At its core, WESCO helps customers build, connect, power, and protect critical infrastructure by combining distribution scale with logistics and supply-chain services, supported by substantial digital capabilities. It serves a mix of commercial and industrial businesses, contractors, institutions, telecom providers, and utilities that need dependable access to products and coordinated delivery.
One major operating pillar is Electrical & Electronic Solutions (EES), which supplies a broad range of products and solutions primarily to construction, industrial, and OEM markets. This segment’s portfolio spans electrical equipment and supplies, automation/connected devices, lighting, wire and cable, safety, and MRO products, alongside services aimed at improving project execution and manufacturing supply-chain efficiency.
A second pillar is Communications & Security Solutions (CSS), focused on network infrastructure and security markets that support connectivity in commercial buildings and data centers. Its scope includes cabling and connectivity, racks and cabinets, power and wireless infrastructure, plus security solutions like video surveillance and access control, often bundled with project and deployment services to improve productivity.
The third pillar is Utility & Broadband Solutions (UBS), serving investor-owned utilities, public power entities, broadband operators, and contractors with products and services tied to grid and network buildouts, while also including an integrated supply business supporting large end-users’ MRO needs. WESCO’s acquisition of Anixter expanded its capabilities across these areas, and the company has continued using the Anixter name as part of its brand strategy.
