Explanation of Responses:

( 1 )On June 5, 2024, GS Sponsor II LLC (the "Sponsor") surrendered to Mirion Technologies, Inc. (the "Issuer") warrants to purchase 8,500,000 shares of the Issuer's Class A Common Stock ("Class A Common Stock") in exchange for 1,768,000 shares of Class A Common Stock. As a result of this exchange, the Reporting Persons ceased to be subject to Section 16 of the Securities Exchange Act of 1934. ( 2 )These securities are or were held by Sponsor. Each of The Goldman Sachs Group, Inc. ("GS Group") and its subsidiary, Goldman, Sachs & Co. LLC ("Goldman Sachs"), may be deemed a beneficial owner of Issuer securities held by Sponsor, but each disclaims beneficial ownership thereof except to the extent of its pecuniary interest, if any. ( 3 )These securities are held by GS Acquisition Holdings II Employee Participation LLC and GS Acquisition Holdings II Employee Participation 2 LLC (the "Employee Participation Vehicles"). Each of GS Group and Goldman Sachs may be deemed a beneficial owner of Issuer securities held by the Employee Participation Vehicles, but each disclaims beneficial ownership thereof except to the extent of its pecuniary interest, if any. ( 4 )In connection with the completion of the Issuer's initial public offering, Sponsor purchased an aggregate of 8,500,000 private placement warrants, each exercisable to purchase (subject, initially, to the satisfaction of certain material conditions) one share of the Issuer's Class A Common Stock for $11.50 per share. Certain material conditions to the exercisability of these warrants were satisfied upon the occurrence of the Issuer's initial business combination and these warrants were exercisable (including by cash settlement) 30 days following such date.
