ARM Holdings plc is one of the most important technology companies in the world — even though most people have never heard of it.
ARM does not make chips.
Instead, it designs the CPU architecture that other companies use to build their chips. ARM licenses this technology to companies like Apple, NVIDIA, Qualcomm, Amazon, Samsung, and many others.
Nearly every smartphone, many laptops, and a growing number of data-center and AI systems run on ARM.
How ARM Makes Money (Why This Matters)
ARM operates a royalty and licensing model:
- Upfront license fees when customers adopt ARM designs
- Ongoing royalties every time a chip using ARM ships
ARM:
- Does not own factories
- Does not hold inventory
- Does not compete with its customers
This makes ARM a capital-light, high-margin business that can scale globally with relatively low physical risk.
Where ARM Is Used Today
ARM began in mobile, but today it spans the entire computing stack:
- Mobile: ~99% of smartphones
- PCs & laptops: Apple Silicon, Windows on ARM
- Data centers: AWS Graviton, NVIDIA Grace
- AI systems: CPUs that feed GPUs and accelerators
- Automotive & IoT: Cars, sensors, embedded devices
As power efficiency becomes more important, ARM’s relevance continues to grow.
ARM’s Moat (Why It’s Hard to Replace)
ARM’s strength is not just its technology — it’s the ecosystem:
- Decades of software built for ARM
- Compilers, operating systems, and tools already optimized
- High switching costs for customers
Once a company builds its platform around ARM, leaving is difficult and expensive. This creates a wide and durable moat.
The SoftBank Connection (Important Context)
ARM is about 90% owned by SoftBank Group.
This matters because:
- ARM is SoftBank’s crown jewel
- Buying SoftBank means buying ARM plus leverage, venture bets, and manager risk
- Buying ARM directly gives investors clean exposure to the core business
ARM is the stable engine inside SoftBank’s far more volatile structure.
Key Metrics to Know (High Level)
ARM is best judged as an IP licensing business, not a manufacturer.
Some important characteristics:
- Very high gross margins (reflecting IP economics)
- Low capital intensity (no fabs, no inventory)
- Royalty-based recurring revenue
- Low reported ROIC today, due to:
- Heavy R&D investment
- Accounting treatment of IP
- Ongoing expansion into data centers and AI
Low ROIC today does not mean a weak business — it reflects front-loaded investment in a long-term moat.
Valuation: High Quality, High Expectations
ARM currently trades at a premium valuation.
The market is pricing in:
- Continued growth in AI, cloud, and custom silicon
- ARM’s expanding role beyond mobile
- Long-term operating leverage
This leaves little room for disappointment.
My Fair Value View
Based on ARM’s business quality, growth potential, and risks:
- High end of fair value: $117
- Low end of fair value: $95
How I interpret this:
- Below ~$95 → attractive
- $95–$117 → fairly valued, scale carefully
- Above ~$117 → priced for optimism
ARM is a great business, but not one to chase at any price.
Bottom Line
ARM Holdings is the quiet infrastructure layer behind modern computing — a capital-light, wide-moat licensing business that benefits as the entire tech industry grows. While SoftBank owns about 90% of ARM and uses it as the backbone of its portfolio, ARM itself offers a cleaner, lower-risk way to access this long-term thesis. The key risk today is valuation, not business quality.
