Ecopetrol S.A. reported today its proven reserves of oil, condensate, and natural gas (1P reserves), including its share in proven reserves from subsidiaries, estimated based on the standards of the U.S. Securities and Exchange Commission (SEC). 99% of 1P reserves have been certified by three recognized, specialized, and independent firms: Ryder Scott Company, DeGolyer & MacNaughton, and GaffneyCline & Associates.

As of the end of 2025, Ecopetrol Group´s proven reserves totaled 1,944 billion barrels of oil equivalent (mmboe), representing a 2.7% increase compared to the reserves at the end of 2024.

Although the 2025 Brent reference price (USD 68.64/Bbl) decreased by 13.9% compared to the 2024 price (USD 79.69/Bbl)1, proven reserves contributions reached 300 mmboe and the reserves replacement ratio was 121%, demonstrating the Company’s effective management in line with its long–term sustainability and resilience strategy.

The reserves contributions were mainly the result of: (i) enhanced recovery projects with outstanding performance in the Castilla, Chichimene, and Akacias fields; (ii) better operational management in the Rubiales and La Cira–Infantas fields, focused on asset efficiency and value; and (iii) contracts with the ANH2.

These results represent the highest reserves replacement achieved in the last four years and reflect the capability and commitment of the Ecopetrol Group to generate value across its exploration, development, and production assets, thereby strengthening the sustainability of the Ecopetrol Group.
