(KOSDAQ: 355690) — research page\n\nAs of 2026-11-06 · kr-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is ATUM CO., LTD., listed on KOSDAQ under ticker 355690, with ISIN KR7355690009.

The issuer is listed and not halted.\n\n## Orderability\n\nThe outcome is not determinable. The chapter's orderability section carries no client_categories, so the outcome cannot name its client category.

The issuer's years are sealed in the store as 2021 through 2026 but are not served as of a date, and the as-of door answers not_sealed. The live record began on 2026-09-12.\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=01444380 (identity.jurisdiction)\n- https://mcp.kr-cm-kg.ai/events/KOSDAQ/355690 (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=20260318001384 (the auditor)\n- https://mcp.kr-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.kr-cm-kg.ai/record/KOSDAQ/355690 (the record)\n",
