Interim / Quarterly Report Classification · 92% confidence The document is titled “분기보고서 (제22기) 2026년 01월 01일~2026년 03월 31일,” i.e., a quarterly report for Q1 2026, and contains detailed financial statements, capital changes, production data, and business narrative.

기업가치제고계획(자율공시)
Regulatory Filings Classification · 30% 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).
