Share Buyback in Hong Kong: How Companies Ordinance Cap. 622 Governs Off-Market Repurchases (2026)

What the Companies Ordinance says about share repurchases

Cap. 622 replaced the old Companies Ordinance in 2014 and consolidated the rules on share repurchases in Division 4 of Part 5. The Ordinance draws a hard line between two categories: market repurchases (shares bought through a recognised stock exchange) and off-market repurchases (everything else, including negotiated buybacks from identified shareholders or transactions through unlisted share platforms).

The off-market route is the more demanding of the two. Cap. 622 requires that any off-market repurchase be authorised by a special resolution — meaning at least 75 percent of votes cast at a general meeting where the selling shareholder, and any associate of that shareholder, is not entitled to vote on the resolution. That voting restriction is deliberate: it prevents the company from inflating the price at which a connected party exits.

The special resolution: what it must cover

The special resolution authorising an off-market repurchase is not a blank cheque. Under Cap. 622, the resolution must set out or have attached to it the proposed terms of the purchase contract, including price (or the formula for calculating it), the maximum number of shares that may be bought, and the time period within which the repurchase must be completed (as specified in the resolution and the purchase contract).

If the company later wishes to vary those terms, a fresh special resolution is required. A resolution that was passed for a different class of share does not carry over. Companies that want standing authority to conduct periodic buybacks therefore tend to revisit the approval at each annual general meeting — a practice that keeps the resolution current without the need for extraordinary general meetings throughout the year.

Shareholders can use a properly prepared shareholders' resolution to record and evidence the special resolution, ensuring the document captures the precise statutory requirements under Cap. 622 before the meeting is convened.

Directors' solvency statement

Before the repurchase can proceed, every director who voted in favour of authorising it must make a solvency statement. Cap. 622 sets out what that statement must confirm: that the company can pay its debts as they fall due at the time of the repurchase and for the 12 months immediately following. The statement must also confirm that the company's assets will exceed its liabilities — including contingent and prospective liabilities — throughout that period.

The solvency statement is made by each director personally. A director who makes a solvency statement without having reasonable grounds for doing so commits a criminal offence under Cap. 622, carrying a fine and possible imprisonment. The directors therefore need a genuine financial analysis — audited accounts, management accounts, or a cash flow forecast that a reasonable director would consider reliable — before signing.

The statement must be made within 15 days before the special resolution is passed, and it must be available for inspection by members at the meeting. A copy must also be sent to every member who is entitled to receive notice of the meeting, together with the notice itself.

What happens after the repurchase

Once the shares are repurchased, they are cancelled unless the company has elected to hold them as treasury shares. Treasury shares are permitted under Cap. 622 but are subject to their own restrictions: treasury shares carry no voting rights and receive no dividends. Most private companies in Hong Kong simply cancel repurchased shares, which reduces the issued capital accordingly.

A return must be filed with the Companies Registry within one month of the repurchase using Form NSC1 (Return of Purchase of Own Shares). The return records the number of shares repurchased, the price paid, and whether the shares were cancelled or converted to treasury shares. Late filing attracts a continuing default fine.

Stamp duty on off-market repurchases

Stamp duty applies to transfers of Hong Kong stock at a combined rate of 0.2 percent of the consideration (0.1 percent payable by each party). In an off-market repurchase, the company is the buyer, so the company pays its 0.1 percent — and the selling shareholder pays the other 0.1 percent — on the actual price paid for the shares. The instruments must be stamped within 30 days of execution. Unstamped instruments cannot be admitted as evidence in civil proceedings in Hong Kong.

Companies sometimes structure buybacks as a series of separate contracts rather than one large instrument, but that approach does not reduce the total stamp duty and adds administrative complexity without a proportionate benefit.

Listed companies: SFC disclosure obligations

Private companies deal only with Cap. 622 and the Companies Registry. Listed companies face an additional layer: the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the Listing Rules) and, where relevant, the Securities and Futures Ordinance (Cap. 571).

Under the Listing Rules, a listed company conducting an off-market buyback must obtain approval from independent shareholders at a general meeting. The company must also prepare a circular that explains the rationale, discloses the financial effect of the buyback, and includes a statement from independent financial advisers where required. For transactions above certain thresholds — or where the selling shareholder is a connected person — the reporting requirements under Chapter 14 or 14A of the Listing Rules apply in addition.

The SFC's Code on Share Buy-backs sets out conduct requirements for the period surrounding a repurchase: restrictions on buybacks when the company is in possession of inside information, blackout periods ahead of results announcements, and monthly disclosure to the Exchange of the aggregate number and price of shares bought back. A listed company's compliance team should map its planned buyback timeline against these windows before the board authorises anything.

Key procedural checklist for off-market buybacks

Directors authorising an off-market repurchase should work through a short but non-negotiable sequence:

First, confirm the company's articles of association permit share repurchases and do not impose additional restrictions beyond Cap. 622. Many older articles were drafted before 2014 and may reference provisions of the previous Ordinance; those references need to be read carefully in context.

Second, obtain a financial analysis supporting the solvency statement. The 15-day window between the statement and the resolution is tight — commissioning management accounts or a cash flow model should happen well before the meeting notice goes out.

Third, prepare the resolution in a form that meets Cap. 622's requirements (terms of the purchase contract attached or set out, price, maximum shares, time limit). Circulate it with the solvency statement and the meeting notice simultaneously.

Fourth, hold the meeting. The selling shareholder and associates cannot vote. Record the vote count carefully — 75 percent of votes cast, not of total shares in issue.

Fifth, execute the purchase contract, stamp it within 30 days, and file Form NSC1 with the Companies Registry within one month of completion.

Common reasons repurchases fail

Repurchases most often run into trouble at two points. The solvency statement is the first: directors underestimate how specific the financial basis needs to be, or they rely on outdated accounts when the company's liquidity position has deteriorated. Cap. 622 creates personal criminal liability for a director who makes a solvency statement without reasonable grounds, which concentrates the mind — but the solution is proper financial due diligence, not a cursory review of the last set of annual accounts.

The voting restriction at the general meeting is the second. Identifying who counts as an "associate" of the selling shareholder for the purpose of the exclusion from voting requires care; Cap. 622 defines the scope of associated parties to cover spouses, dependent children, and entities controlled by or closely connected to the selling shareholder. A missed associate who votes on the resolution can invalidate the entire approval.

Off-market buybacks in Hong Kong are a legitimate and well-used tool for returning capital to selected shareholders, facilitating management buyouts, or adjusting the ownership structure ahead of a refinancing. Cap. 622's procedural requirements are not obstacles — they are the architecture that makes the transaction legally secure for all parties.
