Filing Released Lang Actions
대규모기업집단현황공시[연1회공시및1/4분기용(대표회사)]
Regulatory Filings Classification · 85% confidence The document is a statutory “기업집단현황공시” (annual group status disclosure) filed by SK Co., Ltd. to Korean regulators, listing its affiliates, business details, employee counts, etc. It contains no financial statements or management narrative and appears solely as a compliance/regulatory announcement. Thus it does not represent an annual or interim report, proxy, earnings release, or other specific filing type, but rather a general regulatory filing. Accordingly, it should be classified as Regulatory Filings (RNS).

대규모기업집단현황공시[연1회(동일인용)]
Regulatory Filings Classification · 85% confidence The document is a large-scale enterprise group status disclosure (“대규모기업집단현황공시”) required under Korean regulations, detailing affiliate companies and shareholdings. It is not an annual or quarterly financial report, management change, earnings release, or any other narrowly defined filing type. It is a compliance/regulatory disclosure of affiliate status, fitting none of the specific categories, so it falls under the fallback “Regulatory Filings” category.

[기재정정]타법인주식및출자증권취득결정(자회사의 주요경영사항)
Regulatory Filings Classification · 20% confidence The document is a Korean statutory disclosure (“주요경영사항신고” / “정정신고”) detailing a portfolio rebalancing share‐swap transaction by SK On, including acquisition terms, financial metrics, and corrections. It is not a financial report (10‐K/IR), earnings release, management change, dividend notice, or proxy statement. It is a routine regulatory announcement of a corporate event that does not fit other narrow categories, so it defaults to a general regulatory filing.

[기재정정]타법인주식및출자증권처분결정(자회사의 주요경영사항)
Regulatory Filings Classification · 75% confidence The document is a Korean regulatory ‘정정신고(보고)’ correction filing detailing the company’s decision to dispose of third‐party shareholdings (“타법인 주식 및 출자증권 처분결정”), including financial tables, board resolutions, and material disclosures. It is neither an annual/quarterly report nor an earnings release, financing update, or ESG report. It is a standalone regulatory disclosure of a corporate action that does not fit a more specific category, so it falls under the fallback “Regulatory Filings” (RNS).
2026-05-28 Korean
[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.
