Filing Released Lang Actions
기타시장안내 (상장폐지 관련)
Delisting Announcement Classification · 90% confidence The document is a market notice in Korean titled “기타시장안내(상장폐지 관련)” (“Other Market Notice (Delisting Related)”). It informs shareholders that the company received a delisting notice due to a disclaimer of audit opinion for fiscal 2025 and explains the objection period. This is clearly a delisting announcement rather than an annual report, audit report, or earnings release. Therefore, it fits the Delisting Announcement category.

주권매매거래정지기간변경 (상장폐지 사유 발생)
Delisting Announcement Classification · 85% confidence The document is an official notice regarding a change in the trading suspension period for ordinary shares of Astar Co. due to the occurrence of delisting reasons under KOSDAQ listing regulations. This clearly falls under a delisting announcement rather than a general regulatory filing or any other category.

감사보고서제출
Audit Report / Information Classification · 90% confidence The document is titled “감사보고서 제출” (Audit Report Submission) and contains the auditor’s opinion, key audited financial figures, details on accounting periods, auditor’s name, and related disclosures. It is a standalone audit report filed separately from an annual report. Therefore, it fits the Audit Report / Information category. FY 2025

주권매매거래정지 (풍문 또는 보도 관련)
Regulatory Filings Classification · 80% confidence The document is a brief regulatory announcement notifying the suspension of trading in the company’s ordinary shares (‘주권매매거래정지’) with reasons, halt period, and legal basis per KOSDAQ market disclosure rules. It does not announce a delisting, dividend, share issue, management change, or financial report, so it falls into the general “Regulatory Filings” category as a miscellaneous regulatory notice.

조회공시요구(풍문또는보도) (감사의견 비적정설)
Regulatory Filings Classification · 88% confidence The document is a Korean stock exchange inquiry notice (“조회공시요구”) requesting disclosure regarding a rumor of a non-standard audit opinion. It is neither a financial report nor an earnings release but a regulatory request for clarification. This fits the broad “Regulatory Filings” category as a non-standard announcement.
2026-03-24 Korean
단일판매ㆍ공급계약체결
Regulatory Filings Classification · 85% confidence The document is a regulatory disclosure detailing the execution of a single sales and supply contract (contracting partner, amounts, terms, dates). It is not an earnings release, investor presentation, M&A notice, management change, director dealing, or any financial report. There is no specific category for material contract announcements, so under the fallback rules it should be classified as a general regulatory filing (RNS).
