ASML is the irreplaceable EUV gatekeeper of the AI era—compounding with monopoly economics, but exposed to a geopolitical choke point.
Overview
ASML is the indispensable supplier to the global semiconductor industry as the sole provider of EUV lithography, the critical technology needed to manufacture the most advanced chips powering AI and high-performance computing. It monetizes both high-priced system shipments (EUV and DUV scanners) and a large, growing installed-base management stream that delivers recurring service, upgrades, and software across 5,300+ systems in the field. Customers are highly concentrated among elite fabs—TSMC, Intel, and Samsung—along with major memory manufacturers. Demand is increasingly driven by the AI infrastructure buildout (advanced logic plus HBM), while mature-node applications (automotive/IoT/5G) sustain DUV volumes. ASML’s advantage is reinforced by a 100% EUV share, deep IP, and an ecosystem moat, but its outlook is meaningfully shaped by export controls and China exposure.
