## Exhibit 99.1

**Statement on Decision by the Attorney General's Office**

Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) reports that the Attorney General's Office, as part of an investigation into Ecopetrol's President Ricardo Roa, has decided to bring charges against him for his alleged responsibility for the crime of influence peddling by a public servant. This proceeding was held before the 35th Court of Guarantees of Bogotá.

Under Colombian law, the indictment is an act of communication that formally links Mr. Ricardo Roa to the criminal proceedings, discloses the facts under investigation and their legal consequences, and activates his right to defense. This proceeding does not amount to a conviction or a decision on the merits and does not undermine Mr. Ricardo Roa's presumption of innocence.

The Board of Directors respects Ricardo Roa's presumption of innocence and his right to due process. At a plenary meeting held on March 11, 2026, the Board of Directors determined that, in compliance with its fiduciary duty under Law 222 of 1995, Law 964 of 2005, and the Code of Good Governance, it plans to continue to act in accordance with due diligence and an established protocol. This protocol provides for an internal investigation and evaluation of the allegations.

The Board of Directors has been informed by management and supported by national and international firms. The Board of Directors plans to continue to deliberate to adopt a formal decision on the compatibility of Mr. Ricardo Roa's continuity with Ecopetrol's regulatory obligations, in accordance with Board of Directors' duties.

The Board of Directors will continue to closely and judiciously monitor the financial

information in order to analyze it and take corrective measures to address the impact that

the President's situation could have on the company's securities.

The Board of Directors is committed to ensuring the confidence of investors and stakeholders, as well as the financial sustainability, values, and governance of Ecopetrol.
