Why It Matters
This filing gives investors updated, independently validated figures on Gran Tierra’s reserve base, recent production growth and a market‑value proxy (NPV10) for the company’s proved reserves. Key takeaways for investors: proved reserves remain material (≈111.6 MMBOE) while year‑over‑year reserve categories declined (proved down 17% from 2024), production and sales volumes rose sharply in 2025, and NPV10 after tax ($936M) provides a standardized snapshot of discounted future cash flows.
