Business Overview

Mirion Technologies is a global leader specializing in radiation detection, measurement, analysis, and monitoring solutions. The company operates through two primary segments: Nuclear and Safety, which serves nuclear power, labs, and defense markets; and Medical, focused on radiation therapy, nuclear medicine, and diagnostic imaging. Mirion generates revenue through a combination of product sales and recurring service contracts, leveraging a category-leading position in ionizing radiation safety and analytics.

Performance Analysis

Mirion’s first quarter 2025 revenue rose 4.9% year-over-year to $202 million, with organic growth of 6% offset partially by foreign exchange headwinds. Both operating segments contributed to growth, with Nuclear and Safety revenue up 6% and Medical revenue increasing 2.7%. The company achieved a notable 11.5% increase in orders, led predominantly by nuclear power demand from the installed base, which accounted for 79% of nuclear order growth. Adjusted EBITDA grew 18% to $46.7 million, lifting margins by 260 basis points to 23.1%, driven by operating leverage and procurement savings.

Adjusted free cash flow was a standout at $29 million, representing 62% of adjusted EBITDA, reflecting improved working capital management and disciplined capital expenditures. The company repurchased 1.2 million shares for $18.6 million, aligning with its capital deployment strategy to offset dilution and maintain financial flexibility. Despite tariff headwinds, Mirion reaffirmed its 2025 organic revenue and adjusted EBITDA guidance, revising total revenue growth upward to 5% to 7%, supported by a weaker dollar and mitigating actions.

• Segment Growth Drivers: Nuclear power end market grew 17.6%, fueled by extensions and upgrades of existing plants and new builds.
• Margin Expansion Levers: Procurement process streamlining and the Mirion Business System contributed to margin gains.
• Tariff Exposure Management: Regionalized supply chain and alternative sourcing reduce net tariff impact to between a $3 million tailwind and $8 million headwind.

Overall, Mirion’s first quarter results demonstrate operational resilience, strong demand in core markets, and strategic positioning to navigate geopolitical risks while progressing toward its 2028 margin targets.

Executive Commentary

Strategic Positioning

1. Leveraging Nuclear Power Installed Base

Mirion’s growth is anchored in the installed base of nuclear power plants, which accounts for approximately 80% of nuclear revenue. The company benefits from a global shift toward extending plant lifespans and increasing capacity utilization, driven by rising demand for clean baseload energy. This structural tailwind underpins high single-digit growth expectations in nuclear power and supports sustained capital expenditures for upgrades and maintenance.

2. Mitigating Tariff and Trade Risks through Regionalized Supply Chain

Tariffs, particularly retaliatory Chinese tariffs on U.S. medical products, pose a material risk. Mirion’s local-for-local manufacturing model and diversified supply chain reduce exposure, with mitigating actions such as alternative sourcing and price adjustments expected to offset much of the tariff impact. Emerging evidence suggests potential tariff exemptions on key product classifications, which could further alleviate cost pressures.

3. Focused Capital Deployment and M&A Discipline

The company executed $18.6 million in share repurchases to mitigate dilution from equity awards, reflecting a balanced capital allocation approach. The acquisition of Oncospace, a cloud-native radiation therapy software platform, aligns with Mirion’s strategy to enhance its cancer care portfolio through software-enabled solutions. Management remains patient and disciplined in pursuing M&A amid uncertain market valuations.

4. Operational Excellence Driving Margin Expansion

Mirion’s proprietary Mirion Business System and procurement streamlining initiatives drive cost efficiencies and working capital improvements. These efforts contributed to a 310 basis point margin improvement in the Nuclear and Safety segment and a 260 basis point overall margin gain, supporting the company’s pathway to 30% adjusted EBITDA margins by 2028.

5. Navigating Macro and Geopolitical Dynamics with Vigilance

Management actively monitors geopolitical risks including U.S.-China trade tensions and government funding uncertainties. While no material impact from government procurement delays (DOGE) has been observed, caution remains. The company’s diversified end markets and compulsory nature of many products provide resilience against cyclical and political volatility.

Key Considerations

Mirion’s first quarter results reflect a confluence of strong demand, operational discipline, and strategic risk management in a complex macro environment.

• Order Momentum: Sustained nuclear power demand is a key growth driver, with a substantial $300 million to $400 million bid pipeline expected to convert mainly in the second half of 2025.
• Tariff Exposure Dynamics: China tariffs remain fluid, but mitigating actions and potential tariff exemptions reduce downside risk.
• Cash Flow Strength: High adjusted free cash flow conversion supports reinvestment and shareholder returns despite anticipated seasonal cash flow variability in Q2.
• Margin Expansion Path: Operating leverage and procurement savings are delivering tangible margin gains, but second quarter margins may be impacted by tariff mitigation timing.
• Selective M&A Approach: Acquisition activity remains disciplined amid valuation uncertainty, with focus on strategic fit and flexible deal structures.

Risks

Mirion faces risks from geopolitical tensions, particularly U.S.-China trade relations and retaliatory tariffs that could affect product costs and pricing. Government budget uncertainties and potential delays in large contract awards introduce timing risk. Foreign exchange volatility also impacts reported results, although current trends provide some offset. Execution risks include sustaining margin expansion amid cost pressures and integrating new software capabilities effectively.

Forward Outlook

For the second quarter, Mirion expects:

• Flattish margins in the Nuclear and Safety segment due to tariff mitigation timing and mix shifts.
• Year-over-year margin improvement in the Medical segment, albeit less pronounced than Q1.

For full-year 2025, management reaffirmed guidance:

• Organic revenue growth of 5.5% to 7.5%.
• Total revenue growth of 5% to 7%, improved from prior guidance.
• Adjusted EBITDA between $215 million and $230 million, with margins of 24.0% to 25.5%.
• Adjusted free cash flow of $85 million to $110 million, targeting 39% to 48% conversion of adjusted EBITDA.
• Adjusted EPS of $0.45 to $0.50 per share.

Management highlighted ongoing tariff mitigation efforts, FX tailwinds, and a resilient business model as key factors supporting the outlook.
