Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2026-02-06 to 2026-06-06. 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.
"Despite the cost reductions and cash conservation measures, we will need additional debt or equity financing in order to meet our near-term operating cash flow requirements, and accordingly substantial doubt exists as to our ability to continue as a going concern for 12 months from the issuance of the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q. We have based our near-term operating cash flow requirements on certain assumptions, including that cash"
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
