CORAL GABLES, Fla., June 23 /PRNewswire-FirstCall/ -- MasTec, Inc. (NYSE: MTZ) today announced that its underwriters have exercised their entire 15% over-allotment related to the Company's recent senior convertible note offering. MasTec closed the additional $15 million aggregate principal amount of convertible notes on June 22.

The total $115,000,000 aggregate principal amount of senior convertible notes, including the 15% over-allotment, have an interest rate of 4%, with interest paid semi-annually, and mature on June 15, 2014, unless earlier repurchased or converted. Proceeds from the additional $15 million aggregate principal amount of new senior convertible notes, will be used for working capital, possible acquisitions of assets and businesses and for general corporate purposes.

The new senior convertible notes are convertible, under certain circumstances, into shares of MasTec common stock at a conversion rate of 63.4417 shares of common stock per $1,000 principal amount of convertible notes, equivalent to a conversion price of approximately $15.76 per share of common stock, subject to adjustment in certain circumstances.

The transaction enhances MasTec's balance sheet and capital structure. Current liquidity increased by approximately $55 million. Additionally, after the new convertible note transaction, the Company's debt maturities and interest rates are very favorable.
