Investment Thesis

MONITORING TRIGGER HIT: Tomari Unit 3 NRA safety review approved July 30, 2025 — Japan's nuclear regulator formally cleared the 912MW reactor after 12 years of review. Restart target confirmed 'as soon as possible in 2027' (seawall completion early 2027). PBR 0.46x — still below book despite +32% 12-month run. Forward PE 6.74x reflects earnings normalization after Q4 FY2026 loss. Power supplier for SoftBank Tomakomai DC (300MW, Phase 1 50MW opening FY2026) and Rapidus 2nm IIM-1 fab (Chitose, Hokkaido — mass production target 2H FY2027). Hokkaido grid strain from DC boom = structural demand tailwind.

Risk

1) Tomari Unit 3 restart still requires seawall completion (early 2027) AND local consent — ongoing lawsuit (filed 2011) could delay. 2) D/E 4.17x — highest leverage in portfolio; ¥192B market cap vs huge debt. 3) Q4 FY2026 was a loss (-¥4,824M); FY2026 NI ¥44B but forward PE implies ¥28B NI — earnings to normalize lower. 4) Regulated utility: upside capped by tariff review cycles. 5) Stock already up +32.93% in 52 weeks; near-term catalysts now partially priced.

Monitoring Trigger

TRIGGER STATUS: Tomari Unit 3 NRA approval CONFIRMED (July 2025) → ADD signal triggered. Next: seawall completion confirmation (early 2027) → restart countdown begins. If SoftBank Phase 1 50MW DC opens on schedule (FY2026) with HEPCO power, ADD to 7%. If D/E exceeds 5.0x OR dividend cut, EXIT regardless of nuclear timeline. If NRA Units 1/2 also cleared AND Rapidus power contract announced, ADD to 9%.
