        <footnote id="F1">Represents common shares of the Issuer (&quot;Common Shares&quot;) acquired by the Reporting Person in a pro rata distribution by Biohaven Pharmaceutical Holding Company Ltd. (&quot;RemainCo&quot;) to holders of its common shares (the &quot;Distribution&quot;) pursuant to the Separation and Distribution Agreement (the &quot;Separation Agreement&quot;), dated as of May 9, 2022, by and among RemainCo, the Issuer, and Pfizer Inc. (&quot;Pfizer&quot;).</footnote>
        <footnote id="F2">This amendment is being filed to correct the form of ownership reported in the Form 4 filed on October 5, 2022 (the &quot;Original Form 4&quot;). The Original Form 4 inadvertently incorrectly reported that all Common Shares acquired in the Distribution were directly held by the Reporting Person; however, as reflected in this amendment, a portion of the Common Shares acquired were indirectly held by the Reporting Person in the Vladimir Coric Family Trust, the Vladimir Coric Marital Trust, and the 401(K) Plan. There were no other changes made to the information in the Original Form 4.</footnote>
        <footnote id="F3">These Common Shares are held in a trust for the benefit of the Reporting Person's family members, excluding the Reporting Person. The Reporting Person's spouse is trustee of the trust. The Reporting Person disclaims beneficial ownership of these securities, and the inclusion of the securities held by the trust in this report and prior Section 16 filings by the Reporting Person is not an admission that the reporting person is the beneficial owner of these securities for purposes of Section 16 or for any other purpose.</footnote>
