Shares of Tenneco Clean Air India Ltd fell as much as 5% on Wednesday, hitting a day’s low of ₹525 after a large block deal in the stock.

Around 3.2 crore shares, close to 8% of the company’s total outstanding equity, changed hands in the deal.

The average price worked out to ₹529 a share, putting the overall transaction value at about ₹1,699 crore.

The identities of the buyers and sellers have not been made public yet. The stock has had a volatile run since its listing in November last year.

It has touched a 52 week high of ₹657 in May and a low of ₹438 in December, and is still up 7.6% on a year to date basis even after Wednesday’s fall.

Over the past one month, though, the stock is down close to 8%. The block deal comes just days after the auto parts maker reported its numbers for the June quarter.

Revenue for Q1FY27 rose 20% year on year to ₹1,545 crore from ₹1,286 crore a year earlier. Value added revenue climbed 18% to ₹1,381 crore.

EBITDA grew a more modest 8% to ₹247 crore, though the margin slipped to 17.9% from 19.6% in the same quarter last year. Net profit dipped 2% to ₹165 crore compared with ₹168 crore a year ago.

CEO Arvind Chandra said last week that the company expects double digit revenue growth to continue through FY27, helped by steady demand from domestic OEMs, rising exports and market share gains in its suspension business.

He flagged risks like the West Asia conflict and tariffs but said India remains a strong growth market overall.

He also said Tenneco is actively looking at acquisitions across ICE, hybrid and EV segments, backed by a debt free balance sheet.

At 11:30 am, the stock was trading at ₹543.40, down 1.31% for the day.
