業績予想の修正に関するお知らせ
Earnings Release Classification · 89% confidence The document is a securities notice titled “業績予想の修正に関するお知らせ” (Notice of Revision to Earnings Forecast) issued by a listed company. It provides revised consolidated and non-consolidated earnings forecasts (sales, operating profit, net profit, EPS) for the full fiscal year ending March 2026, comparing prior and updated forecasts and explaining reasons for the changes. This constitutes a financial performance update (earnings guidance revision) rather than a full annual/interim report or a regulatory certification. It aligns with our Earnings Release category (ER) for announcements of periodical financial results or forecast updates. FY 2026

確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act of Japan. It serves as an officer certification regarding the accuracy of the semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report type (in this case, a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第75期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Taisei Oncho Co., Ltd. under the Financial Instruments and Exchange Act of Japan. It contains detailed financial statements, including the balance sheet and income statement for the interim period (April 1, 2025, to September 30, 2025). As it is a comprehensive financial report for a period shorter than a full fiscal year containing substantive financial data, it is classified as an Interim/Quarterly Report (IR). H1 2026

有価証券届出書（組込方式）
Share Issue/Capital Change Classification · 95% confidence The document is a '有価証券届出書' (Securities Registration Statement) filed with the Kanto Local Finance Bureau by Taisei Oncho Co., Ltd. This document is a formal regulatory filing required under the Financial Instruments and Exchange Act of Japan for the issuance of new securities (in this case, shares for an executive stock compensation plan). It contains detailed information about the offering, the issuer, and incorporates previous reports by reference. It does not fit into the specific categories of Annual Reports, Earnings Releases, or Proxy Statements, and is a standard regulatory filing for capital issuance.

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report) and explicitly states in Section 1 that it is being submitted based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were passed at the Annual General Meeting (AGM) held on June 24, 2025. Section 2 details the resolutions, including dividend approval (剰余金処分の件) and the election of directors (取締役選任の件), along with the voting results (賛成、反対及び棄権の数). This content—reporting the results of a shareholder meeting—perfectly matches the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to the AGM, the core purpose is reporting the *results* of the vote, not providing the meeting materials (AGM-R) or proxy information (PSI).

内部統制報告書－第74期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly cites the legal basis as "金融商品取引法第24条の４の４第１項" (Financial Instruments and Exchange Act Article 24-4-4, Paragraph 1). This structure and content—detailing the framework, scope, criteria, and conclusion regarding the effectiveness of internal controls over financial reporting as of a specific fiscal year-end (March 31, 2025)—is characteristic of a mandatory Japanese regulatory filing related to internal controls. While the definitions provided do not have a specific code for the Japanese 'Internal Control Report' (which often accompanies the 10-K equivalent or is filed separately), the closest functional equivalent among the provided codes that deals with formal, comprehensive reporting on internal controls and financial integrity is the Annual Report (10-K) or Audit Report (AR). However, since this is a specific Japanese regulatory filing focused purely on internal controls, and it is a comprehensive report (not just an announcement), it is most closely aligned with the comprehensive reporting requirements. Given the options, and recognizing that this is a formal, annual assessment of controls, it shares characteristics with both 10-K (as it relates to financial reporting integrity) and AR (as it is a formal report on controls). Since the document is the report itself and not an announcement of a report, and it is a comprehensive annual assessment, I will classify it based on its comprehensive nature. In the context of US filings, the internal control report is a key part of the 10-K. If a specific code for this Japanese filing type isn't available, the closest fit for a comprehensive annual financial integrity report is 10-K, although AR is also plausible. Given the explicit mention of '財務報告に係る内部統制' (Internal Control over Financial Reporting), which is a core component of the 10-K filing in the US context, 10-K is the most appropriate classification among the choices for a comprehensive annual report on financial integrity controls. The document length is substantial, confirming it is the report itself, not an announcement (RPA/RNS).
