Long-Term Value Research on Ibiden
Ibiden is a global leader in high-end IC package substrates (ABF/FC-BGA), with its electronics business contributing about 59% of FY2025 total sales of JPY 416.2 billion, core customers including Intel, AMD, and NVIDIA, and a mature ceramics/DPF business alongside a heavy AI/HPC-driven expansion cycle of roughly JPY 500 billion over FY2026-28, backed by a 57.3% equity ratio and net cash of about JPY 100.4 billion. The core thesis is that Ibiden owns valuable process know-how, yield capability, customer qualifications, and an early position in AI/HPC substrates, but its capital intensity, customer concentration, and mixed business profile make the current valuation demanding. Research rating Watch: a strong company worth studying, but not a price that offers enough margin of safety today.

Long-Term Value Analysis of AGC Inc.
AGC is a century-old Japanese materials group that began in glass and now spans architectural glass, automotive glass, electronic materials, chemicals, and life-science CDMO, with 2025 revenue of roughly JPY 2.06 trillion. The core thesis is that AGC owns several high-quality niche franchises, but group-level ROE, ROCE, and free-cash-flow durability have not yet converted those advantages into consistently high shareholder returns. Rating Watch: a credible harvest-period setup after heavy capex, but the current price does not offer a clear margin of safety.

Tokyo Ohka Kogyo TOK (4186.TSE) Buffett Framework Deep-Dive Research
Tokyo Ohka Kogyo (TOK) is a key global supplier of semiconductor photoresists and high-purity chemicals, serving advanced-node foundries including TSMC. FY2025 revenue and profit attributable to owners reached record highs, the balance sheet remained in a net cash position, and the equity ratio was close to 68%, but free cash flow is still well below accounting profit during a heavy capex cycle. Research rating Watch: a high-quality semiconductor materials compounder, yet at roughly ¥9,700 the stock is already near the upper end of an optimistic valuation range and lacks a sufficient margin of safety.

HOYA Corporation (7741.TSE) Buffett Framework Deep-Dive Research
HOYA is a Japanese optical precision materials platform with two engines: Life Care, covering eyeglass lenses, contact lenses, endoscopes, and intraocular lenses, contributes 62% of revenue, while Information Technology, covering semiconductor EUV mask blanks and HDD glass substrates, contributes 38% but carries exceptionally high margins of 54%. FY2026 revenue was JPY 947.7 billion, net profit was JPY 253.1 billion, net cash was JPY 531.9 billion, and financial resilience is very strong. Research rating Watch: at the current share price of about JPY 25,835, the stock trades at roughly 38x conservative Owner Earnings, sits in the optimistic valuation range, lacks a sufficient margin of safety, and has an ideal buy range of JPY 16,000 to JPY 20,000.

Peric Special Gases (688146.SHG) Buffett Framework Deep-Dive Research
Peric Special Gases is China's leading electronic specialty gases supplier, focused on chipmaking-critical gases such as nitrogen trifluoride and tungsten hexafluoride, ranking No. 1 in China and No. 9 globally by integrated-circuit electronic specialty gas sales revenue in 2024. The core thesis is that 2025 revenue reached 2.26 billion yuan, operating cash flow remained healthy, net cash was about 2.46 billion yuan, and the balance sheet was solid, but ROE has fallen from 22% to 6%, free cash flow remains under pressure, and the current PE TTM of about 370x and PB of about 22.75x are far detached from fundamental support. Rating Avoid: a capable business whose stock price has already consumed too much of the optimistic long-term story upfront.

Shin-Etsu Chemical (4063.TSE) Buffett Framework Deep-Dive
Shin-Etsu Chemical is one of Japan's largest diversified chemical groups, anchored by world-leading semiconductor silicon wafers and lithography-related materials, with electronic materials contributing 54% of operating profit, alongside one of the world's largest PVC platforms and a silicone business. FY2026 revenue was JPY 2.57 trillion, operating margin was 24.7%, and net cash exceeded JPY 1.42 trillion, giving the company an exceptionally strong balance sheet. Research rating Watch: a high-quality compounder, but the current share price of about JPY 6,863 implies roughly 27x trailing PE and leaves insufficient margin of safety.

FormFactor (FORM.US) Buffett Framework Deep-Dive Research
FormFactor is a leading global supplier of semiconductor wafer-test probe cards, serving top fabs such as Intel, Samsung, SK hynix, TSMC, and Micron, with technical and relationship barriers built through early customer engagement and global delivery capability. The company benefits from strong HBM/AI demand and posted record revenue in Q1 2026, but the current share price of about $124.25 implies roughly 62 times target non-GAAP EPS, far above a conservative intrinsic value range and leaving almost no margin of safety. Research rating Watch: a high-quality niche semiconductor test leader, but the price has moved far ahead of verifiable owner earnings.

Air Liquide (AI.PA) Buffett Framework Deep-Dive Research
Air Liquide is one of the global leaders in industrial and medical gases, serving 4.3 million customers and patients across 59 countries, with oxygen, nitrogen, hydrogen, electronics specialty gases, and medical gases deeply embedded in customer production processes. In 2025, revenue reached EUR 26.94 billion, operating cash flow was EUR 6.52 billion, recurring ROCE stayed solid at 11.2%, and net debt continued to fall over five years to EUR 8.42 billion. Rating Watch: a classic infrastructure, consumables, and long-term service contract compounder with strong contract stickiness and a deep moat, yet the current share price of about EUR 183 implies roughly 30x P/E and already reflects much of its quality, leaving insufficient margin of safety.

SUMCO (3436.TSE) Deep-Dive Research Under the Buffett Framework
SUMCO is the world's second-largest semiconductor silicon wafer manufacturer, focused on high-precision 300mm wafers, with roughly 30% global share and more than 50% share in wafers for leading-edge logic chips, deeply embedded in the TSMC, Samsung, and Kioxia supply chains. FY2025 revenue was ¥409.7bn, while depreciation pressure and the cycle trough drove a net loss attributable to owners of ¥11.8bn, with Q1 FY2026 still loss-making and net debt at roughly ¥263.9bn as the heavy-asset capacity expansion cycle remains unfinished. Research rating Watch: the current share price of roughly ¥3,499 is already near the upper end of the optimistic valuation range, leaving insufficient margin of safety and making the stock better suited for a watchlist pending a price pullback.

Hexagon AB (HEXA-B.ST) Zen Horizon Deep-Dive Research Report
Hexagon AB is Sweden's leader in industrial metrology, digital reality capture, and autonomous solutions, built through 150+ acquisitions over 28 years. Its largest-ever restructuring, completed on 2026-05-28, spun out the software SaaS business Octave as an independent listing and left four core businesses: precision measurement, geospatial information, autonomy, and robotics. Research rating Watch: Q1 2026 showed resilient growth and margin quality, but Forward P/E of 22x, industrial-cycle risk, and dual-class governance make SEK 75-80 a more attractive entry range.

Mitsubishi Heavy Industries (7011.TSE) Zen Horizon Deep-Dive Report
Mitsubishi Heavy Industries is Japan's largest heavy-industrial group, founded in 1884, with four operating pillars across Energy Systems, Aircraft, Defense & Space, Plant & Infrastructure, and Logistics, Thermal & Drive Systems. FY2025 revenue reached ¥4,974B (+14.1%), net income ¥332B (+35.3%), orders ¥7,654B (+20%), and backlog a record ¥13,238B, while the AU$10B Mogami frigate contract with Australia marked Japan's largest postwar weapons export. Report rating Watch: Japan's defense expansion, the second GTCC upcycle driven by AI data centers, and Japan's industrial re-rating are powerful themes, but the current valuation already prices in much of the upside.

Kazatomprom (KAP.IL) Zen Horizon Deep-Dive Report
Kazatomprom is Kazakhstan's national atomic company and the world's largest uranium producer, supplying about 22% of global primary output while sitting at the low end of the cost curve through its ISL mining model. The core thesis is a rare combination of scale, cost leadership, and high dividends, offset by sulfuric acid inflation, state-control discounts, and China-Russia-linked geopolitical risk. Rating Watch: a durable uranium leader, but the current price offers a roughly balanced risk-reward rather than a clear margin of safety.

Nintendo (7974.T / NTDOY) Zen Horizon Framework Deep Research
Nintendo is one of the world's strongest gaming IP empires, founded in Kyoto in 1889 as a hanafuda card maker and later becoming one of the three global console pillars alongside Sony PlayStation and Microsoft Xbox after the NES became a worldwide hit in 1985. Its core business is Switch 2 hardware plus first-party software, which together account for 85% of revenue, alongside smartphone games, Switch Online subscriptions, Nintendo films, USJ theme parks, and IP licensing. Research rating Buy: a durable IP moat, cash-generative platform economics, and a conservative FY2027 guide leave meaningful upside from a depressed valuation.

MediaTek (2454.TW) Zen Horizon Framework Deep-Dive Research
MediaTek is the world's second-largest fabless chip designer after Qualcomm and ranked among the global top ten semiconductor companies by 2025 revenue, with a business mix spanning mobile chips, smart edge platforms, and an emerging AI ASIC franchise. The central investment debate is whether the 2026 AI ASIC revenue target, doubled from USD 1 billion to USD 2 billion, can justify a valuation that already prices in a major 2027-2028 breakout despite FY2025 net income declining 1.0%. Research rating Watch: a strong strategic option in AI ASICs, but current valuation leaves little margin of safety.

iFLYTEK (002230.SHE) Zen Horizon Research Report
iFLYTEK is China's leading integrated AI voice, foundation-model, education, government, healthcare, and automotive player, and the only listed pure AI full-stack company in the A-share market. FY2025 revenue reached RMB 27.105 billion (+16.12%), net profit attributable to shareholders was RMB 839 million (+49.85%), non-GAAP recurring net profit was RMB 264 million (+40.47%), overseas revenue surged 275%, and R&D spending reached RMB 5.364 billion, or 19.79% of revenue; Q1 2026 revenue was RMB 5.274 billion (+13.23%), but the recurring loss widened to RMB -430 million. Rating Watch: Spark V4.0 to X1 to X2, fully domestic compute training, strong overseas momentum, two U.S. Entity List events in 2019 and 2023, and founder Qingfeng Liu's 20.82% aggregate control make this a high-quality but fully priced AI theme stock.
35/100
Samsung SDI (006400.KO) Zen Horizon Research Report
Samsung SDI is South Korea's largest integrated battery company and one of the world's top five lithium battery makers by cumulative installations, with Energy Solutions contributing about 93% of revenue and Electronic Materials about 7%. FY2025 revenue was KRW 13.27 trillion (-21%), with an operating loss of KRW 1.72 trillion and a net loss of KRW 64.9 billion; Q1 2026 revenue rebounded to KRW 3.58 trillion (+12.6%), operating loss narrowed by 64.2%, and net income turned positive at KRW 56.1 billion, but its global EV battery share fell out of the top 10. Research rating Watch: the turnaround signals are visible, but valuation already prices in recovery while dilution, JV delays, and market-share erosion remain unresolved.

Rocket Lab (RKLB) Zen Horizon Research Report
Rocket Lab is the second-largest listed commercial space player after SpaceX, with a vertically integrated stack spanning rocket design, launch, satellites, and payloads. The core thesis rests on Electron small launchers, about 30% of launch services with 21 launches and a 100% success rate in FY2025, plus Space Systems at about 70%, including the SDA USD 816 million 18-satellite contract and the USD 275 million Geost acquisition that moves the company into military payloads. Research rating Watch: FY2025 revenue reached USD 602 million, backlog rose to USD 1.85 billion, and Q1 2026 revenue reached USD 200 million, but the delayed Neutron medium-lift rocket, now pushed to Q4 2026, remains the key valuation turning point.
47/100
Cameco (CCJ.US / CCO.TO) Zen Horizon Research Report
Cameco is the largest uranium producer in the Western world, with roughly 18% global share, and owns a strategic 49% stake in Westinghouse, the leading U.S. nuclear equipment company. The core thesis is a full nuclear-fuel-cycle position spanning upstream uranium mining, midstream conversion, and downstream reactor OEM exposure, supported by FY2024 revenue of CAD 3.14 billion, adjusted EBITDA of CAD 1.395 billion, and Q1 2026 net income growth of 87%. Report rating Watch: a high-quality nuclear-cycle asset, but the current price already embeds optimistic assumptions for uranium, Westinghouse, and SMR optionality.

Subsea 7 (SUBC.OL) Zen Horizon Research Report
Subsea 7 is one of the two global leaders in subsea oil and gas engineering and services, designing, installing, connecting, and maintaining full subsea infrastructure systems for deepwater oil and gas fields and offshore wind farms. The core thesis is a structurally stronger margin profile, USD 13.5 billion of backlog at the end of Q1 2026, and a pending 50/50 merger with Saipem to form Saipem7, expected to close in H2 2026. Report rating Watch: a high-quality cyclical compounder with a merger catalyst, but the current NOK 332.6 price already embeds optimistic execution and leaves limited downside protection.
U.S. Market Daily Close｜2026-06-08
An oversold bounce in chip stocks held up the Nasdaq and S&P 500, but the Dow finished lower and breadth was uneven, leaving the market in sector-rotation mode ahead of CPI. The bounce was concentrated in beaten-down AI and semiconductor names rather than a broad-based advance, with rates and oil still applying pressure. Rating Watch: a single-day chip rebound looks more like a technical repair after last Friday's selloff than a fresh trend confirmation, so wait for breadth, rates, and oil to align.
