What this guide covers
- Under HKEX Main Board Listing Rule 8.04, both the issuer and its business must be suitable for listing in the Exchange's opinion, a discretionary suitability test that sits on top of the numeric profit and market capitalisation tests.
- HKEX's own guidance for listing applicants flags business sustainability as a distinct area of scrutiny, including heavy indebtedness with minimal cash, long or deteriorating receivable turnover days, loss of major customers, and reliance on discretionary government subsidies to meet debt payments.
- Global IPO investors in 2025 were applying increased scrutiny to fundamentals, profitability pathways and governance, and were seeking resilient business models that can withstand market fluctuations and deliver sustainable growth.
- Hong Kong's active IPO application pipeline as of December 2025 was concentrated in three sectors: technology, media and telecom at 39 percent, healthcare and life sciences at 21 percent, and industrials at 18 percent, showing where investor and applicant demand currently sits.
The Main Board's financial tests decide whether a company may apply. They do not decide whether it will be admitted, or whether investors will buy. Both questions turn on a judgement about the business itself: whether it will still be earning in three years, who controls its cash, and why it wants public money now. The Exchange has written down how it reaches that judgement, and in 2025 investors were asking much the same questions. This guide sets out the list so a board can test its own company against it first.
Suitability sits above the numbers
Rule 8.04 states that both the issuer and its business must, in the opinion of the Exchange, be suitable for listing1. The numeric tests in Rule 8.05 (profit, or market capitalisation with revenue and cash flow, or market capitalisation with revenue) come after it1. Suitability is a discretionary judgement, and the Exchange's guidance says there is no prescribed bright-line test for it2. A company that clears every figure can still be asked to explain why its business will last.
What the Exchange reads as a sustainability concern
The Guide for New Listing Applicants opens its chapter on business sustainability with a warning: an applicant that meets the Rule 8.05 requirements at the time of filing may still raise concerns if it recorded deteriorating revenue and profit, or material losses, during or after the track record period2.
The Exchange then weighs three things2. The first is how susceptible financial performance is to changes beyond the company's control, with the example of a slight rise in raw material costs that cannot be passed on to customers and tips the company into a net loss2. The second is whether the cause of a decline is expected to continue, as with a change in consumer preference or a product replaced by alternative technology, or is the ordinary cycle of the industry2. The third is whether the applicant has shown it can mitigate the exposure or turn the business around, by diversifying revenue sources, expanding the customer base, or cutting costs2.
A board that can answer those three questions on one page, with numbers, has done most of the vetting in advance.
The balance sheet and the receivables ledger
The Guide's list of features that raise concern starts with the balance sheet. Heavy indebtedness with minimal cash at bank and unutilised banking facilities, net current liabilities, and sole reliance on bank facilities to maintain a positive cash balance all appear on it2. So does doubt about whether the company could raise independent financing once facilities guaranteed by its controlling shareholders are used up2.
Significant trade receivables, long and deteriorating receivable turnover days that raise a recoverability question, inadequate credit risk controls over the creditworthiness of customers, and the loss of major customers are each listed2. Reliance on discretionary government subsidies to meet debt payments closes the list2.
We would expect a finance team to know its receivable turnover days for each year of the track record, and the direction of travel, before a sponsor asks.
Business model, concentration and unusual arrangements
A second group of concerns sits in the business model: a loss-making history likely to continue in the foreseeable future, made worse by uncertainty over expansion plans; an applicant that is primarily a price taker with little bargaining power over customers or suppliers; and a cash flow mismatch between the settlement of expenses and a long billing cycle with major customers2.
A third group covers factors outside the applicant's control: high customer concentration that raises doubts about bargaining power, projects with very long break-even or payback periods, unusual business arrangements without solid evidence that they follow an industry norm, and infrequent, unpredictable, non-recurring sales with no analysis of the company's ability to sustain them2.
Mid-market companies in North America and Australia often grew up around a few anchor customers. That history is not disqualifying, but it will be examined.
The reason for listing, in writing
In assessing suitability the Exchange may consider whether the listing is consistent with the applicant's business strategies, including the proposed use of proceeds, and whether the applicant has genuine funding needs2. An applicant that cannot demonstrate the commercial rationale for listing may be found not suitable2.
The Exchange expects a detailed analysis of the use of proceeds, at a level of specificity commensurate with the applicant's past and future business strategies and observed industry trends, and of future objectives and strategies, demonstrating a detailed strategic plan for operations and growth2. A use of proceeds section that reads as a placeholder invites a query on the whole application.
What investors were asking in 2025
Global IPO investors in 2025 were applying increased scrutiny to fundamentals, profitability pathways and governance, and were seeking resilient business models that can withstand market fluctuations and deliver sustainable growth3. Read against the Guide, that is the same enquiry from the buy side: is the profit real, will it survive a change in conditions, and can the board be trusted with the answer. The work that satisfies the Exchange on sustainability is the work that satisfies the fund manager.
Where the pipeline sits
As at 7 December 2025, active IPO applications in Hong Kong were distributed 39 percent technology, media and telecom, 21 percent healthcare and life sciences, and 18 percent industrials4. The pipeline as a whole held more than 300 applications4, and the commentary behind it describes a steady influx of tech and biotech firms choosing Hong Kong, with rising participation from foreign investors4.
For a company in one of those three sectors, that means comparables, specialist coverage and investors who already hold the peer group. For a company outside them, the sector case has to be made from first principles.
The questions we would put to a board
- Has revenue or profit fallen in any track record year, and is the cause cyclical or structural2?
- What are cash and unutilised facilities against debt, and does any facility rest on a shareholder guarantee2?
- What are receivable turnover days for each of the three years, and which way are they moving2?
- What share of revenue comes from the largest customers, and has a major customer been lost2?
- Does any subsidy income go toward debt service2?
- Is the company in technology, media and telecom, healthcare and life sciences, or industrials, and if not, what is the sector argument4?
The next step
Ask the chief financial officer for a sustainability schedule covering the last three audited years: cash and unutilised facilities against debt due, receivable turnover days by year, revenue by largest customers, and any subsidy income set against debt service2. Alongside it, draft the use of proceeds section to the standard in the Guide, tied to a written strategic plan2. Put both in front of a Hong Kong sponsor and ask one question: on these numbers, would the Exchange raise a business sustainability query. The answer decides whether the application goes in now or after another year of trading.
