Acquisition by Harmony Gold (Australia) Pty Ltd

MAC Copper Limited entered into a binding implementation deed with Harmony Gold Mining Company Limited and its wholly owned subsidiary Harmony Gold (Australia) Pty Ltd (Harmony Australia). Under this arrangement, Harmony Australia agreed to acquire 100% of the issued share capital of MAC Copper Limited by way of a Jersey law scheme of arrangement pursuant to Article 125 of the Companies (Jersey) Law 1991. Company announcements describe this transaction as a proposed acquisition of all MAC shares by Harmony Australia.

Subsequent MAC Copper Limited announcements report that the Royal Court of Jersey made orders sanctioning the scheme of arrangement and that MAC lodged the Court’s order with the Jersey Registrar of Companies. MAC Copper Limited disclosed that, as a result, the scheme became legally effective on October 10, 2025. The company further reported that MAC CDIs would be suspended from trading on the ASX from close of trading on October 10, 2025 and that this date would also be the last day of dealings in MAC shares on the NYSE.

MAC Copper Limited’s timetable disclosures indicated that the delisting process would include suspension of quotation of MAC CDIs on the ASX, initiation of delisting of MAC shares from the NYSE (with a Form 25-NSE to be filed by the NYSE), and completion of delisting of MAC shares from the NYSE. The company also outlined dates for the implementation of the scheme, payment of consideration to holders of MAC shares and CDIs, and the delisting of MAC from the ASX.

Termination of SEC Registration and Reporting Obligations

Following the completion of the acquisition by Harmony Australia, MAC Copper Limited filed a Form 15 with the SEC. In this filing, the company certified the termination of registration of its ordinary shares under Section 12(g) of the Securities Exchange Act of 1934 and the suspension of its duty to file reports under Sections 13 and 15(d) of the Exchange Act. The Form 15 notes that, effective as of October 10, 2025 and implemented on October 24, 2025, Harmony Australia acquired 100% of the issued share capital in MAC Copper Limited pursuant to the Jersey law scheme of arrangement. The filing also indicates that the approximate number of holders of record as of the certification or notice date was one, reflecting the post-acquisition ownership structure.

As a result of this transaction and subsequent deregistration, MAC Copper Limited’s ordinary shares are no longer registered under Section 12(g) of the Exchange Act, and the company has suspended its periodic reporting obligations to the SEC. Historical SEC filings, including Form 6-K current reports and the Form 15, provide a regulatory record of MAC Copper Limited’s transition from a listed foreign private issuer to a wholly owned subsidiary of Harmony Gold Mining Company Limited.
