On 14 April, Tesla and SpaceX CEO Elon Musk made a final unsolicited bid for Twitter at US$54.20/share. The bid was made after Musk had acquired 9.2% of its shares and declined a seat on the company’s board. However, since then, Twitter has adopted a poison pill approach to prevent him from taking over the company. The details of poison pill approaches differ by company, but it is designed to give a company’s board the option to flood the market with so much newly created shares that a takeover becomes prohibitively expensive.
