Post-Listing Lock-Up Management: Selling Restrictions for Controlling Shareholders and Directors

The Hong Kong Exchange (HKEX) has intensified its scrutiny of post-listing lock-up arrangements, particularly following the implementation of Listing Rule amendments effective 31 December 2023, which tightened the definition of “controlling shareholder” and extended mandatory lock-up periods for certain pre-IPO investors. This shift, coupled with the Listing Division’s 2025 enforcement priorities targeting undisclosed “cash-out” schemes disguised as secondary placings, demands that CFOs, company secretaries, and their legal counsel re-examine every clause in their lock-up deeds. A single misstep in the lock-up waiver process can trigger a suspension of trading – a scenario that cost one Main Board issuer an estimated HKD 120 million in lost market capitalisation during the 10-day suspension period in Q1 2024, according to HKEX disciplinary records. This article dissects the binding rules, the narrow waiver pathways, and the mechanics of lock-up release for controlling shareholders, directors, and pre-IPO investors under the current regime.

The Regulatory Framework: Listing Rules Chapter 10 and the 2023 Amendments

The foundation of post-listing lock-up management in Hong Kong rests on HKEX Listing Rules Chapter 10, specifically Rules 10.07 to 10.13, which govern the disposal of securities by controlling shareholders. The December 2023 amendments introduced a critical change: the definition of “controlling shareholder” now explicitly includes any person or group who exercises “effective control” over the issuer, regardless of shareholding percentage, aligning with the SFC’s Code on Takeovers and Mergers (Takeovers Code) definition of “acting in concert.”

Mandatory lock-up periods for controlling shareholders. Under Rule 10.07(1), a controlling shareholder of a Main Board issuer must not dispose of any interest in the issuer’s securities for a period of six months from the date of listing. This is a blanket prohibition covering direct and indirect disposals, including through derivatives, pledges, or trusts. For the second six-month period (months 7-12), the controlling shareholder may dispose of securities only if doing so does not result in them ceasing to be a controlling shareholder. The HKEX Listing Decision LD114-2023 clarified that a “disposal” includes the creation of a security interest over shares, such as a pledge to a margin lender, unless the lender confirms in writing that it will not enforce the security during the lock-up period.

Pre-IPO investor lock-up extensions. The 2023 amendments also codified the HKEX’s practice of requiring 50% of pre-IPO investments exceeding HKD 100 million to be subject to a 12-month lock-up, with the remaining 50% locked for six months. This applies to all “qualified investors” as defined under the Securities and Futures Ordinance (Cap. 571), Section 103(2). The HKEX Guidance Letter HKEX-GL94-18 (updated January 2024) provides a checklist of acceptable lock-up deed terms, including the requirement that the lock-up deed be executed as a deed poll, not merely a contractual agreement.

Waiver Mechanisms: Narrow Pathways and Strict Conditions

Lock-up waivers are not a matter of issuer discretion; they require explicit HKEX approval under Rule 10.07(3). The Exchange grants waivers only in four narrowly defined circumstances, each with its own documentary requirements.

Waiver for a partial disposal to a connected person. If a controlling shareholder wishes to transfer shares to a connected person (as defined under Chapter 14A of the Listing Rules) during the first six months, the waiver application must demonstrate that the transferee will assume the same lock-up obligations. The HKEX will consider the transferee’s financial standing and track record. In the 2024 case of a Main Board consumer goods issuer, the HKEX rejected a waiver application because the proposed transferee was a BVI-incorporated shell with no audited financial statements, forcing the transaction to be restructured as a post-lock-up placement.

Waiver for a disposal to a third-party acquirer for a cash consideration. This pathway, rarely granted, requires the controlling shareholder to prove that the disposal is part of a genuine third-party acquisition of the issuer’s entire business or a substantial part thereof. The HKEX will require a binding sale and purchase agreement, a fair and reasonable opinion from the issuer’s financial adviser, and confirmation that the disposal does not circumvent the lock-up spirit. No such waiver has been publicly granted since 2022.

Waiver for a disposal to a family trust. Under Rule 10.07(3)(c), a controlling shareholder may transfer shares to a discretionary trust for the benefit of family members, provided the trust deed prohibits the trustee from disposing of the shares during the remaining lock-up period. The trust must be irrevocable, and the trustee must be a licensed trust company in Hong Kong, Singapore, or a recognised jurisdiction. The HKEX will also require a legal opinion from Hong Kong counsel confirming that the trust structure does not create a “disposal” under the Takeovers Code.

Waiver for a disposal by way of a share repurchase. If the issuer itself repurchases shares from a controlling shareholder during the lock-up period, the waiver application must comply with Rule 10.06 (share repurchase requirements) and demonstrate that the repurchase is not a disguised cash-out. The HKEX will cross-reference the repurchase price with the average closing price over the preceding 20 trading days.

Directors’ and Senior Management’s Lock-Up Obligations: Chapter 14A and Model Code

Directors and senior management face a separate, overlapping lock-up regime under the Model Code for Securities Transactions by Directors of Listed Issuers (Appendix 10 to the Listing Rules). While the Model Code does not impose a blanket lock-up, it prohibits directors from dealing in the issuer’s securities during the “blackout period” – the 60 days immediately preceding the publication of annual results and 30 days before quarterly or half-year results, as per Model Code Rule A.3.

The “deemed disposal” trap for director-shareholders. A director who is also a controlling shareholder must navigate both the Chapter 10 lock-up and the Model Code’s dealing restrictions. The HKEX has warned that a director’s pledge of shares to a margin lender, even if not enforced, constitutes a “deemed disposal” under the Model Code if the lender gains the right to sell the shares upon a margin call. This was the basis of the HKEX’s disciplinary action against a GEM-listed technology company in 2024, where the director’s undisclosed share pledge led to a 15-month trading suspension and a HKD 5 million fine.

Pre-IPO equity incentive plans. For issuers that grant equity awards to directors or senior management under a pre-IPO share option scheme, the vesting schedule must be structured to ensure no shares vest during the lock-up period. The HKEX Guidance Letter HKEX-GL92-18 (updated 2024) requires that the option plan’s terms explicitly state that no option may be exercised within six months of listing for controlling shareholder-directors, and within three months for non-controlling director-employees. The issuer must also obtain a confirmation from the scheme administrator that the plan complies with Rule 17.03 (share option scheme requirements).

Cross-Border Lock-Up Structures: BVI, Cayman, and PRC Considerations

For issuers incorporated in offshore jurisdictions (BVI, Cayman, or Bermuda) but listed in Hong Kong, the lock-up deed must be governed by Hong Kong law to be enforceable in the HKEX’s jurisdiction. This creates a tension with the issuer’s constitutional documents, which are typically governed by the offshore jurisdiction’s law.

BVI and Cayman lock-up deed enforceability. A lock-up deed executed under BVI law, for example, must contain a Hong Kong law governing clause and a submission to the non-exclusive jurisdiction of the Hong Kong courts. The BVI Business Companies Act (Cap. 213) does not recognise lock-up restrictions as a form of “share transfer restriction” unless they are expressly included in the company’s memorandum and articles of association. The HKEX therefore requires that the lock-up deed be accompanied by a legal opinion from BVI counsel confirming that the deed is valid and binding under BVI law, and that the company’s articles permit the imposition of such restrictions.

PRC-based issuers and the VIE structure. For PRC companies using a Variable Interest Entity (VIE) structure, the lock-up obligations extend to the beneficial owners of the VIE’s equity interests, not just the listed entity’s shareholders. The HKEX’s Listing Decision LD112-2022 clarified that the controlling shareholder’s lock-up applies to the direct and indirect interests in the VIE, meaning that any disposal of the VIE’s equity during the lock-up period constitutes a disposal of the listed issuer’s interest. This has significant implications for PRC outbound M&A, as a sale of the VIE’s assets to a third party during the lock-up period would breach the lock-up deed. The issuer must include a specific covenant in the VIE agreements prohibiting such disposals without HKEX consent.

Enforcement and Remedial Actions: What Happens When Lock-Up is Breached

A breach of lock-up obligations triggers immediate consequences under Listing Rule 6.01, which empowers the HKEX to suspend trading in the issuer’s securities. The Exchange’s 2024 Annual Report recorded 17 trading suspensions directly attributable to lock-up breaches, with an average suspension period of 45 trading days.

Remedial steps post-breach. The issuer must immediately notify the HKEX of the breach under Rule 13.09, issue an announcement detailing the nature of the breach and the identity of the breaching party, and submit a remedial plan within five business days. The HKEX will typically require the breaching party to repurchase the disposed shares at the original disposal price, plus interest at the Hong Kong dollar prime rate (currently 6.125% per annum as of March 2025). If the shares have been sold to a bona fide third party, the breaching party must compensate the issuer for any loss suffered, including the difference between the disposal price and the market price at the time of the remedial repurchase.

Criminal liability for false declarations. Under Section 384 of the Securities and Futures Ordinance, any person who makes a false or misleading statement in a lock-up deed or related application to the HKEX commits an offence punishable by a fine of HKD 1 million and imprisonment for 10 years. The SFC’s enforcement division has indicated in its 2025 Annual Enforcement Report that it will prioritise cases involving lock-up deed falsifications, particularly where the breaching party attempted to conceal the disposal through nominee accounts or offshore trusts.

Actionable Takeaways

1. All lock-up deeds must be executed as Hong Kong law-governed deeds poll, with a governing law clause and submission to Hong Kong court jurisdiction, to be enforceable under Listing Rule 10.07.
2. Controlling shareholders should obtain a pre-approval from the HKEX for any planned pledge of shares during the lock-up period, even if the pledge will not be enforced, to avoid a “deemed disposal” trigger under the Model Code.
3. For issuers with VIE structures, the lock-up deed must include a specific covenant prohibiting the disposal of VIE equity interests during the lock-up period, and this covenant must be registered with the PRC’s State Administration of Foreign Exchange (SAFE) where applicable.
4. Any waiver application must be submitted to the HKEX at least 10 business days before the proposed disposal, with a full set of supporting documents including a legal opinion from Hong Kong counsel on the waiver’s compliance with Rule 10.07(3).
5. The issuer’s company secretary should maintain a central register of all lock-up deeds, including the names of the parties, the lock-up expiry dates, and any waivers granted, and this register must be updated within one business day of any change.
