| Date | GMP | Est. Gain |
|---|---|---|
| 13 Oct | +₹460 | +65.7% |
| 12 Oct | +₹420 | +60.0% |
Est. gain = GMP as % of the upper band price (indicative listing premium).
Unlisted shares of Tonbo Imaging India are changing hands at a premium of +₹460 over the issue price, with the premium climbing through the day. That implies an indicative listing near ₹1,160, roughly +65.7% above the upper band. For one retail lot of 21 shares, that translates to an estimated paper profit of about ₹9,660.
GMP is an unofficial, unregulated market signal. It moves daily and does not guarantee the actual listing price. The grey market premium is an unofficial, off-exchange quote where shares change hands before listing. A rising GMP usually means the market expects a strong debut; a fading one suggests cooling enthusiasm. SEBI does not recognise grey-market trades, there is no settlement guarantee, and the actual listing price is decided by normal order-book demand on debut day.
Plan your bid with our unique tools — all calculations run in your browser:
One market lot comprises 21 shares. Applications above ₹2 lakh fall under the non-institutional (HNI) category.
Mark these dates, the full subscription-to-listing cycle typically wraps up in under two weeks. India now runs on a T+3 settlement cycle, meaning bidding closes, allotment is finalised and shares hit Demat accounts within roughly three working days of the close, with listing following the very next trading day. Refunds for unsuccessful applicants happen automatically, ASBA/UPI blocks are released without any forms or follow-ups:
Subscription figures will appear here once bidding opens and the registrar/exchange begins publishing demand data.
QIB demand reflects what mutual funds, insurers and alternative funds think of the valuation; NII (HNI) bookings often track expected listing pops; retail demand shows crowd sentiment. A book that is strong across all three categories is far more reassuring than one carried by a single segment. Remember: heavier oversubscription also means a lottery-style retail allotment, so apply only what you can comfortably bid for.
Here is how the books have moved over the last three financial years:
| Particulars | 30 Jun 2026 | 31 Mar 2026 | 31 Mar 2025 |
|---|---|---|---|
| Assets | 782.87 | 782.50 | 726.36 |
| Total Income | 37.32 | 369.94 | 474.39 |
| Net Worth | 538.54 | 553.16 | 490.14 |
| Reserves | 527.08 | 541.70 | 489.41 |
| Total Borrowings | 129.72 | 116.06 | 78.14 |
All figures in ₹ Crore unless stated otherwise. Source: restated financials disclosed in the offer documents.
Total change is the full swing from the oldest to the newest restated year and is what the Financial Growth score uses. CAGR is the same journey expressed per year, which stops a small base year from making a large-looking jump. Margin is profit after tax as a share of total income.
the borrowings-to-net-worth ratio has climbed to about 0.24. For investors, the trend matters more than any single year, steady compounding with contained leverage is what institutional bidders typically reward, while a late spike in borrowings deserves scrutiny against the stated objects of the issue.
Reading these numbers. RoE and RoCE measure how efficiently the business turns shareholder capital into profit; anything in double digits is respectable, mid-twenties plus is strong. A debt-to-equity ratio well below 1 signals a balance sheet that does not depend on lenders. NAV per share anchors the book value of your bid, while price-to-book tells you how many rupees the issue is charging for each rupee of that book, compare it with listed peers in the same sector before deciding whether the premium is justified.
As disclosed under "Competitive Strengths" in the company's offer document.
Promoter holding comes down after the issue. Some dilution is inherent to every IPO, the question is whether the fresh-money component is funding growth (capacity, debt reduction) or simply an exit for early shareholders. Weigh the split between the fresh issue and the offer-for-sale alongside this number before forming a view.

Grey-market math points to an indicative listing near ₹1,160 (+65.7%); with an AI-predicted listing move of 50.4%.
New listings open with a special pre-open call auction: the exchange matches buy and sell orders to discover an opening price, after which normal trading begins. Newly listed counters trade in price bands (circuit limits) on day one, which caps how far the stock can swing from its base price. If you applied and were allotted, shares are already in your Demat before the bell, you can sell at open or hold; if you missed the allotment, you can still buy on debut, but chasing a euphoric opening is a well-known way to overpay.

You can apply through any UPI-enabled broking app (Zerodha, Groww, Upstox, Angel One etc.) or via ASBA through your bank's net-banking. One lot is the minimum application; retail applications are capped at ₹2 lakh.
Subscription shows how many times the shares on offer were bid for. A figure above 1x means the category is oversubscribed. Higher retail and QIB demand generally signals stronger conviction, though it also means lottery-based allotment.
