What Happened
Robert Hershberg, a director of AtaiBeckley Inc. (ATAI), recorded dispositions of derivative securities totaling 741,089 shares on September 11, 2026. These were not open-market sales but dispositions to the issuer in connection with the merger of AtaiBeckley into a subsidiary of Eli Lilly. Outstanding stock options were cancelled at the merger effective time and converted into a cash amount (based on the option strike and a $6.75 reference price) plus one contingent value right (CVR) per share (each CVR may pay up to $2.50 if certain milestones are met). The filing lists the transactions as derivative dispositions (code D); no per-share cash amounts are reported in the Form 4.

• For retail investors: this type of filing documents how insider option positions were settled in the transaction; it does not by itself indicate the insider’s personal view of the company’s future performance.
