Substantial doubt about the company's ability to continue as a going concern.
“The Company has not developed a commercially viable product, has not generated any significant revenue to date, and has incurred losses since inception, resulting in a net accumulated deficit of $48,621,796 and a working capital deficiency of $183,266 at December 31, 2025. These factors raise substantial doubt about the Company's ability to continue as a going concern.”View the 10-K filed Sep 3, 2026
Trades by corporate insiders — officers, directors and holders of more than 10% of the shares — disclosed to the SEC on Forms 4 and 5. Form 3 supplies initial ownership rather than a trade; Form 4 must be filed within two business days of the trade.
