Lithium Americas Prices US$275 Million Underwritten Public Offering

Lithium Americas Corp. (TSX: LAC) (NYSE: LAC)

(“

Lithium Americas

” or the “

Company

”) announced the pricing of its previously announced underwritten public offering (the “

Offering

”) of 55,000,000 of its common shares (the “

Common Shares

”) at a price to the public of $5.00 per Common Share (the “

Issue Price

”) for aggregate gross proceeds to the Company of $275,000,000.

The Offering is being conducted through a syndicate of underwriters led by Evercore ISI, Goldman Sachs & Co. LLC and BMO Capital Markets (together, the “Lead Underwriters”), as the co-lead book-running managers, J.P. Morgan as joint book-running manager, and Canaccord Genuity, Cormark Securities Inc., Scotiabank, Stifel Canada, Eight Capital and Tuohy Brothers as co-managers (together with the Lead Underwriters, collectively, the “Underwriters”).

The Company has granted the Underwriters an option to purchase up to 8,250,000 additional Common Shares (the “Over-Allotment Option”) at the Issue Price, exercisable, in whole or in part, for up to 30 days after the closing of the Offering.

The Company intends to use the net proceeds of the Offering for advancing the construction and development of its Thacker Pass lithium project in Humboldt County, Nevada (“Thacker Pass”), as further described in the Prospectus Supplements.

In March 2024, the Company achieved a significant milestone for Thacker Pass by receiving a conditional commitment (the “Conditional Commitment”) from the U.S. Department of Energy under the Advanced Technology Vehicles Manufacturing Loan Program (the “ATVM Loan Program”) for a $1.97 billion loan in aggregate principal to fund eligible construction costs of the processing facilities at Thacker Pass, targeting to produce an initial 40,000 tonnes per year of battery grade lithium carbonate (“Phase 1”), plus interest to be accrued during construction, which is estimated to be $290 million over a three-year period, together totaling a $2.26 billion loan (the “Loan”). As of December 31, 2023, after accounting for funding from the Loan and the pending $330 million second tranche investment (the “Tranche 2 Investment”) from General Motors Holdings LLC (“GM”), the Company estimates approximately $436 million remains to be committed to Phase 1 capital costs from the Company's existing cash and cash equivalents and incremental funding. The Company’s approximately $196 million of cash and cash equivalents, as of December 31, 2023, when combined with the net proceeds of the Offering of approximately $263 million (before giving effect to any exercise of the Over-Allotment Option), along with and after accounting for the funding from the Loan and the GM Tranche 2 Investment, are expected to result in the estimated remaining capital expenditures of approximately $2.736 billion for construction of Phase 1 as well as the Company’s 2024 operating budget being substantially fully funded. Incremental funding requirements will be funded through the exercise of the Over-Allotment Option (if exercised) or other financing alternatives.

Closing is expected to occur on April 22, 2024, and is subject to customary closing conditions, including receipt of required approvals of the Toronto Stock Exchange and the New York Stock Exchange.

The Offering will be made in the United States by way of a prospectus supplement (the “U.S. Prospectus Supplement”) to the Company’s existing base shelf prospectus (the “U.S. Base Shelf Prospectus”) forming part of an effective registration statement on Form F-3 (File No. 333-274883) (the “Registration Statement”), and will be made in Canada by way of a prospectus supplement (the “Canadian Prospectus Supplement”, together with the U.S. Prospectus Supplement, the “Prospectus Supplements”) to the Company’s existing base shelf prospectus (the “Canadian Base Shelf Prospectus”, together with the U.S. Base Shelf Prospectus, the “Base Shelf Prospectuses”). The Offering is being made in the United States and in each of the provinces and territories of Canada, except Québec.
