An IPO lock-up period is a fixed time after a company’s IPO listing during which certain categories of shareholders are not allowed to sell their shares. This category of shareholders includes promoters, anchor investors, employees, etc. The key purpose of the lock-up period is to stop heavy selling just after the listing of the IPO.

- Stable Stock Price: The key objective of the IPO Lock-Up period is to provide stability in stock prices after the listing on the stock exchange.
- Increases Confidence: The IPO Lock-Up period increases confidence among the retail investors, as promoters, etc., cannot sell their shares.
How Does an IPO Lock-Up Period Work?
The steps of an IPO Lock-Up period works is as follows:
- IPO Issue: Whenever the company issues its IPO, it mentions the lock-in rule in its offer document based on the guidelines provided by SEBI.
- Allotment and Listing: Once the IPO issue process is completed, the shares are allotted to the respective shareholders. And after the allotment, stocks get listed on the stock exchange.
- Restriction on Sale: There are certain categories of investors, such as promoters, anchor investors, etc., who are restricted from selling their shares for a specific period of time.
- Expiration of Lock-Up Period: Once the lock-up period expires, those investors become free to sell their shares in the open market. The availability of a large number of shares can create volatility in share prices.
IPO Lock-Up Rules for Different Investors
Different types of investors have different Lock-Up rules in IPO. The rules related to Lock-Up rules are as follows:
- Promoter Lock-Up Rule: According to the regulations issued by the Securities and Exchange Board of India, promoters’ shares are generally locked in for a period of 18 months from the allotment date of shares. However, in certain cases where IPO proceeds are heavily used for capital expenditure, the lock-in can extend to 3 years. Additionally, any promoter shareholding above the minimum promoter contribution of 20% is generally subject to a lock-in period of 6 months from the date of allotment, as per SEBI regulations.
- Anchor Investors Lock-Up Rule: The anchor investors have different lock-in periods. The first 50% of the shares are locked in for a period of 30 days. Whereas, the remaining 50% of the shares can be sold after a period of 90 days.
- Institutional Investor: The key institutional investor, including venture capital firms, private equity investors, etc., who purchase shares before the IPO period, faces a lock-up based on the regulations laid down by the SEBI. Under current SEBI regulations, many non-promoter pre-IPO investors typically face a 6-month lock-in period from allotment.
- Employee Lock-Up: There are various companies that issue shares to their employees in the form of Employee Stock Ownership Plans. Such shares also have restrictions on selling shares after the listing of the IPO.
Advantages of IPO Lock-Up Period
The key advantages of the IPO Lock-Up period are as follows:
- Stability in Stock Price: The Lock-Up period restricts large shareholders from selling their shares immediately after listing on the stock exchange. It reduces the chance of a sudden crash in the price of shares.
- Reduces Manipulation Risk: In case the lock-up period does not apply to insiders or large shareholders, they might sell large quantities of shares once the shares are listed on the stock exchange. This reduces the chance of any manipulation in stock prices.
- Increase Confidence of Investors: Due to the lock-in period, the retail investor feels more confident before investing in any IPO. It indicates that the large investors believe in the company’s future growth.
