Coral Gables, FL, October 30, 2025 - MasTec, Inc. (NYSE: MTZ) today announced third quarter 2025 financial results and updated full year 2025 financial guidance.

"We are pleased that third quarter financial performance posted strong double-digit year-over-year growth across both revenue and profit metrics while also exceeding guidance in all respects as MasTec continues to execute on notably strong customer demand across all end-markets we serve," said Jose Mas, MasTec's Chief Executive Officer. "Our reported 22% revenue growth, including double-digit increases from all operating segments, underscores the breadth and depth of the strong demand that MasTec is seeing across our energy, power and infrastructure markets. Despite limited emergency restoration services as compared to prior year within Power Delivery, we exceeded third quarter guidance for consolidated revenue and profit metrics while growing our 18-month backlog with solid new bookings." Mr. Mas added, "Our strong third quarter performance is due in large part to the efforts of our many MasTec operating teammates and their clear focus on delivering customer value every day on the job site. Thanks to all of you!"

"MasTec reported impressive revenue growth across all operating segments for the third quarter and we continue to target double-digit growth in both revenue and Adjusted EBITDA for the full year. For the full year 2025, our guidance assumes strong 14% growth in revenue and 13% growth in Adjusted EBITDA versus the prior year, and implied growth of 9% for revenue and nearly 20% growth in Adjusted EBITDA for the fourth quarter. This guidance is inclusive of anticipated permit-driven impacts on our Greenlink project within Power Delivery, thus underscoring MasTec's overall robust growth performance, driven by ongoing strong operating execution and solid leverage realized on the broad-based market opportunities we have seen this year and expect to continue," said Paul DiMarco, MasTec's Chief Financial Officer. "In addition to strong operating execution, our strong balance sheet offers ample flexibility to pursue a disciplined, returns focused capital allocation strategy to enhance shareholder value."

(a)Recast to reflect first quarter of 2025 segment changes.

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, Adjusted EBITDA, EBITDA Margin and Adjusted EBITDA Margin, as well as Adjusted Net Income (Loss), Adjusted Diluted Earnings (Loss) Per Share, Net Debt and Free Cash Flow, 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 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, net income as a percentage of revenue or total debt or net cash provided by operating activities, 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 MasTec's consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.
