Kokusai Electric (6525.T) — Graham Screen L1-WFE

Screened: 2026-05-28 | Price at screen: JPY 7,770 (last close May 27) Thesis framing: Specialty batch-furnace deposition WFE; KKR spin from Hitachi Kokusai (2017); TSE IPO Oct 2023; trough-of-cycle margins; HBM batch furnace bull case


PRICE SNAPSHOT

Metric Value
Current price JPY 7,770 (May 27 close) / JPY 8,124 (intraday May 28)
52-week high JPY 8,279
52-week low JPY 2,607
Distance from 52W high -6.1% (essentially at 52W high)
YTD return +31.1% (JPY 5,928 Jan 5 -> JPY 7,770)
IPO price (Oct 2023) ~JPY 1,840
Return since IPO +322%
Market cap JPY 1,897B (~EUR 11.6B at 163 JPY/EUR)

Trip wire: YTD 31.1% does NOT exceed 80% threshold, so full screen applies. But note the stock is within 6% of its 52W high after a +322% rerate from IPO — this is the functional equivalent of a "peak" for Graham screening purposes.


1. COMPANY OVERVIEW

Kokusai Electric is the global leader in vertical batch thermal processing equipment for semiconductors — specifically diffusion furnaces, oxidation systems, LPCVD, and ALD. The company claims 70-80% global market share in vertical batch thermal, a product class where batch economics (processing 100-150 wafers simultaneously) are structurally advantaged over single-wafer tools for certain applications.

Key products: Batch diffusion/oxidation furnaces, ALD systems, LPCVD. Used in DRAM, HBM, NAND, logic nodes.

Corporate history: Hitachi Kokusai Electric semiconductor equipment division -> KKR LBO in 2017 -> renamed Kokusai Electric -> TSE IPO October 2023 at JPY 1,840. KKR has fully exited as of May 2026 (confirmed in news: "KKR completed exit from Kokusai Electric," May 23 2026).

Fiscal year: March 31 year-end (FY2025 = April 2024 - March 2025).


2. (a) HBM BATCH FURNACE EXPOSURE — THE BULL CASE

HBM (High Bandwidth Memory) stacks require precise thermal oxidation and nitridation at each bonding layer — vertical batch furnaces are the tool of choice due to wafer-level uniformity requirements and throughput. As HBM generations progress (HBM2E -> HBM3 -> HBM3E -> HBM4), layer count increases, multiplying the thermal processing steps per wafer stack.

Why Kokusai specifically:

Assessment of bull case vs current price: The stock has already re-rated from JPY 1,840 (IPO, Oct 2023, at ~11x trailing P/E) to JPY 7,770 (May 2026, at ~51x trailing P/E). The HBM batch furnace narrative drove this 4x re-rating. The thesis is not wrong — it is already priced in and then some. The question is not "will HBM benefit Kokusai?" (yes) but "does JPY 7,770 compensate you for the execution risk, China risk, and cycle risk?" At 51x trailing P/E the answer is no.


3. (b) CHINA REVENUE EXPOSURE

Based on company segment disclosures and analyst coverage (Nikkei, Bloomberg, Morgan Stanley Dec 2025 upgrade):

Risk: If China WFE spending softens OR US export controls expand to batch thermal equipment, Kokusai's recovery reverses sharply. At 40-50% China exposure, this is an existential revenue risk, not a marginal one.


4. (c) LIQUIDITY / FLOAT

Metric Value
Shares outstanding 233.6M
Float shares 219.8M (94.1% of SO)
KKR overhang RESOLVED — KKR fully exited May 2026
Avg daily volume (10-day) 9.15M shares
Daily turnover (% of float) 4.2% — very liquid

Assessment: The initial concern about thin float is unfounded. With 219M share float and 9M daily volume, this is a highly liquid mid-cap on the TSE. The KKR overhang that depressed the stock in late 2025 (lock-up expiry Sep 2025) is fully resolved.

FX consideration for EUR portfolio: DEGIRO does support TSE trading, but EUR 3,000 (~JPY 489,000, ~63 shares) incurs FX conversion costs, JPY settlement risk, and adds EUR/JPY volatility to an already high-beta position (beta = 2.25). This is a meaningful execution friction for a small satellite.


5. GRAHAM 7 FILTERS (shr-017 PEAK-CYCLE CHECK)

IMPORTANT shr-017 WARNING UPFRONT: Kokusai's BALANCE SHEET passes several Graham filters because the company has been deleveraging aggressively post-KKR LBO (D/E dropped from very high levels at IPO to 0.31x now). The VALUATION filters fail catastrophically. This is the classic shr-017 dynamic: screening on trailing balance sheet data during a semi capex upcycle produces false positives. 7735.T (SCREEN Holdings) is the cited peer that "already failed Graham at peak" — Kokusai is in the same position.

# Criterion Graham Threshold Kokusai Value PASS/FAIL
1 Adequate size >EUR 100M mkt cap EUR 11.6B PASS
2a Current ratio >=2.0x 2.09x PASS (marginal)
2b LT Debt < Working Capital LT Debt < WC LT Debt JPY 46.9B < WC JPY 90.2B PASS
2c D/E <1.0x 0.31x PASS
3 Earnings stability Profitable 10 consecutive years IPO 2023, only 4yr public data; all profitable FY2022-FY2025 INCOMPLETE/FAIL
4 Dividend record 20 consecutive years IPO Oct 2023, no 20yr history FAIL
5 Earnings growth >33% per 10 yrs EPS FY2022: 215.3 -> FY2025: 152.5 = -29% (declining cycle); only 4yr data FAIL
6 P/E ratio <=15x trailing 51x trailing / 40.6x forward FAIL (catastrophic)
7 Price-to-book <=1.5x or P/E*P/B<22.5 P/B = 8.65x; P/E*P/B = 548 FAIL (catastrophic)

Graham Score: 3/7 PASS (size, current ratio, D/E) — but the 3 passes are structural/balance sheet artifacts of LBO deleveraging, not evidence of a value situation. The 4 fails include both valuation metrics at extreme levels.

shr-017 Peak-Cycle Trap Check

The shr-017 rule states: "High Graham screen scores on trailing data can be cyclical traps for companies entering a downcycle."

Kokusai's cycle position:

Metric FY2022 Peak FY2024 Trough FY2025 FY2026E
Revenue (JPY B) 245.4 180.8 238.9 ~250+
Operating income (JPY B) 70.6 30.7 51.3 ~64
EPS (JPY, diluted) 215.3 93.7 152.5 191.3
Trailing P/E ~11x (IPO) N/A 51x 40.6x (fwd)

Revenue is at 97.4% of prior cycle peak. The recovery is 90% complete. This is NOT a trough entry — it is close to cycle peak entry. And unlike FY2022 when the stock was priced at 11x trailing P/E (Graham-ish), it is now priced at 51x trailing P/E on essentially the same revenue base. This is definitionally the shr-017 trap.

Capex is also surging aggressively: FY2022 JPY 3.3B -> FY2025 JPY 27.7B (+8x in 3 years). This is both a signal of expansion confidence AND a FCF depressant — FCF dropped from JPY 70.3B (FY2022) to JPY 10.8B (FY2025) despite higher revenue, entirely due to capex.


6. GRAHAM INTRINSIC VALUE SENSITIVITY TABLE (shr-012 / shr-003)

Trailing EPS: JPY 128.21 (note: yfinance trailing EPS; company reports diluted EPS JPY 152.5 for FY2025 — using FY2025 reported) Forward EPS (consensus): JPY 191.26

Using FY2025 diluted EPS = JPY 152.5 (trailing) and forward EPS JPY 191.3:

Growth (g) IV (trailing EPS 152.5) MOS vs JPY 7,770 IV (fwd EPS 191.3) MOS vs JPY 7,770
g = 0% JPY 1,296 -83% JPY 1,626 -79%
g = 3% JPY 2,208 -72% JPY 2,773 -64%
g = 5% JPY 2,818 -64% JPY 3,538 -54%
g = 7.5% JPY 3,581 -54% JPY 4,495 -42%
g = 10% JPY 4,345 -44% JPY 5,451 -30%
g = 15% JPY 5,871 -24% JPY 7,364 -5%
g = 20% JPY 7,398 -5% JPY 9,278 +19%

Break-even growth rate:

shr-003 implied growth gap:

Assessment: Even under the most optimistic forward scenario (g=20% perpetual), the stock is barely at fair value. Graham's formula was designed for mature, slow-growth companies where 10-15% is a high growth assumption. Requiring 16-26% perpetual growth to justify current price puts this squarely in growth stock territory — and growth stock that must sustain WFE cycle-peak economics indefinitely.


7. ADDITIONAL METRICS

Metric Value Notes
EV/EBITDA 33.7x Expensive for cyclical
EV/Revenue 8.0x High for equipment maker
Dividend yield 0.62% JPY 48/sh; trivial
Payout ratio 28.8% Conservative but yield is irrelevant
FCF yield 0.57% Minimal due to capex surge
ROE 14.5% Solid but not exceptional
Beta 2.25 Very high; 2x market volatility
Gross margin 42.6% Strong for WFE; structural moat
Operating margin 21.5% Below FY2022 peak of 28.8%
Current ratio 2.09x Passes Graham barely
D/E 0.31x Post-LBO deleveraging complete

8. ANALYST CONSENSUS (shr-020 RED FLAG CHECK)

Metric Value
N analysts 10
Recommendation Buy (mean 1.6/5)
Mean price target JPY 7,549
High PT JPY 10,000
Low PT JPY 3,900
Current price vs mean PT -2.8% BELOW mean PT (price already above analyst consensus!)

Morgan Stanley upgraded Dec 2025, citing AI-driven WFE recovery as "firmly underway." The upgrade is already reflected in the stock price — current price trades AT the analyst consensus mean. The stock is not "underfollowed" at 10 analysts; the WFE/HBM thesis is fully discovered.


9. SHORT INTEREST / INSIDER ACTIVITY


10. shr-020 RED FLAG STATUS (Pre-buy check)

This check applies if the stock were ever to reach a Graham-attractive price. For current price, this section confirms the verdict.

Category Status Detail
Price vs 52W high RED -6.1% from 52W high — near peak
YTD momentum RED +31.1% YTD — momentum buyer territory
Valuation (trailing P/E) RED 51x vs Graham 15x threshold
Valuation (P/B) RED 8.65x vs Graham 1.5x threshold
Graham IV break-even RED 16-26% perpetual growth needed
Analyst mean PT RED Price already above consensus mean PT
China revenue risk RED 40-50% China, export control escalation risk
Cycle position RED Revenue at 97% of prior peak, P/E at 4x IPO level
EPS trend AMBER Recovery underway but not back to peak; FY2026 looks ok
Balance sheet GREEN D/E 0.31x, current ratio 2.09x, net debt minimal
FCF trend RED FCF decimated by capex surge (JPY 70.3B -> JPY 10.8B)
Float/liquidity GREEN 219M shares, 9M daily volume, KKR overhang cleared

Red flag count: 8 RED, 1 AMBER, 2 GREEN — this is not an entry scenario at any level.


11. PORTFOLIO OVERLAP CHECK

User instruction: avoid duplicating NVDA/AVGO/TSM/ASML/AMAT/LRCX/KLAC.

Kokusai Electric is NOT a direct duplicate of these names — it is a Japanese pure-play on batch thermal equipment, not covered by major ETF WFE baskets at high weight. However, the economic exposure is correlated with ASML (litho), AMAT (CVD/ALD), and LRCX (etch/ALD) — all benefit from the same HBM/AI capex cycle. Adding Kokusai would ADD WFE beta to the portfolio, not diversify it.

Current portfolio (AGN.AS, RI.PA, AIG, AKE.PA) has zero semiconductor exposure. Adding a high-beta (2.25) WFE play at cycle peak and near-52W high would be a directional bet on the AI capex cycle continuing, not a Graham value add.


VERDICT

GRAHAM SCORE: 3/7 (FAIL)

Kokusai Electric fails 4 of 7 Graham defensive filters on the metrics that matter most — valuation (P/E 51x vs threshold 15x, P/B 8.65x vs threshold 1.5x), earnings history (IPO 2023, only 4 fiscal years), and dividend record (no 20-year history possible). The 3 passes are balance sheet metrics that reflect post-LBO deleveraging, not a value situation.

shr-017 PEAK-CYCLE TRAP: CONFIRMED

This is a textbook shr-017 scenario. The financial statements look reasonable (profitable, delevered, recovering margins), but:

  1. Revenue is at 97% of prior cycle peak
  2. The stock has re-rated 4x from IPO while EPS has barely moved (IPO: 11x trailing P/E; now: 51x)
  3. The HBM/batch furnace thesis is fully discovered (10 analysts, Morgan Stanley upgraded Dec 2025)
  4. Price already exceeds analyst mean price target
  5. Even at the most optimistic forward g=20% scenario, the stock is barely at fair value

WATCHLIST PRICE FOR GENUINE VALUE ENTRY

Using forward EPS JPY 191.3 with Graham formula and requiring 20% margin of safety:

Growth assumption IV 20% MOS entry 33% MOS entry
g = 5% JPY 3,538 JPY 2,831 JPY 2,371
g = 7.5% JPY 4,495 JPY 3,596 JPY 3,011
g = 10% JPY 5,451 JPY 4,361 JPY 3,652

A realistic WFE company with genuine batch thermal moat could justify g=7.5-10% long-term if the HBM thesis proves durable beyond the current cycle. Watchlist trigger: JPY 3,500-4,000 (requires -55% to -50% drawdown from current price).

At JPY 3,500-4,000, Kokusai would be priced at approximately:

WHY NOT BUY NOW EVEN AS A GROWTH STOCK

Per shr-004 (Growth Stock Addendum), a stock failing all Graham filters can still pass if implied growth (from current P/E) <= achievable growth. Here:


VERDICT LINE: RED — Massively overvalued vs Graham framework (P/E 51x, P/B 8.65x, IV break-even requires 16-26%/yr perpetual growth). Classic shr-017 peak-cycle WFE trap: stock re-rated 4x from IPO on HBM narrative that is already fully priced. Revenue at 97% of prior cycle peak, price already above analyst consensus mean target. WATCHLIST at JPY 3,500-4,000 (~50% drawdown) for a genuine value entry at g=7.5-10% forward IV with 20% MOS.
