ASML reported Q2 2026 revenue of EUR 9.3 billion and gross margin of 54%, both above guidance. The earnings number is noise. The signal is in the CEO statement: ASML is planning to add 30% to its 2026 low-NA EUV shipment base of approximately 65 systems for 2027, and investigating a further 30% increase for 2028. The same 30% expansion applies to DUV immersion, from an approximately 130-system 2026 base. ASML tool delivery is the rate-limiter for advanced-node capacity; this number directly sets the ceiling on N2 and N3 wafer availability through 2028.
Every foundry expanding advanced-node capacity (TSMC Arizona, Samsung Pyeongtaek, Intel 18A) is constrained by EUV tool availability ahead of substrate and cleanroom constraints. A 30% annual increase in low-NA EUV shipments for two consecutive years means the tool constraint eases meaningfully in 2027-2028, but it does not go away. The 65-system 2026 base growing to approximately 85 in 2027 and potentially 110 in 2028 tells you the shape of when advanced-node wafer capacity becomes less scarce.
Teams using "N2 capacity is uncertain" as a planning hedge should update their models. The 2027 EUV expansion makes advanced-node wafer slots materially more available in the second half of 2027 versus today. The practical implication: if your tape-out timing gives you a choice between Q4 2026 (high tool contention, early N2 capacity) and Q2-Q3 2027 (post-expansion, more slots), the queue risk profile is different. Build that difference into your schedule assumptions now, not when you are three months from tape-out.
