Return on invested capital, latest year9.1%
Gross margin93.6%Share of each sale left after production costs
Net margin25.9%
How we decide
A moat shows up in the numbers as high returns that last. We call it likely when the average return on invested capital over recent years is at least 15% and the gross margin at least 40%, and possible from 10%. The numbers can't show where a moat comes from (brand, network, patents), only that one seems to exist.
