IPO Objectives
- The IPO is entirely an Offer for Sale (OFS). The company will not receive any proceeds. The objective is to achieve the benefits of listing and provide liquidity to the selling shareholder (Tenneco Inc.).
Strengths
- The company is a leading supplier benefiting from Tenneco Inc.'s global technology and R&D network.
- It offers a wide range of products across clean air and advanced ride technologies, designed to meet changing emission standards (BS VI).
- The business has an extensive manufacturing footprint with 12 modern plants across seven states, ensuring proximity to major OEMs.
- It shows strong financial growth, with Profit After Tax (PAT) increasing by 33% and high EBITDA margin (16.53%) in FY25.
- The company operates in a high-growth and high-entry-barrier industry driven by stringent government mandates (BS VI, CAFE norms).
Weaknesses
- The IPO is a Pure Offer for Sale (OFS), meaning the company will receive no fresh proceeds for expansion or debt repayment.
- The business is vulnerable to automotive industry cycles and any slowdown in vehicle production or sales in India.
- It faces exposure to volatility in raw material prices (steel, aluminum, precious metals for catalysts), which can impact profitability.
- The company is highly dependent on a limited number of major OEMs for a substantial portion of its revenue.
- There is a risk of revenue volatility due to a significant 11% decrease in total income between FY24 and FY25.
