Ecopetrol S.A. Negotiates Acquisition of a Portfolio of up to 88.2 MWp in Solar Photovoltaic Projects in Colombia

BOGOTA, Colombia, Nov. 28, 2025 /PRNewswire/ -- Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) ("Ecopetrol" and together with its subsidiaries, the "Ecopetrol Group") announces that on November 28, 2025, it successfully concluded negotiations with Grenergy Renovables S.A. for the potential acquisition by Ecopetrol of seven (7) companies within its portfolio in Colombia, located across the departments of Córdoba (3), Cesar (2), Magdalena (1), and Sucre (1).

Each company owns the assets, licenses, agreements, and permits for a solar photovoltaic project with an estimated renewable energy generation capacity of up to ~12.6 MWp per project. The acquisition is subject to certain conditions precedent and other certain legal requirements.

Upon closing of the transactions, Ecopetrol would advance its decarbonization and energy transition goals by adding additional installed capacity toward its target of 900 MW of self-generated renewable energy. These initiatives are essential to complement its energy matrix in alignment with the 2040 Strategy, Energy that Transforms. Additionally, they would support low-emission energy generation under competitive conditions for Ecopetrol Group's self-consumption, reduce bilateral energy contract purchases, and mitigate exposure to spot market energy purchases.

Once conditions precedent and legal requirements for each transaction are met, Ecopetrol will disclose the relevant information, including the closing and final value of each transaction, through this same channel.

Ecopetrol is the largest company in Colombia and one of the main integrated energy companies in the American continent, with more than 19,000 employees. In Colombia, it is responsible for more than 60% of the hydrocarbon production of most transportation, logistics, and hydrocarbon refining systems, and it holds leading positions in the petrochemicals and gas distribution segments. With the acquisition of 51.4% of ISA's shares, the company participates in energy transmission, the management of real-time systems (XM), and the Barranquilla - Cartagena coastal highway concession. At the international level, Ecopetrol has a stake in strategic basins in the American continent, with Drilling and Exploration operations in the United States (Permian basin and the Gulf of Mexico), Brazil, and Mexico, and, through ISA and its subsidiaries, Ecopetrol holds leading positions in the power transmission business in Brazil, Chile, Peru, and Bolivia, road concessions in Chile, and the telecommunications sector.
