Vistra (VST) drew fresh attention after reporting second quarter results that included higher adjusted EBITDA and a reaffirmed 2026 outlook, along with a new data center focused partnership with KKR, NVIDIA, and the Kuwait Investment Authority.

Despite the fresh partnership news and higher adjusted EBITDA, Vistra's recent share price momentum has cooled, with the stock down about 11.5% over the past month and 14.9% year to date. Its 1 year total shareholder return remains sharply lower than its very large 5 year total shareholder return of more than 7x.

Vistra Corp is on a discount. AMZN, META, Quantom Capital group, and many more. All of these are known to many. But Vistra is the one behind them that allows these companies to excel in their sector. Both AMZN and META made a 20 year energy deal with them. What does this mean? AWS centers that run Chat GPT, Claude, Netflix, Disney, Spotify, Canva, Adidas, JP Morgan Chase are all affected by Vistra's energy. Big names, isn't it?

Curious how this narrative justifies nearly doubling Vistra's current price? The engine room is long dated power demand, expanding capacity, and margin assumptions that treat Vistra more like core infrastructure than a typical utility. The full narrative lays out how those pieces are expected to feed into future cash flows and the resulting fair value.

Result: Fair Value of $299.98 (UNDERVALUED)
