Social media giant Twitter is all set to reshuffle their organization which will prompt resignation from three top executives.  It also means a new chief marketing officer and two board members, a source confirmed on Sunday.

The transformation will mark the biggest change in leadership since the return of Jack Dorsey as chief executive. Twitter Media Head Katie Jacobs Stanton along with product head Kevin Weil and Engineering Division head Alex Roetter are all ready to quit the company. Twitter’s video streaming service Vine’s head Jason Toff as well as Business Development Leader Jana Messerschimidt may also quit.

Technology news website Re/Code reported the news first. It said that Twitter was expected to make board changes, while the New York Times reported addition of two new board members into the group. According to the DNA, some executives seem to resign under pressure, while others have voluntarily decided to leave.  Twitter has long been struggling to attain a considerable position on the Wall Street Index.

The source confirmed the company will announce the changes on Monday, but Twitter declined to comment on the matter on Sunday. According to Reuters, Weil, Stanton and Roetter are among the highest officials to quit in recent months. But prior to this, several executives from the company left, including co-founder Dorsey who rejoined Twitter in July and held the position of the CEO there.

The company stocks dipped to 50 percent since Dorsey’s return and are presently trading below its IPO price. The source familiar with the matter said that the CEO was still not ready to provide a detailed plan of what the company intends to do differently.

Business analysts have opined that Twitter has been unsuccessful to show any swing in its growth chart despite the speedy product roll-outs implemented by Dorsey, which was a major concern at the moment.
