ITEM 1. SECURITY AND ISSUER

This Amendment (this “Amendment No. 5”), which 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”), further amends the initial Schedule 13D (as amended prior to the date hereof, the “Initial Filing”), of GS Sponsor II LLC (the “Sponsor”), Goldman Sachs & Co. LLC (“Goldman Sachs”) and The Goldman Sachs Group, Inc. (“GS Group” and, together with Sponsor and Goldman Sachs, the “Reporting Persons”). Disclosure items set forth in the Initial Filing shall remain in effect with respect to the Reporting Persons except to the extent expressly amended or superseded by this Amendment No. 5. All capitalized terms used and not expressly defined in this Amendment have the respective meanings ascribed to such terms in the Initial Filing.

ITEM 3. SOURCE OF FUNDS

Item 3 is hereby amended by the addition of the following:

On June 4, 2024, Sponsor entered into that certain Exchange Agreement (the “Exchange Agreement”) with the Issuer, pursuant to which Sponsor agreed to surrender Private Placement Warrants to purchase 8,500,000 shares of Class A Common Stock in exchange (the “Exchange”) for 1,768,000 shares (the “Exchange Shares”) of Class A Common Stock, which were issued by the Issuer on the same date. In connection with the Issuer’s efforts to release the Exchange Shares from certain restrictive legends and permit the Exchange Shares to be held in an account maintained at Goldman Sachs, Sponsor agreed to refrain from the direct or indirect transfer of the Exchange Shares except as permitted by the terms of that certain Certificate (the “Certificate”) delivered by it to the Issuer on June 4, 2024.

ITEM 4. PURPOSE OF TRANSACTION

Item 4 is hereby amended by the addition of the following:

The disclosure made above in Item 3 of this Amendment is incorporated herein. Subject to market conditions, the price of, and liquidity for, the Class A Common Stock and other facts and circumstances and compliance with the applicable terms of the Certificate, Sponsor anticipates that it will sell, hedge or otherwise dispose of the Exchange Shares, from time to time in one or more transactions. However, Sponsor may, at any time and from time to time, review or reconsider its plans with respect to the Exchange Shares, subject to the terms of the Certificate.
