A record quarter and a new growth vector

Vistra delivered another strong quarter, with second-quarter Adjusted EBITDA of $1.767 billion, up more than 30% year-over-year, driven by both generation and retail. The company reaffirmed its 2026 guidance and maintained its 2027 midpoint opportunity range despite softer ERCOT forwards. But the most notable development was the announcement of a partnership with KKR, NVIDIA, and the Kuwait Investment Authority to form Helix Digital Infrastructure, a platform that aims to combine power solutions with digital infrastructure. “We're excited about the opportunity. We think this is, again, a customer orientation, and we view that the chance to market our current assets as well as develop some new ones with someone who has a much greater access to capital in a sense that if it's required to do things like powered shells, powered land, that's something we don't believe our shareholders are expecting us to put a lot of capital in, given our core business.” — Jim Burke, President and Chief Executive Officer · 2026-08-07 Vistra will commit up to $1 billion over time, with $500 million earmarked initially. This is a fresh theme for Vistra, as Helix is a new entrant and a significant strategic pivot toward a broader digital infrastructure play.

Batch Zero and the Texas audit

The Texas data center market remains a key focus. Governor Abbott's directive to audit interconnection queues has paused some of the Batch Zero studies, but Vistra remains confident.

I'd like to see the queues culled. At the end of the day, I think everybody, if we raise the criteria and raise the bar on what is being proposed from the data center load, an ERCOT queue that has at times been expressed as over 400 GW, we think is somewhere in the 12 GW to 15 GW by 2030.

Batch Zero is the current top global keyword, indicating this is a market-wide theme. Vistra's Batch Zero experience underscores its position as a key player in connecting large load.

ERCOT vs PJM: Hedging and the forward curve

The company highlighted the divergence between ERCOT and PJM, with ERCOT forwards softening on near-term weather and battery oversupply, while PJM strengthens on capacity needs. Kris Moldovan provided perspective on 2027: “I would say that they don't fully offset the ERCOT headwinds, so we would be trending towards the lower end of that range.” — Kris Moldovan, Executive Vice President and Chief Financial Officer · 2026-08-07 This is where the comprehensive hedging program and the nuclear PTC provide downside protection, a theme that has been recurring. Vistra's comprehensive hedging and its higher prices in PJM are central to bridging the gap.

Capital allocation and the balance sheet

Beyond growth, Vistra remains a capital return story. Kris noted that the buyback program has retired 171 million shares at an average cost of $38, and the company expects to exhaust its current authorization by end-2027. The company also aims for mid-investment-grade ratings, having already achieved investment-grade from two agencies. This is supported by strong cash generation. The fundamentals show robust revenue growth: Total Revenue rose 33% year-over-year to $5.6B, and operating margin expanded to 26.6%. Vistra's ability to fund both growth and buybacks relies on this cash engine. Prior calls previewed this trajectory. On the May 2026 call, Jim Burke noted, “The activity level has remained as high as we've ever seen in this.” — James Burke, President and Chief Executive Officer · 2026-05-07 And on the same call, Stacey Doré said, “Continuing to engage at the same level that they have been.” — Stacey Dore, Executive Vice President and Chief Legal Officer · 2026-05-07 These comments underscore that the data center demand environment has been consistently strong, and Vistra is positioning to capitalize.
