Overview
ASML is the critical lithography supplier to leading chipmakers, with the sole commercial EUV position supported by extreme technical complexity, exclusive optics supply, and decades of cumulative R&D. H1 2026 sales were EUR18.1B; using ASML's rounded quarterly technology mix, EUV represented about 44% of total sales, DUV 26%, applications 2%, and Installed Base Management 29%. EUV carries the strongest, directly evidenced moat, and Intel's current High-NA qualification supports ASML's roadmap credibility. DUV remains an oligopoly with moderate process-matching and requalification friction tied to nanometer-level fleet overlay, though it is more substitutable than EUV. Applications is smaller and contested, while the installed base supports recurring OEM service and upgrade demand. Principal risks are export controls, supplier concentration, rival technical progress, and semiconductor-capex cyclicality.

EUV lithography systems (incl. High-NA)
Extreme ultraviolet (EUV) lithography systems
Revenue share is estimated from H1 2026 net system sales and the rounded quarterly technology mix: EUV was 66% of Q1 system sales and 57% of Q2 system sales. Supplier list reflects ZEISS optics and TRUMPF laser involvement in the EUV ecosystem.
Supply Chain Control
Supply
Supply Chain Control
Strength
Durability
Confidence
Evidence
EUV capability depends on tightly coupled, hard-to-replicate subsystems (especially optics). ZEISS SMT is described as an exclusive optics supplier for ASML EUV tools.
Supply Chain Control moat: definition, examples, and stocks
Erosion risks
- Supplier concentration (ZEISS optics)
- Geopolitical export controls disrupt supply chain
Leading indicators
- ZEISS SMT capacity expansions
- EUV/High-NA shipment cadence
- Critical component lead times
Counterarguments
- A new optics supplier could emerge with state backing
- Customers may delay node transitions, reducing EUV volumes
Capex Knowhow Scale
Supply
Capex Knowhow Scale
Strength
Durability
Confidence
Evidence
High-NA EUV tools are extremely expensive and technically complex, implying large capital and R&D barriers to entry.
Capex Knowhow Scale moat: definition, examples, and stocks
Erosion risks
- State-backed competitor programs (e.g., China EUV)
- Technology substitution (multi-patterning, advanced packaging)
Leading indicators
- Competitor EUV prototype milestones
- Customer EUV layer counts per node
- ASML EUV backlog / book-to-bill
Counterarguments
- If a government subsidizes a rival regardless of economics, entry barriers may fall
- Alternative scaling paths could reduce EUV intensity at the leading edge
Brand Trust
Demand
Brand Trust
Strength
Durability
Confidence
Evidence
Leading chipmakers rely on ASML as the critical supplier of EUV tools; procurement tends to favor proven uptime, yield and roadmap credibility.
Brand Trust moat: definition, examples, and stocks
Erosion risks
- Customer dual-sourcing efforts (where possible)
- Reputation damage from shipment delays or reliability issues
Leading indicators
- Customer capex allocation to EUV vs alternatives
- Field reliability metrics (uptime, wafers per hour)
- High-NA adoption timelines
Counterarguments
- If ASML misses roadmaps, customers could shift to more multi-patterning or older tools
- Large customers could internalize more process know-how, reducing vendor leverage
DUV lithography systems
Deep ultraviolet (DUV) lithography systems
Revenue share is estimated from H1 2026 net system sales and the rounded quarterly technology mix: DUV was 32% of Q1 system sales and 40% of Q2 system sales. DUV is more contested than EUV, so confidence remains lower.
Switching Costs General
Demand
Switching Costs General
Strength
Durability
Confidence
Evidence
DUV scanners operate in tightly matched fleets where nanometer-level overlay and DUV to EUV cross-matching affect yield. Replacing a scanner family can require process matching, calibration and requalification, although Nikon and Canon remain viable in less demanding layers.
Switching Costs General moat: definition, examples, and stocks
Erosion risks
- Nikon or Canon improve overlay, throughput and service economics
- Mature-node customers prioritize acquisition price over fleet matching
- Standardized process-control software reduces requalification friction
Leading indicators
- DUV share of bookings and system sales
- Matched-machine overlay performance versus competitors
- Customer adoption of mixed-vendor scanner fleets
Counterarguments
- Technical matching does not prove high commercial churn or pricing power
- DUV is more substitutable than EUV and customers can qualify alternatives over time
Applications, metrology and inspection
Semiconductor metrology, inspection and process-control systems linked to lithography workflows
Revenue share is estimated from H1 2026 net system sales and the rounded quarterly technology mix: Metrology & Inspection was 2% of Q1 system sales and 3% of Q2 system sales.
Ecosystem Complements
Network
Ecosystem Complements
Strength
Durability
Confidence
Evidence
ASML applications products complement lithography workflows through YieldStar optical metrology and e-beam inspection, but compete against established process-control vendors.
Ecosystem Complements moat: definition, examples, and stocks
Erosion risks
- Process-control leaders out-innovate in standalone metrology/inspection
- Customers standardize on non-ASML inspection workflows
- Lower leading-edge capex reduces attach opportunities
Leading indicators
- Metrology and inspection system sales
- YieldStar and e-beam adoption
- Applications attach rate to EUV/DUV systems
Counterarguments
- ASML is not the broad process-control leader
- Customers can mix ASML lithography with third-party inspection tools
Installed Base Management (service, upgrades, field options)
Service, upgrades and field options for installed ASML lithography tools
Revenue share uses H1 2026 Installed Base Management sales of EUR5.250B divided by H1 total net sales of EUR18.093B.
Service Field Network
Supply
Service Field Network
Strength
Durability
Confidence
Evidence
Global field service and upgrade capability monetizes performance improvements and supports high tool utilization at customer fabs.
Service Field Network moat: definition, examples, and stocks
Erosion risks
- Third-party service providers for mature tools
- Customers internalize more maintenance capability
Leading indicators
- Installed Base Management sales growth
- Upgrade attach rate
- Spare-part lead times
Counterarguments
- Independent service organizations can undercut on older tools
- As tools improve reliability, service intensity may fall
Installed Base Consumables
Demand
Installed Base Consumables
Strength
Durability
Confidence
Evidence
Large installed base drives ongoing demand for OEM parts, field options and productivity upgrades.
Installed Base Consumables moat: definition, examples, and stocks
Erosion risks
- Parts grey market / refurb ecosystem
- Regulatory restrictions limiting service to certain regions
Leading indicators
- Service contract coverage
- Field option revenue mix
- Installed base growth vs retirements
Counterarguments
- Customers may source some parts/services from third parties
- Export restrictions can reduce addressable installed base in some geographies
