RECOMMENDED AND FINAL CASH AND SHARE ACQUISITION

for

i3 Energy plc ("i3 Energy")

by

Gran Tierra Energy Inc. ("Gran Tierra")

implemented by way of a scheme of arrangement under Part 26 of the Companies Act 2006

Results of Elections under the Mix and Match Facility

On 19 August 2024, the boards of directors of i3 Energy and Gran Tierra announced that they had reached agreement on the terms of a recommended and final cash and share acquisition of the entire issued, and to be issued, share capital of i3 Energy (the "Acquisition"). The Acquisition is being implemented by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006.

i3 Energy published a circular in relation to the Scheme dated 29 August 2024 (the "Scheme Document").

On 29 October 2024, i3 Energy announced that the Court had sanctioned the Scheme at the Sanction Hearing held on 29 October 2024. Furthermore, on 31 October 2024 Gran Tierra announced that the scheme had become effective and the i3 Energy shares were suspended on the AIM market at 7:30 a.m. on 31 October 2024. Trading of i3 Energy shares was halted on the TSX at market open on 30 October 2024.

Under the Scheme, Scheme Shareholders on i3 Energy's register of members at the Scheme Record Time are entitled to receive 1 New Gran Tierra Share for every 270 Scheme Shares held and 10.43 pence in cash for each Scheme Share held, subject to any adjustments to such consideration resulting from valid Elections made pursuant to the Mix and Match Facility. The deadline for receipt of valid Elections under the Mix and Match Facility was 1.00 p.m. on 22 October 2024.

Under the Mix and Match Facility, valid Elections for more New Gran Tierra Shares were received from Scheme Shareholders in respect of 5,397,705 Scheme Shares, representing approximately 0.45 per cent. of the aggregate number of Scheme Shares, and valid Elections for more cash were received from Scheme Shareholders in respect of 528,817,169 Scheme Shares, representing approximately 43.98 per cent. of the aggregate number of Scheme Shares.

The ability to satisfy Elections was dependent upon Scheme Shareholders making equal and opposite Elections.

Scheme Shareholders who made valid Elections for more New Gran Tierra Shares have had such Elections satisfied in full. In respect of the Scheme Shares for which valid Elections have been received for more New Gran Tierra Shares and which have been satisfied, Scheme Shareholders will receive 0.02042172 of a New Gran Tierra Share per Scheme Share.

Scheme Shareholders who made valid Elections for more cash have had such Elections scaled back on a pro rata basis by approximately 96.7 per cent. so that approximately 3.3 per cent. of a valid Election for more cash has been satisfied. In respect of Scheme Shares for which a valid Election has been made for more cash, Scheme Shareholders will receive 10.536460 pence in cash per Scheme Share and 0.004672 of a new Gran Tierra share per Scheme Share.

Scheme Shareholders who did not make valid Elections have not participated in the Mix and Match Facility. In respect of Scheme Shares for which no valid Elections have been made, Scheme Shareholders will receive the default consideration, being 1 New Gran Tierra Share for every 270 Scheme Shares held and 10.43 pence in cash per Scheme Share.

Forward Looking Statements

This announcement (including information incorporated by reference into this announcement), oral statements regarding the Acquisition and other information published by Gran Tierra and i3 Energy contain certain forward-looking statements with respect to the financial condition, strategies, objectives, results of operations and businesses of Gran Tierra and i3 Energy and their respective groups and certain plans and objectives with respect to the Combined Group. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of the management of Gran Tierra and i3 Energy about future events, and are therefore subject to risks and uncertainties which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements. The forward looking statements contained in this announcement include, without limitation, statements relating to the expected method of completion, the expected actions of i3 Energy and Gran Tierra upon completion of the Acquisition and other statements other than historical facts. Forward looking statements often use words such as "anticipate", "target", "expect", "estimate", "intend", "plan", "strategy", "focus", "envision", "goal", "believe", "hope", "aims", "continue", "will", "may", "should", "would", "could", or other words of similar meaning. These statements are based on assumptions and assessments made by Gran Tierra, and/or i3 Energy in light of their experience and their perception of historical trends, current conditions, future developments and other factors they believe appropriate. By their nature, forward looking statements involve risk and uncertainty, because they relate to events and depend on circumstances that will occur in the future and the factors described in the context of such forward looking statements in this announcement could cause actual results and developments to differ materially from those expressed in or implied by such forward looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and readers are therefore cautioned not to place undue reliance on these forward-looking statements. Actual results may vary from the forward-looking statements.

There are several factors which could cause actual results to differ materially from those expressed or implied in forward looking statements. Among the factors that could cause actual results to differ materially from those described in the forward-looking statements are changes in the global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates and future business acquisitions or dispositions.

Each forward-looking statement speaks only as at the date of this announcement. Neither Gran Tierra nor i3 Energy, nor their respective groups assume any obligation to update or correct the information contained in this announcement (whether as a result of new information, future events or otherwise), except as required by applicable law or by the rules of any competent regulatory authority.
