The amount to be paid by Petrobras in December 2025 is R$ 6.97 billion, and the contracts will be signed by March 2026. This disbursement was already planned by the company, and the volumes, although not initially projected, are within the +-4% margin of the projected production curve in the 2026-30 Business Plan.
This auction was supported by Law No. 15,164, of July 14, 2025, which amended Law No. 12,351, of December 22, 2010, authorizing the Union to sell its rights and obligations arising from production individualization agreements in non-granted or non-shared areas in the pre-salt area.
Petrobras' participation in the PPSA Uncontracted Areas Auction is aligned with the company's long-term strategy, reaffirmed in the 2026-30 Business Plan, which foresees the replenishment of its oil and gas reserves with economic and environmental resilience.
