Explanatory Note

This Amendment No. 3 to Schedule 13D amends and supplements the Schedule 13D originally filed with the United States Securities and Exchange Commission (the “SEC”) on May 24, 2021 (as amended, the “Schedule 13D”) relates to the ordinary shares, nominal value £0.008 per ordinary share (the “Ordinary Shares”), of COMPASS Pathways plc, a public limited company under the laws of England and Wales (the “Issuer”). Capitalized terms used herein without definition shall have the meaning set forth in the Schedule 13D.

Item 5.

Item 5(a) – (b) of the Schedule 13D is amended and restated in its entirety by inserting the following information:

As of the date of this Schedule 13D, ATAI AG beneficially owns 6,905,774 Ordinary Shares, representing approximately 10.1% of the 68,388,194 Ordinary Shares outstanding as of July 29, 2024.
