Ogier advises Arcadium Lithium in its $6.7 billion buyout by Rio Tinto

A multi-disciplinary team from Ogier in Jersey has advised global lithium producer Arcadium Lithium on its $6.7 billion acquisition by Rio Tinto.

Shareholders approved the transaction in December 2025, with the Royal Court of Jersey sanctioning the scheme on 5 March 2025 and the transaction completing on 6 March 2025.

The deal makes Rio Tinto, an Anglo-Australian mining company, one of the world's largest producers of lithium and a global leader in energy transition commodities.

The deal was implemented by way of a Jersey scheme of arrangement.

The Ogier deal team was led by Corporate partners Simon Dinning and Alexander Curry, with support from managing associate Alex Fisher. The team also included Dispute Resolution partner James Angus, senior associate Matthew Davies and associate William Greenall. The team worked alongside lead counsel Davis Polk & Wardwell LLP.

"This is a high profile and significant transaction for the long-term future of the lithium market. We're very pleased to have advised," said Alexander Curry. 

Arcadium is one of the world’s leading global lithium producers. Ogier advised on its formation at the beginning of 2024 following the merger of Livent and Australian miner Allkem.
