Petrobras informs about assignment of minority stake in Brentech Energia S.A.

-

Rio de Janeiro, May 29, 2024 - Petróleo Brasileiro S.A. - Petrobras informs that today it signed a contract for the assignment of its entire 30% (thirty percent) stake in Brentech Energia S.A. (Brentech) to Enegen Participações Ltda (Enegen), Petrobras' partner in Brentech and holder of a 70% (seventy percent) stake in the company.

The transaction closed with the signing of the share purchase agreement, with no precedent conditions to be met, for the sum of R$10.6 million, paid in full on the same date.

The transaction is in line with Petrobras' strategy of decarbonizing its operations, optimizing its thermoelectric portfolio and prioritizing investments in highly efficient natural gas thermoelectric plants. As Goiânia II UTE is powered by diesel oil and has no synergies with our activities, the company does not adhere to Petrobras' strategy, which seeks integration and migration to a portfolio with a lower carbon footprint.

As it is a minority shareholder, Brentech does not have any Petrobras employees in the operation of the thermal plant.

This disclosure is in accordance with Petrobras' internal rules and applicable legislation.

About Brentech

Brentech is made up of a single asset - the Goiânia II UTE. Located in Aparecida de Goiânia (GO), this UTE uses diesel motor-generators, with a total installed capacity of 145 MW. The unit went into commercial operation on 01/17/2009 and its energy sales contracts in the regulated environment ended on 12/31/2023, and it is currently in the process of being demobilized.
