For Immediate Release

MasTec Announces Second Quarter Results

• Q2 Revenue of $1.07 Billion

• Q2 Continuing Operations Adjusted EBITDA of $71 Million

• Q2 Continuing Operations Adjusted Diluted EPS of $0.10

• Issues Guidance for the remainder of 2015

Coral Gables, FL (August 17, 2015) — MasTec, Inc. (NYSE: MTZ) today announced 2015 second quarter financial results and updated its guidance for the balance of the year.

Second quarter 2015 revenue decreased 3.7% to $1.07 billion from $1.1 billion in the prior year quarter. The quarterly revenue change was primarily composed of revenue declines in the Electrical Transmission and Communications segments, partially offset by revenue increases in the Oil & Gas and Power Generation & Industrial segments. Second quarter 2015 net loss from continuing operations was $3.8 million, or $0.05 per diluted share, compared to net income from continuing operations of $33.7 million, or $0.39 per diluted share, for the second quarter of 2014. Second quarter 2015 results include approximately $0.14 per diluted share for non-operating and non-core charges not included in prior year results, composed primarily of WesTower acquisition integration costs, Audit Committee investigation related costs and the nonrecurring impact of an income tax law change in Alberta, Canada.

Second quarter 2015 adjusted net income from continuing operations, a non-GAAP measure, was $8.1 million compared to $36.4 million in 2014. Second quarter 2015 continuing operations adjusted diluted earnings per share, a non-GAAP measure, was $0.10, compared to $0.42 last year. Second quarter 2015 continuing operations adjusted EBITDA, also a non-GAAP measure, was $71.0 million compared to $108.4 million in 2014.

Adjusted net income from continuing operations, continuing operations adjusted diluted earnings per share and continuing operations adjusted EBITDA, non-GAAP measures, exclude, as applicable, WesTower acquisition integration costs, Audit Committee investigation related costs, losses in a non-controlled joint venture, the non-recurring impact of income tax law changes in Alberta, Canada, and non-cash stock-based compensation expense. Reconciliations of these and other non-GAAP measures to GAAP-reported measures are attached.

Jose R. Mas, MasTec’s Chief Executive Officer, commented, “In the second quarter our business was challenged by the adverse impact of rain and flooding across multiple segments, as well as significant disruptions within our Electrical Transmission segment. While we are not pleased with our current performance, we are very encouraged by the business outlook in multiple segments, especially in Oil & Gas, Wireless and Fiber network upgrades.”

George Pita, MasTec’s Executive Vice President and CFO, added, “We are pleased to resume a normal financial reporting schedule, and want to thank our dedicated staff who worked tirelessly during this difficult and disruptive period. The integrity of our corporate governance and financial reporting is of paramount importance to us and we are working to improve our control processes to correct the issues that gave rise to the previously reported interim period 2014 adjustments. While we are disappointed that these adjustments were necessary, we are very pleased that, as initially expected, they did not materially affect our full year 2014 results.”

The Company currently estimates fiscal year 2015 revenue of $4.2 to $4.3 billion. 2015 continuing operations adjusted EBITDA, a non-GAAP measure, is estimated at $325 to $340 million, with continuing operations adjusted diluted earnings per share, a non–GAAP measure, at $0.73 to $0.83.

For the third quarter of 2015, the Company expects revenue of $1.1 to $1.2 billion. Third quarter 2015 continuing operations adjusted EBITDA, a non-GAAP measure, is estimated between $100 to $108 million, with continuing operations adjusted diluted earnings per share, a non-GAAP measure, estimated between $0.31 to $0.37.

Reconciliations of these and other non-GAAP measures to GAAP-reported measures are attached.

Management will hold a conference call to discuss these results on Tuesday, August 18, 2015 at 9:00 a.m. Eastern time. The call-in number for the conference call is (913) 312-0416 and the replay number is (719) 457-0820, with a pass code of 3722826. The replay will be available for 30 days. Additionally, the call will be broadcast live over the Internet and can be accessed and replayed through the Investors section of the Company’s website at www.mastec.com.
