EXPLANATORY NOTE

This Amendment No. 2 (this “Amendment”) amends the initial Schedule 13D (the “Initial Filing”) filed jointly by GS Sponsor II LLC (the “Sponsor”), GSAH II PIPE Investors Employee LP (“GSAH II PIPE Investors”), and GSAM Holdings LLC (“Holdings”), on November 1, 2021, as previously amended on October 19, 2022, and relates to the Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), of Mirion Technologies, Inc., a Delaware corporation (the “Issuer”). Sponsor, GSAH II PIPE Investors and Holdings are collectively referred to herein as the “Reporting Persons.” Disclosure items set forth in the Initial Filing as previously amended shall remain in effect, except to the extent expressly amended or superseded by this Amendment (the Initial Filing as previously amended and amended hereby, the “Schedule 13D”). All capitalized terms used and not expressly defined in this Amendment have the respective meanings ascribed to such terms in the Initial Filing as previously amended.

ITEM 5.

INTEREST IN SECURITIES OF THE ISSUER

Item 5 is hereby amended and restated as follows:

(a) and (b)

The aggregate number and percentage of Class A Common Stock beneficially owned by each Reporting Person is based upon the 200,113,340 shares of Class A Common Stock outstanding as of October 28, 2022, as reflected in the Form 10-Q filed by the Issuer with the U.S. Securities and Exchange Commission (“SEC”) on November 3, 2022, together with, where such Reporting Person beneficially owns the private placement warrants, 8,500,000 shares of Class A Common Stock underlying the private placement warrants.

GSAH II PIPE Investors has the shared power to vote or direct the vote of the 2,600 shares of Class A Common Stock of which it is the record owner.

The Sponsor has the shared power to vote or direct the vote of, and the shared power to dispose or direct the disposition of (i) the 16,025,000 shares of Class A Common Stock of which it is the record owner, and (ii) the 8,500,000 shares of Class A Common Stock that it has the right to acquire, within sixty days, upon conversion of the Private Placement Warrants of which it is the record owner.

Holdings is the managing member of the Sponsor and may be deemed to have beneficial ownership over (i) the shares of Class A Common Stock of which the Sponsor is the record owner, and (ii) the shares underlying the Private Placement Warrants of which the Sponsor is the record owner. In addition, each of Employee Participation 1 LLC and Employee Participation 2 LLC are managed by a subsidiary of Holdings and, as a result, Holdings may be deemed to beneficially own (i) the 1,325,000 shares of Class A Common Stock of which Employee Participation 1 LLC is the record owner, and (ii) the 1,400,000 shares of Class A Common Stock of which Employee Participation 2 LLC is the record owner. A subsidiary of Holdings also serves as the general partner and manager of each of NRD and GSAH II PIPE Investors, so, as a

result, Holdings may be deemed to beneficially own the 2,700 shares of Class A Common Stock held of record by the PIPE Participation LLCs (as to which Holdings shares only voting power).

(c) On December 6, 2022, NRD distributed 1,300,000 shares of Class A Common Stock in kind to its limited partners and GSAH II PIPE Investors distributed 15,472,383 shares of Class A Common Stock in kind to its limited partners. A subsidiary of Holdings serves as the general partner and manager of each of NRD and GSAH II PIPE Investors.

(d) Certain employees of affiliates of Goldman Sachs & Co. LLC hold and may in the future be awarded certain contingent interests in the Class A Common Stock held by the Employee Participation Vehicles (which may be deemed beneficially owned by Holdings, as described above).

(e) On December 6, 2022, GSAH II PIPE Investors ceased to be a beneficial owner of more than 5% of the Class A Common Stock.

SIGNATURE

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
