Going-concern doubt
— flagged Aug 18, 2026
Substantial doubt about the company's ability to continue as a going concern.
“Because our cash and cash equivalents, together with $51.1 million of net proceeds from our August 2026 Offering, will not be adequate to fund our currently planned operations through at least the 12 months from the date of this Quarterly Report, there is substantial doubt about our ability to continue as a going concern.”View the 10-Q filed Aug 18, 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.
