Glancy Prongay & Murray LLP announces that a class action lawsuit has been filed in the United States District Court for the Southern District of Florida on behalf of a class (the "Class") of investors who purchased securities of MasTec, Inc. ("MasTec" or the "Company") (NYSE:MTZ) between August 12, 2014 and March 17, 2015 inclusive (the "Class Period"). Mastec investors have until July 6, 2015 to file a lead plaintiff motion.

MasTec is a leading infrastructure company that operates mainly in North America providing services such as the engineering, building, installation, maintenance, and upgrade of energy, utility, and communications infrastructure.

The Complaint alleges that throughout the Class Period, defendants made materially false and/or misleading statements regarding the Company's financial performance and failed to disclose that (1) certain cost to complete estimates, currently believed to be in the range of zero to $13 million, which were recognized during the company's third quarter of 2014, should have been recognized during the second quarter of 2014; (2) MasTec's internal control over financial reporting was ineffective; and (3) as a result of the foregoing, the Company's public statements were materially false and misleading at all relevant times.

On March 2, 2015, the Company filed a Form 12b-25 to inform the SEC that it would delay the filing of its Annual Report on Form 10-K for the period ended December 31, 2014.

On March 17, 2015, the Company issued a press release after the close of trading announcing another delay in filing its 2014 Form 10-K. Upon this news, shares of MasTec fell $1.88 or over 9.5% on unusually heavy volume, to close at $17.82 on March 18, 2015.
