LITHIUM AMERICAS ANNOUNCES FILING OF CIRCULAR IN CONNECTION WITH THE SEPARATION AND AGM

Lithium Americas Corp. has filed the management information circular in connection with the annual general and special meeting of Lithium Americas shareholders to be held on July 31, 2023. The meeting will be held to consider the approval of the reorganization of the company that will result in the separation of its North American and Argentine business units into two independent public companies and annual meeting matters, among other things.

The separation will establish the company as Lithium Americas (Argentina) Corp., as well as a new company to be named Lithium Americas (NewCo). Lithium Argentina will retain the company's Argentina portfolio, which is advancing the Cauchari-Olaroz project to full production following the recent achievement of first lithium, while pursuing regional growth through development of the Pastos Grandes basin. Lithium Americas (NewCo) will become a leading North American-focused lithium company advancing the 100-per-cent-owned Thacker Pass project through construction to production to support the development of the North American lithium supply chain.

The separation has strong shareholder support, with shareholders holding in aggregate approximately 23.8 per cent of outstanding common shares of Lithium Americas having agreed to vote in favour of the separation, including General Motors Holdings LLC, GFL International Co. Ltd., and officers and directors of Lithium Americas.

The board of directors of the company recommends that shareholders vote in favour of the separation and other matters presented at the meeting.

The separation is targeted to become effective by Oct. 15, 2023, but in any event no later than Dec. 31, 2023. Completion of the separation is subject to a number of regulatory approvals and closing conditions, including approvals by the Supreme Court of British Columbia, the Toronto Stock Exchange and the New York Stock Exchange, and receipt of tax rulings from the Canada Revenue Agency and Internal Revenue Service, amongst other things. The timing of these approvals and satisfaction of closing conditions have the potential to impact the timing of the completion.
