ASML

ASML — ASML

TL;DR

Demand exceeds ASML’s capacity — that’s the FundaAI verdict heading into 1Q26 results and it maps cleanly to the N3 shortage story.12 Three demand waves converge: (1) TSMC revising EUV procurement up on advanced-node capacity shortage; (2) Chinese DUV resilience (CXMT aggressive procurement); (3) memory capex resurging (SK Hynix $8B EUV order, Micron capex revision up, Samsung reportedly procuring ~20 EUV machines).1 A 1000+ W light-source R&D disclosure could extend the cost-per-chip improvement runway; xLight / Free Electron Laser is a long-dated threat to LPP but not near-term.3

Business

Monopoly supplier of EUV lithography (Low-NA and High-NA) to leading-edge logic + memory. Also supplies DUV (immersion + dry), metrology, computational lithography. Customers: TSMC, Samsung, Intel, SK Hynix, Micron, CXMT (DUV only under export controls), GlobalFoundries, Tower, UMC. Each LPP EUV scanner ships with its own tin-based laser-produced-plasma light source; ASML has disclosed R&D unlocking 1000+ W output (>300 wph at today’s 30 mJ/cm² dose).3

Thesis

  • Capacity-constrained through 2026. FundaAI: “the only headwind is ASML’s capacity.” TSMC upward revision to EUV procurement + memory capex pull-in means ASML’s bookings/shipment trajectory is set; execution is about delivery cadence, not demand.1
  • Memory restart drives a second EUV leg. SK Hynix $8B order + Micron capex revision higher + reported Samsung 20-machine procurement signal that DRAM/HBM makers are committing meaningfully to EUV beyond leading-edge logic.1
  • China DUV resilience. CXMT’s aggressive DUV procurement shows demand is real even under the export-control regime; MATCH Act remains in early legislative stages with “limited impact on 2026.”1
  • Intel + Samsung Foundry recovery. A business-recovery at the #2 and #3 foundries is additive to ASML bookings, not cannibalistic to TSMC — trailing-edge EUV/DUV + advanced-node reengagement.1
  • Longer light-source runway than the bear case assumes. LPP today hits ~500 W / 6% efficiency; ASML roadmap to 600-800 W, and a Feb-2026 Reuters disclosure signals 1000+ W unlocked in R&D — 50% more chips by 2030 was the framing. Extends the cost curve and buys time against FEL alternatives.3

Risks

  • Cost curve bending. Chipstrat’s Photons as a Service lays out the structural problem: higher NA + higher dose per node = fewer wafers/hour. If xLight’s Free Electron Laser light source (backed by $150M CHIPS LOI, partnered with Fermilab) ships at scale, it challenges the LPP economic model — though xLight plugs into ASML scanners rather than replacing them. Multi-year risk, not near-term.3
  • Export controls escalation. MATCH Act progressed, though early stage; a tightening of China DUV access would dent a segment the corpus flags as a 2026 tailwind.1
  • Memory capex volatility. DRAM capex decisions are pro-cyclical; any consumer-demand shock that loosens HBM4 pin-speed pressure could pull forward cancellation risk on new EUV orders.2
  • Customer concentration. TSMC is the dominant EUV customer; any disruption to TSMC ramp (power, packaging, Taiwan risk) reduces ASML near-term shipments.
  • High-NA (EXE:5000) slow adoption. High-NA boosts resolution but cuts throughput at higher dose; if customers delay ramp or stretch Low-NA with multi-patterning, ASML’s ASP mix disappoints.3

Second-order reads

  • 2026-03-12 — SemiAnalysis, Great AI Silicon Shortage — TSMC capex smashing 2025 records in 2026; cleanroom-space-constrained, not equipment-constrained. Positive for ASML shipment cadence into 2H26.2
  • 2026-03-24 — SemiAnalysis, Nvidia Inference Kingdom Expands — Nvidia’s TSMC N3/CoWoS allocation is the industry’s binding resource; every new Nvidia product generation tightens EUV demand one node further down.8
  • 2026-02-09 — SemiAnalysis, CPUs Are Back — hyperscaler Arm CPUs add a class of N3 customers; broadens ASML’s addressable demand base.9
  • 2026-01-01 — SemiAnalysis, CPO book scaling — more complex packaging + more chip content per system = more wafer starts per unit of compute → ASML-positive.10

Valuation & positioning

Pending. The FundaAI piece frames this as “demand > capacity”; bookings trajectory rather than multiples is the setup. Revisit when 1Q26 print lands (expected mid-April 2026).
