Lawsuit challenges a rail segment, but Vale sees no material impact yet.

The disclosure centers on a lawsuit by Brazil’s Federal Prosecutor’s Office seeking to suspend operations on a 16‑km section of the second Carajás Railroad line. Vale notes it has responded in court and will present a full defense.

Carajás is a key logistics corridor, so any mandated suspension could affect iron ore flows, yet Vale explicitly states the matter does not currently create a relevant operational impact. Actual consequences will depend on judicial decisions and any required operational changes.

Vale highlights transparency and cooperation with authorities and commits to update the market on material developments, so future company reports and regulatory communications will be important to understand whether this legal action evolves into an operational or financial constraint.
