Guggenheim analyst Shahriar Pourreza's bullish outlook for Vistra is anchored by nuclear power purchase agreements (PPAs) with AWS and Meta, covering over 3,800 MW, and rising capacity market pricing. This contrasts with the Wall Street consensus target of $217.42, implying 59% upside. Vistra shares have declined 14.78% year-to-date and 29.93% over the trailing year, underperforming the S&P 500's 12.82% YTD gain. The company's Q2 2026 revenue was $4.02 billion, down 5.5% YoY, with GAAP net income at $305 million. However, underlying Ongoing Operations Adjusted EBITDA climbed over 30% YoY to $1.77 billion. The 2027 outlook, with management flagging "meaningfully lower" ERCOT forward curves, has reset expectations for the AI power sector.
