Tenneco Clean Air Shares Debut Over 27% Higher; Investors See Strong Per-Lot Profit
Tenneco Clean Air India Limited received an impressive market response, opened near ₹ 505 on the NSE, and delivered substantial gains to the retail investors straight away from the first trade

Strong Market Debut and Listing Price
On the NSE, the shares of Tenneco Clean Air India Limited began trade at ₹ 505, a sharp jump of 27.20% above its issue price of ₹ 397. The stock also opened firmly on the BSE at ₹498 apiece, representing a healthy 25.44% listing premium. This robust performance at the listing indicates solid investor confidence in the business prospects and sector outlook of the company.
Investor Profits Per Lot
With every IPO lot comprising 37 shares, investors got a handsome return on the first day itself. Those who sold their allotted lot at the listing price gained ₹18,685 approximately per lot. A high listing gain indicates the good demand the company witnessed during the subscription period amid positive market sentiments for the offering.
IPO Composition and Subscription Numbers
The IPO of the company was thus a complete OFS, with the promoter Tenneco Mauritius Holdings Ltd offloading 9.07 crore shares, garnering close to ₹3,600 crore. Since the issue did not have any fresh shares, the company itself did not mobilize fresh capital. Besides, the IPO attracted overwhelming response, with an overall subscription of 58.83 times, while the QIBs bid an extraordinary 166.42 times.
Company Background
Tenneco Clean Air India manufactures a range of clean-air, powertrain, and suspension components, including catalytic converters, exhaust after-treatment units, mufflers, shock absorbers, and struts. The organisation is supported by a strong promoter group comprising Tenneco (Mauritius) Ltd, Tenneco LLC, and Federal-Mogul entities, enhancing its global credibility and operational footprint.
