Most people chasing AI infrastructure have piled into chips. That’s fine. But there’s a layer underneath the chips that doesn’t get nearly enough attention — the physical systems that keep those chips from melting.
Every GPU cluster that gets switched on needs power. It needs cooling. And as racks get denser, air cooling doesn’t cut it anymore. That’s where Vertiv comes in.
What Vertiv actually does
Vertiv Holdings has become one of the most direct ways to play AI-driven data center power and cooling buildouts.
Vertiv designs and sells the physical infrastructure inside data centers, including uninterruptible power supplies, switchgear, busways, and racks — as well as thermal management equipment such as chillers and computer-room air handling solutions, plus liquid cooling offerings (including coolant distribution units).
Think of it as the circulatory and cooling system of every major AI build happening right now.
Morningstar views Vertiv as a pure-play on data center spending, as it derives over 80% of revenue from that end market.
Q1 numbers were hard to ignore
Vertiv delivered Q1 2026 results with 30.1% year-over-year net sales growth to about $2.65 billion, led by roughly 53% Americas growth.
Adjusted diluted EPS grew 83% year over year. Diluted EPS grew 136%.
Margin expansion at that revenue scale is the part that separates real businesses from hype plays.
Then there’s the backlog. Vertiv disclosed an estimated combined order backlog of $15.0 billion as of December 31, 2025, and said the majority is expected to be shipped within the next 12 to 18 months.
That kind of visibility is rare in industrial companies. It means the revenue growth story isn’t speculative — it’s already sitting in the order book.
Raised guidance. Again.
After Q1, Vertiv’s 2026 outlook called for full-year net sales of $13.5 billion to $14.0 billion and adjusted diluted EPS of $6.30 to $6.40, with AI data center spending driving demand for power and thermal management systems.
That guidance was raised after Q1. Management didn’t trim expectations — they expanded them.
Vertiv also announced the acquisition of Strategic Thermal Labs (STL), positioning it to deepen its liquid-cooling system capabilities aimed at high-density AI workloads.
New Malaysia facility opened July 1. Bernstein initiated with an Outperform and a $416 price target. RBC Capital raised its target to $435 from $356. The institutional interest is not subtle.
The stock and the moment
Vertiv has rallied roughly 84% year-to-date.
During the past year, the stock moved between $110.06 at its lowest and $379.94 at its peak. It’s currently trading in the low $300s — off the all-time high, but still in a strong uptrend.
The context worth sitting with: traditional air systems are proving insufficient for modern AI clusters, and liquid cooling is becoming more common as heat loads rise.
A recent market outlook projected the global data center liquid cooling market could grow to about $29.2 billion by 2033 from about $5.7 billion in 2026.
Vertiv sits at the center of that shift.
The risk is real, though. Investors should be aware of the risk that hyperscale customers might eventually bring more cooling and power solutions in-house. Concentration in a handful of big cloud spenders is a genuine watch item.
Vertiv is expected to report Q2 2026 results on July 29, 2026, though the company has not confirmed the date. That’s three weeks away. The backlog is there. The demand is there. Whether the stock gives you a better entry before or after that report is the question worth thinking through.
