Elon Musk struck a deal on Monday to buy Twitter for roughly $44 billion, in a victory by the world’s richest man to take over the influential social network frequented by world leaders, celebrities and cultural trendsetters.
Twitter agreed to sell itself to Mr. Musk for $54.20 a share, a 38 percent premium over the company’s share price this month before he revealed he was the firm’s single largest shareholder. It would be the largest deal to take a company private — something Mr. Musk has said he will do with Twitter — in at least two decades, according to data compiled by Dealogic.
