Tempsens Instruments IPO: Grey Market Surge Pushes Potential Listing Gains Past 43% Ahead of August 20 Launch​

Tempsens Instruments, a Rajasthan-based manufacturer specializing in advanced temperature sensors and electrical heating solutions, is attracting significant speculative interest ahead of its Initial Public Offering (IPO). The company's unofficial grey market premium (GMP) suggests a potential listing gain exceeding 43 percent over the upper end of its price band.

The IPO is scheduled to open for subscription on August 20 and close on August 24, with the anchor investor bidding set for August 19. This marks Tempsens Instruments as the sixth major board IPO this week, following other market entries like Lalithaa Jewellery Mart and Horizon Industrial Parks.

Grey Market Premium and Indicative Listing Price​

The company has fixed a price band for its Rs 650-crore IPO at Rs 285 to Rs 300 per share. Based on current grey market sentiment, the GMP stands at Rs 130 over the upper price band of Rs 300. This translates to an indicative listing price approximating Rs 430 if the current grey-market trend continues.

It is crucial for prospective investors to note that these grey market premiums are unofficial and are based purely on market speculation, not a guarantee of actual listing gains or reflection of company fundamentals. At the upper price band, the IPO represents a potential market capitalization of around Rs 2,515 crore.

IPO Structure and Investor Allocation​

The issue is structured to include both a fresh share sale of Rs 95 crore and an Offer for Sale (OFS) comprising 1.85 crore equity shares worth Rs 555 crore. The proceeds generated from the OFS component, however, will not be received by Tempsens Instruments as existing shareholders are selling their stakes.

The net issue is allocated across various investor categories. Qualified Institutional Buyers (QIBs) have been reserved 50 percent of the issue. Retail investors are allocated 35 percent, while Non-Institutional Investors (NIIs) receive 15 percent. The company has also set aside shares worth Rs 1.5 crore for its employees.

Application Details and Timeline​

The minimum bid size for this IPO is set at 50 shares. Considering the upper price band of Rs 300, a retail investor must make a minimum investment of Rs 15,000 to apply. The maximum application limit is 650 shares, requiring a total payment of Rs 1.95 lakh.

The IPO allotment is expected to be finalized by August 25, with the company's stock scheduled for listing on the exchanges on August 28. ICICI Securities and JM Financial are serving as the book-running lead managers for this issue.

Corporate Financials and Use of Proceeds​

Tempsens Instruments demonstrated steady growth in its financial performance for the period ending March 2026. The company reported a profit of Rs 67.3 crore for FY26, an improvement from Rs 60.6 crore in the preceding year.

Revenue increased by 17.5 percent year-on-year, reaching Rs 444.9 crore in FY26 from Rs 378.5 crore in FY25. The management plans to strategically deploy a portion of the net fresh issue proceeds. Rs 18.1 crore is earmarked for capital expenditure related to its electrical heating solutions and specialised cable solutions businesses.

Furthermore, another Rs 55 crore will be allocated towards debt repayment, with the remainder of the funds designated for general corporate purposes.
