確認メモ（原文・英語）Consolidated Financial Results for the Nine Months Ended June 30, 2026, posted 6 August 2026, the same day as the Japanese 決算短信. It runs 11 pages against the Japanese 14 and has the qualitative overview of operating results, financial position and forecasts, the statements, and the notes, including the full segment information. The Japanese adds only the voluntary auditor's quarterly review report. Q1 (5 February, 10pp) and Q2 (14 May, 12pp vs 12) were also same-day, and the FY2025 release (7 November 2025) runs 24 pages against 25. Every period is same-day and complete apart from that review report.

確認メモの要点（当調査による日本語要約）第3四半期の英文短信（2026年8月6日、11ページ）は、日本語の14ページに対し、税金費用の計算、継続企業の前提、キャッシュ・フローに関する3つの短い注記を省いています。注記の一部が欠けているため3点です（2026年10月16日見直し）。

確認メモ（原文・英語）Latest tanshin, Q3 FY2026, 6 Aug 2026. The English 'Consolidated Financial Results for the Nine Months Ended June 30, 2026' is 11 pp; the Japanese 2026年9月期 第3四半期決算短信 is 14 pp. Both have the summary pages and the qualitative overview (results, financial position, the forecast revision and its reasons). Both have the balance sheet, income statement and comprehensive income statement. Both have the segment note, with sales by region and segment profit and its reconciliation, and the note on significant changes in equity (the buyback). The English leaves out three short Japanese notes. The first is the tax-expense computation note (the cover page only says 'Yes'). The second is the going-concern note ('none'). The third is the cash-flow note, which gives nine-month depreciation of ¥14,091m and goodwill amortisation of ¥2,849m (depreciation is in the English databook). The English also omits the voluntary review report (pp.13-14), which does not count. Q2 (12 pp against 12) and the FY2025 year-end tanshin (24 pp against 25, with the segment definitions, per-share and subsequent-events notes) are complete. The English is whole in substance but trims a few boilerplate notes in Q3. That fits neither band exactly; We chose 4 over 3 because nothing material is only in Japanese. Set to 3 in review (16 Oct 2026): F2 is the page-for-page test, and the latest English tanshin cuts three of the Japanese notes (tax computation, going concern, the cash-flow note) - a cut to the notes is band 3 (as for Tokuyama, 4043), and the floor is taken where the cut is small.

確認メモの要点（当調査による日本語要約）第3四半期の英文短信に、貸借対照表、損益・包括利益計算書と、セグメント情報などの注記があります。通期の英文短信にはキャッシュ・フロー計算書や1株当たり情報などもあります。

確認メモ（原文・英語）The latest-period English tanshin (Q3 FY2026, 6 Aug 2026) has the full quarterly statements: balance sheet, income statement and comprehensive income statement. Like the Japanese, it has no cash-flow statement for Q3. It has the notes: segment information for both periods, with revenue by region and customer type, segment profit and the reconciliation to operating profit, and the equity-change note on the treasury-share purchase. The FY2025 English year-end tanshin (7 Nov 2025, 24 pp) adds the cash-flow statement, changes in equity, accounting-policy changes, per-share data, subsequent events and non-consolidated statements. Full statements and notes for the latest period, so 5.

確認メモの要点（当調査による日本語要約）4つの報告セグメント（電子管、光半導体、画像計測機器、レーザ）とその他の売上高（地域別）とセグメント損益を英文短信の各期に開示し、通期の注記で区分の定義も示しています。

確認メモ（原文・英語）There are four reportable segments: Electron Tube, Opto-semiconductor, Imaging and Measurement Instruments, and Laser, plus Other. Every English tanshin gives each segment's sales, broken down by region, and segment profit (loss), with the adjustment to operating profit. For example, Q3 FY2026 YTD segment profit was 17,897 / 12,741 / 6,857 / (4,896) ¥m. The FY2025 year-end segment note states the definitions: the segments are based on products and services, with a description of what each makes; segment profit is on an operating-profit basis; and intersegment transfers are at market prices. The FY2024 reclassification of stealth dicing into Laser is explained, with the prior year restated. The decks add segment results and forecasts (Q3 FY2026 pp.27-30), and the bilingual databook adds quarterly segment sales and profit back to FY2022. Every period, definitions stated, so 5.

確認メモ（原文・英語）Every quarter's English library row has a 'Data book' .xlsx: h_ir_79q_3rd_databook.xlsx (6 Aug 2026), with the 1st/2nd FY2026 and all four FY2025 files, and FY2024 Q2-Q4. It is the same bilingual file the Japanese library links. It has 11 sheets: Index, Notes, Notes on reclassification, Financial results, Sales by application, Sales by business segment, one sheet each for the four segments, and Capex/R&D/Depreciation. Financial results is a quarterly and half-yearly P&L (sales through net profit plus USD/EUR/RMB rates) for FY2022-FY2026, five fiscal years. The segment sheets give sales, cost, SG&A, R&D and segment profit. There is no balance sheet, no cash flow and no per-share data. Those are only on the HTML 'Financial highlights' table (FY2020-FY2025), which does not count. Before FY2024 the data book was a PDF. A spreadsheet that is narrower than the full set of statements, so 4.

確認メモ（原文・英語）The Q3 FY2026 English tanshin (6 Aug 2026) revises the full-year forecast (sales ¥239.0bn, OP ¥22.0bn) against the 14 May forecast, in a table. It gives the reasons: firm semiconductor and AI data-centre demand in industrial equipment, yen weaker than assumed, and Middle East raw-material and energy risk. The English Q3 deck (32 pp, same day) sets the revised against the previous forecast and YoY. It gives the assumed rates (USD/JPY 158.25, EUR/JPY 183.43, CNY/JPY 22.10), FX sensitivity, and revised forecasts by segment (pp.26-30) and by application. The FY2025 deck likewise gave the FY2026 plan with FX assumptions, application forecasts and a bridge. Forecast, FX, market view and segment forecasts, with revisions explained, so 5.

確認メモの要点（当調査による日本語要約）日本語のスクリプト（質疑応答付き）にはすべて英文がありますが、2025年度の英文の質疑応答は日本語より遅れて公表されたため4点です（ファイル名の日付による）。

確認メモ（原文・英語）Every Japanese results-briefing script (スクリプト付き, with the full 質疑応答) has an English counterpart with the same Q&A. Q3 FY2026: 22 pp against 22, 17 questions on both sides, both PDFs created 18 Aug 2026. Q2: 12 pp against 13, Q1-Q5. Q1: 15 against 11. FY2025: 33 against 28, Q1-Q12. The March 2026 Laser business briefing script is in English too. The FY2026 scripts share filename dates (260211, 260521, 260819) and creation dates on both sides. For FY2025 the filenames, which track posting dates on this site, are later in English: year-end Japanese h_ir_251113_se against English h_ir_251124_se_en (about 11 days), and Q3 250819 against 250820. Neither script is in the IR news lists. Every period covered, but the FY2025 English Q&A came after the Japanese, so 4 under the ruling (floor; the evidence is the filename dates).

確認メモ（原文・英語）2025 Integrated Report in English, 28 pages, matching the Japanese 28. Its reporting period is FY2025, the year ended September 2025, and it has the financial statements and the nine-year summary. That is the current edition for a September year-end, since FY2026 closed only on 30 September. Judged by PDF creation dates (no posted date): the English file is from May 2026, the Japanese from March 2026. Re-scored 23 Oct 2026 under the owner's S6 ruling of that day (currency is judged against the latest closed year on the day of the check): the report covers FY2025, the year ended September 2025, and FY9/2026 closed on 30 September 2026, before the 12 Oct check.

確認メモの要点（当調査による日本語要約）前回の計画（2024年度スライド：2027年度売上高2,591億円、営業利益377億円等）は2025年11月に新計画に置き換えられましたが、日英のスライドとも旧目標と実績の対比や引下げの理由はなく、英文では2025年度の説明会台本で3年計画を毎年更新している旨の説明があるのみです。

確認メモ（原文・英語）The previous plan was the rolling FY2025-FY2027 plan in the FY2024 English deck (8 Nov 2024): FY2027 sales ¥259.1bn, OP ¥37.7bn (14.6%), EBITDA ¥62.0bn, ROE above 8%, and FY2030 sales ¥300bn. In November 2025 it was replaced by the FY2026-FY2028 plan (¥262.0bn, ¥33.6bn, ROE above 8% in FY2028). Neither the English nor the Japanese FY2025 deck (51 pp each) sets the old targets against actuals or explains the cut. FY2025 actuals are compared only with the Q3 forecast. The only English treatment is the FY2025 briefing script. It says 'We have been creating three-year plans on a rolling basis each year, but from now on, we will analyze the gaps between our mid-term plans and actual results', and its Q&A explains the FY28 profit step-up. A mention without a target-against-actual reconciliation, in either language, so 2.

Each also has the reason for nomination, which states the expertise. For the four outside directors (Kurihara, Hirose, Minoshima, Kimura) it states that each is filed with the TSE as an independent officer, with the transactional-relationship assessment.

It also gives the caps (¥720m a year; RS up to ¥200m). It sets out the structure: fixed, short-term performance-linked and restricted stock at a standard 70:15:15, with outside directors on fixed pay only. It gives the KPI and how it works: the short-term pay is indexed to consolidated operating income. The coefficient is 1 within ±5% of the prior year, varies within ±30%, and is zero if OP falls more than 30%. Restricted stock carries a 30-year transfer restriction, and pay is set by the board after the majority-outside Nomination and Compensation Committee.

It has AGM notices from the 67th to the 78th, Annual Reports 2014-2019, Integrated Reports 2019-2025 (2020-2021 in Japanese only), databooks from FY2019, and IR news 2022-2026. Several years across types, so 5.

確認メモの要点（当調査による日本語要約）英文IRトップの「Contact us」から、問い合わせの種類が投資家に設定された共通のフォームに進みます。分かりやすいものの、IR専用ではないため3点です。

確認メモ（原文・英語）The English Investors top page's 'Contact us' link opens the site inquiry form with 'Type of request: Investors' already set, an IR route one click from the IR top, but into the shared site form. The support contact page also has an 'IR Inquiry' entry. The tanshin names Takashi Ogasawara, Executive Officer and Chief of Finance and Accounting General Headquarters, +81-53-452-2141. Obvious, but a shared form with an IR category rather than a dedicated route (as Yokogawa, 6841): 3.

確認メモの要点（当調査による日本語要約）各期とも、英文の決算短信は日本語と同時刻にTDnetで開示され、説明資料も日本語と同じ日に掲載されています。

確認メモ（原文・英語）The tanshin went out at the same time in both languages on TDnet (kabutan list), at 15:30 each time. That covers Q3 FY2026 (6 Aug 2026), Q2 (14 May), Q1 (5 Feb) and FY2025 (7 Nov 2025), and Q3 FY2025 (7 Aug 2025). The English IR news lists the English deck on the same day as the Japanese IR news lists the Japanese one. Q3 FY2026: 'Hamamatsu Summary Report' 6 Aug, Japanese 決算説明会資料 6 Aug. Q2: 14 May on both. Q1: 5 Feb on both. FY2025: 'Presentation Materials' 7 Nov, Japanese 配布資料 7 Nov. Q3 FY2025: 7 Aug on both. The current English PDFs of the Q3 FY2025 and FY2025 decks were created later (7 Oct and 4 Dec 2025). The FY2025 Japanese deck was re-made on 4 Dec too, so these look like replacements and the listing dates are used. Tanshin and deck same day every period, so 5.

確認メモの要点（当調査による日本語要約）資料ごとの日英の時差は、四半期の短信、招集通知、ガバナンス報告書が0日、英文のない有価証券報告書が90日超で、中央値は0日です。

確認メモ（原文・英語）Lags, English against Japanese, from TDnet times and the IR news lists. Q3 FY2026 tanshin: 6 Aug / 6 Aug = 0. Q2 FY2026 tanshin: 14 May / 14 May = 0. 78th AGM notice: 24 Nov / 24 Nov 2025 = 0 (both on TDnet at 08:00). Corporate Governance Report: 24 Dec / 24 Dec 2025 = 0 (Japanese 15:48, English 17:00). Annual securities report: Japanese 18 Dec 2025 (corrected 26 Dec), no English, so more than 90. Sorted 0, 0, 0, 0, >90: the median is 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〜2026年10月16日の対象となる適時開示は、すべて同じ日に英文でもTDnetに開示されています。英文のないものは独立役員届出書などの対象外の書類です。

確認メモ（原文・英語）TDnet list (rendered on kabutan), 16 Oct 2025 to 16 Oct 2026. Every Japanese disclosure has an English one filed the same day. Buyback decision, 7 Nov 2025 15:30, with English at the same minute. Monthly buyback status, 1 Dec and 5 Jan, 2 Feb, 2 Mar, 1 Apr, 1 May, 1 Jun, 1 Jul, and completion on 3 Aug 2026: English at the same minute every time. Restricted-stock issuance, 19 Dec 2025 (Japanese 16:30, English 18:10), and its payment completion, 16 Jan 2026. Director-candidate and executive-officer changes, 25 Sep 2026 (both 15:30; English also in the site's Announcements). Also the results, AGM notice and CG report, all same day. All but the forecast revision and the buyback decision are also on the English IR news list. Two items have no English. One is the 独立役員届出書 (independent-officer filing form, 25 Nov 2025), a statutory form rather than a disclosure of the types counted. The other is the company-site notice of the corrected yuho (26 Dec 2025), which was not on TDnet. Every counted disclosure in English the same day, so 5.

確認メモの要点（当調査による日本語要約）英文サイトや資料に、機械翻訳である旨の表示はありません。資料の「原文が優先する」などの記載は、R5で扱っています。

確認メモ（原文・英語）We rendered the English homepage, IR top, IR library, disclosure policy, Disclaimer and Terms of Use, and searched the visible text. There is no machine- or AI-translation notice, banner or pop-up; the only pop-up picks the region and language. The documents carry only human-translation precedence lines (the AGM notice's 'the latter shall prevail', and the CG report's 'English translation of the original Japanese document'), which belong to R5. So 5.

確認メモの要点（当調査による日本語要約）招集通知は「非公式の英訳で日本語が優先する」、ガバナンス報告書は「日本語原文が優先する」としていますが、決算短信、スライド、説明会台本、統合報告書には記載がありません。一部の資料が劣後する扱いです。

確認メモ（原文・英語）The AGM notice says it is an 'unofficial English translation... the latter shall prevail', and the Corporate Governance Report says 'the original Japanese document prevails'. The tanshin, the results deck, the briefing script and the integrated report carry no such statement. Disclaimed on some documents.
