Standard Lithium Reports Third Quarter 2025 Results
• Released positive Definitive Feasibility Study (“DFS”) for the South West Arkansas Project (“SWA Project”) which
continues progressing towards a Final Investment Decision (“FID”)
• Announced Maiden Inferred Resource for the Company’s first project in East Texas (“Franklin Project”) containing the
highest reported lithium-in-brine grades in North America
• Completed upsized $130 million follow-on offering on the back of strong institutional investor demand and an
oversubscribed order book, following quarter close
VANCOUVER, British Columbia, Nov. 10, 2025 -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLI)
(NYSE.A: SLI), a leading near-commercial lithium company, today announced its financial and operating results for the three
and nine-month periods ended September 30, 2025.
“We had a busy and productive third quarter as we successfully executed on multiple key milestones that we had set out to
achieve,” said David Park, Chief Executive Officer and Director of Standard Lithium. “We released a Definitive Feasibility Study
for the SWA Project, highlighting the attractiveness and cost-competitiveness of our first commercial project. We also
released a Maiden Inferred Resource for our first project in East Texas, the Franklin Project. With some of the highest
reported lithium-in-brine grades in North America, it provides a strong foundation for future scalable production in the
Smackover as we expand our portfolio of high-quality lithium assets.”
“Following quarter close, we took a further de-risking step by completing a capital raise, supported by strong investor demand,
that will put us in a position to reach FID at SWA, as well as progress our Franklin and other projects in East Texas.”
“Looking ahead, we expect to provide multiple updates in the coming months as we seek to conclude our ongoing project
financing and customer offtake processes, finalize selection of our key SWA Project vendors and approve FID before
beginning construction at SWA in 2026.”

• Standard Lithium Closes Upsized $130 Million Underwritten Public Follow-on Equity Offering
Closed an underwritten public offering on October 20 th of 29,885,057 common shares at a price of $4.35 per common
share for aggregate gross proceeds of approximately $130 million. Strong support received from institutional investors
allowed the Company to increase the original transaction size by an additional $10 million.
• Smackover Lithium Files DFS for Its SWA Project, North America's Highest-Grade Reported Lithium Brine
Reserve
Filed on October 14 th following release of the DFS highlights during the third quarter. The SWA Project contemplates
initial production capacity of 22,500 tonnes per annum of battery-quality lithium carbonate, producing 447,000 tonnes
(Proven Reserves) of lithium carbonate equivalent (“LCE”), or 38% of the in-situ Measured and Indicated Resources of
1,177,000 tonnes LCE. The SWA Project will begin production at an average lithium concentration of 549 mg/L and will
process 0.20 km 3 of brine over its modelled 20-year life at an average lithium concentration of 481 mg/L.
• Smackover Lithium Files Maiden Inferred Resource for its Franklin Project in East Texas, Containing the
Highest Reported Lithium-in-Brine Grades in North America
Filed on November 5 th following release of the highlights during the third quarter. This report for Smackover Lithium’s
first of three planned projects in the East Texas region of the Smackover highlights the size and quality of its brine
position. It marks a key step towards the ultimate goal of reaching production of over 100,000 tonnes of lithium
chemicals per year in Texas through multiple phases.
• Smackover Lithium Receives Key Final Integration Approval from the Arkansas Oil and Gas Commission
(“AOGC”) for SWA Project
Received unanimous approval from the AOGC for its Integration Application for the Reynolds Brine Unit where the initial
commercial phase of the SWA Project is planned to be developed. Integration is the formal process which
amalgamates any non-leased mineral interests into an approved brine production unit, ensuring the operator’s access
to the brine while protecting the correlative rights of mineral owners, and is a key de-risking step providing certainty on
the resource.
Highlights From Three-Month Period Ended September 30, 2025
• Smackover Lithium Announces Positive Definitive Feasibility Study Results for its South West Arkansas
Project
Highlighted by a 20.2% unlevered pre-tax internal rate of return (“IRR”), with competitive average cash operating costs of
$4,516/t and all-in costs of $5,924/t over the operating life, an all-in Class III capex estimate of $1.45 billion including a
12.3% contingency, and an upgraded mineral resource. The principal recommendation from the DFS is that the Project
is ready to progress to an FID. Construction is expected to commence in 2026 shortly after FID, with first production
targeted in 2028.
• Smackover Lithium Releases Maiden Inferred Resource for its Franklin Project Comprising a Portion of
Significant Brine Position in East Texas
Highlighted by 2.2M tonnes of LCE at an average lithium grade of 668 mg/L, 15.4M tonnes of potash (as potassium
chloride) - a newly added mineral to the U.S. Geological Survey 2025 Draft Critical Mineral List - and 2.6M tonnes of
bromide at the inferred resource category. It contains the highest reported lithium-in-brine grades in North America.
• Smackover Lithium Reports Highest Lithium Brine Grade in SWA Project Area
Smackover Lithium completed sampling from its newest exploration well, the Lester well, in the SWA Project area. One
sample recorded the highest lithium concentration reported to date from the SWA Project area: 616 mg/L lithium in
brine, while average lithium concentration in brine from the Lester well was 582 mg/L. This concluded all sub-surface
exploration activities for Phase 1 of the SWA Project.
• Aquatech Acquires Koch Technology Solutions' Direct Lithium Extraction Business
On September 16th, Aquatech announced the acquisition of a portion of Koch Technology Solution’s (“Koch”) business,

Use of Non-GAAP Measures
Certain financial measures referred to in this news release are not measures recognized under International Financial
Reporting Standards (“ IFRS”) and are referred to as non-GAAP financial measures or ratios. These measures have no
standardized meaning under IFRS and may not be comparable to similar measures presented by other companies. The
definitions established and calculations performed are based on management’s reasonable judgement and are consistently
applied. These measures are intended to provide additional information and should not be considered in isolation or as a
substitute for measures prepared in accordance with IFRS.
The non-GAAP financial measures used in this news release are common to the mining industry. All-in operating cost per
tonne is a non-GAAP financial measure or ratio and has no standardized meaning under IFRS Accounting Standards and may
not be comparable to similar measures used by other issuers. As the SWA Project is not in production, the Company does
not have historical non-GAAP financial measures nor historical comparable measures under IFRS, and therefore the foregoing
prospective non-GAAP financial measures may not be reconciled to the nearest comparable measures under IFRS.
