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 January 31, 2025, we had cash and cash equivalent balances in excess of federally insured limits in the amount of approximately $1.3 million.

 

Sales from each customer that were 10% or greater of net sales were as follows:

     21 %     -  

 

For the three months ended January 31, 2025, one wireless carrier accounted for 21% of net sales and 21% of net accounts receivable. For the three months ended January 31, 2024, no customers accounted for 10% or more of net sales, and two distributor customers accounted for 10% each of total net accounts receivable. 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.
