Key Points (Barron's summary): - Westinghouse Electric plans to go public as the nuclear developer benefits from a surge of interest and government support for new reactors. - Owned by Brookfield Asset Management and Cameco, Westinghouse plans to start construction on 10 new reactors in the U.S. by 2030. - Westinghouse's AP 1000 reactor is the most advanced U.S. design on the market.
Westinghouse Electric, the nuclear developer behind America's most advanced large reactor design, plans to go public, the company said on Friday.
Westinghouse is one of the few nuclear developers that actually makes money, so its IPO could be a blockbuster, potentially valuing the company at tens of billions of dollars. Several upstart reactor developers have been valued in the billions of dollars despite having no approved designs or significant revenue.
Westinghouse is benefiting from a surge of interest and government support for new reactors. The company, now owned by Brookfield Asset Management and Canadian uranium miner Cameco, says it plans to start construction on 10 new reactors in the U.S. by 2030.
The Trump administration has tried to help the cause, reaching a preliminary agreement with Japan to finance up to $80 billion worth of new Westinghouse reactors as part of a trade deal. As part of the arrangement, the U.S. government could get a stake in Westinghouse, worth 20% of any cash distributions exceeding $17.5 billion, or warrants worth up to 20% of the value of the stock if Westinghouse goes public.
The Japan deal remains in limbo, so the government's stake is up in the air too. The U.S. government has also offered companies $17.5 billion worth of loans for utilities and others to buy equipment for Westinghouse reactors.
Westinghouse's AP 1000 reactor is the most advanced U.S. design on the market.
Two AP 1000s were completed in Georgia this decade, though no more are under construction yet in the U.S. The Georgia reactors came in nearly $20 billion over budget and years behind schedule.
Westinghouse went bankrupt during the process, due largely to the cost overruns. The company says it's since simplified its business model, leaving construction of the plants to others while making money by licensing the design and offering services.
Even though the U.S. isn't currently building reactors, Westinghouse is making money off overseas reactors.
Cameco, which owns 49% of the company, offered some details about Westinghouse in its financials. Its share of Westinghouse's revenue in 2025 was 3.46 billion Canadian dollars ($2.47 billion U.S. dollars), which was up 20% year over year.
By comparison, BWX Technologies, another nuclear provider, reported $2.35 billion in revenue in 2025. It's valued at $15 billion.
