(KOSPI: 028100) — research page\n\nAs of 2026-11-06 · kr-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Dong-Ah Geological Engineering Company LTD., listed on KOSPI under ticker 028100, with ISIN KR7028100006. The LEI is not on the record. The security type is Corporate, the segment is not on the record, and the sector is 기반조성 및 시설물 축조관련 전문공사업.

Auditor changes are not on the record, as the register has no lifecycle type map yet.\n\n## Events and halts\n\nListing, delisting, name change, domicile change and segment move are not on the record, as the register has no lifecycle type map yet. The halt flag is clear: the issuer is listed and not halted.\n\n## Orderability\n\nThe outcome cannot be determined. The chapter's orderability section carries no client categories, so the outcome cannot name its client category.

The issuer has no sealed years. The live record began on 2026-09-12.
