Adjusted EBITDA financial
"GAAP Net Income of $69.7 million and Adjusted EBITDA of $283.6 million, both first quarter records"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
18-month backlog financial
"Record 18-month backlog as of March 31, 2026 of $20.3 billion increased $4.4 billion year-over-year"
The 18-month backlog is the total value of confirmed orders or contracted work that a company expects to deliver over the next eighteen months. Think of it as a to‑do list stretching a year and a half ahead: it shows revenue that is already lined up and gives investors a sense of future sales, production load and cash flow visibility. A large backlog can indicate strong demand but also raises questions about execution risk and capacity to fulfill orders on time.
free cash flow financial
"Free cash flow | $ | 11.9 | | | $ | 45.0 | | |"
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.
non-controlling interests financial
"Net income attributable to non-controlling interests | 8,823 | | | 2,424 |"
An ownership stake in a subsidiary held by outside shareholders rather than the parent company, representing the portion of that subsidiary’s assets and profits the parent does not control. For investors, it shows what part of consolidated earnings and equity belongs to others — like a roommate who owns part of a house — which affects how much value and profit per share are truly attributable to the parent company’s shareholders.
Infrastructure Investment and Jobs Act regulatory
"changes to the amounts provided for under the Infrastructure Investment and Jobs Act and/or Inflation Reduction Act"
A major federal law that authorizes large-scale public spending on roads, bridges, public transit, water systems, broadband, electric grid upgrades and other core physical systems. For investors it matters because the law directs predictable government money into specific industries, creating new contracts, steady demand and potential long-term revenue for companies involved—like a government checkbook funding repairs and upgrades to the infrastructure businesses and communities rely on.
Adjusted diluted earnings per share financial
"Adjusted diluted earnings per share | $ | 1.39 | | | $ | 0.51"
Adjusted diluted earnings per share is the company’s net profit per share after accounting for potential extra shares (from options or convertible securities) and removing one‑time or unusual items so the number reflects ongoing business results. Think of it like timing a runner’s steady pace after excluding a few unexpected stops; it gives investors a clearer view of sustainable profit available to each share. Investors use it to compare companies and judge underlying profitability and valuation without short‑term distortions.
Revenue $3.83B +34.5% YoY
GAAP diluted EPS $0.77 +516.5% YoY
Adjusted diluted EPS $1.39 +174.1% YoY

Guidance

For full-year 2026, MasTec guides to $17.5B revenue, $1.5B Adjusted EBITDA, GAAP diluted EPS of $6.77 and adjusted diluted EPS of $8.79, implying approximately 22% revenue and 30% Adjusted EBITDA growth versus 2025.

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.”

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.
