Share Option Agreements Under the Hong Kong Companies Ordinance (2026): 7 Things Directors Get Wrong

1. Missing the register of option holders under Cap.622

The Companies Ordinance (Cap. 622) requires every company that grants options over unissued shares to maintain a register of option holders. The register must record the grantee's name and address, the date the option was granted, the number of shares over which the option is granted, the exercise price, and the period during which the option may be exercised.

Directors routinely treat this as an administrative afterthought. The consequence is not merely a compliance gap — failure to maintain the register is a statutory offence, and any officer in default is personally liable. Courts look at the register when disputes arise about whether options were actually granted, so an incomplete register can undermine the company's own position in litigation.

The register must be kept at the company's registered office or at another place notified to the Registrar of Companies. If it is kept elsewhere, the company must file the prescribed notification form with the Companies Registry — confirm the current form reference with the Registry before filing.

2. Confusing vesting with exercise — and pricing both wrong

A share option has two distinct events: vesting (the grantee earns the right to exercise) and exercise (the grantee actually buys shares at the agreed price). Directors sometimes treat these as synonymous, which causes cascading errors in the agreement itself, in accounting treatment, and in stamp duty analysis.

Vesting schedules are creatures of contract. Nothing in Cap.622 prescribes how vesting must work. The parties can agree cliff vesting, monthly pro-rata vesting, milestone-based vesting, or any hybrid. What the agreement must make unambiguous is what happens on departure before full vesting — so-called "good leaver / bad leaver" provisions. Vague language here is the single most litigated aspect of Hong Kong option schemes.

Exercise is a separate act with its own formalities. The grantee must give notice of exercise in the form specified in the agreement, and the company must then allot shares in accordance with Cap.622 Part VIII. An allotment made without a valid exercise notice is voidable.

3. Ignoring SFC Part XV disclosure for listed-company options

For companies listed on the Hong Kong Stock Exchange, Part XV of the Securities and Futures Ordinance (Cap.571) creates a parallel disclosure regime that sits entirely outside the Companies Ordinance. Directors and substantial shareholders must disclose interests in shares — and options over shares count as interests.

Under Part XV of Cap.571, a director who is granted options over listed shares must notify the company within three business days of the grant. The company must then file a disclosure return with HKEx under the governing provision of Part XV of Cap.571 dealing with the listed corporation's notification obligation. Unlike the substantial shareholder regime (which has a 5% voting-rights threshold), directors and chief executives must disclose all interests regardless of size — there is no minimum percentage floor for directors' disclosures. The disclosure obligation applies to the specific class of shares over which the option is granted.

For unlisted companies, Part XV does not apply, but directors should check their articles and any shareholders' agreement for equivalent private-company disclosure obligations, which are common in institutional-investor deals.

4. Getting stamp duty wrong at grant — then again at exercise

Stamp duty is where the most expensive mistakes happen. The Stamp Duty Ordinance (Cap.117) treats grant and exercise differently, and the two events attract duty at different times.

At grant: a share option agreement is a "contract note" for stamp duty purposes only if it relates to Hong Kong stock. For options over unissued shares of a Hong Kong-incorporated company, the position has historically been that the grant itself is not stampable because no stock changes hands. However, if the option agreement is combined with a transfer — for example, in a secondary transaction where an existing shareholder grants options over existing shares — stamp duty at 0.1% on each side (total 0.2% of the consideration or value, whichever is higher) applies on execution.

At exercise: when the grantee exercises and new shares are allotted, there is no stamp duty on allotment of new shares (stamp duty applies to transfers, not allotments). But if exercise involves a transfer of existing shares — as occurs in secondary schemes — stamp duty applies at the prevailing rate under the First Schedule to Cap.117, charged on the higher of consideration and market value.

Directors who assume "stamp duty applies once, at exercise" without distinguishing the transaction structure are setting up a tax exposure that the Inland Revenue Department will eventually surface.

5. Omitting personal data obligations under the PDPO

The Personal Data (Privacy) Ordinance (Cap.486) applies to any personal data collected in connection with an option scheme. The agreement and supporting documentation will typically collect grantees' names, identity card numbers, addresses, bank details, and employment information — all personal data under the PDPO.

The company as data controller must, at or before collection, give a Personal Information Collection Statement (PICS) under Data Protection Principle 1(3). The PICS must state the purpose of collection, the classes of persons to whom data may be transferred, and the grantee's right to request access and correction.

Data must not be retained longer than necessary for the purpose for which it was collected. In practice, a company should decide at the outset how long it will retain option-scheme records after a scheme terminates — typically the limitation period for any contract claims (six years under the Limitation Ordinance Cap.347) is the sensible minimum.

Failure to issue a PICS is not merely a technicality: the Office of the Privacy Commissioner for Personal Data can investigate and issue enforcement notices, and grantees who suffer damage from a breach may claim compensation under s.66 PDPO.

6. Treating the option agreement as the whole scheme

Directors of smaller companies frequently document an option grant with a single agreement between company and grantee and treat the matter as closed. For a one-off grant to a single senior hire, this may be adequate. For any scheme involving multiple grantees, the single-agreement approach creates inconsistency over time: different grantees end up with materially different terms because each agreement is negotiated separately, vesting schedules drift, and good-leaver provisions evolve document by document.

A properly constituted scheme has three layers: the scheme rules (the master document governing all grants), individual grant letters (incorporating the rules and specifying grantee-specific terms), and board resolutions approving each grant. The scheme rules should be approved by shareholders if shares represent more than 10% of the issued share capital — not a statutory requirement for private companies in all cases, but standard practice that protects directors from later allegations of self-dealing under their fiduciary duty to avoid conflicts of interest, which applies to Hong Kong directors as a matter of common law.

7. Failing to consider tax treatment for the grantee — and its effect on scheme design

Hong Kong does not have capital gains tax, which makes it more attractive than many jurisdictions for option schemes. However, the Inland Revenue Ordinance (Cap.112) taxes employment income, and options granted to employees are treated as employment income when exercised, not when granted. The assessable amount is the market value of the shares at the time of exercise less the exercise price paid.

Directors sometimes design schemes without consulting the grantee on this point. An employee who exercises options when the share price has risen significantly may face a salaries tax liability in the year of exercise — even if the shares are illiquid and cannot immediately be sold to fund the tax bill. This is particularly acute for employees of unlisted companies, where there is no ready market for the shares.

The solution is not to avoid options — the tax treatment is still generally favourable compared with most other jurisdictions — but to structure the exercise windows and vesting timelines with the grantee's liquidity position in mind, and to make the tax consequences explicit in the grant documentation.

Practical checklist before executing any grant

Before any Hong Kong company executes a share option agreement, directors should confirm: the statutory register of option holders is in place and will be updated on signing; the exercise price is set at or above the agreed basis (market value, par value, or a board-determined price, depending on scheme rules); if the company is listed, Part XV notification timelines are in the board's calendar; stamp duty analysis has been obtained from a solicitor or tax adviser for the specific transaction structure; a PICS has been prepared for the grantee; and the agreement cross-references scheme rules if other grantees exist.

Getting these seven points wrong costs real money — in stamp duty, IRD penalties, and regulatory censure. Getting them right is mostly a matter of preparation before the agreement is signed, not remediation afterwards.
