確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly states it is 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 should be classified as Regulatory Filings (RNS), even if they reference a specific report type.

半期報告書－第124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 Seiko Corporation (靜甲株式会社) in accordance with the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow analysis for the interim period ending September 30, 2025. As it is a formal interim financial report containing substantive financial data, it is classified as an Interim/Quarterly Report. H1 2026

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 because resolutions were passed at the "第123回定時株主総会" (123rd Annual General Meeting) held on June 25, 2025. Section 2 details the resolutions passed, including dividend approval, amendments to the articles of association, and the election/re-election of directors and auditors. The content is a formal report detailing the results of a shareholder meeting. This strongly aligns with the purpose of reporting the outcomes of an Annual General Meeting (AGM). While it reports the results, the primary nature of the filing is the official record of the AGM proceedings and outcomes, making AGM-R the most appropriate classification, rather than just a general regulatory filing (RNS) or a proxy statement (PSI) which precedes the meeting.

内部統制報告書－第123期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the header and within the main table structure. It references 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), which mandates the filing of an Internal Control Report by listed companies in Japan. Section 1 discusses the framework for internal controls over financial reporting, Section 2 details the scope and procedures for the evaluation, and Section 3 states the evaluation result (deemed effective). This content perfectly matches the description of an Audit Report / Information (AR), which covers internal or regulatory stress tests and applied accounting principles, although in this specific context, it is the Japanese equivalent of the Sarbanes-Oxley Section 404 report on internal controls over financial reporting. Given the provided definitions, 'AR' (Audit Report / Information) is the closest fit for a formal report detailing internal control effectiveness and audit standards application, distinct from a full Annual Report (10-K) or a simple Earnings Release (ER).
