Layer 5 · 6920 — Lasertec Corporation
Live: JPY 43,770 · Earnings (last): Q4 FY26 EPS/rev below consensus · Next earnings: Aug 2026 · Conviction: 4/10
Bottleneck context
Lasertec holds the actinic EUV mask inspection monopoly — sole-source supplier of the inspection tools mask shops must use to qualify EUV mask quality. Genuine Layer 5 monopoly franchise that should be Tier A on structure alone.
Why Tier C
Q4 print missed both EPS and revenue. -16.4% reaction confirmed the disappointment. Order timing in this business is famously lumpy — single-tool orders can swing quarters by 20%. HBM4 mask commentary from management was vague and is flagged needsmanualcheck. Flipped B to C on the print disappointment; structurally this is a Tier A monopoly, tactically this is in the penalty box.
Watch trigger
Stabilization in order book with 2-3 sequential quarters of clean order flow, OR explicit HBM4 mask-inspection design-in disclosure.
Position guidance
No position. Best-in-class structural name in tactical penalty box — patient watch-only. Strong B candidate on a recovery print.
