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. It serves as an officer certification regarding the accuracy of a previously filed 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 like an interim/semi-annual report.

半期報告書－第97期(2025/06/01－2026/05/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Semi-Annual Report' (半期報告書) for JDC Corporation, covering the period from June 1, 2025, to November 30, 2025. It includes detailed financial statements (balance sheets, income statements, etc.), management analysis, and audit review information. This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. H1 2026

確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act of Japan. It serves as a formal certification by the CEO and CFO regarding the accuracy of the company's Annual Securities Report (Yuuka Shouken Houkokusho). Since this is a regulatory filing required by law to accompany financial reporting but does not constitute the full Annual Report (10-K) or an earnings release, it falls under the general regulatory filing category.

有価証券報告書－第96期(2024/06/01－2025/05/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of a 10-K annual report. It contains a formal header identifying the document type, the fiscal year (96th period), the reporting period (June 1, 2024, to May 31, 2025), and the filing date (August 22, 2025). The presence of extensive XBRL-like metadata tags and the formal structure confirm it is the full annual financial report. FY 2025

臨時報告書
Regulatory Filings Classification · 100% confidence The document is explicitly titled "【提出書類】 臨時報告書" (Filing Document: Extraordinary Report) and references compliance with the Financial Instruments and Exchange Act (金融商品取引法) and related regulations (企業内容等の開示に関する内閣府令). The content details a change in a specific subsidiary (特定子会社) due to an investment exceeding 10% of the company's capital, which is a material event requiring immediate disclosure. In the context of Japanese regulatory filings, an Extraordinary Report (臨時報告書) is typically classified under the general category for significant, non-periodic disclosures. Given the provided options, this type of material event disclosure, which is not a standard periodic report (like 10-K or IR) or a specific announcement (like DIV or DIRS), fits best under the general 'Regulatory Filings' category (RNS) or potentially a specific category if one existed for material changes. Since the document is a formal regulatory filing reporting a material change (acquisition/change of control over a subsidiary), and 'RNS' is defined as 'General regulatory announcements and fallback category for miscellaneous filings that do not neatly fit into other specific categories,' RNS is the most appropriate classification. It is not an Earnings Release (ER), Interim Report (IR), or a specific announcement like Director's Dealing (DIRS) or Capital Change (CAP).
