Tempsens Instruments India IPO Date, Review, Price and Allotment Details
The Tempsens Instruments India IPO is attracting strong investor attention as the ₹650 crore issue enters its final day of bidding on August 24, 2026. The IPO opened on August 20 with a price band of ₹285 to ₹300 per share and has seen exceptionally strong demand from non-institutional and retail investors.
Tempsens Instruments operates in a specialised industrial segment covering temperature-sensing solutions, electrical heating systems and specialised cables. Its financial performance has improved significantly over the past three years, but investors also need to consider its premium valuation, rising working-capital requirements and the large offer-for-sale component.
Here is a detailed look at the Tempsens Instruments IPO date, price, allotment schedule, financials, strengths, risks and overall IPO review.

Tempsens Instruments IPO Date and Allotment Schedule
For investors primarily searching for the Tempsens Instruments IPO allotment date, the important dates are straightforward.
The issue closes on August 24, 2026, after which the basis of allotment is expected to be finalised on August 25.
Refunds for unsuccessful applicants are scheduled to begin on August 27, while shares are expected to be credited to successful applicants' demat accounts on the same day. The tentative listing date is August 28, 2026.
Because the issue has attracted very high demand, retail applicants may face a relatively low probability of receiving an allotment if the category remains heavily oversubscribed.
What Does Tempsens Instruments Do?
Tempsens Instruments is a thermal engineering and specialised cable manufacturer.
Its products include thermocouples, resistance temperature detectors, infrared pyrometers, thermal imaging systems, temperature transmitters, thermowells, fibre-optic temperature sensors and temperature calibration equipment. It also manufactures electrical heating solutions and specialised cables.
These products are used by industrial customers where accurate measurement and control of temperature are important.
The company has exposure to sectors such as metals, petrochemicals, power and other industrial applications. It also has an international footprint, with exports to more than 80 countries.
This gives Tempsens exposure to industrial capital expenditure in India as well as overseas demand.
Tempsens Instruments IPO Subscription: Why Demand Is So Strong
Investor demand has been one of the biggest talking points surrounding the issue.
By Day 2, the IPO had been subscribed approximately 21.66–21.69 times, according to available exchange-linked data. The NII category was subscribed nearly 53 times, while the retail portion was subscribed around 18.7 times. The QIB portion stood at about 3.31 times in the Day 2 data.
Demand subsequently increased further on the final day, with reports putting overall subscription around 38 times during the ongoing bidding session.
Such strong demand can reflect several factors:
The company's specialised product portfolio
Strong recent financial growth
Industrial and export exposure
Limited direct listed comparables
Strong grey-market sentiment
Expectations of listing gains
However, high subscription should not automatically be interpreted as proof that the stock is attractively valued for the long term.
Tempsens Instruments Financial Performance
The company's recent financial numbers provide an important part of the investment case.
Total income increased from ₹278.04 crore in FY24 to ₹382.47 crore in FY25 and ₹455.86 crore in FY26. Over the same period, profit after tax increased from ₹40.92 crore to ₹62.56 crore and ₹71.07 crore.
EBITDA also increased from ₹61.13 crore in FY24 to ₹97.32 crore in FY25 and ₹113.17 crore in FY26. The FY26 EBITDA margin was approximately 24.83%, while the PAT margin was about 15.59%.
The numbers show that Tempsens is not simply a high-revenue industrial company. It has maintained relatively healthy profitability while expanding its business.
However, FY26 revenue growth was slower than the previous year's growth rate, which is something investors should monitor as the company enters the public market.
What Is the Valuation of Tempsens Instruments IPO?
At the upper price band of ₹300, available offer-document calculations put the company at roughly 35.38 times post-issue earnings, with an estimated post-issue EPS of ₹8.48. The reported RoNW is around 13.55%, while RoCE stands at approximately 21.61%.
This is not a bargain valuation.
The premium valuation can be supported if Tempsens continues to grow earnings at a healthy rate and maintains its margins. But it also means investors are already paying for a meaningful portion of the company's future growth.
There is another complication: the company does not have a directly comparable listed Indian peer covering all three of its major business segments. That makes traditional peer-based valuation comparisons less straightforward.
₹555 Crore OFS: An Important IPO Detail
One of the most important details in the Tempsens Instruments IPO review is the structure of the issue.
Out of the ₹650 crore IPO, only ₹95 crore is a fresh issue, while ₹555 crore comes through an offer for sale.
In an OFS, existing shareholders sell their shares and receive the proceeds. The company itself does not receive that portion of the money.
The ₹95 crore fresh issue is intended mainly for capital expenditure and debt repayment. According to IPO research, around ₹18.13 crore is earmarked for capex related to electrical heating and specialised cable solutions, while ₹55 crore is intended for repayment or prepayment of borrowings.
For investors, this means the IPO is primarily providing an exit opportunity for existing shareholders while giving the company a smaller amount of fresh capital for expansion and balance-sheet improvement.
Key Strengths of the IPO
Specialised Industrial Products
Tempsens operates in technically specialised areas where product reliability and engineering capabilities matter. Its portfolio is broader than basic temperature sensors, covering heating solutions and specialised cables as well.
Export Opportunity
The company generates a meaningful portion of revenue outside India and sells into more than 80 countries. This gives it access to a larger addressable market.
Healthy Operating Margins
FY26 EBITDA margin of approximately 24.83% indicates relatively strong operating profitability for an industrial manufacturing business.
Low Debt-to-Equity
The reported FY26 debt-to-equity ratio was approximately 0.15, indicating a relatively modest debt burden compared with equity.
Risks Investors Should Not Ignore
The biggest concern is working capital.
Tempsens' net working-capital days increased from around 152 days in FY24 to 193 days in FY25 and 210 days in FY26.
In simple terms, more of the company's money is tied up in its operating cycle. If this trend continues, revenue growth may require increasing amounts of capital.
The company's RoNW also declined to 13.55% in FY26, compared with 22.70% in FY24.
Another risk is customer and industry concentration. More than 40% of revenue is linked to metal and petrochemical customers, according to IPO research. A slowdown in industrial capital expenditure could therefore affect demand.
Finally, the valuation leaves less room for disappointment. A premium P/E can work well when earnings growth is strong, but a slowdown in profits can lead to valuation compression.
Tempsens Instruments IPO Review: Should Investors Apply?
The answer depends on the investor's objective.
For investors looking at listing gains, the exceptionally strong subscription and current grey-market sentiment make the IPO highly interesting. However, GMP is unofficial and can change before listing, so it should not be treated as a guaranteed return.
For long-term investors, the case is more balanced.
Tempsens has a specialised business, healthy EBITDA margins, export exposure, low leverage and a history of revenue and profit growth. These are meaningful positives.
At the same time, the IPO is priced at a premium, working-capital days have risen substantially and the majority of the issue is an OFS. The company's future performance will therefore need to justify the valuation.
Rather than focusing only on the IPO-day premium, long-term investors should watch revenue growth, margins, working-capital efficiency, order inflows, export growth and return ratios after listing.
Tempsens Instruments IPO: Final Verdict
The Tempsens Instruments IPO offers investors exposure to a specialised industrial business with strong recent financial performance and international reach. The ₹285–₹300 price band and ₹650 crore issue size have attracted substantial demand, while the allotment is scheduled for August 25, 2026, followed by the expected listing on August 28.
The company has several attractive qualities, but it is not a low-risk or deeply discounted IPO. The premium valuation, rising working-capital requirement and large OFS component deserve careful consideration.
For investors who receive an allotment, the real test will begin after listing: can Tempsens maintain its growth and margins while improving capital efficiency?
That is likely to matter far more over the long term than the IPO's grey-market premium.
