For Immediate Release

MasTec Acquires Canadian Energy Infrastructure Company Fabcor

Coral Gables, FL (April 26, 2011) — MasTec, Inc. (NYSE: MTZ) today announced that it has acquired Fabcor TargetCo, Ltd., and its subsidiaries (“Fabcor”), a Canadian pipeline and facility construction services company with offices in Grand Prairie, Alberta and Dawson Creek, British Columbia, Canada. Fabcor’s pipeline and facility construction services to the oil and gas industry include: new pipeline construction; pipeline modification and replacement services; well-site and compressor station construction services; and gas plant modification and plant commissioning support services.

MasTec acquired all of the issued and outstanding shares of Fabcor for approximately $21.1 million in cash, the assumption of $8.8 million in debt which was subsequently paid off, plus a five-year contingent earnout. Fabcor had a strong balance sheet at closing, with $26.3 million in tangible net worth, $15 million of which was related to pipeline construction equipment. Fabcor has worked for most major oil and gas companies in Canada, including Murphy Oil Corporation, Encana, and Quicksilver. Fabcor was recently awarded a contract to construct a 100 MMcf/d natural gas processing plant in British Columbia.

MasTec anticipates significant opportunities for energy infrastructure work in Canada during the coming years and that Fabcor will provide MasTec the platform it needs to provide those services in a variety of areas. While Fabcor’s initial focus will be on pipeline and facility related projects, MasTec plans to leverage this investment and participate in other areas of the Canadian energy infrastructure build-out.

Jose Mas, MasTec’s Chief Executive Officer, commented, “We are very excited about the Fabcor acquisition. Its strong management team and dedicated workforce will provide MasTec with access to the dynamic Canadian energy markets, which we believe will show significant profitable growth in coming years.”

Mr. Mas continued, “Our acquisition program is now focused on smaller, strategic companies that can enhance our current geographic or client reach. Fabcor fits this profile as it provides us with an immediate presence in the Canadian market, allowing us to serve new as well as existing MasTec customers. We believe that Fabcor is the right fit for our business model, as it will create opportunities and expose MasTec to a very large infrastructure market adjacent to the markets we currently serve.”

A financial and operational update of the transaction, as well as financial projections affecting 2011 guidance, will be given in conjunction with MasTec’s first quarter earnings call on May 5^th at 9:00 a.m. Eastern time.
