Does SIGA Technologies have an economic moat?
Likely
SIGA Technologies earns 26.6% a year on the money invested in it and keeps 69% of every sale after production costs, the numbers of a business competitors struggle to copy.
The numbers behind it
Return on invested capital, average of recent years26.6%
Return on invested capital, latest year10.0%
Gross margin68.6%Share of each sale left after production costs
Net margin24.6%
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.
