Applying for an IPO doesn't mean you'll get shares. In highly popular ones, many investors wonder the reasons for non allotment of ipo shares. Knowing how the allocation process works and understanding rejections can help investors manage expectations and maybe do better next time. This piece covers why applications fail to get shares, what follows an unsuccessful try, and ways to boost your chances of getting allotted IPO shares.

Overview of IPO Allotment 

IPO allotment happens when shares are handed out to folks who apply during the initial public offering. After the IPO application window closes, the registrar figures out who gets the shares. 

Several things affect the allotment process, like how many shares there are, the type of investor, and how much those shares are wanted. Sometimes, if too many people want the shares, not everyone gets some. This is one of the most common reasons for non allotment of IPO shares, especially in popular IPOs that attract strong investor interest. To better understand the allocation process, investors can learn more about the IPO allotment process and how shares are distributed among applicants.

How IPO Allotment Process Works? 

After allotment, investors should also understand what IPO lock-up means, as lock-up periods can influence the availability of shares in the market after listing. Once an IPO closes, the registrar checks all applications and makes sure the investor info is correct. They then consider eligible applications using regulatory guidelines and the subscription levels. 

The general steps for allotment include: 

  • The IPO stops accepting subscriptions. 
  • The registrar checks all applications. 
  • They toss out invalid or incomplete ones. 
  • Next, shares get allotted based on investor type and demand. 
  • Unsuccessful applicants get their money refunded. 
  • Successful investors have their shares added to their Demat accounts. 

When an IPO is oversubscribed, there might be a lottery for the retail category, meaning even with a proper application, you still might not get allotted any shares. 

Top Reasons for Non Allotment of IPO Shares 

There are some reasons for non allotment of ipo shares: 

  • IPO Oversubscription 
    Not receiving shares may be due to an oversubscription to an IPO offer. If there are more applications than shares, then there is a good chance that not everyone will receive shares. 
  • Lottery Share Allocations 
    These provide an opportunity for a share allocation, but in these instances, a valid application may not guarantee an allocation. 
  • Application Detail Error 
    An application may be rejected for an error in a PAN number, an error in a Demat account, or an error in a personal detail. 
  • Application Rejections 
    In the same application category, multiple applications using the same PAN will guarantee a rejected application. 
  • Funds Blocked and Other Payment Issues 
    An application may be rejected if a payment-related (i.e. insufficient balance in a bank or payment-related error) application is made. 

Other Possible Reasons for IPO Non-Allotment 

There are many reasons for non allotment of ipo shares besides oversubscription. 

  • PAN and Demat information inconsistencies 
  • Demat account is invalid or not operational 
  • Select the wrong category 
  • Incomplete application 
  • System issues 
  • Did not meet criteria 

To avoid these consequences, investors are encouraged to conduct a thorough review of all application details prior to completing the IPO application. 

What Happens If IPO Is Not Allotted? 

Investors who do not receive an allotment can track the refund and application status through the IPO allotment status page for the latest updates. If an investor does not obtain shares in an initial public offering (IPO), the Application Supported by Blocked Amount (ASBA) process stipulates that the blocked amount is either released or refunded. 

Normally, the investor is not required to do anything further. After the allotment process is complete, the funds will be available in the investor's bank account. 

Investors may participate in other IPOs to refine their applications. The experience may help develop an understanding to recognize the reasons for not being allotted shares in an IPO. This understanding will help reduce avoidable errors in future applications. 

How to Increase IPO Allotment Chances?

Though IPO allotment isn't guaranteed, you can boost your chances with some smart moves. 

First, apply as a retail investor if you qualify. Next, make sure your application info is spot on. Also, keep enough cash in your bank account. Don't submit duplicates either. Another tip is to apply using different family members with their own PAN numbers. Finally, aim for IPOs that aren't totally oversubscribed. 

These tips might help you sidestep mistakes and up your odds of getting shares. Knowing why past applications weren't successful also lets you apply smarter next time and improves your overall IPO experience.
