Lithium Americas Announces Offering of US$225 Million Convertible Senior Notes

VANCOUVER, Nov. 30, 2021 - Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) ("Lithium Americas" or the "Company") today announced that it proposes to offer US$225,000,000 aggregate principal amount of convertible senior notes due 2027 (the "Notes" and the "Offering"), subject to market conditions and other factors. The Company intends to grant the initial purchasers of the Notes an option to purchase up to an additional US$33,750,000 aggregate principal amount of Notes, exercisable in whole or in part at any time until 30 days after the closing of the Offering.

The Notes will be unsecured and will accrue interest payable semi-annually in arrears and will mature on January 15, 2027, unless earlier repurchased, redeemed or converted.

The Notes will be convertible at the option of holders, prior to the close of business on the business day immediately preceding October 15, 2026, only under certain circumstances and during certain periods, and thereafter, at any time until the close of business on the business day immediately preceding the maturity date. Upon conversion, the Notes may be settled, at the Company's election, in cash, common shares ("Common Shares") of the Company or a combination thereof. The Notes will not be redeemable at the Company's option prior to December 6, 2024, except upon the occurrence of certain tax law changes. On or after December 6, 2024, the Notes will be redeemable at the Company's option if the last reported sale price of the Common Shares has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

If the Company undergoes a fundamental change, holders of the notes will have the right to require the Company to repurchase for cash all or a portion of their notes at 100% of their principal amount, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The Company will also be required, in certain circumstances, to increase the conversion rate for a holder who elects to convert its notes in connection with certain corporate events or during a redemption period.

The interest rate, initial conversion rate and other terms of the Notes will be determined at the time of pricing of the Offering.

Completion of the Offering will be subject to various conditions, including the approval of the Toronto Stock Exchange (the "TSX") and the New York Stock Exchange (the "NYSE"). For the purposes of TSX approvals in connection with the Offering, the Company intends to rely on the exemption set forth in Section 602.1 of the TSX Company Manual, which provides that the TSX will not apply its standards to certain transactions involving eligible interlisted issuers on a recognised exchange, such as the NYSE.

The Company intends to use the net proceeds from the Offering to repay its indebtedness, including certain amounts owing under its amended and restated credit and guarantee agreement dated July 14, 2017 between the Company (as borrower) and 2265866 Ontario Inc., Lithium Nevada and KV Project LLC (as guarantors), BCP Innovation PTE. Ltd. (an affiliate of Bangchak Public Company Ltd.) and Ganfeng Lithium Co. Ltd. (as lenders), BNY Trust Company of Canada (as the administrative agent for the lenders) and The Bank of New York Mellon (as the U.S. Collateral Agent for the lenders), and for general corporate purposes.

The Notes will be offered on a private placement basis and will not be offered by way of a prospectus in Canada, the U.S., or any other jurisdiction. The Notes and the distribution of Common Shares issuable upon conversion of the Notes have not been, and will not be, registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws and may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and the rules promulgated thereunder and applicable state securities laws. The Notes will be offered (i) to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act and (ii) outside the United States to non-U.S. persons in reliance on Rule 903 of Regulation S under the Securities Act, and, in the case of offers in Canada, to persons who are "accredited investors" and "permitted clients" within the meaning of Canadian securities laws.

This news release does not constitute an offer to sell or a solicitation of an offer to buy the Notes or any other securities and shall not constitute an offer, solicitation or sale in the United States or in any other jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration and qualification under the securities laws of such state or jurisdiction. The Offering may be made only by means of an offering memorandum.
