Is it safe?

Good

Strong, no red flags: a safe balance sheet, clean books, and quality strong.

4 good, 2 neutral
SurvivalSafe zone

Financially healthy, low distress risk Altman Z-score, a bankruptcy-risk model from five balance-sheet ratios.

Honest booksLow risk

Reported earnings show no manipulation flags Beneish M-score, a forensic model that detects earnings-manipulation patterns (receivables outrunning sales, margins slipping, accrual-heavy profit).

Quality7 / 9

High fundamental quality Piotroski F-score, nine pass/fail tests of year-over-year financial health across profitability, balance sheet and efficiency. 7 to 9 is strong, 0 to 3 weak.

Insider conviction-$2.5M

Insiders were net sellers (-$2.5M, 90 days to Oct 8, 2026), selling is often routine.

Where this answer is blind. Altman sits structurally low for utilities and pipelines; Beneish runs high for fast growers, since sales growth alone lifts it; banks and REITs are excluded.
