What Vistra’s Q2 Earnings Reveal About Its $1 Billion Helix Bet

Key Takeaways for Vistra Stock as of August 2026

• Mixed Headline Print: Vistra’s Q2 revenue of $4.017B missed the Street’s $5.521B estimate by 27.24% and slipped 5.48% YoY, yet adjusted EBITDA of $1.767B beat consensus by 6.53% and climbed more than 30% YoY.
• 2026 Guidance Reaffirmed: Management held 2026 adjusted EBITDA guidance at $6.8B to $7.6B and adjusted free cash flow before growth at $3.925B to $4.725B, and said results should land at or above the midpoint.
• Margin Expansion: EBITDA margin widened to 43.42%, landing 1,376bps above the Street’s 29.65% estimate and 1,207bps above Q2 2025’s 31.34% mark.
• Queue Reality Check: CEO Jim Burke pushed back on an ERCOT interconnection queue “expressed as over 400 gigawatts,” arguing the real data center demand is “somewhere in the 12 to 15 gigawatts by 2030.”

Vistra’s Q2 Earnings Show a Revenue Miss Hiding a Margin Surge

Vistra (VST) delivered a second quarter that split its own scoreboard. Revenue of $4.02 billion missed the Street’s $5.52 billion estimate by 27%, even as adjusted EBITDA of $1.77 billion cleared consensus by 7% and grew more than 30% from a year earlier. The gap between those two lines is the real story of the quarter: EBITDA margin widened to 43.4%, more than 13 percentage points above what analysts had modeled and up from 31.3% in the same period last year.

That margin expansion traces to the generation and retail segments working in tandem. Generation contributed roughly $994 million of adjusted EBITDA, up from $593 million a year ago, driven by favorable hedging, higher PJM capacity revenue, and the restart of Martin Lake Unit 1. Retail added $773 million, roughly flat with last year’s $756 million. Behind both figures sat an operational push through spring maintenance and 92 planned outages ahead of peak season. CEO Jim Burke described the payoff directly on the Q2 earnings call: “This preparation was evident during the recent heat waves in Texas and PJM, where we achieved commercial availability of over 97% across the entire fleet.” That availability, delivered while ERCOT and PJM both hit all-time summer peaks, is what let the hedge book capture margin the raw revenue print doesn’t show.

Below the EBITDA line, the picture gets choppier. EBIT of $553 million missed the Street’s $1.05 billion estimate by 47%, even while growing 7% YoY. Net income of $576 million rose 134% YoY but still landed 6% below consensus, and operating cash flow of $1.02 billion missed by 36%. Capex came in 18% lighter than modeled at $689 million, a rare beat that partly offset the cash flow shortfall.

None of that shook guidance. Vistra reaffirmed 2026 adjusted EBITDA guidance of $6.8 billion to $7.6 billion and adjusted free cash flow before growth of $3.925 billion to $4.725 billion, with management confident in landing at or above the midpoint. The 2027 opportunity range held at $7.4 billion to $7.8 billion too, even as ERCOT forward curves softened, because PJM strength, the hedging program, and nuclear production tax credit protection offset the gap. CFO Kris Moldovan flagged that figure excludes the pending Cogentrix acquisition and the Meta nuclear power purchase agreement, which could add roughly $700 million to the midpoint once finalized. Layered on top, Vistra committed up to $1 billion as a founding investor in the Helix Digital Infrastructure platform alongside KKR, NVIDIA, and the Kuwait Investment Authority, positioning itself as Helix’s preferred power partner for data center deals.

Vistra just proved its hedge book can turn a soft revenue quarter into a margin beat, and now it’s betting on Helix to extend that model into data centers. Track the next data point on TIKR for free

TIKR’s Model Prices Vistra Stock at $184 Through 2030

TIKR’s mid-case model values Vistra at $184 by December 2030, implying a 31% total return from the current price of $141, or 6% annualized over 4.4 years.

That annualized rate reads as a measured, hedge-protected compounding case rather than a re-rating bet, appropriate for a merchant power stock still absorbing near-term ERCOT curve softness while its longer-dated demand story plays out.

The target rests on the same dynamics visible in the second quarter: a hedging program and generation mix that converted a 27% revenue miss into an EBITDA beat, a 2026 guide management is confident will land at or above midpoint, and a 2027 range held intact despite softer ERCOT pricing. Add the Helix platform and the pending Cogentrix and Meta transactions, both excluded from current guidance, and the model’s path to $184 looks built on numbers already on the table rather than numbers still to come.

Vistra just showed its guidance can absorb an ERCOT pullback without cracking. See what TIKR’s model says comes next, on TIKR for free →.
