Unbilled receivables as of July 31, 2025 relate to contracts-in-progress for which revenue has been recognized, but for which we have not yet earned the right to bill the customer for work performed to-date. Under ASC 606, unbilled receivables constitute contract assets.

During the fiscal year ended July 31, 2025, we reversed cumulative revenues and associated contract receivables due to changes in estimates of revenue and costs for certain contracts. With respect to such changes in estimates, we:

•determined that an unbilled receivable contract asset in the amount of $17,685,000, related to an international customer and reseller of our troposcatter technologies, was at risk of not being invoiced or collected, principally due to a change in our customer's near-term ability to secure certain opportunities in its pipeline. As a result, and considering that we offered a price concession (i.e., variable consideration) to our customer in the first quarter of fiscal 2025, we reversed $1,551,000 of cumulative revenue and associated unbilled receivable contract assets related to this transaction, and recorded a non-cash charge to fully reserve for the remaining $16,134,000 unbilled receivable contract asset within our allowance for doubtful accounts;

•reversed $4,157,000 of cumulative revenue and $3,003,000 of associated unbilled receivable contract assets as a result of terminating certain customer contracts during the first quarter of fiscal 2025 in connection with the CGC Divestiture;

•reversed $3,030,000 of cumulative revenue and $2,324,000 of associated unbilled receivable contract assets due to an increase in our estimates of engineering activities, budgeted time and related costs to complete a development project that commenced in fiscal 2023 in our Satellite and Space Communications segment and with an international customer; and

•reversed $2,286,000 of cumulative revenue and $2,234,000 of associated unbilled receivable contract assets due to higher expected costs at completion identified during fiscal 2025, as we advanced certain nonrecurring engineering related projects in our satellite ground infrastructure product line through development and toward production.

After adjusting for those amounts identified above, and excluding unbilled receivables related to the U.S. Marine Corps contract discussed below, management estimates that a substantial portion of the remaining contract assets not yet billed at July 31, 2025 will be billed and collected within one year. Accounts receivable in the table above excludes $824,000 of long-term unbilled receivables presented within "Other assets, net" in the Consolidated Balance Sheets as of July 31, 2024.

As of July 31, 2025, the U.S. government (and its agencies) and two domestic top tier mobile network operators represented 25.1%, 14.5% and 10.5% of net accounts receivable, respectively. There were no other customers which accounted for greater than 10.0% of net accounts receivable.

As of July 31, 2024, the U.S. government (and its agencies), an international customer and reseller of our troposcatter related technologies and a domestic top tier mobile network operator represented 36.7%, 11.4%, and 11.0% of net accounts receivable, respectively. There were no other customers which accounted for greater than 10.0% of net accounts receivable.

In our troposcatter product line, throughout most of fiscal 2024, we experienced elevated levels of receivables due to the timing of our performance on and billings and collections related to certain large U.S. government and international customer contracts. During principally the first half of fiscal 2025, we maintained deliveries of next-generation troposcatter terminals related to our U.S. Marine Corps and Army end user contracts, contributing to a 26% year-over-year reduction in our consolidated receivables as of July 31, 2025. In December 2024, however, we received a notice from our prime contractor to stop work associated with the U.S. Marine Corps contract. Such contract was subsequently terminated. We have initiated litigation against the prime contractor in order to enforce our rights and recover $15,701,000 of total receivables related to this contract as of July 31, 2025. While we believe that we have meritorious claims, some or all of such receivables could be at risk of not being collected. Future results of operations related to our troposcatter solutions product line depend, in part, on the nature, timing and amount associated with resolving this matter.
