The Indian IPO market has witnessed record listings over the past few years. Now, the next important phase for many of these IPOs is about to begin as the lock-in period for early investors, promoters, and anchor investors comes to an end. Over the next three months, shares worth more than Rs 3 lakh crore from approximately 73 companies may become available for trading. This could increase the supply of shares in the market and potentially impact stock prices as well as investor strategies.
Let us understand what IPO lock-in expiry means, which major companies are affected in the coming months, and what impact it could have on investors.
What’s Happening?
After an IPO, certain categories of investors are restricted from selling their shares for a specified period, known as the lock-in period. The objective is to prevent large-scale selling immediately after listing, which could create excessive volatility in the stock.
Now, between the end of May and August 2026, the lock-in period is set to expire for a large number of companies. According to Nuvama Institutional Equities, shares worth approximately Rs 3.29 lakh crore ($34 billion) from around 73 companies may become eligible for trading. These include one-month, three-month, and six-month lock-in expiries.
However, the end of the lock-in period does not necessarily mean that all investors will immediately sell their holdings. Even so, such a large potential increase in share supply can become an important factor for the market and may lead to short-term volatility in select stocks.
Major Upcoming Lock-in Expiry Events
Several one-month, three-month, and six-month lock-in periods are ending, making shares of multiple companies available for trading. In some cases, the unlocked stake is relatively small, while in several large companies, 50% to 70% of equity may become eligible for trading.
In the one-month category, only OnEMI Technology Solutions’ lock-in period will end, while the three-month category includes companies such as SEDEMAC Mechatronics, Central Mine Planning, Sai Parenterals, Powerica, and Om Power Transmission. In these cases, a relatively small portion of equity is being unlocked.
However, the biggest impact is likely to come from the six-month lock-in expiries. Large quantities of shares from companies such as Meesho, ICICI Pru AMC, Corona Remedies, and Bharat Coking Coal will become eligible for trading. Such significant unlock events can increase share supply in the market, potentially leading to short-term volatility and profit-booking pressure in these stocks.
Potential Impact of Lock-in Expiry on the Market
The end of a lock-in period does not mean that all investors will immediately sell their shares. However, when a large quantity of shares is expected to become available for trading, the market often begins pricing in the possibility of increased supply beforehand. As a result, stocks may come under pressure around the time of lock-in expiry.
Recent examples show that shares such as Pine Labs, PhysicsWallah, Lenskart, and Waaree Energies declined by 3% to 11% after lock-in expiry, as early investors got an opportunity to book profits.
That said, the impact is not the same across all companies. Businesses with weak post-listing performance or where investors are sitting on limited gains may witness higher selling pressure. On the other hand, companies with strong business models, healthy financial performance, and attractive growth prospects often stabilise quickly after the initial selling pressure. Therefore, lock-in expiry should not be viewed solely as a risk but also as an important indicator of market supply and investor behaviour.
What Does This Mean for Investors?
For retail investors, it is important to understand that lock-in expiry is neither a buy signal nor a reason to sell by itself. It is simply an event that increases the number of shares available for trading.
Investors should pay particular attention to companies where a large percentage of equity is being unlocked and where the stock is already facing pressure. In such situations, short-term price fluctuations may increase.
On the other hand, if a company has strong fundamentals, consistent revenue growth, and reasonable valuations, any weakness caused by lock-in expiry could create opportunities for long-term investors. Therefore, it is more important to focus on the company’s underlying business strength rather than the event itself.
What’s Next?
The Indian IPO market continues to expand, and lock-in expiry events are likely to become increasingly common in the years ahead. As more companies get listed, the market will regularly witness large share unlock events.
For investors, participating in IPOs alone will not be enough. It will also be important to monitor post-listing developments such as lock-in expiries, changes in promoter holdings, and institutional investor activity.
Overall, the $34 billion worth of shares becoming eligible for trading over the next three months could create temporary volatility in the market. However, over the long term, a company’s performance will be determined by its business fundamentals, profitability, and growth prospects, not merely by the expiry of a lock-in period.
