SLI · Standard Lithium Ltd.

This 6-K filing discloses a material financing event: Standard Lithium executed an at-the-market (ATM) equity offering during the quarter ended March 31, 2026, raising US$11.0 million in gross proceeds through the issuance of 2.27 million common shares on the NYSE American at an average price of US$4.86. The transaction incurred US$0.3 million in commissions, consistent with typical underwriting fees for ATM programs. While not debt, this equity financing falls under Item 2.03 (Debt or Financial Obligation) per SEC guidance, as ATM programs are treated as financial arrangements involving ongoing securities sales obligations under a binding sales agreement. The ATM Program—launched August 8, 2025, with Canaccord Genuity and Evercore ISI as agents—retains US$38.97 million of unused capacity against its US$50.0 million ceiling, providing the Company continued flexibility to fund project development without committing to fixed-size offerings. Management’s stated use of proceeds is general corporate purposes, explicitly tied to advancing the SWA Project in southern Arkansas and the Franklin Project in East Texas—both central to the Company’s near-commercial strategy. Given the absence of earnings, acquisitions, executive changes, or regulatory triggers, and the moderate size relative to the Company’s overall capital needs, this represents a routine but operationally significant capital raise for a pre-revenue development-stage lithium company.
