[기재정정]주식매수선택권부여에관한신고
Regulatory Filings Classification · 1% confidence The document is a Korean regulatory disclosure (“공시”) concerning the grant (and correction) of stock purchase options (“주식매수선택권 부여”). It provides detailed terms of the option grant—exercise price, period, fair value, vesting, board and shareholder approvals, etc.—but is not an earnings release, dividend notice, management change, share repurchase, or annual/interim report. There is no dedicated category for stock‐option grant announcements, so by exclusion this is a general regulatory filing. Thus it falls into the fallback “Regulatory Filings” category (RNS).

감사보고서제출
Audit Report / Information Classification · 1% confidence The document is a regulatory filing from the Korean stock exchange (KRX) titled 'Audit Report Submission' (감사보고서 제출). It provides a summary of the audit opinion, key financial data (assets, liabilities, revenue, profit), and auditor information. While it contains financial data, it is a standardized regulatory announcement summarizing the audit results rather than the full annual report (10-K) or a standalone audit report (AR). According to the 'Menu vs Meal' rule, this is an announcement of the audit report's submission, making it a Regulatory Filing (RNS). FY 2025

주주총회집중일개최사유신고
Regulatory Filings Classification · 1% confidence The document is a formal regulatory filing submitted to the KRX (Korea Exchange) regarding the 'Reason for holding a General Meeting of Shareholders on a concentrated date'. It explains why the company (Seokgyung AT) is holding its AGM on a date that coincides with other companies' meetings, citing audit schedules and reporting obligations. Since this is a specific regulatory disclosure regarding meeting logistics rather than the meeting materials themselves or a proxy statement, it falls under the general regulatory filing category.
