MasTec Sets $11.50 Price for 12.5 Million Share Follow-On Common Stock Offering

January 24, 2006

Jan 24, 2006 /PRNewswire-FirstCall via COMTEX News Network/ -- MasTec, Inc. (NYSE: MTZ) today announced that it has priced a follow-on offering of 12.5 million shares of common stock at $11.50 per share. MasTec has also granted the underwriters a 30-day option to purchase up to an aggregate of 1.875 million additional shares of common stock at the public offering price, less the underwriting discounts and commissions, solely to cover over-allotments, if any. Morgan Stanley and Friedman Billings Ramsey served as joint book- running managers of the offering. Needham & Company, LLC and Kaufman Bros., L.P. were co-managers.

MasTec estimates that its net proceeds from the offering will be approximately $135.8 million (approximately $156.4 million if the underwriters exercise their over-allotment option in full) after deducting estimated offering expenses, underwriting discounts and commissions. In March 2006 MasTec intends to use at least $75 million and up to $100 million of the net proceeds of the offering to redeem a portion of its 7.75% senior subordinated notes due February 2008. MasTec expects to use the remaining net proceeds for the $18.5 million cash portion of the purchase price for its acquisition of substantially all of the assets of and assumption of certain operating liabilities and contracts of Digital Satellite Services, Inc., working capital, other possible acquisitions of assets and businesses, organic growth and other general corporate purposes. Although MasTec regularly evaluates potential acquisition opportunities, MasTec currently has no definitive agreements to make any other acquisitions.

A written prospectus for the offering may be obtained from Morgan Stanley & Co. Incorporated, Prospectus Department, 180 Varick Street, 2nd Floor, New York, NY 10014, (866) 718-1649 or by e-mail at prospectus@morganstanley.com or from Friedman, Billings, Ramsey & Co., Inc., Attention: Prospectus Department, 1001 19th Street North, Arlington, VA 22209.
