Summary
Capstreet, a Houston-based lower middle market private equity firm, announced the sale of The Colt Group to Levine Leichtman Capital Partners (LLCP), a Los Angeles-based middle market PE firm. The transaction closed on September 1, 2026, though deal terms were not disclosed.
The Colt Group, established in 1981 and based in Pasadena, Texas, operates in the specialized industrial services sector, providing on-line leak repair, hot tapping, line stopping, line intervention, and field machining capabilities. The company serves a diversified customer base of blue-chip industrial, energy, utility, and municipal clients throughout the United States. Its core value proposition centers on delivering mission-critical services that help customers maintain asset uptime, minimize unplanned downtime, and extend asset operational life. The company's in-house engineering and manufacturing capabilities differentiate its service offerings.
During Capstreet's holding period, Colt underwent substantial transformation through both organic expansion and add-on acquisition strategy. The platform completed four strategic acquisitions—Plant Services Inc., RJ Stacey, Garrison Enterprise Inc., and Watertap Inc.—that materially expanded geographic footprint, technical service capabilities, and customer diversification. This build-out strategy converted Colt from a regional leak repair specialist into a national platform with operational locations across multiple U.S. markets.
Neil Kallmeyer, Managing Partner at Capstreet, characterized Colt as emblematic of Capstreet's investment thesis, noting the company's founder-operated structure, deep technical expertise, strong safety culture, and mission-critical positioning within customer operations. The sale to LLCP, a middle market PE firm with broader asset base than Capstreet, suggests positioning of Colt for potential further platform consolidation or operational scaling under new ownership.
