X-Energy, Inc. Class A Common Stock, XE
The Maryland-headquartered small modular reactor (SMR) specialist sold 44.25 million shares at $23 apiece — surpassing its initial pricing guidance of $16 to $19. The company also expanded the offering size from a previously planned 42.86 million shares.
Trading commenced at $30.11 on the Nasdaq exchange using the symbol XE. Throughout the session, the stock reached an intraday high of $31.33.
Demand for the offering exceeded supply by over 15-fold. Approximately one-third of institutional bidders received no share allocation whatsoever. Company leadership played a significant role in determining final distribution.
The offering generated total proceeds of roughly $1.02 billion, significantly outpacing earlier projections of approximately $700 million.
Calculated on outstanding equity, the market debut positioned X-Energy’s valuation near $12 billion. Alternative calculations suggested a range closer to $9 billion.
Ark Investment Management disclosed in regulatory documents that it might acquire as much as $105 million in IPO shares.
The underwriting syndicate included JPMorgan Chase, Morgan Stanley, Jefferies Financial Group, and Moelis & Co.
Innovation and Strategic Partnerships
X-Energy develops small modular reactors and produces next-generation nuclear fuel. The company’s reactor technology utilizes Triso fuel — tristructural isotropic uranium particles comparable in size to poppyseeds — engineered to operate at higher temperatures and maintain longer burn cycles than traditional fuel.
CEO Clay Sell explained the company’s vision is to deliver predictable, standardized nuclear energy solutions. “We want to make nuclear boring,” he stated. “We can build this over and over and over again. That’s the way you get costs down.”
The firm has secured commercial contracts with Amazon, Dow Inc., and Centrica. Amazon has also taken an equity position in X-Energy.
X-Energy anticipates obtaining regulatory approval this year for its inaugural reactor, scheduled for construction in Texas to serve Dow. The facility is expected to commence operations in the early 2030s.
Further development projects are in the pipeline for Washington state to support Amazon’s energy needs.
Financial Performance and Shareholder Structure
X-Energy currently operates without substantial commercial revenue. The company recorded a net loss of roughly $390 million on $94 million in revenue last year, not including government grants. The preceding year showed a net loss of $126 million on $84 million in revenue.
The expanding losses reflect accelerated development spending as the company prepares for initial reactor deployment.
Company founder and chairman Kamal Ghaffarian maintains control of 61% of Class B shares. Affiliates of Ares Management Corp. possess another 26%.
The stock concluded its inaugural trading session substantially above the IPO price, with XE finishing approximately 27% higher by market close.
