The latest disclosure, reported on 06/03/2026, indicated that Northwestern Mutual Wealth Management Co. increased its holding in Quanta Services and that the stock opened at around USD 706.74 on Wednesday, highlighting the continued interest from U.S.-based institutional investors in the NYSE-listed PWR ticker.

Public price data for Quanta Services show that the stock last closed at about USD 706.06 on 06/02/2026, up 2.7 percent on the day, with the shares having gained roughly 104 percent over the past twelve months according to a U.S. market data provider.
