GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (1) The unaudited condensed consolidated financial statements included herein have been prepared by the Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although the Registrant believes that the disclosures are adequate to make the information presented not misleading. It is suggested that these unaudited condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Registrant's 2004 annual report on Form 10-K. (2) In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only a normal and recurring nature, necessary to present fairly the financial position of the Registrant as of March 31, 2005, and the results of operations and cash flows for the interim periods presented. (3) Inventories consisted of the following at the respective balance sheet dates: March 31, 2005 December 31, 2004 -------------- ----------------- Raw materials $ 19,162,723 $ 18,102,873 Work-in-process 3,814,658 3,894,864 Finished goods 8,661,189 8,603,052 -------------- ------------------ $ 31,638,570 $ 30,600,789 ============== ================= (4) All earnings per share amounts, weighted daily average of shares of common stock outstanding, common stock, and additional paid-in capital have been restated, to reflect the Company's announcement on April 1, 2005, of a two-for-one stock split effected in the form of a 100 percent common stock dividend for each outstanding share, to be issued to shareholders on May 6, 2005. The ex-dividend date will be May 9, 2005.

The Company accounts for these plans under the recognition and measurement principles of APB Opinion No. 25 (Accounting for Stock Issued to Employees) and related interpretations. No stock-based employee compensation cost is reflected in net income, since options granted under these plans have an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation," to stock-based employee compensation. -5-

As a result of the vesting acceleration, approximately 2.3 million shares became immediately exercisable and an additional approximate $13.6 million of proforma stock-based employee compensation expense was recognized in the current quarter. In addition, the Company has also requested shareholder approval of an amendment to its Employee Stock Option Plan to allow the grant of non-qualified stock options. The objectives of these Company actions is primarily to avoid recognizing compensation expense associated with these options in future financial statements, under the Company's adoption of SFAS No. 123(R). (7) Comprehensive income reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. For the Company, comprehensive income represents net income adjusted for items such as unrealized gains and losses on investments and foreign currency translation adjustments. Comprehensive income was as follows: March 31, 2005 March 31, 2004 -------------- -------------- Quarter Ended $ 23,788,586 $ 31,397,263 (8) The increase in common stock during the quarter ended March 31, 2005, was attributable to the issuance of 112,623 shares of the Company's common stock under its stock-based compensation plans. The Company has also recorded a $0.17 per share cash dividend in the first quarter. The first quarter dividend of approximately $13,256,000, was declared on March 3, 2005, and was paid on April 21, 2005.

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONT.) (10) On December 16, 2004, the Financial Accounting Standards Board (FASB) issued SFAS Statement No. 123(R), "Share-Based Payment," which required all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values, and was effective for public companies for interim or annual periods beginning after June 15, 2005. On April 14, 2005, the U.S. Securities and Exchange Commission announced that companies will be allowed to implement SFAS No. 123(R) at the beginning of their next fiscal year after June 15, 2005. The Company does not intend to adopt a fair-value based method of accounting for stock-based employee compensation until required (January 1, 2006). Proforma quarterly earnings and certain Company actions taken in response to SFAS No. 123(R) are disclosed in Note 5 of this quarterly statement. - 7 -

GENTEX CORPORATION AND SUBSIDIARIES ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION RESULTS OF OPERATIONS: FIRST QUARTER 2005 VERSUS FIRST QUARTER 2004 Net Sales. Net sales for the first quarter of 2005 decreased by approximately $1,686,000, or 1%, when compared with the first quarter last year. Net sales of the Company's automotive auto-dimming mirrors decreased by approximately $1,772,000, or 1%, in the first quarter of 2005, when compared to the first quarter last year, primarily due to price reductions granted to automakers and a shift in mirror product mix, despite a 2% increase in auto-dimming mirror unit shipments from approximately 2,982,000 in the first quarter of 2004 to 3,030,000 in the current quarter. This unit increase reflected the increased penetration of interior auto-dimming mirrors on 2005 model year vehicles during the first quarter of 2005. Unit shipments to customers in North America for the current quarter decreased by 4% compared with the first quarter of the prior year, primarily due to lower light vehicle production levels at certain North-American-based automakers. Mirror unit shipments for the current quarter to automotive customers outside North America increased by 7% compared with the first quarter in 2004, primarily due to increased mirror shipments to European automakers as a result of increased penetration. Net sales of the Company's fire protection products increased 2% for the current quarter, despite a weak commercial construction market. Cost of Goods Sold. As a percentage of net sales, cost of goods sold increased from 57.6% in the first quarter of 2004 to 62.4% in the first quarter of 2005. This percentage increase primarily reflected automotive customer price reductions, higher fixed overhead expenses and manufacturing inefficiencies due to unscheduled customer plant shutdowns. Each factor is estimated to have impacted cost of goods sold as a percentage of net sales by approximately 1-2 percentage points. Operating Expenses. Engineering, research and development expenses for the current quarter increased approximately $534,000, from 5.8% to 6.2% of net sales, when compared with the same quarter last year, primarily reflecting additional staffing, engineering and testing for new product development, including mirrors with additional electronic features. Selling, general and administrative expenses increased approximately $95,000, for the current quarter, from 5.2% to 5.4% of net sales, when compared with the first quarter of 2004. This increased expense primarily reflected the continued expansion of the Company's overseas sales and engineering offices, partially offset by a reduction in state taxes. Total Other Income. Total other income for the current quarter increased by approximately $1,149,000 when compared with the first quarter of 2004, primarily from increased interest income due to higher interest rates and realized gains on the sale of equity investments. Income Taxes. The Company's effective income tax rate decreased from 32.5% in the first quarter of 2004 to 31.5% in the first quarter of 2005, primarily due to a higher tax benefit from increased overseas sales. FINANCIAL CONDITION: Cash flow from operating activities for the three months ended March 31, 2005, increased $771,000 to $42,735,000, compared to $41,965,000, for the same period last year, primarily due to lower growth in accounts receivable, partially offset by decreased net income. Capital expenditures for the three months ended March 31, 2005, increased to $11,129,000, compared to $6,319,000 for the same period last year, primarily due to new facility construction. The Company currently expects that the construction of its fourth automotive manufacturing facility and a new technical center will be completed in spring 2006. The Company plans to invest approximately $35-40 million for the new facilities during 2004-2006, which will be funded from its cash and cash equivalents on hand. Cash and cash equivalents as of March 31, 2005, increased approximately $30,811,000 compared to December 31, 2004. The increase was primarily due to cash flow from operations, less dividends paid. Accrued liabilities as of March 31, 2005, increased $16,490,000, compared to December 31, 2004. The increase was primarily due to the timing of estimated federal income tax payments. - 8 -

Management considers the Company's working capital and long-term investments totaling approximately $671,171,000 as of March 31, 2005, together with internally generated cash flow and an unsecured $5,000,000 line of credit from a bank, to be sufficient to cover anticipated cash needs for the next year and for the foreseeable future. On October 8, 2002, the Company announced a share repurchase plan, under which the Company may purchase up to 4,000,000 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 that the Company deems appropriate. During the quarter ended March 31, 2003, the Company repurchased 415,000 shares at a cost of approximately $10,247,000. No shares have been repurchased subsequently by the Company. TRENDS AND DEVELOPMENTS: During the first quarter of 2005, the Company negotiated an extension to its long-term agreement with General Motors in the ordinary course of the Company's business. Under the extension, Gentex will be sourced all of the interior auto-dimming rearview mirrors programs for GM and its worldwide affiliates through August 2009, and includes all but two low-volume models that had previously been awarded to a Gentex competitor under a lifetime contract. The new business also includes the GMT360 program, which is the mid-size truck/SUV platform that currently does not offer auto-dimming mirrors. The new GM programs will be transferred to Gentex by no later than the 2007 model year. We currently estimate that this new business represents incremental auto-dimming mirror units in the range of 500,000 on an annualized basis. The Company also negotiated a price reduction for the GM OnStar feature in its auto-dimming mirrors, effective January 1, 2005, in connection with GM's plan to make their OnStar system standard across their vehicle models over the next several years. The Company currently expects that auto-dimming mirror unit shipments will be 5-10% higher in the second quarter of 2005 compared with the second quarter of 2004, and that mirror unit shipments will increase approximately 10% for calendar 2005 compared with calendar 2004. These estimates are based on light vehicle production forecasts in the regions to which the Company ships product, as well as the estimated option rates for its mirrors on prospective vehicle models. The Company utilizes the light vehicle production forecasting services of CSM Worldwide, and CSM's current forecasts for light vehicle production for calendar 2005 are approximately 15.8 million units for North America, 20.5 million for Europe and 13.1 million for Japan and Korea. The Company is subject to market risk exposures of varying correlations and volatilities, including foreign exchange rate risk, interest rate risk and equity price risk. During the quarter ended March 31, 2005, there were no significant changes in the market risks reported in the Company's 2004 Form 10-K report. The Company has some assets, liabilities and operations outside the United States, which currently are not significant. Because the Company sells its automotive mirrors throughout the world, it could be significantly affected by weak economic conditions in worldwide markets that could reduce demand for its products. The Company continues to experience pricing pressures from its automotive customers, which have affected, and which will continue to affect, its margins to the extent that the Company is unable to offset the price reductions with productivity improvements, engineering and purchasing cost reductions, and increases in unit sales volume. In addition, profit pressures at certain automakers are resulting in increased cost reduction efforts by them, including requests for additional price reductions, decontenting certain features from vehicles, and warranty cost-sharing programs, which could adversely impact the Company's sales growth and margins. The Company also continues to experience some pressure for select raw material cost increases. Automakers have been experiencing increased volatility and uncertainty in executing planned new programs which have, in some cases, resulted in cancellations or delays of new vehicle platforms, package reconfigurations and inaccurate volume forecasts. This increased volatility and uncertainty has made it more difficult for the Company to forecast future sales and effectively utilize capital, engineering, research and development, and human resource investments. - 9 -

The Company does not have any significant off-balance sheet arrangements or commitments that have not been recorded in its consolidated financial statements. On March 30, 2005, in response to the required implementation of SFAS No. 123(R) as disclosed in Note 10, the Company accelerated the vesting of current "under water" stock options. As a result of the vesting acceleration, approximately 2.3 million shares became immediately exercisable and an additional approximate $13.6 million of proforma stock-based employee compensation expense was recognized in the current quarter. In addition, the Company has also requested shareholder approval of an amendment to its Employee Stock Option Plan to allow the grant of non-qualified stock options. The objectives of these Company actions is primarily to avoid recognizing compensation expense associated with these options in future financial statements, under the Company's adoption of SFAS No. 123(R). On October 1, 2002, Magna International acquired Donnelly Corporation, the Company's major competitor for sales of automatic-dimming rearview mirrors to domestic and foreign vehicle manufacturers and their mirror suppliers. The Company sells certain automatic-dimming rearview mirror sub-assemblies to Magna Donnelly. To date, the Company is not aware of any significant impact of Magna's acquisition of Donnelly upon the Company; however, any ultimate significant impact has not yet been determined. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The information called for by this item is provided under the caption "Trends and Developments" under Item 2 - Management's Discussion and Analysis of Results of Operations and Financial Condition. ITEM 4. CONTROLS AND PROCEDURES As of March 31, 2005, an evaluation was performed under the supervision and with the participation of the Company's management, including the CEO and CFO, of the effectiveness of the design and operation of the Company's disclosure controls and procedures [(as defined in Exchange Act Rules 13a - 15(e) and 15d - 15(e)]. Based on that evaluation, the Company's management, including the CEO and CFO, concluded that the Company's disclosure controls and procedures were adequate and effective as of March 31, 2005, to ensure that material information relating to the Company would be made known to them by others within the Company, particularly during the period in which this Form 10-Q was being prepared. During the period covered by this quarterly report, there have been no changes in the Company's internal controls over financial reporting that have materially affected or are likely to materially affect the Company's internal controls over financial reporting. Statements in this Quarterly Report on Form 10-Q contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act, as amended, that are global automotive industry, the economy and the Company itself, and involve risks and uncertainties described under the headings "Management's Discussion and Analysis of Results of Operations and Financial Condition" and "Trends and Developments." Words like "anticipates," "believes," "confident," "estimates," "expects," "forecast," "likely," "plans," "projects," and "should," and variations of such words and similar expressions identify forward-looking statements. These statements do no guarantee future performance and involve certain risks, uncertainties, and assumptions that are difficult to predict with regard to timing, expense, likelihood and degree of occurrence. These risks include, without limitation, employment and general economic conditions, the pace of economic recovery in the U.S. and in international markets, the pace of automotive production worldwide, the types of products purchased by customers, competitive pricing pressures, currency fluctuations, the financial strength of the Company's customers, the mix of products purchased by customers, the ability to continue to make product innovations, the success of newly introduced products (e.g. SmartBeam), and other risks identified in the Company's filings with the Securities and Exchange Commission. Therefore actual results and outcomes may materially differ from what is expressed or forecasted. Furthermore, the Company undertakes no obligation to update, amend, or clarify forward-looking statements, whether as a result of new information, future events, or otherwise. - 10 -
