Tonbo Imaging IPO Fully Subscribed on Day 1 Driven by Retail and NII Demand

The initial public offering (IPO) of Bengaluru-based defence electronics manufacturer Tonbo Imaging India Limited was fully subscribed on Thursday, October 15, 2026, within hours of opening for bidding. Strong interest from non-institutional investors (NIIs) and retail individual investors pushed the overall subscription past the 100% mark on Day 1, supported by upbeat sentiment surrounding India's indigenous defence manufacturing ecosystem.

The public offer, which is scheduled to close on Monday, October 19, 2026, consists entirely of an Offer for Sale (OFS) of up to 1,21,74,046 equity shares of face value Rs 2 each, aggregating to approximately Rs 852.18 crore. Since the issue is purely an OFS by promoters and early investors, the company will not receive any capital proceeds from the transaction.

Issue Structure and Anchor Allocation

Tonbo Imaging has set its price band at Rs 665 to Rs 700 per equity share, with a market lot of 21 shares requiring a minimum investment of Rs 14,700 for retail applicants.

Ahead of the opening, the company mobilised Rs 255.36 crore from 43 institutional anchor investors on October 14, allotting 36,48,013 equity shares at the upper price band of Rs 700 apiece. The net public offer reserves 50% for Qualified Institutional Buyers (QIBs), 15% for Non-Institutional Investors (NIIs), and 35% for Retail Individual Investors (RIIs).

In the unlisted market, shares of Tonbo Imaging were commanding a grey market premium (GMP) in the range of 67% to 71%, indicating expectations of strong listing gains. Tentative timelines indicate share allotment will be finalised on October 21, followed by listing on the BSE and the National Stock Exchange (NSE) on October 23, 2026.

Financial Snapshot

Tonbo Imaging specialises in electro-optical, infrared (EO/IR), embedded vision, and surveillance technologies for defence applications across 24 countries. For the financial year ended March 31, 2026 (FY26), the company posted:

• Revenue from operations of Rs 362.65 crore, declining 22.7% from Rs 469.08 crore in FY25 due to delayed international order execution amidst geopolitical developments.
• Profit after tax (PAT) of Rs 50.88 crore, down 30% compared to Rs 72.76 crore in the previous financial year.
• First-quarter performance for FY27 registered revenue of Rs 36.01 crore with a net loss of Rs 17.74 crore, largely reflecting seasonality and deferred contract execution.

At the upper price band of Rs 700, the company commands a market capitalisation of approximately Rs 4,010 crore.

What Brokerages Recommend

Domestic brokerages remain constructive on Tonbo Imaging's niche technological moat, while advising investors to weigh rich valuations and customer concentration risks.

ICICI Direct on Growth Visibility: * The brokerage assigned a Subscribe rating to the issue, noting that future visibility is backed by execution turnaround, non-ITAR compliant design architecture, and sustained margins. While the valuation stands at roughly 80 times FY26 price-to-earnings (P/E) and 11 times market-cap-to-sales, it views the long-term runway favorably while cautioning against extended working capital cycles and tender dependency.

BP Equities on Indigenous Moat: * Assigning a Subscribe rating, BP Equities pointed to Tonbo's alignment with the Ministry of Defence’s Buy (Indian-IDDM) mandate and an active confirmed order book of Rs 314.2 crore. The brokerage underscored that Tonbo's proprietary thermal imaging core technology creates substantial barriers to entry, even as working capital days remain elevated.

JM Financial Limited and IIFL Capital Services Limited are serving as the book-running lead managers to the offering, with KFin Technologies acting as the registrar.
