Investors

Prior to its acquisition by Rio Tinto in March 2025 for $6.7B, institutional investors held approximately 65.0% of Arcadium Lithium’s shares. The largest institutional investors were BlackRock, Inc. (12.0%), The Vanguard Group, Inc. (11.0%), and State Street Global Advisors, Inc. (3.5%). Other notable buyers in the 24 months before the acquisition included CIBRA Capital Ltd, Comprehensive Money Management Services LLC, and Wealth Enhancement Advisory Services LLC, while Wellington Management Group LLP and the California State Teachers Retirement System were among the significant sellers. Hedge fund ownership remained minimal. Rio Tinto’s acquisition made it the ultimate controlling shareholder.
