The five investor questions

100

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $4.8B to $8.8B, increasing; diluted EPS 10.41 to 32.08, increasing.

93

Median gross margin 56.9% over 10y, very stable.

75

Median ROIC 14.1%, above the 12% hurdle in 100% of years.

40

Net debt/EBITDA 5.8x, no material interest expense disclosed.

80

Owner earnings changed +14.3%/yr over up to the ten most recent annual observations, share count n/a.

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 4% (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.

19 years of fundamentals

The business, in plain English

TransDigm Group Incorporated booked $8.8B of revenue in FY2025 in the Consumer Discretionary sector and kept 60.1% of it as gross profit — a high-margin business by that measure. After every other cost, 23.5% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $714M (FY2008) to $8.8B (FY2025) — about 15.9% a year compounded over 17 years.

It earned 19.6% on invested capital in the latest filed year, FY2025. Across the full 18-year measurable filed record, median ROIC was 13.2%. Over the v3 recent window (10 measurable filed years), median ROIC was 14.1%. The Returns on Capital filter above scores it 75/100.

The balance sheet carried $29.3B of total debt in FY2025 against $2.2B of owner earnings — roughly 13.2 years of owner earnings to retire it all. Balance-Sheet Safety scores it 40/100.

Put together: Business Trend is the strongest of the five filters (100/100) and Balance-Sheet Safety the weakest (40/100), which is how TDG lands at 78/100 — a Narrow 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.

The insider-filing service is temporarily unavailable, so no partial or guessed answer is shown for TDG.

Track record

How TransDigm Group Incorporated’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 2011–2025, 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 TDG on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score1002005001,0002,000Indexed price · log scale (2012 = 100)201120142017202020232026

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, TDG 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.
