Arm Holdings

Arm Holdings is a British semiconductor and software design company headquartered in Cambridge, England. The company specialises in energy-efficient processor architectures and licenses its designs to chipmakers, device manufacturers and cloud providers rather than fabricating silicon itself. Arm-based designs power the majority of the world's smartphones and have shipped in hundreds of billions of chips across consumer, industrial and infrastructure markets.

The product portfolio spans Cortex CPUs, Mali and Immortalis GPUs, Ethos neural processing units and the Neoverse platform built for data centre and cloud workloads. Arm also develops system IP, security architectures and software toolchains that help partners bring custom silicon to market faster. Its licensing and royalty model gives semiconductor firms a common architectural foundation while leaving room for differentiation at the chip level.

Beyond mobile, Arm designs reach into automotive electronics, networking equipment, edge devices, supercomputers and increasingly into accelerators for artificial intelligence workloads. The company's focus on performance per watt positions it at the centre of efforts to scale compute without proportional growth in energy consumption. As an architecture provider rather than a direct chip vendor, Arm sits upstream of much of the global semiconductor supply chain and shapes the design choices made by many of the largest names in computing.
