Shares of X-Energy Inc. surged in their market debut on Friday, opening sharply above their initial public offering price after the company raised more than $1 billion in an upsized offering that drew strong investor demand.
The Rockville, Maryland-based nuclear energy firm priced its IPO at $23 per share, above the marketed range of $16 to $19.
The stock opened at $30.11, representing a gain of about 31%, and later traded as high as $31.33, up roughly 36% during the trading session.
The strong debut gave the company a market valuation of close to $12 billion based on outstanding shares, although some estimates placed its market capitalization nearer $9 billion.
The IPO was heavily oversubscribed, with demand exceeding available shares by more than 15 times, said a Bloomberg report.
Strong demand highlights investor appetite
The offering raised approximately $1.02 billion, surpassing earlier expectations of around $700 million, as investors responded positively to the company’s positioning in the nuclear energy sector.
“This is a validation of our nuclear technology,” X-Energy Chief Executive Officer Clay Sell said in an interview. “It’s a validation of the role that the market, and investors, believe nuclear energy must play.”
Interest in the IPO was further supported by institutional participation, with Ark Investment Management indicating it could purchase up to $105 million worth of shares at the IPO price, according to filings.
The listing was led by major investment banks including JPMorgan Chase & Co., Morgan Stanley, Jefferies Financial Group Inc., and Moelis & Co..
Technology and partnerships underpin growth story
X-Energy focuses on designing small modular nuclear reactors and manufacturing advanced nuclear fuel.
Its reactors use Triso fuel, consisting of tristructural isotropic, poppyseed-sized uranium kernels designed to burn hotter and longer than conventional fuel.
“We want to make nuclear boring,” Sell said. “We can build this over and over and over again. That’s the way you get costs down.”
The company aims to deliver its first reactor in the early 2030s, targeting industrial applications and power generation for artificial intelligence data centers.
A key differentiator for X-Energy is its commercial partnerships. The company has agreements in place with Amazon, Dow Inc., and Centrica Plc, with Amazon also acting as an equity investor.
“I think they were impressed with the validation that we’ve received from our tier one customers,” Sell said. “We’ve got great partners with big balance sheets.”
The company expects to receive licensing this year for its first reactor, which is planned for construction in Texas for Dow, with operations targeted in the early 2030s.
Additional projects are expected to follow, including reactors for Amazon in Washington state.
Financial profile and ownership structure
Despite strong investor interest, X-Energy remains an early-stage company with ongoing losses.
It reported a net loss of approximately $390 million on revenue of $94 million last year, excluding grants. This compares with a net loss of $126 million on revenue of $84 million in the previous year.
Ownership remains concentrated, with founder and chairman Kamal Ghaffarian controlling 61% of the company’s Class B shares. Affiliates of Ares Management Corp. hold an additional 26%.
The IPO comes as companies race to commercialize small modular reactors in the United States, a segment seen as critical for meeting future energy demand, particularly from power-intensive technologies such as artificial intelligence.
