The Brazilian subsidiary, Ecopetrol Investimentos do Brasil LTDA, filed the revised offer documents with the B3 Securities Exchange after receiving specific directives from the CVM in Official Letter No. 160/2026/CVM/SRE/GER-1. This filing reactivates the acquisition process for 116,110,717 common shares, which would grant Ecopetrol a controlling interest in the firm.

Investors have until August 5, 2026, to respond to the offer, with an auction scheduled for that date. The transaction remains contingent on the satisfaction of regulatory requirements and specific conditions precedent detailed in the B3 filing. Ecopetrol, which already maintains significant operations across the Permian basin, the Gulf of Mexico, and power transmission sectors in South America, intends to release the final results of the tender once the auction concludes.
