Mirion ("we" or the "company") (NYSE:MIR), a global provider of radiation detection, measurement, analysis, and monitoring solutions to the nuclear, medical, defense, and research end markets, today announced results for the fourth quarter and full year ended December 31, 2025.

"Mirion concluded another successful year, highlighted by record orders, strong tailwinds from key strategic end-markets, and a broadening nuclear power portfolio," commented Mirion's Chairman and Chief Executive Officer Thomas Logan. "In addition, we delivered on our Adjusted EBITDA and our Adjusted Free Cash Flow targets."

Logan continued, "We booked over $1 billion of orders in 2025, including approximately $150 million from the large opportunity pipeline previously foreshadowed. Importantly, these orders reflect growth from all three Nuclear Power verticals: new utility scale reactors, the installed base, and small modular reactors. We continue to expect meaningful order growth in 2026, including full-year contributions from Paragon Energy Solutions and Certrec."

2026 Guidance

Commenting on Mirion's full year 2026 guidance, Logan said, "2026 guidance reflects strong market fundamentals supporting growing revenue, expanding margins, and enhancing Adjusted Free Cash Flow generation."

Mirion has provided the following guidance for the fiscal year ending December 31, 2026.

• Revenue growth of approximately 22.0% – 24.0%; includes foreign exchange rate and acquisition-related tailwinds
• Organic Revenue growth of approximately 5.0% – 7.0%
• Adjusted EBITDA of approximately $285 million – $300 million; Adjusted EBITDA margin of approximately 25.0% – 26.0%
• Adjusted Free Cash Flow of approximately $155 million – $175 million; Adjusted Free Cash Flow Conversion of approximately 54% – 58% of Adjusted EBITDA
• Adjusted EPS of approximately $0.50 – $0.57 per share; now including stock-based compensation

Additional modeling and guidance assumptions are included in the earnings presentation on the Company's investor relations page.

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, merger and acquisition activity and purchase accounting adjustments, that have not yet occurred, are out of Mirion's control, or cannot be reasonably predicted. Accordingly, reconciliations of our guidance for organic revenue growth, adjusted EBITDA, adjusted EPS, adjusted free cash flow and adjusted free cash flow conversion are not available without unreasonable effort.

Use of Non-GAAP Financial Information

In addition to our results determined in accordance with GAAP, 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. Non-GAAP financial information is not a substitute for GAAP financial information and undue reliance should not be placed on such non-GAAP financial information. In addition, similarly titled items used by other companies may not be comparable due to variations in how they are calculated and how terms are defined.

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.

Organic revenues is defined as Revenues excluding the impact of foreign exchange rates as well as mergers, acquisitions and divestitures in the period.

Adjusted EBITDA is defined as net income before interest expense, income tax expense, depreciation and amortization adjusted to remove the impact of foreign currency gains and losses, amortization of acquired intangible assets, changes in the fair value of warrants, certain non-operating expenses (restructuring and costs to achieve operational synergies, merger, acquisition and divestiture expenses and IT project implementation expenses), stock-based compensation expense, debt extinguishment and income tax impacts of these adjustments.

Adjusted EBITDA margin is defined as Adjusted EBITDA divided by Revenue.

Adjusted net income is defined as GAAP net income adjusted for foreign currency gains and losses, amortization of acquired intangible assets, changes in the fair value of warrants, certain non-operating expenses (restructuring and costs to achieve operational synergies, merger, acquisition and divestiture expenses and IT project implementation expenses), stock-based compensation expense, debt extinguishment and income tax impacts of these adjustments.

Adjusted EPS is defined as adjusted net income divided by weighted average common shares outstanding — basic and diluted.

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.

Adjusted free cash flow conversion is defined as adjusted free cash flow divided by adjusted EBITDA.

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, purchases of badges and proceeds from derivative contracts.

Net leverage is defined as Net Debt (debt minus cash and cash equivalents) divided by Adjusted EBITDA plus contributions to Adjusted EBITDA if acquisitions made during the applicable period had been made before the start of the applicable period.

Operating Metrics

Order growth is defined as the amount of revenue earned in a given period and estimated to be earned in future periods from contracts entered into in a given period as compared with such amount for a prior period. Foreign exchange rates are based on the applicable rates as reported for the time period.

Adjusted order growth (decline) is defined as order growth (decline) adjusted to exclude large, one-time orders and the impact of acquisitions and divestitures.

The following tables present reconciliations of certain non-GAAP financial measures for the applicable periods.
