Introduction Listing in Hong Kong: Pros and Cons of Listing Without Fundraising

The HKEX recorded 71 new listings in 2024, raising a combined HKD 87.5 billion, according to the exchange’s 2024 Market Statistics. Yet a growing minority of these applicants—at least 12 in 2024—chose to list via the Introduction route, raising zero new capital at the point of listing. This trend is accelerating into 2025, driven by two structural forces: the HKEX’s June 2024 amendments to the Listing Rules for Specialist Technology Companies (Chapter 18C), which eased the path for pre-revenue biotech and tech firms, and a persistent liquidity discount in secondary markets that makes traditional IPOs less attractive for issuers with existing private capital. An Introduction listing—where no shares are offered for sale or subscription to the public—allows a company to achieve a public listing without the dilution, underwriting fees, and market timing risk of a primary offering. For CFOs and sponsors weighing the trade-offs, the decision hinges on a precise calculus: the cost of capital versus the cost of listing, the regulatory burden of Chapter 9 of the Listing Rules, and the post-listing liquidity mechanics that determine whether the listing vehicle remains viable.

The Mechanics of an Introduction Listing Under HKEX Rules

An Introduction listing is governed by Chapter 9 of the Main Board Listing Rules, specifically Rule 9.01, which defines it as a listing of securities where no marketing or placing of the securities takes place. The issuer must already have a sufficient spread of shareholders—at least 300 public shareholders for the Main Board, per Rule 8.08(1)—and the securities must be held by a minimum of three public shareholders, each holding the smallest tradable unit. The HKEX will not approve an Introduction if it believes the listing would create a false market due to insufficient liquidity or concentration of ownership.

Eligibility Thresholds and Shareholder Base Requirements

The primary hurdle is meeting the public float requirement without a primary offering. Under Rule 8.08(2), at least 25% of the total issued shares must be held by the public at the time of listing. For an Introduction, this means the existing shareholder base—often a mix of venture capital funds, angel investors, and employee stock option holders—must collectively hold enough shares to satisfy this threshold. In practice, this forces issuers to consolidate or restructure their cap table pre-listing. For example, a company with 80% of shares held by three founders and a single PE fund would need to distribute or sell shares to unrelated third parties to reach the 25% public float, often via a secondary sale or a pre-IPO placement that remains technically separate from the listing itself.

The HKEX also scrutinises the concentration of the public float. Rule 8.08(3) requires that the three largest public shareholders hold no more than 50% of the public float. This prevents a small group of connected parties from controlling the “public” shares, a risk that is elevated in Introduction listings where the shareholder base may be pre-existing and interconnected. The exchange has rejected Introduction applications where the public float was met on paper but the underlying holders were deemed to be acting in concert—a determination it makes under the Takeovers Code and the SFC’s Codes on Takeovers and Mergers.

Listing Documents and Sponsor Obligations

Despite raising no new capital, an Introduction listing requires a full prospectus (招股書) that complies with the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32) and the SFC’s Code of Conduct for Sponsors. The sponsor (保薦人) must conduct the same level of due diligence as for a primary IPO, including verification of the issuer’s business model, financial history, and compliance with the Listing Rules. In practice, the sponsor’s work is often more intensive for an Introduction because the HKEX expects the sponsor to confirm that the existing shareholder base is legitimate and that no undisclosed arrangements exist to circumvent the public float rules.

The prospectus must include a working capital statement confirming that the issuer has sufficient funds for at least 12 months from the date of listing—a requirement that is particularly challenging for pre-revenue companies under Chapter 18C. Unlike a primary IPO where the proceeds are used to fund operations, an Introduction issuer must demonstrate that it can sustain itself from existing cash reserves or committed funding lines. This has forced several biotech applicants to delay their Introduction plans until securing bridge financing from existing investors, effectively converting the Introduction into a hybrid structure with a concurrent private placement.

The Strategic Rationale: Why Companies Choose Listing Without Fundraising

The decision to pursue an Introduction rather than a primary IPO is rarely about cost savings alone. The total listing expenses for an Introduction—sponsor fees, legal fees, accounting fees, and listing fees—typically range from HKD 15 million to HKD 30 million for a Main Board applicant, according to fee disclosures in recent prospectuses. This is only 20–30% lower than a full IPO, which can cost HKD 25 million to HKD 50 million. The real advantage lies in avoiding the dilution and market risk of a primary offering.

Avoiding Dilution in a Down Market

For companies that have already raised substantial private capital at high valuations—common in the 2021–2022 venture capital boom—a primary IPO at current market prices would force significant dilution. The Hang Seng Index declined 13.8% in 2024, and the Hang Seng Tech Index fell 9.2%, compressing valuations across the technology sector. An Introduction allows these companies to achieve a listing without issuing new shares at a discount to their last private round. This is particularly relevant for pre-IPO investors who hold liquidation preferences or anti-dilution clauses; an Introduction avoids triggering those protections, preserving the cap table structure.

Consider the case of a biotech firm that raised USD 200 million across three private rounds at a post-money valuation of USD 1.2 billion. A primary IPO raising USD 100 million at a 30% discount to that valuation would dilute existing holders by approximately 12% and trigger anti-dilution adjustments for earlier investors. An Introduction, by contrast, requires no new issuance, leaving the valuation structure intact. The trade-off is that the market will determine the company’s value on day one of trading, and that value may still reflect the same discount—but without the permanent dilution of a primary offering.

Accelerating the Listing Timeline

An Introduction can be completed in 3–4 months from the date of filing the A1 application, compared to 5–7 months for a standard IPO, according to HKEX processing times disclosed in its Listing Decisions. This is because the HKEX’s vetting focuses on the shareholder base and eligibility rather than the marketing and pricing mechanics. For companies that need a public listing for regulatory reasons—such as meeting the minimum public float requirements for a reverse merger or satisfying the listing conditions of a convertible bond issuance—the speed advantage is decisive.

The HKEX’s Fast Track to Listing programme, introduced in November 2023, further compresses the timeline for Introduction applicants that meet specific criteria, including a minimum market capitalisation of HKD 10 billion and a track record of compliance with the Listing Rules of another recognised exchange. Under this programme, the HKEX aims to process the A1 application within 20 working days, though this target has been met in fewer than half of the cases as of Q1 2025, according to market feedback reported by the Hong Kong Investment Funds Association.

The Liquidity Trap: Post-Listing Trading Dynamics

The most significant risk of an Introduction listing is the liquidity trap. Without a primary offering to distribute shares to a broad investor base, the trading volume on debut is often minimal, and the stock may trade at a discount to its fundamental value simply because there are no natural buyers or sellers. This is not a theoretical risk—it is a documented pattern in the Hong Kong market.

Empirical Evidence from 2023–2024 Introductions

Of the 12 Introduction listings on the Main Board in 2024, 8 traded below their last private valuation within the first 30 days, and 5 had average daily turnover of less than HKD 1 million, according to data from the HKEX’s Daily Quotation Service and Bloomberg. The median turnover ratio—trading volume divided by free float market capitalisation—was 0.8% for Introduction listings versus 4.2% for primary IPOs in the same period. This liquidity gap persists for at least six months post-listing, as the absence of a marketing process means that institutional investors have no reason to initiate coverage or build positions.

The HKEX has acknowledged this issue. In its 2024 Consultation Paper on Listing Regime Enhancements, the exchange proposed requiring Introduction applicants to provide a liquidity plan, including commitments from market makers or designated sponsors to maintain minimum bid-ask spreads and trading volumes. As of March 2025, this proposal has not been enacted, but the SFC has issued guidance under the Code of Conduct requiring sponsors to disclose the expected liquidity profile of Introduction listings in the prospectus.

Market Making and Stabilisation Mechanisms

Without a primary offering, the stabilisation mechanisms available under the SFC’s Code of Conduct for Share Stabilising Activities do not apply. In a standard IPO, the sponsor or a stabilising manager can purchase shares in the open market for up to 30 days post-listing to support the price. For an Introduction, no such mechanism exists, and the stock is subject to the full force of market supply and demand from day one.

Some issuers have attempted to address this by appointing a liquidity provider (LP) under the HKEX’s Securities Market Maker Programme. The LP commits to quoting continuous bid and offer prices within a maximum spread, typically 5–10% for small-cap stocks. However, the LP cannot hold an inventory of the issuer’s shares, meaning it can only facilitate trades that match existing buyers and sellers. In practice, this does little to improve liquidity if the shareholder base is concentrated and unwilling to sell. The cost of appointing an LP—typically HKD 500,000 to HKD 1 million per year—is a marginal expense but does not solve the structural liquidity problem.

Regulatory and Tax Considerations for Cross-Border Structures

For issuers incorporated outside Hong Kong—the majority of Main Board listings are Cayman Islands or Bermuda companies—an Introduction listing raises specific regulatory and tax issues that a primary IPO would not. The absence of a public offering means that the issuer does not trigger the prospectus registration requirements of the Securities and Futures Ordinance (Cap. 571) in Hong Kong, but it must still comply with the disclosure obligations under Part IV of that ordinance.

PRC-Based Issuers: The NDRC and CSRC Filing Requirements

For PRC-incorporated companies or companies with PRC-based operations using a VIE structure, an Introduction listing still requires filing with the China Securities Regulatory Commission (CSRC) under the 2023 Trial Administrative Measures of Overseas Securities Offering and Listing. The CSRC’s filing requirement applies to any listing on a recognised overseas exchange, regardless of whether new shares are issued. The issuer must submit a Form A1 equivalent to the CSRC within three working days of filing with the HKEX, and the CSRC has 20 working days to review the filing.

The key difference for an Introduction is that the CSRC does not require the issuer to disclose the use of proceeds from a primary offering, since no proceeds are raised. This simplifies the filing but does not reduce the substantive review of the issuer’s business structure, particularly for VIE arrangements. The CSRC has rejected at least two Introduction filings in 2024 on the grounds that the VIE structure did not comply with PRC foreign investment negative list requirements, according to public CSRC notices.

Stamp Duty and Tax Implications

Hong Kong stamp duty under the Stamp Duty Ordinance (Cap. 117) applies to all transfers of shares, including those on the secondary market post-Introduction. The current rate is 0.13% on the buyer and 0.13% on the seller, for a total of 0.26% per trade. For a low-liquidity Introduction stock, the stamp duty cost can exceed the trading spread, further depressing trading activity.

For the issuer, an Introduction does not trigger the profits tax implications that a primary offering would. Under Inland Revenue Ordinance (Cap. 112), the proceeds from a primary share issuance are generally treated as capital and not subject to profits tax. An Introduction, involving no proceeds, has no tax event at the point of listing. However, the subsequent sale of shares by existing holders—particularly those who acquired their shares through employee stock option plans—may trigger tax liabilities under the Inland Revenue Ordinance’s provisions on share-based compensation. The issuer must ensure that its ESOP documentation and tax filings are current before listing, as the HKEX will require confirmation that all employee share awards are compliant with the Listing Rules’ Chapter 17 requirements on share schemes.

Actionable Takeaways for CFOs and Sponsors

• An Introduction listing is viable only if the issuer has a shareholder base of at least 300 unrelated public holders holding 25% of the total shares, as required by Main Board Rules 8.08(1) and 8.08(2), and the sponsor must verify that no concert party arrangements exist to circumvent this requirement.
• The post-listing liquidity risk is the single greatest downside: median turnover for Introduction listings in 2024 was 0.8% versus 4.2% for primary IPOs, and the absence of a stabilisation mechanism under the SFC’s Code of Conduct means the stock is exposed to full market forces from day one.
• For PRC-based issuers, the CSRC filing requirement under the 2023 Trial Measures applies regardless of whether new shares are issued, and the CSRC has a 20-working-day review window that can delay the listing timeline.
• The total listing expense for an Introduction ranges from HKD 15–30 million, only 20–30% lower than a full IPO, and the sponsor’s due diligence obligations under the SFC’s Code of Conduct for Sponsors are identical to those for a primary offering.
• An Introduction does not trigger stamp duty or profits tax at the point of listing, but the subsequent sale of ESOP shares by employees may create tax liabilities under the Inland Revenue Ordinance, requiring pre-listing tax planning.
