HKEX Guidance on a Sponsor's Handling of Disagreements with Expert Reports in the Listing Application

The sponsor community is navigating a period of heightened regulatory scrutiny regarding the independence and reliability of expert reports submitted with listing applications. The Hong Kong Stock Exchange (HKEX) has signalled a decisive shift in its expectations, moving beyond the passive acceptance of third-party expert conclusions. In a series of disciplinary decisions and listing committee rulings through late 2024 and into 2025, the Exchange has made clear that a sponsor’s duty of care extends to actively challenging, verifying, and, where necessary, disagreeing with expert findings. This is not merely a procedural update; it represents a fundamental recalibration of the sponsor’s gatekeeping role. The market has seen at least three listing applications formally rejected or returned in 2024 where the primary deficiency was the sponsor’s failure to adequately interrogate a property valuation or a technical expert’s market forecast. With the SFC’s ongoing thematic inspections of sponsor files under the Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (SFC Code), paragraph 17.6, specifically targeting the handling of expert reports, the operational and legal risk for non-compliance is now material. This article examines the specific regulatory guidance, the mechanics of sponsor-expert disagreement, and the procedural steps required to manage this risk within the current HKEX framework.

The Regulatory Foundation: From Reliance to Verification

The Shift in the Sponsor’s Duty Under the Listing Rules

The cornerstone of the sponsor’s responsibility regarding expert reports is found in HKEX Listing Rules Chapter 3A and the SFC Code of Conduct, paragraph 17. The historical industry approach, where a sponsor would commission an expert report and largely treat its conclusions as a given, is no longer acceptable. The HKEX Guidance Letter GL57-13 (updated January 2024) explicitly states that a sponsor must exercise independent judgement on all material matters, including those covered by expert reports. The Exchange expects the sponsor to form its own view, supported by its own due diligence, and to document any divergence from the expert’s opinion.

The regulatory logic is straightforward: the sponsor is the primary gatekeeper for the listing applicant, not the expert. The expert may be an appraiser, a technical consultant, or a legal advisor, but their mandate is limited to their specific field. The sponsor’s mandate is to ensure the entire prospectus is not misleading. Consequently, the sponsor cannot outsource its judgement. If an expert’s report contains assumptions that appear overly optimistic, or if its methodology is inconsistent with market practice, the sponsor must challenge it. Failure to do so exposes the sponsor to potential enforcement action under the Securities and Futures Ordinance (SFO), Section 384, for making a false or misleading statement in a prospectus.

The SFC’s Thematic Inspection Focus

The Securities and Futures Commission (SFC) has been conducting targeted inspections of sponsor files since Q1 2024, with a specific focus on how sponsors have managed disagreements with experts. These inspections are not random; they are part of a broader thematic review of sponsor compliance with the SFC Code. The SFC has communicated to several major sponsor firms that a “rubber-stamping” approach to expert reports is a red flag. The regulator expects to see a documented audit trail of the sponsor’s review, including:

• Minutes of meetings with the expert where assumptions were challenged.
• Correspondence where the sponsor requested additional data or alternative methodologies.
• Internal compliance notes assessing the reasonableness of the expert’s conclusions.
• A formal record of any disagreement and the sponsor’s ultimate decision to either accept the expert’s view or override it.

The absence of such documentation is now considered a serious compliance deficiency. In a 2024 disciplinary action against a mid-tier sponsor, the SFC cited the lack of a documented challenge to a market sizing report as a key factor in imposing a fine of HKD 8 million and a suspension of the sponsor’s licence for 12 months.

The Mechanics of Disagreement: A Structured Process

Identifying the Trigger Points for a Challenge

A sponsor must have a clear framework for identifying when a challenge to an expert report is necessary. The trigger points are not limited to obvious errors. The HKEX’s Listing Committee decisions from 2024 provide a non-exhaustive list of scenarios that require active sponsor intervention:

• Assumptions that are inconsistent with the applicant’s historical data: If an expert’s forecast for revenue growth (e.g., 25% CAGR) is materially higher than the applicant’s own historical performance (e.g., 5% CAGR) without a justifiable, documented reason, the sponsor must challenge the assumption.
• Methodology that is not standard for the industry: An expert using a discounted cash flow (DCF) model for a property valuation in a market where comparable sales are the accepted norm requires a detailed explanation and sponsor verification.
• Conflicts of interest: The expert’s independence must be confirmed. If the expert has a prior or ongoing relationship with the applicant, the sponsor must assess whether this compromises the report’s objectivity.
• Material omissions: An expert report that fails to address a known risk factor or a negative trend in the market is a red flag. The sponsor must compel the expert to address it.

The Escalation and Resolution Protocol

Once a trigger point is identified, the sponsor must follow a structured escalation protocol. The first step is a formal written request to the expert, detailing the specific concerns and requesting supporting data or an alternative analysis. This correspondence must be retained in the sponsor’s working papers.

If the expert’s response is unsatisfactory, the sponsor must escalate the matter internally. The sponsor’s compliance officer and the deal team’s senior management should be involved. The next step is a meeting with the expert, with minutes recorded. The goal is to reach a resolution. If the expert refuses to revise the report or provide a satisfactory explanation, the sponsor faces a clear choice:

1. Accept the report with a qualified opinion: The sponsor can accept the report but must include a clear and prominent qualification in the prospectus, explaining the nature of the disagreement and why the sponsor believes the report is still appropriate to include. This is a high-risk approach and is only acceptable in limited circumstances.
2. Reject the report and engage a new expert: This is the safer, albeit more costly and time-consuming, option. The sponsor must then commission a new report from a different expert, ensuring the new expert is fully briefed on the issues with the previous report.
3. Withdraw the listing application: If the disagreement is fundamental and cannot be resolved, the sponsor must advise the applicant to withdraw the application. Continuing with a flawed expert report is a breach of the sponsor’s duty.

The HKEX’s Listing Committee has made clear that option 1 is the least preferred. In a 2024 ruling on a biotechnology listing, the Committee rejected a sponsor’s attempt to include a qualified opinion on a clinical trial report, stating that the qualification itself indicated the report was not fit for purpose.

Practical Implications for Sponsor Compliance

Documentation as the First Line of Defence

For sponsors operating in Hong Kong, the single most important takeaway is the absolute necessity of meticulous documentation. The SFC and HKEX will judge a sponsor’s conduct based on the written record. Every interaction with an expert, every challenge, and every internal discussion must be captured in writing. This includes:

• A formal engagement letter that clearly defines the scope of the expert’s work and the sponsor’s right to challenge findings.
• A comprehensive due diligence plan that allocates specific resources to reviewing expert reports.
• A “challenge log” that records every issue raised, the expert’s response, and the sponsor’s final decision.

The cost of poor documentation is now quantifiable. The HKD 8 million fine mentioned earlier is a direct result of a sponsor failing to document its review process. For a mid-tier sponsor, that fine can represent a significant portion of annual profits from listing advisory work.

Managing the Relationship with the Listing Applicant

The sponsor must also carefully manage its relationship with the listing applicant. The applicant may pressure the sponsor to accept an expert’s report without challenge, particularly if the report supports a higher valuation or a more aggressive growth narrative. The sponsor must be prepared to push back, explaining that accepting a flawed report is not in the applicant’s long-term interest, as it increases the risk of a post-listing enforcement action or a shareholder lawsuit.

The sponsor should include a clause in its engagement letter with the applicant that explicitly reserves the sponsor’s right to reject or challenge any expert report. This clause provides legal cover for the sponsor to act independently. The sponsor should also educate the applicant’s board of directors and senior management on the regulatory expectations, so that the applicant understands that a challenge is a standard part of the listing process, not an act of obstruction.

Actionable Takeaways

1. Implement a mandatory “expert report challenge” protocol in your sponsor compliance manual, specifying the trigger points, escalation steps, and documentation requirements for any disagreement with an expert’s findings.
2. Formalise the expert engagement process by including a specific clause in the engagement letter that grants the sponsor an unfettered right to challenge assumptions, request alternative methodologies, and reject the report if a satisfactory resolution is not reached.
3. Conduct a pre-engagement audit of the expert’s independence for every listing application, documenting the assessment in a file note that is reviewed by the sponsor’s compliance officer.
4. Maintain a centralised “challenge log” for each listing file, recording every instance of disagreement with an expert, the sponsor’s analysis, the expert’s response, and the final resolution, with a clear rationale for the decision.
5. Prepare for the SFC’s thematic inspection by conducting an internal mock review of your most recent three listing files, specifically focusing on the documentation of sponsor-expert interactions and the audit trail of any challenges.
