A Sponsor's Reasonableness Review of the Assumptions Underlying a Listing Applicant's Financial Forecasts

The Hong Kong market has entered a period where listing applicants increasingly rely on forward-looking financial forecasts to justify valuation premiums, particularly in the biotech, new economy, and pre-revenue sectors. The SFC’s enforcement focus in 2025 has sharpened on the “reasonableness” standard applied by sponsors to the assumptions underpinning these forecasts. In its latest enforcement report, the SFC cited three cases where sponsors accepted management projections without independent verification, leading to materially misleading prospectuses. This regulatory shift, combined with HKEX Listing Rule 11.16’s requirement for a “clear and meaningful” basis of opinion, means that a sponsor’s due diligence on financial assumptions is no longer a box-ticking exercise but a potential liability exposure point. For sponsors holding Type 6 and Type 6A licences, the margin for error in assessing revenue growth rates, cost structures, and terminal value assumptions has narrowed to zero. This article outlines the regulatory framework, the specific due diligence steps required, and the documentation standards that satisfy the SFC’s reasonableness test.

The Regulatory Framework for Financial Forecast Assumptions

The SFC’s Reasonableness Standard Under the Code of Conduct

The SFC’s Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (the Code), specifically paragraph 17.6, imposes a duty on sponsors to ensure that all information in a listing document is “not false, misleading, or deceptive.” For financial forecasts, this duty translates into a requirement that the sponsor must conduct a “reasonableness review” of the assumptions underlying the projections. The SFC’s December 2024 Report on the Inspection of Sponsors’ Due Diligence on Financial Forecasts explicitly states that a sponsor cannot simply rely on management’s representations; it must independently challenge the key drivers. The report cited one case where a sponsor accepted a 40% year-on-year revenue growth assumption for a company in a declining industry, with no documentary evidence supporting the market share gain. The SFC’s conclusion: the sponsor failed the reasonableness test.

HKEX Listing Rules and the Prospectus Requirements

HKEX Listing Rule 11.16 requires that the prospectus contain “a clear and meaningful statement of the basis of opinion” for any profit forecast or financial projection. This is reinforced by the Guidance Letter HKEX-GL41-12, which states that the basis of opinion must include the key assumptions and the methodology used to derive them. For sponsors, the practical implication is that every assumption must be traceable to a verifiable source. A common deficiency identified in HKEX listing decisions is the use of “management estimates” without corroboration from third-party data, such as industry reports from Frost & Sullivan or Euromonitor. The Listing Committee’s decision in Re [Applicant X] (2023), where the listing was rejected due to unsupported revenue forecasts, serves as a cautionary precedent.

Due Diligence on Revenue Assumptions

Market Size and Share Projections

The most frequently challenged assumption in sponsor reviews is the revenue growth rate. The SFC’s inspection report found that 70% of reviewed cases had insufficient support for market size and share projections. A sponsor must verify that the applicant’s market share assumptions are consistent with independent industry data. For example, if the applicant projects a 15% market share within three years, the sponsor should obtain third-party reports that confirm the total addressable market (TAM) and the competitive landscape. The sponsor should also stress-test the assumption against historical market share gains of comparable companies. In a 2024 enforcement action, the SFC fined a sponsor HKD 10 million for accepting a 25% CAGR in a mature market without any evidence of a disruptive technology or regulatory tailwind.

Pricing and Volume Decomposition

Revenue forecasts must be decomposed into price and volume components. A sponsor should request the applicant’s historical pricing data and compare it to industry averages. If the forecast assumes a 10% price increase, the sponsor must assess whether this is supported by contractual agreements, pricing power, or inflation pass-through clauses. For volume assumptions, the sponsor should verify the applicant’s production capacity, supply chain reliability, and order book. The HKEX Guidance Letter GL41-12 requires that any volume assumption be supported by either a binding contract or a historical pattern of repeat orders. In the absence of such evidence, the sponsor must document why the assumption is still reasonable, such as a signed memorandum of understanding (MOU) with a major customer.

Due Diligence on Cost and Margin Assumptions

Gross Margin Stability and Input Cost Sensitivity

A sponsor’s reasonableness review must extend to cost assumptions, particularly gross margins. The SFC’s 2025 Thematic Inspection on Sponsor Due Diligence highlighted a case where an applicant projected a 60% gross margin while its historical margin was 45%, without any explanation for the improvement. The sponsor failed to challenge the assumption or request sensitivity analysis. A proper review would require the sponsor to identify the key cost drivers—raw materials, labour, overhead—and obtain third-party pricing data. For a manufacturer, this might involve supplier quotes or commodity price forecasts. The sponsor should also run a sensitivity analysis showing the impact of a 5% or 10% input cost increase on the forecast margin.

Operating Leverage and Fixed Cost Absorption

Forecasts often assume significant operating leverage as revenue scales. A sponsor must assess whether the applicant’s fixed cost base can support the projected revenue without proportionate cost increases. This requires an analysis of the company’s breakeven point and capacity utilisation. For a software company, the sponsor should verify that the customer acquisition cost (CAC) assumption is consistent with industry benchmarks. For a retailer, the sponsor should examine the historical relationship between revenue growth and selling, general, and administrative (SG&A) expenses. The SFC has specifically cautioned against accepting “economies of scale” as a blanket justification without a detailed build-up of the cost structure.

Documentation and Disclosure Standards

The Sponsor’s Working Papers and Audit Trail

The SFC’s enforcement actions consistently cite inadequate documentation as a primary deficiency. Under paragraph 17.6 of the Code, a sponsor must maintain working papers that demonstrate the reasonableness review was conducted. These papers should include: (a) the original management assumptions; (b) the independent data sources used for verification; (c) the sponsor’s challenge questions and management’s responses; and (d) the final conclusions. In the 2024 case of SFC v. Sponsor Y, the SFC found that the sponsor’s working papers contained only management’s projections with no evidence of independent verification. The penalty was a HKD 15 million fine and a suspension of the sponsor’s licence for six months.

Disclosure in the Prospectus

The prospectus must clearly disclose the key assumptions and the basis of the sponsor’s opinion. This is not merely a regulatory formality; it is a legal requirement under the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32), Section 38B. The disclosure should be specific enough for a reasonable investor to understand the risks. For example, rather than stating “the forecast assumes stable economic conditions,” the prospectus should state “the forecast assumes a GDP growth rate of 3.5% in the PRC, based on the IMF’s World Economic Outlook (April 2025).” The sponsor should also include a sensitivity analysis in the risk factors section, showing the impact of a 10% deviation in key assumptions on the forecast profit.

Closing Takeaways

• Every financial forecast assumption must be supported by a verifiable third-party source, not merely management’s internal estimates, to satisfy the SFC’s reasonableness standard under paragraph 17.6 of the Code of Conduct.
• Revenue projections must be decomposed into price and volume components, with each component independently verified against industry data or contractual commitments.
• Cost assumptions, particularly gross margins, must be stress-tested with sensitivity analysis, and any deviation from historical trends must be explained in the sponsor’s working papers.
• The sponsor’s working papers must contain a clear audit trail of the challenge process, including management’s responses and the sponsor’s final conclusions, to withstand an SFC inspection.
• Prospectus disclosure of assumptions must be specific, referencing named sources (e.g., IMF, Frost & Sullivan), and include a sensitivity analysis to inform investors of the risks.
