 Walgreens plans to close a significant number of its 8,600 stores in coming years and cut its stake in primary care provider VillageMD. It plans to reassign staff so there won't be significant job losses. Walgreens and other pharmacy chains have been making less from prescription drugs. Chief Executive Tim Wentworth tells the Wall Street Journal the company hasn't settled on a final number of locations to close, but it's reviewing about a quarter of unprofitable stores.
