How to Make a Voluntary General Offer in Hong Kong (2026): Timing, Takeovers Code Obligations and Avoiding Mandatory Offer Triggers

Understanding how to make a voluntary general offer in Hong Kong is essential for any bidder seeking to acquire control of a publicly listed company on the Stock Exchange of Hong Kong (HKEX) without first tripping a mandatory offer obligation. A voluntary general offer (VGO) allows an offeror to set its own terms, including price, conditions and timing, while remaining subject to the Securities and Futures Commission’s Codes on Takeovers and Mergers and Share Buy-backs (the “Takeovers Code”). In the 2026 M&A environment, heightened regulatory focus on disclosure, tax transparency and acting-in-concert arrangements means that meticulous pre-offer planning has never been more important.

This guide provides a step-by-step operational playbook, from assembling the deal team through to compulsory acquisition, designed for in-house counsel, corporate development teams and external advisers preparing a VGO in Hong Kong.

1. What a Voluntary General Offer Is and When Bidders Use It

A voluntary general offer is an offer made by a bidder (the “offeror”) to acquire all outstanding shares of a company listed on HKEX, initiated by choice rather than by regulatory compulsion. Unlike a mandatory general offer, which is triggered when a person acquires 30% or more of a company’s voting rights under Rule 26.1 of the Takeovers Code, a VGO is launched proactively, typically when the offeror holds less than the 30% threshold or wishes to acquire full control on favourable terms.

Bidders choose a VGO over other acquisition routes for several reasons: it permits conditional offers (subject to a minimum acceptance level), it allows price flexibility, and it avoids the prescriptive terms imposed on mandatory offers. A VGO is also the preferred route when a bidder wants to test shareholder appetite before committing to full acquisition. That said, a VGO still requires strict compliance with every applicable provision of the Takeovers Code, including equal treatment of shareholders, disclosure obligations and timetable rules.

Before proceeding, every offeror should confirm three essentials:

• Regulatory clearance path. Consult the SFC Executive early and appoint a financial adviser acceptable to the Takeovers Panel.
• Financing certainty. The offeror must be able to demonstrate that it has, or will have, the resources to satisfy full acceptance of the offer.
• Mandatory offer risk assessment. Confirm that neither the offeror nor any concert party has inadvertently crossed, or will cross, the 30% threshold before announcing the VGO.

2. Pre-Offer Planning: Decisions, Due Diligence and Mandatory-Offer Risk Assessment

2.1 Who Should Be on the Deal Team

A well-structured VGO requires coordinated input from multiple advisers. At minimum, the offeror should engage Hong Kong legal counsel experienced in the Takeovers Code, a financial adviser (typically an SFC-licensed corporation), tax advisers familiar with both the offeror’s home jurisdiction and Hong Kong stamp duty implications, and a public relations adviser to manage market communications. For cross-border bidders, local counsel in the offeror’s home jurisdiction is also essential to address foreign regulatory approvals and antitrust considerations. Experienced Hong Kong M&A lawyers will be critical throughout the process.

2.2 Due Diligence and Tax Transparency Checks

Pre-offer due diligence in a VGO context differs from a private M&A transaction. Because the target is listed, access to non-public information is restricted, the offeror must typically rely on publicly available materials unless the target board cooperates by granting access under a confidentiality agreement. In 2026, regulators are placing increased emphasis on tax transparency, meaning offerors should verify the target’s tax positions, transfer pricing arrangements and any outstanding tax disputes as part of their public-record analysis. The offeror must also ensure that no insider dealing occurs: any person in possession of material non-public information about the proposed offer must refrain from dealing in the target’s securities.

2.3 Acceptance Condition Decisions and Sample Wording

The VGO acceptance condition is the single most important commercial term an offeror controls. Most voluntary conditional general offers are made subject to receiving valid acceptances that, together with shares already owned by the offeror and its concert parties, represent more than 50% of the voting rights in the target company. This threshold gives the offeror statutory control. Where the offeror seeks to delist the target or exercise compulsory acquisition rights, a 90% acceptance threshold is standard.

Under the Takeovers Code, an offeror may set any acceptance condition it wishes, but the condition must be clearly stated in the offer document and may only be waived downward (not upward) unless the original terms permit otherwise. Industry observers expect that acceptance conditions set above 50% but below 90% will become more common as bidders balance control objectives against the risk of offer failure.

A sample acceptance condition clause might read:

“This Offer is conditional upon the Offeror having received, by the Closing Date, valid acceptances in respect of such number of Offer Shares which, together with the Shares already owned or agreed to be acquired by the Offeror and parties acting in concert with it, represent more than 50% of the voting rights in the Company as at the Closing Date.”

The offeror should also include a waiver provision: “The Offeror reserves the right to waive the Acceptance Condition, subject to the Offeror and its concert parties holding not less than [X]% of the voting rights in the Company.”

3. Mandatory Offer Trigger Rules, Rule 26.1 and Related Rules

Before structuring a voluntary general offer in Hong Kong, every bidder must understand the mandatory offer triggers that could convert a voluntary process into a compulsory one, or expose the offeror to SFC enforcement action.

3.1 Rule 26.1 Explained

Rule 26.1 of the Takeovers Code provides that when any person (or two or more persons acting in concert) acquires 30% or more of the voting rights in a company, that person is obliged to make a mandatory general offer to all remaining shareholders. The mandatory general offer in Hong Kong must be unconditional (except as to acceptances) and at a price not less than the highest price paid by the offeror or its concert parties for the target’s shares during the six months preceding the announcement. This is not optional: failure to comply constitutes a breach of the Takeovers Code and can result in SFC disciplinary proceedings, cold-shouldering orders and other sanctions.

3.2 Acting-in-Concert and Attribution

The Takeovers Code defines “acting in concert” broadly. Persons are presumed to be acting in concert if they cooperate to obtain or consolidate control of a company through the acquisition of voting rights. The Code sets out specific categories of presumed concert parties, including a company and its directors, a company and its parent, and an offeror and its financial adviser. Holdings of all concert parties are aggregated when assessing whether the 30% threshold has been crossed. Under the acting in concert provisions of the Takeover Code, even informal arrangements, such as a shared understanding about voting or acquisition strategy, can trigger aggregation. The practical consequence is that offerors must conduct a thorough concert-party mapping exercise before any share purchase.

3.3 Creeper Rule and Monitoring

Separately from the 30% trigger, the Takeovers Code contains a “creeper” rule: where a person (together with concert parties) already holds between 30% and 50% of the voting rights, that person may not acquire more than 2% of voting rights in any 12-month period without triggering a mandatory offer obligation. This rule catches incremental stake-building and requires continuous monitoring. Offerors already holding a significant minority stake should maintain a real-time log of all acquisitions (including shares acquired through exercise of options, convertible instruments or scrip dividends) and seek legal advice before each incremental purchase.

4. Takeovers Code Obligations When Making a Voluntary General Offer

Once the decision to proceed with a VGO is made, the offeror must comply with a series of Takeovers Code obligations covering announcements, document preparation, independent advice and ongoing offeror disclosure obligations.

4.1 Announcement and Publication Requirements

The Takeovers Code requires that when a firm intention to make an offer is announced, the announcement must be made through HKEX (via HKEXnews) and must contain specified information including the identity of the offeror and its concert parties, the terms of the offer, details of existing holdings, the financial adviser’s confirmation of resources, and any conditions to which the offer is subject. The target company must also publish a responsive announcement. The offeror should be aware that once an announcement of firm intention is made, the offeror is generally bound to proceed with the offer unless a pre-condition (permitted by the Takeovers Code) has not been satisfied or waived.

Premature disclosure or market rumour may also require an earlier announcement, the SFC Executive may direct the parties to make an announcement at any time where it considers the market to be affected by rumour or unusual trading activity.

4.2 The Firm Intention Announcement and Responsive Announcements

The firm intention announcement is the critical commitment point. It must include the offer price, the consideration structure (cash, shares or a combination), the acceptance condition, and confirmation from the offeror’s financial adviser that sufficient resources are available. Following the firm intention announcement, the target’s board must form an independent board committee (IBC) comprising non-executive directors who are independent of the offeror. The IBC must appoint an independent financial adviser (IFA) to advise the target’s shareholders on whether the offer is fair and reasonable. The IFA’s recommendation is included in the target’s board circular.

4.3 Circular Contents and Regulator Expectations

The offeror must despatch an offer document (circular) to shareholders within prescribed timeframes, typically within 21 days of the firm intention announcement, although extensions may be sought from the SFC Executive in complex transactions. The offer document must contain a letter from the offeror setting out the full terms of the offer, financial information about the offeror, details of the offeror’s intentions for the target’s business and employees, an acceptance form, and information about the acceptance condition and settlement mechanics. The target board circular, containing the IFA’s opinion, must be despatched to shareholders no later than 14 days after the despatch of the offer document. Regulators in 2026 are examining circulars with particular scrutiny for accuracy and completeness of disclosure.

4.4 Offer Finance and Solvency Confirmations

Under the Takeovers Code, before the firm intention announcement is published, the offeror’s financial adviser must confirm to the SFC Executive that sufficient resources are available to the offeror to satisfy full acceptance of the offer. This “cash confirmation” is a fundamental safeguard for target shareholders. The financial adviser must be satisfied, on reasonable grounds, that the offeror will be able to implement the offer in full. Where the consideration is financed by debt, the financial adviser must have reviewed the lending commitments and satisfied itself of their enforceability.

5. Offer Mechanics and Timing: The HKEX General Offer Timeline

Getting the HKEX general offer timeline right is one of the most operationally demanding aspects of a VGO. Delays or missed deadlines can result in SFC censure, loss of shareholder confidence, or outright offer failure.

5.1 Typical Timetable for a Voluntary Conditional General Offer

The following table sets out the key milestones and regulatory timeframes for a typical voluntary conditional general offer in Hong Kong. All day counts below are calendar days unless otherwise indicated.

5.2 Acceptance Period Mechanics and Settlement

During the acceptance period, shareholders submit acceptance forms (and, where applicable, share certificates or transfer documents) to the offeror’s receiving agent. The Takeovers Code requires the offeror to announce the level of acceptances received promptly, in practice, updates are published via HKEXnews at each closing date and at any time the acceptance condition is satisfied. Once the offer is declared unconditional as to acceptances, it must remain open for at least a further 14 days to give remaining shareholders the opportunity to accept.

Settlement of consideration to accepting shareholders must occur within seven business days of the later of: (a) the date of receipt of a valid acceptance, or (b) the date on which the offer becomes or is declared unconditional. Offerors must ensure registrar capacity and funding availability to meet these settlement deadlines without delay.

6. Drafting: Acceptance Conditions, Waiver Clauses and Common Negotiation Points

6.1 Sample Acceptance Condition Wording

Precise drafting of the VGO acceptance condition is critical. The condition should clearly specify the minimum acceptance level, the method of calculation (whether by reference to voting rights or issued share capital), and the treatment of shares already held by concert parties. It should also address the treatment of shares issued during the offer period (for example, shares arising from the exercise of share options). A well-drafted condition for a voluntary conditional general offer typically reads:

“The Offer shall be conditional upon valid acceptances being received (and not, where permitted, withdrawn) by no later than 4:00 p.m. on the Closing Date in respect of such number of Offer Shares which, together with the Shares already owned or agreed to be acquired by the Offeror and parties acting in concert with it, will result in the Offeror and its concert parties holding more than [50/90]% of the voting rights of the Company.”

6.2 Financing and Closing Mechanics

Unlike in some other jurisdictions, the Takeovers Code does not permit a financing condition, the offeror cannot make the offer conditional on obtaining debt or equity financing. The financial adviser’s cash confirmation, provided before the firm intention announcement, substitutes for a financing condition. This means that all funding must be committed and available before Day 0. For cash offers, the offeror should have executed facility agreements with irrevocable lending commitments. For share-exchange offers, regulatory approvals for the issuance of consideration shares must be substantially progressed.

Common negotiation points in practice include the treatment of dividend entitlements during the offer period, the allocation of stamp duty costs (typically borne by the offeror for transferee duty), and undertakings from major shareholders to accept (or not accept) the offer. Irrevocable undertakings from significant shareholders to accept the offer, while not required by the Takeovers Code, are common in practice and can provide the offeror with greater certainty of reaching the acceptance condition. Specialist Hong Kong legal advisers can assist with structuring these undertakings to comply with Takeovers Code requirements.

7. Avoiding Common Traps and Enforcement Risk: A Practical Checklist

Enforcement action by the SFC under the Takeovers Code can result in public censure, cold-shouldering (where market participants are directed not to act for the offender) and referral for criminal prosecution in serious cases. The following checklist highlights the most common traps when making a voluntary general offer in Hong Kong.

Key additional points to monitor:

• Insider dealing. Ensure all persons aware of the proposed offer are logged and subject to dealing restrictions until the announcement is published.
• Post-offer disclosure. The offeror must disclose all dealings in the target’s shares (and derivatives) during the offer period, by 12:00 noon on the business day following the dealing.
• Partial stake purchases. Pre-offer share purchases must be carefully calibrated to remain below the 30% threshold (and below the creeper limit if applicable).
• Equal treatment. All shareholders of the same class must be offered the same terms, any side deal or special arrangement with a particular shareholder may breach the Takeovers Code.

8. Post-Offer Steps: Completion, Compulsory Acquisition and Delisting Considerations

Once the offer closes and the offeror has achieved the desired acceptance level, several post-offer steps follow. If the offeror and its concert parties hold 90% or more of the disinterested shares (that is, shares not already held at the time the offer was made), the offeror may exercise compulsory acquisition rights under section 674 of the Companies Ordinance (Cap. 622). This allows the offeror to acquire the remaining shares on the same terms as the offer, removing minority shareholders and achieving 100% ownership.

Where full ownership is achieved, the offeror typically applies to HKEX for withdrawal of the listing (delisting). HKEX delisting rules require that the offeror give adequate notice to remaining shareholders and comply with any conditions imposed by the Exchange. Even where the 90% threshold is not reached, an offeror holding more than 75% may be able to procure delisting through a scheme of arrangement or privatisation proposal, subject to separate shareholder approval requirements and court sanction. Consult the Hong Kong lawyer directory for specialists experienced in post-offer restructuring and delisting procedures.

9. Practical Worked Example: 2026 VGO Sample Scenario

Consider an offeror (“AcquireCo”) that holds an 18% stake in a Hong Kong-listed target (“TargetCo”). AcquireCo decides to launch a voluntary conditional general offer at a 25% premium to the undisturbed share price, with an acceptance condition set at more than 50% of voting rights.

Week 1–3 (pre-announcement): AcquireCo assembles its deal team, Hong Kong legal counsel, a financial adviser, tax advisers and a PR firm. The financial adviser begins due diligence on AcquireCo’s funding capacity. Legal counsel maps all potential concert parties and confirms AcquireCo’s aggregate holding (including concert parties) is 18%, well below 30%. AcquireCo’s board resolves to proceed and the financial adviser provides the cash confirmation to the SFC Executive.

Day 0: The firm intention announcement is published on HKEXnews, disclosing all required details. TargetCo’s board forms an IBC and appoints an IFA.

Day 0 + 21: The offer document is despatched to shareholders. The acceptance period opens.

Day 0 + 35: TargetCo’s board circular (with IFA recommendation) is despatched.

Day 0 + 42 (first closing date): AcquireCo announces that acceptances received, together with its existing 18% holding, represent 62% of voting rights. The acceptance condition is satisfied and the offer is declared unconditional as to acceptances.

Day 0 + 56: The offer closes after the further 14-day period. Final acceptance level is 78%. AcquireCo settles consideration to all accepting shareholders within seven business days. AcquireCo does not reach 90%, so compulsory acquisition is not available, but AcquireCo holds effective control and considers future options for privatisation.

Conclusion

Knowing how to make a voluntary general offer in Hong Kong requires mastery of the Takeovers Code, disciplined pre-offer planning and airtight execution from announcement through to settlement. The 2026 regulatory climate demands enhanced transparency, rigorous concert-party analysis and flawless adherence to timetable obligations. By following the step-by-step framework set out in this guide, from deal team assembly and mandatory-offer risk assessment through to acceptance condition drafting, HKEX filing deadlines and post-offer compulsory acquisition, bidders can approach a VGO with confidence and minimise enforcement risk.
