The total for the nine months ended September 30, 2025 is negative due to the Company’s invoicing to General Atomics under the Cost Share Agreement during the nine-month period of certain prior period Demonstration Plant expenses. Formerly, these expenses were excluded from the Company’s billings under the Cost Share Agreement. The Company’s earlier decision to exclude these otherwise eligible costs from its billings to the Demonstration Plant project reflected the Company’s belief at the time that these costs would cause the original Cost Share Agreement award of $43,800 being exceeded, and therefore not recoverable. The subsequent increase in the Cost Share Agreement award to $53,600 led to the re-evaluation of this earlier decision and the decision to invoice the project for certain of these prior period expenses, which it did in the third quarter of 2025, and which resulted in the Company’s share of the Demonstration Plant project costs for the nine months ended September 30, 2025 being negative.
