臨時報告書
Regulatory Filings Classification · 85% confidence The document is a Japanese "臨時報告書" (Extraordinary Report) filed under the Financial Instruments and Exchange Act disclosing a change in a specified subsidiary and recognition of a special loss. It is a mandatory timely disclosure announcement rather than the report of financial results itself or an interim/annual report. This type of filing falls under general regulatory announcements and compliance documents. Therefore, it should be classified as Regulatory Filings (RNS).

確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, specifically certifying 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 specific report type (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.

半期報告書－第48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) for Osaka Steel Co., Ltd., covering the period from April 1, 2025, to September 30, 2025. It contains detailed financial statements, including the balance sheet, and is filed under the Financial Instruments and Exchange Act. As it is a comprehensive financial report for a period shorter than a full fiscal year containing actual financial statements, it is classified as an Interim/Quarterly Report. H1 2026

臨時報告書
AGM Information Classification · 100% confidence The document is titled '臨時報告書' (Extraordinary Report) and is submitted to the Kanto Local Finance Bureau ('関東財務局長'). Section 1 explicitly states the reason for filing is that resolutions were passed at the Annual General Meeting ('定時株主総会') held on June 25, 2025, pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act. Section 2 details the resolutions, including dividend amounts and the election/re-election of directors and auditors, followed by the voting results (votes for, against, abstentions). This structure perfectly matches the definition of reporting the results of a shareholder meeting, which is specifically covered by the 'Declaration of Voting Results & Voting Rights Announcements' (DVA) category, as it reports the outcome of the AGM resolutions.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (618 characters) and contains a table structure typical of a cover page for a Japanese regulatory filing. Key elements include: "【提出書類】確認書" (Filing Document: Confirmation Letter), "【根拠条文】金融商品取引法第24条の４の２第１項" (Basis Article: Article 24-4-2, Paragraph 1 of the Financial Instruments and Exchange Act), and a confirmation statement by the CEO regarding the appropriateness of the "有価証券報告書" (Annual Securities Report, equivalent to 10-K) for the fiscal year ending March 31, 2025. Since this document is a 'Confirmation Letter' (確認書) related to the Annual Securities Report, and not the full report itself, it functions as a certification or supplementary filing. Given the options, this specific certification/confirmation document does not fit perfectly into 10-K (the report itself) or ER (Earnings Release). It is a regulatory document confirming compliance related to the annual filing. However, based on the definitions, it is a specific type of regulatory confirmation rather than a general announcement (RPA/RNS). Since it is a formal confirmation related to the annual filing process, and not a general announcement of a report release, it is best classified as a Regulatory Filing (RNS) as a catch-all for specific compliance confirmations that don't match other categories, or potentially a specialized Audit/Compliance report (AR). Given the context of confirming the *Annual Securities Report* (10-K), and that it is a formal, required certification, RNS is the most appropriate fallback for specific compliance documents not explicitly listed, though AR (Audit Report/Information) is a possibility if this confirmation is considered part of the audit assurance process. Given the explicit reference to the Financial Instruments and Exchange Act certification, RNS (General regulatory announcements/fallback) is the safest classification for this specific confirmation document type.
