The five investor questions
2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $612M to $925M, increasing; diluted EPS -0.86 to 0.11, increasing.
Median gross margin 43.2% over 7y, very stable.
Median ROIC 0.1%, above the 12% hurdle in 0% of years.
Net debt/EBITDA 0.2x, interest coverage 1x.
Owner earnings changed trend unclear over up to the ten most recent annual observations.
Price vs. value if growth stopped today
A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.
- $28.8M
- Unavailable — insufficient owner-earnings data
- Unavailable — insufficient growth-model data
- $16.69
- No price data
This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.
Among the current top-score group, the median current price is 238% above the zero-growth estimate across 49 of the current top 50 companies by Moat Score with both values.

9 years of fundamentals
The business, in plain English
Mirion Technologies, Inc. booked $925M of revenue in FY2025 in the Healthcare sector and kept 47.4% of it as gross profit — a solid-margin business by that measure. After every other cost, 3.1% of each revenue dollar reached the bottom line.
Across the filed record, revenue grew from $440M (FY2019) to $925M (FY2025) — about 13.2% a year compounded over 6 years.
It earned 2.5% on invested capital in the latest filed year, FY2025. Across the full 4-year measurable filed record, median ROIC was 0.1%. Over the v3 recent window (4 measurable filed years), median ROIC was 0.1%. The Returns on Capital filter above scores it 0/100.
The balance sheet carried $445M of total debt in FY2025 against $131M of owner earnings — roughly 3.4 years of owner earnings to retire it all. Balance-Sheet Safety scores it 53/100.
Put together: Business Trend is the strongest of the five filters (80/100) and Returns on Capital the weakest (0/100), which is how MIR lands at 50/100 — a Shallow moat.
This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
Exact FY and FY-1 financing invested-capital inputs are required.. Exact FY and FY-1 Operating Invested Capital inputs are required.
The explained ROIC gaps have filed inputs but no meaningful positive invested-capital denominator. Other gaps mean the item is not in the filings for that year. The series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.

Scores are logged append-only and never overwritten — this record cannot be reconstructed retroactively, which is exactly why it’s worth keeping.
Insider activity
Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”
These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.
The insider-filing service is temporarily unavailable, so no partial or guessed answer is shown for MIR.
