Type: Deep Evolution
Stocks updated: Nitto Boseki (3110.T), Daikin Industries (6367.T), Rohm (6963.T)
Report date: 2026-06-04
Method: T-Glass Supply Chain Bottleneck Analysis + ReACT verification
Executive Summary
Three stocks evolved today spanning AI packaging materials (Nitto Boseki), data center cooling infrastructure (Daikin), and power semiconductor consolidation (Rohm). All three had stale data from April 2026; May earnings have now been incorporated. Key findings: Nitto Boseki's T-glass monopoly is strengthening with dual price+volume expansion; Daikin's DC cooling thesis is real but still below the concept-stock revenue threshold; Rohm's JV talks are materially delayed and the stock is priced well above analyst fundamental consensus.
1. Nitto Boseki (3110.T) — T-Glass Monopoly
Theme: AI / Restocking
Thesis status: HOLD
Data date: 2026-06-04 (previously 2026-04-21)

| Metric | FY2025 Actual | YoY |
|---|---|---|
| Revenue | ¥118.2B | +8.4% |
| Operating Profit | ¥20.8B | +26.6% |
| Net Income | ¥41.8B | +225% (asset sales — not recurring) |

Key Developments
Supply chain confirmed:
- **Nan Ya Plastics partnership** (confirmed, Nov 2025): Nan Ya handles 20% of Nittobo's specialty weaving by 2027, providing near-term supply relief while Fukushima ramps. Source: TrendForce, 2025-11-28
- **Nvidia, Google, Amazon competing for supply** (confirmed, Nov 2025): Named as direct customers competing for Nittobo T-glass. Order books full through end-2026. Source: TrendForce, 2025-11-24
- Ibiden ABF substrates (probable): T-glass is explicit spec requirement for ABF substrates; no public contract.
Pricing & Volume:
- T-glass price raised +20% August 2025; JPMorgan models +25% pricing from 2026 onward
- Shipment growth guided +20-30% YoY — rare dual price+volume expansion simultaneously
- Nvidia GPU substrate area growing from 3,190mm² (Hopper) to ~8,000mm² (Rubin) + more layers → multiplies T-glass content per chip
Capacity: Fukushima factory (¥15B, 3x capacity, METI ¥2.4B subsidy) production start Jan-Mar 2027. Nan Ya partnership provides interim relief.
Analyst actions: JPMorgan upgraded to Overweight (T-glass pricing +25% from 2026); Morgan Stanley upgraded to Overweight. 5/0 Buy/Sell ratio. 5-for-1 stock split effective June 29, 2026.
Anti-Pattern Check
| Anti-Pattern | Status |
|---|---|
| Peak Earnings Trap | CLEAR: OP +26.6% with FY2026 +24.9% guided. NI distorted by asset sales; operating trend intact. |
| Concept Stock | CLEAR: T-glass ~20-30% of electronic materials (~40% of revenue) → well above 5% threshold |
| Capacity Hangover | FLAG 2027+: 3x Fukushima + Nan Ya + competitor qualifications could flip supply. Not imminent. |
Risk Flags
- Competitor qualification 2027+: Apple qualifying Grace Fabric Technology + Taiwan Glass; Chinese quartz cloth reportedly passed Nvidia certification at small scale. Structural watch for 2027+.
- Intel glass-core substrate: Bypasses T-glass entirely for Xeon 6+ — medium-term threat to non-GPU packaging addressable market.
- Capacity hangover 2027+: If 3x Fukushima + Nan Ya + alternatives all materialize while AI server demand plateaus.
Inversion
Thesis breaks if: Competitor achieves full-scale Nvidia certification for T-glass alternative (Apple+Grace Fabric or Chinese quartz cloth at volume), OR Fukushima ramp delayed >6 months, OR AI server demand plateaus causing T-glass pricing to reverse.
2. Daikin Industries (6367.T) — AI Data Center Cooling
Theme: Data Center Ecosystem
Thesis status: HOLD
Data date: 2026-06-04 (previously 2026-04-14)
FY2026 Actuals (Year ended March 31, 2026 — announced May 12, 2026)
| Metric | FY2026 Actual | YoY |
|---|---|---|
| Revenue | ¥5.02T | +5.5% (record) |
| Operating Profit | ~¥435B | +5% (record) |
| Net Income | ¥275.2B | +4.0% (record) |
| OP Margin | 8.7% | |
| Tariff impact absorbed | ¥42B | fully absorbed |
| FX headwind | ¥71.5B | fully absorbed |

FUSION 30 Strategic Plan (announced May 12, 2026)
- FY2028 target: 10% operating margin (vs 8.7% today), 12% ROE (vs 9.26%)
- FY2030 aspirational: 12% OP margin, 15% ROE
- Data centers explicitly named as core growth pillar

Supply Chain Confirmed
| Customer/Entity | Product | Evidence | Date |
|---|---|---|---|
| Delta Electronics | CDU co-development MOU (ASEAN-Oceania, 100kW–3,000kW rack density range) | Confirmed | Daikin PR, 2026-05-11 |
| Chilldyne (subsidiary) | Negative-pressure liquid CDU — eliminates leak risk for GPU racks | Confirmed | PR Newswire, 2025-11-04 |
| DDC Solutions (subsidiary) | Modular high-density server rack cooling cabinets (white-space layer) | Confirmed | DDC Solutions, 2025-08 |
Critical gap: No named hyperscaler contracts (AWS, Google, Microsoft) publicly confirmed. Daikin uses "hyperscale" terminology in marketing.

Anti-Pattern Check
| Anti-Pattern | Status |
|---|---|
| Peak Earnings Trap | MILD FLAG: FY2026 set records in revenue + OP + NI. However, FUSION 30 growth path is credible and tariff headwinds become neutral in FY2027. Not a cyclical peak. |
| Concept Stock | FLAG: DC cooling ~3-5% of group revenue — at the concept-stock threshold. Products are real (not vaporware) but revenue not yet material. |
| Capacity Hangover | MILD FLAG: Vertiv, Schneider, Mitsubishi, and Daikin all expanding DC cooling simultaneously. Market large enough for multiple winners (projected CAGR 16.9% to 2036) but pricing pressure risk rises. |
Risk Flags
- Concept stock threshold: DC cooling at ~3-5% of group revenue — investors are paying for optionality not yet in earnings. Named hyperscaler contracts absent.
- Vertiv lead: USD 15B order backlog (+109% YoY), 3-5yr head start in hyperscaler relationships. Daikin competes for investor capital against a pure-play with better visibility.
- Valuation: At PE 25.16x with concept-stock element, any guidance miss in FY2027 would pressure the stock.
Inversion
Thesis breaks if: Q1 FY2027 (Aug 2026) DC cooling revenue stagnates AND no named hyperscaler contract materializes AND FY2027 full-year guidance disappoints vs analyst consensus.
3. Rohm (6963.T) — SiC Power Semiconductor + JV
Theme: EV / Restocking
Thesis status: HOLD (elevated caution — do not add at current levels)
Data date: 2026-06-04 (previously 2026-04-20 in restocking, 2026-05-03 in EV)
FY2025 Actuals (Year ended March 31, 2026 — announced May 12-13, 2026)
| Metric | FY2025 Actual | vs. Nov 2025 Guide |
|---|---|---|
| Revenue | ¥481.1B | Beat (¥460B guide) |
| Operating Profit | ¥10.8B | Beat (¥5B guide) |
| Net Income | -¥158.4B | Miss (¥9B guide) — SiC impairment |
| FY2026 OP Guidance | ¥30.0B | +176% from FY2025 |
| FY2026 Revenue Guide | ¥510.0B | +6.0% |
Source: Rohm FY2025 決算短信, May 12, 2026; BigGo/TDnet, 2026-05-13
Note: The ¥158.4B net loss (vs. previously known ¥57B FY2024 loss) is a kitchen-sink impairment on SiC fixed assets driven by BEV market slowdown and Chinese competition. Post-impairment, depreciation burden falls sharply — the ¥30B OP recovery in FY2026 is mechanically credible.
JV Status — DELAYED
- March 27, 2026: MoU signed by all 5 parties (Rohm, Toshiba, Mitsubishi Electric, JIP, TBJH). Combined power semi global rank would be #2 (~9.7-11% market share, above onsemi).
- April 28, 2026: Denso withdrew ¥1.3T acquisition bid. Rohm preferred JV path.
- May 15, 2026: Rohm president warned JV talks "more complex and slower than initially expected." No formal equity structure yet.

Anti-Pattern / Guardrail Flags
| Check | Status |
|---|---|
| P/B at cyclical peak | FLAG: 2.56x vs historical 1.3-1.4x norm. Above estimated 80th percentile. |
| EV validation | FLAG: Analyst consensus PT ¥2,944 vs market ¥5,400+ = >30% divergence. |
| Still loss-making | FLAG: ROE negative; NI still in loss; first clean profitable quarter not yet achieved. |
| JV speculation premium | FLAG: Stock 3x'd from lows on M&A; primary catalyst (Denso bid) withdrawn. |
Risk Flags
- JV delay risk: Three-party integration of Rohm + Toshiba TDSC + Mitsubishi Electric involves complex overlapping product lines, manufacturing footprints, and corporate cultures. Rohm president acknowledged complexity; no timeline confirmed.
- P/B at historical peak: At 2.56x, well above pre-crisis 1.3x norm. Risk of mean reversion if JV stalls.
- Analyst consensus -47% from market: Fundamental analysts not buying the JV/M&A premium at current levels.
- SiC impairment worsened: FY2025 NI -¥158.4B worse than FY2024 -¥57B. Management credibility gap.
Inversion
Thesis breaks if: JV talks formally collapse, OR FY2026 OP misses ¥30B target by >30%, OR SiC impairment charge recurs in FY2026, OR Chinese competitor wins a major EV platform customer from Rohm.
