&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• GAAP operating margin of 15.4%, +270 bps; Adjusted EBITDA margin of 22.9%, +280 bps

CHICAGO, May 6, 2026 - Littelfuse, Inc. (NASDAQ: LFUS), a leader in developing smart solutions that enable safe and efficient electrical energy transfer, today reported financial results for the first quarter ended March 28, 2026:

"Our teams delivered a strong start to the year, with first quarter results exceeding our expectations," said Greg Henderson, Littelfuse President and Chief Executive Officer. "We capitalized on solid market demand and executed well on our strategic priorities while leveraging our leadership in safe and efficient electrical energy transfer. Across all segments, we delivered growth and margin expansion, and we remain focused on driving growth opportunities, broadening our solutions portfolio, and advancing our operational excellence initiatives."

**<u>Second Quarter of 2026\*</u>**

"Looking ahead to the second quarter, we expect approximately 14% total revenue growth versus the prior year, supported by a strong backlog, continued customer momentum, and contributions from the Basler acquisition. Demand strength remains broad based, and we continue to partner closely with our customers to drive the ongoing evolution to higher power and higher energy density solutions."

Based on current market conditions, for the second quarter the company expects,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net sales in the range of $690 - $710 million, adjusted diluted EPS in the range of $3.65 – $3.85 and an adjusted effective tax rate of 21% - 22%

*\*Littelfuse provides guidance on a non-GAAP (adjusted) basis. GAAP items excluded from guidance may include the after-tax impact of items including acquisition and integration costs, restructuring, impairment and other charges, certain purchase accounting adjustments, non-operating foreign exchange adjustments and significant and unusual items. These items are uncertain, depend on various factors, and could be material to results computed in accordance with GAAP. Littelfuse is not able to forecast the excluded items in order to provide the most directly comparable GAAP financial measure without unreasonable efforts.*

**<u>May 14, 2026 Investor Day</u>**

The Company will host an Investor Day in New York City on Thursday, May 14, 2026. Greg Henderson, President and CEO, Abhi Khandelwal, Executive Vice President and CFO, and other members of the executive leadership team will present an in-depth review of the company's business strategy, growth drivers, and financial objectives. The event will also feature interactive Q&A sessions.

Presentations are expected to begin at 9:00 a.m. ET and conclude at 12:00 p.m. ET.

The live webcast, as well as the presentation materials, will be available to the public on the day of the event via the Investor Relations section of Littelfuse.com. The webcast replay will be available within 24 hours of the event and will be archived for 12 months.

**<u>First Quarter 2026 Segment Performance Highlights</u>**

*Electronics Segment*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net sales for the first quarter 2026 increased +18%. Organic sales increased +15% driven by improved passive products (+22% organic) sales. Semiconductor product (+8% organic) sales also contributed to growth driven by increased protection semiconductor volumes which more than offset lower power semiconductor sales. Favorable FX contributed +3% to growth.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA margin for the first quarter 2026 increased to 25.1% (+300 bps) primarily due to strong passive products and protection volume leverage.

*Transportation Segment*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net sales for the first quarter 2026 increased +5% as organic sales increased +1% while favorable FX contributed +4% to growth. Organic sales growth benefited from improved passenger vehicle organic sales (+4% organic) and favorable pricing, which offset lower commercial vehicle sales (-1% organic). Passenger vehicle strength was driven by content expansion, more than offsetting lower global passenger car builds and sensor declines in the first quarter. Lower commercial vehicle organic sales reflected the previously disclosed exit of the marine business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA margin for the first quarter 2026 increased to 19.1% (+200 bps) driven by volume leverage and operational execution.

------

*Industrial Segment*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net sales for the first quarter 2026 increased +45%. Organic sales increased +5% as improved grid & utility infrastructure and data center demand, along with favorable pricing, more than offset lower HVAC demand. The Basler acquisition and favorable FX also contributed +39% and +1% to growth, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA margin for the first quarter 2026 increased to 21.9% (+340 bps) driven by favorable volume leverage and mix.

**<u>Dividend</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company will pay a cash dividend on its common stock of $0.75 per share on June 4, 2026, to shareholders of record as of May 21, 2026.

**<u>Conference Call and Webcast Information</u>**

Littelfuse will host a conference call on Wednesday, May 6, 2026, at 8:00 a.m. Central Time to discuss the results. The call will be broadcast and available for replay at Littelfuse.com. A slide presentation is available in the Investor Relations section of the company's website at Littelfuse.com.

***<u>"Safe Harbor" Statement under the Private Securities Litigation Reform Act of 1995</u>***

The statements in this press release that are not historical facts are intended to constitute "forward-looking statements" entitled to the safe-harbor provisions of the Private Securities Litigation Reform Act. Such statements are based on Littelfuse, Inc.'s ("Littelfuse" or the "Company") current expectations and are subject to a number of factors and uncertainties, which could cause actual results to differ materially from those described in the forward-looking statements. These risks, uncertainties and other factors include, but are not limited to, risks and uncertainties relating to general economic conditions; product demand and market acceptance; economic conditions; the impact of competitive products and pricing; product quality problems or product recalls; capacity and supply difficulties or constraints; coal mining exposures reserves; cybersecurity matters; failure of an indemnification for environmental liability; changes in import and export duty and tariff rates; exchange rate fluctuations; commodity price fluctuations; the effect of the Company's accounting policies; labor disputes and shortages; restructuring costs in excess of expectations; pension plan asset returns less than assumed; uncertainties related to political or regulatory changes; integration of acquisitions may not be achieved in a timely manner, or at all; limited realization of the expected benefits from investment and strategic plans; the risk that expected benefits, synergies and growth prospects of the transaction with Basler may not be achieved in a timely manner, or at all; and other risks which may be detailed in the company's Securities and Exchange Commission filings. Should one or more of these risks or uncertainties materialize or should the underlying assumptions prove incorrect, actual results and outcomes may differ materially from those indicated or implied in the forward-looking statements. This release should be read in conjunction with information provided in the financial statements appearing in the company's Annual Report on Form 10-K for the year ended December 27, 2025.

Further discussion of the risk factors of the company can be found under the caption "Risk Factors" in the company's Annual Report on Form 10-K for the year ended December 27, 2025, and in other filings and submissions with the SEC, each of which are available free of charge on the company's investor relations website at investor.littelfuse.com and on the SEC's website at www.sec.gov. These forward-looking statements are made as of the date hereof. The company does not undertake any obligation to update, amend or clarify these forward-looking statements to reflect events or circumstances after the date hereof or to reflect the availability of new information.

***<u>Non-GAAP Financial Measures</u>***

The information included in this press release and other materials filed with the SEC may include non-GAAP financial measures including organic net sales (decline) growth, adjusted operating income, adjusted operating margin, adjusted EBITDA, adjusted EBITDA margin, adjusted diluted earnings per share, adjusted income taxes, adjusted effective tax rate, free cash flow, net debt, consolidated EBITDA, and consolidated net leverage ratio (as defined in the credit agreement). Many of these non-GAAP financial measures exclude the effect of certain expenses and income not related directly to the underlying performance of our fundamental business operations. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures is set forth in the attached schedules. The company believes that organic net sales (decline) growth, adjusted operating income, adjusted operating margin, adjusted EBITDA, adjusted EBITDA margin, adjusted diluted earnings per share, adjusted income taxes, and adjusted effective tax rate provide useful information to investors regarding its operational performance because they enhance an investor's overall understanding of the company's core financial performance and facilitate comparisons to historical results of operations, by excluding items that are not related directly to the underlying performance of its fundamental business operations or were not part of the company's business operations during a comparable period. The company believes that free cash flow is a useful measure of its ability to generate cash. The company believes that net debt, consolidated EBITDA, and consolidated net leverage ratio are useful measures of its credit position. The company believes that all of these non-GAAP financial measures are commonly used by financial analysts and others in the industries in which we operate, and thus further provide useful information to investors. Management additionally uses these measures when assessing the performance of the business and for business planning purposes. Note that the company's definitions of these non-GAAP financial measures may differ from those terms as defined or used by other companies.
