Elon Musk is now Twitter's sole director after scrapping the social-media company's nine-person board of directors.

Musk's purchase of Twitter went through on Thursday evening. When first outlining his plans for his ownership of Twitter, Musk said he would need to take the company private to make his desired changes.

"On October 27, 2022, and as a result of the consummation of the Merger, Mr. Musk became the sole director of Twitter," the company wrote in an SEC filing published Monday.

"In accordance with the terms of the Merger Agreement, effective as of the effective time of the Merger, the following persons, who were directors of Twitter prior to the effective time of the Merger, are no longer directors of Twitter: Bret Taylor, Parag Agrawal, Omid Kordestani, David Rosenblatt, Martha Lane Fox, Patrick Pichette, Egon Durban, Fei-Fei Li and Mimi Alemayehou."
