X-Energy, Inc. Class A Common Stock, XE
The Maryland-based developer of small modular nuclear reactors sold 44.25 million shares at $23 apiece — surpassing its previously announced pricing range of $16 to $19 per share. The offering size was also expanded from an initial target of 42.86 million shares.
Trading under the symbol XE on the Nasdaq, the stock debuted at $30.11. Shares touched an intraday high of $31.33 before settling lower.
Investor appetite proved overwhelming, with the offering oversubscribed by a factor exceeding 15-to-1. Approximately one-third of institutional demand went unfilled. Company leadership played an active role in determining final allocations.
The offering generated approximately $1.02 billion in total proceeds, significantly surpassing earlier projections of roughly $700 million.
The market debut valued X-Energy at approximately $12 billion based on shares outstanding, though alternative calculations suggested a figure closer to $9 billion.
According to regulatory disclosures, Ark Investment Management expressed interest in acquiring up to $105 million in IPO shares.
JPMorgan Chase, Morgan Stanley, Jefferies Financial Group, and Moelis & Co. served as lead underwriters for the transaction.
Technology and Commercial Backing
X-Energy specializes in small modular reactor design and advanced nuclear fuel production. The company’s reactors utilize Triso fuel — tristructural isotropic uranium particles roughly the size of poppy seeds — engineered to operate at higher temperatures and for extended periods compared to traditional nuclear fuel.
Chief Executive Clay Sell stated the company aims to make nuclear power generation predictable and standardized. “We want to make nuclear boring,” he explained. “We can build this over and over and over again. That’s the way you get costs down.”
The firm has secured commercial partnerships with Amazon, Dow Inc., and Centrica. Amazon also maintains an equity position in X-Energy.
Regulatory approval for the company’s inaugural reactor is anticipated this year, with construction slated for a Texas facility serving Dow. The reactor is expected to become operational in the early 2030s.
Further development projects are in the pipeline for Washington state in partnership with Amazon.
Financials and Ownership
X-Energy remains largely pre-revenue from commercial operations. The company reported a net loss of approximately $390 million on $94 million in revenue during the most recent fiscal year, excluding government grants. The previous year showed a net loss of $126 million on $84 million in revenue.
Operating losses have expanded as the company accelerates development efforts in preparation for its first commercial reactor launch.
Company founder and chairman Kamal Ghaffarian maintains control of 61% of Class B shares. Affiliates of Ares Management Corp. hold another 26%.
XE shares concluded their inaugural trading session approximately 27% above the IPO price.
