Holtec Nuclear suspends planned US IPO, Bloomberg News reports

By Thomson Reuters Sep 16, 2026 | 5:28 PM

Sept 16 (Reuters) – Holtec Nuclear has suspended its planned U.S. initial public offering, Bloomberg News reported on Wednesday, citing people ​familiar with the matter.

The IPO was put ‌on hold because of market conditions, the report said, citing one of the people.

Holtec did not immediately respond to a Reuters request for comment. Reuters could ‌not ​immediately verify the report.

The nuclear ⁠technology company was set ⁠to headline the first full week of the fall window, traditionally one of the busiest stretches for new listings.

Holtec was seeking ​up to $900 million by offering 50 million shares for between $15 and $18 apiece in its IPO, ⁠which was expected to ⁠be priced on Thursday.

A postponement would ​be the latest setback for issuers from the ​nuclear sector, where stocks have had a ‌tough run in recent months.

Standard Nuclear, which debuted in July after downsizing its U.S. IPO, has seen its shares plunge 20.6% from the offer ⁠price through Wednesday’s close.

Nuclear reactor maker X-Energy, which went public in April, is trading 36.7% below its ⁠IPO price.

Founded ‌in 1986 by Krishna Singh, Holtec ⁠specializes in areas such as heat ​transfer ‌and reactor components, spent fuel ​storage and ⁠nuclear plant decommissioning. The firm is also developing small modular reactors (SMRs), with the first two units expected to be deployed at its Palisades site.
