Annual Report Classification · 95% confidence The document is titled '有価証券報告書（通常方式）', which translates to 'Securities Report (normal form)' filed under the Financial Instruments and Exchange Act, with a submission date of June 24, 2026. The report covers the 71st term from April 1, 2025, to March 31, 2026, indicating a full fiscal year. This matches the definition of an Annual Report (10-K), which is a comprehensive yearly report covering full financial performance and company activities. The document contains confirmation by the CEO regarding the report’s proper disclosure rather than simply announcing the filing or providing attachments, indicating it is the report itself or an integral component of it rather than a publication announcement or regulatory filing certification alone. Therefore, the best classification is Annual Report (10-K). The confidence is high given the official nature, content, and time coverage. FY 2026

有価証券報告書－第71期(2025/04/01－2026/03/31)
Annual Report Classification · 100% confidence The document is titled '有価証券報告書（通常方式）' which translates to 'Securities Report (Regular Form)' in Japanese. It is submitted to the Kinki Finance Bureau under the Financial Instruments and Exchange Act Article 24 paragraph 1, for the fiscal year ending March 31, 2026 (71st fiscal period from April 1, 2025 to March 31, 2026). The content includes extensive financial data such as consolidated financial indicators, shareholder equity, net assets, and income figures over multiple years. The document length is very large (over 129,000 characters), indicating this is a full report, not a brief announcement or a certification letter. It contains comprehensive financial performance information and business overview data. Given the Japanese regulatory nomenclature, the '有価証券報告書' corresponds to the official annual report similar to the US 10-K filings which cover full financial performance and company activities for the fiscal year. Therefore, this document is classified as an Annual Report (10-K). FY 2026

支配株主等に関する事項について
Major Shareholding Notification Classification · 95% confidence The document is a formal notification regarding controlling shareholders related to the company Sansei Co., Ltd. It provides data about share ownership percentages of a related company, including a table summarizing the ownership stakes. The document does not include financial statements, quarterly or annual financial data, nor is it a discussion of results or management commentary. It is primarily an announcement of shareholding details, specifically relating to controlling shareholders and their stakes. Given the shareholding threshold percentages and the focus on major shareholders, this fits the definition of 'Major Shareholding Notification' (MRQ). The document length is short and focused, further supporting a notification rather than a full report or detailed regulatory filing. There is no indication of a voting result, management change, or dividend announcement, so those categories are excluded.

当社株式等の大規模買付行為に関する対応策（買収への対応方針）継続に関するお知らせ
Regulatory Filings Classification · 80% confidence The document is a Japanese timely disclosure by Sansei Co., Ltd. announcing the continuation of its large-scale share acquisition defense measures (“poison pill”) and detailing the full takeover defense plan. It is not a financial report (10-K, IR, ER), not an AGM presentation, not a management change, not earnings or dividend notice, nor a call transcript. It is an operational/regulatory update filed under disclosure obligations, fitting the catch-all category for miscellaneous regulatory compliance announcements. Therefore it is best classified as a Regulatory Filing (RNS).

代表取締役の異動（追加）及び役員人事に関するお知らせ
Board/Management Information Classification · 24% confidence The document is an official Japanese stock exchange announcement detailing changes in representative directors (追加 of a new representative director), board of directors, external auditors, and the new management lineup following the upcoming annual shareholders meeting. It outlines personnel appointments, promotions, reappointments, and retirements of senior management and board members.

Notice of Dividend Amount Classification · 92% confidence The document is a formal notice of the board’s resolution on dividend distribution (“剰余金の配当に関するお知らせ”), specifying the record date, per-share dividend (ordinary and special), total amount, effective date, and rationale. This matches the ‘Notice of Dividend Amount’ category.
