What Integrated Electrical Services does

IES Holdings, Inc. (NASDAQ: IESC), doing business as Integrated Electrical Services, is a national provider of electrical, communications, and infrastructure solutions operating through four principal business segments: IES Electrical (commercial and industrial), IES Communications (network technology services), IES Infrastructure Solutions (apparatus services, custom steel fabrication, custom power solutions including generator enclosures and bus systems), and IES Residential (single-family and multi-family electrical, mechanical, and plumbing). The company employs more than 9,000 people across 28 U.S. states and serves end markets including data centers, residential housing, commercial and institutional facilities, industrial and manufacturing, e-commerce, power, and transportation. Its proprietary capabilities include custom steel fabrication (Greiner Industries, 450,000 sq ft facility; Gulf Island Fabrication acquired January 2026), structured cabling, AV, fire and security systems integration, and apparatus rewind/reconditioning through strategically located service centers.

Revenue is generated through three principal streams: project-based design and build contracts (one-time), recurring service and maintenance contracts, and custom product manufacturing/hardware sales (enclosures, bus systems, fabricated steel). Customers include data center operators, national and regional homebuilders, industrial facilities, and commercial/institutional clients. The company operates a national-scale, project-delivery go-to-market supported by investor relations activity and participation in industry events. In Q1 FY2026 (quarter ended December 31, 2025), revenue reached $871 million, up 16% YoY, with the Communications segment surging 51% YoY to $351.9 million on data center demand.

IES Holdings is majority-owned by Tontine Associates, L.L.C., the private investment firm founded by Executive Chairman Jeffrey L. Gendell, who became CEO in October 2020 and transitioned to Executive Chairman on July 1, 2025, when President and COO Matt Simmes was elevated to President and CEO. Under this leadership the company has pursued disciplined, accretive M&A (Bayonet Plumbing 2020, Greiner Industries 2024, Gulf Island Fabrication 2026, Broadwind Abilene 2026) and was added to the S&P MidCap 400 in June 2026.

• Limbach Holdings: Specialty contractor providing HVAC, mechanical, electrical, plumbing, and building controls services for commercial and institutional customers. Smaller-scale direct comparable to IES's commercial mechanical and electrical offerings.

Broad incumbents

• MasTec: Large diversified infrastructure construction company covering communications, oil and gas, power delivery, and clean energy. Comparable through overlapping communications infrastructure and power delivery service lines.
• APi Group: Global provider of safety, specialty, and industrial services including fire suppression and electrical solutions. Comparable through overlapping electrical contracting and life safety/security systems work that mirrors IES Communications and Commercial segments.
