NATURE OF OPERATIONS

Lithium Argentina AG (“Lithium Argentina”, the “Company” or “LAR”), formerly Lithium Americas (Argentina) Corp., is a Swiss- domiciled resource company with lithium projects located in Argentina.

On January 23, 2025, the Company completed a plan of arrangement under the laws of the province of British Columbia (the “Arrangement”) involving the Company’s continuation from the province of British Columbia under the name “Lithium Americas (Argentina) Corp.” into Zug, Canton of Zug, Switzerland, as a Swiss share corporation under the name “Lithium Argentina AG.” As a result, the Company ceased to be governed by the Business Corporations Act (British Columbia). Following the Arrangement, the shareholders of the Company prior to the Arrangement continued to hold all the issued and outstanding common registered shares of the Company (the “Continuation”) (Note 13). On January 27, 2025, the Company began trading under the new symbol “LAR” on the Toronto Stock Exchange (“TSX”) and the New York Stock Exchange (“NYSE”).

The Company is focused on the operations of the Cauchari-Olaroz project (“Cauchari-Olaroz”). Cauchari-Olaroz is a lithium brine operation located in the Salar de Olaroz and Salar de Cauchari in Jujuy province, 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 production stage and achieved commercial production effective October 1, 2024, and is accounted for using the equity method.

The Company also owns 85.1% interest in 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”), held by the Company’s wholly-owned subsidiary Arena Minerals Inc. (“Arena Minerals”) which was acquired on April 20, 2023. Pastos Grandes and Sal de la Puna are lithium brine projects located in Salta province, in north-western Argentina. Pastos Grandes is fully consolidated in the Company’s financial statements, whereas Sal de la Puna is accounted for using the equity method.

The Company's registered office is located at Dammstrasse 19, 6300 Zug, Switzerland.

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 and were approved by the Board of Directors on November 7, 2025. The Interim Financials should be read in conjunction with the Company’s annual consolidated financial statements for the year ended December 31, 2024 (the “2024 Annual Financials”), which have been prepared in accordance with IFRS Accounting Standards.

The Interim Financials are expressed in United States dollars (“US$”), the Company’s presentation currency. The same accounting policies and methods of computation have been used in the Interim Financials and 2024 Annual Financials other than those disclosed in Note 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 the same as those that management applied to the 2024 Annual Financials except as disclosed below.

New IFRS Pronouncements

IFRS 18 Presentation and Disclosure in Financial Statements

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 is currently assessing the impact of this standard on its financial statements and has not yet applied it.

Amendments to IFRS 9 and IFRS 7 – Amendments to the Classification and Measurement of Financials Instruments

In May 2024, the IASB issued amendments to IFRS 9 and IFRS 7, Amendments to the Classification and Measurement of Financial Instruments. These amendments updated classification and measurement requirements in IFRS 9 Financial Instruments and related disclosure requirements in IFRS 7 Financial Instruments: Disclosures. The IASB clarified the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they meet the solely payments of principal and interest criterion, including financial assets that have environmental, social and corporate governance (ESG)-linked features and other similar contingent features. These amendments require additional disclosures for financial instruments with contingent features that do not relate directly to basic lending risks and costs and amended disclosures relating to equity instruments designated at fair value through other comprehensive income.

SUMMARY OF MATERIAL ACCOUNTING POLICIES (continued)

The amendments are effective for annual periods beginning on or after January 1, 2026. Early adoption is permitted, with an option to early adopt the amendments for contingent features only. The Company is currently assessing the impact of these amendments on its financial statements and has not yet applied it.

SAL DE LA PUNA JOINT VENTURE

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 13,852 hectares of the Pastos Grandes Basin.

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

INVESTMENT IN CAUCHARI-OLAROZ PROJECT

As at September 30, 2025, the Company, Ganfeng, and JEMSE hold 44.8%, 46.7%, and 8.5% equity interests, respectively, in Minera Exar, the company that holds all rights, title, and interest in the Cauchari-Olaroz project, located in the Jujuy province of Argentina.

JEMSE acquired its 8.5% equity interest in Minera Exar in April 2021, which was divided as 4.2% from the Company and 4.3% from Ganfeng. The right to acquire this 8.5% interest was initially granted under a letter of intent signed in 2012, in compliance with the Province of Jujuy's regulations concerning government participation in mineral projects. As part of the closing of the JEMSE transaction in April 2021, JEMSE agreed to reimburse the Company and Ganfeng their pro-rata share of $23,496 (8.5%) for the equity financing provided for the construction of the Cauchari-Olaroz project in prior years. This amount reflected the reimbursement obligation as measured at the initial transaction date, subsequent changes in the expected recoverable amount of this receivable were recognized during the three months ended September 30, 2025, as described below. This reimbursement will be made through the assignment of one-third of the dividends otherwise payable to JEMSE in future periods. Annual dividend distributions by Minera Exar to all shareholders, including JEMSE, will only be considered once Minera Exar has met all project debt commitments for the Cauchari-Olaroz project.

The Company’s operations related to Cauchari-Olaroz are conducted through its equity investees, Minera Exar and Exar Capital, which are governed by a shareholders’ agreement between the Company and Ganfeng. The shareholders’ agreement regulates key aspects of the governance of the project and provides the Company with significant influence over Minera Exar. Under this agreement, the Company and Ganfeng are entitled to the project’s production offtake on a 49%/51% basis. Construction costs were also shared on the same 49%/51% pro rata basis between the Company and Ganfeng.

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

During the nine months ended September 30, 2025, as part of a restructuring of loans (the “Restructuring”), the Company and Ganfeng amended and restated loan agreements relating to loans advanced to Exar Capital. Concurrently, Exar Capital amended and restated agreements relating to the loans advanced to Minera Exar (collectively, the “Amendments”), revising interest rates to market levels effective for fiscal year 2025 and subsequent periods and extending the maturity dates. These modifications were treated as an extinguishment of the existing loans and the issuance of new loans at market rates of interest.

As part of the Restructuring, on August 27, 2025, Exar Capital assigned certain loan receivables from Minera Exar to the Company and Ganfeng. The total carrying value of the loans assigned was $208,121, with the Company’s portion amounting to $101,979. In exchange, the Company cancelled loans owed by Exar Capital with carrying value of $99,422. The assigned loans receivable from Minera Exar were subsequently settled through a capital contribution by the Company and Ganfeng to Minera Exar. The difference was recognized as an increase in the Company’s investment in the Cauchari-Olaroz project, reflecting the equity nature of the transaction between shareholders.

Because the Restructuring resulted from transactions between shareholders rather than with external parties, the Company determined that the net effect represented a transaction between owners in their capacity as owners.

(Expressed in thousands of US dollars, except for per share amounts; shares and equity instruments in thousands)

INVESTMENT IN CAUCHARI-OLAROZ PROJECT (continued)

Accordingly, the capitalization of loans was recorded as an increase in the Company’s investment in the Cauchari-Olaroz project, with no gain or loss recognized in the statement of comprehensive loss.

In connection with the Restructuring, JEMSE retained its ownership interest in Minera Exar in exchange for an agreement to reimburse the Company and Ganfeng through the assignment of one-third of dividends otherwise payable to JEMSE in future periods, up to an additional $8,271 and $8,609, respectively. This reimbursement will occur after the previous dividend assignment has been fully repaid.

Prior to the Restructuring, the Company recorded an adjustment to the carrying value of the previous JEMSE receivable based on revised cash flow estimates, and recognized a corresponding loss of $3,382, presented as “Loss on JEMSE receivable” in the statement of comprehensive loss.

The Company recognized its portion of the additional JEMSE receivable at fair value of $2,789 and recorded a reduction in its investment of $8,668, resulting in a loss of $5,879, included in “Loss on JEMSE receivable”. As at September 30, 2025, the carrying value of the two long-term receivables from JEMSE was $7,885 (2024 – $7,935).

For the nine months ended September 30, 2025, the Company recognized its share of losses from the Cauchari-Olaroz project totaling $53,422 in the statement of comprehensive loss. This amount includes current year losses of $27,379 and previously unrecognized losses of $26,043 from 2024, which were recognized following the capitalization of loans to Minera Exar that increased the carrying amount of the Company’s investment.

As of October 1, 2024, Minera Exar determined that commercial production had been achieved for the Cauchari-Olaroz project after reaching elevated production levels for a sustained period. As a result, the Cauchari-Olaroz project’s assets were considered ready for their intended use, and depreciation of these assets commenced on October 1, 2024.

The following is the condensed financial information of Minera Exar on a 100% basis, as amended to reflect the Company’s accounting policies.

As of September 30, 2025, Minera Exar’s outstanding third-party debt amounted to $285,122 (2024 – $210,400), while its cash balance was $53,685 (2024 – $11,190). The total debt includes the following:

Approximately $220,000 in loans from major international banks, secured by guarantees and standby letters of credit arranged by Ganfeng, which are due within twelve months from September 30, 2025. The Company has provided a guarantee to Ganfeng for its 49% share, amounting to $107,800, in respect of these loans. The Company and Ganfeng have negotiated a three-year extension of the maturity of $100,000 of these loans, which has been approved by the regulatory authority and is in the process of implementation. Included within these loans is $120,000 in bank debt facilities closed in the second quarter of 2025 and fully drawn in the third quarter of 2025 to refinance maturing short-term loans and for other purposes. These loans were competitively priced at an approximately SOFR plus 2.5%, including fees, reflecting Exar’s ability to access credit on favorable terms. A portion of these debt proceeds remained in Exar’s cash balance as of September 30, 2025.
$10,000 in loans secured by local bank guarantees arranged by Minera Exar, due in 2025.
Approximately $50,000 in unsecured bonds issued by Minera Exar in November 2024, carrying a contractual interest rate of 8% with semi-annual interest payments. The bonds’ principal will mature in two tranches: the first tranche of $25,000 on May 11, 2027, while the second tranche of $25,000 on November 11, 2027.

In October 2025, Exar acquired $30,000 of promissory notes issued by Litio Minera Argentina S.A., a wholly owned subsidiary of Ganfeng, to optimize the return on Exar’s temporary excess liquidity. The notes mature on December 15, 2025.

All values are in US Dollars.

Minera Exar has to settle certain loans provided by Exar Capital and PGCo in US$ with sufficient Argentine Pesos (“ARS$”) at the implied market exchange rate. This settlement mechanism requires Minera Exar to repay the loans with more US$ at the official exchange rate. Since the repayment mechanism for the USD loans provided by Exar Capital and PGCo to Minera Exar is linked to the implied market foreign exchange rate in Argentina rather than the official foreign exchange rate, it results in an embedded derivative in the loans payable by Minera Exar. The fair value of this embedded derivative fluctuates with changes in the spread between the implied market exchange rate and the official exchange rate). During the nine months ended September 30, 2025, changes in Argentine foreign exchange regulations caused the implied exchange rate to converge with the official rate, resulting in a fair value gain of $51,288, which was recognized within other (loss)/income in Minera Exar’s condensed statement of comprehensive (loss)/income.

During the period, other loss in Minera Exar’s condensed statement of comprehensive (loss)/income primarily comprises of interest expense and other costs related to intercompany and third-party borrowings and selling, distribution, and administrative expenses, partially offset by the gain on change in fair value of the embedded derivative described above.

Under the amended and restated loan agreements, the loans advanced by the Company to Exar Capital bear interest rates ranging from 8.12% to 8.95%. As part of the amendment, the maturities of the loans were extended, with revised maturity dates ranging from 2028 to 2035.

As of September 30, 2025, the total outstanding loans to Exar Capital, including accrued interest, amounted to $301,958 of which $18,845 due in 2028, $23,126 due in 2029, $27,697 due in 2030, $27,794 due in 2031, $36,539 due in 2032, $46,721 due in 2033, $39,071 due in 2034, and $82,166 due in 2025.

The recoverability of these loans is dependent on the future cash flows and performance of the Cauchari-Olaroz project. The Company performed an expected credit loss assessment based on the anticipated future performance and cash flow projections of Cauchari-Olaroz. The assessment did not identify any significant increase in credit risk or other factors that would indicate a potential default.

PURCHASES AND SALES OF LITHIUM CARBONATE

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 BCP Innovation PTE. LTD (“Bangchak”), a wholly-owned subsidiary of Bangchak Corporation Public Company Ltd., 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).

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.

Purchases and sales of lithium carbonate

During the nine months ended September 30, 2025, the Company purchased its 49% share of Minera Exar’s lithium carbonate shipped during the period. The Company sold the purchased lithium carbonate to Ganfeng and Bangchak and 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.

During the nine months ended September 30, 2025, the Company made approximately $88,985 worth of purchases of lithium carbonate from Minera Exar and sold an equivalent amount, totaling approximately $88,985, to Ganfeng and Bangchak. Since there was no net commission earned by the Company, there was no impact on the Company’s statement of comprehensive loss for nine months ended September 30, 2025.

PURCHASES AND SALES OF LITHIUM CARBONATE (continued)

As at September 30, 2025, the Company had a payable of $19,463 to Minera Exar for lithium carbonate purchases, and receivables totaling $19,463 from Ganfeng for sales of lithium carbonate, as disclosed on the statement of financial position. The Company performed an expected credit loss assessment for these receivables, which did not indicate any significant credit risk or factors that would result in default, as the majority of the receivables were settled after September 30, 2025.

PASTOS GRANDES

On August 16, 2024, Proyecto Pastos Grandes S.A. (“PGCo”), a wholly-owned subsidiary of the Company holding the Pastos Grandes project in Salta, Argentina, issued common shares representing approximately 14.9% of PGCo to Ganfeng for a consideration of approximately $70,000 (the “Pastos Grandes transaction”).

As the Company retained control of PGCo, the transaction was accounted for as an equity transaction, resulting in the recognition of a non-controlling interest representing Ganfeng Lithium’s 14.9% share in the net assets of PGCo.

In Q3 2024, PGCo utilized the proceeds from the Pastos Grandes transaction to enter into $65,000 loan facility agreement with Minera Exar to fund its debt repayment, working capital and other requirements. The loan matures in five years and carries an interest rate of SOFR plus 4.0% (Note 22).

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 Notes due in 2027 (the “Convertible Notes”, “Notes”, or “equity-settleable convertible notes”). 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.

The fair value of the derivative as at September 30, 2025, was estimated using a partial differential equation method with Monte Carlo simulation with the following inputs: volatility of 68.00%, share price of $3.34, a risk-free rate of 3.66%, an expected dividend of 0%, and a credit spread of 7.50%. 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 nine months ended September 30, 2025, of $111 (2024 – $11,046) was recognized in the consolidated statement of comprehensive loss. Interest expense for the nine months ended September 30, 2025, of $20,528 (2024 – $18,556) was recognized as finance costs in the consolidated statement of comprehensive loss.

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 and presents the Convertible Notes within its current liabilities.

EQUITY-SETTLEABLE CONVERTIBLE NOTES (continued)

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:

If the Notes’ trading price for any five consecutive trading day period was, on each day, less than 98% of the conversion value of such Notes;
if the Company elects to (a) issue equity instruments to all holders of the Company’s common shares entitling them, for a period of not more than 45 calendar days after issue, to subscribe for or purchase common shares at a price per share that is less than the average reported sales prices of the common shares for the 10-trading day period ending the trading day before the announcement of such issuance of equity instruments; or (b) make a distribution to all holders of the Company’s common shares, whether such distribution is of assets, securities, or rights to purchase the Company’s securities, and has a per share value exceeding at least 10% of the trading price of the common shares on the date immediately preceding the announcement date of such distribution;
upon the occurrence of certain significant business events;
if, at any time after the calendar quarter ending on March 31, 2022 (and only during such calendar quarter), the last reported price of the Company’s common shares for at least 20 trading days (whether or not consecutive) during the last period of 30 trading days of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day (this has not occurred during the nine months ended September 30, 2025); or,
upon a call for redemption by the Company, or upon the Company’s failure to pay the redemption price therefor.

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 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:

on or after December 6, 2024, if the Company’s share price for at least 20 trading days during any 30 consecutive trading day period ending on, and including, the last trading day of the immediately preceding calendar quarter is over 130% of the conversion price on each applicable trading day, at a redemption price equal to 100% of the principal plus accrued and unpaid interest; and
if the Company becomes obligated to pay additional amounts as a result of its obligation to bear the cost of Canadian or non-Canadian withholding tax, if applicable.

EQUITY-SETTLEABLE CONVERTIBLE NOTES (continued)

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.

The Conversion Rate (as defined in the Indenture) for the Convertible Notes was initially 21.2307 common shares per $1,000 principal amount of the Convertible Notes. Pursuant to the terms and conditions of the Indenture, 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 based on the trading prices of the Company’s common shares over the preceding 10-trading day period due to the Separation transaction. The Conversion Rate for the Convertible Notes was not adjusted as a result of the Continuation. None of the Convertible Notes were surrendered for conversion during the permitted conversion period in connection with the Continuation.

SHARE CAPITAL AND EQUITY COMPENSATION

On January 23, 2025, the Company completed the Continuation from Canada to Switzerland. As a result of the Continuation, Lithium Argentina's shares were established with a nominal par value of $0.01 per share. The number of shares outstanding remained unchanged. The components of shareholders’ equity have been retrospectively adjusted to reflect the Swiss capital structure in all periods presented.

The share capital is fully paid-in, meaning that the entire issue price of the shares has been fully paid to Lithium Argentina. Lithium Argentina has one class of shares outstanding, being the Common Shares. The Common Shares are not convertible into shares of any other class or series.

Equity Incentive Plan

The Company has an equity incentive plan (the “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 “rolling plan” pursuant to which the aggregate number of common shares to be issued shall not exceed 8% of the outstanding shares from time to time.

Restricted Share Units

During the nine months ended September 30, 2025, the Company granted 4,529 RSUs (2024 – 1,883) to its employees and consultants.

INCOME TAXES

In January 2025, the Company completed its corporate continuation from Canada to Switzerland. As a result, the corporate headquarters is now subject to Swiss taxation, and the Canadian tax losses and other Canadian tax attributes are no longer available to offset future taxable income at the corporate level. The Company continues to be subject to income taxes in other jurisdictions, including Canada, Argentina, and the Netherlands, through its subsidiaries.

Following the Continuation, the Company remeasured the tax basis of its corporate level assets and liabilities under Swiss tax rules. This remeasurement gave rise to certain temporary differences, and a deferred tax liability of $1,827 was recognized earlier in the year. During the three months ended September 30, 2025, the Company reassessed its deferred tax position and concluded that the temporary differences recognized upon Continuation were no longer applicable under current tax circumstances. As a result, the previously recognized deferred tax liability of $1,827 was derecognized, generating a deferred tax recovery of $1,827 for the quarter.

No deferred tax liability is recorded on the consolidated statement of financial position as of September 30, 2025.

FINANCIAL INSTRUMENTS

Financial instruments recorded at fair value on the consolidated statements of financial position and presented in fair value disclosures are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy has the following levels:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2 – Inputs other than quoted prices that are observable for assets or liabilities, either directly or indirectly; and

Level 3 – Inputs for assets and liabilities that are not based on observable market data.

The Convertible Notes derivatives (Note 12) are classified at level 2 of the fair value hierarchy and are measured at fair value on the statement of financial position on a recurring basis. Cash and cash equivalents, receivables and payable associated with lithium carbonate sales and purchases, other receivables/payables, and the debt host of the Convertible Notes are measured at amortized cost on the statement of financial position. As at September 30, 2025, the fair value of financial instruments measured at amortized cost approximates their carrying value.

The Company manages risks to minimize potential losses. The primary objective of the Company’s risk management process is to ensure that the risks are properly identified and monitored, and that the capital base maintained by the Company is adequate in relation to those risks. The principal risks impacting the Company’s financial instruments are described below.

Credit Risk

Credit risk is the risk of loss associated with a counterparty’s inability to fulfill its payment obligations. Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents, receivables from Ganfeng for purchases of lithium carbonate, long-term receivable from JEMSE, and receivables related to loans advanced to Exar Capital and Minera Exar (refer Note 6, 7, 8 and 9).

The Company’s maximum exposure to credit risk for cash, cash equivalents, receivables, long-term receivable from JEMSE, and loans to Exar Capital and Minera Exar is the amount disclosed in the condensed consolidated statements of financial position. The Company limits its exposure to credit loss on cash and cash equivalents by placing its cash and cash equivalents with two major financial institutions and investing in only short-term obligations, with expected credit losses on cash and cash equivalents estimated to be de minimis. As of September 30, 2025, the Company holds a significant portion of its cash and cash equivalents with a single financial institution. This concentration exposes the Company to credit risk in the event that the financial institution encounters liquidity or credit issues.

The Company has assessed the creditworthiness of this institution and believes that the risk of default is minimal, given its credit rating. However, the Company intends to further mitigate this risk by diversifying its cash holdings to additional financial institutions subsequent to September 30, 2025. This strategy is designed to reduce concentration risk and enhance overall liquidity management.

(Expressed in thousands of US dollars, except for per share amounts; shares and equity instruments in thousands)

FINANCIAL INSTRUMENTS (continued)

The Company actively monitors credit exposure to Minera Exar and Exar Capital, which are related parties involved in the Cauchari-Olaroz Project. Management reviews their financial position regularly and, given the strategic nature of these relationships and the support from project partners, ensures that credit risk on these balances is maintained at acceptable levels.

The Company and its subsidiaries and investees, including Minera Exar, may from time to time make short-term investments in Argentine government securities, financial instruments guaranteed by Argentine banks, and other Argentine securities. These investments may or may not result in short-term gains or losses.

The Central Bank of Argentina maintains certain currency controls that limit the Company's ability to remit cash to and from Argentina. Blue chip swaps are trade transactions that effectively allow companies to transfer US dollars into and out of Argentina at market exchange rates. The Company used this mechanism to transfer funds to Argentina, which resulted in foreign exchange gain due to the divergence between the Blue Chip Swap market exchange rate and the official Argentine Central Bank rate.

Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company’s approach to managing liquidity is to evaluate current and expected liquidity requirements under both normal and stressed conditions, in order to estimate and maintain sufficient reserves of cash and cash equivalents to meet its liquidity requirements in both the short and long-term. The Company prepares annual budgets, which are regularly monitored and updated as considered necessary.

As at September 30, 2025, the Company had $75,000 available under its undrawn limited recourse loan facility with Ganfeng. As at September 30, 2025, the Company had a cash and cash equivalents balance of $63,998 and receivables from purchasers for lithium carbonate of $19,463 to settle current liabilities of $25,124 (excluding equity-settleable convertible notes).

The following table summarizes the contractual maturities of the Company’s financial liabilities on an undiscounted basis:

The Convertible Notes were classified as current liabilities as at September 30, 2025, since the 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 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 (Note 12). The above table summarizes the contractual maturities as at September 30, 2025, with respect to the Convertible Notes assuming such conditions will not be satisfied before the due date.

FINANCIAL INSTRUMENTS (continued)

Market Risk

Market risk encompasses a range of risks. Movement in risk factors, such as market price risk, the Company’s share price, and currency risk, can affect the fair values of financial assets and liabilities. The Company is exposed to foreign currency risk, as described below.

Foreign Currency Risk

The Company’s operations in foreign countries are subject to currency fluctuations, which may affect its financial results.

The Company and its subsidiaries and associates have a US dollar functional currency, and it incurs expenditures in Canadian dollars (“CDN$”), Argentine Pesos (“ARS$”), Swiss francs (“CHF”) and US$, with the majority of the expenditures being incurred in US$ by the Company’s subsidiaries and investees. As at September 30, 2025, the Company did not hold significant amounts of cash and cash equivalents denominated in CDN$, ARS$, and CHF.

SUBSEQUENT EVENT

In October 2025, Minera Exar and PGCo amended the existing $65,000 loan facility agreement between the parties (Note 9). The amendment revised the interest rate to 6.18%. The revised rate is effective for fiscal year 2025 and subsequent periods.

During the third quarter of 2025, production at Cauchari-Olaroz reached approximately 8,300 tonnes. The operation prioritized stability and reliability of production, focusing on consistent output while implementing improvements designed to enhance long-term efficiency to better position the operation in the future. The production volumes for the first nine months of the year reached approximately 24,000 tonnes, keeping the operation on track to achieve the full-year production guidance of 30,000 to 35,000 tonnes.

The cost of sales for the third quarter of 2025 was $57 million, with cash operating costs of $6,285 per tonne5 of lithium carbonate sold. For the nine months ended September 30, 2025, cash operating costs totaled about $6,322. Q3 costs were consistent with the year-to-date average and slightly higher than the prior quarter due to planned maintenance, recognition of deferred maintenance costs, and higher reagent use from ongoing optimization programs.

PPG Project

Ganfeng and Lithium Argentina have entered into a framework agreement with respect to the New JV6 to develop PPG. The New JV will be modeled on the Cauchari-Olaroz joint venture including proportional ownership and funding, shared governance with clear decision rights, and pro-rata offtake allocation. Under the contemplated structure, Ganfeng will act as the lead technical partner and operator, incorporating its technical expertise for Direct Lithium Extraction (“DLE”) (as defined herein) and downstream processing, while Lithium Argentina will provide its strong upstream and local knowledge and bring expertise to support the permitting, in-country execution, and stakeholder engagement. Definitive agreements are being finalized, subject to customary board and regulatory approvals. Upon closing, the New JV will be structured with Ganfeng holding 67% and Lithium Argentina 33% of PPG, with ownership based on resources, capital contributions and technology inputs.

Results for a Scoping Study (“Scoping Study”) for PPG outline a phased development with initial 50,000 tpa of LCE increasing to 150,000 tpa using a hybrid DLE flowsheet that pre-concentrates brine in ponds, then selectively recovers lithium from concentrated brine before final purification and production of lithium carbonate. The technical approach aims to lower reagent and environmental intensity versus traditional processes and is expected to improve product consistency and quality, while reducing costs at a large production scale.

The Secretariat of Mining and Energy of the Province of Salta, Argentina, issued the Environmental Impact Statement, Declaración de Impacto Ambiental, (“DIA”) for Stage 1 of the PPG Project, closing a 14-month review of the project and the technology.

The PPG Project preserves product-path flexibility, allowing built-in product optionality to tailor the final lithium product to meet offtake specifications and market conditions. Development will be executed stage by stage, leveraging existing on-site infrastructure and sequencing permits, community engagement, and financing ahead of major commitments.

The partners will jointly pursue financing options, including collaboration with potential partners and strategic partners for offtake and minority ownership interests.

RIGI Related Benefits

Argentina’s Régimen de Incentivo para Grandes Inversiones (RIGI) is a government framework designed to attract large-scale investment by providing stable, long-term tax, regulatory and foreign exchange benefits. PPG will seek access to Argentina’s RIGI framework to enhance long-term competitiveness and support ongoing financing efforts. Opting into this regime is subject to securing RIGI eligibility and approvals and is expected to materially improve after-tax cash flow through a series of fiscal incentives, including but not limited to (1) a 25% corporate income tax rate (vs. 35% general regime), (2) export-duty relief (exemption after a qualifying period and minimum investment), and (3) accelerated tax depreciation (e.g. equipment over ~2 years; plant/property at ~1.6x the usual rate). In aggregate, these features are assumed in the base case model and lift post-tax NPV by $0.9 billion, with an IRR improving by 7.6%. The Company’s eligibility for benefits under the RIGI program remains subject to approval.

Capital Costs

The capital cost for life of project at PPG is estimated at $3.3 billion, inclusive of a 16% contingency, based on construction and are based on Argentine costs for labor and materials. This reflects a total capital intensity of approximately $21,900 per tonne of annual LCE production.

Capital Cost – Life of Project	($ millions)
Total Direct Costs (including contingency)
Wellfield, Ponds and Brine Systems	$1,318

Sub-Total	$3,125
Total Indirect Costs
Owner Costs	$91
VAT	$85
Total Capital Costs (including contingency)	$3,301

The capital costs for Stage 1 development at PPG is estimated at $1.1 billion, inclusive of a 16% contingency based on construction and are based on Argentine costs for labor and materials. This reflects a total capital intensity of approximately $22,000 per tonne of annual LCE production.

Capital Cost – Stage 1	($ millions)
Total Direct Costs (including contingency)
Wellfield, Ponds and Brine Systems	$337

Infrastructure/Power/TMA Costs	$248
Sub-Total	$1,045
Total Indirect Costs
Owner Costs	$32
VAT	$47
Total Capital Costs (including contingency)	$1,124

The Scoping Study contemplates a staged development underpinned by both existing site infrastructure and new process facilities. Wellfields, ponds and brine system infrastructure are largely related to the construction of these items. Plants’ capital costs include all the capital for the lithium plant, including: DLE plant, purification plant, utilities and LCE processing facilities.

Infrastructure, Power/Tailing Management Area (“TMA”) and energy costs relate to water supply, transformers, warehouse office buildings, camps, effluent plant, and waste yard infrastructure, power lines, fuel plant and emergency generation and salts disposal costs.

The sustaining capital requirement for the life of project is estimated at an average of approximately $324 per tonne of LCE produced.

PPG Project Valuation Price Sensitivities and Returns

The financial results are derived from inputs based on an annual production schedule included in the Scoping Study. The PPG Scoping Study estimates strong returns with incremental after-tax NPV10% of $5.8 billion and NPV8% of $8.1 billion.

Next Steps

With the receipt of the environmental permit application, the RIGI application is expected during the first half of 2026. The Company and Ganfeng are exploring financing options including debt offtake and minority equity investments to support funding for Stage 1 of PPG.

Ganfeng and Lithium Argentina continue to advance optimization efforts and integration of the resources into a unified hydrological model. The results of the integration and optimization efforts will support further technical information used to support Stage 1 development.

Non-IFRS Measures

All-in sustaining cost per tonne and operating cash costs per tonne are non-IFRS measures or ratios and do not have a standardized meaning under IFRS and may not be comparable to similar financial measures used by other issuers. The Company believes that this measure provides investors with an improved ability to evaluate the prospects of the Company and the PPG Project. As the PPG Project is not in production, all-in sustaining cost and operating cash cost may not be reconciled to the nearest comparable measures under IFRS and the equivalent historical non-IFRS measure discussed herein is $nil.

Operating Cash Cost	$ per tonne of LCE
Projected Operating Cash Cost – Stage 1	$5,344

Environmental and Social Responsibility

In September 2025, Cauchari-Olaroz held a monitoring session with twelve participants from the communities.

Cauchari-Olaroz initiated the Responsible Minerals Initiative (RMI) Responsible Sourcing Assurance Process (“RMAP”) to ensure its supply chain adheres to the highest ethical and environmental standards. In December 2024, it was officially added to the RMAP active list. Subsequently, in June 2025, the operation successfully completed an on-site audit as part of the RMAP requirements.

9 AISC includes sustaining capex, tailings management and closing costs. Provincial royalties represent an additional $217/t - $463/t at a price range of $12,000/t - $20,000/t.

FINANCIAL INFORMATION OF EXAR

The following is the condensed financial information of Exar on a 100% basis, as amended to reflect the Company’s accounting policies. The Company holds a 44.8% economic interest in Exar and accounts for its interest using the equity method of accounting. Accordingly, the recorded results and financial position of Exar are included in a single line item in the Company’s consolidated statements of comprehensive loss and financial position, respectively.

The increase in current assets reflects higher cash and cash equivalents, trade receivables, and prepayments for reagents, partially offset by inventory sold during the period. Cash and cash equivalents included the remaining proceeds from the $120 million debt facilities closed in Q2 2025, as further detailed below.

During the nine months ended September 30, 2025, as part of a restructuring of loans (the “Restructuring”), the Company and Ganfeng amended and restated loan agreements relating to loans advanced to Exar Capital. Concurrently, Exar Capital amended and restated agreements relating to the loans advanced to Minera Exar (collectively, the “Amendments”), revising interest rates to market levels effective for fiscal year 2025 and subsequent periods and extending the maturity dates, with revised maturity dates ranging from 2028 to 2035. These modifications were treated as an extinguishment of the existing loans and the

issuance of new loans at market rates of interest. As part of the Restructuring, on August 27, 2025, Exar Capital assigned certain loan receivables from Exar to the Company and Ganfeng in exchange for the cancellation of a portion of the loans outstanding from Exar Capital to the Company and Ganfeng. The total carrying value of the loans assigned was $208.1 million, with the Company’s portion amounting to $101.9 million. In exchange, the Company cancelled loans owed by Exar Capital with carrying value of $99.4 million. The assigned loans receivable from Exar were subsequently settled through a capital contribution by the Company and Ganfeng to Exar. As such, during the nine months ended September 30, 2025, loans from Exar Capital decreased as a result of the capitalization of certain loans to Exar’s equity by the Company and Ganfeng, partially offset by accrued interest.

As of September 30, 2025, Exar held $285.1 million in third-party debt at the official foreign exchange rate (2024 – $210.4 million) and $53.6 million in cash (2024 – $11.2 million), resulting in net debt of $231.5 million (2024 – $199.2 million). The Company’s proportionate share of this net debt is $113.5 million.

Exar’s debt includes $50 million of bonds issued in Argentina in November 2024, bearing 8% annual interest, payable semi-annually. The bonds mature in two tranches in May and November 2027, and the proceeds were used to repay Exar’s short-term debt.

As of September 30, 2025, the remaining $235.1 million of debt is scheduled to mature within the next 12 months. The Company and Ganfeng have negotiated a three-year extension for $100 million of this amount, which has been approved by the regulatory authority and is currently in the process of implementation. Accordingly, together with the bonds, approximately $150 million of third-party debt is being refinanced into long-term debt with a maturity of three years, with the remaining $135.1 million due within the next 12 months. The remaining $135.1 million of debt includes the $120 million in bank debt facilities closed in Q2 2025 and fully drawn in Q3 2025 to refinance maturing short-term loans and for other purposes. These loans were competitively priced at an approximate rate of SOFR plus 2.5%, including fees, reflecting Exar’s ability to access credit on favorable terms. A portion of these debt proceeds remained in Exar’s cash balance at September 30, 2025. The Company continues to work with Ganfeng to pursue additional long-term financing options as lending conditions in Argentina improve, supporting Exar’s longer-term growth plans.

In addition to the Company’s equity interest in Exar, the Company has total outstanding loans of $374.1 million to the Cauchari-Olaroz project as of September 30, 2025, comprising $302.0 million through Exar Capital and $72.1 million to Exar through PGCo. (including accrued interest). Exar Capital, in turn, has an outstanding balance of $905.4 million owed by Exar.

SELECTED FINANCIAL INFORMATION OF THE COMPANY

Liquidity

As of September 30, 2025, the Company had a cash and cash equivalents balance of $64.0 million, receivables of $19.5 million from purchasers of lithium carbonate, and $75.0 million available under its undrawn limited recourse loan facility with Ganfeng (available until the end of 2025), to settle current liabilities of $25.1 million, being payables from purchases of lithium carbonate of $19.5 million and other payables of $5.6 million (excluding equity-settled Convertible Notes).

The operations of Lithium Americas (NewCo) (as defined below) have been presented in prior periods as a discontinued operation.
Non-IFRS measure. Refer to section “Non-IFRS and Other Financial Measures”

On July 31, 2023, at the annual general and special meeting of the Company, the shareholders approved the separation of the former Lithium Americas Corp. into Lithium Argentina and a new entity, Lithium Americas Corp. (“Lithium Americas (NewCo)”), pursuant to a statutory plan of arrangement (the “Separation”). The Separation was completed on October 3, 2023. As a result of the transaction, the Company transferred its North American business, including, among other assets, the Thacker Pass Project (“Thacker Pass”) and $275.5 million of cash to Lithium Americas (NewCo).

Discussion of Quarterly Trends

Q3 2025: Total assets decreased primarily due to the Company’s share of loss from the Cauchari-Olaroz project of $52.5 million, which reduced the carrying amount of the investment in Exar. During the quarter, as part of the Restructuring, certain loans from Exar Capital were assigned and subsequently capitalized into Exar’s equity by the Company and Ganfeng. The capitalization increased the investment balance but also resulted in the recognition of previously unrecognized losses from 2024, leading to a net reduction in total assets. Lower cash balances and reduced receivables from lithium carbonate sales further contributed to the decrease, partially offset by accrued interest on loans to Exar and Exar Capital.

Total liabilities decreased mainly due to the derecognition of the deferred tax liability and lower payables to Exar, partially offset by accrued interest on the Convertible Notes.

Q2 2025: Total assets increased due to accrued interest on loans to Exar and Exar Capital and higher receivables from lithium carbonate sales, offset by lower cash. Liabilities rose from interest accruals on Convertible Notes and increased payables to Exar.
Q1 2025: Total assets declined mainly due to operating cash outflows, partially offset by interest receivables and increased trade receivables. Liabilities rose from Convertible Notes interest, partly offset by lower payables.

Q4 2024: Growth in total assets was driven by accrued interest on loans to Exar Capital and higher lithium receivables, offset by reduced cash balances. Liabilities increased due to higher Convertible Notes interest and Exar payables.
Q3 2024: PGCo, previously wholly owned, issued 14.9% of its shares to Ganfeng for $70.0 million. PGCo loaned $65.0 million to Exar, funded from this transaction. Liabilities increased primarily due to Convertible Notes interest and Exar payables.
Q2 2024: Total assets were flat. Liabilities decreased by $3.9 million, driven by a $10.7 million reduction in deferred tax liabilities due to inflation adjustments on the Pastos Grandes tax base, partially offset by higher payables to Exar.
Q1 2024: Decrease in assets was driven by cash used in operations and a reduction in investment in Cauchari-Olaroz based on the Company’s share of results. This was offset by increased loans to Exar Capital. Liabilities were generally stable.
Q4 2023: Total assets declined due to the completion of the Separation. Net income included a $1.27 billion gain on distribution of assets to shareholders. The fair value of the assets distributed was $1.68 billion, based on the October 4, 2023, trading price of Lithium Americas (NewCo).

The Company reported a net loss (attributable to equity holders of Lithium Argentina) of $75.7 million for the nine months ended September 30, 2025, compared to a net loss of $10.4 million for the same period in 2024. The higher loss was primarily driven by:

a significantly higher share of loss from Cauchari-Olaroz ($53.4 million in 2025 vs. $27.8 million in 2024). The current period’s share of losses from the Cauchari-Olaroz project of $53.4 million comprises current year recognized losses of $27.3 million and previously unrecognized losses of $26.1 million from 2024, which were recognized following the capitalization of loans as part of the investment in Minera Exar.
a lower gain on financial instruments measured at fair value ($0.1 million in 2025 vs. $11.1 million in 2024), primarily reflecting lower fair value movement of the Convertible Notes derivative liability during the period, as the impact of the decrease in the risk-free rate and passage of time was largely offset by the increase in the Company’s share price;
a deferred tax recovery of $10.7 million in comparative period versus no deferred tax impact for the nine months ended September 30, 2025 ;
higher non-cash equity compensation expense of $11.8 million (2024 – $5.1 million), due to the timing and value of equity awards granted;
a loss from the JEMSE receivable of $9.3 million (2024 - $nil). This total loss consists of $3.4 million related to the previous JEMSE receivable, arising from an adjustment to its carrying value based on revised cash flow estimates prior to the 2025 debt restructuring and $5.9 million related to an additional JEMSE receivable recognized as part of the 2025 debt restructuring transaction. The Company recorded this additional receivable at a fair value of $2.8 million and reduced its investment by $8.7 million, resulting in the $5.9 million loss;
a foreign exchange loss of $0.3 million (2024 – gain of $1.8 million); and
increased general and administrative expenses, finance costs, and transaction-related expenditures.

These were partially offset by:

higher finance income of $41.1 million (2024 – $37.9 million), primarily from interest on loans to Exar and Exar Capital; and
reduced exploration and evaluation expenditures of $5.3 million (2024 – $7.6 million), due to lower project activity and Company-wide cost control.

Purchases and sales of lithium carbonate

During the nine months ended September 30, 2025, the Company purchased its share of Exar’s lithium carbonate shipped during the period, with Ganfeng purchasing the remaining product shipped. The Company sold the purchased lithium carbonate to Ganfeng and BCP Innovation PTE. LTD (“Bangchak”), a wholly-owned subsidiary of Bangchak Corporation Public Company Ltd. and acted in the capacity of agent in such sales transactions, as the Company’s acquisition of title to lithium carbonate was simultaneous with its sale to Ganfeng and Bangchak. As a result, the Company was not directly exposed to inventory or price risk related to the lithium carbonate.

Since there was no net commission earned by the Company, there was no impact on the Company’s statement of comprehensive loss for the nine months ended September 30, 2025.

As at September 30, 2025, the Company had a payable of $19.5 million to Exar for lithium carbonate purchases and receivables totaling $19.5 million from Ganfeng for sales of lithium carbonate, as disclosed on the statement of financial position.

Expenses

Exploration and evaluation expenditures: $5.3 million (2024 – $7.6 million), primarily related to Pastos Grandes, reflecting lower activity and cost reduction efforts.

Equity compensation: $11.8 million (2024 – $5.1 million), a non-cash expense related to RSUs, PSUs, and stock options. The increase compared to the prior year reflects the higher number and fair value of awards granted during the current period.
General and administrative expenses: $11.4 million (2024 – $10.6 million), including:
Salaries and benefits: $5.7 million (2024 – $4.1 million).
Professional fees: $2.4 million (2024 – $2.8 million).
Office and administrative expenses: $2.2 million (2024 – $2.1 million).

Other Items

Gain on financial instruments: $0.1 million (2024 – $11.1 million), from fair value remeasurement of the Convertible Notes derivative liability. The fair value of the derivative as at September 30, 2025, was estimated using a partial differential equation method with Monte Carlo simulation, with the following inputs: volatility of 68.0%, share price of $3.34, a risk-free rate of 3.66%, an expected dividend of 0%, and a credit spread of 7.50%. The gain primarily reflected the passage of time and a decrease in the risk-free rate from 4.25% to 3.66%, partially offset by the increase in the Company’s share price from $2.62 as at December 31, 2024, to $3.34 as at September 30, 2025.
Finance and other income: $41.1 million (2024 – $37.9 million), including:
Interest from Exar Capital: $33.6 million.
Interest from PGCo loans to Exar: $4.7 million.
Interest on cash and deposits: $2.3 million (2024 – $3.2 million), with the decrease primarily due to lower cash balances and interest rates during the period.
Finance and other costs: $22.1 million (2024 – $18.6 million), mainly representing interest on Convertible Notes.
Transaction costs: $3.2 million (2024 – $2.1 million), mainly related to the Continuation.

The Company reported a net loss (attributable to equity holders of Lithium Argentina) of $64.5 million for Q3 2025, compared to a net loss of $2.4 million for Q3 2024. The higher loss in Q3 2025 was primarily attributable to:

a significantly higher share of loss from Cauchari-Olaroz ($52.5 million in Q3 2025 vs. $1.3 million in Q3 2024). In Q3 2025, the Company capitalized certain loans to Exar’s equity, increasing its investment in Exar. As a result of this capitalization, the Company’s investment balance became positive, leading to the recognition of previously unrecognized losses of $26.1 million, in addition to the Company’s share of current period losses of $26.4 million;
a loss from the JEMSE receivable of $9.3 million (2024 – $nil), which reflects an adjustment of $3.4 million related to the previously recognized JEMSE receivable, and an adjustment of $5.9 million related to an additional JEMSE receivable arising from the 2025 debt restructuring;
higher equity compensation expense, totaling $3.2 million in Q3 2025 (2024 – $2.5 million), primarily due to the timing and fair value of equity awards granted during the period;
higher finance and other costs, mainly from interest accrued on the Convertible Note; and
lower finance and other income of $12.9 million (2024 – $13.2 million), primarily from interest on loans advanced to Exar and Exar Capital and lower interest earned on cash balances.

These impacts were partially offset by:

deferred tax recovery of $ 1.8 million in Q3 2025. In Q3 2025, the Company reassessed its deferred tax position and concluded that the temporary differences recognized upon Continuation were no longer applicable under current tax circumstances. As a result, the previously recognized deferred tax liability of $1.8 million was derecognized, generating a deferred tax recovery of $1.8 million for the quarter.
reduced exploration and evaluation expenditures, consistent with decreased project activity during Q3 2025; and

slightly lower general and administrative expenses compared to Q3 2024.

As at September 30, 2025, the Company had cash and cash equivalents of $64.0 million and an undrawn $75 million available under the limited recourse loan facility with Ganfeng.

The Company expects that its existing cash balance, proceeds from operations, and other sources of financing will provide sufficient resources to fund the planned expenditures at Pastos Grandes, Sal de la Puna, its share of Cauchari-Olaroz planned expenditures, as well as general and administrative costs and other obligations.

The timing and amount of expenditures for Pastos Grandes are within the Company’s control due to its controlling interests in the project. However, pursuant to the agreements governing Cauchari-Olaroz and Sal de la Puna, decisions regarding capital budgets for these projects require agreement between Lithium Argentina and the projects’ co-owner, Ganfeng.

The Company continues to support the operation of Cauchari-Olaroz and the development of its other projects. The Company’s capital resources are driven by the status of its assets, the operation at Cauchari-Olaroz, and its ability to secure investor support for its initiative.

In the long-term, the Company expects to meet its obligations and fund the development of its projects through the financing plans described above. However, given the conditions associated with such financing, there can be no assurance that the Company will successfully complete all of its contemplated financing plans. Except as disclosed, the Company is not aware of any trends, demands, commitments, events, or uncertainties that are likely to materially affect its liquidity and capital resources, either positively or negatively, in the near or foreseeable future. The Company does not engage in currency hedging to mitigate any risks related to currency fluctuations.

Operating Activities

Cash used in operating activities for the nine months ended September 30, 2025, was $27.4 million (2024 – $17.0 million). The significant components of operating activities are discussed in the “Results of Operations” section above.

Investing Activities

Cash provided by investing activities for the nine months ended September 30, 2025, was $6.4 million (2024 – $83.6 million cash used in investing activities).

During the nine months ended September 30, 2025, the Company received a partial repayment of its outstanding loan to Exar Capital totaling $3.9 million. Additionally, the Company received $3.0 million from the sale of Cauchari East mineral rights to the Cauchari-Olaroz project, which was partially offset by a $0.3 million contribution to its investment in Sal de la Puna and $0.2 million in capital expenditures, including additions to exploration and evaluation assets.

Financing Activities

Equity-settleable Convertible Notes

On December 6, 2021, the Company closed an offering (the “Offering”) of $225 million aggregate principal amount of 1.75% convertible senior notes due in 2027 (the “Convertible Notes,” “Equity-settleable Convertible Notes,” or “Notes”). On December 9, 2021, the initial purchasers under the Offering exercised, in full, their option to purchase up to an additional $33.75 million aggregate principal amount of the Convertible Notes, increasing the total Offering size to $258.75 million.

Pursuant to the indenture governing the terms of the Convertible Notes, as amended by a first supplemental indenture to reflect the name change of the Company in connection with the Separation and a second supplemental indenture to reflect the effects of the Continuation (the “Indenture”), the holders of the Convertible Notes, at their election, were permitted to surrender the Convertible Notes for conversion (i) into shares of the Company during the approximate 30-trading day period prior to the closing of the Continuation and (ii) into shares of the Company during the period from and after the closing of the Continuation until approximately the 35th trading day after the closing of the Continuation. The Conversion Rate (as defined in the Indenture) for the Convertible Notes was initially 21.2307 shares per $1,000 principal amount of the Convertible Notes. Pursuant to the terms and conditions of the Indenture, the Conversion Rate for the Convertible Notes was adjusted on October 17, 2023, to 52.6019 shares of the Company per $1,000 principal amount of the Convertible Notes based on the trading prices of the Company’s shares over the preceding 10-trading day period due to the Separation transaction. The Conversion Rate for the Convertible Notes was not adjusted as a result of the Continuation. None of the Convertible Notes were surrendered for conversion during the permitted conversion period in connection with the Continuation.

Loan Facility

As at September 30, 2025, the limited recourse loan facility with Ganfeng remains undrawn with $75 million available under the facility until the end of 2025.

CURRENT SHARE DATA

Issued and outstanding securities of the Company as at the date of this MD&A are as follows:

Shares issued and outstanding	162.3 million
Restricted Share Units (RSUs)	7.4 million
Deferred Share Units (DSUs)	1.0 million
Stock Options	2.7 million
Performance Share Units (PSUs)	0.2 million
Shares, fully diluted	173.6 million

In February 2023, General Motors Holdings LLC (“GM”) acquired approximately 15,000,000 shares of the Company. In connection with that transaction, GM agreed to a ‘lock-up’ restricting the transfer of those shares pursuant to the terms of an investor rights agreement with the Company. The principal lock-up expired in October 2024 (with certain specified transfer limitations remaining in place), and GM is no longer contractually restricted from selling its shares of the Company through the facilities of a stock exchange.

RELATED PARTY TRANSACTIONS

Any transactions between the Company with Exar, Exar Capital, and Sal de la Puna are considered related party transactions (refer Note 5, 6, 7 and 8 of the Q3 2025 financial statements).

Exar, the Company’s equity accounted investee, entered into the following transactions with companies controlled by the family of its director, who is also a director of Lithium Argentina:

Option agreement with Grupo Minero Los Boros S.A. on March 28, 2016, for the transfer of title to certain mining properties that form part of Cauchari-Olaroz.
Expenditures under a construction services contract for Cauchari-Olaroz with Magna Construcciones S.R.L. (“Magna”) were $0.05 million for the nine months ended September 30, 2025 (on a 100% basis).
Service agreement with a consortium 49% owned by Magna, entered into in Q1 2022, for the servicing of the evaporation ponds at Cauchari-Olaroz over a five-year term, with total consideration of $68 million (excluding VAT). During the nine months ended September 30, 2025, Exar spent $16.1 million (excluding VAT) on the servicing of the evaporation ponds at Cauchari-Olaroz.
During the nine months ended September 30, 2025, Exar Capital facilitated the purchase of certain materials and supplies on behalf of Exar amounting to $14.1 million (2024 – $12.6 million). These transactions are settled by Exar upon delivery of the goods and receipt of supplier documentation.

As of September 30, 2025, Exar’s outstanding third-party debt amounted to $285.1 million (2024 – $210.4 million), while its cash balance was $53.6 million (2024 – $11.2 million), resulting in a total net debt of $231.5 million (2024 – $199.2 million). The total debt includes the following:

Approximately $220 million in loans from major international banks, secured by guarantees and standby letters of credit arranged by Ganfeng, which are due within twelve months from September 30, 2025. The Company has provided a guarantee to Ganfeng for its 49% share, amounting to $107.8 million, in respect of these loans. The Company and Ganfeng have negotiated a three-year extension of the maturity of $100 million of these loans, which has been approved by the regulatory authority and is in the process of implementation.
$10 million in loans secured by local bank guarantees arranged by Exar, due in 2025.
Approximately $50 million in unsecured bonds issued by Exar in November 2024, carrying a contractual interest rate of 8% with semi-annual interest payments. The bonds’ principal will mature in two tranches: the first tranche of $25 million is due in 30 months, on May 11, 2027, while the second tranche of $25 million will mature in 36 months, on November 11, 2027.

As of September 30, 2025, $235.1 million is scheduled to mature within the next 12 months. The Company and Ganfeng have negotiated a three-year extension for $100 million of this amount, which has been approved by the regulatory authority and is in the process of implementation. As such, together with the bonds, approximately $150 million of the third-party debt is being refinanced into long-term debt with maturity of three years, with the remaining $135.1 million due within the next 12 months. The remaining $135.1 million of debt includes the $120 million in bank debt facilities closed in Q2 2025 and fully drawn in Q3 2025 to refinance maturing short-term loans and for other corporate purposes. These loans were competitively priced at an approximate rate of SOFR plus 2.5%, including fees, reflecting Exar’s ability to access credit on favorable terms. A portion of these debt proceeds remained in Exar’s cash balance at September 30, 2025. The Company continues to work with Ganfeng to pursue additional long-term financing options as lending conditions in Argentina improve, supporting Exar’s longer-term growth plans.

Offtake Arrangements

Each of the Company and Ganfeng are entitled to a share of offtake from production at Cauchari-Olaroz. The Company will be entitled to 49% of the offtake, which would amount to approximately 19,600 tpa of lithium carbonate, assuming full capacity is achieved. The Company has entered into offtake agreements with both 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). The balance of the Company’s offtake entitlement, amounting to up to approximately 3,800 tpa of lithium carbonate, remains uncommitted, except for limited residual rights available to Bangchak if production does not meet full capacity

CONTRACTUAL OBLIGATIONS

As at September 30, 2025, the Company had the following contractual obligations on an undiscounted basis:

Total

All values are in US Dollars.

¹Include principal and interest/finance charges.

The Convertible Notes are classified as current liabilities as at September 30, 2025, since the 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 Notes would be convertible at the option of the holders and upon conversion, the Notes may be settled, at the Company’s election, in shares, cash, or a combination thereof. The table above summarizes the contractual maturities as of September 30, 2025, with respect to the Convertible Notes, assuming that such conditions will not be satisfied before the due date.

The Company’s commitments related to royalties and other payments are disclosed in Note 11 of the Q3 2025 financial statements filed on SEDAR+ and EDGAR, most of which will be incurred in the future if the Company continues to hold the subject property, proceeds with construction, or begins production.

NON-IFRS AND OTHER FINANCIAL MEASURES

Cash Operating Costs and Total Cash Costs per Tonne

Lithium Argentina reports “Cash Operating Costs per tonne” and “Total Cash Costs per tonne” as key non-GAAP financial measures or ratios. These non-GAAP financial measures or ratios do not have a standardized meaning under IFRS and might not be comparable to similar financial measures disclosed by other issuers. The most directly comparable IFRS measure is Cost of Sales. These metrics provide investors with insight into the Company’s cost structure by excluding non-cash and non-operating items, thereby enabling better comparability of operating performance.

Cash Operating Cost (C1) includes all expenditures incurred at the site, such as brine management, lithium plant processing, site and provincial office overheads, and inventory adjustments. These costs also include project general and administrative costs and sales logistics costs. Total Cash Costs (C2) include all C1 costs, along with selling costs, export duties (net of refunds) and provincial royalties. Tonnes are reported on a tonnes sold basis at FOB Buenos Aires port. Exar covers the cost of transporting lithium carbonate to the port, while the delivery cost to the buyer's factory in China, along with processing and other costs are subtracted from the sales price.

Average realized lithium price

Lithium Argentina reports “average realized lithium price” as a key non-GAAP financial measure. This non-GAAP financial measure does not have a standardized meaning under IFRS and might not be comparable to similar financial measures disclosed by other issuers. Average realized lithium price per tonne is defined as lithium revenue divided by total lithium tonnes sold.

Current liabilities excluding equity-settleable Convertible Notes

Lithium Argentina reports “current liabilities excluding equity-settleable Convertible Notes” as a key non-GAAP financial measure. This non-GAAP financial measure does not have a standardized meaning under IFRS and might not be comparable to similar financial measures disclosed by other issuers. Current liabilities excluding equity-settleable Convertible Notes are defined as total current liabilities less the equity-settleable Convertible Notes that the Company may settle in equity.

Management believes this metric provides a useful indication of the Company’s cash-based obligations, as the Convertible Notes may be settled in shares at the Company’s discretion and therefore do not necessarily represent an imminent cash outflow. Current liabilities excluding equity-settleable Convertible Notes are intended to provide additional information only and do not have any standardized definition under IFRS and should not be considered in isolation or as a substitute measure of performance prepared in accordance with IFRS.

FINANCIAL INSTRUMENTS

Measurement

Financial instruments recorded at fair value on the consolidated statements of financial position of Q3 2025 financial statements and presented in fair value disclosures are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy has the following levels:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2 – Inputs other than quoted prices that are observable for assets or liabilities, either directly or indirectly; and

Level 3 – Inputs for assets and liabilities that are not based on observable market data.

The fair value hierarchy requires the use of observable market inputs whenever such inputs are available. A financial instrument is classified at the lowest level of the hierarchy for which a significant input has been used in measuring fair value. The Convertible Notes derivatives are classified at level 2 of the fair value hierarchy and are measured at fair value on a recurring basis. Cash and cash equivalents, receivables and payable associated with lithium carbonate sales and purchases, other receivables/payables, and the debt host of the Convertible Notes are measured at amortized cost on the statement of financial position. As at September 30, 2025, the fair value of financial instruments measured at amortized cost approximates their carrying value.

Risk

The Company manages risks to minimize potential losses. Its primary objective is to ensure that risks are properly identified and monitored, and that its capital base is adequate relative to those risks. The principal risks affecting the Company’s financial instruments are described below.

Credit Risk

Credit risk refers to the potential for loss due to a counterparty’s inability to meet its financial obligations. The Company is exposed to credit risk through its cash, cash equivalents, receivables, and loans to Exar Capital and Exar. To limit its exposure, the Company places its cash and cash equivalents with reputable financial institutions and regularly monitors their creditworthiness. While a significant portion of the Company’s cash is currently held with a single financial institution, the Company plans to diversify its holdings to reduce concentration risk.

As at September 30, 2025, the Company performed an expected credit loss assessment on the loans to Exar Capital and Exar, considering the anticipated future performance of the Cauchari-Olaroz project and its associated cash flows. The assessment did not indicate any significant credit risk or factors that would lead

to default. Similarly, the Company assessed the credit risk for its receivables, which did not identify any significant credit risk or factors that would result in default, as the majority of these receivables were settled after September 30, 2025.

Liquidity Risk

Liquidity risk is the risk that the Company may not be able to meet its financial obligations as they come due. The Company manages liquidity by assessing both current and projected liquidity requirements under normal and stressed conditions. This ensures it maintains adequate reserves of cash and cash equivalents to meet its short- and long-term obligations. The Company prepares annual budgets, which are regularly monitored and updated as necessary.

Market Risk

Market risk encompasses various risks, including those related to market prices, share price fluctuations, and currency movements, which can affect the fair values of financial assets and liabilities. The Company is exposed to foreign currency risk, as described below.

Foreign Currency Risk

The Company’s operations in foreign countries are subject to currency fluctuations, which may affect its financial results. The Company and its subsidiaries and associates have a US dollar functional currency, and it incurs expenditures in Canadian dollars (“CDN$”), Argentine Pesos (“ARS$”), Swiss francs (“CHF”) and US$, with the majority of the expenditures being incurred in US$ by the Company’s subsidiaries and investees. As at September 30, 2025, the Company did not hold significant amounts of cash and cash equivalents denominated in CDN$, ARS$, and CHF.

Estimation Uncertainty and Accounting policy judgments

Please refer to the Company’s annual MD&A for the year ended December 31, 2024, for Estimation Uncertainty and Accounting Policy Judgments disclosure. The nature and amount of significant estimates and judgements made by management in applying the Company’s accounting policies and the key sources of estimation uncertainty as well as accounting policies applied during the nine months ended September 30, 2025, were substantially the same as those that management applied to the consolidated financial statements as at and for the year ended December 31, 2024.

NEW IFRS PRONOUNCEMENTS

IFRS 18 Presentation and Disclosure in Financial Statements

In April 2024, the International Accounting Standards Board (“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.

Amendments to IFRS 9 and IFRS 7 – Amendments to the Classification and Measurement of Financials Instruments

In May 2024, the IASB issued amendments to IFRS 9 and IFRS 7, Amendments to the Classification and Measurement of Financials Instruments. These amendments updated classification and measurement requirements in IFRS 9 Financial Instruments and related disclosure requirements in IFRS 7 Financial

Instruments: Disclosures. The IASB clarified the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they meet the solely payments of principal and interest criterion, including financial assets that have environmental, social and corporate governance (ESG)-linked features and other similar contingent features. These amendments require additional disclosures for financial instruments with contingent features that do not relate directly to basic lending risks and costs and amended disclosures relating to equity instruments designated at fair value through other comprehensive income.

Management, including the CEO and CFO, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as defined in the rules of the SEC and the Canadian Securities Administrators, as at September 30, 2025. Based on this evaluation, the CEO and CFO have concluded that our disclosure controls and procedures were effective as at September 30, 2025.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s management, including the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting. Any system of internal control over financial reporting, no matter how well-designed, has inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

There have been no significant changes in our internal controls over financial reporting during the nine months ended September 30, 2025, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management, including the CEO and CFO, has used the Committee of Sponsoring Organizations of the Treadway Commission (COSO) 2013 framework to evaluate the effectiveness of our internal control over financial reporting. Based on this assessment, the Company’s management, including the CEO and CFO, has concluded that as at September 30, 2025, the Company’s internal control over financial reporting was effective.

The effectiveness of our internal controls over financial reporting has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, which has expressed its opinion in its report included with our annual consolidated financial statements for the financial year ended December 31, 2024.

Lithium Argentina Reports Third Quarter 2025 Results

and results of PPG Scoping Study

November 10, 2025 – Zug, Switzerland: Lithium Argentina AG (“Lithium Argentina” or the “Company”) (TSX: LAR) (NYSE: LAR) today announced its third quarter 2025 results1.

The Company will hold a webcast and conference call at 8:00am today to discuss its third quarter 2025 result. Additionally, Sam Pigott, Chief Executive Officer of Lithium Argentina, Wang Xiaoshen, Chief Executive Officer of Ganfeng Lithium Group Co., Ltd. (“Ganfeng”) along with other members of their executive teams will join the call to discuss the results of the Pozuelos Pastos Grandes (the “PPG Project” or “PPG”) Scoping Study and development plans in Argentina.

Sam Pigott, Lithium Argentina’s President and CEO, commented:

“The third quarter demonstrated continued operational performance and the benefits of our ongoing initiatives to optimize production, enhance process efficiency and reduce long-term costs. We remain confident in exceeding the low-end of our 2025 targets.

While optimization work continues, we are very encouraged by the plant’s performance, with production rates sustaining around 90% of nameplate capacity or higher for extended periods. Looking ahead to 2026, our focus is on maintaining higher production levels while implementing targeted long-term improvements to further strengthen the business.

On the balance sheet, we were pleased to announce a new $130 million, six-year debt facility from Ganfeng. This facility provides additional flexibility to optimize our capital structure at the corporate level and further enhance shareholder value.

Concurrent with our quarterly results, we also released the PPG Scoping Study, marking a pivotal milestone in advancing what we believe will become one of the world’s most significant new lithium operations. This study confirms a clear pathway to large-scale, low-cost production in Salta, reinforcing our confidence in the long-term growth of lithium demand and Argentina’s role in a globally diversified lithium supply chain.”

Highlights

Cauchari-Olaroz2

Production: Lithium carbonate production totaled approximately 8,300 tonnes in the third quarter of 2025. The operation focused on improving consistency while implementing improvements designed to enhance long-term efficiency to better position the operation in the future.
Lithium carbonate production for the nine months ended September 30, 2025, was approximately 24,000 tonnes, keeping the project on track to surpass the low end of the 2025 guidance of 30,000 – 35,000 tonnes.
Operating Costs: The cost of sales for the third quarter of 2025 was $57 million, with cash operating costs of $6,285 per tonne3 of lithium carbonate sold.
For the nine months ended September 30, 2025, cash operating costs per tonne totaled about $6,3223. Third quarter costs were impacted by the recognition of deferred maintenance cost as part of ongoing optimization programs designed to further reduce costs.

3 Cash operating costs includes all expenditures incurred at the site such as brine management, lithium plant processing, site and provincial office overheads and inventory adjustments. These costs also include project general and administrative costs and sales logistics costs. Cash operating cost per tonne is a non-GAAP financial measure or ratio and does not have a standardized meaning under IFRS and might not be comparable to similar financial measures disclosed by other issuers. See “Non-IFRS and Other Financial Measures”.

Earnings Release:

Third Quarter 2025

NEWS RELEASE

Pricing: Revenue for the third quarter of 2025 totaled $58 million, with an average realized price4 of approximately $7,522 per tonne of lithium carbonate sold.
At current lithium prices, the realized price for Cauchari-Olaroz is approximately $9,200 per tonne which reflects recovery in market pricing seen since July of this year.

Regional Growth and Cauchari-Olaroz Expansion

Regional Growth: The results of a comprehensive Scoping Study ("Scoping Study") for PPG5, for up to 150,000 tpa of lithium carbonate equivalent (“LCE”) lithium were disclosed by Lithium Argentina.
Highlights from the Scoping Study include.
An after-tax NPV8% of $8.1 billion and an IRR of 33% at $18,000/t price for lithium carbonate.
The consolidated PPG Project hosts a 15.1 Mt LCE measured and indicated resource, placing it among the largest undeveloped lithium brine resources.
Operating cash cost6 of $5,027/t estimated, positioning the PPG Project favorably amongst existing low-cost operations.
Initial capital cost for Stage 1 is estimated at $1.1 billion, including contingency.
Environmental permit secured from the Government of Salta for Stage 1 of PPG, following a rigorous 14-month review process.
Upon closing a previously announced new joint venture consolidating three projects (the “New JV”), Ganfeng will hold 67% and Lithium Argentina 33% of PPG.
Ganfeng and Lithium Argentina are jointly exploring financing options, including collaboration with potential customers and strategic partners for offtake and minority ownership interests.
Cauchari-Olaroz (Stage 2) Expansion: Cauchari-Olaroz is advancing an expansion plan considering an additional production capacity of 45,000 tpa of LCE (“Stage 2”).
Engineering of the 5,000 tpa demonstration plant continues in China with installation in Argentina targeted for 2026.
RIGI Investment Regime: Applications for Cauchari Stage 2 and PPG are being prepared under Argentina’s large investments’ incentive regime (“RIGI”) to support potential tax and fiscal benefits.

Financial and Corporate

As of September 30, 2025, Lithium Argentina held $64 million in cash and cash equivalents.
As of September 30, 2025, Cauchari-Olaroz had $231 million of net debt on a 100% basis.
In August 2025, Ganfeng agreed to provide Lithium Argentina with a 6-year, $130 million facility at an interest rate of SOFR plus 2.5% (“Debt Facility”), expected to close early 2026 with completion of the New JV enhancing liquidity and supporting the refinancing of existing corporate debt.

During the three months ended September 30, 2025, the Company reported a net loss of $64.5 million, compared to a net loss of $2.4 million in the prior-year period. The higher loss was primarily driven by a larger share of loss from the Cauchari-Olaroz Project totalling $52.5 million, which reflects current period losses of $26.4 million (mostly due to non-cash foreign exchange loss) as well as the recognition of previously unrecognized losses from 2024 of $26.1 million following the capitalization of certain loans to Minera Exar’s equity. These impacts were partially offset by a deferred tax recovery of $1.8 million, lower exploration expenditures, and slightly reduced general and administrative costs compared to Q3 2024.

This news release should be read in conjunction with Lithium Argentina’s unaudited condensed consolidated interim financial statements and management's discussion and analysis for the three and nine months ended September 30, 2025, which are available on SEDAR+ and EDGAR. All amounts are in U.S. dollars unless otherwise indicated.
