Tempsens Instruments Doubles on Debut After ₹650 Crore IPO
Tempsens Instruments (India) made a powerful debut on the Indian stock exchanges on Friday, with its shares listing at more than double the ₹300 IPO issue price.
The stock opened at ₹634 on the NSE, representing a 111.33% premium to the issue price. On the BSE, it began trading at ₹631.20, a gain of 110.40%. The company trades under the symbol TEMPSENS on the NSE and carries the BSE code 544886.
The debut followed an unusually strong response to Tempsens Instruments’ ₹650 crore initial public offering, which was subscribed 184.07 times between August 20 and August 24.
Tempsens Instruments stock price falls from opening level
Although the shares began the session at more than ₹630, they moved lower during morning trading.
HDFC Securities’ brokerage platform HDFC Sky reported that the stock was at ₹609.10 on the NSE and BSE at 10:20:36 a.m. IST, down 3.93% from the ₹634 NSE opening price.
Later market snapshots showed further intraday movement. Business Standard reported Tempsens Instruments at ₹578.05 at 2:09 p.m. IST, while Moneycontrol’s market data showed the stock at ₹568.55 at 1:23 p.m., with an intraday range extending from roughly ₹551 to ₹635.
Because the stock had only begun trading on Friday, there was no established 52-week trading history beyond its IPO price and debut session. The ₹300 issue price therefore provides the immediate reference point for measuring its listing performance.
IPO demand was exceptionally strong
The scale of demand was one of the defining features of the Tempsens Instruments IPO.
The issue was subscribed 184.07 times overall. Qualified institutional buyers subscribed 302.88 times their allocated portion, while the non-institutional investor category was subscribed 314.44 times. The retail portion was subscribed 60.69 times.
The IPO had a price band of ₹285 to ₹300 per share, with a lot size of 50 shares. At the upper end of the price band, a retail investor needed ₹15,000 to apply for one lot.
The ₹650 crore issue consisted of a fresh issue of about ₹95 crore and an offer for sale of approximately ₹555 crore. The company had said that part of the fresh proceeds would be used for capital expenditure and ₹55 crore would go toward debt repayment, with the balance intended for general corporate purposes.
What Tempsens Instruments does
Tempsens Instruments is an India-based manufacturer focused on temperature sensing solutions, electrical heating solutions and specialised cables.
The company operates manufacturing facilities through its subsidiaries and joint ventures, with 15 units globally, including 10 in Udaipur, according to information released around the IPO. It has also described itself as a significant player in temperature sensors and electrical heating equipment.
Its business includes both contact and non-contact temperature measurement products, as well as industrial heating systems and specialised cables used in industrial applications.
The company’s financial performance had also strengthened ahead of the listing. Its revenue from operations reached about ₹444.9 crore in fiscal 2026, compared with ₹378.5 crore in fiscal 2025, according to IPO-related financial disclosures. Profit after tax was reported at roughly ₹67.3 crore for fiscal 2026, compared with ₹60.6 crore a year earlier in the figures cited by Moneycontrol.
Restated consolidated financial information cited in IPO materials puts fiscal 2026 revenue at about ₹444.88 crore and net profit at ₹71.07 crore, reflecting differences that can arise from the presentation of financial information and consolidation adjustments.
India’s strongest IPO debut of 2026
Reuters reported that Tempsens Instruments’ first-day performance represented the largest IPO listing gain in India so far in 2026, with the stock more than doubling from its issue price.
The performance also stood out against a broader Indian equity market that was relatively subdued on Friday. The Nifty 50 ended the session at 24,175.65, while the Sensex closed at 77,264.51, according to Reuters.
For investors who received shares in the IPO, the initial listing premium was substantial. But the movement below the opening price during the first session also showed how quickly prices can change once an IPO begins unrestricted exchange trading.
The stock’s first-day performance should therefore be separated from the company’s underlying business performance. The debut reflects the price at which investors were willing to trade the newly listed shares; it does not by itself establish the company’s long-term valuation.
What happens next for Tempsens shares
Tempsens Instruments will now trade as a listed company on both the NSE and BSE, with its share price determined by regular market trading.
The immediate focus will shift from the IPO’s subscription and listing premium to the company’s quarterly financial performance, business growth, margins, debt position, and ability to deploy the IPO proceeds.
For now, the key fact is clear: Tempsens Instruments entered the public market at more than twice its ₹300 issue price, although the stock moved significantly below its ₹634 NSE opening level during the first trading session.
