Report Publication Announcement Classification · 1% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act, specifically confirming the accuracy of the contents of a Semi-Annual Report (Hankishokokusho) for the period ending September 30, 2025. Since this is a regulatory filing required by law to accompany financial reports and does not fit into the specific categories of financial statements or earnings releases, it is classified as a Regulatory Filing (RNS).

半期報告書－第44期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed by '株式会社免疫生物研究所' (Immuno-Biological Laboratories Co., Ltd.) for the period ending September 30, 2025. It contains detailed financial statements, including the balance sheet and income statement, and is prepared in accordance with Japanese GAAP. As it is a comprehensive financial report for a period shorter than a full fiscal year containing substantive financial data, it is classified as an Interim/Quarterly Report. H1 2026

臨時報告書
AGM Information Classification · 1% confidence The document is titled '臨時報告書' (Extraordinary Report) and explicitly states in Section 1 that it is being submitted because the resolutions from the '定時株主総会' (Annual General Meeting - AGM) held on June 26, 2025, have been finalized, citing relevant Japanese financial regulations (FSA Order Article 19, Paragraph 2, Item 9-2). Section 2 details the resolutions, specifically the election of five directors, and provides the vote counts (For, Against, Abstain) for each candidate. This content directly relates to the official results of a shareholder vote following an AGM. Therefore, the most appropriate classification is Declaration of Voting Results & Voting Rights Announcements (DVA).

内部統制報告書－第43期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document contains a header section explicitly stating the filing type as "内部統制報告書" (Internal Control Report) and 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). The content discusses the framework, scope, criteria, and conclusion regarding the assessment of internal controls over financial reporting ("財務報告に係る内部統制"). This directly corresponds to the requirements for an internal control report, which is typically filed alongside the Annual Report (10-K) but is a distinct regulatory document focusing solely on internal controls. Given the specific nature of the content (Internal Control Report) and the lack of a direct match in the provided codes, the closest conceptual fit among the options that deals with formal, comprehensive reporting and regulatory compliance is the Annual Report (10-K), although 'AR' (Audit Report/Information) is also a possibility if the document is interpreted as a standalone assurance report. However, since this is a management assertion on internal controls, and not a standard Audit Report, and it is not the full 10-K, it is a specialized regulatory filing. In the context of US SEC filings, the Internal Control Report is a required component of the 10-K. Since there is no specific code for an 'Internal Control Report', and it is a formal, comprehensive report on financial integrity, it is most closely related to the comprehensive annual reporting structure. Given the options, and recognizing this is a formal regulatory filing about financial integrity, I will classify it as 'AR' (Audit Report / Information) as it relates to assurance/verification of financial processes, or 'RNS' as a fallback. Given the detailed nature and formal structure, it is more substantial than a simple RNS. Since 'AR' covers 'applied accounting principles, and results of internal or regulatory stress tests', this fits the theme of internal control assessment better than other options. However, if we strictly adhere to the definitions, this is a management assertion, not an external audit report. Therefore, the most appropriate fallback for a formal, non-standard regulatory document is RNS, or if we must choose a financial reporting category, 10-K is too broad if it's just this section. Let's re-evaluate: The document is a formal Japanese regulatory filing (Internal Control Report). Since there is no specific code for this, and it is a formal report, I will use the fallback 'RNS' (General regulatory announcements/miscellaneous filings).

確認書
Audit Report / Information Classification · 1% confidence The document is extremely short (592 characters) and contains a header structure typical of Japanese regulatory filings, specifically mentioning "【提出書類】確認書" (Document Submitted: Confirmation Document) and referencing the Financial Instruments and Exchange Act ("金融商品取引法"). The core content confirms that the Representative Director has verified the appropriateness of the contents of the company's Annual Securities Report ("有価証券報告書") for the fiscal year ending March 31, 2025. This document is a certification or confirmation related to the filing of a major report (like a 10-K equivalent), rather than the report itself. Since it is a specific confirmation document related to the annual filing, and it doesn't fit perfectly into the standard US definitions (10-K, AR), it is best classified as a general Regulatory Filing (RNS) or potentially an Audit Report/Information (AR) if the confirmation is part of the audit process. Given the explicit mention of confirming the 'Annual Securities Report' (which is the Japanese equivalent of a 10-K), and the document being a short confirmation rather than the full report, it falls under a general regulatory filing category. RNS is the most appropriate fallback for specific, non-standard regulatory confirmations that aren't explicitly defined elsewhere, although AR is a possibility if this confirmation is considered part of the audit/assurance process. Given the context of confirming the *Annual Securities Report*, and the lack of a specific code for 'Confirmation of Annual Report Filing', RNS is the safest general regulatory classification.
