주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 95% confidence The document is titled “주식등의 대량보유상황보고서(일반)” (Report on Large Shareholding Situations) and details the number of shares and voting rights held by a major shareholder and related parties, including changes in holdings and reasons.

결산기변경안내
Regulatory Filings Classification · 50% confidence The document is a corporate announcement notifying investors of a change in the company’s fiscal year end (결산기 변경 안내), approved at the shareholders’ meeting on 2026-03-27, with detailed new accounting periods. It is not a financial report itself, not a dividend or share issue, nor a call transcript or earnings release. It represents a regulatory corporate action that does not fit any more specific category, so it falls under the fallback Regulatory Filings (RNS).

Audit Report / Information Classification · 99% confidence The document is a formal 'Audit Report' (감사보고서) for '주식회사 이엠티' (EMT Co., Ltd.) covering the fiscal years 2024 and 2025. It includes the independent auditor's report, financial statements (Statement of Financial Position, Statement of Comprehensive Income, Statement of Changes in Equity, Statement of Cash Flows), and detailed notes to the financial statements. This is a comprehensive annual financial disclosure, not an announcement of a report, and fits the definition of an Audit Report/Information (AR) or a comprehensive financial report. Given the inclusion of the full audit opinion and financial statements, 'AR' is the most accurate classification. FY 2025

최대주주변경
Major Shareholding Notification Classification · 95% confidence The document is a formal regulatory announcement regarding a change in the company's largest shareholder (최대주주 변경). It details the transition from 'Jaese Energy' to 'Jaese Tech' due to a corporate spin-off (인적분할). Since this is a specific regulatory disclosure regarding ownership structure and does not fit into categories like M&A (which usually implies a takeover or merger of two distinct entities) or Board changes, it is best classified as a general regulatory filing.
