Twitter Inc.'s board is a considering a shakeup that may involve the departure of former Chief Executive Officer Dick Costolo, people with knowledge of the matter said.
The changes, which could be announced when the company names a permanent CEO, are aimed at making the group of directors more diverse, said the people, who asked not to be identified because the deliberations aren't public. The board may expand or be shuffled to include directors from different backgrounds, such as minorities and those with experience in adjacent industries, the people said. Any changes may also address the fact that the current board includes three former CEOs - Jack Dorsey, Ev Williams and Costolo - an issue that would make it difficult for any new CEO to run the company.
