Gentex

What Gentex does

Gentex Corporation is a Zeeland, Michigan-based technology company that develops electrochromic and digital vision systems, generating $2.53 billion in FY2025 net sales across automotive, aerospace, fire protection, and smart home markets. Its core product is the automatic-dimming rearview mirror, where the company holds 90% OEM penetration and ships nearly 50 million units annually into vehicles built by major global manufacturers. The technology stack extends from proprietary electrochromic chemistry through glass processing, vision systems, software, and vertically integrated manufacturing, enabling adjacent products including the Full Display Mirror (3.19 million units shipped in 2025, +7% YoY), Integrated Toll Modules, dimmable sun visors targeting the 2027 model year, and electronic dimmable windows for Boeing's 777X aircraft.

Revenue mechanics are dominated by tier-1 automotive OEM supply contracts where pricing is negotiated at the supplier level and not publicly disclosed. Recent acquisitions have broadened the revenue base: VOXX International (April 2025, $196 million) contributed $88.6 million of premium-audio and consumer-electronics revenue in Q1 2026, while BioConnect (November 2025) brought a multi-modal biometric authentication software platform serving 1,500+ customers in healthcare, finance, and data storage. Earlier-moved adjacencies include the eSight wearable vision-enhancement business (January 2024), the EyeLock iris biometric hardware line, the PLACE smart-home safety system, and the long-standing Fire Protection Products Group. The company returned $425.9 million to shareholders in 2025 through buybacks and dividends, has maintained a $0.12 quarterly dividend for 24 consecutive years, and operates sales/engineering subsidiaries across the US, Canada, France, Germany, the UK, Sweden, China, Japan, and Korea.
