Investment Thesis
Japan's aging grid replacement oligopoly (3 domestic players capable of 275kV XLPE cable). FY2026: Revenue +16.8% to ¥277.74B, OP +30.5% to ¥27.32B (record), NI +65.3%. e-Ribbon optical fiber 7x capacity by FY2030 (¥20B investment) captures AI data center wave. SFCC fully consolidated (March 2026) + TOTOKU acquisition adds semiconductor/EV precision wire. FY2026 dividend +64% to ¥223/share; ¥250 guided FY2027 (DOE 5%+ target). ¥400B aging cable replacement market through 2045 with only 3 capable domestic suppliers.
Risk
1) FY2027 guidance deceleration: OP +4.3% vs FY2026's +30.5% — guidance miss risk from copper cost headwinds + capex absorption. Stock -10.7% on May 14 earnings day. 2) CAPACITY HANGOVER: All 4 major cable makers expanding simultaneously (Furukawa ¥100B HVDC, Sumitomo ¥40B, Fujikura ¥300B total) — optical fiber oversupply risk by 2028-2030. 3) SWCC not in major offshore HVDC consortium (Furukawa leads RIGHT Project) — competitive gap for deep-water submarine cable. 4) Net debt ¥35.4B with ¥80B M&A envelope — leverage risk if demand softens.
Monitoring Trigger
Q1 FY2027 (Aug 2026): if revenue ≥¥75B (¥325B/4), guidance tracking — HOLD. If aging cable replacement contract wins announced (utils naming SWCC), ADD signal. If optical fiber oversupply pricing starts (checks vs Fujikura/Furukawa), TRIM. If FY2027 OP guidance raised mid-year, ADD to 7%.

Update History
FY2026 results (May 14): OP +30.5% to ¥27.32B (record), NI +65.3%, revenue +16.8%. FY2027 guided OP +4.3% (guidance miss → stock -10.7%). PE compressed 25.39→22.2, PB 4.14→3.92. SFCC 100% acquired March 2026. e-Ribbon 7x optical fiber expansion announced Feb 2026. Capacity hangover FLAGGED: all 4 cable makers expanding simultaneously. HOLD.
