Walgreens Boots Alliance has announced plans to close around 200 stores in the U.S. as part of the cost-reduction plan it first unveiled last August. The company, which is the largest U.S. drugstore chain, explained it has not yet decided which stores it will close, although it said it will not be focusing on any specific geographic area. Walgreens is aiming for a cost reduction of a projected $1.5 billion by the end of fiscal 2017, $500 million more than what the company expected last summer. The store closure announcement arrives at a time when the company is reporting stronger results for its domestic retail pharmacy business, which includes Walgreens and Duane Reade stores. That division posted second-quarter sales of $21 billion, up 7.4 percent from a year ago, with comparable sales up 6.9 percent. The retail pharmacy international division, which includes Boots in the U.K., saw sales increase by 2.9 percent to $2.0 billion. Walgreens Boots Alliance has been organized into three segments – Retail Pharmacy USA, Retail Pharmacy International and Pharmaceutical Wholesale. Total sales in the second quarter grew by 35.5 percent to $26.6 billion compared with the same quarter a year ago, largely due to the inclusion of Alliance Boots in the figures following the merger by Boots and Walgreens last year.
