Hong KongHong Kong Listing Rules: the basics for Paper 1
The Listing Rules are made and enforced by the Stock Exchange of Hong Kong, not by the SFC, and they are contractual rather than statutory. A Main Board applicant needs a trading record, management continuity and one of three alternative financial tests. Listing then brings continuing obligations, including a minimum public float.
Getting listed is the easy half to understand. Staying listed is where most of the rules live, and where most candidates stop reading.

- Main Board entry
- Trading record, management continuity, and one of three financial tests
- After listing
- Continuing obligations, including disclosure and a minimum public float
Who makes the Listing Rules?
The Exchange. A company applying to list contracts with SEHK to comply, and the Listing Committee decides applications and disciplinary matters. The SFC sits behind the process with statutory powers over the Exchange and over the offering of investments to the public, but it does not run the Listing Rules.
That division is examined directly. If a stem asks who enforces a breach of the Listing Rules, the answer is the Exchange.
What are the three Main Board financial tests?
An applicant must satisfy one of them, alongside the trading record and management continuity requirements. Learn what each test is measuring, because the thresholds move.
| Test | What it demands | Who it suits |
|---|---|---|
| Profit test | Profit attributable to shareholders across the trading record period, with a market capitalisation floor | A smaller company that is genuinely profitable |
| Market capitalisation and revenue test | A high market capitalisation at listing plus substantial revenue in the most recent audited year | A larger business with revenue but no profit yet |
| Market capitalisation, revenue and cash flow test | Market capitalisation, revenue, and positive aggregate operating cash flow over the trading record period | A business generating cash but not accounting profit |
We do not quote the figures. They are revised periodically, they are not in our verified fact base, and a stale threshold recited with confidence is a liability. Take them from the current Listing Rules shortly before you sit.
The reasoning behind the structure is worth holding, because it is more durable than any number. A company can be worth backing because it earns money, or because it is large and sells a great deal, or because it converts that selling into cash. The three tests are three ways of demonstrating substance.
What is the public float requirement?
A listed issuer must keep a minimum proportion of its shares in public hands, so that a genuine market exists in the stock rather than a nominal one. The Exchange may accept a lower percentage from issuers of substantial market capitalisation, on the reasoning that a smaller slice of a very large company is still a lot of tradeable stock. A minimum spread of shareholders is required too, so the float is genuinely distributed rather than parked with a handful of friendly holders.
The public float regime was revised with effect from 2026. Any percentage you have seen in an older textbook should be checked against the Rules in force on your examination date before you rely on it.
How does GEM differ from the Main Board?
| Main Board | GEM | |
|---|---|---|
| Profit requirement | One of three financial tests, one being a profit test | No profit requirement |
| Trading record | Longer | Shorter |
| Market capitalisation floor | Higher | Lower |
| Key financial condition | Varies with the test chosen | Positive aggregate operating cash flow over the trading record period |
| Transfer | n/a | No automatic promotion; must satisfy Main Board requirements |
The transfer point is the examinable one. GEM is a separate market with a lower entry standard, not a waiting room.
What are continuing obligations?
The duties that attach after listing, and the part of the rulebook a working intermediary actually encounters.
- Disclosure of inside information, which is a statutory duty under the Ordinance as well as a listing requirement, and sits alongside the market misconduct regime.
- Periodic financial reporting, on the timetable the Rules prescribe.
- Notifiable transactions, where deals above certain size ratios require announcement, and larger ones require shareholder approval.
- Connected transactions, where dealings with directors, substantial shareholders and their associates need disclosure and often independent shareholder approval.
- Maintaining the public float, with the Exchange able to suspend trading where it falls away.
- Corporate governance, including board composition, independent non-executive directors and audit committee requirements.
Connected transactions and notifiable transactions are the two that generate real work in practice. For Paper 1 you need to know they exist, what triggers them and roughly what they require.
A worked question
A listed issuer proposes to sell a subsidiary to a company controlled by its chairman. Which requirement is most directly engaged?
- SFC authorisation of the transaction under the product codes
- The connected transaction rules, requiring disclosure and generally independent shareholder approval
- The Takeovers Code mandatory general offer obligation
- No requirement, provided the price is determined by an independent valuer
How deep should you go?
Not deep. The Listing Rules run to hundreds of pages and Paper 1 samples them at the level of structure: who makes them, what an applicant must show, what an issuer must keep doing. Reading the actual chapters is a poor use of your time unless you work in listed company compliance.
My honest view is that this heading is over-taught relative to its weight. It has visible, memorisable numbers, so course providers love it, and candidates feel productive drilling thresholds. Meanwhile the numbers change and the marks sit elsewhere. Learn the three tests by shape, learn the continuing obligations by name, and move on to Topic 9.
Common questions
Who enforces the Hong Kong Listing Rules?
The Stock Exchange of Hong Kong, through its Listing Committee. The Rules are contractual rather than statutory: a company agrees to comply as a condition of listing. The SFC has statutory oversight of the Exchange but does not administer the Listing Rules itself.
What are the three Main Board financial tests?
A profit test, a market capitalisation and revenue test, and a market capitalisation, revenue and cash flow test. An applicant must satisfy one of the three, together with a trading record and management continuity. The specific thresholds are revised periodically and should be read from the current Rules.
Is GEM a stepping stone to the Main Board?
Not automatically. GEM is a separate market with a lower entry standard and no profit requirement. A GEM issuer that wants to transfer to the Main Board must satisfy Main Board requirements in the same way as any other applicant.
What is a connected transaction?
A transaction between a listed issuer and a connected person, such as a director, a substantial shareholder or their associates. The Listing Rules require disclosure and, above certain thresholds, approval by independent shareholders, because the interests on both sides may not be independent.
What is the public float requirement?
A listed issuer must keep a minimum proportion of its shares in public hands, with a minimum spread of holders, so a genuine market exists in the stock. The Exchange may accept a lower percentage from very large issuers, and the regime was revised with effect from 2026.
