Rio de Janeiro, February 12th, 2026 Vale’s performance in 4Q25 and 2025 “In 2025, Vale delivered an outstanding performance, achieving or exceeding all guidances, while advancing strategic priorities that reinforce our long-term ambition. We strengthened our commitment to safety, with meaningful reductions in high potential incidents, while accomplishing an important milestone in our safety journey, by having no dams at emergency Level 3. In our operations, we reached the highest iron ore and copper production levels since 2018 and delivered double digit production growth in nickel. This strong operational performance was supported by improved asset reliability and the successful ramp up of key growth projects, like Capanema, Vargem Grande, VBME and Onça Puma. At the same time, we continued to enhance our cost competitiveness, capturing structural efficiencies that improve our position in the global industry cost curve. Our disciplined capital allocation, coupled with strong execution and a more favorable cycle, enabled us to deliver superior shareholder returns. As we enter 2026, we remain focused on operational excellence, sustainable growth through initiatives such as the New Carajás Program, and on delivering superior long-term value for all our stakeholders.", commented Gustavo Pimenta, CEO – 2 – Business Highlights Iron Ore Solutions • Vale has continued to advance the commissioning of the Capanema and Vargem Grande 1 projects, with full ramp-up expected in 1H26 and 2H26, respectively. The Serra Sul +20 project construction also continues to progress, having 84% physical progress, with start-up expected in 2H26. Vale Base Metals • Construction works at the Bacaba project began following the construction license approval. The project will extend the life of the Sossego Mining Complex, adding approximately 50 ktpy of copper over its 8-year mine life, with a total planned CAPEX of US$ 290 million. • Vale Base Metals entered into an agreement with Glencore to assess a brownfield copper development in the Sudbury Basin, targeting a future 50/50 joint venture. The project is expected to produce 880 kt of copper over 21 years with US$1.6–2.0 billion in capital, alongside additional nickel, cobalt, gold and PGMs, with a 1H27 investment decision. Recent developments • Vale has completed the repurchase of 23% of its outstanding participating debentures, totaling US$ 703 million, following the optional acquisition offer launched in October. Concluded in November, this transaction marks a key milestone in Vale's financial liability management. ESG Tailing Dams • Maravilhas II dam, Vargem Grande dam and Dam 6 had their emergency levels removed, following the approval by ANM. The structures received a positive Declaration of Stability Condition (DCE), confirming their structural safety. Since 2020, 27 dams were removed from emergency level status. • Campo Grande dam, at the Alegria mine in Minas Gerais, was eliminated, marking 63% completion of the Upstream Dam Decharacterization Program, with 19 structures eliminated since 2019. Climate & Social • COP30: Vale co‑led the Essential Mining Coalition, uniting 15 entities to outline a pathway to cut Brazil’s mining-related emissions by up to 90% by 2050. • Poverty: As part of Vale's ambition to help lift 500,000 people out of extreme poverty, Vale has created the Together Against Poverty program (Juntos contra a Pobreza) which treats poverty as a multidimensional phenomenon and one of the most urgent and complex social challenges of our time. The initiative mobilizes companies, social organizations, academia, civil society, and governments in a collaborative effort to strengthen public policy and create a lasting legacy for local communities. Reparation Brumadinho • The execution of the Brumadinho Integral Reparation Agreement continues to progress, with approximately 81% of the agreed-upon commitments completed by 4Q25 and in accordance with the deadlines outlined in the settlement. Mariana • The Samarco reparation program continues to advance, with R$ 73 billion disbursed as of December 31, 2025. Progress under the definitive compensation program (PID) remains strong, with ~304 thousand agreements signed by the end of 2025, showing steady advancement in resolving the underlying claims.

Proforma EBITDA and Proforma net income attributable to Vale's shareholders – Reporting practice To enhance transparency and comparability, Vale reports: • Proforma EBITDA - a metric that provides a clearer view of operational performance across periods. It comprises: (i) Adjusted EBITDA as defined in note 3 to Vale’s Interim Financial Statements, which is a required disclosure under IFRS 8 – Operating Segments; excluding (ii) Brumadinho-related and dam decharacterization effects, and (iii) non-recurring items. This metric is disclosed consistently and in compliance with CVM Resolution 156. For the reconciliation of EBITDA Proforma to Net Income, please refer to table above. • Proforma net income attributable to Vale's shareholders - a metric that provides a clearer view of earnings performance across periods. It excludes non-recurring items, such as asset impairments, as well as the related income tax effects. Financial Results – 4 – EBITDA Proforma EBITDA was US$ 4.8 billion in 4Q25, 17% higher y/y, mainly driven by (i) stronger copper and by-products reference prices, and (ii) higher sales volumes of iron ore and copper, which were partially offset by the negative impact of the BRL appreciation. Proforma EBITDA 4Q25 vs. 4Q24 - US$ million 1 Excluding Brumadinho expenses. 2 Including iron ore freight costs. 3 lncluding Associates and JVs EBITDA and others. Net Income Proforma net income totaled US$ 1.5 billion in 4Q25, 68% higher y/y, mainly driven by (i) an increase in Proforma EBITDA, (ii) impact of mark-to-market valuation of swaps on 4Q24 results, reflecting the 14% depreciation of the BRL at the end of that quarter. These positive effects were partially offset by a US$ 449 million increase in the Samarco provision, recognized in Associates & JVs result, reflecting updates related to the UK Claim, as well as the absence of a US$ 626 million gain recognized in 4Q24 from the acquisition of an equity interest in Minas-Rio, included in Results on disposal of non-current assets. Net income attributable to Vale’s shareholders totaled US$ -3.8 billion, a decline of US$ 3.4 billion y/y, reflecting (i) the effects mentioned above, (ii) US$ 3.5 billion impairment on Vale Base Metals's nickel assets in Canada, triggered by a downward revision in long-term nickel price assumptions based on market estimates and (iii) a US$ 2.8 billion reduction from a write-off of deferred tax assets from subsidiaries, recorded under Income taxes. Proforma net income 4Q25 vs. 4Q24 – US$ million 1 Including a variation of US$ 845 million in mark-to-market valuation of swaps. 2 Including variations of (i) US$ -504 million equity results, impacted by US$ 449 million of the Samarco provision adjustment, and (ii) US$ -44 million in EBITDA from associates and JVs. 3 Excluding a variation of US$ 1.5 billion related to Impairment and results on disposal of non-recurring assets. 4 Including variations of (i) US$ 254 million in Income taxes, (ii) US$ 228 million in Net income attributable to non-controlling interests, (iii) US$ -182 million in Streaming, (iv) US$ -135 million in Brumadinho and dam decharacterization, and (v) US$ -58 million in depreciation, depletion & amortization.

Revenues The average realized iron ore fines price was US$ 95.4/t, US$ 1.0/t higher q/q, mainly driven by higher iron ore reference prices (US$ 4.0/t higher q/q). This effect was partially offset by lower market premiums (US$ 1.0/t lower q/q) and the negative effect of pricing mechanisms adjustments (US$ 2.1/t lower q/q), mainly related to lagged prices adjustments. In the quarter, the Adjustments for FOB sales were positively impacted by the spot rates effect on freight pricing mechanisms.

Iron ore fines and pellets all-in costs, excluding sustaining investments, increased by US$ 4.8/t y/y, reaching US$ 54.3/t in 4Q25. This increase was mainly driven by lower all-in premiums (US$ 3.7/t lower y/y) and higher C1 cash costs, ex-third-party purchases (US$ 2.5/t higher y/y). These impacts were partially offset by lower freight costs (US$ 2.0/t lower y/y). For 2025, iron ore fines and pellets all-in costs, excluding sustaining investments, totaled US$ 54.2/t, below annual guidance of approximately US$ 55/t.

This increase mainly reflects (i) the negative impact of BRL appreciation, (ii) greater concentration of maintenance activities in the Northern System to improve performance and asset reliability, and (iii) higher production from the Southeastern and Southern Systems, which have a structurally higher cost base than the Northern System and therefore weighed on the production mix. These effects were partially offset by the positive impact of inventory turnover, driven by the consumption of inventories from the previous quarter at lower unit costs. For 2025, Vale’s C1 cash cost, ex-third-party purchases, totaled US$ 21.3/t, marking the second consecutive year of reduction (US$ 0.5/t lower y/y) and meeting the annual guidance of approximately US$ ~21.3/t.

Business Segments’ Performance – 13 – Vale's average maritime freight cost was US$ 18.0/t in 4Q25, US$ 5.9/t below the Brazil-China C3 route benchmark during the period, underscoring the effectiveness of Vale’s long-term affreightment strategy, which reduces both costs and volatility. Freight costs declined sequentially by US$ 0.8/t, mainly driven by lower bunker fuel costs (US$ 0.6/t lower q/q) and lower exposure to spot freight rates (US$ 0.3/t lower q/q). CFR sales totaled 65.6 Mt in 4Q25, representing 89% of total iron ore fines sales.

Pellets sales totaled 9.1 Mt, 3% higher q/q and 10% lower y/y, in line with the adjustments to production levels in response to current market conditions. The average realized iron ore pellets price was US$ 131.4/t, US$ 0.6/t higher q/q, as a result of a higher iron ore reference price (US$ 4.0/t higher q/q). This effect was partly offset by lower contractual pellet premiums (US$ 2.8/t lower q/q). Pellets’ cash costs per ton were 7% higher y/y, totaling US$ 77.6/t, primarily due to the combination of the negative impact of the BRL appreciation and higher unit costs in Oman operations given higher services costs in the period. FOB sales accounted for 58% of total pellets sales in the quarter.

All-in costs reached US$ -881/t in 4Q25, down US$ 1,979/t y/y, driven by higher by-product volumes and prices. These positive effects were partially offset by higher unit COGS. In 2025, all-in costs reached US$603/t, 77% down y/y. Unit COGS was US$ 5,749/t, up 10% y/y, reflecting the negative effect of BRL appreciation and higher mineral tax payments from the TFRM rate adjustment, introduced in March 2025. These effects were partially offset by higher dilution of fixed costs driven by higher production levels. Unit COGS, net of by-products, reached US$ -1,273/t, down US$ 1,757/t y/y, due to increased gold revenues, following higher gold prices and the increase in gold volumes sold in copper concentrates.

Revenues Net revenues totaled US$ 1.3 billion in 4Q25, increasing by 24% y/y, boosted by higher by-product prices (US$ 155 million) and higher sales volumes (US$ 15 million), which were partially offset by lower nickel realized price (US$ -57 million). The average realized nickel price was US$ 15,015/t, down 3% q/q, explained by a 1% decrease in the LME nickel price average. The average realized nickel price was 1% higher than the LME average, mainly due to the 67% share of Upper-Class I products in the North Atlantic mix, resulting in an overall positive impact of premiums of US$ 106/t.

Unit COGS, excluding external feed purchases, was US$ 21,204/t, declining by 14% y/y, underpinned by cost efficiencies at Voisey’s Bay and robust output at Long Harbour, which contributed to fixed cost dilution. Unit COGS totaled US$ 19,225/t, down by 7% y/y and 5% q/q, in line with lower costs for own-sourced and external feed.

Prior periods were restated. (b) Adjusted EBITDA EBITDA defines profit or loss before interest, tax, depreciation, depletion and amortization. The definition of Adjusted EBITDA for the Company is the operating income or loss plus EBITDA associates and joint ventures, and excluding the amounts charged as (i) depreciation, depletion and amortization and (ii) impairment and gains (losses) on disposal of non-current assets. However, our adjusted EBITDA is not the measure defined as EBITDA under IFRS and may possibly not be comparable with indicators with the same name reported by other companies. Adjusted EBITDA should not be considered as a substitute for operational profit or as a better measure of liquidity than operational cash flow, which are calculated in accordance with IFRS. Vale provides its adjusted EBITDA to give additional information about its capacity to pay debt, carry out investments and cover working capital needs. The following tables shows the reconciliation between adjusted EBITDA and operational cash flow and adjusted EBITDA and net income, in accordance with its statement of changes in financial position. The definition of Adjusted EBIT is Adjusted EBITDA plus depreciation, depletion and amortization.
