The shift towards Arm-based processors in datacenters is accelerating, with projections indicating that these custom-designed chips could soon account for a significant portion of global datacenter computing capacity. Industry analysts believe that within the next few years, Arm will capture a quarter of the worldwide datacenter CPU market. This transformation is particularly notable as cloud giants, who represent about half of all CPU installations globally, are increasingly adopting Arm technology. However, despite this promising outlook, there remains a lack of transparency regarding Arm's financial performance in this sector.
Arm Ltd, still majority-owned by SoftBank, has been a pioneer in processor architecture design. The company licenses its technology to various manufacturers, including those producing CPUs, FPGAs, DPUs, switch ASICs, and accelerators. These companies pay royalties on the chips they produce, enabling them to leverage Arm’s established ecosystem without starting from scratch. Yet, outside of Arm, little is known about the exact financial contributions from these partnerships, especially in the datacenter space.
The rise of Arm in datacenters has been fueled by several factors. Major cloud providers like Amazon Web Services (AWS) have been rapidly adopting Arm-based server CPUs. For instance, AWS has reported that over half of its new CPU capacity additions over the past two years were Graviton processors. Similarly, Nvidia’s Grace Arm server CPU is being integrated into projects like OpenAI’s Stargate initiative, further expanding Arm’s footprint. This growing adoption suggests that hyperscalers and cloud builders are increasingly recognizing the cost and performance benefits of Arm-based solutions.
Financially, Arm has seen robust growth. In the December quarter, royalty revenue surged 23.4% year-over-year to $580 million, while licensing revenue increased by 13.8% to $403 million. Total revenues rose 19.3% to $983 million. Research and development costs, which constitute a significant portion of Arm’s expenses, amounted to $350 million, representing 35.6% of overall revenues. Despite this investment, operating income climbed 22.4% to $442 million, with net income reaching $417 million, up 28.7% from the previous year.
Looking ahead, the integration of Arm’s Compute Sub System (CSS) is expected to contribute significantly to royalty revenue, potentially reaching double-digit percentages by fiscal 2026. Infrastructure-related royalties, particularly from networking and cloud segments, are becoming more prominent, accounting for nearly 10% of total royalty revenue. As Arm continues to gain traction among hyperscalers and cloud builders, it is crucial to monitor how this transition impacts the broader datacenter market.
The future of Arm in the datacenter hinges on maintaining competitive pricing and performance advantages. While the company’s licensing and royalty fees are increasing, excessive hikes could prompt a shift towards alternatives like RISC-V. Nonetheless, the ongoing migration to Arm-based servers is reshaping the industry, offering both opportunities and challenges for stakeholders. The coming years will reveal whether Arm can capitalize on this momentum to achieve substantial financial gains in the datacenter sector.
