Smackover Lithium Signs Binding Customer Offtake with LG Energy Solution for the South West Arkansas Project
All figures are in US dollars unless otherwise stated.
LEWISVILLE, Ark., Aug. 31, 2026 (GLOBE NEWSWIRE) -- Smackover Lithium, a partnership between Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (NYSE.A: SLI) (TSXV: SLI), through its subsidiaries, and Equinor, through subsidiaries of Equinor ASA, announced the signing of its second commercial offtake agreement (the “Agreement”) for the South West Arkansas Project (“SWA Project” or the “Project”) with LG Energy Solution. LG Energy Solution is a leading global manufacturer of lithium-ion batteries for diverse applications including energy storage systems and electric vehicles.
Under the terms of this binding take-or-pay offtake Agreement, the SWA Project will supply LG Energy Solution with 8,000 metric tonnes per year of battery-quality lithium carbonate over a 10-year period following the start of commercial production. Pricing and other key commercial terms are subject to confidentiality but are structured to support anticipated financing for the Project.
David Park, Chief Executive Officer of Standard Lithium stated, “We are excited to be entering into this Agreement with LG Energy Solution, one of the world’s leading battery producers with a diverse and global customer base and a presence in many dynamic and growing industry segments. The Agreement further anchors our customer offtake portfolio, complementing the contract with Trafigura we announced in March of this year, and is another major milestone in the development of the SWA Project. We have now secured a vast majority of the offtake agreements needed to move forward with our Project financing plans and a Final Investment Decision. We expect this to be the beginning of a long and mutually beneficial partnership whereby we will provide LG Energy Solution with a long-term supply of U.S.-based and sustainably produced battery-quality lithium carbonate.”
“We are pleased to begin this partnership with Smackover Lithium and the Agreement marks another step toward establishing a solid and resilient supply chain that keeps our products competitive in key strategic markets,” said Kang Yeol Lee, Procurement Center Leader of LG Energy Solution. “By bringing both battery production and sourcing to the U.S., we will deliver competitive and sustainable products to our customers driving the global energy storage and EV markets.”
The SWA Project is seeking customer offtake agreements totalling roughly 80% of the 22,500 metric tonnes of annual nameplate lithium carbonate capacity for its initial phase. Combining this Agreement with the previously announced Trafigura offtake agreement for 8,000 metric tonnes per year over 10 years means that roughly 90% of the total targeted offtake volume has now been committed. The partnership remains in advanced discussions with several prospective customers and aims to conclude the offtake process shortly with the expectation of signing one additional smaller agreement.
The customer offtake process is being run in conjunction with the SWA Project financing process and is critical to supporting the contemplated debt size, duration and structure. Smackover Lithium provided a financing update on December 9th, 2025 highlighting indications of interest for over $1 billion in Project debt from three major Export Credit Agencies (“ECAs”). The due diligence and other customary processes by those ECAs in furtherance of the Project financing are well underway. The partnership is targeting a Final Investment Decision this year. Construction is planned to begin promptly following FID, enabling first commercial production of battery-quality lithium carbonate in 2029.
