The initial public offering of Tempsens Instruments (India) Limited has emerged as one of the most closely tracked mainboard issues of the current primary market season, drawing in heavy investor demand and a grey market premium (GMP) that has moved sharply higher through the bidding window.


Issue details
Tempsens Instruments launched its IPO with a price band of ₹285 to ₹300 per share, aiming to raise approximately ₹650 crore. The issue was open for subscription from August 20 to August 24, 2026, with a lot size of 50 shares, translating to a minimum retail investment of around ₹15,000 at the upper end of the band. ICICI Securities Ltd acted as the book-running lead manager, while Kfin Technologies Ltd served as the registrar for the issue.


Subscription demand
The offering saw robust participation across investor categories through its three-day bidding window, with cumulative subscription figures climbing well past 20 times the shares on offer and, by some tracking sources, touching over 60 times overall as the issue drew to a close on August 24. Several brokerages had flagged the issue as one worth watching ahead of the closing day, citing the company's financial profile and sector positioning.


Grey market premium movement
The unofficial grey market premium for Tempsens Instruments shares has been on a steady upward trajectory since bidding opened. GMP was quoted around ₹154 on August 17, rising to roughly ₹220 by August 19, ₹270–₹277 around August 20–21, and touching levels near ₹320–₹330 through August 22–24. As of this morning, August 25, 2026 — the day allotment is being finalised — GMP was being quoted around ₹300, implying an indicative listing price near ₹600 against the ₹300 upper price band, or roughly a 100% premium.


It is important to note that GMP is an unofficial, unregulated indicator of market sentiment. It is not published or endorsed by SEBI or the stock exchanges, and actual listing-day prices can and do diverge from grey market estimates.


Allotment and listing timeline
The basis of allotment for Tempsens Instruments IPO is being finalised today, August 25, 2026. Investors who applied can check their allotment status through the registrar's website (Kfin Technologies) or via the BSE/NSE allotment status portals using their PAN, application number, or demat account details. Shares are expected to be credited to successful applicants' demat accounts by August 27, 2026, ahead of a tentative listing on both BSE and NSE on August 28, 2026.


Company and valuation snapshot
Tempsens Instruments (India) Ltd reported revenue growth of around 19% and profit after tax (PAT) growth of around 14% in its recent financial performance. At the upper price band, the issue is valued at a P/E ratio of approximately 35.38x, with an EPS of ₹8.48, P/B of 4.87, and return on net worth (RoNW) of 13.55%, implying a market capitalisation of roughly ₹2,515 crore. Promoter and promoter group shareholding is expected to reduce from 80.51% before the IPO to 65.67% after the issue, reflecting the dilution typical of a primary offering of this size.
