Vertiv Is Up 86% This Year. Q2 Earnings Land July 29.

There is a stock up 86% year-to-date that almost nobody is calling a bubble. That is unusual. Usually by the time something doubles, half the internet is screaming sell. With Vertiv (VRT), the crowd is mostly quiet. And the quiet might be justified.

Here is the thing. Vertiv is not a chip company. It is not software. It sits between the utility grid and the server racks, selling the power systems, cooling units, and critical infrastructure that has to exist before a single GPU can do anything useful. Every AI data center that goes up needs Vertiv’s products first. That is a different kind of moat than most investors think about.

What Happened

Q1 2026 results landed on April 22. Revenue hit $2.65 billion, up 30% year-over-year, driven by 23% organic growth and 44% organic expansion in the Americas. Adjusted EPS came in at $1.17, up 83% from Q1 2025, beating consensus by roughly 15%. Adjusted operating margins expanded to 20.8%, up 430 basis points from the year-ago quarter.

The stock has moved from around $160 at the start of the year to roughly $318 as of July 9, 2026. The 52-week range runs from about $110 to about $380.

After Q1, management raised the full-year 2026 revenue outlook to $13.5 billion to $14.0 billion and held adjusted EPS guidance at $6.30 to $6.40. Operating cash flow in the quarter was $767 million, up 153% year-over-year. Net leverage sits at roughly 0.2x. The balance sheet is in good shape.

What the Business Actually Does

Vertiv designs and sells uninterruptible power supplies, switchgear, busways, chillers, computer-room air handlers, and liquid cooling distribution units. Over 80% of revenue comes from data center customers. This is not cyclical hardware in the traditional sense. When a hyperscaler commits to a build, Vertiv’s products are ordered before the construction crew shows up.

Liquid cooling is the specific growth driver worth watching. Traditional air cooling is proving insufficient for modern AI clusters running dense GPU configurations. The global data center liquid cooling market is projected to grow from approximately $5.7 billion in 2026 to $29.2 billion by 2033, according to Persistence Market Research. Vertiv has been deliberately positioning itself at this transition point, most recently acquiring Strategic Thermal Labs in April 2026 to strengthen cold-plate engineering and high-density thermal validation capabilities.

On top of that, Vertiv opened a new manufacturing facility in Johor, Malaysia on July 1, 2026, expanding its footprint to support demand across Asia as data center buildouts accelerate in the region.

Slight tangent, but it matters: the company is also positioning itself around 800 VDC architecture for next-generation AI data centers. Bank of America flagged Vertiv’s 800 VDC sidecar solution as a product expected to ship in 2027. That is not a near-term revenue event, but it suggests the product roadmap extends well past the current cycle.

The Backlog

The order book is the real story here. Vertiv ended Q4 2025 with a $15.0 billion backlog, up 109% year-over-year, with a book-to-bill ratio near 2.9x. That means for roughly every dollar shipped, nearly three dollars in new orders were coming in. As of March 31, 2026, the backlog stood at $12.45 billion, reflecting revenue conversion from that record base. Orders are still expected to be up year-over-year in 2026, per management guidance.

Backlogs represent signed purchase orders, not press releases. That distinction matters when evaluating whether AI infrastructure spending is real capital commitment or just announced intention.

The Valuation Argument

This is where it gets complicated.

At roughly $318 per share, VRT trades at an elevated trailing multiple. The 5-year beta is commonly reported around 2.0, meaning this stock moves fast in both directions. A 50% drawdown is not a theoretical risk. It happened in 2023 and again briefly in 2024.

The bull case for the multiple rests on three numbers: 30% revenue growth, 64% adjusted operating profit growth, and a backlog that keeps converting. Analysts projecting Q2 adjusted EPS of $1.43 are pricing in roughly a 50% year-over-year increase from the year-ago quarter. The company has beaten bottom-line estimates in each of the last four quarters. Management’s own Q2 guidance range is $1.37 to $1.43, so the Street is sitting at the high end.

25 analysts cover VRT. The consensus is Strong Buy. The average 12-month price target is approximately $363, per Barchart data as of early July.

The Risk Nobody Talks About Enough

Hyperscalers are the customers. If Amazon, Microsoft, Google, or Meta slow their AI capex commitments, even briefly, VRT shares will feel it faster than almost any other infrastructure name. The beta cuts both ways.

There is also put activity worth monitoring. Recent sessions have seen elevated put volume in VRT. That is not necessarily alarming at this price level and this volume, but it is a signal to keep an eye on going into earnings.

What to Watch on July 29

• Q2 adjusted EPS vs. consensus of $1.43
• Order backlog update and book-to-bill direction
• Full-year guidance revision: up, maintained, or trimmed?
• Any commentary on liquid cooling mix as a percentage of revenue
• Americas organic growth rate vs. Q1’s 44%

The Q2 report is the first real test of whether the stock’s 86% run reflects fundamentals or momentum. Both can be true at the same time. Until they are not.

Worth a look before July 29.
