•The Tenneco Clean Air India IPO, valued at Rs 3,600 crore, has entered its third and final day of bidding in India, having achieved an overall subscription of 2.93 times by the end of Day 2. The IPO is also experiencing robust interest in the grey market, with a premium of approximately 19%, suggesting a potential listing price of Rs 473 against an issue price of Rs 397.
Tenneco Clean Air India is currently undertaking an Initial Public Offering (IPO) valued at Rs 3,600 crore. This public offering is structured as a pure Offer-for-Sale (OFS), meaning the proceeds from the sale of shares go to selling shareholders rather than into the company's operations. The price band for the shares has been established between Rs 378 and Rs 397 per share. Upon conclusion, the company's shares are scheduled for listing on both the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE) on November 19.
The IPO has demonstrated significant market demand, achieving an overall subscription of 2.93 times by the close of bidding on Day 2 in the Indian market. Notably, Non-Institutional Investors (NIIs) displayed substantial interest, oversubscribing their allocated portion by 7.18 times. Qualified Institutional Buyers (QIBs) also showed robust participation, subscribing 2.34 times, while Retail Individual Investors (RIIs) subscribed 1.44 times. Adding to the positive sentiment, there is robust interest in the grey market, with a premium of Rs 76, which translates to approximately 19% over the issue price.

The IPO's upper issue price is set at Rs 397 per share, within a broader price band of Rs 378-397. The current Grey Market Premium (GMP) of Rs 76 indicates a potential listing price of approximately Rs 473, based on the upper end of the issue price. It is important to note that traditional valuation metrics such as Price-to-Earnings (P/E) or Price-to-Book (P/B) ratios for Tenneco Clean Air India were not disclosed in the available material, making a detailed comparative valuation challenging based solely on this information.
Based on the provided factual materials, specific regulatory, liquidity, or execution risks directly associated with this particular IPO were not disclosed. Prospective investors are advised to conduct thorough due diligence into the company's business and industry risks.
The robust subscription rates observed across various investor categories, especially from Non-Institutional Investors (NIIs), signal considerable market confidence in this IPO. Furthermore, the notable Grey Market Premium (GMP) implies a potential for positive listing day gains for investors, reflecting speculative interest. However, investors should carefully consider the pure Offer-for-Sale (OFS) structure of the IPO and the absence of detailed financial metrics in the provided information when formulating a comprehensive investment decision.
