The Tenneco Clean Air IPO was one of the most talked-about public offers of 2025, and if you applied, you’re probably eagerly waiting to see if you got shares. With the IPO being heavily oversubscribed, the allotment process is competitive.

This guide will walk you through everything you need to know—from how to check your Tenneco Clean Air IPO allotment status to what the results mean for you as an investor.

IPO at a Glance: The Key Details

Before we get to the allotment, here’s a quick recap of the offer:

• IPO Dates: The subscription window ran from November 12 to November 14, 2025.
• Price Band: ₹378 to ₹397 per share.
• Lot Size: 37 shares.
• Allotment Finalization: The Tenneco Clean Air IPO allotment is expected to be finalized on November 17, 2025.
• Listing Date: Shares are tentatively set to debut on the BSE and NSE on November 19, 2025.

How to Check Your Allotment Status (Step-by-Step)

Once the allotment is finalized on November 17, you can check your status through these methods:

1. Via the Registrar’s Website (MUFG Intime)
This is the most direct method.

• Go to the MUFG Intime IPO allotment status page.
• Select “Tenneco Clean Air” from the dropdown list of IPOs.
• Enter your PAN number, Application Number, or Demat Client ID.
• Click ‘Submit’ to see your status.

2. Through the BSE or NSE Websites

• BSE: Visit the BSE IPO status page, select ‘Equity’ and then “Tenneco Clean Air” from the list.
• NSE: Go to the NSE IPO application status section.
• On either site, enter your application details or PAN card number to check.

3. Through Your Broker or Demat Account
This is often the easiest way. Once the allotment is complete, simply log into your trading or demat account (like Angel One, Zerodha, etc.). If your application was successful, the shares will be credited to your holdings by the end of November 18.

What the Subscription Numbers Tell Us

The IPO saw massive demand, which is why checking your allotment is so crucial:

• Overall Subscription: 61.79 times.
• Retail Category: 5.37 times.
• Institutional Investors (QIBs): A huge 174.78 times.

This high oversubscription means the allotment is done via a computerized lottery. Not every application will get shares, and even successful applicants might not get the full number of lots they applied for.

Grey Market Premium (GMP) and Listing Outlook

Before listing, the Tenneco Clean Air IPO GMP was very strong, hinting at a potential listing pop of around 29% above the issue price.

However, it’s important to be cautious. Early reports after the debut noted the stock initially dipped by about 5%, showing that even with high demand, there can be initial volatility. Don’t assume the listing gain is guaranteed.

The Investor Conversation: Bullish Views and Key Risks

The IPO has sparked a lot of discussion among investors:

The Bull Case:

• Many brokerages (about 12) are positive, citing the company’s strong focus on clean-air technology and its valuable relationships with major automakers (OEMs).
• Its high Return on Capital Employed (ROCE) of ~56% shows impressive profitability.

The Concerns:

• On forums like Reddit, some investors have raised governance risks, pointing to potential weak internal controls.
• As an auto-component company, its business is cyclical and tied to the health of the automotive industry.
• With the high oversubscription, retail investors are noting that the chance of allotment is low, with some estimating only 1 in 4 applications might be successful.

Your Next Steps as an Investor

1. Check Your Status: On or after November 17, use the methods above to check your Tenneco Clean Air India IPO status.
2. Understand the Outcome:
   • If you get shares: Decide your strategy. Are you in for a quick profit on the listing date, or do you believe in the long-term clean-air story?
   • If you don’t get shares: Don’t be discouraged. The high oversubscription made it a lottery. You can always consider buying the stock from the open market after listing.
3. Monitor the Listing: Keep an eye on the stock when it lists on November 19. Be prepared for potential price swings.

The Tenneco Clean Air IPO represents a compelling bet on the future of automotive technology. Whether you’re a short-term trader or a long-term investor, being informed is your biggest advantage. Good luck, and we hope you get a successful allotment
