The five investor questions

80

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $612M to $925M, increasing; diluted EPS -0.86 to 0.11, increasing.

71

Median gross margin 43.2% over 7y, very stable.

0

Median ROIC 0.1%, above the 12% hurdle in 0% of years.

53

Net debt/EBITDA 0.2x, interest coverage 1x.

44

Owner earnings changed trend unclear over up to the ten most recent annual observations.

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 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.

Model details under moat-index@3.0.0: zero-growth multiple 11.1×, capped-growth comparison at no more than 18×; 9% discount rate; high-end growth 0% (capped at 4%) using min(5y revenue CAGR, 5y diluted-EPS CAGR), clamped to 0%–4%; maintenance capex uses min(capex, D&A); abstain when D&A is unavailable. This is a disclosed model range, not intrinsic value as fact.

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.

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.

This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.

Records still being gathered — partial as of retrieval Aug 31, 2026.

Trailing-12-month totals and the 90-day cluster result are withheld because this issuer walk is incomplete.

No reported Form 4 rows were captured for MIR; the incomplete walk cannot establish zero activity, zero counts, or a negative cluster result.

Track record

How Mirion Technologies, Inc.’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.

Point-in-time scores 2020–2025, one methodology version · reconstructed from filings on file each Dec 31 — never with hindsight

Point-in-time Moat Score (dot colored by tier)Indexed price (total-return (dividends reinvested))Rated Wide-moat that year

How to read this: each dot is what the engine would have scored MIR on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score100200Indexed price · log scale (2021 = 100)2020202120222023202420252026

Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.

What followed, in the years it rated Wide

In the reconstructed history shown, MIR did not rate Wide-moat in any year, so there is no wide-moat track record to report. That absence is itself the honest answer — we don’t manufacture a comparison where the rating never earned one.
