Tenneco Clean Air To Launch IPO On Nov 12

A major auto-ancillary player is gearing up for public listing. Tenneco Clean Air India Ltd. is launching its IPO (Initial Public Offering) on November 12. Tenneco is a subsidiary of the US-based Tenneco Group. The issue is a 100% OFS (Offer for Sale) by its promoter, Tenneco Mauritius Holdings Ltd. Additionally, the offer has been noticeably increased in size to ₹3,600 crore from the initially planned ₹3,000 crore. Tenneco’s IPO subscription will be open for public bidding until November 14. The anchor book would be opened for a single day on November 11.

This promoter exit has come after a strong financial performance. In the 2025 fiscal year, the company’s profit soared 32.5%, reaching ₹552 crore. However, its revenue dipped 10.6%. A significant expansion in EBITDA margins substantially drove the company’s profits. This profit momentum has also continued in the June 2025 quarter, where there was a profit of ₹167.8 crore. Therefore, it can be said that the promoter has already tested the waters. Additionally, last week, Tenneco Mauritius sold a 2.75% stake for ₹440 crore to 14 investors, setting a valuation of over ₹16,000 crore (approximately ₹397/share). These included investors such as 360 ONE

The IPO offer has been reserved:

• 50% for qualified institutional buyers (QIBs).
  
• 15% for non-institutional investors (NIIs).
  
• 35% for retail investors.
  

The final listing on the BSE and NSE is expected on November 19. With the company itself receiving no growth capital from this public offering, a key question for investors is: what exactly are they buying into?

What is the Story of a 100% Exit?

It is important to understand what a pure Offer for Sale signifies in this listing. A pure OFS would mean that not a single rupee from the public issue will go into the company's bank account. Rather, the entire sum raised will go directly to the promoter which is its US-based parent. The promoter is cashing out a part of its stake. Thus, this is not a growth-funding IPO for a startup. But it is a "liquidity event" for the parent to unlock the value of its highly successful Indian subsidiary.

So, why should a retail investor be interested? Investors can focus on buying into a mature, stable, and highly profitable business. The company is not a startup that would need public money to survive. Instead, it is a cash-generating machine.

The prominent domestic mutual funds have lined up to buy a stake from the promoter just last week in the pre-IPO placement. This can be perceived as strong institutional confidence in the implied valuation. This IPO is simply the first time that the general public has been given the chance to own a piece of this established market leader. However, without fresh funds for the company, what is the core business that investors are betting on?

How Strong Is Tenneco’s Business?

Tenneco's value lies in three main aspects:

• Its deep integration within the Indian automotive supply chain
  
• Its high-technology products.
  
• Its specialisation in critical, engineered solutions
  

This is not a company that makes easily replicable commodity parts. It instead is an experienced provider of solutions that are essential for modern vehicles to function.

The company's competitive advantage, also known as "moat," is built on two broad pillars.

1. Market Dominance - The company has claimed to be the largest supplier of clean air solutions (such as emissions-control systems) to commercial truck OEMs (original equipment manufacturers) in India and the largest supplier of shock absorbers and struts to passenger vehicle OEMs.

2. A "Who's Who" Client List - Tenneco Clean Air’s customer base is not fragmented or unstable. The company has served nearly all major auto manufacturers in the country. This includes major players like Ashok Leyland, Bajaj Auto, Cummins, Hyundai, Mahindra & Mahindra, Maruti Suzuki India, Tata Motors, and Toyota Kirloskar Motor. This blue-chip client list has resulted in a reliable revenue stream and is environmentally compliant.

The IPO Signal

The company has demonstrated exceptional operational efficiency and a strong pricing power. Tenneco’s profits have considerably expanded even with a decline in revenue. This suggests that management has a powerful grip on its expenses, particularly raw material costs, and that its products are not easily substituted. Thus, the final question for investors is whether the valuation set by the promoter has fully captured this strength, or if it has left enough on the table for public investors?
