⁽¹⁾ As of December 31, 2025, the Company has a receivable from General Atomics due to the Company invoicing amounts during the third quarter of 2025 for certain Demonstration Plant expenses incurred in prior periods under the Cost Share Agreement. These expenses were initially excluded from the Company’s billings under the Cost Share Agreement because the Company believed at the time that including them would cause the original $43,800 award to be exceeded and therefore not recoverable. The subsequent increase in the Cost Share Agreement award to $53,600 prompted the Company to re-evaluate its prior position and invoice the project for certain of these previously excluded expenses. As a result, the Company’s share of Demonstration Plant project costs for the year ended December 31, 2025 was negative.
