Lithium Americas Provides a Project Update and 2026 Capex Guidance for

Thacker Pass

(All amounts in US$ unless otherwise indicated)

VANCOUVER, British Columbia--(BUSINESS WIRE)--February 19, 2026--Lithium Americas

Corp. (TSX: LAC) (NYSE: LAC) (“Lithium Americas” or the “Company”) provides a project

update for the year ended December 31, 2025, 2026 capital expenditure (“Capex”) guidance and

2026 project development milestones for its Thacker Pass project in Humboldt County, Nevada

(“Thacker Pass” or the “Project”).

“2025 was a pivotal year for Lithium Americas and the Thacker Pass Project with Phase 1

construction well underway,” said Jonathan Evans, President and Chief Executive Officer of

Lithium Americas. “Safety remains our top priority, processing facilities are rising and critical

equipment and materials are arriving daily. As planned, we expect to reach peak construction

employment of roughly 1,800 skilled craftspeople by year-end. Lithium market conditions are

strengthening just as the project prepares to come online in late 2027, with full ramp-up through

2028.”

Mr. Evans added, “Thacker Pass represents a unique opportunity to build a secure, resilient

North American lithium supply chain. We value our partnership with the federal government and

the support of local, state and federal leaders who share our commitment to strengthening

America’s energy future.”

Q4 2025 PROJECT AND CONSTRUCTION HIGHLIGHTS

The Company continues to progress major construction at Thacker Pass Phase 1. Construction

milestones achieved in Q4 2025 include:

 As of December 31, 2025, detailed engineering design complete achieved 93%, while

procurement was 60% complete.

 At the end of December 2025, there were approximately 950 personnel on site at Thacker

Pass, including approximately 740 manual craft and 210 additional site workers. The

number of personnel is expected to increase to approximately 1,800 at peak construction

in 2026.

 In 2025, 1.69 million workhours were completed at Thacker Pass without a serious injury

or lost-time incident, and the total recordable incident frequency rate was 0.21.

 Foundation, rebar and concrete work continue at multiple facilities throughout the

processing plant, including the Filter Building, the Magnesium Sulfate Building and

Warehouse Facilities.

 Multiple facilities at the Thacker Pass processing plant also progressed structural steel

installation, including the Filter Building, Magnesium Sulfate Building and the Liquid

Sulfur Tanks.

 The installation of certain long lead equipment commenced in Q4 2025.

 Active hydroseeding of disturbed areas across the site using native seeds was performed.

 In September 2025, the Workforce Hub (“WFH”) became partially operational and

welcomed its first residents. As of February 13, 2026, there were nearly 700 residents at

the WFH. Occupancy at the WFH is expected to align with the hiring and ramp-up of

construction workers.

The Company is growing its Operations and Business Readiness (“OBR”) team to de-risk the

transition from the engineering, procurement and construction phases of Thacker Pass through

commissioning, ramp up and into production and maintenance of the greenfield mining and

chemical facility.

 As of December 31, 2025, the OBR team had 25 employees. Hiring additional OBR team

members is expected to ramp up throughout 2026 in preparation for pre-commissioning

and process commissioning in late 2026 and throughout 2027.

 Throughout 2025, the following key roles were filled: Site Operations Director, Lithium

Carbonate Plant Manager, Sulfuric Acid Plant Manager, Maintenance Manager, Supply

Chain Manager, Training Manager and Process Superintendent.

 The OBR team is currently preparing safety plans, operating procedures, multi-

disciplinary training programs, emergency response training and other programs, which

are being finalized and implemented.

 The OBR team continues to conduct factory acceptance tests of key equipment and

processes, while working with these vendors to learn best practices from their customers’

existing operations.

2026 CAPITAL EXPENDITURE GUIDANCE

The Company is targeting a Capex range of $1.3 billion to $1.6 billion for Thacker Pass Phase 1

for fiscal year 2026, as shown in the table below:

(US$) 2026 Capex Guidance

Thacker Pass Phase 1 construction costs (1)(2) $1.2 - $1.5 billion

Other capitalized development costs for Thacker Pass (3) $30 - $40 million

Capitalized interest on the DOE loan $45 - $55 million

Total $1.3 - $1.6 billion

2026 Capex Guidance Notes:

(1) Thacker Pass Phase 1 construction costs do not include $8.0 million of community contributions that are

required to be expensed under US GAAP, though these were included in the $2.93 billion Capex estimate 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”).

(2) Thacker Pass Phase 1 construction costs include estimated tariff exposure for equipment and construction

material sourced from Canada, China, India, UAE, Turkey and the European Union. The Company has been

working toward limiting the effect of any potential tariffs on our construction supply chain, with approximately

75% of the total capital project cost structure related to labor, contractors and other services not expected to be

directly affected by any potential tariffs. The Company continues to monitor closely potential tariff exposure;

however, changes in tariffs and trade restrictions can be announced with little or no advance notice. The

estimates provided are based on known information as of the date of this news release.

(3) Other capitalized development costs are required to be capitalized under US GAAP, though these were not

included in $2.93 billion Capex estimate per the Company’s Technical Report.

Fiscal year 2025 Capex spend is expected to be disclosed in the Company’s Annual Report on

Form 10-K for the year ended December 31, 2025, which is expected to be filed on March 19,

2026.

EXPECTED 2026 DEVELOPMENT MILESTONES

The Company continues to target mechanical completion of the Thacker Pass Phase 1 processing

plant in late 2027. Following are expected development milestones for 2026:

 Major long-lead equipment and a substantial amount of other equipment and construction

materials are expected to be delivered to either Thacker Pass or the fabrication yard in

Winnemucca throughout the first half of 2026, including the steam turbine generator,

sulfuric acid plant stacks and cold interpass heat exchanger.

 In early January 2026, the first of nearly 100 completed pipe rack modules were

delivered to site. They were fabricated offsite to reduce labor hours and facilitate

enhanced safety performance. Once delivered to site, the interlocking modules (with pipe,

cable trays already installed) will be placed and joined together at the processing plant.

The remaining pipe rack modules are expected to be delivered to site by mid-year.

 The first cable pulls on the module pipe racks are targeted to commence in spring 2026.

 Commissioning of the high voltage power line is targeted to commence in Q2 2026.

 Given the advanced level of detailed engineering, the Company is expected to begin a

definitive capital estimate in the first half of 2026. Advanced levels of engineering and

procurement will enable the team to estimate quantities and materials with higher

confidence. Further assessment of labor availability and productivity rates is expected to

occur by the fourth quarter of 2026.

 All main concrete required at site is expected to be completed in Q3 2026.

 Early commissioning of the individual plants is expected to commence in Q4 2026.

 As part of the Project, the Company is upgrading six regional substations and switching

stations to enhance reliability for grid power from the local electric utility cooperative.

This work is expected to be completed to help energize the Project in Q4 2026.
