Tenneco Clean Air IPO Day 1: Subscribed 18%, GMP ₹78, Experts Take — What’s Next for Investors?

Tenneco Clean Air IPO Day 1: The Tenneco Clean Air India IPO opened for subscription on 12th November 2025, and Tenneco Clean Air IPO Day 1 witnessed a cautious yet steady start. The ₹3,600-crore public issue, entirely an Offer for Sale (OFS), saw interest gradually picking up from retail and non-institutional investors through the trading day.

While institutional demand remained muted on the Tenneco Clean Air IPO Day 1, grey market indicators hinted at robust investor sentiment for the company’s debut.

How much subscription did Tenneco Clean Air IPO Day 1 receive?

Note: These are provisional Tenneco Clean Air IPO Day 1 figures and may vary by the end of bidding hours.

What is Tenneco Clean Air IPO GMP Today?

The Tenneco Clean Air IPO GMP today stood in the range of ₹60 to ₹75 on Day 1. This suggests a potential listing premium of around 15–18% over the upper price band.

However, it’s important to note that GMP is only an informal sentiment indicator and not a reliable measure of listing performance. Market experts caution that grey market trends are volatile and may fluctuate sharply depending on demand in the retail and institutional categories.

Should investors rely on the GMP signal?

Not entirely. While a positive GMP often reflects strong market sentiment, investors should look deeper into the company’s fundamentals. Tenneco Clean Air’s strong operational performance, established client base in the global auto OEM ecosystem, and steady margins make it an attractive play for long-term investors.

However, since this IPO is a pure OFS, the proceeds will not go directly to the company. Hence, traders seeking short-term gains should balance their expectations and focus on allocation strategy rather than GMP buzz.

What are experts saying about the Tenneco Clean Air IPO?

Market experts have expressed a balanced view on this IPO. Analysts note that while the company operates in a structurally growing emission control technology segment, valuations appear on the higher side given that it’s an OFS.

Experts believe that Tenneco Clean Air’s brand credibility, global OEM partnerships, and technical expertise make it suitable for long-term investors, but short-term traders should remain cautious due to possible listing-day volatility.

Analyst View: “Strong fundamentals, clean balance sheet, and growing demand in emission control systems make this an interesting long-term bet. However, given the OFS structure, near-term listing gains may depend heavily on institutional participation on Day 2 and Day 3.”

Investor Tip

If you’re applying as a retail investor, ensure your UPI ID is active, apply before 2 PM on the closing day, and prefer bidding at the upper price band for a higher chance of allotment. Avoid overexposure in OFS-based IPOs if your goal is short-term profit.

Conclusion

The Tenneco Clean Air IPO Day 1 response indicates cautious optimism among investors. Retail participation is picking up steadily, and a healthy grey market premium adds to the positive sentiment. However, final demand from institutional investors over the next two days will ultimately decide the IPO’s success and potential listing performance.
