Whole Foods Market’s stock fell more than 7 percent after hours on Wednesday and again Thursday after the chain reported quarterly profit and revenue below analysts’ forecasts. The 373-store chain had profit of $158 million, up from $146 million a year earlier. Revenue rose 10 percent to $4.24 billion. It cut its annual earnings forecast for the second time since November and now expects $1.65 to $1.69 per share. The company says growth is the key: It signed 57 new leases in the past year and will cross the 500-store mark in 2017.
