Is the business good?
The checks split: earnings fully cash-backed (2.9×), but margins compressing.
Operating profit is fully backed by cash. Conversion is improving vs a year ago.
Negative operating leverage, costs are rising faster than sales, squeezing margins as it grows.
Margin-driven, fat margins on slower asset turns. ROE 11% = margin × turnover × leverage.
Unless marked, from derived.
Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.

Named in ARM’s FY2026 20-F
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; ARM’s own figures are from its FY2026 20-F. Smaller customers and suppliers go unreported. A link without a share is named in one of the two companies’ annual reports, without a figure.
