Most IPO lockups release on a date. A smaller number release on a date and a price — the stock has to trade above a specified threshold for a set number of sessions before insiders are freed. It is a clause worth understanding, because it inverts the usual assumption about what an unlock means, and because it creates a feedback loop that a plain calendar lockup does not.

Short answer: a lockup with a price condition attached
Short answer: A price-contingent lockup (sometimes called a price-based or early-release lockup) allows insiders to sell before the standard expiry, but only if the share price clears a defined level — commonly a percentage above the IPO price — and holds it for a specified run of trading days. If the condition is never met, the shares stay restricted until the ordinary date. The effect is that strength triggers supply and weakness does not.
The mechanic: hitting a threshold, not just a date
A typical clause has four moving parts, all of which are spelled out in the underwriting agreement and summarised in the prospectus.
- The threshold. A price level, usually expressed as a multiple or percentage of the IPO price — 120% and 133% are common formulations.
- The duration test. The stock must close above the threshold for a minimum number of sessions within a defined window, often something like 10 of 15 consecutive trading days. A single intraday spike does not qualify.
- The earliest eligible date. Even if the price test is satisfied, release cannot occur before a stated day — frequently tied to the second trading day after the first post-IPO earnings report, so that insiders are not selling into an information vacuum.
- The released proportion. Early release is usually partial. A defined percentage of each holder’s stake unlocks, not the whole position.
Miss any one of those and the clause simply does not fire. The shares remain locked to the original schedule.
A worked example
Take a company that priced its IPO at $100. The lockup runs 180 days, with an early-release clause at 133% of the offer price — $133 — requiring 10 closes above that level within any 15-day window, no earlier than two days after the first earnings report.
If the stock runs to $150 in month three and holds there, the clause fires at the earliest eligible date and a defined slice of insider stock becomes sellable months early. If the stock spends month three at $120, nothing happens; the same shares stay locked, and the market now knows the threshold was tested and missed. If the stock trades at $90, the clause is irrelevant and the only date that matters is the original expiry.
Note what the second scenario does. The threshold becomes a publicly known price level with a supply consequence attached — which is a different thing from an ordinary resistance level.
Why underwriters started writing these clauses
The motivation is straightforward: a single-date lockup concentrates all insider supply into one session and creates a well-telegraphed overhang that short sellers can position around for months. Underwriters and issuers have an interest in dispersing that.
A price-contingent clause disperses it in a particular way — it releases stock only into demonstrated strength. From the issuer’s perspective, that is supply arriving when the market has the appetite to absorb it. From the employee’s perspective, it is an earlier path to liquidity in exchange for accepting that liquidity is conditional. Both sides get something, which is why the structure has spread beyond the handful of high-profile listings that popularised it.
The reflexivity problem: unlocking on strength, staying locked on weakness
This is the part that distinguishes a price-contingent lockup from a calendar one, and it cuts both ways.
On the upside, a rally toward the threshold is self-limiting in a mild sense. Market participants can see the level, know what clearing it releases, and may anticipate the supply — which can cap the move before the test completes. The clause effectively writes a known supply event into the chart at a specific price.
On the downside, a stock trading well below its threshold has less insider supply than an equivalent company with a plain lockup. Weakness protects the price from the very selling that weakness would otherwise invite. That is a genuinely unusual property, and it means the standard reasoning — “the stock is down, insiders will want out” — runs backwards here.
Neither effect is large enough to build a strategy on. Both are large enough to misread a chart if you do not know the clause exists.
Where you find the terms — S-1, prospectus, lockup agreement
These clauses are disclosed, but not prominently. The places to look, in order of usefulness:
- The Form S-1 or S-1/A, “Shares Eligible for Future Sale” section. This is the canonical summary — it states the lockup length, any early-release conditions, and the approximate share counts becoming eligible at each stage.
- The “Underwriting” section of the same filing. Contains the lockup agreement terms and any underwriter discretion to waive them.
- The final prospectus (424B4). The priced version, with the actual IPO price filled in — which is what the percentage thresholds are calculated against.
- Subsequent 10-Q and 10-K filings. Companies frequently restate the remaining schedule, which is the easiest way to check what is still restricted.
One thing worth checking specifically: underwriters commonly retain the right to release shares from the lockup at their discretion, regardless of any price condition. A waiver can happen at any time and is not always announced with fanfare.
Risks, uncertainty, and limits
The terms described here are typical rather than universal. Thresholds, duration tests, eligible dates and released proportions vary considerably between deals, and there is no standard form — two companies listing the same month can have materially different clauses.
There is also very little empirical research on price-contingent lockups specifically, because the structure is recent and the sample is small. The literature on conventional lockup expiries — a modest, largely pre-priced negative drift — cannot be assumed to transfer to a clause whose entire mechanism is conditional on prior strength. Anyone quoting a historical average effect for these is extrapolating from a different instrument.
For any specific company, the filing is the only authoritative source. Read the “Shares Eligible for Future Sale” section rather than a summary of it.
