Standard Lithium Ltd.’s SEC filings document the disclosures of a Canadian foreign private issuer developing U.S. lithium brine assets. The company’s Form 6-K reports include press releases, material change reports, and exhibits covering quarterly and annual results, the South West Arkansas Project, East Texas properties, the Arkansas demonstration plant, direct lithium extraction operations, and Smackover Lithium joint venture agreements.
Filings also disclose capital-structure activity, including common share issuances under the at-the-market equity program, incorporation by reference into Form F-10EF and Form S-8 registration statements, project finance updates, offtake documentation, and formal reporting status as a Form 40-F filer.
Standard Lithium Ltd. (SLI), through its Smackover Lithium partnership with Equinor, announced a binding take-or-pay offtake agreement for the South West Arkansas Project with LG Energy Solution. The SWA Project will supply 8,000 metric tonnes per year of battery-quality lithium carbonate to LG Energy Solution over a 10-year period following the start of commercial production. Pricing and other commercial terms are confidential but are described as supporting anticipated project financing.
The SWA Project targets customer offtake agreements covering roughly 80% of its initial 22,500 metric tonnes per year nameplate lithium carbonate capacity. Combining this agreement with the previously announced Trafigura offtake for 8,000 metric tonnes per year means about 90% of the targeted offtake volume is now committed. Smackover Lithium has received indications of interest for over $1 billion in project debt from three Export Credit Agencies, with due diligence underway. The partnership is targeting a Final Investment Decision this year, with construction planned to begin promptly afterward and first commercial production expected in 2029. Standard Lithium holds a 55% interest in the projects, with Equinor holding 45%.
Standard Lithium Ltd. reported a maiden NI 43‑101 Inferred Mineral Resource for the Franklin lithium‑brine project in east Texas, held via the Smackover Lithium joint venture with Equinor (55% Standard Lithium, 45% Equinor). The resource is hosted in the Upper and Middle Smackover Formation beneath a project area of 32,455 ha, with estimates based on 18,732 ha of gross leased brine mineral rights and extensive well, core, seismic, and brine sampling data.
The Inferred Resource totals 406,000 tonnes lithium (2,159,000 tonnes LCE), 2,638,000 tonnes bromide, and 8,070,000 tonnes potassium, contained in 0.61 km³ of brine, with average lithium concentrations around 668 mg/L. These resources are classified as Inferred and are explicitly stated not to have demonstrated economic viability or to constitute mineral reserves.
Independent Qualified Persons conclude that drilling, logging, coring, and analytical work support the Inferred classification and recommend further work to upgrade confidence and advance project definition. Suggested next steps include re‑entering 2023 wells for additional sampling and production testing, drilling two more exploration wells, updating geological and reservoir simulation models, and conducting targeted metallurgical test programs, with total recommended work of approximately US$19.5 million.

Sales may be made as at-the-market offerings on the TSX Venture Exchange and NYSE American under the company’s existing short form base shelf prospectus and Form F-10 shelf registering up to US$1,000,000,000 of securities.
The company already has a prior US$50,000,000 ATM program under which 8,978,213 shares have been sold for proceeds of US$36,012,156, leaving US$13,987,844 of capacity that will be used before issuing Placement Shares under the new agreement. Authorized capital includes an unlimited number of common shares, with 246,411,248 common shares outstanding as of the agreement date.
Standard Lithium Ltd. reported operational progress for the three and six-month periods ended June 30, 2026, focused on advancing the South West Arkansas (SWA) lithium project and its broader Smackover portfolio.
The U.S. Department of Energy completed its National Environmental Policy Act review of the SWA Project with a Finding of No Significant Impact, satisfying a key requirement linked to a previously awarded $225 million DOE grant. The company executed two major construction agreements: an EPCC contract with S&B Engineers and Constructors for the central processing facility and an EPCM contract with Wood Group USA for the upstream well field, both with Limited Notices to Proceed ahead of a potential Final Investment Decision (FID).
At its Arkansas demonstration plant, Standard Lithium achieved processing of 1 million barrels of brine, over 15,000 Direct Lithium Extraction cycles, and roughly 340,000 man hours with zero incidents. As of June 30, 2026, the company reported $137.3 million in cash, $137.1 million in working capital, and no term or revolving debt, while targeting FID later in 2026 and first commercial lithium carbonate production in 2029.
Standard Lithium Ltd. reported Q2 2026 results as an exploration and development-stage lithium brine company with projects in the Smackover Formation in Arkansas and East Texas. It remains pre-revenue.
Total assets were $397.3 million at June 30, 2026, including $137.3 million of cash and a $193.1 million equity-method investment in Smackover Lithium. Working capital was $137.1 million, and the company reported minimal long-term debt and lease liabilities.
The company recorded a Q2 2026 net loss of $3.1 million and a six‑month loss of $5.8 million, reflecting general and administrative spending, Demonstration Plant costs and its share of Smackover Lithium losses, partly offset by $2.3 million of interest income and a $4.9 million foreign exchange gain year to date.
Smackover Lithium advanced the South West Arkansas Project, securing a NEPA Finding of No Significant Impact, awarding key EPC/EPCM contracts, and maintaining a long-term offtake with Trafigura for 8,000 metric tons per year of battery-quality lithium carbonate over 10 years. Standard Lithium strengthened its balance sheet via its at-the-market equity program, issuing 5.4 million shares for gross proceeds of $22.1 million in the first half of 2026.

The company paid US$281,780 in commissions and fees to its agents under the program. Standard Lithium describes itself as a near-commercial lithium development company focused on high-grade lithium-brine projects in Arkansas and Texas, using a scalable direct lithium extraction and purification process.
Standard Lithium Ltd. filed a Form 6-K highlighting two related material changes for its South West Arkansas lithium project, held through the Smackover Lithium partnership with Equinor subsidiaries. Smackover Lithium has entered into an engineering, procurement, and construction management (EPCM) agreement with Wood Group USA for the upstream well field, and an engineering, procurement, construction, and commissioning (EPCC) agreement with S&B Engineers and Constructors for the Central Processing Facility (CPF).
The project is designed to produce 22,500 tonnes per annum of battery-quality lithium carbonate in its initial phase. The well field covers four pads with twelve supply and ten injection wells, associated pipelines, and gas gathering, accounting for less than one‑third of estimated capital expenditure, while the CPF represents approximately two‑thirds. Both agreements include Limited Notices to Proceed for detailed engineering, permitting and early procurement, with Full Notices to Proceed expected after a positive Final Investment Decision anticipated in 2026.
The company states that, together with the EPCM agreement for the wellfield and the EPCC agreement for the CPF, key construction vendor contracts needed before a Final Investment Decision are now complete, and Smackover Lithium is focusing on customer offtake arrangements and project financing.
