Vale informs on estimates update Rio de Janeiro, June 9, 2026 – Vale S.A. (“Vale” or the “Company”) informs that it has updated the indicative guidance on the potential contribution of its subsidiary Vale Base Metals Ltd. (“VBM”) to the Company’s consolidated EBITDA in the long term, which is now approximately 28%. This estimate considers, as main assumptions, the 2026 average prices of copper, nickel and gold, based on the average of sell-side analysts’ estimates available in May 2026. All other estimates disclosed by the Company in item 3 of its Reference Form remain unchanged. The aforementioned item of the Reference Form will be refiled with the above update in due course, in compliance with the deadline set forth in CVM Resolution No. 80/2022. Vale clarifies that the information in this Press Release consists of estimates and forward-looking statements based on assumptions and hypothetical data, and should not be interpreted as promise, guarantee or commitment regarding the Company’s or its management’s future performance. Actual results may differ materially due to market conditions, macroeconomic factors, operational performance and other risks described in the Company’s periodic filings with the CVM and the SEC.
