Vale decides to temporarily halt the Teluk Rubiah Maritime Terminal

Rio de Janeiro, March 23th, 2020 — Vale S.A. (“Vale”) informs that decided to temporarily halt, starting on Tuesday, March 24th, its distribution center in Malaysia (the Teluk Rubiah Maritime Terminal, “TRMT”, 23.7 Mt of Iron Ore shipped in 2019) at least until March 31st. Vale took this decision as it is temporarily unable to secure the minimum resources to safely operate the terminal.

Vessels heading to the TRMT will be redirected and redistributed among our blending facilities in China with no expected impact on production and sales volume in 2020, but with an impact on sales of approximately 500,000 t in 1Q20. An immaterial cost increase is expected due to additional logistics.

Vale reaffirms its commitment to the safety of its people and the communities in which it operates and will keep investors and markets informed of future developments.
