The much-awaited Tenneco Clean Air IPO allotment is expected to be finalised today, November 17, after the auto-components manufacturer concluded its highly subscribed public issue last week. With strong investor demand and an impressive rise in the grey market premium (GMP), market participants are closely watching the allotment outcome as the listing day approaches.
Tenneco Clean Air IPO: Strong Investor Response
Tenneco Clean Air India Ltd, a subsidiary of US-based Tenneco Inc., opened its initial public offering for subscription between November 12 and November 14. The IPO drew robust interest from all categories of investors, reinforcing the growing market appetite for high-quality auto technology companies.
The company is now set to finalise the basis of allotment today, November 17. Following this, equity shares are expected to be credited to the demat accounts of successful bidders by November 18. Unsuccessful applicants will receive refunds on the same day.
The stock is scheduled to make its debut on both the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE) on November 19, making the issue one of the key listings of the month.
Tenneco Clean Air IPO GMP Surges Ahead of Listing
The grey market continues to reflect strong optimism about Tenneco Clean Air’s listing prospects. According to market observers, the Tenneco Clean Air IPO GMP has surged to ₹125 per share, suggesting a robust premium over the issue price of ₹397.
If the current GMP trend sustains, the stock may list around ₹522 per share, translating into an approximate 31.5% premium. While the GMP is not an official indicator of listing price, it often reflects market sentiment and short-term expectations of investors.
Analysts say the strong grey market trend highlights confidence in the company’s financial profile, its global parentage, and its focus on clean air and emissions technology — a space gaining increasing relevance amidst tightening environmental regulations worldwide.

Why the IPO Attracted Strong Interest
Market experts say several factors contributed to the positive sentiment surrounding the Tenneco Clean Air IPO:
1. Established Global Parent Company
Tenneco Inc., headquartered in the United States, is a leading name in the automotive components industry. Its strong research, manufacturing capabilities, and long-standing customer relationships add credibility to its Indian subsidiary.
2. Growing Focus on Clean Air Technologies
As India tightens emission norms and automakers adopt advanced technologies, the demand for clean air solutions is rising. Tenneco Clean Air India operates in this high-growth domain.
3. Healthy Financial Performance
The company has reported stable revenue, consistent order inflows, and strong partnerships with major automobile manufacturers, all of which contributed to investor confidence.
4. Attractive Valuation
Despite the competitive landscape, analysts believe the IPO was reasonably priced, driving increased investor participation during the subscription period.
Market Expectations Ahead of Listing
With the GMP rising and subscription numbers strong, analysts expect a positive listing on November 19. However, they caution that post-listing performance will depend on broader market trends, quarterly results, and the company’s execution capabilities in a rapidly transforming automobile ecosystem.
