Report Publication Announcement Classification · 100% confidence The document text contains the header "第２四半期報告書" (Second Quarter Report) and explicitly mentions the period covered: "第81期中（自 2024年４月１日 至 2024年９月30日）". It also references compliance with the Financial Instruments and Exchange Act ("金融商品取引法"). A comprehensive report covering a period shorter than a year (half-year/quarterly) is classified as an Interim/Quarterly Report (IR). Although the document structure resembles a certification or cover page for the report, the core subject matter is the content of the semi-annual financial report itself, making 'IR' the most appropriate classification over a simple 'RPA' or 'RNS', especially given the explicit mention of the financial period and the nature of the content confirming its adequacy.

半期報告書－第81期(2024/04/01－2025/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '第２四半期報告書' (Second Quarter Report) for Sekisui Kasei Co., Ltd., covering the period from April 1, 2024, to September 30, 2024. It contains detailed financial statements, management analysis (MDA), and corporate information required by the Financial Instruments and Exchange Act of Japan. As it is a comprehensive financial report for a period shorter than a full fiscal year, it falls under the 'Interim / Quarterly Report' category. H1 2025

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and explicitly states in Section 1 that it is being filed because resolutions were passed at the "当社第80回定時株主総会" (The 80th Annual General Meeting of Shareholders) held on June 21, 2024. Section 2 details the resolutions, including dividend approval and the election/re-election of directors and auditors, along with the voting results (votes for, against, abstentions, and approval percentages). This content directly relates to the official results of a shareholder meeting. The most specific category for official results from shareholder votes is 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to the AGM, the primary focus is reporting the *results* of the votes, not the presentation materials (AGM-R) or the proxy solicitation (PSI).

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly references '金融商品取引法第24条の４の２第１項' (Article 24-4-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as a formal certification by the CEO regarding the accuracy of the company's Annual Securities Report (有価証券報告書). According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report, should be classified as Regulatory Filings (RNS).

内部統制報告書－第80期(2023/04/01－2024/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly states its basis in Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項). It details the framework, scope, criteria (using the standard issued by the Financial Accounting Standards Board), and the conclusion that internal controls over financial reporting are effective as of the fiscal year-end (March 31, 2024). This document is a formal, required report concerning internal controls over financial reporting, which aligns best with the Audit Report / Information category (AR), as it is a specific report on internal controls rather than the full annual financial performance (10-K) or a general announcement.

有価証券報告書－第80期(2023/04/01－2024/03/31)

It contains comprehensive financial statements, business descriptions, and governance information for the fiscal year ending March 31, 2024. The document is clearly the full annual report rather than an announcement or summary. FY 2024
