•	The company’s current share repurchase authorization expires on April 30, 2020, which will be replaced with a new one million share authorization effective through April 30, 2021. The company is suspending share repurchase activity for the near-term.


•	The company will pay a cash dividend on its common stock of $0.48 per share on June 4, 2020 to shareholders of record as of May 21, 2020. If the macro environment disruption intensifies or is sustained, the Board of Directors may consider a change in the dividend.

“These are challenging times and our company is doing its part to help flatten the curve in response to the COVID-19 pandemic,” said Dave Heinzmann, Littelfuse President and Chief Executive Officer. “Our first priority is our global associates - to protect the health and well-being of them, their families, and the communities where we operate, while working to preserve jobs. Our second priority is to continue to support and serve the critical needs of our customers. Our third priority is the long-term financial health of the business. Over the past several years, we have maintained a conservative financial position, which is even more important during these uncertain times. We have made structural changes over the years to strengthen our business, and along with decisive actions we have taken over the past several weeks, we expect to come out stronger on the other side of this challenge.”

2020 Outlook*:


•	For the second quarter of 2020, the company expects net sales to be down approximately 20% sequentially, with an approximately 45% adjusted operating income fall through, reflecting the impact of COVID-19 on the supply chain and end demand environment


•	The company is withdrawing its full year 2020 guidance issued on January 29 due to limited visibility of COVID-19 impacts

*Littelfuse provides an estimate regarding operating income on a non-GAAP basis. GAAP items excluded 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 estimate the excluded items in order to provide the most directly comparable GAAP financial measure without unreasonable efforts.

Non-GAAP Financial Measures

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

The company believes that organic sales growth, adjusted operating income, adjusted operating margin, adjusted EBITDA, adjusted EBITDA margin, adjusted diluted earnings per share, 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 free cash flow is a useful measure of its ability to generate cash. The company believes that consolidated total debt, consolidated EBITDA, and ratio of consolidated total 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.
