Roth Capital analyst Craig Irwin upgraded Capstone Turbine to Buy from Neutral and raised his price target on the shares to $2 from 65c, as he believes recent storm activity in the U.S. and the Caribbean should support rebounding revenue. The analyst sees precedents from Hurricane Sandy, where Capstone saw strong uptick in activity across the N.Y. metropolitan area, and $10M incremental demand over the next 18-24 months. With Florida, Texas, and the Caribbean affected by recent storms, Irwin estimates there could be as much as $30M incremental demand.
