Strong Market Debut and Oversubscribed Offering
X-Energy priced its IPO at $23 per share, exceeding its marketed range of $16 to $19. The stock opened at $30.11 and reached an intraday high above $31 during early trading. Demand exceeded supply by more than fifteen times, indicating strong institutional participation.
The company raised approximately $1.02 billion, surpassing earlier expectations near $700 million. Major banks including JPMorgan, Morgan Stanley, Jefferies, and Moelis led the offering. The strong debut placed X-Energy among the largest nuclear-related public listings on record.
The company achieved a valuation near $12 billion based on outstanding shares. However, some estimates placed the market capitalization closer to $9 billion. The listing marks a significant milestone for advanced nuclear developers entering public markets.
Technology Model and Strategic Partnerships
X-Energy focuses on small modular reactors designed for electricity generation and industrial heat applications. Its Xe-100 reactor produces 80 megawatts and can scale to 960 megawatts through modular deployment. The design uses high-temperature gas cooling with TRISO fuel technology.
TRISO fuel consists of uranium kernels coated with carbon and silicon layers for enhanced safety. The design withstands higher temperatures and reduces meltdown risks compared to traditional light water reactors. The company also plans to supply nuclear fuel from its Tennessee fabrication facility.
X-Energy has secured agreements with Amazon, Dow, and Centrica for future deployments. The company targets over 11 gigawatts of pipeline capacity through these partnerships. It also plans a 320-megawatt project with Energy Northwest as part of its long-term expansion.
Growth Plans and Financial Position
X-Energy expects to deliver its first commercial reactor in the early 2030s. The company submitted a construction permit application with Dow for a Texas project currently under regulatory review. It also plans to deploy up to five gigawatts with Amazon across the United States by 2039.
The company follows a licensing model rather than owning and operating nuclear plants. This approach allows faster scaling while reducing capital intensity and operational risk. The company aims to generate revenue from both technology licensing and fuel sales.
X-Energy reported a net loss of about $390 million on revenue of $94 million last year. The company continues to invest heavily in development and regulatory processes. Ownership remains concentrated, with founder Kamal Ghaffarian holding a majority voting stake.
