ARM HOLDINGS PLC /UK (ARM)

Arm Holdings plc is a global semiconductor company whose principal activities are the licensing, marketing, research and development of central processing unit (CPU) IP, graphics processing unit IP, systems IP, compute subsystems (CSS), and associated software, tools and related services. In March 2026 it announced an expansion of its compute platform into production silicon with the Arm AGI CPU, with production expected by the end of calendar year 2026. Arm began in 1990 as a joint venture between Acorn Computers, Apple Computer and VLSI Technology, was publicly listed from 1998 to 2016, and was then taken private by SoftBank Group. Arm Holdings plc became the parent holding company in a September 2023 reorganization, and its ADSs began trading on Nasdaq under "ARM" on September 14, 2023. As of March 31, 2026, more than 350 billion Arm-based chips had reportedly shipped cumulatively.

The product portfolio is built on Arm CPUs and a common scalable architecture. Complementary offerings include GPU and NPU accelerators, system IP such as interconnects, and compute platform products (CSS), which are pre-integrated and pre-verified combinations of CPU, GPU and system IP for specific end markets. Arm also provides development tools and software, including Kleidi libraries for AI optimization. The business is organized into three AI domains: Edge AI (smartphones, IoT, industrial and embedded, consumer electronics), Physical AI (automotive and robotics), and Cloud AI (cloud compute, networking equipment and other infrastructure).

Customers include semiconductor companies, OEMs, cloud service providers and other organizations that design chips. They pay a license fee for access to Arm designs, then a per-unit royalty on substantially every chip shipped, typically a percentage of the chip's average selling price or a fixed fee per unit. Licensing models include CSS, Arm Total Access, Arm Flexible Access, TLAs and Architecture Licenses. Arm reports a market share above 99% in mobile applications processors, which accounted for about 43% of royalty revenue in the fiscal year ended March 31, 2026. Its platform supports a community of more than 22 million developers.

Arm works with an ecosystem of third-party partners, including foundries, EDA vendors, firmware and operating system vendors, game engine vendors and software developers. It competes on price, performance, energy efficiency, customization, software availability and other factors. Competitors include the x86 architecture and the open-source RISC-V architecture, and some customers are developing their own architectures. With the Arm AGI CPU, Arm may compete directly with some of its licensees. The registered office is at 110 Fulbourn Road, Cambridge, U.K., and the U.S. subsidiary, Arm Inc., has its principal office in San Jose, California.
