GRAN TIERRA ENERGY INC. ANNOUNCES GRANTING OF EXEMPTIVE RELIEF REGARDING ITS NORMAL COURSE ISSUER BID

Gran Tierra Energy Inc. has obtained an exemption order from the Canadian securities regulators, which permits Gran Tierra to purchase up to 10 per cent of its public float (within the meaning of the rules of the Toronto Stock Exchange) of shares of common stock through the NYSE American and other trading systems based in the United States as part of Gran Tierra's normal course issuer bids announced on Oct. 31, 2023. Absent this exemptive relief, Gran Tierra's purchases under a normal course issuer bid on markets other than the TSX would be limited to not more than 5 per cent of its outstanding shares over any 12-month period. A substantial majority of the trading volume of Gran Tierra's shares occurs through the U.S. markets.

The exemptive relief is applicable to purchases of shares completed within 36 months of the Feb. 12, 2024, date of the exemption order, includes purchases made under Gran Tierra's current normal course issuer bid and any other normal course issuer bid in effect within such period, and is conditional upon, among other things, purchases being made in compliance with applicable U.S. rules, the TSX rules applicable to a normal course issuer bid and National Instrument 23-101 (Trading Rules), and at a price not higher than the market price at the time of purchase. The aggregate number of shares purchased by Gran Tierra over any exchange or market over the relevant 12-month period of a particular normal course issuer bid may not exceed 10 per cent of the public float as specified in Gran Tierra's notice accepted by the TSX in respect of the relevant normal course issuer bid, including the current bid announced on Oct. 31, 2023.
