4/24/2026, 9:23:24 PM
IPO Overview and Financial Highlights
On April 23 2026, X-Energy priced its initial public offering at $23 per share, selling 44.3 million Class A common shares and raising roughly $1.02 billion in gross proceeds before underwriting discounts. The offering was upsized beyond the $16-$19 range and includes a 30-day option for underwriters to purchase an additional 6.6 million shares. Trading on Nasdaq under ticker “XE” begins April 24, with the offering slated to close April 27. Lead book-runners are J.P. Morgan, Morgan Stanley, Jefferies and Moelis & Company.
Company Background and SMR Technology
Founded in 2009, X-Energy develops small modular reactors (SMRs) and advanced nuclear fuel. Its flagship Xe-100 reactor uses helium as a coolant, a design intended to improve safety and shorten construction time relative to conventional large-scale reactors that can take years to build. The company previously pursued a SPAC merger with an Ares-backed blank-check firm in 2023, but cancelled the plan citing unfavorable market conditions.
Amazon Investment and Strategic Rationale
In 2024, Amazon invested approximately $500 million in X-Energy to accelerate SMR deployment. The investment aligns with Amazon’s objective of securing reliable, carbon-free electricity for its expanding AI-driven data center portfolio, which requires substantial, continuous power. By backing a domestic SMR developer, Amazon seeks to diversify its energy sources and mitigate exposure to grid volatility.
Market Context and Investor Appetite
The IPO follows a brief market slowdown in March 2024, driven by volatility linked to Middle East tensions and a broader technology sell-off. Renewed investor interest in nuclear power reflects rising electricity demand, especially from hyperscalers operating energy-intensive AI and cloud services. X-Energy’s pricing above the marketed range signals strong demand for clean-energy technologies that promise low-carbon baseload power.
Official Statements
According to the company’s statement, the IPO was priced at $23 per share, with 44.3 million shares sold and a 30-day option for underwriters to purchase an additional 6.6 million shares. Amazon’s investment announcement emphasized the goal of obtaining reliable, carbon-free power for its AI-driven data centers.
