Safety remains a core value, and we’re encouraged by the clear progress toward an accident-free work environment across our operations. As we advance in our strategy to strengthen our flexible product portfolio, we continue to lower costs and build resilience, which will help us navigate well in any market scenario. This quarter, we also reached a key milestone as our first copper mine project under the New Carajás program obtained its preliminary license, marking tangible progress toward future growth. These achievements reaffirm our strategy and demonstrate our commitment to building a leading mining platform that creates long-term value for all stakeholders.", commented Gustavo Pimenta, Chief Executive Officer. Results Highlights • Operational and cost performance improved across all business segments; all guidances on track. Copper and nickel sales increased 17% (12.9 kt) and 21% (7.0 kt) y/y, respectively. Iron ore shipments declined 3% (2.4 Mt) y/y, reflecting the ongoing portfolio optimization strategy. • The average realized iron ore fines price was US$ 85.1/t, 6% lower q/q and 13% lower y/y, in line with the broader decline in iron ore reference prices. • Iron ore fines’ C1 cash cost, excluding third-party purchases, decreased by 11% y/y, reaching US$ 22.2/t, marking the fourth consecutive quarter of year-over-year cost reduction. • All-in costs were down 10% in iron ore (US$ 55.3/t), 60% in copper (US$ 1,450/t), and 30% in nickel (US$ 12,396/t) y/y, as a result of the implementation of efficiency initiatives and higher production. • Copper all-in cost guidance for 2025 revised down to US$ 1,500-2,000/t (from US$ 2,800-3,300/t), driven by solid operational performance and higher-than-expected gold prices. • Proforma EBITDA totaled US$ 3.4 billion, 7% higher q/q and 14% lower y/y. The strong performance of copper and nickel segments, along with lower C1 cash cost in iron ore, partly offset the impact of weaker commodity prices. • Capital expenditures of US$ 1.1 billion were US$ 0.2 billion lower y/y, on track to meet the 2025 guidance of US$ 5.9 billion and reflecting ongoing efficiency initiatives. • Recurring free cash flow generation was US$ 1.0 billion, US$ 0.8 billion higher y/y, as a result of more favorable working capital variation and lower capital expenditures. • Expanded net debt of US$ 17.4 billion as of June 30th was US$ 0.8 billion lower q/q, mainly driven by free cash flow generation. • Approval of US$ 1.448 billion in interest on capital to be paid in September 2025, implying an annualized yield of 7%1. 1 Considering the market cap as of June 30th, 2025. Rio de Janeiro, July 31st, 2025 Vale’s performance in 2Q25 – 2 – Business Highlights Iron Ore Solutions • The first shipment of the Capanema project was completed in Q2. The project will add 15 Mtpy of net iron ore capacity, with ramp-up completion expected in the first half of 2026. This expansion will support the company’s production guidance for 2025 (325-335 Mt). Energy Transition Metals • Vale Base Metals obtained the Preliminary License for the Bacaba project in June. The project is designed to extend the life of the Sossego Mining Complex, contributing with an average annual copper production of around 50 ktpy over an 8-year mine life. Approximately US$ 290 million will be invested during the project’s implementation phase, and the production start-up is planned for the 1H28. • Commissioning of the Onça Puma's 2nd furnace project began in July. Supported by a planned investment of US$ 555 million, the project is expected to contribute to cost reduction across the complex and increase nickel production capacity by 12–15 ktpy. With 94% of physical progress completed, initial metal production is anticipated in 4Q25. ESG Tailing Dams • The Grupo dam was removed from emergency level in May, following a stability declaration. In July, the Xingu dam’s emergency level was lowered from 2 to 1 after improved monitoring and structural evaluations. Grupo dam is expected to be fully decharacterized by late 2025, and Xingu dam by 2034. Vale's ongoing Decharacterization Program has decharacterized 17 of 30 upstream dams since 2019. Circular Mining • Vale's Waste-to-Value program continues to advance, transforming waste and tailings into valuable resources. The program currently encompasses 150 initiatives, including the tailings reprocessing operation in Gelado and Vargem Grande dams and the WH wastepile in Capanema. In the 1H25, Vale produced around 9 Mt from circularity sources, 14% higher than the same period in 2024. Forest protection • Vale has achieved 200,000 hectares of forest conserved, representing 50% of its 2030 voluntary target. The company currently supports forest protection efforts across 1 million hectares worldwide, including 800,000 hectares in the Amazon in collaboration with ICMBio. Transparency • Vale published its sustainability-related financial disclosures report, available here, marking a significant step in alignment with international ISSB standards and Brazilian CBPS Sustainability Disclosure Pronouncements. The voluntary disclosure anticipates regulatory requirements under CVM Resolution 193/23 by two years, underscoring Vale’s commitment to transparency and the continued evolution of its climate and sustainability reporting practices. Reparation Brumadinho • The Brumadinho Integral Reparation Agreement continues to progress, with approximately 77% of the agreed-upon commitments completed by 2Q25 and in accordance with the deadlines outlined in the settlement. In addition, R$ 3.9 billion has been paid in individual compensation since 2019. Mariana • The Samarco reparation program continues to progress, with R$ 60 billion disbursed as of June 30, 2025. The definitive compensation program (PID) exceeded initial expectations with formal adherence from over 290,000 individuals. This strong level of engagement reflects the success of the agreement and highlights the effectiveness in resolving the underlying claims through a transparent and structured process.

Financial Results – 4 – EBITDA Proforma EBITDA was US$ 3.4 billion in 2Q25, 14% lower y/y, mainly as a result of 13% lower iron ore reference prices. This effect was partly offset by (i) continued progress on cost and expenses efficiency initiatives, which drove improved performance in both Energy Transition Metals and Iron Ore segments, and (ii) the positive effect of the BRL depreciation. Proforma EBITDA 2Q25 vs. 2Q24 - US$ million 1 Excluding Brumadinho expenses. 2Q24 Proforma EBITDA was restated excluding one-off events (US$ 5 million). 2 Including volume, EBITDA from associates and JV’s and others. Net Income Proforma net income was US$ 2.1 billion in 2Q25, 6% higher y/y, positively impacted by the mark-to-market valuation of swaps, which benefited from favorable currency variation movements over the quarter, contributing to the US$ 1.4 billion y/y increase in financial results. This was partly offset by lower Proforma EBITDA and the negative effect from Associates & JV's, mostly related to the Samarco provision adjustment. Net income attributable to Vale’s shareholders was US$ 2.1 billion, 24% lower y/y, since no non-recurring items were reported for 2Q25. Proforma net income 2Q25 vs. 2Q24 – US$ million 1 Excluding US$ 282 million in taxes related to non-recurring items. 2 Including variations of (i) US$ -180 million in equity results and (ii) US$ -49 million in EBITDA from associates and JV’s. 3 Excluding US$ 1.06 billion related to gains on divestment of PTVI in 2Q24. ⁴ Including a variation of US$ 1.01 billion in currency and interest rate swaps. 5 Including variations of (i) US$ -38 million in Brumadinho and decharacterization of dams, (ii) US$ -18 million in Net income attributable to noncontrolling interests and (iii) US$ 13 million in depreciation, depletion & amortization. Proforma EBITDA – 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 4 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 the table on page 3.

Recurring Free Cash Flow generation reached US$ 1.0 billion in 2Q25, US$ 0.8 billion higher y/y, mainly explained by lower working capital variation and lower capital expenditures. In the quarter, the neutral working capital was primarily attributable to accrued sales at the quarter's end and longer sales lead times, which resulted in higher receivables and higher inventory levels, respectively. These effects were largely offset by an increase in accounts payables, driven by the extension of supplier payment terms. Vale’s cash position was further positively impacted by ongoing liability management initiatives, resulting in a US$ 1.5 billion increase in cash and cash equivalents during the quarter. Free Cash Flow 2Q25 - US$ million ¹Includes income taxes and REFIS (US$ -468 million), interests on loans and borrowings (US$ -269 million), leasing (US$ -33 million), net cash received on settlement of derivatives (US$ 149 million), and other financial revenues (US$ 40 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$ -84 million) and payments on dam decharacterization (US$ -83 million). ⁴ Includes disbursements related to railway concession contracts (US$ -105 million), streaming transactions adjustments to market price (US$ -168 million), and others. ⁵ Payments related to Brumadinho and Samarco.

Expanded net debt reduced by US$ 0.8 billion q/q, totaling US$ 17.4 billion, with the higher free cash flow generation q/q positively impacting our cash position. Vale's expanded net debt target remains at US$ 10-20 billion. Gross debt and leases reached US$ 17.8 billion as of June 30th, 2025, US$ 1.6 billion higher q/q, mainly as a result of the issuance of debentures (approximately US$ 1.1 billion) and funds raised with banks (US$ 0.6 billion). An increase in the Samarco provision was recognized in 2Q25 in the amount of US$ 195 million, in most part due to a revision of the costs to complete the initiatives for the definitive compensation program (PID). The average debt maturity decreased to 9.1 years at the end of 2Q25 from 9.5 years at the end of 1Q25.

Iron Ore Fines EBITDA decreased by 22% y/y, totaling US$ 2.396 billion, mostly explained by lower realized prices (US$ -901 million). This effect was partially offset by (i) lower costs and expenses (US$ 106 million), mainly due to lower C1 cash costs, (ii) the positive effect of the BRL depreciation (US$ 99 million), and (iii) lower freight costs (US$ 44 million). Iron Ore Pellets EBITDA decreased by 34% y/y, totaling US$ 477 million, mostly explained by lower realized prices (US$ -172 million) and lower volumes (US$ -113 million).

This is the fourth consecutive quarter of year-over-year cost reduction. The reduction was mainly driven by: (i) higher production from sites with lower production costs (e.g., Northern System), supporting fixed cost dilution and mix effect, (ii) lower demurrage costs, which reached the lowest level for a Q2 since 2020, driven by efficiency initiatives such as fleet speed management and optimization of queues and chartering processes, (iii) a positive inventory turnover effect, with the consumption of lower-cost inventories from previous quarters, and (iv) the positive impact of the BRL depreciation.

Unit COGS was US$ 6,057/t, down by 10% y/y, due to higher fixed cost dilution at Salobo and Sossego following the full ramp-up of the Salobo complex and increased copper feed grade and plant availability at Sossego. Unit COGS, net of by-products, totaled US$ 1,095/t, declining by 64% y/y, mainly reflecting the positive impact of by-product revenues at both Salobo and Sossego, following higher gold prices.

Revenues Net revenues totaled US$ 1.012 billion, increasing by 15% y/y, driven by stronger nickel and by-product sales volumes. The average realized nickel price was US$ 15,800/t, down 2% q/q, explained by a 3% decrease in LME prices. In 2Q25, the average realized nickel price was 4% higher than the LME average, mainly due to the 75% share of Upper-Class I products in the mix of North Atlantic, with an overall positive impact of premiums of US$ 414/t.

All-in costs, PTVI-adjusted, totaled US$ 12,396/t, decreasing by 30% y/y and 21% q/q. The reduction was driven by lower unit COGS and higher copper sales. Unit COGS, excluding external feed purchases, PTVI-adjusted was US$ 22,194/t, declining by 29% y/y and 21% q/q, primarily due to fixed cost dilution from the ramp-up of Voisey's Bay underground mines. In Sudbury, higher production and reduced planned refinery maintenance were also supportive to the y/y improvement. Unit COGS totaled US$ 20,743/t, down by 3% y/y and 11% q/q, in line with lower costs for own sourced and external feed. Unit by-product revenues were US$ 8,510/t, 20% higher y/y, mainly driven by sales volume.

(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.
