Petrobras informs about shareholder remuneration
—

Rio de Janeiro, March 05, 2026 – Petróleo Brasileiro S.A. – Petrobras informs that its Board of Directors, in a meeting held today, authorized the submission to the Annual General Meeting (AGM), scheduled for April 16, 2026, of the proposal for the distribution of shareholder remuneration related to the fourth quarter of 2025 in the amount of R$ 8.1 billion. If approved by the AGM, considering the amounts advanced by the company throughout the year, duly adjusted by the Selic rate, shareholder remuneration related to the 2025 fiscal year will total R$ 41.2 billion.

It is worth noting that the adjustment by the Selic rate on the early dividends and interest on equity (JCP) related to fiscal year 2025, amounting to R$ 0.6 billion, was deducted from the total shareholder remuneration.

The proposed distribution is aligned with the current Shareholder Remuneration Policy (Policy), which establishes 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 shall distribute 45% of its free cash flow to shareholders. This distribution is consistent with the financial sustainability of the company.

Record date: For holders of Petrobras shares traded on B3, the record date will be April 22, 2026. Petrobras shares will trade ex-rights as of April 23, 2026.

Payment dates: The proceeds will be paid in two installments in May and June 2026, as follows:

Amount to be paid: R$ 0.62622908 per outstanding common and preferred share, distributed as follows:

It is important to highlight that the amounts of each installment will be updated by the variation of the Selic rate from December 31, 2025, until each payment date. Income tax will be levied on this monetary adjustment, in accordance with current legislation.

ADR holders: For holders of ADRs traded on the New York Stock Exchange (NYSE), the record date will be April 24, 2026, and the payments of the first and second installments will be made on May 28, 2026, and June 29, 2026, respectively.

The Shareholder Remuneration Policy is available on the company's website. (http://www.petrobras.com.br/ri).
