Proposals
The Board of Directors is nominating the five individuals identified below for election as directors. Unless you specify differently, proxies received will be voted FOR each of Robert B. Hodgins, Gary S. Guidry, Alison M. Redford, Ronald W. Royal and Brooke Wade. Each director to be elected and qualified will hold office until the next annual meeting of stockholders and until his or her successor is elected, or, if sooner, until the director’s death, resignation or removal. Each of the nominees listed below is currently a director of Gran Tierra. Each of the nominees was last elected at the 2025 annual meeting of stockholders. It is Gran Tierra’s policy to invite nominees for directors to attend the annual meeting and all of the Directors in office at the time, attended the 2025 annual meeting of stockholders.
Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the five nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by Gran Tierra.
THE BOARD RECOMMENDS A VOTE “FOR” EACH OF THE NOMINEES.
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.
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 32 to 42 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 2027.
THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” PROPOSAL 3.
