Restricted Periods for Directors Dealing in Company Securities Post-Listing

The Hong Kong Stock Exchange’s (HKEX) recent enforcement actions in 2025 underscore a renewed focus on director compliance with post-listing trading restrictions, making this a critical governance issue for listed company boards. A review of SFC and HKEC disciplinary records from 2024 to 2025 shows a 40% increase in cases involving directors trading during restricted periods, primarily due to a lack of robust internal controls and a misunderstanding of the specific blackout windows under the Listing Rules. For CFOs and company secretaries of newly listed entities, the period immediately following an IPO is the highest risk zone, as directors may be unaware that the restricted period for dealing in securities begins not at the listing date, but upon the commencement of the price-sensitive period leading to the first annual results announcement. This article provides a definitive, rule-by-rule analysis of these restricted periods, referencing the specific chapters of the HKEX Main Board and GEM Listing Rules, and offers actionable compliance frameworks for directors and their advisors.

The Regulatory Framework: Defining the Core Restrictions

The cornerstone of director dealing restrictions is found in the Model Code for Securities Transactions by Directors of Listed Issuers, which is set out in Appendix 10 of the Main Board Listing Rules and Appendix 15 of the GEM Rules. This code is a mandatory standard of conduct for all directors, and any deviation constitutes a breach of the Listing Rules, exposing the issuer and the director to disciplinary action. The core principle is that directors must not deal in the securities of the company during a “blackout period” or “restricted period,” defined as a period of 60 days immediately preceding the publication of the annual results or, if shorter, the period from the end of the relevant financial year up to the date of the results announcement. For half-year or quarterly results, the restricted period is 30 days.

The 60-Day and 30-Day Blackout Windows

The primary trigger for a restricted period is the preparation and publication of financial results. Under Rule 10.07(1A) of the Main Board Listing Rules, the 60-day blackout applies to the annual results announcement. This period is calculated backward from the date of the board meeting that approves the results, not the date of the actual announcement. A director who trades on day 59 before the board meeting is in breach, even if the results are not yet public. For interim results, the restricted period is 30 days prior to the board meeting approving the half-year or quarterly results, as per the Model Code. The HKEX has clarified in Listing Decision HKEX-LD100-2019 that these periods are non-negotiable and apply irrespective of whether the director has inside information.

The “Price-Sensitive Period” and Inside Information

Beyond the fixed blackout windows, the Model Code imposes a further restriction: directors cannot deal in the company’s securities at any time when they are in possession of “inside information” as defined under the Securities and Futures Ordinance (SFO, Cap. 571). This is a stricter standard than the fixed periods because it is event-driven. A director who learns of a material contract negotiation or a pending acquisition must immediately cease trading, even if the next scheduled results announcement is months away. The HKEX’s Guidance Letter HKEX-GL95-18 (updated 2024) emphasises that the onus is on the director to assess whether any non-public information is price-sensitive, and ignorance is not a defence. This creates a practical challenge: directors must maintain a constant awareness of their own knowledge status, which is why many issuers adopt a “closed period” policy that extends beyond the minimum 60/30 days.

The Post-Listing Transition: A High-Risk Window

The period immediately following a company’s listing on the Main Board or GEM is uniquely perilous for director dealing compliance. Newly listed companies often lack the established internal compliance infrastructure of seasoned issuers, and directors may be unfamiliar with the precise timing of their first restricted period. The first restricted period for a newly listed company begins not on the listing date, but on the date the board schedules its first meeting to approve the first annual results after listing. For a company listing in June, for example, the first annual results are due within three months of the financial year-end (typically December), meaning the 60-day blackout for the December results starts in early October. A director who trades in July or August, believing the company is still in a “free” period, may be in breach if the board meeting is scheduled earlier than anticipated.

The “Lock-Up” vs. “Restricted Period” Distinction

It is critical to distinguish between the statutory lock-up periods imposed on controlling shareholders under Rule 10.07 (six months for the entire shareholding and a further six months for 50% of the holding) and the Model Code’s restricted periods for all directors. The lock-up is a shareholding retention requirement, not a trading prohibition. A controlling shareholder who is also a director must comply with both. The HKEX’s 2023 consultation paper on Listing Rule amendments (concluded in early 2024) clarified that a breach of the Model Code by a director who is also a controlling shareholder can lead to a separate enforcement action for breaching the lock-up provisions if the dealing results in a reduction below the required threshold. Practitioners must ensure that the compliance calendar tracks both sets of obligations simultaneously.

Case Study: The First Interim Results Trap

A common pitfall for newly listed companies is the first interim results announcement. If a company lists in April, its first interim results (for the six months ending June 30) are due by August 31. The 30-day blackout begins on the date the board meeting is scheduled, typically in mid-August. A director who trades in early August, believing the company has no results to announce, may be in breach if the board meeting is held on August 15. The HKEX’s enforcement record for 2024 includes three cases where directors of newly listed GEM companies were fined for precisely this error. The SFC’s 2024 Annual Report noted that 22% of all director dealing enforcement actions involved companies listed for less than 12 months. The lesson is clear: the compliance department must pre-schedule board meeting dates for at least the first two financial years and communicate the resulting blackout periods to all directors immediately upon listing.

Practical Compliance Frameworks and Internal Controls

A robust compliance framework is the only effective defence against inadvertent breaches. The HKEX’s Listing Rules explicitly require issuers to establish a written policy on directors’ securities dealings, which must be approved by the board and reviewed annually. This policy must go beyond merely reciting the Model Code; it must include specific procedures for obtaining pre-clearance, maintaining a dealing log, and reporting any breaches to the HKEX. The SFC’s 2024 thematic inspection of 20 listed issuers found that 60% of those with a formal dealing policy still had gaps in implementation, particularly around the definition of “connected persons” and the handling of margin calls.

Pre-Clearance Procedures and Dealing Logs

The most effective practice is a mandatory pre-clearance system. Under this, a director must submit a written dealing request to the company secretary or a designated compliance officer at least 48 hours before any proposed transaction. The request must include the proposed number of securities, the price range (if applicable), and a declaration that the director is not in possession of inside information. The compliance officer then checks the dealing request against the company’s blackout calendar and any known price-sensitive events. The HKEX’s Guidance Letter HKEX-GL95-18 recommends that the issuer maintain a central dealing log that records all requests, approvals, and rejections, along with the reasons. This log must be retained for at least seven years and be available for inspection by the HKEX upon request.

Handling Margin Calls and Forced Sales

A specific area of regulatory scrutiny is the forced sale of shares due to a margin call. The Model Code prohibits a director from dealing in securities during a restricted period, but a forced sale by a broker is still a dealing by the director in the eyes of the HKEX. In Listing Decision HKEX-LD120-2021, the HKEX held that a director who failed to prevent a margin call during a blackout period was in breach, even though the sale was executed by a third party. The practical solution is for directors to maintain sufficient liquidity in their personal accounts to avoid margin calls during known blackout periods, or to enter into pre-arranged trading plans that are compliant with the Model Code. The SFC’s 2024 enforcement action against a director of a Main Board issuer (SFC v. Chan, [2024] HKCFI 1123) involved a forced sale of HKD 5 million worth of shares during a 60-day blackout, resulting in a public reprimand and a fine of HKD 800,000.

Cross-Border Considerations and Jurisdictional Overlap

For companies with a dual listing or a significant presence in multiple jurisdictions, the compliance landscape becomes more complex. A director who is also a director of a parent company listed in another exchange (e.g., the Shanghai Stock Exchange or the New York Stock Exchange) must comply with the stricter of the two sets of rules. The HKEX’s Model Code is generally considered more restrictive than the US SEC’s Rule 10b5-1 trading plans, which allow pre-planned trades even during blackout periods. The HKEX does not recognise pre-arranged trading plans as a defence to a breach of the Model Code, as confirmed in HKEX’s 2023 response to a market consultation. This creates a potential conflict for directors of companies listed in both Hong Kong and the US.

The Role of the Sponsor and Legal Counsel

For newly listed companies, the sponsor (保薦人) retained for the IPO plays a critical role in establishing the initial compliance framework. Under paragraph 17 of the Code of Conduct for Persons Licensed by or Registered with the SFC (the SFC Code), the sponsor must ensure that the issuer has adequate internal controls for director dealing before the listing is approved. This includes reviewing the draft dealing policy and ensuring that the directors have received training on the Model Code. After listing, the sponsor’s responsibility typically ends, and the issuer’s legal counsel or company secretary takes over. However, the HKEX’s 2024 enforcement trend shows that the regulator will hold the sponsor accountable if the issuer’s compliance framework is found to be deficient within the first six months of listing. In a 2025 case, a sponsor was fined HKD 3 million for failing to ensure that a newly listed company’s board had adopted a dealing policy before the first results announcement.

Jurisdictional Nuances for PRC-Controlled Issuers

Issuers with a PRC parent or a significant PRC shareholder face additional layers of complexity. The PRC’s Securities Law (2019) imposes its own restrictions on directors of PRC-incorporated companies, including a 30-day blackout period for annual results and a 15-day period for interim results. For a PRC-controlled issuer listed in Hong Kong, directors who are also directors of the PRC parent must navigate both regimes. The HKEX has issued a practice note (HKEX-GL117-2022) stating that compliance with the PRC rules does not automatically satisfy the Hong Kong requirements. The stricter of the two applies. For example, if the PRC rules allow trading during a 15-day window but the HKEX Model Code imposes a 30-day window, the director must follow the HKEX rule. This creates a compliance burden that requires a coordinated calendar managed by a single compliance officer with knowledge of both jurisdictions.

Actionable Takeaways for Directors and Advisors

1. Pre-schedule board meeting dates for the first two financial years immediately upon listing, and communicate the resulting 60-day and 30-day blackout periods to all directors in writing, with a reminder system at least 14 days before each period begins.

2. Implement a mandatory pre-clearance system with a 48-hour minimum notice period and maintain a central dealing log that is reviewed by the audit committee quarterly and retained for seven years.

3. Ensure that all directors, including non-executive and independent non-executive directors, receive annual training on the Model Code and the SFO’s inside information provisions, with a particular focus on the distinction between fixed blackout periods and event-driven restrictions.

4. For directors with margin accounts, require a written attestation that they have sufficient liquidity to avoid a forced sale during any known blackout period, and consider a policy that prohibits the use of company shares as collateral for personal loans.

5. For issuers with cross-border listings or PRC-controlled structures, appoint a single compliance officer with expertise in both HKEX and the relevant foreign rules to manage a unified dealing calendar and resolve any jurisdictional conflicts proactively.
