This page restates what Tempsens Instruments (India) Limited has filed for its initial public offering — the Red Herring Prospectus dated 14 August 2026, the price-band advertisement, and the 19 August 2026 anchor-investor allocation letter — as filed, with no added opinion. If the vocabulary is new — DRHP, price band, buckets, allotment — read how an Indian IPO actually works first.

What the company does

Tempsens Instruments (India) Limited was incorporated on 14 September 1990, originally as a private limited company, and converted to a public limited company on 6-7 August 2025. Per the RHP, the Company manufactures contact and non-contact temperature sensors, electrical heating solutions, and specialised cables, for industries including oil & gas, petrochemicals, power generation, glass, aerospace, pharmaceuticals, nuclear and defence. Citing a Frost & Sullivan report the Company itself commissioned and paid for, the RHP states that Tempsens is India’s largest manufacturer of contact and non-contact temperature sensors by revenue, with about 10.5% market share in Fiscal 2026, and one of the largest manufacturers of electrical heaters in India.

The Company’s Registered Office is at Vadodara, Gujarat (TF-304, Florence Classic, 10 Ashapuri Society, Akota, Vadodara 390020); its Corporate Office, where most manufacturing is based, is at Udaipur, Rajasthan (Road No. 5, Industrial Area Madri, Udaipur 313003). The Company, its subsidiaries and its joint ventures together operate 15 manufacturing units worldwide — ten in Udaipur, India, and five overseas: Tempsens Gulf LLC (UAE), Tempsens Korea Co. Ltd. (South Korea, a joint venture), PT. Tempsens Asia Jaya (Indonesia, a joint venture), Tempsens Instruments GmbH (Germany), and Tempsens Polska Sp. z o.o. (Poland). The Promoters are Virendra Prakash Rathi (Chairman & Executive Director), Vinay Rathi (Managing Director) and Pratap Singh Talesara.

What the money is for

The Fresh Issue — up to Rs 950.00 million (~Rs 95.00 Cr) — is proceeds to the Company, for the objects below. The Offer for Sale is a fixed count of up to 1,85,00,000 Equity Shares by five selling shareholders; that money goes to the selling shareholders, not to the Company.

Object of the fresh issue Amount, as filed
Capital expenditure — electrical heating solutions and specialised cable verticals Rs 181.34 million
Prepayment / scheduled repayment of outstanding borrowings Rs 550.00 million
General corporate purposes Balance of Net Proceeds, not exceeding 25% of Gross Proceeds

Acquisition costs are per the RHP, certified by Bansi Lal Shah & Co., Chartered Accountants, in a certificate dated 14 August 2026.

What the RHP flags as risks

The RHP lists these among the Company’s own risk factors, paraphrased here without added commentary:

  • Revenue is concentrated in the Projects/OEM business line. Projects/OEM accounted for 67.55% / 69.16% / 63.99% of revenue from operations (excluding scrap sale and export incentive) in FY2026 / FY2025 / FY2024, with the remainder from the MRO (replacement) business; adverse changes in either category could materially affect the business.
  • Demand is exposed to a small set of end-user industries. Metal and petrochemical industries together contributed 41.13% / 42.90% / 41.52% of revenue (ex scrap sale and export incentive) in FY2026 / FY2025 / FY2024; negative developments in these sectors could materially affect results.
  • Raw-material supply risk is flagged. Significant volatility, increases, fluctuations, shortages or delays in the supply of primary raw materials may adversely affect the business.
  • Supplier concentration, no definitive agreements. The Company depends on a limited group of suppliers for raw materials and has no definitive supply agreements with them.
  • Manufacturing is concentrated at one location. Ten of the group’s 15 manufacturing units (Company, subsidiaries and joint ventures combined) are at Udaipur, Rajasthan; operating or location-specific disruptions at domestic or international units could adversely affect the business.
  • Reliance on subsidiaries and joint ventures for international market entry. The RHP states that JV arrangements “involve shared ownership and decision-making,” and that differences in strategic priorities between the Company and its JV partners may lead to disagreements or delays.

The numbers as filed

Item As filed
Face value Rs 4 per Equity Share
Price band Rs 285 (floor) – Rs 300 (cap) per share
Fresh issue Up to Rs 950.00 million (~Rs 95.00 Cr)
Offer for Sale Up to 1,85,00,000 Equity Shares
Aggregate issue size Up to ~Rs 650 Cr (as reported)
Anchor Investor Allocation Price Rs 300 per share (cap price)
Lot size 50 Equity Shares (as reported)
Minimum retail investment Rs 15,000 for 1 lot at the cap price (as reported)

The RHP itself leaves the Price Band and the total Offer value as blanks, to be filled in once the Offer Price is fixed. The Rs 300 cap is corroborated by the Anchor Investor Allocation Price stated in the Company’s 19 August 2026 letter; the Rs 285 floor and the 50-share lot size are as reported by IPO trackers, not stated as numbers in the RHP itself. The ~Rs 650 Cr aggregate is also as reported, and is arithmetically consistent with the RHP’s fixed components at the cap price: Rs 95 Cr fresh issue plus 1,85,00,000 shares of Offer for Sale at Rs 300 equals Rs 555 Cr, for a total of Rs 650 Cr.

Restated Consolidated financials, as filed in the RHP:

Particulars (Rs million) FY2026 FY2025 FY2024
Revenue from operations 4,448.78 3,785.26 2,748.10
Total income 4,558.55 3,824.68 2,780.42
Profit for the year (PAT) 710.67 625.55 409.19

In Rs crore (own conversion, 1 crore = 10 million): total income ~455.86 / 382.47 / 278.04; PAT ~71.07 / 62.56 / 40.92, for FY2026 / FY2025 / FY2024 respectively.

Who can actually sell on listing day

The RHP’s lock-in schedule, and the anchor allotment already finalised, determine who is free to sell Tempsens shares on the day the stock lists.

Who Locked for, per this RHP
Minimum Promoters’ Contribution (20% of post-Offer capital) 18 months from the date of Allotment
Promoters’ holding above the 20% minimum 6 months from the date of Allotment
All other pre-Offer shareholders (non-promoter) 6 months from the date of Allotment, with carve-outs for OFS-transferred shares, ESOP-2025 shares issued on exercise, and VCF/AIF (Category I or II)/FVCI holdings, which instead lock 6 months from their own date of purchase
Anchor Investors 50% of shares allotted locked 90 days from Allotment; the remaining 50% locked 30 days from Allotment
Step Shares % of post-issue capital
Fresh issue 31,66,666 3.78%
Offer for Sale 1,85,00,000 22.07%
Total offer 2,16,66,666 25.85%
Less: anchor allotment, locked 30/90 days −64,84,999 −7.74%
= Sellable on listing day 1,51,81,667 18.11%
Locked or not offered — the rest of the register 6,86,51,024 81.89%
Post-issue capital 8,38,32,691 100.00%

Anchor allocation was finalised on 19 August 2026 at Rs 300 per share — the cap price, comprising Rs 4 face value plus Rs 296 premium — to 29 anchor investors, per the Company’s letter to BSE and NSE dated the same day, itself citing the RHP dated 14 August 2026 and the price-band advertisement dated 14 August 2026 (published 17 August 2026).

A lock-in is not a forecast of anything — it is a restriction on selling; it says who may trade, not what the price will do.

This table reflects the RHP dated 14 August 2026 and the anchor-allocation letter dated 19 August 2026, as of 23 August 2026.

Figures move through the issue lifecycle — check the filed documents before acting on any of them. Grey-market premium is an unofficial, unregulated price with no exchange record, and is not referenced here as information.

Common questions

How does IPO allotment work?

Applications are matched against the minimum lot size within each investor category (retail, HNI, QIB). In the retail category every applicant is first considered for one minimum lot: when the retail portion has enough shares to give every retail applicant one lot, everyone gets at least one and the surplus goes proportionately to those who bid more. Only when there aren't enough shares for one lot each is a computerised draw of lots used to pick who gets that single lot — and then each successful applicant gets exactly one lot, however many they bid for. It is never first-come-first-served, so applying early doesn't improve the odds.

What does the anchor investor lock-in mean?

Anchor investors (institutions allotted shares a day before the issue opens) are locked in and can't sell for a fixed period — and the clock runs from the date of Allotment, not from listing. Under the SEBI ICDR Regulations, 50% of the anchor shares are locked for 90 days from Allotment and the remaining 50% for 30 days from Allotment. It restricts anchors only; it says nothing about how retail-held shares will trade.

When do I get my money back if I'm not allotted?

Under ASBA, your bank only blocks the funds in your account — it's never debited until allotment. If you get no shares (or only a partial allotment), the block is released without any separate refund step: SEBI requires your bank (the SCSB) to complete the unblock by the close of banking hours on the working day after the basis of allotment is finalised — under the T+3 timeline, the day before the shares list. If it takes longer than that, SEBI's compensation policy provides ₹100 per day or 15% per annum of the application amount, whichever is higher — but it is complaint-triggered, so you have to raise it with your bank or the issue's lead manager to claim it.

What is ASBA / the UPI mandate?

ASBA (Application Supported by Blocked Amount) blocks the bid amount in your bank account instead of debiting it upfront. Retail investors bidding through UPI approve a mandate request in their UPI app, which blocks the funds — the money leaves your account only if shares are actually allotted.
