How to Build a Red Chip Structure for a Hong Kong IPO: A Three-Step Guide

The 2025 iteration of the Hong Kong IPO market has seen a decisive shift in issuer domicile strategy. Data from the Hong Kong Stock Exchange (HKEX) shows that of the 73 new Main Board listings in the first nine months of 2025, 62 — or 84.9% — were structured as offshore holding companies incorporated in the Cayman Islands, with the underlying PRC operating assets held through a web of Hong Kong and BVI subsidiaries. This is not a stylistic preference; it is a direct response to the tightening of the PRC’s cross-border data security regime and the evolving stance of the China Securities Regulatory Commission (CSRC) on offshore listings. The traditional “red chip” structure, where a PRC domestic entity is controlled by an offshore vehicle, remains the dominant architecture for Chinese enterprises seeking a Hong Kong listing, but the specific mechanics of building one have become more complex since the CSRC’s Trial Administrative Measures of Overseas Securities Offering and Listing (CSRC Decree No. 43) came into full effect on March 31, 2023. Any issuer or sponsor failing to understand the three-step sequence — offshore vehicle formation, onshore VIE/WFOE assembly, and regulatory filing — risks a rejection at the listing committee stage.

Step One: Constructing the Offshore Holding Chain

The foundational layer of any red chip structure is a tiered offshore holding chain designed for tax efficiency and regulatory compliance. The standard architecture begins with a Cayman Islands exempted company as the ultimate listed issuer. This entity is 100% owned by the pre-IPO shareholders, typically through a BVI holding company for each founding shareholder or investor group. The use of BVI vehicles is not arbitrary: the BVI Business Companies Act, 2004 (as amended) provides for zero capital gains tax, no stamp duty on share transfers, and the ability to issue shares without par value, all of which are critical for future M&A and employee share option schemes (ESOPs).

Below the Cayman issuer sits a Hong Kong-incorporated special purpose vehicle (SPV). This Hong Kong company is the direct wholly-owned subsidiary of the Cayman issuer and serves as the primary conduit for repatriating profits from the PRC. The Hong Kong company benefits from the double tax treaty between Hong Kong and the PRC (the Arrangement between the Mainland of China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation on Income, signed in 2006, as amended). Under this treaty, withholding tax on dividends paid from a PRC subsidiary to its Hong Kong parent is capped at 5%, provided the Hong Kong company holds at least 25% of the PRC entity’s equity. Without this structure, the standard PRC withholding tax on outbound dividends is 10%.

The final offshore layer is typically a BVI or Hong Kong company that directly owns the equity in the PRC operating entity or the onshore WFOE (Wholly Foreign-Owned Enterprise). The choice between BVI and Hong Kong at this level depends on whether the issuer intends to use a direct equity structure or a Variable Interest Entity (VIE) structure. For industries where foreign ownership is unrestricted — such as manufacturing or retail — the Hong Kong SPV can directly hold equity in a PRC WFOE. For restricted sectors such as value-added telecommunications, internet content provision, or education, a VIE structure is mandatory, and the offshore entity will instead hold the equity of a PRC WFOE that has contractual control over the operating company.

Step Two: Assembling the Onshore PRC Entity and VIE Architecture

Once the offshore chain is established, the issuer must create the onshore PRC legal entities that will actually conduct the business and hold the assets. The typical structure involves a Wholly Foreign-Owned Enterprise (WFOE) registered in the PRC under the Foreign Investment Law of the PRC (effective January 1, 2020). The WFOE is 100% owned by the Hong Kong SPV and is capitalised with registered capital that must be fully paid in within the timeframe specified in its articles of association — commonly 3 to 5 years. The WFOE’s business scope must be carefully drafted to match the permitted foreign investment categories under the Special Administrative Measures (Negative List) for Foreign Investment Access (2024 edition). Any activity not on the negative list is presumed open to foreign investment, but the WFOE must still obtain all necessary operating licences.

For issuers in restricted sectors, the WFOE cannot directly own the operating company. Instead, a VIE structure is employed. Under this arrangement, the PRC operating company (the “OpCo”) is 100% owned by PRC nationals — typically the founders. The WFOE then enters into a series of contractual agreements with the OpCo and its shareholders. The core agreements are: (1) an Exclusive Call Option Agreement, granting the WFOE the right to purchase all equity in the OpCo at nominal consideration upon exercise; (2) a Share Pledge Agreement, under which the OpCo’s equity is pledged to the WFOE as security; (3) a Power of Attorney, by which the OpCo shareholders grant the WFOE voting rights over their shares; and (4) an Exclusive Technical Services Agreement, under which the OpCo pays substantially all of its profits to the WFOE as service fees.

The CSRC has formally acknowledged the VIE structure in its Decree No. 43 filing requirements. As of 2024, any issuer using a VIE must disclose in its prospectus the specific risks of the structure, including the potential for PRC regulatory authorities to invalidate the contractual arrangements. The HKEX Listing Rules (specifically Chapter 19C for overseas issuers and Guidance Letter HKEX-GL94-18) require the sponsor to confirm that the VIE structure is “legally enforceable” under PRC law. This is a high bar: the sponsor must obtain a PRC legal opinion from a qualified law firm confirming that the structure does not violate the Negative List or any sector-specific regulations.

Step Three: Navigating the Dual Regulatory Filing Regime

The final and most time-sensitive step is the dual filing with the CSRC in Beijing and the HKEX in Hong Kong. Since March 31, 2023, all PRC companies seeking an overseas listing — including red chip structures where the issuer is incorporated offshore but the operating business is in the PRC — must file with the CSRC under Decree No. 43. The filing must be submitted within three business days of the HKEX’s acceptance of the listing application (the A1 submission). The CSRC requires a comprehensive filing package that includes: (1) the issuer’s prospectus draft; (2) the VIE contractual agreements (if applicable); (3) a legal opinion from PRC counsel confirming compliance with all applicable laws; and (4) a data security self-assessment report, as mandated by the PRC Data Security Law (effective September 1, 2021) and the Personal Information Protection Law (effective November 1, 2021).

The CSRC review period is 20 working days for a standard filing, but if the regulator raises questions, the clock stops until the issuer responds. Data from the CSRC’s public filing list shows that as of September 2025, the average review time for red chip structures with VIE components was 47 calendar days, compared to 29 calendar days for direct equity structures. This discrepancy reflects the additional scrutiny applied to VIE arrangements, particularly in sectors involving user data.

Concurrently, the issuer must satisfy the HKEX’s listing requirements under the Main Board Listing Rules. Rule 8.05 requires a profit test of at least HKD 35 million in the most recent year and HKD 45 million in the two preceding years. For issuers that do not meet the profit test, the market capitalisation/revenue test under Rule 8.06 requires a market cap of at least HKD 4 billion and revenue of at least HKD 500 million in the most recent year. The sponsor must also conduct a robust due diligence exercise under the SFC’s Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (Chapter 17), which requires the sponsor to verify the legal ownership of the PRC operating assets, the validity of the VIE agreements, and the absence of any PRC regulatory violations.

Closing: Five Actionable Takeaways for Issuers and Sponsors

1. Start the CSRC filing process at least 12 weeks before the planned A1 submission, as the average review time for VIE structures is 47 calendar days, and any deficiency notice will add weeks to the timeline.

2. Ensure the Hong Kong SPV holds at least 25% equity in the PRC WFOE to qualify for the reduced 5% withholding tax rate under the Hong Kong-PRC double tax treaty, otherwise the standard 10% rate will apply on all profit repatriation.

3. Obtain a PRC legal opinion that explicitly confirms the enforceability of all VIE contractual agreements under PRC law, as the HKEX will reject any listing where the sponsor cannot provide this confirmation under Guidance Letter HKEX-GL94-18.

4. Conduct a data security self-assessment and file it with the CSRC as part of the Decree No. 43 package, because failure to comply with the PRC Data Security Law can result in a suspension of the listing application.

5. Structure the pre-IPO investor holdings through BVI vehicles rather than direct Cayman shareholding, as this allows for tax-free share transfers and simplifies the implementation of ESOPs without triggering stamp duty in Hong Kong or the Cayman Islands.
