LITHIUM AMERICAS CORP. (LAC) stock intrinsic value fair value estimate & owner earnings analysis

Lithium Americas is building Phase 1 of the Thacker Pass lithium mine and chemical plant in Nevada. Phase 1 is designed to make 40,000 tonnes a year of battery-grade lithium carbonate. The company has no revenue and none is expected until production ramps up in 2028 (mechanical completion is targeted for late 2027). It owns 62% of the joint venture that holds the project; General Motors owns 38% and has agreed to buy up to all Phase 1 output for 20 years at a price tied to market lithium prices. Because there are no operating earnings yet, the value here comes from what the plant can earn once built, less what is still to be spent and what is owed. What we credited. Only Phase 1, which is under construction and financed: about $1.76 billion has been spent since 2023, the US Department of Energy loan (about $2.23 billion including capitalized interest, fixed at Treasury rates with no credit spread, roughly 23 years) is being drawn, and cash of about $0.82 billion plus $0.46 billion of restricted cash sat on the balance sheet at June 30, 2026. We left out Phases 2 to 4 in the company's technical report (no capital committed), any lithium price recovery, and any operating record we cannot yet see. The company's own $24,000-per-tonne price assumption was not used. Instead we priced lithium carbonate within the range it has actually traded over the last decade from public market history (a source outside the filings, used only for history): $10,000, $12,000 and $17,000 per tonne in the three cases, held flat with costs. Operating costs use the technical report's $6,238 per tonne average as a starting point, with a higher cost in the early ramp-up years. Base case. The plant reaches about 85% of nameplate (34,000 tonnes) at $12,000 per tonne with costs of about $7,000 per tonne, and runs for 30 years, after which we assume nothing. Construction costs run about 5% over the $2.93 billion estimate. The operating years are worth about $1.65 billion today against roughly $1.4 billion still to spend, so the business is worth about $0.25 billion. Adding cash net of the $1.11 billion of debt drawn (including $110 million of 9.875% convertible notes) and a credit for the DOE loan's below-6% rate gives about $0.57 billion for the joint venture. The company's roughly 59% share (after the 5% economic interest issued to the DOE), less about $0.25 billion of corporate costs, leaves roughly $0.09 billion, or about $0.23 per share on about 381 million diluted shares. Bear case. Lithium carbonate averages $10,000 per tonne, the plant reaches only 75% of nameplate at about $7,500 per tonne, and construction costs run 10% over budget. The plant then makes only about $50 million a year against $1.5 billion left to spend, so the business is worth about negative $1.0 billion, and after cash, debt and the company's share the value is about negative $1.42 per share. In this case the company appears to owe more than it is worth, by roughly $0.5 billion in total. The company has guaranteed completion costs and the full DOE loan as co-borrower, and overruns fall on the owners. Bull case. Lithium carbonate averages $17,000 per tonne, the plant reaches full 40,000-tonne capacity at about $6,300 per tonne, and construction finishes on budget. Operating years are worth about $4.0 billion against $1.26 billion still to spend, so the business is worth about $2.8 billion; after net cash, cheap DOE debt and conversion of the notes, the company's share is about $1.6 billion, or about $3.97 per share on about 410 million shares. Other items that affect the outcome. The DOE received warrants in January 2026 for 5% of the company's shares at $0.01 and 5% of the joint venture, which we have counted. The DOE deferred $184 million of early debt payments, and the company must add $120 million to loan reserve accounts within a year of October 2025. Orion, the lender behind the convertible notes, is also owed 0.96% of gross revenue in perpetuity. Distributions from the joint venture are restricted until the plant is complete and has paid the DOE for four consecutive quarters, so no cash to shareholders is credited near term. The company plans a definitive capital estimate in the first half of 2026, and the construction manager is paid on a cost-reimbursable basis, so cost risk sits with the owners. Steel supply from the United Arab Emirates and tariffs are named risks. How this could be wrong. The value is extremely sensitive to the lithium price: at $12,000 versus $17,000 per tonne the per-share value moves from about $0.23 to about $4. Nothing yet proves the plant will reach its design output, since this clay-based process has only been tested at pilot scale. Reported profit in early 2026 came from non-operating items, not operations, and does not change this view. Historical owner earnings were negative in every year (about $(0.23), $(0.18) and $(0.30) per share for 2023 to 2025) because the company is funding construction, so no earnings level was used as a starting point.
