Quanta Services stock (ISIN US7493391038) is trading in the upper half of its recent range, with Quanta Services Inc. closing at USD 619.28 on the New York Stock Exchange on September 16, 2026, giving the infrastructure specialist a market capitalization of about USD 93.1 billion and a 52-week range between USD 376.07 and USD 788.75 per share according to finance data reported on September 17, 2026.

AI power backlog underpins Quanta Services stock

For investors, the most striking fundamental anchor behind Quanta Services stock right now is the company’s record order book tied to power and data center infrastructure. According to Zacks in an analysis published on September 17, 2026, Quanta Services reported a record total backlog of USD 53.4 billion at the end of the second quarter, up 49 percent from the prior year, with electric power work accounting for about 82 percent of that total.

This backlog is closely linked to AI-driven investments in power transmission and data center infrastructure. As TheStreet reported on September 17, 2026, a portfolio manager highlighted that Quanta’s backlog of about USD 53 billion is driven by AI-related power projects and noted that management has raised four-year guidance, with data center work estimated to account for roughly 80 to 90 percent of each buildout excluding chip content.

Options market shows heavy put skew ahead of earnings

While the backlog supports the long-term story for Quanta Services stock, the derivatives market is sending a more cautious near-term signal. According to Investing.com on September 17, 2026, options on Quanta Services showed around 5,331 puts versus just 245 calls as of 11:41 a.m. Eastern time, resulting in a put/call ratio of roughly 21.8 times, with notable volumes concentrated in a September 18, 2026 USD 560 put and an October 16, 2026 USD 530 put.

Despite that skew, implied volatility has eased rather than spiked. The same Investing.com report notes that three-month implied volatility slipped by 1.41 percentage points to 43.57 percent, while the 90/110 options skew compressed by 0.88 percentage points to 0.16 percentage points, suggesting that investors may be managing existing downside hedges rather than aggressively initiating new speculative positions.

Earnings expectations and recent performance

The next scheduled earnings report is an important milestone for Quanta Services stock. According to AltIndex in an earnings calendar update dated September 17, 2026, Quanta Services is expected to report its next quarterly results on October 28, 2026, with analyst consensus pointing to earnings per share of USD 2.36 for the quarter.

Board and governance developments

That appointment is accompanied by standard non-employee director compensation in cash retainers and restricted stock units, aligning her incentives with the performance of Quanta Services stock. The same press release also alludes to a recent analyst view characterizing the shares as a Hold with a price target of USD 748.00 and points to TipRanks’ AI Analyst tool labeling PWR as Outperform, underscoring mixed but generally constructive sentiment around valuation and growth prospects.
