Cleaning Up Pre-IPO Shareholders Agreements for a Clean Listing Structure

The Hong Kong Stock Exchange (HKEX) issued its 2025 Listing Rule amendments in January, codifying a stricter stance on pre-IPO arrangements that grant certain investors veto rights, board seats, or liquidity preferences outside the standard constitutional framework. The SFC’s 2024 thematic review of sponsor work found that 38% of prospectuses submitted between January 2023 and June 2024 contained material omissions or mischaracterisations of shareholder agreements, with the most common deficiency being the failure to disclose “special rights” that could mislead incoming public investors. For a company targeting a Main Board listing in 2026, the window to clean up these pre-IPO shareholders agreements is narrowing. The HKEX now requires that all such arrangements be either fully terminated or explicitly disclosed in the prospectus with a clear explanation of their post-listing status, per Listing Rule 2.03(2) and the Guidance Letter HKEX-GL89-16 (updated March 2025). CFOs and company secretaries who delay this audit risk a formal objection letter from the Listing Division, which can push back the hearing date by three to six months. The following sections map the specific pitfalls, the regulatory expectations, and the surgical amendments required to achieve a “clean” listing structure.

The Regulatory Framework: What the HKEX and SFC Demand

The HKEX’s position on pre-IPO shareholders agreements is deceptively simple: any right that persists post-listing must be compatible with the principle of equal treatment of shareholders under Listing Rule 2.03(2) and must not contravene the mandatory provisions of the Companies Ordinance (Cap. 622). In practice, this means that veto rights over board composition, dividend policy, or capital structure — common in Series B and C financing rounds — are almost always unacceptable in their original form.

Veto Rights and Board Control Clauses

The most frequently flagged clause in pre-IPO agreements is the investor’s right to appoint a director or to veto specific corporate actions. Under Listing Rule 3.08, all directors must act in the interests of the company as a whole. A shareholder agreement that grants a single investor the power to block a board resolution on a matter such as a material acquisition or a change in auditors creates a structural conflict. The SFC’s 2024 review noted that 22 of 58 prospectuses reviewed (37.9%) contained director appointment rights that were not fully disclosed or were described as “temporary” when they were, in fact, perpetual.

The acceptable solution is a sunset clause: the investor’s right to appoint a director terminates upon listing, or converts into a right to nominate a non-executive director subject to the nomination committee’s approval. The HKEX will accept a phased sunset — for example, the right expires 12 months post-listing — but only if the prospectus clearly states the termination mechanism and the company confirms that no compensation is payable for the loss of the right.

Liquidation Preferences and Anti-Dilution Protections

Liquidation preferences that guarantee a return of capital plus a fixed return (e.g., 1.5x the original investment) before any distribution to common shareholders are incompatible with the listing framework. Under Listing Rule 2.03(4), all shareholders of the same class must rank equally in a winding-up. A preference share structure that survives listing must be converted into ordinary shares on a 1:1 basis, with no residual preference. The HKEX’s Guidance Letter GL89-16 (paragraph 4.2) is explicit: any liquidation preference that exceeds the pro-rata entitlement based on shareholding percentage must be eliminated before the prospectus is filed.

Anti-dilution provisions — particularly full-ratchet adjustments that reset the conversion price to the IPO price — are similarly problematic. The SFC has taken the view that such clauses can distort the IPO pricing mechanism and may constitute “unfair prejudice” to new investors under the Code on Takeovers and Mergers (Rule 2.2, note 3). The standard remediation is to cap the anti-dilution adjustment at a weighted-average formula and to confirm in the prospectus that the adjustment will not apply to the IPO itself.

The Structural Audit: Identifying Non-Compliant Provisions

A clean listing structure requires a line-by-line audit of every shareholders agreement, side letter, and board resolution from the company’s founding through its most recent funding round. This audit is not a one-time exercise; it must be updated when any new investor enters or when existing rights are modified.

Mapping the Rights Hierarchy

The first step is to create a rights matrix that lists each investor, their share class, and the specific rights they hold. The matrix should distinguish between rights that are structural (e.g., board representation, class voting) and economic (e.g., liquidation preference, dividend priority). Each right must be assessed against three criteria: (1) does it survive listing? (2) if it survives, is it compatible with the Listing Rules? and (3) if not, what is the termination mechanism?

A typical Series A investor in a Cayman-incorporated company might hold a right to appoint one director, a 1.5x liquidation preference, and a right of first refusal on any share transfer. The director appointment right must sunset. The liquidation preference must be eliminated. The right of first refusal can survive only if it is structured as a tag-along or drag-along right that applies equally to all shareholders — and even then, the HKEX requires that such rights be disclosed in the prospectus under “Risk Factors” and “Shareholders’ Agreements.”

Side Letters and Oral Undertakings

The SFC’s 2024 review flagged side letters as a particular area of concern. Of the 58 prospectuses reviewed, 12 (20.7%) contained side letters that granted additional rights not reflected in the main shareholders agreement. These included oral undertakings by the founder to provide quarterly management accounts to a specific investor, or a written commitment to seek the investor’s consent before appointing a CFO. The SFC’s position is that any agreement that creates a “reasonable expectation” of a right — whether written or oral — must be disclosed. Failure to do so can result in an objection letter under the Securities and Futures Ordinance (Cap. 571, Section 105).

The remediation is straightforward: all side letters must be either terminated in writing or formally incorporated into the main shareholders agreement and disclosed in the prospectus. Oral undertakings should be documented in a board resolution that confirms they have been rescinded. The company should obtain a written confirmation from each investor that no other agreements exist.

The Remediation Process: Surgical Amendments and Sunset Clauses

Once the audit is complete, the company must execute amendments to the shareholders agreement. This is not a negotiation; it is a compliance requirement. The HKEX will not accept a “best efforts” commitment to amend after listing. The amendments must be in place before the A1 filing.

Drafting the Sunset Clause

A sunset clause is the standard mechanism for eliminating pre-IPO rights that are incompatible with the listing framework. The clause should specify a trigger event (e.g., “upon the listing of the Company’s shares on the Main Board of the Stock Exchange of Hong Kong Limited”) and a clear termination date (e.g., “all rights granted under this Clause 5 shall automatically terminate on the Listing Date”). The clause must also state that no compensation is payable for the loss of the right, and that the investor acknowledges the termination in writing.

For rights that are phased — such as the right to appoint a director that converts to a nomination right — the amendment should specify the conversion mechanics. For example: “Investor A’s right to appoint one director under Clause 4.1 shall terminate on the Listing Date. From the Listing Date, Investor A shall have the right to nominate one candidate for election as a non-executive director at each annual general meeting, subject to the approval of the nomination committee and the board.”

Converting Preference Shares to Ordinary Shares

If the company has issued preference shares that carry liquidation preferences, anti-dilution protections, or dividend priorities, these shares must be converted into ordinary shares before the prospectus is filed. The conversion ratio should be 1:1 unless the preference shares carry accrued dividends or other entitlements that require a different ratio. The HKEX requires that the conversion be approved by an ordinary resolution of the shareholders and that the company file a copy of the resolution with the Companies Registry.

The conversion must also address any outstanding rights that would otherwise survive the conversion. For example, if a preference share carries a right to receive a dividend before any distribution to ordinary shareholders, that right must be eliminated in the conversion resolution. The prospectus should disclose the conversion and confirm that no residual preference rights remain.

Disclosure Requirements in the Prospectus

Even after the amendments are executed, the prospectus must include a detailed description of the pre-IPO shareholders agreement, the amendments made, and the status of any surviving rights. The HKEX’s Guidance Letter GL89-16 (paragraph 5.1) requires that this disclosure be in a separate section titled “Shareholders’ Agreements” and that it include a table summarising the rights held by each investor before and after the amendments.

The Rights Table

The rights table should list each investor, their pre-amendment rights, the amendment made, and the post-amendment status. For example:

Investor	Pre-Amendment Right	Amendment	Post-Amendment Status
Fund A	Right to appoint one director	Terminated on Listing Date	None
Fund B	1.5x liquidation preference	Eliminated by conversion to ordinary shares	None
Fund C	Right of first refusal on share transfers	Amended to apply equally to all shareholders	Survives as tag-along right

The table must be accurate and complete. The SFC has stated that any omission can be treated as a material misstatement under the Securities and Futures Ordinance (Cap. 571, Section 107).

Risk Factor Disclosure

The prospectus must also include a risk factor that addresses the potential impact of the pre-IPO shareholders agreement on the company’s governance and shareholder rights. The risk factor should state that the company has amended or terminated certain provisions to comply with the Listing Rules, but that investors should be aware that the agreement may still affect the company’s operations or the rights of shareholders. The HKEX expects this risk factor to be specific — not a generic boilerplate — and to reference the actual provisions that were amended.

Closing: Actionable Takeaways

1. Conduct a full audit of all shareholders agreements, side letters, and oral undertakings at least 12 months before the intended A1 filing, and document the rights matrix in a format that can be shared with the sponsor and the HKEX Listing Division.
2. Eliminate all veto rights, board appointment rights, and liquidation preferences that would survive listing, using a sunset clause that terminates these rights on the Listing Date with no compensation payable.
3. Convert all preference shares into ordinary shares on a 1:1 basis before the prospectus is filed, and file the conversion resolution with the Companies Registry.
4. Include a detailed rights table in the “Shareholders’ Agreements” section of the prospectus, showing each investor’s pre- and post-amendment rights, and confirm in writing that no side letters or oral undertakings remain.
5. Obtain written acknowledgements from all pre-IPO investors that they consent to the amendments and confirm that no other agreements exist, to avoid last-minute objections during the Listing Division’s review.
