Valuation & Summary View
At the upper price band of ₹397 and latest EPS of ₹13.68, the IPO is valued at a price-to-earnings (P/E) multiple of approximately 29x. For specialized auto-component manufacturers in India, such valuations are broadly in line with sector peers.
The company also benefits from robust EBITDA margins (around 16.7% in the latest year), aided by lower input costs and operating efficiencies. With emission norms tightening under Bharat Stage VI and beyond, Tenneco Clean Air India Ltd is well-placed to benefit from sustained demand for clean air and emission-control products.
Key Positives
- Strong ROE and ROA with improving profit margins.
- Leadership position in clean air products with an estimated 57% market share.
- Diversified product basket across clean air, powertrain solutions and advanced ride technologies.
- Twelve manufacturing facilities and a domestic supply chain supporting localisation.
- Subsidiary of a global parent, which can command a valuation premium.
Investors should look at Tenneco Clean Air India Ltd as a play on stricter emission norms and technology-driven evolution in the Indian auto sector. Post-listing performance will depend on how the company manages growth, margins and capital allocation in a competitive environment.
