— flagged Jul 31, 2026
Substantial doubt about the company's ability to continue as a going concern.
“These factors raise substantial doubt about the Company's ability to continue as a going concern within one year after the date these financial statements are issued. Although management has implemented the plans described above, it cannot conclude that such plans are probable of effectively mitigating the conditions and events that raise substantial doubt. Accordingly, substantial doubt exists about the Company's ability to continue as a going concern for the one-year period following the issuance of these financial statements.”View the 10-Q filed Jul 31, 2026
