임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 87% confidence The document is a regulatory filing titled “임원ㆍ주요주주 특정증권등 소유상황보고서,” detailing an executive’s personal share transactions and changes in ownership of specified securities. It is clearly an insider trading report by a company director, matching the definition of Director’s Dealing. There is no indication it is a company repurchase or broader financial report. Thus, it should be classified as a Director’s Dealing report.

분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is the full Korean 분기보고서 (quarterly report) for the 30th fiscal period (2026.01.01–2026.03.31) of STI Co., Ltd., containing comprehensive financial statements, notes, MD&A (management’s discussion and analysis), auditor’s opinion, corporate overview, business operations, shareholder and governance details, and other sections typical of an interim/quarterly report. It is not merely an announcement or link to a report, but the report itself. Q1 2026

주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 95% confidence The document is titled '주식등의 대량보유상황보고서(약식)' which translates to 'Report on Large Shareholding Status (Abbreviated)'. It contains detailed information about shareholding changes, including the number of shares held, changes in shareholding percentages, and specific transaction dates. The document is from KB Asset Management and reports on shareholding changes in a company named (주)에스티아이. The content is consistent with a notification of changes in significant share ownership levels, which matches the definition of 'Major Shareholding Notification' (Code: MRQ). The document is lengthy (15,000 characters) and contains substantive data, not just an announcement or certification, so it is not a Regulatory Filing or Report Publication Announcement. Therefore, the correct classification is MRQ with high confidence.
2026-05-04 Korean
단일판매ㆍ공급계약체결
Regulatory Filings Classification · 80% confidence The document is a Korean regulatory announcement detailing the terms of a single sales and supply contract (단일판매ㆍ공급계약체결) between the company and Samsung Electronics, including contract amount, period, and conditions. It is neither an earnings release nor a financial report, but a specific material contract disclosure. None of the specialized categories (e.g., M&A, capital change, board changes) fit this type of contract notice. Therefore, it best falls under the fallback category for miscellaneous regulatory announcements: Regulatory Filings (RNS).

It contains specific details on the approval of financial statements, dividend resolutions, election of directors and auditors, and the voting results for each agenda item. This aligns perfectly with the definition of a Declaration of Voting Results & Voting Rights Announcement (DVA).
