WESCO INTERNATIONAL INC Segments Disclosure
16. BUSINESS SEGMENTS
The Company has operating segments comprising three strategic business units: EES, CSS and UBS. These operating segments are equivalent to the Company’s reportable segments.
The CODM allocates resources and evaluates the performance of the Company’s reportable segments based on adjusted earnings before interest, taxes, depreciation and amortization (“adjusted EBITDA”), which is the Company’s measure of segment profit or loss. The CODM considers budget-to-actual and year-over-year variances for net sales and adjusted EBITDA when making decisions about allocating resources to the segments.
The Company incurs corporate costs primarily related to treasury, tax, information technology, legal and other centralized functions. The Company also has various corporate assets. Segment assets may not include jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense and other non-operating items are either not allocated to the segments or reviewed on a segment basis. Corporate expenses and assets not directly identifiable with a reportable segment are reported in the tables below to reconcile the reportable segments to the consolidated financial statements.
As previously described in Note 2, “Accounting Policies,” the reportable segment information for the years ended December 31, 2024 and 2023 for the EES and CSS reportable segments has been recast to conform to the current year presentation.
The following is a description of each of the Company’s reportable segments and their business activities.
Electrical & Electronic Solutions
The EES segment serves customers in over 50 countries and supplies a broad range of products and solutions primarily to construction, industrial and original equipment manufacturer (“OEM”) customers. The EES product portfolio includes a broad range of electrical equipment and supplies, automation and connected devices (the “Internet of Things” or “IoT”), security, lighting, wire and cable, safety, and maintenance, repair and operating (“MRO”) products from industry-leading manufacturing partners. The EES service portfolio includes solutions to improve project execution, direct and indirect manufacturing supply chain optimization programs, lighting and renewables advisory services, and digital and automation solutions to improve safety and productivity.
Communications & Security Solutions
The CSS segment serves customers in over 50 countries and is a global leader in data center, network infrastructure and security solutions. CSS sells directly to end-users or through an extensive network of channel partners, including data communications contractors, security and network integrators, professional audio/visual integrators, and systems integrators. Beyond its core portfolio, CSS provides a wide range of professional A/V, safety, facilities, and energy management solutions. The full CSS product portfolio is frequently coupled with services designed to enhance efficiency and productivity across all customer segments globally. These services include data center services, advisory, installation enhancement, project deployment, supply chain solutions, and management platforms.
Utility & Broadband Solutions
The UBS segment serves customers primarily in the U.S. and Canada and provides products and services to investor owned utilities, electric power cooperatives and municipalities, as well as global service providers, wireless providers, broadband operators and the contractors that service these customers. The products sold include wire and cable, transformers, transmission and distribution hardware, switches, protective devices, connectors, lighting, conduit, fiber and power cable, connectivity products, pole line hardware, racks, cabinets, safety and MRO products, and point-to-point wireless devices. The UBS segment also offers a complete set of service solutions to improve customer supply chain efficiencies.

About Segments Disclosures
Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.
Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
