Forward-Looking Statements All statements made herein that are not historical facts should be considered as forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements involve known and unknown risks, uncertainties and other factors that may cause actual results to differ materially. These statements include, but are not limited to, statements regarding the process to divest the legacy WESCO Utility and Datacom businesses in Canada, including the expected length of the process, the expected benefits and costs of the transaction between WESCO and Anixter International Inc., including anticipated future financial and operating results, synergies, accretion and growth rates, and the combined company's plans, objectives, expectations and intentions, statements that address the combined company's expected future business and financial performance, and other statements identified by words such as "anticipate," "plan," "believe," "estimate," "intend," "expect," "project," "will" and similar words, phrases or expressions. These forward-looking statements are based on current expectations and beliefs of WESCO's management, as well as assumptions made by, and information currently available to, WESCO's management, current market trends and market conditions and involve risks and uncertainties, many of which are outside of WESCO's and WESCO's management's control, and which may cause actual results to differ materially from those contained in forward-looking statements. Accordingly, you should not place undue reliance on such statements. Those risks, uncertainties and assumptions include the risk of any unexpected costs or expenses resulting from the transaction, the risk of any litigation or post-closing regulatory action relating to the transaction, the risk that the transaction could have an adverse effect on the ability of the combined company to retain customers and retain and hire key personnel and maintain relationships with its suppliers, customers and other business relationships and on its operating results and business generally, the risk that problems may arise in successfully integrating the businesses of the companies or that the combined company could be required to divest one or more businesses, which may result in the combined company not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve synergies or other anticipated benefits of the proposed transaction or it may take longer than expected to achieve those synergies or benefits, the risk that the leverage of the company may be higher than anticipated, the impact of natural disasters, health epidemics and other outbreaks, especially the outbreak of COVID-19 since December 2019, which may have a material adverse effect on the combined company's business, results of operations and financial conditions, the risk that the divesture of the legacy WESCO Utility and Datacom businesses in Canada may take longer than expected and other important factors that could cause actual results to differ materially from those projected. All such factors are difficult to predict and are beyond each company's control. Additional factors that could cause results to differ materially from those described above can be found in WESCO's Annual Report on Form 10-K for the fiscal year ended December 31, 2019 and WESCO's other reports filed with the U.S. Securities and Exchange Commission ("SEC"). Non-GAAP Measures In addition to the results provided in accordance with U.S. Generally Accepted Accounting Principles ("U.S. GAAP") above, this presentation includes certain non-GAAP financial measures. These financial measures include organic sales growth, gross profit, gross margin, decremental operating margin, earnings before interest, taxes, depreciation and amortization (EBITDA), adjusted EBITDA, pro forma adjusted EBITDA, financial leverage, pro forma financial leverage, free cash flow, adjusted income from operations, adjusted operating margin, adjusted net income, and adjusted earnings per diluted share. The Company believes that these non-GAAP measures are useful to investors as they provide a better understanding of sales performance, and the use of debt and liquidity on a comparable basis. Additionally, certain non-GAAP measures either focus on or exclude transactions impacting comparability of results, allowing investors to more easily compare the Company's financial performance from period to period. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated above. 2
