Given the geopolitical situation in the Middle East and its impact on international oil and oil products prices, as of March 2026, the Brazilian Federal Government granted economic subsidies to the trade of road-use diesel, LPG, and gasoline in Brazil, equalizing a portion of the costs of producers and importers, aimed at contributing to stabilize prices and supply of oil products.

Petrobras adhered to these programs, whereby authorized amounts and conditions for receiving subsidies are defined within specific legal and regulatory framework for each product and period.

Subsidy revenue is recognized when the eligible oil products are sold and delivered to customers. The following table presents subsidy revenue by fuel recognized in the six-month period ended June 30, 2026, including their legal instruments:

In the six-month period ended June 30, 2026, the Company recognized subsidy revenue of U$$ 2,227, net of Pis and Cofins. As of June 30, 2026, the balance of this subsidy was US$ 2,021.

In July 2026, the Company received additional US$ 844 relating to this program. The receipt of the remaining balance is awaiting documentation analysis by ANP.

The criteria for compensation of members of the Board of Directors and the Board Executive Officers is based on the guidelines established by the Secretariat of Management and Governance of the State-owned Companies (SEST) of the Ministry of Management and Innovation in Public Services, and by the Ministry of Mines and Energy. The total compensation is set out as follows:

In the six-month period ended June 30, 2026, expenses related to compensation of the board members and executive officers of Petrobras amounted to US$ 7.3 (US$ 6.5 for the same period of 2025).

The compensation of the Advisory Committees to the Board of Directors is separate from the fixed compensation set for the Board Members and, therefore, has not been classified under compensation of Petrobras’ key management personnel.

In accordance with Brazilian regulations applicable to companies controlled by the Brazilian Federal Government, Board members who are also members of the Statutory Audit Committees are only compensated with respect to their Audit Committee duties. The total compensation concerning these members was US$ 132 thousand for the six-month period ended June 30, 2026 (US$ 156 thousand with tax and social security costs). For the same period of 2025, the total compensation concerning these members was US$ 115 thousand (US$ 136 thousand with tax and social security costs).

On April 16, 2026, the Company’s Annual Shareholders’ Meeting set the threshold for the overall compensation for executive officers and board members at US$ 11, R$ 57.22 million, from April 2026 to March 2027 (US$ 8.3, R$ 47.57 million, from April 2025 to March 2026, as approved on April 25, 2024).
