Tonbo Imaging India IPO entered its final day of bidding on Monday, amid strong investor demand. The IPO’s grey market premium (GMP) rose to 74% from 71% earlier, indicating higher listing gain expectations in the unofficial market. However, the grey market premium is an unofficial indicator and does not guarantee listing performance.
The IPO was subscribed 7.78 times by the end of Day 2, against 85.26 lakh shares on offer. The retail individual investor (RII) category saw 7.13 times subscription, against 42.56 lakh shares reserved for the segment.
The Bengaluru-based defence technology company aims to raise Rs 852.18 crore through the public issue. The IPO is entirely an offer for sale (OFS) of 1.22 crore shares, meaning the company will not receive any proceeds from the issue. Instead, the proceeds will go to the existing shareholders selling their stakes.
Tonbo Imaging India has set the IPO price band at Rs 665–700 per share. The issue opened for subscription on October 15 and will close on October 19, 2026.
The basis of allotment is expected to be finalised on October 21, while the shares are tentatively scheduled to list on the BSE and NSE on October 23.
