As per the F&S Report, Tonbo Imaging India Limited was the largest manufacturer of thermal imaging systems supplied to government and defence agencies in India by sales value between April 2024 and March 2026. The company also accounted for 94% of India's thermal imaging exports by units during this period.
As of June 30, 2026, the company had deployed over 28,000 tactical systems across 24 countries. Its products have been supplied to defence and security customers in markets including India, the USA, Romania, Armenia, South Korea, the UAE, and Australia.
The company claims to own 100% of the intellectual property used in its products since FY24, following the acquisition of intellectual property worth Rs 183.19 crore from CEAQ Singapore in March 2024. Its technologies cover infrared imaging, optics, embedded software, AI-based image processing and electronic systems.
The company operates an R&D centre in Bengaluru, which employs 130 engineers, representing 38.35% of its workforce as of June 30, 2026. Its R&D expenditure increased from Rs 4.24 crore in FY24 to Rs 9.09 crore in FY25 and Rs 25.86 crore in FY26.
The company follows an asset-light manufacturing model, outsourcing production to electronics manufacturing services partners, including Kaynes Technology India Limited and Avalon Technology and Services Private Limited. It retains in-house control over product design, development and core technologies.
The company's R&D centre is ISO 9001:2015 certified for quality management systems, ISO 14001:2015 for environmental management systems, ISO/IEC 27001:2022 for information security management systems, and ISO 28000:2022 for security and resilience management systems.
The company offers a diversified portfolio of tactical and platform systems used in ground, aerial, naval, and missile applications. Its products include thermal weapon sights, handheld imaging systems, stabilised multi-sensor gimbals, fire control systems and missile seekers, serving different defence operational requirements.
The company's revenue from operations stood at Rs 428.19 crore, Rs 469.08 crore, and Rs 362.65 crore in FY24, FY25, and FY26, respectively, recording a decline of 22.69% in FY26. The decline was primarily attributed to delays in international orders arising from the West Asia conflict and the deferment of certain anticipated orders to FY27.
The company's top 10 customers contributed Rs 361.81 crore (84.50%), Rs 447.92 crore (95.49%), and Rs 282.22 crore (77.83%) to its revenue from operations in FY24, FY25, and FY26, respectively. Any failure to retain these key customers, expand its customer base, or secure new contracts could adversely affect the company's business and financial standing.
The company's top 10 suppliers accounted for Rs 227.39 crore (67.49%), Rs 132.74 crore (35.46%), and Rs 206.27 crore (68.77%) of its total expenses in FY24, FY25, and FY26, respectively. The company does not have long-term agreements with its raw material suppliers, and any disruption in these relationships could adversely affect its operations.
The company relies on a limited number of international suppliers for critical components such as infrared sensors, OLED microdisplays, and specialised optics. Procurement of critical components from international suppliers amounted to Rs 90.67 crore, Rs 107.34 crore, and Rs 97.05 crore in FY24, FY25, and FY26, respectively. Any export restrictions, supply disruptions or price increases could adversely affect its production and profitability.
The company's revenue from customers located outside India stood at Rs 208.15 crore (48.61%), Rs 307.34 crore (65.52%), and Rs 20.21 crore (5.57%) in FY24, FY25, and FY26, respectively. Any adverse political, economic, or regulatory developments in its export markets, particularly Europe, could negatively impact its business and financial performance.
The company derives a significant portion of its revenue from tactical systems, which contributed Rs 359.27 crore (83.90%), Rs 362.30 crore (77.24%), and Rs 211.67 crore (58.37%) to revenue from operations in FY24, FY25, and FY26, respectively. Any decline in demand for these products could adversely affect its revenue and profitability.
The company recorded negative cash flows from operating activities amounting to Rs 136.12 crore and Rs 63.22 crore in FY25 and FY26, respectively, and Rs 14.68 crore in the three months ended June 30, 2026. The negative cash flows in FY25 were primarily due to an increase in trade receivables and other non-current financial assets, along with a decrease in other current liabilities related to the one-time intellectual property acquisition in FY24. In FY26 and the three months ended June 30, 2026, the outflows were mainly attributable to increased inventory requirements, changes in other current assets and provisions, and working capital adjustments. Continued negative operating cash flows could create liquidity challenges for the company.
The company incurred liquidated damages amounting to Rs 21.82 crore, Rs 18.93 crore, and Rs 3.80 crore in FY24, FY25, and FY26, respectively, due to delays in meeting contractual delivery schedules. Its defence contracts also contain stringent warranty obligations, and further delays or product defects could result in additional penalties and replacement costs.
The company depends significantly on its Bengaluru R&D centre, where it designs and develops pilot engineering units before outsourcing large-scale manufacturing. Any adverse political, social or economic developments in Karnataka, or disruptions at this facility, could negatively affect its product development and business operations.
As of August 31, 2026, the company had outstanding financial indebtedness of Rs 246.25 crore. Any failure to service or repay these loans can harm the company’s operations and financial position.
