Upcoming earnings put Quanta Services in focus

Quanta Services (PWR) heads into its July 30 earnings release with the stock recently closing at $639.20, while consensus points to higher quarterly earnings per share and revenue compared with the same period last year.

Quanta Services’ share price has pulled back over the past month, with a 1‑month share price return of down 8.98%. However, the year‑to‑date share price return of 45.38% and 1‑year total shareholder return of 61.99% indicate strong underlying momentum.

If Quanta Services has your attention ahead of earnings, it can also be useful to compare it with other companies linked to power and grid upgrades, starting with the 35 power grid technology and infrastructure stocks

After such a strong run and a recent pullback, Quanta Services now sits between investors keen to buy the grid upgrade story on any dip and others wondering if patience will be rewarded. How does the valuation stack up?

Most Popular Narrative: 10% Undervalued

The most followed valuation narrative for Quanta Services pegs fair value at about $710 per share, compared with the last close of $639.20, which points to some upside baked into that view.

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 how this grid supercycle story turns into a $700 plus fair value? The narrative leans heavily on sustained double digit growth, expanding earnings power, and a thick backlog converting into cash. Curious which assumptions make that math hold together and how much execution headroom is left?

Based on this widely followed narrative, Quanta Services screens as modestly undervalued, with the fair value sitting above the current share price but still relying on strong delivery of its growth and cash flow plans.

Result: Fair Value of $710 (UNDERVALUED)

However, this Quanta Services narrative still hinges on tight execution and continued large project awards; any stumble or slowdown could quickly challenge that $710 fair value case.

Another View: Quanta Services looks expensive on earnings multiples

The user narrative argues Quanta Services is about 10% undervalued at $710 per share, but the earnings multiple tells a very different story. At a P/E of 86.8x versus the US Construction industry at 40.8x, peers at 49.6x and a fair ratio of 45.7x, investors are paying a heavy premium that leaves less room for disappointment. Which story do you trust more: the supercycle or the multiple?
