Segment performance

SegmentRevenueYoYQoQMargin
Nuclear & Safety
Paragon contributed 15% revenue growth in Q2 and 27% year-to-date. Nuclear power end market revenue was flat organically, with growth in the installed base and SMRs offset by less new build revenue. Margins benefited from favorable product mix in Europe, good cost control, and a modest tariff refund, partially offset by dilution from the Paragon acquisition.

Risks & headwinds

Chinese New Build Order Cancellation Q3 FY26

$18M

Mitigation:Management views this as an unusual, isolated event tied to geopolitical tensions, not indicative of broader backlog quality issues. No impact on 2026 guidance or long-range plans.

Delayed Hardware Demand in Nuclear Medicine FY26

Lowered full-year guide to mid-single digits from double-digits

Mitigation:Management views this as a delay, not a decline in demand, with expectations for a pickup in H2 FY26. Strong double-digit order growth in Nuclear Medicine software business in H1.

Less Hardware Revenue in Dosimetry FY26

Full-year organic revenue expected to be negative (down from flat)

Mitigation:Impacted by tough comparables from large hardware sales in 2025. Core dosimetry services organic revenue grew mid-single digits in Q2.

Dilutive Impacts from M&A Q2 FY26

Partially offset Nuclear & Safety margins

Mitigation:Management expects to continue identifying and capturing further areas of integration and synergy to expand Paragon's adjusted EBITDA margins.

Broader Inflation Headwinds Q2 FY26

Offset by better mix and pricing

Mitigation:Favorable product mix and pricing helped to more than offset inflationary pressures.

Government Shutdown Dynamics Near-term

Potential impact on DOE orders

Mitigation:Management is watching closely for potential impacts on the pipeline of opportunities from the U.S. Department of Energy.

Why it matters

Verifying the acceleration of organic revenue growth is crucial for meeting full-year guidance and demonstrating underlying business strength.

We expect organic revenue to step up meaningfully in the back half to between 7.5% and 11.2%, driven by the nuclear power end market within Nuclear & Safety and the RTQA end market within Medical.

Q&A highlights

How much of the large opportunity pipeline is likely to convert to Mirion, and what are the primary risks?

Management believes they have a 'right to win' on all opportunities in the pipeline, which are screened for >$10M scope and >50% win probability. They won all opportunities that transacted last quarter. The biggest risk is timing, as projects can be delayed, but the opportunity set is replenishing.

“I think if we look at the opportunities that actually traded in the last quarter, I believe we won all of them. I don't think we lost anything that actually transacted over that period of time. And so we remain optimistic about our ability to continue that track record. In our view, the -- in general, the biggest risk is timing risk, where, depending on the nature of the project, the sector that it's in, et cetera, they can have a tendency to move to the right.”

Detailed narrative

Nuclear Power Momentum and Global Build-out

Mirion highlighted significant momentum in the nuclear power sector, particularly in North America. Regulatory improvements from the NRC and the Department of Energy's $17.5 billion loan program are opening financing and regulatory gateways. The DOE's Reactor Pilot Program achieved criticality across four advanced reactor designs, outperforming its target.

New power deals, such as Constellation and Walmart's agreement, and advancements in nuclear plans in New York State and Canada, further underscore the growing demand. Globally, the World Nuclear Association forecasts a tripling of nuclear capacity by 2050 to nearly 1.5 terawatts, a 45% increase from a decade ago, indicating sustained demand for Mirion's solutions.

Three Waves of Installed Base Nuclear Customer Demand

The company identifies three waves driving order growth from the installed nuclear base. The first is 'catch-up capital spending,' addressing deferred maintenance and replacement parts due to past capital rationing, fueled by plant restarts and demand for commercial-grade dedication and spare parts from the PeAks platform.

The second wave involves 'life extensions and extended power upgrades,' as operators commit to 10-20 year extensions, triggering upgrades to instrumentation and controls. The third, emerging wave is 'digital transformation,' driven by an aging workforce and the need for digital platforms to capture expertise, optimize outages, and improve thermal efficiency.

AI Strategy and Innovation

Mirion is strategically investing in AI across three pillars to gain an early adopter advantage. The first pillar focuses on accelerating product development by embedding AI into software development cycles, improving data analytics, real-time feedback loops, and testing/compliance workflows. The second pillar aims for organization-wide efficiencies, using AI for automating back-office processes and test plan development.

The third, and most exciting, pillar is developing AI-powered solutions, such as the new Plan AI dosimetry platform for faster, higher-quality patient-specific plans, and Daily QA 4 Pro, which consolidates dosimetry and imaging checks for improved efficiency in cancer treatment centers.

Backlog Quality and China Cancellation

Management emphasized continuous scrutiny of its backlog, noting that debooking events are exceedingly rare and typically tied to broader issues. The recent $18 million cancellation of a Chinese new build order, originally booked in 2019, was attributed to geopolitical tensions and stalled project progress.

Despite this, the company asserts no impact on its 2026 guidance or long-range plans, maintaining confidence in its overall backlog quality. Mirion continues to have a meaningful position in 50 out of 60 operating Chinese reactors, with a robust spare parts market averaging $8 million annually, and ongoing export opportunities for new builds and advanced reactor applications.

M&A Pipeline and Capital Allocation

Mirion maintains a strong M&A pipeline, viewing it as a critical component of its strategy, having completed approximately 20 deals over the last decade. The company expects to remain active in this area, targeting highly complementary assets. In terms of capital allocation, without further M&A, Mirion projects ending the year at approximately 2.5x leverage, indicating a net reduction in leverage.

The company's first strategic priority for capital allocation remains M&A, with a focus on smaller-sized deals.

Medical Segment Performance and Outlook

The Medical segment experienced a 1% organic revenue decline in Q2, below expectations, primarily due to nuclear medicine and dosimetry. RTQA revenue continued to grow, driven by OEM sector performance and software. Nuclear medicine saw delayed hardware demand, though its software business generated strong double-digit order growth in H1, and factory improvements have reduced lead times.

Dosimetry faced negative organic growth due to tough hardware comparables. Despite these mixed results, the company maintained its full-year Medical segment guidance, with RTQA's raised outlook offsetting the lowered expectations for nuclear medicine and dosimetry.
