Filing Released Lang Actions
(訂正）「2026年３月期 決算短信〔日本基準〕（連結）」の一部訂正について
Regulatory Filings Classification · 80% confidence The document is a notice of correction (‘訂正’) to the previously disclosed 2026/3 earnings summary (‘決算短信’), not the initial earnings release itself. It serves to amend specific financial data points rather than present a standalone new quarterly report. There is no dedicated “earnings correction” category, so this amendment is best classified under the general regulatory filings fallback.

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly cites '金融商品取引法第24条の５の２第１項' (Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as an officer certification confirming the accuracy of a semi-annual report. 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.

半期報告書－第86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). As it is a formal, comprehensive financial report for a period shorter than a full fiscal year, it falls under the 'Interim / Quarterly Report' category. 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 is submitted to the Kinki Local Finance Bureau Director. Section 1 explicitly states the reason for filing: the resolutions passed at the company's 85th Annual General Meeting (AGM) held on June 25, 2025. Section 2 details the resolutions, including the approval of the surplus appropriation (dividend) and the election of seven directors. This content—reporting the results of a shareholder meeting—directly corresponds to the definition of Declaration of Voting Results & Voting Rights Announcements (DVA). Although it relates to the AGM, the specific focus is on the *results* of the votes, not the presentation materials (AGM-R) or the proxy solicitation (PSI). Given the explicit reporting of voting outcomes, DVA is the most precise classification.

内部統制報告書－第85期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document explicitly states its title and purpose in the header: "【提出書類】 内部統制報告書" (Document Submitted: Internal Control Report) and cites 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 structure and content—discussing the framework, scope, criteria, and conclusion regarding internal controls over financial reporting (ICFR)—is characteristic of a Japanese statutory filing related to internal controls. In the provided classification scheme, the closest match for a standalone report detailing internal control assessment results, especially one tied to financial reporting integrity, is 'Audit Report / Information' (AR), as it covers internal/regulatory stress tests and applied accounting principles, which aligns conceptually with the ICFR assessment, although 'AR' is not a perfect fit for the Japanese '内部統制報告書'. However, given the options, and recognizing this is a formal, comprehensive report on internal controls (not just an announcement), 'AR' is the most appropriate category among the choices that cover formal reporting/auditing functions, distinct from an Annual Report (10-K) or an Earnings Release (ER). Since this is a comprehensive report and not an announcement of a report, RPA/RNS is ruled out. It is a formal report on internal controls, which falls under the umbrella of assurance/audit-related documentation.

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly references the Financial Instruments and Exchange Act (金融商品取引法). It serves as an officer certification confirming 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 should be classified as Regulatory Filings (RNS), even if they reference a specific report type.
