By Brazil Stock Guide – Vale (B3: VALE3, NYSE: VALE) will record an additional US$500 million provision linked to the 2015 Fundão dam collapse after the UK High Court ruled that both Vale and BHP can be held liable under Brazilian law. The new charge adds to the US$2.401 billion already recognized by September 2025 and underscores that international litigation remains the company’s main financial risk even as domestic reparations advance.
Ruling Narrows Claimants but Extends the Timeline
The court upheld waivers signed by approximately 240,000 individuals already compensated in Brazil, removing a large portion of the UK claimant pool. Even so, the litigation will continue for years. A second trial on causation and general damages is scheduled from October 2026 to March 2027, with a potential third phase for individual damages only after appeals, likely not before 2028.
Vale said its cost-sharing agreement with BHP ensures a 50/50 split of any amount payable in the UK and Dutch actions, reducing asymmetry but not shortening the litigation cycle.
Brazil Agreement Remains the Central Framework
Vale reiterated that the R$170 billion (US$32 billion) Doce River settlement signed in October 2024 remains the primary framework for environmental and social remediation. Reconstruction of Bento Rodrigues and Paracatu is 98% complete, environmental recovery is considered advanced, and more than 610,000 people have been compensated since 2015. To date, BHP Brasil, Vale and Samarco have committed US$13 billion to compensation, financial support and restoration projects.
BHP’s Appeal and Provision Update
On the other side of the case, BHP (NYSE/LSE/ASX: BHP) said it will appeal the ruling and continue to defend the UK group action as it moves into second and third trials expected to run into 2028–29.
BHP will update its provision related to the dam failure, now estimated at US$5.5 billion as of 31 October 2025, compared with US$5.8 billion in June. The figure includes US$1 billion already spent since July, adjustments under the Brazil Agreement and the impact of the ruling. Expected Samarco cash outflows remain around US$2.2 billion in FY2026 and US$0.5 billion in FY2027.
The court found BHP liable as a “polluter” under Brazilian environmental law and at fault under the Civil Code, while rejecting liability under corporate law. It also upheld the waivers signed by around 240,000 compensated claimants, which BHP says should materially reduce the size and value of the UK group action involving over 600,000 plaintiffs.
Background: The Fundão Disaster
The Fundão dam operated by Samarco — jointly owned by Vale and BHP Brasil — collapsed in November 2015, killing 19 people and releasing mining waste that contaminated over 600 km of rivers in the Doce River Basin. It remains one of Brazil’s worst environmental disasters and the basis for ongoing legal actions in Brazil, the UK and the Netherlands.
