This article checks the current HKEX Main Board Chapter 8 and official implementation announcements as at 25 October 2026. It explains document reading, not an individual stock or a new listing event. The general framework below is not a case-eligibility calculator: H shares, A+H issuers, specialist chapters and other share structures require separate review.

Write Down the Question Behind Each Percentage

Public-subscription allocation concerns distribution of offer shares through a particular channel. Public float concerns holdings recognised as public under the rules. Free float adds a check on availability for trading at listing. These measures are not interchangeable simply because each relates to the public. HKEX IPO and open-market implementation announcement

Measure Main question Common confusion
Public-subscription allocation How are offer shares allocated to that subscription channel? Treating it as a percentage of all issued shares
Initial public float Which shares count as being in public hands? Assuming every such share can immediately be sold
Initial free float How many publicly held shares are available for trading? Ignoring contractual, regulatory or legal restrictions
Ongoing public float Are post-listing requirements and disclosures met? Reusing a one-off listing calculation mechanically

This is a reading sequence, not a complete legal-definition table. Apply the relevant chapters and formal prospectus with professional review rather than deriving every condition from a news headline's percentage.

Being Outside the Company Does Not Settle Public Status

Main Board Rule 8.24 excludes core connected persons and identifies other cases involving financing of acquisitions by the issuer or relevant persons, and following their instructions on the disposition of shares. A different name or no employment relationship with the issuer does not independently establish public status. Chapter 8 PDF obtained from the current Main Board directory

Internal preparation should therefore go beyond shareholder names and quantities. It should explain relationships, subscription funding, agreements and control arrangements. This is a record-preparation suggestion, not an instruction for founders to classify shareholders themselves. Refer uncertain relationships to the sponsor and legal advisers.

Similarly, placing shares in a trust, employee arrangement or another holding entity does not automatically resolve the rules' treatment. Read the arrangement and applicable provisions rather than relying on a registration record or abbreviated label.

Free Float Requires a Further Restriction Check

The general framework in current Rule 8.08A addresses shares in public hands without disposal restrictions, whether contractual, under the Listing Rules, applicable law or otherwise. The general paths are at least 10% of the relevant issued class with an expected value of at least HK$50 million at listing, or expected free-float value of at least HK$600 million. The relevant denominator excludes treasury shares. Main Board open-market and free-float rules

Keep the “and” and “or” distinct. The value concerns the relevant portion of shares, not the entire company's valuation or cash raised. Initial public float under Rule 8.08 also uses tiers based on the expected value of the relevant class; 25% is not a universal sole threshold for every applicant.

Shares without disposal restrictions are not necessarily available for trading in every arrangement. The rules include further detail, and specialist structures and chapters may impose different requirements. This article does not apply the general figures indiscriminately to biotech, specialist-technology or other applicants.

An Illustrative Calculation Reveals the Denominators

Assume a class has 100 million issued shares at listing. Suppose 25 million count as publicly held under the applicable rules and 10 million of those are restricted. For illustration only, assume the remaining 15 million are actually available for trading: public float is 25%, while the simplified free-float percentage is 15%.

Now assume the offering comprises 10 million shares, with two million allocated to public subscription. Two million divided by the 10 million offered is 20%; divided by the class's 100 million issued shares it is 2%. “20% allocated to public subscription” therefore does not mean the public holds 20% of the issuer.

These are hypothetical analytical numbers, not a real offering. They do not assess valuation, holder spread, concentration, special rules or other conditions, and cannot establish listing eligibility. Their purpose is to encourage a numerator, denominator and information date beside every percentage.

Put Lock-Ups and Ongoing Requirements on Separate Timelines

Cornerstone and other arrangements can involve lock-ups. The investor label alone should not determine public status or tradability. Align agreements, disclosures, restrictions and dates; expiry does not establish that an investor will actually sell. Our guide to cornerstone versus pre-IPO share investment addresses the transaction distinction.

There is also a post-listing public-float regime. HKEX's announcement of 17 December 2025 introduced amendments effective 1 January 2026, replacing transitional arrangements. Do not merge an earlier consultation proposal, initial requirements and continuing requirements into one table. Ongoing public-float announcement

For GBA teams still raising early-stage capital, the immediate work is maintaining a continuous record of equity, payments and rights, not describing a funding round as having “met IPO float standards”. Actual offering structures and rule applications belong with the appropriate professionals.
