              GENTEX REPORTS SECOND QUARTER REVENUES AND NET INCOME

         ZEELAND, Michigan, July 20, 2005 -- Gentex Corporation, the Zeeland,
Michigan-based manufacturer of automatic-dimming rearview mirrors and commercial
fire protection products, today reported second quarter revenues and net income
for the quarter ended June 30, 2005. The Company also announced that the
Executive Committee of the Board of Directors has authorized an increase in the
price at which the Company may repurchase shares under the existing share
repurchase plan. In a separate announcement, the Company reported that BMW will
offer the Company's new SmartBeam technology on three vehicle models beginning
this fall.

         The Company reported quarterly revenues of $132.4 million, a two
percent increase over revenues of $129.6 million reported in the second quarter
last year. Second quarter net income of $26.0 million decreased by ten percent
compared with net income of $29.0 million in the comparable 2004 quarter.
Earnings per diluted share were 17 cents in the second quarter of 2005 compared
with 18 cents in the second quarter of 2004. All per share data reflect the
two-for-one stock split effected in the form of a 100 percent common stock
dividend that became effective on May 9, 2005.

         For the first six months of 2005, the Company posted net income of
$52.0 million on revenues of $260.0 million, compared with net income of $58.8
million on revenues of $259.0 million for the same period in 2004. Earnings per
diluted share were 33 cents for the first six months of 2005 compared with 37
cents for the same period in 2004.

         Mirror unit shipments in North America in the second quarter increased
by one percent while light vehicle production in that market declined by two
percent, as lower unit shipments to the "Detroit 3" automakers were more than
offset by shipments to the Asian and European transplants in North America. Due
to high inventories of certain domestic full-sized sport-utility vehicles
throughout most of the second quarter, production of those vehicles was lower
than forecasted. In addition, the Company experienced a few short-term new
program delays during the second quarter, and sales to certain tier one mirror
customers were lower than expected as those customers made adjustments by
reducing inventories at the end of the quarter.

         "While the new vehicle sales incentive programs currently being offered
by the 'Detroit 3' automakers are moving vehicles off the lots and reducing auto
dealer inventories, Gentex benefits only when production increases on the
vehicles offering our mirror products. This did not, for the most part, happen
with those customers during the second quarter," said Garth Deur, Gentex
executive vice president. "And, while it is difficult for us to anticipate, it
is not unusual for tier one exterior mirror customers to reduce their own
inventories near the end of a model year, which impacted our shipments during
this quarter."

         The Company reported a somewhat weaker than expected gross margin in
the second quarter, which was primarily attributable to lower unit shipment
growth resulting in reduced capacity utilization.

         Total auto-dimming mirror unit shipments for the second quarter of 2005
increased by three percent to 3,095,000 units, compared with 3,001,000 units for
the same quarter in 2004. Total automotive revenues in the second quarter of
2005 increased by two percent to $126.1 million, compared with the same quarter
last year.



         Total auto-dimming mirror unit shipments for the first six months of
2005 increased by two percent to 6,125,000 units, compared with 5,983,000 units
for the same period in 2004. Total automotive revenues were approximately flat
for the first six months of 2005 at $248.1 million, compared with $247.6 million
in the same period in 2004.

         Auto-dimming mirror unit shipments to offshore customers increased by
five percent in the second quarter of 2005 compared with the second quarter of
2004. Light vehicle production declined by one percent in Europe and the Japan
and Korean markets in the second quarter of 2005 compared with the same quarter
last year.

         For the first six months of 2005, auto-dimming mirror unit shipments to
offshore customers increased by six percent compared with the same prior year
period. When comparing those same periods, auto-dimming mirror unit shipments in
North America declined by two percent. During the first six months of 2005,
light vehicle production was flat in Europe and increased by two percent in the
Japan and Korean markets, compared with the first six months of 2004. Light
vehicle production in North America decreased by three percent for the first six
months of 2005 compared with the same period last year.

         For the third quarter of 2005, the Company estimates that the growth in
mirror unit shipments will be in the range of five to ten percent compared with
the third quarter of 2004. For the fourth quarter of 2005, unit shipments are
estimated to increase by approximately ten to 15 percent compared with the same
prior-year period.

         Revenues in the Company's Fire Protection Products Group increased by
eight percent in the second quarter of 2005 to $6.3 million, compared with the
second quarter last year. For the first six months of 2005, fire protection
revenues increased by five percent to $11.9 million.

         The Company also announced today that the Executive Committee of the
Board of Directors has authorized an increase in the price at which the Company
may repurchase shares under the existing share repurchase plan. The current
share repurchase plan was announced by the Company in October 2002, and
authorizes the repurchase of up to eight million (split adjusted) shares based
on a number of factors, including market conditions, the market price of the
Company's common stock, anti-dilutive effect on earnings, available cash and
other factors as the Company deems appropriate. Under this plan, the Company
repurchased 830,000 shares in the first quarter of 2003. The Company does not
intend to provide the price at which it will repurchase shares, except as
required in its quarterly Form 10-Q.

         In a separate announcement, the Company today reported that BMW will
offer the Company's new SmartBeam high-beam headlamp technology on the 5 Series,
6 Series and 7 Series beginning this fall in Europe and other selected regions.
SmartBeam will be offered in conjunction with Xenon headlamps on those vehicle
models. SmartBeam is the intelligent high-beam headlamp control product
developed by the Company that was introduced in the North American market on
several vehicles for the 2005 and 2006 model years.
