ASML

Type: Company (Semiconductor lithography equipment, Veldhoven, Netherlands) Ticker: ASML

ASML is the sole-source supplier of EUV lithography — the machines every advanced logic node (TSMC N2/A16, Samsung, Intel 18A) is patterned on. It sits one layer upstream of TSMC in the same supply chain the hardware frontier tracks: TSMC's capex line is structurally the demand signal that becomes ASML's system order book, on a multi-quarter lag. Where TSMC is the substrate beneath every AI chip, ASML is the substrate beneath TSMC. Its competitive position is a roadmap moat — no alternative EUV source exists — but the near-term question is order-book durability, not monopoly.

Q2 2026 print (primary, reported 2026-07-15)

All figures below are primary from ASML's own press release (ASML Q2'26); capacity/forward-order color is transcript-attributed.

• The beat was service/mix, not new systems. CEO Fouquet: the above-guidance quarter was "driven primarily by higher than expected Installed Base Management sales" — software-led upgrade demand. This confirms near-term revenue durability more than the forward EUV order book. Evidence: strong (primary)
• FY2026 guidance raised to €43–45B / 54–56% GM — the second raise since the February 20-F: €34–39B (20-F) → €36–40B (post-Q1) → €43–45B (post-Q2). Midpoint +€7.5B / +20.5% since the 20-F, with the GM band stepping up +3pp at both ends. Evidence: strong (primary)
• Q3'26 guide: €11.0–12.0B net sales (+23.3% QoQ), GM 55–57%. Evidence: strong (primary)

Key Contributions

• Sole EUV source — every leading-edge logic node depends on ASML litho tools; a structural roadmap moat.
• Capacity expansion — intent to add +30% to 2026's ~65-unit Low-NA EUV capacity for 2027 (further 30% under investigation for 2028); ~65 planned FY26 EUV units vs 48 shipped FY25 ≈ +35% unit growth YoY. Evidence: moderate (transcript-attributed) (ASML Q2'26)
• High-NA EUV economics are the open constraint — ~$400M/tool vs ~$200M for current EUV; TSMC has deferred high-NA adoption on cost, betting on computational lithography (cuLitho) to extend installed EUV instead. Evidence: moderate (TSMC high-NA deferral, NVIDIA cuLitho)

Risks & Constraints

• Bookings opacity — ASML stopped publishing quarterly net bookings; forward visibility is qualitative management color only (2027 orders "pretty much" complete; 2028 EUV orders "already received").
• China — ~20% of total net sales; MATCH Act overhang neither confirmed nor resolved this quarter.
• Customer concentration — four >10% customers; Taiwan (essentially TSMC) rose to 25.5% of FY2025 net sales, tying ASML's book to TSMC's capex cycle.
• High-NA adoption timing — if leading-edge customers defer high-NA (as TSMC has), the premium-tool ramp slips.

Mentioned In

• TSMC — one layer downstream; TSMC capex → ASML order book (multi-quarter lag). Both companies raised guidance in the same window (2026-07-15/16).
• Nanosheet GAA Transistor — EUV is what patterns the N2/A16 nodes.

Changelog

• 2026-07-16 — Entity created. Q2 2026 print folded in (primary from asml.com): €9.33B net sales / 54.0% GM (both above guidance), FY26 guide raised to €43–45B/54–56% (+20.5% midpoint since the 20-F), Q3 guide €11–12B. Beat engine = Installed-Base/service, not new systems. Capacity +30% Low-NA EUV for 2027 (transcript-attributed). Cross-linked to the TSMC entity and the lithography-economics frontier. No directional call.
