Note 10.  Fair Value of Financial Instruments​

​

The carrying value amounts of cash and cash equivalents, restricted cash, accounts receivable, prepaid expenses, notes receivable and other current assets, accounts payable, accrued expenses, bank acceptance payable and other current liabilities approximate fair value because of the short-term maturity of these instruments. The Company believes that the interest rates in effect at each period end represent the current market rates for similar borrowings. 

 

The Company's accounts receivable was $171.1 million as of March 31, 2025. Of this amount, $136.2 million was due from DigiComm International Inc. For the three months ended March 31, 2025 and 2024, our top ten customers represented 97% and 92% of our revenue, respectively.

 

The fair value of convertible senior notes is measured for disclosure purposes only. The fair value and carrying amount of our convertible senior notes as of  March 31, 2025 was $102.9 million and $134.2 million, respectively. As of December 31, 2024, the fair value and carrying amount of our convertible senior notes were $148.6 million and $134.5 million, respectively. The fair value is based on observable market prices for this debt, which is traded in less active markets and are therefore classified as a Level 2 fair value measurement.
