The statements in this presentation 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. These statements may involve risks and uncertainties, including, but not limited to, risks and uncertainties relating to general economic conditions; the severity and duration of the COVID-19 pandemic and the measures taken in response thereto and the effects of those items on the company’s business; product demand and market acceptance; the impact of competitive products and pricing; product quality problems or product recalls; capacity and supply difficulties or constraints; coal mining exposures reserves; failure of an indemnification for environmental liability; exchange rate fluctuations; commodity price fluctuations; the effect of Littelfuse, Inc.'s ("Littelfuse" or the "Company") accounting policies; labor disputes; restructuring costs in excess of expectations; pension plan asset returns less than assumed; integration of acquisitions; uncertainties related to political or regulatory changes; 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 presentation 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 26, 2020. 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 26, 2020, 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 Measure. The information included in this presentation includes the non-GAAP financial measure of free cash flow. A reconciliation of this non-GAAP financial measure to the most directly comparable GAAP financial measure is set forth in the appendix.
