BHP said in November 2025 that the UK group action duplicates remediation and compensation already provided in Brazil or available under the Brazil agreement.

BHP believes the UK group action is duplicative of remediation and compensation

Why this label

BHP's release states this belief^S3. The Brazilian agreement is large, at BRL 170 billion on a 100 percent basis^S4, and it was ratified by the Brazilian Supreme Court^S5. BHP's own October 2024 release lists the UK group action among claims the agreement does not resolve^S4. The liability judgment did not decide how much, if anything, claimants can recover after Brazilian payments. That question belongs to the damages phase, reported for April 2027^S7 and placed by the Court of Appeal in the second part of 2027 into 2028^S2. No court has yet ruled on the extent of overlap. The records do not permit a conclusion.

Current procedural position

Overlap with Brazilian compensation not yet decided. Damages trial expected in 2027^S2^S7.

Record supporting the assessment

BHP believes the UK group action is duplicative of remediation and compensation that has already occurred in Brazil or which is available under the Brazil Agreement.
