Dual Super Trends: Nuclear Power and Cancer Care

Mirion's growth narrative is deeply intertwined with two powerful "super trends": the global resurgence of nuclear power and the revolution in cancer care.

Nuclear Power Renaissance

The nuclear power sector is experiencing an unprecedented revival, driven by the "voracious appetite" for clean, baseload electricity, particularly from AI-driven data centers. Hyperscalers like Microsoft (MSFT), Amazon (AMZN), Google (GOOGL), and Oracle (ORCL) are making significant investments, with Microsoft bringing a decommissioned Three Mile Island unit back online and Amazon targeting 5 gigawatts of additional nuclear energy by the late 2030s. The U.S. Department of Energy projects U.S. nuclear energy capacity could triple by 2050. This momentum is bolstered by favorable political support, including legislation to cut processing fees and reduce licensing times for advanced reactors.

Mirion's exposure to this trend is substantial, with approximately 37% of its 2024 revenue derived from the commercial nuclear power landscape. The company benefits from the global installed base (over 95% of operating commercial reactors worldwide), which drives roughly three-quarters of its nuclear power revenue, largely recurring. As nuclear operators become more profitable, they are increasing capital and operating budgets, leading to modernization upgrades, capacity expansion, and life extensions for existing plants. This is reflected in the 12% core nuclear order growth (excluding large one-time orders) in Q3 2024. Mirion is also actively engaged in the Small Modular Reactor (SMR) space, having booked approximately $9 million in SMR-related orders year-to-date 2025, with aggregate SMR orders reaching $17 million since 2023. The acquisition of Certrec Corporation for $81 million in July 2025 further strengthens Mirion's position in this market, adding regulatory compliance and digital integration solutions, with 55% of Certrec's revenue from nuclear power customers and significant AI potential from its 15 terabytes of unique industry data.

Cancer Care Innovation

In the Medical segment, the "revolution in radiopharmaceutical therapy," or Theranostics, is creating a significant opportunity. This involves a new generation of therapeutic and diagnostic drugs that precisely target cancer cells. Leading indicators, such as the 50% year-over-year sales growth of Novartis's (NVS) Pluvicto and 30% growth for PYLARIFY, underscore the market's dynamism. Mirion's dose calibrator shipments, a franchise product in this space, saw 18% unit growth year-to-date 2025. Mirion's unique data management platform connects drug makers, isotope producers, radiopharmacies, and clinicians, providing a critical "perch in the data flows" of this rapidly expanding market.

The company's Radiation Therapy Quality Assurance (RTQA) business also contributes, driven by growing and aging demographics and the adoption of advanced software and hardware solutions for improved patient outcomes and administrative efficiencies. The strategic alliance with Siemens Healthineers (SHL), for instance, aims to expand the global reach of Mirion's SunCHECK software platform, a workflow solution designed to drive efficiency and accuracy in radiation therapy clinics.

Financial Performance and Strategic Execution

Mirion's financial performance in Q2 2025 reflects the positive momentum from these market trends and effective operational execution. Total revenue for Q2 2025 reached $222.9 million, a 7.6% increase year-over-year, with organic revenue growing 5.4%. Adjusted EBITDA rose 4.9% to $51.2 million, demonstrating strong operating leverage. For the six months ended June 30, 2025, net income was $8.9 million, a significant improvement from a $38.5 million net loss in the prior year period. This turnaround was primarily driven by a $16.3 million unrealized foreign currency gain, increased revenues across both segments, decreased interest expense, and reduced amortization of intangible assets.

The Medical segment's revenue grew 10.9% (10.1% organic) in Q2 2025, with income from operations increasing by $5.9 million, benefiting from reduced amortization and higher volumes. The Nuclear Safety segment saw revenue growth of 5.8% (2.9% organic), with income from operations increasing by $0.5 million, primarily due to revenue changes and lower amortization expenses from fully amortized intangible assets. While the Nuclear Safety segment's Adjusted EBITDA declined slightly in Q2 2025 due to non-recurring transactional headwinds in France and project cost increases in the U.K., management expects margins to stabilize and rebound.

Mirion's focus on operational efficiency, driven by its proprietary Mirion Business System, is yielding tangible results. Procurement initiatives and footprint rationalization are contributing to margin expansion and improved working capital velocity. The company's net cash provided by operating activities increased by $26.8 million to $48.0 million for the first half of 2025, primarily due to improved net income and working capital management.

Capital Structure and Outlook

Mirion has significantly optimized its capital structure, enhancing its financial flexibility. In May 2025, the company successfully completed a $400 million convertible note offering at a low 0.25% interest rate, due 2030. The proceeds were strategically deployed to repurchase $31 million of Class A Common Stock, fund $44.6 million in capped call transactions (limiting dilution), and refinance $256 million of its term loan, extending its maturity to June 5, 2032. This move substantially reduced the company's debt service costs and improved its overall debt profile. As of June 30, 2025, Mirion was in compliance with all debt covenants.

Looking ahead, Mirion has raised its 2025 guidance, reflecting a bullish outlook for the second half of the year. Total revenue growth is now projected to be between 7% and 9%, up from 5-7% previously, incorporating a 125 basis point tailwind from foreign exchange and a 100 basis point improvement from the Certrec acquisition. Adjusted EBITDA is expected to be between $223 million and $233 million, an increase from the prior range. Adjusted free cash flow is forecasted at $95 million to $115 million, representing a significant increase in both total dollars and conversion rate, driven by higher expected EBITDA, lower cash taxes, and net interest expense savings. Adjusted EPS is expected to be between $0.48 and $0.52 per share. The company's backlog stands at $819 million as of June 30, 2025, providing visibility to approximately 49% of its expected 2025 revenue. A substantial pipeline of approximately $350 million in new order opportunities is expected to be awarded by year-end 2025, with management confident in securing a fair share.

Risks and Challenges

Despite the strong tailwinds, Mirion faces several risks. Geopolitical and trade conditions, including the Russia-Ukraine conflict and U.S.-China relations, can lead to increased inflation, supply chain disruptions, and tariffs. While Mirion has a regionalized supply chain and mitigating actions (e.g., alternative sourcing, production shifts), the situation remains dynamic. The company's exposure to Russian-related projects includes $17.6 million in net contract assets and $122.8 million in backlog. U.S. government budgetary headwinds, particularly impacting the Labs & Research business, have led to a revised expectation of modestly negative growth in that segment. The SMR market, while promising, is expected to undergo consolidation, with Mirion cautiously navigating the 127 designs currently in play. Additionally, fixed-price government contracts carry inherent risks of cost overruns, and while medical reimbursement dynamics are generally favorable for Mirion's segments, changes could pose a challenge.
