Tenneco Clean Air India shares soar 30% over issue price of ₹397 after debut

The stock opened at ₹505 on the NSE, reflecting a 27.2% premium over its issue price of ₹397.

Tenneco Clean Air India made a steady debut on the bourses today, listing at a modest premium.

The stock opened at ₹505 on the National Stock Exchange (NSE), reflecting a 27.2 per cent premium over its issue price of ₹397. On the Bombay Stock Exchange (BSE), shares debuted at 25.4 per cent premium at ₹498.

Post-listing, the stock scaled 30 per cent from its offer price to a high of ₹517. At 10.27 am, it traded at ₹488.55 on the NSE and at ₹495.55 on the BSE.

Market analysts had anticipated a positive but measured listing, citing the company’s industry positioning, demand in the IPO, and the fully offer-for-sale structure. The initial trade today reflected those expectations, with the stock commanding a healthy yet controlled premium as investors assess long-term growth prospects amid an expanding clean-mobility components market.

According to Shivani Nyati, Head of Wealth at Swastika Investmart Ltd, the strong opening was aided by investor confidence in the company’s global backing, advanced clean-air and emission-control technology and long-standing relationships with major automobile OEMs. Also, the diversified product range and alignment with tightening emission norms has further strengthened sentiment.

However, caution remains due to the auto sector’s cyclicality, dependence on OEM volumes, and raw-material–linked margin pressures, Nyati emphasised, and advised allottees may consider booking partial gains and holding the rest with a stop-loss near ₹480.

The listing comes on the heels of ₹3,600 crore initial public offering. The IPO of the company, part of the US-based Tenneco Group, was subscribed nearly 59 times on the final day, driven primarily by strong demand from institutional investors.

Ahead of the issue, the company mobilised ₹1,080 crore from anchor investors, boosting confidence in the offering.

The IPO consisted entirely of an offer-for-sale by promoter entity Tenneco Mauritius Holdings Ltd, with no fresh equity issuance. According to regulatory filings, the company increased its issue size to ₹3,600 crore from the originally planned ₹3,000 crore. The promoters include Tenneco Mauritius Holdings Ltd, Tenneco (Mauritius) Ltd, Federal-Mogul Investments BV, Federal-Mogul Pty Ltd, and Tenneco LLC.

Tenneco Clean Air India is engaged in the manufacturing and supply of highly engineered, technology-intensive clean air, powertrain, and suspension solutions for domestic original equipment manufacturers as well as export markets.
