Industrial Electric Mfg. (IEM)

What Industrial Electric Mfg. (IEM) does

Industrial Electric Manufacturing (IEM) is a privately held custom power distribution equipment manufacturer founded in 1950 in Fremont, California, and currently operating as The New IEM LLC under holding company IEM Holdings Group, Inc. The company engineers and manufactures low-voltage switchboards, switchgear, and automatic transfer switches (UL 891, UL 1558, UL 1008), medium-voltage metal-clad and metal-enclosed switchgear up to 38kV including its proprietary VESTA-AR arc-resistant line, and integrated products such as power distribution units (PDUs), remote power panels (RPPs), walk-in enclosures, and bespoke custom assemblies. IEM holds proprietary technology including the magnetically actuated VM1 circuit breaker (rated for 100,000 operations), the IEM XFR-200 transfer switch controller, and IP2X finger-safe panelboard designs, with in-house validation conducted at the IEM Power Lab in Portland, Oregon. The company self-describes as North America's largest independent full-line manufacturer of electrical distribution and integrated control systems.

IEM operates a custom-at-scale business model, with project-based quoting, direct enterprise field sales, and a 14-office field service network across North America supporting installation, commissioning, and lifecycle maintenance. Revenue is generated primarily from one-time custom equipment sales supplemented by professional field services, with pricing conducted through an RFQ process rather than published list pricing. The company serves six primary verticals — Technology & Data Centers (hyperscalers, colocation, AI infrastructure), Healthcare & Life Sciences, Energy & Utilities, Industrial & Manufacturing, Commercial & Real Estate, and Infrastructure & Public Services — with named customers including Amazon, Google, Microsoft, Apple, IBM, AT&T, Chevron, PG&E, Ford, Tesla, Kaiser Permanente, Amgen, NASA, and Lockheed Martin. IEM crosses $1B in annual revenue in 2024, has grown headcount 280% and quadrupled its manufacturing footprint over four years, and currently operates 22+ locations totaling 1.5M+ sq.ft. of production capacity across the USA and Canada under CEO Clayton Such (joined 2011) and a leadership team recruited from Danaher, Eaton, Acuity Brands, Curtiss-Wright, TE Connectivity, and Bain & Company.

Broad incumbents

• ABB: Global electrification leader with deep switchgear, substation and power distribution capabilities, including acquired GE Industrial Solutions assets. Directly comparable to IEM across MV metal-clad switchgear, substations and LV distribution.
• Siemens: Global electrification and digital industries major offering LV/MV switchgear, motor control and integrated power solutions. Overlaps IEM in data center, utility and industrial segments with both catalog and engineered offerings.
• Hubbell Incorporated: Electrical solutions manufacturer with LV distribution, switchgear, panelboards and a meaningful data center exposure through its enclosures and electrical products. A larger incumbent with overlapping product categories but less emphasis on custom-at-scale integration.
• Schneider Electric: Global energy management and automation major (Square D brand in North America) with a comprehensive LV/MV switchgear, switchboard and panelboard portfolio. Directly comparable to IEM's core product lines but at significantly larger scale and global reach.
• Eaton Corporation: Global power management leader with a large switchgear and switchboard portfolio across LV/MV classes. IEM's CRO Sean Goforth started his career at Eaton, underscoring direct product overlap; Eaton is a much larger incumbent offering broader catalog solutions where IEM competes on customization.

Emerging players

• Star Electrical / T&S Power (custom switchgear integrators): Custom switchgear and integrated power solutions providers serving data center, healthcare and industrial customers with engineered LV/MV assemblies. Comparable to IEM's custom-assemblies and integrated products business for sub-hyperscale projects.
• nVent Electric: Electrical connection and protection solutions company expanding into data-center power infrastructure including enclosures, power distribution and liquid cooling adjacencies. Partial overlap with IEM's integrated power and walk-in enclosure offerings for data center customers.

Direct peers

• Vertiv Holdings: Critical digital infrastructure provider with strong data-center power distribution, PDU, switchgear and service overlap. Directly comparable to IEM in the hyperscale data center power distribution unit and integrated power solutions space.
• Powell Industries: Houston-based custom-engineered electrical houses and MV switchgear/integration specialist serving utilities, oil & gas and industrial markets. Closely comparable to IEM's custom-at-scale, project-based MV switchgear and integrated systems model.
