Why it matters

  1. What Gentex does

    Gentex designs and manufactures digital vision, auto-dimming rearview mirrors, and electronic features for global automakers who pay per vehicle built. The business is pushing deeper into camera-based driver assistance systems and full display mirrors to secure future vehicle design wins.

  2. What it does best

    Gentex dominates the global market for auto-dimming mirrors with a gross margin of 35%, vastly outperforming peers like BWA at 20.1% and LEA at 7.7%. This edge stems from decades of specialized optical patents and high-volume manufacturing that rivals cannot easily replicate.

  3. The main risk

    With nearly all revenue tied to global vehicle production, broader automotive output slumps directly compress volume and factory efficiency. If carmakers cut build schedules, Gentex absorbs the volume drop immediately.

Quality, check by check

Scored against its own industry, from company filings.

ProfitabilityFair

Gross margin stands at 35% with an operating margin of 19.6%, ranking in the top quartile of its sector. High FCF margin of 86th percentile shows strong cash conversion as scale increases.

MoatFair

Automaker integration creates a sticky design-win moat, backed by an operating margin sitting in the 78th sector percentile. Rivals face steep engineering hurdles to displace embedded mirror electronics.

GrowthSteady

Revenue grew 9.6% to $2.6B, accelerating past its historical multi-year expansion rate as new electronic mirror adoption gains traction across global auto fleets.

Financial healthStrong

Net cash sits at $147 million against total debt of just $4 million, leaving the balance sheet virtually debt-free. Free cash flow reached $495 million, getting stronger as cash generation scales.

Insiders

Executives and directors, from SEC Form 4 filings we read ourselves. Open market trades only; grants, option exercises and pre-planned sales left out.

No open market buys or unplanned sales by executives or directors.
