United Natural Foods shares surge 13.74% premarket after raising 2025 sales guidance despite cyberattack impact.

United Natural Foods surged 13.74% in premarket trading following a revised 2025 sales outlook and management’s confidence in navigating a recent cyberattack. The company raised its fiscal 2025 net sales guidance to $31.6 billion–$31.8 billion, citing strong year-to-date performance, while stating insurance proceeds would cover incident costs. This update, combined with ongoing cost-saving initiatives in its conventional products segment, signaled resilience to investors, driving the sharp premarket increase. The move aligns with Reuters’ report of an 8% premarket jump attributed to the revised guidance and operational clarity.
