（訂正）「2026年3月期決算説明会資料」の一部訂正について
Investor Presentation Classification · 95% confidence The document is a comprehensive “決算説明会資料” (earnings presentation) including detailed financial summaries, forecasts, segment analyses, charts, and strategic outlook. It is more than a brief announcement or link to a report and clearly constitutes the actual investor presentation material used to explain results and guidance. Therefore, it fits the Investor Presentation category.

2026年3月期決算説明会資料
Investor Presentation Classification · 97% confidence The document is titled “2026年3月期決算説明会” (FY2026 earnings presentation) and consists of slides with consolidated P&L, balance sheet, cash flows, segment analysis, FY2027 forecasts, and mid-term plan progress.

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 of Japan. 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, even if they reference a report (in this case, a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第78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 under the Financial Instruments and Exchange Act of Japan.

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 resolutions were passed at the 77th Annual General Meeting (定時株主総会) held on June 20, 2025, pursuant to the Financial Instruments and Exchange Act. Section 2 details the resolutions, which include the approval of dividends (剰余金の処分の件) and the election of directors and an auditor (取締役選任の件, 監査役選任の件). Crucially, the document provides the detailed voting results (賛成, 反対, 棄権) for each resolution. This content—reporting the official results of shareholder votes from a general meeting—perfectly matches the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). The document length is short (2485 chars), but its purpose is to report the *results* of the meeting, not just announce that a report is forthcoming, thus distinguishing it from RPA or RNS.
