Insider trading around this filing

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 2025-12-02 to 2026-04-01. 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-K, telling the SEC it could not file its annual report on time, and then filed the report within the 15-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 2026-03-06) · the SEC treats a report filed within the extension as timely

Why this score: report filed within the extension on 2026-03-06
