Item 1 Comment:
Item 1 of the Schedule 13D is hereby amended and restated as follows:
This Schedule 13D relates to the Common Shares of the Issuer. The principal executive offices of the Issuer are located at Dammstrasse 19, 6300 Zug, Switzerland.
On October 3, 2023, the Issuer completed the planned separation of its U.S. and Argentina businesses (the "Separation"), pursuant to which two public companies were established. As a result of the Separation, the Issuer changed its name from "Lithium Americas Corp." to "Lithium Americas (Argentina) Corp." and established a new publicly traded entity, named "Lithium Americas Corp." ("Spinco"). In connection with the Separation, the Issuer transferred the Thacker Pass lithium project located in Humboldt County, Nevada (the "Thacker Pass Project") to Spinco.
On January 23, 2025, the Issuer completed a plan of arrangement under the laws of the province of British Columbia (the "Arrangement") involving the Issuer's continuation from the province of British Columbia under the name "Lithium Americas (Argentina) Corp." into Zug, Canton of Zug, Switzerland, as a Swiss share corporation under the name "Lithium Argentina AG." Following the Arrangement, the shareholders of the Issuer prior to the Arrangement continued to hold all the issued and outstanding registered common shares of the Issuer.
