Vale updates on railway concession contracts negotiations

Rio de Janeiro, April 16, 2026 – Further to the Company's prior disclosures on this matter<sup>1</sup>, Vale S.A. ("Vale" or the "Company") announces that its Board of Directors approved, on this date, the continuation, by the Company's Executive Committee, of negotiations concerning the optimization of the concession contracts of the Carajás Railway (Estrada de Ferro Carajás – EFC) and the Vitória a Minas Railway (Estrada de Ferro Vitória a Minas – EFVM) (the "Concession Contracts"). These discussions are being held with the Brazilian Ministry of Transport (MT), the National Land Transportation Agency (ANTT) and Infra S.A. ("INFRA"), within the scope of their respective legal authorities.

Vale reaffirms its commitment to the guidelines and general framework for the optimization process set forth in the agreement entered into on December 30, 2024, notably with respect to the asset base and infrastructure works. The Company is in full compliance with, and will continue to fully perform, all obligations provided for under the Concession Contracts. The conclusion of the Concession Contracts optimization, when approved by the Federal Court of Accounts (TCU), is expected to provide greater predictability, legal certainty, and finality with respect to the obligations and investments associated with Vale's two railway concessions, ensuring an appropriate balance between the Company's rights and liabilities and contributing to its long-term operational efficiency, as well as to the sustainability of its integrated logistics system.
