Disclaimer – Presentation of Oil & Gas Information

The information provided on this website regarding oil and gas operations, reserves, and metrics is for informational purposes only and may not provide all the details necessary for an in-depth evaluation. Readers should review the Company’s publicly filed documents and consult with financial, legal, and professional advisors before making investment or business decisions.

Barrel of oil equivalents (“BOEs”) are presented using a conversion ratio of six thousand cubic feet (“Mcf”) of natural gas to one barrel of oil. This ratio is based on energy equivalence and does not reflect economic value at the wellhead. As a result, BOEs may be misleading, particularly if used in isolation. Production figures are reported on a working interest (WI) basis (operating and non-operating) before royalty deductions, unless otherwise specified. Per BOE amounts are calculated based on WI sales before royalties.

References to formations where evidence of hydrocarbons has been encountered do not guarantee commercial recovery of hydrocarbons in any estimated quantity. Gran Tierra’s reported production is a mix of light, medium, and heavy crude oil, and its sales volumes often represent blends of more than one product type. Preliminary well test results and well log interpretations should not be relied upon as indicators of long-term performance or ultimate recovery unless confirmed through further analysis.

Definitions and Terms

• 1P, 2P, 3P: Represent different classifications of reserves: Proved, Proved plus Probable, and Proved plus Probable plus Possible reserves, respectively.
• Reserves: Quantities of oil, natural gas, and related substances recoverable from known accumulations under reasonable economic conditions.
• Reserve life index: Calculated as reserves in the referenced category divided by the referenced estimated production. Management uses this measure to determine how long the booked reserves will last at current production rates if no further reserves were added.

For further information regarding oil and gas definitions, refer to Canadian National Instrument 51-101 (“NI 51-101”), CSA Staff Notice 51-324, and the Canadian Oil and Gas Evaluation Handbook (“COGEH”).

Reserves Information

Unless otherwise indicated, all reserves values, future net revenue, and related metrics referenced on this website reflect values as of December 31, 2024, based on the GTE McDaniel December 31, 2024 Reserves Report, prepared by McDaniel & Associates Consultants. Additional information regarding reserves data can be found in Gran Tierra’s publicly filed Statement of Reserves Data and Other Oil and Gas Information on Form 51-101F1 at www.sedarplus.com.

Estimates of reserves are subject to various uncertainties and may not reflect actual recoverable quantities. Variations between estimated and actual reserves may be material, and reserve estimates do not necessarily represent fair market value. Future net revenue estimates are based on forecast prices and development costs but exclude indirect costs such as administrative expenses.

Oil and Gas Metrics

This website may contain oil and gas metrics such as free cash flow, reserve life index (RLI), net asset value per share (NAV), and reserves replacement. These metrics may not have standardized definitions and may not be comparable to similar measures used by other companies. Management uses these metrics to evaluate performance, but they are not reliable indicators of future performance. Readers should not rely solely on these metrics for investment decisions.

For further information and disclaimers on the above measures and metrics refer to the Appendix to our Corporate Presentation.
