Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-06-13 to 2025-10-11. 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.

Verified excerpt

"However, substantial doubt about the Company's ability to continue as a going concern exists."

Quoted from the filing. Source

What this means

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.

Source: management disclosure in Form 10-Q (period 2025-06-30)

Why this score: quarterly (unaudited) disclosure; also within 90 days: Auditor change, Late annual report (NT 10-K), Late quarterly report (NT 10-Q), Non-reliance / restatement
