Filing Released Lang Actions
[기재정정]감자결정(종속회사의주요경영사항)
Share Issue/Capital Change Classification · 86% confidence The document is a regulatory disclosure of a capital reduction (‘감자 결정’) for a subsidiary, detailing shares before/after, ratios, dates and related changes. This is a formal announcement of a share capital change rather than a full financial report, earnings release or management commentary. Therefore it falls under the “Share Issue/Capital Change” category.

[기재정정]타인에대한채무보증결정(자회사의 주요경영사항)
Regulatory Filings Classification · 80% confidence The document is a regulatory announcement under the Korean Capital Markets Act detailing the company’s decision to guarantee third-party debt (an affiliate loan guarantee). It is not an earnings release, financial report, proxy, or dividend notice. It provides detailed disclosure of a guarantee (investment decision) rather than actual financial data in a report. It therefore falls into the generic Regulatory Filings (RNS) category.

[기재정정]타인에대한채무보증결정(자회사의 주요경영사항)
Regulatory Filings Classification · 20% confidence The document is a Korean regulatory correction filing (‘정정신고’) reporting revised details of a debt guarantee decision (‘타인에대한채무보증결정’) by the company’s subsidiary. It does not present full financial statements, nor is it an earnings release, investor presentation, or capital raising announcement. Instead, it is a detailed compliance disclosure under capital markets law. It therefore falls into the general Regulatory Filings category (RNS) as a catch-all for regulatory disclosures that do not match more specific categories.

[기재정정]유형자산처분결정(종속회사의주요경영사항)
Regulatory Filings Classification · 30% confidence The document is a Korean regulatory correction disclosure regarding BlueOval SK, LLC’s decision to dispose of tangible assets. It provides details of the asset disposal decision, corrected values, and relevant subsidiary information. It does not contain financial statements or constitute a formal report (e.g., Annual Report, Interim Report), nor is it a call transcript, earnings release, or financing announcement. It is a public regulatory filing without fitting other more specific categories, so it falls under the general Regulatory Filings category.

Such miscellaneous compliance filings that do not fit other specific categories fall under Regulatory Filings (RNS).
