MIAMI, July 31 /PRNewswire-FirstCall/ -- MasTec, Inc. (NYSE: MTZ) today announced that Eric J. Tveter has been named Executive Vice President and Chief Operating Officer of the Company. In this newly created position, he will be responsible for day-to-day operations as well as managing profitable growth of MasTec's telecommunications, broadband, energy and intelligent traffic system operations. Prior to joining MasTec, Mr. Tveter was an executive with Comcast Corporation, Time Warner Communications, Cablevision Systems Corporation's Lightpath business unit, and Metromedia International Group, Inc. where he held various key roles in the industries served by MasTec, most recently as President of Cablevision Lightpath, Inc.

"The creation of a Chief Operating Officer role demonstrates MasTec's commitment and investment in the future," commented Austin Shanfelter, MasTec President and CEO. Eric's association with MasTec is part of our ongoing effort to attract the best and brightest talent available. He has a unique blend of experience in wireline and wireless telecommunications and broadband sectors, which will be a tremendous asset to the Company. Eric also has excellent relationships with many of our customers. Finally, with his track record of success he will identify ways to improve MasTec's leadership position by focusing on operating more efficiently, on gaining profitable market share through brand building, and on customer satisfaction."

Over the last several months, MasTec has been positioning itself as a strong survivor in this challenging environment. MasTec has not only focused on strengthening its experienced leadership team, but has also:

     * Repositioned its customer base to minimize balance sheet risk;
     * Redefined its operational focus to a more stable revenue stream;
     * Increased its liquidity position; and
     * Launched a program to streamline operating and back office processes.

The net result of these proactive steps has been to both stabilize MasTec's business model and position MasTec to increase its market penetration. The Company believes that significant opportunities exist for revenue growth in both the short and long terms. The expected growth should come from both internal and external opportunities and we believe that customers will want to align with strong service providers. In order to be positioned to acquire new business opportunities, MasTec has been selective in downsizing its operations relative to current demand. In this difficult environment, MasTec is making the investments in the future that the Company believes will be necessary for sustained and profitable growth.
