Tenneco Clean Air IPO Allotment Status, GMP Live: Deven Choksey Research take on this IPO

“The IPO is considered competitively priced as it is valued at a Price-to-Earnings (P/E) multiple of approximately 29x based on FY25 earnings. This represents a significant discount compared to its auto ancillary peers, such as Bosch Ltd. and Uno Minda, which are trading at an average P/E of around 48-50x. The company’s primary moat is its dominant market leadership, holding over 50% share in key segments like clean air solutions for commercial trucks and shock absorbers for passenger vehicles. This position is secured by high switching costs from deep OEM integration (like Maruti Suzuki and Tata Motors) and access to its global parent’s advanced, proprietary technology required to meet strict emission norms,” said Deven Choksey Research in its IPO note.

Tenneco Clean Air IPO Allotment Status, GMP Live: Brokerage take on this IPO

“At the upper price band of Rs 397, TCAIL is valued at 29x FY25 P/E, which appears reasonable relative to peers. Supported by strong parentage, market leadership in clean-air and ride performance systems, established OEM partnerships, robust financials, and healthy return ratios, the company is well-positioned to capitalize on structural tailwinds in India’s auto sector, including premiumization and tightening emission norms. Hence, we recommend a ‘Subscribe’ rating for the long term,” said Geojit in its IPO note.
