Note 2 – Concentrations of credit risk

 

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We maintain our cash and cash equivalents with high-credit quality financial institutions. At April 30, 2025, we had cash and cash equivalent balances in excess of federally insured limits in the amount of approximately $3.3 million.

For the three months ended April 30, 2025, one wireless provider accounted for 11% of net sales and 16% of total net accounts receivable balance. One distributor with less than 10% of total net sales, accounted for 10% of total net accounts receivable balance. For the six months ended April 30, 2025, a different wireless provider accounted for 11% of net sales and less than 10% of total net accounts receivable balance, and a wireless provider and the same distributor, whose sales were both less than 10% of total net sales, accounted for 16% and 10% of total net accounts receivable balance, respectively. For the three months ended April 30, 2024, no customers accounted for 10% or more of net sales, and one wireless provider and one distributor, whose sales were both less than 10% of total net sales, accounted for 15% and 10% of total net accounts receivable balance, respectively. For the six months ended April 30, 2024, no customers accounted for 10% or more of net sales, and two distributor customers, whose sales were both less than 10% of total net sales, accounted for 15% and 10% of total net accounts receivable balance, respectively. Although these customers have been significant customers of the Company, the written agreements with these customers do not have any minimum purchase obligations and these customers could stop buying our products at any time and for any reason. A reduction, delay or cancellation of orders from these customers or the loss of these customers could significantly reduce our future revenues and profits.
