ZEELAND, MI--(Marketwire - August 19, 2008) - Gentex Corporation (NASDAQ: GNTX), the Zeeland, Michigan-based manufacturer of automatic-dimming automotive rearview mirrors and commercial fire protection products, today announced that its Board of Directors approved a five percent increase in its quarterly cash dividend rate from $0.105 (10 1/2 cents) to $0.11 (11 cents) per share. The Board subsequently declared a quarterly cash dividend of $0.11 per share that will be payable October 17, 2008, to shareholders of record of the common stock at the close of business on October 7, 2008. The ex-dividend date is October 3, 2008. Due to the required period of time for the settlement of stock trades, this means that a holder must have purchased shares of Gentex common stock on or before October 2, 2008, in order to receive this cash dividend.

"Despite the poor macro environment, and tough automotive industry conditions, Gentex is globally diversified and continues to do well on an operating basis," said Gentex Chairman of the Board and Chief Executive Officer Fred Bauer. "We continue to believe that our policy of increasing the cash dividend, at a rate generally in line with the Company's net income and operating cash flow, is an appropriate way to return cash to the Company's shareholders based on the current U.S. tax laws."
