The latest filing states the doubt was alleviated.
“The Company has limited cash resources, has incurred recurring operating losses and negative cash flows from its operations since its inception and has not yet recognized any product revenues. These factors have previously raised doubt about the Company's ability to continue as a going concern.”View the 10-Q filed Aug 6, 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.
