Tesla, Inc.

Elon Musk has sold 4.4 million shares of Tesla stock worth roughly $4 billion, most likely to help fund his purchase of Twitter.

Musk reported the sale in a filing with the Securities and Exchange Commission on Thursday. The shares were sold over the past few days, at prices ranging from $872.02 to $999.13.

The board of Twitter has agreed to sell the social network to billionaire Elon Musk for $44 billion or $54.20 per share, which is nearly 38% above the closing price of Twitter shares on the 1st of April - before Musk revealed that he had bought about a 9 percent stake in social media.

Elon Musk reached an agreement to buy Twitter for roughly $44 billion on Monday, promising a more lenient touch to policing content on the social media platform where he, the world's richest person, promotes his interests, attacks critics and opines on a wide range of issues to more than 83 million followers.

Twitter is reconsidering Elon Musk's buyout proposal, with discussions between the two camps ongoing Sunday, The Wall Street Journal reported, after the billionaire said Thursday he had secured the necessary funding.

"Twitter is taking a fresh look at the offer and is more likely than before to seek to negotiate," the business daily reported, citing sources familiar with the matter.

Tesla CEO Elon Musk has lined up $46.5 billion in financing for a possible hostile takeover of Twitter and is "exploring" a direct tender offer to shareholders, according to a securities filing released on April 21.

Twitter has dropped a major roadblock in front of Elon Musk's effort to take over the company, leaving investors to wonder about the mercurial Tesla CEO's next move.

Twitter's board of directors has unanimously adopted a "poison pill" defense in response to Tesla CEO Elon Musk's proposal to buy the company for more than $43 billion and take it private.

A 2018 tweet posted by Elon Musk in which he claimed to have secured the funding to take Tesla private was deemed "false and misleading" by a judge, according to documents filed by investors suing his electric car company.

Even for the richest person on the planet, buying Twitter was always going to be a challenge - a highly complex financial transaction now made even trickier by a defensive "poison pill" move from the platform's board.

Elon Musk is offering to buy Twitter, just days after the Tesla CEO said he would no longer be joining the social media company's board of directors.
