What happened Shares of organic and natural foods distributor and supermarket operator United Natural Foods (NYSE: UNFI) tumbled 27.5% through 11:15 a.m. Despite edging out analyst predictions for $7.8 billion in sales for its fiscal second quarter of 2023, United Natural Foods whiffed badly on earnings, reporting a non-GAAP (adjusted) profit of only $0.78 per share where Wall Street had expected $1.46. But "profits were challenged," CEO Sandy Douglas said, pointing to "accelerating inflation" and "supply chain volatility" as two of the culprits for United Natural Foods missing analysts' earnings target.
