Twitter Inc  has announced the appointment of Mimi Alemayehou to the Company's Board of Directors as a new independent director, to replace Elliott Management partner Jesse Cohn, after the activist hedge fund helped create a blueprint for changes that led to a doubling of the social media firm's share price.

Alemayehou will join the board immediately and Cohn will step down, the company said in a release. Elliott, one of Twitter's top 20 investors, will continue to engage with senior management and the board through an "information sharing and engagement agreement," Twitter said.

Cohn, who runs the USD40 billion hedge fund’s U.S. activism practice, was appointed to the Twitter board in March 2020, as part of a deal with the social media company to let Chief Executive Jack Dorsey keep his job and allow Elliott to take a board seat.

Cohn joined the board alongside Silicon Valley tech investor Egon Durban, co-chief of private equity company Silver Lake. Elliott had previously pushed to remove Dorsey after criticizing him for holding the CEO position at both Twitter and mobile payments company Square Inc. After a long period of languishing performance, in which Dorsey admitted Twitter had been slow to innovate and introduce new features, the platform has more recently made a slew of announcements to attract more users and advertisers.
