Shares of Twitter are sharply higher in after-hours trading in the wake of a new U.S. Securities and Exchange Commission (SEC) filing detailing changes to how Elon Musk is approaching buying the company.

In short, Musk initially indicated that he would execute a margin loan of $12.5 billion against other holdings to help finance his purchase of the social media platform. However, those have lapsed, and, per Twitter, “[c]oncurrently with the foregoing, [Elon Musk has] committed to … increase the aggregate principle amount of the equity commitment thereunder to $33.5 billion.”
