The deal is advancing toward the October 15 shareholder vote with no new material developments. Monitor the vote outcome and regulatory approvals (FIRB, ACCC, etc.) as key catalysts. Post-vote, the primary risk is regulatory delay or failure, which could trigger a break fee of up to US$82M for South32.
