Vistra’s upside is less about raw megawatts and more about upgrading the quality of cash flows: higher capacity payments in tight markets, more multi-year contracting for firm delivery, and improved credit profile that supports a durable cash-flow
multiple. The 2027/2028 capacity auction outcomes and the move toward long-dated nuclear contracting improve visibility, which matters in an economy where reliability is monetized. The main limiter is that the market already prices meaningful scarcity, so the path to outperformance requires clean execution (availability, safety, contracting discipline) and avoiding policy whiplash.
