Quanta Services, Inc. (US74762E1029) stock is being shaped by a July 30 earnings release that showed second-quarter revenue of $9.56 billion and adjusted EPS of $4.24, while shares later traded at $637.35 on August 21, 2026. The same update lifted full-year revenue guidance to $39.5 billion and adjusted EPS guidance to $16.70.
Earnings still set the tone
A recent earnings overview said revenue rose 41.1% from the prior-year period and that EPS beat the $3.31 consensus by $0.93. It also said analysts expect full-year EPS of $15.35, while the company's own guidance sits above that level at $16.70.
The gap between the current outlook and the street estimate is a useful read for investors. It points to expectations that remain tied to execution, margins, and backlog rather than to a single trading session.
Valuation and trading context
Market coverage on August 21, 2026 put Quanta's market cap at $97.72 billion, with the shares down 3.8% to $637.35 and volume 57% below the average session level. Another market snapshot showed the stock at $639.34 on August 21, 2026, still up 51.6% year to date.
That combination matters because the stock is trading well above where it started the year while the company is also carrying a richer earnings profile after the second-quarter print. The result is a name where guidance, not just revenue growth, is doing the heavy lifting.
Acquisition backdrop
Quanta said it completed the acquisitions of Phalcon, Enerfab, Percheron, and PSD during the second quarter and July 2026 for $1.24 billion in upfront consideration. The businesses are expected to add $1.2 billion to $1.4 billion in 2026 revenue and $120 million to $140 million in adjusted EBITDA.
For investors, that is a second engine beside organic demand. It also gives the company more ways to defend the full-year targets it raised after the quarter.
What Quanta builds
Quanta's work centers on electric power, pipeline, and communications infrastructure, including transmission, substation, and underground utility projects. Those lines of business explain why the company can pair a $9.56 billion quarter with a raised $39.5 billion revenue target for 2026.
