確認メモ（原文・英語）Summary of Financial Statements for Q1 of the year ending March 2027, in English, 7 August 2026 - 13 pages with the segment note. No cash flow statement, which the Japanese Q1 tanshin also omits.
確認メモ（原文・英語）Read page for page against the Japanese. Q1 FY2026 (Aug 7, 2026): English 12 pages against the Japanese 12, with the summary, qualitative overview, forecast notes, quarterly balance sheet, income and comprehensive income statements and notes including '(Notes on segment information, etc.)' on p.11. FY2025 tanshin (May 14, 2026): English 24 pages against Japanese 22, with the full attachment table of contents: operating results by sub-segment with major contributors, financial position, cash flows, dividend policy, accounting standards, balance sheets, income, comprehensive income, changes in net assets, cash flows, and notes (going concern, changes in presentation, additional information, segment information, per share, subsequent events), plus the non-consolidated summary. The whole tanshin.
確認メモ（原文・英語）The latest period (Q1 FY2026, English tanshin of 7 Aug 2026) carries the quarterly consolidated balance sheet, income and comprehensive income statements and notes including segment information; no cash-flow statement, which the Japanese Q1 tanshin also omits. The FY2025 English tanshin carries all four statements with full notes. Full statements and notes for the latest period.
確認メモ（原文・英語）The English IR Library runs to earnings reports, briefing presentations, the integrated report, shareholders' meeting materials and a sustainability data book. No securities report, and the company reports none to TSE.
確認メモ（原文・英語）Sales and operating profit by segment every period: Chemicals (with sub-segments Polymer Additives, Semiconductor Materials, Environmental Materials), Food Products, Life Science, Others, in both the tanshin qualitative section and the segment note. The FY2025 English segment note states how reportable segments are determined, lists the major products of each, and says segment profit is operating profit; the April 2025 reclassification (Electronic Materials renamed Semiconductor Materials, electronics-related materials moved to Environmental Materials) is stated with the prior year restated. The decks repeat by-segment results and forecasts. Definitions stated and held constant.
確認メモ（原文・英語）No spreadsheet. The English 'Consolidated Financial Information' page (/en/ir/finence/) embeds Stockweather data2web iframes (Full year PL/BS/CF, Quarter, overseas sales, sales by segment) showing five years as HTML tables and charts; rendered, the frames have no CSV/Excel download. The English IR library, earnings-report and presentation pages link only PDFs and a zip of the latest PDFs (260918_ADEKA-IRe.zip). The supplemental materials are 4-page PDFs.
確認メモ（原文・英語）The FY2025 English tanshin gives the FY2026 forecast (net sales 453.0bn, OP 46.8bn, ordinary 46.6bn, net 28.8bn yen) with a market view (moderate global growth, AI/data-centre driven semiconductor expansion, Middle East and raw-material risk, stated as not factored in), FX assumptions and sensitivities (USD 153, EUR 178; about -0.11bn / -0.06bn OP per yen), and an outlook by segment with drivers. The English 'Notice Regarding Revisions to Earnings Forecasts and Dividend Forecasts' (7 Aug 2026) raises H1 and full-year figures (FY to 462.0bn / OP 50.0bn) and explains why (strong semiconductor, automotive, consumer electronics and infrastructure demand in Chemicals). The Q1 deck has forecasts by segment and revision bridges.
確認メモ（原文・英語）Mid-term plan ADX 2026 (FY2024-FY2026, the current and final year) in English: the 'Mid-Term Management Plan ADX 2026' deck is 42 pages, as is the Japanese one, with FY2026 targets: OP 53bn yen on sales 500bn, ROE 11.0%, ROIC 10.5%, eco-friendly product sales 115bn, GHG 199kt, women managers 6%+, capex 75bn over three years, payout 40%+, plus sales and OP targets by segment and sub-segment and FX assumptions (138/$, 149/EUR). The targets were in English on the announcement day (notice of 1 Apr 2024); the English deck's PDF dates (created 14 Jun 2024) are about two weeks after the Japanese (29 May 2024). The English strategy page restates the targets, and the FY2025 deck reports progress against them.
確認メモ（原文・英語）Briefing materials in English for every period, with the supplemental materials, and an English briefing archive back to FY2023. The Japanese side publishes no transcript or Q&A (video and decks only). The English decks arrive 3-4 weeks after the Japanese (Q1 FY2026 18 Sep against 25 Aug; FY2025 23 Jun against 27 May), which R1 scores; the supplements are same-day. (Reason corrected 14 Oct 2026; an earlier version said everything was same-day.)
確認メモ（原文・英語）A dedicated English 'Learn about ADEKA IN 3 MINUTES' page in the IR menu (/en/ir/stock/glance/), an at-a-glance for investors with quantified strengths: sales 416.5bn yen and OP 41.6bn (10.0%) for FY2025, overseas sales ratio 54.4%, over 50% global share in high-k materials for leading-edge memory, 100% adoption of its lubricant additive in domestic cars, No.2 global share in polymer additives, 20 countries, and the ADX 2026 targets.
確認メモ（原文・英語）Named drivers with numbers. The ADX 2026 deck sets FY2026 sales and OP targets by sub-segment against FY2023 (e.g. Electronics and IT materials 390 to 626 (100m yen), OP 97 to 153), names the semiconductor programmes (high-k ALD materials for DRAM, logic wiring materials, photoacid generators for advanced resists) with capex (about 12bn plus a ~10bn new Kuki research building) and new plants (Taiwan ALD, Chiba PAG, Fuji high-purity hydrogen peroxide). The integrated report's 'ADEKA in figures' and the glance page give market shares (high-k >50% global). The FY2025 deck tracks FY2024/FY2025 results against the FY2026 target.
確認メモ（原文・英語）No transcript or Q&A in English: the English 'Materials on Briefing Session' page carries, for each briefing, the video (svss.tv) and the deck, tanshin, supplement and notices as chapter PDFs. The Japanese side publishes none either: its 説明会資料 page has the same video archive and decks, business-briefing decks with YouTube videos, and retail-investor seminar decks (Logmi Sep 2025, Nomura IR Jan 2026, Nikkei CNBC Aug 2025), with no 質疑応答 or transcript anywhere on the page or in the IR news.
確認メモ（原文・英語）ADEKA Report 2025 in English, 16.4MB, with a Sustainability Data Book alongside - but it states 'Period Covered by This Report: Fiscal 2024 (April 1, 2024 to March 31, 2025)'. One edition behind as at 1 October 2026.
確認メモ（原文・英語）The ADX 2026 deck opens with 'Review of the previous Mid-Term Management Plan ADX 2023': a table of each target, original (Apr 2021) and revised (Aug 2022), against the FY2023 actual with a verdict: OP 35bn (revised 42bn) vs 35.4bn 'Unachieved', ROE 9% vs 8.4% 'Unachieved', capex 50bn vs 55.7bn 'Achievement', payout 30%+ vs 40.0% 'Achievement'; strategic and eco-friendly product sales plan vs result (1,531/1,522; 444/521). The explanation is thin: a chart annotated with external events (COVID, Ukraine, inflation, inventory build-up) and a line on new products falling short, not a reasoned variance analysis per target. Reconciliation present, explanation partial.
確認メモ（原文・英語）The Corporate Governance Report filed with TSE, in English, 39 pages, last updated 10 July 2026 - the most recent in this batch - with the company's Corporate Governance Guidelines alongside.
確認メモ（原文・英語）The English 164th AGM notice (June 2026) gives the seven Proposal 2 candidates with dated career histories (so tenure as director is readable), nomination reasons describing expertise, board attendance, shareholdings, and for the three external candidates 'Years of service' (8, 5, 2 years) and TSE independent registration plus the company's independence criteria. The Audit and Supervisory Committee directors were not up for election this year; the business report lists them with positions and a note on expertise (e.g. Yukiko Fujikawa's accounting background), not full biographies. Re-checked 21 Oct 2026 under v1.1.1: an AGM candidate list covers the board when every sitting director is a candidate or is profiled elsewhere in English on the company's site. The Audit and Supervisory Committee directors are profiled as candidates in the English notice of the 163rd AGM (2025), still on the site. Every director covered, so 5.
確認メモ（原文・英語）'(Reference) Skills Matrix of Directors' in the English 164th AGM notice (p.15-16), for the board as composed after the June 2026 meeting, against eight areas (corporate management, sustainability, global, financial strategy and accounting, HR development, research/production/technology incl. IT and DX, sales and marketing, governance and risk), with external/independent marked and the reason for and requirements of each skill item. Current.
確認メモ（原文・英語）The English AGM notice's business report (pp.37-39) sets out the structure (monthly fixed basic compensation by rank and years in office; annual director bonus; restricted stock with a 3-year+ transfer restriction), the bonus KPIs (consolidated net sales, OP and profit, plus MTP sustainability indicators: eco-friendly product sales and GHG emissions), the target pay mix by rank (President 51% basic / 19% bonus / 30% RS), the process via the Nomination and Remuneration Committee, and total amounts paid (directors 308m yen: 174 basic, 70 bonus, 63 stock). No weights for the bonus KPIs, which are 'comprehensively considered'. Structure, KPIs and amounts, KPI weights missing.
確認メモ（原文・英語）Notice of the 164th AGM in English, 95 pages with every proposal's reference documents, sixteen candidate profiles and the business report in full - but the English was posted on 3 June 2026 (PDF created 2 June) for a meeting on 19 June, 16 days ahead, against electronic provision of the Japanese from 22 May. About two weeks: 4 (was 5, which counted from the Japanese date; re-checked 14 Oct 2026).
確認メモ（原文・英語）The English shareholders' meeting materials page carries one document for the 164th term - the convocation notice - and a back-number link. No resolution notice and no voting results in English.
確認メモ（原文・英語）The English Corporate Governance Report (10 Jul 2026), Principle 1.4: holding rationale, annual board verification against stock price, dividends and results, and the year's sales (13 stocks sold, holdings down 9 stocks / 1,763m yen). ADEKA Report 2025 (English, p.15) adds that eight stocks were sold in FY2024 leaving 89 stocks, with a table of amounts held and 32 stocks / 3.48bn sold since FY2014 (a 16% decrease). No reduction target or schedule, only 'reduce ... as appropriate'. Policy and numbers, no target.
