Gentex Corporation (GNTX): fair value, margin of safety and Wheel Score

Is GNTX undervalued?

At 21.11 (close of 16 Oct 2026), GNTX trades 41% below the GLS average fair value of 35.91. That average comes from 9 models run on the latest filings, and 7 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns Gentex Corporation the full Value points in the Wheel Score - and a closer look at what the market is pricing in.

There is a wide gap between DDM (7.06) and Payback Time (66.24). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.

The nightly engine files GNTX under Quality / Blue-Chip: a high moat score and a high health score together.

Nine valuation models for GNTX

Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

Quality and financial health

Gentex Corporation scores 8 of 9 on the Piotroski F-score, the nine yes/no tests of profitability, leverage and efficiency on the latest annual accounts - a strong reading that passes the Sunday Scan's "6 or more" rule with room to spare. A GLS Moat score of 7.9/10 puts GNTX among the more durable businesses we track: over ten years the metrics the score watches (revenue, EPS, book value, margins, cash flow, ROIC) have mostly moved the right way, year after year.

Returns on capital are high - ROIC 15.4%, ROE 15.5%, ROA 13.1% - with debt at 0.00 times equity and a free-cash-flow yield of 11.2%.

The dividend yield is 2.27% at a payout ratio of 26%; for a wheel trader holding assigned shares the dividend adds to the covered-call premium, and the ex-dividend date is worth knowing before a call is sold. Revenue comes mainly from Automotive Products 90%, Other Products 6%, Aftermarket Products 2% (quarter Q2 FY2026).

Institutional ownership scores 10/10, insider activity 2/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 93: Prime

With a Wheel Score of 93, Gentex Corporation sits in the Prime band - price, quality and premium all line up for the wheel strategy. The parts: Value 25/25, Health 18/20, Moat 12/15, Premium 20/20, Stability 19/20. A high score is a ranking, not a signal: it says nothing about timing, the earnings date or your position size.

Implied volatility is 36% on the near-the-money contracts 20-60 days out - inside the 35-60% range the Wheel Score pays full marks for: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is 2,319 contracts across all expiries - enough for the wheel at normal size.

Volume runs at 4.3M shares a day on a market cap of $4.4B, with a beta of 0.85; the Stability part of the Wheel Score gives that 19 of 20.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls; it is updated nightly and is not a recommendation. The walkthrough lesson shows how the score fits into a trade, start to finish.

Upcoming events

Gentex Corporation reports earnings on 23 Oct 2026 (before the open) - inside the 14-day window the Sunday Scan avoids, because a put sold now would carry the report's gap risk.
