**Ecopetrol Group Releases Its First Financial Sustainability Report, Incorporating Reference Elements from the International Sustainability Standards Board (ISSB) Framework**

Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) announces that it has published its first 2024 Financial Sustainability Report, in line with its commitment to transparency, sustainable value creation, and a fair and equitable energy transition for the country.

This document marks a milestone in the evolution of sustainability disclosure practices by consolidating the content previously presented separately under the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and the metrics of the Sustainability Accounting Standards Board (SASB) into a single report, incorporating reference elements from the International Sustainability Standards Board ("<u>ISSB</u>") framework.

This unified report has been implemented in response to the need to simplify, standardize, and enhance the value of sustainability information disclosed to the market. It is structured around the Ecopetrol's pillars of governance, strategy, risk and opportunity management, metrics, and targets.

The full report is available at the following link:
