(a)Includes $306.1 million and $290.6 million at March 31, 2025 and December 31, 2024, respectively, of work in process in our Energy Storage segment. (b)As a result of the decline in lithium market pricing, the Company recorded charges in Cost of goods sold to reduce the value of certain finished goods and spodumene to their net realizable value. The balance of these inventory valuation adjustments totaled $6.6 million and $104.0 million at March 31, 2025 and December 31, 2024, respectively. During the three-month periods ended March 31, 2025 and 2024, the Company utilized $97.3 million and $194.2 million, respectively, of the inventory valuation adjustments as the inventory was sold, which are included within Working capital changes on the condensed consolidated statement of cash flows. The Company purchases certain of its inventory from its equity method investments (primarily the Windfield Holdings Pty. Ltd. (“Windfield”) joint venture) and eliminates the balance of intra-entity profits on purchases of such inventory that remains unsold at the balance sheet date in Inventories, specifically finished goods and equally reduces Equity in net income of unconsolidated investments (net of tax) on the consolidated statements of income. The balance of intra-entity profits on inventory purchased from equity method investments in Inventories totaled $68.1 million and $66.8 million at March 31, 2025 and December 31, 2024, respectively. The intra-entity profit is recognized in Equity in net income of unconsolidated investments (net of tax) in the period that converted inventory is sold to a third-party customer. In the same period, the intra-entity profit is also recognized as higher Cost of goods sold on the consolidated statements of income.
