This Schedule 13D amends the Schedule 13D initially filed by Elon Musk (the “Reporting Person”) with the Securities and Exchange Commission on April 5, 2022 with respect to the Common Stock, par value $0.000005 per share (the “Common Stock”), of Twitter, Inc. (the “Issuer” or “Twitter”), which was subsequently amended on April 11, 2022, April 14, 2022, April 21, 2022, April 26, 2022, April 27, 2022, May 5, 2022, May 25, 2022, June 6, 2022 and July 8, 2022 (collectively, including this amendment, the “Schedule 13D”). Capitalized terms used but not defined herein have the meanings given to such terms in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of the Schedule 13D is hereby amended by adding the following:

The information set forth in Item 4 of the Schedule 13D is incorporated herein by reference.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended by adding the following:

On August 29, 2022, the Reporting Person’s advisors sent a letter (the “August 29 Termination Letter”) to Twitter (on the Reporting Person’s behalf) formally notifying Twitter that the Reporting Person is terminating their merger agreement (the “Merger Agreement”) for additional bases separate and distinct from those bases set forth in the Reporting Person’s July 8, 2022 letter to Twitter terminating their Merger Agreement on that date (the “July 8 Termination Letter”). The foregoing description of the August 29 Termination Letter is qualified in its entirety by reference to the full text of the letter, a copy of which is attached hereto as Exhibit Q and incorporated herein by reference.

Because the facts described in the August 29 Termination Letter were known to Twitter and withheld from the Reporting Person, and because Twitter has taken the position that the Merger Agreement remains in effect, the Reporting Person sent the August 29 Termination Letter on the basis of the facts described therein. For the avoidance of doubt, these bases are in addition to, and not in lieu of, the bases for termination described in the July 8 Termination Letter. Although the Reporting Person believes the August 29 Termination Letter is not legally necessary to terminate the Merger Agreement because he has already validly terminated it pursuant to the July 8 Termination Letter, the Reporting Person delivered the August 29 Termination Letter in the event that the July 8 Termination Letter is determined to be invalid for any reason.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Item 6 of the Schedule 13D is hereby amended by adding the following:

The information set forth in Item 4 of the Schedule 13D is incorporated herein by reference.

Item 7. Materials to be Filed as Exhibits

Item 7 of the Schedule 13D is hereby amended by adding the following:

Exhibit Q: Letter from the Reporting Person to the Issuer, dated August 29, 2022.

SIGNATURES

After reasonable inquiry and to the best of each of the undersigned knowledge and belief, each of the undersigned certifies that the information set forth in this statement is true, complete and correct.

Date: August 30, 2022
