CVS Health will close hundreds of drugstores over the next three years, as the health care giant adjusts to changing customer needs and converts to new store formats.

The company said Thursday that it will close about 300 stores a year for the next three years, nearly a tenth of its roughly 10,000 retail locations as it reduces store count density in some places.

CVS Health said it has been evaluating population changes, customer buying patterns and future health needs to “ensure it has the right kinds of stores in the right locations.”

The company also has been expanding the health care services it provides at many locations.

The closings make sense as CVS Health seeks to remake many stores into more of a “one-stop shop” for care, Edward Jones analyst Ashtyn Evans said, adding that the company’s Aetna health insurance business should steer customers to those stores.

The company released no details Thursday on where the closings will occur. It did say they would start next spring.

Major drugstore chains routinely close underperforming stores or shutter locations for other business needs.

The growth of online shopping has blunted the need for CVS and Walgreens to operate a vast network of drugstores that are just a few minutes’ drive from most American homes.

CVS Health said Thursday its stores will be grouped into three models.

Shares of Woonsocket, Rhode Island-based CVS Health Corp. rose 3% to $95.55 Thursday afternoon while broader trading indexes were nearly flat.
