The stock for data center infrastructure company and Nvidia partner Vertiv (VRT -0.46%) is trading up 84% since the end of March. That growth could continue as the company's underlying momentum is being masked by the effect of tariffs and an acceleration in investment to fuel future growth.

Vertiv's quiet growth burst

The table below shows the progression of its full-year guidance in 2025. Vertiv's sales guidance outstrips its adjusted operating profit increases. Profit growth is lagging sales growth due to extra costs associated with tariffs and the pull-forward of investment in research and development to fuel growth.

In usual circumstances, it's reasonable to expect a company's operating profit to expand more than its revenue growth. Margins should improve in a manufacturing company when it has larger volumes due to the benefits of scale, such as increased production efficiency and lower fixed cost per unit production.

However, provided the tariff environment doesn't worsen for Vertiv, future orders and revenue increases are likely to translate into significant increases in profits and cash flow.

Where next for Vertiv?

Momentum continues to build in the data center end market, driven by torrid growth in artificial intelligence application demand. As such, Vertiv is in the early innings of a multi-year expansion in data center spending, and that includes its involvement in developing power systems and solutions for the next generation of data centers with Nvidia.

Vertiv has a bright future, and it's not too late to invest in it.
