Investment Thesis
Turnaround confirmed: FY2026 NI guidance ¥77B (2.7x prior year). Semiconductor & Electronic Materials hit record core OP ¥109.1B in FY2025 (+47% YoY). Q1 FY2026 core OP ¥33.6B (2.3x YoY) with EBITDA margin 18.2% (approaching 20% target). H1 guidance raised 40% on core OP (¥74B). Back-end AI materials (HBM bonding, CoWoS slurries) at quarterly record. TSMC 2025 Excellent Performance Award confirmed supplier status. Local production at TSMC Kumamoto. JOINT3 consortium (27 members) developing next-gen panel-level interposers. ¥300B semiconductor materials investment over 3 years.
Risk
1) Stock ¥17,200 trades 21% ABOVE analyst consensus target ¥14,243 — near-term reversion risk. 2) Q1 FY2026 revenue missed estimates by 6.67% despite strong core OP — demand mix shift or timing? 3) Forward PE ~40x (¥3.11T mcap / ¥77B NI guidance) — premium already priced. 4) Middle East uncertainty cited by management as reason to maintain full-year guidance despite raised H1 — macro risk. 5) HBM demand could be front-loaded if AI capex cycle normalises.
Monitoring Trigger
If H2 FY2026 core OP guidance stays at raised levels at Q2 results (Aug 2026), HOLD. If stock corrects to ¥13,000-14,000 (near analyst consensus), ADD to 9% — margin turnaround thesis intact. If revenue beats and EBITDA margin exceeds 20% target, thesis UPGRADED. If AI back-end materials demand slows for 2 quarters, TRIM to 5%.
