Switching costsweight 15Fabs are designed around ASML tools; there is no second source for EUV to switch to.9
Network effectsweight 15None in the classic sense; the supplier ecosystem is captive rather than compounding.3
Scale & cost advantageweight 12Decades of R&D no rival has funded; each generation of tool costs more than the last.8
Brand & pricing powerweight 12A monopoly that names its price and has a multi-year backlog anyway.8
Cornered resourceweight 12The definitional case: EUV lithography exists at exactly one company.10
Distribution controlweight 12Sells directly to a handful of fabs who cannot go elsewhere.7
Disruption resilienceweight 12No substitute for EUV is credible within a decade; high-NA extends the lead.8
Independenceweight 10Dutch and US export controls, China exposure, and a single optics supplier in Zeiss.3
