FINANCIAL RESULTS

Selected consolidated financial information is presented as follows:

Net income in Q2 2023 versus loss in Q2 2022 is primarily due to lower share of loss of Caucharí-Olaroz project partially offset by lower gain on change in fair value of the GM agreements derivative liability and convertible note derivative liability.

In H1 2023, total assets increased primarily due to acquisition of Arena Minerals and cash proceeds from the first tranche investment by GM of $320 million.

This news release should be read in conjunction with Lithium Americas' condensed consolidated interim financial statements and management's discussion and analysis for the quarter ended June 30, 2023, which are available on SEDAR. All amounts are in U.S. dollars unless otherwise indicated.
