ITEM 7.01 Regulation FD Disclosure

On November 16, 2010, MasTec, Inc., a Florida corporation (the “Company” or “MasTec”) issued a press release announcing its acquisition of a minority investment in EC Source Services, LLC, a Nevada limited liability company (“EC Source”), as well as the Merger Option (as defined below). A copy of the Company’s press release is furnished as Exhibit 99.1 to this report on Form 8-K. The information contained in this Item 7.01 of this current report on Form 8-K, including Exhibit 99.1, shall not be deemed “filed” with the Securities and Exchange Commission nor incorporated by reference in any registration statement filed by the Company under the Securities Act of 1933, as amended.

ITEM 8.01 Other Events

On November 16, 2010, MasTec entered into a membership interest purchase agreement pursuant to which for $10 million it purchased a 33% interest in EC Source and acquired a two-year option (the “Merger Option”) that grants MasTec the right, but not the obligation, to acquire EC Source via merger (the “EC Source Acquisition”) pursuant to the terms of an Agreement and Plan of Merger that was entered into on November 16, 2010 by and among MasTec, EC Source, certain wholly owned subsidiaries of MasTec and the members of EC Source (the “Merger Agreement”). MasTec’s $10 million investment will be utilized by EC Source to support working capital and make equipment purchase as necessary to meet demands of its existing and future projects.

Pursuant to the Merger Option and Merger Agreement, if MasTec, in its sole discretion, exercises its option to close the EC Source Acquisition it will be required to pay the other EC Source equity holders 5,153,846 shares of MasTec common stock, par value $0.10 (the “MasTec Shares”), subject to certain purchase price adjustments, and a five-year earn-out, payable in either MasTec Shares or cash at MasTec’s election, based on EC Source’s EBITDA generally equal to 20% of the excess, if any, of EC Source’s annual EBITDA in excess of $15 million. The Merger Agreement provides that the MasTec Shares shall be subject to transfer restrictions which shall lapse 25% on the first anniversary of the closing of the EC Source Acquisition, an additional 25% on the second anniversary of the closing of the EC Source Acquisition and the remaining 50% on the third anniversary of the closing of the EC Source Acquisition.

Should MasTec exercise its Merger Option, the consummation of the EC Source Acquisition will be subject to certain conditions, including, among others, the termination or expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other customary closing conditions. MasTec anticipates making its antitrust filings in the near future. Either MasTec or the EC Source members may terminate the Merger Agreement if MasTec has exercised the Merger Option but the closing of the EC Source Acquisition has not occurred within six months of that exercise or if MasTec has not exercised the Merger Option within two years of entry into the Merger Agreement.
