In 2025, the Board was dedicated to the main strategic issues for Vale, with emphasis on approving relevant projects, strengthening integration and engagement with the Executive Committee and the main stakeholders, including investors, customers, strategic partners and local and global authorities. Another highlight was the intensification of its presence in communities and operations, developing levers that will support Vale's ambition: to lead mining in generating value in an ethical and sustainable way. The decisions taken have strengthened the Company's, prioritizing the safety of people and the integrity of our assets, ensuring solid and constant performance in different market scenarios. The Board's performance and activities With a highly disciplined agenda, adherence to the annual work plan and a focus on strategic topics, the Board's work in 2025 covered discussions on topics such as operational safety and stability, dam and risk management, succession and evaluation of the Executive Committee and the Board of Directors, evolution of the organizational culture and engagement with different stakeholders. All of this has reinforced the importance of the collegiate body in the face of Vale's challenges, maintaining a governance model with a solid structure, transparent communication, adequate risk management, discipline in capital management and the encouragement of a high-level institutional relationship. During the year, we conducted a robust onboarding program for the members elected during the year and strengthened the Board Members in Action program, with technical visits to operations in Brazil and abroad, including Oman, Japan, China and the United Kingdom, broadening the Board's knowledge of the Company's challenges and strengthening dialogue with relevant stakeholders. Attendance at global forums—such as COP30, NY Climate Week and international conferences in China, Japan and Oman—has enabled the Board to strengthen institutional dialogues, understand regional contexts and contribute to Vale's global positioning. Vale Strategy The Board, supported by the five advisory committees, maintained continuous oversight of the execution of the Vale 2030 strategy, aligned with superior portfolio positioning, disciplined operational performance and commitment to safety and sustainability. It has closely monitored the Company's performance in priority issues, including: • The progress of structuring projects, such as Vargem Grande and Capanema, as well as the Novo Carajás Program, in the Iron Ore Solutions business. Message from the Chairman of the Board of Directors Daniel André Stieler, Chairman of the Board of Directors VALE | 2026 Annual and Extraordinary Shareholders Meeting 3 • In Vale Base Metals, the expansion of copper in Carajás and the strategic redesign of the nickel business. • Progress in reparations, with 81% of commitments executed in the Brumadinho reparation, and significant progress on the compensation, environmental and resettlement fronts in the Mariana reparation. • Progress in tailings and dam safety management, including the implementation of GISTM in 100% of tailings dams and the achievement of the public commitment not to have any emergency level 3 structures. Cultural evolution In 2025, with a focus to guide the Company's cultural evolution and reinforce the clarity of the roles of our governance bodies, the Board continued the process of reviewing fundamental corporate policies—such as Anti-Corruption, Related Party Transactions, Conflict of Interest Management, Climate Change, Corporate Risk Management and Shareholder Remuneration— reinforcing the commitment to topics connected to the strategy and management of critical issues for the Company's businesses. Succession plan and executive compensation Regarding 2025, it is worth highlighting the Board's handling of the succession plan for the Company's leadership, carried out with technical rigor and transparency, with a view to an increasingly qualified and secure decision-making process, aligned with Vale's purpose. In addition, key appointments, organizational adjustments and the implementation of additional robust evaluation and development mechanisms were discussed. Executive remuneration remained linked to the generation of sustainable value, combining financial metrics and ESG indicators, especially focused on safety, decarbonization, reputation and people. Climate The Board actively oversaw the climate agenda, reinforcing the commitment to emission reduction targets, climate risk management, adherence to IFRS S1 and S2 international standards and the continuity of the decarbonization journey. Noteworthy is the progress made in tailings dam management, 100% compliance with GISTM and the elimination of the last emergency level 3 structure. The energy transition remained a strategic opportunity, with Mega Hubs, biofuels, green hydrogen and low-carbon steelmaking initiatives moving forward. Innovation In line with the vision of innovation as a vector of competitiveness, the Board followed the evolution of Smart Operations, with initiatives involving automation in mines and railroads, AI applied to predictive maintenance and safety, advanced processing, digitalization of chains and new industrial models (briquettes, Mega Hubs), which reinforce the Company's leading role in innovation. Final remarks We ended 2025 convinced that Vale is on a solid path of evolution and consolidation of global leadership in responsible, efficient, safe and innovative mining. The Board will remain vigilant, independent and committed to guiding the company in building the Vale of tomorrow: a corporation with high standards in corporate governance, recognized by society as a benchmark in safety, the most reliable operator in its category and people-oriented, thus leading the way in creating value in the mining industry through ethical and sustainable practices Daniel André Stieler, Chairman of the Board of Directors VALE | 2026 Annual and Extraordinary Shareholders Meeting 4 Message from Vale's CEO Gustavo Pimenta CEO of Vale Dear Vale shareholders, Last year was marked by consistent results and clear progress toward our ambition: to lead value creation in the mining industry through ethical and sustainable practices. Throughout the year, we advanced on several fronts, strengthening our safety and sustainability performance, improving operational excellence, and unlocking Vale’s growth potential. These achievements reflect the company’s cultural evolution and the discipline with which we are executing our strategy. I would like to highlight some of the key advancements achieved in 2025: Safety Safety is our core value, and we remain firmly committed to continue to work toward an accident-free workplace. In 2025, we reduced high-potential recordable injuries (N2) by 21% year-on-year, while process events (P1 and P2) reduced by 28%. We are building a more reliable and transparent organization, continuously enhancing monitoring, prevention, and emergency response capabilities to protect our people, our operations, and the communities around us. Dam management In August 2025, Brazilian authorities reclassified the Forquilha III dam from Emergency Level 3 to 2 - a major milestone that ensures none of Vale’s structures remain at the highest emergency level, fulfilling the commitment we made to society in 2020. Over the course of 2025, we reduced the number of structures under any emergency level from 14 to 9, and in 2026 we have already removed two additional structures, representing an overall reduction of 80% since 2020. We also continued to advance in the upstream dam decharacterization program, achieving 63% completion. In parallel, we successfully implemented the Global Industry Standard on Tailings Management (GISTM) across all our tailings dams. Integral reparation Our commitment to reparation has advanced with rigor and respect, and it remains central to building trust and restoring dignity in affected communities. In Brumadinho, we reached 81% completion of the commitments under the Integral Reparation agreement. We remain on schedule for the program’s conclusion in 2031, with all payment obligations to be fully settled in 2026. In Mariana, the Definitive Reparation Agreement, signed in 2024, accelerated reparation efforts, with BRL 73 billion disbursed to date. Of the obligations to perform under the agreement - including individual indemnification, resettlement, and environmental recovery - approximately 61% of the total financial value had been completed by the end of 2025. Future of mining Meeting the world’s growing demand for critical minerals requires a mining industry that is more efficient, innovative, responsible, and trusted by society. In 2025, we accelerated the adoption of safer, low impact, and transformative VALE | 2026 Annual and Extraordinary Shareholders Meeting 5 technologies, including autonomous solutions, artificial intelligence, and iron ore briquettes. Our iron ore production from circularity doubled, reducing the footprint of our operations. At the same time, our work in biodiversity, forest conservation, and decarbonization reinforces our long-term commitment to protecting natural systems and contributing to global climate goals. We are also deepening our social ambition, promoting inclusive development and ensuring a transition that benefits the communities where we operate. Operational excellence We delivered strong operational results, surpassing all production guidances while maintaining strict cost discipline across both Iron Ore and Vale Base Metals. Our operational excellence actions and efficiency programs are making Vale more resilient and better positioned to generate long term value. We are confident in our ability to continue delivering on our guidances, reinforcing Vale’s position as a reliable supplier at the low end of the industry cost curve. Customer-centric approach As we shape Vale’s next chapter, our strategy begins with a deep commitment to our customers. Their evolving needs guide how we design solutions, from high-quality iron ore to the metals essential for the global energy transition. Our flexible, high-quality product portfolio is built to maximize value creation across market cycles. By strengthening the link between our production systems and our clients -through initiatives such as Mega Hubs and advanced processing technologies- we are enabling more efficient and lower-carbon pathways for steelmaking and industrial development. Growth We advanced the acceleration of strategic projects such as Capanema, Vargem Grande, Voisey’s Bay, and Onça Puma, supporting our growth agenda. We also launched the New Carajás program, which aims to double Vale’s copper production and increase high-quality iron ore output. Carajás is one of the world's best regions for critical minerals, including copper and high-grade iron ore. Under this program, we are expanding investments to accelerate the development of this strategic mineral endowment. ESG risk perception With consistency and discipline, we continue to evolve our practices, deepening our engagement with stakeholders and enhancing transparency. As a result, we have seen sustained improvements in Vale’s risk perception among major ESG rating agencies and institutional investors. In 2026, we will continue to focus on positioning Vale to capture structural opportunities from a growing global demand for critical minerals. With our resilient operating model, a portfolio of world-class assets, and a strategic agenda centered on innovation, decarbonization, and tailor-made solutions for customers, we are well prepared to lead the mining of the future and generate sustained value for our shareholders and for society.

Our focus is on leveraging the iron ore, copper and nickel portfolios in which we already have significant competitive advantages, strengthening an efficient, resilient and customeroriented asset base. In iron ore, we seek global leadership with a flexible portfolio, competitive costs and a leading role in the decarbonization of the steel industry. In copper, we are accelerating growth with a view to doubling production over the next few years. In nickel, even in the face of a challenging scenario, we preserved our geographical advantage in strategic markets while advancing business efficiency. This strategy is supported by levers such as operational excellence, safety, innovation, discipline in costs and investments and the adoption of technologies that increase productivity and reduce environmental impacts, ensuring long-term sustainable growth. Superior portfolio We have built a resilient and competitive iron ore portfolio based on unique assets, quality, flexibility and a sophisticated global supply chain, ensuring rapid adaptation to market changes and tailor-made solutions for customers. In copper, we accelerated organic growth in Carajás, with the aim of reaching 700,000 tons per year by 2035, supported by differentiated mineral endowments, synergies and a robust pipeline. In nickel, we have prioritized operational efficiency and cost reduction to capture strategic opportunities. This position is supported by key levers that cut across all businesses: operational excellence, ensuring efficiency and stability; disciplined capital allocation, prioritizing projects with higher returns; agile and responsible licensing, increasing predictability; and rigorous project execution, reducing risks and accelerating ramp-ups.

VALE | 2026 Annual and Extraordinary Shareholders Meeting 15 Our culture The culture is what enables and drives the strategy. To achieve our ambition, we must foster a strong and consistent culture that places people at the center, guides our decision-making, and shapes our behaviors. It is within this context that the evolution of Our Culture emerged, a journey that began in 2019 and has continued to mature year after year. As the market evolves and our strategic drivers advance, we recognized the need to continue writing new chapters in this trajectory. Accordingly, throughout 2025, we worked across the organization to shape the evolution of our Cultural Narrative, an essential step toward the future we aspire to build. To support this journey, we launched an extensive process of collective construction, carried out through 53 listening sessions, in person and online, in Brazil and abroad. More than 1,200 people from all levels of the organization actively contributed, with 42% female participation, reinforcing diversity and representativeness. Ambition and Purpose remain central drivers, positioning Culture as a key enabler of the strategy and reinforcing “how” we intend to deliver it. The outcome is a clearer and simpler Cultural Narrative that reinforces the continuity of our journey and guides decisions and behaviors essential to leverage our strategy and achieve our ambition. Engagement Survey 2025 In 2025, we carried out a new cycle of the Engagement Survey with a simplified questionnaire, which resulted in record participation of 83% of employees and overall favorability of 77%.

This growth has been driven by investments in the Professional Training Program, with 700 trainees expected to be fully operational by 2025. Our workforce We believe the success of our business is only sustainable when everyone thrives. The promotion of a safe and healthy workplace, the expansion of diversity, equity and inclusion in our workforce, and a compensation strategy aligned with market practices, all reinforce our organizational culture among our 65,805 direct employees and 110,906 contractors. VALE | 2026 Annual and Extraordinary Shareholders Meeting 21 Diversity, equity, and inclusion are strategic levers for building a more sustainable, innovative, and safe Vale. We are committed to building a plural and inclusive Company for all, strengthening our reputation as an organization admired by society, sought after by top talent, and recognized as a benchmark in safety. We strive to ensure an environment of respect and psychological safety, promoting accessibility, removing barriers, and providing development opportunities for all. To this end, in 2025 we made progress with professional development programs, implementing bias-free recruitment practices, and strengthening initiatives to prevent and address harassment and discrimination. In 2024, we achieved 26.5% female representation in our workforce, one year ahead of schedule, and in 2025 we continued to advance, reaching 28.2%. In senior leadership, we achieved our target, reaching 25.3%, compared to 12.0% in 2019. 1 Does not consider Tecnored, which has its own DEI strategy management. As part of our commitment to being an anti-racist Company, we advanced toward our goal of having 40%¹ of leadership positions (coordinators and above) held by self-declared Black professionals by 2026, reaching 45%, a 7.4%. increase over the previous year. In 2022, we exceeded the legal quota of 5% for professionals with disabilities (PwDs), and in 2025 we reached 5.5% of active PwDs in the total of our direct employees at Vale in Brazil across a range of roles. We achieved our target, doubling the representation of women in senior leadership (executive manager positions and above), from 12% in 2019 to 28% in 2025. Diversity, equity and inclusion VALE | 2026 Annual and Extraordinary Shareholders Meeting 22 We will continue to strengthen our culture and processes to consolidate Vale as a benchmark in safety and operational excellence. At Vale, life comes first. Since 2019, we have completely overhauled our dam safety and management practices, transforming our organizational culture. This evolution is reflected in the way we operate, make decisions and manage risks, with the aim of ensuring an increasingly safer Vale for our employees, communities and society. Safety is also the foundation of our operational excellence, as there is a positive correlation between maintaining a safe workplace and achieving high levels of productivity and operational reliability. Occupational health and safety Life protection guides decisions, processes and behavior throughout the Company. In 2025, we made progress in consolidating this agenda, strengthening operational discipline, integrated risk management and the engagement of people in incident prevention, reinforcing individual and collective responsibility. The Safety and Operational Excellence Department is responsible for defining policies and technical guidelines for health, safety and operational risks within the Vale Production System (VPS), acting as the second line of defense in the Company's Risk Management. The strategy to consolidate Vale as a benchmark in this area is structured around three pillars of prevention: injuries and chronic diseases, fatalities and catastrophic accidents. Holistic Health Management Committed to the holistic health of its employees, Vale implements initiatives aimed at promoting the well-being of its direct employees and contractors, both within and beyond the Company, in compliance with local legal requirements and aligned with the World Health Organization’s agenda and the Sustainable Development Goals (SDGs). To mitigate the risks of occupational injuries and chronic illnesses, projects and control measures were implemented in 2025 to address deficiencies identified in activities classified as presenting High and Very High ergonomic risk, particularly in the Mining, Processing, Port, and Railway stages, where higher rates of medical absenteeism due to musculoskeletal disorders have been observed. Each Vale unit must have a formalized Ergonomics Program that defines the management process and includes the identification and management of ergonomic risks, with the objective of structuring, maintaining, and monitoring actions and initiatives aimed at eliminating or reducing such risks. This approach seeks to enhance the safety, occupational health, comfort and productivity of our employees. Taking care of mental health also remained a priority. Mental disorders are currently the second biggest reason for sick leave at Vale. To reduce Health processes Mental Health Ergonomics Basic working conditions Occupational hygiene Preventing fatigue Occupational health Dam safety and management VALE | 2026 Annual and Extraordinary Shareholders Meeting 23 these impacts, the Minas por Mentes (Mines for Minds) Emotional Health Program made progress in 2025, implementing intervention plans aimed at the areas identified as having the highest rate of absenteeism. The integration of the data enabled proactive intervention and the provision of additional psychosocial support to 4,464 employees. Obsession with Safety and Risk Management To advance our cultural evolution, we are committed to eliminating fatalities and fostering an increasingly safe environment. To this end, Vale has developed the Safe Behavior and Organizational Development strategy, which encompasses, among other initiatives, the Leading with Safety Program. One of the targets achieved was the training of 92% of the leadership at all hierarchical levels, representing more than 3,400 leaders. The initiative, launched in 2022, seeks to develop skills related to safe decision-making, conducting meaningful conversations about safety and understanding the impact of behavior on performance and promoting a culture of prevention, among other fundamentals. In 2025, the program was expanded to include leaders of contracted companies, strengthening shared standards of care across the value chain. The pillar of the program is aligned with the Vale Way of Leading. Controlling critical risks to save lives Critical Risk Management (CRM) is Vale's methodology for managing risks that pose a direct threat to life in operational activities. Its focus is to ensure that the critical controls are effectively implemented before work begins, by means of on-site checks at the location of the activity. The application of CRM makes it possible to identify, understand and control critical risks in a structured way, helping to preserve life and increase safety in operations. The methodology is supported by two integrated solutions: a mobile application, which gathers the checklists for critical controls, and the CRM Portal, which consolidates indicators, monitoring panels, nonconformities and action plans. In 2025, Vale made consistent progress in implementing CRM, supported by a structured change management strategy aimed at strengthening behaviors that prioritize life. The initiatives included the activation of the maintenance personnel of the Operations Vice‑Presidency in Brazil, as well as the training of leaders and occupational safety professionals in Brazil, Oman and Malaysia, as well as Capital Projects and Matrix Areas. Vale continues to implement initiatives to sustain the application of the methodology in the areas already covered and to prepare for its expansion throughout 2026. Scope 40,000+ Direct employees and contractors affected 14,000+ maintenance workers have conducted verifications 330,000+ verifications conducted 3.5 million+ controls verified 2,000+ leaders 1,000+ security professionals trained VALE | 2026 Annual and Extraordinary Shareholders Meeting 24 Target Performance in 2025 Comparison with 2024 I. To eliminate the number of fatalities 3 25% reduction II. To reduce N1+N2 compared to the result at the end of the previous year 14 22% reduction III. To reduce the number of exposures to the main health risk agents by 50% compared to 2019 levels by 2025 8,512 7.8% reduction IV. To eliminate all risk scenarios classified as “Very High” in the areas of Health, Safety, Environment, and Communities. During the year, we saw a 37.5% reduction in process security risk scenarios classified as “Very High”.* * It should be noted that risk management is dynamic and influenced not only by risk mitigation efforts, but also by the ongoing monitoring of protective barriers and the identification of risks associated with new operations and processes implemented in operational areas. In this regard, it is noteworthy that significant maturity has been achieved in the management and treatment of Very High risks, with rigorous oversight in the establishment and monitoring of strategies for their mitigation and contingency. Response readiness Vale is continuously preparing to respond quickly and effectively to unwanted events, through emergency response plans, crisis management and business continuity, structured based on the risks of operations and aimed at mitigating impacts on people, the environment, society and the business. In 2025, in addition to the tests and drills of the Emergency Action Plan for Mining Dams (PAEBM), we carried out more than 400 simulations in the business areas, covering scenarios of industrial emergencies, operational discontinuity and corporate crises. The initiatives resulted in improvement plans monitored by the leadership, continuously strengthening the Company's response capacity. We have also advanced in technology and response protocols, for example by approving a biodegradable fire extinguishing agent, which is more efficient and has less environmental impact, and by unifying the emergency number in operations in Brazil, eliminating telecommunication barriers. Advances like these reinforce our commitment to the continuous evolution of prevention and response processes. Health and Safety targets VALE | 2026 Annual and Extraordinary Shareholders Meeting 25 Dam management Since 2019, we have been continuously improving our tailings and dam management practices. Upstream Dam Decharacterization Program One of our key initiatives in dam safety and management is the decharacterization of all upstream structures in Brazil, including dams, dikes and drained stacks. Vale’s Upstream Dam Decharacterization Program initially covered 30 geotechnical structures, of which 19 were eliminated between 2019 and 2025, representing around 63% of conclusion. In 2025, we completed the decharacterization of the Grupo dam - the third upstream structure eliminated at the Fábrica Complex in Ouro Preto (Minas Gerais State) - and the Campo Grande dam, the first upstream dam at the Mariana Complex in Mariana (Minas Gerais State) to conclude its decharacterization works. The 11 structures that are still undergoing decharacterization have publicly disclosed schedules and project stages. Vale plans to eliminate 87% of the upstream structures by 2029, and eliminate the four most complex structures by 2035. Between 2019 and 2025, the program had a total expenditure of BRL 13 billion, with remaining provisions totaling BRL 11.5 billion in 2024. The decharacterization process is important for eliminating the long-term risks associated with upstream dams. However, the works required for the decharacterization process may affect the geotechnical stability of certain upstream tailings dams, potentially increasing the risk of structural failure, particularly in the early stages of the process. To mitigate risks: 1. we evacuated the areas downstream of the most critical dams, which are now uninhabited; 2. we have constructed physical barriers— Downstream Containment Structures (DCSs)— designed to contain tailings in the event of a breach; and 3. The dam designs incorporate appropriate levels of redundancy and we carry out critical works 2025 closed with no structures at emergency level 3 and around 63% of upstream dams eliminated.

With the completion of the decharacterization of the B3/B4 dam, the DCS that had been built as a safety measure during the decharacterization works was removed to allow the area to be restored, with full reuse of the material and mitigation of impacts on communities and the environment. Over the past two years, we have removed two dams from the most critical safety classification (Emergency Level 3), reflecting progress in assessing the actual condition and stability of the structures, as well as advances in the decharacterization works. We remain dedicated to the Upstream Dam Decharacterization Program. Commitment fulfilled in 2025: no dams at emergency level 3 In 2025, we achieved our goal of removing all dams classified at emergency level 3. This result was obtained after reducing the emergency level of the Forquilha III dam to level 2, enabled by new field and laboratory data, further studies and advances in instrumentation, providing greater knowledge about the structure. As a result, the safety factors met the criteria required for the reduction of the emergency level. This reduction is yet another example of the consistent and dedicated work carried out in dam safety over the last few years. Since 2020, the number of Vale structures at any level of emergency in Brazil has fallen from a peak of 35 to 9 in December 2025 (five fewer than in 2024) and then to 7 in February 2026. We remain committed to improving the safety conditions of these 7 structures that are still classified at some level of emergency. Among the measures adopted, we highlight the deepening of geotechnical knowledge of the structures and their foundations, the implementation of projects to reinforce safety, and the ongoing decharacterization of dams. We remain firmly committed to ensuring the integrity of these structures and promoting safety at all stages. Level 3 Dams by emergency level Rating under Brazilian legislation Level 1 Level 2 -74% -86% 20 35 4 7 24 2020 (Peak) 9 4 5 Dec -25 5 2026 (Estimate) 4 1 VALE | 2026 Annual and Extraordinary Shareholders Meeting 27 Global Industry Standard on Tailings Management (GISTM) Published in August 2020, the GISTM establishes a global benchmark for achieving the highest socio-environmental and technical standards in the management of Tailings Storage Facilities (TSFs), prioritizing the safety of structures throughout their entire life cycle, including planning, design, operation, and post-closure. The initiative requires mining companies to strengthen their technical, operational and governance commitments to ensure zero harm to people and the environment. The GISTM is the result of a joint initiative by the International Council on Mining and Metals (ICMM), the United Nations Environment Program (UNEP) and the Principles for Responsible Investment (PRI). In 2025, we completed the implementation of the GISTM across all our tailings dams, fulfilling our public commitment to apply the standard to all TSFs classified with “extreme” and “very high” consequence ratings, and we continue to maintain an ongoing monitoring process to ensure sustained compliance. For more information on Vale's compliance with the GISTM, click here. Alternatives to tailings dams A fundamental preventive measure underway is to reduce the dependence on tailings dams in our production processes. Vale already operates filtration and dry stacking systems for approximately 80% of the tailings generated at four major operational units (Brucutu, Conceição, Cauê, and Vargem Grande). In addition, new dry processing technologies remain a key component of the Company’s strategic research and development initiatives. Tailings governance Our tailings governance approach adopts several layers of protection, with the aim of improving our ability to prevent accidents: 1st line of defense 2nd line of defense 3rd line of defense Operational Geotechnical Area Geotechnical Department Audit and Compliance Department (Internal Audit and Whistleblower Channel) External agents Engineer of Record: dam safety inspections and performance assessments Independent Tailings Review Board (ITRB): a committee composed of external experts Periodic Dam Safety Reviews (RPSB): periodic technical reviews by external engineering companies PAEBM: Vale and communities together for safety The safety of the communities living near Vale's dams remains a priority. The Emergency Action Plan for Mining Dams (PAEBM) is in effect for all Vale dams in Brazil for which legal requirements apply, in compliance with the National and State Dam Safety Policies. In 2025, all dams classified as High Hazard Potential (HHP) received positive Declarations of Conformity and Operability (DCO), demonstrating Vale’s adherence to the highest safety standards. Engagement with communities is an essential component of the PAEBM. Vale conducts awareness campaigns, training sessions and periodic drills to ensure that residents know what to do in an emergency. In 2025, the company continued the “Civil Defense in Schools” project, launched in 2024, which became the foundation for the Minas Gerais State Education Plan for Civil Protection and Defense (PEE PDEC). Vale also supported the establishment of new Civil Protection and Defense Centers (NUPDECs) in municipalities affected by dams, including Itabirito, Sabará, and Santa Luzia (in Minas Gerais), among others. VALE | 2026 Annual and Extraordinary Shareholders Meeting 28 Our journey towards ESG leadership is focused on finding the best initiatives and technologies to minimize negative impacts and leverage positive results for nature and people. After all, our operations depend on nature and have a significant impact on it. To this end, we have established long-term commitments aligned with the UN's 2030 Agenda for Sustainable Development fostering the dialogue with stakeholders that is fundamental to the development and continuity of our business. In 2025, we released the Sustainability-Related Financial Information Report, available here, a significant step in alignment with the IFRS Sustainability Disclosure Standards, standards issued by the International Sustainability Standards Board (ISSB), and the CBPS Sustainability Disclosure pronouncements, issued by the Brazilian Sustainability Committee Statements (CBPS). The voluntary disclosure anticipates the requirements of CVM Resolution 193/23 by two years, reinforcing Vale’s commitment to transparency and the continuous advancement of its climate and sustainability reporting practices. Below we highlight some of our initiatives on ESG topics. Environmental Through a collaborative process involving internal and external stakeholders, we have established a set of six goals, with biodiversity as a crosscutting theme: 1. Make nature an essential aspect of our governance, management and decision-making. 2. Strengthen biodiversity management in our processes and value chain, assessing impacts, dependencies, risks and opportunities. 3. Leave a positive legacy through restoration and conservation, strengthening partnerships with society organizations, traditional communities and indigenous peoples. 4. Invest in innovation, co-production and sharing of technical and scientific knowledge, incorporating and valuing traditional knowledge. 5. Disseminate of knowledge, initiatives and results as a source of dialogue and engagement with the different stakeholders. 6. Influence transformative external agendas that contribute to positive results for nature (advocacy). We recognize that our operations primarily impact land use, vegetation cover, and watercourses. Accordingly, we have established voluntary targets and commitments through 2030 related to water and forests. We have advanced in implementing the Forest Target, a voluntary commitment to protect 400,000 hectares and restore 100,000 hectares beyond our operational boundaries by 2030. By the end of 2025, 45% of the target had been reached, with 25,364 hectares recovered and 200,093 protected. It is important to highlight the continued implementation of the 2030 Water Target, which foresees a 27% reduction in the specific use of fresh water by 2030, based on guidelines such as water efficiency, circularity and conservation of water bodies. By 2025, we had reached a cumulative position of 225 thousand hectares of recovered or protected forests, equivalent to around 45% of the voluntary target of 500 thousand hectares by 2030. Sustainability VALE | 2026 Annual and Extraordinary Shareholders Meeting 29 In 2025, Vale made significant progress in maturing its biodiversity management, strengthening the assessment of environmental impacts, risk management and the evolution of mitigation strategies, tools and practices. We started from the principle that knowing, restoring and conserving biodiversity is essential to operating responsibly and ensuring the long-term resilience of the business. Throughout the year, we prioritized the adoption of frameworks and tools that connect strategy to operations and projects, accompanied by the development of indicators and metrics to monitor performance. In this context, we have become early adopters of the Taskforce on Nature-related Financial Disclosures (TNFD), increasing transparency by disclosing information about our direct operations in Brazil. In 2025, Vale Base Metals (VBM) also released its TNFD report, presenting the results during COP30. For 2026, the TNFD is expected to be published for the international sites in Oman and Malaysia, making it possible to end the year with 100% of direct operations assessed under the framework approach. Within the supply chain, the Conexão ESG program marked the beginning of structured initiatives to engage and teach nature literacy to suppliers with high biodiversity and water criticality, through workshops held in 2025. Vale also plans to expand this work in 2026, applying the Localize stage of the TNFD-LEAP methodology, with the aim of deepening the understanding of the distribution of suppliers and their interfaces with ecologically sensitive areas. External recognition has reinforced this trajectory. Vale was featured in the GRI & TNFD Global Case Studies Report, in recognition of its nature management practices, and has consolidated relevant strategic partnerships, including the formalization, in 2025, of a partnership with the International Union for Conservation of Nature (IUCN), aimed at incorporating positive approaches to nature into operations and strengthening conservation and restoration agendas. Since 2024, the Company has also been a member of the Life Business and Biodiversity Coalition, using its methodology to measure impacts and evaluate biodiversity performance. Social We are part of the territories where we operate and actively contribute to their development. In this context, we seek to act as partners with communities, guided by our model of social action, whose non-negotiable principle is respect for human rights. This model is achieved by managing the risks and impacts of our activities on neighboring communities, combined with structured support for territorial development. In this context, we have made three commitments that guide our social action: 1. To support 500 thousand people out of extreme poverty. 2. To support all Indigenous communities in the vicinity of our operations in developing and implementing their plans to advance the rights set out in the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP). 3. To be among the TOP 3 of the main ESG assessments. Commitment to reducing poverty: As part of its commitment to help 500,000 people out of extreme poverty, Vale is organizing the Together Against Poverty program, which brings together companies, social organizations, academia, representatives of civil society and public authorities, with the aim of strengthening public policies and generating a lasting legacy for the territories. We are early adopters of the TNFD, increasing transparency on risks and opportunities related to nature, with reporting on direct operations in Brazil and presentation of Vale Base Metals' results at COP30 in 2025. VALE | 2026 Annual and Extraordinary Shareholders Meeting 30 The initiative is aligned with UN Sustainable Development Goal (SDG) 1 — No Poverty and adopts a Multidimensional Poverty Index (MPI), developed specifically for the program based on the MPI from the University of Oxford as an instrument for measuring and monitoring results. Vale recognizes poverty as a multidimensional phenomenon and therefore adopts the Multidimensional Family Monitoring (AFM) approach, which considers five fundamental dimensions: income, education, health, nutrition and infrastructure. This methodology is applied through the construction of personalized action plans, drawn up together with each family, with a focus on overcoming the deprivations identified. Over a period of up to 24 months, the families receive support to implement these actions, in conjunction with public authorities and local organizations. Periodic monitoring guides the efforts of families and the network of partners, strengthening the effectiveness and sustainability of the results achieved. Currently, around 60 thousand people take part in the 20 initiatives that have been implemented, mainly in the states of Pará and Maranhão. Approximately 14 companies have contributed to financing initiatives in the territories, totaling more than BRL 30 million since the program began. Supporters include BNDES, EGTC, Enesa, Fundação Banco do Brasil, Grupo Ápia, Instituto Equatorial, Logicalis, Michelin, Hatch, MIP, Plamont, Sotreq, U&M and Wheaton. Indigenous rights: 2025 marked concrete progress in engaging with communities and implementing the UNDRIP principles. Partnerships with the private sector are essential to increase the mobilization of resources. To this end, and to ensure transparency for donors, Vale set up the Philanthropic Fund in 2024, managed by the Institute for the Development of Social Investment (IDIS). In 2025, the fund was also presented to the international audience at an event held on the New York Stock Exchange (NYSE), further expanding its fundraising capacity and reach. Commitment to indigenous rights: Vale continues to make consistent progress in implementing its commitment to support, by 2030, all indigenous communities neighboring its operations in Brazil in the development and implementation of their own instruments to guarantee the rights set out in the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP). This commitment is materialized through technical support for the construction of Consultation Protocols, Territorial and Environmental Management Plans (PGTA) and Life Plans, strengthening the autonomy, protagonism and self-determination of indigenous communities. In 2025, concrete progress was made on this agenda. The Ka'apor People, from the Alto Turiaçu Indigenous Land (MA), have concluded their Life Plan, while the Tupiniquim People, from the Comboios Indigenous Land (ES), have drawn up their Consultation Protocol. This same period also marked the launch of a training program in Environmental Management, Climate Change, and Political Action for the Guajajara Indigenous peoples in Maranhão, who serve as Guardians and Warriors in the Forest in the Rio Pindaré and Caru Indigenous Lands. Engagement also began with the recently contacted Awá people in the Awá, Caru and Alto Turiaçu Indigenous Lands (MA). The Together Against Poverty program has already reached around 60 thousand people, with a focus on Pará and Maranhão, making consistent progress towards the goal of lifting 500 thousand people out of extreme poverty. VALE | 2026 Annual and Extraordinary Shareholders Meeting 31 With these advances, five of the eleven indigenous communities with which Vale maintains a relationship are already engaged in defining their instruments for guaranteeing rights, extending a trajectory that began in 2024 with the Kayapó People (PA), the first to conclude their PGTA and Consultation Protocol. The improvement in Sustainalytics' rating reflects the Company's ongoing evolution in sustainable practices and its alignment with the ambition to rank among the TOP 3 in the main ESG assessments. Improvements in ESG risk ratings: Reflecting the continuous improvement of our ESG practices and convergence with the expectations of the market and society, our ESG risk ratings have shown significant evolution. Agency 2019 2025 MSCI (AAA maximum / CCC minimum) CCC BB Sustainalytics (the lower, the better) 54.5 27 ISS Corporate (A+ maxium/ D- minimum) - C+ ISS Governance (the lower, the better) 10 1 DJSI (the higher, the better) 45 39 1 Dow Jones Sustainability World Index. Also known as CSA (S&P Global's Corporate Sustainability Assessment). Relationship with communities: Vale brought forward by one year the target of full coverage of priority communities in Brazil with Community Relationship Plans. Today, the 147 priority communities have active plans, strengthening long-lasting and structured relationships of trust. Community safety: We remain committed to reducing accidents involving community members by 40% by 2027. In 2025, 107 accidents were recorded, of which, regrettably, 12 resulted in fatalities. Nevertheless, there was a 33% reduction in the fatality rate compared to the previous year, reflecting the implementation of structural measures grounded in in-depth root-cause analyses. Vale continues to work collaboratively with communities, public authorities, suppliers, and other local stakeholders to strengthen a culture of prevention and reduce the recurrence of accidents. Promotion of culture: In 2025, the Vale Cultural Institute consolidated its role as one of the country's main private cultural promotion agents, allocating BRL 196.9 million to 165 cultural projects in 22 states and the Federal District, through the Rouanet Law. The investments generated a significant social impact by expanding access to culture, strengthening the creative economy in the territories and supporting vulnerable populations, contributing to the appreciation of Brazilian cultural diversity. Human rights agenda: Vale has made consistent progress in implementing independent human rights due diligence (IHDD) in critical operations and projects. In 2025, the second cycle was completed on the Northern Corridor, covering Serra Sul (PA) and the Ponta da Madeira Maritime Terminal (MA), and the second cycle began on the Southeastern Corridor, in the Itabira and Mariana (MG) complexes. At the end of the period, 80% of suppliers classified as high risk in Brazil had implemented mitigation measures, including assessments, training, inspections, action plans and continuous monitoring, reinforcing preventive risk management and alignment with international best practices. VALE | 2026 Annual and Extraordinary Shareholders Meeting 32 Climate change remains at the heart of Vale's strategy. By 2025, we have reinforced our commitment to climate resilience, intensifying actions to reduce greenhouse gas (GHG) emissions in our operations, value chain and products, in line with global best practices and the Sustainable Development Goals. Throughout the year, we consolidated audited data, strengthened internal monitoring controls and made consistent progress on the decarbonization roadmap, with a special focus on Scopes 1 and 2. In Scope 3, we advanced key initiatives, including the continued development of the briquettes and Mega Hubs projects, as well as strategic partnerships in the shipping sector focused, on the use of biofuels and the development of technologies to enhance energy efficiency. Climate targets Our climate targets are aligned with the Paris Agreement, including a 33% reduction in absolute Scope 1 and 2 GHG emissions by 2030, compared to a 2017 baseline, through operational improvements, fuel switching, and increased use of renewable energy, while seeking to reduce net Scope 3 emissions by 15% by 2035, supported by the development of less carbon-intensive products, strategic partnerships, and greater logistical efficiency. In the long term, we maintain our ambition to achieve net zero emissions in Scopes 1 and 2 by 2050, combining absolute reduction, technological advances and operational improvements, as well as incorporating Nature- Based Solutions as relevant instruments to generate socio-environmental benefits and enable the use of high integrity carbon credits. Learn more about our decarbonization strategy here. Climate governance The Global Climate Change Policy, revised and approved by the Board of Directors in 2025, reinforces Vale's commitment to climate resilience by integrating climate risks and opportunities into the Integrated Corporate Risk Map. The policy incorporates international standards, such as internal carbon pricing and analyses of trade-offs between economic viability and environmental impacts, and reaffirms the targets for Scopes 1, 2 and 3, as well as the ambition of net zero emissions by 2050. Climate governance is structured at multiple levels, with oversight of the Board, support from specialized committees and coordination by the Low Carbon Forum to ensure the execution of the decarbonization roadmap. This structure is reinforced by the linking of climate targets to performance mechanisms, with decarbonization indicators integrating variable remuneration, including short-term targets from the office of the Vice President for Sustainability (weight of 7.5%) and long-term ESG metrics in Vale's Actions Program (weight of 25%). Reduce absolute Scope 1 and 2 emissions by 33% by 2030 (compared to 2017). Eliminate net Scope 1 and 2 emissions (net zero) by 2050. Reduce net Scope 3 emissions by 15% by 2035 (compared to 2018). Climate change and decarbonization VALE | 2026 Annual and Extraordinary Shareholders Meeting 33 Climate risks and opportunities In 2025, we made significant progress in the robustness and transparency of our data, consolidating our leadership position by being the first global mining company to set emissions targets in 2020 and, subsequently, the first in the sector and in Brazil to voluntarily disclose the Sustainability-Related Financial Information Report, prepared in accordance with the CBPS standards, aligned with the IFRS and the TCFD recommendations developed by the ISSB. In line with this commitment, we will publish the report again based on 2025 data, broadening the scope beyond climate and contributing to the maturing of internal processes and the preparation of the market for mandatory disclosure from 2026. Our climate risk portfolio covers both transition risks—such as regulatory changes, carbon pricing and market volatility—and physical risks, including extreme weather events. We also consider operational challenges related to technological feasibility, the maturing of solutions for energyintensive assets, the acceptance of products with a lower carbon footprint and the development of economic instruments that internalize the cost of carbon, all of which are monitored continuously and reported transparently. In 2025, we made important progress in our decarbonization journey with our partners, of which we highlight the following: • We signed a Strategic Alliance Agreement with Petrobras for the supply of biobunker (fuel used in ships) and co-processed diesel with renewable content. Diesel R5, which has 60% lower carbon intensity, is currently being tested on the Vitória-Minas Railroad and at the Fábrica Nova mine in the Mariana Complex (MG). We are also advancing collaborations to develop more competitive natural gas supply models—an essential input for the production of pellets and iron ore briquettes. • We have signed a Strategic Alliance Agreement with Green Energy Park (GEP), an integrated European hydrogen Company, to offer decarbonization solutions to the global steel industry. Through this partnership, we will develop feasibility studies for the installation of a green hydrogen production unit in Brazil, which will supply a future Mega Hub—an industrial complex designed to manufacture low-carbon steel products. • We initiated testing of rotor sails on the Sohar Max, a 362-meter-long Valemax-type vessel with a cargo capacity of 400,000 tons. Developed by Anemoi Marine Technologies, the sails harness wind power to reduce fuel consumption and lower emissions. The trial on the Sohar Max marks the fifth wind propulsion project installed on vessels of varying sizes that provide services to Vale, either supported or financed by the company. Two more projects were planned until late 2025. • We have signed a Memorandum of Understanding (MoU) with Hydnum Steel to develop low carbon solutions for steel production. The agreement includes the joint assessment of the possibility of building an iron ore briquette plant at Hydnum Steel's main green steel project in Puertollano, Spain. The plant will start producing 1.5 million tons of rolled steel in 2026 and is designed to have an annual capacity of 2.6 million tons from 2030. • We have concluded a multi-year pellet supply agreement with Roheisengesellschaft Saar mbH (ROGESA), a joint subsidiary of AG der Dillinger Hüttenwerke (Dillinger) and Saarstahl AG. The agreement represents an important milestone in advancing the decarbonization of the steel industry. The agreement provides for the supply of blast furnace pellets from 2025 to 2027 and a flexible transition to direct reduction pellets from 2028, after the commissioning of ROGESA's direct reduction plant at the Dillingen site. • We signed a five-year contract with Wilson Sons to dock seven vessels at the company's shipyard in Guarujá, in the Port of Santos. Over the course of the contract, scheduled maintenance will be performed on five of the company’s tugboats and two ferryboats operating in Rio de Janeiro, resulting in an estimated 67% reduction in fuel consumption for the company. VALE | 2026 Annual and Extraordinary Shareholders Meeting 34 • We have signed a Collaboration Agreement with Caterpillar to test large battery-electric trucks and develop joint studies for ethanol-powered trucks. • We have signed a Collaboration Agreement with Komatsu and Cummins to develop dualfuel off-road trucks powered by a blend of ethanol and diesel. This pioneering project aims to reduce direct CO₂ emissions by up to 70% compared to diesel engines. These will be the first trucks of this size in the world—featuring a capacity of between 230 and 290 tons—to operate with ethanol as part of their fuel mix. COP 30 The mining sector plays a pivotal role in both the decarbonization agenda and the broader global climate agenda. COP30 represented an important opportunity for Brazil to highlight the interconnections between energy, climate, natural resources, and business, with strong engagement from the private sector. Vale, a longstanding participant in the United Nations Climate Change Conference, reaffirmed its commitments to global decarbonization and contributed to discussions on sustainable development models in the region. Its engagement centered on three pillars: (i) decarbonization across the value chain, emphasizing the role of critical minerals, innovative mining approaches—such as circularity—and Brazil’s potential in renewable energy and efficiency; (ii) naturebased solutions and the role of forests, linking biodiversity and the bioeconomy to scalable climate solutions; and (iii) a just transition and adaptation, contributing to discussions on climate resilience, respect for human rights, and differentiated responsibilities. Main initiatives on Vale's agenda during COP30: • The Essential Minerals Coalition, in collaboration with the Brazilian Business Council for Sustainable Development (CEBDS), the Brazilian Mining Institute (IBRAM), and 15 other companies, has positioned Brazil as a leading player in the supply of essential minerals for the energy transition, with studies indicating the potential to reduce emissions from the minerals sector by up to 90% by 2050, underpinning IBRAM's sectoral target. • The Carbon Measures coalition has advanced efforts to address one of the most significant gaps in the transition— reliable and comparable product-level carbon accounting—thereby enhancing transparency and enabling more informed and effective decarbonization decisions across the value chain. • The C.A.S.E. (Climate Action Solutions & Engagement) initiative, formed by Bradesco, Itaúsa, Itaú Unibanco, Marcopolo, Natura, Nestlé and Vale, highlighted Brazilian solutions capable of tackling the climate crisis at scale, expanding its presence during the COP with a space dedicated to debates and the presentation of private sector proposals to the conference presidency. • In addition, Vale contributed to the launch of the Global Circularity Protocol for Business of the World Business Council for Sustainable Development (WBCSD), reinforcing circularity in mining as a key lever for emissions reduction and greater resource efficiency.

VALE | 2026 Annual and Extraordinary Shareholders Meeting 36 Socioeconomics In 2025, we completed around 99% of the individual out-of-court settlements for Brumadinho and the Paraopeba Basin, with accumulated payments amounting to approximately BRL 4 billion made to 17.5 thousand people. Only isolated and additional cases related to the restrictions on the use of the Paraopeba River remain. Socio-economic reparations combine compensation with structural investments in sanitation, water supply security and essential services. A total of 4.4 billion liters of water were distributed, and 694 supply stations—including systems, treatment plants, and alternative solutions—were installed, benefiting communities in the Paraopeba Basin and other river basins. In Córrego do Feijão, the Territory Resignification Program is advancing the transition toward a park-territory model, integrating income generation, sustainable agriculture, and tourism. In 2025, the participating enterprises increased their level of maturity in management and marketing by 54% and recorded an 84% increase in turnover compared to 2024. A 2-hectare Agroforestry System now integrates production, environmental conservation and income. In 2025, the Brumadinho Tourism Program made progress in consolidating an ecosystem aimed at strengthening local tourism and sustainable development. During this period, the Céu de Montanhas Association and the www.experimentebrumadinho.com.br digital platform were set up, increasing governance, community coordination and visibility of the region. In the last 12 months, the initiative has shown significant financial results, with revenues of BRL 5.5 million and direct income generation of BRL 1.30 million. Under the Judicial Settlement for Comprehensive Reparation— (AJRI, in portuguese), by the end of 2025, BRL 34.9 billion had been disbursed: BRL 7.4 billion in obligations to perform, BRL 21.3 billion in judicial deposits, and BRL 6.3 billion in actions already undertaken prior to the agreement, resulting in 81% of the total amount fulfilled. Among the socioeconomic obligations to perform, 425 projects were approved, of which 113 were completed and validated by the socioeconomic auditor of the agreement, 3 were completed iand are awaiting the socioeconomic audit, 123 were converted into obligations to pay and amounts have already been settled, and 186 are in progress. Socio-environmental In 2025, the socio-environmental front concentrated its efforts on completing tailings management, recovering degraded areas and monitoring water, biodiversity and health risks. 12.2 million m³ of tailings in the main affected area, the "hot zone" of the Ribeirão Ferro-Carvão Sub-Basin, were removed. Within the broader framework of environmental recovery in Brumadinho, 79 hectares were restored in 2025, distributed across Atlantic Forest compensation areas, areas of permanent preservation and the planting of endangered species, and the main area impacted by the collapse of the Ribeirão Ferro-Carvão basin. Since 2019, approximately 264 thousand seedlings have been planted; together with this effort, we have to date reached a total of 257 hectares undergoing environmental restoration. Monitoring of water quality in the Paraopeba River indicates a positive trend, with reduced concentrations of metals associated with the dam breach—particularly manganese and total iron— and stabilization of turbidity levels, especially in the most affected stretches and up to the Igarapé In January 2026, the Minas Gerais Fire Department ended the search for the two victims that had not yet been identified after surveying more than 11 million cubic meters of tailings. With the conclusion of this stage, the work the work is now being led by the Civil Police, which, since then, has remained responsible for the identification process, through forensic analysis of the materials already located and those still under evaluation evaluated.

Studies of the biota have recorded 19 plant species and 14 terrestial animal species that are threatened with extinction, as well as 118 fish species, of which 99 are native and six have some degree of extinction threat, indicating a return to favorable environmental conditions. In the Paraopeba Basin Socio-Environmental Reparation Plan (PRSA, in portuguese), 12 plans, programs and projects had been approved by the end of 2025. This information is available on the socio-environmental audit portal. Among the highlights is the Education Professionals Training Project (PEABP, in portuguese), whose implementation agreement was signed with the Federal University of Ouro Preto (UFOP), strengthening the educational network across the municipalities. Institutional relations and communities In 2025, we intensified dialogue and transparency with communities through structured engagement programs. The Community Engagement Program developed 96 initiatives, with 12,249 participants, including conversation circles, workshops and thematic meetings. The Hack Projetos initiativetrained leaders from nine municipalities over a six-month period and awarded three initiatives with seed funding and mentoring to help secure additional resources. We engaged not only with local communities but also with investors, authorities, judicial bodies, and specialists—hosting delegations interested in the reparation experience and participating in forums, conferences, and discussions on reparation and socio-environmental risk management. Rupture of Samarco's Fundão Dam, Mariana, 2015 On October 25, 2024, the involved companies, federal, state and municipal governments, and judicial institutions signed the Comprehensive and Definitive Reparation Agreement addressing the damage caused by the rupture of the Fundão dam in Mariana, Minas Gerais, Brazil, on November 5, 2015. The Agreement provides for a total financial value of approximately BRL 170 billion1, of which BRL 73.1 billion had already been disbursed from 2015 to December 2025. This total amount includes past and future obligations to pay and to perform, previously conducted by the now liquidated Renova Foundation, which have been replaced by definitive reparation actions under the responsibility of Samarco and the public authorities to assist the people, communities and environment impacted by the dam collapse. The Agreement established three main lines of obligations: Amount (on a 100% basis) Main obligations BRL 100 billion Payments made in installments over 20 years to the federal government, the states of Minas Gerais and Espírito Santo, and affected municipalities to fund programs and compensatory actions tied to public policies.2 BRL 32 billion Samarco's obligations to perform, including individual compensation, resettlement and environmental recovery initiatives.

Our Bylaws separate the roles of Chairman of the Board, elected by the General Shareholders’ Meeting, and CEO appointed by the Board of Directors. The former is dedicated to the company's strategic agenda, overseeing and supporting actions, while the latter leads the company's operations to achieve the best possible results. Both roles converge on a single objective: to ensure the conditions needed to build the Vale of tomorrow—a corporation with high standards of corporate governance, recognized by society as a benchmark in safety and the most reliable Our management model VALE | 2026 Annual and Extraordinary Shareholders Meeting 42 operator in its industry, people‑focused and leading value creation in mining through ethical and sustainable practices. Our Bylaws also stipulate that if the elected Chairman of the Board is a non-independent director, the elected independent members must appoint an independent director to act as Lead Independent Director (LID), providing an alternative channel of contact with our investors. Since 2023, Mr. Daniel André Stieler has been acting as the Chairman of the Board, while Mr. Manuel Lino Silva de Sousa Oliveira as the LID1, with Vale pioneering the implementation of this position in Brazil. Under our Bylaws, the Board of Directors must comprise between 11 and 13 members. It currently has 13 members, including 8 independents— exceeding the Bylaws' minimum of 7 independent directors and well above the requirements of B3's Novo Mercado regulations. In addition, among the members of the Board, one (1) member and their alternate are elected in a separate vote by all the company's employees. Vale's Fiscal Council must be composed of 3 (three) to 5 (five) effective members and their respective alternates. Under the terms of the Company's Bylaws, the holder of the special class preferred shares (golden shares) is ensured the right to elect and dismiss, in a separate vote, one (1) effective member of the Fiscal Council and their respective alternate.

VALE | 2026 Annual and Extraordinary Shareholders Meeting 58 Our Executive Risk Committees and Conduct and Integrity Committee The Company’s risks are mapped, assessed, and monitored in alignment with its governance structure and risk appetite, enabling the implementation of appropriate preventive and mitigating measures to support the achievement of organizational objectives and optimize performance, with a strong focus on safety. The general risk management guidelines governing our business are established by the Board of Directors. The Executive Committee is responsible for implementing these guidelines. The Executive Committee has the support of five Executive Risk Committees that are divided according to their scope of action, as follows: 1) operational, 2) geotechnical, 3) strategic, financial and cyber, 4) compliance and institutional relations, 5) sustainability and communications. These committees are non-statutory advisory bodies whose mission is to advise Vale's Executive Committee—the Company's primary management body—on risk monitoring and in the necessary deliberations of this collegiate body, in accordance with Vale's Risk Management Policy. The main responsibilities of these committees are, among others: a) Promote the Risk Management Culture in the company; b) Issue preventive recommendations regarding the potential risks addressed in the meetings of the aforementioned Committees, as well as to define those responsible for monitoring such recommendations; c) Recommend improvements in the risk management process, whenever applicable. The Company also has a Conduct and Integrity Committee, set up by the Board of Directors to promote the Ethics & Compliance Program and compliance with the Company's Code of Conduct. Our ESG governance In a dynamic environment and recognizing our high dependence on natural resources, it is crucial that our leaders are prepared to address challenges that go beyond operational and financial issues, also encompassing environmental, social and governance (ESG) aspects. The guidelines that govern our actions are defined by the Board of Directors, monitored by the Sustainability Committee and executed by the Executive Committee considering various socioenvironmental issues, such as climate and human rights. The Executive Vice President for Sustainability is responsible for ensuring continuity and advancing the implementation of policies and guidelines, addressing critical issues, and evaluating socioenvironmental investments, among other responsibilities, thereby contributing to the execution of our strategy to generate a positive impact for people and nature. It is worth noting that at least 25% of the variable compensation of the Executive Committee members is linked to ESG targets, i.e. unrelated to economic-financial or production metrics and aligned with our ambition to make Vale a leader in sustainable mining. VALE | 2026 Annual and Extraordinary Shareholders Meeting 59 Our information security Our information security risk management is part of our risk management model. In this context, the Board of Directors is primarily responsible for overseeing risk management processes, including cybersecurity. In support of our Executive Committee, there is an Executive Risk Committee dedicated to managing strategic, financial and cyber risks, which monitors and recommends preventive actions on potential information security risks. Vale's Cybersecurity role is led by our Chief Information Security Officer (CISO), within the office of the Technical Executive Vice President. The CISO regularly informs the Audit and Risks Committee of the Board of Directors, as well as the Executive Committee for strategic, financial and cyber risks about our cybersecurity and information security posture. The update includes a risk assessment conducted by independent third-party cybersecurity experts to evaluate the structure of our cybersecurity program and test the effectiveness of our processes. This assessment is conducted based on the NIST Cybersecurity Framework and our cyber score, as measured by an independent security rating platform (www.securityscorecard.com). These two committees are also informed about cyber incidents, even if they are considered immaterial. Our security practices include continuous monitoring through the Security Operations Center, which processes billions of telemetry events to detect anomalies across our systems. We maintain a robust cyber incident response plan, updating procedures and recovery plans, as well as carrying out simulations to educate and prepare operational, tactical and executive audiences for real incidents. Should a material cyber incident occur, it will be addressed by the Cyber Crisis Corporate Committee, with the Executive Committee and the Board of Directors kept informed to enable public disclosure, where applicable. Our cybersecurity risk management covers the identification and oversight of risks related to third-party service providers and third-party platforms. This includes contractual agreements to meet minimum security requirements and the use of independent risk assessment platforms. Each year, we conduct training and awareness initiatives focused on cyber risks and best practices for employees and contractors. We emphasize that our business strategy and results have not been materially affected by cyber threats over the past three years, however, this does not constitute a guarantee against potential future impacts. VALE | 2026 Annual and Extraordinary Shareholders Meeting 60 Artificial intelligence Our Board of Directors is aware of the rapid advancement of artificial intelligence (AI), which presents both opportunities for growth and challenges that must be considered. These challenges include the absence of a globally harmonized regulatory framework, potential impacts on people management, and the use of AI to enhance the sophistication of cyber threats, among other developments. The Board of Directors, through the Audit and Risk Committee, together with the Executive Risk Committees, addresses AI-related risks within the scope of their responsibilities for overseeing risk management processes. Despite these challenges, Vale has strategically invested in the adoption of AI to enhance operational efficiency, safety, and sustainability across its operations, reinforcing its position as a benchmark for innovation in the mining industry. AI is applied in initiatives such as the Intelligent Mine project, which optimizes the operation of offroad trucks by determining, in real time, the optimal speed for each section of the mine. This initiative contributes to reducing diesel consumption, increasing energy efficiency and improving productivity, and is part of the Company's strategy to decarbonize and modernize its operations. In addition to operational gains, AI has played a key role in risk management, especially in the field of cybersecurity. Vale leverages advanced AI- and machine learning–based technologies for cyber threat protection, detection, and monitoring, strengthening its controls and response capabilities in the face of increasingly sophisticated digital attacks. These tools enable the quick identification and mitigation of unauthorized access attempts, digital fraud and other threats, protecting sensitive information, critical systems and ensuring business continuity. In monitoring dams and geotechnical structures, AI combined with satellite technologies enables continuous, real‑time observation of the main structures.

Item III - Setting the annual global compensation of management and Fiscal Council members for the year 2026 VALE | 2026 Annual and Extraordinary Shareholders Meeting 74 With regard to the Committees and Advisory Committees, the 2026 proposal essentially considers maintaining the assumptions in force in 2025 with occasional adjustments to the compensation and collegiate bodies' composition. This proposal stipulates that the monthly compensation of each Fiscal Council member corresponds to at least 10% (ten percent) of the fixed compensation that, on average, is attributed monthly to each Executive Committee member, not including benefits, representation fees and profit sharing.

It is understood that alternate members shall only be compensated if they are holding office due to a vacancy, impediment, or absence of their respective alternate member. The 11% reduction for the Executive Committee (CEO and Executive Vice Presidents) is mainly due to the absence of provision for termination payments.

None of the plans extend to board members or provide for the granting of options to purchase company shares. Long-term incentive - Vale Performance Shares Program (PSU) The PSU is a three-year cycle program designed to incentivize top management (from General Managers to Executive Committee members) to create sustainable value, aligning executive performance with shareholder vision. At the start of the cycle, four elements are considered when calculating the number of units to be awarded to each participant: Beginning of the PSU cycle BRL 100,000.00 base salary as of 31 Dec of the previous year A B C D Nº of shares 9.00 reference value for VP in Brazil BRL 75.00 (1-27.5%) weighted price VALE3 60 trading sessions previous year income tax rate estimated in Brazil 8,700 net number of shares Example of initial calculation, with hypothetical values: ¹ Base salary represents the monthly salary paid to employees based in Brazil and the annual salary for employees based abroad.

TSR measures the return that an investment provides to the shareholder, considering the fluctuation in the share price and the distribution of dividends, based on a period. TSR Final price1 Initial price2 Dividends dividends or interest on capital distributed in the period Initial price2 1 Weighted average price by volume traded in the 30 days of trading prior to the closing date. 2 Weighted average price by volume traded in the 30 days of trading prior to the opening date.

VALE | 2026 Annual and Extraordinary Shareholders Meeting 85 At the end of the cycle, three years after its commencement, eligible participants will receive the award in the form of Vale’s common shares: (i) the amount equivalent to at least the same number of shares granted in the cycle, multiplied by the performance factor calculated, and (ii) virtual dividends relating to the same number of shares calculated in item (i).

It is an essential indicator for analyzing how the company allocates capital and makes a profit from it. In general terms, the higher the index value, the greater the return generated for shareholders by the Company. The second indicator incorporates ESG elements into overall performance: Indicators Cycles starting in 2024 and 2025 Health and safety weight: 10% The indicator will be measured based on the absolute number of incidents resulting in fatalities and/ or changed lives and recordable injuries with high potential (N1 + N2). It is intended to reinforce the importance of health and safety, in line with Vale’s strategy to reduce fatalities and high-potential injury events. Sustainability weight: 15% Indicators related to the Sustainability topic consisting of: reduction of greenhouse gas emissions (10%) and ESG Restrictions (5%), included from the year 2025. This target is aimed at reducing ESG investment restrictions in Vale, i.e. removing Vale from institutional investor restriction lists based on ESG criteria. This indicator replaced the DJSI (Dow Jones Sustainability Index) which was in force until 2025.

It is designed to attract and retain talent while reinforcing a culture of longterm, sustainable performance. Leadership (Coordinators through Executive Committee members) who acquire company shares with their own resources and hold them for the duration of the cycle become eligible to receive a share-based bonus at the end of the three-year period. Participation and retention of shares is compulsory for the Executive Committee and voluntary for the others appointed to take part in the program. For purposes of determining the number of shares each participant may receive at the beginning of the cycle, the following criteria are considered: Continuing with the initial calculation example, with hypothetical values for the 2023 cycle, the final value would be: End of the PSU cycle 8,700 shares 8.71% payout BRL 84.48 (1 - Income Tax rate 27.5%) 88,298 The program also provides for the payment of virtual dividends, with the delivery of additional shares, based on the unit price, according to the payment made by Vale to the market during the cycle, and the program's performance.

The Matching Program makes payments relating to virtual dividends, calculated on the basis of (i) the shares not yet settled by the plan, and (ii) the amount of dividends and/or interest on equity per share, as paid by the Company to shareholders in the period of the cycle. Virtual dividends are paid in cash, at a time close to Vale's payment to shareholders in general. Continuing the example of the initial calculation, with hypothetical values, the final value would be: End of the Matching cycle 8,000 initial shares VALE3 60.00 (1 - Income Tax rate 27.5%) BRL 662,069.00 gross payout of The program also provides for the payment of virtual dividends based on the unit price as paid by Vale to the market during the cycle. VALE | 2026 Annual and Extraordinary Shareholders Meeting 88 • Stock Ownership Guidelines: This rule requires the maintenance of a minimum shareholding equivalent to 36 times the fixed monthly compensation for the CEO and 24 times the fixed monthly compensation for the Executive Vice Presidents. Executives may build up these minimum shareholding levels over the course of their mandates through participation in the Matching and PSU programs and are prohibited from trading any shares held until the required minimum shareholding has been achieved. • Malus and Clawback: These are rules used by the Board of Directors, in the event of facts or events of exceptional severity, which make it possible to eliminate, reduce or obtain the return (in part or in whole) of the variable compensation scheduled for payment or of installments already paid to executives. Although the Company had already adopted a Clawback provision applicable to members of the Executive Committee, a formal Clawback Other executive compensation practices Policy was established in 2023. The policy defines the circumstances under which executives may be required to return incentivebased compensation to the Company, in accordance with SEC requirements. • Evaluation of the Total Compensation package: each year, a compensation review process is conducted for the members of the Executive Committee, during which individual remuneration is discussed and evaluated by the Board of Directors. This process considers the individual performance assessment results, market benchmarking, and alignment with the Company's Career and Succession strategy. The Performance Factor for each individual is determined by the Board of Directors and directly influences the amount of the annual bonus paid, as well as the potential application of merit-based and differentiation measures for each executive. Individual feedback and development actions are conducted with each person at the end of the process. In 2025, as approved by the Board of Directors in January, the performance assessment process for the Executive Committee was enhanced to include revisions to the evaluator framework (360º), updates to the evaluation criteria, and the introduction of a mid-year review for the CEO. It also incorporated greater alignment in the determination of the Performance Factor with the company’s overall results, making the model more effective and closely aligned with the Company's strategic plan. • Termination policy: the termination package for members of the Executive Committee is defined by the Board of Directors based on market benchmarks and adjusted on an individual basis to ensure that compensation is commensurate with the complexity of the position, the executive’s level of experience, and performance in the role. Short-term and long-term incentive payment is made in proportion to the period worked.

The increases projected for 2026 are reflected in the “variables and shares” categories, primarily driven by the appreciation of the VALE3 share price, which impacts the cost of the 2026 Matching and PSU grants, as well as by higher projected results for the 2024 and 2025 PSU indicators.

It also considers attracting executives with highlevel professional qualifications and skills that are critical to Vale's challenges. In preparing the proposal, the Board of Directors was supported by two committees: The People and Compensation Committee (which evaluates the compensation strategy of the Executive Committee and the proposal for the allocation of the total annual compensation for managers) and the Nomination and Governance Committee (which reviews the compensation strategy of the Board of Directors, its Advisory Committees and Fiscal Council). Board of Directors' comments on the proposal VALE | 2026 Annual and Extraordinary Shareholders Meeting 92 The Fiscal Council is a permanent body, made up of 3 to 5 members and the same number of alternates, who will serve until the first Annual General Meeting to be held after their election, in accordance with the legislation in force and Vale's Bylaws. The number of vacancies will be determined by the shareholders at the Shareholders' Meetings, since this decision is not up to the Company's management. The Company informs that, as of the date of publication of this material, it has received communications from shareholders nominating candidates for election to the Fiscal Council, as follows: Item IV - Election of the Fiscal Council members Any nomination of candidates for membership of the Fiscal Council by shareholder(s) holding common shares and holders of American Depositary Receipts (ADRs) issued by Vale must comply with the applicable legal provisions, including those set forth in the Brazilian Corporations Law, CVM Resolution No. 81, and Circular Letter/Annual-2026-CVM/SEP. Shareholders holding common shares and holders of ADRs may include candidates for members of the Company's Fiscal Council in the Remote Voting Ballot ("Ballot") by sending a written request to the Executive Vice President of Finance and Investor Relations at assembleias@vale.com, accompanied by proof of shareholding and/or ownership of ADRs, a copy of the complete representation documentation and the candidate(s) indicated, provided that the minimum percentage of participation (equivalent to 0.5% of the Company's share capital) and the other procedures and requirements set out in CVM Resolution No. 81 and CVM Resolution No. 80 are complied with. According to CVM Resolution No. 204 (“Resolution 204”), which came into force on January 2, 2025, shareholders may submit such request up to 25 days prior to the date of the General Meeting (in this case, April 5, 2026), and the Company has up to 20 days prior to the date of the General Meeting (in this case, April 10, 2026) that has the election of members of the Fiscal Council on its agenda to resubmit the Ballot, with the objective of including candidates for such body who are nominated by shareholders holding at least 0.5% of the shares issued by the Company and who comply with the requirements applicable to the request, as described above. The ADR Program Deposit Agreement provides that the information needed to prepare the proxy cards for voting by ADR holders must be sent no later than 30 days before the Meetings. Considering the terms of the ADR Program Deposit Agreement and the procedures practiced by the depositary bank of the ADR program, JP Morgan Chase N.A, and other service providers involved in the process for the preparation and distribution of proxy cards for voting by ADR holders on the matters on the agenda of the AGM, the Company has been informed that it will not be possible to resubmit the proxy cards to ADR holders within 20 days prior to the AGM, the deadline for resubmitting the Ballot, as provided for in Resolution 204.

VALE | 2026 Annual and Extraordinary Shareholders Meeting 93 Notwithstanding the 30-day period provided forth in the Deposit Agreement and the three (3) business day period provided for in Article 39 of CVM Resolution No. 81, the Company will make reasonable efforts to include in the AGM proxy cards requests for the inclusion of candidates for the Fiscal Council in the Ballot, in accordance with the above provisions, that have been received by the Company by April 5, 2026, provided that such requests comply with the aforementioned terms and are duly accompanied by the correct and complete applicable documentation, as required by CVM Resolutions 80 and 81, since on April 7, 2026, the depositary will begin the process of preparing and distributing the proxy cards. Any requests that are not duly accompanied by the correct and complete documentation may not be included on the proxy cards for the AGMs, and there will not be sufficient time to complete such proxy cards; this is without prejudice to the possibility of correcting those requests for the purpose of including the nominated candidates only in the Ballot. Therefore, the Company recommends that shareholders who intend to request the inclusion of Fiscal Council candidates in the Ballot submit the request, accompanied by the correct and complete applicable documentation, as soon as possible, in order to allow the inclusion of such candidates both in the Ballot and in the proxy cards of the AGMs. However, even in the event that there is no time to include requests in the proxy cards of the AGM, ADR holders may cancel their ADRs and receive the corresponding number of shares issued by Vale, in accordance with the rules, deadlines and payment of fees established by the depositary bank of the Vale ADR Program, under the terms of the Deposit Agreement. In this context, already as a shareholder of the Company, they may vote at the AGMs either by Ballot or by virtual participation via digital platform, in accordance with the rules established in CVM Resolution 81, the Call Notice and this Statement. The Board of Directors has no recommendation for this item. Board of Directors' comments on the proposal In addition to the aforementioned nominations, the Company received, on February 27, 2026, the nomination to reelection, by the sole holder of preferred shares issued by Vale, of Mr. Dario Carnevalli Durigan and Rogerio Ceron de Oliveira, to the positions of full member and alternate member of the Fiscal Council, respectively. We note that, pursuant to Vale’s Bylaws, the holder of the golden share is entitled to elect and remove one member of the Fiscal Council and the respective alternate, in a separate voting process1. In addition to the information above, in order to deliberate on this item, the Company recommends reading items 7.3 to 7.6 of the FRE (article 11 of CVM Resolution 81), which can be found here, based on the data provided by the shareholders who indicated them. 1 The separate election of a member and his or her alternate by the Union to the Fiscal Council is provided for in the Company's Bylaws. It should be noted that the Fiscal Council is an oversight body, not a deliberative one, and therefore the separate election of the golden share does not represent direct interference in the Company's decisions. Each common share and each golden share issued by Vale confers one vote at the shareholders' meeting, in ordinary deliberations, preserving the “one share, one vote” rule for such matters. The special rights associated with golden shares are expressly and specifically provided for in the Bylaws and are limited to certain matters, and should not be confused with a plural voting system or any expansion of voting power in ordinary resolutions. VALE | 2026 Annual and Extraordinary Shareholders Meeting 94 Management's proposal for items for resolution at the Extraordinary General Meeting Item I—Ratify the appointment of Mr. Marcio Antônio Chiumento as an effective members of the Board of Directors in accordance with Paragraph 9 of Article 11 of the By-Laws On February 20, 2026, Mr. João Luiz Fukunaga resigned as a member of the Board of Directors. In accordance with the provisions of Vale's Bylaws and Directors' Policy, as well as the applicable legal guidelines, on February 26, 2026, the Board of Directors approved the appointment of Mr. Márcio Antonio Chiumento for the vacant position, by election at the Extraordinary General Meeting. To this end, the proposal is to approve the ratification of the appointment of Mr. Márcio Antonio Chiumento for the position of member of the Board of Directors, to fulfill the unified term of office of the current composition of the board, i.e. until the Annual General Meeting to be held in 2027. In order to deliberate on this item, the following are made available to the Shareholders: • Information and documents of Mr. Márcio Antonio Chiumento, in accordance with items 7.3 to 7.6 of the Reference Form (available here), as set out in Articles 37 and 38 of CVM Resolution No. 81 and Annual Circular Letter CVM/SEP 2025. • Extract of the Minutes of the Board Meeting dated February 26, 2026, which resolved on the appointment of the director, already disclosed to the market and available at this link. • Profile with the candidate's CV and mapped skills, based on the Board of Directors' Skills Matrix, available below. The Board of Directors recommends approval of this item. Board of Directors' comments on the proposal VALE | 2026 Annual and Extraordinary Shareholders Meeting 95 Márcio Antonio Chiumento Main experience: Mr. Márcio Chiumento holds a degree in Law from UPPR, an MBA in Financial Business from UFRS and a Masters in Management and Innovation from UPPR. He is currently serving as President of Previ and is responsible for the strategic and institutional management of the entity, focusing on economic and financial soundness and the long-term sustainability of the benefit plans. He has more than two decades of experience at Banco do Brasil, with an executive career in the areas of strategy, innovation, service channels, finance and governance. His main professional experience in the last 5 years include: (i) President of Previ (2025-current); (ii) Director of Participations of Previ (2024-2025); (iii) Head of a Strategic Unit of Banco do Brasil (2023-2024), (iv) General Ombudsman of Banco do Brasil (2022-2023); (v) Executive Manager in the Channels and Client Department of Banco do Brasil (2019-2022); (vi) He serves on boards and committees of companies such as Neoenergia, Tupy, Cielo, BB Previdência and Ativos S.A. Director appointed by the Board of Directors Shareholder nomination: • Caixa de Previdência dos Funcionários do Banco do Brasil—Previ. Skills, knowledge and expertise: • Investment portfolio management; • Innovation and RD&I; • Finance; • Management of financial, operational and regulatory risks; • Corporate and fiduciary governance; • M&A and corporate restructuring; • Executive leadership; • Project Management. Mr. Márcio Antônio Chiumento will formally be classified as a non-independent director in accordance with the Company's adopted criteria. Nonetheless, his election does not alter Vale's current governance structure, which maintains a majority of independence on the board, at 62%, in line with international best governance practices. Mr. Chiumento's skills complement the critical knowledge and skills of Vale's board of directors, reinforcing the board's diversity of experience and adherence to the Company's strategic needs. VALE | 2026 Annual and Extraordinary Shareholders Meeting 96 In order to rationalize Vale group's corporate structure, and in line with the Company's organizational streamlining process, it proposes the approvals of the mergers of the whollyowned subsidiaries Baovale and CDA by Vale. Vale already owns 100% of the shares issued by Baovale and CDA, therefore the proposed mergers will not result in a capital increase or the issue of new shares in the Company. Vale's Board of Directors approved the aforementioned merger proposals, without reservations by the Fiscal Council, at its meeting held on February 26, 2026. In addition, the Board of Directors recommends reading the complete documentation on the mergers, which includes: (i) the Protocols of Justification, (ii) the Valuation Reports of the Accounting Net Equity of the companies; (iii) the proposals for the provision of services by the appraiser; (iv) Annexes I and L of CVM Resolution 81, as well as the Minutes of the meeting of the Board of Directors and the opinion of the Fiscal Council. All of these documents are available at the links below. The Board of Directors recommends the approval of the mergers of Baovale and CDA by Vale, with the respective approval of items 2.2 to 2.5 of the Call Notice, as approved by the Fiscal Council. Board of Directors' comments on the proposal II. Approve the Protocols and Justifications for the Merger of Baovale Mineração S.A. (“Baovale”) and CDA Logística S.A.

Approve the Valuation Reports of Baovale and CDA prepared by Macso, and V. Approve the mergers of Baovale and CDA into Vale, without a capital increase and without the issue of new shares. The complete documentation of the proposal for the merger of CDA by Vale is available here. CDA The complete documentation of the proposal for the merger of Baovale by Vale is available here. Baovale VALE | 2026 Annual and Extraordinary Shareholders Meeting 97 Item VI—Approve the amendment to the heading of Article 5 of the Bylaws to reflect the new number of capital shares (4,439,159,764) and common shares (4,439,159,752), due to the Vale’s cancellation of 99,847,816 common shares. On March 12, 2026, the Board of Directors approved the cancellation of 99,847,816 common shares issued by Vale that were in Treasury, arising from the Share Buyback Programs approved on April 27, 2022 and October 26, 2023. The number of shares canceled corresponds to 36.9% of the total amount held in treasury. Accordingly, the proposal is to amend the caput of Article 5 of Vale's Bylaws to reflect the cancellation of the aforementioned 99,847,816 common shares issued by Vale, as approved by the Board of Directors. The Board of Directors recommends approval of this item, as approved by the Fiscal Council. Board of Directors' comments on the proposal In order to deliberate on this item, the following are made available to the Shareholders: • Extract of the Minutes of the Board meeting and the Opinion of the Fiscal Council on the proposed cancellation of shares. • Table detailing the origin and justification of the proposed changes, with their legal and economic effects, as well as a copy of the bylaws containing, in highlight, the proposed changes considering the cancellation of shares, under the terms of Article 12, I and II of CVM Resolution 81. VALE | 2026 Annual and Extraordinary Shareholders Meeting 98 Item VII—Approve the increase of Vale’s share capital, without the issuance of shares, in the total amount of BRL 500,000,000.00, raising the Company's share capital to BRL 77,800,000,000.00, through the capitalization of part of the Income Tax Incentive Reserve, carried out in the areas of the Superintendence for the Development of the Amazon (SUDAM), and the consequent amendment to the caput of Article 5 of Vale's Bylaws. In order to deliberate on this item, the following are made available to the Shareholders: • Information on the capital increase, pursuant to Annex C of CVM Resolution 81; • Table detailing the origin and justification of the proposed changes, with their legal and economic effects, as well as a copy of the bylaws containing, in highlight, the proposed changes considering the capital increase, under the terms of Article 12, I and II of CVM Resolution 81. • Extract of the Minutes of the Board meeting and the Opinion of the Fiscal Council on the proposed capital increase As a condition for benefiting from the tax incentive provided for in Article 523 of the current Income Tax Regulations (RIR), the amount of income tax not paid as a result of the exemption or reduction may not be distributed to shareholders and must instead be recorded in a reserve that may be used exclusively to increase share capital or to offset losses. The new CONDEL/SUDAM Resolution No. 136/2025 set the deadline for incorporating funds from tax incentives for reinvestment into the companies' capital, which is 180 days from the end of the fiscal year in which the release letter was issued by the Superintendence for the Development of the Amazon (SUDAM). To comply with the aforementioned legal provisions, the Company proposes to increase Vale’s share capital, without the issuance of new shares, in the total amount of BRL 500,000,000.00, through the capitalization of a portion of the Income Tax Incentive Reserve related to operations carried out in the SUDAM areas, with the corresponding amendment to the caput of Article 5 of the Bylaws. Of the above-mentioned amount, BRL 466,203,751.55 corresponds to the total balance of the reinvestment tax incentive account already released by SUDAM for the years 2011 to 2017, as required by CONDEL/SUDAM Resolution No. 136/2025. The remaining amount, for purposes of rounding the capital increase, corresponds to a portion of the tax incentive reserve related to the 75% reduction in Corporate Income Tax (IRPJ) for 2014. This involves transferring amounts within equity itself, from the Tax Incentive Reserve accounts to the Share Capital account, without issuing new shares and, therefore, without diluting shareholder stakes. The Board of Directors recommends approval of this item, as approved by the Fiscal Council.
