Climate Change: Refers to a change in the state of the climate that can be identified (e.g., through statistical tests) by changes in the mean and/or variability of its properties, and that persists for an extended period, typically decades or longer. These changes may be attributed to internal natural processes of the climate system or external forcings, such as solar cycle modulations, volcanic eruptions, and persistent anthropogenic changes in atmospheric composition or land use. Critical Regions: Regions where Water Resources are under greater pressure, whether due to scarcity, quality, use conflicts, climate vulnerability, and/or impacts resulting from human activities, requiring specific management strategies, prioritization of actions, and strengthening of operational water resilience. Efficient Water Use: Use of a smaller volume of water in operational processes while maintaining productivity, through the adoption of technologies and practices aimed at promoting water efficiency, prioritizing the reduction of conventional source use and expanding the utilization of sustainable sources, such as reuse, rainwater harvesting, and renewed water. Employees: Any employee of Vale and/or Subsidiaries, permanent or temporary, interns, apprentices, and/or trainees. Hydrological, Climatic, Physical, and Socioeconomic Context of Watersheds: Refers to the natural and anthropogenic characteristics of Watersheds, including rainfall regime, flows, temperature, humidity, climate variability, relief, geology, land use and occupation, water availability, and multiple water uses, as well as socioeconomic conditions. Impact Management: Apply the mitigation hierarchy to avoid, minimize, mitigate, and/or compensate for potential negative socio-environmental impacts resulting from the Company's activities and act to enhance positive impacts, as defined in the Sustainability Policy, "POL 019-G." Leverage Positive Outcomes for Nature: For the purposes of this policy, through investment in restoration, environmental conservation, nature-based solutions, and research, development, and innovation, drive positive outcomes for biodiversity, climate, water, and people, based on engagement and empowerment of local communities, including Indigenous Peoples and traditional communities, and partnerships beyond our borders. Contribute to discussions on transformative external agendas that seek to promote positive outcomes for nature. Operational Excellence: For the purposes of this Policy, specifically regarding water and Water Resources, it includes managing water aspects by fostering the implementation of effective controls, preventive actions, incorporation of practices to reduce the use of conventional water sources, and expansion of the use of sustainable sources. Operational Water Aspects: Characteristics of the Company's activities, products, or services that may interact with Water Resources, encompassing everything the Company consumes, generates, emits, or intervenes in the water environment. Includes abstraction (surface and groundwater), dewatering, use, consumption, storage, reuse, disposal, and treatment of water and effluents, as well as water replenishment. Also considers associated impacts, such as flow alterations, pressure on water sources, risks to water quality, and maintenance of multiple uses. Qualified Person in Water Resources (QP): Employee dedicated to Water Resources issues, with a systemic view of the operational unit or complex, responsible for integrating water management into the Company's various cross-functional areas. Responsible Water Resources Management: Rational, socially equitable, environmentally sustainable, and economically viable water use, achieved through an inclusive process involving Stakeholders, considering the Watershed and local impacts of Climate Change. Risk: The effect of uncertainty on organizational objectives, which manifests in many ways and can potentially impact all business dimensions, as defined in the Risk Management Policy, "POL-0009-G." 3 Water and Water Resources Policy POL-0032-G Rev.: 01 - 17/11/2025 DDE 095/2025 PUBLIC Stakeholders: For the purposes of this Policy, these include communities, media, investors, Employees, public agencies, Non-Governmental Organizations (NGOs), academia, Clients, Suppliers, and other companies.

Water Target 2030: A goal aimed at reducing, per ton produced, the abstraction of freshwater from conventional sources used in Vale's operational processes, aligned with the concept of operational water efficiency and the UN Agenda 2030 SDGs, prioritizing regions with higher Water Stress risk. Water Management Pillars: Four pillars: (i) governance: establishes responsibilities, policies, and regulatory compliance; (ii) monitoring and control: aims to ensure efficient water use; (iii) Water Risk Management: assesses physical, regulatory, and climate threats, promoting resilience; and (iv) stakeholder engagement: seeks to strengthen dialogue and collaborative solution-building, focusing on watershed-based management. Water Resources Structuring Plan 2030: Plan established in 2018 to guide the Company's strategic actions in each of the Water Management Pillars. The Plan also integrates socio-environmental2 goals voluntarily assumed by Vale and is aligned with various sustainability thematic axes.

Water Stress: Occurs when total water demand exceeds the available quantity during a given period, or when inappropriate water quality restricts its use. Watershed: The entire drainage area or natural catchment of rainwater, whose upper limit is the watershed divide (topographic divide), which enables surface runoff to the main channel and its tributaries, encompassing all existing water and land uses within its boundaries. 5.
