Deutsche Bank analyst Gregg Gilbert says 2018 consensus estimates for Valeant Pharmaceuticals look too high after he updated his model to reflect a more conservative view. The analyst now assumes more significant erosion for the company's Dermatology segment and more modest growth for Salix in 2018. His 2018 earnings per share estimate of $3.05 is well below the consensus at $3.54. Gilbert, however, continues to see the potential for "solid" growth beyond 2018, which represents a "trough year" in his model. He keeps a Hold rating on Valeant shares with a $19 price target.
