Tonbo Imaging Secures SEBI Approval For 1.81 Crore Share IPO Via Offer For Sale

Capital markets regulator Securities and Exchange Board of India (SEBI) has cleared the draft red herring prospectus of Bengaluru-headquartered defence electronics maker Tonbo Imaging India Limited, paving the way for its public listing on domestic bourses. The regulator issued its observation letter on the company's offer documents, giving the enterprise a 12-month runway to launch its maiden issue.

Tonbo Imaging had submitted its preliminary papers to SEBI in December 2025. The development comes amid strong secondary market appetite for indigenous defence, aerospace, and strategic deep-tech engineering firms aligned with the government's Atmanirbhar Bharat push.

Issue Structure And Key Details

The proposed initial public offering is structured entirely as an Offer for Sale (OFS), with no fresh issuance of shares. Because there is no primary equity issuance, the company itself will not receive any capital from the public offering; the proceeds will be remitted entirely to the selling shareholders.

The details of the equity dilution outlined in the regulatory filings include:

• Up to 18,085,246 equity shares of face value ₹2 each to be offloaded in the OFS.
• Promoters to offload up to 1,960,000 equity shares.
• Promoter-group entity to sell up to 339,700 equity shares.
• Existing investor selling shareholders to divest up to 15,635,046 equity shares.

JM Financial Limited and IIFL Capital Services Limited have been appointed as the book-running lead managers to orchestrate the public issue.

Company Profile And Product Portfolio

Originally founded in 2003 by technologists with experience at the US Department of Defense and Sarnoff Corporation, Tonbo Imaging pivoted towards commercial and military-grade hardware manufacturing in 2012 following a promoter-led buyout. The company is promoted by Arvind Lakshmikumar, Ankit Kumar, and Cecilia D'Souza.

Tonbo operates an asset-light intellectual property model where core optical, algorithmic, and sensor hardware designs remain proprietary, while contract manufacturing is executed via certified Electronics Manufacturing Services (EMS) partners. The company operates across tactical systems and platform systems, engineering equipment such as:

• Thermal imaging cores, weapon sights, and uncooled night-vision equipment.
• Target acquisition and fire-control systems for armored combat vehicles and naval vessels.
• Multi-spectral infrared seekers, missile guidance heads, and airborne electro-optical gimbals.
• Free-space optical communication platforms and autonomous surveillance systems.

According to industry reports cited in its draft papers, the company accounted for 93% of India's thermal imaging exports in FY25, establishing it as the single largest domestic exporter of advanced electro-optics systems, with deployments spanning 24 countries.

Financial Profile And Order Pipeline

Tonbo Imaging has experienced rapid financial scale alongside the broader expansion in global defence modernisation. For the financial year ended March 31, 2025 (FY25), the company posted:

• Revenue from operations of ₹469.08 crore.
• Profit after tax (PAT) of ₹72.76 crore.

For the quarter ended June 30, 2025, revenue from operations stood at ₹68.68 crore, with profit after tax coming in at ₹5.43 crore. The company held a confirmed order book standing at ₹266.57 crore as of September 30, 2025, and secured additional contracts worth ₹71.68 crore during October and November 2025.

Marquee institutional and venture capital backers participating in or holding stakes around the listing include Qualcomm Ventures, Artiman, Edelweiss Value, Celesta Capital, HBL Engineering, Tenacity Ventures, India Exim Bank, and Florintree. The clearance adds Tonbo to a robust pipeline of technology and manufacturing companies seeking liquidity on Indian exchanges.
