Company Overview
Tonbo Imaging India Limited was incorporated in December 2003 and is headquartered in Bengaluru. It is a defence electronics original equipment manufacturer that designs and builds electro-optical and infrared imaging systems, embedded vision and autonomous guidance products. It became a defence product company in 2012 following a promoter-led buyout.
The portfolio spans three categories. Tactical Systems include thermal weapon sights, night-vision binoculars and handheld imagers. Platform Systems include multi-sensor gimbals, electro-optical and infrared payloads, and vision subsystems for unmanned aerial vehicles, armoured vehicles, naval turrets and missiles. Directed Energy Systems include radio-frequency and high-power microwave platforms, such as WaveStrike, used to counter drone swarms and aerial threats. The company’s systems are ITAR-free, which allows sales outside traditional Western export-control channels.
The company follows an asset-light manufacturing model, outsourcing production to electronics manufacturing services partners including Kaynes Technology India and Avalon Technology and Services. It has owned 100% of its electro-optical and infrared intellectual property since Fiscal 2024, holds five patents granted by the United States Patent and Trademark Office, and had 339 permanent employees as of June 30, 2026. More than 28,000 of its systems have been deployed across 24 countries. Its confirmed order book stood at ₹314.24 crore as of June 2026, with a further ₹118.15 crore of orders received between July and September 2026.

(Compiled from RHP and market updates)
Industry Context
- India’s defence exports reached ₹38,424 crore in Fiscal 2026, an increase of 62.66% over the previous year according to the Ministry of Defence, reflecting the policy push toward indigenous manufacture and export of defence equipment.
- Within thermal imaging, the Indian market is concentrated. Tonbo Imaging accounted for 94% of India’s thermal imaging export volume by units between April 2024 and March 2026, with all other Indian exporters making up the remaining 6%. In supplies to Indian government customers over the same period, Tonbo accounted for 51% of thermal imaging systems by units, ahead of Tata Advanced Systems at 16%, with other suppliers accounting for 33%.
- India’s Technology Perspective and Capability Roadmap 2025 identifies potential requirements of 55,000 to 60,000 thermal imaging sights, 20,000 to 50,000 anti-tank guided missiles and 3,000 to 3,200 driver night sights. These are stated programme opportunities for the industry rather than confirmed orders for any single supplier.
- Export orientation varies widely across listed Indian defence companies. In Fiscal 2025, exports contributed 65.52% of Tonbo Imaging’s revenue, against 37.97% for Zen Technologies, 15.00% for Data Patterns, 14.59% for Paras Defence, 10.00% for Astra Microwave and 3.86% for Bharat Electronics.
- Indigenously Designed, Developed and Manufactured supplier status under the Defence Acquisition Procedure 2020, together with ITAR-free system design, determines which suppliers can access domestic procurement preference and which export markets are open to them.
Business Strengths
- A leading position in Indian thermal imaging, accounting for 94% of India’s thermal imaging export volume by units and 51% of thermal imaging systems supplied to Indian government customers between April 2024 and March 2026, per the Frost & Sullivan report.
- A portfolio spanning tactical systems, platform systems and directed energy systems, with more than 28,000 systems deployed across 24 countries, serving militaries, homeland security agencies and global original equipment manufacturers.
- ITAR-free system design combined with Indigenously Designed, Developed and Manufactured supplier status under the Defence Acquisition Procedure 2020, which opens export markets outside Western export-control channels while qualifying the company for preference in Indian defence procurement.
- Full ownership of its electro-optical and infrared intellectual property since Fiscal 2024, supported by in-house research and development and five patents granted by the United States Patent and Trademark Office.
- An asset-light manufacturing model that outsources production to electronics manufacturing services partners including Kaynes Technology India and Avalon Technology and Services, with a confirmed order book of ₹314.24 crore as of June 2026 and a further ₹118.15 crore of orders received between July and September 2026.
Business Risks
- The issue is entirely an Offer for Sale, so the company receives no proceeds and the full amount, net of offer expenses and taxes, goes to the selling shareholders. Promoter and promoter group holding is 18.58% before the issue and falls to 15.72% after it, and the two largest sellers are the investor entities CEAQ Technologies Private Limited and CEAQ Technologies Pte. Limited, which together account for about three-quarters of the shares offered.
- Fiscal 2026 was a year of decline. Revenue from operations fell 22.69% to ₹362.65 crore and profit after tax fell 30.07% to ₹50.88 crore. Export revenue fell 93.42% to ₹20.21 crore, dropping to 5.57% of revenue from 65.52% in Fiscal 2025, which the offer document attributes to delays in executing certain international orders arising from the West Asia conflict and to anticipated orders being pushed from Fiscal 2026 into Fiscal 2027. Domestic revenue rose 114.89% to ₹337.47 crore but did not offset the export decline.
- The three months ended June 30, 2026 were loss-making. The company reported total income of ₹37.32 crore, EBITDA of negative ₹13.04 crore and a loss after tax of ₹17.74 crore, against a profit of ₹50.88 crore for the full Fiscal 2026.
- Cash flow from operating activities was negative ₹63.22 crore in Fiscal 2026 and negative ₹136.12 crore in Fiscal 2025. Revenue is order-driven and lumpy, and the five largest customers accounted for 53.03% of Fiscal 2026 revenue, so performance depends on the timing and execution of a small number of large contracts.
- At the upper price band the issue is priced at about 78.8 times Fiscal 2026 earnings and 7.25 times book value, against earnings that declined in Fiscal 2026 and a loss in the most recent reported quarter. The company also depends on third-party electronics manufacturing partners for production rather than owned facilities.

Conclusion
Tonbo Imaging India Limited develops imaging systems for defence and homeland security. While it has a strong position in India’s thermal imaging market, its financial performance has weakened. Revenue fell 22.69% to ₹362.65 crore in FY26, while profit declined 30.07% to ₹50.88 crore. Export revenue dropped sharply, and the company reported a loss in the quarter ended June 2026.
Other risks include customer concentration, negative operating cash flow and dependence on manufacturing partners. The IPO is entirely an Offer for Sale, and its valuation needs careful consideration amid declining earnings. Investors should review the RHP before making a decision.
