Sumitomo Metal Mining raises capital for Australian subsidiary's Winu project

Sumitomo Metal Mining announced its decision to increase capital in SMM Perth PTY LTD, a subsidiary established on January 13, 2025. This capital increase will result in SMM Perth PTY LTD's capital exceeding 10% of SMM's capital, thus classifying it as a specified subsidiary. The capital injection is for SMM Perth PTY LTD to fund its participation in the Winu Copper-Gold Project in Western Australia, where SMM intends to acquire a 30% interest from a Rio Tinto plc subsidiary, pending regulatory approval.

The total payment for the capital increase will be $197,800,000 and A$104,000,000, with the payment scheduled for late October 2025. Following the capital increase, SMM Perth PTY LTD's capital will be $197,800,000 and A$104,000,010. Sumitomo Metal Mining will maintain a 100% ownership stake in SMM Perth PTY LTD.

Sumitomo Metal Mining anticipates that this capital increase will have a minor impact on its current fiscal year's performance and financial condition.
