Elon Musk will join Twitter’s board of directors after taking a 9.2% stake in the social media company.

“Through conversations with Elon in recent weeks, it became clear to us that he would bring great value to our Board,” CEO Parag Agrawal said in a tweet. “He’s both a passionate believer and intense critic of the service which is exactly what we need on Twitter, and in the boardroom, to make us stronger in the long-term,” Agrawal added. Former chief Jack Dorsey praised the move, saying in a tweet that Musk “cares deeply about our world and Twitter’s role in it.” “I’ve wanted Elon on the board for a long time,” Dorsey later added.

Musk’s term is set to expire in 2024, according to a filing with the SEC. For his entire board term or 90 days after, Musk cannot be the beneficial owner of more than 14.9% of the company’s common stock outstanding. […] After he was named to the board, Musk on Tuesday teased he would push for adjustments to the product. “Looking forward to working with Parag & Twitter board to make significant improvements to Twitter in coming months!” Musk said in a tweet.
