Gentex Corporation shares fell to a reported 52-week low of $20.31 after the Company reported third quarter 2026 financial results showing net sales of $647.7 million and diluted EPS of $0.43, missing analyst consensus estimates of roughly $670 million in revenue and $0.50 per share. Reported sales declined from $655.2 million in the prior year, while gross margin decreased to 33.4% from 34.4%. In a Form 8-K filed on October 23, 2026, the Company disclosed that revenue for the quarter was approximately $35 million below its forecast at the beginning of the quarter due to certain customer issues and delayed launches in the quarter. The Company also cited a 10% decrease in mirror unit shipments, impairment charges, and ongoing tariff and pricing pressure. The Company updated its 2026 revenue guidance to approximately $2.65 billion, down from its prior range of $2.65-$2.75 billion. In earlier earnings commentary, Steve Downing, President and CEO, stated: "For the third quarter of 2024, the company reported net sales of $608.5 million compared to net sales of $575.8 million in the third quarter of last year." The investigation concerns whether Gentex Corporation adequately disclosed customer issues, product launch delays, and mirror unit shipment reductions ahead of its third quarter financial release on October 23, 2026.
