Filing text preview

Vale S.A. filed Form 6-K/A on October 29, 2025, disclosing its Internal Audit Charter (POL-0029-G, Version 02). The charter establishes the independence, objectivity, and scope of internal audit activities, with the Chief Audit and Compliance Officer reporting directly to the Board of Directors and oversight by the Audit and Risks Committee. It covers audit planning, execution, reporting, and action plan monitoring, requiring regular quality assessments and prohibiting auditors from assuming operational responsibilities. This move aims to strengthen corporate governance and risk management.
