Three AI infrastructure hardware companies, Celestica, Jabil, and Vertiv, are being watched as rate expectations soften and cheaper capital makes long-horizon data center buildouts easier to finance. Celestica’s Helios rack platform (built with AMD) is pulling hyperscaler orders hard enough that the company raised equity to fund capacity. Jabil is betting on a multi-gigawatt AI rack facility in India via an Adani partnership. Vertiv supplies the liquid cooling and high-density power systems that GPU racks consuming 100 kilowatts or more now require. The full analysis of AI infrastructure hardware stocks covers all three in detail.
What this means for your business
If your organization is mid-cycle on a data center expansion or GPU cluster procurement, the supply chain behind your hardware is more concentrated than your vendor contracts suggest. Celestica, Jabil, and Vertiv sit between your cloud provider or hardware OEM and actual delivery. When any of these manufacturers slips on a capacity ramp, lead times stretch upstream, and the hyperscaler promising you a rack deployment date is quoting from a backlog that depends on these companies executing cleanly.
The deeper structural point is that AI compute infrastructure has developed a financial leverage problem that is separate from the technical one. All three companies fund growth heavily through external borrowing, meaning their ability to scale capacity is partly a bet on rates staying accommodative and orders not softening simultaneously. Vertiv’s 36.4% ROE looks impressive until you notice that high ROE built on high debt is fragile the moment demand hesitates. For enterprise buyers, a supplier with a stretched balance sheet and a concentrated hyperscaler customer base is a single-order-cancellation away from a capacity crisis that lands on your procurement timeline, not theirs.
The piece is written by SimplyWall St, a platform that monetizes retail investor screener subscriptions, which tilts the framing toward stock-picking cues rather than supply chain risk, but the underlying operational data points hold regardless of that context. Vertiv’s backlog is real. Celestica’s equity raise to fund capacity is real. What the retail framing understates is that these companies’ valuations already price in near-flawless execution, which means any enterprise buyer treating their commitments as firm should be building schedule buffer now. The vendor that looks best positioned on paper is usually the one most exposed when consensus is wrong.
