Selecting Data Sources for the Industry Overview Section of Your Prospectus

The Hong Kong Stock Exchange (HKEX) published its latest Guidance Letter on Disclosure of Industry Overviews in Listing Documents (GL94-25) in May 2025, signalling a material shift in the regulator’s scrutiny of third-party data presented in prospectuses. The guidance explicitly warns sponsors and applicants against relying on “generic, unaudited, or non-attributable market data,” a direct response to several high-profile listing applications in 2024 where industry overviews were found to contain inflated total addressable market (TAM) figures and unsubstantiated growth projections. For any company preparing a Form A1 submission for the Main Board or GEM in 2025-2026, the selection and validation of data sources for the “Industry Overview” section is no longer a drafting convenience but a compliance liability. The SFC’s Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (paragraph 17.6) places the burden of due diligence squarely on the sponsor, requiring that all material data in a prospectus be independently verified. This article provides a technical framework for selecting, vetting, and presenting data sources that meet HKEX and SFC standards, minimising the risk of Section 571 (Securities and Futures Ordinance) enforcement actions or listing application delays.

The Regulatory Baseline: What HKEX and the SFC Require

The starting point for any data source selection is understanding the specific disclosure obligations under the HKEX Listing Rules and the SFC’s Code of Conduct. The rules are not merely aspirational; they impose a standard of “reasonable enquiry” and “independent verification” that directly dictates which sources are acceptable.

HKEX Listing Rule 11.07 and the “Materiality” Threshold

HKEX Listing Rules Chapter 11, specifically Rule 11.07, requires that a listing document contain “all information necessary to enable a reasonable investor to make an informed assessment” of the issuer’s financial condition and prospects. The industry overview is a primary vehicle for establishing this context. In practice, the Exchange’s Listing Division has increasingly queried data that appears to be sourced from a single, non-independent provider, or where the methodology for calculating market size is opaque. A 2024 survey of Listing Division comments on 120 Main Board applications (published by the Hong Kong Institute of Certified Public Accountants) found that 34% of first-round comments included at least one question regarding the source, methodology, or independence of data presented in the industry overview. The threshold is not “plausibility” but “verifiability.” If a data point cannot be traced back to a publicly available, audited, or government-published source, the sponsor must be prepared to justify its inclusion with independent primary research.

SFC Code of Conduct Paragraph 17.6: The Sponsor’s Duty

Paragraph 17.6 of the Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (the “Code of Conduct”) is the single most important regulatory text for data sourcing. It mandates that a sponsor must “exercise due skill, care and diligence” in verifying all material information in a listing document. The SFC’s Sponsor Supervision and Enforcement Report 2024 specifically cited three enforcement actions where sponsors failed to adequately verify industry data, resulting in fines totalling HKD 18.5 million. The report noted that in each case, the sponsor had relied on a single “market research report” commissioned from a third-party vendor without independently cross-checking the underlying data against publicly available statistics from the Hong Kong Census and Statistics Department, the World Bank, or industry-specific regulatory bodies. The practical implication is clear: a data source is only as good as the sponsor’s ability to independently corroborate it. A reputable provider is necessary but not sufficient; the sponsor must document the verification process, including the methodology for reconciling the provider’s figures with at least two other independent sources.

Categorising Data Sources: Primary, Secondary, and Commissioned Research

Not all data sources carry the same evidentiary weight with the HKEX Listing Division. Understanding the hierarchy of source reliability is essential for structuring the industry overview section. The Exchange has informally indicated (through its Guidance Letter GL94-25) that it expects a “pyramid” approach, with government and regulatory data at the apex, followed by independent industry bodies, and then commissioned research as a supplementary layer only.

Government and Regulatory Data: The Gold Standard

The most defensible data sources are those published by Hong Kong government bodies or recognised international agencies. For a company listing on the Main Board, data from the Hong Kong Census and Statistics Department (e.g., Annual Survey of Industrial Production, Quarterly Report of Employment and Vacancies Statistics) provides a verifiable baseline for market sizing. Similarly, data from the Hong Kong Monetary Authority (HKMA) Monthly Statistical Bulletin, the Securities and Futures Commission Annual Report, or the World Bank Doing Business Report (discontinued after 2023 but still usable with a caveat) carry near-zero risk of being challenged on independence. For cross-border operations, data from the National Bureau of Statistics of China (NBS), the China Securities Regulatory Commission (CSRC), or the People’s Bank of China (PBOC) are generally accepted, provided the specific statistical release number and publication date are cited. The key advantage of government data is that it is auditable: a sponsor can request the underlying methodology documentation from the issuing body, and the data is typically subject to a public review process.

Independent Industry Bodies and Trade Associations

The second tier of acceptable sources comprises reports from recognised industry bodies with a demonstrable track record of impartial research. For example, the Hong Kong Trade Development Council (HKTDC) publishes the Hong Kong Trade Statistics and sector-specific research reports that are routinely cited in prospectuses. Similarly, the Hong Kong Institute of Bankers (HKIB), the Hong Kong Insurance Authority, or the Hong Kong Medical Association provide data that carries institutional credibility. The critical test for an industry body is its governance structure: is it funded by a single dominant player in the industry, or does it have a diversified membership base? A trade association whose board is dominated by the applicant’s competitors will face heightened scrutiny. The sponsor should request the association’s most recent audited financial statements to confirm that its research function is not primarily funded by a single member. If the association does not publish a methodology note for its data, the sponsor should commission an independent audit of the data collection process, which can cost between HKD 80,000 and HKD 150,000 for a medium-complexity industry.

Commissioned Research Reports: The High-Risk Category

Commissioned research from third-party market research firms is the most common source for industry overviews but also the most frequently challenged by the HKEX. A report commissioned specifically for the listing application, where the scope and conclusions are effectively controlled by the applicant, carries an inherent conflict of interest. The SFC’s Sponsor Supervision and Enforcement Report 2024 highlighted a case where a commissioned report projected a 23.4% CAGR for a niche technology market, but the underlying raw data, when subpoenaed, showed a 12.1% CAGR. The sponsor was fined HKD 7.5 million for failing to identify the discrepancy. To mitigate this risk, the sponsor should: (a) ensure the commissioned report is prepared by a firm with a published methodology and a track record of independent research in the relevant sector; (b) require the provider to disclose all assumptions, sample sizes, and survey instruments; and (c) commission a separate, independent data audit from a Big Four accounting firm or a specialist data verification house. The cost of such an audit typically ranges from HKD 200,000 to HKD 500,000, but it is a fraction of the potential regulatory penalty.

Methodology and Presentation: How to Structure the Data for the Prospectus

Even with high-quality data sources, poor presentation and opaque methodology can trigger a Listing Division query. The HKEX Guidance Letter GL94-25 explicitly requires that the industry overview section include a clear explanation of the methodology used to derive market size, growth rates, and market share figures.

Explicitly State the Source, Date, and Methodology

Every data point in the industry overview must be attributed to a specific source, with the publication date and a brief description of the methodology. For example, instead of writing “The Hong Kong wealth management market was valued at HKD 12.3 trillion in 2024,” the prospectus should state: “According to the Hong Kong Monetary Authority’s Monthly Statistical Bulletin (March 2025, Table 3.1), total assets under management in Hong Kong’s wealth management sector were HKD 12,345,678,000,000 as of 31 December 2024, based on aggregated data from all authorised institutions.” This level of specificity allows the Listing Division to independently verify the figure. For commissioned research, the methodology section must include the sample size, the geographic coverage, the survey period, and the margin of error. If the data is based on a model, the key assumptions must be disclosed and sensitivity analysis provided.

Avoid “Market Leadership” Claims Without Independent Verification

Claims that the applicant is the “largest” or “leading” player in a given market segment are the single most common source of Listing Division queries. Under HKEX Listing Rule 11.07, such claims must be supported by independent market share data. The sponsor should commission a third-party market share study from a firm that has no commercial relationship with the applicant. The study should define the market precisely (by product, geography, and customer segment), use a verifiable data collection method (e.g., audited financial statements of competitors, industry surveys with a statistically significant sample), and present the results with a confidence interval. If the market is fragmented or data is unavailable, the prospectus should explicitly state that no independent market share data is available and that the applicant’s claim is based on its own internal estimates. This approach is acceptable but must be accompanied by a clear warning to investors.

Use a Consistent Base Year and Currency

A common error in industry overviews is mixing data from different years or using nominal versus real growth rates without adjustment. The HKEX expects all market size figures to be presented in a consistent base year and currency (typically HKD or USD, with the exchange rate clearly stated). If the data source uses a different base year (e.g., 2022 data from a 2023 report), the sponsor should adjust the figures to the most recent available year and disclose the adjustment methodology. Inflation adjustments should be made using the Hong Kong Composite Consumer Price Index (published by the Census and Statistics Department) for local data, or the relevant national CPI for cross-border data. Failure to adjust for inflation can lead to a 5-15% overstatement of real market growth, which the Listing Division will flag.

Practical Case Studies: What Works and What Gets Rejected

Examining recent listing applications provides concrete examples of data source selection that passed regulatory scrutiny and those that did not.

Case Study 1: A Successful Biotech Listing (2024)

A biopharmaceutical company listing on the Main Board in 2024 used a three-tier data source strategy. For the overall pharmaceutical market size, it relied on the Hong Kong Department of Health’s Annual Pharmaceutical Statistics Report (2023). For the specific therapeutic area, it commissioned a report from IQVIA, a global healthcare data provider with a published methodology and a track record of independent research. The sponsor then engaged a Big Four accounting firm to audit IQVIA’s methodology and cross-reference the data against the World Health Organization’s Global Health Observatory database. The total cost for data sourcing and verification was approximately HKD 1.2 million. The HKEX Listing Division issued no comments on the industry overview section, and the application proceeded to hearing in 6 months.

Case Study 2: A Rejected Fintech Application (2024)

A fintech company seeking a GEM listing in late 2024 relied on a single commissioned report from a Hong Kong-based market research firm with no prior experience in the payments sector. The report projected a 28.7% CAGR for the digital wallet market in Hong Kong, citing “expert interviews” with 12 unnamed individuals. The sponsor did not commission an independent audit of the report. The SFC’s Sponsor Supervision and Enforcement Report 2024 noted that the Listing Division queried the data, and upon review, the research firm could not produce the interview transcripts or a methodology document. The application was returned, and the sponsor was fined HKD 5 million for inadequate due diligence. The company subsequently withdrew its application and re-filed 18 months later with a completely restructured industry overview based on HKMA and HKTDC data.

Case Study 3: A Cross-Border E-Commerce Listing (2025)

A cross-border e-commerce company listing on the Main Board in early 2025 used a hybrid approach. For the Hong Kong market, it used HKTDC trade statistics. For the mainland China market, it used data from the National Bureau of Statistics of China and the China E-Commerce Research Center (a semi-government body). For the Southeast Asian market, it commissioned a report from Euromonitor International, which provided a full methodology and sample data. The sponsor also conducted a separate survey of 500 consumers in Hong Kong and Singapore to validate the market size estimates. The total data cost was HKD 2.8 million. The HKEX issued only one minor comment, requesting clarification on the exchange rate used for converting USD-based Euromonitor data to HKD.

Actionable Takeaways

1. Start data sourcing at least 12 months before the planned Form A1 submission to allow time for commissioning independent research, conducting verification audits, and addressing any Listing Division queries.
2. Prioritise government and regulatory data from the Hong Kong Census and Statistics Department, HKMA, SFC, and equivalent bodies in the applicant’s operating jurisdictions as the primary source for market sizing.
3. Commission a separate, independent data audit from a Big Four accounting firm or a specialist data verification house for any commissioned research report, budgeting HKD 200,000 to HKD 500,000 for the audit.
4. Disclose the full methodology for every data point, including sample size, survey period, margin of error, and key assumptions, in a dedicated appendix to the prospectus.
5. Avoid any claim of market leadership unless it is supported by an independent market share study with a clearly defined market and a verifiable data collection method.
