Red Flags & Health Score

One glance: a health score and every red flag we can read from a company’s SEC filings — going-concern, bankruptcy risk, earnings-manipulation, dilution, restatements — plus the part others miss: who’s actually buying (insiders, Congress, funds).

promotion structurefilings to 2026-11-03

Six filed conditions that make a stock easier to promote, and so the ones a promoter selects for. Each one also has ordinary reasons. This is structure read from SONO’s filings, not a finding that anyone is promoting the stock.

1 of the 6 conditions present, from 6 read.

Small floatNot found
118.3 million shares outstanding as of 2026-07-20 (10-Q), at or above 30.0 million. The float could still be small if insiders hold much of it; this count cannot show that. The filing ↗
Effective shelf (S-3) or S-1 registrationNot found
In the filing record: no effective S-3 shelf and no S-1 in the window.
Recent financing in an 8-KNot found
No 8-K under Item 3.02, and no agreement 8-K beside a prospectus, since 2026-05-07.
Insider or affiliate sellingPresentFiling evidence
3 open-market sales on Form 4 since 2026-05-07, 3 of them filed with the Rule 10b5-1 box checked; the newest by Boone Karen (Director) on 2026-09-25. Also 4 Form 144 notices. The filing ↗
Reverse splitNot found
No 8-K under Item 5.03 naming a reverse stock split since 2025-11-03.
Exchange listing noticeNot found
No 8-K under Item 3.01 since 2025-11-03.

Filing evidence: the filing itself states the condition. Inference: we conclude it from timing or from our stored prices, and say from what. Shelf, reverse split and listing notice are read over 365 days; financing and insider selling over 180. A condition we could not read is never counted as absent.
