Tonbo Imaging Plans Dalal Street Debut with 1.81 Crore Share Pure Offer for Sale

Defence electronics original equipment manufacturer (OEM) Tonbo Imaging India Limited is set to open its initial public offering (IPO) on domestic bourses next week. The issue is structured strictly as an offer for sale (OFS) of up to 1,80,85,246 equity shares with a face value of ₹2 each, with no fresh equity capital being issued by the company.

The secondary share sale will see offloading by promoter selling shareholders Arvind Kondangi Lakshmikumar, Ankit Kumar, and Cecilia D'Souza, alongside promoter group entities and early financial backers. Investors participating in the transaction include marquee private equity and venture firms such as Artiman, Celesta Capital, Qualcomm Ventures, Edelweiss Value and Growth Fund, Tenacity Ventures, India Exim Bank, and Florintree.

Because the offering is an entirely secondary divestment, all net proceeds will go directly to the selling shareholders, and Tonbo Imaging will receive no capital injection to pare down borrowings or fund business operations.

IPO Structure and Share Allocation

The issue allocation follows statutory guidelines across investor categories:

• Up to 50% of the net offer is allocated to Qualified Institutional Buyers (QIBs).
• A minimum of 15% is reserved for Non-Institutional Investors (NIIs / High Net-Worth Individuals).
• A minimum of 35% is allocated to Retail Individual Investors (RIIs).

JM Financial Limited and IIFL Capital Services Limited have been appointed as book-running lead managers to the issue, while KFin Technologies serves as the registrar. The company's equity shares will be listed on both the BSE and the National Stock Exchange of India (NSE).

Business Model and Defence Footprint

Founded in 2003 and transitioned toward dedicated defence optronics manufacturing in 2012, Tonbo Imaging manufactures advanced imaging, electro-optical, targeting, and missile-guidance solutions. Its hardware catalog includes thermal imaging cores, weapon sights, day-and-night vision binoculars, fire-control modules, and seeker technologies used across global militaries and domestic armed forces. As of March 31, 2026, the company had deployed more than 28,000 systems across 24 countries.

According to a Frost & Sullivan report cited in the draft prospectus, Tonbo Imaging was the largest manufacturer by sales value of thermal imaging systems supplied to government and defence agencies in India between FY24 and FY26, accounting for over 93% to 94% of India's total thermal imaging exports by unit volume during that span.

The company relies on an asset-light operating model. While retaining 100% in-house ownership of its intellectual property—including optics design, firmware, and edge electronics—Tonbo outsources volume component fabrication to certified domestic electronics manufacturing services (EMS) providers such as Kaynes Technology India and Avalon Technologies. Final assembly, system integration, software calibration, and military-grade qualification testing remain in-house.

Financial Snapshot and Risk Factors

Tonbo Imaging's restated financials indicate cyclical moderation in its top line. For the fiscal year ended March 31, 2026, revenue from operations was ₹362.6 crore, dropping 22.7% compared to ₹469 crore in FY25. Restated profit after tax slipped to ₹50.88 crore in FY26 from ₹72.76 crore in the prior fiscal period. Total borrowings as of March 31, 2026, stood at ₹116.06 crore.

As of June 30, 2026, Tonbo held a confirmed order book of ₹314.14 crore, consisting of ₹231.77 crore in domestic orders and ₹82.37 crore in international purchase orders.

Key risks highlighted in the offer filings include high client concentration—with top 10 customers accounting for 77.83% of revenue in FY26—as well as elongated working capital cycles tied to milestone-based procurement and bureaucratic tender delays common to global defence contracting.
