[기재정정]최대주주변경을수반하는주식담보제공계약체결
Capital/Financing Update Classification · 95% confidence The document is a detailed announcement regarding a stock pledge contract involving a change in the largest shareholder. It includes specifics about the stock collateral, debt amounts, contract dates, and related parties. The content focuses on financing arrangements and changes in capital structure related to stock collateral agreements. There is no indication that this is a full annual or quarterly report, audit report, or earnings release. The document is not a simple announcement of a report publication but a substantive update on financing activities. Therefore, the document fits best under the category of Capital/Financing Update (CAP).

기업가치제고계획(자율공시)
Regulatory Filings Classification · 65% confidence The document is a voluntary regulatory disclosure (“자율공시”) of the company’s detailed corporate value enhancement plan with specific strategic objectives and shareholder return policies. It is not an earnings release, dividend notice, proxy statement, or any standard financial report category. It is the actual plan text, not a notice of report publication. Thus it falls under General Regulatory Filings (RNS) as a miscellaneous regulatory announcement.
