Piotroski F-Score
4/9mixed

Altman Z″is a textbook bankruptcy-distress score from book values only (>2.6 safe · 1.1–2.6 grey · <1.1 distress). Accruals = (net income − operating cash flow) ÷ assets; persistently high accruals are an earnings-quality red flag. Beneish M-Scoreis an eight-ratio screen comparing this year with last (M > −1.78 = elevated manipulation-risk screen, not proof). Piotroski F-Scorecounts how many of nine fundamental-health checks pass (shown as passed / applicable; we use operating margin and total liabilities as documented proxies where the exact input isn't XBRL-tagged). Computed from SEC filings — descriptive factors, not advice or a forecast.

Our own multi-factor score from free SEC data — profitability, growth, financial strength, earnings quality, and event/ownership catalysts. No market price and no licensed model: each axis is the share of source-backed checks it passes. Descriptive factors, not advice or a forecast.

Risk flags

late SEC filings

A Form NT means the company notified the SEC it would file a periodic report late — often an accounting, audit or liquidity warning sign. Also search SEC enforcement actions for this company.

5%+ owners

SEC Schedule 13D / 13G · last 3 yrs

Holders who disclosed a 5%+ stake. 13D signals intent to influence or control; 13G is a passive holding. Latest filing per holder — open it for the exact stake.
