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 expected completion and timing of the proposed transaction between WESCO International, Inc.

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. Certain of these risks are set forth in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2019, as well as WESCO’s other reports filed with the U.S. Securities and Exchange Commission (the "SEC").

These risks, uncertainties and assumptions also include the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the proposed transaction between WESCO and Anixter that could reduce anticipated benefits or cause the parties to abandon the proposed transaction, the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, the risk that the parties may not be able to satisfy the conditions to the proposed transaction in a timely manner or at all, risks related to disruption of management time from ongoing business operations due to the proposed transaction, the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of WESCO's common stock, the risk of any unexpected costs or expenses resulting from the proposed transaction, the risk of any litigation relating to the proposed transaction, the risk that the proposed transaction and its announcement could have an adverse effect on the ability of WESCO or Anixter to retain customers and retain and hire key personnel and maintain relationships with their suppliers, customers and other business relationships and on their operating results and businesses generally, the risk that the pending proposed transaction could distract management of both entities and they will incur substantial costs, the risk that problems may arise in successfully integrating the businesses of the companies, 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 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 WESCO's control.
