Express Scripts reported financial performance for Q1-2017 yesterday. This is a good news / bad news story and the bad news far outweighs the good news. On the plus side, the company reported earnings of $546. 3 million ($0.90/share), which was up 4% from the same quarter last year. On a trailing 12 months basis, the company earned approximately $5.70 a share. Compared to a $67 share price, this translates into a PE of just under 12. This valuation metric and others like EV/EBITDA of 7.4 suggest the company is undervalued in the marketplace.
