Is it safe?

Watch

Solid, nothing alarming: clean books, but heavy debt (BB) and big price swings.

1 good, 2 to watch, 3 neutral
SurvivalGrey zone

Mixed, watch the balance sheet 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).

Quality5 / 9

Mixed fundamental signals 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-$207K

Insiders were net sellers (-$207K, 90 days to Oct 22, 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.
