Warren Equity Announces Acquisition of ADB Companies and Add-On of ETAK Systems

SAINT LOUIS, April 27, 2021-- Warren Equity Partners (“Warren Equity”), a lower middle market private equity firm, is pleased to announce the acquisition of ADB Companies, LLC, and its affiliates (“ADB” or the “Company”) from the Keeley Companies. ADB, based in St. Louis, Missouri, is a leading turnkey provider of telecommunication and utility infrastructure solutions in the United States. Rusty Keeley, CEO of the Keeley Companies, and Chad Johnson, CEO of ADB, will maintain significant equity stakes in the Company. Mr. Keeley and Mr. Johnson will continue as members of the Company’s Board of Directors, and Mr. Johnson will remain CEO of the Company. Financial terms of the transaction were not disclosed.

“We are very excited to partner with Rusty, Chad, and the ADB team. The Company has a fantastic culture and a successful track record focused on safety, quality, and customer service,” said Scott Bruckmann, Partner at Warren Equity. “We believe ADB is well-positioned to serve the growing demand for network capacity and reliability to support increased use of connected devices and data consumption.”

ADB Companies is a national, end-to-end provider of infrastructure services to install, maintain, and operate telecommunication and power infrastructure, including fiber-optic cable networks, wireless cell towers and equipment, power lines, and in-building hardware and technology. These services are critical to support an industry in constant need for improvement, upgrades, and maintenance as smart devices proliferate and data usage increases across the globe. The Company provides these services to the nation’s leading telecommunication, electric utility, technology, and government entities.

“ADB has played a critical role within the Keeley Companies for the last 25 years, so finding the right partner was of utmost importance to my ADB family,” said Rusty Keeley, CEO of Keeley Companies. “We believe that Warren Equity was the perfect fit because of their differentiated sector expertise, track record in scaling similar types of companies, and strong cultural alignment.”

“We have built a best-in-class organization that has tremendous growth potential within the large, mission-critical, and highly fragmented telecommunication and power services industries,” said Chad Johnson, CEO of ADB Companies. “We believe the Company will achieve its strategic growth plan, both organically and through add-on acquisitions, while continuing to provide our customers with high quality service.”

ADB also recently acquired ETAK Systems (“ETAK”), its first add-on acquisition in partnership with Warren Equity. ETAK is a provider of maintenance and ground installation services to wireless and tower owners with a full range of highly technical capabilities and a unique, industry-leading suite of technology-enabled inspection services. ETAK’s core competencies include installation and maintenance for power, HVAC, small cells, and C-RAN, as well as engineering, inspection, and audits for the wireless sector.
