It seems that the four-year- old merger of CVS Caremark is on the brink of collapse.  For a long time, a cohort of consumers and independent pharmacists has been pressurizing the Federal Trade Commission (F.T.C) to dig into the nook and crannies of the business collaboration of the drugstore chain, CVS and the pharmacy benefit manager, Caremark.

Despite of assertions of successful merger for the benefit of serving effective health plans, the company failed to fulfill the expectations of the investors as it lost nearly $5 billion in contracts with employers and health plans for 2010.

Moreover, market analysts had predicted that company has been overvalued at revenue of $96.41 billion in 2010, down from $98.73 billion in 2009.

With a consistent track of poor financial performance and unfulfilled promises to the customers, the group wrote a letter accusing the company of indulging in unfair business practices for their benefit.

Responding to the speculations about the demerger, Carolyn Castel, a company Spokeswoman affirmed that company has no plans of splitting the business unit and further, assured that they are giving full support to the inquiry conducted by F.T.C and another multistate inquiry by the attorneys general of 24 states.

Defending the company, Ms. Castel asserted that company has always taken stern stand for consumer benefit and never intends to harm consumers or other stakeholders.
