Petrobras announces adherence to the new economic subvention
—
Rio de Janeiro, June 2, 2026 – Petróleo Brasileiro S.A. – Petrobras informs that its Board of Directors, at a meeting held yesterday, approved the company’s adherence to the economic subvention granted to producers and importers of road-use diesel oil in Brazil, in the amount of R$ 1.12 per liter commercialized. This subvention was established by Provisional Measure (MP) 1,363, dated May 30, 2026, with the purpose of stabilizing price and supply to ensure the national availability of the fuel, in light of the supply shock resulting from the armed conflict in the Middle East.
Given the optional nature of the program and its potential benefit, this adherence is considered compatible with the company’s interests.
Petrobras also informs that, pursuant to MP 1,363, adherence to this new subvention requires the discontinuation of the qualification processes related to the economic subventions for road diesel oil previously established under MPs 1,340/2026 and 1,349/2026. This adherence, however, does not affect the right to receive economic subventions already owed to producers or importers under MPs 1,340 or 1,349.
Additionally, it should be noted that the adherence to the new subvention is complementary to the adherence previously authorized under MP 1,358, dated May 13, 2026.
Summary Table – Economic subvention related to road-use diesel oil:
| Provisional Measure (PM) | Economic Subvention | Period (2026) | Qualification |
| PM 1,340, of March 12 | Up to R$ 0.32/liter | From 03/12 to 12/31 |
Suspended
|
| PM 1,349, of April 7 |
Increased the subsidy of PM 1,340 to up to R$ 0.80/liter for producers and up to R$ 1.20/liter for importers |
From 04/07 to 05/31 |
Suspended
|
| PM 1,358, of May 13 |
R$ 0.35/liter (equivalent to PIS/Cofins) According to MF Ordinance No. 1,584, of May 29 |
From 06/01 to 07/31 |
Active
|
| PM 1,363, of May 30 | R$ 1.12/liter | From 06/01 to 12/31 | Active |
Petrobras emphasizes that it maintains its commercial strategy, considering its market share and the sustainable optimization of its refining assets and profitability, avoiding the transfer to domestic prices of the short-term volatility of international quotations and the BRL exchange rate.
This adherence preserves the company’s flexibility in implementing its commercial strategy. Petrobras remains committed to responsible, balanced, and transparent conduct.
