,001,456,652.00. With this acquisition, Petrobras increases its participation in the Atapu shared reservoir from 65.687% to 66.38%.

The amount to be paid by Petrobras in December 2025 is R$ 6.97 billion and the contracts will be signed by March 2026. The disbursement was already planned by the company, and although the volumes were not forecasted, they are within the margin of ±4% of the production curve projection in the Business Plan 2026-30.

This auction was supported by Law No. 15,164, dated July 14, 2025, which amended Law No. 12,351, dated December 22, 2010, authorizing the Union to dispose of its rights and obligations arising from production sharing agreements in non-conceded or non-shared areas in the pre-salt region.

Petrobras’ participation in the PPSA Non-Contracted Areas Auction is aligned with the company’s long-term strategy, reaffirmed in the Business Plan 2026-30, which foresees the replacement of its oil and gas reserves with economic and environmental resilience.
