Subject: Risk Management Cluster: Corporate. Identification: POL-0009-G / Version: 08. Use: Public. Resolution: DCA – 033/2025. Issued on: 11/27/2025. Responsible: Executive Vice-Presidency of Finance and Investor Relations. Review until: 11/27/2030. - 1 of 6 - Corporate Policy 1. General Guidelines Vale S.A. ("Vale" or "Company") is committed to managing Risks proactively and effectively, prioritizing the safety of its Employees and Third Parties, the communities where it operates, and caring for the environment, in accordance with its values, Code of Conduct, regulatory documents, and governance rules. "Life Comes First" is a core value that guides Vale's activities. Vale seeks to adopt the best market practices as a reference in its operations, aiming to prevent lives from being lost or negatively impacted. Vale's Risk Management consists of coordinated activities that support and guide the Company in its decision-making processes related to Risk. This process consists of four stages: (i) Risk Identification; (ii) Risk Analysis and Treatment; (iii) Risk Monitoring; and (iv) Risk Communication and Reporting. These activities should contribute to: • Promote a risk management culture to add value to the organization by optimizing the flow of information needed for decision-making in a transparent manner and aligned with Vale's institutional objectives, to avoid or mitigate negative impacts on people, communities, the environment, operational continuity, and reputation. • Support the strategic planning and sustainability of Vale's businesses. • Optimize capital allocation and strengthen Vale's asset management based on mapped risks. • Strengthen Vale's risk management governance practices, based on the Lines of Defense concept. • Adopt as references the concepts and guidelines of ISO 31000, ISO 55000 and COSO-ERM in Risk management, and RBPS (Risk Based Process Safety) for Process Safety. • Use the Risk Appetite methodology as a tool to guide the Company in the business decision-making process, in the allocation of capital and in the formulation of actions to respond to the mapped Risks. • Support the assessment of potential impacts related to new investments, acquisitions, and divestments, based on Vale's Risk Map and Appetite. • Map Emerging Risks in order to seek timely solutions that minimize possible negative impacts on the Company's business objectives. • Apply a Risk response strategy to define Risk treatment, according to the priority level classification of the Risk Matrix and weighted according to the Company's Risk Appetite, according to the following levels: • Very high: Implementation of appropriate measures to effectively reduce the level of Risk, which must be initiated quickly, except in cases where the Risk Appetite is high. • High: Implementation of recommended measures in accordance with best practices to effectively reduce the level of risk. These measures should be implemented promptly, except in cases where the risk appetite is high. If, after an assessment based on technical aspects, risk reduction is not reasonably possible, continuous monitoring must be carried out to ensure effective risk control. • Medium: Management to avoid the escalation of the risk level. • Low: Acceptable, without dispensing with risk level management. Vale's Risk Management system adopts a specific taxonomy, detailed in an internal regulatory document, which must be read and interpreted in conjunction with this Policy. - 2 of 6 - Corporate Policy DCA 033/2025 Rev.: 08 - 11/27/2025 POL-0009-G PUBLIC 2. Scope This Policy applies to Vale and its subsidiaries1, in Brazil and in other countries, to all Employees and members of Key Management Personnel, always in compliance with the Bylaws, constitutive documents and applicable legislation. 3. References • POL-0001-G – Code of Conduct. • POL-0005-G – Human Rights Policy. • POL-0012-G – Climate Change Policy. • POL-0016-G – Anti-Corruption Policy. • POL-0019-G – Sustainability Policy. • POL-0025-G – Sanctions and Export Controls Policy. • POL-0029-G – Internal Audit Charter. • POL-0035-G – Vale Management Model Policy - Vale Production System - "VPS". • POL-0037-G – Safety and Geotechnical Mining Structures Policy. • POL-0041-G – Misconduct Management Policy. 4. Definitions Risk Appetite: For the purposes of this Policy and in a concise manner, it refers to the Risk scale that guides the organization in pursuing its strategic objectives. It should be noted that Risk Appetite does not represent, in any circumstances, any acceptance or assumption of the probability of risks of any kind or nature materializing into concrete results or events by Vale. Risk Appetite Statement: Internal document that establishes the appetite scale for each Risk category present in the Company's Integrated Risk Map. Employee: Any permanent or temporary employee, interns, young apprentices and/or trainees at Vale. Lines of Defense: Risk management governance model in which areas, their respective responsibilities and processes that assist the Company in the effective Risk management process are identified. Integrated Risk Map (or "Map"): Instrument that contains the set of Risk themes that need to be assessed and monitored, organized by categories, according to the taxonomy established in an internal normative document. Risk Matrix: Graphical representation of risk classification based on the combination of frequency/probability and severity of events, establishing a risk priority scale, with each event classified as Very High, High, Medium, or Low. This analysis allows comparisons between potential risk events, enabling appropriate risk management. Key Management Personnel: For the purposes of this Policy, these are the members of the Board of Directors, the Advisory Committees to the Board of Directors, the Executive Committee, and the executives who report directly to the Company's Board of Directors, as well as the non-statutory Executive Vice Presidents who report to the President. Severity Ruler: Used to standardize the measurement, qualitative or quantitative, of the potential negative impact of Risks and assist in the classification of Risks. It does not reflect, under any circumstances, the degree of relevance attributed by the Company to potential impacts in their various dimensions, always requiring the recording of the assessment rationale. 1 To learn about the classification of subsidiaries, please refer to POL-0043-G. - 3 of 6 - Corporate Policy DCA 033/2025 Rev.: 08 - 11/27/2025 POL-0009-G PUBLIC Probability Ruler: Used to estimate, in qualitative or quantitative terms, the frequency/probability of occurrence of a potential Risk, always requiring the recording of the rationale for the assessment. Risk(s): The effect of uncertainty on organizational objectives, which manifests itself in many ways and has a potential impact on all dimensions of the business. Business Risks: Relevant potential risks that, if they occur, could impact people, communities, the environment, operational continuity, reputation, and the achievement of the company's overall business objectives and strategy. These are risks with very critical potential severity in Residual Risk, that is, the extent of present risk mitigated by the existing control environment. Emerging Risks: These are new potential risks or already known risks, but under new or different conditions and/or circumstances, which have a high degree of uncertainty regarding their trend, severity, and probability of occurrence. They are typically influenced by external factors and are therefore difficult to predict. They may become presentbut are not expected to materialize within the next five years, and therefore, clear monitoring indicators may not be available in the market. Priority Risk Themes: These are included in the Integrated Risk Map and are subject to detailed monitoring of classification, mitigation and consequences, based on the analysis of the Risk Matrix and considering the Risk Appetite. Third Parties: For the purposes of this Policy, this refers to any individual, company or entity with which Vale does business, including Suppliers, Customers and business partners. 5. Governance Vale has an integrated risk management governance system based on the Lines of Defense concept, designed to optimize the flow of communication for decision-making and reinforce alignment between strategy, performance, and risk management. The general risk management guidelines that guide Vale's business are established by the Board of Directors, which includes the Audit and Risk Committee. Among other responsibilities, the Committee is responsible for overseeing the adequacy and effectiveness of Vale's risk management processes. The Board of Directors and the Audit and Risks Committee exercise their responsibilities under the Bylaws, their Internal Regulations, and applicable legislation, and, for the purposes of this Policy, through periodic monitoring cycles.

It is determined that the Executive Committee maintain Executive Risk Committee(s) of an advisory nature with the purpose of advising it, in accordance with its scope of action, in the management and monitoring of Risks, as well as in pertinent deliberations. 6.
