Shindengen Electric Manufacturing Co., Ltd.
6844.TMEDIUMScore: 30.5Two-Wheeler Power Electronics / PCU · Weight: 4%· Data as of 2026-05-06
Investment Thesis
Honda-affiliated (largest shareholder ~26%) maker of Power Control Units (PCU) for electric motorcycles — the brain that controls motor drive, battery state, and regeneration in Honda e-motorcycles. As Honda ramps from ~50K to 1M+ e-motorcycle units by 2030 (new India factory 2028, UC3 launch Vietnam/Thailand 2026), Shindengen is the captive PCU supplier with no announced substitution risk. Small cap (¥33.4B) with step-function demand coming.
Risk
Extreme Honda customer concentration (~70%+ revenue). Honda could vertically integrate PCU in-house. PE 30.8x high for keiretsu supplier — priced for execution. PB/ROE not confirmed from Tier 1-2 sources — data gap flagged. Small float limits liquidity.
Monitoring Trigger
If Honda announces e-motorcycle unit target >500K/yr before 2028, add. If Shindengen announces capacity expansion for EV PCU, add. If Honda files patent for in-house PCU, reduce.
