Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2026-02-10 to 2026-06-10. 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.
"As disclosed in the Company's audited consolidated financial statements as of and for the year ended December 31, 2025, events and conditions existed which raised substantial doubt about the Company's ability to continue as a going concern, primarily due to recurring operating losses, negative cash flows from operations and liquidity constraints."
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
