Explanation of responses 10 footnotes
Footnote F1
On December 23, 2025 (the "Effective Date"), in connection with the execution of an Agreement and Plan of Merger dated as of the Effective Date (the "Merger Agreement") by and among the Issuer, SANOFI, a French societe anonyme ("Parent"), and Samba Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent, the Board of Directors of the Issuer approved acceleration of vesting of certain performance-based restricted stock units ("PSUs") and restricted stock units ("RSUs") previously granted to the Reporting Person, effective as of the Effective Date.

On the Effective Date, the Board of Directors of the Issuer determined that these PSUs (which represent 125% of the target number of PSUs) were earned according to achievement of the rTSR performance condition over a shortened performance period, with the Issuer's total stockholder return determined based on the amount payable for a share of the Issuer's common stock pursuant to the Merger Agreement ($15.50), and approved such acceleration of vesting of the earned PSUs.
