X-Energy Inc. kicked off its public trading journey Friday with an impressive performance, seeing shares climb 36% during its initial session following a heavily oversubscribed offering that brought in over $1 billion.
X-Energy, Inc. Class A Common Stock, XE
The Maryland-headquartered developer of small modular nuclear reactors (SMRs) sold 44.25 million shares at $23 apiece — exceeding its projected $16 to $19 pricing bracket. The company also expanded the offering size beyond its original plan of 42.86 million shares.
Trading under ticker symbol XE on the Nasdaq, shares debuted at $30.11 and reached an intraday peak of $31.33.
Investor appetite proved overwhelming, with subscription levels topping 15 times the available allocation. Approximately one-third of institutional participants walked away empty-handed. Company leadership played an active role in determining final share distributions.
The offering generated roughly $1.02 billion in total capital, significantly outpacing initial projections of approximately $700 million.
Calculated on outstanding equity, the first-day valuation pushed X-Energy’s market capitalization near $12 billion, though alternative calculations suggested figures closer to $9 billion.
Regulatory documents revealed that Ark Investment Management indicated potential purchases reaching $105 million of IPO shares.
JPMorgan Chase, Morgan Stanley, Jefferies Financial Group, and Moelis & Co. served as lead underwriters for the transaction.
Core Technology and Strategic Partnerships
X-Energy specializes in SMR development and produces next-generation nuclear fuel. The company’s reactor systems utilize Triso fuel — tristructural isotropic uranium particles approximately the size of poppy seeds — engineered to operate at higher temperatures and extended durations compared to traditional nuclear fuel.
CEO Clay Sell articulated the company’s vision of standardizing nuclear power generation. “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 the enterprise.
Regulatory approval for X-Energy’s inaugural reactor is anticipated this year, with construction slated for a Texas facility serving Dow. The plant is expected to become operational in the early 2030s.
Further developments are in the pipeline for Washington state locations supporting Amazon’s energy requirements.
Financial Position and Shareholder Structure
X-Energy remains in the pre-revenue phase from a commercial operations standpoint. The company reported net losses of roughly $390 million against $94 million in revenue last year, not including government grants. The year prior showed net losses of $126 million on $84 million in revenue.
Loss figures are expanding as the organization accelerates development initiatives in preparation for its first reactor launch.
Company founder and chairman Kamal Ghaffarian maintains control of 61% of Class B voting shares. Entities affiliated with Ares Management Corp. possess another 26%.
The stock concluded its inaugural trading session substantially above the offering price, with XE finishing approximately 27% higher by market close.
