Ecopetrol S.A. Strengthens Corporate Governance with Bylaws Amendment

Ecopetrol S.A., the largest integrated energy company in Colombia, has successfully registered amendments to its bylaws with the Bogotá Chamber of Commerce. This update follows the approval of changes during the General Shareholders' Meeting held on November 11, 2025, and is documented in Public Deed No. 2670, dated April 21, 2026, verified by the 32nd Notary Office of Bogotá D.C.

The decision to amend the bylaws signifies a strategic move by Ecopetrol to enhance its corporate governance framework, which is crucial for maintaining transparency and accountability within the organization. These changes were previously communicated to the market and are accessible for review via the Securities and Exchange Commission’s website.

Ecopetrol is recognized as a market leader in Colombia’s oil and gas production, accounting for over 60% of the country’s hydrocarbon output. The firm boasts a workforce exceeding 19,000 employees and holds significant positions in areas such as petrochemicals and gas distribution. It also plays a vital role in transportation, logistics, and refining sectors, underlining its integrated operational approach in the energy landscape.

A key aspect of Ecopetrol's growth strategy includes its recent acquisition of a 51.4% stake in Interconexión Eléctrica S.A. (ISA), allowing the company to expand into energy transmission. Through this partnership, Ecopetrol is involved in managing real-time systems and overseeing the concession for the coastal highway that links Barranquilla to Cartagena, further diversifying its portfolio beyond traditional petroleum and natural gas ventures.

Internationally, Ecopetrol has established a presence in vital basins across the Americas, including drilling and exploration activities in the Permian Basin and the Gulf of Mexico, as well as operations in Brazil and Mexico. Through ISA and its subsidiaries, the company has solidified its footprint in power transmission across several South American countries, including Brazil, Chile, Peru, and Bolivia, and has expanded into road concessions in Chile and the telecommunications sector.

The formalization of the bylaws amendment reflects Ecopetrol's commitment to robust corporate governance practices, which is particularly crucial in the current market climate marked by fluctuations in oil and gas prices. It also underscores the company's proactive measures in addressing potential risks and uncertainties that may influence its operations. Investors and stakeholders can find comfort in the transparency offered by this update, as well as the company's dedication to adhering to regulatory standards and best practices in governance.
