(KOSPI: 357430) — research page\n\nAs of 2026-11-06 · kr-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is MASTERN PREMIER REIT 1 Co., Ltd., listed on KOSPI under ticker 357430, with ISIN KR7357430008. The LEI is not on the record, as no GLEIF record is registered under 172-88-01447. The security type is Corporate, the segment is not on the record, the sector is 부동산 임대 및 공급업, and the jurisdiction is South Korea (DART filer with a corporate registration number). The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 41 filings across 32 filing days in the window 2025-11-06 to 2026-11-06. The median gap between filing days is 8 days. The latest filing is dated 2026-11-06, is of type exchange_bulletin, and is 0 days before the record date of 2026-11-06.

The sector median cadence gap is 6 days, the sector median filings count is 74, and the sector median latency is 1 day across 27 issuers.\n\n## Auditor\n\nThe auditor of record is 삼덕회계법인. Its location is not on the record. The record does not carry auditor changes, as no lifecycle type map for this register is yet in place.\n\n## Events and halts\n\nThe record does not carry listing, delisting, name change, domicile change or segment move events, as no lifecycle type map for this register is yet in place. The halt flag is listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable.

A licensed row is served only to an agent whose firm holds that licence (licensor, entitlement). No licensed row is loaded.\n\n## As-of depth\n\nThe market's vintage is not sealed. No issuer years are sealed for this issuer. The market's earliest sealed date is not on the record. The live record began on 2026-09-12. The years 2021, 2022, 2023, 2024, 2025 and 2026 are sealed in the store but not served as of a date. The as-of door answers not_sealed.\n\n## Sources\n\n8 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://kind.krx.co.kr/corpgeneral/corpList.do?method=download&searchType=13 (identity.exchange)\n- https://data.krx.co.kr/comm/bldAttendant/getJsonData.cmd (identity.isin)\n- https://opendart.fss.or.kr/api/company.json?corp_code=01442966 (identity.jurisdiction)\n- https://mcp.kr-cm-kg.ai/events/KOSPI/357430 (the disclosure lines)\n- https://kind.krx.co.kr/investwarn/tradinghaltissue.do?method=searchTradingHaltIssueMain (the halt flag)\n- https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260618000369 (the auditor)\n- https://mcp.kr-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.kr-cm-kg.ai/record/KOSPI/357430 (the record)\n",
