Filing Released Lang Actions
소속부변경
Regulatory Filings Classification · 95% confidence The document is a brief announcement about a change in the company's department affiliation from '중견기업부' (Mid-sized Enterprise Division) to '벤처기업부' (Venture Enterprise Division) due to meeting venture regular requirements. It is very short (232 characters) and does not contain financial data, regulatory certifications, or detailed reports. It is an operational update rather than a financial or governance report. This type of announcement does not fit into categories like Annual Report, Earnings Release, or Management Reports. It is best classified as a Regulatory Filing (RNS), which is the fallback category for miscellaneous regulatory announcements that do not fit other specific categories.

주요사항보고서(제3자의전환사채매수선택권행사)
Capital/Financing Update Classification · 95% confidence The document is titled '주요사항보고서(제3자의전환사채매수선택권행사)' which translates to 'Major Event Report (Exercise of Third Party Convertible Bond Purchase Option)'. It is addressed to the Financial Services Commission and dated April 30, 2026. The content details the exercise of purchase options on convertible bonds, including terms, dates, amounts, and involved parties. This is a regulatory disclosure about a capital/financing event involving convertible bonds and call options. It is not a full financial report, earnings release, or management discussion. The document is about a financing update related to convertible bonds and call options. Therefore, the appropriate classification is Capital/Financing Update (CAP). The document length is about 4800 characters, sufficient to contain substantive details about the financing event, not just an announcement of a report publication or a short notice.

[기재정정]유형자산취득결정(자율공시)(종속회사의주요경영사항)
Regulatory Filings Classification · 82% confidence The document is a self-disclosure (“자율공시”) of a decision by a subsidiary to acquire tangible assets (real estate). It is an operational transaction announcement, not an earnings release, financing update, management change, dividend notice, or any other predefined category. Therefore it falls into the fallback “Regulatory Filings” category (RNS).
