CVS is the largest pharmacy and drugstore chain in the United States, with more than 9,700 locations in 49 states, more than 1,100 MinuteClinic locations, and serving 5 million customers per day. With the threat of (AMZN) entering the pharmacy business looming large, CVS is going on the offensive and looking to buy health insurance company Aetna Inc. (AET) in a $66 billion deal.

These are the four largest individual shareholders in CVS.

Larry J. Merlo

Merlo was an assistant manager at one of the drugstores and worked his way up to CEO in March 2011. Under Merlo the company has been aggressive about buffing up its health section, making massive acquisitions like their $2.1 billion purchase of Coram, an enteral nutrition (tube-feeding) company, and shelling out $12.7 billion for Omnicare, which supplies prescription drugs to nursing homes. 

As of his Sept. 15 SEC filing, Merlo owns 299,255 shares of CVS stock, with an additional 365,115 in a trust, making him the company's largest shareholder.
