STANDARD LITHIUM RETAINS BNP PARIBAS TO LEAD DEBT ADVISORY SERVICES FOR FIRST COMMERCIAL PROJECT

Standard Lithium Ltd. has signed a mandate with BNP Paribas to act as exclusive financial adviser to the company in connection with limited recourse debt financing. The debt financing will be used to finance the majority of the company's proposed first commercial project, the Lanxess 1A project, located near El Dorado in southern Arkansas. BNP Paribas is a global leader in the financial advisory and project financing role for battery and critical mineral projects.

Dr. Andy Robinson, president of the company, commented: "We are delighted to start this engagement with BNP Paribas. Standard Lithium is in the closing stages of the definitive feasibility study (DFS) for our first commercial project, the Lanxess 1A project. As we move towards commercialization, we have kicked off the necessary financial processes to ensure the most capital efficient way to fund our first full-scale project. BNP brings an excellent track record of advising and securing debt financing for similar sustainable, battery and critical mineral projects, and we look forward to working closely with them as we endeavour to secure project financing for construction anticipated to begin next year."

Antonio Pichardo, director at BNP Paribas, said: "We are pleased to partner with Standard Lithium for this landmark debt financing. This new project is a testament to their commitment to environmental protection and demonstrates that we can meet the growing demand for lithium. BNP Paribas is determined to strengthen our climate action, in order to help our clients and our world to face the challenges of the future. We are looking forward to helping establish Standard Lithium as a leading producer of responsible lithium for the rapidly growing electric vehicle market."

About Standard Lithium Ltd.

Standard Lithium is a leading near-commercial lithium development company with a portfolio of projects in progress. The company's flagship projects, the Lanxess property project and the South West Arkansas project, are located in southern Arkansas near the Louisiana state line. The company is focused on the evaluation and testing of commercial lithium extraction and purification from brine sourced from approximately 180,000 acres of leases across these two projects. The company operates a first-of-a-kind industrial-scale DLE (direct lithium extraction) demonstration plant at the Lanxess property project. The scalable, environmentally friendly process eliminates the use of evaporation ponds, reduces processing time from months to hours and greatly increases the effective recovery of lithium. A definitive feasibility study (DFS) and front-end engineering study (FEED) for phase 1A of the Lanxess property project commenced in September, 2022. A preliminary feasibility study (PFS) of the South West Arkansas project commenced in May, 2022. The company is also pursuing the resource development of other projects in the Smackover formation in east Texas, as well as approximately 45,000 acres of mineral leases located in the Mojave Desert in San Bernardino county, California.
