## Exhibit 99.1

![](ec202510236k_001.jpg)

**Ecopetrol S.A. has obtained authorization to execute a loan with local financial institutions for COP 700,000 million, under a committed credit line structure**

Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) ("Ecopetrol" or the "Company") hereby informs the market that, through Resolution 2691 dated October 21, 2025 (the "Resolution"), the Ministry of Finance and Public Credit ("MHCP") authorized the Company to enter into a domestic loan agreement for up to COP 700,000 million with Banco Davivienda, under a non-revolving committed credit line structure. The loan is expected to have a five-year term starting from the date of the first disbursement, with a bullet repayment at maturity, and interest accruing at a variable rate indexed to the IBR rate, in accordance with the terms previously agreed with the lender. The credit line may be drawn during the 12 months following the execution date of the loan.

The proceeds from this transaction are expected to be used for non-investment expenditures, in line with the Resolution and the Company's financing plan. The Company complied with all internal procedures and approvals required for the loan. The MHCP reviewed and authorized the terms of the draft agreement, which outlines standard borrower default events such as failure to pay principal and interest, potential impairment of the borrower's repayment capacity, issues affecting the integrity of its financial information, and breach of contractual obligations, among others. Should any of these events occur, the lenders would have the right to demand early repayment of the loan, pursuant to the procedures set forth in the agreement. Likewise, the draft agreement grants Ecopetrol the right to seek recourse against the lenders in the event of non-disbursement of the loan.

The terms secured for the committed credit line, including the lowest spread rate obtained by Ecopetrol in the local market, reaffirm the support and confidence of the domestic financial sector in Ecopetrol's strategy. This is particularly relevant in the current market, where, despite challenging conditions, the Company continues to achieve favorable financing terms. Moreover, it sends a positive signal to credit rating agencies, as the committed credit line provides a reliable and flexible source of liquidity that contributes to the Company's financial stability and strengthens its cash position.
