Regulatory Filings
2026-04-30 Korean
[기재정정]단일판매ㆍ공급계약체결(자율공시)
Regulatory Filings Classification · 1% confidence The document is a Korean voluntary disclosure (“자율공시”) for the signing and subsequent amendment of a single large sales and supply contract (단일판매·공급계약 체결). It details the contract amount, counterparties, and contract terms. This is neither a financial report (10-K, IR), earnings release, dividend notice, management change, M&A, nor financing announcement. It is a standard regulatory announcement about a contract, so it falls into the fallback category of general regulatory filings (RNS).

[기재정정]단일판매ㆍ공급계약체결(자율공시)
Regulatory Filings Classification · 1% confidence The document is a Korean timely disclosure (자율공시) announcing the execution (and subsequent correction) of a single sales and supply contract. It details contract amounts, counterparty, and dates, without covering financial results, management changes, financing, dividends, or ESG matters. There is no fitting category for a pure contract disclosure, so under the fallback rule it belongs to “Regulatory Filings” (RNS).
2026-03-26 Korean
정기주주총회결과
Declaration of Voting Results & Voting Rights Announcements Classification · 1% confidence The document is titled “정기주주총회 결과” (Regular Shareholders’ Meeting Results) and lists the resolutions, vote counts/percentages for each agenda item (approval of financial statements, director appointments, changes to articles of incorporation, etc.). This matches the definition of “Declaration of Voting Results & Voting Rights Announcements” (Code: DVA). It is not a presentation (AGM-R) or the full annual report (10-K), but specifically the official voting results of a general meeting.
2026-03-26 Korean
사외이사의선임ㆍ해임또는중도퇴임에관한신고
Board/Management Information Classification · 1% confidence The document is a formal filing to the Financial Supervisory Service and Korea Exchange detailing the appointment, dismissal, and mid-term retirement of outside directors (“사외이사의 선임ㆍ해임 또는 중도퇴임에 관한 신고”). It specifies changes in board composition and individual outside director appointments, which clearly falls under an announcement of changes in the company's board of directors. This matches the Board/Management Information category.
2026-03-26 Korean
대표이사변경
Board/Management Information Classification · 1% confidence The document is a corporate announcement detailing a change in the company’s 대표이사 (CEO/representative director), including names before and after, dates of board resolution and change, attendance at the board meeting, and related notices. This clearly corresponds to a Board/Management Information filing regarding senior management changes. Therefore, it should be classified as MANG.
