Acquisitions
According to its website, Quanta employs a decentralized acquisition strategy that allows its acquisitions to retain their management, brand and customers. It has over 200 acquired companies employing 62,000 workers.[18] Acquisitions began shortly after the original company was formed. In 1999, the organization acquired 11 companies with total revenues of $150 million(US).[19] In 2000, the firm bought the Utilities Construction Company, TVS Systems, Southeast Pipeline Construction, MC Underground, the Croce Electric Company, and the Eastern Communications Corporation.[20]
In 2007, Quanta bought Infrasource Services for $1.26 billion(US) in an all-stock transaction.[21] In 2009, it purchased Price Gregory, specializing in the building of large-diameter transmission pipelines, for $350 million(US) in a cash and stock deal.[22][23] In 2019, Quanta purchased Hallen Construction, a gas utility contractor serving the northeast, contractors R.R. Cassidy and Florida's Marathon Construction Services for $328 million(US) in cash and $2 million(US) in stock. [24] In 2021 the firm purchased the Blattner Company, a Minnesota-based renewable contracting company, for $2.7 billion(US) in stock and cash, a move that will assist in growing in the rapidly expanding renewable energy resources category. [25][26] Also in 2021, Quanta acquired William E. Groves Construction of Madisonville, Kentucky. [27]
In 2023, the company added RP Construction Services, a solar power contractor.[28] The same year, Quanta purchased Pennsylvania Transformer Technology, designer and builder of transformers, substation units and other electrical power components, for $300 million(US) in a cash and stock transaction. [29] In 2024, the firm bought California-based Cupertino Electric for $1.5 billion(US) in a mostly cash transaction providing Quanta with Cupertino's skilled workers and help the company position itself as an all-purpose power transmission and distribution resource.[30] Cupertino, founded in 1954, was the US’ sixth largest electrical contractor and has installed electrical power in over 20 million sq. ft. of data centers. It was experiencing exponential growth with the onset of artificial intelligence. [31] Cupertino Electric has long been a major contractor in mission-critical construction, subsequently Quanta was ranked No. 1 on ENR’s 2023 Top 600 Specialty Contractors list. Engineering News-Record said the transaction was the “biggest deal of the year” in the electrical construction sector.[32] Following the acquisition, the company continued to execute hyperscale work; a 2025 IBEW Local 332 newsletter reported crews performing electrical installation on an approximately 268,500-square-foot EdgeCore data-center project, underscoring sustained demand tied to AI-driven computing growth.
Also in 2024, the firm acquired the electric power components manufacturer Sherman and Reilly, founded in Chattanooga in 1927.[36] Quanta acquired its first steel mill, Hybar LLC, whose Arkansas plant will be manufacturing steel rebar, used in large energy power projects.[37]
