MATERIAL CHANGE REPORT

Lithium Americas Corp. (“Lithium Americas” or the “Company”) 300 - 900 West Hastings Street Vancouver, BC, V6C 1E5

February 7, 2020

A news release with respect to the contents of this report was issued on February 7, 2020 and was disseminated through the facilities of recognized newswire services. A copy of the news release was filed on SEDAR.

On February 7, 2020, the Company entered into definitive agreements with Ganfeng Lithium Co., Ltd. (together with its subsidiaries, “Ganfeng Lithium”) in respect of their joint venture company, Minera Exar S.A. (“Minera Exar” or “JV”) (collectively, the “Transaction”). Minera Exar owns 100% of the Caucharí-Olaroz lithium project (“Caucharí-Olaroz” or the “Project”) currently under construction in Jujuy, Argentina. The Transaction includes the following provisions:

• Ganfeng Lithium has agreed to subscribe for new shares of Minera Exar for cash consideration of US$16 million increasing its interest from 50% to 51%, with Lithium Americas owning the remaining 49%.

• Both parties have agreed to the 2020 funding schedule, including investment of up to US$400 million, in accordance with the 2019 approved construction plan.

• Joint venture and related agreements will be amended as a result of the new ownership structure to preserve joint approval for substantive matters involving Minera Exar and to maintain the existing construction plan and management team.

• Lithium Americas will receive US$40 million in cash from the proceeds of non- interest-bearing loans provided by Ganfeng Lithium to one of the JV entities.

Under the terms of the Transaction, Ganfeng Lithium has agreed to subscribe for new shares of Minera Exar for cash consideration of US$16 million. Proceeds will be used by Minera Exar for the purpose of advancing the construction and development of Caucharí-Olaroz. Upon completion of the Transaction, the Company and Ganfeng Lithium will own 49% and 51% of Minera Exar, respectively.

In addition, Lithium Americas and Ganfeng Lithium have agreed to restructure Exar Capital BV (“Exar Capital”), a jointly controlled entity which provides funding to Caucharí-Olaroz, to reflect the proportionate ownership of Minera Exar. As part of the Transaction, Ganfeng Lithium has agreed to provide US$40 million to Exar Capital in non-interest-bearing loans, repayable in 2029 (subject to an additional one-year

extension). Proceeds of the loan will be used to repay intercompany loans owing to Lithium Americas, with US$20 million to be paid on closing of the Transaction and an additional US$20 million payable on August 1, 2020 (or such earlier date as the parties may agree).

In connection with the Transaction, the parties have agreed to a funding schedule, including investment of up to US$400 million, in accordance with the 2019 approved construction plan. The revised structure of the JV, as set out in the Transaction, is intended to improve Ganfeng Lithium’s financial flexibility and position regarding regulatory approvals in China.

The parties have also agreed to an interim funding structure that could be implemented pending receipt of regulatory approval in order to maintain continuity of project funding, by which Lithium Americas would draw down funds under its loan facilities (the senior credit facility with Ganfeng Lithium and BCP Innovation Pte. Ltd. and subordinated, limited recourse loan facility with Ganfeng Lithium) and with Ganfeng Lithium and on-loan those funds to Minera Exar, with Ganfeng Lithium providing contributions to achieve proportionate share of funding upon securing regulatory approval. In the event that the parties elect to utilize this interim procedure, Lithium Americas would recover all costs of the loan drawdown through interest accruing to its benefit under the loan instruments provided to Minera Exar.

Upon completion of the Transaction, Ganfeng Lithium will become a controlling shareholder of Minera Exar while Lithium Americas will receive fulsome minority shareholder protections. The amended shareholders agreement will continue to require joint approval for substantive business decisions including material changes to:

• Funding plans

• Construction programs

• Project design and process

• Capital and corporate structure

• Production output level

• Capital investment plans (including expansions)

The parties have agreed that Lithium Americas will enter into a management services contract with Ganfeng Lithium which will provide for the continued services of the Company’s senior management, including Gabriel Rubacha as CEO and Franco Mignacco as President of Minera Exar.

Closing of the Transaction is subject to receipt of all required regulatory approvals, consent of Lithium Americas’ senior lenders, settlement of an amended and restated shareholder agreement and other definitive agreements, and other customary closing conditions. The Transaction will terminate if it is not completed by September 30, 2020, unless mutually extended by the parties.

The purpose of the Transaction includes, but is not limited to, advancement of the construction and development of Caucharí-Olaroz, repayment of intercompany loans owing to Lithium Americas, and improving Ganfeng Lithium’s financial flexibility and position regarding regulatory approvals in China.
