Quanta Services (PWR) is back in focus after lifting its 2026 revenue outlook to a range of US$41.3b to US$41.6b, alongside reporting sharply higher quarterly sales and earnings.
Even with the raised 2026 revenue outlook and strong third quarter figures, Quanta Services’ share price has pulled back sharply in the short term, falling 11.65% on the day and 15.07% over 30 days. However, the year-to-date share price return of 32.01% and a very large 5 year total shareholder return signal that long term momentum has still been strong as investors weigh rapid operational progress against higher expectations and shifting risk perceptions.
