SEC Form DEF 14A filed by Gran Tierra Energy Inc.

TO OUR STOCKHOLDERS,

We invite you to attend the Annual Meeting of Gran Tierra Energy Inc., (“Gran Tierra” or the “Company”) which will be on May 2, 2024, at 10:00 a.m. Mountain Time. This year’s Annual Meeting will be a virtual meeting of stockholders, which will be conducted via live webcast. You will be able to attend the Annual Meeting of Stockholders online, vote your shares electronically and submit your questions during the meeting by visiting https:/web.lumiagm.com/263419250.

The attached Notice of Annual Meeting of Stockholders and Proxy Statement describes the business to be conducted at the Annual Meeting. Whether or not you plan to attend the Annual Meeting of Stockholders, we urge you to submit your vote via the internet or mail.

In 2023, Gran Tierra successfully strengthened its financial position through a significant increase in reserves and production, continued debt reduction, and strategic share buybacks. Our expansion in reserves saw the highest year-end total company reserves in Gran Tierra’s history with Proved—1P totaling 90 MMBOE, the Proved plus Probable—2P totaling 147 MMBOE and Proved, Probable and Possible Reserves totaling 207 MMBOE. These achievements are a testament to our world class assets while also showcasing our commitment to operational excellence. Through Gran Tierra’s successful results from our development drilling, waterflooding programs, field performance and the Suroriente Block Continuation Agreement, Gran Tierra is well-positioned to offer exceptional long-term stakeholder value.

The Company’s achievements wouldn’t have been possible without the efforts made by our teams to conduct operational activities in Colombia and Ecuador in a safe manner. We are building a record of success in a transparent, safe, secure and responsible way and as a result, 2023 was the safest year in the Company’s history. This included more than 16 million hours worked without an incident causing time to be lost, starting in 2022 and sustaining throughout 2023.

Looking forward to 2024, we are excited to restart drilling in our high-impact exploration portfolio, which presents us with opportunities for substantial growth in both Ecuador and Colombia. Gran Tierra will be following up on the encouraging results seen in Ecuador since 2022, and the Company will be undertaking a 238 km² 3D seismic program over the Charapa Block. The Company has started 2024 strong in Colombia with two rigs currently drilling development wells in Acordionero and Costayaco, both of which began their development campaigns in December 2023. Gran Tierra will also be moving forward with its first development drilling program in the Suroriente Block since 2018.

Gran Tierra’s 2024 budget is expected to be fully funded by cash flow, by taking a balanced, returns-focused approach to capital allocation. We plan to focus on four key areas: profitably growing reserves and production in our existing assets, prudently pursuing high impact exploration in our portfolio, fortifying our balance sheet through net debt reduction, and executing share buybacks. One of our focuses for 2024, is to target a net debt to EBITDA ratio of 0.8 to 1.2 times.

Gran Tierra continues to maintain our commitment to our Environmental, Social, and Governance (“ESG”) responsibilities, diligently, executing through our companywide Beyond Compliance Philosophy. Our Beyond Compliance Philosophy means that, wherever there are significant opportunities and benefits to the environment or communities, Gran Tierra works to go beyond what is legally required to protect the environment, provide social benefits, and keep our operations safe because it is the right thing to do.

Our unwavering commitment to fulfill our voluntary Beyond Compliance philosophy includes projects like our flagship conservation program, NaturAmazonas, which we conduct in partnership with non-governmental organization (NGO) Conservation International. This program’s success has set a new Colombian standard for industry-led conservation and as a result we have extended the program another four-years. To date, over 1.6 million trees have been planted. Roughly 4,500 hectares of forested land have been conserved or protected—a space equivalent to 13 times the size of Central Park in New York City.

Gran Tierra’s social investment projects aim to establish sustainable, long-term opportunities that help neighbouring communities create meaningful futures. The Company’s social investment programs have reached over 354,000 beneficiaries in Colombia and Ecuador to date. 2023 was a particularly exciting time for participants from our Hilos de la Tierra program as the Company sponsored three artisans from participating communities of the project to travel to Vancouver, Canada to participate and see their work walk the runway at Vancouver Fashion Week. Hilos de la Tierra is an ongoing project developed by Gran Tierra and is implemented in partnership with the World Women’s Corporation of Colombia (CMMC). The project brought together a creative collaboration with SOCARRÁS, a well-known Colombian fashion designer, and is centered around local artisans from the Putumayo and the Middle Magdalena regions.

With a robust portfolio of assets Gran Tierra is in an excellent position to capitalize on emerging opportunities and deliver value to our stakeholders. We also believe the Company can successfully navigate the current volatile commodity markets with our low base decline, conventional oil reservoirs and our full operational control of capital allocation and timing. As we pursue our operational and financial objectives, we remain committed to continue to foster a culture of safety, innovation, and social responsibility that defines our corporate ethos.

On behalf of our Board of Directors and the Gran Tierra team, I want to thank all our stakeholders for their continued support.

Sincerely,

		/s/ Gary S. Guidry   President and Chief Executive Officer

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the internet. We are sending to our stockholders of record the proxy materials, including this proxy statement and an annual report, or a Notice Regarding the Availability of Proxy Materials (the “Notice”). We intend that our stockholders who hold their stock in “street name” will receive a Notice from their broker, bank or other agent in which they hold the stock in “street name,” unless they have specified otherwise. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice.

We intend to mail the proxy materials and Notice beginning on March 21, 2024 to all stockholders of record entitled to vote at the annual meeting. We expect that the Notice will be sent to stockholders who hold their stock in “street name” on or about this same date.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND 2024 ANNUAL MEETING

Stockholders of Record: Shares Registered in Your Name

If at the close of business on March 6, 2024, your shares were registered directly in your name with Gran Tierra’s transfer agent, Odyssey Trust Company, then you are a stockholder of record. Registered stockholders will receive a proxy form containing the relevant details concerning the business of the meeting, including a control number required to access the virtual annual meeting.

Whether or not you plan to attend the annual meeting, we urge you to fill out and return the proxy or vote by proxy by telephone or on the internet as instructed below to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If at the close of business on March 6, 2024, your shares were held not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice, and/or these proxy materials if you have received them, are being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares electronically or submit questions at the annual meeting unless you request and obtain a valid proxy from your broker or other agent. See “How Do I Vote? - Beneficial Owner: Shares Registered in the Name of Broker or Bank” below for additional information about attending and participating in the annual meeting.

What am I voting on?

There are three matters scheduled for a vote:

What if another matter is properly brought before the annual meeting?

The Board knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the annual meeting or any adjournment or postponement thereof, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

Will I be able to submit questions during the virtual annual meeting?

Stockholders will be able to submit questions through the virtual meeting website. Questions pertinent to meeting matters that comply with the meeting rules of conduct will be answered during the meeting, subject to time constraints. However, we reserve the right to exclude questions that are not pertinent to meeting matters, irrelevant to the business of the Company, derogatory or in bad taste, or relate to pending or threatened litigation, personal grievances or are otherwise inappropriate. Questions that are substantially similar may be grouped and answered once to avoid repetition.

How do I vote?

You may either vote “For” or “Against” or abstain from voting with respect to each nominee to the Board and each of the other matters to be voted on.

Stockholders of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote electronically at the annual meeting, vote by proxy on the internet or vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time. Whether or not you plan to attend the annual meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the annual meeting and vote electronically even if you have already voted by proxy.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a Notice containing voting instructions, or these proxy materials and an annual report and form of proxy, from that organization rather than from Gran Tierra. Simply follow the voting instructions you receive from your broker, bank, or other agent to ensure that your vote is counted. If you have received these proxy materials and voting instructions therein, simply complete and mail the voting instructions to ensure that your vote is counted. Alternatively, if permitted by your broker or bank, you may vote by telephone or on the internet as instructed by your broker, bank or other agent. To vote electronically during the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent and appoint yourself as a proxyholder. Follow the instructions from your broker, bank, or other agent included with these proxy materials, or contact your broker, bank, or other agent to request a proxy form. In addition you must also register your appointment (of your broker or other agent) by emailing [email protected] no later than the voting deadline and provide Odyssey with your name, email, number of shares appointed and name of your broker or other agent where shares are held, so that Odyssey may email the appointee their control number.

A shareholder has the right to appoint a person or entity (who need not be a shareholder) to attend and act for him/her on his/her behalf at the meeting other than the persons named in the enclosed instrument of Proxy. Shareholders who wish to appoint a third party proxyholder to represent them at the online meeting must submit their proxy or voting instruction form (if applicable) prior to registering your proxyholder. Registering your proxyholder is an additional step once you have submitted your proxy or voting instruction form. Failure to register the proxyholder will result in the proxyholder not receiving a Username to participate in the meeting. To register a proxyholder, shareholders MUST email [email protected] and provide Odyssey Trust Company with their proxyholder’s contact information, including email address of appointee, amount of shares appointed and the name of broker or other agent where shares are held, so that Odyssey Trust Company may provide the proxyholder with a control number via email. Requests for registration must be received by Odyssey Trust Company no later than 10:00 a.m. (Mountain Time), on Wednesday, May 1, 2024. You will receive a confirmation of your registration by email after Odyssey Trust Company receives your registration materials.

What if I return a proxy card or otherwise vote but do not make specific choices?

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND 2024 ANNUAL MEETING

Beneficial Owner; Shares Registered in the Name of a Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank or other nominee, and you do not provide the broker or other nominee that holds your shares with voting instructions, your broker or other nominee is not permitted to vote on certain proposals and may elect not to vote on any of the other proposals unless you provide voting instructions. See “What are ‘broker non-votes’ and ‘abstentions’?” below. We encourage you to provide voting instructions to the organization that holds your shares to ensure that your vote is counted on all three proposals.

What happens if I do not vote?

Stockholder of Record; Shares Registered in Your Name

If you are a stockholder of record and do not vote by completing your proxy card, over the internet or at the annual meeting, your shares will not be voted.

Beneficial Owner; Shares Registered in the Name of a Broker or Bank

If you hold your shares in “street name”, you will receive instructions from your broker, bank or other nominee describing how to vote your shares. If you do not instruct your broker, bank or other nominee how to vote your shares, they are not permitted to vote on certain proposals and may elect not to vote on any of the other proposals unless you provide voting instructions. See “What are ‘broker non-votes’ and ‘abstentions’?” below.

Abstentions occur when stockholders are present at the annual meeting but voluntarily abstain on any of the matters upon which the stockholders are voting.

What does it mean if I receive more than one Notice or more than one set of proxy materials?

If you receive more than one Notice or more than one set of proxy materials, your shares may be registered in more than one name or in different accounts.

Your most current proxy card or telephone or internet proxy is the one that is counted and must be received by 10:00 a.m. (Mountain time) on May 1, 2024, to be counted.

Beneficial Owner; Shares Registered in the Name of a Broker or Bank

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

How are votes counted?

Votes will be counted by the inspector of election appointed for the annual meeting, who will separately count, for the proposal to elect directors and the other proposals, votes “For,” “Against,” abstentions and, if applicable, broker non-votes. Broker non-votes have no effect and will not be counted towards the vote total for any proposal.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND 2024 ANNUAL MEETING

What are “broker non-votes” and “abstentions”?

If you are a beneficial owner of shares held in “street name” and do not provide the organization that holds your shares with specific voting instructions, under certain securities exchange rules, the organization that holds your shares is not permitted to vote on certain matters, including the election of directors, and may determine not to vote your shares at all. In order to ensure that your shares are voted on all matters presented at the annual meeting, we encourage you to provide voting instructions in advance of the meeting, regardless of whether you intend to attend the annual meeting. If you do not provide voting instructions and the organization that holds your shares elects to vote your shares on some but not all matters, it will result in a “broker non-vote” for the matters on which the organization does not vote. Abstentions occur when you provide voting instructions but instruct the broker to abstain from voting on a particular matter instead of voting for or against the matter.

How many votes are needed to approve each proposal?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding outstanding shares of Gran Tierra’s capital stock representing at least one-third of the total number of votes that may be cast at the annual meeting are present at the annual meeting or represented by proxy. On the record date, there were 32,316,492 votes that could be cast. Thus, holders of outstanding shares representing at least 10,771,087 votes must be present virtually or represented by proxy at the annual meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote at the annual meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the Chair of the annual meeting or the holders of a majority of shares present at the annual meeting or represented by proxy must adjourn the annual meeting to another date.

How can I find out the results of the voting at the annual meeting?

Preliminary voting results will be announced at the annual meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the annual meeting.

What proxy materials are available on the internet?

The notice of meeting, proxy statement and annual report to stockholders are available to view on Gran Tierra’s website at: https://www.grantierra.com/events/2024-annual-meeting/

See “How do I vote?” above for voting instructions.

Majority Voting Standard

Our Bylaws provide for a majority voting standard for the election of directors in uncontested elections, which is generally defined as an election in which the number of nominees does not exceed the number of directors to be elected at the meeting. Because this is an uncontested election, each director shall be elected by the vote of a majority of the votes cast at a meeting of stockholders at which a quorum is present. A “majority of the votes cast” means that the number of shares voted “For” a director nominee must exceed the number of votes cast “Against” that director nominee. For these purposes, abstentions and broker non-votes will not count as a vote “For” or “Against” a nominee’s election and will have no effect in determining whether a director nominee has received a majority of the votes cast. If an incumbent director is not elected by a majority of the votes cast, the incumbent director must promptly tender his or her or her resignation to the Board. The Nominating and Corporate Governance Committee will make a recommendation to the Board on whether to accept or reject the director’s resignation or whether other action should be taken. The Nominating and Corporate Governance Committee shall recommend, and the Board of Directors’ decision shall be, to accept the resignation absent exceptional circumstances. The Board will act on the Nominating and Corporate Governance Committee’s recommendation within 90 days from the date of the meeting of stockholders and publicly disclose its decision If the Board of Directors determines not to accept a resignation, the public disclosure shall fully state the reasons for such decision. A director who tenders his or her or her resignation after failing to receive a majority of the votes cast will not participate in the Nominating and Corporate Governance Committee’s or the Board’s recommendation or decision or any deliberations related thereto.

PROPOSAL 1: ELECTION OF DIRECTORS

Other Information Regarding Our Directors

Our above-listed directors have neither been convicted in any criminal proceeding during the past ten years nor been parties to any judicial or administrative proceeding during the past ten years that resulted in a judgment, decree or final order enjoining them from future violations of, or prohibiting activities subject to, federal or state securities laws or a finding of any violation of federal or state securities law or commodities law. Similarly, no bankruptcy petitions have been filed by or against any business or property of any of our directors or officers, nor has any bankruptcy petition been filed against a partnership or business association in which these persons were general partners or executive officers.

Skills Matrix

Below is a listing of each director’s key skills, together with a description of those key skills and experience desirable to support the strategic direction of Gran Tierra. Not every director is expected to be skilled in every area, however, we aim for the Board to have a balance of skills and experience. We believe the combination of the skills and qualifications shown below demonstrates how our board is well-positioned to provide effective oversight and strategic advice to our management.

Independence of the Board of Directors

The Company believes in the importance of directors’ independence and follows rules of the NYSE American. As required under the NYSE American listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the Board.

The Board conducts an annual review regarding the independence from the Company’s management of each of its members. After review of all relevant identified transactions or relationships between each director, or any of his or her family members, and Gran Tierra, its senior management and its independent auditors, the Board has affirmatively determined that, other than Mr. Guidry, each of our directors and nominees for director (Peter J. Dey, Evan Hazell, Robert B. Hodgins, Alison M. Redford, Ronald W. Royal, Sondra Scott, David P. Smith and Brooke Wade), are independent directors within the meaning of the applicable NYSE American listing standards. In making this determination, the Board found that none of these directors or nominees for director had a material or other disqualifying relationship with Gran Tierra. Mr. Guidry, Gran Tierra’s President and Chief Executive Officer, is not an independent director by virtue of his employment with Gran Tierra.

PROPOSAL 1: ELECTION OF DIRECTORS

In connection with its assessment of the independence of each non-employee director, the Board of Directors also determined that (i) Messrs. Smith, Hazell, Hodgins and Royal and Ms. Redford, are independent as defined in Section 10A of the Exchange Act and under the standards set forth by the NYSE American applicable to members of the Audit Committee (ii) Messrs. Wade, Dey, Hodgins and Smith, are independent under the standards set forth by the NYSE American applicable to members of the Compensation Committee and (iii) Ms. Redford, Ms. Scott and Messrs. Dey, Hodgins and Wade, are independent under the standards set forth by the NYSE American applicable to members of the Nominating and Corporate Governance Committee.

Stockholder Recommendations and Nominations to the Board

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth on page 22 in the section Considerations in Evaluating Director Nominees based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: Gran Tierra Energy Inc., 500 Centre Street S.E., Calgary, Alberta, Canada T2G 1A6, Attention: Director Nominations. This written recommendation must be delivered at least 120 days prior to the anniversary of the mailing of Gran Tierra’s proxy statement for the last annual meeting of stockholders. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record holder of Gran Tierra’s stock. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Code of Ethics

Gran Tierra has adopted a Code of Business Conduct and Ethics which is available in English and Spanish and applies to every employee, officer and director. Employees, officers and directors are expected to understand the Code and its application to the performance of his or her business responsibilities. The Code of Business Conduct and Ethics is available on the Company’s website at www.grantierra.com/governance. If Gran Tierra makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, Gran Tierra will promptly disclose the nature of the amendment or waiver on its website if required. The Board did not grant any waiver of the Code in favor of a director or executive officer in 2023.

Diversity

Gran Tierra believes in the importance of diversity at all levels throughout the Company. In addition to the traditional concepts of diversity (i.e., gender, culture and geographic region), we believe it is important for the Board to achieve a diversity of knowledge, experience and capabilities that support the Company’s strategic direction. Currently, Gran Tierra does not have a formal policy concerning the diversity of director nominees. However, when considering director candidates, the Board seeks individuals with backgrounds and qualities that, when combined with those of incumbent directors, provide a blend of skills and experience to further enhance the Board’s effectiveness. As part of its annual self-evaluation, the Board assesses whether the directors, both individually and collectively, provide the integrity, experience, judgment, commitment, skills and expertise appropriate for the Company.

Gran Tierra recognizes the benefits of increasing the diversity of its board of directors. The Corporate Governance Guidelines state that as part of the search process for each new director, the Nominating and Corporate Governance Committee will actively seek out women and minority candidates to include in the pool from which Board nominees are chosen.

THE BOARD’S ROLE AND RESPONSIBILITIES

Role of the Board of Directors

The Board is selected by the stockholders to provide oversight of and strategic guidance to senior management. The core responsibility of a Board member is to fulfill his or her or her fiduciary duties of care and loyalty and otherwise to exercise his or her business judgment in the best interests of the Company and its stockholders. The Board has responsibilities to review, approve and monitor fundamental financial and business strategies and major corporate actions, assess major risks facing the Company and consider ways to address those risks, select and oversee management and determine its composition and oversee the establishment and maintenance of processes and conditions to maintain the integrity of the Company. Directors must act with

PROPOSAL 1: ELECTION OF DIRECTORS

integrity and are expected to demonstrate a commitment to the Company, its values and its business and to long-term stockholder value. The duties and responsibilities of the Board and significant issues of corporate governance are set out in the Company’s Corporate Governance Guidelines which are regularly reviewed by the Nominating and Corporate Governance Committee. The guidelines are available on the Company’s website at www.grantierra.com/governance.

Succession Planning

As part of its mandate and annual workplan, the Nominating and Corporate Governance Committee reviews the succession plan for each senior officer, including the President and Chief Executive Officer. The Nominating and Corporate Governance Committee is responsible for ensuring that there is an orderly succession plan for the position of the President and Chief Executive Officer and other members of senior management. To meet this obligation, the President and Chief Executive Officer meets with the Nominating and Corporate Governance Committee and reviews each position, the status of the incumbent, a review of our talent pool and the succession plan for each role.

Board Role in Risk Oversight

Further, the Board has delegated the primary responsibility to oversee risks from cybersecurity threats to the Audit Committee. The Board and the Audit Committee regularly review the measures implemented by the Company to identify and mitigate data protection and cybersecurity risks. The Board and Audit Committee are updated on a quarterly basis by Vice President, Corporate Services on the Company’s internal information technology (“IT”) security testing, any unauthorized attempts to access the Company’s network, any significant developments in cybersecurity risks and threats, and updates on the Company’s policies and procedures for protecting the Company’s data. The Company has protocols, as discussed in the 2023 Annual Report on Form 10-K, by which certain cybersecurity concerns, incidents and threats are escalated within the Company and, where appropriate, reported in a timely manner to the Board and Audit Committee.

PROPOSAL 1: ELECTION OF DIRECTORS

Communications with the Board of Directors

Stockholders are encouraged to communicate by voting on the items in the proxy statement, by attending the annual meeting, by participating in the Company’s quarterly investor calls and by contacting us by mail or email. Security holders and other interested parties wishing to communicate with the Board or an individual director may send a written communication addressed to the Corporate Secretary of the Company at 500 Centre Street S.E., Calgary, Alberta, Canada T2G 1A6, Attention: Corporate Secretary. Communications also may be sent by e-mail to the following address [email protected]. Further information about Gran Tierra’s Security Holder Communication Process is available on Gran Tierra’s website at www.grantierra.com/governance.

BOARD STRUCTURE AND PROCESSES

Board Leadership Structure

The positions of Board Chair and the Chief Executive Officer of the Company are held by two individuals. We believe separation of the roles of Board Chair and Chief Executive Officer helps preserve our Board’s independence and objectivity and provides an appropriate division of labor between our Board Chair and Chief Executive Officer. The Board believes that the current board leadership structure, coupled with a strong emphasis on board independence, effectively allocates authority, responsibility, and oversight between management and the independent members of our Board. Robert B. Hodgins currently serves as non-executive Board Chair and as a non-executive and independent director. The Board Chair presides over meetings of the Board, presides over meetings of stockholders, consults and advises the Board and its committees on the business and affairs of the Company, and performs additional duties as the Board may otherwise determine and delegate.

Board Effectiveness and Director Assessment

The Board performs an annual self-assessment, led by the Chair of the Nominating and Corporate Governance Committee, to evaluate its effectiveness in fulfilling its obligations. Directors complete a written questionnaire covering performance of the Board and its committees. The Chair of the Nominating and Corporate Governance Committee then interviews each director to obtain an assessment of the effectiveness of the Board and committees, as well as director performance and Board dynamics, summarizes these individual assessments for discussion with the Board and committees, and then leads a discussion with the Nominating and Corporate Governance Committee and the Board.

Considerations in Evaluating Director Nominees

The Nominating and Corporate Governance Committee is responsible for identifying and recruiting new candidates for nomination to the Board. The Nominating and Corporate Governance Committee considers recommendations for nominees for directorships submitted by stockholders. The Company will evaluate director nominees proposed by stockholders on the same basis as recommendations received from any other source. Please see “Stockholder Recommendations and Nominations to the Board” in this Proxy Statement for procedures to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board.

In developing recommendations for the Board, the Nominating and Corporate Governance Committee uses a variety of methods for identifying and evaluating nominees for directors. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of Gran Tierra and the long-term interests of stockholders. Some of the qualifications that the Nominating and Corporate Governance Committee considers include:

PROPOSAL 1: ELECTION OF DIRECTORS

In conducting this assessment, the Nominating and Corporate Governance Committee considers diversity, age, skills, and such other factors as it deems appropriate given the current needs of the Board and Gran Tierra, to maintain a balance of knowledge, experience and capability. In February 2021, the Board updated its Corporate Governance Guidelines to state that as part of the search process for each new director, the Nominating and Corporate Governance Committee will actively seek out women and minority candidates to include in the pool from which Board nominees are chosen.

To identify, recruit and evaluate qualified candidates for the Board, the Nominating and Corporate Governance Committee may use the services of professional search firms. In some cases, nominees have been individuals known to Board members or others through business or other relationships.

Director Tenure

Gran Tierra does not have a retirement policy or term limit for directors. We review our Board composition annually to ensure our Board has the right skills to ensure the Company’s long-term success.

Orientation and Education

The purpose of the Director Orientation and Education Program is to ensure there is an orientation program for new directors and an ongoing education program for existing directors. The program includes materials and resources that will inform and educate directors on the Company’s corporate governance framework, its business, operations and current issues and strategies. New directors attend an orientation session at which senior management review the Company’s business, strategic plans, its significant financial, accounting and risk management issues, its compliance programs, its Code of Business Conduct and Ethics, its principal officers, and its internal and independent auditors. New directors are also provided with a copy of the Company’s director’s manual which includes the Board and Committee mandates, corporate governance guidelines and other company policies.

Each director is expected to maintain the necessary level of expertise to perform his or her responsibilities as a director. Continuing education is provided through a number of methods, including an annual dedicated strategy session, periodic field trips, presentations from senior management, employees, and outside experts to the Board and its Committees on topics of interest and developing issues, as well as the ongoing distribution of relevant information. These presentations, meetings and discussions serve to increase the Board’s knowledge of the Company and its business, and assist the Board in the execution of its duties. During 2023, the Board attended a number of sessions relevant to our business and the regulatory environment presented by senior executives of the Company and our legal counsel.

All of our directors are members of the Institute of Corporate Directors (ICD) and the National Association of Corporate Directors (NACD), which provide continuing education for directors through publications, seminars and conferences.

PROPOSAL 1: ELECTION OF DIRECTORS

Director Meetings and Attendance

Directors are expected to attend, in person or by telephone, all meetings of the Board and all meetings of each committee of which they are a member. During 2023, the Board held ten meetings, the Audit Committee held four meetings, the Compensation Committee held four meetings, the Health, Safety and Environment Committee held four meetings, the Nominating and Corporate Governance Committee held three meetings and the Reserves Committee held two meetings. No member of the Board attended fewer than 75% of the aggregate of the total number of meetings of the Board (held during the period for which he or she was a director) and the total number of meetings held by all committees of the Board on which such director served (held during the period that such director served). Directors are also expected to attend the Company’s annual meeting of stockholders and all of the Company’s directors attended the 2023 annual meeting which was held by webcast.

Executive Sessions

As part of each regularly scheduled Board meeting, the independent directors meet without our management team. The Board Chair leads such discussions.

PROPOSAL 1: ELECTION OF DIRECTORS

INFORMATION REGARDING COMMITTEES OF THE BOARD OF DIRECTORS

The Board has five standing committees: an Audit Committee, a Compensation Committee, a Health, Safety and Environment Committee, a Nominating and Corporate Governance Committee, and a Reserves Committee. The composition and responsibilities are described below. Members serve on these committees until their resignation or until otherwise determined by the Board.

The committees regularly report their activities and actions to the full Board, generally at the next Board meeting following the committee meeting. Each of the committees operates under a charter approved by the Board. Current copies of the charters of the committees are available on the Company’s website at www.grantierra.com/governance.

PROPOSAL 1: ELECTION OF DIRECTORS

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation Committee has at any time been an officer or employee of Gran Tierra. No member of the Board or of the Compensation Committee served as an executive officer of another entity that had one or more of our executive officers serving as a member of that entity’s board or compensation committee.

PROPOSAL 1: ELECTION OF DIRECTORS

DIRECTOR COMPENSATION

The objective of Gran Tierra’s compensation program for non-executive directors is to attract and retain directors of a quality and nature that will enhance our long-term sustainable profitability and growth. Director compensation is intended to provide an appropriate level of remuneration considering the experience, responsibilities, time commitment and accountability of their roles. The Company intends for director compensation to be competitive with our peer companies. Any director who is also an employee of the Company does not receive additional compensation for serving as a director.

Non-executive director compensation is reviewed and recommended annually by the Nominating and Corporate Governance Committee to verify that it is reasonable in light of the time required from directors and aligns directors’ interests with those of our stockholders.

There were no changes to the director compensation program in 2023.

The director compensation structure for non-executive directors as of January 1, 2023 was as follows:

The cash retainer portion of the director’s fees can be taken in the form of cash, Restricted Stock Units (“RSUs”), Deferred Stock Units (“DSUs” and each a “DSU”) or any combination thereof, as elected by each non-employee director. The equity portion must be taken in the form of equity until the stock ownership guideline is achieved. A maximum of 25% of the equity retainer can be taken as stock options which vest immediately and expire after five years. DSUs vest immediately but are not paid out until the director ceases to be a director of Gran Tierra and RSUs vest and are paid out after three years. The number of DSUs, RSUs or stock options credited to each director is calculated by dividing the dollar value of the portion of the director’s retainer to be paid in the form of DSUs, RSUs or stock options by the fair market value of Gran Tierra’s stock on the day of determination. A travel fee is paid to each director for travel over three hours to a Board meeting.

Directors’ DSU Plan

The DSU plan allows directors to defer receipt of their cash fees and invest such deferred amounts in notional shares of Gran Tierra. Directors who have elected to be paid all or a portion of the annual retainer in DSUs receive their awards on a quarterly basis effective the first day of each quarter. The number of DSUs credited to each director is calculated by dividing the dollar value of the portion of the director’s retainer that he or she has elected to be paid in the form of DSUs by the fair market value of a common share of Gran Tierra on the day of determination. The DSUs vest immediately but are not paid out until the director ceases to be a director of Gran Tierra. The Board has discretion to settle the DSUs in common shares or in a cash amount equal to the market value of common shares at the time of settlement. DSUs are not shares and do not carry voting rights. DSUs received by directors in lieu of cash compensation and held by them represent an at-risk investment in Gran Tierra. The value of DSUs is based on the value of the common shares of Gran Tierra, and therefore is not guaranteed.

PROPOSAL 1: ELECTION OF DIRECTORS

Director Compensation Table

The following table shows for the fiscal year ended December 31, 2023, the value of amounts paid or granted to all non-employee directors of Gran Tierra.

PROPOSAL 1: ELECTION OF DIRECTORS

Director Share Ownership Requirements

Gran Tierra maintains a policy requiring directors to acquire common shares and/or DSUs equivalent in value to three times their annual cash retainer within five years from the date of first election to the Board. The shareholdings of each non-executive director are valued using either the closing price of our shares on December 31 each year or the value at the time they were acquired, whichever is greater. The following table sets out the non-executive director share ownership requirements for 2023.

All of the Directors have met their share ownership requirements as of December 31, 2023.

Prohibition on Hedging and Pledging

We maintain a policy for securities transactions applicable to all employees including officers, directors, and other members of management of the Company which prohibits engaging in short sales, transactions in put or call options, hedging transactions or other inherently speculative transactions with respect to our stock at any time. The policy also prohibits margining or pledging Company securities. In addition, our Insider Trading Policy, among other things, prohibits our officers, directors and employees from trading during quarterly and special blackout periods.

Directors’ and Officers’ Insurance

We maintain an insurance policy for directors’ and officers’ liability which provides coverage for costs incurred to defend and settle claims against directors or officers up to an annual limit of $55 million. The cost of coverage for 2023-2024 is approximately $706,100. Directors and officers do not pay any portion of the premiums. No claims were made or became payable in 2023.

Audit-Related Matters

PROPOSAL 2: RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The Audit Committee of the Board believes that the continued retention of KPMG LLP to serve as the Company’s independent registered public accounting firm is in the best interests of the Company and its stockholders and has further directed that management submit the selection of KPMG LLP for ratification by the stockholders at the annual meeting.

Neither Gran Tierra’s Bylaws nor other governing documents or law require stockholder ratification of the selection of KPMG LLP as Gran Tierra’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of KPMG LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of Gran Tierra and its stockholders.

Representatives of KPMG LLP are expected to be present at the annual meeting and will have an opportunity to make a statement and respond to appropriate questions from stockholders raised at the meeting.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” OF PROPOSAL 2.

Audit Committee Report

The Audit Committee is a committee of the Board comprised solely of independent directors as required by the listing standards of the NYSE American and rules of the SEC. In accordance with the written Audit Committee Charter, the Audit Committee assists the Board in fulfilling its responsibility for oversight of the quality and integrity of the accounting, auditing and financial reporting practices of the Company.

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2023, with management of Gran Tierra and the independent registered public accounting firm. Management has the responsibility for the preparation of the Company’s financial statements, and the independent registered public accounting firm has the responsibility for the audit of those statements. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by applicable standards of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee has recommended to the Board that the audited financial statements be included in Gran Tierra’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for filing with the Securities and Exchange Commission.

PROPOSAL 2: RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

Principal Accountant Fees and Services

The Audit Committee is responsible for the audit fee negotiations associated with the retention of our independent registered public accounting firm. For the fiscal years ended December 31, 2023, and December 31, 2022, KPMG LLP served as our independent registered public accounting firm. The aggregate fees paid by the Company to KPMG LLP for professional services rendered in Gran Tierra’s last two fiscal years are as follows. In determining the independence of KPMG LLP, the Audit Committee considered whether the provision of non-audit services is compatible with maintaining KPMG LLP’s independence.

Audit Fees

Audit Fees are primarily for the annual audit of the Company’s consolidated financial statements included in the Form 10-K, including the audit of the effectiveness of the Company’s internal controls over financial reporting, the reviews of the Company’s financial statements included in the Forms 10-Qs, statutory audits, and other procedures required to be performed by the independent auditor to be able to form an opinion on the Company’s consolidated financial statements.

Tax Fees

Tax fees were for tax compliance, tax advice and tax planning.

All Other Fees

All Other Fees related to products and services provided by KPMG LLP other than those described as “Audit fees” and “Tax fees” are primarily related to the Company’s debt restructuring activities in 2023.

All services described above were approved by the Audit Committee.

Pre-Approval Policies and Procedures

Our Audit Committee is responsible for the engagement of the independent auditors and for approving, in advance, all auditing services and permitted non-audit services to be provided by the independent auditors. The Audit Committee maintains a policy for the engagement of independent auditors that is intended to maintain the independence from Gran Tierra of the independent auditors. In adopting this policy, our Audit Committee considered the various services that independent auditors have historically performed or may be needed to perform in the future for Gran Tierra. Under this policy:

In its review of all non-audit service fees, our Audit Committee considers, among other things, the possible effect of these services on the independence of our independent auditors. Relevant considerations include, but are not limited to, whether the services are prohibited pursuant to SEC rules, whether the auditors are best positioned to provide the services, and the percentage of total services the non-audit services will comprise.

PROPOSAL 2: RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

Any approval required under this policy must be given by our Audit Committee or by the chairperson of the Audit Committee in office at the time, provided that any pre-approval decisions made by the chairperson must be reported to the Audit Committee at its next scheduled meeting. Gran Tierra’s Audit Committee will not delegate its responsibilities to approve services performed by the independent auditors to any member of management. All services rendered by KPMG LLP in 2023 were subject to our pre-approval policy.

Proposal 3: Advisory Vote to Approve Named Executive Officer Compensation

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Section 14A of the Exchange Act, Gran Tierra’s stockholders are entitled to vote to approve, on an advisory basis, the compensation of Gran Tierra’s named executive officers as disclosed in this proxy statement in accordance with SEC rules. This vote is not intended to address any specific item of compensation, but rather the overall compensation of Gran Tierra’s named executive officers for the last completed fiscal year and the philosophy, policies and practices described in this proxy statement.

The compensation of Gran Tierra’s named executive officers subject to the vote is disclosed in the Executive Compensation section, including the compensation tables and the narrative disclosure related to such compensation tables contained in this proxy statement. As discussed in those disclosures, Gran Tierra believes that its compensation policies and decisions are consistent with current market practices and are focused on pay-for-performance principles that strongly align the interests of our named executive officers with those of our stockholders. Compensation of Gran Tierra’s named executive officers is designed to enable Gran Tierra to attract and retain talented and experienced executives to lead Gran Tierra successfully in a competitive environment.

Accordingly, the Board is asking the stockholders to indicate their support for the compensation of Gran Tierra’s named executive officers as described in this proxy statement in pages 37 to 51 by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to Gran Tierra’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion related to such compensation tables in this proxy statement, is hereby APPROVED.”

Because the vote is advisory, it is not binding on the Board or Gran Tierra. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements. The next non-binding advisory vote on the compensation of named executive officers is expected to occur in 2025.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” PROPOSAL 3.
