INVENTORY | ​ 4. INVENTORY ​ Inventory consisted of raw material of natural flake graphite concentrate provided by a third-party vendor totaling $0.2 million and $0.5 million as of June 30, 2025, and December 31, 2024, respectively. For both periods, the raw material inventory balance is either under contract to be sold or will be used to produce samples within the next twelve months. The full balance of inventory as of June 30, 2025, and December 31, 2024, is included in the “Prepaid and other current assets” line item on the Condensed Consolidated Balance Sheets. ​ The Company values the natural flake graphite concentrate at the lower of cost or net realizable value. Net realizable value represents the estimated future sales price of the product based on current and long-term graphite prices, less the estimated costs to complete production and bring the product to sale. For sales of raw material inventory that will not be processed, the net realizable value is the contracted sales price. Write-downs of the natural flake graphite concentrate to net realizable value are reported as a component of costs applicable to sales or as a component of “other expense, net” if related to the sale of raw material inventory. The Company reviews and evaluates the net realizable value and obsolescence on an annual basis or more frequently when events or changes in circumstances indicate that the related net realizable amounts may be lower than cost. For the three and six months ended June 30, 2025, there were no write-downs of the Company’s inventory. For the three and six months ended June 30, 2024, the Company recognized a $0.7 million write-down of inventory based on the net realizable value of future committed sales of raw material inventory. ​ ​ ​ ​
