MANUAL OF GENERAL SHAREHOLDERS’ MEETING 2026 23 Guidelines for Participation 3. ELECTION FOR THE BOARD OF DIRECTORS VIA DISTANCE VOTING BALLOT The candidates nominated by the controlling shareholder and the candidates nominated by minority shareholders, in accordance with the terms and deadlines established in CVM Resolution 81, will be included in the Distance Voting Ballot and will be disclosed by Petrobras through a notice to the market. It should be noted that, according to Article 37, item I of CVM Resolution 81, shareholders may include candidates for the Board of Directors and the Fiscal Council in the Distance Voting Ballot, provided that they meet the minimum percentage requirements for a certain class of shares as established in Annex N of the CVM Resolution 81. If the Company receives a nomination for a candidate to the Board of Directors or to the Fiscal Council after the deadline of 25 (twenty-five) days prior to the scheduled date of the Meeting, these nominations will not be included in the Ballot. However, such nominations will be disclosed by Petrobras through a notice to the market, and these nominees may become candidates, subject to the Company's governance rules. Shareholders are reminded that holders of common shares who use their shares to vote in the separate election for a member of the Board of Directors may not use those shares to vote in the general election of members of the Board of Directors, whether in the slate election or in the cumulative voting process (if adopted). Instructions of the Distance Voting Ballot The election of the Board of Directors in the Distance Voting Ballot is structured as follows: a) Separate election of nominees by holders of preferred shares Items 5 and 6 b) Election by the slate system (if the cumulative voting process is not adopted) Item 7: shareholders may vote (“APPROVE,” “REJECT,” or “ABSTAIN”) regarding the slate listed in the Ballot. Item 8: shareholders who approved the slate in item 7 must indicate whether they wish to maintain their vote for the chosen slate in the event of any changes to the candidates comprising the slate in the Ballot. A “YES” vote on this item 8 means that the shareholder will continue to vote for the slate, even if one or more candidate names are changed. c) Request for adoption of cumulative voting process by the shareholder Item 11: shareholders may vote (“YES,” “NO,” or “ABSTAIN”) regarding the request for the adoption of cumulative voting process, in accordance with the “Instructions for Cumulative Voting” section below. d) Election through the cumulative voting process, if adopted The slate election becomes void, and 8 (eight) positions on the Board will be disputed, allowing both candidates nominated by the controlling shareholder and those nominated by minority shareholders to receive individual votes. Item 12: shareholders must indicate whether they intend to distribute their votes equally among all candidates listed in the Ballot and may vote in item 13, in accordance with the “Instructions for Cumulative Voting” section below. Item 13: shareholders may indicate the candidates to whom they wish to distribute their votes equally or assign specific percentages individually, in accordance with the “Instructions for Cumulative Voting” section below. MANUAL OF GENERAL SHAREHOLDERS’ MEETING 2026 24 Guidelines for Participation Instructions for Cumulative Voting Regarding cumulative voting process via Distance Voting Ballot, it is worth noting that: − The election of the Board of Directors members generally takes place through the slate system (items 7 and 8), however, shareholders who wish may request the adoption of cumulative voting process by approving item 11 in the Ballot (“YES”), allowing votes to be allocated individually among the candidates. If shareholders vote “NO” or “ABSTAIN,” their shares will not be counted for the purpose of requesting cumulative voting. − If the minimum percentage of participation in the share capital of 5% (five percent) of the voting capital required to request the adoption of cumulative voting for elections is reached, the cumulative voting process will be adopted. In this case, the slate voting for candidates nominated by the controlling shareholder will become void (item 7), and the election will take place through the allocation of votes to each candidate (items 12 and 13). Both candidates nominated by the controlling shareholder and those nominated by minority shareholders may receive individual votes. − Thus, shareholders who wish their votes to be counted in the election of the Board of Directors members must allocate their votes (at their discretion) in items 12 and 13, even if they have voted against the adoption of cumulative voting in item 11. Otherwise, the shareholder will not participate in the election of the Board of Directors members through the cumulative voting process. − Regarding items 12 and 13, which are only considered if the cumulative voting process is adopted, shareholders may: (i) opt to distribute their votes equally only among selected candidates by voting “YES” in item 12 and specifying all the candidates to whom they wish to allocate their votes proportionally in item 13; (ii) opt to assign a specific percentage of their votes to their preferred candidates by voting “NO” in item 12 and using item 13 to indicate their chosen candidates and allocate the respective percentages to each selected candidate. If the sum of the indicated percentages is higher or lower than 100%, the votes will be disregarded. (iii) opt to vote “ABSTAIN” in item 12, in which case their votes will not participate in the election of the Board of Directors members through the cumulative voting process. Shareholders voting through third-party systems must verify whether these systems are compatible with the entry of percentage numbers for each candidate. If not, shareholders should inquire with the third-party responsible for the system about the procedure to be adopted to ensure that the numerical percentages are properly processed. We clarify that, pursuant to Articles 141, paragraph 7, of the Brazilian Corporations Law and 19, item III, of the Company’s Bylaws, whenever, cumulatively, the election of the Board of Directors is carried out through the cumulative voting system and the holders of common or preferred shares exercise the prerogative to elect a Director, the Brazilian Federal Government shall be guaranteed the right to elect a number of Directors equal to those elected by the other shareholders and by the employees, plus one (1), regardless of the number of Directors established in Article 18 of the Company’s Bylaws. MANUAL OF GENERAL SHAREHOLDERS’ MEETING 2026 25 Guidelines for Participation All necessary information for completing the Ballot regarding the items related to the election of the Board of Directors members is detailed in the Distance Voting Ballot, which is available on the websites of Petrobras (http://www.petrobras.com.br/ir) and CVM (http://www.cvm.gov.br). To clarify any questions or obtain more information on how to exercise their vote via Distance Voting Ballot, shareholders should contact the authorized service provider or the Investor Relations department of Petrobras, via email: assembleias@petrobras.com.br.
