—

Rio de Janeiro, August 3, 2021 - Petróleo Brasileiro S.A. - Petrobras, following up on the release disclosed on July 01, 2021, informs the beginning of the binding phase regarding the sale of 100% of its interest in the PAR-T-175_R14, PAR-T-198_R12, and PAR-T-218_R12 Concessions, located onshore in the Paraná Basin.

Potential buyers qualified for this phase will receive a process letter with detailed instructions on the divestment process, including guidelines for due diligence and the submission of binding proposals.

This disclosure complies with the Petrobras' internal rules and with the provisions of the special procedure for assignment of rights to exploration, development and production of oil, natural gas and other fluid hydrocarbons, provided for in Decree 9,355/2018.

This transaction is in line with the company's portfolio optimization strategy and capital allocation improvement, increasingly concentrating its resources in world-class assets in deep and ultra-deep waters, where Petrobras has shown a great competitive differential over the years.
