After Fortinet provided lower than expected Q4 revenue and EPS guidance, JMP Securities analyst Erik Suppiger says checks indicate that the company's longer term opportunity is "still attractive." The analyst says that the company's guidance for 23% quarter-over-quarter billings growth indicates that its subscription pipeline is still healthy, while it has room to increase its sales force productivity. Additionally, Suppiger believes that the company is "a prime candidate for activist investors," given its "lagging growth "and "low operating margins." He keeps a $34 price target and Outperform rating on the shares.
