Tenneco Clean Air India Share Price LIVE: Stock Lists at 27% Premium, Strong Market Debut

Tenneco Clean Air India made an impressive debut on the Indian stock market on Wednesday, November 19, listing at a 27% premium over its IPO issue price. The company’s shares opened at ₹505 on the NSE and ₹498 on the BSE, offering solid listing gains to IPO allottees.

Despite the strong start, the stock witnessed slight volatility soon after opening. On the BSE, Tenneco Clean Air India shares slipped 1.41% to ₹491, while on the NSE, the stock was down over 2% at ₹493.80 in early trade.

Analysts Anticipated Strong Premium

Market experts had earlier forecast a robust listing, citing the company’s improving financial performance. Tenneco Clean Air India’s net profit rose from ₹381 crore in FY23 to ₹553 crore in FY25, with margins improving from 7.9% to 11.3%. The momentum continued into Q1 FY26 as well.

However, analysts noted that with a P/E of ~24x on annualised FY26 earnings, the issue appeared fairly valued, offering limited room for additional listing gains. Strong fundamentals—such as its global parentage, consistent dividend payouts, and an RoCE above 50% in FY25—continue to support long-term investor confidence.

Grey Market Premium (GMP) Signals

Ahead of its listing, the Tenneco Clean Air India IPO enjoyed a strong grey market premium (GMP) of ₹103, indicating a potential listing price near ₹500, which aligns closely with the actual debut.

IPO Debut Marks Key Milestone

The stock’s listing on November 19 has drawn significant investor interest, marking a key milestone for the company as it enters the public markets with strong financials and steady growth prospects.
