For Immediate Release

MasTec Announces Fourth Quarter and Annual Results, Amended and Expanded Credit Facility and Issues 2017 Guidance

• Record Q4 and Annual 2016 Revenue Increased Organically 31% and 22%, respectively, with Annual Revenue at $5.1 Billion

• Q4 and Annual 2016 Significantly Improved Financial Results, with GAAP Net Income of $55.9 Million and $134.0 Million, Respectively

• Q4 and Annual 2016 Adjusted EBITDA of $154 Million and $477 Million, $22 Million Above Forecast

Coral Gables, FL (February 23, 2017) — MasTec, Inc. (NYSE: MTZ) today announced better than expected 2016 fourth quarter and full year financial results, and issued its initial 2017 guidance range.

• Fourth quarter 2016 revenue was $1.34 billion, a 31% increase compared with $1.03 billion for the same period last year. GAAP net income was $55.9 million, or $0.66 per diluted share, compared to a net loss of $76.9 million, or $0.96 per diluted share, in the fourth quarter of 2015. The net loss in the 2015 period was primarily caused by a non-cash goodwill and intangible asset impairment related to the Company’s western Canadian Oil and Gas operations.

• Fourth quarter 2016 adjusted net income, a non-GAAP measure, was $60.0 million compared to $16.8 million in the same period of the prior year. Fourth quarter 2016 adjusted diluted earnings per share, a non-GAAP measure, was $0.70, compared to $0.21 in the fourth quarter of 2015, and exceeded the company’s previously announced 2016 fourth quarter guidance expectation by $0.16 per adjusted diluted share.

• Fourth quarter 2016 adjusted EBITDA, also a non-GAAP measure, was $154 million, an 87% increase compared to $82 million in the same period in 2015.

• 18-month backlog as of December 31, 2016 was $5.4 billion, including record Oil & Gas segment backlog of $2.2 billion.

The Company also reported:

• For the year ended December 31, 2016, revenue was $5.1 billion, a 22% increase compared with $4.2 billion for the prior year. GAAP net income was $134.0 million, or $1.61 per diluted share, compared to a net loss of $79.7 million, or $0.98 per diluted share, in 2015.

• Full year 2016 adjusted net income, a non-GAAP measure, was $157.7 million compared to $51.4 million for 2015. Full year 2016 adjusted diluted earnings per share, a non-GAAP measure, was $1.90, compared to $0.64 in 2015, and exceeded the company’s previously announced 2016 full year guidance expectation by $0.17 per adjusted diluted share.

• Full year 2016 adjusted EBITDA, also a non-GAAP measure, was $477 million, a 55% increase compared to $308 million in 2015.

• During the year ended December 31, 2016, the Company significantly improved its leverage metrics, reducing its book leverage ratio, as noted in the attached schedule, from 3.3 at the beginning of the year to 2.1 as of December 31, 2016.

Adjusted net income, adjusted diluted earnings per share, adjusted EBITDA and book leverage ratio, which are all non-GAAP measures, exclude certain items which are detailed and reconciled to the most comparable GAAP-reported measures in the attached Supplemental Disclosures and Reconciliation of Non-GAAP Disclosures.

Jose Mas, MasTec’s Chief Executive Officer, commented, “We exceeded our fourth quarter expectations, driven primarily by improved productivity in our Oil & Gas segment. We also signed pipeline contracts approximating $1.7 billion during the quarter, ending the year, as expected, with record Oil & Gas segment backlog. We expect record results for our Oil & Gas segment in 2017 and continue to have clear visibility to continued opportunities in this segment for several years.”

Mr. Mas continued, “I want to thank the men and women of MasTec for their dedicated efforts during 2016 and look forward to a great 2017 and beyond.”

The company also announced that it has entered into an amended and restated credit facility with a syndicate of lenders led by Bank of America, N.A. and SunTrust Bank, which increased the capacity under the senior secured credit facility by over $250 million to $1.5 billion and extended the maturity date of the facility to February 2022. The amended credit facility also contains more favorable terms and provides additional flexibility for borrowings in foreign currencies.

George Pita, MasTec’s Executive Vice President and Chief Financial Officer noted, “We had strong financial performance and working capital management during 2016, enabling us to significantly improve our leverage ratios, despite the working capital usage associated with over $900 million in organic revenue growth during the year. We appreciate the continued support and confidence of the financial institutions involved in our credit facility. The amended facility further strengthens our capital structure and liquidity, allowing us full financial flexibility to take advantage of the significant growth opportunities in the markets we serve.”

Based on the information available today, the Company is providing both first quarter and full year 2017 guidance. The Company currently estimates 2017 revenue will increase 7% to approximately $5.5 billion. 2017 full year GAAP net income is expected to approximate $188 million, with adjusted EBITDA, a non-GAAP measure, expected to increase 15% to $550 million. 2017 full year GAAP diluted earnings per share are expected to be $2.24, a 39% increase over 2016, with adjusted diluted earnings per share, a non-GAAP measure, expected to be $2.35, a 24% increase over 2016.

For the first quarter of 2017, the Company expects revenue of approximately $1.05 billion. First quarter 2017 GAAP net income is expected to approximate $40 million, with adjusted EBITDA, a non-GAAP measure, expected to increase 132% and approximate $125 million. First quarter 2017 GAAP diluted earnings per share are expected to approximate $0.48 with adjusted diluted earnings per share, a non-GAAP measure, expected to approximate $0.51. First quarter 2017 guidance reflects expected improved Oil & Gas segment performance due to higher revenues and efficiencies, as well as improvement in the Electrical Transmission segment results.

Management will hold a conference call to discuss these results on Friday, February 24, 2017 at 9:00 a.m. Eastern time. The call-in number for the conference call is (719) 457-2601 and the replay number is (719) 457-0820, with a pass code of 6638861. 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.
