Tempsens Instruments listed at ₹631.20 on August 28, 2026 — a 110.40% gain over its ₹300 issue price. The ₹650 crore IPO had closed with 184.22x overall subscription.
Tempsens is a vertically integrated manufacturer of temperature sensors, electrical heating systems and specialised cables. Temperature sensing contributes 44.59% of FY26 revenue, specialised cables 34.71%, and electrical heating 20.70%.
The August 2026 IPO combined a ₹95 crore fresh issue with a ₹555 crore promoter sale. Promoter holding moved from 80.51% to 65.67%, still a controlling stake, while heavy institutional demand signalled confidence in niche manufacturing.
Revenue from operations climbed from ₹274.81 crore in FY24 to ₹444.88 crore in FY26, a CAGR of about 27.23%. EBITDA margins held near 25%, reflecting make-to-order precision work rather than commodity volumes.
Electrical Heating Solutions grew from 3.90% of revenue in FY24 to 20.70% in FY26. It diversifies the mix away from standalone temperature sensing, which fell from 60.58% to 44.59% over the same period.
Tempsens serves over 3,800 customers across more than 80 countries. Exports earned ₹125.82 crore in FY26, about 28.5% of operating revenue, while the top 10 customers were just 18.59% of revenue.
Tempsens is the largest manufacturer of contact and non-contact temperature sensors by revenue in India. It holds roughly 10.5% of the overall temperature sensor market and 21.3% of the niche non-contact segment.
Fresh issue proceeds direct ₹55 crore toward prepaying borrowings and ₹18.13 crore toward expanding electrical heating and specialised cable capacity. Debt-to-equity was already a conservative 0.15x, so deleveraging further reduces finance costs.
Platinum, rhodium and nickel alloys expose margins to commodity swings. Ten of 15 manufacturing units sit in Udaipur, concentrating output risk. OEM-heavy revenue depends on global industrial capex, and exports bring forex volatility.
Tempsens evolved from European equipment distribution into 15 global manufacturing units with ISRO-linked heat flux sensors and elite calibration capabilities. Read the full deep dive for the complete financials, risks and segment detail.
