Explanation of Responses:

( 1 )On October 3, 2022, in connection with the distribution by Biohaven Pharmaceutical Holding Company Ltd. ("RemainCo") of the outstanding common shares of the Issuer ("Common Shares") pursuant to the Separation and Distribution Agreement, dated May 9, 2022, between RemainCo and the Issuer, the Issuer issued to RemainCo 35,839,857 Common Shares (the "Issuance"). ( 2 )On October 3, 2022, immediately following the Issuance, all of the outstanding common shares of the Issuer held by RemainCo were distributed by way of a pro rata distribution to RemainCo's shareholders (the "Distribution"). As a result of the Distribution, RemainCo no longer beneficially owns any common shares of the Issuer and consequently is no longer subject to the requirements of Section 16 of the Exchange Act with respect to the Issuer.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
