On November 13, 2025, Lithium Americas Corp., a company incorporated under the laws of British Columbia, Canada (the “Company”), entered into an Equity Distribution Agreement (the “Agreement”) with TD Securities (USA) LLC (the “Agent”), as sales agent and/or principal, pursuant to which the Company may offer and sell, from time to time, through the Agent, its common shares, without par value (the “Common Shares”), having an aggregate offering price of up to US$250,000,000 (the “ATM Program”).

The Company is not obligated to sell any Common Shares under the Agreement. Subject to the terms and conditions of the Agreement, the Agent will use commercially reasonable efforts, consistent with their normal trading and sales practices and applicable laws and regulations to sell Common Shares from time to time based upon the Company’s instructions, including any price, time or size limits specified by the Company, subject to certain limitations. Under the Agreement, the Agent may sell the Common Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended (the “Securities Act”), including block transactions, sales made directly on or through the New York Stock Exchange or sales made into any other existing trading market of the Company’s Common Shares.

The Common Shares will be issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-287327) initially filed by the Company with the U.S. Securities and Exchange Commission (the “SEC”) on May 15, 2025 (the “Registration Statement”), and declared effective by the SEC on May 23, 2025, and related prospectus supplements to be prepared and filed pursuant to Rule 424(b) from time to time in connection with the offer and sale of the Common Shares. A prospectus supplement (the “Prospectus Supplement”), dated November 13, 2025, covering the offer and sale of the Common Shares having an aggregate offering price of up to US$250,000,000 was filed with the SEC on the date hereof.

The Company will pay the Agent a commission up to 3.0% of the gross proceeds from each sale of Common Shares, reimburse legal fees and disbursements and provide the Agent with customary indemnification and contribution rights. The Agreement will be effective until the earlier of the issuance and sale of all of the Common Shares issuable pursuant to the ATM Program and the date that the ATM Program is otherwise terminated pursuant to the terms of the Agreement.

The Company intends to use the net proceeds from any offerings, if any, for general corporate purposes, which may include funding of corporate and project overhead expenses, financing of capital expenditures, repayment of indebtedness and additions to working capital.

The foregoing description of the Agreement in this Current Report on Form 8-K does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, which is filed as Exhibit 1.1 hereto and is incorporated herein by reference.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy any Common Shares under the Agreement nor shall there be any sale of such Common Shares in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

A copy of the legal opinion of Cassels Brock & Blackwell LLP relating to the validity of the issuance and sale of the Common Shares under the ATM Program is filed as Exhibit 5.1 to this Current Report on Form 8-K and is filed with reference to, and is hereby incorporated by reference into, the Registration Statement.
