Quanta Services, Inc. (ISIN US74762E1029) closed at USD 636.71 on the NYSE on September 21, 2026, unchanged from the previous close. The stock was valued at USD 96.61 billion on September 22, 2026, giving the market a firm reference point as analysts reassessed its upside.

Bernstein sets a USD 748 target

According to The Globe and Mail on September 22, 2026, Bernstein analyst Hanxu Wang maintained a Hold rating and set a price target of USD 748.00. That target is USD 111.29 above the September 21 closing price, equivalent to 17.48 percent upside based on the cited figures.

The same report cited a broader analyst consensus of Strong Buy and an average price target of USD 797.40 on September 22, 2026. The difference between Bernstein's target and that average is USD 49.40, showing that the Hold view is more cautious than the aggregate target.

Range leaves room for debate

Quanta Services traded between USD 387.42 and USD 788.75 over the 52 weeks ending September 22, 2026. At USD 636.71, the share price stood USD 152.04 below the high and USD 249.29 above the low, placing it closer to the upper half of the recorded range.

That positioning makes the valuation debate more demanding: the stock would need to rise 23.89 percent from the September 21 close to reach the reported 52-week high, while Bernstein's target remains 5.16 percent below that high. The numerical gap between the USD 748 target and the USD 797.40 consensus is therefore material for investors comparing individual analyst views with the wider market estimate.

Stock stays tied to execution

Quanta Services remains classified in the Industrials sector and Engineering and Construction industry, with NYSE ticker PWR. The September 22, 2026 market snapshot assigned the company a 72 out of 100 fundamentals score, while the cited 52-week range placed the shares at 64 percent of that range.

The combination of a USD 748 Bernstein target, a USD 797.40 average target and a USD 636.71 closing price puts execution against expectations at the center of the stock story. The figures describe analyst positioning rather than a recommendation.
