GENTEX CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1)    Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements of Gentex Corporation and Subsidiaries ("Gentex" or the "Company") included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission as defined in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 270 for interim financial information, and in accordance with financial standards generally accepted in the United States of America ("GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations, although the Company 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 Company's 2025 annual report on Form 10-K. In the opinion of management, the accompanying Unaudited Condensed Consolidated Financial Statements contain all adjustments considered necessary for a fair presentation of the financial position of the Company as of March 31, 2026, and the results of operations and cash flows for the interim periods presented.

(2)    Adoption of New Accounting Standards

In March 2024, the Securities and Exchange Commission ("SEC") issued Final Rule No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors." If such rule becomes effective, the rule will require disclosure of climate-related information outside of the audited financial statements and disclosure in the footnotes to such financial statements addressing specified financial statement effects of severe weather events and other natural conditions above certain financial thresholds, certain carbon offsets and renewable energy credits or certificates, if material. Such disclosure requirements were scheduled to begin phasing in for fiscal years beginning on or after January 1, 2025. On April 4, 2024, the SEC exercised its discretion to voluntarily stay the effective date of the final rules pending completion of certain judicial review. In 2025, the SEC withdrew its defense of the climate disclosure rules and litigation has been held in abeyance. The SEC has launched a formal review, inviting public comment, with an eye toward facilitating disclosure of consistent, comparable, and reliable information on climate change. Though compliance with such rules is not currently required, and it is unclear when or if compliance will be required, the Company continues to evaluate the potential impact of compliance, as well as compliance with similar rules of other jurisdictions.

In November 2024, the FASB issued ASU No. 2024-03, "Disaggregation of Income Statement Expenses (Subtopic 220-40)." The ASU requires public business entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Companies have the option to apply the guidance either on a retrospective or prospective basis, and early adoption is permitted. In January 2025, the FASB issued ASU No. 2025-01, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date." This ASU amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of adopting these ASU's on the Consolidated Financial Statements and related disclosures.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity ("VIE"), which provides clarifying guidance on determining the accounting acquirer in certain transactions involving VIE's. The update aims to improve consistency and comparability in financial reporting. The guidance will be effective for annual periods beginning after December 15, 2026, including interim periods within those annual periods. Early adoption is permitted. Upon adoption, the guidance will be applied prospectively. The Company is currently evaluating the provisions of the guidance and the impact on its future Consolidated Financial Statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which introduces a practical expedient for the application of the current expected credit loss model to current accounts receivable and contract assets in which all entities can assume that current conditions as of the balance sheet date do not change for the remaining life of the assets. This ASU was effective for the Company in the first quarter of 2026 and did not have a material impact the Company's Consolidated Financial Statements and disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU updates the cost capitalization threshold for internal-use software development costs by removing all references to software project development stages and providing new guidance on how to evaluate whether the probable-to-complete recognition threshold has

been met. ASU 2025-06, which can be applied prospectively, retrospectively, or with a modified transition approach, is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and disclosures.

In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging - Hedge Accounting Improvements (Topic 815), which amends certain aspects of the hedge accounting guidance to better align financial reporting with the economics of an entity's risk management activities. ASU 2025-09 is effective for annual and interim periods beginning after December 15, 2026. Early adoption is permitted and is effective on a prospective basis. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements ("ASU 2025-11"). This ASU enhances consistency in interim reporting for all entities by clarifying interim disclosure requirements and the form and content of interim financial statements in accordance with GAAP. ASU 2025-11, which can be applied prospectively or retrospectively to any and all prior periods presented in the financial statements, is effective for the interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and related disclosures.

(3)    Goodwill and Other Intangible Assets

Goodwill represents the cost of an acquisition in excess of the fair values assigned to identifiable net assets acquired. The change in the carrying value of Goodwill by segment is as follows:

	Amount
Automotive Products
Beginning balance as of January 1, 2026	$	309,709,522
Period activity	—
Balance as of March 31, 2026 (1)	$	309,709,522
Premium Audio Products
Beginning balance as of January 1, 2026	$	12,713,758
Acquisitions (including measurement period adjustments) (see Note 16)	3,765,220
Balance as of March 31, 2026 (1)	$	16,478,978
Other
Beginning balance as of January 1, 2026	$	34,788,639
Foreign currency adjustment	(52,832)
Balance as of March 31, 2026	$	34,735,807
Gross carrying value at March 31, 2026	$	38,400,511
Accumulated impairment charges	(3,664,704)
Net carrying value at March 31, 2026	$	34,735,807
Total Goodwill, net	$	360,924,307
(1) The gross carrying values of goodwill in the Automotive Products and Premium Audio Products segments are equal to their net carrying values as there have been no impairments of goodwill within these segments.

In addition to annual impairment testing, which is performed as of the first day of the Company's fourth quarter, the Company continuously monitors for events and circumstances that could negatively impact the key assumptions in determining fair value of goodwill or other intangible assets, thus resulting in the need for interim impairment testing, including: long-term revenue growth projections; profitability; discount rates; recent market valuations from transactions by comparable companies; volatility in the Company's market capitalization; and general industry, market, and macroeconomic conditions.

During the first quarter of 2026, as a result of costs to develop the Company's In-Process Research and Development ("In Process R&D") continuing to exceed original estimates, as well as delays in the expected timing of commercialization of the related technology, management approved and began executing a plan to cease operations at the facility where its Vaporsens In-Process R&D activities were conducted. This plan included the termination of substantially all employees associated with those activities. As a result, the Company discontinued further development of the underlying technology and shifted its strategy to the potential sale of the related assets. These actions represented a significant adverse change in the extent and manner in which the In-Process R&D was expected to be used and in its projected future cash flows, indicating that the carrying value of the asset may not be recoverable. Accordingly, the Company recorded an impairment charge of $2.8 million during the three months ended March 31, 2026, to reduce the carrying amount of the asset to its estimated fair value. The estimated fair value was determined based on the Company's estimate of the expected selling price of the asset, taking into consideration available market information and indicative third-party interest, as applicable.

Except as set forth, the Company noted no other events or circumstances indicating the need for interim impairment testing of its goodwill or other intangible assets during the first quarter of 2026.

The Company's patents and intangible assets and related change in carrying values are set forth in the tables below, including the Vaporsens In-Process R & D, which has been previously disclosed.

Excluding the impact of any future acquisitions, the Company estimates amortization expense to be approximately $3.5 million for the remainder of the year ending December 31, 2026, $5 million for each of the years ending December 31, 2027, and December 31, 2028, respectively, and $4 million for each of the years ended December 31, 2029, and December 31, 2030, respectively.

(4)    Investments

Available for sale securities

The Company follows the provisions of Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures, for its financial assets and liabilities, and for its non-financial assets and liabilities subject to fair value measurements. ASC 820 provides a framework for measuring the fair value of assets and liabilities. This framework is intended to provide increased consistency in how fair value determinations are made under various existing accounting standards that permit, or in some cases, require estimates of fair-market value. This standard also expanded financial statement disclosure requirements with respect to a company’s use of fair-value measurements, including the effect of such measurements on earnings. The cost of securities sold is based on the specific identification method.

The Company determines the fair value of its asset-backed securities, municipal bonds, and corporate bonds by utilizing monthly valuation statements that are provided by its broker. The broker determines the investment valuation by utilizing the bid price in the market and also refers to third party sources to validate valuations, and as such are classified as Level 2 assets.

The Company's certificates of deposit are classified as available for sale and are considered as Level 1 assets. These investments are carried at cost, which approximates fair value.

Equity Method Investment - ASA

The Company has a 50% non-controlling ownership interest in ASA Electronics, LLC and Subsidiary ("ASA"), that was obtained in conjunction with the acquisition of VOXX International Corporation ("VOXX") on April 1, 2025 (see Note 16) and is accounted for in accordance with ASC 323, Investments – Equity Method and Joint Venture. ASA acts as a distributor of mobile electronics, specifically designed for niche markets, including: RV's; buses; and commercial, heavy duty, agricultural, construction, powersport, and marine vehicles. ASC 810, Consolidation, requires the Company to evaluate non-consolidated entities periodically, and as circumstances change, to determine if an implied controlling interest exists. The balance of the Company's investment in ASA was $20.5 million and $20.0 million as of March 31, 2026 and December 31, 2025, respectively, and included in Long-term investments on the accompanying Unaudited Condensed Consolidated Balance Sheets.

Technology Investments

The Company also periodically makes strategic investments in the non-marketable debt or equity securities of other non-consolidated third parties ("Technology Investments"). Such Technology Investments totaled $146.2 million as of March 31, 2026, and are recorded in long-term investments on the accompanying Unaudited Condensed Consolidated Balance Sheet. Such Technology Investments totaled approximately $146.6 million as of December 31, 2025, of which $144.9 million and $1.7 million are included in long-term investments and short-term investments, respectively, on the accompanying Unaudited Condensed Consolidated Balance Sheets. Depending on the form of investment, and the degree of influence the Company has over the investee, the Company primarily accounts for the Technology Investments in accordance with ASC 321, Investments - Equity Securities or ASC 323, Investments – Equity Method and Joint Venture. The Company accounts for equity securities in non-controlled affiliates through which the Company exercises significant influence but does not have control over the investee under the equity method, with the Company’s share of the earnings or losses of non-controlled affiliates recognized within Other (loss) income, net, in the Company's accompanying Unaudited Condensed Consolidated Statements of Income. All other Technology Investments that the Company holds are primarily accounted for under the measurement alternative of ASC 321. Under the measurement alternative, the carrying value is measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer.

During the three months ended March 31, 2026, the Company recognized a loss of $1.7 million within Other, net, related to warrants held in one of the Company's technology investments that expired unexercised during the quarter.

During the same period, the Company recorded an other-than-temporary impairment charge of $2.7 million related to one of its technology investments, which is included in Investment (loss) income, net, on the accompanying Unaudited Condensed Consolidated Statement of Income. During the first quarter of 2026, the Company identified indicators of impairment related the investment, including a sustained deterioration in the entity's operating results and financial condition, as well as the execution of a forbearance agreement associated with outstanding loans from the Company to the investee totaling approximately $5.0 million (exclusive of credit reserves) as of March 31, 2026. Based on these factors, the Company determined that the decline in fair value of its investment was other-than-temporary. The Company concluded that the estimated fair value of its equity interest was negligible, as the investee's enterprise value was not expected to be sufficient to satisfy the Company's outstanding loan exposure. Accordingly, the Company recorded a full impairment charge to reduce the carrying amount of the investment to zero.

From time to time, the Company makes loans in the ordinary course of business to certain of its technology investees. Such loans vary in length and are interest bearing, and as such are not deemed to be additional investments in the technology investees as the parties intend for the loans to be repaid. These loans are classified within Prepaid expenses and other and Patents and other assets, net, on the accompanying Unaudited Condensed Consolidated Balance Sheets based on the maturity dates of the loans. The Company estimates an allowance for credit losses for these loans receivable in accordance with ASC 326, Financial Instruments - Credit Losses. This allowance reflects the Company's estimate of expected credit losses over the contractual life of the loans, considering historical loss experience, current conditions, and reasonable and supportable forecasts. The estimate is developed using a combination of quantitative data and qualitative factors, including borrower creditworthiness, loan-specific risk characteristics, macroeconomic trends, and other relevant information, all of which is updated quarterly. The allowance is adjusted through a provision for credit losses in the Company's Unaudited Condensed Consolidated Statements of Income. For the three months ended March 31, 2026, the Company recorded an increase to the credit loss allowance of $2.2 million. The total allowance for credit losses attributable to the Company's loans receivable were $9.7 million and $7.4 million at March 31, 2026 and December 31, 2025, respectively. The balance of the loans included in Prepaid expenses and other on the accompanying Unaudited Condensed Consolidated Balance Sheets was $11.9 million and $13.5 million at March 31, 2026 and December 31, 2025, respectively, net of credit loss allowances. The balance of the loans included in Patents and other assets, net, on the accompanying Unaudited Condensed Consolidated Balance Sheets was $7.2 million and $7.9 million, at March 31, 2026 and December 31, 2025, respectively, net of credit loss allowances.

The Company has unvested share-based payment awards with a right to receive non-forfeitable dividends, which are considered participating securities under ASC 260, Earnings Per Share. The Company allocates earnings to participating securities and computes earnings per share using the two-class method. Under the two-class method, net income per share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, net income is allocated to both

(7)    Stock-Based Compensation Plans

As of March 31, 2026, the Company had two equity incentive plans in effect, which include the Gentex Corporation 2019 Omnibus Incentive Plan ("2019 Omnibus Plan"), and an employee stock purchase plan. Those plans and any prior material amendments thereto have previously been approved by shareholders.

The 2019 Omnibus Plan provides for the potential awards to: i) employees; and ii) non-employee directors of the Company or its subsidiaries, which potential awards may be stock options (both incentive stock options and non-qualified stock options), appreciation rights, restricted stock awards and restricted stock units, performance share awards and performance units, and other awards that are stock-based, cash-based or a combination of both. The 2019 Omnibus Plan replaced the Company's Employee Stock Option Plan, Second Restricted Stock Plan, and Amended and Restated Non-Employee Director Stock Option Plan (the "Prior Plans"), which were also approved by shareholders. Any existing awards previously granted under the Prior Plans remain outstanding in accordance with their terms and are governed by the Prior Plans as applicable.

Readers should refer to Note 5 of the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the calendar year ended December 31, 2025, for additional information related to the Prior Plans.

The Company recognized total compensation expense for share-based payments of $10.4 million for the three months ended March 31, 2026, compared to $8.7 million for the three months ended March 31, 2025, respectively. A portion of the compensation cost for share-based payment awards is capitalized as part of inventory.

2019 Omnibus Incentive Plan

The purpose of the 2019 Omnibus Plan is to attract and retain employees, officers, and directors of the Company and its subsidiaries and to motivate and provide such persons' incentives and rewards for performance. Pursuant to the

16

terms of the 2019 Omnibus Plan, each type of award counts against the available shares based on a predetermined conversion rate (shown in the table below). As of March 31, 2026, 13,241,091 share awards have been made under the Plan, resulting in 38,942,701 shares granted of the 45,000,000 total shares available to be issued under the Plan. The shares issued are presented net of shares from canceled/expired options and shares.

Total	13,241,091		38,942,701

Employee Stock Options

Under the 2019 Omnibus Plan and the Employee Stock Option Plan, the option exercise price equals the stock’s market price on the date of grant. The options vest after one to five years and expire after five to ten years. As of March 31, 2026, there was $3.3 million of unearned compensation cost associated with stock options granted under the 2019 Omnibus Incentive Plan and the Employee Stock Option Plan, which is expected to be recognized over the remaining vesting periods.

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions for the indicated periods:

	Three Months Ended March 31,
	2026		2025
Dividend Yield (1)	1.70	%	1.62	%
Expected volatility (2)	25.89	%	25.60	%
Risk-free interest rate (3)	3.92	%	3.96	%
Expected term of options (years) (4)	4.15		4.14
Weighted-avg. grant date fair value	$5.00		$5.35

1.Represents the Company’s estimated cash dividend yield over the expected term of option grant.

2.Amount is determined based on analysis of historical price volatility of the Company’s common stock. The expected volatility is based on the daily percentage change in the price of the stock over a period equal to the expected term of the option grant.

3.Represents the U.S. Treasury yield over the expected term of the option grant.

Restricted shares awarded under the 2019 Omnibus Plan and the Second Restricted Stock Plan entitle the shareholder to all rights of common stock ownership, except that the shares may not be sold, transferred, pledged, exchanged, or otherwise disposed of during the restriction period. The restriction period is determined by the Compensation Committee, appointed by the Board of Directors, but may not exceed ten years under the terms of such plans. As of March 31, 2026, the Company had unearned stock-based compensation of $54.1 million associated with the restricted stock grants issued under the 2019 Omnibus Plan and the Second Restricted Stock Plan. The unearned stock-based compensation related to these grants is being amortized to compensation expense over the applicable restriction periods. Compensation expense from restricted stock grants for the three months ended March 31, 2026 was $6.0 million, compared to $5.9 million for the three months ended March 31, 2025.

Performance Shares

Performance shares awarded under the 2019 Omnibus Plan are considered performance condition awards as attainment is based on the Company's performance relative to pre-established metrics. The fair value of such performance share awards was determined using the Company's average closing stock price on the twenty days preceding the date of grant. The expected attainment of the metrics for these awards is then analyzed each reporting period, and the related expense is adjusted based on expected attainment, if the then expected attainment differs from

(Unaudited)

previous expectations. The cumulative effect on current and prior periods of a change in expected attainment is recognized in the period of change.

As of March 31, 2026, the Company had unearned stock-based compensation of $17.6 million associated with these performance share grants. The unearned stock-based compensation related to these grants is being amortized to compensation expense over the applicable performance periods. Compensation expense related to these performance share grants for the three months ended March 31, 2026 was $2.9 million, compared to $1.0 million for the three months ended March 31, 2025.

As part of its objective of attracting and retaining management to fulfill the Company's strategic goals, the Compensation Committee recommended and the Board approved on February 16, 2023, a retention grant of performance share awards ("PSAs"). In addition to the retention of management, the PSAs have been granted to further align management goals with those of the Company's shareholders. For that reason, the PSAs have been granted with performance criteria and will be based upon achievement of the Company's relative total shareholder return ("TSR") over a four-year period (2023-2026), against a predetermined peer group. The grant date fair value of PSAs with TSR targets was determined using a Monte Carlo simulation. Compensation expense related to these retention grants was $0.5 million during each of the three months ended March 31, 2026 and March 31, 2025.

Employee Stock Purchase Plan

The 2022 Gentex Corporation Employee Stock Purchase Plan covering 2,000,000 shares of common stock was approved by shareholders effective July 1, 2022. Under the plan, the Company sells shares at 85% of the stock's market price at date of purchase. Under ASC 718, Compensation - Stock Compensation, the 15% discounted value is recognized as compensation expense. As of March 31, 2026, the Company has issued 804,112 shares under this plan.

(9)    Debt and Financing Arrangements

The Company has a credit agreement with PNC as the administrative agent and sole lender (the "Credit Agreement"), that provides for, among other things, a three-year unsecured revolving credit facility with a borrowing capacity of up to $350.0 million (the "Revolver"). Included in the Revolver is a $20.0 million sublimit for standby letters of credit and a $35.0 million sublimit for swingline loans, each subject to certain conditions. Funds are available under the Revolver for working capital, capital expenditures, and other lawful corporate purposes, including, but not limited to, acquisitions and common stock repurchases, subject in each case to compliance with certain financial covenants, as defined in the Credit Agreement. The maturity date of the Credit Agreement is October 1, 2028.

The obligations of the Company under the Credit Agreement are not secured, but are subject to certain covenants. The Credit Agreement contains customary representations and warranties and certain covenants that place certain limitations on the Company. As of March 31, 2026, there was no outstanding balance on the Revolver and the Company was in compliance with all covenants under the Credit Agreement.

The Company's subsidiary, VOXX, which was acquired on April 1, 2025 (see Note 16), has a loan agreement with the shareholders of its joint venture in Onkyo Technology KK ("Onkyo"). The loan balance outstanding at March 31, 2026 was $3.8 million and is included in Short-term debt on the accompanying Unaudited Condensed Consolidated Balance Sheet, representing the portion of the loan payable to the joint venture partner. All amounts outstanding under the loan will mature and become payable on September 8, 2031. The loan may be prepaid subject to the approval of the board of directors of the joint venture and must be repaid if either a put or call option is exercised in accordance with the joint venture agreement. The rate of interest for the shareholder loan is 2.5% and the loan is secured by a second priority lien on and secured interest in all assets of Onkyo.

(10)    Equity

The decrease in common stock for the three months ended March 31, 2026, was primarily due to the repurchases of 3.3 million shares, partially offset by the issuance of 0.8 million shares of the Company’s common stock, net of

20

GENTEX CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

cancellations, under the Company’s stock-based compensation plans. The total net decrease for the three months ended March 31, 2026, was 2.5 million shares.

The Company recorded a cash dividend of $0.120 per share during the first quarter of 2026, as compared to a cash dividend of $0.120 per share during the first quarter of 2025. The first quarter 2026 dividend of $25.6 million was declared on February 24, 2026, and was paid on April 22, 2026.

(11)    Contingencies

The Company is periodically involved in legal proceedings, legal actions and claims arising in the normal course of business, including proceedings relating to, for example, product liability, intellectual property, safety and health, employment, regulatory, and other matters. Such matters are subject to many uncertainties and outcomes are not predictable. The Company does not believe, however, that at the current time any of these matters constitute material pending legal proceedings that will have a material adverse effect on the financial position or future results of operations or cash flows of the Company.

On April 1, 2025, the Company completed its acquisition of VOXX (see Note 16). In connection with the acquisition, VOXX as acquired, maintained responsibility for certain legal matters and royalty audits. These matters include legal proceedings in which VOXX was named a defendant prior to the acquisition date, as well as unasserted claims and other legal matters for which the underlying events or circumstances existed as of the acquisition date and for which a liability was required to be recognized under ASC 805, Business Combinations ("ASC 805"). As part of the purchase price allocation, pursuant to applicable guidance, the Company recorded provisional liabilities for these matters based on estimates of their fair values as of the acquisition date. The Company continues to monitor the status of any of the matters that remain unresolved. Any adjustments recognized after the measurement period, as a result of additional information becoming available or the resolution of these matters, will be reflected in earnings in the period in which the adjustment is identified.

On February 20, 2026, the U.S. Supreme Court struck down certain tariffs imposed under the International Emergency Economic Powers Act ("IEEPA"). Following the Supreme Court’s decision, the U.S. administration announced a new 10% global tariff under Section 122 of the Trade Act of 1974, subject to certain exceptions. The impact of these decisions on the Company remains uncertain, including the potential for refunds of IEEPA tariffs previously paid, changes in tariff levels, and/or new tariffs. The ultimate availability, timing, and amount of any potential refunds of IEEPA tariffs remains highly uncertain and is subject to further legal, regulatory, and administrative developments. Consistent with applicable GAAP, the Company has not recognized any receivable and corresponding offset to expense or asset as of March 31, 2026 related to potential refunds of IEEPA tariffs since any realization of any such recovery is dependent on uncertain future events and the Company is unable to conclude that recovery is both probable and reasonably estimable as of March 31, 2026. The Company continues to monitor and evaluate these developments and assess their potential impact on the Company’s business, financial condition, and results of operations. The Company is pursuing refunds as it determines appropriate.

(12)    Segment Reporting

ASC 280, Segment Reporting, requires that a public business entity report financial and descriptive information about its reportable operating segments, subject to certain aggregation criteria and quantitative thresholds. Operating segments are defined by ASC 280 as components of a public business entity about which separate financial information is available that is evaluated regularly by the chief operating decision-maker ("CODM") in deciding how to allocate resources and in assessing performance. The Company's CODM is its Chief Executive Officer. The CODM evaluates performance and allocates resources based upon a number of factors, including the nature of the business, relevant industry, and profitability of the same, with the primary profit measure being income (loss) from operations of each segment. The CODM uses this information to evaluate the profitability of the Company's reportable segments and make decisions on future business plans.

The Company has identified nine distinct operating segments based on its products and internal organizational structure. These operating segments are disclosed by the Company under three reportable segments for financial reporting purposes, which are Automotive Products, Premium Audio Products, and Other. The Company's Automotive Products segment develops and manufactures digital vision and connected car products and electronics, including: interior and exterior electrochromic automatic-dimming rearview mirrors with and without electronic features; non-auto dimming rearview mirrors with and without electronic features; and other automotive electronics. The Company's Premium Audio Products segment designs, manufactures, markets, and distributes high quality audio equipment created to deliver superior sound quality and performance, including premium loudspeakers, architectural speakers,

21

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

commercial and cinema speakers, outdoor speakers, wireless and Bluetooth speakers, A/V receivers, home theater systems, soundbars, and music streaming systems. The Company's Other segment includes the operating segments of Fire Protection, Dimmable Aircraft Windows, Nanofiber, Medical, Aftermarket, Consumer Electronics, and Biometrics, which do not meet quantitative thresholds for separate disclosure pursuant to ASC 280.

The segments share many common resources, infrastructures, and assets in the normal course of business. Thus, the Company does not report assets or capital expenditures by segment to the CODM.

The following table presents net sales and the significant expense categories for the three months ended March 31, 2026 and 2025 (which did not include VOXX), respectively, that are included in reportable segment operating profit, which are regularly provided to the CODM:

Sales Incentives

Sales incentives are offered to certain customers in the form of: (1) co-operative advertising allowances; (2) market development funds; (3) volume incentive rebates; and (4) other trade allowances. The Company accounts for sales incentives in accordance with ASC 606 "Revenue from Contracts with Customers" ("ASC 606"). These sales incentives represent variable consideration provided to customers. Depending on the specific facts and circumstances, either the most likely amount or expected value methods are utilized to estimate the effect of uncertainty on the amount of variable consideration to which the Company would be entitled. The most likely amount method considers the single most likely amount from a range of possible consideration amounts, while the expected value method is the sum of the probability-weighted amounts in a range of possible consideration amounts. Both methods are based upon the contractual terms of the incentives and historical experience with each customer. Except for other trade allowances, all sales incentives also require the customer to purchase the Company's products during a specified period of time. All sales incentives require customers to claim the sales incentive within a certain time period (referred to as the "claim period") and claims are settled either by the customer claiming a deduction against an outstanding account receivable or by the customer requesting a cash payout. All costs associated with sales incentives are classified as a reduction of net sales. Although the Company makes its best estimate of such sales incentive liability, many factors, including significant unanticipated changes in the purchasing volume of its customers and the lack of claims made by customers, could have a significant impact on the sales incentives liability and reported operating results. The balance of accrued sales incentives at March 31, 2026 and December 31, 2025 was $15.0 million and $19.1 million, respectively, and is included within Accrued liabilities on the Unaudited Condensed Consolidated Balance Sheets.

(15)    Leases

The Company has operating leases for certain sales, manufacturing, and engineering offices, as well as other vehicles and equipment, which are included within Patents and other assets, net on the Unaudited Condensed Consolidated Balance Sheets. The leases have remaining lease terms of less than 1 year to 6 years. The weighted average

remaining lease term for operating leases as of March 31, 2026 was 2 years, with a weighted average discount rate of 4.6%.

BioConnect Inc.

On July 1, 2025, in the ordinary course of business, the Company completed its acquisition of BioConnect Inc. ("BioConnect"), for a purchase price of $13.0 million, subject to adjustment for working capital plus related transaction fees and expenses. BioConnect is a multi-modal biometric authentication platform provider for access control. The Company intends to utilize the acquisition to expand its reach in the biometric industry. The acquisition was accounted for under the acquisition method of accounting pursuant to ASC 805, Business Combinations ("ASC 805"), and accordingly, the results of operations and cash flows for BioConnect have been included in the Company's Unaudited Condensed Consolidated Financial Statements since July 1, 2025. BioConnect's results of operations are included within the Company's Biometrics operating segment, which is presented within its Other reportable segment.

The purchase price allocation above is preliminary. The preliminary fair values of the assets acquired were estimated with the assistance of a third-party valuation expert. The Company is in the process of refining the valuation of acquired assets and assumed liabilities, including net working capital and intangible assets, and expects to finalize the purchase price allocation no later than one year after the acquisition date, which is July 1, 2026, in accordance with applicable guidance. Finalization of the valuation during the measurement period could result in significant changes in the amounts recorded for the acquisition date fair value. The Company recorded net measurement period adjustments increasing goodwill $0.4 million during the fourth quarter of 2025, relating primarily to revised fair value estimates of developed technology and deferred tax assets. The goodwill recognized in this acquisition is primarily attributable to the assembled workforce and expected synergies from the integration of the acquired business. All of the goodwill acquired in connection with the BioConnect acquisition has been allocated to the Company's biometrics business. None of the goodwill from the BioConnect acquisition is deductible for tax purposes.

Net sales attributable to BioConnect in the Company's Unaudited Condensed Consolidated Statement of Income for the three months ended March 31, 2026, were $2.4 million. Net income attributable to BioConnect for the three months ended March 31, 2026, was $0.4 million. There were no acquisition costs incurred during the three months ended March 31, 2026, or March 31, 2025, related to this acquisition.

VOXX International Corporation

On April 1, 2025 (the "Closing Date"), the Company completed its acquisition of VOXX pursuant to the previously announced Merger Agreement. Pursuant to the terms and conditions set forth in the Merger Agreement, the Company

26

GENTEX CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

acquired all of the issued and outstanding shares of VOXX common stock not already owned by the Company for a purchase price of $7.50 per share, resulting in VOXX becoming a wholly owned subsidiary of Gentex as of the Closing Date. Cash consideration totaling $148.3 million was paid by the Company on the Closing Date, using cash on hand. The acquisition was accounted for under the acquisition method of accounting pursuant to ASC 805, and accordingly, the results of operations and cash flows for VOXX have been included in the Company's Unaudited Condensed Consolidated Financial Statements since the Closing Date.

Prior to obtaining a controlling interest in VOXX, the Company owned 6,463,808 shares of VOXX Class A Common Stock, or approximately 29%, and accounted for this investment using the equity method of accounting, as the Company had the ability to exercise significant influence, but not control, over VOXX. The acquisition transaction was accounted for as a business combination achieved in stages, or a step-acquisition, pursuant to ASC 805 and, as such, the Company was required to remeasure its preexisting equity interest in VOXX immediately prior to the completion of the acquisition to its estimated fair value of $48.5 million using the $7.50 per share acquisition price to determine the fair value of the equity investment. The Company previously recorded changes in fair value of the equity method investment in Investment (loss) income, net, each reporting period, and recorded a gain of $0.8 million during the three months ended March 31, 2025, in the accompanying Unaudited Condensed Consolidated Statements of Income related to VOXX. As a result, the fair value of the investment on the Closing Date was equal to the fair value of the investment on March 31, 2025, the date immediately prior to the acquisition, and no additional gain or loss was recorded on the Closing Date.

VOXX is a leading manufacturer and distributor of automotive OEM and aftermarket electronics, and consumer technologies for the global markets, as well as premium audio solutions through world-renowned brands such as Klipsch®, Onkyo®, and Integra®. The merger also included EyeLock LLC ("EyeLock®"), a majority-owned subsidiary of VOXX, which holds iris biometric technology through its 50% ownership interest in the BioCenturion joint venture. This additional interest in BioCenturion was acquired by the Company in a separate transaction as discussed below. The acquisition of VOXX is a strategic addition to the Company's portfolio of products, as VOXX's product lines will both complement the Company's existing businesses and help the Company continue to expand in the consumer technology and connected home space. The Company has also gained all access to the EyeLock® iris biometric technology, which will provide further product applications in the Gentex automotive, aerospace, and medical markets.

VOXX acquisition is deductible for tax purposes.

Net sales attributable to VOXX in the Company's Unaudited Condensed Consolidated Statement of Income for the three months ended March 31, 2026 were $88.6 million. The net income attributable to VOXX for the three months ended March 31, 2026 was $4.6 million. During the three months ended March 31, 2025, the Company incurred $879,467 in acquisition costs related to the VOXX acquisition, which has been expensed as incurred in the "Selling, general & administrative" section of its Unaudited Condensed Consolidated Statement of Income. No additional acquisition costs were incurred during the three months ended March 31, 2026, related to this acquisition. VOXX's results of operations are included in the Consolidated Financial Statements of the Company within the Automotive, Premium Audio, Aftermarket, Consumer Electronics, and Biometrics operating segments. The Aftermarket, Consumer Electronics, and Biometrics operating segments are presented within the Company's Other reportable segment.

The non-controlling interests included in the net assets acquired in the transaction were comprised of a redeemable non-controlling interest in VOXX's Onkyo subsidiary, and a non-redeemable non-controlling interest in its EyeLock® subsidiary. In conjunction with VOXX's acquisition of Onkyo, a joint venture was formed between VOXX's wholly-owned Premium Audio Company ("PAC") subsidiary and its partner Sharp Corporation ("Sharp"). PAC owns 77.2% of the joint venture and has an 85.1% voting interest and Sharp owns 22.8% of the joint venture and has a 14.9% voting interest. The joint venture agreement between PAC and Sharp contains a put/call option, whereby Sharp has the right to put its interest in the joint venture back to VOXX and VOXX has the right to call Sharp’s ownership interest in the joint venture at any time after the approval of Onkyo’s annual financial statements for the year ending February 28, 2025, at a purchase price based on a formula as defined in the joint venture agreement.

The Onkyo non-controlling interest has been classified as redeemable non-controlling interest outside of equity on the accompanying Unaudited Condensed Consolidated Balance Sheet as the exercise of the put option is not within VOXX’s control. The following table provides the rollforward of the redeemable non-controlling interest for the three months ended March 31, 2026:

	Redeemable Non-controlling Interest
Balance at January 1, 2026	$	3,102,213

Balance at March 31, 2026	3,021,490

As of April 1, 2025, the net assets acquired in the VOXX transaction also included VOXX's non-redeemable non-controlling interest in its EyeLock® subsidiary. On August 18, 2025, the Company acquired the remaining equity interests in EyeLock® from its minority owners for cash consideration totaling $0.1 million.

In November 2024, the Company, in the ordinary course of business, acquired GalvanEyes LLC ("GalvanEyes"), which is the managing partner and 50% owner of the BioCenturion joint venture with Eyelock®. In conjunction with the acquisition of VOXX on April 1, 2025, the Company acquired VOXX's interest in BioCenturion through its majority ownership of Eyelock for cash consideration of $4.1 million.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

RESULTS OF OPERATIONS:

FIRST QUARTER 2026 VERSUS FIRST QUARTER 2025

Net Sales. Consolidated net sales for the first quarter of 2026 increased by $98.7 million or 17%, when compared with the first quarter of 2025, which did not include VOXX. VOXX, one hundred percent of which was acquired on April 1, 2025, contributed $88.6 million of revenue for the first quarter of 2026. Core Gentex revenue (excluding VOXX) was $586.8 million in the first quarter of 2026, representing a 2% quarter over quarter increase, despite global light vehicle production that was down approximately 3% compared to the first quarter of 2025.

Core Gentex Automotive net sales (excluding VOXX) for the first quarter of 2026 were $566.2 million, an increase compared with automotive net sales of $563.9 million in the first quarter of 2025, despite the quarter over quarter decline in global light vehicle production and 6% decrease in total mirror unit shipments in the first quarter of 2026, compared to the first quarter of 2025.

The below table represents the Company's auto-dimming mirror unit shipments for the three months ended March 31, 2026, and 2025 (in thousands):

	Three Months Ended March 31,
	2026	2025	% Change
North American Interior Mirrors	2,272	2,249	1%
North American Exterior Mirrors	1,401	1,370	2%
Total North American Mirror Units	3,673	3,619	1%
International Interior Mirrors	4,509	5,140	(12)%
International Exterior Mirrors	2,671	2,783	(4)%
Total International Mirror Units	7,180	7,923	(9)%
Total Interior Mirrors	6,781	7,389	(8)%
Total Exterior Mirrors	4,072	4,153	(2)%
Total Auto-Dimming Mirror Units	10,853	11,542	(6)%
Note: Percent change and amounts may not total due to rounding.

Core Gentex Other net sales (excluding VOXX) were $20.5 million in the first quarter of 2026, compared to $12.9 million in the first quarter of 2025, an increase of 59%. Other net sales for the first quarter of 2026 included security and access control sales of $3.0 million, an increase of $2.1 million over the first quarter of 2025, primarily generated from the Company's BioConnect subsidiary acquired on July 1, 2025. Dimmable aircraft window sales increased during the first quarter of 2026 to $8.3 million, compared to $4.9 million in the same quarter of last year. Fire protection sales were $8.8 million in the first quarter of 2026, compared to $6.7 million in the same quarter of last year.

Cost of Goods Sold. For the first quarter of 2026, the Company's consolidated gross margin was 33.8% compared to 33.2% in the same quarter last year, which did not include VOXX. The quarter over quarter increase in the gross margin resulted primarily from operational efficiencies and improved product mix, which was partially offset by tariff related costs and commodity price increases. The core Gentex gross margin (excluding VOXX) was 34.0% in the first quarter of 2026, representing an 80 basis-point increase compared to the first quarter of 2025, which did not include VOXX.

Operating Expenses. Consolidated operating expenses were $105.0 million in the first quarter of 2026, compared to $78.7 million in the first quarter of 2025, which did not include VOXX. The increase was primarily due to the VOXX acquisition, which accounted for $23.2 million of the increase. Consolidated operating expenses for the quarter were also impacted by intangible asset impairment charges of $2.8 million related to In-Process R&D previously acquired by the Company. On a non-GAAP basis, core Gentex adjusted operating expenses were $78.3 million in the first quarter of 2026, compared to $75.0 million in the first quarter of 2025, when excluding the impact of intangible asset impairment charges, acquisition related costs, and severance costs in each of the quarters, for comparability.

30

Engineering, research and development expenses for the first quarter of 2026 increased by $5.7 million, when compared with the first quarter of 2025, primarily due to the VOXX acquisition, as well as staffing and engineering related professional fees.

Selling, general and administrative ("S, G & A") expenses increased by $19.9 million for the first quarter of 2026, compared to the first quarter of 2025, primarily due to the VOXX acquisition. S, G & A expenses were approximately 7% of net sales in the first quarter of 2026, compared to 5% in the first quarter of 2025, which did not include VOXX.

Other (Loss) Income, Net. Total Other loss, net for the first quarter of 2026 was $5.6 million, when compared with total Other income, net, of $0.6 million for the first quarter of 2025. The quarter over quarter decline was driven by lower investment income, as well as an impairment charge of $2.7 million related to one of the Company's technology investments and an increase in credit loss reserves related to loans receivable of $2.2 million during the first quarter of 2026.

Provision for Income Taxes. The effective tax rate was 16.6% for, and an income tax expense of $19.6 million was recorded in, the first quarter of 2026, compared to an effective tax rate of 16.5% for, and an income tax expense of $18.8 million recorded in, the same quarter of 2025. Generally, effective tax rates for the Company differ from statutory federal income tax rates due to provisions for state and local income taxes, the FDDEI deduction, and research and development tax credits.

Net Income Attributable to Gentex Corporation. Consolidated net income attributable to Gentex for the first quarter of 2026 was $98.5 million, an increase of 4% compared to net income attributable to Gentex of $94.9 million in the first quarter of 2025, which did not include VOXX. The quarter over quarter increase in net income for the first quarter of 2026 was due to higher sales and income from operations compared to the same quarter last year. Non-GAAP consolidated net income attributable to Gentex was $103.7 million in the first quarter of 2026, compared to $98.0 million in the first quarter of 2025 (which did not include VOXX), when adjusting for the impact of impairment charges, acquisition related costs, and severance costs in each of the quarters, for comparability.

Earnings Per Share Attributable to Gentex Corporation. The Company had consolidated earnings per diluted share attributable to Gentex for the first quarter of 2026 of $0.46, which compared to earnings per diluted share of $0.42 for the first quarter of 2025, which did not include VOXX. Earnings per diluted share were also positively impacted by the increase in sales and improved profitability of the Company, partially offset by other losses incurred in the first quarter of 2026. On a non-GAAP basis, consolidated adjusted earnings per diluted share attributable to Gentex were $0.48 for the first quarter of 2026, compared to $0.43 for the first quarter of 2025 (which did not include VOXX), excluding the impact of impairment charges, acquisition related costs, and severance costs in each of the quarters, for comparability.

The Company has not recognized any potential refund of IEEPA tariffs in its first quarter financial results. The Company remains in the process of assessing the impact of the invalidation of IEEPA tariffs by the U.S. Supreme Court. As of March 31, 2026, the Company estimates that approximately $15 million of IEEPA tariff costs have been capitalized in inventory, which have not yet been expensed as of that date. Since the inception of the IEEPA tariffs, the Company (including VOXX) has directly paid a cumulative total of approximately $42 million (excluding amounts paid indirectly through suppliers), partially offset by approximately $5 million of costs recovered from customers. While the Company is pursuing refunds as it determines appropriate, the availability, amount, and timing of any potential refunds remains highly uncertain and subject to further legal, regulatory, and administrative developments. As such, the Company is unable to conclude any recovery is probable and reasonably estimable as of March 26, 2026.

NON-GAAP FINANCIAL MEASURES:

Financial information for the three months ended March 31, 2026 is provided in accordance with Generally Accepted Accounting Principles ("GAAP"). In addition, the Company believes that it is useful for the three months ended March 31, 2026 to provide certain non-GAAP measures, including Adjusted Operating Expenses, Adjusted Income from Operations, Adjusted Other (Loss) Income, Adjusted Net Income Attributable to Gentex Corporation, and Adjusted Earnings per Share, with the adjustments set forth in the "Reconciliation of Non-GAAP Measures" table below. This non-GAAP financial information allows investors to evaluate current performance in the Company's core business in relation to historical performance by excluding the impact of certain impairment charges, acquisition related costs, and severance costs set forth in the table below.

The Company believes that the presentation of these non-GAAP financial measures provides insight into the Company's core performance and trends with respect to the same. Management of the Company similarly uses such non-GAAP financial measures in assessing the business internally. A reconciliation of Adjusted Operating Expenses, Adjusted Income from Operations, Adjusted Other (Loss) Income, Adjusted Net Income Attributable to Gentex Corporation, and Adjusted Earnings per Share to the most directly comparable GAAP measures is provided in the "Reconciliation of non-GAAP Measures" tables below. Like all non-GAAP financial measures, these non-GAAP measures are intended to supplement, not to replace, GAAP measures.

FINANCIAL CONDITION:

The Company's cash and cash equivalents as of March 31, 2026 were $164.8 million, an increase of $19.1 million, compared to $145.6 million as of December 31, 2025. The increase was primarily due to cash flows from operations, including increases in accounts payable and accrued liabilities, offset by cash outflows related to share repurchases, dividend payments, capital expenditures, and investment purchases during the three months ended March 31, 2026.

Short-term investments as of March 31, 2026 were $10.3 million, an increase from $5.4 million as of December 31, 2025, and long-term investments were $270.1 million as of March 31, 2026, down from $273.0 million as of December 31, 2025.

Accounts receivable as of March 31, 2026 increased approximately $51.0 million compared to December 31, 2025, primarily due to the timing of customer payments during the three months ended March 31, 2026.

Inventories as of March 31, 2026 were $523.5 million, compared to $516.3 million as of December 31, 2025, primarily due to an increase in work-in-process inventory at March 31, 2026.

Accounts payable as of March 31, 2026 increased approximately $27.7 million to $276.6 million, compared to December 31, 2025, primarily driven by timing of payments within the period.

Accrued liabilities as of March 31, 2026 increased approximately $29.3 million compared to December 31, 2025, primarily due to an increase in income taxes payable.

Cash flow from operating activities for the three months ended March 31, 2026 decreased $11.4 million to $137.1 million, compared with $148.5 million during the same period last year, primarily due to changes in working capital.

Capital expenditures for the three months ended March 31, 2026 were approximately $17.0 million, compared with approximately $36.7 million for the same period last year. The decrease was primarily due to the timing of completion and commencement of projects, including the completion of the Gentex Discovery Preschool in 2025, as further described below.

The Company believes its existing and planned facilities are currently suitable, adequate, and have the capacity required for current and near-term planned business. Nevertheless, the Company continues to evaluate longer term facility needs.

During the fourth quarter of 2025, the Company completed construction of the previously announced Gentex Discovery Preschool, an on-site daycare and preschool designed to provide Company employees with convenient, cost-effective access to quality childcare. The total cost of the building project was approximately $20 million and was funded with cash on hand.

The Company estimates that it currently has building capacity to manufacture approximately 42 - 45 million interior automatic-dimming mirror units annually, and approximately 19 - 22 million exterior mirror units annually, based on current product mix. The Company also evaluates equipment capacity on an ongoing basis and adds equipment as needed.

Management considers the current working capital and long-term investments, in addition to internally generated cash flow, its Credit Agreement, and credit worthiness, to be sufficient to cover anticipated cash needs for the foreseeable future considering its contractual obligations and commitments.

The following is a summary of working capital and long-term investments:

	March 31, 2026		December 31, 2025
Working Capital	$	763,613,741	$	740,891,499
Fixed Income Long-Term Investments	103,369,919		108,145,410
Total	$	866,983,660	$	849,036,909

The Company has a previously announced share repurchase plan under which the Board of Directors has authorized the repurchase of shares of the Company's common stock, which remains a part of the broader publicly disclosed capital allocation strategy. Future share repurchases may vary from time to time and will take into account macroeconomic events, market trends, and other factors the Company deems appropriate (including, but not limited to, the market price of the stock, anti-dilutive effect of repurchases, and available cash). During the three months ended March 31, 2026, the Company repurchased 3,252,696 shares. The Company had 32,747,032 shares remaining available for repurchase under the plan as of March 31, 2026, as is further detailed in Part II, Item 2 of this Form 10-Q.

BUSINESS UPDATE

For the first quarter of 2026, the Company reported net sales of $675.4 million, compared to net sales of $576.8 million in the first quarter of 2025 (which did not include VOXX), a 17% increase quarter over quarter. Core Gentex revenue (excluding VOXX) for the first quarter of 2026 increased 2% versus the first quarter of 2025, despite a global decline in light vehicle production of approximately 3% in the first quarter of 2026, compared to the first quarter of 2025.

During the three months ended March 31, 2026, over 65% of the Company's mirror launches were interior and exterior auto-dimming mirrors with advanced electronic features, with HomeLink® and Full Display Mirror®, ("FDM") as the primary drivers of growth.

PRODUCT UPDATE

Mirror Systems

In 2024, the United Nations Economic Commission (UN ECE) established a working group (Task Force Glare Protection) on the subject of glare in road traffic. The Task Force Glare Protection will investigate the burden and danger of road glare from vehicle headlamps and initiate necessary measures. The Company believes its auto-dimming mirror products can be a solution for necessary measures initiated by this UN ECE task force.

Camera Systems

The Company's FDM began production in 2015. Current automotive design trends are yielding vehicles with small rear windows that are often further obstructed by headrests, passengers, and roof support pillars, which can significantly hinder the mirror’s rearward view. The Company's FDM is an intelligent rear vision system that uses a custom, internally or externally mounted video camera and mirror-integrated video display to optimize a vehicle driver’s rearward view. This rear vision system consists of a hybrid FDM that offers bi-modal functionality. In mirror mode, the product functions as an auto-dimming rearview mirror which means that during nighttime driving, digital light sensors talk to one another via a microprocessor to automatically darken the mirror when glare is detected. With the flip of a switch, the mirror enters display mode, and a clear, bright display appears through the mirror’s reflective surface, providing a wide, unobstructed rearward view. The bi-modality of the FDM is essential, because in the event of any failure of the camera or display, the product is able to function as a mirror, which meets long-standing safety requirements in the automotive industry. In addition, the driver has the ability to switch between modes to accommodate usage preferences for various weather conditions, lighting conditions, and driving tasks. FDM remained a leading performer for the Company for the first quarter of 2026.

To enhance capability and usability of the FDM, the Company previously introduced its three-camera rear vision system that streams rear video in multiple composite views to its FDM. The Company believes it is the industry’s first practical and comprehensive rear vision solution designed to meet automaker, driver, safety, and regulatory requirements. The Company's rear vision system, known generally as a camera monitoring system ("CMS"), uses three cameras to provide a comprehensive view of the sides and rear of the vehicle. The side-view cameras are discretely housed in downsized, automatic-dimming exterior mirrors. Their video feeds are combined with that of a roof-mounted or rear window-based camera and stitched together into multiple composite views, which are streamed to the driver using the FDM. During any failures due to weather conditions or otherwise that disrupt the digital view, drivers can still safely use the interior and exterior mirrors. The system also supports user preference by permitting drivers to use standard mirror views, camera views, or both. The system can also be tuned to meet the various regulatory field-of-view requirements around the world by using different types of flat and curved glass, combined with simple alterations to the video viewing modes. Downsized exterior mirrors provide automakers with significant weight savings and fuel efficiency improvements. To further enhance safety, the Company's CMS solution can also work in conjunction with a vehicle’s side blind zone warning system. When a trailing vehicle enters a side blind zone, a warning indicator illuminates in both the interior and exterior mirrors, while the corresponding side-view video feed appears in the display until the vehicle passes. CMS solutions also helped drive revenue growth in the first quarter of 2026, compared to the first quarter of 2025, with CMS product shipping to Rivian, Volvo, and Polestar. The Company expects to begin shipping CMS products to additional OEM customers in the second and third quarters of 2026.

The Company began shipping FDM with Digital Video Recording ("DVR") capability in 2020. This mirror and system launched in the Japan market and combines the superior functionality of the FDM with the added capability to record video from the rearward facing and forward-facing cameras simultaneously. In 2025, the Company introduced its next-generation FDM, which incorporates the Company’s Dynamic View Assist, a series of dynamic viewing modes that can enhance driving safety and make using a digital mirror feel more natural. By utilizing a higher resolution imager, the FDM can automatically expand the mirror’s digital view, digitally tilt downward, while reversing, and can display picture in picture functions.

In July 2016, a revision to UN-ECE Regulation 46 was published with an effective date of June 18, 2016, which allows for camera monitoring systems to replace mirrors in Japan and European countries. Since January 2017, camera monitoring systems are also permitted as an alternative to replace mirrors in the Korea market. China released an updated version of its GB15084, effective in 2023, which allows for camera monitoring systems, frameless mirrors and

35

aspheric (free form) glass surfaces. Notwithstanding the foregoing, the Company continues to believe rearview mirrors provide a robust, simple and cost-effective means to view the surrounding areas of a vehicle and remain a primary safety function for rear vision today. Cameras, when used as the primary rear vision delivery mechanism, have some inherent limitations, such as: electrical failure; cameras being blocked or obstructed; depth perception challenges; and viewing angles of the camera. Nonetheless, the Company continues designing and manufacturing not only rearview mirrors, but CMOS imagers and video displays as well. The Company believes that combining video displays with mirrors may well provide a more robust product by addressing all driving conditions in a single solution that can be controlled by the driver. The Company has also previously announced that it continues development in the areas of imager performance, camera dynamic range, lens design, image processing from the camera to the display, and camera lens cleaning. The Company acknowledges that as such technology evolves over time, such as cameras replacing mirrors and/or autonomous driving, there is increased competition.

Connected Car

The Company's HomeLink® products are the auto industry's most widely used and trusted car-to-home communication system. The system consists of two or three in-vehicle buttons that can be programmed to operate garage doors, security gates, home lighting, and other radio-frequency-controlled devices. In 2017, the Company demonstrated the next generation of HomeLink®, commonly referred to as HomeLink Connect®, a smartphone app that uses both RF and wireless cloud-based connectivity to deliver complete vehicle-to-home automation. With HomeLink Connect®, a HomeLink® button press communicates with the HomeLink Connect® app on the user’s smartphone. The app contains predefined, user-programmed actions, from single device operations to entire home automation scenes. The app, in turn, communicates to the home’s smart hub over the cloud, activating the appropriate devices, including security systems, door locks, thermostats, lighting, and other home automation devices, providing comprehensive vehicle-to-home automation. The ability to prepare the home for arrival or departure can occur with one button press. For automakers, this functionality allows them to offer customizable, yet proven solutions without the engineering efforts or security concerns associated with integrating third party software into the vehicle’s computer network. In 2021, the Company announced Volkswagen as the first automaker to offer Bluetooth® enabled mirror for home automation that works in conjunction with HomeLink Connect®.

In 2016, the Company announced a partnership with TransCore to provide automobile manufacturers with a vehicle-integrated tolling solution that enables motorists to drive on nearly all U.S. toll roads without a traditional toll tag on the windshield. The interior mirror is the optimal location for a vehicle-integrated toll transponder, and it eliminates the need to affix multiple toll tags to the windshield and helps automakers seamlessly integrate toll collection into the car. The Company's Integrated Toll Module® or ITM® simplifies and expedites local, regional, and national travel and provides transportation agencies with an interoperability solution without costly infrastructure changes to the thousands of miles of toll lanes throughout North America. Currently, the Company is shipping ITM® on 11 Audi platforms, as well as on the Mercedes EQS model. In 2020, the Company was honored with an Automotive News PACE Award for its ITM® product, which recognizes automotive suppliers for superior innovation, technological advancement, and business performance.

Further, the Company previously announced an embedded biometric solution for vehicles that leverages iris scanning technology to create a secure environment in the vehicle. There are many use cases for authentication, which range from vehicle security to start functionality to personalization of mirrors, music, seat location, and temperature, to the ability to control transactions not only for the ITM® system, but also the ride sharing car of the future. The Company believes iris recognition is among the most secure forms of biometric identification, with a false acceptance rate as low as one in 10 million, far superior to facial, voice, and other current biometric systems. The Company's future plans include integrating biometric authentication with many of its other electronic features, including HomeLink® and HomeLink Connect®. The biometric system will allow HomeLink® to provide added security and convenience for multiple drivers by activating the unique home automation presets of different authorized users.

Dimmable Aircraft Windows

The Company continues to manufacture and sell variable dimmable windows for the passenger compartment on the Boeing 787 Dreamliner series of aircraft. The Company continues to work with other aircraft manufacturers that have an interest in this technology regarding potential additional programs. The Company also previously announced that its latest generation of dimmable aircraft windows would be offered as optional content on the Boeing 777X aircraft. In 2019, the first production shipments of variably dimmable windows were made to Boeing for the 777X program. As also previously announced, Airbus is now offering, as optional content, the Company's dimmable aircraft windows on its aircraft, with production having begun in 2021.

Medical

In 2020, the Company unveiled an innovative lighting technology for medical applications that was co-developed with Mayo Clinic. This new lighting concept represents the collaboration of a global, high-technology electronics company with a world leader in health care. The Company's new intelligent lighting system combines ambient room lighting with camera-controlled, adaptive task lighting to optimize illumination for surgical and patient-care environments. The

36

Company continues to further develop and work on the intelligent medical lighting system in order to assess system performance and work toward obtaining any necessary approvals.

In November 2023, in the ordinary course of business, the Company acquired certain technology assets from eSight. The technology acquired provides the most advanced and versatile low-vision smart glasses available for those with visual impairments and is compatible with more than 20 eye conditions including Macular Degeneration, Diabetic Retinopathy, and Stargardt disease.

Biometric Products

In 2024, the Company acquired GalvanEyes, LLC, which is the managing partner and 50% owner of the BioCenturion joint venture with Eyelock, a majority-owned subsidiary of VOXX. BioCenturion specializes in creating and deploying authentication solutions to help clients secure their worlds, optimize their workloads, and organize their data through customized biometric solutions. BioCenturion's significant IP portfolio, including more than 100 patents granted, patents pending, and proprietary technology enables a high-speed, convenient, touchless, contactless, frictionless, and secure authentication of individuals across different business verticals. With the acquisition of VOXX on April 1, 2025, which included its majority-owned subsidiary EyeLock®, and the subsequent acquisition of the remaining interest in EyeLock® in August 2025, the Company now owns 100% of BioCenturion. These acquisitions have also enabled the Company to gain full access to the EyeLock® iris biometric technology, which will provide more product applications in the Company's automotive, aerospace, and medical markets. In July 2025, the Company acquired BioConnect, a multi-modal biometric authentication platform provider for physical and digital access control, serving a number of industries. The Company intends to utilize this acquisition to further expand its reach in the biometric space.

Fire Protection

During 2025, the Company began shipments of its PLACE product line. PLACE is a suite of advanced, multi-functional smoke and carbon monoxide alarms designed to elevate home safety, comfort, and security through room-specific intelligence. The system is managed via an intuitive mobile app and features an industry-first low-frequency sounder, engineered to improve alarm effectiveness for deep sleepers, children, and individuals with hearing impairments. It also aligns with emerging safety standards, including updated residential codes adopted in states like California.

Premium Audio Products

With the acquisition of VOXX on April 1, 2025, the Company made strategic additions to its portfolio of products, as VOXX's product lines both complement the Company's existing businesses and will help the Company continue to expand in the consumer technology and connected home space. During the first quarter of 2026, the teams at Klipsch, Onkyo, and Integra launched premium audio products that were showcased at CES in January of 2026, including the The Fives®, The Sevens®, and The Nines® powered speaker products.

OTHER

Automotive revenues represented approximately 86% of the Company's total revenue during the three months ended March 31, 2026, consisting of interior and exterior electrochromic automatic-dimming rearview mirrors and other automotive electronics.

The Company has been, is being, and will continue to be impacted by tariffs, trade regulatory actions, and changes in international trade policies as further explained below.

The Company continues to experience pricing pressure from automotive customers and competitors, in addition to tariff increases, raw material cost increases, labor cost increases, and logistics cost increases, which will continue to cause downward pressure on its sales and profit margins. The Company works continuously to offset these tariff costs, supply chain issues, and inflationary pressures with engineering and purchasing cost reductions, productivity improvements, increases in unit sales volume, and negotiations with customers to reduce the impact of the same, but there is no assurance the Company will be successful in doing so in the future.

Because the Company sells its products throughout the world, and automotive manufacturing is highly dependent on economic conditions, the Company is affected by uncertain economic conditions that reduce demand for its products, including the current inflationary environment and tariffs. The Company is likewise affected by industry-wide parts shortages and global supply constraints and labor shortages.

The Company believes that its patents and trade secrets provide it with a competitive advantage in dimmable devices, electronics, and other features that it offers for the automotive, premium audio, fire protection, aerospace, medical, consumer electronics, and access and control, and biometrics industries. Claims of patent infringement, however, can be costly and time-consuming to address. To that end, the Company obtains intellectual property rights in the ordinary course of business to strengthen its intellectual property portfolio and to minimize the risk of infringement.

The Company does not have any significant off-balance sheet arrangements or commitments that have not been recorded in its Unaudited Condensed Consolidated Financial Statements.

OUTLOOK

The Company’s light vehicle production forecast for the second quarter of 2026 and full years 2026 and 2027 are based on the mid-April 2026 S&P Global Mobility outlook for North America, Europe, Japan/Korea, and China (see table below). Based on the S&P Global mobility forecast, global light vehicle production for the second quarter of 2026 is expected to decline 2% versus the second quarter of 2025, while light vehicle production in the Company's primary markets is expected to be down over 3% quarter over quarter. Full-year 2026 production in the Company's primary markets is also expected to decline 2% year over year based on the S&P Global mobility forecast. Forecasted light vehicle production volumes from S&P Global Mobility for the second quarter of 2026 and calendar years 2026 and 2027 are shown below:

Light Vehicle Production (per S&P Global Mobility mid-April light vehicle production forecast)
(in Millions)
Region	Q2 2026	Q2 2025	% Change		Calendar Year 2027	Calendar Year 2026	Calendar Year 2025	2027 vs 2026 % Change		2026 vs 2025 % Change
North America	3.81	3.95	(4)	%	15.30	14.96	15.27	2	%	(2)	%
Europe	4.31	4.47	(4)	%	16.87	16.75	17.05	1	%	(2)	%
Japan and Korea	2.95	3.02	(2)	%	11.57	11.82	12.07	(2)	%	(2)	%
China	7.73	7.76	—	%	32.46	32.34	33.10	—	%	(2)	%
Total Light Vehicle Production	18.80	19.20	(2)	%	76.20	75.87	77.49	—	%	(2)	%

Based on the updated light vehicle production forecast and actual results for the first three months of 2026, as well as the Company’s estimates for premium audio, aerospace, medical, fire protection, and consumer electronic products, the Company has made certain changes to its full-year 2026 guidance. This most recent guidance reflects the anticipated impact of all known tariffs effective as of April 24, 2026.

2026 Annual Guidance (as of April 24, 2026)

•Consolidated Revenue: $2.65 – $2.75 billion (previously: $2.60 – $2.70 billion)

•Gross Margin: 34% – 35% (no change)

•Operating Expenses (excluding severance and impairments): $410 – $420 million (no change)

•Tax Rate: 16% – 18% (no change)

•Capital Expenditures: $125 – $140 million (no change)

•Depreciation & Amortization: $100 – $110 million (no change)

Based on the mid‑April 2026 S&P Global Mobility light‑vehicle production outlook and the Company’s estimates for premium audio, aerospace, medical, fire protection, and consumer electronics products, the Company continues to expect calendar‑year 2027 revenue to range between $2.80 billion and $2.90 billion.

Ongoing uncertainties remain, including: prolonged and intensifying trade wars, including the impacts of tariffs already in place, and potential additional future tariffs, trade restrictions, and retaliatory measures; the war in Iran; the Ukraine-Russia war; the Israel-Hamas war; light vehicle production levels; impacts of regulation changes; automotive plant shutdowns; vehicle sales rates, especially in Europe, Asia and North America; OEM strategies and cost pressures; supply chain constraints: customer inventory management and the impact of potential automotive customer (including their Tier 1 suppliers) and supplier bankruptcies; etc., all of which are disrupting and will further disrupt shipments to customers, disrupt global capital flows, and heighten market volatility.

In accordance with the previously announced share repurchase plan, the Company will consider the appropriateness of continuing to repurchase additional shares of common stock in the future in support of the capital allocation strategy, but share repurchases will vary from time to time and will take into account macroeconomic events, market trends, and other factors the Company deems appropriate (including the market price of the stock, anti-dilutive effect of repurchases, and available cash). As of March 31, 2026, the Company had 32.7 million shares remaining available for repurchase under the previously announced share repurchase plan.

CRITICAL ACCOUNTING POLICIES:

The preparation of the Company’s consolidated condensed financial statements contained in this report, which have been prepared in accordance with accounting principles generally accepted in the United States, requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, management evaluates these estimates. Estimates are based on historical experience and/or on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that may not be readily apparent from other sources. Historically, actual results have not been materially different from the Company’s estimates. However, actual results may differ from these estimates under different assumptions or conditions.

The Company has identified critical accounting policies used in determining estimates and assumptions in the amounts reported in its Management’s Discussion and Analysis of Financial Condition and Results of Operations herein and in its Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Item 3.    Quantitative And Qualitative Disclosures About Market Risk.

The Company is subject to market risk exposures of varying correlations and volatilities, changes in interest rates, commodity price risk, and foreign currency exchange rates. For the quarter ended March 31, 2026, any material changes in risk factors that were disclosed in the Company's report on Form 10-K for the year ended December 31, 2025 are set forth herein.

Interest Rate Risk

Fluctuating interest rates and securities prices could negatively impact the Company's financial performance as a result of realized losses on the sale of fixed income investments and/or realized losses due to an impairment adjustment on investment securities. The Company is exposed to interest rate risk primarily through its available-for-sale security portfolio, which consists mainly of investment-grade debt securities. Changes in interest rates may affect the fair value of these investments. Though the Company does have a short-term borrowing, such debt bears interest at a fixed rate. As such, changes in market interest rates will not materially affect any such interest expense. The Company did not have an outstanding balance related to its revolving credit facility at March 31, 2026, or December 31, 2025. Management does not believe that interest rate risk at the current time has a material impact on the Company’s financial condition, results of operations, or cash flows.

Commodity Price Risk

In the ordinary course of business, the Company has exposure to commodity price fluctuations related to the purchases of certain materials used in its manufacturing operations. Such materials used in manufacturing operations are increasing in price based on competitive market conditions. To the extent that the Company has established pricing terms with customers through contracts or similar arrangements, the ability to increase prices of its products to offset the increased costs of materials is limited. The Company does not currently enter into derivative financial instruments associated with commodities.

Foreign Currency Exchange Rates

A portion of the Company's operations consist of activities outside of the U.S. As a result, the Company has currency risk on the transactions in other currencies and translation adjustments resulting from the conversion of international financial results into the U.S. dollar. A substantial majority of the Company's operations and investment activities are transacted in the U.S. and in U.S. dollars. Less than 10% of Company revenues for the three months ended March 31, 2026, and 2025, were earned in non-U.S. dollar denominated currencies. As of March 31, 2026, the Company has no outstanding foreign currency forward contracts entered into to manage exposure to U.S. dollar-denominated transactions for risk management purposes. Management does not believe that foreign currency exchange rate risk, including the use of such forward contracts, currently has a material impact on the Company’s financial condition, results of operations, or cash flows.

The Company does not have any significant off-balance sheet arrangements or commitments that have not been recorded in its Unaudited Condensed Consolidated Financial Statements.

Item 4.    Controls And Procedures.

Evaluation of Disclosure Controls and Procedures.

Under the supervision of, and with the participation of management, the Company's Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of March 31, 2026, and have concluded that as of that date, the Company's disclosure controls and procedures are effective.

39

Changes in Internal Control Over Financial Reporting

There were no changes in the Company's internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the quarter ended March 31, 2026 that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(c)    Issuer Purchase of Equity Securities

The Company has a previously announced share repurchase plan under which the Board of Directors has authorized the repurchase of shares of the Company's common stock, which remains a part of the broader publicly disclosed capital allocation strategy. During the first three months of 2026, the Company repurchased 3.3 million shares under the share repurchase plan. As previously disclosed, the Company will consider the appropriateness of continuing to repurchase additional shares of common stock in the future in support of the capital allocation strategy, but share repurchases will vary from time to time and will take into account macroeconomic events, market trends, and other factors the Company deems appropriate (including the market price of the stock, anti-dilutive effect of repurchases, and available cash).

After the Company repurchased 3,252,696 shares during the first three months of 2026, the Company had 32,747,032 shares remaining under the plan as of March 31, 2026.

The following is a summary of share repurchase activity during each month of the three-month period ended March 31, 2026:

Adoption of New Accounting Standards

3 Months Ended

Mar. 31, 2026

Accounting Policies [Abstract]

Adoption of New Accounting Standards

Adoption of New Accounting Standards

In March 2024, the Securities and Exchange Commission ("SEC") issued Final Rule No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors." If such rule becomes effective, the rule will require disclosure of climate-related information outside of the audited financial statements and disclosure in the footnotes to such financial statements addressing specified financial statement effects of severe weather events and other natural conditions above certain financial thresholds, certain carbon offsets and renewable energy credits or certificates, if material. Such disclosure requirements were scheduled to begin phasing in for fiscal years beginning on or after January 1, 2025. On April 4, 2024, the SEC exercised its discretion to voluntarily stay the effective date of the final rules pending completion of certain judicial review. In 2025, the SEC withdrew its defense of the climate disclosure rules and litigation has been held in abeyance. The SEC has launched a formal review, inviting public comment, with an eye toward facilitating disclosure of consistent, comparable, and reliable information on climate change. Though compliance with such rules is not currently required, and it is unclear when or if compliance will be required, the Company continues to evaluate the potential impact of compliance, as well as compliance with similar rules of other jurisdictions.

In November 2024, the FASB issued ASU No. 2024-03, "Disaggregation of Income Statement Expenses (Subtopic 220-40)." The ASU requires public business entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Companies have the option to apply the guidance either on a retrospective or prospective basis, and early adoption is permitted. In January 2025, the FASB issued ASU No. 2025-01, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date." This ASU amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of adopting these ASU's on the Consolidated Financial Statements and related disclosures.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity ("VIE"), which provides clarifying guidance on determining the accounting acquirer in certain transactions involving VIE's. The update aims to improve consistency and comparability in financial reporting. The guidance will be effective for annual periods beginning after December 15, 2026, including interim periods within those annual periods. Early adoption is permitted. Upon adoption, the guidance will be applied prospectively. The Company is currently evaluating the provisions of the guidance and the impact on its future Consolidated Financial Statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which introduces a practical expedient for the application of the current expected credit loss model to current accounts receivable and contract assets in which all entities can assume that current conditions as of the balance sheet date do not change for the remaining life of the assets. This ASU was effective for the Company in the first quarter of 2026 and did not have a material impact the Company's Consolidated Financial Statements and disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU updates the cost capitalization threshold for internal-use software development costs by removing all references to software project development stages and providing new guidance on how to evaluate whether the probable-to-complete recognition threshold has

been met. ASU 2025-06, which can be applied prospectively, retrospectively, or with a modified transition approach, is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and disclosures.

In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging - Hedge Accounting Improvements (Topic 815), which amends certain aspects of the hedge accounting guidance to better align financial reporting with the economics of an entity's risk management activities. ASU 2025-09 is effective for annual and interim periods beginning after December 15, 2026. Early adoption is permitted and is effective on a prospective basis. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements ("ASU 2025-11"). This ASU enhances consistency in interim reporting for all entities by clarifying interim disclosure requirements and the form and content of interim financial statements in accordance with GAAP. ASU 2025-11, which can be applied prospectively or retrospectively to any and all prior periods presented in the financial statements, is effective for the interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and related disclosures.

(1) The gross carrying values of goodwill in the Automotive Products and Premium Audio Products segments are equal to their net carrying values as there have been no impairments of goodwill within these segments.

In addition to annual impairment testing, which is performed as of the first day of the Company's fourth quarter, the Company continuously monitors for events and circumstances that could negatively impact the key assumptions in determining fair value of goodwill or other intangible assets, thus resulting in the need for interim impairment testing, including: long-term revenue growth projections; profitability; discount rates; recent market valuations from transactions by comparable companies; volatility in the Company's market capitalization; and general industry, market, and macroeconomic conditions.

During the first quarter of 2026, as a result of costs to develop the Company's In-Process Research and Development ("In Process R&D") continuing to exceed original estimates, as well as delays in the expected timing of commercialization of the related technology, management approved and began executing a plan to cease operations at the facility where its Vaporsens In-Process R&D activities were conducted. This plan included the termination of substantially all employees associated with those activities. As a result, the Company discontinued further development of the underlying technology and shifted its strategy to the potential sale of the related assets. These actions represented a significant adverse change in the extent and manner in which the In-Process R&D was expected to be used and in its projected future cash flows, indicating that the carrying value of the asset may not be recoverable. Accordingly, the Company recorded an impairment charge of $2.8 million during the three months ended March 31, 2026, to reduce the carrying amount of the asset to its estimated fair value. The estimated fair value was determined based on the Company's estimate of the expected selling price of the asset, taking into consideration available market information and indicative third-party interest, as applicable.

Except as set forth, the Company noted no other events or circumstances indicating the need for interim impairment testing of its goodwill or other intangible assets during the first quarter of 2026.

The Company's patents and intangible assets and related change in carrying values are set forth in the tables below, including the Vaporsens In-Process R & D, which has been previously disclosed.

Investments

Investments

Available for sale securities

The Company follows the provisions of Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures, for its financial assets and liabilities, and for its non-financial assets and liabilities subject to fair value measurements. ASC 820 provides a framework for measuring the fair value of assets and liabilities. This framework is intended to provide increased consistency in how fair value determinations are made under various existing accounting standards that permit, or in some cases, require estimates of fair-market value. This standard also expanded financial statement disclosure requirements with respect to a company’s use of fair-value measurements, including the effect of such measurements on earnings. The cost of securities sold is based on the specific identification method.

The Company determines the fair value of its asset-backed securities, municipal bonds, and corporate bonds by utilizing monthly valuation statements that are provided by its broker. The broker determines the investment valuation by utilizing the bid price in the market and also refers to third party sources to validate valuations, and as such are classified as Level 2 assets.

The Company's certificates of deposit are classified as available for sale and are considered as Level 1 assets. These investments are carried at cost, which approximates fair value.

Equity Method Investment - ASA

The Company has a 50% non-controlling ownership interest in ASA Electronics, LLC and Subsidiary ("ASA"), that was obtained in conjunction with the acquisition of VOXX International Corporation ("VOXX") on April 1, 2025 (see Note 16) and is accounted for in accordance with ASC 323, Investments – Equity Method and Joint Venture. ASA acts as a distributor of mobile electronics, specifically designed for niche markets, including: RV's; buses; and commercial, heavy duty, agricultural, construction, powersport, and marine vehicles. ASC 810, Consolidation, requires the Company to evaluate non-consolidated entities periodically, and as circumstances change, to determine if an implied controlling interest exists. The balance of the Company's investment in ASA was $20.5 million and $20.0 million as of March 31, 2026 and December 31, 2025, respectively, and included in Long-term investments on the accompanying Unaudited Condensed Consolidated Balance Sheets.

Technology Investments

The Company also periodically makes strategic investments in the non-marketable debt or equity securities of other non-consolidated third parties ("Technology Investments"). Such Technology Investments totaled $146.2 million as of March 31, 2026, and are recorded in long-term investments on the accompanying Unaudited Condensed Consolidated Balance Sheet. Such Technology Investments totaled approximately $146.6 million as of December 31, 2025, of which $144.9 million and $1.7 million are included in long-term investments and short-term investments, respectively, on the accompanying Unaudited Condensed Consolidated Balance Sheets. Depending on the form of investment, and the degree of influence the Company has over the investee, the Company primarily accounts for the Technology Investments in accordance with ASC 321, Investments - Equity Securities or ASC 323, Investments – Equity Method and Joint Venture. The Company accounts for equity securities in non-controlled affiliates through which the Company exercises significant influence but does not have control over the investee under the equity method, with the Company’s share of the earnings or losses of non-controlled affiliates recognized within Other (loss) income, net, in the Company's accompanying Unaudited Condensed Consolidated Statements of Income. All other Technology Investments that the Company holds are primarily accounted for under the measurement alternative of ASC 321. Under the measurement alternative, the carrying value is measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer.

During the three months ended March 31, 2026, the Company recognized a loss of $1.7 million within Other, net, related to warrants held in one of the Company's technology investments that expired unexercised during the quarter.

During the same period, the Company recorded an other-than-temporary impairment charge of $2.7 million related to one of its technology investments, which is included in Investment (loss) income, net, on the accompanying Unaudited Condensed Consolidated Statement of Income. During the first quarter of 2026, the Company identified indicators of impairment related the investment, including a sustained deterioration in the entity's operating results and financial condition, as well as the execution of a forbearance agreement associated with outstanding loans from the Company to the investee totaling approximately $5.0 million (exclusive of credit reserves) as of March 31, 2026. Based on these factors, the Company determined that the decline in fair value of its investment was other-than-temporary. The Company concluded that the estimated fair value of its equity interest was negligible, as the investee's enterprise value was not expected to be sufficient to satisfy the Company's outstanding loan exposure. Accordingly, the Company recorded a full impairment charge to reduce the carrying amount of the investment to zero.

From time to time, the Company makes loans in the ordinary course of business to certain of its technology investees. Such loans vary in length and are interest bearing, and as such are not deemed to be additional investments in the technology investees as the parties intend for the loans to be repaid. These loans are classified within Prepaid expenses and other and Patents and other assets, net, on the accompanying Unaudited Condensed Consolidated Balance Sheets based on the maturity dates of the loans. The Company estimates an allowance for credit losses for these loans receivable in accordance with ASC 326, Financial Instruments - Credit Losses. This allowance reflects the Company's estimate of expected credit losses over the contractual life of the loans, considering historical loss experience, current conditions, and reasonable and supportable forecasts. The estimate is developed using a combination of quantitative data and qualitative factors, including borrower creditworthiness, loan-specific risk characteristics, macroeconomic trends, and other relevant information, all of which is updated quarterly. The allowance is adjusted through a provision for credit losses in the Company's Unaudited Condensed Consolidated Statements of Income. For the three months ended March 31, 2026, the Company recorded an increase to the credit loss allowance of $2.2 million. The total allowance for credit losses attributable to the Company's loans receivable were $9.7 million and $7.4 million at March 31, 2026 and December 31, 2025, respectively. The balance of the loans included in Prepaid expenses and other on the accompanying Unaudited Condensed Consolidated Balance Sheets was $11.9 million and $13.5 million at March 31, 2026 and December 31, 2025, respectively, net of credit loss allowances. The balance of the loans included in Patents and other assets, net, on the accompanying Unaudited Condensed Consolidated Balance Sheets was $7.2 million and $7.9 million, at March 31, 2026 and December 31, 2025, respectively, net of credit loss allowances.

Earnings Per Share

Earnings Per Share

The Company has unvested share-based payment awards with a right to receive non-forfeitable dividends, which are considered participating securities under ASC 260, Earnings Per Share. The Company allocates earnings to participating securities and computes earnings per share using the two-class method. Under the two-class method, net income per share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, net income is allocated to both

common shares and participating securities based on their respective weighted average shares outstanding for the period. For a period of net loss, net loss is not allocated to participating securities.

The following table sets forth the computation of basic and diluted net income per common share under the two-class method for the three months ended March 31, 2026 and 2025:

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation Plans

Stock-Based Compensation Plans

As of March 31, 2026, the Company had two equity incentive plans in effect, which include the Gentex Corporation 2019 Omnibus Incentive Plan ("2019 Omnibus Plan"), and an employee stock purchase plan. Those plans and any prior material amendments thereto have previously been approved by shareholders.

The 2019 Omnibus Plan provides for the potential awards to: i) employees; and ii) non-employee directors of the Company or its subsidiaries, which potential awards may be stock options (both incentive stock options and non-qualified stock options), appreciation rights, restricted stock awards and restricted stock units, performance share awards and performance units, and other awards that are stock-based, cash-based or a combination of both. The 2019 Omnibus Plan replaced the Company's Employee Stock Option Plan, Second Restricted Stock Plan, and Amended and Restated Non-Employee Director Stock Option Plan (the "Prior Plans"), which were also approved by shareholders. Any existing awards previously granted under the Prior Plans remain outstanding in accordance with their terms and are governed by the Prior Plans as applicable.

Readers should refer to Note 5 of the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the calendar year ended December 31, 2025, for additional information related to the Prior Plans.

The Company recognized total compensation expense for share-based payments of $10.4 million for the three months ended March 31, 2026, compared to $8.7 million for the three months ended March 31, 2025, respectively. A portion of the compensation cost for share-based payment awards is capitalized as part of inventory.

2019 Omnibus Incentive Plan

The purpose of the 2019 Omnibus Plan is to attract and retain employees, officers, and directors of the Company and its subsidiaries and to motivate and provide such persons' incentives and rewards for performance. Pursuant to the

terms of the 2019 Omnibus Plan, each type of award counts against the available shares based on a predetermined conversion rate (shown in the table below). As of March 31, 2026, 13,241,091 share awards have been made under the Plan, resulting in 38,942,701 shares granted of the 45,000,000 total shares available to be issued under the Plan. The shares issued are presented net of shares from canceled/expired options and shares.

	Shares Granted	Conversion Rate	Total Shares Under 2019 Omnibus Plan
Non-Qualified Stock Options	4,841,872	1.00	4,841,872
Restricted Stock	6,656,691	4.06	27,026,165
Performance Shares	1,742,528	4.06	7,074,664
Total	13,241,091		38,942,701

Employee Stock Options

Under the 2019 Omnibus Plan and the Employee Stock Option Plan, the option exercise price equals the stock’s market price on the date of grant. The options vest after one to five years and expire after five to ten years. As of March 31, 2026, there was $3.3 million of unearned compensation cost associated with stock options granted under the 2019 Omnibus Incentive Plan and the Employee Stock Option Plan, which is expected to be recognized over the remaining vesting periods.

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions for the indicated periods:

	Three Months Ended March 31,
	2026		2025
Dividend Yield (1)	1.70	%	1.62	%
Expected volatility (2)	25.89	%	25.60	%
Risk-free interest rate (3)	3.92	%	3.96	%
Expected term of options (years) (4)	4.15		4.14
Weighted-avg. grant date fair value	$5.00		$5.35

1.Represents the Company’s estimated cash dividend yield over the expected term of option grant.

2.Amount is determined based on analysis of historical price volatility of the Company’s common stock. The expected volatility is based on the daily percentage change in the price of the stock over a period equal to the expected term of the option grant.

3.Represents the U.S. Treasury yield over the expected term of the option grant.

Restricted shares awarded under the 2019 Omnibus Plan and the Second Restricted Stock Plan entitle the shareholder to all rights of common stock ownership, except that the shares may not be sold, transferred, pledged, exchanged, or otherwise disposed of during the restriction period. The restriction period is determined by the Compensation Committee, appointed by the Board of Directors, but may not exceed ten years under the terms of such plans. As of March 31, 2026, the Company had unearned stock-based compensation of $54.1 million associated with the restricted stock grants issued under the 2019 Omnibus Plan and the Second Restricted Stock Plan. The unearned stock-based compensation related to these grants is being amortized to compensation expense over the applicable restriction periods. Compensation expense from restricted stock grants for the three months ended March 31, 2026 was $6.0 million, compared to $5.9 million for the three months ended March 31, 2025.

Performance Shares

Performance shares awarded under the 2019 Omnibus Plan are considered performance condition awards as attainment is based on the Company's performance relative to pre-established metrics. The fair value of such performance share awards was determined using the Company's average closing stock price on the twenty days preceding the date of grant. The expected attainment of the metrics for these awards is then analyzed each reporting period, and the related expense is adjusted based on expected attainment, if the then expected attainment differs from

previous expectations. The cumulative effect on current and prior periods of a change in expected attainment is recognized in the period of change.

As of March 31, 2026, the Company had unearned stock-based compensation of $17.6 million associated with these performance share grants. The unearned stock-based compensation related to these grants is being amortized to compensation expense over the applicable performance periods. Compensation expense related to these performance share grants for the three months ended March 31, 2026 was $2.9 million, compared to $1.0 million for the three months ended March 31, 2025.

As part of its objective of attracting and retaining management to fulfill the Company's strategic goals, the Compensation Committee recommended and the Board approved on February 16, 2023, a retention grant of performance share awards ("PSAs"). In addition to the retention of management, the PSAs have been granted to further align management goals with those of the Company's shareholders. For that reason, the PSAs have been granted with performance criteria and will be based upon achievement of the Company's relative total shareholder return ("TSR") over a four-year period (2023-2026), against a predetermined peer group. The grant date fair value of PSAs with TSR targets was determined using a Monte Carlo simulation. Compensation expense related to these retention grants was $0.5 million during each of the three months ended March 31, 2026 and March 31, 2025.

Employee Stock Purchase Plan

The 2022 Gentex Corporation Employee Stock Purchase Plan covering 2,000,000 shares of common stock was approved by shareholders effective July 1, 2022. Under the plan, the Company sells shares at 85% of the stock's market price at date of purchase. Under ASC 718, Compensation - Stock Compensation, the 15% discounted value is recognized as compensation expense. As of March 31, 2026, the Company has issued 804,112 shares under this plan.

Contingencies

Contingencies

The Company is periodically involved in legal proceedings, legal actions and claims arising in the normal course of business, including proceedings relating to, for example, product liability, intellectual property, safety and health, employment, regulatory, and other matters. Such matters are subject to many uncertainties and outcomes are not predictable. The Company does not believe, however, that at the current time any of these matters constitute material pending legal proceedings that will have a material adverse effect on the financial position or future results of operations or cash flows of the Company.

On April 1, 2025, the Company completed its acquisition of VOXX (see Note 16). In connection with the acquisition, VOXX as acquired, maintained responsibility for certain legal matters and royalty audits. These matters include legal proceedings in which VOXX was named a defendant prior to the acquisition date, as well as unasserted claims and other legal matters for which the underlying events or circumstances existed as of the acquisition date and for which a liability was required to be recognized under ASC 805, Business Combinations ("ASC 805"). As part of the purchase price allocation, pursuant to applicable guidance, the Company recorded provisional liabilities for these matters based on estimates of their fair values as of the acquisition date. The Company continues to monitor the status of any of the matters that remain unresolved. Any adjustments recognized after the measurement period, as a result of additional information becoming available or the resolution of these matters, will be reflected in earnings in the period in which the adjustment is identified.

On February 20, 2026, the U.S. Supreme Court struck down certain tariffs imposed under the International Emergency Economic Powers Act ("IEEPA"). Following the Supreme Court’s decision, the U.S. administration announced a new 10% global tariff under Section 122 of the Trade Act of 1974, subject to certain exceptions. The impact of these decisions on the Company remains uncertain, including the potential for refunds of IEEPA tariffs previously paid, changes in tariff levels, and/or new tariffs. The ultimate availability, timing, and amount of any potential refunds of IEEPA tariffs remains highly uncertain and is subject to further legal, regulatory, and administrative developments. Consistent with applicable GAAP, the Company has not recognized any receivable and corresponding offset to expense or asset as of March 31, 2026 related to potential refunds of IEEPA tariffs since any realization of any such recovery is dependent on uncertain future events and the Company is unable to conclude that recovery is both probable and reasonably estimable as of March 31, 2026. The Company continues to monitor and evaluate these developments and assess their potential impact on the Company’s business, financial condition, and results of operations. The Company is pursuing refunds as it determines appropriate.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

ASC 280, Segment Reporting, requires that a public business entity report financial and descriptive information about its reportable operating segments, subject to certain aggregation criteria and quantitative thresholds. Operating segments are defined by ASC 280 as components of a public business entity about which separate financial information is available that is evaluated regularly by the chief operating decision-maker ("CODM") in deciding how to allocate resources and in assessing performance. The Company's CODM is its Chief Executive Officer. The CODM evaluates performance and allocates resources based upon a number of factors, including the nature of the business, relevant industry, and profitability of the same, with the primary profit measure being income (loss) from operations of each segment. The CODM uses this information to evaluate the profitability of the Company's reportable segments and make decisions on future business plans.

The Company has identified nine distinct operating segments based on its products and internal organizational structure. These operating segments are disclosed by the Company under three reportable segments for financial reporting purposes, which are Automotive Products, Premium Audio Products, and Other. The Company's Automotive Products segment develops and manufactures digital vision and connected car products and electronics, including: interior and exterior electrochromic automatic-dimming rearview mirrors with and without electronic features; non-auto dimming rearview mirrors with and without electronic features; and other automotive electronics. The Company's Premium Audio Products segment designs, manufactures, markets, and distributes high quality audio equipment created to deliver superior sound quality and performance, including premium loudspeakers, architectural speakers,

commercial and cinema speakers, outdoor speakers, wireless and Bluetooth speakers, A/V receivers, home theater systems, soundbars, and music streaming systems. The Company's Other segment includes the operating segments of Fire Protection, Dimmable Aircraft Windows, Nanofiber, Medical, Aftermarket, Consumer Electronics, and Biometrics, which do not meet quantitative thresholds for separate disclosure pursuant to ASC 280.

The segments share many common resources, infrastructures, and assets in the normal course of business. Thus, the Company does not report assets or capital expenditures by segment to the CODM.

The following table presents net sales and the significant expense categories for the three months ended March 31, 2026 and 2025 (which did not include VOXX), respectively, that are included in reportable segment operating profit, which are regularly provided to the CODM:

Sales Incentives

Sales incentives are offered to certain customers in the form of: (1) co-operative advertising allowances; (2) market development funds; (3) volume incentive rebates; and (4) other trade allowances. The Company accounts for sales incentives in accordance with ASC 606 "Revenue from Contracts with Customers" ("ASC 606"). These sales incentives represent variable consideration provided to customers. Depending on the specific facts and circumstances, either the most likely amount or expected value methods are utilized to estimate the effect of uncertainty on the amount of variable consideration to which the Company would be entitled. The most likely amount method considers the single most likely amount from a range of possible consideration amounts, while the expected value method is the sum of the probability-weighted amounts in a range of possible consideration amounts. Both methods are based upon the contractual terms of the incentives and historical experience with each customer. Except for other trade allowances, all sales incentives also require the customer to purchase the Company's products during a specified period of time. All sales incentives require customers to claim the sales incentive within a certain time period (referred to as the "claim period") and claims are settled either by the customer claiming a deduction against an outstanding account receivable or by the customer requesting a cash payout. All costs associated with sales incentives are classified as a reduction of net sales. Although the Company makes its best estimate of such sales incentive liability, many factors, including significant unanticipated changes in the purchasing volume of its customers and the lack of claims made by customers, could have a significant impact on the sales incentives liability and reported operating results. The balance of accrued sales incentives at March 31, 2026 and December 31, 2025 was $15.0 million and $19.1 million, respectively, and is included within Accrued liabilities on the Unaudited Condensed Consolidated Balance Sheets.

BioConnect Inc.

On July 1, 2025, in the ordinary course of business, the Company completed its acquisition of BioConnect Inc. ("BioConnect"), for a purchase price of $13.0 million, subject to adjustment for working capital plus related transaction fees and expenses. BioConnect is a multi-modal biometric authentication platform provider for access control. The Company intends to utilize the acquisition to expand its reach in the biometric industry. The acquisition was accounted for under the acquisition method of accounting pursuant to ASC 805, Business Combinations ("ASC 805"), and accordingly, the results of operations and cash flows for BioConnect have been included in the Company's Unaudited Condensed Consolidated Financial Statements since July 1, 2025. BioConnect's results of operations are included within the Company's Biometrics operating segment, which is presented within its Other reportable segment.

The following summarizes the preliminary allocation of the BioConnect purchase price based on the fair value of the assets acquired and liabilities assumed, as of July 1, 2025:

Net assets acquired, excluding cash	$	12,882,730	$	—	$	12,882,730

The purchase price allocation above is preliminary. The preliminary fair values of the assets acquired were estimated with the assistance of a third-party valuation expert. The Company is in the process of refining the valuation of acquired assets and assumed liabilities, including net working capital and intangible assets, and expects to finalize the purchase price allocation no later than one year after the acquisition date, which is July 1, 2026, in accordance with applicable guidance. Finalization of the valuation during the measurement period could result in significant changes in the amounts recorded for the acquisition date fair value. The Company recorded net measurement period adjustments increasing goodwill $0.4 million during the fourth quarter of 2025, relating primarily to revised fair value estimates of developed technology and deferred tax assets. The goodwill recognized in this acquisition is primarily attributable to the assembled workforce and expected synergies from the integration of the acquired business. All of the goodwill acquired in connection with the BioConnect acquisition has been allocated to the Company's biometrics business. None of the goodwill from the BioConnect acquisition is deductible for tax purposes.

Net sales attributable to BioConnect in the Company's Unaudited Condensed Consolidated Statement of Income for the three months ended March 31, 2026, were $2.4 million. Net income attributable to BioConnect for the three months ended March 31, 2026, was $0.4 million. There were no acquisition costs incurred during the three months ended March 31, 2026, or March 31, 2025, related to this acquisition.

VOXX International Corporation

On April 1, 2025 (the "Closing Date"), the Company completed its acquisition of VOXX pursuant to the previously announced Merger Agreement. Pursuant to the terms and conditions set forth in the Merger Agreement, the Company

acquired all of the issued and outstanding shares of VOXX common stock not already owned by the Company for a purchase price of $7.50 per share, resulting in VOXX becoming a wholly owned subsidiary of Gentex as of the Closing Date. Cash consideration totaling $148.3 million was paid by the Company on the Closing Date, using cash on hand. The acquisition was accounted for under the acquisition method of accounting pursuant to ASC 805, and accordingly, the results of operations and cash flows for VOXX have been included in the Company's Unaudited Condensed Consolidated Financial Statements since the Closing Date.

Prior to obtaining a controlling interest in VOXX, the Company owned 6,463,808 shares of VOXX Class A Common Stock, or approximately 29%, and accounted for this investment using the equity method of accounting, as the Company had the ability to exercise significant influence, but not control, over VOXX. The acquisition transaction was accounted for as a business combination achieved in stages, or a step-acquisition, pursuant to ASC 805 and, as such, the Company was required to remeasure its preexisting equity interest in VOXX immediately prior to the completion of the acquisition to its estimated fair value of $48.5 million using the $7.50 per share acquisition price to determine the fair value of the equity investment. The Company previously recorded changes in fair value of the equity method investment in Investment (loss) income, net, each reporting period, and recorded a gain of $0.8 million during the three months ended March 31, 2025, in the accompanying Unaudited Condensed Consolidated Statements of Income related to VOXX. As a result, the fair value of the investment on the Closing Date was equal to the fair value of the investment on March 31, 2025, the date immediately prior to the acquisition, and no additional gain or loss was recorded on the Closing Date.

VOXX is a leading manufacturer and distributor of automotive OEM and aftermarket electronics, and consumer technologies for the global markets, as well as premium audio solutions through world-renowned brands such as Klipsch®, Onkyo®, and Integra®. The merger also included EyeLock LLC ("EyeLock®"), a majority-owned subsidiary of VOXX, which holds iris biometric technology through its 50% ownership interest in the BioCenturion joint venture. This additional interest in BioCenturion was acquired by the Company in a separate transaction as discussed below. The acquisition of VOXX is a strategic addition to the Company's portfolio of products, as VOXX's product lines will both complement the Company's existing businesses and help the Company continue to expand in the consumer technology and connected home space. The Company has also gained all access to the EyeLock® iris biometric technology, which will provide further product applications in the Gentex automotive, aerospace, and medical markets.

The following summarizes the allocation of the purchase price based on the fair value of the assets acquired and liabilities assumed, as of the Closing Date. The fair value of the Class A Common Stock acquired through this step acquisition is included in the totals presented below:

Net assets acquired, excluding cash	$	187,658,422	$	—	$	187,658,422

The fair values of the assets acquired were estimated with the assistance of a third-party valuation expert. The Company recorded net measurement period adjustments totaling $16.5 million during 2025, and during the first quarter of 2026, relating primarily to the revised fair value estimates of liabilities for certain legal and contractual contingencies, employee compensation, royalties payable, and income taxes. The goodwill recognized in this acquisition was attributable to the assembled workforce, expected synergies, and expanded market opportunities, none of which qualify for recognition as a separate intangible asset. All of the goodwill acquired in connection with the VOXX acquisition has been allocated to the Company's Premium Audio Products business. $2.9 million of the goodwill recognized in the

VOXX acquisition is deductible for tax purposes.

Net sales attributable to VOXX in the Company's Unaudited Condensed Consolidated Statement of Income for the three months ended March 31, 2026 were $88.6 million. The net income attributable to VOXX for the three months ended March 31, 2026 was $4.6 million. During the three months ended March 31, 2025, the Company incurred $879,467 in acquisition costs related to the VOXX acquisition, which has been expensed as incurred in the "Selling, general & administrative" section of its Unaudited Condensed Consolidated Statement of Income. No additional acquisition costs were incurred during the three months ended March 31, 2026, related to this acquisition. VOXX's results of operations are included in the Consolidated Financial Statements of the Company within the Automotive, Premium Audio, Aftermarket, Consumer Electronics, and Biometrics operating segments. The Aftermarket, Consumer Electronics, and Biometrics operating segments are presented within the Company's Other reportable segment.

The non-controlling interests included in the net assets acquired in the transaction were comprised of a redeemable non-controlling interest in VOXX's Onkyo subsidiary, and a non-redeemable non-controlling interest in its EyeLock® subsidiary. In conjunction with VOXX's acquisition of Onkyo, a joint venture was formed between VOXX's wholly-owned Premium Audio Company ("PAC") subsidiary and its partner Sharp Corporation ("Sharp"). PAC owns 77.2% of the joint venture and has an 85.1% voting interest and Sharp owns 22.8% of the joint venture and has a 14.9% voting interest. The joint venture agreement between PAC and Sharp contains a put/call option, whereby Sharp has the right to put its interest in the joint venture back to VOXX and VOXX has the right to call Sharp’s ownership interest in the joint venture at any time after the approval of Onkyo’s annual financial statements for the year ending February 28, 2025, at a purchase price based on a formula as defined in the joint venture agreement.

The Onkyo non-controlling interest has been classified as redeemable non-controlling interest outside of equity on the accompanying Unaudited Condensed Consolidated Balance Sheet as the exercise of the put option is not within VOXX’s control. The following table provides the rollforward of the redeemable non-controlling interest for the three months ended March 31, 2026:

	Redeemable Non-controlling Interest
Balance at January 1, 2026	$	3,102,213
Net loss attributable to non-controlling interest	(34,084)
Comprehensive income attributable to non-controlling interest	424,415
Foreign currency translation	(471,054)
Balance at March 31, 2026	3,021,490

As of April 1, 2025, the net assets acquired in the VOXX transaction also included VOXX's non-redeemable non-controlling interest in its EyeLock® subsidiary. On August 18, 2025, the Company acquired the remaining equity interests in EyeLock® from its minority owners for cash consideration totaling $0.1 million.

In November 2024, the Company, in the ordinary course of business, acquired GalvanEyes LLC ("GalvanEyes"), which is the managing partner and 50% owner of the BioCenturion joint venture with Eyelock®. In conjunction with the acquisition of VOXX on April 1, 2025, the Company acquired VOXX's interest in BioCenturion through its majority ownership of Eyelock for cash consideration of $4.1 million.

Accounting Policies [Abstract]

Basis of Presentation

Basis of PresentationThe accompanying Unaudited Condensed Consolidated Financial Statements of Gentex Corporation and Subsidiaries ("Gentex" or the "Company") included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission as defined in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 270 for interim financial information, and in accordance with financial standards generally accepted in the United States of America ("GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations, although the Company 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 Company's 2025 annual report on Form 10-K. In the opinion of management, the accompanying Unaudited Condensed Consolidated Financial Statements contain all adjustments considered necessary for a fair presentation of the financial position of the Company as of March 31, 2026, and the results of operations and cash flows for the interim periods presented.

Adoption of New Accounting Standards

Adoption of New Accounting Standards

In March 2024, the Securities and Exchange Commission ("SEC") issued Final Rule No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors." If such rule becomes effective, the rule will require disclosure of climate-related information outside of the audited financial statements and disclosure in the footnotes to such financial statements addressing specified financial statement effects of severe weather events and other natural conditions above certain financial thresholds, certain carbon offsets and renewable energy credits or certificates, if material. Such disclosure requirements were scheduled to begin phasing in for fiscal years beginning on or after January 1, 2025. On April 4, 2024, the SEC exercised its discretion to voluntarily stay the effective date of the final rules pending completion of certain judicial review. In 2025, the SEC withdrew its defense of the climate disclosure rules and litigation has been held in abeyance. The SEC has launched a formal review, inviting public comment, with an eye toward facilitating disclosure of consistent, comparable, and reliable information on climate change. Though compliance with such rules is not currently required, and it is unclear when or if compliance will be required, the Company continues to evaluate the potential impact of compliance, as well as compliance with similar rules of other jurisdictions.

In November 2024, the FASB issued ASU No. 2024-03, "Disaggregation of Income Statement Expenses (Subtopic 220-40)." The ASU requires public business entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Companies have the option to apply the guidance either on a retrospective or prospective basis, and early adoption is permitted. In January 2025, the FASB issued ASU No. 2025-01, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date." This ASU amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of adopting these ASU's on the Consolidated Financial Statements and related disclosures.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity ("VIE"), which provides clarifying guidance on determining the accounting acquirer in certain transactions involving VIE's. The update aims to improve consistency and comparability in financial reporting. The guidance will be effective for annual periods beginning after December 15, 2026, including interim periods within those annual periods. Early adoption is permitted. Upon adoption, the guidance will be applied prospectively. The Company is currently evaluating the provisions of the guidance and the impact on its future Consolidated Financial Statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which introduces a practical expedient for the application of the current expected credit loss model to current accounts receivable and contract assets in which all entities can assume that current conditions as of the balance sheet date do not change for the remaining life of the assets. This ASU was effective for the Company in the first quarter of 2026 and did not have a material impact the Company's Consolidated Financial Statements and disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU updates the cost capitalization threshold for internal-use software development costs by removing all references to software project development stages and providing new guidance on how to evaluate whether the probable-to-complete recognition threshold has

been met. ASU 2025-06, which can be applied prospectively, retrospectively, or with a modified transition approach, is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and disclosures.

In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging - Hedge Accounting Improvements (Topic 815), which amends certain aspects of the hedge accounting guidance to better align financial reporting with the economics of an entity's risk management activities. ASU 2025-09 is effective for annual and interim periods beginning after December 15, 2026. Early adoption is permitted and is effective on a prospective basis. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements ("ASU 2025-11"). This ASU enhances consistency in interim reporting for all entities by clarifying interim disclosure requirements and the form and content of interim financial statements in accordance with GAAP. ASU 2025-11, which can be applied prospectively or retrospectively to any and all prior periods presented in the financial statements, is effective for the interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its Consolidated Financial Statements and related disclosures.
