Worthington Enterprises beat on both lines for its fiscal first quarter, and its stock surged as much as 18.8% after the bell. The chief executive pointed investors toward an unexpected growth engine: liquid cooling for AI data centers.
Worthington Enterprises is an industrial manufacturer that rarely draws a crowd. On Tuesday evening, its shares traded like those of an AI supplier.
The company reported fiscal first-quarter net sales of $343.9 million, up 13% from a year earlier and ahead of the $331.3 million analysts had expected. Earnings came to 82 cents a share, beating the 75-cent consensus by roughly 9%. Shares surged as much as 18.8% in extended trading and were still up about 16% before Wednesday's open.
The size of the move reflects what management said about where growth is coming from, not just the beat itself. Chief Executive Joseph Hayek said the company is seeing opportunities across its business, "including rapidly growing demand for our engineered [American Society of Mechanical Engineers] tanks used in liquid cooling systems for data centers."
That line connects a mid-cap industrial to one of the most crowded themes in the market. As AI data centers pack more high-powered chips into each rack, operators are shifting from air cooling to liquid cooling systems that need pressure-rated vessels to hold and circulate coolant. Worthington's ASME-certified tanks fit that need, which gives investors a new way to think about a business that has not traditionally been valued as an AI play.
The revenue beat was modest, at about 3.8% above expectations. The earnings beat was larger, suggesting margins held up better than analysts modeled. Together they gave investors a clean result on which to hang a new story.
The open question is scale. How much of Worthington's revenue comes from data-center applications today will shape how far this story can run, and a single quarter of "rapidly growing demand" does not establish how large that business can become relative to the company's established product lines. A near-19% after-hours jump prices in a meaningful contribution. The next few quarters will show whether data-center tanks become a line item investors can track or remain a promising remark on a conference call.
For now, Worthington joins a growing list of industrial suppliers whose valuations are being reset by exposure to AI infrastructure spending. The regular session will offer the first test of whether that enthusiasm holds once the broader market opens.
