Filing Released Lang Actions
주요사항보고서(중요한자산양수도결정(기타))
Regulatory Filings Classification · 85% confidence The document is a Korean ‘주요사항보고서’ (Material Event Report) filed under the Capital Markets Act describing a major asset acquisition (important asset transfer decision). It is not an annual or interim financial report, earnings release, dividend notice, proxy statement, or investor presentation, nor is it a simple announcement of an upcoming report. It contains full transaction details of equipment, patents, trademarks, payment schedules, counterparties, and external valuations. No other category (e.g., M&A Activity in our taxonomy is limited to mergers/takeover bids) precisely covers a Korean material-assets-transfer regulatory filing, so it falls into the fallback “Regulatory Filings” category.

분기보고서 (2026.03)
Interim / Quarterly Report Classification · 94% confidence The document is titled “분기보고서 (제21기) 2026년 01월 01일 – 2026년 03월 31일” (Quarterly Report for Q1 2026) filed with the Korean Financial Services Commission and Korea Exchange. It contains comprehensive interim financial statements (revenue breakdown, production capacity, risk management policies), business overviews, changes in capital, and other substantive quarterly data. This aligns with an Interim / Quarterly Report. Q1 2026

[기재정정]최대주주변경을수반하는주식양수도계약체결
Major Shareholding Notification Classification · 75% confidence The document is a public disclosure of a stock purchase and sale agreement that will result in a change of the company’s largest shareholder. It details the parties, share quantities, prices, dates, and the resulting ownership percentages—i.e., informing the market of a significant shareholding change above reporting thresholds. This matches the “Major Shareholding Notification” category rather than a full report, earnings release, or share issuance. Therefore, it is classified as MRQ.

단일판매ㆍ공급계약체결
Regulatory Filings Classification · 75% confidence The document is a public announcement of a single sale and supply contract (mass spectrometer) with a customer (Kangwon National University). It details contract amount, period, parties, and terms. This is a routine regulatory disclosure of a material contract rather than a financial report, management change, dividend notice, or financing event. It does not fit specialized categories (e.g., 10-K, IR, ER, M&A), so it falls into the fallback “Regulatory Filings” category.
2026-04-22 Korean
기타시장안내 (상장폐지 관련 이의신청서 접수 및 개선기간 부여)
Regulatory Filings Classification · 70% confidence The document is a Korean stock exchange notice (“기타시장안내”) concerning the submission of an objection to a proposed delisting and the granting of an improvement period. It is not the actual delisting decision but a regulatory announcement by the exchange about the listing status and compliance deadlines. This is a general regulatory filing rather than the execution of a full delisting or a company report. Therefore, it fits the “Regulatory Filings” fallback category (RNS).
2026-04-13 Korean
주권매매거래정지기간변경 (개선기간 부여)
Regulatory Filings Classification · 85% confidence The document is a brief regulatory notice concerning the change of the trading suspension period for a listed security under KOSDAQ listing rules. It cites specific market rules and provides details of the period change, without presenting financial statements, management commentary, or investor presentation materials. It is not an AGM material, report filing, or capital change announcement but rather a routine regulatory announcement. Thus, it falls under the fallback category of a general regulatory filing.
