確認メモ（原文・英語）Consolidated Financial Results for the Six Months (Interim Period) Ended July 31, 2026, listed 9 September 2026, the same day as the Japanese 決算短信. It runs 13 pages against the Japanese 9 and has the overview of business results, financial position and outlook, the statements and the notes, including segment information. Q1 (12 June 2026, 13pp vs 9) and the FY2025 release (11 March 2026, 26pp vs 19) were also same-day, and every quarter back through the archive is in English. Every period is same-day and complete.
確認メモ（原文・英語）The English 'Consolidated Financial Results for the Six Months (Interim Period) Ended July 31, 2026', listed 9 September 2026, runs 13 pages against the Japanese 2027年1月期第2四半期（中間期）決算短信 (9). The sections match one for one. There are the summary pages (results, financial position, dividends, forecast, notes on shares). Then 1. Overview of business results, with the narrative for each of the three segments and the forecast explanation. Then 2. the balance sheet, income statement and comprehensive income, and the notes: going concern, the income statement note, segment information, changes in shareholders' equity and subsequent events. Neither language has an interim cash-flow statement. The FY1/2026 year-end tanshin (11 March 2026) is 26 English pages against 19 Japanese. The whole tanshin, so 5.
確認メモ（原文・英語）The latest-period English tanshin (Q2 FY1/2027, 9 September 2026) has the semi-annual balance sheet, income statement and comprehensive income statement. Its notes cover going concern, the gain on reversal of FX translation adjustment (Hong Kong deconsolidation), the segment note with reconciliation for both periods, changes in equity and subsequent events. The Japanese interim tanshin has no cash-flow statement either. The year-end English tanshin (11 March 2026, 26pp) adds the cash-flow statement, the changes in equity, the change in depreciation method, impairment and the full segment note. Full statements and notes for the latest period, so 5.
確認メモ（原文・英語）The English IR Library has only the 'Summary of Financial Results' tab (tanshin and supplementary decks). The Japanese library's 有価証券報告書 tab (FY2025 yuho of 17 April 2026, and the half-year reports) has no English counterpart, and the 'semi-annual report posted' news item is Japanese-only. No securities report in English under any name.
確認メモ（原文・英語）There are three reportable segments: Tooling and Machine Tools, Electronic Parts (leadframes) and Electrical Parts (motor cores). Every English tanshin gives net sales (external and intersegment) and segment profit for each, with a reconciliation to operating profit. Examples: Q2 FY1/2027 Electrical Parts ¥89,889m and ¥8,992m, Electronic Parts ¥38,749m and ¥3,683m. The year-end tanshin (11 March 2026) defines the segments ('Electronic Parts' manufactures and sells leadframes, etc.). It also states that segment profit is based on operating profit and intersegment prices on market prices, and it quantifies by segment the effect of the change in depreciation method. The decks add per-segment OP margin, capex, depreciation and EBITDA. Every period, definitions stated, so 5.
確認メモ（原文・英語）There is no downloadable data file. Link scans of the English IR top, the IR Library (ir/ir-lib/) and Financial Highlights (ir/highlight/) for xls, csv, excel, data and download found nothing. Financial Highlights is a page of rendered bar charts for FY21 to FY25 (sales, OP, ordinary profit, net income, capex, EBITDA, ROE, ROIC, equity ratio; consolidated and by segment) with no download. The deck appendix 'Financial Highlights' (p.30 of the FY deck) is a PDF table. The Japanese library has no spreadsheet either.
確認メモ（原文・英語）The FY1/2027 full-year forecast is in every English tanshin and is explained in the deck. The 9 September 2026 tanshin gives sales ¥272.0bn, OP ¥19.5bn, ordinary profit ¥20.0bn, net ¥14.5bn and EPS ¥79.34. It refers to the same-day English 'Notice of Revision of Consolidated Earnings Forecasts for the Full Year'. The Q2 deck (pp.13-16) sets initial (Mar), previous (Jun) and revised forecasts side by side. It gives the FX assumption: full-year average US$ 158.57 yen, 2H assumed JPY158.00/USD. It gives revised forecasts by segment (sales, OP, margin, capex, depreciation, EBITDA margin) and explains the reasons for each segment's revision (volume, price mix, FX, base-material prices, one-time gains). The year-end tanshin (11 March 2026) gives the market view by segment behind the initial forecast. FX, segment forecasts and market view, with revisions explained, so 5.
確認メモ（原文・英語）English results for the six months to 31 July 2026 (Q2 of the January year-end) published 9 September 2026, the same period and day as the latest Japanese filing.
確認メモ（原文・英語）The current plan is 'Medium-Term Management Plan FY2025-FY2027' (FY1/2026 to FY1/2028), on the English Management Information page. It is 43 pages, the same as the Japanese 中期経営計画 2026年1月期-2028年1月期 (43). Both PDFs were created 11 March 2026, and the English revision notice was listed on English IR news the same day as the Japanese (11 March 2026). It opens with the 'Notice Concerning Revision of Financial Targets'. The revised FY1/2028 targets are sales ¥263.0bn (from ¥310.0bn), OP ¥15.0bn, OPM 5.7%, ROE 8.0% or higher, ROIC 5.0% or higher and 3-year capex ¥96.0bn. Per-segment targets follow, then the March 2025 plan reposted in full: growth strategies, capital allocation, cost of equity, DOE 3.0% or higher. The original plan also went up in English on 11 March 2025, the Japanese day. Complete and same day, so 5.
確認メモ（原文・英語）Every quarter has an English results deck posted the same day as the Japanese 決算補足説明資料. Q2 FY2026 (9 September 2026) runs 32 pages against the Japanese 32, with segment detail, the forecast revision and dividend policy. Q1, the full year and FY2025 Q1 to Q3 are all in English too. The Japanese side publishes no script, transcript or Q&A to match. Item for item with the Japanese.
確認メモ（原文・英語）There is no 'why invest', investment-highlights or at-a-glance page or deck section in English. The IR menu is Management Information, IR Library, Financial Highlights, General Meeting, IR Calendar, Disclosure Policy and Electronic Announcement. The job falls to the corporate 'About' page (AI-translated). It has the president's message and brand story, with the strengths described: integrated production from tooling design to product supply, and precision processing in EV motor cores and leadframes. The MTP also claims the top share in motor cores installed in BEVs, PHEVs and HEVs. These are strengths described in a company overview, not framed for an investor, so 3.
確認メモ（原文・英語）The English MTP names the drivers and puts numbers on them. Electrified-vehicle production is given a CAGR of 17.7% at plan launch, revised to 15.3% (2024 to 2027, S&P Global Mobility data), with the top share in motor cores claimed. The legacy semiconductor market is given a CAGR of 6.9%, revised to 4.7% (Gartner and WSTS). Motor-core sales are targeted to grow at a CAGR of 14.7% (revised to 7.0%, or 9.0% excluding material prices), with new-product timing pushed back about two years. There are segment sales, OP, EBITDA and capex targets (Electrical Parts ¥190.0bn sales, ¥78.0bn 3-year capex), a new Mexico plant and upfront investment costs of ¥10.0bn. Named drivers with market size, share and contribution, so 5.
確認メモ（原文・英語）Neither language publishes a transcript or Q&A. The English IR Library has tanshin and decks only. The Japanese IR資料室 has the 決算短信・決算補足説明資料 and 有価証券報告書 tabs. Neither news list, read for 2025 and 2026, has a 質疑応答, transcript or briefing summary, although the IR calendar shows analyst briefings at the full year and Q2. The Japanese side has none either.
確認メモ（原文・英語）No integrated, annual or business report in English. The English Management Information page offers the Medium-Term Management Plan FY2025-FY2027, a company video and links to the sustainability pages. The Japanese side has no integrated report either.
確認メモ（原文・英語）The English MTP, section 1 'Review of the previous medium-term management plan', sets the FY1/2025 targets against the actuals: net sales ¥254.0bn target vs ¥214.9bn, OP ¥33.0bn vs ¥16.0bn, OP margin 13.0% vs 7.5%, and 3-year capex ¥100.0bn vs ¥83.5bn. It also has the FX rate per USD for each year and a per-segment table for FY22/1 to FY25/1. It explains the misses: 'we didn't meet the final year targets of the previous MTMP due to market fluctuations and upfront investment costs'. Segment pages add EV demand, semiconductor-market weakness and raw-material list prices, and say Electronic Parts 'undershot our initial target volume'. The March 2026 revision does the same for the current plan, original against revised, with a sales bridge (-¥33bn volume, -¥11bn material pass-through). Target against actual with explanations, so 5.
確認メモ（原文・英語）Corporate Governance Report in English (21 pages, 'Updated: April 23, 2026'), linked from the English Sustainability > Governance page. It is the TSE filing format and the same update as the Japanese report posted on 23 April 2026. Judged by PDF creation date, the English file was made 15 June 2026, about seven weeks later. Current.
確認メモ（原文・英語）The English 'Notice of the 92nd Annual General Meeting of Shareholders' (15pp, 30 March 2026) covers the whole board. Both proposals are up for election: eight directors, and seven Audit & Supervisory Committee members whose terms all expire. Each candidate has a career summary, years of tenure as director (e.g. 23 years for the president, 2 years for newer directors) and board attendance. Each has reasons for nomination setting out expertise: litigation and risk management, Bank of Japan, accounting and tax, DX and governance. Outside and Independent status is marked for the five outside directors. Every director, all three elements, so 5.
確認メモ（原文・英語）The English Corporate Governance Report ('Updated: April 23, 2026', 21pp) answers Supplementary Principle 4.11.1. It refers to 'the skills matrix shown at the end of this report', and the last page has the matrix. It covers all 15 directors elected at the 22 April 2026 AGM, including the two new outside directors Makoto Shibata and Ritsuko Watanabe, marked against each skill. Current matrix in English, so 5.
確認メモ（原文・英語）The English Corporate Governance Report (April 23, 2026) sets out the structure: fixed pay, performance-linked bonus and BBT performance-linked stock for executive directors, fixed only for non-executives. The bonus formula is base x payment ratio, with payment ratio = attainment x 2 - 100, capped at 150% and zero below 75%. Attainment is OP attainment x 0.5 + net-income attainment x 0.5. The stock plan is linked to net sales, OP, ROIC and ESG (CO2), over three years. The mix by position is given (representative director 45.0/27.5/27.5). The amounts are totals only: FY2025 ¥369m for 15 directors, of which ¥297m for 8 executive-side directors and ¥72m for 7 A&SC members (¥39m for 5 outside), with no split by pay type or by director. The English AGM notice has no business report. Structure, KPIs and weights, total only, so 4.
確認メモ（原文・英語）Notice of the 92nd Annual General Meeting in English, 15 pages, posted 30-31 March 2026 (the same day as the Japanese notice; file created 24 March) for a meeting on 22 April 2026, 22 days before. It has the reference documents for both proposals (eight directors; seven Audit & Supervisory Committee directors), each candidate with career summary and reasons for nomination. The notice itself labels the internet voting website 'https://evote.tr.mufg.jp/ (in Japanese)': the English reader has every proposal but a Japanese-only voting route.
確認メモ（原文・英語）The English General Meeting of Shareholders page has the notice, the articles and the share handling regulations. English IR news has no AGM items after the notice. The Japanese news carries 決議ご通知 (22 April 2026) and 臨時報告書（議決権行使結果）(27 April 2026), neither in English.
確認メモ（原文・英語）The only English text is the Corporate Governance Report's Principle 1.4. It says shares are held to strengthen relationships, that major holdings are tested quantitatively against the cost of capital and qualitatively, that the board reviews them regularly and reduces them 'if a review has determined that the significance of holding the stock has declined', and how votes are exercised. There is no count or amount of holdings, no reduction target and no progress. The yuho, which has the numbers, is Japanese-only, and there is no integrated report. The English MTP and tanshin are silent. Boilerplate policy only, so 2.
確認メモ（原文・英語）The English homepage (www.mitsui-high-tec.com in English) has 'IR Information' as a visible item in the global header. One click lands on the IR top (/ir/), which has the latest results, IR news and the IR menu. There is also a hover sub-menu and a footer link. One click, so 5.
確認メモ（原文・英語）Sixteen English links were opened. Fourteen are English: the tanshin for Q2 and Q1 FY1/2027 and Q3 FY1/2026; the decks for Q1 FY1/2027, FY1/2026, Q3 FY1/2026 and Q2 FY1/2025; the forecast revision of 9 Sep 2026 and the subsidiary dividend notice of 14 Jul 2026; the 92nd and 91st AGM notices; the internal control policy and tax policy; and the 2023 and 2021 Q3 tanshin. The English General Meeting page's 'Articles of Incorporation (292 KB)' and 'Stock Handling Regulations (267KB)' open Japanese 定款 and 株式取扱規則, unlabelled. The English IR Calendar is also a Japanese-text image (第1四半期決算発表 and so on). Several Japanese documents, unlabelled, so 3.
確認メモ（原文・英語）All sixteen sampled English links opened as PDFs (pages and text read): the tanshin, decks, notices, AGM notices, governance policies, and the 2021 and 2023 archive tanshin. All live, so 5.
確認メモ（原文・英語）Rendered in en-US, these pages all show their content: the IR top, IR news (paginated, year archives 2021-2026), IR Library (latest and the period archive), Financial Highlights (charts by year and segment), General Meeting, IR Calendar, Disclosure Policy, Electronic Announcement ('no electronic announcement'), Management Information and Governance. A machine-translation modal and a cookie banner overlay each page but can be dismissed. Nothing blank, so 5.
確認メモ（原文・英語）The IR Library (ir/ir-lib/) has one tab, 'Summary of Financial Results' (tanshin and decks, dated, with a period archive back to the 77th period). AGM notices sit on the General Meeting page and the CG report on the Sustainability Governance page. The IR news list (news/ir/) is one dated list of every English IR item: tanshin, decks, forecast revisions, other timely disclosures, AGM notices and the MTP. Every item is tagged only 'IR', so it is untyped, and it lacks the CG report. One dated list, untyped and missing a type, so 4.
確認メモ（原文・英語）The archive is well populated. The English IR news runs from 2021 to 2026 with year archives. The IR Library archive has tanshin and decks for every period back to the 77th period (FY1/2011), and the 2021 and 2023 tanshin were opened. AGM notices go back at least to the 91st (2025) on the news list, and timely disclosures go back years. Several years across types, so 5.
確認メモ（原文・英語）There is a dedicated English 'IR/General Affairs Inquiry' form (contact/ir), reached through the global 'Inquiry' header button's contact hub ('IR Inquiry') or the site footer link 'Inquiries regarding IR and general affairs'. The IR menu itself (Management Information, IR Library, Financial Highlights, General Meeting, IR Calendar, Disclosure Policy, Electronic Announcement) has no contact link. The tanshin names Masakiyo Uike, Director, Senior General Manager of Corporate Planning & Strategy Unit, +81-93-614-1111. A genuine IR route that is not obvious from the IR section; the floor of 3/4.
確認メモ（原文・英語）Q2 FY1/2027: the English tanshin and deck were listed 9 September 2026, the same day as the Japanese (PDFs created 8 and 9 September). Q1: both were listed 12 June 2026, the same day as the Japanese (created 11 June). The FY1/2026 results (11 March 2026) and Q3 FY1/2026 (11 December 2025) were also same day on both sides. One older deck (Q2 FY1/2025, listed 10 September 2024) was created 1 October 2024, but every recent period is clean. Tanshin and deck same day every period, so 5.
確認メモ（原文・英語）Q2 tanshin: Japanese and English 9 Sep 2026, 0 days. Q1 tanshin: 12 Jun 2026 both, 0 days. AGM notice: Japanese 30 Mar 2026, English on the news list 30 Mar (the General Meeting page dates it 31 Mar), 0 days. CG report: Japanese updated 23 Apr 2026. The English carries the same 'Updated: April 23, 2026' but has no listing date, and its PDF was created 15 Jun 2026, so 53 days. Annual securities report: Japanese 17 Apr 2026, no English, so more than 90. The lags are 0, 0, 0, 53 and >90, a median of 0, so 5.
確認メモ（原文・英語）Twelve months of Japanese IR news (16 Oct 2025 to 16 Oct 2026) against the English, outside the tanshin. These have same-day English versions: the extraordinary loss and forecast-actual variance (11 Mar), the MTP target revision (11 Mar), the forecast revision and the FX gain (12 Jun), the subsidiary dividend receipt (14 Jul) and the forecast revision (9 Sep). All four tanshin were also same day. Missing in English: 役員人事に関するお知らせ (11 Mar 2026, the director nominations), and five 人事異動のお知らせ (31 Oct and 28 Nov 2025; 30 Jan, 30 Jun and 31 Aug 2026), which cover general-manager-level moves. All financial disclosures same day, one management change and minor personnel notices missing, so 4.
確認メモ（原文・英語）Every English HTML page opens an 'About Machine Translation' modal ('This site uses machine translation. Please note that it may not always be accurate and may differ from the original Japanese text') and shows a persistent 'English - Translated by AI' badge. The English site is an AI translation of the Japanese pages. The PDFs are not affected: the tanshin, deck, AGM notice, MTP and CG report are human translations with no machine-translation notice (the tanshin and notice carry only the 'original shall prevail' line, which is R5). A site-wide MT pop-up on HTML only, so 3.
確認メモ（原文・英語）The tanshin and the AGM notice each say 'the original shall prevail'. The results deck and the Corporate Governance Report carry no such statement. The English web pages are AI machine translation with a notice that they 'may differ from the original Japanese text'. Disclaimed on some documents.
Investor question: What volume, pricing and yield are required to absorb the upfront cost base? IR preparation: publish plant-level ramp, utilization and ROIC.

Mitsui High-tec plans approximately ¥110bn of three-year capex, primarily for electrical-parts capacity and international production.
資本構成
The plan acknowledges substantial upfront costs and stages monetization after new-product ramps; the selected sources provide less explicit leverage and return-of-capital guardrails.
