2026-08-12: red flag filed

Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2026-05-14 to 2026-09-11. 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.

What this means

The company filed Form NT 10-Q, telling the SEC it could not file its quarterly report on time, and then filed the report within the 5-day extension. The SEC treats a report filed within the extension as timely, so this is the mildest kind of flag, but the notice itself is a warning sign that investors often react to: something, often the audit or the accounting, took longer than planned.

Status: filed within extension (report filed 2026-08-17) · the SEC treats a report filed within the extension as timely

Why this score: report filed within the extension on 2026-08-17
