Western Digital, Super Micro and Vertiv top AI infrastructure screen

Western Digital, Super Micro and Vertiv top AI infrastructure screen

3 Key Points

  1. What happened

    Simply Wall St screened AI infrastructure stocks, flagging Western Digital (US$12.9b HDD revenue), Super Micro Computer (US$39.1b server revenue) and Vertiv, whose Q4 2025 organic orders surged 252% year-over-year.

  2. Why it matters

    The three are the physical backbone of the AI buildout — storage, GPU-dense server racks, and power and cooling — so their orders and margins move with hyperscaler spending rather than AI hype, Simply Wall St says.

  3. What to watch

    Western Digital's story rests on the storage duopoly holding the line on capacity, since a new entrant chasing demand could turn the shortage into a glut. Vertiv's Q4 2025 organic orders and $15 billion backlog are the figures to track.

WHO IT HITSInvestors weighing AI infrastructure exposure get three named companies to size against the theme — Western Digital in data center storage, Super Micro Computer in AI server racks, and Vertiv in power and cooling. Pricing power and backlog conversion are the swing factors the article flags for each.

Context & Analysis

Simply Wall St's screen frames the current AI buildout as a story about physical infrastructure rather than models. Its starting observation is that strong AI-related investment is helping keep inflation pressures alive in Singapore, which it reads as money pouring into the backbone that lets AI run at scale. From that, it selects three companies it sees as the hardware, power and cooling layer of the theme, and notes that the full screen surfaced another 84 companies it did not unpack.

The three profiles sit at different points in the stack. Western Digital supplies the high-capacity data center HDDs that let hyperscalers store and sift AI training and inference datasets, and its HDD business generates US$12.9b, concentrated in the United States at US$5.2b and China at US$2.5b. Super Micro Computer is closer to the compute itself, with US$39.1b from high performance server solutions and roughly US$27.7b of that from the United States, and it cites its Data Center Building Block Solution launch as supporting a higher-margin product mix. Vertiv handles the power and heat problem, with roughly US$7.5b of revenue from the Americas, and it notes liquid cooling growing roughly 20–30% annually as hyperscalers like Microsoft, Google and Amazon build AI infrastructure.

Across all three, the article returns to the same hinge: how an order book or a pricing position converts into durable margins and cash. For Western Digital it is whether the storage duopoly holds capacity discipline; for Super Micro Computer it is how the AI server backlog turns into sustainable cash and margin levels; for Vertiv it is whether a $15 billion backlog converts into long-term margin and cash flow. The article presents this as an open question for each company rather than a settled outcome, and it explicitly states the content is general commentary built on historical data and analyst forecasts, not investment advice.

FAQ
Why are Western Digital, Super Micro Computer and Vertiv grouped together?
Simply Wall St frames them as the 'picks and shovels' of AI — the hardware, power and cooling behind the buildout. Western Digital supplies data center HDDs, Super Micro Computer builds GPU-packed AI racks, and Vertiv supplies power, cooling and liquid-thermal systems.
What is the main risk Simply Wall St flags for Western Digital?
The storage duopoly holding the line on capacity. If either incumbent, or a cash-rich new entrant, chases demand with new plants, the shortage becomes a glut, as the article says has always happened in memory and storage.
How large is Vertiv's backlog and what does it equal?
Vertiv's $15 billion backlog is equivalent to roughly 1.5 years of trailing revenue, and its Q4 2025 organic orders surged 252% year-over-year.
