| Financial Instruments with Concentrations of Credit Risk | FINANCIAL INSTRUMENTS WITH CONCENTRATIONS OF CREDIT RISK The primary customer of our Government Operations segment is the U.S. Government, including some of its contractors. Our Commercial Operations segment's major customers are large utilities. These concentrations of customers may impact our overall exposure to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic or other conditions. In the years ended December 31, 2025, 2024 and 2023, U.S. Government contracts accounted for approximately 68%, 76% and 75% of our total consolidated revenues, respectively. Accounts receivable due directly or indirectly from the U.S. Government represented 28% and 40% of net receivables at December 31, 2025 and 2024, respectively. In the years ended December 31, 2025, 2024 and 2023, revenues from four large utility customers accounted for approximately 17%, 14% and 14% of our total consolidated revenues, respectively. Accounts receivable due directly from four large utility customers represented 50% and 19% of net receivables at December 31, 2025 and 2024, respectively. See Note 15 for additional information about our major customers. We believe that our provision for possible losses on uncollectable accounts receivable is adequate for our credit loss exposure. At December 31, 2025 and 2024, the allowances for possible losses that we deducted from Accounts receivable – trade, net on our consolidated balance sheets were $0.6 million and $0.3 million, respectively.
