  49. DIRECTOR COMPENSATION

    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. The director compensation structure for non-executive directors as of January 1, 2025 was as follows:

  50. DIRECTOR COMPENSATION

    | | 2025 Annual Cash Retainer and Travel Fees (1) | 2025 Annual Equity Retainer (DSUs, RSUs, Stock Options) (1) | | Board Chair | $67,400 | $138,444 | | Board Member | $40,076 | $116,948 | | Audit Committee Chair | $32,789 | | | Other Committee Chairs | $21,860 | | | Committee Members | $10,930 | | | Travel Fee (over three hours) per meeting | $1,093 | |

  51. DIRECTOR COMPENSATION

    | (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, 2025 was used for this purpose and was one US dollar to Canadian $1.3724. |

  52. DIRECTOR COMPENSATION

    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.

  61. Role of the Independent Compensation Consultant

    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.

  62. Risk Considerations

    | • | 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; |

  63. Risk Considerations

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

  64. Risk Considerations

    | • | 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; |

  65. Risk Considerations

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

  66. Risk Considerations

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

  67. Risk Considerations

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

    Assessment of Individual Performance Individual performance has a significant impact on the annual cash bonus for NEOs other than the President and 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 President and Chief Executive Officer, is determined through a formal performance evaluation conducted with the President and Chief Executive Officer. The performance evaluation measures how each NEO performs against criteria directly related to their position. 2025 Corporate Performance Goals and Scores Results between the Company’s Corporate Target can be interpolated on a linear basis. The lower number results in a multiplier of 0, middle results in a multiplier of 1 and the upper threshold is a multiplier of 2.

  87. Long-Term Equity Incentive Program

    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 2025 consisted of PSUs and 20% consisted of RSUs, in each case, based on the award’s fair value at the grant date. 2025 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 2025 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:

  88. Long-Term Equity Incentive Program

    | Performance Period | Percentage of Target Award Subject to Performance Period | | January 1, 2025—December 31, 2025 | 20% | | January 1, 2026—December 31, 2026 | 20% | | January 1, 2027—December 31, 2027 | 20% | | January 1, 2025—December 31, 2027 | 40% | | Total | 100% |

  89. Long-Term Equity Incentive Program

    The calculation of the performance multiplier is as follows:

  90. Long-Term Equity Incentive Program

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

  91. Long-Term Equity Incentive Program

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

  92. Long-Term Equity Incentive Program

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

  93. Long-Term Equity Incentive Program

    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

  94. Long-Term Equity Incentive Program

    | Gran Tierra Energy 2026 Proxy Statement | 37 |

  95. Long-Term Equity Incentive Program

    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.

  96. Long-Term Equity Incentive Program

    | Performance Level | TSR Percentile | Payout Multiplier | | Lowest | < 25% | 0 | | Middle | 25% < 50% | 1 | | Upper | 50% < 75% | 1.5 | | Maximum | >75% | 2 |

  97. Long-Term Equity Incentive Program

    The Compensation Committee approved the following total shareholder return performance peer group (the “Performance Peer Group”) for the 2025 PSUs, which is the same Performance Peer Group used for our 2024 PSUs:

  98. Long-Term Equity Incentive Program

    | 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. | |

  99. Long-Term Equity Incentive Program

    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.

  100. Long-Term Equity Incentive Program

    | Financial Covenant Compliance | | | | Performance Level | Financial Covenant Compliance | Payout Multiplier (% of the Target Award) | | Threshold | non-compliance | 0 | | Target | compliance | 200 | | 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 |

  102. Long-Term Equity Incentive Program

    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 2025 at minimum, target, and maximum levels:

  103. Long-Term Equity Incentive Program

    | | Minimum # of units | Target # of units | Maximum # of units | | Gary S. Guidry | 0 | 229,508 | 459,016 | | Ryan Ellson | 0 | 143,443 | 286,886 | | Sebastien Morin | 0 | 143,443 | 286,886 |

    2025 Performance Results. On February 24, 2026, the Compensation Committee confirmed and approved the performance results for the portion of the 2023, 2024 and 2025 annual PSU awards that vest based on performance during the one-year performance period ended December 31, 2025 and continued employment through the end of 2025. For the performance period ended December 31, 2025, the performance results were as follows:

  105. Long-Term Equity Incentive Program

  116. Employment Agreements

    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 2025. 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.

  117. Equity Grant Practices

    Equity Grant Practices PSUs and RSUs are typically approved at the meeting of the Compensation Committee in February and granted at the subsequent meeting of our Board, or in the case of any new employees, such later date on which such grantee commences employment with the Company. We do not time the disclosure of material nonpublic information for the purpose of affecting the value of any executive compensation awards.

  149. 2025 STOCK VESTED

    | (1) All PSUs that vested during 2025 were settled in cash, and accordingly no shares of common stock were issued in respect of such awards. |

  150. 2025 STOCK VESTED

    | (2) The amounts in this column were calculated by multiplying the number of shares of common stock subject to the PSU that vested in 2025 by $4.07 which was the 10 day VWAP price of shares of Gran Tierra’s common stock on the last trading day of the year, December 31, 2025. |

  151. Potential Payment Upon Termination or Change of Control

    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 and Morin 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:

  154. Potential Payment Upon Termination or Change of Control

    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 2025, this amount would have been $2,626,008, calculated as follows:

  155. Potential Payment Upon Termination or Change of Control

    | Total termination payment | $5,050,017 | | Gross-Up of taxable income | 1,763,778 | | Total taxable income | 6,813,795 | | Canadian tax payable | (3,270,622) | | Net cash | 3,543,173 | | US Excise tax payable | (917,165) | | Net after tax | $2,626,008 |

  156. Potential Payment Upon Termination or Change of Control

    Pursuant to the employment agreements for each of Messrs. Guidry, Ellson and Morin, “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 and Morin “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); (c) a change in control (as defined below) of Gran Tierra Energy Inc. or GTE Alberta Inc. occurs; or (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 and Morin: (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 stockholders of Gran Tierra Energy, Inc. Upon a termination of employment, each of Messrs. Guidry, Ellson and Morin forfeit any unvested RSUs and stock options.

    | (1) 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 $4.24, the closing price of our common stock on December 31, 2025, 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) $4.24, the closing price of our common stock on December 31, 2025, 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. |

  161. Pay Ratio Disclosure

    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, 2025. In determining our median employee, we prepared a list of all employees as of December 31, 2025. 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 2025, their annual cash bonus paid in 2025 and grant date fair value of the equity awards they received in 2025. Total compensation for Gary S. Guidry, our Chief Executive Officer, was determined to be 3,086,301 and was approximately 37 times the median annual compensation of all Company employees excluding the Chief Executive Officer, which as of December 31, 2025 was $82,817. For purposes of this calculation, the Company had 469 employees in Canada, Colombia, and Ecuador excluding the Chief Executive Officer.

    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 stockholders. 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:

    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.
