Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-02-14 to 2025-06-14. 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 2026-01-20)
Why this score: filed late on 2026-01-20
