- Partner Participation Changes: Shell Brasil decreased to 22.650%; Petrogal Brasil decreased to 9.060%; Pré-Sal Petróleo (PPSA) increased to 0.833%.
- Financial Recognition: The filing does not provide specific revenue, profit, or cash flow figures for the period. It states that financial compensation amounts are currently being calculated.
- Liquidity Impact: Cash inflows related to the compensation are expected in Q1 2026.
Material Changes Versus Prior Period
The primary material change is the adjustment of ownership stakes in the Tupi Shared Reservoir following the first redetermination process. Petrobras' stake increased by approximately 0.24 percentage points. Consequently, the parties are committed to executing financial compensation for expenses incurred and revenues related to volumes produced up to the effective date, governed by Expenses and Volumes Equalization Agreements (AEGV).
