Does Sterling Infrastructure have an economic moat?
Maybe
Sterling Infrastructure earns 20.3% a year on the money invested in it: decent, but not the clear sign of a wide moat.
The numbers behind it
Return on invested capital, average of recent years20.3%
Return on invested capital, latest year23.8%
Gross margin23.0%Share of each sale left after production costs
Net margin11.7%
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.
