Investment Thesis
#1 global wet cleaning (single-wafer). 83% revenue from SPE. Foundry 52% of SPE (TSMC 2nm/A16 ramp). Forward PE 17.9x — cheapest Japan semi equipment stock (TEL 32x, Advantest 42x). Near-zero debt (D/E 0.01), ¥180B net cash. NAND recovery in FY2027 is free option not priced in (currently only 3% of SPE). Advanced packaging entry via Nikon hybrid bonding acquisition expands TAM.
Risk
China is 39% of sales — biggest geopolitical risk. FY2026 is cyclical down year (-14% operating income). ACM Research gaining share in China domestic market. Non-disclosure of order backlog creates forecasting opacity.
Monitoring Trigger
If China export controls expand to wet cleaning tools for sub-28nm, downgrade. If NAND capex recovers (Kioxia/Samsung expansion orders), upgrade to STRONG BUY.
Key Dates
Update History
TSMC confirmed supplier (Excellence Award Dec 2024). ROE updated 19.8%→22.4%. Dividend cut ¥308→¥280 (yield 1.3%→2.5%). Supply chain upgraded. Recovery thesis intact.
Deep DD update: cheapest Japan semi equip on forward PE (17.9x vs TEL 32x). China 39% risk flagged. NAND upside optionality. Advanced packaging entry.
