WESCO INTERNATIONAL INC

The following is an additional risk factor to those previously disclosed in Item 1A. to Part 1 of Wesco’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Divestitures are subject to various risks and uncertainties.

On February 23, 2024 we announced the divestiture of our Wesco Integrated Supply business, and the transaction closed on April 1, 2024. Divestitures involve risks and uncertainties, such as the separation of assets that are being sold, employee distraction, potential disruptions to customer and vendor relationships, and tax obligations or loss of tax benefits. If we are unable to successfully transition divested businesses, our business and financial results could be negatively impacted. After we divest a business, we may retain exposure on financial or performance guarantees and other contractual, employment, or severance obligations, and potential liabilities that may arise under law because of the disposition or the subsequent failure of an acquirer. Purchase price adjustments could be unfavorable and other future proceeds owed to us as part of these transactions could be lower than we expect. In addition, the divestiture of any business could negatively impact our profitability, resulting in the loss of sales or income, or a decrease in cash flows.
