Going-concern doubt
— flagged Apr 30, 2026
Substantial doubt about the company's ability to continue as a going concern.

While management has implemented plans to obtain additional funding, these plans are not sufficient to alleviate the substantial doubt about the Company's ability to continue as a going concern.”View the 10-Q filed Apr 30, 2026
