For Immediate Release

MasTec Announces Third Quarter 2023 Financial Results and Updates Guidance for the Year

Coral Gables , FL **** (October 31, 2023) — MasTec, Inc. (NYSE: MTZ) today announced 2023 third quarter financial results and updated its full year 2023 guidance expectations. Management has elected to accelerate the timing of its third quarter earnings call now scheduled for Wednesday, November 1^st^, 2023 at 8:00 AM Eastern Time.

Third Quarter 2023 results are as follows:

Record Revenue of $3.26 billion
GAAP Net Income of $15 million
--- ---
Adjusted Net Income of $76 million
--- ---
Adjusted EBITDA of $271 million
--- ---
GAAP Diluted earnings per share of $0.18
--- ---
Adjusted diluted earnings per share of $0.95
--- ---
Cash flow provided by operating activities of $294 million
--- ---
Net debt reduction of $213 million
--- ---
Liquidity of ~$1.16 billion as of September 30, 2023
--- ---

MasTec’s third quarter 2023 results were impacted by continued delays on certain Clean Energy and Infrastructure segment project start dates. Margins in this segment remain pressured by the costs to maintain resources for the anticipated ramp in activity. MasTec also expects a lower level of this segment’s activity in the fourth quarter of 2023, further impacted by the recent announcement by Li-Cycle Holdings Corp., indicating a pause in construction on their Rochester Hub project for which MasTec was providing construction management services on a cost-plus basis. Over the course of 2023 clean energy projects have been delayed due to various factors, including interconnect agreement lead times, supply chain issues, permitting delays and tax equity funding uncertainty. The market and MasTec’s visibility on project timing are improving, as evidenced by approximately $500 million of new contract awards in the segment since the end of the third quarter. MasTec expects significant backlog growth by yearend as projects continue to move towards full notice to proceed.

MasTec’s Oil and Gas segment had a slower than anticipated ramp in construction of the Mountain Valley Pipeline project, as hiring the approximately 3,700 crew members took longer than initial estimates while the project faced ongoing legal challenges in the third quarter. All project activity planned for the fourth quarter is now progressing as scheduled and the Company’s full year $2 billion segment revenue outlook remains intact. MasTec now expects to complete the project in the first half of 2024.

LOGO

Lastly, the Company experienced lower than anticipated revenue in its Communications and Power Delivery segments due to certain customers’ deferral of previously planned activity. These delays were driven by higher financing costs and annual budgetary limitations. MasTec expects the reduced activity to continue through the fourth quarter until annual budget cycles are replenished. Both segments have seen significant awards in the fourth quarter, over $300 million dollars respectively, comprised of territory expansion, new services or new customers, that will flow into backlog at yearend.

In light of these developments, MasTec is also updating its full year guidance. The Company now expects:

Revenue of approximately $12 billion
GAAP Net Loss of approximately $61 million
--- ---
Adjusted Net Income of approximately $140 million
--- ---
Adjusted EBITDA of approximately $850 million
--- ---
GAAP Diluted loss per share of approximately $0.83
--- ---
Adjusted diluted earnings per share of approximately $1.75
--- ---
Cash flow provided by operating activities of approximately $500 million for the second half of 2023 and<br>$400 million for the full year
--- ---

Jose Mas, MasTec’s Chief Executive Officer, commented, “While we are disappointed in our anticipated performance for the second half of 2023, we believe our revised full year guidance fully captures the remaining near-term risks in our business, including the operational challenges IEA has experienced this year. We are keenly focused on providing a clear picture to investors, both near and longer term.”

Mr. Mas continued, “Despite our challenges and the headwinds we’ve faced in 2023, we continue to expect strong, although delayed, demand for our services. Our stated awards post third quarter and expected contract signings through yearend position us to confidently expect mid to high single digit revenue growth in 2024 with modest EBITDA margin expansion. This expectation assumes some continuation of the current economic environment challenges. Our long-term outlook for our business is unchanged and we will work hard to regain the confidence of our stakeholders.”

Paul DiMarco, MasTec’s Executive Vice President and Chief Financial Officer, noted, “Despite the underperformance in our third quarter, we did make progress in cash flow generation, with $294 million dollars of cash flow from operations in the quarter, resulting in net debt reduction of $213 million. We expect this trend to continue in the fourth quarter with net debt reduction slightly lower than the third quarter. While the revised earnings outlook will prevent us from reaching our 2.5x net debt leverage goal by the end of this year, we believe the path to that level is achievable in 2024 with the reasonably obtained 2024 outlook laid out by Jose. We remain very confident in the long-term outlook for our end markets and remain committed to operate the business below 2.5x net debt leverage in support of our investment grade rating.”

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.

Management plans to provide more information on its third quarter earnings call, scheduled for Wednesday, November 1, 2023 at 8:00 AM Eastern Time. The call-in number for the live conference call is (856) 344-9221 or (888) 394-8218, with a confirmation code of 2698200. Additionally, the call will be broadcast live over the Internet and can be accessed, along with any presentation materials, and replayed for 30 days through the Investors section of the Company’s website at www.mastec.com.

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.
