About ARM HOLDINGS PLC /UK (ARM)

Arm Holdings is the IP owner and developer of the Arm architecture, which is used in 99% of the world's smartphone CPU cores. Arm also has a high market share in other battery-powered devices, such as wearables, tablets, and sensors. Arm licenses its architecture for a fee, offering different license types depending on the flexibility the customer needs. Customers such as Apple or Qualcomm buy architectural licenses, which allow them to modify the architecture and add or remove instructions to tailor the chips to their specific needs. Other clients directly buy off-the-shelf designs from Arm. Both off-the-shelf and architectural customers pay a royalty fee per chip shipped. In 2026, Arm announced plans to launch its own CPU products on top of its existing royalty business.
