Vale informs on estimates update Rio de Janeiro, May 12th, 2026 - Vale S.A. ("Vale" or the "Company") informs the market of the update of its estimates, which now include: (i) the free cash flow variation of the Iron Ore Solutions segment in 2026, considering the market conditions resulting from the conflict in the Middle East; and (ii) the EBITDA and cash flow sensitivities of the Nickel segment of Vale Base Metals Ltd. ("VBM"). These estimates are part of a presentation to be delivered by the Company on this date at the Bank of America Metals, Mining and Steel Conference in the United States. Iron Ore Solutions – 2026 free cash flow variation (US$ million): Considering the market conditions observed before and after the onset of the conflict in the Middle East, the Company estimates an increase of approximately US$1.5 billion in free cash flow in 2026, comprised of: (i) an increase of approximately US$1.2 billion in the segment's EBITDA; (ii) generation of approximately US$425 million through foreign exchange and fuel hedging programs; and (iii) an increase of approximately US$0.1 billion in sustaining capital expenditures. This estimate assumes the following premises: (i) pre-conflict scenario: average prices of January and February 2026 applied to 2026 full year: iron ore at US$102/t, Brent at US$67/bbl, bunker at US$490/t, and BRL/USD exchange rate of 5.27; and (ii) post-conflict scenario: realized performance between January and April 2026 and spot prices applied to the period from May to December 2026: iron ore at US$112/t, Brent at US$104/bbl, bunker at US$675/t, and BRL/USD exchange rate of 4.90. Nickel – EBITDA generation sensitive to price, per year (in US$ million per tonne): Nickel price (US$/tonne) 16,000 18,000 20,000 2026 ~1,150 ~1,550 ~2,000 2027 ~1,600 ~2,000 ~2,450 Nickel – Free cash flow generation sensitive to price, per year (in US$ million per tonne): Nickel price (US$/tonne) 16,000 18,000 20,000 2026 ~5 ~350 ~700 2027 ~300 ~650 ~1,000 The estimates for the Nickel segment above assume, as reference, analysts' consensus prices for 2026 of: US$12,660/t for copper; US$54,650/t for cobalt; US$5,000/troy ounce for gold; US$2,170/troy ounce for platinum; and US$1,680/troy ounce for palladium; and, for 2027, of: US$12,220/t for copper; US$48,550/t for cobalt; US$5,000/troy ounce for gold; US$2,070/troy ounce for platinum; and US$1,500/troy ounce for palladium. All other estimates set forth in item 3 of the Company's Reference Form remain unchanged. The aforementioned item will be refiled in due course to reflect the updates above, in accordance with the deadlines established under CVM Resolution No. 80/2022.
