**MasTec Reports First Quarter 2026 Results and** 

**Increases Full Year 2026 Financial Guidance**

**First Quarter 2026 Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Revenue of $3.8 billion, a first quarter record, increased 34% year-over-year**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Record 18-month backlog as of March 31, 2026 of $20.3 billion increased $4.4 billion year-over-year and $1.4 billion from the prior quarter, led by significant 65% year-over-year growth in Clean Energy and Infrastructure**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Diluted EPS of $0.77 and Adjusted Diluted EPS of $1.39, increased 516% and 174% year-over-year, respectively, and exceeded guidance expectations**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• GAAP Net Income of $69.7 million and Adjusted EBITDA of $283.6 million, both first quarter records, increased by 465% and 73% year-over-year, respectively, and exceeded guidance expectations**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Increased Full Year Diluted EPS guidance to $6.77, a 33% year-over-year increase; Increased Full Year Adjusted Diluted EPS guidance to $8.79, a 34% year-over-year increase**

**Coral Gables, FL, April 30, 2026** — MasTec, Inc. (NYSE: MTZ) today announced first quarter 2026 financial results and increased full year 2026 financial guidance.

"We are pleased to report that first quarter financial performance posted strong double-digit year-over-year growth in both revenue and profitability, while also exceeding guidance in all respects as MasTec continues to execute on very strong customer demand across all of our end-markets," said Jose Mas, MasTec's Chief Executive Officer. "Our reported 34% revenue growth, including double-digit increases from all operating segments, was led by a 91% increase in Pipeline Infrastructure and a 45% increase in Clean Energy and Infrastructure. The strong demand and our operational discipline allowed us to significantly exceed first quarter guidance expectations. Our 18-month backlog included solid new bookings, up $4.4 billion compared to the prior year's first quarter and up $1.4 billion sequentially from year-end." Mr. Mas added, "Our strong first quarter performance is due in large part to the efforts of the thousands of MasTec operating team members and their focus on delivering customer value, safety and improving performance on every job site each and every day. They are the real heroes here, and I appreciate their tireless efforts and professionalism!"

"MasTec continued its trajectory of improved financial performance across all operating segments during the first quarter. Our first quarter performance, well ahead of guidance expectations, enabled us to further increase our expectations for the year. For the full year 2026, our updated guidance assumes strong 22% growth in revenue and 30% growth in Adjusted EBITDA versus the prior year," said Paul DiMarco, MasTec's Chief Financial Officer. "In addition to strong operating execution, our strong balance sheet offers ample flexibility to pursue our disciplined, returns focused capital allocation strategy to enhance shareholder value."

**Revenue:** Revenue increased by 34% in the period including double-digit growth contribution from all segments.

**GAAP Net Income/GAAP Net Income Margin/GAAP Diluted EPS:** The increase was primarily driven by increased year-over-year project volumes.

**Adjusted EBITDA Margin:** The increase was primarily driven by improved efficiencies within the Pipeline Infrastructure and Power Delivery segments, as well as a combination of project mix and improved productivity and efficiencies within the Clean Energy and Infrastructure segment, partially offset by costs to exit certain markets in our install-to-the-home business within the Communications segment.

**Backlog:** Strong 28% year-over-year growth driven most notably by the Clean Energy and Infrastructure segment, which increased 65%, including strong backlog additions in both renewables and infrastructure.

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.

The tables may contain slight summation differences due to rounding.

MasTec uses EBITDA, Adjusted EBITDA, EBITDA Margin and Adjusted EBITDA Margin, as well as Adjusted Net Income, Adjusted Net Income attributable to MasTec, Inc., Adjusted Diluted Earnings 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.

the effect on demand for our services of changes in the amount of capital expenditures by our customers due to, among other things, economic conditions, including potential economic downturns, inflationary issues, tariff effects, the availability and cost of financing, supply chain disruptions, climate-related matters, customer consolidation in the industries we serve and/or the effects of public health matters; activity in the industries we serve and the impact on the expenditure levels of our customers of, among other items, fluctuations in commodity prices, including for fuel and energy sources, fluctuations in the cost of materials, labor, supplies or equipment, and/or supply-related issues that affect availability or cause delays for such items;

our ability to attract and retain qualified personnel, key management and skilled employees, including from acquired businesses, our ability to enforce any noncompetition agreements, and our ability to maintain a workforce based upon current and anticipated workloads; any material changes in estimates for legal costs or case settlements or adverse determinations on any claim, lawsuit or proceeding; the adequacy of our insurance, legal and other reserves; adverse climate and weather events, such as the risk of wildfires, that increase operational and legal risks in certain locations where we perform services, could increase the potential liability and related costs associated with such operations; the highly competitive nature of our industry and the ability of our customers, including our largest customers, to terminate or reduce the amount of work, or in some cases, the prices paid for services, on short or no notice under our contracts, and/or customer disputes related to our performance of services and the resolution of unapproved change orders; the effect of regulatory initiatives, including risks related to and the costs of compliance with existing and potential future sustainability requirements, including with respect to climate-related matters;

our dependence on a limited number of customers and our ability to replace non-recurring projects with new projects; risks associated with potential environmental issues and other hazards from our operations; disputes with, or failures of, our subcontractors to deliver agreed-upon supplies or services in a timely fashion, and the risk of being required to pay our subcontractors even if our customers do not pay us; risks related to our strategic arrangements, including our equity investments; risks associated with volatility of our stock price or any dilution or stock price volatility that shareholders may experience, including as a result of shares we may issue as purchase consideration in connection with acquisitions, or as a result of other stock issuances; our ability to obtain performance and surety bonds; risks associated with operating in or expanding into additional international markets, including risks from increased tariffs, fluctuations in foreign currencies, foreign labor and general business conditions and risks from failure to comply with laws applicable to our foreign activities and/or governmental policy uncertainty;

risks associated with our internal controls over financial reporting; risks related to a small number of our existing shareholders having the ability to influence major corporate decisions, as well as other risks detailed in our filings with the Securities and Exchange Commission. We believe these forward-looking statements are reasonable; however, you should not place undue reliance on any forward-looking statements, which are based on current expectations. Furthermore, forward-looking statements speak only as of the date they are made.
