Standard Lithium Advances Texas and Arkansas Projects with $130 Million Funding and Technical Milestones

Standard Lithium Ltd. reported substantial advancements across its lithium development portfolio during the third quarter of 2025, with key milestones achieved at both its South West Arkansas Project and the Franklin Project in East Texas. The company completed a Definitive Feasibility Study for the South West Arkansas Project while establishing a Maiden Inferred Resource for the Franklin Project, demonstrating the economic viability and scalability of lithium production in the Smackover formation.

Following the quarter's conclusion, Standard Lithium successfully closed an upsized $130 million underwritten public offering, providing critical capital to advance both projects toward development. This substantial financing positions the company to reach Final Investment Decision on the South West Arkansas Project, with construction potentially commencing in 2026. The company also secured final integration approval from the Arkansas Oil and Gas Commission, representing a crucial regulatory milestone for project advancement.

Technical achievements during the period included reporting the highest lithium-in-brine grade to date from the South West Arkansas area at 616 mg/L, indicating exceptional resource quality. The company's focus on sustainable lithium production through direct lithium extraction technology represents a significant advancement in domestic lithium supply chain development.

Standard Lithium's partnership with global energy leader Equinor further strengthens the company's position in advancing both the South West Arkansas Project and the Franklin Project in East Texas. The Smackover Formation, where both projects are located, represents a world-class lithium brine asset that could substantially contribute to North American lithium production capacity. The combination of high-grade resources, robust infrastructure, and streamlined permitting positions these projects as potentially significant contributors to meeting growing demand for lithium in electric vehicle batteries and energy storage applications.

The developments have significant implications for Texas and the broader energy sector, as domestic lithium production becomes increasingly critical for electric vehicle manufacturing and renewable energy storage. The East Texas Franklin Project's advancement represents a strategic expansion of lithium development in the state, potentially creating new economic opportunities while supporting the transition to cleaner energy technologies. The successful financing and technical progress demonstrate the commercial viability of lithium extraction in the region, which could establish Texas as a key player in the North American lithium supply chain.
