No entanto, dado que não foi avaliado à luz do Processo de Indicação formal da Vale, nos termos de sua governança, o CA, por maioria, entendeu por não se posicionar a respeito.

Attn.: Board of Directors Ref.: Request to call an Extraordinary General Meeting Dear Sirs, Caixa de Previdência dos Funcionários do Banco do Brasil – Previ, in its capacity as a shareholder of Vale S.A. ("Vale" or the "Company"), holder of 7.01% of the Company's share capital, pursuant to Articles 121, 122, item II, 123, sole paragraph, (c), of Law No. 6,404/1976 (the "Brazilian Corporate Law") and CVM Resolution No. 70/2022, hereby respectfully requests that an Extraordinary General Meeting be called to deliberate on the following matters: (i) the removal of Mr. Daniel André Stieler from the position of member of the Board of Directors; (ii) the appointment of Mr. José Mauricio Pereira Coelho as a full member of the Board of Directors, to complete the current term of office; and, if the matter set forth in item (i) is approved, (iii) the election of the Chair of the Board of Directors. This request is based on the need to improve the Company's corporate governance, as well as to strategically align the actions of the Board of Directors with the creation of sustainable long-term value, also considering the Critical Competencies Matrix of the Board of Directors. On this same occasion, we declare our support for the nomination of Mr. Manuel Lino Silva de Sousa Oliveira for the position of Chair of Vale's Board of Directors, as we understand that the potential conduct of such office will contribute positively to: • strengthening governance practices; • improving strategic management; • alignment with the interests of shareholders and stakeholders. In view of the above, the following is requested: 1. Formal receipt of this request; 2. Adoption of the necessary measures for the calling of the Extraordinary General Meeting, pursuant to the applicable legislation, the Company's Bylaws and internal rules, including the Officers Policy; 3. Inclusion of the matters described above in the agenda of the meeting. In compliance with Articles 3 and 7 of Annex K to CVM Resolution No. 80/2022 ("CVM Resolution 80") and Article 11, item I, of CVM Resolution No. 81/2022, Previ encloses with this request: (i) a statement by Mr. José Mauricio Pereira Coelho that he meets the requirements provided for in Article 147 of the Brazilian Corporate Law to hold office; (ii) the candidate's résumé, containing his qualifications; (iii) the information regarding the candidate provided for in items 7.3 to 7.6 of the Reference Form; and (iv) his statement of compliance with the independence criteria set forth in Annex K to CVM Resolution 80, in the Novo Mercado Regulation and in the Company's Bylaws. No further matters for the moment, we renew our highest regards. Rio de Janeiro, 11 June 2026 Adriana Duarte Chagastelles Director of Participations [20:25, 19/06/2026] Daniel Stieler: “I am not here to defend a personal position. I am here to defend the importance of decisions based on facts, governance, and the best interests of the Company.” This statement may be repeated several times throughout the defense. The situation goes beyond a simple “change in leadership” and may evolve into a potential scenario involving Abuse of Rights and Breach of Disclosure Duties, should the formal justifications prove to be materially inconsistent with the factual reality. As a preliminary matter, it is important to clarify that Previ’s request for removal, coupled with the nomination of another director, is not supported by the shareholding stake it currently holds. The other shareholders with ownership stakes equivalent to Previ’s each have only one nominated member. Furthermore, my independent status has already been formally declared since the last Shareholders’ Meeting. 1. The Conflict Between the Ad Nutum Right and Material Truth Although Article 140 of Brazilian Corporate Law (Law No. 6,404/76) grants shareholders the right to remove directors at any time and without cause (ad nutum), such right is not absolute when exercised within the framework of a publicly held company with dispersed ownership (corporation). If Previ presents specific justifications—such as the need to strengthen corporate governance, strategic alignment of the Board of Directors with the creation of sustainable long-term value, consideration of the Board’s Critical Competencies Matrix, enhancement of governance practices, improvement of strategic management, alignment with the interests of shareholders and stakeholders, or a purported “need for strategic improvement”—it links the ethical and, to some extent, legal validity of the act to those stated reasons. Such allegations may be challenged by positive performance indicators, the absence of proceedings, and a constructive relationship with the Board, thereby rendering the official justification an administrative misrepresentation of facts. 2. Abuse of Voting Rights (Article 115 of the Brazilian Corporate Law – Law No. 6,404/1976) The assessment of leadership should be grounded in objective indicators. The Company has demonstrated consistent progress in operational efficiency, capital discipline, shareholder returns, and significant advancements in sustainability and safety. Naturally, there are always opportunities for improvement. No organization is ever fully complete. The key issue is whether a leadership transition at this point would create greater value than the risks inherently associated with such a transition during a favorable operational and strategic cycle. Shareholders must exercise their voting rights in the best interests of the Company. A request to remove a Chairman of the Board that is not supported by facts may constitute a potential misuse of power. Harm to the Corporate Interest: Removing an effective leader under false pretenses may be interpreted as an act intended to serve the particular interests of a shareholder to the detriment of the Company’s interests, thereby constituting an abuse of voting rights. 3. Disclosure Responsibility (CVM Resolution No. 80/2022) The Brazilian Securities and Exchange Commission (CVM) requires that information disclosed to the market be truthful, complete, consistent, and not misleading to investors. Accordingly, the Company’s officers and the Company itself have a responsibility to ensure that the information disclosed in the Notice of Call for the Extraordinary Shareholders’ Meeting is accurate and reliable, avoiding the dissemination of justifications that do not reflect the Company’s actual performance indicators and institutional assessments. The uncritical reproduction of an isolated statement by a particular shareholder does not exempt the Company from its duty to provide accurate information, as required in the domestic and international markets in which it operates. Such an anomaly could expose the Company to administrative inquiries by the CVM and even judicial measures brought by other shareholders who may consider themselves harmed by artificially created instability. 4. The Governance Paradox My actions have always been subject to the control and evaluation mechanisms established by the Company. Throughout this period, there have been no formal findings indicating misconduct, noncompliance, or material governance failures. Naturally, every director is subject to criticism and evaluation. This is healthy. What I consider important is that such evaluations be based on verifiable facts and objective criteria. Accordingly, Previ’s argument that the replacement is intended to “strengthen governance” becomes contradictory if the process disregards the established performance evaluation procedures. If a director has received positive assessments through the Company’s governance structures, ignoring institutional information in order to carry out a politically motivated removal constitutes, by definition, a weakening—not a strengthening—of governance. 5. Strategic Assessment of the Situation It is not my role to speculate about motivations. My role is to analyze the grounds presented. In governance matters, the greater the impact of a decision, the greater the consistency required in its underlying rationale. My sole concern is that any decision of this nature be aligned with the Company’s best interests and supported by objective, transparent, and verifiable elements. 6. Executive Assessment The absence of a requirement for cause in a removal (ad nutum) is accompanied by a duty of truthfulness whenever reasons are expressly stated: shareholder discretion is subject to the overriding limits imposed by the doctrine of determining facts and the principle of objective good faith. The assessment is that this situation may have moved beyond the boundaries of ordinary corporate law and entered the realm of abuse of voting power and potential regulatory violations. If the stated justifications are false or materially weak, the removal ceases to be a legitimate exercise of shareholder rights and may become an act subject to annulment or compensation, as it violates the duties of loyalty owed to the Company and the transparency required by the capital markets.

Publicly Held Company CNPJ No. 33.592.510/0001-54 NIRE 33.300.019.766 VOTING STATEMENT Ref. Meeting of the Board of Directors of Vale S.A. Board member Marcio Antonio Chiumento (the “Board Member”), in his capacity as a member of the Board of Directors of Vale S.A. (“Vale” or the “Company”), hereby submits this voting statement to the table of the Meeting of the Board of Directors, held on 19 June 2026, at 3:00 p.m. (“BOD Meeting”), requesting that it be received by the Table and filed at the Company’s headquarters. The BOD Meeting was called to deliberate on the calling of an Extraordinary General Meeting of the Company’s shareholders (“EGM”), pursuant to the request to call an EGM submitted by Caixa de Previdência dos Funcionários do Banco do Brasil – Previ, a shareholder holding 6.92% of the Company’s share capital (“Previ”), on 11 June 2026, based on Article 123, sole paragraph, (c), of Law No. 6,404/76 (the “Brazilian Corporate Law”). The aforementioned provision of the Brazilian Corporate Law states that shareholders representing at least 5% (five percent) of the share capital may call the General Meeting when the managers fail, within 8 (eight) days, to comply with a duly substantiated request for calling it, indicating the matters to be addressed. CVM Resolution No. 70 reduces such percentage according to the issuer’s share capital, which in the case of the Company is 1% (one percent). In the specific case, Previ requested the calling of the EGM to deliberate on: (i) the removal of Mr. Daniel André Stieler from the position of member of the Board of Directors; (ii) the appointment of Mr. José Mauricio Pereira Coelho as a full member of the Board of Directors, to complete the current term of office; and, if the matter set forth in item (i) above is approved, (iii) the election of the Chair of the Board of Directors. Previ based the request on the need to improve the Company’s corporate governance, as well as to strategically align the actions of the Board of Directors with the creation of sustainable long-term value. In its request, Previ also declared support for the nomination of Mr. Manuel Lino Silva de Sousa Oliveira for the position of Chair of the Board of Directors, on the understanding Classification: Confidential that his possible conduct would contribute positively to strengthening governance practices, improving strategic management, and aligning with the interests of shareholders and stakeholders. There is no doubt that the request complies with the requirements set forth in the Brazilian Corporate Law and in CVM regulations for the calling of the EGM. After all, Previ holds an equity interest well above the minimum required shareholding, and the request was based on the improvement of the Company’s corporate governance practices, in addition to the fact that the matters fall within the competence of the General Meeting of shareholders. In cases such as this, the Board of Directors must carry out a formal and objective analysis of the request in order to verify whether it meets the legal requirements for calling the General Meeting, namely: the existence of (1) minimum shareholding and (2) substantiation, with the matter, or matters, to be deliberated upon being within the competence of the general meeting of shareholders. It is not for the Board to make any value judgment regarding the need, timeliness, motivation, or convenience of the grounds of the request or of the matters proposed therein1. As legal scholarship teaches: “9 (...) Lastly, the law creates supplementary authority for the benefit of shareholders representing at least 5% (five percent) of the voting capital, when the managers fail, within 8 (eight) days, to comply with a request for calling a meeting that such shareholders present, duly substantiated, with indication of the matters to be addressed. Also in this case the law makes no reference to the need for serious or urgent reasons, the legislator being satisfied with the due substantiation that must support the request for calling a meeting submitted by the shareholders entitled to do so, representing at least 5% (five percent) of the voting capital. (...) 1 As set out in CVM Proceeding No. 19957.005474/2020-29 and CVM Proceeding No. RJ2005/3945. As also pointed out by (i) José Luiz Bulhões Pedreira and Alfredo Lamy Filho (Coordinators), Direito das Companhias; (ii) José Alexandre Tavares Guerreiro, in “Convocação de Assembleia Geral por Acionista”, Revista de Direito Mercantil, Industrial, Econômico e Financeiro; and (iii) Nelson Eizirik, in A Lei das S.A. Comentada, Volume II. Classification: Confidential (...) 12. In our opinion, managers are not vested with the authority to judge whether the substantiation invoked by the requesting shareholder or shareholders is sufficient or not so that, upon granting the request presented, they proceed with the calling of the general meeting. The function of the managers, in this regard, is merely to verify the concurrence of the two formal requirements established by law: a) the percentage of standing of the shareholders submitting the request for calling the meeting and b) the existence of due substantiation. It should be reiterated that, also in the case of item c of the sole paragraph of Article 123, the managers’ authority is bound, and they are not permitted to assess the reasons of convenience and timeliness stated by the shareholders in the request submitted. For this reason, the doctrine of Modesto Carvalhosa is correct, according to whom “the grounds set out in the request for calling the meeting shall be examined by the shareholders at the general meeting. Only there, through discussion and deliberation, will its validity or otherwise be determined. And if, eventually, it concerns an abuse of right, it is only at the conclusion of the work of the general meeting that the requesting shareholder’s liability may be determined (Comentários à Lei de Sociedades Anônimas, vol. 4, p. 193)”2 (emphasis added) This conclusion becomes even clearer in the present case, since the proposals to be deliberated upon at the EGM concern the removal and election of managers, as well as the possible election of the Chair of the Board, matters reserved by the Brazilian Corporate Law and by the Company’s Bylaws to the shareholders and which must be decided at a General Meeting. Even if there were doubt as to the Company’s interest in the replacement – which is admitted solely for the sake of argument – the EGM is the most appropriate forum to resolve any doubt. The Board members should not replace the shareholders in their judgment regarding the grounds presented by Previ for the replacement, under penalty of being held liable3. The Brazilian Corporate Law (Article 1404) grants the General Meeting the power to elect and remove, at any time, the members of the Board of Directors, there being no guarantee or right of a manager to “complete” his or her term of office. The law likewise does not require that any decision of the General Meeting to remove a manager be substantiated, and the CVM has confirmed, on more than one occasion5, that no substantiation is required for removal except in the specific cases of separate election under Article 141, §4 of the Brazilian Corporate Law, or of an employees’ representative, which is not the case here. 2 José Alexandre Tavares Guerreiro. Convocação de Assembleia Geral por Acionista. Revista de Direito Mercantil, Industrial, Econômico e Financeiro. No. 41, pp. 155-156. 3 The Board of the Brazilian Securities and Exchange Commission has already ruled accordingly, as reflected in the vote of then-Chair Marcelo Trindade in Administrative Sanctioning Proceeding CVM No. RJ2005/7229, which discussed the conduct of the Chair of the Board of Directors in “canceling” a General Meeting that would deliberate on the removal and election of Board members. According to the vote: “preventing the holding of the meeting, in addition to preventing the application of all legal and bylaw provisions designed precisely to resolve the impasse that existed, would end not only by ensuring the continuity in the exercise of control power of those who had elected the Chair of the Board himself, but also by leaving without an institutional solution the issue that centralized the corporate interest at that moment”. 4 Article 140. The board of directors shall be composed of at least 3 (three) members, elected by the general meeting and removable by it at any time, and the bylaws shall establish: (...) 5 Such as, for example, Administrative Proceeding CVM No. 19957.004743/2016-53 and Administrative Proceeding CVM RJ 2007/266. Classification: Confidential For these reasons, I vote in favor of approving the calling of the EGM to deliberate on the matters set forth in the request for calling submitted by Previ, as well as in favor of the nomination of Mr. Manuel Lino Silva de Sousa Oliveira for the position of Chair of the Board of Directors, as I understand that he meets the legal requirements. Rio de Janeiro, 19 June 2026 Marcio Antonio Chiumento Board Member Statement and Vote of Director Marcelo Gasparino concerning the Calling of an EGM and the Proposal to Change the Composition of Vale’s Board of Directors Free translation of the original in Portuguese. In the event of any discrepancy, the Portuguese version shall prevail. 1. Context Vale’s Board of Directors was elected for the 2025–2027 term at the Annual General Meeting held on April 30, 2025, by means of majority slate voting. It is therefore a unified term, proceeding in its ordinary course, with only nine months remaining until its expiration and six months until the presentation of the first list (long list) of potential candidates to be nominated to serve in the 2027–2029 term. That election resulted from a robust and structured process, which included: • Board performance assessment; • application of a skills matrix; • 360-degree assessments of the Board of Directors and the Executive Committee; • advisory support from the international consulting firm Korn Ferry to identify candidates aligned with the Company’s needs. In 2025, with the “Conselheiros em Ação” program in progress, the new directors Anelise Lara, Franklin Feder and Wilfred Bruijn underwent a strong onboarding process. The recomposition of the advisory committees substantially strengthened their independence, notably: • Heloisa Bedicks as Coordinator of CARE; • Bill Bruijn as Coordinator of CACP. In addition, the technical strength of the committees was reinforced, notably through: • the admission of Franklin and Heloisa Bedicks to CIG; • the admission of Anelise and Reinaldo to the composition of CACP; • the recomposition of the other committees exclusively with independent members (CSUS, CPR and CARE). 2. Board Activities in 2025 The Board carried out strategic international agendas, including: • missions to the Middle East to visit operations and to Japan to celebrate the 70th anniversary of Vale’s presence in that country (August), with the participation of directors, the CEO and other members of the Executive Committee (“EC”); • the presence of the Chair of the Board in China (November) at IBLAC; • participation in Vale Day in London (December), with the presence of most of the Board and the Executive Committee. These initiatives culminated in the main milestone of the period: the successful CEO succession process conducted between January and October 2024, with the transition from Eduardo Bartolomeo to Gustavo Pimenta, confirmed in the shareholder roadshow held in London, Boston and New York in March 2026. 3. Considerations on the CEO Succession Process Although it would not be necessary to put this on record, it is worth noting that the CEO succession process generated internal divisions: • Group considered victorious: supported the opening of the succession process in January 2024, defended its legitimacy, demonstrated that the external interference planted in the press would not occur, and supported the choice of an internal candidate; • Group considered defeated: expressed concern regarding political interference, voted against opening the succession process, even though it was provided for in the Company’s Management Appointment Policy, including preliminary discussions involving external names who, at the time, led competitors. Despite these divergences, the process was successfully concluded, reinforcing the Company’s governance. 4. Evolution of Corporate Governance As set forth in the Board Performance Report prepared by the Governance Department and presented on this date, there has been consistent evolution in governance practices since 2020, as evidenced by the following Company documents: • Manuals and proposals for Annual General Meetings; • Reference Forms; • Governance Reports; • Annual and Management Reports; • Forms 20-F; • Financial Statements and IFRS reports; • Ethics and Compliance Reports; • LID reports; • candidate materials prepared by Korn Ferry (2025). These advances reflect the quality of the work carried out by the Board of Directors, notably CPR in 2024 and CIG in 2025. 5. Relevant Facts The shareholder Previ requested the calling of an Extraordinary General Meeting (“EGM”) to address: • the removal of director Daniel Stieler; • the election of José Maurício Pereira Coelho to the vacant seat on the Board; • the election of director Ollie Oliveira, current LID, as the new Chair of the Board of Directors. 6. Analysis of Complexity Practical cases analyzed indicate that proposals to remove directors without consistent grounds, especially in the absence of any serious facts, do not succeed. They do, however, cause enormous institutional instability, affecting not only the Board, but mainly the executive management of the companies. In comparable situations, such initiatives have not prospered. Thus, the feasibility of the proposal in the present case is questionable. It is important to record the perplexity caused by an independent member of the Board, chosen by his independent peers to be the point of communication with shareholders other than reference shareholders (LID), and to support the Chair in the relationship with those same shareholders, accepting, in the dead of night and without prior notice of his desire, to participate in a process aimed at removing a Chair of the Board and occupying his position. In any serious American company, or in a company of Vale’s size in Europe, no credibility would be given to a letter requesting the removal of a Chair of the Board without unequivocal and well-founded proof of a serious failure by the officer. The Company now runs the risk of losing market value if shareholders interpret this negatively. It is in the best interest of the Company, and for the preservation of the integrity of its governance structure, and above all for the shielding of the Executive Committee, which, according to information received, has also been subject to external pressure in relation to the regular conduct of its business. In May 2026, I participated in INSEAD’s Program for Board Chairs and Directors – LEADING FROM THE CHAIR, and I perceive adherence between the practices of our Chair of the Board and of the committee coordinators and the program’s teachings. I can state, without any doubt, that Vale’s Corporate Governance is the best among all the companies where I serve as a director – VALE, PETROBRAS and METALFRIO –, where I have served as Chair of the Board – ONCOCLÍNICAS, ETERNIT and USIMINAS –, and in other relevant or complex companies, such as ELETROTRAS (currently AXIA), BANCO DO BRASIL and CEMIG, among others. 7. Potential Effects of the EGM An EGM with an agenda involving the election of directors and of the Chair of the Board opens space for broad shareholder participation, allowing other shareholders to present alternative candidates, especially those who viewed Previ’s hostile movement as a risk of political interference in this process. Relevant background: • At the 2021 Annual General Meeting, four alternative candidates were nominated by shareholders dissenting from the twelve management nominees. Thus, there were 16 candidates running for 12 seats, and the result was considered surprising at the time, because the four alternative candidates were elected. Vale’s former CEO described the four elected directors as “mutinous directors,” referring to the four directors who allegedly participated, together with a group of shareholders, in a mutiny to take the seats. Nothing could have been more unfortunate. This precedent demonstrates the degree of unpredictability of such processes, and also that, at the 2025 Annual General Meeting, there was an alternative candidate to the Management Slate who, also due to the recognition of the work of this Board, was not successful. If this movement results in the removal of the current Chair of the Board, but in the election of an outsider who, to date, is not part of the process, the requesting party and the other director who was also elected by it should reflect on whether this corporate adventure, which some call a hostile takeover, was or was not beneficial to the Company. 8. Aggravating Factors and Risks of Developments I record my repudiation and indignation with respect to the information of which we became aware this week. I also consider abominable the possibility that Board meetings may have been clandestinely recorded, which deserves investigation and the appropriate reprimand. 9. Recommendation of the Nomination and Governance Committee – CIG I – Calling of the EGM Despite the disagreement regarding the absence of adequate grounds, CIG recommended the calling of the EGM on this date, with the statutory notice period counted from June 22, 2026. II – Removal of Director CIG recommended taking a position against the removal of director Daniel Stieler, based on the regular performance of the Board in recent years, especially since the 2025 Annual General Meeting. 9.1. Developments that, if the shareholders at the EGM resolve to remove Director Stieler, must be addressed by the Board in this call notice Considering Vale’s nature as a corporation, the Board shall deliberate on: III – Nomination of Candidate to the Board CIG recommended, in line with the process conducted by CIG (2024–2025) and the Management Appointment Policy, the nomination of a candidate who participated in the selection process conducted by Korn Ferry in 2024 and 2025, according to the “PROGRESS REPORT” issued in November 2024, namely: • Ieda Gomes Yell The importance of increasing gender diversity in future compositions is also highlighted, in accordance with the assessment of an international consulting firm that interacted with the Chair of the Board, the Coordinator of CSUS and the LID in the first quarter of 2026, and pointed out the weakness of the current 2025–2027 Board composition on this specific matter. Member Marcelo reminded everyone that candidate José Maurício served as Chair of Vale’s Board until 2021 and, in the 2020–2021 Nomination Committee, was the author of the proposal to amend the Bylaws included in the EGM called in March 2021 to include the illegal article creating the NEGATIVE VOTE, which would have granted a group of shareholders, at the time also the controlling group, the power to veto the election of any candidate, which was deemed illegal by SEP/CVM at the time. IV – Nomination of Candidate for Chair of the Board CIG discussed the matter, and Coordinator Daniel, considering the Bylaws, which provide: 1. that the Chair and Vice-Chair of the Board are elected directly by the General Meeting; 2. that, at the 2025 Annual General Meeting, Daniel was elected Chair and Marcelo was elected Vice-Chair. As a means of preserving internal cohesion, the Coordinator indicated the Vice-Chair as the natural candidate for succession, taking the following position: • against the nomination of Ollie Oliveira; • in favor of nominating the Vice-Chair of the Board to run for Chair of the Board. Member Marcelo followed the position against the nomination of candidate Ollie and recorded his abstention regarding his own nomination. 10. Vote A) IN FAVOR of calling the EGM on this date; B) AGAINST the removal of Director Daniel Stieler, as there are no adequate grounds, and because I understand that there is a risk of political interference in this movement, as demonstrated by the presentation on the Evolution of Vale’s Corporate Governance between 2023 and 2026, which I request be considered attached to this VOTE. Given that it is this Board’s duty to address all possible scenarios arising from the outcome of item 1 of the EGM, I vote as follows: C) IN FAVOR of the Board’s nomination of candidate IÊDA GOMES YELL, as she is a professional recognized nationally and internationally and meets the qualifications pursued by the Skills Matrix, thereby serving the best interest of the Company; D) IN FAVOR of Director Heloisa’s ALTERNATIVE PROPOSAL that the Board’s nomination comprise the two candidates, Marcelo and Ollie, for nomination by the Board, with the current Vice-Chair of the Board abstaining from his own nomination as a candidate for Chair of the Board, given that he is an independent director who joined this Board in 2020, at the time upon nomination by minority shareholders (institutional investors), served on four committees, was coordinator of CSUS and currently coordinates CPR. Rio de Janeiro, June 19, 2026. MARCELO GASPARINO DA SILVA For the purposes of recording in the minutes of the Extraordinary Meeting of the Board of Directors held on June 19, 2026, I hereby express a reservation regarding the regularity of the resolution adopted, due to the participation and exercise of the vote by a director in a clear situation of conflict of interest. The minutes report that there were no questions about a potential conflict of interest. However, I asked this question to the legal advisors present at the Board of Directors Meeting and, even though I had their report to the contrary, the then Chairman of the Board of Directors participated in a meeting that was deliberating on a matter directly related to his own dismissal, a circumstance that configures a typical situation of conflict of interest, as it involves direct and personal interest in the deliberation. Under the terms of the applicable corporate law, it should be noted that article 156 of Law No. 6,404/1976 establishes that the manager may not intervene in an operation or deliberation in which he has an interest conflicting with that of the company, and, in this case, must inform the other members and refrain from participating. In addition, article 155 of the same Law (duty of loyalty) imposes on the manager the duty to act in the interest of the company, prohibiting the use of his position to obtain personal advantage or act in a conflicting situation. Added to this is the provisions of article 153 (duty of diligence), which requires prudent, informed conduct in line with the social interest. Such rules are reiterated by POL-0048-G – Vale's Conflict of Interest Management Policy, which establishes, in item 4, that there is a conflict of interest when the agent's independence in decision-making is compromised. In this case, as required by item 6.2, the director, as key personnel of the management in a conflict situation, was obliged to: (i) immediately declare the conflict, (ii) withdraw from the discussions and deliberations and (iii) ensure the formal registration of the situation. Thus, the participation of the Chairman of the Board in the discussions – and effective exercise of the vote in the resolution – regarding a matter in which he has an evident individual interest, in violation of article 156 of the Brazilian Corporation Law and the Conflict of Interest Management Policy, not only compromises the integrity of the resolution recommending voting to shareholders on a matter of interest to them – subjecting the respective manager to the potential sanctions and liabilities arising therefrom –, how it can generate relevant impacts in relation to the General Meeting and the adequate formation of the will of the shareholders and the validity of the deliberative process. In view of the above, I request that this statement, as well as the express reference to the potential conflict of interest verified in the Board of Directors' Meeting, be fully recorded in the minutes, pursuant to article 130 of Law No. 6,404/1976, for the purposes of transparency, preservation of rights and eventual regulatory verification. In addition, I express my disagreement with the annexes. Marcio Antônio ChiumentoVALE S.A.
