Gentex’s main products are rearview mirrors that darken automatically to reduce glare. They use the company’s proprietary electrochromic technology and can incorporate displays, cameras and other vehicle electronics. Gentex manufactures these products and sells them globally to automakers and their suppliers. Automotive products generate the vast majority of its revenue.
Toyota, Volkswagen Group and General Motors are each major customers, buying directly or through their suppliers. Annual purchase orders generally set prices for a vehicle model without specifying quantities, so sales depend on how many vehicles customers build and which Gentex features they install. Gentex manufactures primarily in the United States, and tariffs have hindered its exports to China.
The acquisition of VOXX added a smaller premium-audio business. Gentex makes and distributes products such as speakers, receivers and home-theater systems, selling them through retailers and distributors and to cinema operators.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Gentex depends on light-vehicle output and adoption of mirror features, so also watch Volkswagen Group, absent from this list but responsible for 11% of its 2025 sales.
Magna International both competes with Gentex for automakers’ mirror business and pays Gentex for exterior mirror assemblies that automatically darken to reduce glare. Watch Magna’s mirror business within Power & Vision: it is both a rival and an outlet for Gentex products.
Toyota Motor Corporation’s vehicle production matters directly to Gentex: the automaker buys its mirrors and electronics directly and through suppliers that deliver systems to Toyota, accounting for 18% of Gentex’s 2025 sales. Toyota production cuts would put that revenue at risk.
General Motors buys Gentex mirrors and electronics directly and through its system suppliers, making the automaker responsible for 10% of Gentex’s 2025 sales. Watch GM’s vehicle production, including its core full-size trucks and SUVs, for pressure on that customer revenue.
Visteon and Gentex both depend on how many vehicles automakers build and how much electronics they fit into each: Visteon sells cockpit electronics and displays, while Gentex sells electronic mirrors and connected-car features. Visteon’s display and infotainment sales offer a read on automakers’ demand for in-car electronics, rather than mirror demand itself.
Aptiv competes with Gentex for automakers’ safety, sensing and in-cabin electronics orders, selling sensors, driver-assistance systems and infotainment where Gentex offers mirror cameras and other cabin electronics. Watch Aptiv’s safety and user-experience business for competition in these electronics, not just Gentex’s core mirrors.
Gentherm Inc and Gentex share exposure to automaker production and adoption of premium features: Gentherm sells climate-controlled seats and comfort systems, while Gentex sells advanced mirrors. Gentherm’s automotive comfort sales, rather than its medical temperature-management business, are the relevant gauge of that feature demand.
Lear and Gentex face the same vehicle-production cycle and automaker purchasing pressure; Lear sells seats and electrical systems to automakers and also competes in Gentex’s automotive electronics markets. Its E-Systems sales are the closer comparison for Gentex’s electronics business than its seating sales.
Autoliv and Gentex both rely on automakers’ vehicle output: Autoliv sells airbags and seatbelts, while Gentex sells mirrors and electronics that improve visibility. Autoliv’s airbag and seatbelt sales provide a view of the same production cycle, though safety content per vehicle also affects its results.
Stellantis buys Gentex mirrors and electronic modules, tying Gentex orders to a vehicle business with substantial North American and European exposure. Watch Stellantis production in those regions, which are also primary markets for Gentex.
General Motors Company earningsGM
General Motors' report will show whether its vehicle production supports purchases of Gentex mirrors and electronics; GM accounted for 10% of Gentex's 2025 sales.
Watch GM's vehicle production, especially full-size trucks and SUVs, and whether its business strengthens or weakens alongside that production. More output would support orders for Gentex from GM and its system suppliers; less would put that customer-linked revenue under pressure. GM's results alone cannot establish that Gentex has already recorded corresponding sales.
VISTEON CORPORATION earningsVC
Visteon's display and infotainment sales will show automakers' demand for in-car electronics, a market Gentex also serves with electronic mirrors and vehicle electronics.
Focus on Visteon's display and infotainment sales, not its overall results as a proxy for mirror demand. Stronger sales would suggest automakers are supporting purchases of in-car electronics, a favorable demand setting for Gentex's vehicle electronics too. Weaker sales would point to pressure on that electronics demand, but would not establish that Gentex mirror orders are falling as well.
Gentex Corp earningsThis company
Gentex's report will show whether sales of automotive mirrors and electronics, along with cost savings, can absorb pressure from tariffs and customer price cuts.
Read automotive sales alongside gross margin. Steady sales and margin would show Gentex is maintaining shipments while purchasing savings and operating efficiencies offset some tariff costs and customer price pressure; weaker sales or margin would show demand or pricing pressure is outweighing those savings. Then compare total sales with automotive sales: if the gap mainly reflects VOXX-related business, consolidated growth would not mean Gentex's established automotive business has strengthened.
Durable Goods Orders MoM (Sep)
Durable goods orders track purchases of long-lasting goods and equipment; stronger vehicle orders can support production and demand for Gentex’s mirrors and electronics, which it sells to automakers and their Tier 1 suppliers.
Expected0.2%Last release-0.1%
If it comes in above expectations
If the reading is above the 0.2% estimate, it is above the previous -0.1%. More orders point to stronger demand for manufacturers and business investment, which may support vehicle production and automakers’ and Tier 1 suppliers’ demand for Gentex’s mirrors and electronics.
If it comes in below expectations
Fewer orders point to weaker demand, which may weigh on vehicle production and reduce automakers’ and Tier 1 suppliers’ demand for Gentex’s mirrors and electronics.
Magna International earningsMGA
Magna International's Power & Vision mirror business competes with Gentex for automaker programs and buys Gentex's auto-dimming exterior mirror assemblies, so its report bears on both demand and rivalry.
Focus on Magna's mirror business within Power & Vision, not just its total sales. Strength that reflects healthy mirror-program demand could support Magna's purchases of Gentex auto-dimming exterior mirror assemblies. But Magna also competes for automaker programs, so growth from winning those programs could squeeze Gentex's orders. Weakness would point to pressure on mirror programs, but would not by itself show that Gentex is benefiting.
Toyota Motor Corporation earningsTM
Toyota Motor's report will show whether its vehicle production supports purchases of Gentex mirrors and electronics; Toyota accounted for 18% of Gentex's 2025 sales.
Watch Toyota's vehicle production and whether its business strengthens or weakens alongside it. More output would support orders for Gentex from Toyota and its suppliers; less would put that customer-linked revenue under greater pressure. Toyota accounted for 18% of Gentex's 2025 sales, but Toyota's results cannot establish that Gentex has already recorded corresponding sales.
