Tenneco Clean Air IPO Details
Tenneco Clean Air made an impressive debut on the BSE and NSE on November 19, 2025, following the completion of its public issue. The IPO was open for bidding from November 12 to November 14, with allotments finalised on November 17. The issue, valued at 3,600 crore, was structured entirely as an offer for sale (OFS) comprising 9.07 crore shares. The price band was set between 378 and 397 per share, while the lot size for retail investors was fixed at 37 shares, translating into a minimum application amount of 14,689.
JM Financial Ltd. acted as the book-running lead manager to the issue, and MUFG Intime India Pvt. Ltd. served as the registrar. Since the IPO consisted solely of an offer for sale, the entire proceeds will go to the selling shareholders rather than the company.
The offering received robust investor interest, particularly from qualified institutional buyers (QIBs) and non-institutional investors, resulting in an overall subscription of 61.79 times on the final day. Although demand remained muted on the opening day, momentum accelerated sharply over the next two sessions, driving total bids to 392 crore shares against the 6.34 crore shares on offer.
QIBs dominated the response, with their category subscribed 174.78 times, while non-institutional buyers booked their portion 42 times. Retail investors showed comparatively moderate interest, leading to a subscription level of 5.37 times in their segment, based on exchange data.
Ahead of the IPO launch, the company had successfully mobilised 1,080 crore from anchor investors on November 11.
