The AI rush around Nvidia, from its new $550 price target to quarterly revenue of $96.2b, is shining a harsh light on a less glamorous piece of the story. None of this computing power works without serious upgrades to power and cooling. That creates both potential winners and risks for investors watching this sudden build out. This article walks through three stocks exposed to that theme through our AI data center power and cooling screener.
The three stocks in this article are just a starting sample, and the full screen surfaced 60 more companies with equally compelling AI data center power and cooling narratives that are not covered below. To go deeper, head straight into the AI Data-Center Power & Cooling Infrastructure screener to identify, compare and analyze the highest conviction plays in this theme.
Overview: Siemens Energy is a global energy technology company that supplies the heavy hardware needed to generate electricity and move it across grids, including gas and steam turbines, high voltage direct current systems, transformers, switchgear and grid connections that can support power hungry AI data centers. It also operates a large wind business through Siemens Gamesa and provides long term services and digital solutions to utilities, industrial customers and infrastructure projects worldwide.
Operations: Siemens Energy generates most of its €45.8b revenue from Gas Services (€13.4b), Grid Technologies (€12.9b) and Siemens Gamesa (€10.4b), with additional contributions from its Transformation of Industry segment (€5.9b) and broad geographic exposure across Europe, the United States and other international markets.
Market Cap: €129.0b
Investors watching Nvidia driven AI build outs may want to look at Siemens Energy because it supplies the high voltage equipment, transformers and fast deployable turbine systems that help bring grid scale power to hyperscale and AI data centers. The company is tying that hardware edge to fundamentals that currently include high return on equity and improving profit margins, along with a stated growth outlook from management. At the same time, a premium P/E against peers and reliance on external borrowing create execution and financing risks if large grid and data center projects slow or become harder to fund. The full story on valuation, backlog quality and wind restructuring is where things get more detailed.
Siemens Energy is linking high return on equity, profit margins and grid scale hardware to the AI power build out, yet the key question is how that story is priced today. The DCF valuation analysis for Siemens Energy hints at where expectations may be quietly out of sync.
Overview: Voltronic Power Technology is a Taiwan based manufacturer of uninterruptible power systems that keep electricity flowing when the grid flickers. This is a core requirement for hyperscale and AI data centers. Alongside UPS hardware, the company also sells PV inverters, energy storage systems, variable frequency drives and EV chargers across Taiwan and Mainland China.
Operations: Voltronic Power Technology generates essentially all of its NT$19,580 million revenue from manufacturing and trading uninterruptible power systems and inverters.
Market Cap: NT$92.2 billion
Voltronic Power Technology is attracting attention because its UPS products sit right in the plumbing that keeps power hungry AI servers online when the grid or onsite generation stumbles. The stock is linked to high forecast earnings growth and strong current and projected ROE, which hints at a solid position in backup power equipment even as reported net income and EPS for the first half of 2026 moved down sharply year on year. A rich P/E multiple and reliance on external borrowing mean expectations are already high and balance sheet risk matters. The real interest lies in whether Voltronic can turn today’s AI infrastructure enthusiasm into sustained, profitable demand for its UPS and inverter portfolio without further pressure on margins.
Voltronic Power Technology’s AI linked UPS story is attracting high expectations, yet the real question is whether earnings and ROE can keep pace. Get the full picture in the analyst forecasts for Voltronic Power Technology before one key pressure point becomes obvious
Overview: Auras Technology manufactures computer cooling modules that pull excess heat away from GPUs, CPUs and other high power components in AI servers, gaming notebooks, graphics cards and industrial PCs across global tech hubs. Its products also support smartphones, tablets and even electric vehicles, giving the company broad exposure to thermal management needs as hardware gets denser and more power hungry.
Operations: Auras Technology generates all of its NT$30.8 billion revenue from electronic components and parts, with sales spread across Taiwan, China, the United States, Ireland and other regions.
Market Cap: NT$98.7 billion
Auras Technology gives you direct exposure to the cooling hardware that heavy AI workloads depend on. At the same time, its own numbers are moving sharply higher, with Q2 2026 sales at NT$8,700.12 million and net income at NT$968.91 million. High and improving returns on equity and profit margins suggest the company is converting AI related demand into solid profitability, while some estimates indicate the stock trades below certain fair value models even with a higher P/E than many Taiwan tech peers. The catch is that high non cash earnings, reliance on external borrowing and above average share price volatility raise questions about cash quality and funding resilience. The real opportunity lies in how those strengths and risks balance as AI data center cooling ramps up further.
Auras Technology’s accelerating sales and high returns are only half the story. The bigger question is how long AI driven demand can support those margins. Get the context in the analysis report for Auras Technology
