The nuclear power end market is anticipated to deliver double-digit organic growth in 2025, while the Medical segment is expected to return to mid-single-digit organic growth. Management foresees strong double-digit order growth in Q4 2025, particularly in the nuclear power segment. The large opportunity pipeline, currently at $285 million, is expected to see $175 million awarded by year-end 2025, with some projects potentially shifting into 2026 due to U.S. government funding dynamics.

Despite this optimistic outlook, several risks warrant consideration. Geopolitical and trade conditions, including the ongoing Russia-Ukraine conflict (with $107.3 million in backlog and $17.8 million in contract assets tied to Russian-related projects), U.S.-China relations, and the Middle East conflict, could lead to increased inflation, supply chain disruptions, and project delays. The U.S. healthcare environment continues to pressure the RTQA business due to budgetary noise and government shutdown headwinds, although management views this as a delay rather than a decline. The Labs & Research business faces muted demand from the U.S. Department of Energy and slowed order flow from China, indicating funding strain. Tariffs, particularly a $7 million-$9 million headwind from U.S.-produced medical products sold into China, pose a challenge, though Mirion's mitigating actions and potential product exemptions are expected to keep the net impact manageable. Furthermore, the successful integration of recent acquisitions like Certrec and the planned acquisition of Paragon Energy Solutions remains crucial, and the conversion of convertible debt could lead to dilution for existing shareholders.
