2026年3月期決算説明会資料
Investor Presentation Classification · 85% confidence The document is the slide deck for the "2026年3月期決算説明会" (full‐year financial results briefing) including detailed financial results, segment breakdowns, forecasts for 2027, and mid‐term strategy. It is not merely an earnings summary (ER), nor is it the formal statutory annual report (10-K) or a bare management report (MDA). Rather, it is clearly a presentation prepared for investors and analysts (決算説明会資料). Therefore it maps to Investor Presentation (Code: IP).

確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, Article 24-5-2, Paragraph 1. It serves as an officer certification confirming the accuracy of the contents of a 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23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 under the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow statement for the interim period (April 1, 2025, to September 30, 2025). This fits the definition of an Interim/Quarterly Report (IR) as it provides substantive financial data and analysis for a period shorter than a full fiscal year. H1 2026

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 submitted because resolutions were passed at the "第22回定時株主総会" (22nd Annual General Meeting) held on June 27, 2025. Section 2 details the resolutions, including the approval of the dividend (剰余金の処分の件) and the election of directors (取締役選任の件), along with the voting results. This content—reporting the outcomes of an AGM—is characteristic of an AGM Results Report. While the filing itself is a regulatory disclosure (臨時報告書), the core subject matter is the declaration of voting results from a general meeting. Therefore, the most specific classification is Declaration of Voting Results & Voting Rights Announcements (DVA). The document length is moderate, but the content is a direct report of results, not an announcement of a future report.

内部統制報告書－第22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 references the legal basis as "金融商品取引法第24条の４の４第１項" (Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act). This specific filing requirement in Japan mandates the submission of an Internal Control Report concerning financial reporting. The content discusses the framework, scope, criteria, and conclusion regarding the assessment of internal controls over financial reporting as of the fiscal year-end (March 31, 2025). This directly corresponds to the requirements for an Audit Report/Information filing, specifically focusing on internal controls assessment, which aligns best with the 'AR' (Audit Report / Information) category among the provided options, as it is a formal report on internal control effectiveness, distinct from a full Annual Report (10-K) or a simple Earnings Release (ER).

According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference a specific report type.
