Once again we find Zeltiq boosting its outlook. This is something that it has done with every passing quarter, after initiating annual guidance dating to the start of 2013. Zeltiq now expects to generate between $235 million and $238 million in revenue in 2015, up from its January forecast of $230 million to $235 million on the top line. Zeltiq is also inching its guidance for adjusted EBITDA higher.
