Investment Thesis
Fabless custom SoC on TSMC 3nm/A14 for AI data center and automotive. FY2026 beat by 5.7% — revenue ¥200.8B, strong sequential recovery (Q1 ¥34.6B→Q4 ¥58.7B). FY2027 guide: ¥215B (+7.1%). Confirmed TSMC A14 tape-out H2 2026 + Arm Total Design partnership. 52% gross margin. Near-zero debt. AI hyperscaler capex $700B in 2026 = structural tailwind.
Risk
Net margin compressed 10.4%→4.3% in FY2026 — this is the key risk. Cause not fully disclosed (mix shift, ramp costs?). No named hyperscaler customer. FY2027 recovery to ¥10B net profit must deliver. Revenue still below FY2025 peak of ¥221.25B.
Monitoring Trigger
May 14 FY2026 full results — watch margin explanation and FY2027 guidance confirmation. TSMC A14 tape-out completion H2 2026 = technology risk cleared. Any named hyperscaler design win = significant upgrade catalyst.
