Vistra Completes Acquisition of Cogentrix Energy, Expanding Diverse Generation Fleet

NEWS RELEASE

Approximately 5,500 megawatts of modern natural gas capacity in key markets enhance company's ability to meet customer needs

IRVING, Texas, Oct. 30, 2026 — Vistra Corp. (NYSE: VST) today announced it has completed the acquisition of Cogentrix Energy, consisting of 10 modern natural gas generation facilities totaling approximately 5,500 MW of capacity, from funds managed by Quantum Capital Group. The transaction closing follows receipt of all required regulatory approvals. Combined with Vistra’s existing fleet, the additional assets bring Vistra’s generation portfolio to nearly 50,000 MW of capacity across the U.S.

With this acquisition, Vistra further expands its diverse generation portfolio, adding efficient combined-cycle combustion turbine and cogeneration assets in some of the most attractive and fastest-growing power regions in the country: PJM, ISO New England, and ERCOT. The closing builds on Vistra's track record of completing and integrating large acquisitions, including Energy Harbor in March 2024, which added approximately 4,000 MW of nuclear generation, and seven natural gas plants from Lotus Infrastructure Partners in October 2025, which added more than 2,300 MW of capacity to Vistra’s current fleet.

“Natural gas plays a critical role in meeting our nation’s growing energy needs, and the Cogentrix assets are a strong strategic fit for Vistra as we continue to grow our generation portfolio,” said Jim Burke, president and chief executive officer of Vistra. “We’re excited to bring these experienced teams together around a shared commitment to safety, operational excellence, and reliability. Our Vistra team knows how to successfully integrate generation assets into our fleet, and we look forward to building on Cogentrix’s strengths and delivering long-term value for our stakeholders.”
