## Company history

IES Holdings was founded in June 1997 as Integrated Electrical Services, with a strategy of consolidating electrical contractors, and completed its initial public offering in January 1998. [18](https://www.sec.gov/Archives/edgar/data/1048268/000095012310113518/c09596e10vk.htm)[19](https://www.getfilings.com/o0000950129-98-005103.html) After financial difficulties, the company filed for Chapter 11 bankruptcy protection in February 2006 and completed its reorganization that May. [20](https://www.sec.gov/Archives/edgar/data/1048268/000095012906005627/h36237exv99w1.htm)

In 2015, IES expanded beyond electrical contracting by acquiring Shanahan Mechanical & Electrical. It changed its name to IES Holdings, Inc. in 2016 and continued broadening its services, including through the 2017 acquisition of NEXT Electric. [21](https://investors.ies-corporate.com/news-releases/news-release-details/integrated-electrical-services-acquires-shanahan-mechanical-and)[22](https://investors.ies-corporate.com/news-releases/news-release-details/integrated-electrical-services-renamed-ies-holdings-inc)[23](https://app.finbar.com/go?id=P73224184)

From 2020 onward, acquisitions extended the business into residential plumbing and HVAC, structural-steel fabrication, engine and generator-set products, and wireless-network infrastructure. [23](https://app.finbar.com/go?id=P73224184)[24](https://app.finbar.com/go?id=P41252029)[25](https://app.finbar.com/go?id=P55346638)[26](https://app.finbar.com/go?id=P29882971) In 2025, Matthew J. Simmes became president and CEO, with Jeffrey Gendell becoming executive chairman; in January 2026, IES acquired Gulf Island Fabrication.
