Twitter has launched a poison pill takeover defence to fend off a $43bn hostile bid from billionaire Tesla chief executive Elon Musk.
In the first sign that the social media company plans to fight Musk’s bid, Twitter said on Friday that its board of directors had unanimously adopted a year-long shareholder rights plan to “enable all shareholders to realise the full value of their investment in Twitter”.
The board’s aggressive move, designed to block Musk from building a greater than 15 per cent stake in the open market, is likely to end the South African-born entrepreneur’s hopes of buying the social media company.
It comes as US private equity group Thoma Bravo has also expressed interest in taking Twitter private in what would be a rival bid to Musk’s, although sources said it was at a very preliminary stage and no offer has been made.
Musk said this week that his offer was “best and final” adding that “if it is not accepted, I would need to reconsider my position as a shareholder”.
Under Twitter’s plan, existing shareholders will be able to buy shares at a discount if anyone acquires more than 15 per cent without board approval, diluting an unwelcome bidder.

Musk offered $54.20 a share in cash for Twitter, valuing the company at $43.4bn, days after he took a 9 per cent stake in the company to become one of its largest shareholders.
Twitter’s board is concerned that if Musk built a stake worth more than 15 per cent he could indirectly wield significant power over the direction of the company even without an executive or directorship role.
The only way for him to take over Twitter now is through a mutually agreed deal, which would need to carry a significantly higher price, said a person close to the company’s board.
Poison pills were developed as a defence strategy in the 1980s to protect companies from corporate raiders, and were widely criticised as a way for a company’s managers to entrench themselves against attack. Subsequent legal challenges reduced some of their effectiveness, and most academic studies have shown that while poison pills slow an unwanted takeover bid, they do not usually prevent eventual agreement after a negotiation.
Twitter said the plan could reduce the likelihood that a hostile bidder “gains control of Twitter through open market accumulation without paying all shareholders an appropriate control premium”, as well as slow any bid.
“The Rights Plan does not prevent the Board from engaging with parties or accepting an acquisition proposal if the Board believes that it is in the best interests of Twitter and its shareholders,” it added.
The plan expires on April 23 2023, it said.
After his shareholding was announced last week, Musk reached a preliminary agreement with the company to join its board of directors, only to reverse course on Monday without explanation.
Musk then announced his offer on Thursday in a regulatory filing in which he said he would unlock the company’s potential to be “the platform for free speech around the globe”.
The offer represents a 38 per cent premium to Twitter’s share price since April 1, three days before his stake became public, although it is still 26 per cent below its 12-month high.
Musk did not address the poison pill counterattack publicly on Friday, instead thanking his fans on Twitter for their “support” after they voted in favour of him buying the company in an online poll run by a bitcoin newsletter.
