South32 Limited, the diversified mining company incorporated in Australia and listed on the Australian Securities Exchange, London Stock Exchange and Johannesburg Stock Exchange, filed a daily buy-back notification on 6 November 2026. The Appendix 3C update was lodged with the ASX and voluntarily disclosed on the JSE and LSE before being submitted to the UK Financial Conduct Authority's National Storage Mechanism. The filing confirms that South32's ongoing share repurchase programme remains active, a development investors in the mining sector may monitor closely given the company's cross-listed status across three major exchanges.

South32's Appendix 3C Buy-Back Filing Submitted to FCA National Storage Mechanism

South32 lodged its Appendix 3C daily buy-back notification with the Australian Securities Exchange on 6 November 2026 and simultaneously made a voluntary disclosure on both the Johannesburg Stock Exchange and the London Stock Exchange. The filing has been submitted to the FCA's National Storage Mechanism, where it will be available for public inspection at the FCA's data portal. The company's JSE sponsor for the disclosure is The Standard Bank of South Africa Limited. The specific number of shares repurchased and the transaction value were not disclosed within this announcement.

South32's Operations Across the Americas, Australia and Southern Africa Underpin the Buy-Back

South32 is a diversified natural resources company incorporated in Australia under the Corporations Act 2001. It produces minerals and metals that it describes as critical to the global energy transition, operating mines and processing facilities across the Americas, Australia and Southern Africa. The company's revenue is generated from the sale of these commodities, and it is also engaged in exploring and developing its next generation of mine assets. This operational breadth across multiple continents and regulatory jurisdictions underpins its tri-exchange listing structure and informs the cross-market reporting obligations attached to its buy-back programme.

Voluntary JSE and LSE Disclosure Reflects South32's Multi-Exchange Reporting Obligations

Because South32 carries primary and secondary listings on three major exchanges simultaneously, its share repurchase notifications carry reporting requirements that extend beyond a single regulatory regime. The voluntary disclosure to the LSE and JSE, alongside the mandatory ASX lodgement, ensures transparency for shareholders across all three markets. Investors on each exchange are therefore able to access the same buy-back information contemporaneously. The frequency of these daily Appendix 3C updates means the cumulative progress of the repurchase programme will become clearer as successive filings accumulate over the duration of the buy-back.
