- As of August 12, 2026, the Company had 363,042,943 shares issued and outstanding.
The Company continues to progress major construction of the processing plant at Thacker Pass Phase 1, targeting mechanical completion in late 2027. As of June 30, 2026:
- 3.42 million workhours were completed without a serious injury or lost-time incident, with a total recordable incident frequency rate of 0.58.
- $1.8 billion of construction capital and other project-related costs had been capitalized, of which $1.6 billion is part of the total capital expenditure ("Capex") estimate of $2.93 billion per the Company’s Technical Report entitled "NI 43-101 Technical Report on the Thacker Pass Project Humboldt County, Nevada, USA," effective December 31, 2024 ("Technical Report"). The Company continues to target a total Capex range of $1.3 billion to $1.6 billion for Thacker Pass Phase 1 for fiscal year 2026. See Capital Expenditure and 2026 Capex Guidance below for details.
- Detailed engineering design completed surpassed 95%, while procurement exceeded 80%, including the shipment of major plant materials and equipment.
- Over 1,600 personnel were on site, and on-site personnel levels are expected to increase to over 2,000 in the second half of 2026.
- Over 1,500 workers were residing at the Company’s all-inclusive housing facility in Winnemucca (the "Workforce Hub" or "WFH").
Long-lead equipment continued arriving at Thacker Pass and the fabrication yard in Winnemucca. Outstanding long-lead items are expected to be delivered throughout 2026, along with other equipment and construction materials.
- Over 85% of the structural steel for Thacker Pass, which is sourced from the United Arab Emirates, is in transit or has arrived on site at Thacker Pass or the laydown yard in Winnemucca. The balance is expected in Q3 2026. The Company and Bechtel have worked with the steel supplier to minimize the impact of the Middle East conflict, including the closure of the Strait of Hormuz, on the fabrication and shipment of steel to Thacker Pass. The Company has successfully re-routed steel through the Port of Jeddah.
Development milestones achieved at Thacker Pass during Q2 2026 include:
- Completing upgrades to the high voltage power line connecting Thacker Pass to the local power grid.
- Placement of the first Electrical Room, 115kV Power Transformer and Control Enclosures.
- Progressing structural steel at the Filter Building, Magnesium Sulfate Building and the Lithium Carbonate Building.
- Deliveries of approximately 100 prefabricated pipe rack modules, with pre-installed piping manufactured in Winnemucca. Deliveries are expected to continue throughout Q3 2026.
- Commencement and continuation of key equipment installation at the following facilities:
  - Lithium Carbonate Crystallizer: Bicarbonate Reactor;
  - Magnesium Sulfate Building: Turbo Fans, Stage 4 Crystallizer;
  - Filter Building: Air Compressors and Receivers, Conveyor Tail Pulleys, Neutralization Filter Discharge Conveyors;
  - Countercurrent Decantation and Run-of-Mine areas: Thickener Steel and Shell Plates;
  - Sulfuric Acid Plant: Fin Fan Coolers, SS Converter, Steam Turbine Generator, Main Compressor, Cold Interpass Heat Exchanger, Hot Interpass Heat Exchanger and the 198-foot-tall Duplex Plant Stack.
The following are expected development milestones for the second half of 2026:
- All main concrete required at the site is expected to be completed.
- Early commissioning of utilities in the individual plants is expected to commence.
- Given the advanced level of detailed engineering achieved, the Company has commenced a definitive capital estimate, targeting completion by the end of Q3 2026. Advanced engineering and procurement is expected to enable the team to estimate remaining quantities and materials with higher confidence. The Company will use current data to assess remaining labor needs and productivity rates for the estimate and will incorporate recent and unexpected developments, including implications from tariffs, conflicts in the Middle East, fuel prices, and other inflationary increases not included in the total Capex estimate of $2.93 billion per the Company’s Technical Report. During Q2 2026, the cost environment for activities associated with Thacker Pass was also unfavorably impacted by items such as: reduced open sea lane availability, reductions in the availability of U.S. fabrication capacity, constraints in U.S. logistics, further inflationary pressures as well as an increasingly competitive skilled labor market. Further, total associated tariff exposure, the majority of which is expected to be incurred during 2026, is estimated between $80 million and $100 million.
Construction at the Company’s Transload Terminal ("TLT") west of Winnemucca continues. In Q2 2026, the general site and railroad grading were completed and installation of rail stabilization (geo-membrane) and sub-ballast commenced. Completion of the TLT is targeted in 2027 to align with startup at Thacker Pass. The TLT is approximately 60 miles from Thacker Pass, adjacent to the rail line, and is intended to support operations by serving as a critical logistics hub for the operation’s reagents.
During Q2 2026, the Company delivered a $5.0 million commitment to the Fort McDermitt Paiute and Shoshone Tribe’s Building Fund, in accordance with its obligations under the Community Benefits Agreement. The funds will support plans to rebuild a Travel Plaza, which was lost to fire in September 2020. An additional $0.4 million has been contributed to the tribe for workforce training, cultural monitoring and administrative purposes.

CAPITAL EXPENDITURE AND 2026 CAPEX GUIDANCE

Loss on financial instruments measured at fair value		(4.7	)		(2.2	)		(2.5	)
Other income		13.3			2.7			10.6

General and administrative expenses increased to $26.2 million in YTD Q2 2026 (YTD Q2 2025 - $14.4 million) due to increased hiring, share-based compensation, community investment, and regulatory and professional fees supporting expanded operations.

Transaction costs decreased to $1.0 million in YTD Q2 2026 (YTD Q2 2025 - $17.6 million). YTD Q2 2026 costs primarily related to advisory and professional fees for the warrants the Company issued to the DOE to purchase up to 18,268,687 common shares ("LAC Warrant") and the warrants the JV issued to the DOE to purchase 8,656,509,695 non-voting units of the JV ("JV Warrant") issuances on January 30, 2026, while YTD Q2 2025 costs primarily related to Orion’s $250 million strategic investment (the "Orion Investment") and advisory fees due upon achieving the final investment decision ("FID") for Thacker Pass Phase 1.

The LAC Warrant and the JV Warrant were initially recognized as financial liabilities on October 7, 2025. A $5.0 million loss on change in fair value of the LAC Warrant was recognized in YTD Q2 2026 (YTD Q2 2025 - $nil), reflecting the increase in the Company’s share price from $4.36 on December 31, 2025 to $4.87 on January 30, 2026, when the LAC Warrant was issued and reclassified to equity. A $9.9 million gain on change in fair value of the JV Warrant, including obligations under the Put, Call and Exchange Agreement, was recognized in YTD Q2 2026 (YTD Q2 2025 - $nil), primarily reflecting the decrease in share price from $4.36 on December 31, 2025 to $3.85 on June 30, 2026.

A $20.0 million gain on change in fair value of the embedded derivative associated with the Notes (the "Embedded Derivative") was recognized in YTD Q2 2026 (YTD Q2 2025 - $6.8 million), primarily reflecting the decrease in the Company’s share price from $4.36 at December 31, 2025 to $3.85 at June 30, 2026.

A $4.7 million loss on financial instruments measured at fair value was recognized in YTD Q2 2026 (YTD Q2 2025 - $2.2 million), primarily consisting of a $4.5 million loss on change in fair value of the Company’s investment in Ascend Elements, Inc. ("Ascend Elements") (YTD Q2 2025 - $1.8 million loss). During YTD Q2 2026, the Company determined the fair value of the Ascend Elements investment was $nil based on public disclosures indicating significant uncertainty regarding recovery.

Other income for YTD Q2 2026 increased to $13.3 million (YTD Q2 2025 - $2.7 million), primarily due to higher interest income from increased balances in interest-generating bank accounts, driven largely by proceeds from the Company’s ATM programs.

The Three Months Ended June 30, 2026 Compared with the Three Months Ended June 30, 2025

The following table provides a summary of the Company’s unaudited condensed consolidated interim statements of income (loss) for Q2 2026 compared with the three months ended June 30, 2025 ("Q2 2025").

Selected Financial Position Information

(in US$ millions)	June 30, 2026		December 31, 2025		Change
Cash and restricted cash	$	1,279.2	$	905.6	$	373.6
Mineral properties, plant and equipment, net		2,090.8		1,344.0		746.8
Total assets		3,535.9		2,579.0		956.9
Total liabilities		1,586.3		992.4		593.9

At June 30, 2026, total assets increased by $956.9 million from December 31, 2025, driven primarily by a $373.6 million increase in cash and restricted cash and a $746.8 million net increase in mineral properties, plant and equipment, partially offset by a $157.2 million decrease in deferred financing costs.

Cash and restricted cash increased primarily from DOE Loan advances and proceeds from the Company’s ATM programs, partially offset mainly by cash outflows related to Thacker Pass construction costs, general and administrative expenses, and transaction costs. DOE Loan advances are held in restricted bank accounts owned by Lithium Nevada LLC ("LN", a wholly owned subsidiary of Lithium Nevada Ventures LLC ("Lithium Nevada Ventures")), the JV between General Motors Holdings LLC ("GM") and the Company (together, the "JV Partners"), and managed by a collateral agent.
Mineral properties, plant and equipment, net increased mainly due to continued development of Thacker Pass, including costs associated with completion of the WFH, on-going engineering and procurement activities, payments towards long-lead equipment as well as continued on-site construction works. In addition, in YTD Q2 2026, finance costs, related to Thacker Pass totaling $32.7 million including interest on the Orion Investment and DOE Loan advances, were capitalized.
Deferred financing costs decreased due to reclassification of $157.2 million in unamortized costs related to the second and third DOE Loan advances. Upon signing the omnibus waiver, consent and amendment (the "OWCA") entered into by the Company and the DOE on October 7, 2025, $400.2 million in transaction costs were recorded as an asset. As funds are advanced, these costs are allocated to the DOE Loan liability proportionally and amortized as interest over the loan term using the effective interest method, then capitalized to Thacker Pass.

At June 30, 2026, total liabilities increased by $593.9 million compared to December 31, 2025, primarily driven by the following:

a $637.0 million increase in the DOE Loan, reflecting advances of $774.0 million and $17.4 million of interest costs, net of $157.2 million of amortized deferred financing costs; and
an $83.8 million decrease in the LAC Warrant obligation, reflecting the $88.8 million fair value reclassified to equity on January 30, 2026, partly offset by a $5.0 million loss recognized for the fair value increase from December 31, 2025 to January 30, 2026.
