IES Holdings Rises 7.7% as Data Center Growth Narrative Keeps Drawing Buyers

IES Holdings, Inc. (IESC) is up 7.7% today. Here is some analysis on what might have caused this price movement.

Analysis: The most likely driver appears to be continued investor enthusiasm around IES Holdings’ exposure to data center construction and infrastructure work, especially after the company posted strong fiscal second-quarter results in May. There does not appear to be a fresh company announcement tied directly to today’s move, so part of the gain could also reflect momentum buying in a stock that has already been trending strongly. This could be because investors are still re-pricing the company’s backlog growth, margin improvement, and expansion plans.

Details:

IES Holdings reported fiscal second-quarter revenue of $974 million, up 17% year over year, while diluted earnings per share rose to $5.44.

The company said demand in the data center market was the primary driver of growth in both its Communications and Infrastructure Solutions businesses.

Backlog reached about $3.9 billion as of March 31, 2026, and remaining performance obligations were about $2.3 billion, signaling a sizable pipeline of future work.

IES also completed the Gulf Island acquisition in January 2026 and said it is raising capital spending plans to support additional organic growth capacity.
