General Fusion begins trading on Nasdaq, becomes first nuclear fusion company to go public

General Fusion has become the first company solely focused on fusion power to go public.

The Richmond, BC-based company made its Nasdaq debut on Monday morning, days after shareholders voted to merge the private company with the publicly traded special purpose acquisition company (SPAC) Spring Valley Acquisition Corp. III (Spring Valley). At closing, Spring Valley was redomiciled in BC.

After completing the transaction, General Fusion said in a news release that it is entering the public markets with about $150 million USD ($212 million CAD) in cash. Shares are now trading under the ticker $GFUZ, and were sitting at $12.80 USD at market open.

This milestone comes weeks after Canada highlighted fusion as one of the innovative forms of power the federal government intends to support.

The milestone came weeks after Canada launched a national nuclear energy strategy, which listed fusion as one of the innovative forms of power the federal government intends to support.

“Canada’s status as a Tier One nuclear nation was built on innovation: the CANDU reactor, successive research reactor deployments, and the pioneering of medical isotopes,” the strategy reads. “Sustaining that status requires continued investment in … next-generation technologies.”

The global race for commercial fusion power—which would harness energy from similar reactions to those that power the sun—has captured players from around the globe, from national labs to private companies like General Fusion. The technology, if proven commercially viable, offers a promise of abundant, fossil-fuel-free power that could help supply rising electricity demands.

General Fusion CEO Greg Twinney had previously said that he joined the company for two reasons: to make the world a better place for his kids, and to realize potentially enormous financial returns.

General Fusion is still pre-revenue and pre-commercialization, with years to go before it might possibly be in a place to bring its tech to market. Since its founding in 2002, the company has raised $400 million, but has yet to demonstrate fusion power that generates more electricity than it costs to produce. Last year, the company laid off staff and issued a public plea for further investment.

The company has also signed an agreement with energy infrastructure firm Renexia to begin exploring sites for a possible fusion power plant in Italy, with the goal of deploying its magnetized target fusion technology in a commercial plant by 2035.

US-based TAE Technologies, another company focused on developing fusion, reportedly aims to go public later this year.

Chris Gadomski, lead analyst for nuclear at Bloomberg New Energy Finance, told BetaKit in an interview that General Fusion successfully going public is “a great development” for the company and potentially the broader fusion industry.

At the same time, Gadomski noted that the $150 million General Fusion has today is “a drop in the bucket” of what it will need to attain its broader ambitions, including that 2035 target. Gadomski highlighted that many of General Fusion’s competitors have raised much larger sums to date.

Gadomski also highlighted that going public “has not necessarily been a good thing” for many fission companies, which are now trading down significantly from their highs. Given General Fusion’s still long path to commercialization and the volatile global energy market amid the Iran war, he is curious to see how well it is received by public market investors.

Seeing as fusion power is “very, very challenging,” and requires “a lot” of time and capital to develop, “Hopefully, this will be a first step of many public offerings that General Fusion will be able to do to provide the cash it needs to be successful,” Gadomski said.
