tax purposes of executive compensation paid to the Chief Executive Officer and the three other most highly compensated officers (other than the Chief Executive Officer and the Chief Financial Officer) of a public company to $1,000,000 per year, but contains an exception for certain performance-based compensation. Our policy is to periodically review and consider whether particular compensation and incentive payments to our executives will be deductible for federal income tax purposes. We intend, to the extent feasible and when we believe it is in the best interests of the Company and its stockholders, to attempt to qualify executive compensation as tax deductible where it does not adversely affect the development and execution of our compensation plans. However, the compensation committee may from time to time approve non-deductible payments in order to maintain flexibility in structuring appropriate compensation programs in the interests of the Company and our stockholders. For example, the compensation committee has in the past granted stock options with time based vesting provisions that would be considered performance based compensation, but in recent years has granted restricted stock that is subject to time based vesting and does not constitute performance based compensation that will satisfy the exception to the deduction limit.

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.” Non-vested shares are deemed issued and outstanding from a legal perspective; however, 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 Role of Stockholders’ Say-on-Pay Vote

We provide our stockholders with the opportunity to cast an annual advisory vote on executive compensation (a “say-on-pay proposal”) in accordance with the Dodd-Frank Act. At our June 2011 annual meeting of stockholders, our stockholders expressed substantial support for the compensation of our named executive officers, with approximately 99.7% of the votes cast for approval of the “say-on-pay” advisory vote. The compensation committee evaluated the results of the 2011 “say-on-pay” advisory vote at its October 2011 meeting. At our June 2012, 2013 and 2014 annual meetings of stockholders, our stockholders again expressed support for the compensation of our named executive officers, with approximately 94.4%, 63.6% and 91.1%, respectively, of the votes cast for approval of the “say-on-pay” advisory vote. The compensation committee believes that these prior results of the “say on pay” advisory votes affirm our stockholders’ support of our executive compensation policies and practices, but the compensation committee has implemented the Annual Incentive Plan to more closely align our executives’ interests with those of our stockholders and to link a larger portion of our executives’ compensation to the performance of the Company. The Annual Incentive Plan was approved in response to general stockholder concerns relating to certain public companies’ practices of awarding guaranteed minimum bonuses to their executives and as part of our broader initiative to revise the Company’s cash-based compensation philosophy and programs away from a guaranteed minimum bonus structure to a mix of base compensation and performance based incentive compensation. The compensation committee also has committed to eliminate the use of minimum discretionary bonus arrangements in future employment agreements, in recognition of the Company’s shift to the use of performance-based bonuses. The compensation committee believes that our executive compensation policies and practices, including the Annual Incentive Plan, approved by our board of directors on April 1, 2014 and by our stockholders on June 12, 2014, and our shift away from discretionary bonus arrangements, are appropriate and reasonably consistent with market practices and with the long-term interests of the Company and its stockholders. The compensation committee will continue to consider the outcome of our stockholders’ future “say-on-pay” votes when making compensation decisions for our named executive officers.

Benefit Plans

401(k) Plan

We maintain a retirement savings plan, or a 401(k) Plan, 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 following year, we make a safe harbor contribution equal to 3% of each eligible employee’s eligible annual compensation for the prior calendar year. We also have the ability to make an additional, discretionary contribution based on each eligible employee’s eligible annual compensation for the prior calendar year. Both contributions are made, regardless of employee’s deferrals into the plan. In 2014, we made safe harbor and discretionary contributions totaling 3% of eligible compensation for eligible employees, subject to certain limitations provided by our 401(k) plan and Internal Revenue Service regulations. All contributions made by us on behalf of an employee are 100% vested when contributed. The 401(k) Plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As such, contributions to the 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) Plan, and all contributions are deductible by us when made.

2013 Restated Stock Incentive Plan

Our 2013 Restated Stock Incentive Plan, which amended and restated our Amended and Restated 2005 Stock Incentive Plan, was adopted to enable us, and any of our affiliates, to attract and retain the services of the types of employees, consultants and directors who will contribute to our long range success and to provide incentives which are linked directly to increases in share value which will inure to the benefit of our stockholders. The plan provides a means by which eligible recipients of awards may be given an opportunity to benefit from increases in value of our common stock through the granting of incentive stock options, nonstatutory stock options, restricted awards (restricted stock and restricted stock units), performance awards and stock appreciation rights. Our compensation committee serves as the plan administrator.

Eligible award recipients are employees, consultants and directors of ours and any present or future parent or subsidiary of ours. Incentive stock options may be granted only to our employees. Awards other than incentive stock options may be granted to employees, consultants and directors. The shares that may be issued pursuant to awards consist of our authorized but unissued common stock, and the maximum aggregate amount of such common stock which may be issued upon exercise of all awards in the plan, including incentive stock options, may not exceed 7,500,000 shares, subject to adjustment to reflect certain corporate transactions or changes in our capital structure. For a description of the awards granted under the plan to our named executive officers, see “Executive Compensation—Compensation Decisions for 2014 and Changes in 2015—Compensation Policy—Align the interests of our executives with those of our stockholders—Restricted Stock Awards” above. On April 1, 2015, 5,000 shares were issuable upon exercise of outstanding options and 1,397,554 shares of restricted common stock had been granted under this plan. There were 4,373,590 shares available for future grants under this plan as of April 1, 2015.

In the event of a transaction involving a change in control (as defined in the plan) of the Company, a dissolution or liquidation of the Company, an exchange of shares or any corporate separation or division, including, but not limited to, a split-up, a split-off or a spin-off, or a sale, in one transaction or a series of related transactions, of all or substantially all of our assets or a merger, consolidation, or reverse merger in which we are not the surviving entity, then all outstanding stock awards under our 2013 Restated Stock Incentive Plan may, in the sole discretion of the plan administrator, be assumed, continued, or substituted for by any surviving or acquiring entity (or its parent company), or may be cancelled either with or without consideration for the vested portion of the awards. In the event an option award would be cancelled without consideration paid to the extent vested, the option award recipient may exercise the option award in full or in part for a period of ten days. The plan administrator may also exercise its discretionary authority to accelerate the vesting of an award under our 2013 Restated Stock Incentive Plan in the event of a change in control.

2014 Executive Annual Incentive Compensation Plan

The Annual Incentive Compensation Plan, or Annual Incentive Plan, was approved by our board of directors on April 1, 2014 and by our stockholders at the 2014 Annual Meeting on June 11, 2014. The Annual Incentive Plan is effective as of April 1, 2014 with respect to the fiscal year performance period beginning January 1, 2014.

Our executive officers and selected employees and those of our subsidiaries are eligible to receive awards under the Annual Incentive Plan. The Annual Incentive Plan provides for awards of incentive compensation that are contingent on the attainment of specific performance targets. Under the Annual Incentive Plan, the compensation committee, as the plan administrator, establishes the performance targets for each award and the performance period during which the performance is to be measured, which will generally be our fiscal year. Performance targets may include a minimum level of performance below which no payment will be made, levels of performance at which specified percentages of the award will be paid, and a maximum level of performance above which no additional award will be paid. The plan administrator must adopt the performance targets and criteria for awards granted to executive officers subject to the limits of Section 162(m) of the Code, whom we refer to as Covered Employees, no later than the earlier of:

In addition, award amounts to be paid to any Covered Employee for any one year may not exceed the lesser of: (i) 300% of base salary at the time the award is established, or (ii) $6.0 million. Individual awards may be subject to lesser limits as specified in the discretion of the compensation committee.

Performance targets for each award will be based on pre-established performance factors, which may include any or all of the following, individually or in combination:

37

Table of Contents

These performance factors may relate to the performance of the Company or the performance of a business unit, product line, territory or any combination of these. Performance targets for employees who are not executive officers may also be based on other additional objective or subjective performance criteria established by the plan administrator.

The plan administrator may at any time establish additional conditions and terms of payment of awards, including additional financial, strategic or individual goals, which may be objective or subjective. The plan administrator may exercise negative discretion to reduce the amount of an award, but may not adjust upwards the amount payable pursuant to any award to a Covered Employee, nor may it waive the achievement of the performance target requirement for any Covered Employee, except in the case of the death or disability of the participant or a change in control of the Company.

Unless the plan administrator provides otherwise, a participant must be employed by us on the date that awards are paid to receive an award payment, except in the case of death or disability. If a participant dies or becomes disabled during a performance period, the participant (or the participant’s beneficiary) will receive a pro-rated award payment at the same time all other awards are paid for the performance period. In the event of a change in control, each named executive officer will be paid the target award amount (mid-point of any specified range of potential award payment amount) based on the assumption that the performance target was attained at the target level (mid-point of any specified range of performance targets) for the entire performance period. The target award amount will be paid within ten (10) days following the consummation of the change in control transaction.

Before payment of any award to a Covered Employee, our compensation committee must certify in writing that the performance target requirement for such award was met.

The plan administrator may at any time amend the Annual Incentive Plan, subject to approval by our stockholders to the extent stockholder approval is necessary to continue to qualify as “performance-based compensation” under Section 162(m) of the Code. The plan administrator may at any time 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 compensation committee is expected to consist solely of two or more “outside directors” within the meaning of Section 162(m) of the Code. 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:

Federal Income Tax Consequences of the Annual Incentive Plan.

Under federal income tax laws currently in effect:

Participants in the Annual Incentive Plan will recognize in the year of payment ordinary income equal to the award amount, which is subject to applicable income and employment tax withholding by us (including the additional tax of 0.9% imposed on wages in excess of $200,000 under Section 3101(b)(2) of the Code). Under current regulations and guidance, we expect that awards under the Annual Incentive Plan will not be subject to Section 409A of the Code, which imposes restrictions on nonqualified deferred compensation arrangements and penalizes participants for violating these restrictions.

Section 162(m) of the Code imposes a $1.0 million annual limit on the amount of compensation that we may deduct for federal income tax purposes with respect to our chief executive officer and each of our three highest compensated officers (other than our chief executive officer and our chief financial officer), subject to certain exceptions. The Annual Incentive Plan is intended to qualify for the exception under Section 162(m) for “performance-based compensation.” We expect that we will be entitled to a tax deduction in connection with the payment of each award under the Annual Incentive Plan in an amount equal to the ordinary income realized by the participant without regard to the $1.0 million annual deduction limitation under Section 162(m) of the Code, if certain requirements of Section 162(m) are satisfied. However, the plan administrator may award compensation that is or may become non-deductible, and expects to consider whether it believes such grants are in the best interest of the Company, balancing tax efficiency with long-term strategic objectives. While the plan administrator is mindful of the limitation imposed by Section 162(m) of the Code, it also recognizes that facts and circumstances may render compliance with those limitations inappropriate, at odds with the best interests of the Company or out of step with the then-prevailing competitive market conditions. In such event, the plan administrator’s priority will be determining what is in the best interest of the Company and its stockholders rather than compliance with the technical limitations imposed by the Code.

EQUITY COMPENSATION PLAN INFORMATION

The following table sets forth, as of December 31, 2014, certain information with respect to all compensation plans under which equity securities are authorized for issuance.

Employment Agreements

Employment Agreement with Our Chief Executive Officer

Effective April 22, 2014, we entered into an amended and restated employment agreement with Mr. Moore in connection with his new responsibilities as Chief Executive Officer. The employment agreement was further amended and restated as of April 29, 2015 to reflect recommendations of the compensation consultant that were approved by the compensation committee. The agreement has a three-year term commencing effective April 22, 2014 and provided for an annual base salary of $400,000 that can be increased from time to time by the compensation committee, but not decreased. The agreement, as amended and restated as of April 29, 2015, reflects the compensation committee’s decision to increase Mr. Moore’s annual base salary to $460,000 for 2015 and the determination by the compensation committee to continue to increase Mr. Moore’s annual base salary during 2016 and 2017 so as to achieve alignment between the 25th and 50th percentile of our compensation peer group disclosed in our annual proxy statement (as it may be adjusted from time to time). Mr. Moore is also entitled to receive a target annual bonus of 150% of his base salary upon achievement of performance goals established by the compensation committee. The annual bonus may be less than, or more than, the 150% target, up to a maximum of 300% of base salary in the event performance exceeds the target level established by the compensation committee. The agreement also provided that he would be entitled to receive annual grants of 40,000 shares of restricted stock that would vest in three substantially equal annual installments commencing in the year granted. The agreement, as amended and restated as of April 29, 2015, eliminates Mr. Moore’s right to receive a fixed annual grant of 40,000 shares of restricted stock. Instead, consistent with the recommendation of the compensation consultant and approved by the compensation committee, the agreement now provides that Mr. Moore is entitled to receive an award of restricted stock equal to 500% of his annual base salary. The vesting schedule remained unchanged. Mr. Moore is also entitled to five weeks of paid vacation, to participate in such medical insurance and other welfare benefit plans that we establish from time to time, a $500,000 life insurance policy and to the use of a company vehicle. Mr. Moore is subject to certain restrictive covenants in his employment agreement, including a restriction on using our trade secrets and a 12-month restriction on solicitation of our employees, consultants and customers.

Rights Upon Termination Without Cause, Resignation for Good Reason or Death or Disability

The continued employment of Mr. Moore with us is “at-will,” meaning that either we or Mr. Moore may terminate the employment relationship at any time and for any reason, with or without notice. However, under the terms of his amended and restated employment agreement, if (i) we terminate Mr. Moore without “cause,” (ii) Mr. Moore terminates his employment for “good reason” or (iii) Mr. Moore’s employment is terminated due to death or disability, then, subject to Mr. Moore signing and delivering a general release of any and all claims against us, the following would occur:

For purposes of the employment agreement with Mr. Moore, “cause” is generally defined as:

“Good reason,” as used in the employment agreement with Mr. Moore, means (i) a material diminution in the duties, authority or responsibilities of Mr. Moore or a material breach of the employment agreement by the Company, or (ii) requiring Mr. Moore to relocate his principal place of employment to a location that is more than 35 miles from the location of the Company’s principal office in the Oklahoma City area as of the effective date of the employment agreement, provided that the Company fails to cure such material diminution, breach or relocation within 30 days of receipt of a written notice from Mr. Moore.

Rights Upon Termination for Cause or Resignation Other than for Good Reason

Under the terms of our employment agreement with Mr. Moore, in the event Mr. Moore is terminated for “cause” or Mr. Moore voluntarily terminates his employment other than for “good reason,” Mr. Moore would be entitled

41

Table of Contents

to a lump sum payment on the termination date equal to all accrued and unpaid salary and other compensation payable to Mr. Moore (including vacation and sick pay) with respect to services rendered through the termination date and, subject to Mr. Moore signing a general release of any and all claims against us and, as consideration for such release, an amount equal to his base salary amount in effect immediately preceding such termination pro rated based on the number of days between the first day of the contract year and the termination date, divided by 365.

Rights Upon Termination Following a Change of Control

Under the terms of our employment agreement with Mr. Moore, if Mr. Moore’s employment with the Company or its successor is terminated on or before the second anniversary of the date of occurrence of a “change of control” either (a) by the Company or its successor other than for “cause,” (b) by Mr. Moore for “good reason,” or (c) as a result of Mr. Moore’s death or disability, then, in addition to the benefits described under the heading “—Rights Upon Termination Without Cause, Resignation for Good Reason or Death or Disability” above:

Under the terms of Mr. Moore’s employment agreement, any equity awards granted on or after the date of the agreement will provide that such equity awards will vest upon the occurrence of a change of control. A “change of control” will be deemed to have occurred upon the occurrence of any of the following:

Employment Agreement with our Chief Financial Officer and Chief Operating Officer

On March 13, 2015, we entered into an employment agreement with Aaron Gaydosik, our Chief Financial Officer. The employment agreement provides for a three-year term commencing as of August 11, 2014, which will be extended for successive one-year periods unless we or the executive elects to not extend the term. Mr. Gaydosik’s initial annual base salary was $300,000, increasing to $309,000 effective January 1, 2015, which can be increased from time to time by the compensation committee, but not decreased. Subject to the achievement of certain performance goals as determined by our board of directors or the compensation committee for each fiscal year, Mr. Gaydosik is eligible to receive a target annual bonus of 75%, and a maximum target bonus of up to 200%, of his annual base salary, provided he remains employed by us on the payment date. Mr. Gaydosik is also entitled to participate in any life and medical insurance plans and other similar plans that we establish from time to time for our executive employees.

42

Table of Contents

Under his employment agreement, Mr. Gaydosik is eligible to participate in our 2013 Restated Stock Incentive Plan or such other equity incentive plan or plans then in existence for the benefit of employees, and may in the discretion of the compensation committee receive an equity award, with a target level of 300% of his base salary, in accordance with the terms of such plan or plans. The timing and amount of such equity awards, any target performance goals and the vesting terms of such awards will be determined by the compensation committee in its sole discretion. If Mr. Gaydosik’s employment terminates prior to any scheduled vesting date then, except if he is involuntarily terminated without “cause” (as defined below) or as expressly provided in any existing or future equity award, he will forfeit all rights and interests in and to such unvested equity awards. If Mr. Gaydosik is terminated for “cause,” he will forfeit all rights and interests in and to all outstanding equity awards, whether vested or unvested.

Mr. Gaydosik has agreed to certain restrictive covenants in his employment agreement, including, without limitation, his agreement not to compete with us, not to interfere with any of our employees, suppliers or regulators and not to solicit our customers or employees, in each case during Mr. Gaydosik’s affiliation with us and for a period of 12 months thereafter. Mr. Gaydosik’s continued employment with us is terminable by either party. We may terminate Mr. Gaydosik’s employment at any time, with or without advance notice. Mr. Gaydosik may terminate the employment relationship at any time and for any reason. However, if (i) we terminate Mr. Gaydosik’s employment without “cause,” or (ii) Mr. Gaydosik resigns for “good reason” (as defined below), then Mr. Gaydosik will be entitled to severance pay in an amount equal to 12 months’ base salary plus target bonus; provided, in each case, that the executive continues to comply with the restrictive covenants described above and the executive executes a full general release in our favor, except that the restriction on competition will not apply in the event the executive resigns for good reason within 12 months following our change of control. In the event Mr. Gaydosik’s employment is terminated for “cause” (as defined below), our obligations will terminate with respect to the payment of any base salary or bonuses effective as of the termination date.

If Mr. Gaydosik’s employment with us or our successor is terminated on or before the second anniversary of the date of occurrence of a “change of control” (as defined below) either (a) by us or our successor other than for “cause” or (b) by Mr. Gaydosik for “good reason,” then, in addition to the benefits described above, (i) all equity awards that have been granted to Mr. Gaydosik that would have vested at any time after the date of Mr. Gaydosik’s termination solely as a result of Mr. Gaydosik’s continued service to the Company will immediately vest on the date of termination, and (ii) Mr. Gaydosik will be entitled to receive a lump sum payment equal to his base salary and target annual bonus during the two year period after his termination and the continuation of COBRA coverage for 18 months.

On March 13, 2015, we entered into an employment agreement with Ross Kirtley, our Chief Operating Officer. The employment agreement provides for a two-year term commencing as of April 22, 2014, which will be extended for successive one-year periods unless we or the executive elects to not extend the term. Mr. Kirtley’s initial annual base salary was $325,000, increasing to $338,000 effective January 1, 2015, which can be increased from time to time by the compensation committee, but not decreased. Subject to the achievement of certain performance goals as determined by our board of directors or the compensation committee for each fiscal year, Mr. Kirtley is eligible to receive a target annual bonus of 75%, and a maximum target bonus of up to 200%, of his annual base salary, provided he remains employed by us on the payment date. Mr. Kirtley is also entitled to participate in any life and medical insurance plans and other similar plans that we establish from time to time for our executive employees.

Under his employment agreement, Mr. Kirtley is eligible to participate in our 2013 Restated Stock Incentive Plan or such other equity incentive plan or plans then in existence for the benefit of employees, and may in the discretion of the compensation committee receive an equity award, with a target level of 300% of his base salary, in accordance with the terms of such plan or plans.

Prior Employment Agreement with our Former Chief Executive Officer

Effective November 1, 2012, we entered into an employment agreement with James D. Palm. His employment agreement had an initial term of three years and automatically renewed for successive one-year terms thereafter unless either we or the executive gave notice to the other party of our or the executive’s election, as the case may be, to not renew the agreement. Mr. Palm was initially entitled to a base salary of $300,000, which amount could be increased, but not decreased, by the compensation committee in its sole discretion. In February 2013, the compensation committee increased the base salary for Mr. Palm to $400,000. In addition, Mr. Palm was entitled to receive an annual discretionary cash bonus, the amount of which to be determined by the compensation committee, provided that such amount would not be less than $500,000 each year. Mr. Palm was also entitled to participate in the Company’s equity incentive plan. Whether an executive received an equity award under the incentive plan, and the timing and amount of any such award, was to be determined by the compensation committee in its sole discretion. Other benefits afforded to each executive under the terms of his employment agreement included four weeks of paid vacation each year, participation in all group health plans of the Company then in effect, entitlement to receive life insurance coverage providing a death benefit of not less than $500,000 and participation in all retirement plans of the Company then in effect. Mr. Palm agreed to certain restrictive covenants in his employment agreement, including, without limitation, his agreement to not (i) disclose trade secrets or confidential information during the term of employment and so long thereafter as such trade secrets or information are not generally known to the public, (ii) compete with the Company while making use of trade secrets of the Company at any time and (iii) solicit any employees, agents, consultants, customers or clients of the Company for the term of his employment with the Company plus twelve months thereafter.

As discussed elsewhere in this proxy statement, the employment agreement with Mr. Palm was terminated on the date of his resignation as the Chief Executive Officer of the Company in February 2014 in connection with his retirement. The description of the separation agreement entered into with Mr. Palm in connection with his retirement are discussed below under the heading “—Potential Payments Upon Termination, Resignation or Change of Control.”

Potential Payments Upon Termination, Resignation or Change of Control

The following table provides information regarding potential payments as of December 31, 2014 to each of our named executive officers with whom we had an employment agreement as of December 31, 2014 in connection with certain termination events, including a termination related to a change of control of the Company.

Severance Payments Received by our Former Chief Executive Officer in Connection with Retirement in February 2014

As previously disclosed, on January 29, 2014, we announced that Mr. Palm, our former Chief Executive Officer and a former member of the Board of Directors, informed us of his decision to retire from all positions he held with the Company, effective as of February 15, 2014. In connection with Mr. Palm’s retirement, we entered into a separation and release agreement with Mr. Palm, which we refer to as the Separation Agreement, pursuant to which Mr. Palm has agreed, among other things, to provide such advice and transition assistance to the board of directors and management of the Company as may be requested by the Company from time to time and not to compete with the Company, in each case for a period of three years commencing on Mr. Palm’s retirement date. Under the Separation Agreement, we agreed to provide Mr. Palm with certain compensation and benefits in satisfaction of all contractual obligations under Mr. Palm’s existing employment agreement with the Company and in exchange for the non-competition obligations and the transition services to be provided by Mr. Palm to us during the non-compete period under the Separation Agreement, including: (i) all of Mr. Palm’s accrued but unpaid salary and unreimbursed expenses through Mr. Palm’s retirement date, (ii) health care benefits for Mr. Palm and his dependents for up to

46

Table of Contents

eighteen (18) months following his retirement date, (iii) a lump-sum cash payment of $1,800,000, (iv) $200,000 per year for a period of three years in consulting and non-competition fees, payable in arrears in three equal annual installments beginning on February 15, 2015 and (v) a restricted stock unit award for 80,000 shares of the Company’s common stock, which will vest in three substantially equal annual installments beginning on the first anniversary of Mr. Palm’s retirement date, provided, however, that the payments specified in clause (iv) and the vesting of common stock specified in clause (v) are contingent upon Mr. Palm’s compliance with his obligations under the Separation Agreement and in the event of a violation of these obligations any unpaid payments and unvested common stock will be forfeited. In addition, under the Separation Agreement, all unvested stock options, restricted stock or any other equity awards that had previously been granted to Mr. Palm became fully vested as of his retirement date. Under the Separation Agreement, Mr. Palm is subject to certain covenants regarding non-competition, ownership of inventions, confidentiality and non-solicitation. The Separation Agreement also contains customary waiver and release provisions pursuant to which Mr. Palm waived, released and discharged the Company and certain other related parties from any and all claims that Mr. Palm may have had against the Company or such other parties as of the date of the Separation Agreement.

Change of Control Arrangements with Other Named Executive Officers

We did not have an employment agreement with either Mr. Kirtley, Mr. Maier or Mr. Baldwin at December 31, 2014 but, under the terms of the restricted stock awards made to Mr. Kirtley, Mr. Maier and Mr. Baldwin, the shares of restricted stock held by Mr. Kirtley, Mr. Maier and Mr. Baldwin may be accelerated in the discretion of the compensation committee upon a change of control. The value of the restricted stock held by Mr. Kirtley, Mr. Maier and Mr. Baldwin was $459,182, $765,261 and $695,681, respectively, as of December 31, 2014.

In connection with Mr. Gaydosik’s appointment as our Chief Financial Officer effective August 11, 2014, the compensation committee determined that Mr. Gaydosik would be entitled to certain termination benefits. If Mr. Gaydosik’s employment with the Company or its successor was terminated within 18 months (subsequently extended to 24 months in his employment agreement discussed below) of the date of occurrence of a change in control, Mr. Gaydosik would have been eligible to receive a cash payment equal to two times his annual base salary and target annual incentive bonus, which would have been $1,050,000, if he was terminated under these circumstance on December 31, 2014. In addition, upon such termination following a change in control, all equity awards that have been granted to Mr. Gaydosik prior to such termination would have been immediately vested on the date of termination and he would have been entitled to continuous medical coverage under COBRA valued at $30,561. If, in the absence of a change in control, Mr. Gaydosik’s employment with the Company was terminated for any reason other than for cause, he would have received severance in the amount equal to one year of his annual base salary and target annual incentive bonus, which at December 31, 2014 would have been $525,000. In addition, all equity awards that have been granted to Mr. Gaydosik prior to such termination would have immediately vested on the date of termination, having a value of $0 as of December 31, 2014, and he would have been entitled to one-year continuation of benefits valued at $19,975 as of December 31, 2014. If Mr. Gaydosik was terminated for cause or voluntarily resigns from his employment with the Company, he would have lost all rights to his unvested equity awards.

As discussed above, on March 13, 2015, we entered into employment agreement with each of Mr. Gaydosik and Mr. Kirtley, effective August 11, 2014 and April 22, 2014, respectively, containing, among other things, certain change in control provisions. For a detailed description of such change in control provisions, see “—Employment Agreement with Our Chief Financial Officer and Chief Operating Officer” above.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who beneficially own more than 10% of a registered class of the Company’s equity securities, to file reports of ownership and changes in ownership with the SEC and to furnish us with copies of the forms they file. To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations of our officers and directors, all Section 16(a) reports for the year ended December 31, 2014 applicable to our officers and directors and such other persons were filed on a timely basis.

Certain Relationships and Related Transactions

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 such 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 of 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, in light of 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.

Proposal to Approve, on an Advisory Basis, the Company’s Executive Compensation

(Item 2 on the Proxy Card)

In accordance with Section 14A of the Exchange Act, our board of directors is providing our stockholders with a non-binding advisory vote on the Company’s executive compensation as reported in this proxy statement, or “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 named executive officers, 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 “Executive Compensation—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, ensures that the Company’s executive compensation arrangements (i) do not incentivize executives to take unnecessary risks, (ii) do not include excessive change in control provisions and (iii) include long-term vesting provisions in the restricted stock grants to encourage executives to focus on long-term performance.

We have determined that our stockholders should cast an advisory vote on the compensation of our named executive officers on an annual basis. Unless this policy changes, the next advisory vote on the compensation of our named executive officers will be at the 2016 annual meeting of stockholders.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THIS PROPOSAL 2.

Proposal to Ratify the Appointment of Our Independent Auditors

(Item 3 on the Proxy Card)

What am I voting on?

You are voting on a proposal to ratify the appointment of Grant Thornton LLP as our independent auditors for fiscal year 2014. The audit committee has appointed Grant Thornton to serve as independent auditors.

What services do the independent auditors provide?

Audit services of Grant Thornton for fiscal 2014 included an audit of our consolidated financial statements and services related to periodic filings made with the SEC. Additionally, Grant Thornton provided certain services related to the consolidated quarterly reports and annual and other periodic reports, registration statements and comfort letters and other services as described below.

How much were the independent auditors paid in 2013 and 2014?

Grant Thornton’s fees for professional services totaled $707,235 for 2013 and $661,833 for 2014. Grant Thornton’s fees for professional services included the following:

Does the audit committee approve the services provided by Grant Thornton?

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 of the fees listed above that we incurred for services rendered by Grant Thornton LLP in fiscal 2013 and 2014 were pre-approved by our audit committee. No non-audit services were provided to us by Grant Thornton in 2013 or 2014.

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

Yes, one or more representatives of Grant Thornton 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.

What vote is required to approve this proposal?

Stockholder ratification of the appointment of our independent auditors is not required by the Company’s 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 of a majority of the votes cast on the proposal. If the appointment of Grant Thornton 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.

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

Grant Thornton has served as our independent auditors since 2005.

What does the board of directors recommend?

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 2015.

We will pay the costs of preparing, printing, assembling and mailing the proxy material used in the solicitation of proxies.

The proposal must be received no later than January 15, 2016.

Stockholders who wish to propose a matter for action at the 2016 Annual Meeting, including with respect to the nomination of directors, but who do not wish to have the proposal or nomination included in the proxy statement, must notify the Company in writing of the information required by the provisions of our by-laws dealing with stockholder proposals.

The board of directors is responsible for selecting and recommending director candidates and will consider nominees recommended by stockholders. If you wish to have the board of directors consider a nominee for director, you must send a written notice to our Corporate Secretary at the address provided above and include the information required by our bylaws and discussed beginning on page 10 of this proxy statement.

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 the Annual Report, along with copies of our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, 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, 14313 North May Avenue, Suite 100, Oklahoma City, Oklahoma 73134 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 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. 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 set of the annual report and proxy statement this year or in future years, follow the instructions described below. Similarly, if you share an address with another Gulfport stockholder and together both of you would like to receive in the future only a single annual report and proxy statement, follow these instructions:

If other matters are properly brought before the meeting, the persons named as your proxies will vote the shares represented by it in accordance with their best judgment. Discretionary authority to vote on other matters is included in the proxy.
