IES (Integrated Electrical Services) primarily operates on a business-to-business (B2B) model, providing specialized electrical and communications contracting services across the commercial, industrial, residential, and infrastructure markets throughout the United States. According to its annual reports, IES serves a diverse customer base, and no single customer has represented 10% or more of its consolidated revenue in recent fiscal years.

• General Contractors: IES subsidiaries frequently work as subcontractors for general contractors on large-scale construction projects. They provide essential electrical and communications infrastructure installations for new commercial buildings, industrial facilities, public works, and other significant developments.
• Commercial and Industrial Companies / Property Owners: This broad category encompasses direct clients such as businesses and property owners who contract IES for their specific electrical and communication infrastructure needs. This includes services for offices, retail establishments, manufacturing plants, data centers, educational institutions, healthcare facilities, and other commercial or industrial sites, covering everything from new installations to upgrades and maintenance.
• Public and Private Sector Organizations / Government Agencies: IES engages with governmental entities (federal, state, and local agencies) and other large institutional clients. These projects often involve providing critical electrical and communications services for public infrastructure, utilities, transportation systems, and government facilities.

The increasing adoption of prefabrication and modular construction methods within the residential housing market presents an emerging threat by significantly reducing the scope of traditional on-site electrical and plumbing installation services, which are core to IES's residential segment. This shift in construction methodology, driven by demands for efficiency, cost reduction, and addressing labor shortages, moves work from the construction site to the factory, potentially diminishing demand for conventional specialty contractors reliant on on-site labor.
