The nuclear small modular reactor (SMR) company based in Rockville, Maryland, set its offering price at $23 for 44.25 million shares — exceeding its projected $16 to $19 price bracket. The company also expanded the offering from its original plan of 42.86 million shares.
Trading under the symbol XE on the Nasdaq, the stock launched at $30.11. Throughout the trading session, shares reached a peak of $31.33.
Investor appetite proved overwhelming, with subscription demand surpassing supply by over 15 times. Approximately one-third of institutional buyers received no share allocation. Company leadership played an active role in determining share distribution.
The offering generated approximately $1.02 billion in total proceeds, substantially higher than previous projections of roughly $700 million.
Based on the company’s outstanding equity, the market debut established X-Energy’s valuation near $12 billion. Alternative calculations positioned the figure closer to $9 billion.
Regulatory documents revealed that Ark Investment Management could acquire as much as $105 million in IPO shares.
The underwriting syndicate included JPMorgan Chase, Morgan Stanley, Jefferies Financial Group, and Moelis & Co.
Technology and Commercial Backing
X-Energy focuses on SMR design and advanced nuclear fuel production. The company’s reactors utilize Triso fuel — tristructural isotropic uranium particles approximately the size of poppy seeds — engineered to operate at higher temperatures and for extended periods compared to traditional fuel sources.
CEO Clay Sell articulated the company’s vision for standardized nuclear energy deployment. “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 has also taken an ownership position in X-Energy.
Regulatory approval for the company’s inaugural reactor is anticipated this year, with construction planned in Texas for Dow. The facility is expected to become operational in the early 2030s.
Further development projects are in the pipeline for Washington state, serving Amazon’s energy requirements.
Financials and Ownership
X-Energy remains in pre-commercial operations. The company reported net losses of roughly $390 million on $94 million in revenue last year, not including grant funding. The year before, net losses totaled $126 million on $84 million in revenue.
Losses have expanded as the organization increases development expenditures in preparation for its initial reactor deployment.
Company founder and chairman Kamal Ghaffarian maintains control of 61% of Class B shares. Entities affiliated with Ares Management Corp. possess another 26%.
Shares concluded the inaugural trading session significantly above the offering price, with XE finishing approximately 27% higher by market close.
