-- 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 (GLOBE NEWSWIRE) -- 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."
Highlights Subsequent to the Three-Month Period Ended September 30, 2025
All amounts are in US dollars unless otherwise indicated. All terms not otherwise defined have the meaning given to them under the CIM Definition Standards for mineral resources and mineral reserves.
-- Standard Lithium Closes Upsized $130 Million Underwritten Public
Follow-on Equity OfferingClosed an underwritten public offering on
October 20th 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 ReserveFiled on October 14th
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 km3 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 AmericaFiled on November 5th 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 ProjectReceived
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 ProjectHighlighted 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
TexasHighlighted 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
AreaSmackover 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
BusinessOn September 16th, Aquatech announced the acquisition of a
portion of Koch Technology Solution's ("Koch") business, including the

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.

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.
