One of Jack Dorsey's babies is having a very bad day.
Shares of Square plunged more than 20 percent Friday, putting it on track for its biggest daily loss ever, after the mobile payment firm reported a bigger-than-expected first-quarter loss.
The firm, one of two companies run by Dorsey, posted an adjusted quarterly loss of 14 cents a share on $379 million in revenue Thursday. Analysts had expected Square to post a loss of 9 cents a share on $344 million in revenue, according to a consensus estimate from Thomson Reuters.
