PWR vs VRT: How Quanta Services and Vertiv Holdings Compare (2026)
Last updated August 2026
Short answer
PWR and VRT are similarly sized, but VRT trades noticeably cheaper on forward earnings (26.65x vs 36.54x): the market is paying up for PWR's profile and pricing VRT more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
PWR vs VRT: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | PWR | VRT | What it tells you |
|---|---|---|---|
| Market cap | $100.33B | $93.00B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 36.54 | 26.65 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 76.36 | 54.65 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.22 | 2.03 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 71% of range | 47% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 11.07 | 21.85 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: VRT is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how PWR and VRT affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. PWR and VRT share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined PWR and VRT exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Quanta Services (PWR) do?
Quanta Services is the largest specialty contractor for electric power, oil and gas pipeline, and communications infrastructure in North America. The company designs and constructs the physical infrastructure that delivers electricity from generation to customers: transmission lines, distribution networks, substations, and increasingly renewable energy interconnections. Quanta also has a meaningful underground utility infrastructure business (water, sewer, gas pipelines) and a communications infrastructure business (broadband, fiber).
What does Vertiv Holdings (VRT) do?
Vertiv Holdings designs and manufactures the power and cooling infrastructure inside data centers. The company's products include uninterruptible power supplies (UPS), power distribution units (PDUs), busways and rack power, computer room air conditioning (CRAC) units, liquid cooling systems, and increasingly the integrated thermal management solutions required to cool AI training racks at high density.
PWR vs VRT: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- PWR drivers: Grid investment and AI data center load; Renewable energy interconnection.
- VRT drivers: AI rack power and cooling; Liquid cooling adoption.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Utility regulatory cycles affect transmission and distribution capex pace. For VRT, hyperscaler AI capex concentration is the primary risk.
PWR or VRT: which should you pick?
PWR vs VRT: the full fundamentals
PWR. Quanta trades at a premium reflecting the grid investment tailwind, the AI data center load growth narrative, and the structural labor moat. The multiple has expanded with recognition that utility capex is entering a generational increase to support AI and renewable interconnection.
VRT. Vertiv trades at a premium reflecting the AI buildout tailwind, the demonstrated operating leverage, and the visibility from order backlog. The multiple is sensitive to AI capex cycle expectations; would compress on any hyperscaler pause.
Headline figures (approximate, early 2026): PWR shows revenue (ttm) ~$25 billion, operating margin ~7% (cyclical and labor-intensive), net income (ttm) ~$1.2 billion, eps (ttm) ~$8.00; VRT shows revenue (ttm) ~$9 billion, operating margin ~18% (improving), net income (ttm) ~$1 billion, eps (ttm) ~$2.50.
The bottom line: PWR vs VRT
PWR and VRT are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined PWR and VRT exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between PWR and VRT?
+
Quanta Services is the largest specialty contractor for electric power, oil and gas pipeline, and communications infrastructure in North America. Vertiv Holdings designs and manufactures the power and cooling infrastructure inside data centers. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is PWR or VRT the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, PWR or VRT?
+
On forward P/E (as of August 2026), PWR trades at 36.54x and VRT at 26.65x, so VRT is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both PWR and VRT?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of PWR vs VRT?
+
PWR: Utility regulatory cycles affect transmission and distribution capex pace. Skilled labor availability remains a long-term constraint. Margin pressure during labor inflation periods. Renewable interconnection demand depends on policy support. VRT: Hyperscaler AI capex concentration is the primary risk. A pause or reduction in AI data center buildouts would directly impact Vertiv's order book. Competition from larger industrial players (Schneider, Eaton) intensifies as AI cooling becomes mainstream.
