Fairway Market became a public company last April, but its disappointing quarterly earnings last month, with stocks down 30%, are riling up stockholders. Fairway and its top executives are fielding shareholder lawsuits seeking class-action status. The complaints allege that the New York grocer misled investors about its revenue. Fairway lost $31.3 million, or 74 cents per share, in the fiscal 2014 third quarter.
