Shares of Indian food delivery firm Zomato dropped as much as 14.3% on Monday to an all-time low after the end of the lock-in period for investors who had stakes in the company prior to the initial public offering.

The stock dropped to as low as 46.15 rupees apiece, giving the company a market cap of $4.5 billion, far below the $13.2 billion valuation it accrued on its debut day a year ago.

Zomato had raised $1.3 billion ahead of the listing from scores of investors including Tiger Global, Fidelity, Government of Singapore, Canada Pension Fund, T. Rowe Price, Morgan Stanley and Steadview. The investors had subscribed the shares at 76 rupees. Shareholders and founders owned about 78% stake in the company before the listing and were permitted to sell without disclosure from July 23.

Shares of the company, which has lost more than 60% of their value since the listing day last year, have been feeling addition pressure of late following Zomato’s recent proposed acquisition of instant delivery firm Blinkit in a deal that many analysts say is overpriced and riddled with conflict of interest.

Zomato competes with Swiggy, a much younger firm which raised capital in a round from investors including Invesco at a valuation of $10.7 billion earlier this year. With the acquisition of Blinkit, the Gurgaon-headquartered firm is looking to enter the instant grocery delivery space, a capex heavy category where it has traditionally struggled and meet even more competitors including Y Combinator-backed Zepto.
