—

Rio de Janeiro, December 06, 2021 - Petróleo Brasileiro S.A. – Petrobras, following up on the release disclosed on 02/24/2021, informs that it concluded today the sale of its total stake in nine onshore exploration and production fields, jointly called Miranga Cluster, located in the state of Bahia, to SPE Miranga S.A., a wholly owned subsidiary of PetroRecôncavo S.A. (PetroRecôncavo).

After compliance with the preceding conditions, the transaction was concluded with the payment of US$ 47.7 million to Petrobras, already with the adjustments provided for in the contract. The amount received at closing is in addition to the US$ 11 million paid to Petrobras when the sale contract was signed. The company will still receive the following installments, subject to adjustments: (i) US$ 80.1 million that will be paid in installments over twelve, twenty-four and thirty-six months; and (ii) up to US$ 85 million of contingent payments related to future oil prices.

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

This transaction is aligned with the company's strategy of portfolio management and capital allocation improvement, aiming to maximize value and provide greater return to society.
