DD Evolution: 9434.T / 6988.T / 6506.T

Date: 2026-06-07 | Type: Evolve | Stocks: 3

Executive Summary

This evolve round updated three stocks with the oldest data in the portfolio. Key findings:

• 9434.T SoftBank Corp: UPGRADED to MEDIUM-HIGH — FY2025 record results (Rev ¥7.04T, NI ¥550.8B), first dividend increase in 5 years, GPU Cloud Oct 2026, supply chain filled from 0→7 links (NVIDIA, Oracle, OpenAI, Ericsson, Qualcomm, Cosmos Lab).
• 6988.T Nitto Denko: HOLD — CRITICAL thesis correction: T-glass attribution was wrong (T-glass = Nittobo/3110.T, not Nitto Denko). Actual thesis: semiconductor process tapes (NF735 for HBM/2.5D/3D packaging) + optical films + IBM JDA.
• 6506.T Yaskawa Electric: HOLD — Dash 35 plan confirmed (OP ¥100B / 15.4% margin by FY2029). NVIDIA Physical AI partnership and SoftBank MOU captured. July 9 US tariff expiry is a BINARY risk event.

9434.T — SoftBank Corp (UPGRADED: MEDIUM → MEDIUM-HIGH)

Thesis Update

SoftBank Corp is executing a credible transformation from pure telco to Japan's sovereign AI infrastructure platform.

FY2025 results (ended March 31, 2026) — All four targets beaten (after two upward revisions):

• Revenue: ¥7,038.7B (+8% YoY, record high)
• Operating Income: ¥1,042.6B (+5% YoY)
• Net Income: ¥550.8B (+5% YoY, record high)
• Adjusted FCF: >¥600B (target achieved); Capex: <¥330B (target achieved)

FY2026 Guidance: Revenue ¥7,500B (+7%), OP ¥1,100B (+6%), NI ¥560B (+2%)

New Medium-Term Plan (FY2026–FY2030):

• Operating Income target: ¥1.7T by FY2030
• Net Income target: ¥700B by FY2030
• Dividend: ¥8.80 FY2026 (first increase in 5 years), targeting ¥10/share by FY2030

Key Developments Since Last Review (April 2026)

1. IDC Frontier absorbed April 1, 2026 — Integrated DC+AI platform complete

2. Tomakomai Hokkaido DC: ~60-70% complete as of Feb 2026; Phase 1 (50MW) targeting FY2026 operational; full 300MW+ planned

3. AI Data Center GPU Cloud (October 2026 launch): NVIDIA GB200 NVL72, Infrinia AI Cloud OS, sovereign AI positioning for Japanese enterprises

4. Osaka Sakai AX Factory: 140MW AI DC + 110 ExaFLOPS compute announced; former Sharp LCD plant

5. Crystal Intelligence (SB OAI Japan JV): First deployer across 2,500 internal systems; commercial rollout to enterprises ongoing

Supply Chain (0 → 7 links)

Metrics Update

Key Upcoming Catalysts

• Jul 2026: Q1 FY2026 earnings — Enterprise segment +20% trajectory check
• Aug 2026: Tomakomai Phase 1 (50MW) operational status
• Oct 2026: AI DC GPU Cloud commercial launch (NVIDIA GB200); Oracle Alloy West Japan
• FY2026: Battery factory mass production start

Risk Flags

• GUARDRAIL — P/B 3.51x: Elevated for telecom sector. Override justified: DC transformation (IDC Frontier, GPU Cloud, Tomakomai, Osaka Sakai) represents structural shift from pure telco to AI infrastructure operator. FY2025 record results confirm execution.
• CONCEPT STOCK WATCH: DC/AI revenue still <10% of ¥7T total. Not flagged as concept stock (telco is the stable core funding DC buildout), but monitor for DC segment revenue disclosure to confirm thesis is materializing.
• Thesis breaks if: Tomakomai construction delayed >6 months past FY2026 target; GPU Cloud <50% utilized by March 2027; D/E exceeds 4.0x without revenue offset.

6988.T — Nitto Denko Corporation (HOLD — Thesis Corrected)

CRITICAL CORRECTION

The original thesis attributed T-glass manufacturing to Nitto Denko (6988.T). This is INCORRECT.

• T-glass (low-dielectric E-glass for AI PCB substrates) is made by Nittobo / Nitto Boseki (3110.T) — a completely separate company
• Nitto Denko (6988.T, 日東電工) makes optical polarizing films, semiconductor process tapes, and industrial adhesives
• The corrected thesis below replaces all T-glass references

Corrected Investment Thesis

Nitto Denko's legitimate AI investment case:

1. NF735 plasma dicing tape for HBM (HBM3/HBM3E), 2.5D/3D packaging at TSMC and Samsung → direct AI infrastructure exposure through wafer-level process consumables

2. IBM JDA (Sep 2025) for advanced chiplet packaging polymeric materials (warpage control, thermal management, crosstalk suppression) → R&D-stage upside confirmed by primary press release

3. Dominant OLED/LCD polarizing films (~71% oligopoly with Sumitomo Chemical + LG Chem) for Apple/Samsung → stable high-margin revenue base

FY2025 Results (ended March 31, 2026)

• Revenue: ¥1,028.2B (+1.4% YoY)
• Operating Profit: ¥183.6B (-1.1% YoY); OP Margin: 17.9%
• Net Income: ¥133.5B (-2.7% YoY); EPS: ¥197.20 (post 5-for-1 split basis)
• FCF: ¥84.7B (down from ¥102.8B prior year)
• Dividend raised: ¥60→¥64/share

FY2027 Guidance: Revenue ¥1,065B (+3.6%), OP ¥193B (+5.1%), NI ¥141B (+5.6%)

Supply Chain (corrected and expanded)

Metrics Update

Morningstar fair value estimate: ¥5,179 vs market ~¥3,115 (~66% upside)

Key Upcoming Catalysts

• Jul/Aug 2026: Q1 FY2027 earnings — semiconductor tape revenue growth and Optronics segment recovery
• 2026-2027: IBM JDA commercialization announcement (if R&D successful)
• Ongoing 2026: China export control escalation — formal restrictions on semiconductor materials exports would be a significant negative

Risk Flags

• CRITICAL: Thesis corrected — T-glass attribution removed. Prior MEDIUM conviction was based on incorrect company identification. Corrected thesis (semiconductor process tapes) is legitimate but narrower and less direct than a T-glass monopoly would have been.
• CHINA EXPORT CONTROL RISK: Nitto is on China's watch list. Asia-Pacific ~60% of revenue. Formal restrictions on semiconductor tape exports to Chinese chipmakers = material downside (HIGH severity).
• ROE below target: 12.2% vs 15% company goal. FCF declined ¥102.8B→¥84.7B YoY — rising capex intensity.
• Concept stock partial flag: True AI-adjacent revenue (HBM dicing tape, IBM JDA) is likely 10-20% of total — not <5% threshold, but not a pure-play AI company.
• Thesis breaks if: China formally restricts Nitto semiconductor material exports; NF735 loses TSMC/Samsung design wins to competitors (Lintec, Mitsui); Apple sources OLED polarizers from alternate suppliers.

6506.T — Yaskawa Electric (HOLD — Positive Bias)

Thesis Update

World's #1 servo motor maker (~30% global share) is transitioning to a Physical AI platform, anchored by the Dash 35 mid-term plan.

FY2025 results (ended Feb 28, 2026) — NI decline is FX/cost distortion, not structural:

• Revenue: ¥542.1B (+0.8% YoY)
• Operating Profit: ¥47.3B (-5.7% YoY); OP Margin: 8.7%
• Net Income: ¥35.2B (-38.2% YoY) — driven by FX translation losses + abnormal large low-margin projects (non-recurring)
• FCF: ¥11.8B (OCF ¥49.2B minus capex ¥37.4B)

FY2027 Guidance: Revenue ¥580B (+7%), OP ¥60B (+27%), NI ¥47B (+33%)

Dash 35 Mid-Term Plan (May 22, 2026) — CONFIRMED

• FY2029 targets: Operating Profit ¥100B (2.1x FY2025), Operating Margin 15.4% (vs 8.7% today)
• Vision 2035: OP Margin 20%+, Dividend Payout Ratio 40%+
• Humanoid robots: R&D stage — no unit/revenue targets disclosed; Tokyo Robotics acquisition (Jul 2025) for actuator development; CEO: "commercial value in 2-3 years"
• Primary KGIs: Operating profit and operating margin (most important metrics to track)
• Sources: Dash 35 PDF, Vision 2035 PDF

Physical AI Differentiation — Confirmed

1. NVIDIA MOTOMAN NEXT (GTC 2026, March 2026): Integrates Isaac Manipulator (zero-shot manipulation), Omniverse (digital twin commissioning), Jetson (real-time AI inference) — confirmed press release

2. SoftBank MOU (December 1, 2025): Physical AI robots for office/hospital/school using AI-RAN + VLA model; demonstrated at iREX 2025

3. Tokyo Robotics acquisition (July 1, 2025): Humanoid actuator R&D (Waseda spinout); developing wheeled humanoid with dual arms

Tariff Risk Assessment (MEDIUM)

• Americas revenue: ~18-20% of total (~¥94B in 9M FY2025)
• July 9, 2026 BINARY EVENT: 90-day US tariff pause expiry — 24% reciprocal tariff on Japan goods potentially resumes
• Mitigation: $200M+ US local manufacturing (Franklin, WI + Miamisburg, OH); management has incorporated tariff uncertainty into FY2027 guidance
• Worst case: ~4-5% revenue at risk; partially mitigated by local production ramp

Supply Chain (Updated)

*Note: GM/VW downgraded from "confirmed" to "inferred" — no direct press release confirmation found in 2025-2026 searches.*

Metrics Update

*PE TTM distorted by FY2025 NI collapse. Forward PE 29.16x on FY2027 EPS is most relevant.*

Key Upcoming Catalysts

• Jul 3, 2026: Q1 FY2026 earnings (May 31 quarter) — CRITICAL: confirm order-to-revenue acceleration; upgrade trigger if >¥140B quarterly revenue
• Jul 9, 2026: BINARY EVENT — US 90-day tariff pause expiry; 24% tariff reinstatement risk
• H2 2026: MOTOMAN NEXT Physical AI commercial launch + first bookings
• H2 2026: Kitakyushu factory ramp (+50% capacity); demand absorption test
• Oct 2026: Q2 FY2026/H1 FY2026 earnings — ¥580B revenue guidance tracking
• Dec 2026: iREX 2026 — Physical AI and humanoid actuator showcase

Risk Flags

• GUARDRAIL — Forward PE 29x: Well above Japan machinery average ~15x. Market is pricing full Dash 35 execution. Override justified: Dash 35 is confirmed and credible (¥100B OP = 2.1x recovery from depressed FY2025 base, not speculation). However, any execution shortfall = significant multiple compression.
• GUARDRAIL — FCF growth cap: FCF from ¥11.8B base could grow >15% p.a. if OP reaches ¥100B. Override: growth is recovery from distorted FY2025 NI base (FX+cost anomaly), not extrapolation of elevated rates.
• Capacity expansion risk (AP02): New Kitakyushu factory +50% capacity. All 4 major robot OEMs expanding. Monitor utilization H2 FY2026.
• Thesis breaks if: Dash 35 targets revised down before FY2028; China revenue declines >20% YoY for 2 consecutive quarters; July 9 tariff reinstated at 24% AND US manufacturing not sufficiently ramped by year-end.
