**Coral Gables, FL** (February 23, 2023) — MasTec, Inc. (NYSE: MTZ) today announced 2022 fourth quarter and full year financial results and issued its initial 2023 guidance expectation.

**For the Fourth Quarter:** 

Fourth quarter 2022 revenue was up 66.3% to $3.0 billion, compared to $1.8 billion for the fourth quarter of 2021. GAAP net income was $3.4 million, or $0.04 per diluted share, compared to $76.4 million, or $1.04 per diluted share, in the fourth quarter of 2021.

Fourth quarter 2022 adjusted net income and adjusted diluted earnings per share, both non-GAAP measures, were $80.0 million and $1.03, respectively, as compared to $100.2 million and $1.36, respectively, in the fourth quarter of 2021.

Fourth quarter 2022 adjusted EBITDA, also a non-GAAP measure, was $257.9 million, compared to $220.2 million in the fourth quarter of 2021. Fourth quarter 2022 adjusted EBITDA margin rate was 8.6% of revenue.

18-month backlog as of December 31, 2022 was $13.0 billion, up 31% compared to backlog as of December 31, 2021 of $9.9 billion, and a 16% sequential increase compared to backlog as of September 30, 2022 of $11.2 billion.

As previously announced on October 7, 2022, MasTec completed the acquisition of Infrastructure and Energy Alternatives, Inc., a premier renewables and infrastructure services provider adding approximately $1.1 billion in acquisition financing and assumed debt during the quarter. Post-acquisition, MasTec reduced net debt by approximately $350 million during the fourth quarter.

![LOGO](g443161dsp1.jpg)

**For the Full Year:** 

For the year ended December 31, 2022, revenue was up 23% to $9.8 billion, compared to $8.0 billion for the prior year. GAAP net income was $33.9 million, or $0.42 per diluted share, compared to $330.7 million, or $4.45 per diluted share in 2021.

Full year 2022 adjusted net income and adjusted diluted earnings per share, both non-GAAP measures, were $234.8 million and $3.05, respectively, compared to $420.0 million and $5.65, respectively, during 2021.

Full year 2022 adjusted EBITDA, also a non-GAAP measure, was $780.6 million, compared to $939.1 million in 2021. Full year 2022 adjusted EBITDA margin rate was 8.0% compared to 11.8% last year.

Adjusted net income, adjusted diluted earnings per share, adjusted EBITDA and net debt 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, "As we end 2022, it is important to note the significant end market transformation we have undertaken over the past two years to support the nation's energy transition to sustainable renewable energy sources. In 2020, MasTec recorded $6.3 billion in revenue, and we currently expect to more than double that level and approximate $13 billion in revenue in 2023. We believe that acquisition activity over the last two years has greatly enhanced our scale, expertise and market positioning to meet expected high customer demand growth for renewable power generation, power grid transmission and distribution and civil infrastructure over the next decade. We believe that this opportunity, coupled with continued expected growth in telecommunications infrastructure and expanding demand for traditional and new green pipeline services, positions us with multiple strong long term growth opportunities."

Mr. Mas continued, "I'd like to welcome IEA team members to the MasTec family and once again thank the men and women of MasTec whose dedication to safety and efficient production are a key driving force to our success."

George Pita, MasTec's Executive Vice President and Chief Financial Officer, noted, "Our strong balance sheet has supported our transformational acquisition activity over the past two years. We added approximately $1.1 billion of financing and assumed debt with the fourth quarter IEA acquisition, and as expected, we reduced a substantial amount of this debt with fourth quarter cash flow. We remain committed to maintaining a strong balance sheet and our investment grade rating. We expect to continue to reduce net debt and significantly improve leverage metrics in 2023, due to the combination of improved operating performance and moderated levels of capital and strategic investments."

Based on the information available today, the Company is providing both first quarter and full year 2023 guidance. The Company currently expects full year 2023 revenue will approximate $13.0 billion, a record level. 2023 full year GAAP net income and diluted earnings per share are expected to range between $194 and $212 million and $2.48 and $2.70, respectively. Full year 2023 adjusted EBITDA is expected to range between $1.10 and $1.15 billion, representing between 8.5% and 8.8% of revenue, and adjusted diluted earnings per share is expected to range between $4.64 and $4.91.

For the first quarter of 2023, the Company expects revenue of approximately $2.4 billion. First quarter 2023 GAAP net loss is expected to approximate $86 million, with GAAP diluted loss per share expected to approximate $1.12. First quarter 2023 adjusted EBITDA is expected to approximate $100 million or 4.2% of revenue, with adjusted diluted loss per share expected to approximate $0.57. The projected loss in the first quarter is the result of a variety of factors including a normal seasonally slow quarter, project delays, project start-up costs and integration costs related to recent acquisition activity.

The Company expects to timely file its 2022 Form 10-K on March 1, 2023. With this filing, the Company anticipates it may disclose the identification of a material weakness in its internal controls over financial reporting, primarily related to IT controls at certain 2021 acquired operations undergoing first time internal controls evaluation in 2022. During 2022, the Company has undertaken significant integration, combination, and streamlining activities for transformational 2021 acquisitions. This matter is not expected to result in any changes to the financial results for the year ended December 31, 2022.

Management will hold a conference call to discuss these results on Friday, February 24, 2023 at 9:00 a.m. Eastern Time. The call-in number for the conference call is (856) 344-9221 or (888) 394-8218 with a pass code of 1221549. 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 <u>www.mastec.com</u>. The webcast replay will be available for at least 30 days.

The following tables set forth the financial results for the periods ended December 31, 2022 and 2021:

Backlog is a common measurement used in our industry. Our methodology for determining backlog may not, however, be comparable to the methodologies used by others. Estimated backlog represents the amount of revenue we expect to realize over the next 18 months from future work on uncompleted construction contracts, including new contracts under which work has not begun, as well as revenue from change orders and renewal options. Our estimated backlog also includes amounts under master service and other service agreements and our proportionate share of estimated revenue from proportionately consolidated non-controlled contractual joint ventures. Estimated backlog for work under master service and other service agreements is determined based on historical trends, anticipated seasonal impacts, experience from similar projects and estimates of customer demand based on communications with our customers.
