Date: 2026-05-31

Stocks updated: 8698.T (Monex Group), 9509.T (Hokkaido Electric Power), 6758.T (Sony Group)

Methodology: T-Glass Supply Chain Bottleneck Analysis + ReACT verification

Executive Summary

Three stocks with oldest data_date (2026-04-14) were evolved in this round. The most significant development is 9509.T (Hokkaido Electric Power) being upgraded to MEDIUM-HIGH conviction after its monitoring trigger was confirmed: Japan's Nuclear Regulation Authority approved Tomari Unit 3's safety review on July 30, 2025 — a 12-year process that has now definitively cleared. For 6758.T (Sony), the accounting artifact thesis was fully confirmed: ROE has normalized to 14.3% and FCF to +¥1.49T, with the image sensor business hitting all-time highs. For 8698.T (Monex Group), the company returned to profitability but the crypto tax reform timeline is a new concern.

1. Monex Group (8698.T) — HOLD

Thesis Status: HOLD

Prior conviction: MEDIUM → Current conviction: MEDIUM (unchanged)

Data staleness fixed: 2026-04-14 → 2026-05-31

What Changed

Positive:

• FY2026 NI confirmed at ¥10.9B — swing from ¥5.1B loss prior year (first profitability in 2 years)
• CNCK (Nasdaq-listed Coincheck Group) at $2.25 — above the $1.50 monitoring trigger floor, no trim signal
• Japan crypto tax reform (55% → 20%) formally enacted in December 2025 reform outline
• 3iQ integration under Coincheck completed — institutional crypto AUM capability added
• Dividend ¥30.80/share = 4.8% yield (highest in crypto group)

Negative:

• Japan crypto tax reform implementation may be delayed to 2028 per industry sources — removes near-term catalyst
• Coincheck Q3 FY2026 trading volume fell 25% YoY (¥87.7B vs ¥117.4B) — volatile
• CNCK at $2.25 remains far below listing price (~$6); impairment risk to parent if sustained
• Stock trading near 52-week low ¥640 despite fundamental improvement — sentiment overhang

Key Metrics (as of 2026-05-31)

Thesis Breaks If

• CNCK drops below $1.50 (monitoring trigger) → TRIM to 3%
• Japan crypto tax reform delayed to 2029+ → core thesis catalyst lost
• BTC drops >40% and Coincheck reports quarterly loss → EXIT

Inversion

The bull thesis requires crypto tax reform AND CNCK recovery above $4. Both are now on uncertain timelines. The bear case (sustained CNCK decline + tax delay + BTC bear market) would reduce Monex to a mid-tier online broker with no crypto premium, implying downside to ¥300-350 (book value).

Anti-Pattern Check

• Peak Earnings Trap: CLEAR — FY2026 is first profit year after loss; not at cyclical peak
• Concept Stock: CLEAR — crypto ~60-70% of actual revenue
• Capacity Hangover: N/A

Valuation Guardrail Check

• No guardrails triggered for 8698.T

2. Hokkaido Electric Power (9509.T) — UPGRADED ↑

Thesis Status: UPGRADED

Prior conviction: MEDIUM → Current conviction: MEDIUM-HIGH

Monitoring trigger: ✅ CONFIRMED — Tomari Unit 3 NRA safety review approved July 30, 2025

What Changed

Major positive catalyst confirmed:

• Tomari Unit 3 (912MW): Japan's NRA approved safety review July 30, 2025 — after 12 years of review under post-Fukushima standards. Restart target confirmed for "as soon as possible in 2027." Seawall (under construction since March 2024) expected complete early 2027.
• SoftBank Tomakomai DC power supply CONFIRMED: Press releases confirm Hokkaido Electric Power is listed alongside SB Power as power supplier for the 300MW+ Tomakomai AI DC. Phase 1 (50MW) groundbreaking April 2025.
• Rapidus IIM-1 fab progressing: 2nm PDK released to early-access customers February 2026; mass production target 2H FY2027. Chitose, Hokkaido = HEPCO territory.
• Stock +32.93% in 52 weeks — monitoring trigger partially priced in, but PBR still only 0.46x

Negative:

• Q4 FY2026 was a loss (-¥4,824M); FY2026 NI ¥44B but forward PE 6.74x implies forward NI ~¥28B — earnings to normalize lower before nuclear restart
• FY2026 revenue declined -5.1% YoY, OP -4.2% — pre-restart earnings pressure
• Local consent lawsuit for Tomari (filed 2011) still pending

Supply Chain Added (0 → 3 entries)

Key Metrics (as of 2026-05-31)

Thesis Breaks If

• Local consent lawsuit leads to Tomari Unit 3 injunction → restart blocked, EXIT
• D/E exceeds 5.0x (currently 4.17x) without earnings recovery → EXIT
• Rapidus project canceled → removes major future power customer

Inversion

Bull case requires Tomari Unit 3 restart in 2027 + DC power demand ramp. Bear case: restart delayed to 2028+ AND DC build-out slower than expected → HEPCO remains an over-leveraged utility with capped upside.

Anti-Pattern Check

• Peak Earnings Trap: CLEAR — Revenue declined -5.1%, Q4 was a loss. NOT at peak.
• Concept Stock: CLEAR — direct power utility, 100% real utility revenue
• PB percentile: CLEAR — PBR 0.46x is historically very cheap for a Japanese utility

Risk Flags

• Guardrail: EV/debt validation — D/E 4.17x means EV significantly exceeds market cap. *Override: standard for Japanese regulated utilities; all major Japanese electric utilities carry similar leverage structures.*

3. Sony Group (6758.T) — HOLD (Thesis Confirmed)

Thesis Status: HOLD (Original Thesis Confirmed)

Prior conviction: MEDIUM → Current conviction: MEDIUM (unchanged)

Original thesis (April 14): Negative ROE/FCF were accounting artifacts from SFGI spin-off

Confirmed: ✅ FY2026 actuals show ROE 14.3%, FCF +¥1.49T

What Changed

Bull case confirmed:

• ROE 14.3% (vs prior -6.4% accounting artifact) — thesis validated
• FCF +¥1.49T (vs prior -¥344B accounting artifact) — thesis validated
• I&SS (image sensors) all-time high: Revenue ¥2,151.5B (+20% YoY), OP ¥357.3B (+37% YoY) — record
• TSMC JV MOU signed May 2026 — Sony and TSMC forming JV for next-gen AI/automotive sensors at Sony Kumamoto fab. Sony as majority shareholder. Targets physical AI: vehicles, robotics.
• ¥500B share buyback confirmed
• FY2027 guidance: revenue ¥12.3T, OP ¥1.6T (+10.5%), NI ¥1.16T (+12.5%)

New risks identified:

• I&SS at ALL-TIME HIGH profits — peak earnings monitoring required (AP01 flag)
• PS5 Q4 FY2025 down 46% YoY (1.5M units) — gaming hardware cycle declining
• Sony Honda Mobility Afeela EV discontinued — removes one autonomous vehicle revenue path
• TSMC JV non-binding MOU — capex commitment unknown; could add burden

Key Metrics (as of 2026-05-31)

Supply Chain Update

• TSMC JV entry upgraded from 'fabrication partner' to new strategic status: May 2026 MOU for next-gen sensor development and manufacturing at Sony Kumamoto fab. JV targets AI/automotive — confirms Sony's structural pivot from smartphone-dependent sensor maker to AI-era sensor company.
• Apple relationship confirmed — I&SS record results driven by "major customer" higher ASPs
• Tesla / AV OEMs: Afeela discontinued, but TSMC JV specifically targets physical AI applications (vehicles, robotics) — potentially replacing Afeela with a broader sensor strategy

Thesis Breaks If

• I&SS OP declines >10% YoY in FY2027 (would suggest cyclical peak, not structural growth)
• TSMC JV requires >¥500B capex commitment without clear revenue timeline
• PS5 successor delayed AND gaming segment revenue declines >15% YoY

Inversion

I&SS at record highs raises peak earnings concern. FY2027 guidance (OP ¥400B) shows continued growth, and TSMC JV signals structural automotive demand. If the automotive/AI sensor transition is slower than expected AND smartphone demand softens, I&SS could see a 20-30% OP decline — reducing the investment case significantly.

Anti-Pattern Check

• Peak Earnings Trap: ⚠️ FLAG — I&SS at ALL-TIME HIGH OP ¥357.3B. Override: FY2027 guidance ¥400B shows continued growth; smartphone share declining from 66% → ~45% of revenue replaced by higher-value automotive/AI applications. TSMC JV confirms structural not cyclical. Monitor annually.
• Concept Stock: CLEAR — I&SS is 17% of total revenue (¥2,151B / ¥12,479B). Legitimate.
• PB percentile: Not triggered — Sony is diversified consumer/tech, not a traditional cyclical.

Risk Flags

• AP01 Peak Earnings Warning — I&SS: I&SS operating income at historical all-time high. Overridden based on FY2027 guidance and structural automotive demand pivot, but flagged for annual monitoring.
• Guardrail: FCF growth >15%: FY2026 FCF +¥1.49T vs FY2025 -¥344B is >15% "growth". Override: FY2025 FCF was negative due to SFGI spin-off accounting, not operations. FY2026 ¥1.49T is the normalized baseline.
