1. NATURE OF OPERATIONS

Lithium Americas (Argentina) Corp. (“Lithium Argentina”, the “Company” or “LAAC”), formerly Lithium Americas Corp. (“Lithium Americas” or “LAC”), is a Canadian-based resource company focused on advancing the Cauchari-Olaroz project (“Cauchari-Olaroz”) to full production. Cauchari-Olaroz is a lithium brine project located in the Salar de Olaroz and Salar de Cauchari in Jujuy province, north-western Argentina. The Company also owns the Pastos Grandes lithium project (“Pastos Grandes”) acquired through the acquisition of Millennial Lithium Corp. (“Millennial”) on January 25, 2022, and a 65% ownership interest in the Sal de la Puna project (“Sal de la Puna”), owned by the Company’s wholly-owned subsidiary Arena Minerals Inc. (“Arena Minerals”) acquired on April 20, 2023. Pastos Grandes and Sal de la Puna are lithium brine projects located in Salta province, in north-western Argentina.

The Company’s interest in Cauchari-Olaroz is held through a 44.8% ownership interest in Minera Exar S.A. (“Minera Exar”), a company incorporated under the laws of Argentina. Ganfeng Lithium Co. Ltd. (“Ganfeng”) owns 46.7% of Minera Exar with the remaining 8.5% interest held by Jujuy Energia y Mineria Sociedad del Estado (“JEMSE”), a mining investment company owned by the provincial government of Jujuy. Cauchari-Olaroz is in the commissioning stage and achieved first lithium production as part of commissioning in June 2023.

On March 5, 2024, the Company announced execution of a definitive agreement with a subsidiary of Ganfeng whereby Ganfeng agrees to acquire $70,000 in newly issued shares of Proyecto Pastos Grandes S.A. (“PGCo”) (the “Pastos Grandes Transaction"), the Company’s indirect wholly-owned Argentinian subsidiary holding the Pastos Grandes project in Salta, Argentina, which is expected to represent an approximate 15% interest in PGCo and the Pastos Grandes project. The Pastos Grandes Transaction is subject to applicable regulatory approvals and other closing conditions and is expected to be completed in mid-2024.

On July 31, 2023, at the annual, general and special meeting of the Company, the Company’s shareholders approved the separation of Lithium Americas into Lithium Americas (Argentina) Corp. and a new Lithium Americas Corp. (“Lithium Americas (NewCo)”), pursuant to a statutory plan of arrangement (the “Separation”). The Separation was completed on October 3, 2023, pursuant to a final order dated August 4, 2023, from the Supreme Court of British Columbia approving the plan of arrangement. As a result of the transaction, on October 3, 2023, the Company transferred its North American business, including, among other assets, the Thacker Pass Project (“Thacker Pass”) and $275,499 of cash to Lithium Americas (NewCo), and the Company changed its name to Lithium Americas (Argentina) Corp. (Note 4).

The Company’s common shares are listed on the Toronto Stock Exchange (“TSX”) and the New York Stock Exchange (“NYSE”) under the symbol “LAAC”. The Company’s head office and principal address is Suite 300, 900 West Hastings Street, Vancouver, British Columbia, Canada, V6C 1E5.

To date, the Company has not generated significant revenues from operations and has relied on equity and other financings to fund operations. The underlying values of exploration and evaluation assets are dependent on the existence of economically recoverable reserves, securing and maintaining title and beneficial interest in the properties, and the ability of the Company to obtain the necessary financing to complete permitting and development, and to attain future profitable operations.

2. BASIS OF PREPARATION AND PRESENTATION

These condensed consolidated interim financial statements of the Company (“Interim Financials”) have been prepared in accordance with IFRS Accounting Standards applicable to the preparation of interim financial statements, under International Accounting Standard 34, Interim Financial Reporting. The Interim Financials should be read in conjunction with the Company’s annual consolidated financial statements for the year ended December 31, 2023 (the “2023 Annual Financials”), which have been prepared in accordance with IFRS Accounting Standards.

The Interim Financials are expressed in United State dollars (“US$”), the Company’s presentation currency. The same accounting policies and methods of computation have been used in the Interim Financials and 2023 Annual Financials other than those disclosed in Note 3.

3. SUMMARY OF MATERIAL ACCOUNTING POLICIES

Estimation Uncertainty and Accounting policy judgments

The preparation of these Interim Financials in conformity with IFRS Accounting Standards applicable to the preparation of interim financial statements requires judgments, estimates, and assumptions that affect the amounts reported. Those estimates and assumptions concerning the future may differ from actual results. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The nature and number of significant estimates and judgments made by management in applying the Company’s accounting policies and the key sources of estimation uncertainty are substantially the same as those that management applied to the 2023 Annual Financials.

New IFRS Pronouncements

Amendments to IAS 1 – Presentation of Financial Statements

In October 2022, the IASB issued amendments to IAS 1, Presentation of Financial Statements titled Non-current liabilities with covenants. These amendments sought to improve the information that an entity provides when its right to defer settlement of a liability is subject to compliance with covenants within 12 months after the reporting period. These amendments to IAS 1 override but incorporate the previous amendments, Classification of liabilities as current or non-current, issued in January 2020, which clarified that liabilities are classified as either current or non-current, depending on the rights that exist at the end of the reporting period. Liabilities should be classified as non-current if a company has a substantive right to defer settlement for at least 12 months at the end of the reporting period. The Company adopted these amendments effective January 1, 2024, applied them retrospectively as required by the transitional provisions of the amendments and included restated consolidated statements of financial position for the comparative periods ended December 31, 2023, and January 1, 2023.

Amendments to IAS 1 resulted in a reclassification of equity-settleable convertible notes from non-current liabilities to current liabilities as at January 1, 2023 and December 31, 2023. The convertible notes are convertible at the option of the holders upon satisfaction of certain conditions that are beyond the control of the Company. If such conditions are satisfied, the convertible notes would be convertible at the option of the holders and upon conversion, the convertible notes may be settled, at the Company’s election, in common shares of the Company, cash or a combination thereof. As a result, the Company does not have the right to defer settlement of the convertible notes for more than 12 months after the end of the reporting periods (Note 10).

3. SUMMARY OF MATERIAL ACCOUNTING POLICIES (continued)

IFRS 18 Presentation and Disclosure in Financial Statements

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements which will replace IAS 1, Presentation of Financial Statements. IFRS 18 introduces new requirements on presentation within the statement of profit or loss, including specified totals and subtotals. It also requires disclosure of management-defined performance measures and includes new requirements for aggregation and disaggregation of financial information based on the identified ‘roles’ of the primary financial statements and the notes.

In addition, there are consequential amendments to other accounting standards; some requirements previously included in IAS 1 have been moved to IAS 8 and limited amendments have been made to IAS 7 and IAS 34. IFRS 18 is effective for the reporting period beginning on or after January 1, 2027, with early application permitted. Retrospective application is required in both annual and interim financial statements. The Company has not yet applied this standard, and the application of this standard will have an impact on the presentation of the Company’s financial statement.

4. DISTRIBUTED OPERATIONS

Upon completion of the Separation on October 3, 2023, the Company transferred its North American business, including, among other assets, its Thacker Pass Project and $275,499 of cash to Lithium Americas (NewCo). Pursuant to the plan of arrangement, each shareholder received one common share of Lithium Argentina and one common share of Lithium Americas (NewCo) in exchange for each common share of the Company previously held. The Company has no further interest in Lithium Americas (NewCo) subsequent to the Separation. As part of the approval of the Separation, the Company’s shareholders also approved amendments to the equity incentive plan to allow holders of restricted share units, performance share units and deferred share units to receive on Separation one similar instrument in each of Lithium Argentina (subject to adjustment) and Lithium Americas (NewCo).

The distributed operations have been presented and accounted for using IFRS 5, Non-Current Assets Held for Sales and Discontinued Operations, and IFRIC 17, Distribution of Non-Cash Assets to Owners. Under this guidance, a dividend was recognized in deficit measured at the fair value of the net assets distributed with a corresponding dividend payable. The dividend payable was then settled through the distribution of the net assets. The fair value of the net assets distributed was $1,680,501, determined based on the share price of Lithium Americas (Newco) on October 4, 2023. The difference of $1,267,552 between the fair value of the dividend and the carrying value of the net assets was recognized as a gain on distribution of assets within discontinued operations during the year ended December 31, 2023.

4. DISTRIBUTED OPERATIONS (continued)

The results and cash flows of Lithium Americas (NewCo) presented as discontinued operations are as follows:

5. CASH AND CASH EQUIVALENTS

Cash and cash equivalents

As at March 31, 2024, $1,810 of cash and cash equivalents was held in Canadian dollars (December 31, 2023 – $2,438), $83,684 in US dollars (December 31, 2023 – $119,569) and $705 were held in Argentine Pesos (December 31, 2023 – $286).

6. INVESTMENT IN SAL DE LA PUNA

On April 20, 2023, the Company completed the acquisition of Arena Minerals that owns 65% of Sal de la Puna through a joint venture interest in Sal de la Puna Holdings Ltd., the 100% owner of Argentine entity, Puna Argentina S.A.U. (“PASA”), the owner of the claims forming part of the Sal del la Puna Project.

The remaining 35% of PASA is owned by joint venture partner Ganfeng New Energy Technology Development (Suzhou) Co., Ltd. Therefore, after the acquisition of Arena Minerals, the Company holds a 65% ownership interest in the Sal de la Puna Project covering approximately 13,200 hectares of the Pastos Grandes Basin.

The Company’s 65% ownership interest in Sal de la Puna is considered to be a joint venture and accounted for using the equity method of accounting. Changes in the investment balance are summarized below:

7. INVESTMENT IN CAUCHARI-OLAROZ PROJECT

As at March 31, 2024, the Company, Ganfeng and JEMSE are 44.8%, 46.7% and 8.5% shareholders, respectively, of Minera Exar, the company that holds all rights, title and interest in and to Cauchari-Olaroz, which is located in the Jujuy province of Argentina. The Company and Ganfeng are parties to a shareholders’ agreement concerning management of the project and are entitled to the project’s production offtake on a 49%/51% basis. Construction costs are also shared on the same 49%/51% pro rata basis between the Company and Ganfeng. The shareholders’ agreement regulates key aspects of governance of the project, which provides the Company with significant influence over Minera Exar and strong minority shareholder protective rights.

In addition, the Company and Ganfeng are 49% and 51% shareholders, respectively, in Exar Capital, a company that provides financing to Minera Exar for the purpose of advancing construction of Cauchari-Olaroz (the investment in Minera Exar and investment in Exar Capital together, the “Investment in Cauchari-Olaroz project”). Minera Exar and Exar Capital are accounted for using the equity method of accounting.

Loans to Minera Exar and Exar Capital

The Company has entered into loan agreements with Minera Exar and Exar Capital to fund the construction of Cauchari-Olaroz. Changes in the loans’ balances are summarized below.

7. INVESTMENT IN CAUCHARI-OLAROZ PROJECT (continued)

Loans advanced after January 1, 2022, carry an interest rate of the Secured Overnight Financing Rate (“SOFR”) plus 10.305%.

In Q2 2022, certain of the loans provided by Exar Capital to Minera Exar were amended to introduce a revised repayment mechanism linked to the implied market foreign exchange rate in Argentina. Subsequent to the amendment, the revised repayment feature gives rise to the existence of an embedded derivative in the loans payable by Minera Exar which is required to be measured at fair value at each reporting date. Minera Exar recognized a gain on change in the fair value of the derivative of $17,934 (net of taxes), the Company’s share of which was $8,034 during the three months ended March 31, 2024.

During the three months ended March 31, 2024, loans were provided by the Company to Exar Capital in the amount of $26,925, and by Ganfeng in the amount of $28,024. Such loans funded the Company’s and Ganfeng’s respective 49% and 51% share of Cauchari-Olaroz working capital and other funding requirements.

The maturity of each of the loans is 7 years from the date of drawdown. As at March 31, 2024, loans advanced to Exar Capital by the Company (including accrued interest) of $13,276 are due in Q4 2025, $70,935 are due between 2026 and 2027, $273,801 between 2028 and 2031.

During the three months ended March 31, 2024, Minera Exar obtained debt financing in the form of loans totaling $15,000 from third parties to fund construction and settled approximately $34,000 (a portion of the outstanding third party loans) with a $25,963 loan from Exar Capital. The accumulated amount of such loans obtained from third parties as of March 31, 2024, is approximately $331,000 and they include loans totaling:

As at March 31, 2024, third party loans of approximately $280,000 are due in 2024 (of which $33,000 were settled subsequent to Q1 2024) and $51,000 due in 2025.

Offtake Agreement with Ganfeng and Bangchak

The Company and Ganfeng are entitled to a share of offtake from production at Cauchari-Olaroz. The Company is entitled to 49% of the offtake, which would amount to approximately 19,600 tonnes per annum (“tpa”) of lithium carbonate assuming full capacity is achieved. The Company has entered into an offtake agreement with each of Ganfeng and Bangchak to sell a fixed amount of offtake production at market-based prices, with Ganfeng entitled to 80% of the first 12,250 tpa of lithium carbonate (9,800 tpa assuming full production capacity) and Bangchak entitled to up to 6,000 tpa of lithium carbonate (assuming full production capacity).

7. INVESTMENT IN CAUCHARI-OLAROZ PROJECT (continued)

The balance of the Company’s offtake entitlement, amounting to up to approximately 3,800 tpa of lithium carbonate is uncommitted, but for limited residual rights available to Bangchak to the extent production does not meet full capacity.

Prepayment of purchases and sales of lithium carbonate

In Q2 2023, the Company entered into an agreement to receive prepayments from Ganfeng with respect to the Company’s sale of 80% of its 49% share of the future lithium carbonate production from Minera Exar. The agreement provides the Company the right to settle its obligation to Ganfeng through assigning its rights to receive a corresponding value of lithium carbonate from Minera Exar. Concurrently, the Company entered into an agreement to make prepayments to Minera Exar with respect to the Company’s 49% share of the future lithium carbonate production from Minera Exar.

The prepayments to Minera Exar are non-interest bearing (except in the case of default) and were settled as a credit against the purchase of lithium carbonate within 365 days of the prepayment invoice.

As at January 1, 2024, there were $6,673 prepayments made to Minera Exar and $2,322 prepayments received from Ganfeng, which were fully settled in Q1 2024 against the lithium carbonate purchases from Minera Exar and sales to Ganfeng respectively.

Purchases and sales of lithium carbonate

In Q1 2024, the Company purchased 49% of Minera Exar’s lithium carbonate shipped during the quarter with Ganfeng purchasing the remaining 51% of the product shipped. The Company acted in the capacity of agent in such sales transactions, as the Company’s acquisition of title to lithium carbonate was simultaneous with the sale of lithium carbonate to Ganfeng and Bangchak and the Company was not directly exposed to inventory or price risk related to lithium carbonate.

Since there was no net amount of commission to the Company, there was no impact on the Company’s statement of comprehensive loss for the three months ended March 31, 2024.

As at March 31, 2024, the Company has $5,448 payable to Minera Exar and $9,009 receivable from Ganfeng included in payable to Minera Exar for lithium carbonate purchases and receivables from purchasers of lithium carbonate on the statement of financial position respectively.

7. INVESTMENT IN CAUCHARI-OLAROZ PROJECT (continued)

Investment in Cauchari-Olaroz Project

Changes in the Investment in Cauchari-Olaroz Project are summarized below:

During the three months ended March 31, 2024, the Company’s share of Minera Exar loss was $1 and contributions to the investment in Minera Exar were $428. The Company’s share of Exar Capital loss was $1,128 for the three months ended March 31, 2024.

Minera Exar’s Commitments and Contingencies

As at March 31, 2024, Minera Exar had the following commitments (on a 100% basis):

8. PROPERTY, PLANT AND EQUIPMENT

1 The “Other” category includes right of use assets with a cost of $1,911 and $1,265 of accumulated depreciation as at March 31, 2024.

9. EXPLORATION AND EVALUATION ASSETS

Exploration and evaluation assets were as follows:

The Company has certain commitments for royalty and other payments to be made for Pastos Grandes as set out below. These amounts will only be payable if the Company continues to hold the subject claims in the future and the royalties will only be incurred if the Company starts production from the project.

Pastos Grandes:

10. EQUITY-SETTLEABLE CONVERTIBLE NOTES

On December 6, 2021, the Company closed an offering (the “Offering”) of $225,000 aggregate principal amount of 1.75% convertible senior notes due in 2027 (the “Convertible Notes” or “Notes”). The Company used a portion of the net proceeds from the Offering to repay in full its $205,000 senior secured credit facility. On December 9, 2021, the initial purchasers under the Offering exercised in full their option to purchase up to an additional $33,750 aggregate principal amount of the Convertible Notes, increasing the total Offering size to $258,750.

The Convertible Notes represent financial instruments that include a debt host accounted for at amortized cost and conversion option and redemption option derivatives, which are separated from the debt host and accounted for at fair value with changes in fair value recorded in the statement of comprehensive loss. These derivatives are accounted for together as a single derivative when separated from the debt host.

10. EQUITY-SETTLEABLE CONVERTIBLE NOTES (continued)

The fair value of the derivative as at March 31, 2024, is estimated using a partial differential equation method with Monte Carlo simulation with the following inputs: volatility of 64.21%, share price of $5.39, a risk-free rate of 4.44%, an expected dividend of 0%, and a credit spread of 8.08%. Valuation of the embedded derivative is highly sensitive to changes in the Company’s share price and to a lesser extent to changes in the risk-free interest rate and the assumed volatility of the Company’s share price. A gain on change in fair value for the three months ended March 31, 2024, of $4,743 was recognized in the statement of comprehensive loss.

The Company paid interest of $2,264 during the three months ended March 31, 2024 due under its Convertible Notes. Interest expense for the three months ended March 31, 2024 of $5,996 was recognized as finance costs in the statement of comprehensive loss.

Amendments to IAS 1 resulted in a reclassification of equity-settleable convertible notes from non-current liabilities to current liabilities as at January 1, 2023 and December 31, 2023 (Note 3). The Convertible Notes are convertible at the option of the holders upon satisfaction of certain conditions that are beyond the control of the Company. If such conditions are satisfied, the Convertible Notes would be convertible at the option of the holders and upon conversion, the Notes may be settled, at the Company’s election, in common shares of the Company, cash or a combination thereof. As a result, the Company does not have the right to defer settlement of the Convertible Notes for more than 12 months after the end of the reporting periods.

The Convertible Notes are unsecured and accrue interest payable semi-annually in arrears at a rate of 1.75% per annum payable on January 15th and July 15th of each year, beginning on July 15, 2022. Prior to October 15, 2026, the Notes are convertible at the option of the holders during certain periods, upon the satisfaction of certain conditions including:

10. EQUITY-SETTLEABLE CONVERTIBLE NOTES (continued)

Thereafter, the Convertible Notes will be convertible at any time until the close of business on the business day immediately preceding the maturity date. Upon conversion, the Convertible Notes may be settled, at the Company’s election, in common shares of the Company, cash or a combination thereof. The Conversion Rate for the Convertible Notes was adjusted on October 17, 2023, to 52.6019 common shares of the Company per $1,000 principal amount of the Convertible Notes.

The Convertible Notes mature on January 15, 2027, unless earlier repurchased, redeemed or converted. The Company may not redeem the Convertible Notes prior to December 6, 2024, except upon the occurrence of certain changes to the laws governing Canadian withholding taxes. After December 6, 2024, the Company has the right to redeem the Convertible Notes at its option in certain circumstances including:

Redemption can result in exercisability of the conversion option. Holders of Convertible Notes have the right to require the Company to repurchase their Convertible Notes upon the occurrence of certain events.

11. SHARE CAPITAL AND EQUITY COMPENSATION

Share Capital

On April 20, 2023, the Company closed the acquisition of 100% of Arena Minerals and issued 8,456 shares to Arena Minerals shareholders.

On February 16, 2023, the Company issued 15,002 common shares as part of the closing of the first tranche of General Motor’s investment.

Equity Incentive Plan

The Company has an equity incentive plan (“Plan”) in accordance with the policies of the TSX whereby, from time to time at the discretion of the Board of Directors, eligible directors, officers, employees and consultants are awarded restricted share units (“RSUs”) and performance share units (“PSUs”) that, subject to a recipient’s deferral right in accordance with the Income Tax Act (Canada), convert automatically into common shares upon vesting. In addition, independent directors are awarded deferred share units (“DSUs”), generally as partial compensation for their services as directors. DSUs may be redeemed by directors for common shares upon retirement or termination from the Board. The Plan also permits the grant of incentive stock options exercisable to purchase common shares of the Company (“stock options”). The Plan is a “fixed plan” pursuant to which the aggregate number of common shares to be issued shall not exceed 14,401 shares.

Restricted Share Units

During the three months ended March 31, 2024, the Company did not grant any RSUs (2023 – 252) to its employees and consultants. The total estimated fair value of the RSUs granted during the three months ended March 31, 2023, was $6,368 based on the market value of the Company’s shares on the grant date. As at March 31, 2024, there was $4,149 (2023 – $4,627) of total unamortized compensation cost relating to unvested RSUs. During the three months ended March 31, 2024, equity compensation expense related to RSUs of $429 was charged to expenses (2023 – $204). Subsequent to March 31, 2024, 473 RSUs were issued for 2023 annual bonuses which are subject to the shareholders’ approval.

A summary of changes to the number of outstanding RSUs is as follows:
