Tonbo Imaging India Shares List at 66% Premium: Stock Debuts at ₹1,160 on NSE

Tonbo Imaging India shares made a strong debut on the stock market on Friday, October 23, 2026, delivering substantial listing gains to investors who received shares in the company's initial public offering (IPO). The shares listed at ₹1,160 on the National Stock Exchange (NSE), a premium of 65.71% over the IPO issue price of ₹700.

On the Bombay Stock Exchange (BSE), Tonbo Imaging shares opened at ₹1,162, representing a listing premium of approximately 66%. Based on the NSE listing price, investors who received one lot of 21 shares could have made a listing profit of ₹9,660, excluding applicable charges and taxes.

Tonbo Imaging IPO Listing Gain: How Much Did Investors Earn?

The Tonbo Imaging India IPO attracted significant investor interest, and its strong stock market debut rewarded successful applicants with substantial paper gains at listing.

The IPO lot size was 21 shares, with an investment of ₹14,700 required at the issue price of ₹700 per share.

Here is how the listing gain works:

IPO issue price: ₹700 per share

Lot size: 21 shares

Minimum investment for one lot: ₹14,700

NSE listing price: ₹1,160 per share

Value of one lot at listing: ₹24,360

Profit at the NSE listing price: ₹9,660

Listing gain: Approximately 65.71%

The calculation shows that the value of a 21-share lot increased from ₹14,700 to ₹24,360 at the NSE listing price.

However, the ₹9,660 gain represents the difference between the issue price and the listing price. The actual profit depends on the price at which an investor sells the shares, along with brokerage, transaction charges, taxes and other applicable costs.

Should Investors Book Listing Gains in Tonbo Imaging Shares?

Tonbo Imaging India's strong listing delivered substantial gains to investors who received IPO allotments. However, a strong debut does not guarantee continued share-price appreciation.

Investors considering the stock after listing should evaluate the company's financial performance, valuation, business outlook, order book and risk factors rather than relying solely on the initial listing premium.

Those who received shares and select to sell should also account for transaction costs and applicable taxes when calculating their final returns.
