Explore how Tenneco Clean Air India Ltd performed during its IPO subscription phase, including early investor participation, issue size, price band, and details on how to apply through ASBA or UPI.
The Tenneco Clean Air India Ltd IPO opened for subscription on November 12, 2025, drawing initial investor attention within India’s automotive component and clean air technology sector. The company’s offering provides investors an opportunity to participate in India’s growing focus on sustainable mobility and emission control innovation.
The IPO of ₹3,600 crore consists of a public book-built issue with a price band set between ₹378 and ₹397 per share. On its opening day, the issue recorded 0.40x overall subscription, led by modest participation from Non-Institutional Investors (NIIs) and steady interest from retail investors.
On Day 1, the Tenneco Clean Air India Ltd IPO witnessed a measured start across investor categories. Retail and non-institutional investors accounted for most of the participation, while Qualified Institutional Buyers (QIBs) are expected to join in subsequent days.

The initial response highlights investor caution amid volatile market sentiment. However, participation from institutional investors could accelerate in the coming days as the bidding progresses.
The Tenneco Clean Air India IPO showed improved traction on Day 2, with notable interest from retail and NII investors. By the end of the second day, the overall subscription reached 3.08 times, supported mainly by strong participation outside the institutional segment.

Retail Individual Investors (RII) |

Non-Institutional Investors (NII) |

The NII segment recorded the highest activity, significantly oversubscribing its portion, while retail investors crossed the full-subscription mark. QIB participation remained minimal ahead of the final bidding day.
On Day 3, the Tenneco Clean Air India IPO witnessed a sharp rise in demand across all investor categories, marking a strong finish to the subscription window. By the end of the final bidding day, the overall issue was subscribed 12.84 times, led by substantial interest from both institutional and non-institutional investors.

This significant jump from earlier day trends reflects heightened investor confidence in Tenneco Clean Air India’s market positioning and long-term growth potential. The strong participation from QIBs and NIIs especially highlights the optimism surrounding the company’s future performance within India’s industrial solutions segment.
The Tenneco Clean Air India Ltd IPO price band is set between ₹378 and ₹397 per share, with a face value of ₹10 per equity share. Investors can bid for a minimum of 37 shares (1 lot) and in multiples of 37 shares thereafter.

You can also apply via your broker or trading platform using UPI-based applications:
Log in to your Demat account or trading account.
Navigate to the IPO section and select ‘Tenneco Clean Air India Ltd IPO’.

Alternate Investment Funds offer unique opportunities for portfolio diversification and potential outperformance, especially in niche and high-growth sectors. However, their complex structure, long lock-ins, and higher risk make them suitable for experienced investors only. A well-researched approach, along with professional advice, is essential before committing capital to an AIF.
The information provided above is based on publicly available data from reliable financial news and market sources. Investors are advised to verify figures and consult financial experts before making investment decisions. Market conditions and subscription numbers are subject to change during the IPO window.
