ASML: The EUV Monopoly Powering the World’s Most Advanced Chips

As-of date: Mar 2, 2026 (Asia/Singapore). Disclaimer: For information and education only. This is not financial advice.

ASML: The EUV Monopoly Behind Advanced Chips

You may have seen a viral claim: “Every Nvidia GPU, every iPhone, every AI server depends on one company.”

That claim overshoots. Most chips do not need EUV. Many power, analog, and mature-node chips rely on older lithography tools.

But the chips that define leading-edge computing often do rely on EUV process flows. That is the real point.

ASML matters because it is the only commercial supplier of EUV lithography scanners.

Here are the key references:

EUV in 90 Seconds

ASML builds lithography machines. Lithography is how chipmakers print circuit patterns onto silicon wafers.

Smaller, cleaner patterns usually let chipmakers pack more transistors into the same area. That often improves performance and power efficiency.

DUV vs EUV

  • DUV (Deep Ultraviolet): uses longer-wavelength light. It can produce many chips, and it can even push smaller nodes with multi-patterning. Multi-patterning adds steps, time, and cost.
  • EUV (Extreme Ultraviolet): uses much shorter-wavelength light, about 13.5 nm. EUV prints smaller features more directly, which can reduce the number of steps and help enable economical leading-edge production.

EUV is not a simple upgrade. It forces a different design: vacuum operation, mirror optics, extreme cleanliness, and ultra-precise motion control.

Why ASML’s EUV Monopoly Holds

ASML did not “win” EUV with one invention. It built a working system and an ecosystem that can run at factory scale.

Three reasons competitors struggle

  • Time and learning: EUV took decades of R&D and field iteration. You cannot shortcut the learning curve.
  • Supply chain depth: EUV relies on specialized subsystems, especially optics. The precision requirements make scale manufacturing extremely hard.
  • Fab integration: Customers must integrate EUV into full production flows. Once the platform becomes the standard, it gets harder to replace.

So yes, ASML sits at a choke point. That does not mean “every chip needs ASML.” It means the most advanced chips often do.

ASML’s Latest Numbers

ASML’s Q4 2025 release shows both scale and demand visibility:

  • 2025 total net sales: €32.7B
  • 2025 net income: €9.6B
  • Backlog at end of 2025: €38.8B
  • Q4 2025 net bookings: €13.2B
  • Q4 2025 EUV bookings: €7.4B

Reuters also reported that Q4 bookings beat expectations, with AI-related demand pulling orders forward.

How to interpret the headline figures

  • Demand looks strong: customers still want tools to support leading-edge roadmaps and AI buildouts.
  • Bookings swing: big-ticket tools create lumpy quarters.
  • Backlog helps, but it is not guaranteed revenue: deliveries depend on ASML output and customer fab readiness.

Why EUV Tools Cost So Much

EUV scanners rank among the most complex production machines ever built. They cost a lot because the system must solve real physics problems.

What drives complexity

  • EUV light gets absorbed by air, so the tool runs in vacuum
  • EUV uses mirrors, not lenses, with extreme tolerances
  • The light source relies on high-energy laser interactions
  • The system must control vibration and contamination at extreme levels
  • Mechatronics and software must position wafers with nanometer precision

Those costs matter for investors because they influence revenue per tool and the long-term service stream after installation.

High-NA EUV: The Next Moat, and the Next Transition

High-NA EUV improves resolution. It supports future nodes more efficiently, and it can reduce patterning complexity if the full ecosystem matures.

Reuters reported High-NA tools cost around $400M each. Reuters also reported ASML said these tools processed over 500,000 wafers and reached about 80% uptime.

What you should watch during the High-NA ramp

  • Uptime and reliability trends in the field
  • Customer qualification timelines
  • Revenue shifts between years due to delivery timing

Geopolitics: Export Controls Shape the Business

Export policy now affects what ASML can ship and what it can service.

What is broadly understood as true

  • Reporting has said ASML has not shipped EUV tools to China since 2019 due to export licensing.
  • Dutch rules expanded licensing requirements for some advanced DUV tools.
  • Servicing restrictions matter because service is a meaningful revenue stream.

Investor takeaway: policy changes can shift demand timing and change the mix between systems and services.

China’s EUV Push: Progress, Still a Long Road

Do not fall for simple takes. China can try to replicate EUV, and it is trying. That still does not mean it will match ASML soon.

Reuters reported a state-backed effort from 2019 to 2025 to develop domestic EUV capability. Reuters said a prototype became operational in early 2025 and generated EUV light, but it was not producing chips at ASML-class manufacturing readiness. Reuters also reported a timeline closer to 2030 looked more realistic than earlier targets.

Why first light is not the finish line

  • Optics and precision manufacturing at scale remain extremely hard
  • Uptime, stability, and defect control decide commercial viability
  • Resists, masks, metrology, and process learning must mature together

Base case: ASML remains the only commercial EUV supplier for years. Still, you track progress because “slow” does not mean “impossible.”

ASML Makes Money in Two Ways

1) Systems revenue

Tool shipments drive large revenue chunks. Orders and revenue can swing by quarter because the tools are expensive and delivery schedules vary.

2) Installed base and services

Once customers install tools, they keep paying for service contracts, spare parts, software updates, and performance upgrades. This tends to be stickier than new tool demand, unless policy limits servicing.

This is why backlog and bookings matter. They signal future tool revenue and future installed base growth.

What Investors Often Miss When They Say “Monopoly”

  • Semicapex cycles: customers can pause or delay builds even in strong demand environments.
  • Customer concentration: a small number of chipmakers drive much of EUV demand.
  • High-NA execution risk: qualification takes time, and delays shift revenue across years.
  • Export-control shocks: rule changes can hit systems, services, or both.
  • Supply chain fragility: one constrained subsystem can cap shipments.
  • Long-term tech risk: alternatives could emerge over time even if EUV stays dominant today.

How to Track ASML Without Guessing the Stock Price

If you want a grounded way to follow ASML, track measurable signals:

  • Net bookings, especially EUV and High-NA mix
  • Backlog size and backlog conversion pace
  • Tool shipment volume and shipment mix
  • Gross margin trends tied to mix and execution
  • Installed base and service growth, plus any policy changes that affect servicing
  • Customer capex signals and fab timelines from leading chipmakers
  • Technology milestones such as throughput and uptime improvements

This keeps you focused on execution, not hype.

Bottom Line

ASML is not required for every chip. But ASML sits at a foundational chokepoint for the world’s most advanced chips.

ASML remains the sole commercial supplier of EUV lithography, and High-NA extends that moat. The latest results show strong demand visibility, including €32.7B in 2025 sales, €9.6B net income, €38.8B backlog, and €13.2B Q4 net bookings. Reuters also reported bookings beat expectations.

The moat is real. The risks are also real. Cycles, customer concentration, High-NA ramp timing, supply chain constraints, and export policy can all change outcomes.

If you want one sentence to keep: ASML holds a monopoly on the tool that enables leading-edge chips, and geopolitics now shapes how that monopoly earns money.
