Lock-up Expiration Calendar
Check in advance how many shares could hit the market when mandatory holding periods end.
Why lock-up expirations matter
Share supply hits the market
When shares held by institutions and major shareholders come off their mandatory holding period and reach the market, they can create short-term supply pressure.
Check the ratio
The larger the unlocked share relative to total shares outstanding, the bigger the potential impact.
1, 3 and 6 months after listing
For IPO shares, lock-up expirations often cluster at 1 month, 3 months and 6 months after listing.
