Ecopetrol advances acquisition of the Jemeiwaa Ka'I wind cluster in La Guajira with the purchase of a 49% interest in the JK1 and JK2 wind projects

BOGOTA, Colombia , May 20, 2026 /PRNewswire/ -- Ecopetrol S.A (BVC: ECOPETROL; NYSE: EC) announces that, pursuant to the Investment Framework Agreement entered into with AES Colombia & CIA SCA E.S.P. ("AES Colombia"), as disclosed on April 14, 2025, the conditions precedent and legal requirements for the acquisition of a 49% interest in two of the six projects comprising the wind cluster have been fulfilled.

The JK1 and JK2 projects are located in the Department of La Guajira and have an aggregate acquisition value of approximately USD 25.5 million. The projects have an assigned capacity of 259 MW and include a 35-kilometer transmission line connecting them to the collector substation. Ecopetrol and AES Colombia are working on the execution and operation framework for the development of the projects through a special purpose vehicle, in the form of an autonomous patrimony.

Following completion of construction and commencement of operations, the JK1 and JK2 projects are expected to generate approximately 1,100 GWh annually, representing approximately 12% of the Ecopetrol Group's average energy demand. The projects are expected to improve energy cost efficiency and strengthen operational reliability. In addition, they are anticipated to support the Group's energy transition strategy by delivering estimated decarbonization benefits of approximately 4.3 million tons of CO₂ equivalent.¹

In connection with this transaction, the conditions precedent for the remaining four projects comprising the Jemeiwaa Ka'I wind cluster remain pending. Once satisfied, those conditions will enable completion of the acquisition of the remaining portion of the 49% interest in the cluster.

Ecopetrol will timely inform the market of any further developments in this process, in accordance with applicable regulations, until the acquisition of the ownership interest in the cluster is completed.

Once all applicable conditions precedent and legal requirements for the closing of the transaction have been satisfied, Ecopetrol will disclose the relevant information in accordance with the applicable legal and regulatory framework through this same channel or through any other means required by applicable law or regulation.
