—

Rio de Janeiro, June 14, 2021 - Petróleo Brasileiro S.A. – Petrobras, following up on the release disclosed on 08/05/2020, informs that it has today finalized the sale of its 50% interest in the Dó-Ré-Mi onshore field, located in the Sergipe-Alagoas Basin, in the state of Sergipe, to the company Centro-Oeste Óleo e Gás Ltda.

After fulfilling the previous conditions, the operation was concluded for the sale price of US$37.6 thousand, which had already been paid to Petrobras on the date the purchase and sale agreement was signed, on 08/05/2020.

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

This trasaction is aligned with the strategy of portfolio optimization and the improvement of the company's capital allocation, increasingly concentrating its resources on world-class assets in deep and ultra-deep waters, where Petrobras has demonstrated great competitive edge along the years.
