정기주주총회결과
Declaration of Voting Results & Voting Rights Announcements Classification · 1% confidence The document reports the outcomes of the company’s 23rd regular general shareholders’ meeting, including vote counts and percentages for each agenda item, appointment resolutions, and approval of financial statements.

사업보고서 (2025.12)
Audit Report / Information Classification · 1% confidence The document is a standalone consolidated audit report (“연결감사보고서”) issued by an external accounting firm for the periods ending December 31, 2025 and 2024, containing the auditor’s opinion, core audit matters, auditor and management responsibilities, and the audited consolidated financial statements with notes. It is not the full Annual Report nor an announcement of a filing, but a dedicated audit report. This matches the definition of an Audit Report / Information. FY 2025

[기재정정]주주총회소집공고
Regulatory Filings Classification · 1% confidence The document is a correction notice (“정정신고”) for a shareholders’ meeting convocation (“주주총회소집공고”), including revised financial statements agenda for approval. It is not the full Annual Report or audit report, nor is it a post‐meeting voting result. It is primarily a regulatory announcement to shareholders of an upcoming AGM. None of the more specific categories (e.g., earnings release, board change, dividend, share issue, proxy statement in the US context) perfectly match a Korean convocation notice, so the best fit under our taxonomy is the general Regulatory Filing category (RNS).

[기재정정]의결권대리행사권유참고서류
Proxy Solicitation & Information Statement Classification · 1% confidence The document is a 'Correction Report' (정정신고) for a 'Proxy Solicitation & Information Statement' (의결권대리행사권유참고서류). It details specific corrections made to financial statements following an external audit. Since the primary purpose of this document is to provide shareholders with updated information and proxy materials for an upcoming meeting, it falls under the Proxy Solicitation & Information Statement category.

감사보고서제출
Audit Report / Information Classification · 1% confidence The document is a regulatory filing titled '감사보고서 제출' (Submission of Audit Report) from the company ALT. It provides a summary of financial statements, audit opinions, and key financial metrics (assets, liabilities, profit/loss) for the fiscal year. While it contains financial data, it is a standard regulatory disclosure form used in the Korean market to announce the completion and submission of the audit report to the regulator, rather than the full, multi-page annual report document itself. Therefore, it is classified as a regulatory filing. FY 2025
