Credit Suisse analyst Michael Weinstein upgraded Vistra Energy to Outperform from Neutral as merger integration proceeds smoothly and with potential upside from market and legislative developments. His upgrade is based on improved confidence and better visibility into the company's future trajectory as management steadily executes its plan and delivers on key initiatives including share buyback, retail expansion with combined retail/wholesale risk mitigation, merger synergies, dividend program, fleet optimization, and growth opportunities. Weinstein also raised his price target on the shares to $32 from $26.
