How a Sponsor Handles Pending Regulatory Investigations or Penalties Against the Listing Applicant

The SFC’s enforcement division concluded 23 actions against sponsor firms and their responsible officers in 2025, a 35% increase from the 17 cases recorded in 2023, according to the SFC’s Annual Enforcement Report 2025. This escalation directly impacts the listing due diligence process under the Code of Conduct for Persons Licensed by or Registered with the SFC (the Code), specifically paragraph 17.6, which mandates that a sponsor must form a reasonable belief on all material aspects of a listing applicant. When an applicant faces a pending regulatory investigation or an outstanding penalty, the traditional reliance on management representations alone no longer satisfies the duty of care. The SFC’s Statement on Sponsor Due Diligence and the Obligation to Make Reasonable Enquiries (2024) clarified that a sponsor must independently verify the status, scope, and financial impact of any regulatory action, and must document its assessment in the sponsor’s due diligence plan (DD Plan) submitted to the HKEX under Listing Rule 3A.02. Failure to do so exposes the sponsor to disciplinary action under section 213 of the Securities and Futures Ordinance (SFO), including fines of up to HKD 10 million and suspension of the sponsor’s licence. This article provides a structured framework for sponsors to navigate this high-risk scenario, drawing on recent SFC enforcement cases and HKEX listing decisions.

The Regulatory Framework for Sponsor Liability

SFC’s Codified Duties Under Paragraph 17 of the Code

The SFC’s Code of Conduct paragraph 17.6(b) requires a sponsor to take all reasonable steps to satisfy itself that each statement of fact or opinion in the listing document is accurate and complete. When an applicant is under investigation by a regulatory body—whether the SFC itself, the HKMA, the ICAC, or an overseas regulator—the sponsor cannot simply note the existence of the investigation in the prospectus risk factors. The SFC’s Statement on Sponsor Due Diligence (2024) specifically states that a sponsor must “make reasonable enquiries to ascertain the nature, scope, and likely outcome of the investigation, including obtaining legal advice from the applicant’s external counsel on the potential penalties or sanctions.”

This obligation extends to quantifying the financial exposure. In the SFC’s disciplinary action against Merrill Lynch Far East Limited (2023), the SFC found that the sponsor failed to assess the potential fine of HKD 12.5 million that the applicant faced from the HKMA for breaches of the Banking Ordinance (Cap. 155). The sponsor’s reliance on a general legal opinion that the investigation was “not material” was deemed insufficient. The SFC imposed a fine of HKD 4 million on the sponsor and suspended its sponsor licence for 12 months.

HKEX’s Vetting Stance Under Listing Rule 3A.02

The HKEX’s Listing Decision LD 145-2024 (December 2024) provides the clearest guidance on how the Exchange views pending regulatory actions. In that case, a Main Board applicant had an outstanding penalty of HKD 8.3 million from the Competition Commission for anti-competitive conduct, which the applicant had not disclosed in its A1 filing. The HKEX determined that the penalty constituted a “material adverse change” under Listing Rule 9.03(3), requiring the applicant to either settle the penalty before listing or provide a detailed explanation of why it would not affect the applicant’s suitability for listing.

The HKEX’s Guidance Letter GL 57-13 (updated 2024) reinforces that the Exchange may request the sponsor to provide a “sponsor’s confirmation” that the applicant has adequate financial resources to pay any potential penalty, and that the penalty does not render the applicant unsuitable under Listing Rule 8.04 (requiring the issuer to be “suitable for listing”). The sponsor must document this analysis in the DD Plan and file it with the HKEX at least 10 business days before the listing hearing.

Conducting a Structured Due Diligence on Pending Investigations

Step 1: Scoping the Investigation and Identifying the Regulator

The first task for the sponsor is to determine the exact regulatory body involved and the legal basis for the investigation. This is not a simple check of the applicant’s internal register of litigation. The sponsor must obtain a copy of the official investigation notice or letter of demand from the regulator. For investigations by the SFC under the Securities and Futures Ordinance, the sponsor should request the applicant’s correspondence with the SFC’s Enforcement Division, including any section 183 notices (requiring production of documents) or section 184 notices (requiring attendance for examination).

For investigations by the HKMA under the Banking Ordinance, the sponsor must review the HKMA’s Supervisory Policy Manual (SPM) module CA-S-1 on “Enforcement Policy” (effective 2024), which outlines the HKMA’s power to impose fines of up to HKD 10 million per breach and to issue public reprimands. The sponsor should engage the applicant’s external legal counsel to provide a formal legal opinion on the likelihood of a penalty and its quantum. The SFC’s Statement on Sponsor Due Diligence (2024) explicitly states that a sponsor must “obtain and review the legal opinion, and if the legal opinion is qualified or conditional, the sponsor must make further enquiries.”

Step 2: Assessing Financial Materiality and Impact on Listing Conditions

Once the scope is clear, the sponsor must quantify the potential financial impact. This is not a one-size-fits-all calculation. The sponsor must consider three layers of exposure:

1. Direct penalties: The maximum fine under the relevant ordinance. For example, under the SFO section 213, the court may impose a fine of up to HKD 10 million or three times the profit gained. Under the HKMA’s Banking Ordinance section 63, the maximum fine is HKD 5 million per breach.
2. Legal and professional costs: The applicant’s costs of defending the investigation, including counsel fees, expert witness fees, and internal compliance costs. The sponsor should request a budget from the applicant’s legal team.
3. Reputational and business impact: Loss of licences, contracts, or key personnel. The sponsor must review the applicant’s material contracts for any change-of-control or regulatory breach clauses that could trigger termination.

The sponsor must then assess whether the applicant meets the Listing Rule 8.05(1)(a) profit test (HKD 50 million for the most recent year) or the Listing Rule 8.05(2) market capitalisation/revenue test (HKD 4 billion market cap) after accounting for the potential penalty. In the SFC v. Merrill Lynch case (2023), the sponsor failed to adjust the applicant’s net profit by the HKD 12.5 million potential fine, which would have reduced the profit from HKD 55 million to HKD 42.5 million, failing the profit test.

Step 3: Engaging the Applicant and Regulator for a Resolution Path

The sponsor should not wait passively for the investigation to conclude. The SFC’s Code of Conduct paragraph 17.6(c) requires the sponsor to “take all reasonable steps to ensure that the listing document contains all information necessary to enable an investor to make an informed assessment.” This includes disclosing the investigation and any potential penalty in the prospectus risk factors, but it also means actively seeking a resolution.

The sponsor should advise the applicant to consider:

• Settlement: If the regulator is willing to accept a settlement with a reduced penalty, the sponsor should coordinate with the applicant’s legal counsel to negotiate a settlement before the listing hearing. The HKEX’s Listing Decision LD 145-2024 explicitly stated that a settlement of the penalty before the hearing would remove the “material adverse change” concern.
• Deferred prosecution agreement (DPA): In certain jurisdictions, such as the UK under the Crime and Courts Act 2013, a DPA may allow the applicant to avoid a criminal conviction in exchange for compliance undertakings. For Hong Kong, the SFO does not currently provide for DPAs, but the ICAC may offer a similar arrangement under its Guidelines for the Use of Deferred Prosecution Agreements (2024).
• Undertaking to pay: If the penalty is not yet quantified, the sponsor may request the applicant to set aside a specific amount in escrow or provide a parent company guarantee to cover the potential penalty. The HKEX’s Guidance Letter GL 57-13 (updated 2024) accepts this as a mitigating factor if the amount is at least 150% of the maximum potential fine.

Documentation and Disclosure Obligations

The Sponsor’s Due Diligence Plan and the HKEX Submission

The sponsor must document its assessment of the pending investigation in the DD Plan, which is submitted to the HKEX under Listing Rule 3A.02. The DD Plan must include:

• A summary of the regulatory investigation, including the regulator, the legal basis, the alleged breaches, and the stage of the investigation.
• The legal opinion from the applicant’s external counsel, including the likelihood of a penalty and the estimated quantum.
• The sponsor’s own analysis of the financial impact, including sensitivity analysis (e.g., worst-case, base-case, and best-case scenarios).
• The resolution path, including any settlement negotiations or undertakings.

The HKEX’s Listing Decision LD 145-2024 requires the sponsor to file the DD Plan at least 10 business days before the listing hearing. The HKEX may request additional information, including a “sponsor’s confirmation” that the applicant has adequate financial resources to pay the penalty. The sponsor must respond within 5 business days.

Prospectus Disclosure Requirements

The prospectus must disclose the investigation in the “Risk Factors” section, but the level of detail is critical. The SFC’s Statement on Sponsor Due Diligence (2024) states that a generic statement such as “the applicant is subject to a regulatory investigation” is insufficient. The sponsor must disclose:

• The name of the regulator and the legal basis for the investigation.
• The nature of the alleged breaches and the maximum penalty under the relevant ordinance.
• The applicant’s response and any settlement discussions.
• The potential impact on the applicant’s financial condition, including a quantified estimate if available.

In the SFC v. Merrill Lynch case (2023), the SFC found that the sponsor’s disclosure of the investigation in a single sentence in the risk factors was “materially misleading” because it did not disclose the potential fine of HKD 12.5 million. The SFC fined the sponsor HKD 4 million for this failure.

Ongoing Obligations After Listing

Even if the investigation is resolved before listing, the sponsor must consider whether the applicant has any ongoing obligations. Under Listing Rule 13.09, the applicant must disclose any material regulatory action after listing. The sponsor should include a condition in the sponsor agreement requiring the applicant to notify the sponsor of any developments in the investigation for at least 12 months after listing. The SFC’s Code of Conduct paragraph 17.6(d) requires the sponsor to “take reasonable steps to ensure that the listing document remains accurate and complete up to the time of listing,” which includes monitoring the investigation.

Case Studies and Recent Enforcement Actions

SFC v. Merrill Lynch Far East Limited (2023)

The SFC’s disciplinary action against Merrill Lynch is the most instructive case for sponsors. The applicant was a Hong Kong-incorporated company applying for a Main Board listing. The applicant had received a letter from the HKMA in 2022 indicating that it was investigating potential breaches of the Banking Ordinance (Cap. 155) relating to anti-money laundering (AML) controls. The HKMA’s letter stated that the maximum fine was HKD 5 million per breach, and the applicant had three potential breaches.

The sponsor’s due diligence team obtained the letter but did not obtain a legal opinion on the quantum of the penalty. The sponsor’s internal DD Plan noted the investigation in a single line: “Applicant is subject to HKMA investigation – see legal counsel.” The legal counsel’s opinion stated that the investigation was “at an early stage” and that “no penalty is expected to be material.” The sponsor accepted this without further enquiry.

The SFC found that the sponsor failed to meet the standard of reasonable enquiries under paragraph 17.6(b) of the Code. The SFC noted that the legal opinion was “vague and unsubstantiated” and that the sponsor should have requested a detailed analysis of the potential penalty, including a range of scenarios. The SFC imposed a fine of HKD 4 million and suspended the sponsor’s licence for 12 months.

HKEX Listing Decision LD 145-2024 (December 2024)

This decision involved a Main Board applicant that had an outstanding penalty of HKD 8.3 million from the Competition Commission for anti-competitive conduct. The applicant had not disclosed this penalty in its A1 filing. The HKEX discovered the penalty during its vetting process and requested the sponsor to provide a DD Plan addressing the issue.

The sponsor’s DD Plan included a legal opinion from the applicant’s external counsel stating that the penalty was “not material” because it represented only 2% of the applicant’s net profit of HKD 415 million. However, the HKEX determined that the penalty constituted a “material adverse change” under Listing Rule 9.03(3) because it indicated a systemic compliance failure. The HKEX required the applicant to settle the penalty before the listing hearing and to implement a compliance improvement plan monitored by an external auditor.

The HKEX’s decision underscores that materiality is not solely a financial test. The Exchange will consider the nature of the breach, the regulator’s findings, and the applicant’s remedial actions. The sponsor must document this qualitative analysis in the DD Plan.

Actionable Takeaways for Sponsors

1. Obtain a detailed legal opinion from the applicant’s external counsel at the start of due diligence, specifying the maximum penalty under the relevant ordinance, the likelihood of enforcement, and the estimated quantum, and do not accept a “not material” opinion without supporting analysis.
2. Quantify the financial impact of the investigation in the sponsor’s due diligence plan, including worst-case, base-case, and best-case scenarios, and adjust the applicant’s profit test or market capitalisation test accordingly under Listing Rule 8.05.
3. Engage the regulator proactively by advising the applicant to consider settlement or a deferred prosecution agreement before the listing hearing, and document this engagement in the DD Plan filed with the HKEX under Listing Rule 3A.02.
4. Disclose the investigation in the prospectus with granular detail, including the regulator’s name, the legal basis, the maximum penalty, and the applicant’s response, as required by the SFC’s Statement on Sponsor Due Diligence (2024).
5. Include a post-listing monitoring condition in the sponsor agreement requiring the applicant to notify the sponsor of any developments in the investigation for at least 12 months after listing, and ensure the sponsor’s compliance team reviews these notifications under the SFC’s Code of Conduct paragraph 17.6(d).
