[기재정정]특수관계인으로부터주식의취득
Transaction in Own Shares Classification · 85% confidence The document is a corrected disclosure (정정신고) regarding the acquisition of shares from related parties by SK Corp (a company buying its own (subsidiary) shares). This falls squarely under the category of a transaction in own shares (share repurchase or acquisition). Thus, the appropriate filing category is Transaction in Own Shares (POS).

[기재정정]특수관계인과의내부거래
Regulatory Filings Classification · 82% confidence The document is a correction (“정정신고”) to a previously filed related-party transaction disclosure (“특수관계인과의 내부거래”). It does not present an AGM presentation, annual or interim report, earnings release, capital update, governance code, or any other specialized filing. It is a regulatory disclosure amendment under local rules, so it falls into the fallback category for miscellaneous regulatory announcements.
