Second Quarter of 2022*

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

•Net sales in the range of $594 to $608 million, the midpoint of which represents 15% growth over the prior year and 7% organic growth

•Adjusted diluted EPS in the range of $3.95 to $4.11, the midpoint of which represents 18% growth over the prior year

•An adjusted effective tax rate of approximately 16.5%

•The company’s forecast includes an approximately 300 basis point year-over-year sales headwind from COVID-related lockdowns in China, as well as costs to support its operations and employees

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.

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 January 1, 2022. 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 January 1, 2022, 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.

Non-GAAP Financial Measures

The information included in this press release includes the non-GAAP financial measures of organic net sales 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, consolidated total gross debt, consolidated EBITDA (as defined in the private placement senior notes), and ratio of consolidated total gross debt to consolidated EBITDA. 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

Page 4

The company believes that organic net sales 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 our core financial performance and facilitate comparisons to historical results of operations, by excluding items that are not related directly to the underlying performance of our fundamental business operations or were not part of our 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 consolidated total gross debt, consolidated EBITDA, and ratio of consolidated total gross debt to consolidated EBITDA 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 our definitions of these non-GAAP financial measures may differ from those terms as defined or used by other companies.
