BRISBANE - Allkem Limited (ASX and TSX: AKE, 'Allkem') refers to the proposed merger of equals between Allkem and Livent Corporation ('Livent'), ('Transaction').

Allkem is pleased to announce that it has today lodged with the Australian Securities and Investments Commission a copy of the orders of the Federal Court of Australia ('Orders') approving the scheme of arrangement pursuant to which Arcadium Lithium plc ('Arcadium Lithium') will acquire 100% of the shares in Allkem ('Scheme') in connection with Transaction.

As a result, the Scheme is now legally effective.

Eligibility to receive Scheme Consideration

On implementation of the Scheme, Allkem shareholders (other than ineligible overseas shareholders) who are registered as such on the Scheme Record Date (being 7:00 pm (AEDT) on 27 December 2023) will receive: in the case of Allkem principal register shareholders, one Arcadium Lithium CDI for each Allkem Share held, unless they have validly elected to receive Arcadium Lithium shares instead and in the case of Allkem Canadian branch register shareholders, one Arcadium Lithium share for each Allkem Share held, unless they validly have elected to receive Arcadium Lithium CDIs instead.

Ineligible overseas shareholders will not receive Arcadium Lithium Shares or Arcadium Lithium CDIs under the Scheme, and will instead receive their share of the net proceeds from the sale of Arcadium Lithium CDIs by the Sale Nominee.
