Re: Retention Bonus

We consider your continued service and dedication to Mirion Technologies (US), Inc. (fka Mirion Technologies, Inc. and thereafter “Mirion”) essential to our long range plan. To incentivize you to remain employed with Mirion, subject to approval by Mirion’s compensation committee, we are pleased to offer you a retention bonus, as described in this letter agreement (the “Agreement”).

1.Retention Bonus Amount and Payment

To incentivize your continued employment with Mirion through the fourth anniversary of the Effective Date (as defined below) (the “Retention Period”), and subject to the terms and conditions set forth in this Agreement, Mirion agrees to pay you a retention bonus in the amount of One Million Dollars (USD $1,000,000), less all applicable withholdings and deductions required by law (the “Retention Bonus”). The Retention Bonus shall be paid to you on or about October 7, 2022.

2.Clawback of Retention Bonus

If, during the Retention Period, (x) your employment with Mirion is terminated either (A) by Mirion for Cause, or (B) by you other than for Good Reason (as such terms are defined in your Third Amended and Restated Employment Agreement dated as of May 1, 2020, as first amended on December 27, 2021 (as it may be further amended, restated or otherwise modified, the “Executive Employment Agreement”)), or (y) you give notice of your intent to terminate your employment with Mirion other than for Good Reason prior to the end of the Retention Period (such termination date in (A) or notice of termination in (B), the “Termination Date”), you agree to repay the following portion of your Retention Bonus to Mirion within thirty (30) days after such termination of your employment: (1) if the Termination Date occurs prior to the first anniversary of the Effective Date, 100% of the Retention Bonus; (2) if the Termination Date occurs on or after the first anniversary of the Effective Date but prior to the second anniversary of the Effective Date, 75% of the Retention Bonus; (3) if the Termination Date occurs on or after the second anniversary of the Effective Date but prior to the third anniversary of the Effective Date, 50% of the Retention Bonus; and (4) if the Termination Date occurs on or after the third anniversary of the Effective Date but prior to the fourth anniversary of the Effective Date, 25% of the Retention Bonus. Notwithstanding the foregoing, you will not be required to repay the Retention Bonus to Mirion if: (i) you remain continuously employed with Mirion through the end of the Retention Period, or (ii) your employment during the Retention Period is terminated (A) by Mirion for any reason other than Cause, (B) by you for Good Reason, (C) by you within

3.Miscellaneous

This Agreement shall not be construed as creating any contract for continued employment between you and Mirion (or any successor), and nothing herein contained shall give you the right to be retained as an employee of Mirion. Accordingly, your employment remains at-will, meaning that you and Mirion may terminate the employment relationship at any time, with or without cause, and with or without notice as set forth in your Executive Employment Agreement.

This Agreement will become effective on the date of last signature (the “Effective Date”), and it may not be amended or modified unless in writing signed by both the Chief Executive Officer of Mirion and you. Approval of this Agreement and any modification or amendment to this letter agreement is subject to the approval of the board of directors of Mirion Technologies, Inc. (or its compensation committee).
