Ecopetrol S.A. announced the tender offer consideration payable in connection with the previously announced cash tender offer (the "Offer") by Ecopetrol, which commenced on January 9, 2024, to purchase any and all of its outstanding 4.125% Notes due 2025 (the "Securities"), upon the terms and subject to the conditions set forth in Ecopetrol's Offer to Purchase, dated January 9, 2024 (as the same may be amended or supplemented from time to time, the "Offer to Purchase") and in the related Notice of Guaranteed Delivery (as it may be amended or supplemented fromtime to time, the "Notice of Guaranteed Delivery"), the terms and conditions of which remain unchanged. The Offer will expire, January 16, 2024, at 5:00 p.m., New York City time, unless extended (such date and time, as it may be extended, the "Expiration Time"). The Offer to Purchase contains detailed information regarding the manner in which the Total Consideration was calculated.

The following table sets forth the Total Consideration for the Securities. The Fixed Spread over the Reference Yield listed in the table below is based on the bid-side price of the Reference U.S.Treasury, as calculated by the Dealer Managers at 10:00 a.m., New York city time, as described in the Offer to Purchase. The Financing Condition means that the Company shall have priced and closed the Notes Offering on terms satisfactory to the Company and resulting in net cash proceeds sufficient to fund the Total Consideration with respect to the Securities validly tendered at or prior to the Expiration Time (reg regardless of actual amount of Securities tendered), plus accrued and unpaid interest on the purchased Securities from the last interest payment date to, but excluding, the Settlement Date.

The Offer is not an offer to sell or a solicitation of an offer to buy the New Notes. The complete terms and conditions of the Offer are set forth in the Offer to Purchase and in the related Notice of guaranteed Delivery, which holders are urged to read carefully before making any decision with respect to the Offer. The Offer is open to all registered holders of Securitie s. A beneficial owner of Securities that are held of record by a broker, dealer, commercial bank, trust company, or other nominee (each, a "Custodian") must instruct such Custodian to tender such Securities on the beneficial owner's behalf in a timely manner.

Beneficial owners should be aware that a Custodian may establish its own earlier deadline for participation in an Offer.
