Tenneco Clean Air India made a notable debut in the stock market today, listing at a modest premium. The stock opened at ₹505 on the National Stock Exchange (NSE), which represents a 27.2% premium compared to its issue price of ₹397. On the Bombay Stock Exchange (BSE), shares started trading at ₹498, reflecting a 25.4% premium.
Following its listing, the stock rose by 30% from the offer price, reaching a high of ₹517. However, by 10:27 AM, it was trading at ₹488.55 on the NSE and ₹495.55 on the BSE.
Market analysts approached the stock’s debut with caution, expecting a positive but measured response due to the company’s positioned status in the industry, demand for the IPO, and the fully offer-for-sale structure. This initial trading hinted at healthy investor interest as they evaluate long-term growth potential against the backdrop of an expanding clean-mobility component market.
Shivani Nyati, Head of Wealth at Swastika Investmart Ltd, noted that the strong opening could be attributed to investor confidence in the company’s global backing, its advanced clean-air and emission-control technologies, as well as enduring partnerships with major automobile original equipment manufacturers (OEMs). Additionally, the company’s diversified product range and alignment with tightening emission standards have further boosted investor sentiment.
Despite this optimism, Nyati cautioned about the auto sector’s cyclicality, dependence on OEM volumes, and raw-material-related margin pressures. She advised investors to consider booking partial gains while keeping stop-loss levels near ₹480.
This listing follows a successful initial public offering (IPO) that raised ₹3,600 crore. The IPO was notably oversubscribed nearly 59 times on its final day, thanks in large part to strong institutional demand. Ahead of the offering, the company secured ₹1,080 crore from anchor investors, which bolstered confidence in the IPO.
The entire IPO consisted of an offer-for-sale by promoter entity Tenneco Mauritius Holdings Ltd, with no new equity issued. Regulatory filings indicated that the company increased its issue size to ₹3,600 crore from an initially intended ₹3,000 crore. Promoters include Tenneco Mauritius Holdings Ltd, Tenneco (Mauritius) Ltd, Federal-Mogul Investments BV, Federal-Mogul Pty Ltd, and Tenneco LLC.
Tenneco Clean Air India specializes in the manufacturing and supply of advanced, technology-intensive solutions focused on clean air, powertrains, and suspension for both domestic OEMs and international export markets.
