Investment Thesis
Direct transformer bottleneck play. Power transformer lead times at 128+ weeks. FY2026 actuals (Mar 2026): Revenue ¥326.2B (+8.3%), OP ¥27.1B (+26.1% — MASSIVE BEAT vs ¥20B guidance), NI ¥23.6B (+27.8%). OP margin expanded to 8.3% (from 7.1%). FY2027 guidance: Revenue ¥355B (+8.8%), OP ¥29B (+6.9%). Numazu transformer expansion: ¥16B → 1.5x capacity, 2028 completion on track. Meiden America SC plant expansion ($9.2M) completed. Japan utility grid ¥150B+ committed. CAUTION: Orders declined -6.6% YoY to ¥358.2B; Shiller PE at 97th percentile of 10-year history.
Risk
1) VALUATION RISK: Shiller PE 35.75 at 97th percentile of 10yr history (median 18.15). Stock priced for continued multi-year expansion. 2) Order decline: FY2026 orders ¥358.2B (-6.6% YoY from ¥383.6B) — if order intake continues declining, revenue growth stalls FY2028+. 3) FY2027 NI guided DOWN to ¥22B from ¥23.6B actual (-6.9%) — possibly higher taxes or non-operating charges. 4) Toshiba T&D expanding domestic capacity — potential market share pressure. 5) Iran war geopolitical risk (TS signal) → Japanese utility capex uncertainty.
Monitoring Trigger
FY2027 Q1 results (Aug 2026): If order intake recovers above ¥100B (quarterly), HOLD at 12%. If order intake <¥80B for 2 consecutive quarters, TRIM to 8% (thesis weakening). If Shiller PE normalizes below 25x (price correction), ADD to 15%. Numazu 2028 completion on schedule — verify annually.

Supply Chain Evidence
| Evidence | Customer | Product | Detail |
|---|---|---|---|
| confirmed | TEPCO / Japanese utilities | Power transformers, switchgear | Core domestic customer. FY2026 Power Infrastructure segment revenue grew. Japan utility grid ¥150B+ investment committed 2026+. |
| confirmed | US utilities (via Meiden America) | 123 kV SF6-free vacuum circuit breakers | SC plant expansion, $9.2M investment, completion May 2026 |
| probable | Japan data center grid (indirect) | Grid-level transformers for DC power connections | No named contracts; thesis relies on utility channel demand from DC buildout |
