Cantor Fitzgerald analyst Steven Halper lowered his price target for Vocera Communications to $36 from $40 and reiterates an Overweight rating on the shares. The company's Q2 results were "strong," however, combined backlog and deferred revenue increased just 6% year-over-year, Halper tells investors in a research note. Based on company commentary, the analyst believes a handful of contracts did not sign, but he notes that Vocera has received verbal commitments. With delayed signings, the company reduced its 2019 revenue guidance by about 3% at the mid-point of the range, Halper points out. The analyst, thought, still expects a stronger second half of 2019. Market dynamics support the return to mid-teens top-line growth next year, says the analyst.
