Gran Tierra Energy Inc. (GTE) is asking stockholders to approve the sale of all equity interests in its Swiss subsidiary Gran Tierra Energy GmbH, which holds its Colombia and Ecuador operations, to Maurel & Prom Andina S.A.S. for total consideration of approximately $1.33 billion, consisting of cash, assumed debt, a pre‑payment facility and a 364‑day note. The transaction is being treated as a sale of substantially all of Gran Tierra’s property and assets under Delaware law and requires approval by a majority of outstanding common shares. Net proceeds are intended primarily to substantially eliminate remaining debt and fund strategic investments in the retained business in Canada and Azerbaijan, with the board continuing to evaluate other strategic alternatives. Completion also depends on regulatory approvals in Colombia and Ecuador, consents under certain debt and pre‑payment facilities, and other customary conditions. Gran Tierra will remain a public company focused on its retained assets, with new, more concentrated geographic and operational risk.
