Findings by question
F1Quarterly and full-year results summaries (tanshin) published in English5/5
Consolidated Financial Results for the Three Months Ended June 30, 2026 (Japanese GAAP), 23 July 2026, posted with the Japanese (both PDFs created 22 July): 10 pages against the Japanese 12, with the qualitative information on results, position and forecasts, the statements, and the notes including segment information; the Japanese extra pages are the auditor's interim review report. The full-year release (27 April 2026) is 16 pages against 14. Q2 (23 Oct 2025) and Q3 (26 Jan 2026) are in the English library likewise. Every period, same day, complete. Source document →
F2English results summary is a full translation, not an excerpt5/5
Q1 FY3/2027 tanshin, 23 Jul 2026. The English 'Consolidated Financial Results for the Three Months Ended June 30, 2026 [Japanese GAAP]' is 10 pages; the Japanese 2027年3月期第1四半期決算短信 is 12. The English has the summary pages (results, dividends, forecast, notes), 1. Qualitative Information (operating results with a narrative and sales/profit for each of the four segments, financial position, forecast explanation), 2. the balance sheet, income statement and comprehensive income statement, and 3. the notes (going concern, shareholders' equity, segment information, cash-flow note). The Japanese extra pages are the auditor's interim review report, which does not count. The FY3/2026 year-end tanshin (27 Apr 2026) is 16 English pages against 14 Japanese, with the cash-flow statement, changes in equity and the segment note. The whole tanshin, so 5. Source document →
F3Financial statements including notes available in English5/5
The latest-period English tanshin (Q1 FY3/2027, 23 Jul 2026) carries the quarterly balance sheet, income statement and comprehensive income statement, and the notes: going concern, significant changes in shareholders' equity, segment information by reportable segment with the reconciliation, and the cash-flow note (depreciation). The year-end English tanshin (27 Apr 2026, 16 pp) adds the cash-flow statement and the statement of changes in equity. Full statements and notes for the latest period, so 5. Source document →
F4Annual securities report available in English in any form0/5
The English IR Library has Financial Results/Presentation materials, Corporate Brochure and Annual Review only; the Japanese library's 有価証券報告書／半期報告書 (第66期 filed 19 June 2026) has no English counterpart under any name. The Annual Review's data section is an 11-year summary, not statements with an audit opinion.
F5Segment revenue and profit disclosed in English, consistent definitions5/5
Three reportable segments (Electronic Devices, Precision Molding Products, Housing & Living Materials) plus Others. Every English tanshin gives sales and segment profit (operating profit) per segment, in the qualitative section and in the segment note (e.g. Q1 FY3/2027: Precision Molding ¥15,305m sales, ¥2,838m profit; FY3/2026 table with depreciation, goodwill and impairment by segment; Others defined as the construction business etc.). The FY deck has the segment table and an eight-quarter segment sales/profit table; the English Segment Information page shows five years of segment sales and profit on unchanged segments; the Annual Review 2026 and the deck's 'Business Segment' page state what each segment covers (products, base and growth areas). Every period, definitions stated and constant, so 5. Source document →
F6Multi-year financial data file (Excel or CSV) downloadable in English0/5
No downloadable data file. Searched the English Financial Highlights, Financial Indicators, Cash Flow and Segment Information pages (five-year HTML charts with values), the IR Library (results, brochure, Annual Review) and the Japanese financial and library pages for .xls/.xlsx/.csv links: none. What exists instead is the HTML charts, the 11-year data section of the Annual Review (PDF) and the five-year table in the deck appendix.
F7Guidance disclosed in English with the basis explained3/5
The FY3/2026 tanshin (27 Apr 2026) gave no FY3/2027 forecast ('difficult to reasonably estimate'), stated in English. The forecast came on 23 Jul 2026 with the Q1 tanshin and an English 'Notice on Consolidated Financial Results Forecast and Dividend Forecast': net sales ¥120,000m, OP ¥16,000m, ordinary ¥16,000m, net ¥10,500m, EPS ¥130.64, dividend ¥66. The only basis given is 'in light of the recent business environment, its performance trend, and other factors'; no FX assumption, market view or segment forecast accompanies it (no deck at Q1, and the FY deck of 15 May has no outlook). The last FX premise in English is the MTP's FY2025 forecast (USD 140, EUR 165). The numbers only, so 3. Source document →

English results for the three months to 30 June 2026 posted 23 July 2026, the same period and day as the Japanese first-quarter tanshin. Source document →
S1Medium-term management plan in English with numerical targets5/5
The current plan is the revised 'Shin-Etsu Polymer Global & Growth 2029' (FY2025-FY2029), announced 7 Nov 2025. The English 'Notice Concerning to the Revision of Medium-term Management Plan' was posted the same day as the Japanese 中期経営計画更新に関するお知らせ, both 26 pages (both PDFs created 7 Nov). It carries the FY2029 targets: net sales ¥150bn, ordinary profit ¥20bn, ROE approx. 10%, payout above 50%, FX premise USD 140 / EUR 165; segment sales and OP targets (charts), overseas sales ratio over 60%, the ¥68bn capex and strategic investment plan by area, cash allocation, and ESG targets. Annual Review 2026 repeats the targets with segment FY2029 figures. Current plan, complete and same day, so 5. Source document →
S2IR presentations published in English5/5
The Japanese side holds briefings at the half year and full year only (Q1/Q3 tanshin: 'supplementary material: None'), and English matches it item for item: Presentation materials for the year ended March 2026 (22 pages, posted 15 May 2026 with the Japanese 22-page deck) and the President's Remarks and Q&A Summary (21 May, same day as the Japanese 社長挨拶および質疑応答要旨); the Q2 FY2025 deck (26 pages, same creation date as the Japanese) with its President's Address and Q&A Script. Source document →
S3English equity-story or investment-highlights page5/5
No 'why invest' or investment-highlights page on the English IR site. Annual Review 2026 (written, it says, for shareholders and investors) has a dedicated 'Three Strengths of Shin-Etsu Polymer' / 'Competitive Advantage' section (development, proposal and response capabilities), a value-creation diagram, and a market-position spread: key switches No.1 domestic share, semiconductor-related containers No.1 global share, industrial PVC cling wrap No.1 domestic share, with the segment sales mix (22% / 52% / 19%). The market positions are on the Business Overview spread (printed p.15), one per segment. Re-checked 21 Oct 2026 under the rule as written: a section in an investor document counts the same as a page, and a named market rank counts as a quantified strength. A dedicated section with quantified strengths, so 5. Source document →
S4Growth drivers identified and quantified in English5/5
Drivers are named and quantified in English. The revised MTP (7 Nov 2025) names the growth areas by segment (semiconductor-related and medical products; battery and fuel-cell parts; heat-resistant films and conductive polymers) and puts numbers on them: FY2025-29 investment of ¥22bn in semiconductor-related products, ¥5bn EV-related, ¥10bn functional materials, ¥16bn renewal and up to ¥15bn M&A; overseas sales ratio from 55% to over 60%. Annual Review 2026 adds FY2029 segment targets (Electronic Devices sales ¥36.3bn / OP ¥9.1bn from ¥25.7bn / ¥1.7bn; Precision Molding ¥72.4bn / ¥19.3bn from ¥59.7bn / ¥10.2bn; Housing & Living ¥30.5bn / ¥7.5bn), the No.1 global share in wafer containers and the ~¥21.5bn FOSB capacity build. Named drivers with numbers, so 5. Source document →
S5Results-briefing transcripts or Q&A published in English4/5
The Japanese side publishes a 社長挨拶および質疑応答要旨 for each of its two briefings a year, and English has each. FY3/2026 briefing: 'President's Remarks and Q&A Summary', 5 pp, listed 21 May 2026, the same day as the Japanese (4 pp; both PDFs re-created 28 May). Q2 FY3/2026 briefing: Japanese posted 12 Nov 2025, English 'President's Address and Q&A Script' (4 pp) posted 19 Nov 2025 (PDF created 18 Nov), seven days later. The archive runs back to FY3/2022.

S7Progress against the previous plan, including misses, explained in English5/5
The English MTP revision (7 Nov 2025) opens with 'Review of the Previous Plan': a table setting the pre-revision 'Global & Growth 2027' targets (net sales ¥150bn, ordinary profit ¥20bn, ROE just over 10%, payout ~50%) against FY2022-FY2024 actuals (¥110.6bn, ¥13.2bn, 8.0%, 44.4%), with the variance explained (prolonged semiconductor inventory adjustment pushed earnings expansion back about two years, hence the two-year extension), plus segment progress, capex delivered (¥25.4bn of ¥66bn) and a note that no M&A was made. Annual Review 2026 updates it ('Performance Against Numerical Targets and Key Challenges': FY2025 actuals against previous and revised targets, with explanations by business and for base areas, growth areas and the overseas ratio). Target against actual, explained, so 5. Source document →
G1Corporate governance report available in English3/5
No Corporate Governance Report in English; the Japanese governance page carries コーポレートガバナンスに関する報告書 (updated 26 June 2026). The English IR > Corporate Governance page gives the basic view, the five-point basic policy and the governance structure, with a Sustainability > Governance page beside it - a narrative written for the site in place of the filing. Source document →
G2Director biographies in English with tenure, expertise and independence5/5
The board is five directors (company with an Audit & Supervisory Board), all up for election in 2026. The English notice of the 66th AGM (posted 29 May 2026) profiles all five: dated career summary, significant concurrent positions, shares held, board attendance, tenure (Ono 13 years, Deto 14, Miyashita 7, Kowada new; Murata's one-year tenure in the text), reasons for nomination, and outside/independent status, with the note that Miyashita and Murata are filed as independent officers. Every director, all three elements, so 5. Source document →
G3Board skills matrix published in English5/5
The English 66th AGM notice (p.15, 'Composition of the Board of Directors after this General Meeting (tentative) and Skill Matrix') maps all five directors and four Audit & Supervisory Board members against seven areas (corporate management, global, technology and manufacturing, marketing, finance and accounting, legal and governance, human capital management), with outside/independent attributes. Annual Review 2026 (p.25) repeats it. Current matrix in English, so 5. Source document →
G4Executive remuneration structure and its performance linkage explained in English3/5
The only English description is in Sustainability Report 2025 (Executive Compensation): pay for senior management and directors 'consists of basic compensation, bonuses linked to annual performance, and stock options aimed at improving medium-term performance', set through the Nomination & Compensation Committee. No KPIs, weights or amounts in English: the AGM notice does not carry the business report, Annual Review 2026 describes only the committee, and the CG report and yuho (where the amounts are) are Japanese-only. Structure only, so 3. Source document →
G5AGM notice in English with sufficient lead time to vote4/5
Notice of Convocation of the 66th AGM, posted in English on 29 May 2026 (same day as the Japanese) for a meeting on 24 June - 26 days - 15 pages with the Reference Documents for all four proposals, including the five director candidates and the shareholder proposal with the board's reasons for opposing it. It gives the deadline (5:35 p.m., 23 June) and the methods, but for internet voting refers the reader to page 5 of the Japanese notice, 'Information About Exercising Your Voting Rights via the Internet, etc.' (Japanese only). The voting route is Japanese-only. Source document →
G6Shareholder vote results disclosed in English0/5
The English Shareholders Meeting page lists convocation notices only (56th to 66th) and the English IR News has nothing after the 29 May notice but 'Matters Concerning Controlling Shareholders'. The Japanese page carries 決議ご通知 for each meeting; no notice of resolutions and no voting results in English.
G7Cross-shareholdings in English with reduction schedule and rationale0/5
Nothing on cross-shareholdings in English. Searched the English Corporate Governance and Sustainability > Governance pages, the 66th AGM notice, Annual Review 2026 and Sustainability Report 2025 (full text) for cross-/strategic/policy shareholdings: no policy, count or amount. The policy sits in the Japanese CG report (principle 1-4) and the Japanese yuho, neither of which is in English.

All render their content; no empty lists or blank widgets. The stock price link goes to Nomura's quote site (third party). So 5. Source document →
O5Single page listing all English IR documents by date and type4/5
The English IR・Press Release page is one dated list of every English IR document (120 items, filterable by year back to 2016): tanshin, decks, Q&A scripts, AGM notices, Annual Review, Corporate Brochure and all timely disclosures. Every entry is tagged just 'IR', so it is not typed. The typed library is split across pages (Financial Results・Presentation materials, Corporate Brochure, Annual Review, Shareholders Meeting). One dated all-types list, untyped, so 4 under the review ruling. Source document →

Several years across types, so 5. Source document →
O7Named English IR contact published3/5
A dedicated English 'Inquiry for IR' form exists, but no IR page links to it: the IR top, IR FAQ and IR Policy pages link only to the site-wide Contact Us page, where 'Inquiry for IR' sits under 'Other Inquiries' below the long product list. The English tanshin names Osamu Kowada, Director, Managing Executive Officer, +81-3-5288-8404. Genuine IR route, not obvious. Source document →

Our analysis, not a company statement
Balance sheet and capital-policy indicators
A source-backed first-pass capital-efficiency, balance-sheet and governance reading, separate from the accountability score.
Cash use and returns
Shin-Etsu Polymer continues growth investment in semiconductor wafer containers and other differentiated products while targeting a payout ratio above 50%.
Capital structure
Management emphasizes financial soundness for cyclical semiconductor and automotive markets; explicit leverage and liquidity ranges are not disclosed in the selected sources.
Governance of capital decisions
The revised plan sets FY2029 sales, profit, ROE and payout goals and identifies capital turnover and margin improvement as ROE drivers.

Surplus cash, leases, maturities, project ROIC, cost of capital, committed spend and peer comparability are not fully assessed; none enters the accountability score. Figures are the company’s own reported numbers; a large cash balance is not called excess without a defensible operating reserve and investment plan. Every company with a balance-sheet reading →
