Data center infrastructure provider Vertiv Holdings LLC on Wednesday handily beat Wall Street's targets for the fourth quarter. But its guidance was a tad light on earnings with sales above estimates. VRT stock fell 9% in premarket trading.

The Westerville, Ohio-based company earned an adjusted 99 cents a share on sales of $2.35 billion in the December quarter. Analysts polled by FactSet had expected earnings of 82 cents a share on sales of $2.16 billion. On a year-over-year basis, Vertiv earnings soared 77% while sales increased 26%.

For the current quarter, Vertiv expects to earn an adjusted 60 cents a share on sales of $1.93 billion. That's based on the midpoint of its outlook. Wall Street was modeling earnings of 63 cents a share on sales of $1.92 billion.

For full-year 2025, Vertiv is targeting adjusted earnings of $3.55 a share on sales of $9.2 billion, based on the midpoint of its guidance. Analysts had been expecting earnings of $3.57 a share on sales of $9.13 billion.

"I am confident in the growth trajectory of Vertiv, and we are reaffirming the five-year financial framework we presented at our investor event last November," Chief Executive Giordano Albertazzi said in a news release.

He added, "In an increasingly advanced and efficient data center industry, we continue to bring the critical digital infrastructure technology, speed and scale needed to support this rapidly growing market."

Vertiv stock hit a record high of 155.84 on Jan. 24 but then tumbled in the tech sell-off sparked by China's low-cost DeepSeek AI system.

Vertiv provides power, cooling and information technology infrastructure solutions for data centers, communication networks and commercial and industrial facilities.
