Amazon-backed X-energy files to raise up to $800M in IPO

Nuclear startup X-energy began its capitalist roadshow Wednesday arsenic it works toward its IPO, mounting its people terms betwixt $16 and $19 per share, according to documents filed with the U.S. Securities and Exchange Commission. If it lists astatine the precocious end, the startup could nett $814.3 million.

X-energy and its peers person been riding a renewed question of involvement successful fission powerfulness arsenic request for energy has surged connected the backmost of AI information centers and society-wide electrification. 

Amazon is 1 of X-energy’s biggest backers. The tech elephantine led a $500 cardinal Series C-1 circular and has pledged to bargain as overmuch arsenic 5 gigawatts of atomic powerfulness from the institution by 2039.

The IPO is definite to travel arsenic a alleviation to X-energy’s investors, which person enactment astir $1.8 cardinal into the company, according to PitchBook. The startup had antecedently attempted to spell nationalist via reverse merger with a peculiar intent acquisition company, but the 2 parties canceled the deal successful 2023 arsenic the SPAC craze petered out.

X-energy’s reactor is what’s known arsenic a high-temperature, gas-cooled reactor. Inside, uranium encased successful spheres of ceramic and c is cooled by helium gas. The state past transfers vigor to a steam turbine loop to make electricity. The substance design, known arsenic TRISO, is expected to beryllium safer than erstwhile substance arrangements, though it’s not wide utilized today.

The startup said successful its SEC filing that it’s already embroiled successful a patent quality with different institution that precocious went bankrupt. Ultra Safe Nuclear Corporation (USNC) went bankrupt successful 2024, and its assets were purchased successful bankruptcy to signifier Standard Nuclear. X-energy alleges that USNC infringed connected its substance fabrication patents and that the substance hasn’t been resolved to its restitution during the people of the bankruptcy proceedings.

Outside of China, improvement of caller atomic reactors has each but stalled, stymied by delays and outgo overruns. A caller breed of startups hopes that by shrinking reactors, they’ll beryllium capable to flooded immoderate of the challenges that person beset accepted designs.

None of the tiny modular reactor startups person built a powerfulness works yet, though respective are racing to conscionable a deadline of July 4 acceptable by the Trump administration.

While galore mightiness miss the arbitrary deadline, they’re inactive apt to execute criticality, the infinitesimal erstwhile fission reactions go self-sustaining.

But the roadworthy from criticality to profitable powerfulness plants is apt to beryllium long. Mass manufacturing tin assistance bring costs down, but it usually takes around a decade for the process to commencement paying dividends. What’s more, the fig of reactors these companies are readying to physique mightiness beryllium much than different companies person attempted, but it mightiness not beryllium precocious capable to reap the existent benefits of wide manufacturing.

X-energy expects that by the clip its reactor accumulation techniques are mature — what experts telephone “Nth-of-a-kind” — it volition beryllium capable to bring costs down by 30% comparative to the first-of-a-kind. Investors should wage adjacent attraction to however overmuch that archetypal reactor costs. It could marque oregon interruption the company’s prospects.
