(KOSDAQ: 161580) — research page\n\nAs of 2026-11-06 · kr-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is PHILOPTICS CO., LTD., listed on KOSDAQ under ticker 161580, with ISIN KR7161580006. The LEI is not on the record, as no GLEIF record is registered under 123-86-13175.

Auditor changes are not on the record, as the market's record does not carry them.\n\n## Events and halts\n\nThe lifecycle lines of listing, delisting, name change, domicile change and segment move are not on the record, as no lifecycle type map exists yet for this register. The halt flag shows the issuer as listed, 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.

No issuer years are sealed for this issuer, and the market's earliest sealed date is not on the record. The live record began on 2026-09-12.
