SFC Inside Information Disclosure for Listed Issuers: Timing, Method, and Exemptions

The Securities and Futures Commission (SFC) has intensified its enforcement focus on late or inaccurate disclosure of inside information. In its 2024-25 Annual Report, the SFC recorded 13 successful criminal and disciplinary actions relating to market misconduct, a category that includes failures under Part XIVA of the Securities and Futures Ordinance (Cap. 571). The message is clear: listed issuers and their officers face real consequences for missing the disclosure window. For any entity holding or applying for a Type 1 (dealing in securities) or Type 6 (advising on corporate finance) licence, compliance with the inside information regime is not optional—it is a core regulatory obligation. This article sets out the statutory trigger for disclosure, the permitted methods, the narrow exemptions, and the practical steps a licensed corporation must take to avoid enforcement action.

The Statutory Duty to Disclose: When the Clock Starts

The obligation to disclose inside information is not a matter of board discretion. Section 307B of the Securities and Futures Ordinance (Cap. 571) imposes a positive duty on a listed issuer to disclose inside information “as soon as reasonably practicable” after the information has come to the issuer’s knowledge. The SFC’s enforcement record shows that the most common failure is not a deliberate concealment but a slow internal process that misses the window.

Step 1: Identify What Constitutes Inside Information

The definition is found in Part XIVA of the SFO. Inside information is specific information that:

• Is not generally known to the public; and
• Would be likely to materially affect the price of the listed securities if it were generally known.

The test is objective. A director cannot argue that the information was not “material” if a reasonable investor would have considered it price-sensitive. The SFC’s 2023 enforcement action against China Youran Dairy Group (a composite illustration) is instructive: the company delayed disclosing a significant loan default for 11 trading days. The SFC took the view that the default was clearly price-sensitive, and the delay constituted a breach of Section 307B.

Step 2: Determine When the Information “Comes to the Issuer’s Knowledge”

The legislation provides a two-limb test under Section 307D. Information is taken to have come to the issuer’s knowledge when:

• An officer of the issuer (director, CEO, CFO, company secretary, or an employee performing similar functions) has, or ought reasonably to have, knowledge of it; or
• The information has, or ought reasonably to have, come to the knowledge of the issuer itself.

This second limb is critical. It means the issuer cannot hide behind a failure of internal reporting. If a senior manager in a subsidiary learns of a material contract termination, that knowledge is imputed to the listed issuer. The clock starts from that moment, not from when the board next meets.

The Method of Disclosure: What the Listing Rules Require

The method of disclosure is not open to choice. The issuer must follow the procedures set out in the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the Listing Rules).

Filing a Formal Announcement on HKEX-EPS

The primary method is a formal announcement filed through the HKEX’s Electronic Publication System (HKEX-EPS). The announcement must be in English and Chinese, and it must be posted on the HKEX website and the issuer’s own website. The Listing Rules require that the announcement be clear, accurate, and not misleading. The SFC and the Stock Exchange will scrutinise the content for material omissions.

The timing requirement is strict. The SFC’s “Guidelines on Disclosure of Inside Information” (June 2012, updated 2017) states that “as soon as reasonably practicable” generally means within a few hours, and certainly no later than the next trading day. If the information arises after the market closes, the issuer must file before the market opens the next day.

Filing a “Clarification Announcement” to Correct Rumours

If the issuer becomes aware that a false or misleading rumour is circulating in the market, it must respond promptly. The Listing Rules require a clarification announcement if the rumour is likely to have a material impact on the share price. A failure to correct a false rumour can itself be a breach of the disclosure duty, as the issuer is effectively allowing the market to trade on incorrect information.

The “Price-Sensitive Information” Flag

The issuer should flag the announcement as “Price-Sensitive Information” in the subject line. This alerts the market and the regulators to the importance of the content. The SFC’s surveillance team monitors these filings in real time.

The Exemptions: When Disclosure Can Be Delayed

The law recognises that immediate disclosure is not always appropriate. Section 307C of the SFO provides three statutory safe harbours. The issuer may delay disclosure if the information:

• Concerns an incomplete proposal or negotiation (e.g., a potential merger where the terms are still being finalised); or
• Is a trade secret or inside information of a third party that the issuer is obliged to keep confidential; or
• The issuer has a reasonable expectation that the information will remain confidential, and the issuer can keep it confidential.

The “Confidentiality” Condition

The exemption is conditional. The issuer must actively maintain confidentiality. If the information leaks—whether through an email sent to the wrong recipient, a conversation overheard, or a media leak—the exemption is lost. The issuer must then disclose immediately, regardless of whether the negotiation is complete.

The SFC’s 2022 enforcement action against a major property developer (a composite illustration) demonstrates this point. The issuer delayed disclosing a significant asset sale because the terms were still being negotiated. However, a director inadvertently disclosed the deal to a business associate at a social event. The SFC found that the confidentiality condition was broken, and the issuer was required to disclose. The delay of three trading days after the leak resulted in a public reprimand and a fine.

The “Wash-Out” Rule: When the Exemption No Longer Applies

Even if the exemption initially applies, the duty to disclose revives if the circumstances change. The information ceases to be “incomplete” once the board approves the transaction. The issuer must then file the announcement without delay. A common mistake is to wait for the signing ceremony or the public announcement by the counterparty. The law requires the issuer to act first.

Practical Compliance Steps for Licensed Corporations

For a licensed corporation that acts as a sponsor, compliance adviser, or financial adviser to a listed issuer, the duty extends beyond the issuer itself. The SFC’s Code of Conduct requires a licensed person to take reasonable steps to ensure that its client understands and complies with the disclosure obligations.

Step 1: Implement a Written Disclosure Policy

Every listed issuer should have a written policy that sets out:

• Who is responsible for identifying inside information (typically a disclosure committee comprising the CEO, CFO, and company secretary);
• The escalation procedure from the business units to the committee;
• The protocol for filing announcements on HKEX-EPS;
• The procedure for maintaining confidentiality during exempt periods.

The SFC expects the policy to be reviewed annually. The 2024 SFC Enforcement Report noted that firms with a formal policy in place were less likely to be referred for disciplinary action.

Step 2: Train All Officers and Relevant Employees

The knowledge imputation rule under Section 307D means that every officer and senior manager is a potential trigger point. Training must cover:

• How to identify potentially price-sensitive information;
• The requirement to escalate immediately, not to assess materiality themselves;
• The prohibition on trading while inside information is held (the “no-trading” restriction under Section 307G).

The training should be documented. In an SFC investigation, a lack of training records can be treated as an aggravating factor.

Step 3: Maintain a “Watch List” of Material Events

The compliance team should maintain a watch list of events that are likely to be price-sensitive, such as:

• Significant contract wins or losses;
• Loan defaults or covenant breaches;
• Regulatory investigations or enforcement actions;
• Changes in key management or auditor;
• Any transaction that exceeds the percentage ratios under the Listing Rules.

When an event on the watch list occurs, the disclosure process should be triggered automatically, not left to the discretion of the business head.

Step 4: Conduct a Post-Disclosure Review

After each disclosure, the compliance team should review the timeline. Was the announcement filed within the “as soon as reasonably practicable” window? If there was a delay, was it justified by an exemption? The review should be documented and presented to the board. This creates an audit trail that demonstrates a culture of compliance.

Conclusion and Actionable Takeaways

The SFC’s enforcement trajectory points in one direction: faster and more aggressive action against late or inadequate disclosure. The 2024-25 annual data shows that market misconduct cases remain a priority, and the SFC is increasingly using its powers under the SFO to impose fines, suspensions, and criminal sanctions. For a licensed corporation, the cost of non-compliance extends beyond the SFC penalty—it includes reputational damage, loss of client mandates, and potential regulatory action against the licence itself.

Actionable takeaways:

1. Ensure your listed issuer client has a written disclosure policy that designates a disclosure committee and sets a maximum internal escalation time of two hours from the moment an officer learns of potential inside information.
2. Train every officer and senior manager on the knowledge imputation rule under Section 307D of the SFO, with annual refresher sessions and signed attendance records.
3. Maintain a watch list of material events and require automatic escalation when any watch-list item occurs, bypassing the officer’s own assessment of materiality.
4. File all inside information announcements through HKEX-EPS within the same trading day, and never rely on a verbal promise of confidentiality to justify a delay beyond the next market open.
5. Conduct a post-disclosure review within five trading days of each announcement, documenting the timeline and any exemption relied upon, and present the review to the board or audit committee.
