Twitter’s Chief Executive Officer Jack Dorsey will step down from his role and a successor has been lined up, Reuters reports.

The company’s board has been preparing for Dorsey’s departure since last year, the source said.

The news comes as Twitter has accelerated the pace of its product innovation over the past year to compete with social media rivals such as Facebook Inc (FB.O) and TikTok, and to reach its goal of doubling annual revenue by 2023.

Twitter was not immediately available for comment.

Shares of the microblogging platform surged 9% in early trading, while those of digital payments firm Square Inc (SQ.N), of which Dorsey is also chief executive, were up 3%.

Trading in the shares was then suspended ahead of an expected announcement.

In his latest tweet on Nov. 28, Dorsey said: “I love Twitter”. The “likes” on that tweet surged to more than 54,000 on Monday.

In early 2020, Dorsey faced calls from Elliott Management Corp to step down, after the hedge fund argued THAT he was paying too little attention to Twitter while also running payments processing company Square Inc.

Dorsey fended off the pressure by giving Elliott and its ally, buyout firm Silver Lake Partners, seats on Twitter’s board.
