Twitter has struck a deal to keep Jack Dorsey as CEO, after an activist hedge fund recently agitated for leadership change at the company.

The deal will include a $2 billion share buyback program and give the hedge fund, Elliott Management, a seat on Twitter’s board of directors, according to a press release.

Elliott, which has invested in and advocated for changes at many major companies, had recently pushed for changes at the company. Last week, Dorsey said he was re-evaluating his plans to spend more time in Africa, though he cited the new coronavirus outbreak as the reason.

Technology investment firm Silver Lake will be investing $1 billion in Twitter as part of the agreement, and Silver Lake will also receive a board seat. The board will also work toward finding a third new board member, according to the press release.

“Silver Lake’s investment in Twitter is a strong vote of confidence in our work and our path forward,” Dorsey said in the press release. “They are one of the most respected voices in technology and finance and we are fortunate to have them as our new partner and as a member of our Board.”

Dorsey was named CEO of Twitter in 2015 at a time when the company was struggling to turn a profit and had been easily surpassed in terms of users and revenue by other tech companies including Facebook.

The company has since been able to show some user growth and turn a profit. The company has also made a variety of changes to its platform and its user policies that have helped limit hate speech and misinformation on its platform.

But Dorsey’s leadership has been the subject of some criticism. He is also the CEO of the payments company Square and lives a lifestyle not typical of most chief executives. In 2018, he took a trip to Myanmar to participate in a 10-day silent meditation session.

Elliott’s move to pressure Dorsey, however, was met with a show of support from employees who organized around a hashtag to keep him as CEO.
