The Company cautions that its forward-looking statements involve risks and uncertainties, and while we believe that our expectations for the future are reasonable in view of currently available information, you are cautioned not to place undue reliance on our forward- looking statements. Actual results or events may differ materially from those indicated as a result of various important factors. Such factors may include, among other things, the extent and duration of the disruption to our business operations caused by the global health crisis associated with the COVID-19 outbreak, including the effects on the financial health of our business partners and customers, on supply chains and our suppliers, on vehicle miles driven as well as other metrics that affect our business, and on access to capital and liquidity provided by the financial and capital markets; the Company’s ability to maintain compliance with its debt covenants; the Company's ability to successfully integrate acquired businesses into the Company and to realize the anticipated synergies and benefits; the Company's ability to successfully divest businesses and realize the expected benefits of those divestitures; the Company's ability to successfully implement its business initiatives in its two business segments; changes in demand for the Company's products; the ability to maintain favorable supplier arrangements and relationships; disruptions in our suppliers' operations, including the impact of COVID-19 on our suppliers as well as our supply chain; changes in national and international legislation or government regulations or policies, including changes to import tariffs, short term government subsidies, and the unpredictability of such changes and their impact to the Company and its suppliers and customers, data security policies and requirements as well as privacy legislation; changes in general economic conditions, including unemployment, inflation (including the impact of tariffs) or deflation and the United Kingdom's exit from the European Union and the unpredictability of the impact following such exit; changes in tax laws, regulations, treaties and policies, including the interpretation and enforcement of any of the foregoing; volatile exchange rates; volatility in oil prices; significant cost increases, such as rising fuel and freight expenses; the Company's ability to successfully attract and retain employees in the current labor market; uncertain credit markets and other macroeconomic conditions; competitive product, service and pricing pressures; failure or weakness in our disclosure controls and procedures and internal controls over financial reporting, including as a result of the work from home environment; the uncertainties and costs of litigation; disruptions caused by a failure or breach of the Company's information systems, and the other risks and uncertainties discussed in the Company’s latest SEC filings.

Actual results may vary materially and, as such, you are cautioned not to place undue reliance on these forward-looking statements.

NON-GAAP MEASURES: This presentation contains adjusted net income from continuing operations, adjusted diluted earnings per share from continuing operations, adjusted tax rate, adjusted gross profit, adjusted operating and non-operating expenses, net sales excluding divestitures, segment profit excluding divestitures, segment profit margin excluding divestitures, and free cash flow, which are financial measures that are not derived in accordance with generally accepted accounting principles ("GAAP"). The Company considers these non- GAAP measures useful to investors because they provide greater transparency into management’s view and assessment of the Company’s core operating performance. These measures are widely used by analysts, investors and competitors in our industry, although our calculation of the measure may not be comparable to similar measures disclosed by other companies, because not all companies and analysts calculate these measures in the same manner. The Company does not, nor does it suggest investors should, consider non-GAAP financial measures superior to, in isolation from, or as a substitute for, GAAP financial information. The Company has included reconciliations of this additional information to the most comparable GAAP measure in the appendix of this presentation.
