Listed Company Advisory | Timely disclosure and fair disclosure obligations

Disclosure is the area where listed companies most often incur sanctions, usually not from bad faith but from failing to recognize that an internal decision has already triggered a public disclosure duty.

What triggers a timely disclosure duty

Once a company's board or management resolves on a matter listed in the Korea Exchange disclosure regulations — a large-scale investment, a merger, a change of the largest shareholder, or a significant contract — the disclosure clock starts running from the moment the decision is made, not from when a press release goes out. Companies frequently underestimate how early that trigger point falls, especially where a matter is discussed informally before a formal board resolution.

Ad hoc disclosure vs. fair disclosure

Ad hoc (timely) disclosure obligations apply to material corporate events regardless of who becomes aware of them, while fair disclosure rules govern selective communication of undisclosed material information to analysts, institutional investors, or media (자본시장과 금융투자업에 관한 법률 제391조 및 한국거래소 공시규정). An advisory review typically checks both the substance of what is being disclosed and the timing and channel used to disclose it.

Consequences of a disclosure violation

Violations can result in a public unfaithful disclosure designation, corrective disclosure requirements, fines imposed by the Exchange, or in more serious cases referral for investigation on suspected market manipulation or unfair trading. A pattern of violations can also affect the company's management issue designation status, which has knock-on effects for investor relations.

Listed Company Advisory | Board and general shareholder meeting procedure

The Commercial Act (상법) sets out detailed procedural requirements for convening board and shareholder meetings, and listed companies face additional layers under the Financial Investment Services and Capital Markets Act, particularly around electronic voting and shareholder proposal rights.

Notice periods and convening defects

A general shareholders' meeting must generally be convened with at least two weeks' prior notice to shareholders (상법 제363조), and failure to meet notice or agenda disclosure requirements can expose a resolution to challenge through a lawsuit to revoke a shareholders' meeting resolution. Listed companies also need to reconcile these notice periods with electronic disclosure filing deadlines that run on a separate clock.

Shareholder proposals and activist engagement

Minority shareholders holding the statutory minimum shareholding percentage can request that specific agenda items be placed on the shareholders' meeting agenda (상법 제363조의2), and listed companies increasingly need a process for evaluating and responding to these proposals, including from activist investors, within statutory deadlines.

Independent director and audit committee requirements

Companies above certain asset thresholds are required to appoint outside directors and, in many cases, form an audit committee with independent director majority under the Commercial Act. Advisory review at this stage often focuses on director independence criteria and whether committee composition still meets statutory requirements after personnel changes.

Listed Company Advisory | Related-party transactions and internal transaction approval

Transactions between a listed company and its largest shareholder, affiliates, or executives carry a heightened approval and disclosure burden precisely because of the conflict-of-interest risk they present to minority shareholders.

Board approval threshold for related-party deals

Transactions with the largest shareholder or specially related persons above a certain size generally require prior board approval, and transactions exceeding a higher threshold require approval at the general shareholders' meeting (상법 제542조의9). Structuring a transaction to fit within, rather than around, these thresholds is a recurring point of advisory review.

Disclosure of related-party transactions

Beyond internal approval, related-party transactions above the relevant size must also be separately disclosed to the market, and the disclosure content is scrutinized for whether the terms were on an arm's-length basis. Inadequate disclosure here is a common source of Exchange inquiries even when the underlying transaction itself was legitimate.

Listed Company Advisory | Capital markets transactions: rights offerings, CBs, and M&A disclosure

Raising capital or pursuing M&A as a listed company means the transaction itself becomes public information subject to registration and disclosure requirements well before closing.

Securities registration statements

A public offering or rights offering above the statutory threshold generally requires filing a securities registration statement with the Financial Services Commission before the offering can proceed (자본시장과 금융투자업에 관한 법률 제119조), and the statement must be reviewed for accuracy since misstatements can give rise to investor liability claims.

Convertible and exchangeable bond issuance

Issuance of convertible bonds or exchangeable bonds by a listed company triggers both disclosure obligations and, where the issuance is to a specific third party rather than existing shareholders, additional scrutiny of whether the pricing and allottee selection could dilute or disadvantage existing shareholders.

M&A announcement timing

Merger and acquisition discussions for a listed company often need to be disclosed once they reach a level of concreteness well before signing, and coordinating confidentiality during negotiation with the disclosure duty is one of the more delicate judgment calls in listed company advisory work.
