*Credit Agreement Refinancing*

On November 6, 2025, Mirion Technologies (US Holdings), Inc. and Mirion Technologies (US), Inc. (together with Mirion Technologies (US Holdings), Inc., the "Borrowers") allocated a $450,000,000 tranche of term loans (the "Replacement Term Loans") maturing in 2032. The Applicable Margin for the Replacement Term Loans is expected to be (i) 2.00% for Replacement Term Loans that are Term SOFR Loans and (ii) 1.00% for Replacement Term Loans that are ABR Loans, in each case with a 25 basis point reduction in rate upon achievement and maintenance of a Ba3 (stable outlook) corporate rating from Moody's and a BB- (stable outlook) corporate rating from S&P. The Replacement Term Loans are expected to be issued with no upfront fees, and to have a SOFR credit spread adjustment of 0.00% and a SOFR "floor" of 0.00%. The proceeds of the Replacement Term Loans will be used to refinance all outstanding Term Loans under the Credit Agreement, dated as of October 20, 2021 (as amended by the Agreement and Amendment No. 1 to Credit Agreement dated as of November 22, 2021, as further amended by Amendment No. 2 to Credit Agreement dated as of June 23, 2023, as further modified by the Holdings Assumption Agreement dated as of December 30, 2023, as further amended by Amendment No. 3 to Credit Agreement dated as of May 22, 2024, as further amended by Amendment No. 4 to Credit Agreement dated as of March 21, 2025, as further amended by Amendment No. 5 to Credit Agreement dated as of June 5, 2025, and as further amended, restated, supplemented or otherwise modified, refinanced or replaced from time to time, the "Credit Agreement"), by and among the Borrowers, Mirion IntermediateCo, Inc., the lending institutions from time to time party thereto, and Citibank, N.A as the Administrative Agent and the Collateral Agent (such refinancing, the "Term Loan Refinancing"). Capitalized terms used herein, but not otherwise defined herein are as defined in the Credit Agreement.

The foregoing transactions are subject to conditions and are anticipated to close in the fourth quarter of 2025. However, there can be no assurance that the Borrowers will be able to successfully complete the transactions, on the terms described above, or at all.
