Arcadium Lithium gets shareholder nod for $6.7bn buyout by Rio Tinto

US lithium producer Arcadium Lithium has secured shareholder approval for its acquisition by mining giant Rio Tinto in an all-cash transaction valued at around $6.7bn.

The deal, announced in October this year, would make Rio Tinto one of the world’s largest lithium suppliers.

Rio Tinto agreed to acquire Arcadium for $5.85 per share, marking a 90% premium to the latter’s closing price on 4 October 2024.

Arcadium will offer Rio Tinto access to “long-life, low-cost” in various geographies, including Argentina, Australia, Canada, China, Japan, the US, and the UK.

Rio Tinto looks to use its scale and financial strength to unlock the complete potential of Arcadium’s portfolio.

The deal has already secured the green light from the two companies’ boards.
