Ecopetrol S.A. Obtains Authorization to Enter into a Loan Agreement with International Banks for up to USD 530 Million

Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) (“Ecopetrol” or the “Company” and together with its subsidiaries, the “Ecopetrol Group”) announces that, through Resolution 3047 dated November 21, 2025 (the “Resolution”), the Ministry of Finance and Public Credit (“MHCP”) authorized the Company to enter into a loan agreement (the “Agreement”) for up to five hundred thirty million U.S. dollars (USD 530 million) with Banco Latinoamericano de Comercio Exterior, S.A. and Sumitomo Mitsui Banking Corporation (the “Lenders”). The credit facility will have a five (5)-year term starting from the contract signing date, with a bullet repayment at maturity, and a variable interest rate indexed to SOFR.

The proceeds of this transaction will be allocated to finance investments, in accordance with the Resolution issued by MHCP and Ecopetrol’s 2025 financing plan. The Company has complied with all required internal procedures and approvals to obtain the loan.

MHCP reviewed and approved the draft agreement, which includes customary borrower default events such as failure to make timely payment of principal and interest, any material impact on the borrower’s payment capacity, impairment of the integrity of the Company’s 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 debt, following the procedure set forth in the Agreement. Likewise, the draft agreement establishes Ecopetrol’s right to seek recourse against the Lenders if they fail to disburse funds under the agreed terms. Governing law is the laws of the State of New York.

The conditions obtained under this Agreement reaffirm the support and confidence of the international financial sector in the Ecopetrol Group’s strategy, amid a volatile market environment, where the Company continues to secure favorable financing terms.
