  • The company’s 2P reserves reached 258 MMBOE with a 2P reserve life index of 15 years

Gran Tierra Energy Inc (LSE:GTE) released its year-end reserves growth report for the period ended 31 December 2025 on 29 January 2026, outlining continuing expansion of the company’s resource base across South America, alongside defined valuation metrics that illustrate long-term asset value, contributing to recent market attention.

Gran Tierra’s 2025 year-end report underscores continued expansion of its reserves base, particularly in South America, where new discoveries and exploration success supported more than 100% replacement on both PDP and 2P measures.

Total 2P reserves were reported at 258 MMBOE at year-end, supporting a 2P reserve life index of 15 years — a key measure of the longevity of the company’s resource base. These results reaffirm the strategic importance of core producing assets such as Acordionero and Cohembi, which continue to deliver reliable performance and contribute to long reserve life.

Gran Tierra also reported significant volumes of contingent and prospective resources. The company holds approximately 74 MMBOE of unrisked 2C contingent resources and about 118 MMBOE of mean prospective resources, indicative of future development optionality and long-term growth potential.

Balance Sheet Position and Reserve Valuation in Focus

At the end of 2025, Gran Tierra’s net debt was approximately USD 657 million, reflecting senior notes partially offset by cash and equivalents of USD 83 million. These figures contribute to a conservative balance sheet position that supports ongoing operations and potential future investment.

Reserve valuation metrics also included after-tax NAV of USD 1.8 billion for 2P reserves, or USD 31.19 per share after tax, providing additional context for the company’s valuation framework. These metrics help frame how the company’s resource base contributes to long-term enterprise value.

Portfolio Diversification Supports Long-Term Optionality

While some natural gas reserves in Canada were reclassified to contingent resources due to lower forecasted gas prices, these volumes remain part of Gran Tierra’s long-term portfolio and may benefit from future price recoveries. The company’s diversification across three countries, five basins, and two continents supports a broad resource inventory and optionality in capital deployment as commodity markets evolve.

Investor Takeaway

Gran Tierra’s year-end update provides a snapshot of its reserve base, balance sheet position, and valuation metrics, offering investors additional context around the company’s long-term asset profile. The disclosure highlights reserve longevity, diversification, and development optionality rather than near-term performance drivers.
