임원ㆍ주요주주특정증권등소유상황보고서
Major Shareholding Notification Classification · 90% confidence The document is a Korean “임원ㆍ주요주주 특정증권등 소유상황보고서,” i.e. a mandatory filing reporting ownership and changes in specific securities by an insider/major shareholder (in this case a >10% shareholder). It details share counts, ratios, and changes as of a reporting date. This aligns with a Major Shareholding Notification (MRQ), not a general regulatory announcement or director certification.

Capital/Financing Update Classification · 75% confidence The document is a corrected “투자설명서” (investment prospectus) filed on 2026-06-04 amending the previously submitted prospectus of 2026-05-12.
