**Standard Lithium Announces New VP Appointments to Expand and Strengthen Senior Management**

VANCOUVER, British Columbia, June 23, 2025 (GLOBE NEWSWIRE) -- **Standard Lithium Ltd.** ("Standard Lithium" or the "Company") (TSXV:SLI) (NYSE American:SLI), a leading near-commercial lithium company, is pleased to announce the appointment of Daniel Rosen as Vice President of Strategy and Investor Relations, as well as Tim Sobel as Vice President of Health, Safety, Social and Environment ("HSSE").

"We are thrilled to welcome the additions of Daniel and Tim to our leadership team," said David Park, Chief Executive Officer and Director of Standard Lithium. "Dan's strategic insight and deep experience in investor relations and capital markets, as well as Tim's extensive history in ensuring that HSSE standards are not only met, but exceeded and built-in to organizational culture, will be invaluable as we continue to execute our growth strategy on a path towards first production."

"Bringing on Daniel and Tim is the next step in our process of continuing to evolve and strengthen our capabilities," said Salah Gamoudi, Chief Financial Officer of Standard Lithium. "We'd also like to thank Chris Lang for helping to support our investor relations function this past year. With Daniel coming onboard, this will allow Chris to prioritize and focus more on the financial planning and treasury aspects of his role."

Mr. Rosen brings more than 13 years of experience in corporate strategy, finance, and capital markets. Most recently, Mr. Rosen played a key role in the post-acquisition integration of Arcadium Lithium into Rio Tinto, where he led cross-functional initiatives to align strategic priorities, operational capabilities, and investor messaging. Prior to his role as Director of Integration for Rio Tinto, Mr. Rosen held roles in Corporate Strategy, M&A and Investor Relations for Arcadium Lithium and Livent and spent over six years with Barclays in its Investment Banking division. He has a proven track record of aligning corporate vision with market opportunities and building trusted relationships across the investment community.

Mr. Sobel is a seasoned HSSE executive with over three decades of distinguished leadership in health, safety, security, environmental, quality, sustainability, and risk management across global industrial and logistics sectors. He most previously served as Vice President of HSSE for the Americas at DP World, where he oversaw HSSE strategy and execution across more than 40 logistics, port, and terminal operations in North and South America. Prior to DP World, he held senior leadership roles at Air Liquide, New Fortress Energy, Wilhelmsen Ship Management, and Sunoco Logistics, where he led multi-site operational risk, compliance, and crisis management programs. His earlier service in the U.S. Coast Guard laid the foundation for his deep regulatory expertise and command-level emergency response capabilities. Mr. Sobel is recognized for developing and embedding world-class safety cultures, behavioral safety programs, and regulatory-compliant management systems.
