Gran Tierra Energy Inc. Announces Approval of Norm

CALGARY, ALBERTA--(Marketwired - Feb. 6, 2017) - Gran Tierra Energy Inc. ("Gran Tierra") (NYSE MKT:GTE)(TSX:GTE) , a company focused on oil and gas exploration and production in Colombia today announces that it has received approval from the Toronto Stock Exchange (" TSX ") to implement its previously announced normal course issuer bid (the " Bid ") through the facilities of the TSX, the NYSE MKT and eligible alternative trading platforms in Canada and the United States. Pursuant to the Bid, Gran Tierra is able to purchase for cancellation up to 5% of its issued and outstanding shares of common stock (the " Shares ") for a one year period at prevailing market prices. The brokerage firm conducting the Bid on behalf of Gran Tierra is GMP FirstEnergy, with respect to purchases made on the TSX, and Griffiths McBurney Corp., with respect to purchases made on the NYSE MKT.

Under the Bid, Gran Tierra may repurchase for cancellation up to 19,540,359 Shares. This represents approximately 5% of its 390,807,191 issued and outstanding Shares as of January 27, 2017. These purchases will be made in accordance with applicable regulations over a maximum period of one year beginning on February 8, 2017 and ending on February 7, 2018. The average daily trading volume of the Shares over the six calendar months prior to the date hereof was 1,214,973. Accordingly, Gran Tierra is entitled to purchase, on any trading day, up to 303,743 Shares. The consideration that Gran Tierra will pay for any Shares acquired by it under the Bid will be paid in cash at the market price of such Shares at the time of acquisition.

The Management of Gran Tierra believes that the Shares, at times, have been trading in a price range which does not adequately reflect their value in relation to Gran Tierra's current operations, growth prospects and financial position. At such times, the purchase of Shares for cancellation may be advantageous to stockholders by increasing the value of the remaining Shares.
