According to a report from The Wall Street Journal, Yelp is exploring a sale.
Following the news, shares of the company were up as much as 25% and were at one point halted for volatility.
The Journal's report, which cites people familiar with the matter, said the company could be valued at up to $3.5 billion in a sale.
It also said the company has been working with banks and had been in touch with potential buyers in recent weeks.
The company's current market cap is about $3 billion.
But The Journal's report added that a sale is not imminent and the company could decide against it.
Last week, shares of the company were crushed, falling about 20% after an earnings report that disappointed.
In the first quarter, the reviews site lost more money than expected while revenue fell short of estimates, and for the full year the company said it would likely bring in less revenue than Wall Street analysts had been expecting.
Here's the crazy spike in Yelp shares on Thursday.
