Nomination and Governance Committee Report 2025 Summary Nomination and Governance Committee Report Presentation............................................... 3 Main indicators...........................................4 Highlights of the year................................. 5 Outlook for next year................................. 6 Final considerations.................................... 7 VALE \| Nomination and Governance Committee Report 2025 2 This report aims to present the actions carried out by the Committee in the period and its main perspectives for 2026. PRESENTATION Committee creation date The Committee was created on July 22, 2020, still as a Nomination Committee, an important milestone in the process of evolution of the Company's governance model, and on December 21, 2022 it was restructured as the Nomination and Governance Committee ("CIG"). This Report reflects the Committee's performance during the year 2025, in accordance with the governance assumptions in force during this period. Committee composition and structure The Committee, since May 16, 2025, is composed of Daniel André Stieler, as Coordinator, Marcelo Gasparino da Silva, Heloisa Belotti Bedicks and Franklin Lee Feder, as members. Daniel André Stieler Coordinator Marcelo Gasparino da Silva Committee member Heloisa Belotti Bedicks Committee member Franklin Lee Feder Committee member Committee main duties and responsibilities The Committee aims to advise the Board of Directors ("BoD") in the areas of its activities, in order to provide greater efficiency and quality to the decisions of the BoD. Its work is based on advising on the process of nominating members to the Board of Directors, in addition to the continuous evolution of Vale's Corporate Governance. In this regard, the Committee's main regimental attributions, among others, are to evaluate and recommend to the Board of Directors: i) Vale's internal policies and rules related to the nomination process of members of the Board of Directors, Advisory Committees and the Company's CEO; ii) the performance evaluation process of the Board of Directors and the Advisory Committees; iii) VALE \| Nomination and Governance Committee Report 2025 3 the strategy and guidelines for Vale's Corporate Governance documents, including Corporate Policies, Bylaws and Internal Regulations; iv) the perennial improvement of the Corporate Governance practices adopted by Vale; v) the compensation model and the budget of the Board of Directors and the Advisory Committees; and vi) the choice, compensation and evaluation of the Corporate Governance Officer. The Committee's performance during the first quarter of 2025 focused on the nomination process of Board members for the 2025-2027 term, who were elected by Vale's shareholders in April 2025. In addition, throughout 2025, the Committee contributed to the relevant maturation and consolidation of Vale's governance, with emphasis on the evolution of relevant Corporate Policies and the flow of information submitted to senior leadership, including the optimization of agendas and the dynamics of the meetings of the Board of Directors and its Committees, and it is also worth mentioning the active listening process to collect perceptions from members of the Executive Committee and investors on the occasion of the participation of Board members in non-deal roadshows, in addition to the consolidation of governance for emerging issues and review of the Internal Regulations of the Board of Directors and Committees. As a result of its governance practices, Vale, for the second consecutive year, achieved 100% adherence to the Brazilian Corporate Governance Code, according to the Governance Report published at the CVM. In this regard, the following stand out: (a) Board of Directors composed of 62% of independent directors (well above the provisions of the Novo Mercado Regulation – B3) and 23% of women; (b) its own and additional criteria for the independence of directors and overboarding (more restrictive than the concepts of the Novo Mercado Regulation in force and the proposal for its update presented in 2025); (c) existence of a Lead Independent Director (LID), in line with international best practices, to act as an alternative contact with shareholders, as provided for in the Bylaws; (d) Audit and Risk Committee composed entirely of independent directors; (e) annual holding of the Board's self-assessment process, aiming at identifying opportunities and planning actions for continuous evolution; and (f) Board with an Onboarding and Training Program, aiming to boost its integration into the business context, the Company's culture and the dynamics of its governance. MAIN INDICATORS Quantitative analysis of meetings The Committee met 15 times in 2025, with 9 ordinary meetings and 6 extraordinary meetings (same numbers as in 2024), representing the maintenance of the total number of meetings in relation to the previous year, especially considering the meetings held within the scope of the BoD recomposition process that took place in April 2025 for the 2025-2027 term. Average participation rate of Committee members The members of the Committee showed 100% attendance during the meetings in the 2025 fiscal year (considering the period from May to December 2025, relative to the current term). Average duration of Committee meetings Throughout 2025, the Committee met for 34 hours, with an average duration of 2h16min, being divided into 119 items on agendas, distributed in 84 informative themes and 35 deliberative themes. Quantitative analysis of the Committee's work plan and demands In 2025, the Committee's discussions covered 100% of the topics provided for in its annual work plan, having adjusted the frequency of discussion of some of them in favor of the Committee's focus and flexibility in prioritizing strategic topics, which was even considered as a driver for the construction of the work plan for the year 2026. In addition to its work plan, in 2025 88 demands were addressed in the period, and the Committee focused on several priority topics for the Company, not foreseen in its initial schedule, including: i) revisions of Corporate Policies and Internal Regulations of the Board of Directors and Committees, including for addressing emerging matters, such as climate and institutional issues, cybersecurity, health and safety (people, VALE \| Nomination and Governance Committee Report 2025 4 community and environment, dams and operational) and technology and innovation; ii) discussions about the revision of the Novo Mercado Regulation; iii) nominations of governance agents in Vale Group companies invoked by the Board of Directors; iv) Program of technical visits to the operations and institutional representation of the Board; v) evolution of the governance of subsidiaries, including Vale Base Metals; and vi) digital governance roadmap.
