Tenneco Clean Air IPO Allotment Completed: Investors Gear Up for Listing Day

The allotment for the Tenneco Clean Air India Ltd IPO has now been officially completed, bringing some clarity for investors who were eagerly waiting to see whether their applications clicked. The issue, which opened on 12 November and closed on 14 November, attracted solid demand across all categories. With the IPO being entirely an Offer for Sale worth about ₹3,600 crore, the response shows strong confidence in the company’s positioning within the clean-air and automotive components segment.
Retail investors were particularly active due to the moderate entry point, with a lot size of 37 shares and a minimum investment requirement of around ₹14,689 at the upper price band. Meanwhile, institutional and non-institutional investors also showed healthy participation, signalling wider market trust ahead of the company’s market debut.
Applicants can now check their allotment status through the registrar’s portal using their PAN, application number, or Demat details. Those who did not receive shares can expect refund processing to start shortly, while successful investors will see shares credited to their Demat accounts before listing day.
Market sentiment around the IPO remains positive, backed by Tenneco’s long-standing relationships with major automobile manufacturers, its strong manufacturing footprint, and rising demand for emission-control technologies. The listing is scheduled on the BSE and NSE, and all eyes are on whether the stock can maintain the momentum seen during the subscription phase.
As always, investors are advised to track market conditions, review financial disclosures, and plan their listing-day strategy carefully. With the auto-component sector evolving and regulations pushing for cleaner vehicles, Tenneco Clean Air’s performance in the public markets will be closely watched.
