ZUG, Switzerland, Nov. 10, 2025 (GLOBE NEWSWIRE) -- 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.
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 NPV_8% 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 RESULTS

Selected consolidated financial information of the Company is presented as follows:

Cash and cash equivalents		64.0			85.5
Total assets		1,078.7			1,131.2

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.

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.

Notes:

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

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.

RECONCILIATION TO NON-GAAP MEASURES	2025						2024												2023
In USD millions (unless stated otherwise)	Q3			Q2			Q1			Q4			Q3			Q2			Q1			Q4
	$			$			$			$			$			$			$			$
Current liabilities		250.6			250.8			240.7			240.2			228.2			221.8			214.8			215.0
(-) Equity-settleable Convertible Notes		(225.5	)		(219.1	)		(213.5	)		(208.4	)		(204.5	)		(199.5	)		(200.5	)		(200.4	)
Current liabilities excluding equity-settleable Convertible Notes		25.1			31.7			27.2			31.8			23.7			22.3			14.3			14.6

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.
