X-energy Upsizes IPO, Sets Pricing for Nasdaq Listing

X-energy, a leader in advanced nuclear reactor and fuel technology, recently announced the pricing of its expanded initial public offering (IPO). According to the latest announcement, the company will offer 44,254,659 Class A ordinary shares in a public offering and has granted underwriters a 30-day over-allotment option to purchase up to an additional 6,638,198 shares. The listing is expected to begin trading on the Nasdaq Global Select Market, with the closing date subject to customary conditions.

X-energy specializes in high-temperature gas-cooled reactor (HTGR) technology and next-generation nuclear fuel. Its small modular reactor (SMR) design offers significant advantages in safety, cost-efficiency, and operational flexibility. The company previously filed its S-1 registration statement confidentially with the U.S. Securities and Exchange Commission (SEC), laying the legal groundwork for this IPO. The expanded offering size reflects strong market demand for clean energy technologies, particularly in the advanced nuclear sector.

Analysts note that as global demand for low-carbon baseload power grows, X-energy’s listing will inject critical capital into its commercialization efforts. Proceeds are expected to be used to advance reactor design certification, fuel manufacturing facility construction, and early project deployment. If completed as planned, X-energy’s IPO could become one of the most notable nuclear energy listings in 2026.
