Rio de Janeiro, September 1, 2021

• Petróleo Brasileiro S.A. – Petrobras, following up on the release disclosed on 12/21/2018, informs that it has finalized the transfer of rights of its 10% interest in the Lapa field to TotalEnergies.

The operation, which also involves the assignment of the totality of the interest held by Petrobras Netherlands B.V. (PNBV) in Lapa Oil & Gas B.V., a company incorporated in the Netherlands, was concluded with the payment of US$ 49.4 million to Petrobras, already with the adjustments foreseen in the contract.

This transaction represents another step in the strategic partnership between Petrobras and TotalEnergies and is aligned with the strategy of portfolio optimization and the improvement of the Petrobras’ capital allocation, aiming at value maximization.

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

With the closing of this transaction, Petrobras will have no more stakes in Lapa, while TotalEnergies, which is already the field operator, will hold 45%. The other partners in the field are Shell Brasil Petróleo (30%) and Repsol Sinopec Brasil (25%).
