GNTXGentex Corporation
Is the business good?
The checks split: nothing decisive, though earnings fully cash-backed (1.4×).
Mixed fundamental signals. Nine pass/fail tests of year-over-year health from the filings.
Operating profit is fully backed by cash.
Positive operating leverage, operating profit is growing faster than sales, so margins widen as the business scales.
Margin-driven, fat margins on slower asset turns. ROE 16% = margin × turnover × leverage.
Unless marked, from derived.

Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.
