Mirion Technologies (MIR): analysis traps
Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q3 2026, to Sep 30, 2026, filed Oct 28, 2026; rules v1.1
Mirion Technologies (MIR): 1 rule of 10 triggered on the filings to Sep 30, 2026: FCF growth = the business improved. 1 to review; 1 with insufficient data; 3 not applicable. Each is a question to verify, with the normal explanation that would produce the same figures.
Check these first
FCF growth = the business improved Triggered · severity medium · confidence medium
Free cash flow rose $57M (+113%), from $50M to $107M, but working capital released $25M more cash than the year before and capital expenditure fell by $12M: 66% of the increase came from sources that need not repeat. Operating cash flow before working capital rose by $20M.
Innocent reading: An expansion programme finished, so capex fell back to maintenance levels for good.
A precise DCF value = the true value To review · confidence high
The DCF's point value is 5.35 a share (price 17.97); 41% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from 3.63 to 7.06; across every method the research ran the range is -0 to 27. The value is a range; the decimals are not information.
Innocent reading: A stable, mature business with a narrow range of outcomes, where the point value is a fair summary.
Every rule
A01 FCF growth = the business improved Triggered severity medium · confidence medium
Free cash flow rose $57M (+113%), from $50M to $107M, but working capital released $25M more cash than the year before and capital expenditure fell by $12M: 66% of the increase came from sources that need not repeat. Operating cash flow before working capital rose by $20M.
The figures and how they are read
| Fiscal year before | FY2024 |
| Fiscal year | FY2025 |
| Operating cash flow, year before | $99M |
| Operating cash flow | $143M |
| Capex, year before | $49M |

| Working capital: change in its cash contribution | $25M |
| Of which: capex cut | $12M |
| Of which: working capital released | $25M |
| Share of the increase that need not repeat | +65.5% |
| Operating cash flow before working capital: change | 19500000.00 |
FCF = operating cash flow − cash capex; ΔFCF = ΔOCF − ΔCapEx; the working-capital part is the change in the cash-bridge items (receivables, inventory, payables, accruals), with the sign of the cash flow statement
Source: FY2025 (cash flow statement, fiscal year) · FY2024 (cash flow statement, fiscal year before)
What would explain it innocently
- An expansion programme finished, so capex fell back to maintenance levels for good
- Suppliers agreed longer payment terms in a contract
- Inventory was brought down after a glut and will stay down
What to look for in the filing
- Maintenance capex (what it costs to keep the assets working)
- Supplier payment terms and any supply-chain financing
- Management's capex guidance for next year
What would show the trap does not apply
- Next year's FCF holds or rises with capex back at its earlier level and working capital no longer releasing cash
- The 10-K's capex guidance and the segment capex show the cut is a completed programme, not deferral
- The working-capital release matches a disclosed change in terms or a divestiture, not stretched payables or a collection push
Look again: next filing.

E02 Low P/E at a cyclical peak = undervalued Not applicable
a loss on a trailing or mid-cycle basis: the P/E has no meaning
E07 A precise DCF value = the true value To review confidence high
The DCF's point value is 5.35 a share (price 17.97); 41% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from 3.63 to 7.06; across every method the research ran the range is -0 to 27. The value is a range; the decimals are not information.
The figures and how they are read
| dcf value | 5.35 |
| price | 17.97 |
| terminal value share | +40.5% |
| swing by input | Operating margin / ±3 pts / 3.63 / 7.06; Revenue growth (each year) / ±5 pts / 4.58 / 6.24; WACC / ±1 pt / 4.93 / 5.87; Working capital per $ of growth / ±10 pts / 5.1 / 5.6 |
| range all methods | -0.2; 26.54 |
the DCF's point value against the share of it that is the terminal value and the value at each input moved by one step (growth ±5 pts, WACC ±1 pt, margin ±3 pts …); the range across every method the research ran
Source: 2026-11-08 (valuation research)
What would explain it innocently
- A stable, mature business with a narrow range of outcomes, where the point value is a fair summary
- The inputs that matter most are themselves well known (a regulated return, a long contract)
What to look for in the filing
- Which input you believe differs from the research's and why
- What the price implies for growth (the reverse DCF on the fair-value page)
What would show the trap does not apply
- The DCF's value is robust to the terminal growth and discount rate (the range's low end is still above the price)
- The company's cash flows over the next three years track the DCF's early years
Look again: next filing.
J06 A bank's low P/E and high profit = safe Not applicable
not a bank
J08 A REIT's low net income = the dividend is unsafe Not applicable
not a REIT
What the statuses mean
Triggered: the filings show the pattern; read the normal explanations and the missing evidence before concluding anything. To review: one quarter or a weak signal; a reader's judgement, not a pattern. Not triggered: the pattern is absent on these figures. Insufficient data: the filings read so far do not hold what the rule needs; this is not a clean bill. Not applicable: the rule is not meant for this kind of company (a bank's working capital, a loss-making quarter's EPS growth). Out of date: the latest filing is more than fifteen months old.
Severity is what the pattern could mean for cash, value or solvency; confidence is how reliable the inputs and the reading are. The two are kept apart.

Every rule and the companies it triggers on → Mirion Technologies: cash flow → Earnings quality score →
Each rule reads the company's own filings by a fixed formula and says what would explain the same figures innocently. A triggered rule is a question to verify, not a finding of manipulation, and not a view on the stock. Missing data is shown as missing, never as clear. Not investment advice.
