Communications providers, utilities, power producers and government agencies hire MasTec to build and upgrade the infrastructure they need. Its crews construct networks, generating facilities, power grids and pipelines, then provide maintenance and restoration services. Clean Energy and Infrastructure and Power Delivery together account for most revenue; communications networks and pipeline work are the other substantial businesses.
Customers pay for work delivered, generally through progress payments tied to measurable completion. A substantial share of work comes through multi-year service agreements, usually with fixed-fee work orders; the rest comes from contracts for individual projects. These service agreements do not guarantee work, and customers can often cancel on short or no notice. MasTec has a broad customer base, but a few large customers supply a significant share of revenue. AT&T is an important communications customer.
The business depends on customers committing infrastructure spending and obtaining permits, and on MasTec estimating and executing jobs accurately. On fixed-price work, costs above its estimates can erode earnings. Government funding and tax incentives also influence demand, particularly for clean-energy construction.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Quanta Services competes with MasTec for utility, power-generation, communications and pipeline customers’ engineering, construction and maintenance work. Its electric-utility and generation business offers a broad read on the infrastructure spending MasTec also serves.
Primoris Services competes with MasTec to build and maintain utility networks, communications infrastructure and energy projects for their operators. Watch its U.S. utility-network work and its renewable-energy and storage business for spending trends in markets both serve.
MYR Group competes with MasTec for electric utilities’ work building and maintaining transmission lines, distribution networks and substations. Its Transmission and Distribution results are the relevant comparison for MasTec’s Power Delivery business, rather than its commercial-building work.
Dycom Industries and MasTec compete for communications providers’ network engineering, construction, installation and maintenance spending. Dycom’s fiber and wireless construction work is the useful comparison for MasTec’s Communications business.
SOLV Energy competes with MasTec for customers’ utility-scale solar and battery-storage design and construction contracts. Watch its new-project construction business: its maintenance of existing plants is a different source of revenue.
Centuri Holdings competes with MasTec for electric and gas utilities’ network construction, replacement and maintenance work. Its gas-network replacement and electric-network upgrades offer a view of the utility modernization spending both pursue.
AT&T directly feeds MasTec’s revenue by buying wireless and wireline network construction, installation and maintenance; it accounted for approximately 10% of MasTec’s consolidated revenue in 2025. AT&T sells connectivity to consumers and businesses, so watch its wireless and fiber-network spending for the implications for MasTec’s Communications work.
Argan and MasTec pursue power producers’ and utilities’ engineering and construction work for gas-fired, renewable and other generating plants. Argan’s Power business is the part to watch for activity in generation projects, including solar with battery storage.
ITG competes nationally with MasTec for broadband and fiber providers’ network design, construction, installation and maintenance work. Its large-scale fiber builds and home and business installations show two parts of the broadband spending MasTec also serves.
Everus Construction Group competes with MasTec for utility transmission and distribution work, renewable-energy installations and electrical construction. Watch its utility business for electric and gas network spending, and its electrical business for work paid for by general contractors and end users.
Sterling Infrastructure overlaps with MasTec in construction for data centers and industrial customers, as well as roads and bridges. Its data-center site development and electrical work offer a different view of the same customer spending than its transportation construction revenue.
EMCOR competes with MasTec for customers’ electrical, communications and industrial infrastructure construction work. Its power-distribution and communications-system installations are the useful overlap to watch, rather than its broader building-maintenance services.
GE Vernova and MasTec serve the same generation and grid investment from different sides: GE Vernova sells equipment to power-system customers, while MasTec builds plants and transmission and distribution infrastructure. Watch GE Vernova’s Power, Wind and Electrification businesses for the equipment side of that spending—not as evidence of a direct supply relationship with MasTec.
Comfort Systems USA overlaps with MasTec in electrical and industrial construction paid for by technology and manufacturing customers. Watch revenue from those two customer groups for a read on shared construction demand, rather than treating all of its plumbing and mechanical work as comparable.
IES Holdings overlaps with MasTec in installing electrical and technology infrastructure for data-center and industrial customers. Its Communications business, with repeat work for technology, social-networking and e-commerce customers, is more relevant to that overlap than its residential business.
AT&T Inc. earningsT
AT&T's report shows whether it is maintaining spending on the wireless and fiber networks that generate construction work for MasTec's Communications business.
Read AT&T's network investment and wireless and fiber build activity alongside revenue and work in hand in MasTec's Communications business. Steady or rising investment and construction would indicate that this major customer still needs network work; cuts or delays could mean less work for MasTec. AT&T's total spending is not the same as orders for MasTec, so the two companies' reports need to be read together.
EIA Crude Oil Stocks Change (Oct/16)
The EIA’s weekly stocks report tracks crude oil and fuel inventories; for MasTec, evidence of looser oil supply can mean lower prices, less exploration activity and fewer or delayed Pipeline Infrastructure jobs for energy customers.
Rising stocks would suggest looser supply and possible pressure on oil prices, which could weaken or delay customers’ exploration and pipeline projects; falling stocks would suggest tighter supply and potentially more support for that work.
MYR Group, Inc. earningsMYRG
MYR Group's transmission and distribution results show how much utilities are spending on work that MasTec also bids to build and maintain.
Focus on MYR Group's transmission and distribution revenue and work activity, then compare them with MasTec's Power Delivery business. Strength at MYR would show utilities are still commissioning work in a market both companies serve, but would not mean MasTec won the same projects. If MYR weakens while MasTec holds steady, the difference may lie in MasTec's own execution or contract wins. The comparison helps separate market demand from MasTec's performance.
Sterling Infrastructure, Inc. earningsSTRL
Sterling Infrastructure's data-center site and electrical work shows whether customers are still funding projects that overlap with MasTec's infrastructure work.
Look at Sterling's data-center site-development and electrical work, not its road and bridge revenue. Growth in that work would show data-center customers are moving projects ahead and support demand for similar work MasTec serves; weakness could mean customers are slowing or postponing projects. The companies may not serve the same customers, so this is a read on their shared market, not proof that MasTec won or lost a particular project.
Fed Interest Rate Decision
The Fed’s policy-rate decision matters to MasTec because it can change interest costs on variable-rate debt, leaving less or more cash for its infrastructure work and investment.
Expected4.0%Last release4.0%
If it comes in above expectations
Higher rates can raise interest costs on MasTec’s variable-rate debt, reducing cash available to run projects and invest in equipment or other needs.
If it comes in below expectations
Lower rates can ease interest costs on MasTec’s variable-rate debt, leaving more cash available for its projects and investment.
MasTec, Inc. earningsThis company
MasTec's customers can delay or cancel work, while fixed-price projects leave it exposed to cost overruns; this report shows whether work in hand is turning into revenue without squeezing profit and cash.
Read revenue by segment alongside profit margins and cash from operations. Rising revenue with margins holding and cash keeping pace would show that work is progressing without costs eating away the return. If revenue or margins weaken, or cash fails to keep up, delays, labor and material overruns, or slower customer payments may be weighing on projects. The combination shows whether work in hand is turning into deliverable business or bringing more execution and collection pressure.
JOLTs Job Openings (Sep)
Job openings track employers’ demand for workers; for MasTec, tighter competition for the skilled crews that build and maintain infrastructure can raise labor and training costs on its customer work.
Expected7.0MLast release7.079M
If it comes in above expectations
More openings may signal tighter hiring conditions, making it harder for MasTec to staff communications, energy and utility projects without higher wages or training costs.
If it comes in below expectations
If the reading is below the 7.0M estimate, it is below the previous 7.079M. Fewer openings may signal easing hiring pressure, making it easier for MasTec to staff customer projects and limiting upward pressure on wages and training costs.
Dycom Industries, Inc. earningsDY
Dycom's fiber and wireless construction results show whether communications providers are still building networks and give a direct comparison for MasTec's Communications business.
Compare Dycom's fiber and wireless construction activity with revenue and work in hand in MasTec's Communications business. Strong Dycom results would show providers are still funding similar network builds, but would not mean MasTec is winning more of that work. If Dycom strengthens while MasTec weakens, contract wins or execution may differ; weakness at both would point more toward cooling demand across the market.
