F1Quarterly and full-year results summaries (tanshin) published in English3/5

An English '[Summary] Consolidated Financial Results' is posted every quarter (FY2018 onward in the English IR Library's year selector) and filed on TDnet at the same minute as the Japanese (Q1 FY2026 7 Aug 2026 15:30; FY2025 13 May 2026 15:30). Every period on the Japanese cycle. But each one is cut down: Q1 FY2026 is 7 pp against 11 in Japanese, FY2025 10 pp. The English has the summary pages and the statements (balance sheet, income and comprehensive income, and at year end changes in net assets and cash flows), but nothing for the Japanese 1. 経営成績等の概況 and no notes (segment information, going concern, cash flow).

F2English results summary is a full translation, not an excerpt3/5

Q1 FY2026 against the Japanese 2027年3月期 第1四半期決算短信 (11 pp). The English (7 pp) carries the summary pages and the statements only.

F5Segment revenue and profit disclosed in English, consistent definitions3/5

Segment sales are in English every quarter in the 'Supplementary Financial Information' (10 pp, consolidated and non-consolidated net sales by segment and by product), but segment profit is not: the English tanshin has no segment note and the supplementary data give consolidated operating profit only. The Japanese tanshin carries the segment note. Sales without profit, so 3. Source document →

F6Multi-year financial data file (Excel or CSV) downloadable in English0/5

The English Financial Highlights page (annual and quarterly tabs) shows Highcharts graphs and HTML tables for FY2021-FY2025 (sales, profit, financial position, cash flow, per-share). We rendered it and searched it for any download: no Excel or CSV link. HTML tables do not count.

The '(in Japanese only)' label is on the Sumitomo Mitsui Trust materials portal.
