Longtime CVS Health executive David Joyner has replaced Karen Lynch as CEO, as the company struggles to drive higher profits and stock performance, CVS announced Friday.
The move, effective Thursday, comes as CVS shares have fallen nearly 20% this year.
CVS has faced challenges as higher medical costs weigh on its insurance unit, Aetna, and consumer spending drops at its retail pharmacies. In August, the company slashed its full-year profit guidance and said it would cut $2 billion in costs over the next several years.
In its release Friday, CVS said it expects adjusted earnings of between $1.05 and $1.10 per share in its third quarter. It anticipates higher medical costs than previously expected, with a so-called medical benefit ratio of 95.2% in the quarter.
CVS shares plunged about 11% in premarket trading Friday.
