Why Is Vertiv Stock Up Sharply Over The Past Year Yet Well Below Its Peak?

Vertiv (VRT) stock gained 75.9% over the past year, more than four times the S&P 500’s 16.7% return. The company sells the power and cooling equipment that AI data centers depend on, and its sales and margins have grown fast. Yet the shares sit about a third below their 52-week high. The question analysts keep raising is delivery.

Vertiv Grew Sales And Kept More Of Each Dollar

In the second quarter of 2026, net sales rose 24% from a year earlier. The Americas and APAC each grew 29%, while EMEA grew 2%. New capacity is online, from Johor in Malaysia to five large plant expansions in the Americas.

Adjusted operating margin in the second quarter was 22.6%, up 410 basis points from a year earlier. More of each sales dollar now reaches profit.

The projects are getting bigger, too. VisionBay AI, Foxconn’s unit focused on AI supercomputing, picked Vertiv for power, thermal and services at an AI data center featuring NVIDIA GB 300. Vertiv is also working on what management calls the world’s first AI data center to adopt 800V DC at the rack and pod level.

But Vertiv’s Biggest Projects Pushed Some Revenue Into The Second Half

The same quarter showed the cost of that scale. Management described minor timing shifts in second-quarter revenue, driven mainly by multiphase project execution and temporary supply chain dynamics. The CFO expects the delay to resolve in the second half of 2026. The CEO calls it a learning curve on the first very large projects of this complexity.

Analysts were not fully persuaded. One asked whether the problem was a one-off or an ongoing issue. Another asked whether Vertiv was delivering to customers on time less often, and the CEO said no.

It is not the first stumble either. A year earlier the trouble was margins, tied to Ireland and execution challenges on busbar switchgear, which the CEO says Vertiv amply recouped. This time it is revenue.

Second-Half Performance Depends on Accelerated Execution

Management guides third-quarter 2026 net sales to $3.75 billion at the midpoint, up 40% from a year earlier. That is a big step up from the 24% growth of the second quarter. Management also raised its full-year 2026 sales guidance by $250 million, to $14 billion at the midpoint. The CEO says that guide does not assume every star aligns, and leans on faster execution, new capacity and a strong backlog.

In September, Vertiv agreed to buy UtilityInnovation Group, which designs microgrid and behind-the-meter power architecture for data centers. The deal was announced after that guide was set, and it does not settle what the second half must deliver. At a market value of about $95.9 billion, investors pay more than eight times Vertiv’s $11.48 billion of sales over the past twelve months. The business grew fast, and the gap to the high is a question about execution. To track whether outlooks like this keep rising, use our guidance-momentum screen.
