Business Context and Reporting Period
This Form 6-K, filed on April 2, 2026, by Petrobras (Petróleo Brasileiro S.A.), reports on the completion of financial settlements related to the first redetermination of the Tupi Shared Reservoir in the Santos Basin. The filing references a prior announcement from December 1, 2025, regarding the approval of the Fourth Addendum to the Production Individualization Agreement (AIP).
Key Financial Metrics
- Cash Inflows: Approximately R$ 3 billion received from consortium partners (Shell and Petrogal) on March 31, 2026.
- Cash Outflows: Approximately R$ 600 million paid to the Federal Government (represented by Pré-Sal Petróleo - PPSA) on March 31, 2026.
- Accounting Recognition: These amounts were recognized in the financial statements for the fourth quarter of 2025 (4Q25).
- Participation Change: Petrobras' share in the Tupi Shared Reservoir increased from 67.216% to 67.457% effective December 1, 2025.
Material Changes
The primary material change is the adjustment of participation shares in the Tupi Shared Reservoir following the AIP addendum. Consequently, Petrobras received net compensation from partners to equalize expenses and revenues incurred prior to the effective date. The Federal Government's share increased from 0.551% to 0.833%, while Shell and Petrogal saw their respective shares decrease.
Outlook, Risks, and Contingencies
The filing includes a standard forward-looking statement disclaimer, noting that forecasts reflect management expectations and involve risks and uncertainties. The document clarifies that the Tupi AIP does not include the Iracema reservoir, which retains its original participation shares under the BM-S-11 consortium agreement. No specific future guidance or new risk factors beyond the standard disclaimer are provided in this text.
Investor Verification Checklist
- Verify the impact of the R$ 2.4 billion net cash inflow (R$ 3 billion received minus R$ 600 million paid) on the 4Q25 and full-year 2025 financial statements.
- Confirm the updated ownership percentages for the Tupi Shared Reservoir in subsequent quarterly reports.
- Review the distinction between the Tupi Shared Reservoir and the Iracema reservoir to ensure accurate asset valuation.
