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 2026-03-23) · the SEC treats a report filed within the extension as timely

Why this score: report filed within the extension on 2026-03-23
