Petrobras announces that it has been notified by Brazil’s National Agency of Petroleum, Natural Gas and Biofuels (ANP) regarding the approval of the addendum to the Production Individualization Agreement (AIP) of the Tupi Shared Reservoir, located in the Santos Basin, which becomes effective as of today.

The Tupi Shared Reservoir comprises:

• The BM-S-11 Concession Contract (Tupi field), operated by Petrobras (65%), in partnership with Shell (25%) and Petrogal (10%);
• The Tupi South Block, under the Transfer of Rights Agreement (Tupi South field), operated by Petrobras, which holds 100% of the participation; and
• The Non-Contracted Area, owned by the Brazilian Federal Government, represented by Pré-Sal Petróleo – PPSA under the AIP, as provided for in Law 12,351/2010.

With the addendum, resulting from the completion of the first redetermination process of the Tupi Shared Reservoir, Petrobras’ participation in the Reservoir increases to 67.457%.

The table below shows the previous and new participation percentages for the parties:

As a result of the changes in participation shares, the companies are committed to carrying out financial compensation for the expenses incurred and revenues related to the volumes produced up to the effective date of this AIP addendum, in accordance with the applicable Expenses and Volumes Equalization Agreements (AEGV).

The amounts are currently being calculated by the parties, and the amount to be received by Petrobras will be recognized in the financial statements for 4Q25, with cash inflows expected in 1Q26.

It should be clarified that the Tupi AIP does not include the reservoir known as Iracema, which remains with the same participation shares as the BM-S-11 consortium.
