Gran Tierra Energy (GTE) Corporate presentation summary

Transaction overview and strategic repositioning

• Completed $1.33 billion divestiture of Colombia and Ecuador assets, with $315 million in cash proceeds and all debt assumed by the buyer, resulting in a debt-free balance sheet and a pro-forma NAV of $12.49 per share, an 83% premium to the 20-day VWAP.

• Retained portfolio focuses on Canadian production (12-13 MBOEPD), 86 MMBOE 2P reserves, and significant contingent and prospective resources, with a fully undrawn C$75 million credit facility and $80 million in annual interest savings.

• Strategic rationale centers on concentrating capital on assets with the best risk-adjusted returns, returning capital to shareholders, and leveraging a simpler, lower-overhead structure.
