● ● ● Livent Livent Expansion Opportunities Brine-based Production Lithium Carbonate Livent has been extracting Lithium Brine at Salar del Hombre Muerto in Argentina for more than 25 years One of the lowest cost resources globally for Lithium Carbonate (current capacity -20,000 metric tons) and Lithium Chloride (~9,000 metric tons) (¹) Proprietary extraction process enables Livent to produce high quality, low impurity Lithium Carbonate Lithium Carbonate currently serves as the feedstock for Livent's downstream Lithium Hydroxide production Targeting total Carbonate capacity in Argentina of 100,000 metric tons by the end of 2030 Lithium Hydroxide Currently producing qualified battery- grade Lithium Hydroxide in both the U.S. and China (current capacity of -15,000 metric tons in each region) Livent's operational flexibility and proven capabilities are valued by global customers looking to localize battery material supply chains Modular expansion allows Livent to build new capacity quickly and efficiently in various locations Evaluating building a plant that would process recycled lithium material from batteries into Lithium Hydroxide Targeting total Hydroxide capacity of at least 55,000 metric tons by the end of 2025 (excluding Nemaska) Hard-Rock Production Nemaska Lithium: Fully Integrated Hydroxide Production Large and competitive spodumene resource in Québec, Canada, with strong sustainability profile Strategic and supportive location in Québec, Canada with ability to serve customers in North America and Europe Livent to contribute technical and commercial expertise to Nemaska Lithium in the development and future operation of the project Livent holds a 50% ownership interest in Nemaska Lithium (2) Potential for Livent to increase position in Nemaska over time Source: Company filings and materials. (1) Represents theoretical capacity for Lithium Carbonate and Lithium Chloride. Actual combined production of both products is lower and limited by the total capacity of lithium brine production. (2) Livent announced on May 2, 2022 an agreement to double its ownership interest to 50% in Nemaska Lithium. 6
