X-Energy Inc. experienced a robust first trading session on Friday, with shares climbing 36% following a heavily oversubscribed initial public offering that generated more than $1 billion in capital.
X-Energy, Inc. Class A Common Stock, XE
The Maryland-based developer of small modular nuclear reactors (SMRs), headquartered in Rockville, offered 44.25 million shares at $23 apiece — exceeding its originally marketed $16 to $19 price band. The company also expanded the offering size from a previous target of 42.86 million shares.
Trading under the symbol XE on the Nasdaq, the stock launched at $30.11 and reached an intraday peak of $31.33.
Demand for the offering was extraordinary, with subscription levels exceeding available shares by more than 15-fold. Approximately one-third of institutional investors received no allocation whatsoever. Company leadership played an active role in determining share distribution.
The offering generated approximately $1.02 billion in gross proceeds, significantly surpassing initial projections of roughly $700 million.
Using the total share count, X-Energy’s opening market capitalization approached $12 billion, though some analyses suggested a figure nearer to $9 billion.
Regulatory documents revealed that Ark Investment Management could acquire up to $105 million in IPO shares.
The underwriting syndicate included JPMorgan Chase, Morgan Stanley, Jefferies Financial Group, and Moelis & Co. as lead managers.
Advanced Reactor Technology and Strategic Partnerships
X-Energy specializes in SMR design and produces next-generation nuclear fuel. The company’s reactor technology utilizes Triso fuel — tristructural isotropic uranium particles roughly the size of poppy seeds — engineered to operate at higher temperatures and achieve longer burn cycles than traditional nuclear fuel.
CEO Clay Sell articulated the company’s vision of standardizing nuclear energy production. “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 arrangements with Amazon, Dow Inc., and Centrica. Amazon has also taken an ownership stake in the business.
Regulatory approval for X-Energy’s initial reactor is anticipated this year, with construction planned in Texas for Dow. The facility is expected to commence operations in the early 2030s.
Further reactor installations are in development in Washington state for Amazon.
Financial Performance and Shareholder Structure
X-Energy remains in the pre-commercial stage. Last year, the company recorded net losses of roughly $390 million on $94 million in revenue, excluding government grants. The year before showed a net loss of $126 million against $84 million in revenue.
Losses have expanded as the company accelerates development efforts in preparation for its initial reactor deployment.
Founder and chairman Kamal Ghaffarian maintains control of 61% of the company’s Class B voting shares. Entities affiliated with Ares Management Corp. own another 26%.
XE concluded its inaugural trading session significantly above its IPO price, finishing the day approximately 27% higher.
