Standard Lithium Advances Arkansas and Texas Projects with $130 Million Financing and Key Milestones

Standard Lithium Ltd. (NYSE American: SLI) reported substantial progress across its lithium development portfolio for the third quarter of 2025, highlighted by the completion of a Definitive Feasibility Study for its South West Arkansas Project and a Maiden Inferred Resource for the Franklin Project in East Texas. CEO David Park emphasized that these results demonstrate the attractiveness and cost-competitiveness of the SWA Project while establishing a strong foundation for scalable production within the Smackover formation. The company's strategic advancements position it to reach final investment decision on the SWA Project and commence construction activities in 2026.

Following the quarter's end, Standard Lithium successfully closed an upsized $130 million underwritten public offering, providing substantial capital to advance both the SWA and Franklin projects simultaneously. This significant financing achievement, detailed in the company's official release available at https://ibn.fm/NPL11, represents a major milestone in securing the necessary funding for project development and construction phases. The capital infusion comes at a critical juncture as the company moves toward commercialization of its lithium brine assets.

The company also received final integration approval from the Arkansas Oil and Gas Commission, a crucial regulatory milestone that clears the path for project development in the region. This approval, combined with the reported highest lithium-in-brine grade to date from the SWA area at 616 mg/L, reinforces the project's technical and economic viability. The high-grade brine results underscore the quality of the resource and support the company's position in the competitive lithium market.

Standard Lithium's focus on sustainable development of large, high-grade lithium-brine properties in the United States aligns with growing demand for domestic lithium production. The company's partnership with global energy leader Equinor provides additional validation and support for the SWA Project's development. The combination of robust infrastructure, skilled labor availability, and streamlined permitting processes in the Smackover Formation region contributes to the projects' strategic advantages.

The company's application of scalable and fully integrated direct lithium extraction and purification processes represents a modern approach to lithium production. This technological approach, combined with the high-grade resources identified in both Arkansas and Texas locations, positions Standard Lithium to contribute meaningfully to the North American lithium supply chain.
