Devin Nunes Departs Trump Media After 4 Years as C.E.O.

President Trump’s social media company, which has consistently lost money and struggled with a flagging share price, announced Tuesday that it was replacing Devin Nunes as its chief executive officer.

The announcement offered no reason for the sudden departure of Mr. Nunes, a former Republican congressman from California. Mr. Trump had tapped him to run the company, Trump Media & Technology, in late 2021.

The announcement was made in a news release by the president’s eldest son, Donald Trump Jr., who is a company board member and oversees a trust that controls his father’s 115-million-share stake in Trump Media. President Trump is not an officer or director of the company.

Mr. Nunes said in a statement on Truth Social, which is Trump Media’s flagship product, that it was an “appropriate time” for a new leader with experience in media and mergers to “steer Trump Media through its current transition phase.”

Trump Media has incurred hundreds of millions in losses, and its shares have performed poorly since the company went public by completing a merger with a cash-rich special purpose acquisition company, or SPAC, in March 2024. The stock, which ended its first day of trading around $58 a share, closed Tuesday at $9.82.

Shares of Trump Media trade under the symbol DJT, which are President Trump’s initials. Truth Social has emerged as the main social media platform for Mr. Trump to communicate his policy decisions and opinions to the world.

Last year, Trump Media took in $3.7 million in revenue and recorded a $712 million net loss.

In December, Trump Media announced a plan to merge with TAE Technologies, a fusion power company. The all-stock deal, which was valued at $6 billion at the time, would create one of the first publicly traded nuclear fusion companies.

Trump Media said in February that it was considering spinning off its Truth Social platform in a merger with another cash-rich SPAC, Texas Ventures Acquisition III Corp.

Mr. Nunes is being replaced on an interim basis by Kevin McGurn, who has been an adviser to Trump Media since the end of 2024. Mr. McGurn, a former executive at Hulu, the streaming service, was listed in a recent regulatory filing as the chief executive of Texas Ventures.

The Trump Media release announcing the management change provided no update on the merger with TAE Technologies or the proposed SPAC deal for Truth Social.
