Technological disruption if alternative lithography methods (e.g., directed self-assembly, nanoimprint) reduce EUV dependence, though this appears unlikely before 2030 given physics constraints at sub-2nm nodes
Semiconductor industry consolidation reducing customer count - currently dependent on 3-5 leading-edge foundries (TSMC, Samsung, Intel) for majority of EUV inspection revenue
Geopolitical export restrictions on advanced semiconductor equipment to China, potentially limiting 15-20% of addressable market despite current exemptions for inspection tools
Slowing Moore's Law progression if transistor scaling economics deteriorate, reducing need for next-generation inspection capabilities
KLA Corporation or Applied Materials developing competing EUV mask blank inspection technology, though both have focused on patterned wafer inspection rather than blank mask inspection
In-house development by ASML (EUV lithography monopolist) to vertically integrate inspection capabilities, leveraging existing foundry relationships
Chinese equipment manufacturers (SMEE, Naura) attempting to develop indigenous inspection tools for domestic market, supported by government subsidies
Minimal financial risk given zero debt and $75.8B annual FCF generation
Currency exposure as Japanese manufacturer selling primarily in USD/EUR to global foundries - yen weakness benefits competitiveness but yen strength compresses translated revenues
Concentration of manufacturing in Japan creates supply chain vulnerability to natural disasters or geopolitical tensions
