                      GENTEX REPORTS FIRST QUARTER RESULTS

         ZEELAND, Michigan, April 20, 2006 -- Gentex Corporation, the Zeeland,
Michigan-based manufacturer of automatic-dimming rearview mirrors and commercial
fire protection products, today reported financial results for the first quarter
ended March 31, 2006. The Company also announced that it repurchased
approximately 2.8 million shares during the first quarter of 2006 under a
previously authorized share repurchase plan.

         The Company's net sales increased by nine percent from $127.6 million
in the first quarter of 2005 to a record $139.0 million in the first quarter of
2006. First quarter net income increased by two percent to $26.4 million
compared with $25.9 million in the first quarter last year. Earnings per diluted
share were 17 cents in the first quarter of 2006 compared with 17 cents in the
first quarter of 2005.

         "We are pleased to report solid financial results in what continues to
be a very challenging automotive industry environment," said Gentex Chairman of
the Board and Chief Executive Officer Fred Bauer.

         For the first quarter of 2006, the Company's Statements of Income
reflected stock option expense for the first time. Excluding the impact of stock
option expensing, the Company's net income would have increased by five percent
to $27.3 million, and earnings per diluted share would have been 18 cents, for
the first quarter of 2006. Stock option expense had previously not impacted the
Company's income statement but had been disclosed in a footnote to the financial
statements.

         "Stock option expensing negatively impacted our earnings per share by
about one cent during the first quarter of 2006, and our expectation is that it
will have a similar effect in each quarter for the rest of this calendar year,"
said Gentex Senior Vice President and Chief Financial Officer Enoch Jen.

         Jen said that the Company chose to include non-GAAP (generally accepted
accounting principles) earnings in an effort to provide clearer information to
investors who will compare certain 2006 first quarter line items including stock
option expenses to those same line items in 2005, when stock option expense was
not reflected in the Company's financial statements. He said that providing the
non-GAAP information should present a clearer picture of the Company's operating
performance on a comparative year-over-year basis.

         The Company also reported that it repurchased approximately 2,804,000
shares during the first quarter of 2006 at a cost of approximately $47.1
million. The Company has a share repurchase plan in place with authorization to
repurchase up to 8 million shares of the Company's stock. To date, including the
prior share repurchases in 2003 and 2005, the Company has repurchased
approximately 5,130,000 shares, leaving approximately 2,870,000 shares
authorized to be repurchased under the plan.

         "While our unit shipment growth was higher than we had forecasted for
the quarter, the average selling price of our auto-dimming mirrors was lower
than expected due to product mix," said Jen. "We shipped more base feature
mirrors to certain European and Asian customers during the quarter than we had
forecasted. In addition, a high-volume, advanced-feature mirror program for a
number of models at a European customer has been delayed until the third
quarter, and we will continue to ship base mirror sub-assemblies for those
models until the new contented mirror programs begin to ramp up."



         During the first quarter ended March 31, 2006, the Company's gross
margin declined on both a year-over-year and sequential basis, primarily due to
customer price reductions and higher fixed overhead expense.

          "In summary, with the lower sales dollars associated with mirror unit
shipments, we were not able to spread our fixed overhead costs over a higher
revenue base," said Jen. "We continue to hope that we'll be able to leverage our
fixed manufacturing overhead costs beginning in the second half of this year. We
currently expect unit shipment growth in the second quarter of approximately ten
percent compared to the second quarter of 2005, and a similar rate of growth for
all of calendar year 2006."

         Jen said that there continues to be a great deal of uncertainty in the
automotive industry, making it more difficult for companies to accurately make
unit sales forecasts. In addition, higher interest rates and oil prices are
impacting the sales of vehicles, especially in the large truck/SUV segment,
which is a vehicle segment for which the Company has historically shipped highly
contented interior mirrors in relatively high volumes.

         The unit shipment estimates provided by the Company for the 2006 second
quarter and calendar year are based on the flat to slightly increased light
vehicle production forecasts of CSM Worldwide for North America, Europe, Japan
and Korea.

         Automotive revenues increased by nine percent to $133.2 million in the
first quarter of 2006 compared with the same period last year. Fire Protection
revenues increased two percent to $5.8 million for the first quarter of 2006
compared with the first quarter of 2005.

         Total auto-dimming mirror unit shipments in the first quarter were
approximately 3.4 million, a 12 percent increase over the same period last year.

         Auto-dimming mirror unit shipments to customers in North America
increased by seven percent to approximately 1.6 million in the first quarter of
2006 compared with the same quarter last year. North American light vehicle
production increased by five percent in the first quarter of 2006 compared with
the same period in 2005.

         Unit shipments to offshore customers increased by 16 percent to
approximately 1.8 million in the first quarter of 2006 compared with the same
period in 2005. The growth in offshore unit shipments is primarily attributable
to increased vehicle penetration in Europe. Light vehicle production in Europe
increased by three percent in the first quarter of 2006 and by four percent for
Japan and Korea in that same period, compared with the same prior year periods.

Non-GAAP Financial Measure
- --------------------------

         The financial information provided, including earnings, is in
accordance with GAAP. Still, the Company believes it is useful to provide
non-GAAP earnings to exclude the effect of FAS 123(R). This non-GAAP financial
measure allows investors to evaluate current performance in relation to historic
performance without considering this non-cash charge.

         The Company's management uses this non-GAAP information internally to
help assess performance in the current period versus prior periods. Disclosure
of non-GAAP earnings to exclude the effect of FAS 123(R) has economic substance
because the excluded expenses do not represent current or future cash
expenditures.

         A reconciliation of non-GAAP earnings, to exclude the effect of FAS
123(R), to GAAP earnings can be found in the attached financial table. The use
of non-GAAP earnings is intended to supplement, not to replace, presentation of
GAAP earnings. Like all non-GAAP financial measures, non-GAAP earnings are
subject to inherent limitations because all of the expenses required by GAAP are
not included. The limitations are compensated by the fact that non-GAAP earnings
are not relied on exclusively, but are used to simply supplement GAAP earnings.
