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, 2025, 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/208908912.

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.

2024 was another pivotal year for Gran Tierra, defined by significant exploration success in Ecuador, continued operational excellence in Colombia, and an exciting new country entry into Canada. Our strategy of expanding into proven hydrocarbon basins with existing infrastructure has strengthened our asset base, allowing us to capitalize on high-return development opportunities. In 2024, Gran Tierra demonstrated its confidence in the Company’s future prospects by repurchasing 6.7% of our outstanding shares through our normal course issuer bid program—demonstrating our dedication to long-term shareholder value creation. With a current 1P before tax net asset value of $35.23 per share, share buybacks remain a strategic and efficient way to return capital to our shareholders, while reinforcing our commitment to long-term value creation.

Gran Tierra continues to build a diversified, high-quality portfolio across multiple jurisdictions, positioning us to capitalize on opportunities in both conventional and unconventional hydrocarbon basins. Our management team has a strong track record of executing value-enhancing acquisitions and creating long-term value for our stockholders. In 2024, we once again exceeded 100% reserve replacement on a proved basis, with exceptional reserve replacement rates of 702% (1P), 1,249% (2P), and 1,500% (3P), driven by our exploration success in Colombia and Ecuador and our strategic entry into Canada.

Last year was Gran Tierra Energy’s safest year on record. The Company has now accumulated a total of 27.8 million person-hours without a Lost Time Injury (LTI). In 2024, its Total Recordable Incident Frequency (TRIF) was 0.03, placing Gran Tierra in the top quartile for safety performance across its operating regions. We remain committed to continuously reinforcing this culture to ensure our operations remain amongst the safest in our industry.

Building upon our achievements in 2024, we are excited about our 2025 development and exploration program, which is expected to be fully funded by cash flow. The Company generated net cash provided by operating activities of $239.3 million, an increase of 5% from 2023 and realized 2024 Net Income of $3 Million ($0.10 per share, basic) and 2024 Adjusted EBITDA of $367 Million. Our approach remains focused on portfolio longevity and maximizing returns, with a capital allocation strategy which emphasizes profitable reserve and production growth across our Canadian, Colombian and Ecuadorian assets.

We are excited about the prospects of our 2025 exploration initiatives in Ecuador and Colombia, where we are set to drill between 6 to 8 high-impact exploration wells. These prospects have the potential to be significant catalysts in our commitment to unlock new reserves and drive sustainable growth. We are also pleased to be drilling prolific wells in the Montney and appraisal in the Clearwater and Central Alberta. Gran Tierra has drilled 5 new wells in the Clearwater at East Dawson and Walrus. This program has confirmed the quality of our acreage in the Clearwater play. With our expansion into Canada, approximately 20% of our production, 23% of our 1P reserves, and 26% of our 2P reserves now include conventional and shale gas assets, providing greater resilience across commodity cycles.

Gran Tierra prioritizes achieving its objectives through adherence to guiding principles, including compliance with all relevant regulatory frameworks. The company also undertakes initiatives beyond these requirements to further promote safety, protect the environment, support communities, respect Human Rights, and contribute to local stability.

Our strong commitment to fulfilling our voluntary Beyond Compliance philosophy includes projects like our flagship conservation program, NaturAmazonas, which was founded by Gran Tierra Energy and Conservation International in 2017. The high-quality cocoa produced through this program gained international recognition, leading to a commercial agreement with KAOKA—one of the world’s largest buyers of organic cocoa—to export 12.5 tons of organic, deforestation-free cocoa. This achievement opens new markets and income opportunities for producers in the Putumayo region. Across all of Gran Tierra’s environmental initiatives, the Company has planted over 1.9 million trees and has conserved, preserved, or reforested more than 5,400 hectares of land to date.

Looking ahead, we remain committed to operational and financial excellence, which is matched by our dedication to the well-being of our employees, the communities and environments in which we operate. We remain focused on responsible growth, safety, and sustainability as we continue to deliver long-term value to all our stakeholders, local communities and the environment.

On behalf of the Board of Directors and our leadership team, thank you for your continued support and confidence in Gran Tierra Energy. We look forward to discussing our achievements and future plans with you at the 2025 Annual General Meeting.

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

100% independent Committee members

Executive Compensation Highlights

Our compensation philosophy and programs are based on the following core principles:

•

attract and retain highly capable individuals and offer competitive compensation opportunities,

•

pay for performance, and

•

align the interests of management with our stockholders.

Our equity compensation program is designed to be aligned with the interests of our stockholders and focuses on

pay-for-performance:

•

The majority of 2024 executive compensation is considered to be “at risk” because its value is based on specific performance criteria and/or stock price appreciation and payout is not guaranteed.

•

In 2024, 80% of the value of equity awards granted to the Named Executive Officers (“NEOs”) consisted of performance share units (“PSUs”) and 20% consisted of restricted stock units (“RSUs”).

•

The target for total compensation for each of our NEOs is approximately the 50

percentile as compared to the Company’s compensation peer group.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND 2025 ANNUAL MEETING

Stockholders of Record: Shares Registered in Your Name

If at the close of business on March 6, 2025, 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, 2025, 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:

1.	Election of nine nominees named in the proxy statement to serve on the Board until the next annual meeting and until their respective successors are duly elected and qualified;

3.	Approval, on an advisory basis, of the compensation of Gran Tierra’s named executive officers, as disclosed in this proxy statement.

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 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. Please follow the voting instructions on the Notices or the instructions on the proxy cards in the proxy materials to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Stockholder of Record; Shares Registered in Your Name

Yes. You can revoke your proxy at any time before the final vote at the annual meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

•

You may submit another properly completed proxy card with a later date, or vote again on the internet;

•

You may send a timely written notice that you are revoking your proxy to Gran Tierra’s Corporate Secretary at 500 Centre Street S.E., Calgary, Alberta, Canada T2G 1A6; or

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND 2025 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?

•

Proposal No. 1, the election of directors: 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

•

Proposal No. 2, the ratification of the appointment of KPMG LLP as Gran Tierra’s independent registered public accounting firm for 2025, will be approved if it receives the affirmative vote of shares representing a majority of the votes present or represented by proxy at the meeting and entitled to vote on the matter. Abstentions will have the same effect as a vote “Against”. Broker

non-votes,

if any, will have no effect.

•

Proposal No. 3, the advisory vote to approve named executive officer compensation, as disclosed in this proxy statement, will be approved if it receives the affirmative vote of shares representing a majority of the votes present or represented by proxy at the meeting and entitled to vote on the matter. Abstentions will have the same effect as a vote “Against” Broker

non-votes,

if any, will have no effect.

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 35,888,773 votes that could be cast. Thus, holders of outstanding shares representing at least 11,962,805 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/2025-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.

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

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

Independence of the Board of Directors

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.

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.

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 2024.

Diversity

Gran Tierra believes in the importance of diversity at all levels throughout the Company. We believe it is important for the Board to achieve a diversity of knowledge, experience, capabilities and viewpoints 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 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



20		Gran Tierra Energy 2025 Proxy Statement

PROPOSAL 1: ELECTION OF DIRECTORS

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

The full Board is entrusted with the responsibility for overseeing the significant risks to which our business is exposed and ensuring there are processes in place to effectively identify, monitor and manage them. A significant risk is one that, if it were to occur, could materially impact our ability to meet or support our business objectives. The Board delegates responsibility for the execution of certain elements of risk oversight to the committees to ensure appropriate expertise, attention and diligence. The committees oversee the relevant risk areas and report to the Board regularly. Each committee operates according to a Board-approved written mandate outlining its duties and responsibilities. They also oversee the procedures and programs put in place by management to mitigate the risks and the allocation of adequate resources to address the risks. Management is responsible for ensuring that the Board and its committees are kept well informed of changing risks. The risk oversight responsibilities of the committees include the following:

•

The Audit Committee

is responsible for overseeing the integrity of the Company’s financial statements, the independent auditor’s qualifications and independence, the performance of the Company’s internal audit function and independent auditor, compliance with legal and regulatory requirements, major financial and information technology risk exposures and the Company’s accounting and financing reporting processes.

The Compensation Committee

is responsible for oversight of compensation-related risks, including reviewing management’s assessment of risks related to employee compensation programs.

The Health, Safety and Environment Committee

assists in overseeing the development, monitoring and effective implementation of systems, programs and initiatives to promote the management of health, safety and security at Gran Tierra and to address environmental, safety and operational risks.

The Nominating and Corporate Governance Committee

assists in overseeing governance related risks, including regulatory, reputation and other risks.

The Reserves Committee

assists in overseeing the risks related to the Company’s estimates of proved reserves of oil and natural gas.

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 2024 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.

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 Secretary of the Company at 500 Centre Street S.E., Calgary, Alberta, Canada T2G 1A6, Attention: Secretary.

PROPOSAL 1: ELECTION OF DIRECTORS

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 Nominations 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 Nominations 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:



Independence (as per applicable NYSE American listing standards and applicable SEC rules and regulations)	Relevant Industry Experience	Excellence in His or Her Field

Potential Conflicts
of Interest and
Other Commitments

Board Experience

Ethics

Diversity of
Experience



22		Gran Tierra Energy 2025 Proxy Statement

PROPOSAL 1: ELECTION OF DIRECTORS

In conducting this assessment, the Nominating and Corporate Governance Committee considers viewpoint 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.

The Nominating and Corporate Governance Committee believes that candidates should have certain minimum qualifications including:

•

the highest personal and professional ethics and integrity

•

skills that are complementary to those of the existing Board

•

financial literacy

•

sound business judgment

•

commitment to represent the long-term interests of Gran Tierra’s stockholders

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 2024, 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. During 2024, a number of our directors attended seminars provided through ICD and NACD.

Gran Tierra Energy 2025 Proxy Statement		27

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.

In December 2024, the Nominating and Corporate Governance Committee approved certain changes to the compensation structure of the

non-executive

directors as outlined below.

The director compensation structure for

non-executive

directors as of January 1, 2024 was as follows:



	2024 Annual Cash Retainer and Travel Fees (1)		2024 Annual Equity Retainer (DSUs, RSUs, Stock Options) (1)

Board Chair	$	64,282	$	132,039

Board Member	$	38,222	$	111,538

Audit Committee Chair	$	31,272

Other Committee Chairs	$	20,848

Committee Members	$	10,424

Travel Fee (over three hours) per meeting	$	1,042

(1)	All compensation to non-employee directors is paid in Canadian dollars and converted into U.S. dollars for the purposes of the above table. The exchange rate at December 31, 2024 was used for this purpose and was one US dollar to Canadian $1.4390.

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 or RSUs credited to each director is calculated by utilizing a previous

year-end

ten (10) day volume weighted average pricing mechanism 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 January 1 of each year. The number of DSUs or RSUs 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 previous

year-end

ten (10) day volume weighted average pricing 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.

Amounts reported in this column represent cash and committee retainers, whether received currently or deferred in DSUs. Cash fees that were deferred by an election of a director and received in the form of DSUs (Stock Awards) are reported in the table below. All compensation to

non-employee

directors is paid in Canadian dollars and converted into U.S. dollars for the purposes of the above table. For 2024 compensation amounts, the exchange rate at December 31, 2024 of one U.S. dollar to Canadian $1.4390 is used.

Amounts in the Stock Awards column reflect the aggregate grant date fair value of DSUs computed in accordance with GAAP. The Company currently intends to settle the DSUs outstanding as of December 31, 2024 in cash, and, therefore, DSUs are accounted for as liability instruments. The amounts in this column include DSUs which were issued as a result of an election by the directors to be paid a portion of their retainer in the form of DSUs. The value ultimately realized by each director may or may not be equal to this determined value. As of December 31, 2024, each of the

non-employee

directors had aggregate outstanding DSUs as follows, all of which were fully vested: Mr. Dey – 136,971; Mr. Hazell – 131,914; Mr. Hodgins – 138,173; Ms. Redford – 50,376; Mr. Royal – 159,970; Ms. Scott – 75,579; Mr. Smith – 45,438; and Mr. Wade – 166,343. None of the directors hold RSUs.

(3)

Amounts in the Options Awards column reflect the aggregate grant date fair value computed in accordance with ASC 718. Assumptions made in the valuation of stock options granted are discussed in Note 8 to Gran Tierra’s 2024 Consolidated Financial Statements, which can be found in Item 8 of the Form

10-K

filed with the SEC on February 24, 2025.

(4)	Amounts reported in this column represent fees paid for travel to or from a meeting of the Board in excess of three hours per meeting.

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 2024.



		Ownership Requirement 2024

Board Chair		3x annual Board cash retainer fees in Common Shares and DSUs 3 X $64,282 = $192,846

Non-Executive Directors		3x annual Board cash retainer fees in Common Shares and DSUs 3 x $38,222 = $114,665

All of the Directors have met their share ownership requirements as of December 31, 2024.

Insider Trading Policy; Prohibition on Hedging and Pledging

We have adopted an insider trading policy (the “Insider Trading Policy”) and procedures governing the purchase, sale, and other transactions in our Company’s securities by the Company’s directors, officers, and employees, and other covered persons that we believe are reasonably designed to promote compliance with insider trading laws, rules, and regulations and NYSE listing standards.

The Insider Trading Policy 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 $60 million. The cost of coverage for 2025 is approximately $485,798. Directors and officers do not pay any portion of the premiums. No claims were made or became payable in 2024.

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, 2024, 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, 2024, 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, 2024, and December 31, 2023, 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.



	Year Ended December 31,

(Thousands of U.S. Dollars)	2024		2023

Audit Fees		1,539		1,373

Tax Fees (1)		152		203

All Other Fees		532		1,159

Total Fees		2,223		2,734

(1)	Included in Tax Fees are $106K fees related to tax compliance for 2024

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 and business development activities in 2024.

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:

•

the Audit Committee approves the performance by the independent auditors of audit or permitted

non-audit

services, subject to restrictions in certain cases, based on the Audit Committee’s determination that such services would not be likely to impair the independence of the independent auditors from Gran Tierra;

•

Gran Tierra’s management must obtain the specific prior approval of our Audit Committee for each engagement of the independent auditors to perform any audit or permitted

non-audit

services; and

•

the performance by the independent auditors of certain types of services (bookkeeping or other services related to the accounting records or financial statements of Gran Tierra; financial information systems design and implementation; appraisal or valuation services, fairness opinions or

contribution-in-kind

reports; actuarial services; internal audit outsourcing services; management functions or human resources; broker or dealer, or investment adviser or investment banking services; legal services and expert services unrelated to the audit; and any other service that the applicable federal oversight regulatory authority determines, by regulation, is impermissible) is prohibited due to the likelihood that their independence would be impaired.

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 2024 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 45 to 72 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 2026.

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

EXECUTIVE COMPENSATION

The following discussion provides details regarding our executive compensation program and 2024 compensation arrangements for each of our Named Executive Officers (“NEOs”) who, for 2024 were:



Name		Title at December 31, 2024

Gary S. Guidry		President and Chief Executive Officer

Ryan Ellson		Chief Financial Officer and Executive Vice President, Finance

Sebastien Morin		Chief Operating Officer

Phillip D. Abraham		Executive Vice President, Legal and Land

Jim Evans		Executive Vice President, Corporate Services

Philosophy and Objectives of our Executive Compensation Program

Our compensation philosophy is to provide an attractive, flexible, and market-based total compensation program that is tied to performance and aligns the interests of our NEOs with those of our stockholders. The Company’s objective is to recruit and retain the caliber of executive officers and other key employees necessary to deliver sustained high performance to our stockholders as well as economic growth and respect for the communities in which we have a strong presence. Our compensation philosophy also serves as a means of communicating our goals and standards of conduct and performance, and for motivating and rewarding our NEOs in relation to their achievements. Our compensation philosophy includes the principles described below:

•

Hire and retain top caliber and highly capable executives

: Executive officers should have a total compensation package that is market competitive and permits us to hire and retain high-caliber individuals at all levels.

•

Pay for performance

: A significant portion of the annual compensation opportunity for our executive officers should be directly tied to the achievement of key operational and financial measures aligned with our strategy, relative TSR and our share price performance. Directly linking pay with our performance is essential to delivering long-term value to our stockholders.

•

Create Stockholder Alignment

: A significant portion of compensation should be variable (at risk) and equity-based. Executives are also required to meet significant share-ownership guidelines.



Gran Tierra Energy 2025 Proxy Statement		37

PROPOSAL 3: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

Responsibilities for Executive Compensation

Compensation decisions for our executive officers are made by the Compensation Committee, with input from our independent compensation consultants as well as from our Chief Executive Officer. The specific roles are summarized below:



Compensation Committee		• Oversees compensation policies, plans and programs, reviews and determines the compensation to be paid to our executive officers and directors annually. • Oversees our annual and long-term incentive plans and programs and periodically assesses our non-employee director compensation program. • Approves the goals of our Chief Executive Officer, evaluates our Chief Executive Officer’s performance in light of those goals and objectives and recommends to the Board the approval of the Chief Executive Officer’s annual compensation. • Together with our Chief Executive Officer, reviews and approves the corporate performance goals and objectives of our other NEOs and recommends to the Board the approval of the annual compensation package for the other NEOs. • Holds executive sessions with no management present.

Board		• Reviews Chief Executive Officer’s performance. • Approves Chief Executive Officer and NEO compensation.

Independent Compensation Consultants		• Provides the Compensation Committee with independent advice concerning the types and levels of compensation to be paid to our Chief Executive Officer and the other NEOs. • Provides market compensation data (e.g., industry compensation surveys and benchmarking data) on base salary, annual incentives and long-term incentives and industry trends.

Chief Executive Officer		• Reviews performance of other NEOs with the Compensation Committee. • Makes recommendations on base salary, annual bonus and long-term incentives awards for the other NEOs.

The Board and the Compensation Committee hold regular executive sessions at the end of each meeting with no representatives of the management team present. Our Chief Executive Officer does not attend any portion of the Compensation Committee or Board meeting during which his compensation is deliberated or approved. Except as expressly described in the table above, our Chief Executive Officer does not play any role with respect to any matter affecting his own compensation.

The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer. From time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. Under the charter, the Compensation Committee has the authority to obtain, at the expense of Gran Tierra, advice and assistance from compensation consultants, internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any advisers engaged for the purpose of advising the Compensation Committee and may amend the engagement with or terminate any such advisor as it deems necessary or appropriate.

The Compensation Committee and the Board make their compensation decisions for the upcoming year, and review performance for the prior year, generally in the first quarter of the year. Annual bonuses in respect of 2024 performance were recommended by the Compensation Committee and approved by the Board in February 2025.

Assessment of Company Performance

The Compensation Committee uses Company performance measures to establish total compensation ranges relative to our performance and the performance of our comparator groups as outlined on the following page. In addition, the Compensation Committee establishes specific performance measures that determine payouts under cash and equity-based incentive programs.



38		Gran Tierra Energy 2025 Proxy Statement

PROPOSAL 3: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

Role of the Independent Compensation Consultant

When making determinations regarding executive compensation, the Compensation Committee considers advice from external advisors and third-party compensation surveys as well as the advice of Compensation Committee members and other members of the Board based on their knowledge and experience to set competitive, results driven levels of salary and other compensation.

The Compensation Committee may, in its sole discretion, retain or obtain the advice of independent compensation consultants or other external advisors and is directly responsible for the appointment, compensation arrangements and oversight of the work of any such person. The retention of independent compensation consultants and scope of services provided by them are assessed on an annual basis.

The Compensation Committee may select a compensation consultant only after taking into consideration all factors relevant to that person’s independence from management. We will provide appropriate funding, as determined by the Compensation Committee, for payment of reasonable compensation to any independent compensation consultants or other external advisors retained by the Compensation Committee.

Risk Considerations

The Compensation Committee and the Board periodically review the risks associated with our compensation policies and practices. These assessments include an examination of the changes in our risk profile over the past year for our compensation policies and practices. Based on this assessment, the Compensation Committee and the Board each determined that these risks were not reasonably likely to have a material adverse effect on us. Among other things, the Compensation Committee and the Board took into consideration the fact that:

•

the current significant weighting towards long-term incentive compensation, the value of which depends on the value of our shares, discourages short-term risk taking;

•

our annual incentive compensation program includes several different metrics, preventing NEOs from focusing on one metric at the exclusion of other important performance goals;

•

our compensation program is appropriately balanced such that if annual bonus targets are not achieved, base pay and long-term incentive compensation will still provide the executives with a reasonable amount of compensation;

•

stock options and PSUs for executives vest over three years, which discourages short-term risk taking;

•

we maintain a clawback policy that requires us to recover certain excess incentive-based compensation in the case of a restatement of financial results due to material noncompliance with U.S. federal securities laws;

•

stock ownership guidelines encourage a long-term perspective by our executives; and

•

incentive awards are decided by the Compensation Committee and recommended to the Board for approval.

Compensation Peer Group – 2024

The following is our peer group for executive compensation purposes. The companies in the executive compensation peer group were selected with the assistance of our independent compensation consultant and consist of companies that are of similar size as Gran Tierra, are in the same line of business, and are listed on a major exchange in Canada or the United States. We included companies with an enterprise value of at least $0.7 billion and Working Interest production before royalties of 20,000+ BOEPD as of December 2024. We made no changes to our 2024 compensation per group from that used for 2023.

Elements of Our Compensation Program

Our executive compensation program includes a mix of fixed and variable pay with performance periods ranging from one to five years. The primary elements are summarized in the table below:



Compensation	Fixed/Variable	Cash/Equity	Time Period	Goal

Base Salary	Fixed	Cash	1 year	Provide fixed level of income

Short-term Incentive	Variable	Annual cash bonus	1 year	Reward contribution to annual corporate and individual performance

Long-term Incentive	Variable	PSUs RSUs	3 years 3 years	Reward medium and long-term performance and align interests of management and stockholders

Base Salary

We pay base salaries in order to attract and retain talented executives and to provide our NEOs with a fixed component of cash compensation. The salaries typically reflect each NEO’s experience, skills, knowledge and responsibilities. Competitive market conditions also have an impact on setting salary levels. Our Chief Executive Officer annually reviews the salaries of our NEOs other than his own, which is reviewed and determined by the Compensation Committee. The Compensation Committee works with independent compensation consultants to review and determine competitive compensation packages based on peer comparisons. In 2023, the Compensation Committee, with input from the independent consultants, reviewed the salaries and recommended to the Board an increase in the salaries for our executives. The changes in our NEOs’ base salaries from 2023 to 2024 are set forth in the table below.



Name	2024 Base Salary (1)	2023 Base Salary (1)	% Change 2023-2024

Gary S. Guidry	$486,449	$416,956	17%

Ryan Ellson	$347,463	$295,344	18%

Sebastien Morin (2)	$347,463	$43,299	N/A

Phillip D. Abraham	$234,538	$208,478	13%

Jim Evans	$283,761	$260,598	9%

(1)	For ease of comparison, amounts reported in this column are converted from Canadian dollars to U.S. dollars at the exchange rate of $1.4390 at December 31, 2024.

(2)	Sebastien Morin’s salary for 2023 was based on two months of employment with the Company.

Short Term Incentives – Cash Bonus

Our most critical compensation objective is for a significant portion of each NEO’s compensation to be tied to Company performance. Our annual cash bonus plan provides opportunities for our executives, including the NEOs, to earn annual cash bonuses tied to the successful achievement of key operational, financial and market objectives that drive our business and stockholder value.

In January, 2024 the Compensation Committee approved the annual bonus target for each of our NEOs which were calculated as a percentage of their respective base salaries.

The value of the bonus is calculated as below:

The following bonus structure was approved by the Compensation Committee for the following executives in connection with 2024 performance, which bonus structure was unchanged from the previous year:

Phillip D. Abraham		50	%		60	%		40	%

Jim Evans		50	%		60	%		40	%

Assessment of Individual Performance

Individual performance has a significant impact on the annual cash bonus for NEOs other than the Chief Executive Officer and is weighted between 20% and 40% of the award with the remaining amount being driven by our performance relative to our corporate performance measures. The individual performance rating for each NEO, other than the Chief Executive Officer, is determined through a formal performance evaluation conducted with the Chief Executive Officer. The performance evaluation measures how each NEO performs against criteria directly related to their position.

(1)	Amounts reported in these columns are converted from Canadian dollars to U.S. dollars at the exchange rate of $1.4390 at December 31, 2024. Final 2024 cash bonuses were paid in mid-February 2025.

Long-Term Equity Incentive Program

Our equity compensation program has been designed to incorporate equity awards that vest based on the achievement of key operational goals established by the Board of Directors as described below. Approximately 80% of the long-term equity incentive opportunity in 2024 consisted of PSUs and 20% consisted of RSUs, in each case, based on the award’s fair value at the grant date.

2024 PSUs Granted

As part of our long-term incentive plan, PSUs are designed to create a link between executive compensation and increased stockholder value by rewarding NEOs for achievement against key performance metrics over a three-year period. Our goal is to further incentivize our executives to achieve the operational goals established by the Board and to increase share and net asset value for our stockholders.

Each PSU entitles the holder to be issued the number of common shares designated in the performance award multiplied by a payout multiplier, with such common shares (or cash equal in value to such shares) to be issued on dates determined by the Compensation Committee, but by no later than March 10 of the year following the year in which the last performance period applicable to the award ends. The payout multiplier is determined based on the performance of the Company relative to

pre-defined

corporate performance measures for the period. The number of PSUs that vest may range from zero to 200% of the target number granted based on the performance multiplier earned under the terms of the award agreement. Each recipient must also remain in the continuous service of Gran Tierra from the date of grant through the date of settlement in order for the award to vest. PSUs are granted annually.

The PSUs granted to our NEOs in 2024 may become fully vested at the end of the overall performance period, based upon our performance with respect to four separate performance periods as follows:



Performance Period	Percentage of Target Award Subject to Performance Period

January 1, 2024—December 31, 2024		20	%

January 1, 2025—December 31, 2025		20	%

January 1, 2026—December 31, 2026		20	%

January 1, 2024—December 31, 2026		40	%

Total		100	%

The calculation of the performance multiplier is as follows:

•

50% weighting: Gran Tierra’s Total Shareholder Return (“TSR”) relative to that of peer companies in our Performance Peer Group;

•

25%weighting: Gran Tierra’s Financial Covenant Compliance and Free Cash Flow; and

•

25% weighting: execution of strategy (as determined by the Board).

Total Shareholder Return.

The Compensation Committee believes that the comparison of Gran Tierra’s TSR over a specified period of time to the returns of peer companies over the same period is an objective external measure of the Company’s



42		Gran Tierra Energy 2025 Proxy Statement

PROPOSAL 3: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

effectiveness in translating its results into stockholder returns. TSR is calculated by comparing Gran Tierra’s change in share price relative to the performance of a

pre-selected

peer group of companies with respect to the same measures. The framework included in the table below is used in determining our relative TSR.



Performance Level	TSR Percentile	Payout Multiplier

Lowest	< 25%	0

Middle	25% < 50%	1

Upper	50% < 75%	1.5

Maximum	>75%	2

The Compensation Committee approved the following total shareholder return performance peer group (the “Performance Peer Group”) for the 2024 PSUs, which is the same Performance Peer Group used for our 2023 PSUs:



Baytex Energy Corp.		Parex Resources Inc.

Callon Petroleum Company		Tamarack Valley Energy Ltd.

Canacol Energy Ltd.		W&T Offshore Inc.

Crescent Energy Company		Tullow Oil plc

Kosmos Energy Ltd.		Surge Energy Inc.

Matador Resources Company		Panoro Energy ASA

Frontera Energy Corporation		VAALCO Energy Inc.

Obsidian Energy Ltd.

If any of the peer companies undergoes a change in corporate capitalization or a corporate transaction (including, but not limited to, a going-private transaction, bankruptcy, liquidation, merger or consolidation) during the performance period, the Compensation Committee will undertake an evaluation to determine whether such peer company will be replaced.

The Performance Peer Group was developed with the assistance of our independent compensation consultants to meet at least one of the following specifications: an enterprise value of at least $1 billion; Proved Reserves of 30 million BOE; WI production before royalties of 20,000+ BOEPD; production to be at least 50% oil and natural gas liquids. Enterprise value was calculated as the market value of our common stock plus the market value of debt minus cash and investments.

Financial Covenant Compliance and Free Cash Flow.

The Company has a number of financial covenants that it must comply with in order to maintain good standing with its lenders. The Company must also generate Free Cash Flow calculated as funds from operations less capital expenditures before exploration expense and before annual cash incentive bonuses payment. Free Cash Flow was chosen as a performance metric for our PSUs because it provides an indication of the ability of the Company to execute its exploration program and paydown its debt. Financial covenant compliance and free cash flow demonstrates the Company’s ability to increase its underlying value without risking stockholder value and diluting stockholders. The framework included in the table below is used to assess Financial Covenant Compliance and Free Cash Flow performance. Results between the performance levels are interpolated on a linear basis.



Financial Covenant Compliance

Performance Level	Financial Covenant Compliance	Payout Multiplier (% of the Target Award)

Threshold	non-compliance	0

Target	compliance	200


Free Cash Flow

Performance Level	Free cash flow measured at end of year	Payout Multiplier (% of the Target Award)

Threshold	less than $10mm	0

Target	$20mm	100

Maximum	Greater than $30mm	200



Gran Tierra Energy 2025 Proxy Statement		43

PROPOSAL 3: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

Strategy.

Execution of strategy was chosen as a performance metric for our PSUs because it provides a link to the Company’s success in meeting key milestones and achieving its strategic goals. The Strategic Goals included metrics set by the Compensation Committee relating to acquisitions, exploration discoveries, financing and exploration commitments which have been included in the Company’s annual budget and subsequently approved by the Board.

The following table lists the number of PSUs awarded in 2024 at minimum, target, and maximum levels:



	Minimum # of units		Target # of units		Maximum # of units

Gary S. Guidry		0		300,268		600,536

Ryan Ellson		0		187,668		375,336

2024 Performance Results.

In February 2025, the Compensation Committee confirmed and approved the performance results for the portion of the 2022, 2023 and 2024 annual PSU awards that vest based on performance during the

one-year

performance period ended December 31, 2024 and continued employment through the end of 2024.

For the performance period ended December 31, 2024, the performance results were as follows:



	2024 Performance Factor Level	Weighting	Payout Multiplier

TSR – Relative TSR to peers	Target	50%	0.75

Financial Covenant Compliance and Free Cash Flow	Above Target	25%	0.50

Strategy Achievement	Above Target	25%	0.50

Benefits

The NEOs are eligible for full participation in all rights and benefits under any life insurance, disability, medical, dental, health and accident plans maintained by Gran Tierra for its employees and executive officers. Our executive officers generally do not receive any supplemental retirement benefits or perquisites, except for corporate health services and other immaterial perquisites that may be provided on a

case-by-case

basis from time to time. In addition, our employees including our executive officers will be paid 100% of their base salary in the event they become disabled while still employed by us, until such time as the executive officer begins to receive long-term disability insurance benefits which are intended to pay

two-thirds

of base salary to a maximum of $15,000/month to age 70. These are standard basic benefits in our industry and aid our ability to retain and recruit key talent. In addition, the NEOs are eligible to participate in the Company’s Employee Share Purchase Plan, under which employees may contribute up to 10% of their gross salary, which is then matched by the Company to be used to purchase undiscounted shares.

Share Ownership Guidelines

We have implemented share ownership guidelines for all of our executives, which are designed to align their long-term financial interests with those of our stockholders. The NEO share ownership guidelines are as follows:



Position	Guideline	Ownership Relative to Base Salary as of December 31, 2024

Chief Executive Officer	3 X base salary	Exceeds

Chief Financial Officer	2 X base salary	Exceeds

Chief Operating Officer	2 X base salary	On track

Executive Vice President, Corporate Services	1 X base salary	Exceeds

Executive Vice President, Legal and Land	1 X base salary	On track

If at any time an executive officer does not meet their ownership requirement, they must retain (a) any of our Com

on Stock owned by them (whether owned directly or indirectly) and (b) any net shares received as the result of the exercise, vesting or payment of any equity award until the ownership requirement is met, in each case unless otherwise approved by the Compensation Committee. For this purpose, “net shares” means the shares of stock that remain after shares are sold or withheld to (i) pay the exercise price for a stock option award or (ii) satisfy any tax obligations, including withholding taxes, arising in connection with the exercise, vesting or payment of an equity award.

Compliance with our share ownership requirements is evaluated as of December 31 of each year. The value of an individual’s share ownership as of such date is determined by multiplying the number of shares of our stock or other eligible equity interests held by the individual by the greater of the purchase price of the stock or the closing price on December 31 of each year.

In determining stock ownership levels, we include shares of common stock held directly or indirectly by the officer (including shares beneficially owned in a trust, by a limited liability company or partnership, and by a spouse and/or minor children). Outstanding RSUs, PSUs and unexercised stock options are not included. If an executive officer does not satisfy the stock ownership requirements, they must retain all shares acquired on the vesting of equity awards or the exercise of stock options (net of exercise costs and taxes) until compliance is achieved. All of the NEO’s are in compliance.

Clawback Provisions

We maintain a clawback policy that is intended to comply with the requirements of NYSE Stock Market Listing Standard303A.14 implementing Rule

10D-1

under the Exchange Act. In the event we are required to prepare an accounting restatement of our financial statements due to material

non-compliance

with any financial reporting requirement under the federal securities laws, we will recover the excess incentive-based compensation received by any covered executive, including our named executive officers, during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.



Gran Tierra Energy 2025 Proxy Statement		45

PROPOSAL 3: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

Prohibition on Speculative Trading of Company Stock

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, including our NEOs, directors and employees from trading during quarterly and special blackout periods.

Employment Agreements

The Compensation Committee approves the terms of all NEO employment agreements. The terms of those agreements were structured to attract and retain persons key to our success, as well as to be competitive with compensation practices for executives in similar positions at companies of similar size and complexity. In assessing whether the terms of the employment agreements were competitive, the Compensation Committee received advice from our independent compensation consultant and reviewed appropriate surveys and industry benchmarking data. The employment agreements do not have a fixed term. No changes were made to any of the NEO employment agreements already in place during 2024. The terms of the NEO employment agreements provide for certain payments and benefits in connection with a termination of employment and corporate transaction. The Compensation Committee believes these payments allow management to focus their attention and energy on making objective business decisions that are in the best interests of stockholders without allowing personal considerations to affect the decision-making process. Additionally, executive officers at other companies in our industry and the general market in which we compete for executive talent commonly provide post-termination payments, and we have consistently provided this benefit to certain executives in order to remain competitive in attracting and retaining skilled professionals in our industry. In 2017, the Company’s pay practices were amended so that no new employment agreements entered into between Gran Tierra and executive officers will include any provisions that provide for excise tax

gross-ups

or “single” or “modified single” triggers resulting in severance payments or accelerated vesting of equity awards upon a change in control.

Equity Grant Practices

PSUs and RSUs are typically awarded at our board and compensation committee meetings in February, or in the case of any new employees, such later date on which such grantee commences employment with the Company. We did not time the disclosure of material nonpublic information for the purpose of affecting the value of any executive compensation awarded during fiscal 2024.

Say on Pay Advisory Vote on Executive Compensation

The Company asked stockholders to vote on a

“say-on-pay”

advisory vote on our executive compensation in 2024 at the 2024 annual meeting of stockholders. Stockholders expressed support for the compensation of our named executive officers, with approximately 89.48% of the votes cast in favor of the

“say-on-pay”

advisory vote. Given the level of stockholder support, the Company did not make any material changes to our compensation programs in 2024 as a result of the

“say-on-pay”

advisory vote. The Compensation Committee also considers many other factors in evaluating our executive compensation programs as discussed in the Executive Compensation section, including the Compensation Committee’s assessment of the interaction of our compensation programs with our corporate business objectives and review of peer group data, each of which is evaluated in the context of the Compensation Committee’s duty to act in the best interests of our stockholders.

REPORT OF THE COMPENSATION COMMITTEE

The Compensation Committee has reviewed and discussed with management the Company’s disclosure under “Executive Compensation” contained in this proxy statement. Based on such review and discussion, the Compensation Committee recommended to the Board of Directors that the Executive Compensation be included in this proxy statement:

(1)	Calculated using $7.23 which was the closing price shares of Gran Tierra’s common stock on December 31, 2024.

(2)	These amounts include the tranches of the PSU awards granted in February 2022 which were vested December 31, 2024 and were settled in March 15, 2025.

(3)

Provided that our NEOs remain employed through the settlement date, these amounts represent the number of shares of common stock, or their cash equivalent, deliverable to each NEO with respect to the first and second tranches (representing 40% of the target amount) of the PSU award granted on February 23, 2023. These amounts represent the actual number of shares of common stock, or their cash equivalent, earned pursuant to the terms of the PSUs for the performance period from January 1, 2023 through December 31, 2023, and the period January 1, 2024 through December 31, 2024. The first tranche became earned at 50% of target and the second tranche became earned at 200% of target. The awards are enumerated in this column because while the performance element of vesting for the awards has been fulfilled, the continued service requirement for vesting has not. If the NEOs do not remain employed through the settlement date, they will forfeit the awards. As such, the awards were not fully vested as of December 31, 2024.

(4)

These amounts include the tranches (representing 40% of the target amount) of the PSU award granted on February 23, 2023 the vesting of which is still subject to performance conditions. The applicable performance period for the third tranche (representing 20% of the target amount) is January 1, 2024 through December 31, 2024. The fourth tranche (representing 40% of the target amount) has a performance period which began on January 1, 2022 and will end on December 31, 2024.

(5)	These options vest one-third on February 24, 2023, one-third on February 24, 2024, and one-third on February 24, 2025, in each case if the option holder is still employed by Gran Tierra on such date.

COMPENSATION DISCUSSION AND ANALYSIS

(6)

Provided that our NEOs remain employed through the settlement date, these amounts represent the number of common shares, or their cash equivalent, deliverable to each NEO with respect to the first tranche (representing 20% of the target amount) of the PSU award granted on February 22, 2024. These amounts represent the actual number of common shares, or their cash equivalent, earned pursuant to the terms of the PSUs for the performance period from January 1, 2024 through December 31, 2024. The awards are enumerated in this column because while the performance element of vesting for the awards has been fulfilled, the continued service requirement for vesting has not. If the NEOs do not remain employed through the settlement date, they will forfeit the awards. As such, the awards were not fully vested as of December 31, 2024.

(7)

These amounts include the tranches (representing 80% of the target amount) of the PSU award granted on February 22, 2024 the vesting of which is still subject to performance conditions. The applicable performance period for the second tranche (representing 20% of the target amount) is January 1, 2024 through December 31, 2024, and the applicable performance period for the third tranche (representing 20% of the target amount) is January 1, 2025 through December 31, 2025. The fourth tranche (representing 40% of the target amount) has a performance period which began on January 1, 2024 and will end on December 31, 2025. The amounts above represent the maximum number of the PSUs that may vest. The actual number of PSUs that vest pursuant to the PSU award granted on February 22, 2024 will depend on our performance over the applicable performance periods and the NEOs continued employment through the date of settlement.

(8)	These options vest one-third on February 23, 2024, one-third on February 23, 2025 and one-third on February 23, 2026, in each case if the option holder is still employed by Gran Tierra on such date.

(9)	These options vest one-third on November 6, 2024 one-third on November 6, 2025 and one-third on November 6, 2026, in each case if the option holder is still employed by Gran Tierra on such date.

2024 STOCK VESTED

The following table presents information concerning the PSUs that vested during the fiscal year ended December 31, 2024, for the NEOs.

(1)	All PSUs that vested during 2024 were settled in cash, and accordingly no shares of common stock were issued in respect of such awards.

(2)	The amounts in this column were calculated by multiplying the number of shares of common stock subject to the PSU that vested in 2024 by $6.79 which was the 10 day VWAP price of shares of Gran Tierra’s common stock on December 31, 2024.

Potential Payment Upon Termination or Change of Control

In the event that any of our NEOs dies, voluntarily resigns without “good reason”(as defined below), or the NEO’s employment is terminated by Gran Tierra for “cause” (as defined below), the NEO will not be entitled to receive any further compensation or benefits other than those which have accrued up to the NEO’s last day of active service.

Messrs. Guidry, Ellson, Morin, Evans and Abraham are entitled to severance payments in the event of an involuntary termination of employment by Gran Tierra other than for cause or a termination of employment by the NEO for good reason, as follows:

EXECUTIVE COMPENSATION

Under the terms of Mr. Guidry’s employment agreement, to the extent that (i) he is required to file a U.S. income tax return with the Internal Revenue Service and (ii) certain payments or benefits received or to be received by him constitute “parachute payments” within the meaning of Section 280G of the Code that will be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the Company will pay to Mr. Guidry, no later than the time such Excise Tax is required to be paid by Mr. Guidry or withheld by the Company, an additional amount equal to the sum of the Excise Tax payable by Mr. Guidry, plus an additional amount necessary to put him in the same

after-tax

position as if no Excise Tax had been imposed. In 2024, this amount would have been $3,198,503, calculated as follows:



Total termination payment		$6,150,973

Gross-Up of taxable income		2,229,922

Total taxable income		8,380,895

Canadian tax payable		(4,022,832)

Net cash		4,358,063

US Excise tax payable		(1,159,560)

Net after tax		$3,198,503

Pursuant to the employment agreements for each of Messrs. Guidry, Ellson, Morin, Evans and Abraham, “cause” means any act or omission of the executive which would, at common law, permit an employer to terminate the employment of an employee without notice or payment in lieu of notice.

As defined in the employment agreements for each of Messrs. Guidry, Ellson, Morin, Evans and Abraham, “good reason” generally means any of the following without the executive’s express written consent:

(a) an adverse change in position, titles, duties or responsibilities, except in connection with the termination of employment for cause;

(b) a reduction by the company of the executive’s base salary except to the extent that the annual base salaries of all other executive officers are similarly reduced or any change in the basis upon which the Executive’s annual compensation is determined or paid if the change is adverse to the executive (excluding changes to the annual bonus);

(d) any breach by the Company of any material provision of the employment agreement.

The following events will generally constitute a “change in control” pursuant to the employment agreements with each of Messrs. Guidry, Ellson, Morin, Evans and Abraham:

(1) a disposition of all or substantially all of the assets of Gran Tierra Energy Inc. or GTE Alberta Inc.;

(2) a majority of the voting securities of GTE Alberta Inc. cease to be controlled, directly or indirectly, by Gran Tierra Energy Inc.; or

(3) a merger or other transaction of Gran Tierra Energy Inc. with or into another company pursuant to which any person or combination of persons thereafter holds a greater number of voting securities of the continuing company than the number of voting securities of the continuing company held by former shareholders of Gran Tierra Energy, Inc.

Upon a termination of employment, each of Messrs. Guidry, Ellson, Morin, Evans and Abraham forfeit any unvested RSUs and stock options.

Unvested equity awards will accelerate and become fully vested immediately prior to a Corporate Transaction. With respect to stock options, the value is calculated as (a) the difference between $7.23, the closing price of our common stock on December 31, 2024, and the exercise price of the applicable option, multiplied by (b) the number of unvested options subject to accelerated vesting held by the applicable NEO. With respect to PSUs/RSUs, the value is calculated as (a) $7.23, the closing price of our common stock on December 31, 2024, multiplied by (b) the number of unvested PSUs/RSUs subject to accelerated vesting held by the applicable NEO, assuming a performance factor of 1 for the PSUs.

Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Act, we are providing the following information about the relationship of the annual total compensation of our employees (other than our Chief Executive Officer) and the annual total compensation of our Chief Executive on December 31, 2024.

In determining our median employee, we prepared a list of all employees as of December 31, 2024. Consistent with SEC rules, we used reasonable estimates both in the methodology used to identify the median employee and in calculating the annual total compensation for employees other than the Chief Executive Officer. In measuring our employees’ total compensation, for employees other than the Chief Executive Officer, we used their base salary paid in 2024, their annual cash bonus paid in 2024 and grant date fair value of the equity awards they received in 2024. Total compensation for Gary S. Guidry, our Chief Executive Officer, was determined to be 3,017,224 and was approximately 44 times the median annual compensation of all Company employees excluding the Chief Executive Officer, which as of December 31, 2024 was_$69,323. For purposes of this calculation, the Company had 430 employees in Canada, Colombia, and Ecuador excluding the Chief Executive Officer.

The names of each of the NEOs (excluding our CEO) included for purposes of calculating the average amounts in each of the five years are as follows: for 2024: Ryan Ellson, Sebastien Morin, Jim Evans and Phillip D. Abraham; for 2023 (during which we were a smaller reporting company and therefore subject to reduced disclosure obligations regarding executive compensation): Ryan Ellson, Jim Evans, and for 2022, 2021 and 2020: Ryan Ellson, Jim Evans, Rodger Trimble, our former Vice President, Investor Relations, and Lawrence West, Vice President, Exploration.

Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.

6	Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: S&P O&G E&P Select Index Total Return.

7	The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year.

EBITDA is a key indicator of a business’s performance, profitability, value and ability to add debt. It’s a picture of the core profit of a company and provides a picture of its available cash flow. Adjusted EBITDA, as presented, is defined as EBITDA adjusted for asset impairment, goodwill impairment,

non-cash

lease expense, lease payments, unrealized foreign exchange gains or losses, unrealized derivative instruments gains or losses, other financial instruments gains or losses, other

non-cash

gains or losses, and stock-based compensation expense. Management uses this supplemental measure to analyze performance and income generated by our principal business activities prior to the consideration of how

non-cash

items affect that income and believes that this financial measure is a useful supplemental information for investors to analyze our performance and our financial results. A reconciliation from net income or loss to EBITDA and adjusted EBITDA is available in the Company’s Annual Report.

As described in greater detail in “Executive Compensation – Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable

pay-for-performance

philosophy. The metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:

•

1P Reserve Replacement

•

Lifting Costs

•

Free Cash Flow

Analysis of the Information Presented in the Pay versus Performance Table

As described in more detail in the section “Executive Compensation – Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable

pay-for-performance

philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with SEC rules) for a particular year. In accordance with SEC rules, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other annual meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other annual meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are stockholders of Gran Tierra will be “householding” Gran Tierra’s proxy materials. A single Notice of Internet Availability of Proxy Materials or a single set of annual meeting materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice of Internet Availability of Proxy Materials or a separate set of annual meeting materials, please notify your broker. You can also request prompt delivery of a copy of the proxy statement and annual report by contacting Gran Tierra Energy Inc., Corporate Secretary, 500 Centre Street S.E., Calgary, Alberta, Canada T2G 1A6 or by telephone at (403) 265-3221. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials or multiple sets of annual meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

Other Matters

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 meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

By Order of the Board of Directors

Forward Looking Statements Advisory

This proxy statement contains forward-looking statements regarding the Company within the meaning of applicable securities laws and regulations. These statements include those relating to the Company’s plans, goals and expectations. They are subject to a variety of risks and uncertainties that could cause actual results to differ materially from expectations. These risks and uncertainties include, but are not limited to, the risks detailed in the Company’s filings with the Securities and Exchange Commission, including the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. The forward-looking statements speak only as of the date of this proxy statement, and we assume no obligation to update any of these forward-looking statements, except as required by law.

Disclosure of Oil and Gas Information

Gran Tierra’s Statement of Reserves Data and Other Oil and Gas Information on Form 51-101F1 dated effective as at December 31, 2024 (the “GTE 51-101F1”), which includes disclosure of its oil and gas reserves and other oil and gas information in accordance with Canadian National Instrument 51-101 – Standards of Disclosure for Oil and Gas Activities (“NI 51-101”) and the Canadian Oil and Gas Evaluation Handbook (“COGEH”) forming the basis of this document, is available on SEDAR at www.sedar.com. All reserves values, future net revenue and ancillary information contained herein are as of December 31, 2024, are derived from a report with an effective date of December 31, 2024 (the “GTE McDaniel Reserves Report”) prepared by Gran Tierra’s independent qualified reserves evaluator McDaniel & Associates Consultants Ltd. (“McDaniel”) and calculated in compliance with NI 51-101 and COGEH.

Estimates of net present value contained herein do not necessarily represent fair market value of reserves or resources. Estimates of reserves or resources and future net revenue for individual properties may not reflect the same level of confidence as estimates of reserves and future net revenue for all properties, due to the effect of aggregation. There is no assurance that the forecast price and cost assumptions applied by McDaniel in evaluating Gran Tierra’s reserves will be attained and variances could be material. All reserves assigned in the GTE McDaniel Reserves Report are located in Colombia and Ecuador and presented on a consolidated basis by foreign geographic area. There are numerous uncertainties inherent in estimating quantities of crude oil reserves and the future cash flows attributed to such reserves. The reserve and associated cash flow information set forth in the GTE McDaniel Reserves Report are estimates only. References to a formation where evidence of hydrocarbons has been encountered is not necessarily an indicator that hydrocarbons will be recoverable in commercial quantities or in any estimated volume. Gran Tierra’s reported production is a mix of light crude oil and medium and heavy crude oil for which there is no precise breakdown since the Company’s oil sales volumes typically represent blends of more than one type of crude oil. Drilling locations disclosed herein are derived from the GTE McDaniel Reserves Report and account for drilling locations that have associated Undeveloped and Proved plus Probable Undeveloped reserves, as applicable.

Gas volumes are converted to BOE at the rate of 6 Mcf of gas per bbl of oil, based upon the approximate relative energy content of gas and oil. The rate is not necessarily indicative of the relationship between oil and gas prices. BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf:1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, given that the value ratio based on the current price of oil as compared with natural gas is significantly different from the energy equivalent of six to one, utilizing a BOE conversion ratio of 6 Mcf: 1 bbl would be misleading as an indication of value.

This document contains a number of oil and gas metrics, including reserves replacement, net asset value (“NAV”) per share and FD&A costs, which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies and should not be used to make comparisons. Such metrics have been included herein to provide readers with additional measures to evaluate the Company’s performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods.

•

Reserves replacement is calculated as reserves in the referenced category per the GTE McDaniel Reserves Report divided by estimated referenced production. Management uses this measure to determine the relative change of its reserve base over a period of time.



60		Gran Tierra Energy 2025 Proxy Statement

•

NAV per share is calculated as net asset value at 10% discount (before or after tax, as applicable) of the applicable reserves category per the GTE McDaniel Reserves Report minus estimated debt, divided by the number of shares of Gran Tierra’s common stock issued and outstanding. Management uses NAV per share as a measure of the relative change of Gran Tierra’s net asset value over its outstanding common stock over a period of time.

•

FD&A costs are calculated as estimated exploration and development capital expenditures in Colombia, divided by the applicable reserves additions per the GTE McDaniel Reserves Report both before and after changes in FDC. The calculation of FD&A costs incorporates the change in FDC required to bring proved undeveloped and developed reserves into production. The aggregate of the exploration and development costs incurred in the financial year and the changes during that year in estimated FDC may not reflect the total FD&A costs related to reserves additions for that year. Management uses FD&A costs as a measure of its ability to execute its capital program and of its asset quality.

Definitions

All dollar ($) amounts referred to in this proxy statement are United States (U.S) dollars, unless otherwise indicated.

BOE means barrels of oil equivalent.

BOEPD means barrels of oil equivalent per day.

MMBOE means million barrels of oil equivalent.

Proved (1P) reserves are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves.

Probable reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves.

Possible reserves are those additional reserves that are less certain to be recovered than Probable reserves. There is a 10% probability that the quantities actually recovered will equal or exceed the sum of Proved plus Probable plus Possible reserves. The estimate of reserves for individual properties may not reflect the same confidence level as estimates of reserves for all properties, due to the effects of aggregation.

Undeveloped reserves are those reserves expected to be recovered from known accumulations where a significant expenditure (e.g., when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves category (proved, probable, possible) to which they are assigned.

See the GTE 51-101F1 for additional definitions regarding terms used in this document.

In the event we are required to prepare an accounting restatement of our financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws, we will recover the excess incentive-based compensation received by any covered executive, including our named executive officers, during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.
