Insights

Neutral: $765M cash deal for 30% lithium stake, pending approvals.

POSCO HOLDINGS plans to invest USD 765,000,000 (KRW 1.112T) for a 30% interest in a new Australian intermediate holding company tied to Mineral Resources Ltd. The board approved on November 11, 2025, positioning the group to support lithium cost competitiveness.

While strategic, the filing quantifies the size at 1.8% of equity capital, suggesting modest balance-sheet impact. Execution depends on merger filings in Australia/China and FIRB approval in Australia; actual closing will hinge on these clearances and final agreements.

The filing lists a cash acquisition method and no option structures. Subsequent filings may provide the incorporation details and final schedule once regulatory steps are completed.
