Financing Locked-Up Shares: IPO Lock-Ups, Cornerstones & Controlling-Shareholder Restrictions

Part of the Hong Kong Stock Loan Regulatory & Eligibility Guide — view the full guide →

Collateral is only useful to a lender if it can be sold. That single premise governs how a stock loan is priced, sized, and structured — and it is precisely the premise that a lock-up disturbs. A locked-up share is one the holder has bound itself not to dispose of for a defined period, whether by the HKEX Listing Rules, by an undertaking given at IPO, or by private contract. For the duration of that period the share behaves, for financing purposes, like an asset with the exit door temporarily sealed.

This does not mean a locked-up position cannot be financed. It means the lock-up is the first thing a lender reads, that it ties eligibility to a real and datable liquidity trigger — the expiry — and that the structure is built around that date rather than in spite of it. What follows is the framework, not a promise: as always on this site, there is no published rate and no LTV grid, and the exact terms of any lock-up are a matter for the holder’s own Hong Kong counsel.

The four lock-ups that matter

"Lock-up" is a single word for several distinct restrictions, and they do not all behave the same way. The post-IPO controlling-shareholder lock-up is imposed by the HKEX Listing Rules on the controlling shareholder of a newly-listed issuer, and applies as a matter of rule rather than negotiation. The cornerstone-investor lock-up is the undertaking a cornerstone gives, in exchange for a guaranteed allocation at IPO, not to sell for a stated period. The GEM lock-up is the equivalent regime for issuers on the Growth Enterprise Market, historically framed on its own terms. And the contractual lock-up is any private restriction — a placing agreement, an orderly-market undertaking to an underwriter, a shareholders’ agreement — that binds the holder outside the Listing Rules entirely.

The distinction matters because the source of a lock-up determines who can waive it, how it is disclosed, and when it ends. A rule-based lock-up runs to a date fixed by the framework; a contractual one runs to whatever the parties wrote, and may or may not permit an encumbrance short of a disposal.

The general HKEX position

As a general matter, the HKEX Listing Rules subject a controlling shareholder to a lock-up following a Main Board listing: an initial period during which it may not dispose of any of the relevant shares, followed by a further period during which it may not dispose of shares to the extent that it would cease to be a controlling shareholder. The Growth Enterprise Market has its own, historically longer, formulation. These are the general contours; the precise duration, the shares caught, and the carve-outs that may apply to a given holder are questions for that holder’s Hong Kong legal counsel, not matters to be assumed from a summary. Cornerstone lock-ups, by contrast, are creatures of the placing documents and are not uniform from deal to deal.

Why locked-up shares resist being collateral

A lender secured against shares relies, in the last resort, on the ability to realise them. A lock-up removes that ability for its duration. Even where the restriction bites on disposal and a pledge is not itself a disposal, the lender must ask what enforcement would look like: a security interest that could only be realised after expiry, or one whose enforcement might itself breach the holder’s undertaking, is worth far less than clean, unencumbered stock. The eligibility screen set out in our note on which HKEX stocks can be pledged applies here with an extra layer: liquidity, free float, and traded value all still matter, but they are read behind the lock-up, not instead of it. A locked-up position in a Chapter 18A or 18C name — where our note on pre-profit listings already counsels caution — compounds both effects.

Timing to, and structuring around, expiry

Because a lock-up has a known end date, it is a liquidity trigger a lender can plan around rather than a permanent bar. Two broad approaches recur. The first is to time the facility to expiry: a forward-starting arrangement, agreed and documented before the lock-up ends, under which the collateral becomes freely realisable — and the facility properly secured — only once the restriction falls away. The second is to structure conservatively across the window, sizing the advance to reflect that, for part of the tenor, the collateral is encumbered by the undertaking. Which is appropriate depends on the source of the lock-up, its remaining term, and whether it restricts encumbrance as well as sale. None of this changes the fundamentals set out on our stock loans page; it applies them to a position with a clock on it.

The disclosure overlay

A holder locked up as a controlling shareholder or cornerstone is, almost by definition, a substantial shareholder, a director, or both — which brings the SFO Part XV Disclosure of Interests regime into play alongside the lock-up itself. Granting security over a large stake can be a notifiable event, and the director/chief-executive limb of the regime carries no 5% floor. Our note on SFO Part XV disclosure sets out that machinery; the point here is that a lock-up and a disclosure obligation frequently travel together, and both are settled at the outset with the holder’s own counsel, in parallel with the financing structure rather than after it.

A lock-up does not make a share un-financeable — it puts a date on when it becomes financeable, and the structure is built to that date. Read early, the expiry is an input; read late, it is an obstacle.

All references to lock-up periods, eligibility, loan-to-value, and tenor are general and illustrative only; no fixed rate or LTV grid is published, and any indicative terms are issued only after review of a specific position. The precise duration, scope, and carve-outs of any lock-up — whether imposed by the HKEX Listing Rules (including the controlling-shareholder, GEM, and cornerstone regimes), by an IPO undertaking, or by private contract — and whether the SFO Part XV Disclosure of Interests regime or the SFC Codes on Takeovers and Mergers apply to any pledge, are questions for your own Hong Kong legal counsel, engaged in parallel with structuring. Hong Kong Stock Loans acts as an arranger and introducer in collaboration with SFC-licensed counterparties.
