Tonbo Imaging IPO Review: Good or Bad?

Is the Tonbo Imaging IPO good or bad? Going by the numbers, it is a company with real technology, a confirmed order book of Rs. 314.24 crore and an asset-light model, but it asks for a price of about 79 times earnings after a year in which revenue and profit both fell, cash flow turned negative and the first quarter of FY27 was a loss. Whether that trade-off suits you depends on how much risk you can carry, so this article lays out the evidence instead of a one-word verdict.

We read the Red Herring Prospectus (RHP) that Tonbo Imaging India Limited filed with SEBI, dated 10 October 2026, and pulled the figures that matter for an investor. Every number below comes from it unless we name another source. If the document is new to you, our guide to the red herring prospectus explains each section.

Tonbo Imaging IPO Details

Here are the terms you need before you bid. The bidding dates come from the RHP. The RHP leaves the price band and lot size blank, because they are announced separately, so we took them from media reports of the company's announcement. Check them against the final price band advertisement and your bid form.

The quota is the detail to notice. Under Regulation 6(1), retail investors are reserved at least 35% of the net offer and institutions at most 50%. That is a larger retail share than in loss-making IPOs filed under Regulation 6(2), where retail can be limited to 10%. A bigger quota does not guarantee allotment, which depends on how many people bid.

What Does Tonbo Imaging Do?

Tonbo Imaging designs electro-optic and infrared systems for armed forces: thermal cameras, thermal binoculars, targeting and fire-control systems, missile seekers and the sensors for remote weapon stations. Its customers are militaries, security agencies and other defence manufacturers. The company says that between April 2024 and March 2026 it was the largest seller of thermal imaging systems to Indian government and defence agencies by value, and that it held 94% of India's thermal imaging exports by units. Both claims come from a Frost & Sullivan report that Tonbo commissioned and paid for, so treat them as the company's own case.

The business has three features worth knowing:

• Design in-house, make outside. Core design and intellectual property sit in Bengaluru, where 130 engineers work (about 38% of 339 permanent staff). Production is outsourced to electronics manufacturers such as Kaynes Technology and Avalon Technology, so the company needs little factory investment.

• Two product lines. Tactical systems brought in Rs. 211.68 crore in FY26 (58.4% of revenue). Platform systems, which combine several subsystems into one integrated unit, brought Rs. 144.81 crore (39.9%) and have grown from Rs. 12.70 crore in FY24.

• Own technology. Tonbo says it owns 100% of its intellectual property since March 2024, when it bought it from CEAQ Singapore, a shareholder that is also selling in this IPO.

By customer, Indian government bodies gave 71.2% of FY26 revenue and private system integrators 24.1%. Foreign governments gave only 3.3%, down from 57.1% in FY25.

Who Owns Tonbo Imaging and Who Is Selling?

Before the offer the three promoters, Arvind Kondangi Lakshmikumar, Ankit Kumar and Cecilia D'Souza, hold 17.42% together on a fully diluted basis (8.67%, 5.30% and 3.45%). Vinimaya Advisory LLP, a promoter group entity, holds 1.15%. The largest outside holders are CEAQ Singapore (25.47%), HBL Engineering (14.25%) and CEAQ India (8.73%).

Because this is a pure OFS, every share sold comes out of an existing holder's stake:

The two CEAQ entities together sell 91,53,196 shares, about 75.2% of the offer (our calculation). Early investors exiting is common in IPOs and is not a warning sign on its own, but it is why the Rs. 852 crore does not reach the company. Tonbo will not use this issue to build capacity, repay debt or fund working capital, and you should not read it as a fund-raising round.

Tonbo Imaging Financials: Strong Margins, Falling Sales

All figures are restated consolidated numbers in Rs. crore, converted from the RHP's Rs. million figures, for the years ended 31 March.

Three things stand out. First, margins are high for a hardware company. EBITDA margin has stayed between 26% and 30%, which reflects that Tonbo sells its own design rather than assembling someone else's. Second, the top line is not smooth. Revenue grew 9.55% in FY25 and then fell 22.69% in FY26. The RHP puts this down to delays in some international orders because of the West Asia conflict and to some expected orders slipping from FY26 into FY27. Third, returns on equity and capital employed have fallen every year as revenue dropped and the equity base grew.

The April to June 2026 quarter was a loss of Rs. 17.74 crore on Rs. 36.01 crore of revenue. The RHP says the company's revenue is concentrated in the second half of the financial year, so one weak first quarter does not mean the year will be weak. Still, you are paying for FY26 earnings that have already fallen, and the latest quarter did not show a recovery.

Cash Flow: Profit That Did Not Become Cash

For a company that builds equipment to order, cash flow shows what the profit line cannot.

Tonbo reported profits of Rs. 72.76 crore in FY25 and Rs. 50.88 crore in FY26, yet operations used cash in both years. The reason is tied-up money. Inventory rose from Rs. 111.14 crore at March 2025 to Rs. 219.49 crore at March 2026 and Rs. 319.63 crore at June 2026. Working capital days, a measure of how long cash stays locked in the business, went from 152 in FY24 to 280 in FY25 and 517 in FY26. The RHP notes that the June 2026 figure of 1,454 days is not comparable with the annual numbers because of the cyclical pattern of revenue.

One other item sits in FY24 to FY26 cash flow: a one-time purchase of intellectual property from CEAQ Singapore for Rs. 183.19 crore, paid over the three years. The RHP says it was cheaper to buy the IP than to keep paying royalty to a related party. It also means a selling shareholder received that money before the IPO. Ask whether growing orders will release the inventory, because that is what turns the profit into cash.

Order Book, Exports and Customers

Tonbo sells mostly through government tenders, so orders arrive in lumps. The confirmed order book, which counts only contractually confirmed firm orders, was Rs. 563.14 crore at March 2024, Rs. 218.61 crore at March 2025, Rs. 279.02 crore at March 2026 and Rs. 314.24 crore at June 2026. At June 2026 it held 36 orders: 30 domestic worth Rs. 231.87 crore and 6 overseas worth Rs. 82.37 crore. Between July and September 2026 the company received another Rs. 118.15 crore of orders. Rs. 51.44 crore of the June 2026 order book is an export order that slipped from FY26.

The bid win rate gives a second signal. Tonbo won 40.9% of the bids it submitted in FY24, 35.9% in FY25 and 34.4% in FY26 (45 of 131). In April to June 2026 it won 2 of 14, or 14.3%. The sample for the latest quarter is small, so do not read too much into it, but it is a number to track.

Customer concentration is the other thing to check. The top five customers gave 53.0% of FY26 revenue and 92.1% in the June 2026 quarter. In FY25 a single customer alone gave 57.07% of revenue, and in FY24 the same customer gave 44.11%. That customer was not the largest in FY26. Exports followed the same pattern: 48.6% of revenue in FY24, 65.5% in FY25, 5.6% in FY26 and 0.25% in the June 2026 quarter. The company does not disclose customer names, citing defence confidentiality. When one buyer can account for more than half of a year's sales, the order book of the next year can look very different.

Can You Judge the Price?

The RHP lists the P/E ratios of five listed defence companies at 7 October 2026 closing prices, using FY26 diluted earnings per share. Using the reported upper band of Rs. 700 and Tonbo's FY26 diluted EPS of Rs. 8.88, we get a price-to-earnings (P/E) ratio of about 78.8 (our calculation).

On this table Tonbo sits just under the peer average, which can look reasonable. Two cautions apply. First, the peers are established, profitable companies, and several are much larger, so a similar multiple is not the same as a similar quality of earnings. Second, Tonbo's multiple is calculated on a profit that fell 30.1% and was followed by a loss in the latest quarter.

Strengths of the Tonbo Imaging IPO

• Owned technology: Tonbo says it owns 100% of its intellectual property and its infrared portfolio is free of U.S. ITAR export restrictions, which lets it sell to more countries.

• High margins: EBITDA margin of 28.85% in FY26 and gross margin of 51.05%, on an asset-light model.

• Product shift: Platform systems grew from 3.0% of revenue in FY24 to 39.9% in FY26, a move toward bigger integrated contracts.

• Order flow: A confirmed order book of Rs. 314.24 crore at June 2026, plus Rs. 118.15 crore of orders received between July and September 2026.

• Clean audit reports: The auditors report no qualifications, reservations or emphasis of matters for the last three years and the June 2026 quarter.

• No criminal cases: The RHP discloses no outstanding criminal proceedings against the company, its subsidiaries or its directors.

• Retail quota: At least 35% of the net offer is reserved for retail investors.

Risks of the Tonbo Imaging IPO

Tonbo Imaging IPO: Good or Bad?

There is no single answer. This table sets out what points each way.

If you want a company with a steady, growing profit record, this one does not fit yet, because the latest numbers point the other way. If you are willing to back a defence technology company on the strength of its margins and order pipeline, and you can accept lumpy revenue and a high multiple, it is the type of bet some investors make with a small slice of their money. Only you can decide that.

Questions to Settle Before You Bid

1. Can you hold through a quarter or two of weak revenue if tenders are delayed?

2. Are you comfortable paying about 79 times FY26 earnings when FY26 earnings fell?

3. Have you read the RHP's risk factors on customer concentration and on the CEAQ related-party IP purchase?

4. How much of your portfolio would one lot at Rs. 14,700, or 13 lots at Rs. 1,91,100, be, and can you accept a total loss on it?

5. Have you confirmed the final price band and lot size on the exchange websites?
