Going-concern doubt
— flagged Aug 11, 2026
Substantial doubt about the company's ability to continue as a going concern.
“The Company continues to incur losses from operations, negative cash flows from operations, as well as having a continued dependence on equity and debt financing. These conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date of these financial statements.”View the 10-Q filed Aug 11, 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.
