CORAL GABLES, Fla., Feb. 29, 2024 /PRNewswire/ -- MasTec, Inc. (NYSE: MTZ) today announced 2023 fourth quarter and full year financial results and issued its initial 2024 guidance expectation.

For the Fourth Quarter:

Fourth quarter 2023 revenue was up 9.0% to $3.3 billion, compared to $3.0 billion for the fourth quarter of 2022. GAAP net income was $1.2 million, or $0.01 per diluted share, compared to $3.4 million, or $0.04 per diluted share, in the fourth quarter of 2022.

Fourth quarter 2023 adjusted net income and adjusted diluted earnings per share, both non-GAAP measures, were $52.0 million and $0.66, respectively, as compared to $80.0 million and $1.03, respectively, in the fourth quarter of 2022.

Fourth quarter 2023 adjusted EBITDA, also a non-GAAP measure, was $231.4 million, compared to $257.9 million in the fourth quarter of 2022. Fourth quarter 2023 adjusted EBITDA margin rate was 7.1% of revenue.

18-month backlog as of December 31, 2023 was $12.4 billion, with sequential growth in each segment, excluding Oil & Gas, totaling $373 million. The Oil & Gas backlog decrease was primarily related to the expected 2024 completion of a large natural gas pipeline project.

Fourth quarter Cash Flow from Operations was very strong at almost $500 million, enabling significant net debt reduction. Net debt leverage ratio improved significantly from 3.4 times at the end of the third quarter to 2.9 times at yearend.

For the Full Year:

For the year ended December 31, 2023, revenue was up 23% to $12.0 billion, compared to $9.8 billion for the prior year. GAAP net loss was $47.3 million, or a loss of $0.64 per diluted share, compared to net income of $33.9 million, or earnings of $0.42 per diluted share in 2022.

Full year 2023 adjusted net income and adjusted diluted earnings per share, both non-GAAP measures, were $156.7 million and $1.97, respectively, compared to $234.8 million and $3.05, respectively, during 2022.

Full year 2023 adjusted EBITDA, also a non-GAAP measure, was up 10% to $860.3 million, compared to $780.6 million in 2022. Full year 2023 adjusted EBITDA margin rate was 7.2% compared to 8.0% last year.

Adjusted net income, adjusted diluted earnings per share, adjusted EBITDA and net debt, which are all non-GAAP measures, exclude certain items that 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, "Fourth quarter results were in line with our expectations after a challenging 2023. We look forward to the opportunities we have this year and expect to deliver record levels of revenue and adjusted EBITDA in 2024. Demand is very strong for our services, and I expect 2024 will position us to deliver double digit revenue and earnings growth in 2025 and beyond."

Mr. Mas continued, "I'd once again like to thank the 34,000 men and women of MasTec who work every day to build, maintain, and improve the nation's communications, transportation, energy, and industrial infrastructure. It is hard work, and it's because of them that we have great long-term opportunities."

Paul DiMarco, MasTec's Executive Vice President, and Chief Financial Officer, noted, "I'm pleased that we were able to finish 2023 with strong cash flow generation of almost $500 million in Q4, significantly exceeding our prior expectations. DSO, at 74 days was at its lowest level since mid-2017. We are keenly focused on capital allocation to ensure we are generating appropriate returns on the capital we deploy. We will continue to focus on improving the tools and processes we utilize to measure and optimize our performance, and to capitalize on the robust demand environment provided by our end markets."

Based on the information available today, the Company is providing both first quarter and full year 2024 guidance. The Company currently expects full year 2024 revenue will approximate $12.5 billion, a record level. 2024 full year GAAP net income and diluted earnings per share are expected to approximate $105 million and $1.04, respectively. Full year 2024 adjusted EBITDA is expected to approximate $955 million, representing 7.6% of revenue, and adjusted diluted earnings per share is expected to approximate $2.69.

For the first quarter of 2024, the Company expects revenue of approximately $2.6 billion. First quarter 2024 GAAP net loss is expected to approximate $61 million, with GAAP diluted loss per share expected to approximate $0.88. First quarter 2024 adjusted EBITDA is expected to approximate $130 million or 5.0% of revenue, with adjusted diluted loss per share expected to approximate $0.48. The projected loss in the first quarter is the result of a normal seasonally slow quarter, project delays and project start-up costs.

Management will hold a conference call to discuss these results on Friday, March 1, 2024 at 9:00 a.m. Eastern Time. The call-in number for the conference call is (856) 344-9221 or (888) 256-1007 with a pass code of 4316181.

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.

MasTec uses EBITDA and Adjusted EBITDA, as well as Adjusted Net Income, Adjusted Diluted Earnings Per Share and net debt, to evaluate our performance, both internally and as compared with its peers, because these measures exclude certain items that may not be indicative of its core operating results, as well as items that can vary widely across different industries or among companies within the same industry. MasTec believes that these adjusted measures provide a baseline for analyzing trends in its underlying business. MasTec believes that these non-U.S. GAAP financial measures provide meaningful information and help investors understand its financial results and assess its prospects for future performance. Because non-U.S. GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-U.S. GAAP financial measures having the same or similar names. These financial measures should not be considered in isolation from, as substitutes for, or alternative measures of, reported net income or diluted earnings per share or total debt, and should be viewed in conjunction with the most comparable U.S. GAAP financial measures and the provided reconciliations thereto. MasTec believes these non-U.S. GAAP financial measures, when viewed together with its U.S. GAAP results and related reconciliations, provide a more complete understanding of its business. Investors are strongly encouraged to review the company's consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.
