Amendment Description	On March 18, 2024, Lithium Americas Corp. (the “Company”) filed its Annual Report on Form 20-F for the fiscal year ended December 31, 2023 (the “Original Form 20-F”). This Amendment No. 1 (the “Amendment”) amends the Original Form 20-F solely to revise the consent of our independent registered public accounting firm, PricewaterhouseCoopers LLP (“PwC”), filed originally as Exhibit 15.10 of the Original Form 20-F. The consent included in the Original Form 20-F inadvertently omitted the signature of PwC. The revised consent of PwC is filed hereto as Exhibit 15.1. In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company is including the certifications required under the Sarbanes-Oxley Act of 2002 in Item 19 of this Amendment. Other than with respect to the foregoing, this Amendment speaks as of the filing date of the Original Form 20-F and does not reflect any other events occurring after the filing of the Original Form 20-F. No revisions are being made to the Company’s financial statements or any other disclosure contained in the Original Form 20-F. This Amendment does not otherwise update any other exhibits as originally filed.
