Gran Tierra Shareholders may use the figure of 36,460,141 as the denominator in calculations to determine if they are required to notify Gran Tierra of their interest in, or a change to their interest in Gran Tierra under the Financial Conduct Authority's Disclosure Guidance and Transparency Rules.

Cancellation of the Trafigura Loan Facility

Gran Tierra also announces that the Loan Facility entered into on 19 August 2024 with Trafigura has today been cancelled. As announced on 18 September 2024, Gran Tierra completed an offering of an additional US$ 150 million aggregate principal amount of its 9.500% Senior Secured Amortizing Notes due 2029, the net proceeds of which are being applied to satisfy the cash consideration payable to i3 Energy Shareholders in place of the term loan facility available to Gran Tierra pursuant to the terms of the Loan Facility.

Overseas Shareholders

Any failure to comply with the restrictions may constitute a violation of the securities laws of any such jurisdiction.

The release, publication or distribution of this announcement in or into or from jurisdictions other than the United Kingdom may be restricted by law and therefore any persons who are subject to the laws of any jurisdiction other than the United Kingdom should inform themselves about, and observe, such restrictions.

Accordingly, copies of this announcement and all documents relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and persons receiving this document and all documents relating to the Acquisition (including custodians, nominees and trustees) must observe these restrictions and must not mail or otherwise distribute or send them in, into or from such jurisdictions where to do so would violate the laws in that jurisdiction. Doing so may render invalid any purported vote in respect of the Acquisition.

Dealing and Opening Position Disclosure Requirements

Under Rule 8.3(a) of the Takeover Code, any person who is interested in one per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the Offer Period and, if later, following the announcement in which any securities exchange offeror is first identified.

An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 p.m. (London time) on the 10th Business Day following the commencement of the Offer Period and, if appropriate, by no later than 3.30 p.m. (London time) on the 10th Business Day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Takeover Code, any person who is, or becomes, interested in one per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 p.m. (London time) on the Business Day following the date of the relevant dealing. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4). Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the Offer Period commenced and when any offeror was first identified. You should contact the Panel's Market Surveillance Unit on +44 20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.

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 effects of the Acquisition on Gran Tierra and i3 Energy, the expected timing and method of completion, and scope of the Acquisition, 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.
