(KOSDAQ: 125020) — research page\n\nAs of 2026-11-06 · kr-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is TC Materials Co., Ltd., listed on KOSDAQ under ticker 125020, with ISIN KR7125020008. The LEI is not on the record; no GLEIF record is registered as 610-81-21529.

The issuer's 19 filings are below the KOSDAQ median of 33 and below the sector median of 53.0.\n\n## Auditor\n\nThe auditor of record is 대주회계법인. Its location is not on the record. Auditor changes are not on the record, as this 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 this register has no lifecycle type map yet. The halt flag is listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable.
