Cantor Fitzgerald analyst Steven Halper says Vocera Communications' commentary at recent conferences remains positive regarding the company's growth outlook. While the company's first half of 2019 performance was challenged due to the Smartbadge introduction and some deal slippage experienced in Q2, it can return to mid-teens revenue growth and expand adjusted EBITDA margins, Halper tells investors in a research note. He believes Vocera has multiple avenues to accelerate operating performance going forward and sees an "attractive opportunity" for investors with 48% upside potential to his $36 price target. The analyst remains confident in Vocera's future growth trajectory and reiterates an Overweight rating on the shares.
