Dear Fellow Stockholder:

We previously sent you proxy materials for the special meeting of stockholders of Twitter, Inc. to be held on September 13, 2022. To date, we have not received your vote. The Twitter Board of Directors unanimously recommends voting FOR all proposals at the special meeting.

Because Proposal 1, the proposal to adopt the merger agreement with affiliates of Elon Musk, requires the affirmative vote of a majority of the outstanding shares, your vote is very important, regardless of the number of shares that you own.

To ensure that your shares are represented at the meeting, please vote TODAY by telephone, via the Internet, or by signing, dating and returning the hard-copy proxy card or voting instruction form. If you received this letter by email you may also vote by simply clicking the “VOTE NOW” button in the accompanying email.

Thank you for your support,

Bret Taylor

Chairman of the Board of Directors
