Return from the last close before the filing date to the first close on/after the window end. Pending windows have not fully elapsed. Past performance says nothing certain about the future.
90 days before the flag: no open-market insider sales or purchases reported.
30 days after: none reported.
Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-05-16 to 2025-09-13. 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.
The company told the SEC it could not file its quarterly report on time (Form NT 10-Q) and then missed the 5-day extension too. Repeated late filings are a stronger warning.
Status: filed late (report filed 2025-11-26)
Why this score: filed late on 2025-11-26; also within 90 days: Auditor change
