Filing Released Lang Actions
기업가치제고계획(자율공시)
Regulatory Filings Classification · 0% confidence The document is a voluntary (“자율공시”) announcement of a corporate value enhancement plan (기업가치 제고계획) by 에이에스텍, including targets, policy on shareholder returns, and related tax/dividend details. It does not present financial results (so it’s not an ER or IR), nor is it an AGM material, proxy statement, dividend notice, share issue, buyback, M&A, or other specific category. It is a standalone regulatory announcement that does not neatly fit the other defined types, so it defaults to a general regulatory filing (RNS).

사외이사의선임ㆍ해임또는중도퇴임에관한신고

정기주주총회결과
Declaration of Voting Results & Voting Rights Announcements Classification · 1% confidence The document is a concise disclosure of the results of the company’s regular shareholders’ (annual general) meeting (‘정기주주총회 결과’). It lists each agenda item, voting outcomes (approval rates, vote counts), dividend resolutions, and director appointments. This matches the definition for Declaration of Voting Results & Voting Rights Announcements (Code: DVA), not a full annual report or separate management commentary. There is no indication of an attached financial report or regulatory filing beyond the meeting results. Therefore, the correct classification is DVA.
