Tempsens Instruments IPO Day 2 Subscription Status

The ₹650 crore issue received bids for about 11.43 crore shares against roughly 1.52 crore shares available for public bidding, taking overall demand to about 7.53 times in the adopted National Stock Exchange of India (NSE) update.

Investor category	Day 2	Day 1 close	Change
Qualified Institutional Buyers (QIBs)	About 1.20x	0.05x	About +1.15x
Non-Institutional Investors (NIIs)	16.99x	12.51x	+4.48x
Retail Individual Investors	7.14x	6.48x	+0.66x
Overall	About 7.53x	5.95x	About +1.58x

NIIs remained the most heavily subscribed category, while retail demand continued to build. QIB participation, which was only 0.05 times at the Day 1 close, also increased materially by the adopted Day 2 update. The QIB multiple is approximately derived from the exchange bid totals and category allocations because the adopted update did not separately state the rounded QIB multiple.

Subscription multiples measure bid quantity relative to shares reserved, not the number of unique applicants.

How Subscription Changed From Day 1

Overall subscription increased from 5.95 times at the Day 1 close to about 7.53 times by early afternoon on Day 2, an absolute rise of roughly 1.58 times.

The largest category-level increase came from NIIs, whose subscription moved from 12.51 times to 16.99 times. Retail demand increased more moderately from 6.48 times to 7.14 times.

The other notable change was institutional participation. QIB demand had been minimal on Day 1 but moved above full coverage on Day 2 based on the adopted exchange totals. That makes the demand mix broader than it was at the end of the opening session, although the NII category still leads by a wide margin.

Tempsens Instruments IPO GMP Today and Estimated Listing Price

Tempsens Instruments IPO GMP was around ₹270 on 21 August 2026. One previous available tracker reading was ₹259 on 20 August, indicating an increase of ₹11. Other grey-market trackers have shown somewhat different figures, so the premium should be treated as an indicative, unofficial reading rather than a single authoritative market price.

GMP observation	Premium	Movement
Current, 21 August 2026	₹270	Up
Previous available reading, 20 August 2026	₹259	+₹11
Other current tracker reading	Around ₹260	Tracker variation

At the upper price band of ₹300, a ₹270 GMP implies an indicative price of ₹570 per share.

Indicative price: ₹300 + ₹270 = ₹570

GMP percentage: ₹270 ÷ ₹300 × 100 = 90.0%

GMP is unofficial, unregulated, and can change quickly. It is not published by the Securities and Exchange Board of India (SEBI), NSE, or BSE Limited (BSE), and it does not guarantee the actual listing price or returns.

What Stands Out in Today’s Bidding

The first notable signal is the continued NII demand. At 16.99 times, this category has added the largest subscription multiple since the Day 1 close. Retail demand has also remained above seven times.

Second, institutional participation has improved from its very low Day 1 base. This makes Day 2 demand less concentrated than the opening-day figures suggested.

There are important limitations. NIIs still account for the highest category multiple, and the relative size of each reserved category affects how quickly its subscription ratio can rise. Also, a 7.53 times overall subscription and a high GMP do not establish fair valuation, business quality, or future returns.

Brief Company and Financial Context

Tempsens Instruments manufactures temperature-sensing solutions, electrical heating systems, and specialised cables for industrial applications. Its domestic operations account for the majority of business, alongside exports to international markets.

For financial year 2025-26, total revenue was about ₹455.86 crore, while profit after tax stood at ₹71.07 crore, both higher than the previous year. Fresh-issue proceeds are intended mainly for capital expenditure in electrical heating and specialised cable operations, debt repayment, and general corporate purposes. A key consideration is valuation, with the upper price band implying an earnings multiple in the mid-30s based on FY26 figures.

What Happens Next

The IPO moves to its closing day on 24 August 2026. Investors can monitor whether overall subscription accelerates, whether QIB participation increases further, whether NIIs continue to lead, and whether retail demand and the GMP maintain their current direction. Final subscription figures should be assessed only after bidding closes and exchange data stabilises.
