Petrobras, following up on the announcement made on July 23, 2025, informs that it has signed the Expenses and Volumes Equalization Agreement (AEGV) with PPSA (Pré-Sal Petróleo S.A.), resulting from the Production Individualization Agreement (AIP) for the Jubarte Pre-Salt Shared Reservoir.

The amount owed by Petrobras to PPSA is R$ 1.54 billion, which will be paid in a single installment by the end of October. Of this total, R$ 1.47 billion had already been provisioned in the financial statements for 2Q25, as disclosed in explanatory note 17.4 regarding Production Individualization Agreements.

The negotiation process for equalization between Petrobras (Jubarte Field) and the partners in the Argonauta Field – Shell Brasil Petróleo Ltda., Enauta Petróleo e Gás Ltda. (Brava), and ONGC Campos Ltda. – is ongoing and will be disclosed to the market upon its conclusion.

As disclosed on July 23, 2025, the approval of the AIP for the Jubarte Pre-Salt by Brazil’s National Agency of Petroleum, Natural Gas, and Biofuels (ANP) resulted in the definition of the proportional shares of each company in the shared reservoir, as follows:

• Petrobras: 97.250%
• Shell: 0.430%
• Brava: 0.198%
• ONGC: 0.232%
• Brazilian Union (represented by PPSA): 1.890%

This new configuration requires the negotiation of the AEGV to reconcile revenues derived from oil and natural gas production, incurred investment expenses, operating expenses, royalties, and special participation payments in proportion to the parties’ shares in the shared reservoir, in accordance with CNPE Resolution No. 8/2016 and ANP Resolution No. 867/2022. The period considered spans from the signing of the BC-60 Concession Agreement (Jubarte) on August 6, 1998, to July 31, 2025, the day prior to the effective date of the Jubarte Pre-Salt AIP.
