Editor’s note: This is general educational information about how corporate results reach the market, first as a company announcement and later inside an audited periodic filing. It is not investment advice, and the rules, dates and figures below are taken from the official documents listed at the end.
Results appear twice, and the two appearances are governed by different rules. The first is an announcement the company makes because it has material information and a duty to release it. The second is a periodic filing that carries the same numbers inside a document prepared to a reporting standard. Investors who treat the two as one event are usually surprised by the gap between them, which is where restatements, rounding, and reclassifications live.
Two Documents, Two Legal Characters
The United States draws the line explicitly. Under Item 2.02 of Form 8-K, when a registrant or anyone acting on its behalf makes a public announcement disclosing material non-public information about results of operations or financial condition for a completed quarterly or annual period, the registrant must disclose the date of the announcement, identify it briefly, and include its text as an exhibit. A report on Form 8-K is generally to be filed or furnished within four business days.
The word furnished is doing a great deal of work there. The general instructions state that information furnished under Item 2.02, or under Item 7.01 for Regulation FD disclosure, is not deemed filed for the purposes of the Exchange Act unless the registrant says otherwise. The earnings release enters the public record as a company statement rather than as a certified filing, and the certified numbers arrive later in the periodic report.
The instructions also anticipate the earnings call. No Form 8-K is required for material non-public information disclosed orally, telephonically, by webcast or by broadcast where the presentation is complementary to a written announcement already furnished under Item 2.02 and begins within 48 hours of it. The call is treated as an extension of the release, not as a separate disclosure event.
Korea’s Version Runs Through the Exchange
Korean disclosure is organised around the Korea Exchange rather than a single federal form, and the categories are visible in the rules the Financial Services Commission has been amending. When the FSC approved revised disclosure rules on January 28, 2026, it expanded the items subject to mandatory English disclosure to all disclosure items required by KRX rules, listing material information in its entirety, described as 55 items, together with fair disclosure and inquired disclosure.
Those three categories map the ways results can reach the market. Material information is what the company must announce. Fair disclosure is the route for information a company chooses to release to some parties and must therefore release to everyone. Inquired disclosure is the exchange asking a company to confirm or deny something, which is how a statement is produced on the exchange’s timing rather than on the company’s own.
The timing rules attached to that expansion show how seriously the lag is treated. Mandatory English disclosure began in January 2024 for listed companies with assets of KRW10 trillion or more and foreign ownership of 5 percent or more, or assets of KRW2 trillion or more and foreign ownership of 30 percent or more. From May 2026 it applies to all KOSPI-listed companies with assets of KRW2 trillion or more, raising the population from 111 companies, measured on total assets as of end-2024, to 265. The largest companies, those at KRW10 trillion or more, must file the English version on the same day as the Korean disclosure in principle, while the newly covered KRW2 trillion group has three days. A third stage covering all 848 KOSPI-listed companies was pulled forward from May 2028 to March 2027.
An earlier phase of the same programme, proposed on November 17, 2025, had required English disclosure of 26 key items including securities issuance within three business days of the Korean filing. The direction of travel is from a lag measured in business days toward same-day parity for the largest issuers.
What Else Changed in the Same Rulebook
Two adjacent changes are worth noting because they alter what the second document contains. From March 2026 Korean companies must disclose annual general meeting voting results by agenda item, including the percentages in assent, dissent and abstention on the day of the meeting, and the same figures plus total shares in each category through the periodic business report. Previously the disclosure showed only whether an agenda item had passed.
From May 2026 executive compensation disclosure must set out total shareholder return and operating profit for the most recent three years alongside total executive compensation, give a rationale for each compensation category, and bring every form of stock-based compensation, including restricted stock units, onto the total and individual compensation forms with the cash value of unfulfilled awards written beside them.
Analysis: The Gap Between the Two Reports Is the Information
Treating the announcement and the filing as one event throws away the most useful comparison available. The first document is management’s account of the period, released under time pressure, and in the US framework it is expressly furnished rather than filed. The second is the same period rendered inside a reporting framework with an audit or review attached, and it is the one that carries the legal weight.
Three things can differ between them, and each has a different meaning. Numbers can move, which is the rarest and the most serious. Presentation can change, where a figure highlighted in the release is reclassified or de-emphasised in the filing. And items absent from the release can appear in the filing, which is where segment detail, related-party transactions and contingencies tend to show up. None of those is visible if a reader stops at the headline.
The Korean rules make a fourth comparison possible for foreign investors. Until recently the English disclosure arrived after the Korean one, so the same company was effectively speaking to two audiences at different times. The staged reform closes that gap deliberately and unevenly: same day in principle for the KRW10 trillion group, three days for the KRW2 trillion group, with the population rising from 111 to 265 and then to 848. Which tier a company sits in tells a reader how quickly an English-reading investor learns what a Korean-reading investor already knows.
The inquired disclosure category deserves more attention than it usually gets. A company that announces results when it chooses is behaving normally. A company that produces a disclosure because the exchange asked is answering a question the market raised first, and the existence of that mechanism in the KRX rules means the timeline of a Korean disclosure sometimes records who moved first.
For anyone reading a set of results, the practical sequence is to note the date and character of the release, to check whether an accompanying call occurred within the window that treats it as part of the release, and then to read the periodic filing against the release rather than instead of it. The second document rarely contradicts the first. It routinely completes it.
