Prepaid Project Costs and Other Longterm Assets |
Prepaid Project Costs and Other Long-term Assets | Note 3. Prepaid Project Costs and Other Long-term Assets In 2022, the Company entered into two agreements with Idaho National Laboratory (INL), in collaboration with the Department of Energy (DOE), to support the development of Lightbridge Fuel™. At the time of signing, the Company made advance payments for future project work totaling $0.4 million to Battelle Energy Alliance, LLC (BEA), the DOE’s operating contractor for INL. In May 2023, the Company and INL modified the agreements to extend the contract term to May 2029, aligning it with the duration of the irradiation testing, and increasing the advance payments by $0.1 million to $0.5 million. During the quarter ended March 31, 2025, the Company made additional advance payments of $0.6 million which subsequently offset $0.4 million in project costs. As of March 31, 2025, and December 31, 2024, the Company’s prepaid project costs were $0.7 million and $0.5 million, respectively.
