役員の異動及び組織再編に関するお知らせ
Board/Management Information Classification · 87% confidence The document is a Japanese notice titled “Notice concerning changes in directors and organizational restructuring” with details on director appointments, resignations, and department reorganization. This fits the definition of “Board/Management Information” (announcements of changes in the company's board or senior management).

当社株式等の大規模買付行為に関する対応策（買収への対応方針）の継続について
Governance Information Classification · 85% confidence The document is a public notice dated May 21, 2026 by Midac Holdings outlining the board’s decision to continue its takeover‐defense “large‐scale share acquisition response plan” (the so-called poison pill). It contains detailed governance policies, board and committee structures, and procedures for countermeasures to unsolicited bids. This is not a financial report (e.g., earnings, interim report) nor a merger announcement, but rather a governance policy update. It therefore falls under the Governance Information category (CGR).

確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (確認書) filed under Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act. It serves as an officer certification regarding the accuracy of a previously filed 'Correction to the Semi-Annual Report'. Per the 'Certification Rule', documents that are primarily officer certifications or attestations, even if they reference a financial report, should be classified as Regulatory Filings (RNS) rather than the report itself. The document length is also short (1482 characters), confirming it is a regulatory filing/certification rather than a full financial report. H1 2025

Interim / Quarterly Report Classification · 100% confidence The document is a 'Correction of Semi-Annual Report' (訂正半期報告書) filed under the Financial Instruments and Exchange Act. It contains detailed financial statements, including the balance sheet and income statement for the interim period ending September 30, 2025. As it provides comprehensive financial data and analysis for a period shorter than a full fiscal year, it is classified as an Interim/Quarterly Report. H1 2026

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly references '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, even if they reference a report (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself, as they do not contain the actual financial statements.
