Treasury Shares in Hong Kong

Why this matters now

For decades, Hong Kong's listed companies operated under a structural disadvantage that their peers incorporated in the Cayman Islands or Bermuda did not: shares repurchased by an issuer had to be cancelled immediately and permanently. There was no middle ground. No flexibility to hold them, redeploy them strategically, or use them as currency in future transactions. The mandatory cancellation rule effectively treated every buyback as a one-way, irreversible decision.

That constraint has now been dismantled.

In a two-stage legislative sequence — the HKEX Listing Rules amendments effective 11 June 2024, followed by the Companies (Amendment) Ordinance 2025 effective 17 April 2025 — Hong Kong has introduced a fully operational treasury share regime for listed companies. The reform closes a long-standing competitive gap with Cayman Islands and Bermuda incorporated issuers and fundamentally changes the strategic calculus for capital management, M&A structuring, employee incentive programmes, and capital raising.

For decision-makers, the question is no longer whether treasury shares are available as a tool. It is how to use them well — and what governance obligations accompany that flexibility.

The legislative timeline

The treasury share regime did not arrive overnight. Understanding the sequencing matters, because the gap between the two legislative acts created a transitional asymmetry that still has practical relevance for governance planning today.

The critical distinction: over 90 percent of HKEX-listed companies are incorporated in jurisdictions — primarily Cayman Islands and Bermuda — that already permitted treasury shares under local company law. These companies benefited from the Listing Rules reform as of 11 June 2024. Hong Kong-incorporated listed companies, however, had to wait for the Amendment Ordinance to take effect on 17 April 2025 before they could participate in the regime.

For privately-held and unlisted companies incorporated under the Companies Ordinance (Cap. 622), the position remains unchanged: repurchased or redeemed shares are automatically cancelled under Section 269. The treasury share regime is exclusively a listed company benefit.

What treasury shares are

A treasury share is a share that a listed company has repurchased and chosen to retain, rather than cancel. It exists in a legal holding state: it remains part of the company's total issued share capital under certain disclosure frameworks but sits dormant, with key shareholder rights suspended. It can subsequently be cancelled, sold back into the market, transferred as consideration in an acquisition, or deployed to satisfy employee share schemes.

What treasury shares are not is a mechanism for the company to exercise influence over itself. Rights attached to treasury shares — voting, dividends, and distributions — are suspended for so long as those shares remain in treasury. A listed company holding treasury shares cannot use them to shift control dynamics or manufacture consent at shareholder meetings.

This distinction is central to how the HKEX structured the regime's risk safeguards, which are as important for governance-minded boards to understand as the flexibility features themselves.

What boards must know

Holding and custody

A listed company may hold treasury shares in its own name or through a nominee. Where shares are deposited into CCASS (the Central Clearing and Settlement System), they are treated as treasury shares for Listing Rules purposes. However, companies must implement specific interim measures — such as instructing their broker not to vote those shares at general meetings — to ensure rights remain suspended during the period of CCASS holding.

For Hong Kong-incorporated listed companies, a return in the specified form must be filed with the Registrar of Companies within 15 days of any disposal of treasury shares.

Importantly, if a listed company subsequently becomes delisted, all treasury shares it holds are automatically cancelled upon delisting. This is not a discretionary choice — it is a statutory consequence.

Resale mechanics

The Listing Rules treat a resale of treasury shares in broadly the same manner as a new share issuance. This symmetry is intentional: it preserves existing shareholder protection frameworks without requiring an entirely new set of rules. The key operational requirements are as follows:

• Mandate requirement: Resales of treasury shares require either a specific mandate (shareholder-approved on a transaction-specific basis) or a general mandate (typically granted at AGMs). General mandates must expressly authorise treasury share resales — companies relying on legacy general mandate wording that does not reference treasury shares will need to update their resolutions.
• General mandate limit: The combined capacity to issue new shares and resell treasury shares under a general mandate is capped at 20% of issued share capital in any 12-month period, increased by shares repurchased (up to the 10% buyback mandate limit).
• Price discount limit: On-market resales under a general mandate cannot be at a discount of 20% or more relative to the higher of (i) the closing price on the trading day immediately prior to resale and (ii) the average closing price over the five preceding trading days. Off-market resales for cash consideration are subject to equivalent price discipline.
• Pre-emption: Resales not conducted on a pro-rata basis to all shareholders must be mandated in advance, mirroring the requirements for new share placements under Rule 13.36.

The 30-day moratorium: a critical governance tripwire

The rule most likely to catch boards off-guard is the bidirectional 30-day moratorium:

• A company may not resell treasury shares for 30 days after an on-market share repurchase.
• A company may not repurchase shares on-market for 30 days after an on-market resale of treasury shares.

This moratorium is designed to prevent the kind of rapid buy-sell cycling that could be used for market manipulation. There are carve-outs — capitalisation issues (bonus shares, scrip dividends), grants of share awards or options under share schemes, and vesting or exercise of those awards — but these are specific and narrow.

Any capital management calendar that involves both buybacks and treasury share resales in close succession must account for this restriction at the planning stage, not after the fact.

Additionally, on-market resales of treasury shares are prohibited during the 30-day period preceding a results announcement — the same blackout window that applies to on-market repurchases. Boards should ensure this is explicitly embedded in their dealing policies.

New listing applicants

Companies that hold treasury shares at the time of their IPO face an additional restriction: they may not resell any treasury shares within six months after listing. Full disclosure of treasury share holdings is required in the IPO prospectus.

Rights, disclosure, and the SFO dimension

While in treasury, shares cannot:

• Vote at general meetings (under the Listing Rules, the holder must abstain from voting on matters requiring shareholder approval)
• Receive dividends or distributions (companies must withdraw treasury shares from CCASS and either re-register them or cancel them before the record date for any dividend)
• Be treated as disinterested shares under the Takeovers Code

The Takeovers Code carves out treasury shares from the definition of "voting rights," meaning they do not count toward the 30% mandatory general offer trigger or other thresholds under the Codes. This is a meaningful structural point for any party evaluating control transactions involving a company with a material treasury share holding.

Disclosure of interests under part XV SFO

This is where the rules diverge in a counterintuitive direction. Despite the suspension of voting rights, treasury shares remain part of the issuer's issued voting shares for the purpose of shareholder disclosure calculations under Part XV of the Securities and Futures Ordinance. Substantial shareholders are required to compute their percentage holdings on a denominator that includes treasury shares, consistent with the position that has always applied to non-Hong Kong incorporated companies.

The practical implication: a company that conducts a significant buyback and retains shares in treasury will not dilute the denominator used in shareholder disclosure calculations — and institutional investors must factor this into their threshold monitoring.

Stamp duty

A resale of treasury shares is a disposal of shares for valuable consideration and therefore triggers ad valorem stamp duty under the Stamp Duty Ordinance (Cap. 117). This is a meaningful cost differential compared to a fresh issuance of new shares, which does not attract stamp duty in the same way. For structuring purposes — particularly when treasury shares are being deployed as consideration shares in an acquisition — boards and advisers should factor duty costs into the economic analysis early.

Connected person restrictions

Resales to connected people are restricted and subject to additional scrutiny. Any transaction involving a connected person will need to comply with connected transaction requirements under the Listing Rules, including independent shareholder approval where applicable.

Where treasury shares create real value

The reform's significance lies not in its technical mechanics but in what it enables strategically. There are four use cases where treasury shares create tangible competitive advantages:

• Capital-Efficient Fund-Raising A company that has accumulated treasury shares during periods of perceived undervaluation can resell them in small lots at or near market price when conditions improve — without the dilution discount typically required for a placement of new shares. This is a meaningful capability advantage over the pre-2024 framework, which required a full formal share issuance process regardless of context.
• Consideration Shares in M&A Using treasury shares as acquisition currency avoids the time and administrative burden of a formal new share issuance while providing sellers with an immediately marketable, listed instrument. For deal-intensive companies, a treasury share holding functions as ready-made M&A currency that can be deployed at speed.
• Employee Share Schemes Treasury shares can be deployed to satisfy share grants and option exercises under Chapter 17 compliant share schemes. This gives companies a more flexible and capital-efficient mechanism for incentive plan funding compared to relying solely on new share issuance.
• Share Price Management and Signalling The original rationale for buybacks — signalling undervaluation, returning cash to shareholders, improving earnings per share — remains intact. The addition of treasury shares means that companies can now execute buybacks without foreclosing their options. If market conditions shift materially after a repurchase, they retain the ability to redeploy those shares rather than having permanently reduced their issued capital.

Board-level action checklist

For boards and company secretaries moving from awareness to execution, the following preparatory actions should be sequenced against the next annual general meeting cycle:

• Review constitutional documents for any restrictions on holding or using treasury shares. Amendments require shareholder approval and should be tabled at the AGM if not already addressed.
• Update general mandate resolutions to expressly authorise resales of treasury shares. Legacy wording that does not reference treasury shares will not permit resale under a general mandate.
• Update the explanatory statement for the share repurchase mandate to disclose whether the company intends to hold repurchased shares as treasury shares or cancel them (or retain discretion subject to market conditions).
• Embed the 30-day moratorium into the company's dealing policy and capital management calendar. The bidirectional restriction between repurchases and resales must be a standing governance control, not a one-time advisory note.
• Update dividend blackout procedures to ensure treasury shares are withdrawn from CCASS and re-registered or cancelled before the record date for any dividend or distribution.
• Brief the IR and investor relations teams on the Part XV SFO denominator implications for disclosure monitoring.
• Model stamp duty costs into any treasury share deployment scenario involving secondary market resales or consideration share structures.

The competitive context: Hong Kong catching up and moving ahead

The treasury share reform must be understood within a broader competitive narrative. Hong Kong has spent the past three years executing a series of capital market reforms — weighted voting rights, SPAC listings, the re-domiciliation regime, and now treasury shares — each designed to close competitiveness gaps with New York, London, Singapore, and offshore jurisdictions.

The Companies Registry has been explicit that the treasury share regime is expected to attract quality companies to incorporate their holding entities in Hong Kong, rather than defaulting to Cayman Islands or Bermuda structures. In the context of the re-domiciliation regime introduced in parallel — which allows overseas companies to migrate their place of incorporation to Hong Kong — the two reforms are complementary. A company that re-domiciles to Hong Kong no longer faces a capital management disadvantage relative to its Cayman-incorporated peers.

For decision-makers evaluating jurisdiction choices for new listing structures or considering re-domiciliation, Hong Kong's corporate law toolkit has become materially more competitive.
