OPERATING AND FINANCIAL HIGHLIGHTS

• As of December 31, 2024, the Company had approximately $594.2 million in cash, cash equivalents and restricted cash.
• During the year ended December 31, 2024, $179.9 million of construction capital costs and other project-related costs were capitalized.
• In the fourth quarter of 2024, the Company provided Bechtel, who is responsible for the engineering, procurement and construction management of Phase 1 (the initial phase of production at Thacker Pass, targeting 40,000 tonnes per year (“t/y”) of battery-grade lithium carbonate), and other major contractors with limited full notice to proceed to de-risk the construction schedule and continue to target completion in late 2027.
• On March 6, 2025, the Company announced a strategic investment of $250 million from fund entities managed by Orion Resource Partners LP (collectively, “Orion”). Orion has committed to purchase senior unsecured convertible notes in the aggregate principal amount of $195 million (the “Notes”) and enter into a Production Payment Agreement (“PPA”) whereby Orion will pay Lithium Americas $25 million in exchange for payments corresponding to the minerals processed and gross revenue generated by Thacker Pass (together, the Notes and PPA represent an aggregate initial investment of $220 million). Orion has also committed, subject to the satisfaction of certain conditions precedent, to purchase an additional $30 million in aggregate principal amount Notes within two years upon request by the Company (the “Delayed Draw Notes”). Together, the Notes, PPA and Delayed Draw Notes represent an aggregate $250 million investment for the development and construction of Phase 1 of Thacker Pass. In addition, Orion has agreed, on a non-binding basis, to evaluate the potential to support up to $500 million of financing for the construction and development of the second phase of production of Thacker Pass targeting an additional 40,000 t/y of battery-grade lithium carbonate of nominal production capacity (“Phase 2”).
• On December 23, 2024, the Company and GM closed a joint venture (“JV”) to fund, develop, construct and operate Thacker Pass for $625 million in total cash and letters of credit, comprised of $430 million of direct cash funding to the JV to support the construction of Phase 1 and a $195 million letter of credit facility. Upon closing of the JV, GM acquired a 38% asset-level ownership stake in Thacker Pass and contributed $330 million of cash into the JV alongside $138 million of cash from Lithium Americas. The remaining $100 million cash contribution from GM and Lithium Americas’ $192 million cash contribution, is to be contributed to the JV when the final investment decision (“FID”) for Phase 1 is declared.
• On October 28, 2024, the Company and the U.S. Department of Energy’s (“DOE”) Loan Programs Office closed a $2.26 billion loan under the Advanced Technology Vehicles Manufacturing Loan Program (the “DOE Loan”) for financing the construction of the processing facilities for Phase 1 of Thacker Pass. The Company currently expects to make the first draw on the DOE Loan sometime in the third quarter of 2025. Remaining conditions precedent to first draw include a project finance model bring down.
• Together with the DOE Loan and the investments from both GM and Orion, Lithium Americas expects to achieve fully funded status at the project and corporate level for the development and construction of Phase 1 of Thacker Pass for the duration of construction.
• In August 2024, the Company received approval for a $11.8 million grant from the U.S. Department of Defense to support an upgrade of the local power infrastructure and to help build a transloading facility.
• On April 22, 2024, the Company completed an underwritten public offering (the “Offering”) of 55 million common shares at a price of $5.00 per common share for aggregate gross proceeds to the Company of $275 million. Net proceeds from the Offering were approximately $262 million and will be used to fund the advancement of construction and development of Thacker Pass.

  • The contract for the module erection and camp operations scope of work was awarded in February 2025.
  • First occupancy of the Workforce Hub is targeted for the second half 2025.
• On January 7, 2025, the Company announced an increased mineral resource (“Resource”) and mineral reserve (“Reserve”) estimate for Thacker Pass, including the release of an independent National Instrument 43-101 technical report (“NI 43-101 Technical Report”) entitled “NI 43-101 Technical Report on the Thacker Pass Project Humboldt County, Nevada, USA,” and an independent S-K 1300 technical report (the “S-K 1300 Technical Report”, together with the NI 43-101 Technical Report, the “Technical Reports”) entitled “S-K 1300 Technical Report on the Thacker Pass Project Humboldt County, Nevada, USA,” both dated effective December 31, 2024.
  • The NI 43-101 Technical Report includes a Proven and Probable Reserve estimate of 14.3 million tonnes (“Mt”) of lithium carbonate equivalent (“LCE”) at an average grade of 2,540 parts per million (“ppm”) lithium (“Li”) and a Measured and Indicated Resource estimate of 44.5 Mt LCE at an average grade of 2,230 ppm Li.
  • The Reserve estimate supports an expansion plan of up to five phases targeting total nominal production capacity of 160,000 t/y of battery-quality lithium carbonate with an 85-year mine life.

TECHNICAL INFORMATION

The scientific and technical information in this news release has been reviewed and approved by Rene LeBlanc, PhD, SME, Vice President, Growth and Product Strategy of the Company, and a “qualified person” as defined under National Instrument 43-101 and Subpart 1300 of Regulation S-K under the United States Securities Act of 1933.

FINANCIALS

Selected consolidated financial information is presented as follows:

During the year ended December 31, 2024, there was an increase in net loss from the year ended December 31, 2023, which was mainly due to higher transaction costs related to advancing and closing both the DOE Loan and JV and the recognition of a loss on the fair value of financial instruments compared with a gain in the comparable year, partially offset by higher interest earned on increased cash balances in 2024.

At December 31, 2024, total assets increased primarily due to cash received upon closing of the Offering and the JV. Mineral properties, plant and equipment increased due to the capitalization of Thacker Pass construction costs for the full year, including engineering, earthworks and the shipping and delivery of the final WFH modules.
