The possibility to request the adoption of a multiple voting procedure shall be exercised by shareholders up to forty-eight (48) hours before the Meetings, i.e. until 1:00 p.m. of April 23, 2024, according to paragraph 1 of article 141 of Brazilian Corporation Law.

Under item II of Paragraphs 4 and 6 of Article 141 of Brazilian Corporation Law, preferred shareholders who intend to exercise the right to elect a member of the Board of Directors through separate voting must jointly represent, at least, a quorum of 10% (ten percent) of the share capital present at the Meeting and prove uninterrupted ownership of their shareholding since January 25, 2024.

The exercise of the voting right in case of stock lending will be borne by the borrower, except if otherwise provided for in the contract signed between the parties, in which case said contractual instrument must be made available during the accreditation phase for participation in the Meetings.

Despite the possibility of participating in-person or via Digital Platform, Petrobras recommends that shareholders adopt the Remote Voting Form.

The Company informs that the instructions provided in the Meetings Manual and the Remote Voting Form aim to help shareholders fill out the Remote Voting Form. Shareholders who choose to use the Remote Voting Form are solely and entirely responsible for filling it out correctly, regardless of how they have accessed it, either directly (on the websites of the Company or CVM), or indirectly (by sending the form to be filled out by custody agents, voting recommendation consulting firms hired by the shareholder, or the Company's bookkeeper institution).

The documents related to the matters to be resolved at the Annual and Extraordinary Shareholders' Meeting are available to shareholders on the websites of the Company (http://www.petrobras.com.br/ri) and Brazilian Securities and Exchange Commission - CVM (http://www.cvm.gov.br), according to CVM Resolution 81.
