新中期経営計画の策定に関するお知らせ
Investor Presentation Classification · 90% confidence The document is an announcement of the company’s new medium-term (3-year) management plan, including strategic objectives, key initiatives, and financial targets for 2026-2028. It is not a notice of a vote, dividend, or regulatory certification, nor is it an actual financial statement (10-K/IR) or simple press release of earnings. Instead, it provides a detailed investor-oriented presentation of strategy, outlook, and targets, consistent with an Investor Presentation (IP).

2026年３月期　決算短信〔日本基準〕(連結)
Earnings Release Classification · 90% confidence The document is a Japanese “決算短信” released on May 13, which is the preliminary earnings release summarizing the full‐year (fiscal March 2026) consolidated financial results. It includes key highlights (sales, profits, forecasts), summary financial statements (P&L, BS, cash flows) and segment commentary, but explicitly notes it is not audited. This matches an Earnings Release, not a full Annual Report (10-K) or interim/quarterly statutory report. Accordingly, it is classified as ER. FY 2026

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. It serves as an officer certification by the CEO of Showa Manufacturing Co., Ltd. regarding the accuracy of the semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report type, should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第104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. It contains comprehensive financial statements, including the balance sheet, income statement, and management's analysis of financial results for the interim period (April 1, 2025, to September 30, 2025). As it is a formal, comprehensive financial report for a period shorter than a full fiscal year, it falls under the 'Interim / Quarterly Report' category. H1 2025

内部統制報告書－第103期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly references the legal basis as "金融商品取引法第24条の４の４第１項" (Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act). It discusses the framework, scope, criteria date (March 31, 2025), and evaluation procedures for internal controls over financial reporting, concluding that the internal controls are effective. This structure and content precisely match the requirements for an Internal Control Report, which is typically filed alongside the Annual Report (10-K) or as a standalone compliance document in Japan. Given the specific focus on internal control assessment, the most appropriate classification among the provided options is 'Audit Report / Information' (AR), as it covers internal/regulatory stress tests and applied accounting principles/reports, although '10-K' is often the context where this is found. However, since this is a specific internal control assessment document, and 'AR' is defined as 'Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports)', it fits better than 10-K if it's not the full annual report package. The Japanese term '内部統制報告書' directly translates to an Internal Control Report, which falls under the scope of regulatory compliance reporting related to financial integrity, aligning closely with the spirit of AR.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (738 characters) and contains a header section indicating it is a "確認書" (Confirmation Document) submitted to the Fukuoka Local Finance Bureau Director, referencing Article 24-4-2, Paragraph 1 of the Financial Instruments and Exchange Act. The main body explicitly states that the Representative Director confirms the contents of the company's 103rd period Annual Securities Report (有価証券報告書) for the fiscal year ending March 31, 2025, are appropriate. This document is a formal confirmation statement regarding the accuracy of a previously filed Annual Report (10-K equivalent in Japan). Since it is a short confirmation document related to the accuracy of a major filing, and not the full report itself, it fits best under the general category for regulatory filings or specific confirmation documents. Given the options, and the nature of confirming the accuracy of a major filing (like a 10-K), it is a specific regulatory confirmation. However, none of the codes perfectly match a 'Confirmation of Accuracy' document. The closest fit for a document confirming the accuracy of a major filing, which is not the filing itself, is often categorized under general regulatory filings (RNS) or, if it were a specific type of audit/review confirmation, AR. Since it is a direct confirmation by management regarding the *Annual Securities Report* (which is the Japanese equivalent of a 10-K), and it is a short, formal declaration, it is most likely a specific regulatory filing that doesn't fit the main categories. Given the structure, it is a formal regulatory submission. I will classify it as RNS (Regulatory Filings) as it is a specific, short regulatory confirmation document that doesn't match the definitions for 10-K, AR, or ER, and it is not an announcement of a report release (RPA).
