確認メモの要点（当調査による日本語要約）2026年6月30日までの3か月の要約決算が2026年8月13日に日本語と同時に英語で公表されていますが、8ページ（日本語10ページ）で「一部を翻訳」とあり、セグメント情報などの注記がありません。毎期セグメント注記が欠けるため3点です（2026年10月23日再確認、9月は5点）。

確認メモ（原文・英語）[Summary] Consolidated Financial Results for the Three Months Ended June 30, 2026, 13 August 2026 with the Japanese, but 8 pages against the Japanese 10 and 'translated from a part of the Japanese original': summary, qualitative information and statements, ending at the statement of comprehensive income - without the Japanese notes section (going concern, specific accounting, segment information). The full-year release (13 May 2026, 16 pages) likewise ends at the cash flow statement with no segment note. Every quarter is in English, but each one drops the segment note. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 5 without a note.

確認メモの要点（当調査による日本語要約）最新四半期の英文短信は8ページで一部翻訳と記載され、要約、定性的情報、財務諸表のみで注記がありません。通期も英語16ページ対日本語17ページで注記がなく、毎期注記が省かれるため3点です（2026年10月23日再確認）。

確認メモ（原文・英語）Q1 FY3/2027 tanshin, 13 Aug 2026: the English '[Summary] Consolidated Financial Results for the Three Months Ended June 30, 2026' is 8 pages against the Japanese 2027年3月期 第1四半期決算短信 at 10, and says it is 'translated from a part of the Japanese original'. It carries the summary pages, the qualitative section (results, sales by market, region and product, financial position, forecast) and the balance sheet, income and comprehensive-income statements, then stops. The Japanese section (3) 四半期連結財務諸表に関する注記事項 (going concern, specific accounting, セグメント情報等) is not in the English. The year-end release (13 May 2026) is the same: 16 English pages against 17 Japanese, ending at the cash flow statement without the notes (継続企業の前提, セグメント情報等, p16 of the Japanese). The notes are cut every period, so 3. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 5 without a note.

確認メモ（原文・英語）The latest quarter (Q1 FY3/2027, 13 Aug 2026) has condensed statements in English (balance sheet, income, comprehensive income) but none of the notes, which exist only in the Japanese tanshin. Full statements and notes exist in English only at the year end: Financial Review 2026 (28 Sep 2026, 45 pp) has the balance sheets, income, comprehensive income, changes in net assets and cash flows for the year to 31 March 2026, notes 01-40 (accounting policies, financial instruments, retirement benefits, income taxes, segment information, per-share amounts, subsequent events) and the translated Independent Auditor's Report. Full statements and notes at the year end only, so 4. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 5 without a note.

確認メモ（原文・英語）No annual securities report in English. Financial Review 2026 (28 September 2026, 45 pages) carries the consolidated financial statements, notes and the translated Independent Auditor's Report for the year to March 2026, but none of the narrative parts of the yuho (business overview, risks, MD&A, facilities, governance).

確認メモの要点（当調査による日本語要約）単一セグメントであることは期末のFinancial Review 2026で英語に記載され、製品別・地域別売上もあります。各四半期の英文短信も市場別・地域別・製品別の売上を示しますが、単一セグメントの記載は期末のみのため4点です。

確認メモ（原文・英語）Sanken has one reportable segment. Financial Review 2026 note 36 says so in English ('our group is a single segment of the semiconductor device business'), with sales by product (power modules ¥40,554m, power devices ¥38,056m, others ¥1,564m) and by region, and it explains the reclassification of Allegro products and the former unit business into 'Others' with restated prior-year figures. Every English quarterly tanshin gives net sales by market (automotive, white goods, industrial/consumer, others), by region and by product in the qualitative section, e.g. Q1 FY3/2027 automotive ¥7,052m, white goods ¥8,726m, power modules ¥9,105m, power devices ¥9,574m. The decks add quarterly sales by market and Sanken Core versus Others operating profit. But the single-segment statement only appears in English at the year end, because the quarterly English tanshin drop the segment note (as at 6525). Every period, definitions stated only annually, so 4. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

The English IR News List, Financial Report, Presentation Slides and Sanken Report pages link only PDFs, including the two-page bilingual 'Supplementary Information (Data)' PDFs each quarter and the 11-year financial data page of Sanken Report 2025.

確認メモの要点（当調査による日本語要約）英文の通期短信が2027年3月期予想（売上865億円、営業利益14億円など）と想定為替155円/ドル、市場観を示し、英文資料が上期・下期の予想、市場別売上予想、為替感応度を加え、修正理由も英語のため5点です（2026年10月23日再確認、9月は4点）。

確認メモ（原文・英語）The FY3/2026 English tanshin (13 May 2026) gives the FY3/2027 forecast: net sales ¥86.5bn, operating profit ¥1.4bn, ordinary ¥0.1bn, net ¥1.0bn, 'based on the assumed foreign exchange rate of 155 yen to the US dollar'. Its section (4) 'Forecast for the future' explains the market view (challenging environment, ICE/hybrid demand, automotive air-conditioning modules) and the H1 loss / H2 recovery logic. The English FY deck (15 May 2026) adds H1/H2 forecasts (H1 OP -¥2.4bn, H2 +¥3.8bn), the market environment by automotive, white goods and industrial/consumer, sales forecasts by market, an OP bridge by factor and the FX sensitivity (about ¥0.4bn sales and ¥0.13bn OP per ¥1/USD). Revisions are explained in English: 'Notice of Differences Between Forecast and Actual Results for the Six Months Ended September 30, 2025, and Revision of the Full-Year Financial Results Forecast' (11 Nov 2025, same day as the Japanese) gives the reasons. The Q1 FY3/2027 tanshin says the forecast is unchanged. FX, market view and market-level forecasts plus explained revisions, so 5. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 4 without a note.

確認メモの要点（当調査による日本語要約）現行の24中計は英文の資料で示され、Allegroの連結除外後の目標（2028年3月期のサンケンコア売上875億円、営業利益率4%以上など）は英文の通期資料（25ページ、日本語と同じ）にあり、TDnetでは同時刻のため5点です。

確認メモ（原文・英語）The current plan is the 2024 Medium-Term Management Plan (24 MTP). It was launched in English in the FY2023 results deck ('Financial Results Presentation Fiscal Year Ended March 2024', 13 May 2024, 27 pp, PDF created the same day), which set out the targets (consolidated FY27 sales ¥250bn+, OPM 20%+, then including Allegro) and the Sanken Core growth scenario. After Allegro left consolidation, the current targets are in the English FY3/2026 deck ('Fiscal Year March 2026 Q4 Financial Results', 25 pp like the Japanese 25): pp19-21 revise the FY3/2028 Sanken Core targets from net sales ¥100.0bn+ and OPM 10% to ¥87.5bn and 4%+, with break-even points (¥79.0-82.0bn), FX assumptions (¥145-155) and the target sales mix (xEV 18%, ICE 22%, white goods 46%, industrial/consumer 14%), matching the Japanese p19. TDnet (kabutan) shows the English and Japanese decks at the same minute, 15 May 2026 15:30, though the English PDF now on the site is dated 4 June 2026 (probably a replaced file). Complete and same day by the listing, so 5. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

確認メモ（原文・英語）Sanken holds briefings at the half year and the full year, and English decks exist for both: Q2 FY March 2026 (19 pages, listed 12 November 2025, file dated 20 November) and Q4 Financial Results (25 pages like the Japanese, listed 15 May 2026, file dated 4 June). Q1/Q3 get the same market-environment and data supplements in English as in Japanese. The Japanese side adds only audio streams (a medium). Every period, but the English files are dated one to three weeks after the Japanese; the listing dates say same day, so the floor is recorded. Re-checked 16 Oct 2026: the FY3/2026 deck went on TDnet in English and Japanese at the same minute (15 May 2026 15:30), but the H1 FY3/2026 English deck went on TDnet only on 18 November 2025 as "[Delayed] Fiscal Year March 2026 Q2 Financial Results" (https://ssl4.eir-parts.net/doc/6707/tdnet/2721975/00.pdf), six days after the Japanese, although the English site lists it on 12 November. The 4 stands on that evidence. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 5 without a note.

確認メモの要点（当調査による日本語要約）英文のSanken Report 2025冒頭にサンケンの特色とサンケンコアの存在感の章があり、IPMの世界シェア11%（世界4位）などを示します。2026年10月21日の再確認で、市場順位を数値化された強みとして5点です。

確認メモ（原文・英語）Sanken Report 2025 (English, 49 pp) opens with 'What Makes Sanken Electric Unique' and 'The Presence of Sanken Core': Sanken Core sales by product and an 11% world share in IPMs (No. 4 in the world, No. 3 in Japan, Fuji Keizai). The FY3/2026 deck ends with a 'Market Position' page. Re-checked 21 Oct 2026; the September index record scored this without a note. Under the S3 reading applied to the cohort on 21 Oct, a section in an investor document counts the same as a page and a named market rank counts as a quantified strength. So 5.

確認メモの要点（当調査による日本語要約）英文の24中計資料がパワー半導体市場のCAGRや車載売上比率50%超の目標を示し、通期資料が875億円目標の売上構成、営業利益の増減要因、IPMシェアなどで成長要因を数値化しているため5点です。

確認メモ（原文・英語）The drivers are named and numbers are attached in English. The 24 MTP deck (13 May 2024, pp14-20) gives the power-semiconductor market CAGR (Omdia 7-8% 2022-27, Yole 8.1%, Fuji Keizai 7.8%), a target automotive sales ratio above 50%, and growth strategies by market (xEV traction-motor modules, ICE, white goods, industrial) and by product (power modules, power devices, traction-motor modules). The FY3/2026 deck (15 May 2026) quantifies each one: the FY3/2028 sales mix behind the ¥87.5bn target (xEV 18%, ICE 22%, white goods 46%, industrial/consumer 14%, against the earlier xEV 25% plan), market-level sales forecasts, the OP bridge (production volume +¥3.7bn, pricing/metal switch +¥2.3bn, cost reduction), IPM share 10% (No. 5 globally), CY2026 OEM production of 93M vehicles and IPM adoptions by three Indian air-conditioner makers. Named drivers with numbers, so 5. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

確認メモ（原文・英語）The previous plan (21 MTP, FY21-23) is reconciled in English in the FY2023 results deck (13 May 2024), p16 'Review of 21 MTP'. The consolidated targets are set against results: sales ¥235.2bn against the ¥170bn+ target, OPM 12% (FY22) and 8% (FY23) against 13%+, ROE 'below target' against 12%+, and Sanken Core's new-product share against its 15% target. It explains why the Sanken Core target was missed: external reasons (market conditions, exchange rates, high costs), internal reasons (a falling new-product launch rate, vulnerabilities in the plan) and the major factors (pandemic demand, supply-chain turmoil, the weak yen, the Noto earthquake). P17 sets the 21 MTP evaluation against the 24 MTP measures. The current plan's own revision is also explained in English (FY3/2026 deck pp19-21: 100.0bn+/10% revised to 87.5bn/4%+, citing the EV chasm and China white goods). Targets against actuals with the variances explained, so 5. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

確認メモ（原文・英語）The English notice of the 109th AGM (June 2026, 66 pp) profiles all nine candidates: eight directors who are not Audit and Supervisory Committee members (Takahashi, Kawashima, Utsuno, Seki, Yanagisawa, Ohara, Sato, Kishinami) and one ASC member (Sugawara). Each has a dated career history, shares held, reasons for nomination and, for external directors, '<Independent Officer>' and the term of office (e.g. Seki 'One year as of the closing of this meeting', Sugawara 'Two years'). A board composition table covers all eleven directors with independence, committee roles and attendance. The two continuing ASC members (Kato, Ogose) get no career profile there, and Sanken Report 2025's Board of Directors page shows names and titles only. All three elements, but full profiles for candidates only, so 4. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

確認メモ（原文・英語）The English 109th AGM notice (p4, June 2026) has 'Skills matrix under the new management structure'. It covers all eleven directors after the meeting (three inside directors, five external directors, the full-time ASC member and two external ASC members) against seven skills: corporate management, finance/accounting, industry knowledge, ESG, DX, global operations, risk management/compliance. The skills are defined, and the notice says how the Nomination Committee uses the matrix. Sanken Report 2025 also has 'Skills Matrix of Directors and Definitions of Each Skill'.

確認メモ（原文・英語）The English 109th AGM notice business report ('4. Compensation payable to Directors', pp24-26). Structure: basic compensation 60%, short-term incentives 27% and long-term stock compensation 13% at full target achievement, each varying 0-150%. External directors and ASC members get fixed pay only. KPIs: consolidated operating profit etc. plus individual indicators for the short term; consolidated operating profit, consolidated ROE, relative TSR against the TOPIX electric appliances index, and ESG items for the long term. FY targets against actuals: OP ¥0.4bn target against -¥4.7bn actual, ROE -3.2% against -7.3%. Amounts by pay type and director category: ten non-ASC directors ¥159m (basic ¥132m, short-term ¥18m, share ¥9m), external ¥51m, ASC members ¥48m. Re-checked 21 Oct 2026 under v1.1.1, which needs the weight of each performance measure in every performance-linked element: the short- and long-term plans name several KPIs each with no weights (only the pay mix is given).

確認メモ（原文・英語）English treatment is policy only. The English Corporate Governance Report (Last Update 3 July 2026), [Principle 1-4 Cross-Shareholdings], says the company may hold shares in business partners to maintain relations, regularly examines each holding's rationale and 'reduces its holding of those shares when it determines it is not rational to hold them', and gives voting criteria. Sanken Report 2025 'Cross-Shareholdings' repeats this and adds that the board verifies each holding every year. No count of holdings, no amount, no reduction target or progress anywhere in English: the Financial Review shows only total 'Investment securities: Other securities' (¥2,088m), and the yuho's 株式の保有状況 is Japanese-only.

確認メモの要点（当調査による日本語要約）英語のトップ、IRトップ、IRニュース一覧、IR資料、決算、説明資料、業績、株式情報、株主総会、IRカレンダーなどは全て内容が表示されたため5点です（2026年10月23日再確認、9月は4点）。

確認メモ（原文・英語）We rendered these English pages in Chrome: homepage, IR top, IR News List (with its year selector and category filters exercised), IR Materials, Financial Report, Presentation Slides and Sanken Report (year selectors exercised back to FY2020/2021), Business Performance (charts and tables), Stock Information, Basic Information, General Meeting of Shareholders, IR Calendar (2025 and 2026 schedules), Terms of Use and Disclosure Policy. Every list and table rendered its content. The only external widget is a 'Stock Prices' link to a third-party quote service (stockweather, plain http), which is not an IR rendering failure. So 5. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 4 without a note.

確認メモの要点（当調査による日本語要約）英語のIRニュース一覧は2004〜2026年の年選択と種類の絞り込みがある日付付きのページですが、TDnetで同日に英語で出た補足資料の一部が掲載されていません。完全ではないため4点です。

確認メモ（原文・英語）The English IR News List (corp/en/news/ir.htm) is one dated page with a year selector (2004-2026) and working category filters (All, Financials, IR/Company Announcements, General Meeting of Shareholders, IR Information). It carries tanshin, supplements, decks, Sanken Reports, Financial Reviews, AGM notices, CG reports and timely disclosures. IR Materials also splits the same documents into Financial Report, Presentation Slides and Sanken Report pages, each dated by fiscal year. But the page does not list every English document: the English FY3/2026 Q1 and H1 'Supplemental Financial Data' and the Q3 'Supplementary Information (Market Environment)' and '(Data)', all on TDnet in English the same day (kabutan), appear on neither the news list nor the Financial Report page. One dated, typed page, not complete, so 4. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

確認メモ（原文・英語）The archive is deep across types. IR News List years back to 2004. Financial Report from FY2004 to FY2026 (e.g. FY2020 quarterly results and supplemental data, all four FY2024 quarters). Presentation Slides from FY2013, with FY2020 Q1-FY decks rendered. Sanken Report / Financial Review editions from 2004 (2021, 2022, 2024, 2025, 2026 opened). AGM notices from the 101st to the 109th. Several years across document types, so 5. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 4 without a note.

確認メモの要点（当調査による日本語要約）英語IRトップに「Inquiries about IR」のタイルがあり、FAQとIR専用のメールアドレスに届きます。専用で分かりやすいため4点です。

確認メモ（原文・英語）The English IR top (corp/en/tousika/) has an 'Inquiries about IR - Frequently Asked Questions and IR contact information' tile among its five main tiles, and 'Inquiries about IR' in the IR menu. It leads to an FAQ and to 'Inquiry (Investor Relations)', which gives a dedicated address: 'Email address for IR-related inquiries: ir@sanken-ele.co.jp'. The site-wide Contact Us page is not a single form: it splits into Products, 'Inquiries about Investor Relations' (linking back to the same IR page) and Other Inquiries. The tanshin contact is Takuya Iwata, Manager, Investor Relations Department, +81-48-472-1111. Dedicated and immediately obvious. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

確認メモの要点（当調査による日本語要約）英文短信は毎期日本語と同日・同時刻ですが（例：2026年8月13日15時30分）、中間の英文資料はTDnetに6日遅れで提出されました。短信は同日、資料は時に遅れるため4点です。

確認メモ（原文・英語）Timestamps from TDnet (kabutan's disclosure list) and the two IR news lists. Tanshin same day every period read: Q1 FY3/2027 13 Aug 2026 15:30 both; FY3/2026 13 May 2026 15:30 both; Q3 9 Feb 2026 15:30 both; H1 11 Nov 2025 15:30 both. The English tanshin are the cut-down '[Summary]' versions (see F2), but no fuller English follows later. Decks: FY3/2026 English and Japanese both on TDnet 15 May 2026 15:30, though the English PDF now served is dated 4 June. H1 FY3/2026: Japanese 12 Nov 2025, English on TDnet as '[Delayed] Fiscal Year March 2026 Q2 Financial Results' on 18 Nov 2025 (6 days; the English site lists it as 12 Nov, file created 20 Nov). Tanshin same day, deck sometimes later, so 4. (Note from the October cohort record, checked 12-16 Oct 2026; the September record gave the same score without a note.)

確認メモ（原文・英語）Lags, English against Japanese, from TDnet/kabutan and the IR news lists. Q1 FY3/2027 tanshin: 13 Aug / 13 Aug 2026 = 0. FY3/2026 tanshin: 13 May / 13 May = 0. 109th AGM notice: 3 Jun / 3 Jun 2026 (both on TDnet at 08:00) = 0. Corporate Governance Report: Japanese 3 Jul 2026, English '[Delayed]' 23 Jul 2026 = 20. Annual securities report: Japanese 24 Jun 2026, no English (Financial Review 2026 has only the financial statements, so it does not count) = >90. Sorted 0, 0, 0, 20, >90: median 0, so 5.

確認メモの要点（当調査による日本語要約）2025年10月16日から2026年10月15日まで、業績予想修正、事業提携、役員異動などの適時開示は全て同時刻に英語版があります。日本語のみは独立役員届出書のみのため5点です（2026年10月23日再確認）。

確認メモ（原文・英語）TDnet list on kabutan, 16 Oct 2025 to 15 Oct 2026, against the English IR news. Besides results, supplements, decks, AGM papers and the CG report, the Japanese timely disclosures are: the H1 forecast difference and full-year revision (11 Nov 2025), the Minebea Power Semiconductor Device power-module collaboration (27 Jan 2026), changes in directors and corporate officers (13 May 2026), and the policy on lowering the investment unit (13 May 2026). Each has an English version on TDnet at the same minute and on the English IR news list the same day. The only Japanese-only TDnet item is the 独立役員届出書 (independent officer notification, 3 Jun 2026), a TSE filing rather than a timely disclosure of the types counted. The previous 12 months' buyback notices also had same-day English. All same day, so 5. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 4 without a note.

確認メモの要点（当調査による日本語要約）英語のトップ、IRトップ、IRニュース、利用規約、開示方針に機械翻訳の注記はなく、文書の優先条項はR5の対象のため5点です（2026年10月23日再確認、9月は3点）。

確認メモ（原文・英語）We rendered the English homepage, IR top, IR News List, Terms of Use and Disclosure Policy and searched the visible text: no machine- or AI-translation notice and no translation pop-up. The site's language switch (日本語 / English / 中文) points to separately written sites. The documents carry only human-translation precedence language ('translated from the Japanese original for reference purposes only ... the original shall prevail'), which belongs to R5. So 5. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 3 without a note.

確認メモの要点（当調査による日本語要約）決算短信、決算説明資料、招集通知には「原文が優先する」旨の記載がありますが、コーポレート・ガバナンス報告書、統合報告書、Financial Reviewにはありません。一部の資料のみの断り書きです。

確認メモ（原文・英語）The tanshin, both results decks and the AGM notice each say 'In the event of any discrepancy ... the original shall prevail'. The Corporate Governance Report, Sanken Report 2025 and Financial Review 2026 carry no such statement. Disclaimed on some documents. Re-checked 23 Oct 2026 against the October cohort record; the September record scored 1 without a note.
