How Does ARM Make its Money?
ARM Holdings designs the instruction set architecture (ISA) and CPU core designs used in virtually every smartphone, most tablets, and an increasing share of laptops, servers, and automotive chips. The key distinction: ARM doesn’t manufacture or sell chips. Instead, it licenses its designs to chipmakers (Qualcomm, Apple, MediaTek, Samsung, etc.) who build chips based on ARM’s architecture. ARM earns money through two streams: licensing fees (upfront payments for access to designs) and royalties (per-chip fees on every ARM-based chip sold).
Over 280 billion ARM-based chips have been shipped globally, and ARM technology powers 99% of the world’s smartphones.
Revenue Breakdown
| Revenue Stream | FY2025 (Mar) | FY2024 (Mar) | YoY Growth |
|---|---|---|---|
| Royalty Revenue | $2.33B | $1.89B | +23.3% |
| License & Other | $1.33B | $0.94B | +41.5% |
| Total Revenue | $3.94B | $2.83B | +39.2% |
Royalty Revenue — 59% of Revenue
ARM earns a small royalty (typically 1-5% of the chip’s selling price) on every ARM-based chip shipped by its licensees. Royalty revenue is driven by:
- Smartphone chips: Qualcomm Snapdragon, Apple A-series/M-series, MediaTek Dimensity, Samsung Exynos — all ARM-based
- Data center CPUs: AWS Graviton, Ampere Altra, Microsoft Cobalt, Nvidia Grace — ARM is gaining share against Intel x86 in cloud servers
- Automotive chips: ADAS, infotainment, and vehicle compute platforms increasingly use ARM cores
- IoT and embedded: Billions of microcontrollers in smart devices, wearables, and industrial equipment
Royalty growth is driven by two factors: volume (more chips shipped) and value (higher royalty rates on premium chips). ARM has been successfully shifting customers to newer, higher-value architectures (Armv9 vs. Armv8), which carry higher per-chip royalties.
License & Other Revenue — 34% of Revenue
Upfront fees paid by chip designers to access ARM’s intellectual property:
- ARM Total Access: A subscription package giving licensees access to a broad portfolio of CPU, GPU, and system IP for a flat annual fee. Has grown to 30+ customers including AMD, Intel, and Samsung.
- Technology licensing: Customers licensing specific CPU cores (Cortex-A, Cortex-X, Neoverse) for new chip designs.
- Flexible Access: A program allowing exploration and prototyping before committing to full licenses.
License revenue tends to be lumpier than royalties, as it depends on when new licensing agreements are signed.
Income Statement Overview
| Metric | FY2025 | FY2024 |
|---|---|---|
| Total Revenue | $3.94B | $2.83B |
| Cost of Revenue | $0.58B | $0.52B |
| Gross Profit | $3.36B | $2.31B |
| Operating Expenses | $2.72B | $2.46B |
| Operating Income | $0.64B | -$0.15B |
| Net Income | $0.63B | -$0.04B |
Key Financial Metrics
- Gross Margin: 85.3% — Exceptionally high. ARM’s product is intellectual property (chip designs), which has near-zero marginal cost to distribute once designed.
- Operating Margin: 16.2% — ARM swung to profitability in FY2025 after its September 2023 IPO, benefiting from AI-driven demand for new chip designs and higher royalty rates.
- Revenue Growth: +39.2% — Accelerating growth driven by Armv9 adoption, data center expansion, and AI-related chip design starts.
- Royalty Revenue per Chip: Trending higher as Armv9 chips carry 2x the royalty rate of older Armv8 designs.
Where Does ARM Spend its Money?
- R&D (~$1.87B): ARM’s primary expense. Designing next-generation CPU, GPU, and NPU (neural processing unit) architectures requires deep investment in circuit design, verification, and software tooling. ARM employs ~7,500 engineers globally.
- Sales & Marketing (~$0.37B): Business development with licensees, ecosystem partnerships, developer outreach.
- G&A (~$0.48B): Corporate overhead, including costs associated with being a recently re-listed public company.
- Cost of Revenue (~$0.58B): Primarily amortization of acquired IP, software tools, and support costs for licensees.
What to Watch
- Armv9 transition — As more chips ship with Armv9 architecture (vs. older Armv8), ARM’s royalty rate per chip increases. Management has stated Armv9 royalties can be 2x higher. This transition is the most important revenue growth driver for the next 3-5 years.
- Data center penetration — ARM-based server CPUs (AWS Graviton, Microsoft Cobalt, Google Axion) are taking share from Intel x86. Every percentage point of server market share gained represents significant incremental royalty revenue.
- PC market — Apple’s M-series chips proved ARM can compete in laptops. Qualcomm’s Snapdragon X Elite and Microsoft’s push for ARM-based Windows PCs could open a massive new royalty opportunity.
- AI compute — GPU makers (Nvidia) and custom AI accelerators increasingly pair ARM CPUs as host processors. AI-driven chip design starts expand the total addressable market.
- Valuation premium — At $165B market cap on ~$4B revenue (~41x revenue), ARM is priced for sustained high growth. Any deceleration in the Armv9 transition or data center adoption could compress the valuation significantly.
