確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. It serves as a formal certification by the CEO regarding the accuracy of the Annual Securities Report (Yuuka Shouken Houkokusho). Since it is a regulatory filing required by law to accompany financial reporting but does not constitute the financial report itself, and given the specific nature of the filing, it falls under the general regulatory filing category.

有価証券報告書－第24期(2024/10/01－2025/09/30)
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 identifies it as '有価証券報告書' (Securities Report) filed under the Financial Instruments and Exchange Act, covering a full fiscal year (2024-10-01 to 2025-09-30). It contains extensive XBRL tagging and financial data, confirming it is the full annual report rather than an announcement. FY 2025

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, where the CEO certifies 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 (in this case, 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24期(2024/10/01－2025/09/30)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed by SK-Electronics CO., LTD. with the Kinki Finance Bureau in Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and management analysis for the interim period ending March 31, 2025. As it is a formal, comprehensive financial report for a period shorter than a full fiscal year, it is classified as an Interim/Quarterly Report. H1 2025

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (609 characters) and contains a header structure typical of Japanese regulatory filings, specifically mentioning a '確認書' (Confirmation document) submitted to the '近畿財務局長' (Director of Kinki Local Finance Bureau) based on Article 24-4-2, Paragraph 4 of the Financial Instruments and Exchange Act. The core content confirms that the President/CEO has verified the accuracy of the '有価証券報告書' (Securities Report, equivalent to a 10-K) for the period ending September 30, 2024. This document is a certification/confirmation related to the accuracy of a previously filed annual report, not the full annual report itself. Since it is a specific confirmation document related to the accuracy of a major filing, and it is not a standard 10-K, AR, or ER, it falls best under the general 'Regulatory Filings' (RNS) category as a specific regulatory confirmation/attestation, or potentially an Audit Report/Information (AR) if interpreted as a certification of the audit, but RNS is safer for miscellaneous regulatory confirmations. Given the context of confirming the accuracy of a Securities Report (which is the 10-K equivalent), and its brevity suggesting it's an accompanying document rather than the main report, RNS is the most appropriate fallback for this specific certification.

It includes XBRL metadata and detailed financial disclosure information, confirming it is the full annual report rather than an announcement or summary. FY 2024
