Updated 2023 Guidance
Mirion is updating its adjusted free cash flow guidance, which was previously provided on February 14, 2023, as a result of the investment and the related repayment of indebtedness. The company now expects adjusted free cash flow of $58 million – $78 million for 2023, driven by lower interest expense.
Additionally, other updated guidance assumptions include the following:
Net interest expense of approximately $60 million (approximately $56 million of cash interest).
Approximately 197 million shares of Class A common stock outstanding, excluding Class B shares, warrants, and profits interests.
The company’s guidance contains forward-looking statements and actual results may differ materially as a result of known and unknown uncertainties and risks, including those set forth below under the heading “Forward-Looking Statements.” In addition, forward-looking non-GAAP financial measures are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in projecting and quantifying the various adjusting items necessary for such reconciliations, such as stock-based compensation expense, amortization and depreciation expense and purchase accounting adjustments, that have not yet occurred, are out of Mirion’s control, or

Use of Non-GAAP Financial Information
We believe that the presentation of non-GAAP financial information provides important supplemental information to management and investors regarding financial and business trends relating to our financial condition, and results of operations. For further information regarding these non-GAAP measures, including the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures, please refer to the financial tables below, as well as the “Reconciliation of Non-GAAP Financial Measures” section of this press release.

Basis of Presentation
As a result of the business combination (the "Business Combination") effected by GS Acquisition Holdings Corp II ("GSAH"), the company’s financial statement presentation distinguishes Mirion Technologies (TopCo), Ltd (“Mirion TopCo”) as the “Predecessor” until the closing date of the Business Combination, October 20, 2021 (the “Closing Date”). Mirion, which includes the combination of Mirion TopCo and GSAH subsequent to the Business Combination, is the “Successor” for periods starting from the Closing Date. As a result of the application of the acquisition method of accounting in the Successor period, the financial statements for the Successor period are presented on a full step-up basis as a result of the Business Combination, and are therefore not comparable to the financial statements of the Predecessor period that are not presented on the same full step-up basis due to the Business Combination. Mirion adopted a calendar year fiscal year in connection with the closing of the Business Combination.
Channels for Disclosure of Information
Mirion intends to announce material information to the public through the Mirion Investor Relations website ir.mirion.com, SEC filings, press releases, public conference calls and public webcasts. Mirion uses these channels, as well as social media, to communicate with its investors, customers, and the public about the company, its offerings, and other issues. It is possible that the information Mirion posts on social media could be deemed to be material information. As such, Mirion encourages investors, the media, and others to follow the channels listed above, including the social media channels listed on Mirion’s investor relations website, and to review the information disclosed through such channels. Any updates to the list of disclosure channels through which Mirion will announce information will be posted on the investor relations page on Mirion’s website.

Reconciliation of Non-GAAP Financial Measures
In addition to our results determined in accordance with GAAP, we believe the following non-GAAP measures are useful in evaluating our operating performance. We use the following non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison.
Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business.
Adjusted Free Cash Flow is defined as free cash flow adjusted to include the impact of cash used to fund non-operating expenses. We believe that the inclusion of supplementary adjustments to free cash flow applied in presenting adjusted free cash flow is appropriate to provide additional information to investors about our cash flows that management utilizes on an ongoing basis to assess our ability to generate cash for use in acquisitions and other investing and financing activities.
Free Cash Flow is defined as U.S. GAAP net cash provided by operating activities adjusted to include the impact of purchases of property, plant, and equipment and purchases of badges.
