Cigna's unit to invest $3.5 billion in specialty pharmacy firm Shields
The investment comes as Shields transitions to a private company following the acquisition of its former parent, Walgreens Boots Alliance, by Sycamore Partners for $10 billion. Specialty pharmacies sell medications that require extreme care in handling, storage and distribution, often for patients with complex conditions such as cancer, multiple sclerosis and rheumatoid arthritis.
