Investment Thesis

Top-5 global IGBT maker + world-class FA systems + defense electronics. RECORD FY2026: Revenue ¥5,894.7B (+6.8%), adj. OP ¥538.4B (9.1% margin), NI ¥407.7B (+25.8%) — structural margin improvement confirmed, not just cyclical. KEY CATALYST: MOU signed Mar 27, 2026 to merge power semiconductor business with Rohm + Toshiba Electronic Devices — combined entity would be world's #2 power semi behind Infineon. Denso withdrew competing Rohm bid Apr 28, 2026, clearing the path. FA China recovering: first profit increase in 9 quarters (Q1 FY2026). Defense segment growing (Japan 2% GDP defense target). Near-zero debt (D/E 8%) with ¥363.8B net cash provides full optionality for JV structuring.

Risk

Peak earnings risk: PE 32.85x on record FY2026 margins (9.1%) — FA and power semi are inherently cyclical. If EV demand softens or China FA disappoints, earnings could compress materially. JV execution risk: No definitive agreement, no agreed valuation, multi-jurisdiction regulatory review — deal could take 2-3 years or fail entirely. ¥100B "Next-Stage Support Program" (voluntary retirement) restructuring cost in FY2026 signals the margin improvement required significant organizational disruption. Stock already +117-144% in 52 weeks — much of the re-rating likely captured.

Monitoring Trigger

JV: definitive agreement announcement (expected H2 2026) = upgrade trigger. Earnings: if FY2027 Q1 adj. OP margin sustains above 8.5%, thesis strengthening. EV demand: if global EV sales growth decelerates to <15% YoY for 2 consecutive quarters, flag power semi cycle peak risk. China FA: monitor quarterly segment OP — if recovery stalls after Q1 bounce, reduce weight.
