Exhibit 99.2

BACKGROUND

Lithium Argentina AG (“Lithium Argentina”, the “Company” or “LAR”), is a Swiss-domiciled resource company with lithium projects located in Argentina. The Company’s head office and principal address is Dammstrasse 19, 6300 Zug, Switzerland. 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 registered common shares of the Company (the “Continuation”). 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”).

This Management’s Discussion and Analysis (“MD&A”) of Lithium Argentina provides an overview of Lithium Argentina's financial condition and results of operations for the three months ended March 31, 2026, and has been prepared as of May 12, 2026. It analyzes key factors influencing the Company's performance, including of the Cauchari-Olaroz lithium operation (“Cauchari-Olaroz”), in which the Company holds an interest in its financing activities, and market conditions.

This MD&A should be read in conjunction with the Company’s unaudited condensed consolidated interim financial statements and the notes thereto for the three months ended March 31, 2026 (“Q1 2026 financial statements”) and the audited consolidated financial statements and notes thereto for the year ended December 31, 2025 (“YE 2025 financial statements”). Refer to Notes 2 and 3 of Q1 2026 financial statements and YE 2025 financial statements for disclosure of the Company’s material accounting policies. All amounts are expressed in United States dollars (“US dollars” or “US$”), unless otherwise stated. References to CDN$ are in Canadian dollars. This MD&A includes certain statements that may be deemed “forward-looking statements,” “forward-looking information,” “future-oriented financial information,” and/or “financial outlook.” Readers should refer to the cautionary note in the section titled “Forward-Looking Statements” of this MD&A. Information contained on the Company’s website or in other documents referred to in this MD&A is not incorporated by reference herein and does not form part of this MD&A unless otherwise specifically stated.

Cauchari-Olaroz is a lithium carbonate operation located in Jujuy Province, northwestern Argentina. The Company owns a 44.8% interest in the operation through its equity stake in Minera Exar S.A. (“Exar”), an Argentine entity. Operations related to Cauchari-Olaroz are conducted through equity investees Exar and Exar Capital B.V. (“Exar Capital”), a Netherlands entity that provides project funding. The Company and Ganfeng Lithium Co. Ltd. (“Ganfeng”) collectively own 91.5% of Exar (with the remaining 8.5% held by Jujuy Energía y Minería Sociedad del Estado (“JEMSE”)), and 100% of Exar Capital, under a shareholders’ agreement.

As previously announced, the Company and Ganfeng have agreed to enter into a new joint venture (“New JV”) that will consolidate Ganfeng’s solely owned Pozuelos-Pastos Grandes project with Lithium Argentina’s Pastos Grandes project (85% owned) and the Sal de la Puna project (65% owned), (collectively, “PPG”). PPG is located in Salta Province. Upon closing the New JV, Ganfeng will hold a 67% interest and Lithium Argentina will hold a 33% interest in PPG.

Additional information relating to the Company, including key risk factors which may impact the Company’s business and financial condition, as well as other information, is contained in the Company’s Annual Report on Form 20-F for the year ended December 31, 2025 (“Form 20-F”), and other filings, which are available on the Company’s website at www.lithium-argentina.com, on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.

Highlights

Cauchari-Olaroz

The Company holds a 44.8% equity interest in Exar, the operating entity for Cauchari-Olaroz, and exercises joint control over all key decisions under the shareholder agreement. Operational and financial highlights below are presented on a 100% basis.

PPG and Cauchari-Olaroz Expansion

Operational Performance

Cauchari-Olaroz (on a 100% basis)5

Lithium carbonate production totaled approximately 9,660 tonnes in the first quarter of 2026, with the operation continuing to perform at or near design capacity. Over the past two quarters, production has averaged approximately 97% of the nameplate capacity, reflecting improved operating consistency and a strong foundation for continued optimization.

The Company reiterates its production 2026 guidance of approximately 35,000 to 40,000 tonnes of lithium carbonate at Cauchari-Olaroz.

Cost of sales for the first quarter of 2026 was $65.2 million, with cash operating costs of $5,3916 per tonne of lithium carbonate sold. Stable performance at near design capacity has enabled a greater focus on optimization initiatives, with structural and operational improvements continuing to drive reductions in unit costs. The Company continues to target long-term cash operating costs of approximately $5,400 per tonne.

Revenue for the first quarter of 2026 totaled $168.3 million, reflecting an average realized price of approximately $16,818 per tonne of lithium carbonate sold. Realized price reflects minimal adjustments for quality relative to battery-grade lithium carbonate prices.

Health and Safety

The Total Recordable Injury Frequency rate for Cauchari-Olaroz for the twelve months ended March 31, 2026 was 0.78 per 200,000 hours worked (including contractors at site).

The Lost Time Injury Frequency Rate for Cauchari-Olaroz for the twelve months ended March 31, 2026 was 0.09 per 200,000 hours worked (including contractors at site).

Cauchari-Olaroz remains committed to maintaining a safe, and supportive work environment, with ongoing efforts focused on strengthening safety practices.

Environmental and Social Responsibility

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. The operation is expected to achieve RMAP conformance shortly. This independent assessment validates that the Company’s due diligence and management systems align with internationally recognized responsible sourcing standards.

5 Information in this section is presented on a 100% basis of the Cauchari-Olaroz operation; the Company’s economic interest is 44.8%.

6 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”.

Mineral Resource and Reserve Estimation

During March 2026, the Company released an updated mineral resource and reserve estimate (“Updated Estimate”)7, which we believe confirms that Cauchari-Olaroz is not only a high-quality, low-cost operating asset, but also a growing, long-life resource base capable of supporting future expansion beyond the current 40,000 tpa LCE nameplate capacity. The expanded measured and indicated mineral resource estimate increased by 42% to 28.1 million tonnes (“Mt”) of LCE at an average grade of 562 mg/L lithium, to support the Stage 2 development plan expected in mid-2026.

The Updated Estimate shows a mineral reserve estimate reflecting the existing Stage 1 operation plan with a capacity of 40,000 tpa. The project life supports an additional 35-year operating period using the existing production wells from 2026 through 2060 consistent with the previous 40-year project life after incorporating past brine production and existing brine inventory. The estimate incorporates updated hydrogeological modeling and brine production data since 2018, further strengthening confidence in the long-term performance of the basin and supporting continued development.

PPG Project

Lithium Argentina has entered into a framework agreement with respect to the New JV to develop PPG. Upon closing, Ganfeng and Lithium Argentina will own 67% and 33%, respectively. 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.

A Scoping Study (“Scoping Study”) for PPG completed in November 2025 outlines 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 Scoping Study was filed producing an after-tax NPV8% of $8.1 billion and IRR of 33% at $18,000 per tonne lithium carbonate price. A sensitivity analysis of long-term lithium carbonate price of $20,000, more in line with current lithium prices estimates an after- NPV8% of $9.6 billion and IRR of 36%.

A technical report, prepared by Golder Associates (“Golder”), in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and Subpart 1300 of Regulation S-K (“SK 1300”), was filed. The technical report has an effective date of October 31, 2025. Unless otherwise indicated, all figures are in U.S. dollars and on a 100% basis.

7 See the detailed scientific and technical information on Cauchari-Olaroz prepared in accordance with NI 43-101 (including mineral resources and reserves estimates prepared in accordance with CIM Definition Standards adopted by the Canadian Institute of Mining, Metallurgy and Petroleum on May 10, 2014) and are also reported in accordance SK-1300. The estimates are supported by a technical report with an effective date of February 27, 2026 which was filed on SEDAR+ and with the SEC.

Scoping Study Results - Summary8

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. A sensitivity analysis of long-term lithium carbonate price on the economic results for the 150,000 tpa of LCE over a 30-year operating period is summarized below.

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 project has submitted its application to seek eligibility under Argentina’s Régimen de Incentivo para Grandes Inversiones (“RIGI”) framework to enhance fiscal stability and long-term competitiveness.

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

Exar’s Third Party Debt

As of March 31, 2026, Exar’s outstanding third-party debt, including accrued interest, amounted to $326.7 million at the official foreign exchange rate (2025 – $292.7 million), while its cash balance and short-term investments were $71.3 million (2025 – $86.8 million), resulting in third-party net debt of $255.4 million (2025 – $205.9 million). The Company’s proportionate share of this net debt was $125.2 million. In Q1 2026, Cauchari-Olaroz completed $85 million ($42 million for the Company’s share) in cash distributions from the operation, funded with cash on hand and partially additional third party loans secured with short-term investments.

Exar’s debt includes $50 million of bonds issued in Argentina in November 2024, bearing interest at 8% per annum, 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 March 31, 2026, the remaining $277.0 million of debt was scheduled to mature within the next 12 months. In 2025, the Company and Ganfeng negotiated an extension for $100 million of this amount to the end of 2027, which has been approved by the regulatory authority. The loan is secured by a standby letter of credit provided by Ganfeng. As the standby letter of credit was issued for a standard one-year term, the loan was structured with a one-year maturity to align with the term of the standby letter. Upon extension of the related standby letter of credit, the loan is automatically rolled over for another year of the remainder of the three-year term.

In early May 2026, the project secured an extension of the $100 million debt facility due in June 2026, for three years carrying same interest rate and customary terms and a potential increase of the facility to $170 million. In addition, the project secured $40 million in a two-year facility under SOFR+2.2% interest rate.

Accordingly, together with the bonds, approximately $250.0 million of third-party debt was refinanced into long-term debt, with the remaining $27.0 million due within the next 12 months. 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.

SELECTED FINANCIAL INFORMATION OF THE COMPANY

Liquidity and Going Concern

As at March 31, 2026, the Company had cash and cash equivalents of $97.4 million (2025 – $61.1 million) and equity-settleable convertible notes with a face value of $259 million due on January 15, 2027. In Q1 2026, the Company entered into a six-year $130 million debt facility with Ganfeng bearing interest at SOFR plus 2.5% (the “Debt Facility”). In addition, subsequent to March 31, 2026, LAR received $6.5 million from Exar Capital as a repayment of a portion of outstanding loan interest.

In Q1 2026, realized lithium carbonate prices increased to an average of approximately $16,818. For year 2026, Cauchari-Olaroz is expected to produce between 35,000 and 40,000 tonnes of lithium carbonate on a 100% basis and generate significant operational cash flow. In accordance with shareholder agreement that regulates governance of Cauchari-Olaroz, any excess cash flow (as defined in the shareholder agreement), from Cauchari-Olaroz is distributed among the Company and Ganfeng until a joint decision on any expansion plan is finalized.

The Company expects distributions from Cauchari-Olaroz to be sufficient to service the current portion of its long-term debt. However, its ability to maintain normal operations and meet these obligations ultimately depends on generating and repatriating sufficient cash flows from lithium carbonate production at Cauchari-Olaroz, or alternatively, securing additional financing.

The significance of the assumptions underlying the forecasted cash flows from Cauchari-Olaroz, the amount and timing of distribution of the cash flow to the Company and the requirement to satisfy the current portion of long-term debt, gives rise to material uncertainty which may cast significant doubt (or substantial doubt as contemplated by Public Company Accounting Oversight Board (“PCAOB”) standards) on the Company’s ability to continue as a going concern. Although the Company has been successful in obtaining distribution of cash flow from Cauchari-Olaroz and obtaining financing in the past, there can be no assurance that it will be able to distribute sufficient additional cash flow and obtain adequate financing in the future or that such financing will be available on terms acceptable to the Company.

If the Company is unable to continue as a going concern, material adjustments to the recoverability and amounts of assets and liabilities, the reported expenses, and the balance sheet classifications of assets and liabilities may be required. The Company’s consolidated financial statements do not include any adjustments that may result from the outcome of this uncertainty.

Quarterly Information

Selected consolidated financial information is as follows:

Notes: Quarterly amounts added together may not equal to the total reported for the period due to rounding.

Discussion of Quarterly Trends

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.

Total assets include the Company’s equity interest in the Cauchari-Olaroz project of $115.4 million and loan of $334.5 million through Exar Capital as of March 31, 2026. During the period, Exar fully repaid the loan outstanding to PGCo, including accrued interest, in the amount of $72.1 million.

Results of Operations

Three months ended March 31, 2026 (“Q1 2026”), versus Three months ended March 31, 2025 (“Q1 2025”)

The Company reported a net income of $7.5 million for Q1 2026, compared to a net loss of $7.2 million for Q1 2025. The change was primarily attributable to:

These impacts were partially offset by:

Purchases and sales of lithium carbonate

During the three months ended March 31, 2026, the Company was entitled to purchase its 49% share of Exar’s lithium carbonate production shipped during the period and, pursuant to its offtake agreements, sell that volume to Ganfeng and BCP Innovation PTE

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

Based on its principal versus agent assessment, the Company concluded that it acted as an agent in these transactions, as control of the lithium carbonate did not transfer to the Company prior to transfer to the end customers and the Company was not exposed to inventory or price risk. Accordingly, the Company did not recognize revenue or cost of sales in respect of these transactions.

As at March 31, 2026, the Company had a payable of $73.2 million to Exar for lithium carbonate purchases and receivables totaling $65.6 million from Ganfeng for lithium carbonate sales, as disclosed on the statement of financial position. The net payable balance reflects timing differences in payments at period end.

Expenses

Other Items

LIQUIDITY AND CAPITAL RESOURCES

As at March 31, 2026, the Company had cash and cash equivalents of $97.4 million.

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 (refer to section “Liquidity and going concern” above).

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’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 three months ended March 31, 2026, was $5.9 million (2025 – $15.1 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 three months ended March 31, 2026, was $52.4 million (2025 – $3.7 million).

During the three months ended March 31, 2026, the Company received $72.0 million as repayment of its outstanding loan to Minera Exar and $6.5 million as partial repayment of outstanding loan interest from Exar Capital. This was partially offset by the acquisition of $26.0 million in Exar Capital loan receivables from Ganfeng Lithium.

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.

The Convertible Notes are convertible at the option of the holders upon satisfaction of certain conditions (as disclosed in Note 12 of the Q1 2026 Financial Statements) 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.

CURRENT SHARE DATA

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

RELATED PARTY TRANSACTIONS

Any transactions between the Company and its equity-accounted investees Sal de la Puna, Minera Exar, and Exar Capital are considered related party transactions (refer Note 5, 6, 7 and 8 of the Q1 2026 Financial Statements).

The amounts due by Minera Exar and Exar Capital to related parties arising from such transactions are unsecured, non-interest bearing and have no specific terms of payment.

Compensation of Key Management

The Company’s key management consists of the executive management team, who supervise day-to-day operations, and independent directors on the Company’s Board of Directors, who oversee management. Their compensation was as follows:

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 March 31, 2026, the Company had the following contractual obligations on an undiscounted basis:

¹Include principal and interest/finance charges.

The Convertible Notes are classified as current liabilities as at March 31, 2026, 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 March 31, 2026, 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 Q1 2026 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

Exar Cash Operating Costs and Total Cash Costs per Tonne

Lithium Argentina reports Exar’s “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.

RECONCILIATION TO NON-GAAP MEASURES

Exar on a 100% basis

Notes: Quarterly amounts added together may not equal to the total reported for the period due to rounding.

Exar EBITDA and Adjusted EBITDA

Lithium Argentina reports “Exar EBITDA” and “Exar Adjusted EBITDA” as supplemental non-GAAP operational measures. These measures are presented on a 100% Exar basis and do not represent amounts attributable to Lithium Argentina or its shareholders. Lithium Argentina accounts for its 44.8% interest in Exar using the equity method and accordingly recognizes only its proportionate share of Exar’s net income or loss as a single line item in its consolidated statements of operations. These non-GAAP measures do not have a standardized meaning under IFRS and may not be comparable to similar measures disclosed by other issuers.

Management presents these measures to provide investors and other stakeholders with additional insight into the operational performance of the asset in which Lithium Argentina holds its primary interest.

Exar EBITDA is defined as Exar’s net income (loss) before income tax expense (recovery), finance costs (net), and depreciation and amortization. Exar Adjusted EBITDA further excludes foreign exchange gains and losses, gains and losses arising from derivative liabilities, other income and expense items of a non-cash or non-operating nature. These adjustments reflect items that management considers to be outside the ordinary course of operations at the Cauchari-Olaroz project and that may obscure period-to-period and peer-to-peer comparability of operating results. We believe that disclosing these measures assists readers in understanding the ongoing cash-generating potential of our significant equity investee in order to provide liquidity to fund its own needs and service its outstanding debt, as well as repay loans provided by Lithium Argentina and pay dividends.

Exar on a 100% basis

Note: The reconciliation above has been prepared using financial information from Exar's financial statements, adjusted for certain reclassifications to conform with Lithium Argentina's presentation. Figures may not sum due to rounding.

Derivative gains and losses reflect fair value changes related to an embedded derivative within Exar’s USD-denominated related party loans, that are contractually required to be settled in Argentine Pesos using the Blue-Chip Swap (“BCS”) exchange rate. The fair value of this embedded derivative fluctuates with changes in the spread between the BCS rate and the official Argentine exchange rate. These amounts are excluded from Adjusted EBITDA because they reflect non-operating fair value movements associated with financing arrangements rather than the underlying operating performance of the Cauchari-Olaroz project.

Average realized lithium price

Lithium Argentina reports Exar’s 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.

FINANCIAL INSTRUMENTS

Measurement

Financial instruments recorded at fair value on the consolidated statements of financial position and presented in fair value disclosures are classified within 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 embedded derivative associated with the Convertible Notes is measured at fair value on a recurring basis and is classified within Level 2, as the valuation is based on observable market inputs, including the Company’s quoted share price, observable volatility, risk-free interest rates and market-derived credit spread. The long-term receivable from JEMSE is not measured at fair value on a recurring basis; however, its fair value is disclosed and classified within Level 3, as it is determined using unobservable inputs, including assumptions regarding the timing of future cash flows of Exar and the applicable discount rate.

The Company’s financial assets and financial liabilities measured at amortized cost include cash and cash equivalents, receivables from purchasers for lithium carbonate, loans to Exar Capital, other receivables, accounts payable and accrued liabilities, payable to Exar for lithium carbonate purchases, and the debt host component of the Convertible Notes. As at March 31, 2026, the fair value of such financial instruments measured at amortized cost approximated their carrying value.

Risk

The Company manages risks to minimize potential losses. The primary objective of the Company’s risk management process is to ensure that risks are properly identified, monitored and managed, and that the Company maintains an appropriate capital base relative to its risk profile. The principal risks impacting the Company’s financial instruments are credit risk, liquidity risk and market risk.

Credit Risk

Credit risk refers to the potential for loss due to a counterparty’s inability to meet its financial obligations. The Company’s exposure to credit risk arises primarily from its cash and cash equivalents, receivables from purchasers of lithium carbonate, the long-term receivable from JEMSE, and loans advanced to Exar Capital and Exar.

The Company limits its exposure to credit losses on cash and cash equivalents by placing funds with major financial institutions and regularly monitoring their creditworthiness. As at March 31, 2026, the Company held its cash and cash equivalents with three financial institutions, enhancing diversification and liquidity management.

The Company actively monitors credit exposure to 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.

As at March 31, 2026, the Company performed an expected credit loss assessment on its loans to Exar Capital and Exar. Based on this assessment, management concluded that expected credit losses were not significant and, accordingly, no impairment allowance was recognized. The Company also assessed credit risk associated with receivables outstanding at year end and determined that no material impairment was required, as a substantial portion of these receivables was settled subsequent to March 31, 2026.

Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company’s approach to managing liquidity is to evaluate current and expected funding requirements under both normal and stressed conditions and to maintain sufficient cash and cash equivalent reserves to meet short- and long-term obligations. The Company prepares annual budgets and forecasts, which are reviewed and updated regularly.

As at March 31, 2026, the Company had cash and cash equivalents of $97.4 million and receivables from purchasers of lithium carbonate of $65.6 million to settle current liabilities of $82.3 million. The Company’s equity-settleable Convertible Notes with a face value of $258.8 million are due in January 2027.

For more about liquidity risk refer to Liquidity and Going Concern section above.

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 March 31, 2026, 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, 2025, 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 three months ended March 31, 2026, were substantially the same as those that management applied to the consolidated financial statements as at and for the year ended December 31, 2025.

NEW IFRS PRONOUNCEMENTS

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

The Company adopted the amendments to IFRS 9 and IFRS 7, Amendments to the Classification and Measurement of Financial Instruments effective January 1, 2026. These amendments 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.

Upon adoption, the Company applied the optional exemption permitting derecognition of financial liabilities settled through qualifying electronic payment systems at the date the payment instruction is released, rather than the settlement date. Management assessed the Company’s payment processes and determined that the criteria for application of this exemption are met.

The adoption of these amendments did not have a material impact on the Company’s condensed consolidated interim financial statements and did not result in any significant changes to the classification or measurement of financial instruments.

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.

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.

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.
