It is a full interim/quarterly financial report, not merely an announcement or summary. This corresponds to the Interim / Quarterly Report category. · Q1 2026 | 2026-05-15 | Korean | | | [**주식등의대량보유상황보고서(일반)**](/filings/psk-holdings-inc/major-shareholding-notification/2026/45774993/) Major Shareholding Notification Classification · 85% confidence The document is a ‘주식등의 대량보유상황보고서(일반)’ filed under the Capital Markets Act (자본시장과 금융투자업에 관한 법률 제147조), detailing a person’s large shareholding, related parties, and changes in share counts. This matches a Major Shareholding Notification (code MRQ). | 2026-05-14 | Korean | | | [**기업설명회(IR)개최**](/filings/psk-holdings-inc/investor-presentation/2026/44833317/) Investor Presentation Classification · 75% confidence The document is an announcement of a 예정된 기업설명회(IR) event, listing date, time, venue, participants, purpose, and where IR materials will be posted. It is not a financial report or earnings release but an investor presentation event notice, which falls under the Investor Presentation category. | 2026-05-11 | Korean | | | [**기업가치제고계획(자율공시) ((2025년 이행현황))**](/filings/psk-holdings-inc/regulatory-filings/2026/39003968/) Regulatory Filings Classification · 95% confidence The document is titled '기업가치 제고 계획(자율공시)' which translates to 'Corporate Value Enhancement Plan (Voluntary Disclosure)'. It includes a plan name, key content about targets and performance evaluation, dividend information, and a decision date. The document mentions that detailed information is available in an attached report but does not itself contain comprehensive financial statements or detailed analysis. The length is only 1636 characters, which is quite short and more consistent with an announcement or summary rather than a full report. The document is a voluntary disclosure about the company's corporate value enhancement plan and its implementation status, including dividend details. This fits best under the category of Regulatory Filings (RNS) as it is a regulatory announcement of a plan and its status, not a full annual or interim report, nor a detailed investor presentation or earnings release. | 2026-04-30 | Korean | | | [**[기재정정]임원ㆍ주요주주특정증권등소유상황보고서**](/filings/psk-holdings-inc/directors-dealing/2026/34565055/) Director's Dealing Classification · 92% confidence The document is a detailed correction to the “임원ㆍ주요주주 특정증권등 소유상황보고서,” which is a statutory insider share ownership and transaction disclosure filed by a company director (an executive) and major shareholder. It lists shareholdings, changes (acquisitions/disposals), transaction dates, and corrected transaction price. This matches our “Director's Dealing” category, which covers insider share transactions by directors/executives. It is not a simple announcement of a report, nor an annual/interim report, but the actual insider transaction report form. | 2026-04-15 | Korean | | | [**주식등의대량보유상황보고서(일반)**](/filings/psk-holdings-inc/major-shareholding-notification/2026/34547661/) Major Shareholding Notification Classification · 97% confidence The document is a detailed "주식등의 대량보유상황보고서" (Major Shareholding Situation Report) filed under the Capital Markets Act, showing the number of shares and changes in ownership by a significant shareholder and related parties. It lists beneficial owners, share counts, percentages before and after the reporting date, reasons for changes, and detailed transaction history. This matches the definition of a Major Shareholding Notification (MRQ). There is no indication this is an announcement of a report publication or an earnings release, but rather the substantive report itself. | 2026-04-15 | Korean | | ## Browse filings by year 9 years - [2026 20 filings](/companies/psk-holdings-inc/2026/) - [2025 18 filings](/companies/psk-holdings-inc/2025/) - [2024 32 filings](/companies/psk-holdings-inc/2024/) - [2023 24 filings](/companies/psk-holdings-inc/2023/) - [2022 22 filings](/companies/psk-holdings-inc/2022/) - [2021 28 filings](/companies/psk-holdings-inc/2021/) - [2020 32 filings](/companies/psk-holdings-inc/2020/) - [2019 41 filings](/companies/psk-holdings-inc/2019/) - [2018 14 filings](/companies/psk-holdings-inc/2018/) [["13", "AGM Information"], ["1", "Annual Report"], ["53", "Audit Report / Information"], ["47", "Board/Management Information"], ["48", "Capital/Financing Update"], ["22", "Declaration of Voting Results & Voting Rights Announcements"], ["50", "Delisting Announcement"], ["20", "Director's Dealing"], ["6", "Earnings Release"], ["19", "Interim / Quarterly Report"], ["12", "Investor Presentation"], ["23", "M&A Activity"], ["24", "Major Shareholding Notification"], ["17", "Management Reports"], ["45", "Notice of Dividend Amount"], ["46", "Proxy Solicitation & Information Statement"], ["18", "Regulatory Filings"], ["42", "Report Publication Announcement"], ["51", "Share Issue/Capital Change"], ["52", "Transaction in Own Shares"]] [["100", "Korean"]] Financial Reporting & Info Annual General Meeting Debt Information Equity Information Investor Communication Listing/Delisting M&A, Partnerships & Legal Management & Remuneration Other Filing type Language Start date End date Apply filters [Clear](/companies/psk-holdings-inc/) Report missing filing Download originals Download Markdown | | ID | Filing | Released | Lang | Actions | | --- | --- | --- | --- | --- | --- | | [2026](/companies/psk-holdings-inc/2026/) 15 filings | | | | | | | | 46367498 | [**분기보고서 (2026.03)**](/filings/psk-holdings-inc/interim-quarterly-report/2026/46367498/) Interim / Quarterly Report Classification · 95% confidence The document is titled ‘분기보고서’ (Quarterly Report) covering the period January 1 2026 to March 31 2026 and includes extensive financial statements (summary financials, consolidated statements, notes, segment reporting), management analysis, risk disclosures, and auditor’s report.
