Rio de Janeiro, October 29th, 2026 3Q26 Quarterly Results “Our third-quarter results reflect disciplined execution of our strategy and a continued focus on operational excellence. In a dynamic market environment, our portfolio flexibility, affreightment strategy, and hedging program helped protect margins and support solid cash flow generation, further strengthening our balance sheet. In iron ore, we are building a more flexible and competitive operating platform. The start-up of the Serra Sul +20 project, together with the commissioning of the Compact Crushing project, will further enhance S11D's performance and reinforce its position as a world-class asset. Combined with solid performance across our asset base, these initiatives positions us well to finish the year strongly. Vale Base Metals continues to gain momentum, with Salobo delivering record third-quarter production and both copper and nickel on track to reach the upper half of the production guidances. With the approval of the Salobo CPF project, we take another important step in our copper growth journey, leveraging our existing assets and infrastructure to grow with capital efficiency. Together, these achievements strengthen Vale's resilience and position us to create sustainable value over the long term.", commented Gustavo Pimenta, CEO Selected financial indicators US$ million 3Q26 3Q25 Δ y/y 2Q26 Δ q/q 9M26 Net operating revenues Adjusted EBITDA Proforma EBITDA1 Free cash flow Recurring free cash flow Attributable net income Attributable proforma net income Net debt2 Expanded net debt 10,599 3,327 3,508 2,230 1,373 10,420 4,369 4,399 2,453 2% 10,498 -24% -20% 3,676 4,066 -9% 1,562 1,255 1,255 13,097 2,685 2,744 12,452 -12% -53% -54% 1,505 1,505 1,375 1,566 5% 13,173 16,413 Capital expenditures 1,250 16,640 1,250 1 Excluding expenses related to Brumadinho and non-recurring items. 2 Including leases (IFRS 16).

Iron ore sales increased by 0.3% (0.3 Mt) y/y, despite a 6% (6 Mt) decline in production over the same period. Copper sales declined 4%, as expected, reflecting the planned Sossego SAG mill rebuild. Nickel sales increased 16.1% (6.9 kt) y/ y, supported by stronger production. All 2026 production guidances reaffirmed, with copper and nickel pointing to the upper half of the ranges. • Iron ore price realization reflecting external factors. The average realized iron ore fines price was US$ 85.1/t, down 10% q/q and y/y, due to lower reference prices and temporary adjustments related to CFR sales. • Higher realized copper price realization. Realized copper prices increased to US$ 15.314/t (+9% q/q, +56% y/y), above the LME price variation. Realized nickel prices reached US$ 16,898/t (-6% q/q, +9% y/y), with higher premiums partly offsetting lower reference prices. • Iron ore costs impacted by BRL and oil prices. C1 cash cost was US$ 23.1/t (+12% y/y), mainly reflecting the BRL appreciation and diesel costs, while all-in costs reached US$ 60.4/t (+21% y/y), further pressured by higher freight costs. • Copper costs continue to improve. Copper all-in costs at US$ -175/t (US$ -1.2k/t y/y), supported by strong by-product revenues. Nickel all-in costs increased in line with expectations, up 18% y/y to US$ 14,552/t, reflecting higher planned maintenance. • Proforma EBITDA of US$ 3.5 billion, down 20% y/y (-14% q/q), mainly driven by the decrease in iron ore fines realized prices and external cost pressures, including the BRL appreciation and higher bunker prices. • Capital expenditures of US$ 1.3 billion, flat y/y, with full-year investments expected to be at the lower end of the US$ 5.4-5.7 billion guidance range. • Recurring Free Cash Flow of US$ 1.4 billion, US$ 0.2 billion lower y/y, as successful hedging and working capital management partly offset lower Proforma EBITDA. Total Free Cash Flow reached US$ 2.2 billion. • Expanded net debt of US$ 16.4 billion, US$ 0.2 billion lower q/q, driven by cash flow generation.-1- Iron Ore Solutions Business Highlights • Iron ore production totaled 88.4 Mt (-6% y/y), mainly reflecting lower run-of-mine availability at Serra Norte. A new quarterly record at Serra Sul and incremental volumes from the Capanema and VGR1 projects partly offset the decline, demonstrating the successful ramp-up of key growth projects. Pellet production totaled 8.6 Mt (+7% y/y). • Based on year-to-date performance and expected operational improvements, Vale remains confident in delivering the lower end of its iron ore production guidance (335-345 Mt) and the midpoint of its pellet production guidance (30-34 Mt) for 2026. • The Compact Crushing project started operation in Q3. Together with the ramp-up of the Serra Sul +20 project, it is expected to enhance operational flexibility and support performance from 2027. • The operations at Fábrica mine resumed in September, following compliance with applicable safety, environmental, and licensing requirements, as well as actions established under the Commitment Agreement. Vale Base Metals • Copper production totaled 85.5 kt (-6% y/y), reflecting the planned SAG mill rebuild at Sossego, partly offset by strong performance at Salobo. Nickel output totaled 49.7 kt (6% y/y), driven mainly by the strong performance at Onça Puma's second furnace and the highest quarterly output at the Sudbury Refinery since 4Q13. • Vale is on track to achieve the upper half of its 2026 production guidance ranges for both copper (360-380 kt) and nickel (185-200 kt). Year-to-date, copper and nickel production increased by 4% and 8% y/y, respectively. • The Salobo Coarse Particle Flotation (CPF) project advanced to execution in August. Expected to add up to ~30 ktpy, the project supports VBM's ambition to reach 420-500 ktpy of copper production by 2030. Physical progress reached 17%, with start-up expected in 1H28, about one year ahead of schedule. • The Thompson Mine Complex transaction was completed in October, concluding the strategic review process and establishing Exiro Nickel as the new owner and operator, while VBM retained an 18.9% interest and a multi-year nickel concentrate offtake agreement. Other developments • As part of Vale's ongoing risk management strategy, the Brent oil hedge program, combined with forward freight agreements (FFAs) execution, generated an economic gain of US$ 97 million in the quarter, equivalent to approximately US$ 1.4/dmt of iron ore sold. Recognized in the financial results, this benefit offsets part of the higher oil prices that pressured all-in costs in the quarter. Including the Brent oil hedge effect, iron ore all-in costs would be equivalent to US$ 59/dmt in the quarter. • The B7A dam in Nova Lima (MG) had its emergency level status lifted, following Brazilian National Mining Agency approval. The decision comes after the completion of the works to decharacterize the structure. Since 2020, 29 dams have been removed from emergency level status, representing an 83% reduction. Reparation Brumadinho • The execution of the Brumadinho Integral Reparation Agreement continues to progress, with approximately 84% of the agreed-upon commitments completed by 3Q26 and in accordance with the deadlines outlined in the settlement. The "To Pay" obligations of the Reparation Agreement were completed in October, 2026. Mariana • The Samarco reparation program continues to advance, with R$ 83.8 billion disbursed as of September 30, 2026. As of October 20th, 2026, more than 649 thousand individuals were compensated, including more than 322 thousand under the Definitive Indemnification Program (PID). In August, 19 additional municipalities joined the agreement, bringing the total number of signatories to 45 of the 49 eligible municipalities, including Mariana.-2- Operational Results Production Summary 000’ metric tons 3Q26 3Q25 ∆ y/y 2Q26 ∆ q/q 9M26 9M25 Δ y/y 2026 guidance Iron ore¹ Pellets Copper Nickel 88,354 8,554 94,403 -6% 84,255 5% 242,284 245,671 7,997 85.5 49.7 1 90.8 46.8 7% -6% 6% 7,303 98.4 42.0 17% 24,026 -13% 18% 286.2 141.0 23,031 274.3 131.0 Including third-party purchases, run-of-mine and feed for pelletizing plants. 2 Iron ore agglomerates guidance, including iron ore pellets and briquettes.

In Q3, the Compact Crushing project started operations. Together with the Production Pelletizing mass loss Moisture change and adjustments Concentration mass loss (ex-Brazil) Inventory consumption Sales Serra Sul +20 project ramp-up, it is expected to further enhance operational flexibility and support production performance from 2027 onward. • Southeastern System: production was broadly stable y/y, totaling 22.7 Mt in the quarter. The result was supported by higher output from the Mariana Complex, reflecting improved performance at Alegria and Fazendão, as well as the continued ramp-up of Capanema, which offset planned maintenance activities in Brucutu and Itabira. • Southern System: production decreased by 0.7 Mt y/y, totaling 13.1 Mt in the quarter, mainly reflecting the stoppage of Fábrica and Viga operations since January 2026. This impact was partly offset by higher output at the Vargem Grande Complex, supported by the VGR1 plant. Operations at Fábrica resumed in September. • Pellets: production increased by 0.6 Mt y/y, totaling 8.6 Mt in the quarter, mainly driven by higher pellet feed availability from Brucutu and Itabira, as well as increased production at Vargem Grande pellet plant. • Iron ore sales totaled 86.3 Mt, 0.3 Mt higher y/y, mainly reflecting the sale of inventories built in previous periods.-3- Operational Results Copper operations • Salobo: copper production increased by 4.6 kt y/y, reaching 57.6 kt in the quarter, driven by strong mine and mill performance, resulting in its highest production for Q3. Copper production, kt (3Q26 vs. 3Q25) 90.8 (4.6) (0.7) 85.5 • Sossego: copper production decreased by 9.2 kt y/y, reaching 10.1 kt in the quarter, reflecting the ongoing planned SAG mill rebuild. The rebuild commenced in August and is expected to be completed in the second half of November. During this period, the Sossego plant continues to operate using a mobile crushing system, partly mitigating the impact of the SAG mill shutdown. 3Q25 Brazil Canada 3Q26 • Canada: copper production decreased by 0.7 kt y/y, reaching 17.7 kt in the quarter, reflecting the impact of preventive SAG mill maintenance at Voisey’s Bay brought forward to July. Ontario production remained solid, supported by additional throughput from the Clarabelle Mill expansion and the commissioning of Rod Mill #2, which started operations in September. • Payable copper sales1 totaled 86.3 kt, 3.7 kt lower y/y, mainly reflecting the production decrease. Nickel operations • Sudbury: own sourced finished nickel production increased by 2.8 kt y/y, reaching 11.3 kt in the quarter, supported by higher own sourced feed availability, solid mine performance, and the successful ramp-up of processing facilities following planned maintenance in Q2. As a result, production at Sudbury Refinery reached its highest quarterly level since 4Q13. Nickel production, kt (3Q26 vs. 3Q25) 1.0 46.8 3Q25 2.8 49.7 (0.9) Brazil Canada External feed 3Q26 • Voisey’s Bay: own sourced finished nickel production decreased by 1.1 kt y/y, reaching 9.6 kt in the quarter, as a result of Long Harbour annual maintenance, which was brought forward to September. • Thompson: own sourced finished nickel production decreased by 0.7 kt y/y, reaching 2.2 kt in the quarter, with the higher consumption of own sourced feed in Sudbury. • Onça Puma: finished nickel production increased by 2.8 kt y/y, reaching 8.7 kt in the quarter, reflecting the strong performance of the second furnace, resulting in Onça Puma’s highest Q3 production. • Nickel sales totaled 49.8 kt, 6.9 kt higher y/y, in line with production. 1 Sales volumes are lower than production volumes due to payable copper vs. contained copper: part of the copper contained in the concentrates is lost in the smelting and refining process, hence payable quantities of copper are approximately 3.5% lower than contained volumes.-4- Financial Results US$ million 3Q26 3Q25 Δ y/y 2Q26 Δ q/q 9M26 9M25 Δ y/y Proforma EBITDA Net operating revenues 10,599 10,420 2% 10,498 1% 30,355 27,343 11% COGS (7,940) (6,632) 20% (7,294) 9% (21,407) (18,168) 18% SG&A (159) (158) 1% (176) -10% (487) (434) 12% Research and development (189) (151) 25% (185) 2% (505) (433) 17% Pre-operating and stoppage expenses (86) (50) 72% (100) -14% (235) (211) 11% Brumadinho & decharacterization of dams¹ (181) (30) 503% (101) 79% (347) (165) 110% Non-recurring expenses — — n.a.

Recurring Free Cash Flow totaled US$ 1.4 billion, US$ 189 million lower y/y, mainly due to lower Proforma EBITDA generation. This effect was largely offset by (i) a working capital release in the quarter, (ii) lower taxes paid, and (iii) positive results from the cash settlement of derivatives, which contributed US$ 249 million in cash in the quarter and US$ 702 million year-to-date. The working capital release in the quarter was mainly driven by (i) an increase in accounts payable, due to extended supplier payment terms, and (ii) inventory drawdown, with higher sales in Q3. These effects were partly offset by an increase in accounts receivable, reflecting higher sales volumes toward the end of the quarter. Vale Base Metals continued to positively contribute to cash generation, delivering Free Cash Flow of US$ 484 million in the quarter and US$ 1.1 billion year-to-date. Free Cash Flow totaled US$ 2.2 billion, US$ 223 million lower y/y, supported by a non-recurring cash release related to tax incentives. Vale’s cash position was impacted by US$ 1.7 billion in dividend and interest on capital payments during the quarter, along with continued liability management, resulting in a US$ 735 million decrease in cash and cash equivalents.

Iron Ore Fines EBITDA was US$ 2.1 billion, 39% lower y/y, reflecting (i) lower realized prices (US$ -705 million), (ii) exogenous effects, such as higher freight costs (US$ -273 million) due to higher bunker fuel prices and the negative impact of the BRL appreciation (US$ -66 million), and (iii) higher costs and expenses (US$ -322 million). These effects were partly offset by higher sales volumes (US$ 23 million). Iron Ore Pellets EBITDA increased by 1% y/y, totaling US$ 516 million, mainly driven by higher realized prices (US$ 40 million) as a result of higher pellet premiums.

Revenues The average realized iron ore fines price was US$ 85.1/t, US$ 9.9/t lower q/q, mainly reflecting the negative impact of lower reference prices (US$ 8.3/t lower q/q) and more negative FOB sales adjustments (US$ 1.9/t lower q/q). The latter was primarily driven by higher spot freight rates at the end of the quarter, which resulted in a larger negative cut-off adjustment for CFR sales still in transit at quarter-end. Assuming lower freight rates at the end of 4Q26, the quarter on-quarter change in this adjustment is expected to positively impact realized prices. These negative effects were partly offset by the positive contribution from pricing mechanisms (US$ 0.7/t higher q/q).

The contribution from iron ore fines quality premiums decreased (US$ 1.4/t lower q/q), mainly reflecting a lower premium contribution from Mid-grade Carajás products due to the operational restrictions at Serra Norte. Market premiums for low-alumina products remained strong, supporting a solid price realization. Lower overall iron ore fines realized premiums were fully offset by a higher contribution from the Pellets business (US$ 1.4/t higher q/q), driven by stronger quarterly pellet premiums and a greater share of direct reduction pellet sales.

The increase mainly reflects (i) the negative impact of the BRL appreciation, (ii) an unfavorable production mix effect from the lower contribution of Serra Norte volumes, which have structurally lower production costs, (iii) higher diesel prices in the Brazilian domestic market, and (iv) costs related to the deconsolidation of Aliança Energia. These impacts were partly offset by ongoing efficiency gains, which helped mitigate external headwinds.

Vale's average maritime freight cost was US$ 22.8/t in 3Q26, US$ 0.8/t higher q/q, mainly due to higher bunker fuel costs (US$ 0.5/t higher q/q) and increased exposure to spot freight rates (US$ 0.3/t higher q/q), driven by seasonally higher sales in the second semester. CFR sales totaled 68.2 Mt in 3Q26, accounting for 90% of total iron ore fines sales. Vale's freight strategy continued to mitigate the impact of higher freight market volatility during the quarter. The Company's shipping requirements are predominantly covered by long-term contracts at freight-fixed rates, reducing direct exposure to spot freight rates. At the same time, fleet optimization initiatives and the use of larger, more fuel-efficient vessels support a competitive freight cost position. In 3Q26, Vale's freight costs remained US$ 14/t below the Brazil–China C3 route. As part of Vale's ongoing risk management strategy, Vale hedged approximately 70% of its forecasted bunker oil consumption for 2026 through Brent crude oil contracts. Considering the economic effect of these contracts in 3Q26, combined with forward freight agreements, the benefit on all-in cost per ton of iron ore, was approximately US$ 1.4/dmt. Adjusting for this effect, Vale’s all-in cost in 3Q26 would be equivalent to US$ 59.0/dmt, compared with the reported US$ 60.4/dmt, helping offset the impact of higher freight costs.

Copper EBITDA increased by 66% y/y, totaling US$ 1.0 billion in the quarter, driven by higher realized prices for copper (US$ 385 million) and by-products (US$ 80 million). These positive effects were partly offset by maintenance costs associated with the Sossego SAG mill rebuild (US$ -40 million) and the negative impact of the BRL appreciation (US$ -19 million). Nickel EBITDA decreased by 14% y/y, totaling US$ 98 million in the quarter, (i) higher own-sourced feed costs (US$ ‑109 million), reflecting the inventory turnover of higher unit production costs from 2Q26 and lower nickel grades consistent with the mine plans, (i) higher external feed prices (US$ -69 milion), and ( i) planned maintenance costs (US$ ‑33 milion).

Unit COGS were US$ 6,721/t, 8% higher y/y, driven by the Sossego SAG mill rebuild costs (US$ +576/t) and the BRL appreciation (US$ +258/t). These effects were partly offset by higher fixed-cost dilution at Salobo (US$ -295/t), reflecting its strong operational performance. All-in costs totaled US$ -175/t in the quarter, US$ 1,169/t lower y/y and largely in-line q/q. The year-on-year improvement was mainly driven by higher unit by-product revenues (US$ -1,065/t) and the effect of the recovery of tax credits related to Salobo (US$ -143/t), included in other expenses, which offset the unit COGS effect mentioned above.

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.
