Investor Verification Checklist
- Verify the 57% year-over-year increase in total proved reserves (588.1 MMboe) and the breakdown between developed (232.5 MMboe) and undeveloped (355.7 MMboe) reserves.
- Confirm the 605% total reserve replacement ratio and the 260% organic reserve replacement ratio.
- Review the production growth of 66% year-over-year for 2025, specifically the contribution from the La Amarga Chica acquisition and new well tie-ins.
- Assess the discounted future net cash flow valuation of $6,607 million based on the stated price assumptions ($64.0/bbl oil).
- Examine the details of the La Amarga Chica acquisition (139.2 MMboe at acquisition) and the Trafigura Agreement (6.1 MMboe) to understand the inorganic growth component.
