While [[Arm (company)|Arm]] is a fabless semiconductor company (it does not manufacture or sell its own chips), it licenses the [[ARM architecture family]] design to a variety of companies.
Those companies in turn sell billions of ARM-based chips per year—12 billion ARM-based chips shipped in 2014,<ref>
