SFC Code on Share Buy-backs (hong Kong) 2026, Treasury Shares, Approvals and Disclosure

Treasury shares Hong Kong rules changed decisively in recent years, and every listed issuer now needs to understand how the new regime works in practice. For the first time, Main Board and GEM issuers can hold repurchased shares in treasury rather than cancelling them automatically, opening up more flexible capital management. This guide explains the interplay between the Hong Kong Stock Exchange (HKEX) Listing Rules amendments and the Securities and Futures Commission (SFC) Code on Share Buy-backs, setting out the approvals, execution mechanics, public float consequences and disclosure obligations that apply in 2026. It is written for listed issuers, CFOs, general counsel, company secretaries, corporate finance banks and sponsor counsel who must execute buy-backs and manage treasury holdings with confidence.

Executive summary, what issuers must know in 2026

• Treasury shares are now permitted. HKEX amended its Listing Rules so that repurchased shares need no longer be cancelled; they may be held in treasury and later resold, transferred or cancelled, subject to conditions.
• Two regulatory regimes apply in parallel. The SFC Code on Share Buy-backs governs conduct, pricing and reporting, while the HKEX Listing Rules govern authorisation, disclosure and listing consequences. Issuers must satisfy both.
• Public float is directly affected. Shares held in treasury do not count towards the minimum public float, so buy-backs and treasury holdings can erode float and trigger remedial action.
• Disclosure is continuous and time-sensitive. On-market dealings, monthly returns and announcements of material transactions must be filed within prescribed timeframes.
• Takeovers Code interactions matter. A buy-back that increases a controlling shareholder’s percentage can trigger mandatory offer obligations unless a whitewash waiver is obtained.

The sections below set out each of these points in depth, with procedural checklists, scenarios and a comparison table. This article is practical guidance and not a substitute for tailored legal advice on a specific transaction.

Are treasury shares allowed? HKEX amendments, what changed

For many years, Hong Kong-listed issuers that repurchased their own shares were generally required to cancel those shares. That position changed with the HKEX Listing Rules amendments introduced following its consultation on treasury shares. Under the revised framework, an issuer may elect to hold repurchased shares in treasury rather than cancel them, giving boards a reusable pool of shares for future financing, incentive schemes or capital management.

The rationale behind the reform is flexibility and alignment with other major markets. Holding shares in treasury allows an issuer to resell or transfer them later, for example to satisfy share option exercises or to raise capital quickly, without the delay and cost of a fresh issue. The amendments align the Listing Rules with the position already available under general company law and bring Hong Kong into line with jurisdictions where treasury holdings are long established.

The changes apply across Main Board and GEM issuers, with equivalent provisions in the respective rulebooks. Issuers should consult the HKEX consultation conclusions for the precise effective dates, transitional arrangements and the specific rule numbers governing the treasury share mechanics, because the drafting determines exactly how treasury holdings interact with buy-back mandates, disclosure and public float.

Which issuers can use treasury shares?

Eligibility to hold treasury shares in Hong Kong is broadly available to listed issuers, but it is conditional. The issuer’s constitutional documents (such as its articles of association) must permit the holding of treasury shares; where they do not, a constitutional amendment approved by shareholders may be required. The issuer must also have a valid buy-back mandate in place, since shares can only enter treasury if they are first lawfully repurchased under the applicable approval framework.

Issuers incorporated outside Hong Kong, a significant proportion of the listed population, must also ensure that the laws of their place of incorporation permit treasury holdings, because the HKEX rules operate alongside, not instead of, the home-country company law. Where overseas law prohibits or restricts treasury shares, cancellation may remain the only route. Early verification of constitutional and home-jurisdiction capacity is therefore an essential first step.

SFC Code on Share Buy-backs: scope and key obligations

The SFC Code on Share Buy-backs is the primary conduct regime for repurchases by relevant Hong Kong-listed companies. Its purpose is to ensure that buy-backs are carried out fairly, transparently and without manipulating the market or prejudicing shareholders. The Code sets out the permitted methods, the authorisations required and the ongoing reporting obligations.

The Code recognises distinct methods of repurchase, principally on-market buy-backs conducted through the exchange, and off-market buy-backs effected by general offer or on terms approved by shareholders. Each method carries its own approval and disclosure requirements. Where the SFC Code on Share Buy-backs and the HKEX Listing Rules both apply, issuers must comply with each applicable requirement, observing the stricter where they diverge.

In summary, the key issuer obligations include:

1. Authorisation. A buy-back must be authorised by shareholders, typically through a general mandate approved by ordinary resolution at the annual general meeting, within the permitted limit.
2. Method compliance. On-market and off-market repurchases must follow the procedural requirements specified for each route, including shareholder approval for off-market terms.
3. Price restraint. Repurchases must observe the price restrictions designed to prevent market manipulation and inflated pricing.
4. Reporting. Dealings must be reported to the exchange within the prescribed period, and periodic returns must be filed.
5. Dealing restrictions. Buy-backs must not be carried out during prohibited periods, such as when the issuer is in possession of inside information or in the run-up to results announcements.
6. Director conduct. Directors must ensure the repurchase is in the best interests of the company and shareholders as a whole and must not deal improperly in connection with it.

Issuers should always refer to the current SFC Code document for the exact paragraph references and any conditions, as these govern how a defence to market misconduct may be established.

Price and volume limits under the SFC Code

The regime constrains both the price at which an issuer may repurchase and, through the Listing Rules, the volume it may repurchase. Price restraints prevent an issuer from paying excessively above the prevailing market price, which protects remaining shareholders and reduces the risk of artificial price support. Volume limits, expressed through the general mandate cap on the number of shares repurchasable in the authorisation period, ensure that repurchases remain proportionate and that public float is not eroded too quickly.

Breaching these limits is a serious matter. Exceeding the authorised volume without fresh shareholder approval renders the repurchase unauthorised, while paying beyond any permitted price limit can expose directors and the issuer to regulatory action. Compliance monitoring during an active buy-back programme is therefore not optional; it should be built into the company secretary’s and broker’s day-to-day execution checks.

HKEX Listing Rules: treatment of treasury shares and listing consequences

Once repurchased shares are held in treasury rather than cancelled, the HKEX Listing Rules govern how they are treated for the duration of the holding. The central principle is that treasury shares are not treated as outstanding shares held by the public. While they remain held by the issuer or on its behalf, they confer no economic or governance benefit on the issuer itself.

In practical terms, treasury shares generally carry no voting rights while held in treasury, and no dividends or other distributions are paid on them. This prevents an issuer from manipulating control or inflating distributions through its own holdings. Crucially, treasury shares do not count towards the minimum public float, because they are not held by public shareholders. This is one of the most important consequences of the regime for capital planning, and it is addressed in detail in the public float section below.

The treatment of treasury shares also has implications for share capital entries. Issuers must keep their share register and public disclosures accurate to reflect the number of shares held in treasury at any time, and should ensure per-share metrics are calculated consistently with the applicable accounting standards.

Return to market, sale or cancellation of treasury shares

Treasury shares can be dealt with in three principal ways: resold or transferred back into the market, used to satisfy obligations such as share schemes, or ultimately cancelled. The HKEX Listing Rules treat the resale of treasury shares in a manner analogous to a fresh issue of new shares, because the effect on the market and on existing shareholders is similar, shares that were out of public hands return to circulation.

As a result, resales of treasury shares attract issue-style requirements. These can include the need for a valid issue mandate, compliance with pricing and dilution restrictions, and appropriate disclosure. Where treasury shares are resold at a discount, the usual restrictions on discounted issues are relevant. Where treasury shares are cancelled instead, the holding is extinguished and the issued share capital is adjusted accordingly, with the attendant register and filing updates. Issuers should plan the exit route for treasury shares at the outset, because the approval and disclosure consequences differ materially between resale and cancellation.

Approvals and governance: board, shareholders, HKEX and SFC

Executing a buy-back lawfully requires layered approvals. The board must resolve to carry out the repurchase and must be satisfied it is in the company’s interests. Shareholders must grant authority, usually through a general mandate. Depending on the method, the exchange and the SFC also have roles. The approval structure differs between on-market and off-market repurchases, and the treasury share election adds a further layer.

On-market buy-backs: procedural checklist

An on-market buy-back is conducted through trading on the exchange at prevailing market prices. It is the most common and flexible route for a treasury shares Hong Kong programme. The typical sequence is:

• Confirm the mandate. Ensure a valid general mandate authorising repurchases exists and that the proposed volume falls within the permitted cap.
• Board resolution. Pass a board resolution approving the repurchase, confirming compliance with the Code and Listing Rules, and (if applicable) electing to hold shares in treasury.
• Check dealing windows. Verify the issuer is not in a prohibited period and holds no undisclosed inside information.
• Instruct the broker. Engage a broker with clear instructions on price limits, daily volume and the duration of the programme.
• Execute within limits. Repurchase on-market, observing price and volume restrictions throughout.
• Report dealings. File the required report of each repurchase with the exchange within the prescribed time.
• Update the register. Record the shares as held in treasury or as cancelled, and update share capital figures.

Off-market buy-backs, tenders and repurchases on terms

An off-market buy-back takes place outside ordinary exchange trading, for example by a general offer to all shareholders, by tender, or by agreement on specific terms with particular holders. Because off-market repurchases can favour selected shareholders or be priced away from the market, they attract heightened scrutiny. The SFC Code requires shareholder approval for off-market repurchase terms, typically by special resolution, and the approval of disinterested shareholders where connected parties are involved.

Off-market routes are slower and more procedurally intensive than on-market buy-backs, usually requiring a shareholders’ circular, independent advice and a general meeting. Where the repurchase would materially increase the percentage holding of a controlling or significant shareholder, a whitewash waiver under the Takeovers Code may be required to avoid triggering a mandatory general offer. Issuers contemplating an off-market or tender repurchase should build in a longer timetable and early engagement with advisers.

Shareholder mandates and standard resolution wording

The foundation of most buy-back programmes is the general mandate, an ordinary resolution passed at the annual general meeting authorising directors to repurchase shares up to a specified percentage of issued shares during the authorisation period. The mandate should be drafted to cover the permitted method, the maximum number of shares, and the ability to hold repurchased shares in treasury where the issuer intends to use that route.

Well-drafted resolution wording references the applicable Listing Rule limits, confirms the repurchase authority runs until the next annual general meeting (or earlier termination as provided), and expressly authorises the directors to do all things necessary to give effect to the repurchase and any treasury election. The accompanying explanatory statement to shareholders should set out the reasons for seeking the mandate and the potential effect on public float. Board minutes should record the directors’ consideration of the company’s financial position and the interests of shareholders as a whole.

Execution mechanics: market process, broker instructions and custody for treasury shares

Beyond approvals, a buy-back is an operational exercise involving brokers, the clearing system and the share register. Getting the mechanics right is essential to avoid breaches of price or volume limits and to ensure treasury holdings are correctly recorded.

Execution begins with engaging a broker and giving precise written instructions covering the maximum price, daily and aggregate volume, and the period over which repurchases may be made. The broker executes repurchases on the exchange within those parameters. Trades settle through the Central Clearing and Settlement System (CCASS), and the issuer must ensure that settlement arrangements correctly route the repurchased shares into the issuer’s account or a nominee account where they are to be held in treasury.

Settlement and custody: practical steps

Where shares are to be held in treasury rather than cancelled, custody arrangements require particular attention. The repurchased shares must be held in a manner that reflects their treasury status, carrying no voting rights and no entitlement to distributions while held. The issuer should confirm custodian instructions in advance so that treasury shares are segregated and clearly identified on the register and in CCASS records.

Practical steps include: confirming the account into which treasury shares will settle; instructing the share registrar to update the register to reflect the shares as held in treasury; suspending voting and dividend entitlements on those shares; and reconciling the treasury holding regularly against repurchase reports. When treasury shares are later resold or cancelled, these records must be updated again, and any appropriate filings made with the Companies Registry to reflect the change in issued share capital or the movement of shares out of treasury.

Public float and capital management: five practical scenarios

Because treasury shares do not count towards the minimum public float, buy-backs and treasury holdings can reduce the proportion of shares in public hands. Every listed issuer must maintain the minimum public float required under the Listing Rules, and breaching it can lead to suspension of trading or, ultimately, delisting. The following scenarios illustrate the risk and the available remedies.

• Scenario 1, comfortable headroom. An issuer with a public float well above the minimum repurchases a modest number of shares. The float remains above the threshold and no action is required, though the issuer should continue to monitor.
• Scenario 2, approaching the threshold. Repeated repurchases push the public float close to the minimum. The issuer should pause the programme and reassess before the float is breached.
• Scenario 3, breach through treasury accumulation. Shares held in treasury reduce the public-held proportion below the minimum. Remedies include a placing of new or treasury shares to public investors to restore float.
• Scenario 4, concentrated holdings worsen the position. A controlling shareholder’s percentage rises as the public float falls. A share placing or a sale by the controlling shareholder may be needed, and a share consolidation may be considered as part of a wider restructuring.
• Scenario 5, persistent shortfall. The issuer cannot restore float promptly. It may need to engage the exchange and present a clear remediation plan, mindful that prolonged non-compliance risks suspension and delisting.

The remedial toolkit includes placings, rights issues, share consolidations and engagement with the exchange on a remediation plan. The right choice depends on the size of the shortfall, market conditions and the issuer’s wider capital strategy.

Takeover implications of buy-backs

A buy-back reduces the total number of shares in issue, which mathematically increases the percentage held by every shareholder who does not sell into the programme. For a controlling or near-controlling shareholder, this can push a holding across a Takeovers Code threshold and trigger an obligation to make a mandatory general offer. To avoid this, issuers often seek a whitewash waiver from the Executive, which must be approved by independent shareholders. Any issuer running a material buy-back should model the effect on its largest shareholders’ percentages before executing.

Disclosure and continuous obligations, what to file and when

Transparency is central to the buy-back regime. Disclosure of buy-backs in Hong Kong operates through several overlapping obligations, and issuers must file the right information within the prescribed timeframes to remain compliant.

• Dealing reports. Each repurchase must be reported to the exchange within the time specified in the Listing Rules, disclosing the number of shares, prices and whether shares are held in treasury or cancelled.
• Monthly returns. Issuers file a monthly return of share movements, including repurchases and any changes to treasury holdings.
• Price-sensitive announcements. Where a buy-back or treasury decision is material or involves inside information, a timely announcement is required under the inside information disclosure regime in Part XIVA of the Securities and Futures Ordinance (Cap. 571).
• Off-market disclosures. Off-market and tender repurchases require a shareholders’ circular containing prescribed information before the relevant general meeting.
• Companies Registry filings. Cancellation of repurchased shares and certain capital changes require filings with the Companies Registry to update the public record of share capital.

Sample announcement wording

Announcements should clearly state the method of repurchase, the number of shares repurchased, the price range, the aggregate consideration, whether the shares are held in treasury or cancelled, and the resulting number of issued shares and shares held in treasury. For example, a dealing announcement might record that the company repurchased a stated number of shares on-market on a given date at prices within a stated range, that the repurchased shares are held in treasury, and the number of shares that remain available under the mandate. Company secretaries should maintain template wording that can be populated quickly after each dealing to meet the reporting deadlines.

Practical red flags, compliance pitfalls and SFC enforcement trends

Buy-back and treasury share programmes carry recurring compliance risks that attract regulatory attention. Awareness of these pitfalls helps issuers avoid enforcement.

• Market manipulation. Repurchasing to support or inflate the share price, particularly around results or corporate events, can constitute market misconduct.
• Dealing on inside information. Repurchasing while in possession of undisclosed price-sensitive information, or during a prohibited period, is a serious breach.
• Exceeding limits. Repurchasing beyond the authorised volume or above permitted prices renders the dealing unauthorised and exposes directors to liability.
• Disclosure failures. Late or incomplete dealing reports, monthly returns or announcements undermine market transparency and invite scrutiny.
• Improper directors’ dealings. Directors or connected persons dealing in the issuer’s shares around a buy-back can raise conflict and misconduct concerns.

The SFC monitors buy-back activity as part of its market supervision function and publishes enforcement outcomes and guidance. Issuers should review current SFC press releases and enforcement publications to understand recent areas of focus, and should treat any regulatory query about dealings as a priority. Prompt remediation, correcting filings, pausing a programme and seeking advice, is far preferable to allowing a breach to compound.

Checklist and playbook for issuers: board to market

The following checklist offers a practical sequence from board approval to post-completion reporting. It is practical guidance and should be adapted to the specifics of each transaction with issuer counsel.

• Confirm the constitutional documents permit buy-backs and, if intended, treasury holdings.
• Verify home-jurisdiction company law allows treasury shares for overseas-incorporated issuers.
• Check that a valid general mandate exists and the proposed volume is within the cap.
• Assess public float headroom before any repurchase.
• Confirm the issuer is not in a prohibited period and holds no inside information.
• Model the effect on major shareholders’ percentages and consider whitewash needs.
• Pass a board resolution approving the repurchase and any treasury election.
• For off-market routes, prepare the circular and convene a general meeting.
• Instruct the broker with clear price, volume and duration limits.
• Execute within the Code price and volume limits.
• Report each dealing to the exchange within the prescribed time.
• Update the share register and treasury records; suspend voting and dividends on treasury shares.
• File monthly returns and any required announcements.
• Make Companies Registry filings on cancellation or relevant capital changes.
• Monitor public float continuously and prepare remedial steps if needed.

Conclusion

The treasury shares Hong Kong regime introduced through the HKEX Listing Rules amendments gives issuers a flexible capital management tool, but it must be used within a careful framework of approvals, execution discipline and disclosure. Both the HKEX Listing Rules and the SFC Code on Share Buy-backs apply in parallel, and public float, Takeovers Code and continuous disclosure obligations must all be managed in real time. Issuers who confirm their constitutional and mandate position, model public float and takeover effects, and maintain accurate records and timely filings will be well placed to capture the benefits of treasury holdings while staying compliant.

Because each transaction turns on its own facts, issuers should obtain tailored legal advice before executing a buy-back or treasury share programme in Hong Kong.
