Quick Answer
Tonbo Imaging shares extended their gains on 26 Oct, rising as much as 17.3% to Rs 1,330.50 before easing to about Rs 1,243.30, while the headline says analysts suggest allotted investors consider partial profit-booking or holding for the long term.

From Issue to Listing: What Happened to Tonbo Imaging Shares
| Tonbo Imaging shares: issue and listing item | Detail |
|---|---|
| Price band | Rs 665 to Rs 700 per share |
| Issue size | Rs 852.18 crore, entirely an offer for sale of about 1.22 crore shares |
| Bidding dates | 15 Oct to 19 Oct 2026 |
| Lot size | 21 shares, about Rs 14,700 at the upper band |
| Overall subscription | 135.90 times |
| QIB, NII and retail subscription | 293.56 times, 170.94 times and 31.07 times |
| Employees | 54.31 times |
| Anchor book | Rs 255.36 crore from 36,48,013 shares |
| Listing price | Rs 1,162 on BSE and Rs 1,160 on NSE, about a 66% premium |
| Listing-day close (23 Oct) | Rs 1,133.80, about 2.3% below the NSE listing price (my calculation) |
Because the Tonbo Imaging subscription was heavy but the issue was an offer for sale, existing shareholders sold shares and the company did not receive proceeds. The anchor book included SBI, ICICI Prudential, HDFC and Kotak mutual funds, HDFC Life, Goldman Sachs, BlackRock, Allianz Global Investors and Prudential Assurance. Demand from qualified institutional buyers (QIB) of 293.56 times and from non-institutional investors of 170.94 times explains why the Tonbo Imaging listing was so strong, and the Tonbo Imaging subscription data is the main reason Tonbo Imaging shares still attract buyers.
Business and Financials Behind Tonbo Imaging Shares
| Tonbo Imaging shares: financial item | Figure | Comparison |
|---|---|---|
| FY26 revenue from operations | Rs 362.65 crore | Down 22.7% from Rs 469.08 crore |
| FY26 profit after tax | Rs 50.88 crore | Down about 30.1% from Rs 72.76 crore (my calculation) |
| Q1 FY27 revenue | Rs 36.01 crore | Quarterly figure |
| Q1 FY27 net loss | Rs 17.74 crore | Loss-making quarter |
Tonbo is a Bengaluru-based defence electronics company with systems deployed in 24 countries, making thermal imaging systems, weapon sights, missile seekers and fire-control systems for surveillance, reconnaissance and targeting. The fall in FY26 revenue was attributed to delayed international orders linked to the West Asia conflict, with some orders deferred to FY27, according to Business Standard.
The Q1 FY27 loss of Rs 17.74 crore on revenue of Rs 36.01 crore is the figure that sits uncomfortably with a price gain of about 77.6%. The business is lumpy and depends on order timing, so one quarter does not decide the year, but it does mean that the share price now reflects expected recovery.
Valuation: What the Market Pays for Tonbo Imaging Shares
| Tonbo Imaging shares: valuation (data provider) | Reading |
|---|---|
| Market capitalisation | About Rs 6,494 crore |
| Price to earnings (trailing) | 127.66 against an industry level of 45.08 |
| Price to book | 11.74 |
| Earnings per share | Rs 8.88 |
| Book value per share | Rs 96.57 |
| Debt to equity | 0.26 |
| Market capitalisation to FY26 revenue | About 17.9 times (my calculation) |
At about 2.8 times the industry price to earnings (my calculation), Tonbo Imaging shares are priced for a strong recovery in orders and profit. The secondary transactions of more than Rs 413 crore at Rs 700 per share before the issue valued the company at about Rs 4,000 crore on a fully diluted basis, so the market capitalisation has risen sharply since.

Price Levels for Tonbo Imaging Shares
| Tonbo Imaging shares: level | Rs | What it marks |
|---|---|---|
| Resistance | 1,330.50 | Today’s intraday high |
| Support 1 | 1,196.75 | Today’s low |
| Support 2 | 1,160 to 1,162 | Listing prices on NSE and BSE |
| Support 3 | 1,133.80 | Listing-day close |
| Reference | 700 | Issue price |
The Tonbo Imaging share price has only four sessions of history, so Tonbo Imaging shares have no reliable averages yet, and the Tonbo Imaging listing prices act as the first support. The Tonbo Imaging subscription of 135.90 times and the Tonbo Imaging listing at a 66% premium explain the demand, but a Tonbo Imaging share price at this level needs earnings to follow. A newly listed stock has little chart history, so there are no reliable averages or trend indicators yet. The levels above come from the first four sessions, and a close below the listing prices of Rs 1,160 to Rs 1,162 would mean that the post-listing gains in Tonbo Imaging shares are being tested. These levels are not forecasts.
Buy, Sell or Hold Tonbo Imaging Shares: A Framework
| Investor type | Things to weigh | What the headline suggests |
|---|---|---|
| Allotted investor with a large gain | A gain of about 77.6% in four sessions against falling revenue and a loss in Q1 | Consider partial profit-booking |
| Allotted investor with a long horizon | Order execution, international demand and defence spending | Consider holding for the long term |
| New buyer | A price to earnings of 127.66 and a price already far above the issue price | Caution is warranted, as one analysis puts it |
On a 21-share lot, the gain at Rs 1,243.30 is about Rs 11,409 and at the day high about Rs 13,241 (my calculation). Partial profit-booking locks in some of that gain while keeping exposure, and holding keeps the full exposure to the business. Neither is a recommendation, and I could not retrieve the named analysts’ quotes behind the headline, so please read their original notes.
Grey Market Premium and Tonbo Imaging Shares
Grey market premium (GMP) is an unofficial, unregulated indicator that is not endorsed by SEBI, NSE, or BSE. Investors looking for indicative GMP data can go through other relevant sources, though such figures should never be the sole basis for an investment decision.
This article does not quote grey market numbers. The official facts, which are the issue price, subscription, financials and live prices, are a better base for any decision.
Risks to Check Before You Buy, Sell or Hold
- Valuation risk. For Tonbo Imaging shares, a price to earnings of 127.66 leaves little room for a miss.
- Earnings risk. FY26 revenue fell 22.7% and Q1 FY27 was loss-making.
- Order risk. Defence orders can be delayed, as the West Asia conflict showed.
- Supply risk. Shares held by anchor investors and pre-issue holders become tradable in stages under the lock-in rules, so please check the prospectus for dates.
- Volatility. The stock moved from Rs 1,196.75 to Rs 1,330.50 in a single morning, so stop-loss planning matters.
Conclusion
Tonbo Imaging shares rose as much as 17.3% to Rs 1,330.50 on 26 Oct and trade about 77.6% above the issue price, but revenue fell in FY26, Q1 FY27 was a loss and the valuation is high. Analysts quoted in the headline suggest partial profit-booking or a long-term hold. Check the facts and decide according to your own risk profile.
