However, Romanelli said Fortinet (FTNT) “has done a tremendous job growing its business over the last several years,” as evidenced by the its year-over-year revenue growing by 20%, 29% and 32% in each of the last three years.

Romanelli said Fortinet (FTNT) “has clearly strengthened its competitive positioning over this timeframe, and has taken significant share in the network security market.”

While he lowered his rating on Fortinet’s (FTNT) stock, Romanelli left his $60-a-share price target unchanged.
