More bad news for an organic grocery chain.

Shares of Sprouts Farmers Market plunged by more than 9% in after-hours trading on Thursday after the company reported first quarter earnings and sales below expectations.

The drop in Sprouts follows bad news from Whole Foods on Wednesday, which saw shares get crushed after it posted a miss on revenues.

Sprouts reported net sales of $US857.5 million, up 19% year-over-year below expectations for $US863 million, according to Bloomberg.

The company posted diluted earnings per share of $US0.25, just below the estimate for earnings of $US0.26. Same store sales were also a miss, growing below expectations at 4.8% against expectations for 5.6% growth.

Sprouts, like Whole Foods, facing intense competition as sales of organic food explodes in the US.

Organic food sales more than tripled from $US11 billion in 2004 to about $US35 billion in 2014, according to the Department of Agriculture.

Sprouts Farmers expects to add 27 new stores this year, and anticipates net sales growth of between 20% and 22%.
