Synopsis
Tonbo Imaging India’s IPO opens October 15, 2026, aiming to raise Rs 852.18 crore through an offer for sale. With a 71% grey market premium, listing gains are anticipated. However, FY26 total income fell 22% and profit declined 30%. The defence technology company operates across 24 countries, specialising in advanced imaging and surveillance systems.
Tonbo Imaging India’s IPO opens for subscription on Thursday, with the issue commanding a grey market premium (GMP) of 71%. The premium points to strong listing gain expectations in the unofficial grey market, although actual listing performance may differ.
The Bengaluru-based defence technology company is looking 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 funds raised will go to the selling shareholders.
Tonbo Imaging India has fixed the price band at Rs 665–700 per share. The IPO will open on October 15 and 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.
The lot size has been set at 21 shares, requiring a minimum investment of Rs 14,700 for retail investors applying at the upper end of the price band. The face value of each equity share is Rs 2.
Ahead of the public issue, Tonbo Imaging India raised Rs 255 crore from anchor investors. The company allotted 36.48 lakh equity shares at Rs 700 apiece, the upper end of the IPO price band.
Live Events
JM Financial and IIFL Capital Services are the book-running lead managers for the issue, while KFin Technologies has been appointed as the registrar.
