Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-08-14 to 2025-12-12. 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.

Verified excerpt

"Based on our available cash resources and current operating plan, there is substantial doubt regarding our ability to continue as a going concern for a period of twelve months from the date the interim financial statements included in this Quarterly Report on Form 10-Q are issued."

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 2025-09-30)

Why this score: quarterly (unaudited) disclosure
