MasTec, Inc. (MTZ) Stock Price & How to Invest

MasTec (NYSE: MTZ) is a Coral Gables, Florida based engineering and construction firm that builds and maintains large-scale infrastructure across four segments: Communications (wireless and wireline/fiber), Power Delivery (utility transmission and distribution), Pipeline Infrastructure (natural gas installation and maintenance), and Clean Energy and Infrastructure (renewables engineering, construction, and heavy civil). The company works for utilities, telecom carriers, energy operators, and government customers, and grows both organically and through acquisitions such as the roughly $1.65 billion planned Superior Group deal.

The investment picture is a cyclical growth story tied to US infrastructure spending. Revenue reached roughly $14.3 billion in 2025 and demand is accelerating into 2026, driven by grid upgrades, data-center power needs, and renewable buildout, with an 18-month backlog at a record level above $20 billion. That momentum has pushed the stock to a premium valuation, so returns hinge on the company converting backlog into margin-accretive revenue while managing project execution, weather, and customer capital-spending cycles.

MasTec is cyclical and project-based, so revenue and margins can swing with customer capital budgets, permitting delays, weather, and the timing of large contracts. The stock trades at a high earnings multiple (trailing P/E in the 60s), leaving little cushion if growth or margins disappoint. The company carries debt and pursues sizable acquisitions such as Superior Group, adding integration and balance-sheet risk. Fixed-price contracts expose it to cost overruns, and a handful of large customers and projects can concentrate outcomes. Shifts in energy, telecom, or renewable-subsidy policy could also alter demand across its segments.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see MasTec, Inc.'s investor relations page or your broker.

• Revenue (2025 FY): ~$14.3B
• Revenue (TTM): ~$15B
• 2026 revenue guidance: ~$17.5B
• Adjusted diluted EPS (2025): ~$6.55
• 18-month backlog: ~$20.3B
• Market cap: ~$28B

MasTec is a large-cap infrastructure contractor trading at a premium multiple, with a trailing P/E in the low-to-mid 60s reflecting strong expected earnings growth. Management raised 2026 guidance after a record Q1, targeting roughly $17.5 billion in revenue and about $8.79 in adjusted EPS. The valuation prices in continued backlog conversion, so results relative to that growth path matter more than the absolute multiple.

There are three common ways to get MTZ exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so MTZ sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where MTZ fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

MasTec is a levered play on US infrastructure spending, growing fast off a record backlog but priced richly, so the risk sits in execution and the durability of that demand.

Whether MTZ is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is MTZ a buy?, and where the stock could go from here in the MTZ stock forecast.
