Ecopetrol's "New Era": The Company Announces Pricing of US$2.0 Billion in International Bonds to Optimize Its Debt Profile

BOGOTA, Colombia, Nov. 10, 2026 /PRNewswire/ -- Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) announces that, it has successfully priced an SEC-registered offering of US$2.0 billion 7.875% Notes due 2034 (the "Notes") with strong demand received from both domestic and international investors which reinforces market confidence in Ecopetrol's renewal and strategic transformation. The peak orderbook was approximately US$6.93 billion, or approximately 3.5 times the principal amount offered, from more than 235 investors in the United States, Europe, Asia and Latin America.

The strength and diversification of investor demand enabled Ecopetrol to achieve the lowest spread relative to the Republic of Colombia in an international debt offering over the last five years, underscoring the Company's ability to access global capital markets on competitive terms. Settlement is expected to occur on November 12, 2026, subject to customary closing conditions.

The Company intends to use the net proceeds from the offering (i) to fund the redemption of US$810 million aggregate principal amount of its outstanding 8.625% Notes due 2029 (the "2029 Notes") and (ii) to repay in full the short-term acquisition financing used to fund the Company's acquisition of an equity interest in Brava Energia S.A. on August 17, 2026, in each case as described in the prospectus supplement.

Through this transaction, the new management team of the Ecopetrol Group reinforces its proactive debt management strategy, as the operation replaces existing liabilities and does not increase the Company's overall indebtedness. In addition, it reduces near-term debt maturities, mitigates refinancing risk, and preserves the Company's liquidity position and financial flexibility.

The key terms of the offering were as follows:

The redemption of the 2029 notes is scheduled to occur on November 19, 2026. The final size of the transaction will be determined and communicated on that date.

Additional information regarding the terms and conditions of these transactions is available in the documents filed with the U.S. Securities and Exchange Commission (SEC), which investors are encouraged to review: https://www.sec.gov/Archives/edgar/data/1444406/000110465926124228/0001104659-26-124228-index.htm.

The transaction was authorized by the Colombian Ministry of Finance and Public Credit pursuant to Resolution No. 2595 dated November 9, 2026.
