# ASML Moat

Status: published. Policy: company-analysis-1.

ASML has an evidenced technology moat: proprietary lithography capabilities, an almost ten-year development effort culminating in a customer delivery, and reported adoption of productivity improvements. Growing service revenue supports continuing customer dependence. The passages do not establish competitive exclusivity or exceptional durability. Pricing evidence is mixed: negotiated discounts and concessions are disclosed, while comparable-product realized price trends are absent. Supplier dependence, IP leakage, service substitution and export restrictions constrain resilience.

## intangible_assets

Proprietary technology and accumulated development expertise support differentiated lithography products. Reported customer adoption and completed deliveries provide operating evidence beyond a statement of technological ambition.

Durability: The almost ten-year development effort for the first full-specification EXE:5200B delivery suggests a substantial replication barrier. Continued NXE adoption supports a current advantage, but neither the development period nor IP ownership establishes a guaranteed competitive lead.

Risks: Patent expiry, imitation and previously experienced IP misappropriation could weaken differentiation. Dependence on essential optics from Carl Zeiss SMT creates a separate vulnerability. High NA's first delivery establishes progress, not broad commercial adoption.

Invalidation: The advantage would be undermined by demonstrated competing technology matching customer productivity and cost outcomes, sustained displacement of ASML systems, or repeated roadmap failures that prevent customers from obtaining the reported benefits.

## switching_costs

Continuing use of ASML systems creates demand for platform-specific service and upgrades. Service and field option revenue growth and continued product adoption support customer dependence indirectly; they do not quantify the cost of switching equipment suppliers.

Durability: An installed base that continues to generate service and upgrade demand can sustain relationships beyond initial equipment sales. The evidence supports a qualified lifecycle advantage, without proving exclusive service access or customer lock-in.

Risks: Customers can perform services themselves or use third parties, and export controls can restrict ASML's ability to serve installed systems. Revenue growth also reflects installed-base expansion and demand conditions.

Invalidation: Sustained migration of servicing and upgrades to customers or third parties, declining service attachment despite a stable installed base, or demonstrated equipment substitution with little disruption would weaken this assessment.
