CVS Health Corp. provided an earnings forecast for next year that’s lower than analysts have predicted, and projected that results for the rest of 2016 will also come in below expectations at the drugstore chain as prescriptions slow.

Third-quarter earnings, excluding some items, were $1.64 a share, the Woonsocket, Rhode Island-based company said in a statement, compared with the $1.57 average of analysts’ estimates compiled by Bloomberg. The beat was partly from lower-than-expected taxes in the third-quarter.
