Going-concern doubt
— cleared Aug 6, 2026
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

Shares are restated onto today's split basis. Change compares each row with the same holder's previous filing in the same source; a dash means there is none to compare. Nested 13D/G, insider and fund rows are not summed, since a 13F report already holds them.
