Investment Thesis
Global #1 HVAC maker that assembled a full end-to-end AI data center cooling stack in 12 months: DDC Solutions (rack cabinets, Aug 2025) + Chilldyne (patented negative-pressure CDU eliminating leak risk for GPU racks, Nov 2025) + Daikin chillers/AHUs (grey space). FY2026 record: revenue ¥5.02T (+5.5%), OP ~¥435B (+5%), NI ¥275.2B (+4%). Absorbed JPY 42B tariff impact + JPY 71.5B FX headwind in FY2026 through pricing/cost actions. FUSION 30 plan targets 10% OP margin by FY2028 (vs 8.7% today) and 12% ROE by FY2028 (vs 9.26%). Delta Electronics MOU (May 2026): CDU co-dev for ASEAN-Oceania covering 100kW to 3,000kW rack densities — indirect hyperscaler access via Delta's customer base. USD 163M R&D test lab (Plymouth MN, 9 test cells) completion 2027.
Risk
1) DC cooling is ~3-5% of group revenue — at concept-stock threshold; investors are paying for optionality not yet in earnings. 2) No named hyperscaler contracts publicly confirmed — 'hyperscale' is positioning, not signed revenue. 3) Vertiv has 3-5yr head start with USD 15B backlog; Schneider/Mitsubishi also expanding — competitive intensity rising. 4) PE 25.16x is fair quality multiple but not cheap; any FY2027 guidance miss could reprice. 5) FX sensitivity: JPY 71.5B FX headwind absorbed in FY2026; JPY appreciation would be ongoing drag.
Monitoring Trigger
UPGRADE trigger: Q1 FY2027 (Aug 2026) discloses (a) explicit DC cooling revenue segment >¥100B, OR (b) named hyperscaler contract win, OR (c) FY2027 guidance above analyst consensus — ADD to 8%. TRIM trigger: two consecutive quarters of DC cooling revenue stagnation, or PE >28x without fundamental upgrade.

Supply Chain Evidence
| Evidence | Customer | Product | Detail |
|---|---|---|---|
| confirmed | Delta Electronics | CDU (Cooling Distribution Unit) co-development and go-to-market for ASEAN-Oceania | MOU signed May 11, 2026 by Daikin Holdings Singapore + Delta Electronics. Covers rack densities 100kW–3,000kW. Delta is world's largest CDU manufacturer; MOU gives Daikin indirect hyperscaler channel access.[source](2026-05-11) |
| confirmed | Chilldyne (wholly-owned subsidiary) | Negative-pressure liquid CDU — patented leak-free cooling for GPU server racks | Acquired Nov 4, 2025. Negative-pressure design eliminates catastrophic leak risk for USD 30K+ GPU cards. Proven GPU cluster deployments since 2014. Technical differentiator vs positive-pressure competitors.[source](2025-11-04) |
| confirmed | DDC Solutions (wholly-owned subsidiary) | Modular high-density server rack cooling cabinets (white-space layer) | Acquired Aug 2025. Provides the server-room rack-level layer of the end-to-end DC cooling stack: grey-space (Daikin chillers) → white-space (DDC racks) → chip-level (Chilldyne CDU).[source](2025-08) |
