Findings by question
F1Quarterly and full-year results summaries (tanshin) published in English5/5
Summary of Consolidated Financial Results for the three months ended 30 June 2026 under IFRS, in English, 6 August 2026 - 20 pages, 81,000 characters, with the segment note and the cash flow statement. Source document →
F2English results summary is a full translation, not an excerpt5/5
The English Summary of Consolidated Financial Results for Q1 FY2026 (three months to 30 June 2026, IFRS; listed 6 August 2026, the same day as the Japanese) runs 19 pages against 19 in the Japanese tanshin, with the same contents: summary of results, financial position and forecasts; condensed interim statements of income and comprehensive income, financial position, changes in equity and cash flows; the notes (going concern, segment information, changes in equity, subsequent events); and the consolidated reference section (revenue of major products, R&D, capex and depreciation, FX). The full-year English edition (12 May 2026) is 27 pages against 24. A whole translation, so 5. Source document →
F3Financial statements including notes available in English5/5
The Q1 FY2026 English tanshin carries the full condensed interim statements (income and comprehensive income, financial position, changes in equity, cash flows) with their notes, and the full-year edition the full consolidated statements and notes; the English Annual Securities Report (177 pages) carries the audited statements and notes for the year to March 2026. Full statements and notes for the latest period, so 5. Source document →
F4Annual securities report available in English in any form4/5
The Annual Securities Report for the year ended 31 March 2026 in English - the current year, 178 pages, carrying the company overview, business overview, risk factors, management's analysis, governance and the financial statements. One thing is missing: the text stops at Part II and the independent auditor's report is not translated, so the English reader gets the numbers without the opinion on them. Source document →
F5Segment revenue and profit disclosed in English, consistent definitions5/5
Single-segment company, and it says so in English: 'Segment information is omitted because the Santen Group is a single segment' (FY2025 tanshin notes). In its place the English Data Book gives, every quarter, revenue by region (Japan, China, Asia, EMEA, location basis) and contribution profit by region, with the definition of contribution profit stated in a note (regional revenue less cost of sales and expenses related to revenue generation), plus the full-year forecast by region; the deck repeats the regional growth with and without FX. Scored on the regional breakdown, which is complete, defined and held every period, so 5. Source document →
F6Multi-year financial data file (Excel or CSV) downloadable in English0/5
No downloadable data file. The English Data Book is a 4-page PDF each quarter (14 pages at the full year); the Latest IR Documents, Data Book, Consolidated Performance and Presentation Materials pages link PDFs only, with no .xlsx/.xls/.csv anywhere in them (link scan, 19 Oct 2026). The integrated report's financial highlights are PDF too.
F7Guidance disclosed in English with the basis explained5/5
The FY2026 forecast (year to March 2027) is in the English tanshin with its basis: exchange-rate assumptions (USD 155, EUR 180 yen), the market view behind it (drug price revisions at the high end of the 1% level, market-expansion re-pricing, generic entry) and, in the Data Book, the forecast by region. Q1 states 'Earnings forecast: no change from forecast announced on May 12'. Two or more assumption types with the revision status explained, so 5. Source document →
F8English financial disclosure current to the latest Japanese filing period5/5
English Q1 results for the year ending March 2027 published 6 August 2026, the same period as the Japanese filing. Source document →
S1Medium-term management plan in English with numerical targets5/5
FY2025-2029 Medium-Term Management Plan in English: the plan deck (52 pages, the same page count as the Japanese) and its transcript, listed on 21 May 2025 alongside the Japanese, and a Medium-Term Management Plan page with the FY2029 targets: revenue 400 billion yen, core operating profit 80 billion yen (EBITDA 90 billion), ROE over 14%, double-digit EPS growth (160 yen or more), minimum dividend of 38 yen. Current, quantified, as complete as the Japanese, so 5. Source document →
S2IR presentations published in English5/5
Presentation for Q1 FY2026 in English with a transcript of the briefing published alongside it, and the same pairing for every quarter back through FY2025 plus a separate product development meeting with its own transcript. Source document →
S3English equity-story or investment-highlights page5/5
Santen Report 2026 (English, published 7 October 2026) has a dedicated 'Santen at a Glance' spread (p.7) with quantified strengths: products reaching patients in over 60 countries/regions, about 400 million units a year, 49% overseas sales ratio, No. 1 market share in Japan and Asia (IQVIA), 3,968 employees, 26.2 billion yen of R&D. A dedicated at-a-glance section with numbers, so 5. Source document →
S4Growth drivers identified and quantified in English5/5
The English MTP deck names the drivers and puts numbers on them: overseas sales ratio from 44% to 58% by FY2029, EMEA sales of 100 billion yen, Asia 65 billion and China 65 billion yen in FY2029, new markets in myopia and ptosis, with the pipeline and capacity plans. Named drivers with numbers attached, so 5. Source document →
S5Results-briefing transcripts or Q&A published in English4/5
An English transcript is published for every briefing the Japanese side transcribes (Q1-Q3 and full year FY2025, Q1 FY2026, the product development meeting, the MTP briefing), the same day as the Japanese. The Q2 and Q3 English transcripts carry the full Q&A; the full-year FY2025 and Q1 FY2026 English transcripts carry the Q&A only as a summary ('Question & Answer (Summary Version)'), where the Japanese transcripts give it in full (Q1: 19 Japanese pages against 14 English). Every period, but a Q&A summary where the Japanese has the full exchange, so 4. Source document →
S6Integrated or annual report available in English4/5
Integrated Report 2025 in English, 7.5MB, whole or chapter by chapter with a separate financial statements file - but it is for the year ended 31 March 2025. One edition behind as at 1 October 2026. Source document →
S7Progress against the previous plan, including misses, explained in English5/5
The FY2025-2029 plan opens with a 'Review of performance targets for previous Medium-Term Management Plan' (p.7): previous FY2025 targets against FY2024 outcomes - revenue 280.0 vs 300.0 billion yen, core OP 56.0 vs 59.4 billion yen (20% margin), core ROE 13% vs 15%, core EPS growth over 10% vs 23%, shareholder returns - each marked 'Achieved', with the structural reforms behind them and a review of key initiatives (p.8). Targets set against actuals with the explanation, so 5. Source document →
G1Corporate governance report available in English5/5
The Corporate Governance Report in English, with the Basic Policy on Corporate Governance, the Basic Policy on Internal Control and a summary of the board effectiveness evaluation alongside it. Source document →
G2Director biographies in English with tenure, expertise and independence5/5
The English notice of the 114th AGM (18 pages) gives every director candidate - the whole board stands each year - with career history, years served as director (e.g. nine years, two years), reasons for nomination, and independence designations for each outside director. All three elements for every director, so 5. Source document →
G3Board skills matrix published in English5/5
The English Corporate Governance page carries the 'Skill Matrix of Directors and Corporate Auditors (as of June 23, 2026)', the current board after the June AGM. Current matrix in English, so 5. Source document →
G4Executive remuneration structure and its performance linkage explained in English5/5
The English Business Report for the 114th AGM sets out the structure (basic compensation, annual bonus, performance share units, restricted stock units, restricted stock) and weights for every performance-linked element (p.23). Annual bonus: revenue 25%, core operating profit 50%, ROE 25% for the CEO; revenue 20%, core operating profit 40%, ROE 20% and individual evaluation 20% for the other directors (Schedule 3). Performance share units: relative TSR 70% and strategic targets, ESG included, 30% (Schedule 4). It gives the FY2025 results against the bonus targets and the amounts by pay type (basic 301 million yen, bonus 111 million, PSU 116 million, RSU 17 million, RS 87 million yen for directors). Weights re-read 21 Oct 2026. Structure, KPIs, weights and amounts, so 5. Source document →
G5AGM notice in English with sufficient lead time to vote4/5
Electronic provision from 25 May 2026 for the 114th AGM on 23 June - 29 days, the longest lead time across both batches - with the notice (19 pages, fourteen candidate-profile entries), the Business Report and Financial Statements, and the Audit Report all published separately in English. Re-checked 23 Oct 2026 (G5 voting-site sweep, after the independent audit): the voting website named in the English notice, evote.tr.mufg.jp (Mitsubishi UFJ Trust and Banking), is in Japanese only, with no English option, as for ESPEC (6859) and Nitto Boseki (3110). Every proposal in English, but a Japanese-only voting route, so 4. Source document →
G6Shareholder vote results disclosed in English2/5
A Resolution Notice is published in English on the day of the meeting, reporting what was resolved. No votes, no abstentions, no approval ratios anywhere in it. Source document →
G7Cross-shareholdings in English with reduction schedule and rationale3/5
The English Corporate Governance Report (updated 26 June 2026) states the policy on strategic shareholdings (held only where they strengthen business relationships, verified issue by issue by the board at least annually, within a maximum total amount) and the year's progress (two listed issues sold in FY2025, reducing the balance sheet amount by 517 million yen); the English Annual Securities Report gives the number of issues and carrying amounts. There is no reduction target or schedule, only a cap on the total. Policy, numbers and progress without a target, so 3. Source document →
O1English IR section reachable within two clicks of the English homepage5/5
From the English homepage (santen.com/en) the 'Investor Relations' panel links straight to the IR top (santen.com/en/ir): one click. The header 'Investor Relations' item opens a dropdown whose first entry is the IR top. One click, so 5. Source document →
O2English document links resolve to English documents5/5
Fourteen English document links sampled across types, all English documents: FY2025 and Q1 FY2025 tanshin, FY2025 deck, Q3 FY2025 transcript, FY2025 Data Book, Integrated Report 2025, 114th AGM voting result and resolution notice, 113th AGM notice, Basic Policy on Corporate Governance, MTP FY2023-2025 deck, MTP 2018-2020 deck, pipeline, Sustainability Report 2025. None Japanese, so 5. Source document →
O3English IR archive free of dead links5/5
The same fourteen links all opened (the oldest a 2018 MTP deck), none dead. So 5. Source document →
O4English IR pages render without blank JavaScript failures5/5
Rendered: IR top, Latest IR Documents, Presentation Materials, Stock Information, Materials for the General Meeting, Stock Chart (an external Nomura quote link behind a notice), IR Calendar, Dividends and IR Contact all render their content; no empty lists or blank widgets. So 5. Source document →
O5Single page listing all English IR documents by date and type4/5
'Latest IR Documents' is one page laying out tanshin, presentation, transcript, Data Book, integrated report, securities report and pipeline by fiscal year and quarter, typed by row. AGM materials, the governance report and timely disclosures sit on other pages (Materials for the General Meeting, Corporate Governance, IR News). One dated page, not every type, so 4. Source document →
O6English archive genuinely populated, not an unverifiable shell5/5
Several years across types: presentations and transcripts back through FY2023 (with a Capital Markets Day), tanshin back to FY2024, AGM materials back to the 111th meeting, medium-term plans back to 2003-2005, integrated reports by year. So 5. Source document →
O7Named English IR contact published4/5
The English IR top (www.santen.com/en/ir) ends with a full-width 'IR Contact' panel. It leads to the IR Contact page ('Please use the submission forms below for inquiries concerning investor relations'), which links the IR FAQ and an 'IR inquiries (Investor only)' form. That form (santen.com/en/contact/m_form_2, titled 'IR Inquiries') is IR-only, with no category picker. Guillaume Sakuma, Global Head of Investor Relations, +81-6-7664-8621, is also named in the results summary. Re-checked 17 Oct 2026: the earlier 3 rested on the superseded rule that a 4 needs a named person on the site. Under the current bands a dedicated IR route linked straight from the IR top is 4, with or without a name, so the score moves from 3 to 4. Source document →
R1Earnings materials published in English simultaneously with Japanese5/5
By the listing dates the English tanshin and deck come out the same day as the Japanese every period read: Q1 FY2026 6 Aug 2026, FY2025 12 May 2026, Q3 5 Feb 2026, Q2 6 Nov 2025, Q1 7 Aug 2025, on both sides' pages. The English and Japanese deck PDFs share creation dates (Q1 FY2026 both 7 Aug; FY2025 both 17 Jun after a re-upload); the English transcripts likewise match the Japanese (Q1 both 10 Aug, FY both 19 May). Same day every period, so 5. Source document →
R2Median lag in days between Japanese and English statutory publication5/5
Japanese / English: Q1 FY2026 tanshin 6 Aug / 6 Aug = 0; FY2025 tanshin 12 May / 12 May = 0; 114th AGM notice: the statutory electronic-provision commencement date stated in the English notice is 25 May 2026 and the English PDF was created that day (the Japanese PDF was finalised 20 May) = 0, or at most 5 days; Corporate Governance Report last updated 26 Jun 2026 on both = 0; Annual Securities Report filed 18 Jun 2026, English PDF created 16 Sep 2026 = 90. Median 0 days either way, so 5. Source document →
R3Timely disclosures published in English5/5
Twelve months of the Japanese IR news (Oct 2025 - Oct 2026) against the English: every timely disclosure has a same-day English version - results (Feb, May, Aug), director nominations (19 Mar), treasury-share disposals (3 Sep, 30 Sep), the AVS transfer (2 Oct), the subsidiary bankruptcy petition (16 Oct) - and the governance report (26 Jun). The only Japanese-only item is a 13 Oct product price-revision notice to customers, not a timely disclosure. All, same day, so 5. Source document →
R4English disclosure free of machine-translation accuracy disclaimers5/5
No machine-translation notice on the rendered English pages (homepage, IR top, Latest IR Documents, governance, terms of use) or in the English documents read (tanshin, deck, AGM notice, securities report). So 5. Source document →
R5English version stated as authoritative, not subordinate to Japanese1/5
'Translation for reference purpose only' on the securities report; on the resolution notice, 'provided for your convenience only. In case of any discrepancy ... the latter shall prevail'; the AGM notice adds that it is a translation of only a part. Source document →

2025 share buyback: 19.8 million shares
Buyback · Completed · Board authorization 13 May 2025
Santen completed the 19.8 million-share ceiling by 5 November 2025 for ¥31.896bn, below the ¥35bn spending ceiling. The contemporaneous cancellation notice set a future date; this case does not independently verify cancellation completion or attribute later ROE to this purchase.
Timeline and sources (3 steps)
- 13 May 2025Board authorized repurchase Up to 19,800,000 shares (5.8%) and ¥35bn over 22 May–5 November 2025; the issuer cited shareholder returns and capital efficiency. Santen Announces Share Buyback
- 21 May 2025Five-year capital policy published The FY2025–29 plan put growth investment first, with opportunistic repurchases linked to share price and surplus cash; FY2029 ROE above 14% is a group target, not a buyback-specific return promise. Santen Announces FY2025–2029 Medium-Term Management Plan
- 5 November 2025 · announced 6 November 2025Purchase period completed The issuer reported cumulative purchases of 19,800,000 shares for ¥31,896,010,850, then resolved to cancel 19,800,000 shares on a scheduled 28 November date. Santen Announces Completion of Share Buyback · Santen Announces Cancellation of Treasury Shares
What management said it would do
The 13 May 2025 board decision authorized up to 19.8m shares and ¥35bn through 5 November. Santen cited shareholder returns and capital efficiency; its 21 May plan prioritized growth investment and allowed opportunistic buybacks from surplus cash.
From the company’s own disclosure · Santen Announces Share Buyback · Santen Announces FY2025–2029 Medium-Term Management Plan
What it actually did, and when
The issuer reported on 6 November that 19.8m shares had been purchased for ¥31,896,010,850 through 5 November. A separate board decision scheduled cancellation of 19.8m shares for 28 November; this record has not verified a later completion notice.
From the company’s own disclosure · Santen Announces Completion of Share Buyback · Santen Announces Cancellation of Treasury Shares
What it disclosed about the economics
The plan frames buybacks as a use of surplus cash when investment opportunities and share price warrant it, against an FY2029 group ROE goal above 14%. The authorization quantifies capital used but does not publish an individual buyback return hurdle or expected EPS lift.
Partly disclosed — a gap remains · Santen Announces FY2025–2029 Medium-Term Management Plan · Santen Announces Share Buyback
What has happened since
The share ceiling was fully used; actual spending was ¥3.104bn below the maximum. That verifies program execution, not an attributable improvement in economic returns. FY2029 ROE is not yet due and cancellation completion remains to be checked.
Partly disclosed — a gap remains · Santen Announces Share Buyback · Santen Announces Completion of Share Buyback · Santen Announces FY2025–2029 Medium-Term Management Plan · Santen Announces Cancellation of Treasury Shares
The question this leaves open
Investor question: What portion of later ROE/EPS change comes from operating gains rather than the lower share count, and how were repurchases weighed against pipeline investment? IR preparation: provide a dated share-count/cancellation and normalized earnings bridge.
