「内部統制システムの基本方針 」の一部改定に関するお知らせ
Governance Information Classification · 90% confidence The document is a TDnet-style disclosure announcing a partial revision of the company’s “Basic Policy on Internal Control Systems,” detailing the firm’s governance framework, internal control and compliance structures. It does not present financial results, voting outcomes, share transactions, or a published report attachment but rather updates internal governance rules. This best fits “Governance Information” (CGR).

（訂正・数値データ訂正） 「2026 年 3 月期 決算短信[日本基準]（連結）」の一部訂正について
Earnings Release Classification · 85% confidence The document is titled “2026年3月期 決算短信日本基準"の一部訂正について" and contains corrected consolidated financial highlights (P/L, B/S, cash flow, segment and per-share data) for the March 2026 quarter. It is a correction to the company’s quarterly earnings release (決算短信), not a full annual report or merely a publication notice. This aligns with the "Earnings Release" (ER) category for initial announcements of periodical financial results. FY 2026

（訂正） 「2025 年度（2026 年3 月期）決算説明会」および「2025 年度（2026 年3 月期）決算説明会（ノート付）」の 一部訂正について
Investor Presentation Classification · 80% confidence The document is a correction notice for the detailed “2025年度(2026年3月期)決算説明会” materials, showing updated balance‐sheet slides and supplementary data. It is not a simple press release (ER) nor the formal annual/quarterly financial report itself (10-K/IR), but rather the detailed presentation slides for the financial results briefing. Hence it falls under Investor Presentation (IP).

2025年度(2026年3月期) 決算説明会 (ノート付)

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 and CFO regarding the accuracy of the company's 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.
