確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act, specifically accompanying a Second Quarter Report (Interim Report). While it references the interim report, the document itself is a formal regulatory filing confirming the accuracy of the financial statements for the period ending August 31, 2025. Since it is a specific regulatory requirement for Japanese listed companies to file this confirmation alongside their interim reports, and it does not fit into the 'Interim Report' category itself (which would be the financial statements), it is best classified as a Regulatory Filing.

半期報告書－第27期(2025/03/01－2026/02/28)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) for the company '株式会社メディアドゥ' (MEDIA DO Co., Ltd.) for the period ending August 31, 2025. It contains detailed financial statements, management analysis (MDA), and corporate information as required by the Financial Instruments and Exchange Act of Japan. This is a comprehensive interim financial report, not an announcement or a summary, and therefore fits the definition of an Interim/Quarterly Report (IR). 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 filed pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were made at the Annual General Meeting (AGM) held on May 29, 2025. Section 2 details the resolutions, specifically the election of directors and an auditor. This structure—a formal filing reporting the results of a shareholder meeting—aligns perfectly with the definition of reporting voting results from a general meeting. The appropriate code is DVA (Declaration of Voting Results & Voting Rights Announcements). Although it relates to an AGM, the document's purpose is reporting the *results* of the votes, not presenting AGM materials (AGM-R) or soliciting proxies (PSI).

内部統制報告書－第26期(2024/03/01－2025/02/28)
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" (Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act). This structure and content—assessing the effectiveness of internal controls over financial reporting as of a specific fiscal year-end (2025年２月28日)—is characteristic of the Japanese equivalent of the Sarbanes-Oxley Section 404 report, which is a mandatory annual filing related to financial reporting integrity. While the US equivalent is often associated with the 10-K, this specific document type in Japan is a standalone report focusing solely on internal controls. Given the provided definitions, this document is a comprehensive report detailing internal control structure and assessment results, which aligns best with the scope of an Audit Report / Information (AR), as it deals with the assurance and structure surrounding financial reporting, distinct from a full Annual Report (10-K) or a simple Earnings Release (ER). It is a formal, detailed report on financial control assurance.
