Ecopetrol Reports Results of Bondholders' Meetings for Domestic Public Debt Bonds Held at First Call

BOGOTÁ, Colombia, Aug. 18, 2026 /PRNewswire/ -- Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) (the "Company" or "Ecopetrol") hereby reports that, on August 18, 2026, meetings of the holders of the Company's domestic bonds issued in 2010 and in 2013 were convened and held at first call.

The meetings were called by the respective bondholders' representatives, Alianza Valores Fiduciaria S.A. and Itaú Fiduciaria Colombia S.A., pursuant to a notice of meeting published on August 6, 2026, in a newspaper of broad national circulation.

At the meeting of bondholders of the 2010 issuance, convened by Alianza Valores Fiduciaria S.A. and held today at 2:00 p.m. (Bogotá, D.C. time), no quorum was verified.

At the meeting of bondholders of the 2013 issuance, convened by Itaú Fiduciaria Colombia S.A. and held today at 3:30 p.m. (Bogotá, D.C. time), a quorum representing 15.33% of the outstanding principal amount of such issuance was verified.

Under Article 6.4.1.1.22 of Colombian Decree 2555 of 2010, approval of a merger proposal at a first-call meeting requires the affirmative vote of a plurality representing both (i) the numerical majority of bondholders present at the meeting and (ii) at least eighty percent (80%) of the outstanding principal amount of the relevant issuance.

Because the requisite majorities were not obtained at either meeting, a second-call meeting will be required for the holders of each of the two outstanding issuances. Notice of the second-call meetings will be published in a newspaper of broad national circulation in the coming days, and the Company will provide further updates as appropriate.
