Analysis: what the 96% premium buys and what it costs

The structure is the interesting part, not the headline number. Lithium Argentina is refinancing a $259 million convertible with a $180 million convertible, closing the gap with cash, and simultaneously giving up a secured facility. The result is a smaller, unsecured, longer dated obligation at a 4.0% coupon. That is a genuine change in the shape of the balance sheet rather than a rollover.

The conversion price does most of the work. At $12.50, roughly 96% above the recent five day average, the note only becomes equity if the shares roughly double, and the accelerated redemption clause lets the company force the issue at par once the price holds 130% above that level. Read together, the two terms fix a six year cash interest obligation at 4.0% and defer any share issuance until the conversion condition is met. Neither party has committed to a price outcome, and neither the release nor the quarterly disclosure gives the volume weighted average price the premium is calculated from.

The dilution arithmetic is disclosed and modest. Full conversion takes Ganfeng from about 9.6% to about 16.1% on a fully diluted basis, and the 19.99% cap sets a hard ceiling. What the release does not spell out is what happens to the partnership balance if conversion never occurs, which on the stated terms requires the share price to reach $12.50.

On the joint venture, the number a careful reader should hold on to is 33%. Lithium Argentina is the minority partner in PPG, Ganfeng operates it, and while key decisions need both partners, the day to day sits with the majority holder. The funding threshold is the practical constraint: anything above $20 million a year needs joint approval until project level financing is in place, which limits how fast either side can push spending without the other. The partners say they are jointly pursuing project debt and a potential minority strategic investor, so the ownership split disclosed now is not necessarily the one that finances construction.

Two items are worth tracking from public filings. The first is whether the incentive regime application submitted in the first quarter of 2026 is approved on the full 150,000 tpa plan, since the company has tied the expected timing to the end of 2026 and a partial approval would change the fiscal terms of the development. The second is the Cauchari-Olaroz distribution rate. The operation generated $142 million of operating cash flow in the quarter while distributing $16 million, and it is the distributions, not the reported EBITDA, that reach the parent and fund the repayment plan described here.

What the documents say

Lithium Argentina AG (NYSE: LAR) and Ganfeng Lithium Group Co., Ltd. signed definitive agreements on August 24, 2026 to consolidate three adjacent lithium brine projects in Salta province into a single joint venture, and agreed separately that Ganfeng would put $180 million into Lithium Argentina through a convertible note. The Zug based producer, which is also listed in Toronto, will use the money to clear a convertible maturity falling due in January 2027.

The joint venture

The PPG JV brings together Ganfeng’s Pozuelos-Pastos Grandes project and Lithium Argentina’s Pastos Grandes and Sal de la Puna projects as one basin wide development, targeting 150,000 tonnes per annum of lithium carbonate equivalent across three phases on shared infrastructure. The partners put combined historical investment in the projects, including property acquisition and development, at $1.8 billion.

Ganfeng holds 67% and Lithium Argentina 33%. Ganfeng’s team in Salta operates, with a joint technical and financial committee overseeing key decisions, and approval of the development plan, financings and budgets requires both partners. Each funds in proportion to its interest, and annual funding above $20 million needs joint approval until a project level financing is completed. Offtake follows the same proportions.

Completion is expected in September 2026, after which the projects sit under Millennial Lithium B.V., a Dutch holding company owned 67% by Ganfeng and 33% by Lithium Argentina, which will indirectly own all of the Argentine entities holding PPG. An application to Argentina’s incentive regime for large investments, covering the full 150,000 tpa plan, was submitted in the first quarter of 2026, with approval expected by the end of 2026.

The convertible note

The $180 million note is unsecured, carries a 4.0% coupon payable semi annually, and matures six years from issuance in 2032 if not converted or redeemed earlier. It converts at $12.50 per share, which the company describes as a premium of approximately 96% to the five day volume weighted average price of its shares on the New York Stock Exchange for the period ending August 21, 2026.

The company may redeem at par after the first anniversary of issuance if the share price exceeds 130% of the conversion price for 20 trading days within any 30 consecutive trading day period. On a change of control the note may be converted before closing or rolled into the consideration received by common shareholders. Conversion is capped at 19.99% of issued and outstanding shares. The note carries no offtake rights or other commercial arrangements, is transferable only with the company’s consent, is subject to hedging restrictions, and gives Ganfeng a 12 month right to maintain its ownership level.

Ganfeng currently holds about 9.6% of Lithium Argentina’s issued and outstanding common shares. On full conversion it would take 14.4 million additional shares and hold about 16.1% on a fully diluted basis. Closing is expected in September 2026, subject to approvals from the Toronto Stock Exchange and the New York Stock Exchange.

Clearing the January 2027 maturity

The stated use of proceeds is repayment in full of the company’s existing $259 million convertible debt due January 2027. Lithium Argentina ended the second quarter of 2026 with $100 million in cash and equivalents and received a further $27 million in distributions from Cauchari-Olaroz in the third quarter. Concurrent with closing, it will terminate an existing $130 million debt facility, releasing the security and preferential offtake rights attached to it.

Cauchari-Olaroz, in Jujuy province, is the operation funding that position. It is owned 46.7% by Ganfeng, 44.8% by Lithium Argentina and 8.5% by JEMSE, the mining investment company of the Jujuy provincial government, and the company reports its figures on a 100% basis. The operation produced 9,280 tonnes of lithium carbonate in the second quarter of 2026 after a planned maintenance shutdown in May, averaged 95% of design capacity over the first half, and remains on full year guidance of 35,000 to 40,000 tonnes. Revenue was $174 million at an average realised price of about $19,563 per tonne, cost of sales was $63 million, cash operating costs were $5,897 per tonne sold, and adjusted EBITDA was $110 million. Operating cash flow was $142 million. Net debt at the operation fell by $114 million in the quarter after $16 million of distributions to the two partners, and a $170 million debt facility was completed after quarter end.

Stage 2 at Cauchari-Olaroz, which would add 45,000 tpa of capacity, was approved under the Argentine incentive regime in May 2026. The partners are advancing an initial 10,000 tpa modular direct lithium extraction facility as the first phase, with an updated development plan expected around the end of the third quarter of 2026.
