Gran Tierra Completes Sale of Colombian and Ecuadorian Assets

CALGARY, Alberta, Sept. 22, 2026 /CourierPR/ -- Gran Tierra Energy Inc., a global independent energy company, today announced the successful completion of a key transaction that will significantly reshape its business portfolio. The company has sold its Colombian and Ecuadorian oil and gas assets to Maurel & Prom, a major international oil and gas company, for a total consideration of approximately $1.33 billion, subject to certain adjustments. This strategic move marks a pivotal moment in Gran Tierra's evolution, as it transitions its focus to its core operations in Canada.

The sale, which was previously announced, was contingent upon Gran Tierra securing the necessary consents from the holders of its 9.750% Senior Secured Amortizing Notes due 2031. These notes, which were issued under the indenture dated February 18, 2026, required the approval of a substantial majority of the outstanding notes to proceed. The company successfully obtained this majority support through a previously announced solicitation of consents, known as the Consent Solicitation.

The Consent Solicitation, conducted in conjunction with the sale, aimed to secure the necessary consents from the holders of the Notes to effect certain proposed amendments to the indenture. The proposed amendments were designed to facilitate the sale and align the terms of the Notes with the sale's terms and conditions. The solicitation statement, dated September 11, 2026, provided detailed information on the process and the terms of the proposed amendments.

As of September 22, 2026, Gran Tierra Energy Inc. had received consents from holders of not less than 50% in aggregate principal amount of the Notes, ensuring the necessary majority support was achieved. This significant milestone allowed the company to proceed with the execution of the Supplemental Indenture, which was executed on September 22, 2026, by the Company, the Note Guarantors, and the Trustee. The Supplemental Indenture became effective immediately upon execution but will only become operative on the closing date of the sale, at which time it will be binding on all holders of the Notes, including those who did not deliver a consent prior to such execution.

The sale of the Colombian and Ecuadorian assets will allow Gran Tierra Energy Inc. to concentrate its operations in Canada, where it will continue to pursue its exploration interests in Azerbaijan and explore new growth opportunities that will further strengthen its portfolio. The company's common stock is currently traded on the NYSE American, the Toronto Stock Exchange, and the London Stock Exchange under the ticker symbol GTE.

Gran Tierra Energy Inc. has filed a definitive proxy statement with the SEC to solicit stockholder approval of the transaction. Detailed information about the sale is contained in the proxy statement and other documents filed with the SEC. The company's filings with the SEC are available on the SEC website at www.sec.gov, and its Canadian securities regulatory filings are available on SEDAR+ at www.sedarplus.ca, while UK regulatory filings are available on the National Storage Mechanism website at data.fca.org.uk#/nsm/nationalstoragemechanism.

Gran Tierra Energy Inc. has emphasized that the sale is a significant step in the company's strategic evolution, positioning it to focus on its core operations in Canada and pursue new growth opportunities. The company remains committed to its environmental, social, and governance (ESG) commitments and will continue to operate in a manner that aligns with its values and the evolving needs of its stakeholders.
