Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. It specifically references the 'Semi-Annual Report' (Hankishokokusho) for the period ending September 30, 2025, and confirms the accuracy of its contents. Since this is a regulatory filing required by law to accompany financial reports and does not fit into the specific categories of the reports themselves, it falls under the general regulatory filing category.

半期報告書－第99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 with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It contains detailed financial statements, management analysis, and business status for the interim period (April 1, 2025, to September 30, 2025). 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

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 filed because the resolutions from the Annual General Meeting (AGM) held on June 25, 2025, have been finalized, citing relevant Japanese financial regulations (FSA Order Article 19, Paragraph 2, Item 9-2). Section 2 details the resolutions passed, including dividend approval (剰余金処分の件) and the election of directors (取締役選任の件), along with the vote counts (賛成数, 反対数, 棄権数). This content—reporting the results of a general meeting—perfectly matches the definition for Declaration of Voting Results & Voting Rights Announcements (DVA). Although it relates to the AGM, the document's primary function is reporting the *results* of the vote, not presenting the proxy materials (PSI) or the general meeting presentation itself (AGM-R). Given the specific content detailing vote outcomes, DVA is the most accurate classification.

訂正意見表明報告書
M&A Activity Classification · 100% confidence The document is titled with Japanese characters that translate to 'Opinion Statement Report' (意見表明報告書) and is filed with the Kanto Local Finance Bureau Director (関東財務局長) on June 17, 2025. The content explicitly discusses a Tender Offer (公開買付け) by Hulic Co., Ltd. (ヒューリック株式会社) for Koken Boring Machine Co., Ltd. (鉱研工業株式会社) shares, detailing the offer price, rationale, and the target company's board resolution to support the tender offer. This type of document, where the target company states its opinion on a tender offer, is known as a Target Company's Position Statement or Opinion Statement, which corresponds to the Proxy Solicitation & Information Statement category (PSI) in the provided definitions, as it solicits shareholder action (tendering shares) based on management's recommendation. Although it is a formal regulatory filing, PSI is more specific than the general RNS fallback.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (588 characters) and appears to be a confirmation document ('確認書') related to the appropriateness of the contents of a securities report ('有価証券報告書') for the 98th fiscal period (ending March 31, 2025). It is signed by the Representative Director and President, confirming the report's compliance with financial instruments laws. This structure—a brief confirmation document referencing a major filing (Securities Report, which is equivalent to a 10-K in the US context) rather than being the full report itself—suggests it is a supplementary filing or a specific regulatory confirmation. Given the options, this document confirms the accuracy of a major annual filing (Securities Report/10-K). However, since it is a confirmation document ('確認書') and not the full 10-K, and it doesn't fit perfectly into AR (Audit Report) or ER (Earnings Release), it is most likely a specific regulatory filing or confirmation. In the context of Japanese filings, this type of confirmation often accompanies the main filing. Since it is a confirmation of the *Securities Report* (Annual Report), and it is not the report itself, it is best classified as a general Regulatory Filing (RNS) or potentially an Audit Report (AR) if it were related to the audit opinion, but here it is a management confirmation. Given the lack of a specific code for 'Securities Report Confirmation,' and its brevity, RNS (Regulatory Filings) is the most appropriate fallback for a specific, non-standard regulatory confirmation document.

有価証券報告書－第98期(2024/04/01－2025/03/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). The header explicitly states '有価証券報告書' (Securities Report) and provides the fiscal year period (2024-04-01 to 2025-03-31), company details, and filing date. It is a comprehensive annual financial disclosure filed with the Kanto Local Finance Bureau, fitting the definition of an Annual Report. FY 2025
