Lasertec is the actinic EUV mask-inspection gatekeeper—temporarily cyclically soft in FY2026, but structurally positioned for the High-NA EUV and 2nm super-cycle.
Overview
Lasertec (6920.T) is a structurally indispensable semiconductor metrology supplier and the global monopolist in actinic EUV photomask inspection—an enabling technology for manufacturing at 5nm, 3nm, and the forthcoming 2nm node. Its ACTIS and ABICS platforms inspect masks using the actinic 13.5nm wavelength (the same used in EUV lithography), enabling detection of ultra-fine printable defects that DUV optical tools cannot see and that e-beam tools cannot inspect fast enough for high-volume production. The company runs a capital-light “fab-lite” model, outsourcing assembly to specialized partners and concentrating internal resources on engineering: ~70% of staff are engineers and R&D typically runs ~5–10% of sales. Revenue is dominated by the semiconductor segment (H1 FY2026: ~¥98.3B of ~¥128.3B), supplemented by a growing, stabilizing aftermarket/services stream (H1 FY2026 services: ~¥27.9B, +25.7% YoY). After a record FY2025 peak (sales ~¥251.5B; operating margin ~48.8%; ROE ~46.9%), Lasertec is entering a cyclical digestion phase in FY2026 with modest H1 softness and consensus calling for a ~10% revenue decline, before an expected recovery driven by fab-level A200HiT demand and High-NA EUV adoption toward the late 2020s.
