Trump Media & Technology will merge with a fusion power company in an all-stock deal that the companies said Thursday is valued at more than $6 billion.

Devin Nunes, the Republican congressman who resigned in 2021 to become the CEO of Trump Media, will be co-CEO of the new company with TAE Technologies CEO Michl Binderbauer.

Shares of Trump Media & Technology, the parent company of President Donald Trump`s Truth Social media platform, have tumbled 70% this year but jumped 20% before the opening bell Thursday.

TAE is a private company and the merger with Trump Media would create one of the first publicly traded nuclear fusion companies.

"We`re taking a big step forward toward a revolutionary technology that will cement America`s global energy dominance for generations," Nunes said in a prepared statement.

TAE focuses on nuclear fusion, a technology that combines two light atomic nuclei to form a single heavier one. It releases enormous amount of energy, a process that occurs on the sun and other stars, according to the United Nation`s International Atomic Energy Agency.

TAE and Trump Media shareholders will each own approximately 50% of the combined company.

The companies say the transaction values each TAE common stock at $53.89 per share.

At closing, Trump Media & Technology Group will be the holding company for Truth Social and TAE, along with its subsidiaries TAE Power Solutions and TAE Life Sciences.
