Piper Jaffray analyst Troy Jensen raised his price target for iRobot to $90 saying the company last night reported "another impressive quarter" with revenue above expectations and "significant upside" to margins and earnings. The analyst believes the company's higher guidance is beatable and anticipates ongoing upward revisions throughout year end. The robotic vacuum cleaner market is experiencing an inflection in demand and even with modest market share loss, iRobot can sustain 18%-20% growth rates for the next few years as penetration in households continues to increase, Jensen tells investors in a research note. He reiterates an Overweight rating on the shares.
