Item 1 Comment:
This Amendment No. 5 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 GBP 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.
CUSIP number 20451W101 has been assigned to the American Depositary Shares ("ADSs") of the Issuer, which are quoted on The Nasdaq Stock Market under the symbol "CMPS." Each ADS represents one Ordinary Share of the Issuer. No CUSIP number has been assigned to the Ordinary Shares of the Issuer.
In connection with a corporate reorganization, ATAI Life Sciences AG was converted into a German GmbH in April 2025. As a result, the Ordinary Shares of the Issuer reported herein are held directly by ATAI Life Sciences N.V | ||
