Mirion’s Nuclear Focus Drives Strong Q3 Results and $65 Million in Major Orders
Solid Revenue Growth and a Swing to Profit
Mirion Technologies (NYSE: MIR) posted a 7.9% revenue increase to $223.1 million in Q3 2025, marking continued operational momentum in the nuclear power market. After a $14 million net loss in the same period last year, the company reported $3.1 million in GAAP net income, reflecting significant improvement. Adjusted EBITDA also saw a notable boost, rising 14.7% to $52.4 million compared to Q3 2024, and adjusted earnings per share reached $0.12 versus $0.08 last year.
| Financial Metric | Q3 2025 | Q3 2024 | % Change |
|---|---|---|---|
| Revenue (millions) | $223.1 | $206.8 | +7.9% |
| GAAP Net Income (millions) | $3.1 | ($14.0) | N/A |
| Adjusted EBITDA (millions) | $52.4 | $45.7 | +14.7% |
| Adjusted EPS | $0.12 | $0.08 | +50.0% |
Major Nuclear Sector Wins Fuel Growth and Visibility
Mirion’s Q3 strength was amplified by key wins in the nuclear market, underscoring its shift toward higher-quality revenue streams. During the quarter, the company secured an approximately $10 million order for a new small modular reactor build. In October, it added another $55 million contract for its Asia installed base. These two awards contribute to Mirion’s previously announced $350 million large opportunity pipeline, of which $285 million remains to be awarded (with $175 million anticipated in 2025 and $110 million pushed to 2026 due to timing).
| Nuclear Sector Pipeline Highlights | Amount (millions) |
|---|---|
| Q3 Small Modular Reactor Order | $10 |
| October 2025 Asia Installed Base Order | $55 |
| Large Opportunity Pipeline Remaining | $285 |
The nuclear segment now comprises an estimated 45% of Mirion’s total revenue, driven by the closing of the Certrec acquisition in July and the recently announced (pending) acquisition of Paragon Energy Solutions. These deals expand Mirion’s portfolio and market presence in U.S. nuclear power with additional products, software, and services.
Guidance Raised for Free Cash Flow, Confidence in 2025 Outlook
Management reaffirmed its guidance for revenue, organic revenue, adjusted EBITDA, and adjusted EPS, while increasing the lower end of adjusted free cash flow expectations to $100–$115 million (previously $95–$115 million). Key 2025 targets now include:
- Revenue growth: 7.0%–9.0% (includes ~180 bps FX tailwind, ~100 bps from acquisitions)
- Organic revenue growth: 4.5%–6.0%
- Adjusted EBITDA: $223–$233 million (margin 24.0%–25.0%)
- Adjusted EPS: $0.48–$0.52
- Adjusted Free Cash Flow: $100–$115 million
Balance Sheet Transformation and Liquidity Surge
Mirion ended Q3 2025 with a cash balance of $933.2 million, a major jump from $175.2 million at the end of 2024, supported by convertible debt and equity issuance. Total assets climbed to $3.50 billion, and total equity reached $1.89 billion, giving the company the flexibility to pursue additional acquisitions and invest for future growth.
| Balance Sheet Item | Sept 30, 2025 | Dec 31, 2024 |
|---|---|---|
| Cash and Cash Equivalents | $933.2M | $175.2M |
| Total Assets | $3,495.8M | $2,636.0M |
| Total Stockholders’ Equity | $1,892.0M | $1,559.1M |
Takeaway: Focus on Execution as Growth Accelerates
Mirion’s latest results signal a return to profitable growth and growing dominance in the nuclear power end market. With robust order wins, rising margins, and enhanced guidance on free cash flow, the company appears well positioned to deliver on its 2025 goals and capitalize on market tailwinds in nuclear energy. Investors should watch for progress on integration of recent acquisitions and updates on the large order pipeline as the year unfolds.
