TDGTransDigm Group
Is the business good?
The checks split: margins widening, but thin cash backing (0.6×).
Mixed fundamental signals. Nine pass/fail tests of year-over-year health from the filings.
Operating profit outpaces operating cash flow, watch accruals and working capital.
Profits are tracking sales roughly one-for-one, limited operating leverage either way.
Against the whole market›
Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.

None disclosed.
A company has to disclose every customer behind 10% or more of its revenue. Each share comes from the latest annual report of the company that states it and shows on both companies’ pages; TDG’s own figures are from its FY2025 10-K. Smaller customers and suppliers go unreported. A link without a share is named in one of the two companies’ annual reports, without a figure.
