Twitter is adding Elon Musk to its board of directors after he bought a 9% stake in the company

The social media company announced Tuesday morning that Musk is joining their board.

Through conversations with Musk, it became clear to us that he would bring great value to our Board.

In a possible nod to those improvements, Musk asked his 80 million followers if they wanted an edit button on the service.

The consequences of the poll will be important, and the CEO of the micro-blogging site got in on it. Please vote carefully.

Musk disclosed a 9.2% stake in the company earlier this week. The investment made him the largest shareholder.

Following the announcement, shares of the micro-blogging site popped more than 5%.

The terms of Musk's appointment to the board were detailed in an SEC filing on Tuesday.

He is to begin serving as soon as possible, following a background check and other formality, with a term that expires in 2024. As part of his appointment, Musk isn't allowed to become the beneficial owner of more than 14.9% of the company's common stock, which is to say that, while he serves.
