Is MasTec profitable in 2026?

Yes. MasTec posted record FY2025 revenue of $14.3 billion (up 16% YoY, reported 2026-02-26), and Q1 2026 adjusted EPS hit $1.39, up 174% YoY. FY2026 guidance targets ~$17.5B revenue and adjusted EPS of $8.79, per company results dated 2026-04-30.

MasTec (NYSE: MTZ) is publicly traded with a market cap of roughly $26.0 billion as of 2026-07-20. Founder-family members Jorge and Jose Mas reportedly hold about 21% ownership; Jose Mas is CEO and Jorge Mas is Chairman.

Could AI replace MasTec's construction workers?

No. MasTec's core business is physical infrastructure construction, requiring licensed electricians, welders, and heavy-equipment crews under regulatory permits and utility master service agreements. AI is a demand driver for MasTec (data-center buildouts) rather than a substitute for its skilled-labor workforce.

Who is MasTec's biggest competitor?

Quanta Services (PWR) is MasTec's largest direct peer in utility and data-center infrastructure. As of Q1 2026, Quanta's backlog stood at $48.5 billion versus MasTec's $20.3 billion, making Quanta the scale leader in the sector, per Zacks reporting dated 2026-06-29.

Will MasTec's Superior Group acquisition boost its data-center business?

MasTec announced a $1.65 billion acquisition of The Superior Group on 2026-07-07, adding about 3,000 employees specializing in 'inside-the-fence' data-center electrical work. The deal is projected to add $800-900M in 2026 revenue and reach $2.2-2.5B run-rate revenue by 2027.

Is MasTec laying off employees in 2026?

No layoffs are reported; headcount trended up roughly 9% YoY in 2025 to an estimated 32,000-36,000 employees (sources vary), and the July 2026 Superior Group acquisition is set to add about 3,000 more workers.

The call

MasTec's growth rides the same AI data-center wave that threatens other industries, with skilled labor and utility relationships keeping rivals from taking its contracted work.

MasTec is a construction company that hires licensed electricians, welders, and other skilled workers to build electrical systems, power grids, and data centers for utilities and tech companies. It is hard to replace because you need years of training, state licenses, and long-standing relationships with utilities to do this work, and no AI can lay cable or solder equipment. The big risk is that if Meta, Microsoft, Google, and Amazon slow down their data-center spending in 2027 or 2028, MasTec's incoming work orders will shrink, since nearly half its new business now comes from AI-driven data centers.

Why

AI pressure: None apparent. AI data-center buildouts by Meta, Microsoft, Google, and Amazon feed MasTec's backlog rather than threaten it; ~$1B added in Q4 2025 alone. Could AI do the core job? Unlikely.

Bigger players: Quanta Services. Quanta is bigger ($48.5B backlog vs MasTec's $20.3B) and chasing the same utility and data-center work, but the market is growing faster than either can absorb. Could a giant copy it? Probably.

What protects it. Licensed electricians and welders, decades-old utility master service agreements, and regulatory credentials that new entrants and software cannot replicate quickly.

What would change this call

MasTec's backlog shrinks two consecutive quarters versus prior quarter. Would suggest hyperscaler or utility capex is pulling back, weakening the growth thesis.
Superior Group integration produces margin dilution or crew attrition disclosed in earnings. Would show the $1.65B acquisition is straining execution rather than adding capacity.
A specific MasTec utility or hyperscaler contract is confirmed lost to Quanta Services at renewal. Would show a same-scale rival is actively taking named accounts, not just growing alongside MasTec.

Key numbers

FY2025 revenue $14.3B, up 16% YoY (2026-02-26)
Backlog $20.3B, 1.4x book-to-bill (2026-07-14)
$1.65B Superior Group deal adds ~3,000 workers (2026-07-07)

Named risks

Growth thesis heavily tied to hyperscaler AI data-center capex; a 2027-2028 pullback could soften backlog. Severity: high
Data breach litigation (Burke v. MasTec, Fraga v. MasTec) filed June 2026 over ~25,220 exposed records. Severity: medium
Superior Group integration execution risk on margins and crew retention post mid-to-late July 2026 close. Severity: medium
Headcount figures conflict across sources (30,000 to 36,000), complicating workforce capacity assessment. Severity: low
