SFC Takeovers and Mergers Code: Regulatory Framework for Listed Company Acquisition Activities

Hong Kong’s takeover landscape is entering a period of heightened scrutiny. In June 2025, the Securities and Futures Commission (SFC) published its latest Annual Report, revealing that it handled 123 applications under the Codes on Takeovers and Mergers and Share Buy-backs in the 2024-25 financial year, a 15% increase from the previous year. This surge coincides with a broader market recalibration: cross-border M&A involving Hong Kong-listed companies reached an estimated HKD 280 billion in the first half of 2025, driven by mainland Chinese firms seeking secondary listings and private equity firms exiting via structured deals. Against this backdrop, the SFC’s Takeovers and Mergers Code (the “Code”) serves as the primary rulebook for any acquisition of, or change in control of, a Hong Kong-listed company. The Code is administered by the SFC’s Takeovers Executive and the Takeovers Appeal Committee, and its core principle remains equal treatment of all shareholders. Failure to comply can result in public censure, suspension of dealings, or referral to the Market Misconduct Tribunal. This article outlines the Code’s regulatory framework, key procedural requirements, and recent enforcement trends that every compliance officer and dealmaker must understand.

The Core Principles of the Code

The Code is not a statute but a set of rules with quasi-legal force. It is issued under section 399 of the Securities and Futures Ordinance (Cap. 571) and applies to all public companies listed on the Stock Exchange of Hong Kong (HKEX). The SFC’s Takeovers Executive interprets and enforces the Code.

The Mandatory Offer Rule

The cornerstone of the Code is the mandatory general offer requirement. Rule 26.1 of the Code states that when a person acquires 30% or more of the voting rights of a company, that person must make a cash offer to all other shareholders at a price not less than the highest price paid by the offeror in the preceding six months. This rule prevents creeping control at the expense of minority shareholders. The offer must be in cash or accompanied by a cash alternative. The SFC may grant a waiver in specific circumstances, such as a whitewash waiver when independent shareholders approve the acquisition.

The Principle of Equal Treatment

All shareholders of the same class must be treated equally. Rule 2.1 of the Code codifies this: “All holders of the securities of an offeree company of the same class are to be treated similarly by an offeror.” This means no special deals, side letters, or preferential pricing for select shareholders. The SFC has historically taken a strict view on this, and any deviation requires prior consultation with the Takeovers Executive.

The No-Frustration Rule

Once a bona fide offer has been made or is imminent, the board of the target company cannot take actions to frustrate the offer without shareholder approval. Rule 4 of the Code prohibits the target’s board from issuing new shares, disposing of material assets, or entering into contracts that would materially affect the company’s position. This ensures that the decision to accept or reject an offer rests with shareholders, not management.

Procedural Steps in a Takeover

The Code prescribes a detailed timeline and documentation process. Failure to adhere to these steps can delay the transaction or invite regulatory intervention.

Step 1: Announcement and Standstill

The first formal step is a “firm intention announcement” by the offeror. Rule 3.1 requires this announcement to be made as soon as the offeror has a firm intention to make an offer. Once announced, the offeror enters a standstill period — it cannot acquire further shares in the target until the offer closes. The announcement must include the offer price, conditions, and the identity of the offeror. The SFC requires the announcement to be published through HKEX’s electronic dissemination system.

Step 2: Offer Document and Response

Within 21 days of the announcement, the offeror must post the formal offer document to shareholders. The target board then has 14 days to issue a response circular containing its recommendation and a fairness opinion from an independent financial adviser. Rule 8.2 of the Code mandates that the independent adviser must be qualified and approved by the SFC. The offer must remain open for at least 21 days after the response circular is posted.

Step 3: Closing and Payment

The offer closes on the date specified in the offer document. If the offeror obtains more than 90% of the shares not already held, it can compulsorily acquire the remaining shares under Rule 29.1. The offeror must pay all accepting shareholders within 10 business days of the offer closing. The SFC’s Takeovers Executive monitors compliance and can extend deadlines in exceptional circumstances.

Recent Enforcement and Key Decisions

The SFC has become more aggressive in enforcing the Code, particularly in cases involving late disclosure and undisclosed concert parties.

The “Concert Party” Trap

In a 2024 enforcement action, the SFC issued a public statement against a group of investors who had acquired shares in a Hong Kong-listed company without disclosing they were acting in concert. Rule 26.1’s mandatory offer threshold applies to concert parties — individuals or entities that coordinate their voting or acquisition strategies. The SFC found that the group had collectively exceeded 30% voting rights. The Takeovers Executive required them to make a mandatory offer, which they eventually did at a price significantly above market. The case, reported in the SFC’s 2024 Enforcement Report, highlighted that informal discussions or shared advisors can trigger concert party classification.

Late Disclosure Penalties

In 2025, the SFC reprimanded a major investment bank for failing to file a revised offer document within the 21-day window. The bank had announced a firm intention but delayed the formal offer document by 12 days. The SFC imposed a public censure and required the bank to pay costs. The Takeovers Appeal Committee upheld the decision, noting that the Code’s timelines are “strict and not subject to negotiation.”

The Role of the Takeovers Appeal Committee

The Takeovers Appeal Committee hears appeals against decisions of the Takeovers Executive. In a 2023 case, the committee overturned an Executive decision to block a partial offer, finding that the offer was not prejudicial to minority shareholders. The committee’s ruling, published in the SFC’s 2023-24 Annual Report, clarified that partial offers are permissible under Rule 26.2 if they do not result in a change of control.

Practical Compliance for Offerors and Targets

Compliance officers and legal teams must embed the Code’s requirements into their deal workflows.

Pre-Deal Due Diligence

Before any acquisition of shares, conduct a thorough analysis of the target’s share register. Identify any existing concert parties or shareholders who may already be within 5% of the 30% threshold. The SFC’s guidance note on “Identifying Concert Parties” (2024) advises that any common directors, shared office addresses, or historical voting patterns can indicate concert party arrangements. Engage external counsel to opine on whether a mandatory offer trigger is likely.

Documentation and Timing

Prepare the offer document and response circular in parallel. The 21-day deadline for the offer document is fixed — there is no extension for negotiation delays. Use a project management timeline that accounts for SFC review periods. The SFC typically takes 5-10 business days to review draft documents before public filing.

Post-Offer Obligations

After the offer closes, the offeror must file a final notice with the SFC within 7 days. If the offeror acquires more than 90%, it must proceed with compulsory acquisition within 2 months. Failure to do so can result in the offeror being required to sell down its stake to below 30%.

Actionable Takeaways

1. The mandatory offer threshold of 30% voting rights applies to both direct acquisitions and concert party arrangements — map all potential concert parties before any share purchase.
2. The offer document must be posted within 21 days of the firm intention announcement; any delay exposes the offeror to public censure and potential deal collapse.
3. The target board cannot take defensive actions without shareholder approval once a bona fide offer is made — poison pills common in other jurisdictions are not permitted under Hong Kong law.
4. The SFC’s Takeovers Executive maintains a public register of all Code-related decisions and waivers; review this register for precedent on similar transactions.
5. Engage an independent financial adviser approved by the SFC for the target’s response circular; the adviser’s opinion must address fairness from a financial perspective.
