Piper Jaffray analyst Andrew Nowinski raised his price target for Proofpoint shares to $112 from $105 following the close of the acquisition of CloudMark. The stock closed Wednesday up 35c to $91.45. CloudMark should add $20M-$25M in revenue and billings to fiscal 2018 and should enable Proofpoint to further penetrate the Service Provider market, Nowinski tells investors in a research note. The analyst also continues to believe Proofpoint is a potential acquisition target itself. He keeps an Overweight rating on the shares.
