Defence electronics manufacturer Tonbo Imaging India has established a price band of ₹665 to ₹700 per equity share for its upcoming initial public offering, aiming to raise ₹852.1 crore through an entirely secondary share sale. Public bidding for the issue is scheduled to commence on October 15 and close on October 19, following a dedicated session for anchor investors on October 14.
At the upper limit of the pricing bracket, the valuation of the technology firm stands at approximately ₹4,009.8 crore, or roughly $480 million. The company refiled its draft papers in August, and market regulators issued observations on the draft red herring prospectus last month.
The public offering consists exclusively of an Offer for Sale of up to 1.22 crore equity shares by current promoters and institutional backers. Because the transaction involves no fresh issue component, the enterprise itself will not secure any financial proceeds from the share placement, with the entirety of the transaction value flowing directly to the exiting stakeholders.
The roster of selling participants includes cofounders and promoters Arvind Kondangi Lakshmikumar, Ankit Kumar, and Cecilia D'Souza. The offering scale was trimmed from the 1.81 crore shares initially outlined in preliminary filings.
Established in 2003 by former researchers associated with the US Department of Defense and Sarnoff Corporation, Tonbo transitioned from research and development services toward proprietary defence manufacturing after a management buyout by its current promoters in 2012. The organization currently designs advanced electro-optic, sensing, processing, and targeting systems utilized in military, surveillance, and law enforcement operations across international markets.
The operational framework follows an asset-light manufacturing strategy, relying on certified third-party electronics manufacturing service providers such as Kaynes Technology and Avalon Technology for volume production while keeping prototype engineering, system integration, and qualification testing in-house. By June 30, the firm had deployed more than 28,000 systems across 24 countries, spanning thermal imaging cores, weapon sights, handheld binoculars, driver-vision systems, fire-control apparatus, and missile seekers alongside emerging platforms like loitering munitions and anti-drone microwave solutions.
Financial statements indicate softening revenue figures leading up to the public offering. For the first quarter of fiscal year 2027, the enterprise posted operating revenue of ₹36 crore alongside a net loss of ₹17.7 crore. For the full fiscal year ended March 2026, revenue from operations contracted by 22.7% to ₹362.6 crore compared with ₹469.1 crore in the preceding financial year, while annual net profit declined 43% year-on-year to ₹50.8 crore from ₹72.8 crore.
Book-running lead management responsibilities for the offering are shared by JM Financial and IIFL Capital Services, while KFin Technologies acts as the official registrar. The equity shares are slated for official admission and trading on both the BSE and the National Stock Exchange on October 23.
An initial public offering's upper price band does not show whether its valuation is reasonable on its own. Prospective investors need the company's revenue mix, profitability, cash flow, customer concentration and use of proceeds, ideally reconciled to the offer document. Defence and imaging businesses may depend on procurement approvals, long delivery schedules and a few large customers; these risks can be more important than a recent growth rate. Readers should distinguish fresh issuance from an offer for sale, since only fresh-issue proceeds reach the company. Market commentary should avoid treating an expected listing premium as assured income, particularly before the offer closes or allotment is determined.
