Filing Released Lang Actions
（訂正）「役員人事に関するお知らせ」の一部訂正に関するお知らせ
Board/Management Information Classification · 85% confidence The document is a short correction notice (“訂正”) for a previously released announcement concerning executive personnel changes (“役員人事に関するお知らせ”). This clearly pertains to board/management information. It is not the original appointment announcement itself but still falls under Management/Board Information (MANG), not a full report or other category.

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, Article 24-5-2, Paragraph 1. It serves as an officer certification regarding the accuracy of a 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 a semi-annual report.

半期報告書－第18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 by Sumiseki Holdings, Inc. in Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow statement for the interim period (April 1, 2025, to September 30, 2025). This fits the definition of an Interim/Quarterly Report (IR) as it provides substantive financial data and analysis for a period shorter than a full fiscal year. H1 2026

臨時報告書
Regulatory Filings Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director on June 30, 2025. The filing reason explicitly states that the company is submitting this report based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because an event occurred that significantly impacts the company's financial condition, operating results, and cash flow situation. The content details receiving a dividend (剰余金の配当) from a consolidated subsidiary, which is a significant financial event requiring timely disclosure under Japanese regulations. This type of mandatory, event-driven disclosure that doesn't fit neatly into standard periodic reports (like 10-K or IR) or specific announcements (like DIV or CAP) is best classified as a general Regulatory Filing (RNS) in this context, as it is a specific regulatory filing form (Fifth Form No. 3 under the Cabinet Office Ordinance on Disclosure of Corporate Information). Given the options, RNS serves as the most appropriate catch-all for mandatory, non-standard regulatory disclosures.

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 because resolutions were passed at the company's "第17回定時株主総会" (17th Annual General Meeting) held on June 27, 2025. Section 2 details the resolutions, which concern the election of directors and alternate auditors, and provides the voting results (votes for, against, abstentions). This content directly relates to the official results from a shareholder meeting. Therefore, the most appropriate classification is Declaration of Voting Results & Voting Rights Announcements (DVA).
