[기재정정]타인에대한채무보증결정
Capital/Financing Update Classification · 75% confidence The document is a corporate announcement concerning the decision to guarantee a third party’s debt (debt guarantee decision) and a corresponding correction of that announcement. This is a financing support activity rather than a share transaction or board change. Under the provided taxonomy, such updates on the company's financing activities—including guarantees—best fit Capital/Financing Update (CAP).

분기보고서 (2026.03)
Interim / Quarterly Report Classification · 92% confidence The document is titled “분기보고서” covering the 72nd fiscal period Q1 (2026.01.01–2026.03.31) and contains full financial statements, business segments, detailed notes, and management analysis. It is a comprehensive quarterly report, not just an announcement or earnings highlight. This matches the definition of an Interim/Quarterly Report (Code: IR). Q1 2026

투자판단관련주요경영사항(자회사의 주요경영사항)
Regulatory Filings Classification · 80% confidence The document is a Korean stock exchange disclosure titled “투자판단 관련 주요경영사항” (Major Management Matters Related to Investment Decisions). It notifies the market that a subsidiary (Hyosung Heavy Industries) has been selected as the contractor for a redevelopment project. It contains no financial statements or report attachments, nor is it an earnings release, board change, share transaction, or capital update. This type of compliance/regulatory announcement does not fit a more specific category, so it defaults to the general Regulatory Filings (RNS) category.

타인에대한채무보증결정(자회사의 주요경영사항)
Capital/Financing Update Classification · 78% confidence The document is a formal disclosure of a debt guarantee decision by Hyosung T&C for its affiliate Hyosung Japan Co., Ltd. It details the creditor, guarantee amount, period, board resolution date, and related financial metrics. This is not an earnings release or management change, nor a dividend, capital change in share capital, or share repurchase. Instead, it reports a financing-related decision (debt guarantee) by the company. Hence, it falls under Capital/Financing Update (CAP).

기업설명회(IR)개최(안내공시)
Regulatory Filings Classification · 80% confidence The document is a short regulatory announcement in Korean providing logistics for an upcoming corporate investor relations presentation (IR) – date, time, location, participants, purpose, and reference to materials on the website. It is not the presentation deck itself, nor a detailed financial report, nor a proxy or voting result. It therefore falls under the general “Regulatory Filings” catch-all category (RNS).
