Vertiv shares fell about 14% in premarket trading on Wednesday after the company’s second-quarter revenue missed Wall Street estimates. The data centre equipment maker reported net sales of $3.27 billion, up 24% from a year earlier. But analysts were expecting $3.38 billion. That small miss was enough to hurt the stock because Vertiv had already risen about 67% this year through Tuesday’s close.The company did better on profit. Adjusted earnings rose to $1.52 a share, above analysts’ estimate of $1.43. Net income increased to $497.8 million, or $1.27 a share, from $324.2 million, or 83 cents a share, a year earlier.Vertiv said revenue was affected by “minor timing shifts.” The company blamed temporary supply chain congestion and the way large projects are being executed in phases.

Demand for Vertiv’s power and cooling systems remains strong as companies build more AI data centres.
