Mirion delivered a strong Q1 2025, with adjusted free cash flow of $29M (62% conversion of adjusted EBITDA), 11.5% order growth (driven by nuclear power), and organic revenue growth of 6%; adjusted EBITDA was $47M (18.2% YoY increase) with margins up 260 bps to 23.1%.
The company reaffirmed its full-year 2025 guidance for organic revenue growth, adjusted EBITDA ($215M–$230M), adjusted EPS ($0.45–$0.50), and adjusted free cash flow, while raising total revenue guidance due to FX tailwinds and slightly lowering the low end of EBITDA margin guidance to account for non-tariff impacts.
Mirion acquired OncoSpace, a small cloud-native data analytics platform for radiation oncology, expected to enhance its cancer care portfolio; the deal is strategically significant but immaterial to near-term financials.
Tariff exposure in China is estimated at a $7–$9M headwind for 2025 (mainly from US-made medical products sold into China), but mitigating actions and possible product exemptions could reduce this; net 2025 adjusted EBITDA impact from tariffs and FX is projected between a $3M tailwind and an $8M headwind.
Nuclear power remains a key growth driver, with 79% of Q1 nuclear order growth from the existing fleet; management expects high single-digit growth in the nuclear power end market for the full year and sees a robust pipeline of $300M–$400M in large one-time opportunities, mostly expected to be awarded in 2025.
