Terms of the transaction were not disclosed. Founded in 1981 and headquartered in Pasadena, TX, Colt provides mission-critical services that help customers keep critical assets on-line, minimize unplanned downtime, and extend asset life. The Company’s capabilities include on-line leak repair, hot tapping, line stopping, line intervention, and field machining, supported by in-house engineering and manufacturing capabilities. Colt serves a diversified base of blue-chip industrial, energy, utility, and municipal customers across the U.S. Under Capstreet’s ownership, Colt expanded significantly both organically and through acquisitions, transforming from a regional leak repair specialist into a national platform with locations across the U.S. Capstreet supported four add-on acquisitions — Plant Services, Inc., RJ Stacey, Garrison Enterprise Inc., and Watertap, Inc. — that expanded Colt’s geographic reach, service capabilities, and customer base. “Colt is the kind of business Capstreet is built to partner with — a founder-owned and operated company with deep technical expertise, a strong safety culture, and a mission-critical role in its customers’ operations,” said Neil Kallmeyer, Managing Partner at Capstreet. “Working alongside Jason and his team, we applied our Capvalue Framework® to invest in the people, systems, and capabilities needed to support Colt’s growth, while executing a disciplined acquisition strategy that helped transform the Company from a regional provider into a national platform. The strength of the business today is a testament to Jason and the entire Colt team and what we were able to accomplish together.” “Capstreet has been an exceptional partner to Colt, supporting our team and investing alongside us as we have grown and strengthened the business,” said Jason Box, CEO of The Colt Group. “We are incredibly proud of what we have accomplished together and grateful for Capstreet’s partnership. We look forward to building on that momentum as we begin our next chapter with LLCP.” “Jason and the Colt team have done an outstanding job building the business and positioning it for continued success,” added Chas Richard, Principal at Capstreet. “We congratulate the entire team and look forward to watching Colt continue to grow.” Houlihan Lokey, Inc. served as financial advisor and Willkie Farr & Gallagher LLP served as legal counsel to Colt and Capstreet. Harris Williams and Kirkland & Ellis LLP advised LLCP. **About The Colt Group** Founded in 1981, Colt provides on-line leak sealing, repair, and prevention solutions, including design, engineering, manufacturing, and installation, to a diverse base of blue-chip industrial clients.
