CVS purchased Target's pharmacy business from the big box retailer in 2015 for $1.9 billion. It currently operates about 1,800 pharmacies within Target's 1,950 US locations.

Activist investor Glenview Capital said on Tuesday it had reduced its holdings in CVS Health following the insurer's "healthy" first-quarter results.

On June 11, many CVS customers woke up to a text from the pharmacy chain that said it would have to close its locations in Louisiana because of HB 358; which passed both the House and Senate.
