The second-largest insurer in the U.S. faced a year of challenges as the Affordable Care Act went into effect and new CEO Joseph R. Swedish took the reins. Wellpoint completed its integration of Amerigroup, which gave the company the largest Medicaid roster in the industry with nearly 4.5 million patients, and refocused its core business by selling off 1-800 CONTACTS and Glasses.com. The insurer reported sales growth of 16% in 2013, to $71.5 billion, though profits dropped over 6% year-over-year. Swedish said he expects 2014 income to be better as the company adds as many as 1.3 million net new customers, an increase driven by the public exchanges set up under the ACA.
