Korean material disclosures, in English

816 filings from 475 listed companies, 2026-08-25 to 2026-09-21, sorted into 18 event types. Korean companies file thousands of documents a month; almost all of them are routine. These are the ones that change what a reader would conclude — and each row links to the original filing so you can check us.

Read this first: what we left out, and why

This is not the full disclosure stream. Publishing a national disclosure feed in bulk raises questions we would rather not have to answer; publishing selected material events— the way a US Form 8-K works — does not. So we keep a fixed list of event types and drop everything else. The list is in our code, not in an editor’s head, which means the same filing gets the same treatment on a quiet Tuesday as on a busy one. Where a company has no English name registered we print its ticker instead of inventing a translation: 806 of 816 rows carry a real English name. We also dropped 46 further filings out of the 862 we captured, because they carry no ticker — unlisted filers, and subsidiary filings made under a parent’s name. We would rather report that subtraction than let 862 quietly become 816.

The 18 event types, and how often each one happened

Counted over 2026-08-25 to 2026-09-21. The order is by frequency, not by importance — we do not rank these, because which one matters depends on the company you are looking at.

What is not here

  • The money in the filing. A supply-contract disclosure states a contract value and a counterparty; we carry the event, not yet the amount. That is the next build.
  • Anything before 2026-08-25. The source does not hand back a bulk history, so the record starts the day we started collecting.
  • A view on whether any of this is good news. That is yours to form.

Financial Supervisory Service, DART — dart.fss.or.kr. Each row links to the filing it came from. The event names on this page are ours: we wrote them in English from the filing categories, and we say so rather than presenting them as the regulator’s own wording.

This page reports filings. It is not investment advice and not a recommendation to buy or sell anything.
