MATERIAL CHANGE REPORT

Standard Lithium Ltd. (the “Company”)

Suite 1625 – 1075 West Georgia Street
Vancouver, BC V6E 3C9

August 27, 2026

The news release was disseminated by Globe Newswire on August 31, 2026, and was subsequently filed on SEDAR+.

Smackover Lithium, a partnership between the Company, through its subsidiaries, and Equinor, through subsidiaries of Equinor ASA, announced the signing of its second commercial offtake agreement for the South West Arkansas Project (the “Project”) with LG Energy Solution, Ltd.

Smackover Lithium announced the signing of its second commercial offtake agreement for 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 “Agreement”), the 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.

The 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 Project financing process and is critical to supporting the contemplated debt size, duration and structure. Smackover Lithium provided a financing update on December 9^th, 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 (“FID”). Construction is planned to begin promptly following FID, enabling first commercial production of battery-quality lithium carbonate in 2029.
