기업가치제고계획(자율공시)
Regulatory Filings Classification · 65% confidence The document is a voluntary disclosure (‘자율공시’) of YMC’s Corporate Value Enhancement Plan, containing strategic goals, projections and legal references.

[기재정정]주식매수선택권부여에관한신고
Share Issue/Capital Change Classification · 78% confidence The document is a Korean regulatory filing titled “주식매수선택권 부여에 관한 신고” (Report on granting stock options) including corrected figures from a prior submission. It is an announcement of a corporate grant of stock purchase rights (options), which constitutes a potential future issuance of new shares and thus falls under share issue/capital change. This is not a director’s personal transaction report, nor a full financial report, and it clearly announces terms of a stock-option grant. Under our categories, this best maps to Share Issue/Capital Change (SHA).
