Why Quanta Services Stock Is Back in Focus

Quanta Services (PWR) is back on investors radar after reporting record second quarter 2026 results and lifting its full year guidance, supported by strong AI related power demand and recent acquisitions.

Quanta Services share price has cooled slightly in recent months, with a 90 day share price return that is down 9.8%, even as the 1 year total shareholder return sits at 74.1% and the 5 year total shareholder return is very large at close to 7x. This points to strong long term momentum. The latest record quarter, higher full year guidance and recent multi tranche debt issuance around US$2.0b at fixed coupons have pulled the stock back into focus, as investors reassess both growth potential and balance sheet risk at a last close of US$671.86.

After a record quarter, a fresh guidance lift and roughly US$2.0b of new fixed rate debt, Quanta Services now trades near US$671.86 following a recent pullback. Does that combination still leave the risk reward skewed toward buyers?

Most Popular Narrative: 5.4% Undervalued

The most followed Quanta Services narrative pegs fair value at $710 per share, slightly above the last close of $671.86. This puts the focus firmly on what assumptions sit behind that gap.

Quanta is one of the clearest “picks-and-shovels” beneficiaries of the U.S. power infrastructure supercycle. It does not sell electricity, own data centers, or manufacture GPUs. It builds the transmission lines, substations, distribution systems, industrial electrical systems, underground utility networks, and other physical infrastructure that make those end markets possible. In 2025, Quanta delivered $28.5 billion of revenue, $2.9 billion of adjusted EBITDA, $10.75 of adjusted EPS, $2.0 billion of operating cash flow, and $1.7 billion of free cash flow, all while ending the year with a record $44.0 billion backlog.

Want to see why this narrative argues Quanta Services is still underpriced? The core is a step up in revenue, margins and free cash flow that pushes earnings power well beyond the current run rate. Curious which growth paths and profitability assumptions drive that $710 figure?

According to HedgeY, the fair value hinges on Quanta Services staying at the center of large scale grid, data center and manufacturing projects while converting a sizeable backlog into higher earnings and cash generation at a discount rate of 8.59%. The narrative also connects that outlook to a multi year revenue ramp and higher adjusted EPS profile than the market price currently reflects.

Result: Fair Value of $710 (UNDERVALUED)

However, Quanta Services still faces two clear swing factors. Any slowdown in large project awards or weaker margins could quickly challenge a 5.4% undervaluation case.

Another View: What Multiples Say About Quanta Services

Quanta Services might look modestly undervalued on a $710 fair value narrative, but the current P/E of 76.1x tells a different story. It sits well above the US Construction industry at 39.3x, the peer average at 37.3x, and even the fair ratio of 41.7x. That gap suggests valuation risk if growth or sentiment cools.
