Quanta Services stock gains on a raised 2026 outlook

Quanta Services stock (US74762E1029) closed at USD 636.71 on September 20, 2026, up 3.27 percent, with market capitalization at USD 93.8 billion. Reuters also showed 222,000 shares traded and a trailing 52-week range of USD 379.08 to USD 788.16 on its Quanta Services page.

Raised 2026 outlook

According to ad hoc news, Quanta Services lifted its 2026 revenue guidance to USD 39.3 billion to USD 39.7 billion and its net income outlook to USD 1.74 billion to USD 1.82 billion on September 19, 2026. The same report said the stock traded at USD 636.71, up 3.27 percent from the prior close of USD 616.54.

That guidance compares with 2025 revenue of USD 28.48 billion and net income of USD 1.03 billion, both reported by Reuters on September 21, 2026 through its Quanta Services profile. Revenue therefore rose USD 10.8 billion year on year, while net income increased by about USD 0.7 billion.

Valuation stays high

Reuters' Quanta Services page showed a trailing price-to-earnings ratio of 72.93, a price-to-sales ratio of 2.85 and return on equity of 5.61 percent as of September 21, 2026. The same page listed average analyst coverage of 32 analysts, which helps explain why the stock already reflects a full growth story.

For investors, the key point is the gap between the 2026 guidance and the 2025 base: revenue guidance points to growth of about 38 percent at the midpoint, while net income guidance implies another step up from last year's USD 1.03 billion. That is the number the market is pricing against.

Stock near its peak

Quanta Services stock ended the latest completed US session at USD 636.71 on September 20, 2026, according to Reuters. With the price far above the 52-week low of USD 379.08 and close to the 52-week high of USD 788.16, the chart still carries a strong premium.
