Tempsens Instruments IPO Opens With Strong Grey Market Buzz

Tempsens Instruments (India) Limited opened its initial public offering for subscription on Thursday, entering the market with one of the stronger grey market premiums seen among recent mainboard listings and a broadly positive read from brokerage analysts.

Issue Details

The Rs 650-crore offering is structured as a book-built issue combining a fresh issue of Rs 95 crore with an offer for sale worth Rs 555 crore from existing shareholders. Shares are priced in a band of Rs 285 to Rs 300, with retail investors required to bid for a minimum lot of 50 shares, translating to an investment of roughly Rs 14,250 to Rs 15,000 at the lower and upper ends of the band. The issue will remain open for four days, closing on August 24, with allotment expected to be finalized around August 25 and listing tentatively slated for August 28 on both the NSE and BSE.

Ahead of the opening, shares were commanding a grey market premium of around Rs 220, or roughly 73 percent over the upper price band, implying an unofficial expected listing price in the vicinity of Rs 520. Grey market premiums are unofficial and can move quickly before listing, but the scale of the current premium points to healthy pre-listing demand.

About the Company

Tempsens, incorporated in 1990, is a thermal engineering company that manufactures customized temperature-sensing instruments, industrial electrical heaters, and specialized instrumentation cables. The company describes itself as India's largest manufacturer of contact and non-contact temperature sensors by revenue and one of the country's largest makers of electrical heaters, holding roughly a tenth of the domestic temperature-sensor market. It exports to more than 80 countries and operates a network of manufacturing units and distributors that supports both its domestic and international business.

Financial Snapshot

The company's revenue from operations grew from around Rs 275 crore in FY24 to about Rs 379 crore in FY25 and roughly Rs 445 crore in FY26, while profit after tax rose to about Rs 71 crore in the most recent year, with operating margins holding near 25 percent. Over the three-year period, the company posted a compound annual growth rate in the high twenties for both revenue and profit, alongside a conservative balance sheet with a debt-to-equity ratio of about 0.2 times. At the top end of the price band, the issue values the company at a price-to-earnings multiple in the mid-thirties, a level that several brokerages have flagged as reasonable relative to the company's growth and niche market positioning, with a number of analysts assigning "subscribe" ratings ahead of the opening.

What to Watch

Investors will be watching subscription data over the coming days, particularly demand from qualified institutional buyers, which typically firms up in the final one to two days of a book-built issue and tends to be the strongest signal of how the stock might perform on listing day.
