Elon Musk last week bought Twitter Inc. for $44 billion with the help of a Wall Street bank loan and shareholders who agreed to roll over their interest in the social media service in exchange for a stake in the new private company.

That means Twitter, whose shares listed last week after nearly a decade as a public company, has a new lineup of top investors.

Prince Alwaleed bin Talal

Regulatory filings show the Saudi crown prince transferred about 35 million Twitter shares through Kingdom Holding Co., worth about $1.9 billion at a sale price of $54.20 per share. This made him the “second largest investor” in the new parent company.

Alwaleed quickly backed Musk’s plans to acquire Twitter, saying in May that Musk would be “an excellent leader” for the social media company.

Jack Dorsey

The Twitter co-founder and former CEO owns more than 18 million shares, or about 2.4% of the public company, at a merger price worth about $978 million. That gave him shares in Musk’s X Holdings Inc., which controls Twitter.

After Musk first agreed to buy Twitter in April, Dorsey lamented that the company was “owned” by Wall Street and said taking it private was the “right” first step.

Qatar Investment Authority

A subsidiary of Qatar’s sovereign wealth fund contributed $375 million in exchange for shares in Musk’s holding company.

The Bloomberg Billionaires Index estimates that shares rolled over from Twitter stock have fallen about 40 percent in value since Musk made his offer in April, based on the index’s decline in the social-media company’s shares.
