Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2026-05-15 to 2026-09-12. Excludes option exercises, grants, gifts and tax withholding. Amended filings replace the originals; joint filings count once. Foreign private issuers do not file Form 4. Many insider sales are pre-scheduled (10b5-1 plans) and are not by themselves a sign of wrongdoing.
"These factors raise substantial doubt about the Company's ability to continue as a going concern."
Quoted from the filing. Source
The filing states that substantial doubt exists about the company's ability to continue as a going concern: it may not have enough cash to last the next 12 months. Expect dilution, debt deals or worse. An auditor's going-concern paragraph is the strongest form of this warning.

Why this score: quarterly (unaudited) disclosure
