ASX-listed lithium miner Allkem's merger with US-based Livent is set to go into effect in a fortnight after shareholders from both companies approved the $9.7 billion deal.
The new company will begin operating under the name Arcadium Lithium on January 4.
Arcadium will have a primary listing on the New York Stock Exchange, with CHESS depository interests (CDIs) traded on the ASX.
