Explanation of Responses:

1. Pursuant to the Agreement and Plan of Merger dated as of July 15, 2026, by and among AtaiBeckley Inc. (the "Company"), Eli Lilly and Company, an Indiana corporation ("Parent"), and Albali Acquisition Corporation, a Delaware corporation and indirect wholly owned subsidiary of Parent ("Merger Sub"), on September 11, 2026, Merger Sub merged with and into the Company (the "Merger"), with the Company surviving as a wholly owned subsidiary of Parent.

2. At the effective time of the Merger (the "Effective Time"), each outstanding stock option of the Company, subject to certain exceptions, was automatically cancelled and converted into the right to receive (A) an amount in cash (without interest and less applicable tax withholdings) equal to the product of (1) the total number of shares of the Company's common stock subject to such stock option immediately prior to the Effective Time multiplied by (2) the excess of $6.75 over the applicable exercise price per share under such stock option and (B) one contingent value right per share (each, a "CVR" and collectively, the "CVRs"), representing the right to receive up to an aggregate of $2.50 in cash per CVR upon achievement, if any, of specified clinical and regulatory milestones, less any applicable tax withholding, for each share subject to such stock option immediately prior to the Effective Time (without regard to vesting).
