But should it win applause from investors?
If the company's estimate of $2 billion in tobacco sales per year is accurate, the company is sacrificing 1.6% of its total annual take of $123 billion to this decision.
That could mean a significant hit to its annual top-line growth, which averages about 10% per year.
For the first three quarters, the company had sales of nearly $94 billion, and it reports fourth-quarter sales on Feb. 11. Analysts are expecting CVS to report fourth-quarter revenue of about $32.7 billion and earnings of $1.11 per share.
