## Exhibit 99.1

**Fitch Ratings Affirms Ecopetrol's National and International Credit Ratings**

Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) (the "Company" or "Ecopetrol") informs that Fitch Ratings, in its report dated October 30, 2025, reaffirmed the Company's global credit rating at 'BB+', along with its Negative Outlook, and its Standalone Credit Profile (SACP) at 'bbb-'. In addition, the national long- and short-term ratings were affirmed at 'AAA (col)' with a Stable Outlook and 'F1+(col)', respectively.

Fitch Ratings noted that the global rating of 'BB+' reflects Ecopetrol's strategic importance to Colombia, its ability to maintain a solid financial profile, and the stability of its operating metrics.

The assessment of these factors, along with other considerations included in the report, support an individual rating that falls within investment grade and stands one notch above the Company's global rating.

The full report issued by Fitch Ratings on October 30, 2025, detailing the rationale behind the ratings, can be accessed below:
