Vistra Corp. (VST)

Constellation Energy (NASDAQ:CEG), with its substantial nuclear fleet, is increasingly positioned as a critical power provider for the AI era. The company is securing long-term clean-power agreements with major technology customers due to the surging electricity demand from data centers. Constellation's strategy involves expanding capacity through reactor uprates and life extensions, capitalizing on the need for reliable, carbon-free, round-the-clock power.

Vistra Corp. CEO James Burke indirectly purchased 2,000 shares of the company's stock for $270,000 on August 24, 2026, after the stock experienced a 29% decline over the preceding 12 months. This transaction, executed through JAMEB, LP, increases his total beneficial interest to approximately 1.2 million shares, valued at $167.63 million. Burke's purchase signals strong executive confidence in Vistra's valuation, especially after a Q2 earnings report that saw a stock sell-off due to an unrealized hedging loss, despite significant growth in adjusted EBITDA and the company's involvement in a joint venture supporting AI data centers.
