McCarthy Holdings Acquisitions

McCarthy has historically grown through organic expansion rather than aggressive acquisitions. The company focuses on building internal capabilities and developing long-term client relationships across its target markets.

In 1991, McCarthy purchased SDL, a contracting firm based in Bellevue, Washington. This acquisition expanded McCarthy’s presence in the Pacific Northwest and added capabilities in the semiconductor and technology construction sectors. The firm operated as SDL McCarthy for several years before integrating fully.

The year 2000 brought another strategic move when McCarthy’s Texas division acquired assets and contracts from Concrete Pavers, Inc. of Evansville, Indiana. This gave McCarthy in-house paving capabilities and allowed more competitive bidding on civil transportation projects.

McCarthy created MC Industrial, Inc. in 2005 as a dedicated subsidiary for industrial construction. MC Industrial focuses on heavy industrial projects including refineries, power plants, and manufacturing facilities. The subsidiary completed the BP Whiting Refinery Modernization Project, one of the largest industrial projects in company history.

The most significant recent acquisition came in 2014 when McCarthy Holdings purchased Castle Contracting and its subsidiary CastleGPS. Castle brings sitework, earthwork, and underground utility capabilities to McCarthy’s portfolio. The acquisition also added 3D utility mapping technology powered by GPS, strengthening McCarthy’s design-build offerings. Castle continues to operate as a stand-alone subsidiary under the McCarthy Holdings umbrella.

In 2023, McCarthy made a seed investment in OnSight Technology, a construction technology startup. This investment reflects McCarthy’s ongoing commitment to adopting digital tools that improve project delivery and client outcomes.
