Drag-Along and Tag-Along Rights: Shareholder Exit Mechanism in IPO Candidates

The Hong Kong Stock Exchange’s (HKEX) 2024 consultation paper on GEM reforms, coupled with the SFC’s heightened scrutiny of pre-IPO shareholder arrangements, has placed drag-along and tag-along rights under the spotlight for IPO candidates. These provisions, which govern how majority and minority shareholders exit collectively in a sale transaction, are no longer standard boilerplate; they now face direct examination by the Listing Division and the SFC’s Corporate Finance Division for potential conflicts with the Listing Rules’ cornerstone principles of orderly markets and equal treatment of shareholders. The 2025 issuance of HKEX’s revised Listing Decision LD143-2025, which explicitly addresses the enforceability of drag-along rights against minority shareholders post-listing, has forced sponsors to re-evaluate these clauses in every pre-IPO shareholders’ agreement. For IBD analysts and company secretaries, the shift means that a seemingly routine mechanism can now delay a listing application or trigger a waiver requirement under Rule 2.04 of the Main Board Listing Rules if it creates a “disproportionate” exit advantage for pre-IPO investors.

The Structural Mechanics of Drag-Along and Tag-Along Rights

Drag-along rights compel minority shareholders to join a sale of the company initiated by a majority holder or a specified group of shareholders, typically at the same price and on the same terms. Tag-along rights, conversely, allow minority shareholders to “tag along” in a sale initiated by a majority holder, ensuring they receive the same offer as the selling majority. In the context of a Hong Kong IPO candidate, these rights are almost always embedded in the shareholders’ agreement (SHA) or the articles of association of the Cayman Islands or Bermuda incorporated holding company.

The Drag-Along: Forcing a Sale at the Majority’s Behest

The typical drag-along clause in a Hong Kong IPO candidate’s SHA stipulates that if a designated “drag-along holder” (often a financial sponsor holding 30% or more of the issued shares) receives a bona fide third-party offer for its entire stake, it can compel all other shareholders to sell their shares on identical terms. The trigger threshold is critical: HKEX guidance in LD143-2025 indicates that thresholds below 50% of the issued share capital are presumptively problematic, as they risk forcing a sale on a majority that did not initiate the transaction. The clause must also specify the price mechanism—typically the same price per share as the drag-along holder receives, with no discount for lack of control or illiquidity. From a regulatory perspective, the SFC’s Code on Takeovers and Mergers (Takeovers Code) Rule 2.1 applies if the drag-along triggers a mandatory general offer, a scenario that arises if the buyer’s resulting shareholding crosses the 30% threshold. In practice, most drag-along clauses in IPO candidates include an express carve-out that the mechanism cannot be exercised in a manner that would trigger a mandatory offer under the Takeovers Code without the SFC’s consent.

The Tag-Along: Protecting Minority Exit Parity

Tag-along rights are structured as a negative covenant: the majority seller cannot complete the sale unless the tag-along holder is given the opportunity to sell its shares on the same terms. The typical tag-along clause in Hong Kong-listed company SHAs specifies that the tag-along holder must exercise its right within 15 to 30 business days of receiving a “tag-along notice” from the majority seller. The notice must include the identity of the buyer, the price per share, the number of shares to be sold, and the expected closing date. A key structural nuance is whether the tag-along applies to all shares held by the minority holder or only to a pro-rata portion of its stake. Most Hong Kong IPO candidates adopt a “pro-rata” tag-along, meaning the minority holder can sell the same percentage of its holdings as the majority holder is selling. This avoids a situation where the minority holder sells its entire stake while the majority retains control, which could trigger a change of control event under the Takeovers Code. The SFC’s 2022 guidance note on pre-IPO structures specifically cautions that tag-along rights must not be structured in a way that discriminates between different classes of shareholders, particularly if the IPO candidate has issued preference shares that carry enhanced tag-along rights.

Regulatory Scrutiny and Listing Rule Compliance

The HKEX Listing Rules do not explicitly prohibit drag-along or tag-along rights, but the Listing Division’s practice, as codified in LD143-2025, requires that these provisions be “disapplied” or “suspended” upon listing. The rationale is that once a company is listed, all shareholders trade on the exchange and any forced sale mechanism would contravene the principle of free transferability of shares under Rule 2.03(2). The SFC’s position, articulated in its 2023 “Guidance Note on Pre-IPO Investments and Shareholders’ Agreements,” draws a clear line: any drag-along or tag-along right that remains operative post-listing must be disclosed in the prospectus and must not impair the orderly functioning of the secondary market.

The LD143-2025 Precedent and Sponsor Obligations

LD143-2025, issued in March 2025, arose from a listing application by a pharmaceutical company (the “Applicant”) whose SHA contained a drag-along clause exercisable by a single financial sponsor holding 25% of the pre-IPO shares. The Listing Division held that this clause was “inconsistent with the spirit of the Listing Rules” because it could force a sale of the entire company without the consent of the other 75% of shareholders. The Division required the Applicant to amend the SHA so that the drag-along right would lapse automatically upon listing and could only be reinstated if the company were to be delisted. The precedent is binding on all listing applications filed after 1 June 2025. For sponsors, the obligation under paragraph 17 of the Code of Conduct for Persons Licensed by or Registered with the SFC is to conduct a “reasonable due diligence” review of all pre-IPO SHAs and to flag any drag-along or tag-along clauses that could be deemed “disproportionate” or “oppressive” under HKEX guidance. Failure to do so exposes the sponsor to potential disciplinary action, as seen in the SFC’s 2024 reprimand of a sponsor for failing to identify a tag-along clause that gave preference shareholders a superior exit right over ordinary shareholders.

Disclosure Requirements in the Prospectus

HKEX Listing Rules Appendix 1A, paragraph 27(2) requires that any “material” shareholders’ agreement be disclosed in the prospectus. The Listing Division’s practice is to treat drag-along and tag-along rights as material if they affect more than 10% of the issued share capital at the time of listing. The prospectus must include: (a) the identity of the parties to the agreement; (b) the trigger threshold for the drag-along or tag-along; (c) the price mechanism; (d) whether the rights survive listing; and (e) any waiver or modification obtained from HKEX. The SFC’s 2023 Guidance Note further requires that the prospectus include a risk factor section specifically addressing the potential impact of these rights on minority shareholders post-listing, even if the rights are suspended. For example, if the drag-along right could be reinstated upon a delisting, the prospectus must disclose the circumstances under which delisting could occur and the likely price impact on minority shareholders. In practice, this has led to prospectuses containing 5 to 10 pages of risk factors solely related to pre-IPO shareholder rights, a trend that began with the 2024 wave of GEM listings where such clauses were more prevalent.

Cross-Border Structuring and Tax Implications

For Hong Kong IPO candidates with PRC operating subsidiaries or BVI/Cayman holding structures, the enforceability of drag-along and tag-along rights depends on the governing law of the SHA. Most Hong Kong-listed companies incorporate in the Cayman Islands or Bermuda, and their SHAs are governed by Cayman or Hong Kong law. However, the underlying assets are often in the PRC, which introduces a layer of complexity under PRC Company Law and the PRC Foreign Investment Law.

Cayman Islands and BVI Law Considerations

Under Cayman Islands law, drag-along rights are enforceable provided they are properly drafted and do not constitute a “fraud on the minority” under the common law principle established in Foss v. Harbottle (1843). The Cayman Islands Grand Court in Re CVC/Opportunity Equity Partners (2022) confirmed that a drag-along clause contained in a company’s articles of association is binding on all shareholders, including those who did not vote for it, as long as the clause does not violate the company’s memorandum or the Companies Act (2023 Revision). For BVI companies, the BVI Business Companies Act, 2004 (as amended) provides statutory recognition of drag-along rights in section 59A, which permits a company’s memorandum and articles to include provisions requiring a shareholder to sell its shares if a specified majority of shareholders agrees. The key practical difference is that BVI law requires a higher threshold—typically 75% of the voting shares—for a drag-along to be enforceable against a dissenting shareholder, whereas Cayman law permits a lower threshold if the articles so provide. For Hong Kong IPO candidates, the choice of jurisdiction is often dictated by the sponsor’s preference for the flexibility of Cayman law, which allows drag-along thresholds as low as 50% plus one share, provided the clause is “fair” under the Cayman Islands’ Unfair Prejudice provisions in section 92 of the Companies Act.

PRC Company Law and SAFE Registration

When the Hong Kong-listed company holds its PRC subsidiaries through a VIE structure or a direct Wholly Foreign-Owned Enterprise (WFOE), the drag-along and tag-along rights in the Cayman-level SHA must be mirrored in the PRC-level shareholders’ agreements or the WFOE’s articles of association. The PRC Company Law (2023 Revision, effective 1 July 2024) imposes a statutory pre-emptive right under Article 84: shareholders have the right of first refusal on any transfer of shares by another shareholder. A drag-along clause that overrides this pre-emptive right is enforceable only if all shareholders have expressly waived their pre-emptive rights in writing. The State Administration of Foreign Exchange (SAFE) Circular 37 (2014) also comes into play if the drag-along involves a change in the ultimate beneficial ownership of the PRC entity. In practice, the sponsor’s PRC legal counsel must obtain a written waiver of pre-emptive rights from all PRC-level shareholders before the drag-along can be enforced. Failure to do so creates a risk that the PRC subsidiary’s registration with the Administration for Market Regulation (AMR) could be challenged, potentially delaying the share transfer. For tag-along rights, the PRC Company Law does not provide a statutory equivalent, so the tag-along must be explicitly included in the PRC-level SHA and registered with the AMR to be enforceable against third-party buyers.

Market Practice and Negotiation Dynamics

In the 2025-2026 IPO pipeline, drag-along and tag-along rights have become a key negotiation point between financial sponsors and founder shareholders. Sponsors typically insist on a drag-along right to ensure they can exit their investment in a trade sale without being blocked by a minority founder who may hold a strategic stake. Founders, conversely, demand tag-along rights to prevent the sponsor from selling its stake to a strategic buyer that the founder does not approve of.

The Sponsor’s Perspective: Ensuring Exit Liquidity

For private equity sponsors, the drag-along right is a non-negotiable term in any SHA. The standard market practice for Hong Kong-listed companies is a drag-along threshold of 50% to 66.67% of the issued share capital, with the right lapsing upon listing. However, the sponsor’s legal counsel will often negotiate for the drag-along to be reinstated if the company is subsequently delisted or if the sponsor’s stake falls below a certain threshold (e.g., 10%) due to dilution. The sponsor will also insist on a “no-shop” clause in the SHA that prevents the founder from soliciting alternative buyers during the drag-along process. The 2025 HKEX guidance in LD143-2025 has made it harder for sponsors to include a “double-trigger” drag-along, where the right can be exercised by two or more sponsors acting together, even if individually they hold less than the threshold. The Listing Division views this as a potential circumvention of the spirit of the rule, and sponsors now must seek a specific waiver under Rule 2.04 if they wish to retain such a clause.

The Founder’s Counter: Tag-Along and Pre-Emptive Rights

Founder shareholders in Hong Kong IPO candidates typically negotiate for a tag-along right that covers 100% of their shares, not just a pro-rata portion. This is particularly important in companies where the founder holds a minority stake (e.g., 15% to 25%) after multiple funding rounds. The tag-along right effectively gives the founder a veto over any sale by the sponsor that would leave the founder as a minority shareholder in a company controlled by a new strategic buyer. The founder will also seek a “right of first refusal” (ROFR) on any sale by the sponsor, which gives the founder the option to buy the sponsor’s stake before it is offered to a third party. The interplay between the ROFR, the tag-along, and the drag-along creates a complex negotiation matrix. In the 2025 IPO of a Hong Kong-based biotech company, the founder successfully negotiated a “most-favored-nation” clause in the SHA that required the sponsor to offer the founder the same tag-along terms as any other shareholder, effectively preventing the sponsor from giving a strategic investor a superior exit right. This clause was disclosed in the prospectus and did not raise any objections from the Listing Division, as it did not impair the free transferability of shares post-listing.

Actionable Takeaways for Stakeholders

• Sponsors must review all pre-IPO SHAs against LD143-2025 before filing an A1 application, as any drag-along clause exercisable by a shareholder holding less than 50% of the issued shares will presumptively require a waiver under Listing Rule 2.04.
• Founders should insist on a tag-along right covering 100% of their shares, drafted to survive listing in a suspended form, and ensure the prospectus explicitly states that the right will be reinstated upon any voluntary delisting or privatization.
• Company secretaries must verify that the PRC-level SHAs for WFOE subsidiaries contain a written waiver of pre-emptive rights under PRC Company Law Article 84, registered with the AMR, to prevent enforcement challenges in a drag-along sale.
• IBD analysts evaluating IPO candidates should scrutinize the “material agreements” section of the prospectus for any drag-along or tag-along clauses that deviate from the standard HKEX market practice, as these are red flags for potential post-listing shareholder disputes.
• Cross-border investors holding minority stakes in pre-IPO companies should negotiate for a “most-favored-nation” tag-along clause in the SHA, ensuring their exit terms are no less favorable than those granted to any other shareholder, including financial sponsors.
