| Commitments and Contingencies | 10. Commitments and Contingencies The Company has been in settlement negotiations with a representative for six stockholder plaintiff firms alleging the Company violated Delaware law in its preliminary proxy statement that was disseminated to stockholders in November 2022 for the Company’s annual meeting held in December 2022. Based on these settlement negotiations to date, the Company estimates that it will settle for no more than an aggregate of $0.2 million and, therefore, has an accrual for the estimated liability of $0.2 million as of June 30, 2025 and December 31, 2024. This balance is included in accrued expenses on the unaudited Condensed Consolidated Balance Sheets. In May 2025, the Company entered into a purchase order with the U.S. Department of Energy (DOE) under which the Company will purchase thorium-228 from the DOE during 2025 and 2026. The purchase order includes a “take-or-pay” provision pursuant to which the Company is committed to purchasing approximately $8.4 million of thorium-228 during the term of the agreement. |
