동일인등출자계열회사와의상품ㆍ용역거래변경
Regulatory Filings Classification · 82% confidence The document is a mandatory Korean securities/stock exchange disclosure detailing changes in related-party transactions (goods and services with affiliates of the controlling shareholder). It lists amounts, periods, contract terms, and compliance with Fair Trade Act reporting requirements. It is neither a full financial report (IR, 10-K, AR) nor an earnings release, nor board/management change, M&A, share issue, dividend notice, etc. This type of affiliate transaction disclosure falls under miscellaneous regulatory filings. Therefore, it is classified as Regulatory Filings (RNS).

분기보고서 (2026.03)
Interim / Quarterly Report Classification · 98% confidence The document is the Korean ‘분기보고서’ for the 50th fiscal year first quarter (2026.01.01–2026.03.31) of S-1 Co., Ltd., containing extensive unaudited quarterly financial statements, segment results, business overview, risk management, contracts, R&D details and other substantive data. It is not merely an announcement of a report but the report itself. Therefore, it is classified as an Interim / Quarterly Report. Q1 2026

임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 95% confidence The document is a mandatory ‘임원ㆍ주요주주 특정증권등 소유상황보고서’ filed with the Financial Services Commission and Korea Exchange, detailing an officer’s personal shareholdings and transaction history. This matches the insider share transactions/disclosure category rather than a financial report. Under our taxonomy, this is classified as Director’s Dealing (Code: DIRS).

최대주주등소유주식변동신고서
Major Shareholding Notification Classification · 85% confidence The document is a ‘최대주주등 소유주식변동신고서’ (Major Shareholder Ownership Change Report) showing share count before and after for a major shareholder, with dates and reasons for changes (e.g., 장내매수). This is a notification of changes in significant share ownership levels. It matches the definition of a Major Shareholding Notification (Code: MRQ).

기업설명회(IR)개최(안내공시)
Regulatory Filings Classification · 25% confidence The document is a regulatory announcement (안내공시) notifying investors about the date, location, and format of an upcoming Investor Relations meeting (기업설명회 IR). It does not contain substantive financial data, the actual presentation materials, or the event’s slide deck. Therefore, it is a general regulatory filing announcing an IR event rather than the report itself or the presentation content. It falls under the catch‐all Regulatory Filings category (RNS).
2026-05-11 Korean
연결재무제표기준영업(잠정)실적(공정공시)
Earnings Release Classification · 95% confidence The document is a disclosure of preliminary (잠정) consolidated financial results for the first quarter of 2026, including sales, operating profit, and net income figures compared to previous periods. It explicitly states that the figures are provisional and subject to change after audit review. The document is relatively short (2538 characters) and is a public announcement of earnings results rather than a full detailed report. It is not a full Annual Report (10-K) or Interim Report (IR) because it lacks comprehensive financial statements and detailed analysis. It is also not a simple earnings release (ER) because it provides more detailed provisional financial data and is labeled as a fair disclosure (공정공시) in Korea, which aligns with a Capital/Financing Update or Earnings Release. Given the nature of the document as a preliminary earnings announcement with financial figures and the Korean context of 공정공시, the best fit is Earnings Release (ER). Q1 2026
