Where a holding structure ahead of the Cayman Islands listing or exit stands now

A company preparing for a Hong Kong or US listing, or a trade sale, through a Cayman Islands vehicle faces a question that sits at the intersection of corporate law, tax policy and regulatory scrutiny: does the structure actually work – or does it merely appear to? The chart on paper is the starting point, not the answer. What the underwriters, the exchange, the tax authority and the acquirer's counsel will probe is whether the entities in the chain have genuine economic substance, coherent beneficial-ownership disclosure, and defensible access to the treaty network that the structure is presumed to deliver.

A holding structure ahead of a Cayman Islands listing or exit is governed by the interaction of Cayman Islands corporate law, Hong Kong corporate and tax rules, and – where a Mainland Chinese operating entity sits beneath – PRC regulatory requirements for variable interest entity (VIE) structures and foreign-investment approvals. The combined effect of the Pillar Two minimum-tax rules, the Hong Kong foreign-sourced income exemption (FSIE) regime and tightened beneficial-ownership disclosure requirements means that structures built even five years ago may require material revision before they are fit for a listing process or a clean exit.

This analysis sets out the commercial stakes, the governing instruments, the cross-border interface between Hong Kong and the Cayman Islands, and where, in our read of the current environment, the real risk sits for groups approaching a liquidity event.

What is commercially at stake when the structure is tested

The listing or exit process is the moment a holding structure is stress-tested by parties with adverse interests. An underwriter runs its own legal due diligence. An exchange has listing requirements that reach behind the Cayman issuer to the beneficial owners and the governance of the operating group. A trade acquirer's counsel will probe the tax history of each intermediate entity and the enforceability of key commercial agreements across borders.

For groups with Mainland Chinese operating businesses, the questions are sharper still. The exit route – whether a Hong Kong IPO, a US ADR listing, or a private sale – determines which regulatory approvals are needed, which disclosure obligations apply, and how the proceeds flow back through the structure. Getting any one of those questions wrong delays the timetable and, in an adverse market, can kill the transaction entirely.

In our cross-border practice, we see a consistent pattern. Groups spend years optimising the structure for operational efficiency – minimising inter-company funding costs, managing foreign-exchange exposure, concentrating IP ownership. The listing or sale process then forces a sudden shift: the structure must also be optimised for disclosure, for tax defensibility and for clean title. Those objectives do not always align, and the gap between them is where deal risk accumulates.

What is the practical consequence of a structure that cannot survive that scrutiny? At the less severe end, it means an extended pre-IPO restructuring that delays the listing window. At the more severe end, it means a failed listing, a reduced acquisition multiple, or a post-transaction tax claim that erodes the net proceeds. The stakes are not abstract.

How does the governing framework actually apply across Hong Kong and the Cayman Islands?

The typical structure for a Greater China operating group approaching a listing or exit places a Cayman Islands holding company at the top, with one or more Hong Kong intermediate holding companies sitting above the operating entities – which may be PRC foreign-invested enterprises, wholly foreign-owned enterprises (WFOEs) or, in restricted sectors, VIE structures. Each layer is governed by a different legal regime, and the interaction between those regimes is where the structure's integrity is tested.

At the Cayman level, the vehicle is incorporated under the Cayman Islands Companies Act. The Cayman Islands have no corporate income tax, no capital gains tax, and no dividend withholding tax. That is the fiscal attraction. The Cayman Islands also impose an economic-substance regime, which requires certain categories of entity carrying on relevant activities to demonstrate genuine substance in the islands. For a pure holding company that does nothing other than hold shares, the substance requirement is lighter – but it is not absent. The company must be managed and controlled in the Cayman Islands in a meaningful sense. Directors' meetings held in name only, without genuine deliberation, will not satisfy the test.

At the Hong Kong intermediate level, the entities are subject to the Companies Ordinance (Cap. 622) and to Hong Kong profits tax under the Inland Revenue Ordinance. Hong Kong's territorial tax system taxes only Hong Kong-sourced profits. Dividends received from subsidiaries are not subject to profits tax as a matter of general principle. However, the FSIE regime – in force from 1 January 2023 and subsequently amended – now requires Hong Kong entities that receive specified types of foreign-sourced income (including dividends from non-Hong Kong subsidiaries and interest) to demonstrate economic substance in Hong Kong, participation in an ownership chain with sufficient nexus, or to be subject to tax elsewhere, in order to maintain the exemption. An intermediate holding entity that is a shell – registered in Hong Kong but without genuine activity, employees or decision-making – faces a real risk that its passive income receipts are brought into charge.

The Pillar Two global minimum-tax rules add a further layer. For multinational enterprise (MNE) groups with consolidated revenue at or above EUR 750 million, Hong Kong's minimum top-up tax and income-inclusion rule apply for fiscal years beginning on or after 1 January 2025. Groups at that scale must model the effective-tax-rate position of each jurisdiction in the chain. A Cayman holding company with no local tax will, in the relevant computation, typically produce a low effective rate – which triggers a top-up charge collected at another group level, most likely the ultimate parent's jurisdiction.

The PRC layer introduces its own set of constraints: approval requirements for inbound and outbound investment flows, foreign-exchange controls administered by the State Administration of Foreign Exchange, and – where a VIE is in play – the continuing legal uncertainty around the enforceability of the contractual arrangements that constitute the VIE structure.

The cross-border interface: where the Cayman Islands and Hong Kong meet in practice

The Cayman Islands and Hong Kong do not have a bilateral tax treaty. That absence is important and is frequently underestimated by groups focused on the headline tax rates. Treaty access, where it matters – for example, on withholding taxes on dividends paid from a PRC operating entity upward through the structure – depends on the treaty network of the intermediate holding company, not the Cayman issuer at the top.

China has an arrangement for the avoidance of double taxation with Hong Kong. That arrangement provides for a reduced withholding-tax rate on dividends paid from a PRC company to a Hong Kong holding company, subject to conditions. The key condition is that the Hong Kong entity must be the beneficial owner of the dividend – a concept that PRC tax authorities have interpreted with increasing rigour over the past decade. A Hong Kong holding company that acts merely as a conduit – passing dividend income straight through to the Cayman parent without genuine economic substance or decision-making – risks being denied beneficial-owner status. The consequence is that the full withholding-tax rate applies, rather than the reduced arrangement rate.

How is beneficial ownership assessed in practice? The PRC tax authority looks at a combination of factors: whether the Hong Kong entity has genuine employees and operating costs; whether its management genuinely makes decisions about the income it receives; whether it has uses for that income other than passing it to the parent; and whether it bears real economic risk. A Hong Kong entity that scores poorly on each of those factors will not be treated as the beneficial owner, regardless of what the corporate chart says.

For groups with a Mainland operating entity beneath the Hong Kong intermediate, the sequence of cash flows at exit also matters. Dividend upstreaming from the PRC to Hong Kong and then to the Cayman parent triggers the withholding-tax question at the PRC–Hong Kong step. A sale of the Cayman holding company by its shareholders does not, in principle, trigger PRC tax – but if the Cayman company is treated as a resident enterprise of the PRC for tax purposes, or if the indirect-transfer rules apply to treat the disposal as a disposal of underlying PRC assets, the position changes. Those rules have broad application and groups should not assume that a clean offshore sale insulates the transaction from PRC tax entirely.

The Hong Kong courts sit within the common-law system. English is an official working language. The Court of First Instance and, on appeal, the Court of Final Appeal provide a well-regarded judicial forum for commercial disputes, and Hong Kong arbitration awards from HKIAC-administered proceedings carry strong enforceability credentials internationally and across the Mainland under the mutual-enforcement arrangements in place since 1999 and the 2020 Supplemental Arrangement. Where a dispute arises within the holding chain – between shareholders, between the Cayman parent and a Hong Kong intermediate, or between the group and a PRC counterparty – the choice of forum and law in the key transaction documents materially affects the enforceability of any resolution.

Substance, beneficial ownership, and what the diligence process actually finds

In our experience of acting on pre-IPO and pre-sale restructurings, the two questions that consistently generate the most difficulty are substance and beneficial ownership. They are related but distinct.

Substance is the question of whether the entities in the chain do anything real – whether they have employees, offices, decision-making, costs and activities proportionate to the role they are described as playing in the group. The Cayman Islands economic-substance rules, the Hong Kong FSIE substance conditions, and the beneficial-ownership test under the PRC–Hong Kong double-tax arrangement all require substance, but each applies different tests. A structure can be technically compliant with one regime while failing another.

Beneficial ownership is the question of who ultimately owns and controls the assets and income flows – and whether the disclosure of that ownership across multiple regulatory regimes is consistent and accurate. Hong Kong companies have been required to maintain a Significant Controllers Register (SCR) since 1 March 2018 under the Companies Ordinance (Cap. 622). The SCR must identify every individual who ultimately owns or controls more than the relevant threshold of shares or voting rights, directly or indirectly. For groups with complex trust structures, nominee arrangements or multiple layers of intermediate holding entities, compiling an accurate SCR and keeping it current is not a trivial exercise.

The listing process amplifies the stakes. An exchange's listing rules require disclosure of beneficial ownership above specified thresholds, and any inconsistency between the SCR, the prospectus disclosure and the actual ownership chain will be identified by the exchange's review team and the underwriters' legal due diligence. A mismatch – even one that arose from an inadvertent failure to update the register following a prior restructuring – can require remediation that delays the listing and creates uncertainty about the integrity of the offering documents.

Consider a practical illustration. A technology group incorporated in the Cayman Islands, with a Hong Kong intermediate holdco and a WFOE operating entity in the Mainland, approached a listing process in the second half of 2025. The Hong Kong intermediate had been dormant in terms of local staffing for several years – its functions had been consolidated into the operating entity below. The FSIE analysis revealed that dividend income received at the Hong Kong level from the WFOE could not satisfy the substance conditions in Hong Kong. A restructuring was required before the prospectus could be filed, adding several months to the timetable and requiring fresh opinion letters from counsel in multiple jurisdictions. The issue was not the structure's legality; it was its fitness for the disclosure and tax-compliance environment of a public-company listing process.

The Significant Controllers Register, the FSIE economic-substance conditions, and the PRC beneficial-owner test each require a clear, consistent and accurate account of who owns what and on what terms. Where those accounts diverge – even technically – the listing or exit is at risk.

The VIE question: a structure that the market depends on and regulators have never fully blessed

For groups in restricted sectors of the PRC economy – technology, education, media and others – the variable interest entity structure remains the dominant mechanism for offshore listing. The VIE uses a series of contractual arrangements between a WFOE and a PRC domestic entity to give the offshore holding company effective economic interest and control, without technically holding equity in the domestic entity that would otherwise be restricted.

The structure has existed for decades and underpins a large proportion of the Greater China offshore-listed universe. It has never been explicitly authorised by PRC law. It rests on the premise that the contractual arrangements are enforceable and that the PRC domestic entity and its equity holders will not act in a way that defeats the offshore investors' economic interest. Neither premise is guaranteed.

The risk is not new. But the regulatory environment in which VIE-based groups operate has changed materially over recent years. PRC authorities have, in a series of regulatory actions and administrative guidance documents, signalled closer scrutiny of offshore listings by PRC-based groups, the use of offshore structures to hold PRC assets, and the data-security and national-security implications of listing entities with access to sensitive PRC data on offshore exchanges. Groups using VIE structures must now navigate a pre-approval process for offshore listings involving PRC-based companies, administered by the relevant PRC regulatory authority. The approval requirement adds a step – and a point of regulatory exposure – that was not part of the listing timetable for earlier cohorts of offshore-listed PRC groups.

What does this mean for a group approaching an exit? The VIE structure must be disclosed clearly in the offering documents, and its legal risk must be described accurately. The contractual arrangements must be reviewed for their continued enforceability. The approval position must be assessed and, where required, the application made and resolved before the listing process can proceed. Each of those steps takes time and requires co-ordination between counsel in Hong Kong, the Cayman Islands and the Mainland.

For a trade sale rather than a listing, the VIE structure raises a different but equally material question: what exactly is the acquirer buying? The acquirer's counsel will probe the enforceability of the contractual arrangements, the identity and co-operation of the PRC domestic-entity equity holders, and the mechanisms available to the offshore holding company to enforce its economic interest if the domestic arrangement is contested. Those questions are answered by the quality of the contractual documentation and the substance of the relationships it purports to govern, not by the chart on paper.

Our desk regularly advises on the review and renegotiation of VIE contractual arrangements in the context of pre-IPO and pre-sale restructurings. The quality of that documentation – and whether it has been kept current as the group's business has evolved – is often the determinative factor in how quickly a transaction can be structured and disclosed. For further analysis of nominee and beneficial-ownership questions within the holding chain, see our guide to nominee, trustee and beneficial-ownership questions and the related matter note.

Where the risk sits now: our analytical read

The risk environment for holding structures ahead of a Cayman Islands listing or exit has shifted in three distinct ways since 2023, and the direction of travel is toward greater scrutiny, not less.

First, the FSIE regime and Pillar Two have materially raised the bar for intermediate holding entities that claim to benefit from Hong Kong's territorial tax system without genuine Hong Kong substance. Groups that structured on the assumption that a Hong Kong intermediate was a low-cost, no-substance pass-through need to revisit that assumption. The IRD has made clear that the substance conditions are not a formality. For in-scope Pillar Two groups, the minimum-tax analysis adds a further layer that cannot be resolved without a jurisdiction-by-jurisdiction effective-rate computation – a task that requires co-ordination across the tax advisers in each relevant location.

Second, the PRC regulatory environment for offshore listings has become considerably more demanding. The pre-approval requirement for offshore listings by PRC-based companies, the data-security review process for groups handling sensitive PRC data, and the broader scrutiny of offshore structures holding PRC assets all add steps to the pre-listing process. Those steps are not advisory – they are mandatory. A group that reaches the listing documentation stage before engaging with the PRC regulatory approval process will face delay and, potentially, a failed listing.

Third, the beneficial-ownership and transparency requirements across the chain have become more demanding and more consistent in their enforcement. The Cayman Islands, the BVI and Hong Kong each now operate meaningful beneficial-ownership registers or registers of significant controllers. An inconsistency between those registers – which can arise simply from a prior restructuring that was not reflected across all relevant registries – is a diligence finding that requires remediation before a listing or a clean exit can proceed.

The implication, in our read, is that the window between deciding to pursue a listing or exit and the realistic earliest date for execution is longer than many groups assume. Pre-IPO restructuring, FSIE substance remediation, VIE documentation review and PRC regulatory approvals are not parallel processes that can all be run simultaneously from a standing start. Each requires its own timeline, its own counsel, and its own resolution before the next step can be taken.

What does a defensible structure look like in the current environment? It has genuine economic substance at each material level of the chain – not necessarily large, but proportionate and real. Its beneficial-ownership disclosure is consistent across the Cayman, Hong Kong and PRC regulatory registers. Its key commercial agreements – including the VIE contractual arrangements, if applicable – have been reviewed recently and kept current. Its tax position has been modelled under the FSIE regime and, where relevant, under Pillar Two. And its regulatory approval position in the PRC has been assessed and, where required, addressed before the listing process begins.

That description sounds straightforward. In practice, achieving it for a group with a multi-year operating history, multiple rounds of financing, and a complex beneficial-ownership chain is a material exercise. Groups that approach a listing or exit with a structure that has not been maintained to that standard will spend time and resources during the transaction window correcting issues that could have been addressed earlier – and at lower cost.

What foreign counsel and in-house teams consistently underestimate

Several recurring errors appear in the pre-listing or pre-sale files that cross our desk. They are worth naming directly, because they are preventable.

The first is treating the Cayman holding company as the answer rather than the starting point. The Cayman Islands vehicle is a well-tested and widely recognised listing vehicle for Greater China operating groups. But the vehicle itself does not resolve the substance, treaty-access, beneficial-ownership or PRC regulatory questions. Those questions sit in the layers beneath. Counsel focused exclusively on Cayman corporate mechanics – the form of the memorandum and articles, the authorised share capital, the drag-along and tag-along provisions in the shareholders' agreement – may not be well-positioned to analyse the cross-border interface between the Cayman layer and the Hong Kong intermediate or the PRC operating layer.

The second error is assuming that the structure that worked for the last financing round will work for the listing or sale. A financing round involves a sophisticated investor who has negotiated the deal terms and conducted its own diligence. A listing involves a public market, an exchange's review process, and a prospectus that is read by regulators and investors who have not negotiated with the group. The disclosure and compliance bar is materially higher. A structure that a sophisticated investor accepted at Series C may not pass the scrutiny of a listing review.

The third error is underestimating the lead time required for pre-listing remediation. Substance remediation requires genuine operational change – hiring, leasing, shifting decision-making. That cannot be done in weeks. PRC regulatory approvals take the time they take. VIE documentation review, renegotiation and re-execution across multiple parties is not a quick process. Groups that begin the listing preparation process only when they have decided to list will almost certainly encounter timeline pressure from one or more of those issues.

A second micro-scenario illustrates the point from the exit side. A private-equity sponsor holding through a Cayman structure with a Singaporean intermediate and a Hong Kong sub-holdco above a PRC operating group initiated a sale process in early 2025. The acquirer's due diligence identified that the Singaporean intermediate held its shares in the Hong Kong sub-holdco through a nominee arrangement that had not been updated in the Significant Controllers Register of the Hong Kong entity for three years. The SCR discrepancy required remediation, generated a delay, and required fresh legal opinions in Singapore and Hong Kong before the transaction could close. The underlying structure was sound; the documentation maintenance had not kept pace with the group's ownership evolution.

The contextual bridge between analysis and action is direct: the issues described above are identifiable before a listing or sale process begins. A structured pre-listing review – covering substance, beneficial-ownership disclosure, VIE documentation quality and the PRC regulatory approval position – is a better use of time and resources than a mid-transaction remediation exercise conducted under deadline pressure.

If an earlier filing, a prior restructuring, or a stalled regulatory engagement has left an unresolved issue in the holding chain, a second analytical read can identify what was missed and which remediation routes remain available. Write to us at info@lockhartyip.com to discuss.

The objection handled: "our structure was reviewed when we raised"

The most common objection to a pre-listing structural review is that the structure was reviewed – by counsel, by the investor's lawyers, by the relevant advisers – at the time of the last financing. Why does it need to be reviewed again?

The answer is that the regulatory environment has changed materially, and the purpose of the review has changed entirely. The financing review asked whether the structure was legally valid, whether the investor's rights were properly documented, and whether the existing business was being conducted within the permitted parameters of the group's licences and approvals. The listing review asks whether the structure can withstand public disclosure, whether its tax position is defensible under current law (including FSIE and Pillar Two), whether its beneficial-ownership chain is complete and consistent, and whether the PRC regulatory approvals required for the listing have been obtained.

Those are different questions. They require different analysis. And the answers may be different, not because anything wrong was done at the financing stage, but because the law has changed, the group's business has evolved, and the standard applicable to a public-company issuer is higher than the standard applicable to a private company at the point of a financing round.

The FSIE regime came into force on 1 January 2023. Pillar Two applies for fiscal years beginning on or after 1 January 2025. The PRC offshore-listing pre-approval requirement was introduced after many existing structures were established. None of those developments was anticipated when structures built several years ago were first designed. A review conducted at the financing stage – even if it was thorough and competent – could not have accounted for them.

There is also a structural reason why the financing review is an imperfect proxy for the listing review. At the financing stage, the investor's counsel is looking at the structure from the investor's perspective: protecting the investor's rights, ensuring the investment agreement is enforceable, verifying that the group is not in default of any material obligation. The listing review looks at the same structure from the perspective of all prospective public investors, the exchange, and the regulators. The scope of each review is different, and the gaps between them are real.

Practical checklist: assessing a structure before the listing or exit window opens

Groups approaching a potential listing or exit in the next 12 to 24 months should consider a structured pre-event assessment. The following questions frame the key areas.

On substance: does each material entity in the holding chain have genuine economic substance at its level – employees, decision-making, costs, and activities proportionate to its described function? Has the Hong Kong intermediate been assessed against the FSIE substance conditions for each category of income it receives? Is the Cayman holding company managed and controlled in a way that satisfies the Cayman Islands economic-substance regime?

On beneficial ownership: is the Significant Controllers Register of each Hong Kong entity complete, accurate, and current? Does it reflect the current ownership chain, including any changes made in recent financing rounds or restructurings? Is the disclosure consistent with the beneficial-ownership register or equivalent maintained by the Cayman entity and any other intermediate holding company?

On the VIE structure, where applicable: have the contractual arrangements been reviewed recently? Are all parties to those arrangements still the correct parties, given any changes in the group's ownership or management? Have the arrangements been updated to reflect any regulatory changes or guidance issued since they were originally executed? Has the PRC regulatory approval requirement for the proposed listing been assessed and, where required, engaged?

On the tax position: has the FSIE analysis been documented? For in-scope Pillar Two groups, has an effective-rate computation been prepared for each jurisdiction in the chain? Are there outstanding correspondence items with the Inland Revenue Department or any other tax authority that require resolution before a listing or sale?

On the transaction documents: do the key commercial agreements within the holding chain – inter-company loans, IP licences, service agreements – reflect the current state of the business? Are they priced on arm's-length terms that will withstand regulatory and diligence scrutiny? Do the shareholders' agreement and articles of association of the Cayman holding company reflect the current rights of all investors?

None of those questions has a universal answer. Each turns on the specific facts of the group, the jurisdictions engaged, and the current state of the documentation. What the checklist provides is a map of the areas where, in our consistent experience, the issues arise.
