INTERNA \ Força de Trabalho 3rd Quarter 2025 ― TAX REPORT INTERNA \ Força de Trabalho 22,9 FEDERAL + GOV. TAKE R$ 114.8 billion STATES R$ 83.3 billion MUNICIPALITIES R$ 1.5 billion R$ 199.6 billion PAID FROM JANUARY TO SEPTEMBER 2025 Petrobras reported a contribution of R$ 199.6 billion to the Government from January to September 2025. This amount includes R$ 132.3 billion in taxes from its own operations, R$ 46.9 billion in Government Take (Gov. Take), and R$ 20.4 billion in taxes withheld from third parties. In the year-to-date through the third quarter of 2025, Petrobras paid an amount of R$ 67.9 billion in federal taxes, which, together with R$ 46.9 billion in Government Take, this totals R$ 114.8 billion allocated to the federal government. Part of this amount is transferred to states and municipalities according to the current legislation. This value represents approximately 5.5% of total federal tax collection. Cumulative collections up to September 2025 remained stable compared to the same period of the previous year. In terms of state tax collections, Petrobras disbursed R$ 83.3 billion, representing approximately 13.6% of the total ICMS (VAT) collected by states. This reflects a 7.6% increase compared to the same period in 2024, that is mainly justified by the increase in sales of products (gasoline, diesel, and LPG) subject to the ICMS single-phase taxation. Municipal taxes amounted to R$ 1.5 billion for the period. The amount paid to municipalities is primarily distributed among ISS (Service Tax) towed by Petrobras, taxes withheld from third parties (substitute taxpayer), and IPTU (Urban Property Tax). This Tax Report details the cash outflows made by Petrobras for the payment of taxes and government take in the first nine months of 2025. The information follows the cash basis criterion and should be read together with the 2024 Tax Report, which presents the Company´s compliance aspects, tax risk management, and tax policy, including its principles and guidelines, as well as other information about our role as one of the largest taxpayers in Brazil. 2024 2025 199.6, 222.2, Collection Comparison – January to September (R$ Billions) Federal States Municipalities Gov.
