Shares of Voltamp Transformers Ltd. fell nearly 3% to ₹7,560 on Tuesday, September 9, after a large block deal worth ₹618 crore took place during early trade.

Block deal details

As many as 8.12 lakh shares, representing about 8% of the company’s equity, were traded at an average price of ₹7,611 per share. According to sources cited by CNBC-TV18, promoter Kunjal Patel is likely the seller in this transaction.

This marks Patel’s second major stake sale in a year. In September 2023, he had sold a 12% stake at ₹4,633 per share. Post this latest deal, promoter holding is expected to fall below 30%, with shares subject to a two-year lock-in if the full 7.8% stake is offloaded.

Market performance and financials

Voltamp has had a mixed financial trajectory since the first stake sale. Revenue rose 11% from Q2 FY24 to Q1 FY26, but margins contracted 90 basis points to 17.1%. Net profit, however, grew by 16% over the same period.

The stock, despite Tuesday’s correction, remains up 66% since the September 2023 block deal. However, it is still down 25% year-to-date and has corrected 46% from its 52-week high of ₹14,880 touched in August 2024.
