Investment Thesis
100% monopoly in actinic EUV mask blank inspection. 46.1% op margin. Co-dependent with ASML — ACTIS A200HiT launched Oct 2025 extends monopoly to High-NA EUV. Intel 2025 & 2026 EPIC Supplier Awards confirm customer lock-in. Non-negotiable for every 5nm-and-below chip.
Risk
PE 44x premium. Q3 FY2026 EPS missed consensus by 25.9% — execution risk. TSMC N2 volume delay = direct revenue impact. Short-seller overhang persists.
Monitoring Trigger
Monitor ASML EXE:5000 High-NA shipment volumes (each unit = new Lasertec inspection need). If TSMC N2 ramp falls below 5K wafer/month by Q4 2026, reassess FY2027 guidance.
Key Dates
Update History
Added Intel as 3rd confirmed supply chain customer (2025+2026 EPIC awards); op_margin updated 48.7%→46.1% (Q3 FY2026 actuals); key dates refreshed; thesis updated for High-NA EUV ACTIS A200HiT
