Summary
GreenArrow, backed by private equity firm CAI Capital, has acquired MSL Electric in an add-on transaction aimed at expanding its footprint in Southern California's electrical contracting market. MSL Electric, founded in 2002 and headquartered in Anaheim, California, operates as a union electrical contractor with established relationships among municipal, county, and state agencies across four Southern California counties.

The target company's core business centers on traffic signal infrastructure, intelligent transportation systems (ITS), and municipal lighting projects—mission-critical services for government infrastructure maintenance and upgrades. As a union shop, MSL Electric brings established labor relationships and compliance frameworks that are typically valuable in public-sector contracting environments where union labor requirements are prevalent.

The transaction reflects a consolidation strategy common in the electrical contracting sector, where platform companies acquire regional competitors to achieve scale, operational efficiencies, and geographic diversification. For CAI Capital's portfolio, the acquisition allows GreenArrow to vertically integrate complementary service lines and expand its addressable market within the public infrastructure spending segment, which remains a stable funding source independent of macroeconomic cycles.
