Rio de Janeiro, August 07, 2025– A Petróleo Brasileiro S.A. – Petrobras, pursuant to CVM Resolution No. 44/21, informs that its Board of Directors, in a meeting held today, approved the payment of interim dividends and interest on equity in the amount of R$ 8.66 billion, equivalent to R$ 0.67192409 per outstanding common and preferred share, as an anticipation of the remuneration to shareholders, related to the fiscal year 2025, declared based on the balance sheet as of June 30, 2025.

The proposed payment is in line with the current Shareholder Remuneration Policy (Policy), which stipulates that, in the event of gross debt equal to or less than the maximum debt level defined in the current Strategic Plan, and subject to the other conditions of the Policy, Petrobras must distribute 45% of free cash flow to its shareholders. This distribution does not compromise the financial sustainability of the company.

The dividends will be paid in two installments in November and December 2025, as follows:

Amount to be paid: R$ 0.67192409 per outstanding common and preferred share, as follows:

(i) The first installment, in the amount to R$ 0.33596205 per outstanding common and preferred share, will be paid on November 21, 2025, entirely in the form of interest on equity.

(ii) The second installment, amounting to R$ 0.33596204 per outstanding common and preferred share, will be paid on December 22, 2025, with R$ 0.20092175 in the form of dividends and R$ 0.13504029 in the form of interest on equity.

Record date: August 21, 2025 for holders of Petrobras shares traded on B3 and record date on August 25, 2025 for holders of ADRs traded on the New York Stock Exchange (NYSE). Petrobras shares will be traded ex-rights on B3 as of August 22, 2025.

Payment dates: For holders of Petrobras shares traded on B3, the first installment will be paid on November 21, 2025, and the second installment on December 22, 2025. ADR holders will receive payments starting from December 01, 2025, and December 30, 2025, respectively.

It is important to note that these payments will be deducted from the remuneration to shareholders to be approved at the 2026 Annual General Meeting relating to the 2025 fiscal year, and their amounts will be adjusted by the Selic rate from the date of payment of each installment until the end of the current fiscal year for the purposes of calculating the deduction.
