Udaipur rarely makes headlines in the world of capital markets. But that's about to change. Tempsens Instruments (India) Limited is a thermal engineering and specialised cable company quietly built over decades in Rajasthan. It is heading to the public markets, with its IPO opening on August 20, 2026, and closing on August 24, 2026. The total issue size is up to ₹650 crore and the company is seeking to raise ₹95 crore via a fresh issue, alongside an Offer for Sale of up to ₹555 crore by existing shareholders. It will list on both BSE and NSE, with NSE as the designated stock exchange.
Tempsens Instruments (India) Limited is a thermal engineering and specialised cable manufacturer headquartered in Udaipur, Rajasthan. It designs and manufactures customised temperature sensing solutions, electrical heating solutions, and specialised cables; all made-to-order, addressing complex thermal management challenges across industries. The company serves 3,800+ customers across metals, oil & gas, power, automotive, glass, chemicals, defence, and renewables.
Its product portfolio has expanded from 7 categories in FY20 to 13 categories across 3 verticals in FY26, covering technologies like thermocouples, resistance temperature detector (RTD)s, infrared pyrometers, mineral-insulated cables, and industrial furnaces.
The financial story here is straightforward and compelling. Revenue has grown from ₹274.8 crore in FY24 to ₹444.9 crore in FY26; a 27.23% CAGR. EBITDA has expanded even faster at 36.07% CAGR, with margins holding comfortably in the 24–25% range. PAT has compounded at 31.79% over the same period.
| Metric | FY24 | FY25 | FY26 |
|---|---|---|---|
| Revenue from Operations (₹ Cr) | 274.81 | 378.52 | 444.87 |
| EBITDA Margin | 21.98% | 25.45% | 24.83% |
| PAT (₹ Cr) | 40.91 | 62.55 | 71.06 |
| ROCE | 22.82% | 23.08% | 21.61% |
| Debt-to-Equity | 0.15x | 0.16x | 0.15x |
The balance sheet is lean. A debt-to-equity ratio of 0.15x is a rarity in a manufacturing business of this scale. ROCE has stayed consistently above 21% across all three years. A sign that capital is being deployed efficiently, not just accumulated.
The standout story within the financials is electrical heating solutions- the newest vertical, which grew from ₹10.6 crore in FY24 to ₹91.3 crore in FY26. That's nearly 9x growth in two years, largely driven by the amalgamation of Marathon Heater into the company. It now contributes over 20% of total revenue and is still running at sub-55% capacity utilisation; meaning there's significant room to scale without proportionate capex.
One of the more underappreciated aspects of Tempsens is its international footprint. The company operates 15 manufacturing units worldwide; 10 in India and 5 internationally- across Germany, UAE, Indonesia, South Korea, and Poland; giving it local market access in key industrial economies. International revenue has grown from 21.49% of total revenue in FY24 to 28.52% in FY26, with Africa & MENA (10.01%), Europe (9.74%), and Asia Pacific (6.68%) as the key export corridors.
Every single Indian manufacturing unit is located in Udaipur, Rajasthan- spread across industrial estates like Madri Industrial Area, Mewar Industrial Area, and Gudli Industrial Estate. This concentration is both a strength (tight operational control, shared infrastructure, proximity of teams) and a structural risk (a single geographic disruption could impact the entire domestic production base).
What makes the business model particularly interesting is its low customer concentration. The top 10 customers contribute just 18.59% of FY26 revenue, spread across 3,800+ clients. The average relationship with its top 20 customers spans 10 years; a strong indicator of stickiness and trust in a space where precision and reliability are non-negotiable.
The ₹95 crore fresh issue has two primary uses: ₹55 crore goes toward debt repayment, and ₹18.13 crore is earmarked for capital expenditure- specifically for new machinery in the electrical heating and specialised cable units. The remainder is for general corporate purposes.
The debt repayment component is a positive signal; it reduces interest burden and improves future cash flows. The capex is targeted at Units IV and VI in Udaipur, where specialised cable capacity is already running near full (90.57% utilisation) and electrical heating has room to grow.
The OFS portion- 1.85 crore shares; is being sold by Chandra Prakash Talesara, Amit Talesara, Puneet Talesara, Ankit Talesara and Nirmal Kumar Pande. The Rathi family promoters (Vinay Rathi and Virendra Prakash Rathi) are not selling any shares, which is a meaningful signal of conviction.
Tempsens is a classic Indian promoter-led business, but one that has evolved with institutional discipline. The promoters include Virendra Prakash Rathi, Vinay Rathi and Pratap Singh Talesara. Virendra Prakash Rathi (77), the Chairman, founded and built the company. His son Vinay Rathi serves as Managing Director and holds a 30% stake- the largest single block in the company. The third generation, Aryan Rathi, leads global sales.
The lead managers are ICICI Securities and JM Financial, with KFin Technologies as the registrar.
No IPO analysis is complete without an honest look at the risks. Tempsens has several worth flagging:
Geographic concentration is the most structural concern. A significant number of manufacturing units are located in Udaipur, Rajasthan. A single disruption- flood, labour unrest, or regulatory action; could have a huge impact on the production base.
Unhedged forex exposure is a live risk. With nearly 29% of revenue coming from international markets, the company has explicitly stated it does not hedge its foreign currency exposures. A sharp INR appreciation could compress export margins meaningfully.
Auditor change is worth noting. Walker Chandiok & Co LLP (a Big 4 affiliate) replaced the previous joint auditors- Bansi Lal Shah & Co. in September 2025, just ahead of the IPO. The outgoing auditors had flagged "other matters" in their FY25 consolidated audit report. While not necessarily alarming, a pre-IPO auditor change always warrants scrutiny.
No listed peers makes valuation a challenge. The company has acknowledged in its RHP that there are no exact comparable listed peers in India across its combined product portfolio. Investors will need to benchmark it against partial comparables in cables, sensors, or industrial equipment; none of which are a perfect fit.
Projects/OEM dependency (67.55% of revenue) means the business is partially tied to industrial capex cycles. During slowdowns, order flows can dry up quickly. The maintenance, repair, and operations (MRO) component (32.45%) provides a buffer, but it's not enough to fully insulate the business.
| Risk Factor | Severity | Nature |
|---|---|---|
| Unhedged forex exposure | High | Financial |
| Auditor change pre-IPO | Medium | Governance |
| No listed comparable peers | Medium | Valuation |
| Projects/OEM revenue dependency | Medium | Business Model |
| Contingent liabilities (₹1.73 crore) | Low | Legal/Tax |
Tempsens Instruments is not a flashy consumer brand or a high-growth tech story. It is a precision industrial manufacturer with a 3,800-customer base, a 10-year average client relationship, expanding global operations, and a balance sheet that most manufacturing companies would envy.
The growth numbers are genuine- not inflated by one-off events. The promoters are not exiting. The fresh issue proceeds are going toward debt reduction and capacity expansion, not promoter payouts. And the business operates in a segment- thermal engineering and specialised cables; that is structurally tied to India's ongoing industrialisation, infrastructure buildout, and defence modernisation.
The risks are real but manageable. The geographic concentration and forex exposure are the two that deserve the most attention. For investors comfortable with a mid-sized industrial compounder story, Tempsens offers a compelling, if under-the-radar, opportunity.
