Exhibit 99.1

GENTEX REPORTS FIRST QUARTER 2026 FINANCIAL RESULTS

ZEELAND, MI -- (GLOBE NEWSWIRE - April 24, 2026) - Gentex Corporation (NASDAQ: GNTX), a leading supplier of digital vision, connected car, dimmable glass, fire protection technologies, medical devices, and consumer electronics, today reported financial results for the three months ended March 31, 2026.

First Quarter 2026 Highlights

•Net sales: Consolidated $675.4 million; core Gentex (ex‑VOXX) $586.8 million

•Gross margin: Consolidated 33.8%; core Gentex (ex‑VOXX) 34.0%

•Consolidated Income from operations: (GAAP) $123.7 million; core Gentex $117.9 million; adjusted income from operations (non‑GAAP) for core Gentex $121.4 million

•Net income attributable to Gentex: (GAAP) $98.5 million; adjusted net income (non‑GAAP) $103.7 million

•Earnings per diluted share attributable to Gentex: (GAAP) $0.46; adjusted earnings per diluted share (non‑GAAP) $0.48

•Share repurchases: 3.3 million shares repurchased during the quarter for a total of $71.6 million

Financial Summary

For the first quarter of 2026, the Company reported consolidated net sales of $675.4 million, a 17% increase compared to net sales of $576.8 million in the first quarter of 2025, which did not include VOXX International Corporation ("VOXX"). During the first quarter of 2026, VOXX contributed $88.6 million of revenue, while core Gentex revenue totaled $586.8 million, representing a 2% quarter-over-quarter increase despite global light vehicle production that was down over 3% compared to the first quarter of 2025. “Core Gentex revenue growth in the quarter was driven by advanced feature strength in several regions that helped offset lower light vehicle production and continuing unit volume headwinds. As an example, North American revenue increased approximately 6% year‑over‑year despite a 2% decline in light vehicle production in that region compared to the first quarter of 2025. This outperformance was driven primarily by continued growth and penetration of Full Display Mirror ("FDM") shipments. In Europe, Japan, and Korea, auto-dimming mirror unit shipments declined approximately 8%

quarter‑over‑quarter; however, revenue for these combined regions declined only 2%, reflecting a favorable shift in product mix, driven by the successful launch and ramp of one of our key In-Cabin-Monitoring-System ("ICMS") platforms in Europe and continued growth of FDM. In China, revenue in the first quarter of 2026 totaled approximately $28 million, a 29% decline quarter-over-quarter, reflecting the ongoing impact of tariffs and counter‑tariff actions on our China business. Given the difficult market conditions for many of our customers, the Company’s revenue growth continues to be driven by expanding electronic content and new technologies,” said Steve Downing, President and CEO. “Another bright spot during the first‑quarter was VOXX revenue, which was approximately 9% above our beginning of quarter forecast, driven primarily by stronger‑than‑anticipated performance in the Premium Audio segment," remarked Downing.

For the first quarter of 2026, the Company's consolidated gross margin was 33.8%, compared to a gross margin of 33.2% for the first quarter of 2025, which did not include VOXX. The core Gentex gross margin in the first quarter of 2026 was 34.0%, representing an 80 basis-point increase over the first quarter of 2025. When compared with the first quarter of 2025, the Company's gross margin this quarter was positively impacted by operational efficiencies and favorable product mix, partially offset by the negative effect of tariff-related costs and commodity price increases. Compared to the first quarter of last year, the Company delivered nearly 200 basis points of operational gross margin improvement, driven by favorable product mix and strong execution, despite the headwinds associated with tariffs and commodity pricing. “The gross margin was slightly below our forecast due to the impact of tariffs and precious metals pricing that is up significantly versus the same time last year, and yet we were able to increase the core Gentex gross margin by 80 basis points versus the first quarter of last year," said Downing.

Consolidated operating expenses during the first quarter of 2026 were $105.0 million, compared to operating expenses of $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. Total operating expenses for the quarter were also impacted by intangible asset impairment charges of $2.8 million. 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 certain impairment charges, acquisition related costs, and severance costs in each of the quarters. "The

Company has been incredibly busy launching some of the most complex and exciting technologies in the Company’s history. This includes our fourth generation of FDM, new CMOS imaging sensors, ICMS, dimmable visors and large area devices, as well as many new launches in the VOXX automotive and premium audio product lines, all while managing our customers' increased focus and criteria for cyber security on many of our latest products. While the teams are incredibly busy with this workload, the Company has remained focused on managing operating expenses. We are actively leveraging all available tools to meet customer deliverables with only modest quarter‑over‑quarter growth in operating expenses,” said Gentex COO and CTO Neil Boehm.

Consolidated income from operations for the first quarter of 2026 was $123.7 million, compared to income from operations of $113.0 million for the first quarter of 2025, which did not include VOXX. Core Gentex income from operations was $117.9 million in the first quarter of 2026, a 4% improvement compared with the first quarter of 2025. On a non-GAAP basis, core Gentex adjusted income from operations was $121.4 million in the first quarter of 2026, compared to $116.8 million in the first quarter of 2025, when adjusting for the impact of certain impairment charges, acquisition related costs, and severance costs in each of the quarters.

Total other loss was $5.6 million during the first quarter of 2026, compared to income of $0.6 million in the first quarter of 2025. The year-over-year decline was primarily driven by lower investment income, as well as impairment charges and credit loss reserves related to certain technology investments and loans receivable.

During the first quarter of 2026, the Company had an effective tax rate of 16.6%, compared to an effective tax rate of 16.5% during the first quarter of 2025.

Consolidated net income attributable to Gentex for the first quarter of 2026 was $98.5 million, driven by higher quarter over quarter sales and improved profitability, compared to $94.9 million in the first quarter of 2025, which did not include VOXX. 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.

Consolidated earnings per diluted share attributable to Gentex for the first quarter of 2026 were $0.46, 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, 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.

Revenue By Category

Gentex Automotive

Gentex Automotive net sales were $566.2 million in the first quarter of 2026, up from $563.9 million in the first quarter of 2025, demonstrating revenue growth despite a quarter over quarter decline in light vehicle production and in base auto‑dimming mirror unit shipments. The quarter over quarter increase in net sales reflects favorable product mix, new technology launches, and content gains with customers.

Gentex Other

Net sales from Gentex’s Other product lines, which include dimmable aircraft windows, fire protection products, medical devices, and biometrics, were $20.6 million in the first quarter of 2026, compared to $12.9 million in the first quarter of 2025, which represents an increase of nearly 60%. This growth was driven by quarter over quarter increases of $3.4 million in aircraft window sales and $2.1 million in each of fire protection products and biometric net sales.

VOXX

VOXX net sales contributed $88.6 million during the first quarter of 2026. One year after the close of the VOXX acquisition, the integration is well under way and the VOXX business has now achieved profitability. The focus for the next twelve months will be on scaling product launches, expanding sales

channels, and strengthening market position, while at the same time, improving margins and continuing to manage operating expenses.

Share Repurchases

During the first quarter of 2026, the Company repurchased 3.3 million shares of its common stock at an average price of $22.01 per share, for a total of $71.6 million. As of March 31, 2026, the Company has approximately 32.6 million shares remaining available for repurchase pursuant to its previously announced share repurchase plan. The Company intends to continue to repurchase additional shares of its common stock in the future in support of the previously disclosed capital allocation strategy, but share repurchases will vary from time to time and will take into account macroeconomic issues, market trends, and other factors that the Company deems appropriate.

Future Estimates

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). The S&P Global mobility forecast for 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 vehicle production volumes from S&P Global Mobility for the second quarter of 2026 and calendar years 2026 and 2027 are shown below:

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 is making certain changes to its full-year 2026 guidance. The updated 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)

2027 Revenue Guidance

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 has updated its expected calendar‑year 2027 revenue to range between $2.80 billion and $2.90 billion.

International Emergency Economic Powers Act ("IEEPA") Tariffs

As it relates to the recent invalidation of the IEEPA tariffs by the U.S. Supreme Court, the Company has not recognized any potential refund in its first‑quarter results. The Company is in the process of assessing the potential impact of such invalidation, and its eligibility and process for seeking refunds. As of March 31, 2026, the Company estimates that approximately $15 million of tariff costs have been capitalized in inventory associated with IEEPA tariffs, which had 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 to date. Given the evolving situation, the Company has not recognized any potential refunds because of the difficulty in predicting

whether any tariff refunds will be available, or whether the U.S. Customs and Border Protection Agency will contest any tariff refund claims made by the Company.

Closing Remarks

“Based on first‑quarter performance and our current forecast for the remainder of the year, the Company is increasing its current revenue guidance for the year, while maintaining the full year gross margin guidance. New tariffs, which are currently temporary, have been reflected in our outlook as if effective for the full year. The Company is also facing new and ongoing cost pressures from key commodities including a number of precious metals, petroleum‑based products, and memory components. These headwinds have not resulted in material supply chain disruptions to date, and we will continue to pursue customer reimbursement opportunities and internal VA/VE projects to reduce the impact these headwinds could have on gross margin performance. At the one-year anniversary of the VOXX acquisition, we are pleased with the cost improvements accomplished and how the teams continue to further integrate. We are also proud of the progress made across the organization, as we begin to see the benefits of a shared strategy and expanded capabilities across the combined businesses. As we look ahead, we remain focused on the disciplined execution of the many technology launches, development initiatives, and R&D projects that are currently underway. Such focus is needed to accelerate growth in a market where light vehicle production challenges remain. These technology launches are designed to provide above market growth over the next few years and when combined with our disciplined approach to managing operating expenses, we believe we have a winning formula to create shareholder returns. We are also encouraged by the increased interest from our customers on Gen4 FDM, ICMS, dimmable visor and large area devices, as well as several ongoing discussions with customers around becoming a strategic, high-volume, electronics supplier with a US operating footprint to help OEM customers mitigate tariff exposure and geo-political risks that exist in the current supply base," said Downing.
