Lithium Americas Reports Second Quarter 2025 Results

(All amounts in US$ unless otherwise indicated)

Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) (" Lithium Americas " or the " Company ") announced that it has filed its Quarterly Report on Form 10-Q, which includes the Company's consolidated interim financial statements (" Financials ") for the three and six months ended June 30, 2025 (" Q2 2025 "), and provided an update on its Thacker Pass lithium project in Humboldt County, Nevada (" Thacker Pass " or the " Project ").

Jonathan Evans, President and Chief Executive Officer of Lithium Americas said, "Major construction is progressing well at Thacker Pass and there is excitement amongst our employees, stakeholders and partners. We continue to focus on de-risking both the project schedule and capital costs. Our teams continue to work toward limiting the effect of any potential tariff or trade disputes on our construction supply chain. We continue to target mechanical completion of Phase 1 in late 2027."

"Thacker Pass is undergoing noticeable growth every week, and we now have over 300 workers on site. The processing plant area is materializing with the placement of permanent concrete foundations and facility entrances, and building of permanent roads is underway throughout the site. The first shipment of steel arrived in Winnemucca in late July and we expect to begin first steel installation in September. We are excited to see the processing facilities start to take shape and look forward to manufacturing a major source of U.S.-lithium to meet domestic needs," added Mr. Evans.

Q2 2025 PROJECT AND CONSTRUCTION HIGHLIGHTS

• On April 1, 2025, the Company and General Motors Holdings LLC (" GM ") (together, the " Joint Venture (JV) Partners ") announced the final investment decision (" FID ") for construction of Phase 1 of Thacker Pass.
  
• During the quarter ended June 30, 2025, $124.8 million of construction capital costs and other project-related costs were capitalized. As of June 30, 2025, a total of $574.1 million of construction capital costs and other project-related costs have been capitalized.
  
• The Company has resolved or secured judicial dismissal of all legal and regulatory actions and proceedings, which arose in the ordinary course of resource development. Those resolutions did not materially impact the Company's financial position or construction schedule. The Company continues to progress major construction at Thacker Pass. Completion of Phase 1 of Thacker Pass is targeted for late 2027.
  
• Project engineering and procurement continue materially in line with the Project schedule to support construction.
  
  • As of June 30, 2025, detailed engineering is approximately 70% design complete and expected to increase to over 90% design complete by year end 2025. The higher level of detailed engineering at the early stages of construction helps to de-risk execution in terms of Project schedule and cost.
    
  • In April 2025, fabrication of the structural steel to be used to build the facilities at Thacker Pass commenced. First steel installation is targeted to commence in September 2025.
    
  • Manufacturing of long-lead equipment continues to advance with expected delivery in line with the Project schedule.
    
  • The Company has entered into certain long-term purchase agreements related to long-lead equipment, infrastructure and services related to the construction of the processing plant as well as development and mining services at Thacker Pass. To date, approximately $425 million has been committed.
    
• Major construction at Thacker Pass is progressing, with permanent concrete placement in the processing plant area commencing in early May 2025. Activity at site is focused on key areas to enable peak construction, which is expected in 2026. As of June 30, 2025:
  
  • There were approximately 300 manual craft workers on site, which is expected to increase to approximately 1,000 workers by year end 2025. At peak construction, approximately 1,800 workers are expected on site.
    
  • Structural excavation was underway to support the buildout of facilities and structural elements such as pipe racks.
    
  • Foundation preparation and rebar for concrete for the processing plant facilities continued to progress.
    
  • Construction of permanent roads and entrances to the processing plant facilities were underway.
    
  • Worker break tents were nearing completion.
    
• Placement of housing modules at the Company's all-inclusive housing facility for construction workers in Winnemucca (the " Workforce Hub " or " WFH ") is well advanced. Mechanical, electrical and plumbing work is progressing, with first occupancy targeted for the second half of 2025. The completion of the WFH will enable ramp-up in the number of construction workers at site.

Q2 2025 FINANCIAL AND CORPORATE HIGHLIGHTS

• As of June 30, 2025, the Company had $509.1 million in cash and restricted cash.
  
  • On April 1, 2025, the Company closed the previously announced strategic investment from fund entities managed by Orion Resource Partners LP (collectively, " Orion "), for the development and construction of Phase 1 of Thacker Pass (" Orion Investment "). As part of closing, Orion paid the Company total gross proceeds of $220 million in cash for $195 million of senior unsecured convertible notes (the " Notes ") and $25 million in exchange for payments corresponding to the minerals produced and gross revenue generated by Thacker Pass (the " Production Payment Agreement " or " PPA ").
    
  • On declaring FID, GM and the Company contributed $100 million and $191.6 million in cash to the JV, respectively.
    
• On May 15, 2025, the Company established an at-the-market equity program (" ATM Program ") pursuant to which the Company may sell its common shares, no par value, for up to a maximum aggregate $100 million and intends to use the net proceeds for general corporate purposes, which may include funding of corporate and project overhead expenses, financing of capital expenditures, repayment of indebtedness and additions to working capital.
  
  • As of June 30, 2025, the Company issued and sold 3.361 million common shares at an average price of $2.76 per share pursuant to the ATM Program, for aggregate net proceeds of $8.5 million after sales agent's commission and other expenses. Subsequent to June 30, 2025, the Company issued and sold 18.103 million common shares at an average price of $3.11 per share pursuant to the ATM Program, for aggregate net proceeds of $55.1 million after sales agent's commission and other expenses.
    
• The Company currently expects to make the first draw on the previously announced $2.26 billion loan from the Department of Energy (" DOE " / the " DOE Loan ") sometime in the second half of 2025.
  
  • In advance of first draw, GM has released to the Company the previously announced $195 million letter of credit facility that can be used as collateral to support reserve account requirements under the DOE Loan.
    
• On July 29, 2025, the Company published an environment, social, governance and safety (" ESG-S ") report, themed "Driving Partnerships to Create Value," available on the Company's website. The report includes sustainability performance and progress activities for the period January 1 to December 31, 2024 at the corporate level, Thacker Pass, WFH, Lithium Technical Development Center and the Company's office locations.

FINANCIALS

Selected consolidated financial information is presented as follows:

During the six months ended June 30, 2025, net loss increased compared with the net loss for the comparable year-earlier period primarily due to higher transaction costs associated with closing the Orion Investment and advisory fees due upon achieving FID, partially offset by a gain on financial instruments measured at fair value in Q2 2025 compared with a loss on financial instruments measured at fair value in Q2 2024.

At June 30, 2025, total assets increased due mainly to proceeds received pursuant to the Orion Investment, contributions made to the JV by GM upon declaring FID, which was partially offset by payment of accrued liabilities recognized at December 31, 2024, as well as cash used to fund operating costs in the six months ended June 30, 2025. Total liabilities increased mainly due to amounts associated with the Orion Investment which were non-current at June 30, 2025.
