Data center power has become one of the most important bottlenecks in the AI buildout. New GPU clusters do not generate revenue when chips ship; they generate revenue when power, cooling, switchgear, UPS systems, busway, backup generation, and commissioning are all in place. That makes this theme more durable than a narrow software trade, because it sits inside the physical infrastructure required to turn AI capital spending into usable compute capacity. In today’s market, that is pushing investors toward companies tied directly to the electrical and thermal chain behind hyperscale and colocation expansion.
The opportunity is broad, but not all exposure is equal. Some companies are upstream electrical infrastructure enablers serving utility interconnects, substations, and load centers. Others sell the critical hardware inside the facility, including power quality equipment, switchgear, racks, and thermal-management systems. A smaller group focuses on time-to-power and uptime through on-site generation or fuel-cell systems. Recent industry commentary has reinforced that demand is still accelerating, while annual-report disclosures from select HVAC names show that data center cooling has become a clearly identifiable growth engine rather than a vague AI adjacency.
This list focuses on seven US-listed stocks with meaningful relevance to the data center power chain, ranked by investment quality rather than pure upside. That means the countdown balances business fit with profitability, growth, valuation, earnings execution, and composite quality metrics. The order runs from #7 to #1, with the strongest overall pick revealed at the end.
For this screen, we looked at US-listed companies with market capitalizations above $500 million and clear exposure to data center power infrastructure, cooling, electrical equipment, distribution, or on-site power. We then ranked the finalists by investment quality, emphasizing business relevance to the theme, profitability, growth, earnings consistency, analyst sentiment, and composite valuation and balance-sheet signals. This is a countdown, so the names appear from #7 down to #1, with the best overall combination of theme fit and quality characteristics placed last.
What they do. The company provides infrastructure solutions across electric and gas utility, power generation, load center, manufacturing, communications, pipeline, and energy markets. Its Electric Infrastructure Solutions segment handles design, procurement, construction, upgrade, repair, and maintenance for transmission, distribution, substations, smart-grid projects, and commercial and industrial wiring, giving it a broad role in large-scale electrical buildouts.
Why it fits. Quanta is the most upstream name on this list, which is exactly why it matters for data center power. Before a hyperscale campus can energize a new hall, it needs utility interconnects, substations, transmission and distribution work, and often large load-center infrastructure; Quanta’s business description directly spans those categories, including substation facilities, electric power infrastructure projects, and load centers.
Numbers that matter. Revenue grew 26.3% year over year, while earnings growth was 51.0%, showing strong operating leverage against a very large $30.1 billion revenue base. Profitability is solid but not elite for this list, with a 15.1% gross margin, 4.24% operating margin, and 3.67% net margin, plus 13.53% ROE and 4.71% ROA. The valuation is the main constraint: trailing P/E is 98.97 and forward P/E is 51.55, while the composite quality framework flags both P/E and price-to-book as weak components.
Recent momentum. Quanta has beaten earnings estimates in 7 of the last 7 reported quarters. The latest reported quarter on April 30, 2026 delivered EPS of 1.45 versus a 1.00 estimate, a 45.0% surprise, following another beat in February with EPS of 3.16 versus 3.02. Analysts remain constructive but not aggressive, with 4 buys and 8 holds, and an average target of 759.81.
What they do. Eaton is a diversified power-management company with major electrical businesses spanning components, power distribution and assemblies, power quality and connectivity products, circuit protection, utility power distribution products, and power reliability equipment. That mix gives it a strong position in the hardware layer of electrical infrastructure, from the grid edge to the data hall.
Why it fits. Data center power demand is not just about generation; it is also about safely distributing, conditioning, and protecting electricity inside increasingly dense facilities. Eaton’s portfolio directly includes power quality products, utility power distribution products, and power reliability equipment, all of which are central to energizing and protecting AI-heavy data center capacity.
Numbers that matter. Eaton stands out for profitability, with a 37.1% gross margin, 16.1% operating margin, and 13.99% net margin. Returns are also strong at 20.84% ROE and 7.02% ROA. Revenue grew 16.8% year over year, though earnings growth was down 9.4%, which helps explain why it ranks below some faster-growing peers despite a more moderate valuation of 38.33 times trailing earnings and 29.41 times forward earnings.
Recent momentum. Eaton has delivered a 7-for-7 earnings beat streak. In the latest quarter reported on May 5, 2026, EPS came in at 2.81 versus 2.73 expected, a 2.9% beat, after a narrower 0.3% beat in February. Analyst sentiment is favorable but measured, with 7 buys, 10 holds, and 1 sell, alongside an average target of 450.81.
What they do. WESCO is a business-to-business distributor and supply-chain solutions provider operating across Electrical & Electronic Solutions, Communications & Security Solutions, and Utility & Broadband Solutions. Its model is less about proprietary manufacturing and more about product availability, logistics execution, and project support across electrical, communications, and utility infrastructure.
Why it fits. WESCO has unusually direct thematic relevance because its Communications & Security Solutions segment explicitly serves data center and network infrastructure, while its utility-focused business distributes transformers, transmission and distribution hardware, switches, protective devices, and power cables. In a market where long lead times and procurement complexity matter, a distributor with exposure to both data center and utility-side electrical gear can benefit from broad-based capex activity.
Numbers that matter. WESCO generated $24.25 billion in revenue with 13.8% year-over-year revenue growth and 48.1% earnings growth. Margins are thinner than those of equipment makers, which is typical for distribution: gross margin was 21.2%, operating margin 5.11%, and net margin 2.79%, with 13.40% ROE and 5.14% ROA. Valuation is more reasonable than many names on this list at 25.84 times trailing earnings and 23.58 times forward earnings.
Recent momentum. Earnings execution has been more mixed here, with beats in 4 of the last 7 quarters. The latest report on April 30, 2026 was strong, with EPS of 3.37 versus 2.83 expected, a 19.1% beat, but the prior quarter missed by 12.6%. Analysts still lean positive overall, with 3 buys, 1 hold, and 1 sell, and an average target of 375.00.

What they do.AAON engineers and manufactures air conditioning and heating equipment through AAON Oklahoma, AAON Coil Products, and BASX. Its product lineup includes rooftop units, air handling units, packaged outdoor mechanical rooms, coils, controls, cleanroom systems, and, crucially for this theme, data center cooling solutions.
Why it fits. Thermal management is inseparable from data center power density, and AAON is one of the cleaner direct plays because its description explicitly includes data center cooling solutions. The BASX segment matters here: it gives investors direct exposure to the cooling side of AI infrastructure rather than a generic commercial HVAC story.
Numbers that matter.AAON posted the fastest revenue growth on this list outside Bloom, with revenue up 54.3% year over year and earnings growth of 37.1%. Profitability is respectable, with a 26.2% gross margin, 11.55% operating margin, and 7.31% net margin, plus 13.50% ROE and 6.87% ROA. The trade-off is valuation: trailing P/E is 95.46 and forward P/E is 64.52, which is why the composite quality grade is only B- despite the strong operating backdrop.
Recent momentum. Results have been uneven but explosive when they hit. The latest quarter reported on May 7, 2026 delivered EPS of 0.48 versus 0.29 expected, a 65.5% beat, though the prior quarter missed by 13.3% and the August 2025 quarter missed by 44.1%. Analyst sentiment is cautious, with 1 buy and 3 holds, and an average target of 143.50.
What they do. Vertiv designs, manufactures, and services critical digital infrastructure technologies for data centers and communication networks. Its portfolio includes AC and DC power management products, low- and medium-voltage switchgear, busbar, single-phase UPS, rack power distribution, energy storage solutions, and both air-cooled and liquid-cooled thermal-management systems, plus lifecycle services.
Why it fits. This is one of the purest data center power names in the market. Vertiv touches multiple layers of the power chain inside the facility, from switchgear and UPS to rack power distribution and thermal systems, and its business description explicitly ties those products to technologies used for artificial intelligence and other digital workloads.
Numbers that matter. Vertiv combines strong growth with standout profitability. Revenue grew 30.1% year over year, while earnings growth surged 135.7%; margins were 37.2% gross, 16.36% operating, and 14.37% net. Returns are exceptional at 45.10% ROE and 11.15% ROA, but investors are paying for that quality, with a trailing P/E of 81.87 and forward P/E of 52.91.
Recent momentum. Vertiv has beaten estimates in 6 of the last 7 quarters. The latest report on April 22, 2026 showed EPS of 1.17 versus 1.01 expected, a 15.8% beat, although February brought a 12.3% miss. Analysts remain notably constructive, with 8 buys and 4 holds, and an average target of 377.21.
