This matches the definition of an Interim/Quarterly Report (IR). · Q1 2026 | 2026-05-15 | Korean | | | [**최대주주등소유주식변동신고서**](/filings/bookook-steel/regulatory-filings/2026/44130314/) Regulatory Filings | 2026-05-08 | Korean | | | [**주식등의대량보유상황보고서(일반)**](/filings/bookook-steel/regulatory-filings/2026/44130119/) Regulatory Filings | 2026-05-08 | Korean | | | [**주식등의대량보유상황보고서(일반)**](/filings/bookook-steel/major-shareholding-notification/2026/35617066/) Major Shareholding Notification Classification · 90% confidence The document is a detailed ‘주식등의 대량보유상황보고서(일반)’ (Report on the status of large shareholdings) filed under the Korean Capital Markets Act. It provides full disclosure of shareholdings by a major shareholder and related parties, including precise share counts, percentages, changes and contract details. This corresponds exactly to a notification of significant share ownership levels (Major Shareholding Notification). | 2026-04-23 | Korean | | | [**최대주주등소유주식변동신고서**](/filings/bookook-steel/major-shareholding-notification/2026/34653801/) Major Shareholding Notification Classification · 98% confidence The document is a formal notification of changes in share ownership by the largest shareholder and related persons, titled “최대주주등소유주식변동신고서” (Major Shareholder Shareholding Change Report).

It is not a full annual or interim financial report, nor is it an investor presentation, earnings release, M&A announcement, board change, or other defined category. It also is not merely a notice pointing to an attached report (so it’s not RPA), and it does not strictly fit ‘Notice of Dividend Amount’ since it’s about policy and plan rather than setting payment records/dates. Therefore it falls into the fallback “Regulatory Filings” category. | 2026-03-27 | Korean | | ## Browse filings by year 9 years - [2026 14 filings](/companies/bookook-steel/2026/) - [2025 24 filings](/companies/bookook-steel/2025/) - [2024 16 filings](/companies/bookook-steel/2024/) - [2023 19 filings](/companies/bookook-steel/2023/) - [2022 31 filings](/companies/bookook-steel/2022/) - [2021 13 filings](/companies/bookook-steel/2021/) - [2020 12 filings](/companies/bookook-steel/2020/) - [2019 12 filings](/companies/bookook-steel/2019/) - [2018 2 filings](/companies/bookook-steel/2018/) [["13", "AGM Information"], ["1", "Annual Report"], ["53", "Audit Report / Information"], ["47", "Board/Management Information"], ["22", "Declaration of Voting Results & Voting Rights Announcements"], ["20", "Director's Dealing"], ["6", "Earnings Release"], ["19", "Interim / Quarterly Report"], ["24", "Major Shareholding Notification"], ["45", "Notice of Dividend Amount"], ["46", "Proxy Solicitation & Information Statement"], ["18", "Regulatory Filings"], ["42", "Report Publication Announcement"], ["52", "Transaction in Own Shares"]] [["100", "Korean"]] Financial Reporting & Info Annual General Meeting Equity Information Investor Communication Management & Remuneration Other Filing type Language Start date End date Apply filters [Clear](/companies/bookook-steel/) Report missing filing Download originals Download Markdown | | ID | Filing | Released | Lang | Actions | | --- | --- | --- | --- | --- | --- | | [2026](/companies/bookook-steel/2026/) 14 filings | | | | | | | | 46367128 | [**분기보고서 (2026.03)**](/filings/bookook-steel/interim-quarterly-report/2026/46367128/) Interim / Quarterly Report Classification · 95% confidence The document is titled “분기보고서” (Quarterly Report) for the period 2026.01.01–2026.03.31 (Q1 2026).
