Tonbo Imaging IPO

Tonbo Imaging is a defence electronics original equipment manufacturer that designs, develops and manufactures the sensing, processing, communication and guidance systems used for surveillance, reconnaissance, targeting and fire control. Its portfolio spans thermal imaging cores, weapon sights, hand-held thermal binoculars, targeting systems, missile seekers, fire control systems and missile guidance systems — broadly, the equipment that lets a soldier, a vehicle or a missile see and identify a target in darkness, smoke or bad weather. The company was incorporated in Bengaluru in December 2003 as Sarnoff Innovative Technologies Private Limited and had 339 permanent employees as of 30 June 2026. As of the same date it reported more than 28,000 systems deployed across 24 countries. Two facts in the RHP define its competitive position: per the commissioned Frost & Sullivan report it held a 94% share of India's thermal imaging exports by units shipped between FY24 and FY26, and its EO/IR products are free of US ITAR export controls, which lets it sell into non-aligned and export-sensitive markets that ITAR-bound Western OEMs cannot serve. Since FY24 it has owned 100% of its intellectual property outright, having bought it from CEAQ Singapore under assignment agreements dated 11 March 2024.

Tonbo sells hardware into government and defence procurement, won through competitive tenders rather than recurring contracts — the RHP is explicit that it has no annuity revenue and that customer relationships are typically short-term and tied to a specific product. It keeps design and IP in-house and scales production through certified electronics manufacturing partners rather than owning heavy plant, which is why net tangible fixed asset turnover ran at 14.62× in FY26. Revenue is reported in three product buckets: Tactical systems (soldier-carried electro-optical sights) contributed ₹211.68 Cr of FY26 revenue from operations, Platform systems (optics integrated into vehicles and weapon platforms) ₹144.81 Cr, and OEM component sales ₹1.20 Cr. That mix has swung hard — Tactical was ₹362.30 Cr and Platform only ₹101.05 Cr in FY25. The geographic mix swung harder still: exports were 65.52% of revenue in FY25 and just 5.57% in FY26, as a single large export customer that supplied 57.07% of FY25 revenue fell to 13.78% in FY26. Revenue is also seasonally back-loaded; the RHP notes revenue recognition concentrates in the second half of the financial year, which is why the June quarter shows a loss.
