MasTec Settles Class Action Lawsuits Without Additional Costs

April 13, 2006

CORAL GABLES, Fla., April 13 /PRNewswire-FirstCall/ -- MasTec, Inc. (NYSE: MTZ) today announced that it has settled several complaints for purported securities class actions, which were filed against the Company and certain of its officers in the second quarter of 2004. These complaints were settled without payment to the plaintiffs by MasTec. While the Company believes it would have been successful in defense of these actions, management concluded that entering into the settlement was the prudent course of action, given the low amount of the settlement, the inherent risk and uncertainty of legal proceedings, and the substantial time and expense required to defend these cases. Additional details on the settlement can be found in the Company's recent filings with the SEC.

Mr. Austin J. Shanfelter, MasTec's President and Chief Executive Officer, noted, "This distraction is now behind us and the settlement will enable us to focus even more intently on increasing shareholder value by improving the business, which continues to perform as expected."
