Interim / Quarterly Report Classification · 92% confidence The document is titled “분기보고서” (Quarterly Report) covering the first quarter of fiscal 2026 (2026.01.01–2026.03.31). It is filed with the Financial Services Commission and Korea Exchange, includes detailed company overview, business activities, capital changes, share movements, and actual financial data for the quarter.

[기재정정]타법인주식및출자증권취득결정(자율공시)(종속회사의주요경영사항)
Regulatory Filings Classification · 55% confidence The document is a voluntary disclosure (자율공시) relating to a subsidiary’s decision to acquire shares and equity securities in another company, including a correction notice (“정정신고”). It is not an earnings release, management discussion, M&A bid proposal, financial report, or dividend/interest notice. Instead, it is a general regulatory announcement about a share acquisition transaction and subsequent amendment. As it does not neatly fit any targeted category such as M&A proposals (TAR), capital raising (CAP), or share repurchases (POS), it falls into the fallback “Regulatory Filings” category.
