We maintain our cash and cash equivalents with high-credit quality financial institutions. At  July 31, 2026, we had cash and cash equivalent balances in excess of federally insured limits in the amount of approximately $3.7 million.

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.
