Iron ore, copper and nickel sales increased by 5% (+4 Mt), 20% (+15 kt) and 6% (+2 kt) y/y, respectively, supported by solid operational performance. • The average realized iron ore fines price was US$ 94.4/t, 11% higher q/q and 4% higher y/y, outperforming the broader increase in iron ore reference price. This performance reflects quality premiums improvements driven by the product portfolio strategy. • All-in costs for iron ore declined 4% y/y to US$ 52.9/t, driven by enhanced quality premiums and reduced freight costs. • Iron ore fines’ C1 cash cost, excluding third-party purchases, remained largely flat y/y and on track to meet the 2025 guidance, reaching US$ 20.7/t in the quarter. • Copper all-in costs were down 65% y/y (to US$ 994/t), while nickel all-in costs declined 32% y/y (to US$ 12,347/t). These improvements were driven by operational efficiencies, increased production and higher by-products revenues. • Copper all-in cost guidance for 2025 further revised down to US$ 1,000-1,500/t (from US$ 1,500-2,000/t), driven by higher gold prices. Nickel all-in cost guidance for 2025 revised down to US$ 13,000-14,000/t, (from US$ 14,000-15,500/t), driven by solid operational performance and strong metals price, benefitting polymetallic assets. • Proforma EBITDA totaled US$ 4.4 billion, up 17% y/y and 28% q/q, driven by higher volumes, cost efficiencies, and higher iron ore, copper and by-products prices. • Capital expenditures of US$ 1.3 billion were US$ 0.1 billion lower y/y, on track to meet the guidance of US$ 5.4-5.7 billion set for 2025. • Recurring Free Cash Flow generation was US$ 1.6 billion, US$ 1.0 billion higher y/y, primarily reflecting stronger EBITDA. • Expanded net debt of US$ 16.6 billion at quarter-end, US$ 0.8 billion lower q/q, driven by robust FCF generation. Rio de Janeiro, October 30th, 2025 Vale’s performance in 3Q25 “We delivered another strong quarter, marked by solid operational performance, continued progress on our strategic agenda and commitment to safety. Iron ore production reached its highest quarterly level since 2018 and copper had its best Q3 result since 2019, while we continued to improve our cost competitiveness on nickel. All of these reflect the operational consistency and relentless dedication of our teams. We advanced key growth projects under the New Carajás program and successfully started up the 2nd furnace at Onça Puma, unlocking growth and reinforcing our long-term value creation strategy. Our flexible iron ore portfolio, supported by an extended value chain, once again proved essential in enhancing our competitiveness and resilience across market cycles. Safety remains our priority, and we are very happy to have achieved an important milestone by having no dams classified at emergency level 3 - a fundamental step in our journey to become a trusted partner to society. These results strengthen my confidence in Vale’s future and in the value we are creating for all stakeholders.", commented Gustavo Pimenta, CEO – 2 – Business Highlights Iron Ore Solutions • Successful execution of the portfolio strategy, with a US$ 2/t improvement in iron ore fines premiums q/q, supported by the increase in blended and concentrated products. In the quarter, Vale also officially launched its mid-grade Carajás product, which provides greater operational flexibility and optimization of the mining plan. The company remains focused on maximizing value through an optimized product portfolio enabled by its supply chain flexibility. Energy Transition Metals • Onça Puma 2nd furnace successfully started operations in September. Delivered on schedule and 13% below budget (US$ 480 million final CAPEX), the project adds 15 ktpy of nickel capacity, increasing the site's nameplate capacity to 40 ktpy. Recent developments • New Carajás Program continues to advance with (i) the operating license obtained for mine-related activities at the Serra Sul +20 Mtpy iron ore project, (ii) the operating license obtained for the Serra Leste expansion to 10 Mtpy of iron ore production, and (iii) progress on access works for the Bacaba copper project, which obtained its preliminary license in June and is awaiting installation license. • Aliança Energia JV was completed in September after regulatory approvals. Following the completion, Vale received US$ 1 billion in proceeds and now holds a 30% stake in the JV, with GIP holding 70%. The transaction ensures Vale's continued access to renewable power at competitive costs, supporting its 100% renewable energy matrix in Brazil. • Vale launched an optional offer to acquire up to all participative debentures in October. The initiative aims to optimize the company’s capital structure and reinforce its capital allocation strategy through proactive liability management. ESG Tailing Dams • Forquilha III dam had its emergency level reduced from 3 to 2, following the approval by the Brazilian National Mining Agency (ANM). With this milestone, Vale no longer has any dams classified at emergency level 3. The structure, part of the Upstream Dam Decharacterization Program, will begin decharacterization works in 2026. • Doutor and Dicão Leste dams had their emergency levels removed, following the approval by ANM. Both structures received a positive Declaration of Stability Condition (DCE), confirming their structural safety. Since 2022, 21 dams have been removed from emergency level status. • Grupo dam, at the Fábrica mine in Minas Gerais, was fully eliminated, marking 60% completion of the Upstream Dam Decharacterization Program, with 18 structures eliminated since 2019. • Vale successfully implemented the Global Industry Standard on Tailings Management (GISTM) at all tailings dams, as part of its ongoing commitment to the ICMM and its stakeholders. This significant achievement underscores the company’s dedication to safeguarding people and communities, reflecting its disciplined approach to applying the best dam management practices. Reparation Brumadinho • The execution of the Brumadinho Integral Reparation Agreement continues to progress, with approximately 79% of the agreed-upon commitments completed by 3Q25 and in accordance with the deadlines outlined in the settlement. Mariana • The Samarco reparation program continues to advance, with R$ 70 billion disbursed as of September 30, 2025. Progress under the definitive compensation program (PID) remains strong, with over 327 thousand individuals formally enrolled and more than 291 thousand agreements signed until mid-October, showing steady advancement in resolving the underlying claims.

Recurring Free Cash Flow generation reached US$ 1.6 billion in 3Q25, US$ 1.0 billion higher y/y, mainly as a result of stronger EBITDA performance and lower impact from negative working capital. Additionally, results benefited from the settlement of derivatives under the currency hedge program, which contributed to a reduction in net financial expenses. The negative working capital in the quarter was driven by longer lead times of inventories as well as higher accrued prices and volumes at quarter-end. Free Cash Flow generation reached US$ 2.6 billion, positively impacted by US$ 1.0 billion in proceeds received from the completion of the Aliança Energia transaction, in addition to the US$ 1.6 billion in Recurring Free Cash Flow. Vale’s cash position was mainly impacted by US$ 1.5 billion in interest on capital paid in September and a net disbursement of US$ 0.7 billion as part of liability management. These combined effects resulted in a US$ 0.4 billion increase in cash and cash equivalents during the quarter. Free Cash Flow 3Q25 - US$ million ¹Includes income taxes and REFIS (US$ -558 million), interests on loans and borrowings (US$ -185 million), leasing (US$ -42 million), net cash received on settlement of derivatives (US$ 93 million), and other financial revenues (US$ 39 million). ² Related to Associates and Joint Ventures EBITDA that was included in the Proforma EBITDA, net of dividends received. ³ Includes incurred expenses on Brumadinho (US$ -73 million) and payments on dam decharacterization (US$ -110 million). ⁴ Includes disbursements related to railway concession contracts (US$ -154 million), and others. ⁵ Payments related to Brumadinho and Samarco.

The stability in costs reflects a lower impact from the inventory turnover, when compared to the same quarter of last year, which was mainly offset by increased maintenance and material costs related to mine and port activities aimed at improving asset reliability and future operational performance. Vale remains highly confident in achieving its 2025 C1 cash cost, excluding third-party purchases, guidance (US$ 20.5−22.0/t). C1 cash cost, excluding third-party purchase costs - US$/t, 3Q25 vs. 3Q24 1 Including demurrage (US$ 0.2/t) and others (US$ 0.1/t). Vale's average maritime freight cost was US$ 18.8/t, US$ 4.6/t below the Brazil-China C3 route benchmark in the period, reflecting the effectiveness of the company’s long-term affreightment strategy, which reduces both costs and volatility. Freight costs increased sequentially by US$ 0.5/t, mainly due to greater exposure to spot freight rates, a seasonal effect as a result of the usual higher sales in the second semester. CFR sales totaled 67.3 Mt in Q3, representing 90% of total iron ore fines sales.

The average realized iron ore pellets price was US$ 130.8/t, US$ 3.3/t lower q/q, mainly impacted by lower quarterly pellet premiums, partially offset by higher iron ore reference prices in the quarter. Pellets’ cash costs per ton were 5% higher y/y, totaling US$ 77.2/t, primarily due to the deconsolidation of the Vale Oman Distribution Center (VODC) following the sale of a 50% stake, combined with unfavorable FX effects.

The result was driven by internal improvements, including sustained sales volume growth and cost efficiencies. Those effects, combined with favorable market conditions, particularly for copper and gold, contributed to a strong quarter for Vale Base Metals. Copper EBITDA increased by 71% y/y, totaling US$ 614 million, driven by favorable market prices, with gold (US$ 117 million) and copper LME (US$ 55 million) positively impacting performance, and increased sales volumes (US$ 79 million). Nickel EBITDA increased by US$ 180 million y/y, totaling US$ 114 million, turning around last year’s negative performance. The increase was mostly explained by improved feed availability from Voisey's Bay at lower costs (US$ 91 million), increased nickel and by-products sales volumes (US$ 62 million), and a decrease in external feed costs (US$ 17 million). EBITDA variation – US$ million (3Q25 vs. 3Q24) ¹ Includes variations of (i) US$ 184 million in realized prices for by-products, (ii) US$ 13 million in PPA and (iii) US$ -11 million in realized prices for copper and nickel. ² Includes a variation of US$ 128 million in by-products volumes. ³ Includes variations of (i) US$ 91 million in Voisey's Bay, (ii) US$ -42 million in polymetallic assets, (iii) US$ 17 million in lower cost of external feed due to lower volumes and the impact of LME prices in Refineries operation and (iv) US$ -14 million in Salobo and Sossego.

Revenues Net revenues totaled US$ 1.086 billion, 43% higher y/y, driven by higher realized copper prices (US$ 55 million) and volumes (US$ 80 million), as well as higher by-products revenues. The higher by-product revenue is explained by higher gold prices (US$ 117 million) and the increase in gold volumes sold in copper concentrates (US$ 49 million). The average realized copper price was US$ 9,818/t, 9% higher q/q, in line with higher LME prices and lower TC/RC discounts, offsetting timing effects. Average realized copper price 3Q25 – US$/t Note: Vale’s copper products are sold on a provisional pricing basis, with final prices determined in a future period.

All-in costs were US$ 994/t, 65% lower y/y, primarily driven by higher by-product revenues and lower TC/RCs and other discounts. These positive effects were partially offset by higher unit COGS and increased expenses. Guidance for 2025 was revised down to US$ 1,000-1,500/t (from US$ 1,500-2,000/t). Unit COGS was US$ 6,221/t, up 4% y/y, due to higher mineral tax payments. The increase was driven by changes to the TFRM rate introduced in March 2025. TFRM is a Brazilian tax on the supervision of exploration and mining activities, and the rate adjustment led to a unit cost increase of US$ 195/t. This effect was partially offset by fixed cost dilution as a result of higher production volumes. Unit COGS, net of by-products, totaled US$ 515/t, declining by 77% y/y, explained by gold revenues at both Salobo and Sossego, following higher gold prices and the increase in gold volumes sold in copper concentrates.

Revenues Net revenues totaled US$ 1,010 billion, increasing by 12% y/y, driven by stronger by-product prices (US$ 65 million) and sales volumes (US$ 47 million). The average realized nickel price was US$ 15,445/t, down 2% q/q, explained by a 1% decrease in LME prices and the negative impact of timing effects. The average realized nickel price was 3% higher than the LME average, mainly due to the 72% share of Upper-Class I products in the North Atlantic mix, resulting in an overall positive impact of premiums of US$ 444/t.

All-in cost totaled US$ 12,347/t, decreasing by 32% y/y and in line q/q. The reduction was driven by lower unit COGS and increased by-product revenues. Guidance for 2025 was revised down to US$ 13,000-14,000/t (from US$ 14,000-15,500/t). Unit COGS, excluding external feed purchases, was US$ 22,835/t, declining by 19% y/y, primarily due to fixed cost dilution at lower costs in Voisey's Bay. Unit COGS totaled US$ 20,310/t, down by 12% y/y and 2% q/q, primarily due to lower costs for own sourced 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.
