Overview
ASML is a Dutch company that makes the machines used to print circuits onto silicon chips. It's the only company in the world that produces EUV (Extreme Ultraviolet) lithography machines, which are required to make the most advanced chips powering AI, smartphones, and modern data centers.
What the company does
ASML designs and manufactures lithography machines used to print circuits onto silicon wafers. Its EUV machines are essential for producing the most advanced chips.
How it makes money
Selling lithography systems (each costing $150M–$400M+), plus high-margin service, software, and field options that recur over the machine's decades-long lifespan.
Moat / competitive advantage
The only producer of EUV lithography machines. Decades of R&D, deep supplier relationships (Zeiss), and incredibly high technical barriers to entry.
Business model breakdown
- •Systems: selling lithography machines — each EUV system costs $150M+ and a High-NA EUV system over $350M.
- •Installed Base Management: service, upgrades, software and spare parts on machines already deployed — high-margin and recurring.
- •Backlog-driven: orders booked years in advance, giving unusual revenue visibility.
- •Customer base is extremely narrow: TSMC, Samsung and Intel account for the majority of leading-edge orders.
Key financial concepts to understand
- Order backlog
- Confirmed orders not yet shipped — a forward-looking signal for revenue over the next 1-2 years.
- Gross margin
- ASML's gross margin reflects pricing power; it tends to expand as service revenue grows relative to system sales.
- R&D intensity
- ASML spends billions per year on R&D — the cost of maintaining the EUV monopoly.
Bull case
- •AI, EVs, and data centers all drive long-term chip demand
- •Pricing power thanks to monopoly position
- •Service revenue creates recurring cash flow
Bear case
- •Export restrictions could shrink addressable market
- •Semi cycle downturns hit equipment orders first
- •Technical roadmap risk for next-gen machines
Main risks
- •Geopolitical export controls (especially China)
- •Customer concentration in a few foundries (TSMC, Samsung, Intel)
- •Cyclical semiconductor capex
- •Single points of failure in the supply chain
Valuation questions to ask
- •How cyclical is the order book?
- •What does the long-term EUV upgrade cycle look like?
- •How exposed is revenue to China restrictions?
What could break the thesis
- •A credible competitor emerging in EUV lithography (currently considered very unlikely on a 5-10 year horizon).
- •Sustained export controls that materially shrink the addressable market in China.
- •A multi-year semiconductor capex downturn where foundries delay or cancel EUV orders.
What beginners should learn
What a 'monopoly moat' actually looks like in practice, and how customer concentration plus geopolitics can offset technical dominance.
Key terms beginners should know
- EUV
- Extreme Ultraviolet Lithography. The only technique able to print the most advanced chip designs.
- Foundry
- A company that manufactures chips for others, like TSMC making chips for Apple and Nvidia.
- Customer concentration
- When a large share of revenue comes from only a few customers, amplifying risk.
- Backlog
- Confirmed orders not yet delivered, a forward-looking indicator of revenue.
Questions to research next
- •How much of ASML's revenue currently comes from China, and how is that trending?
- •What is the timeline for the next-generation High-NA EUV machines, and who is buying them?
- •How does ASML's service revenue grow as more EUV systems are installed worldwide?
