Vistra Corp. (VST)
Summary and key takeaways
Vistra reported Q2 2026 adjusted EBITDA of $1.767 billion, up more than 30% year-over-year, on revenue of $4.017 billion that declined 5.5% and missed consensus — the stock slipped on the revenue miss despite the strong EBITDA growth. Adjusted EPS of $1.80 beat the $1.54 consensus by nearly 17%, while GAAP net income of $305 million absorbed a $472 million unrealized hedge-related loss. Management reaffirmed full-year 2026 guidance and maintained its 2027 outlook despite softer forward power prices in ERCOT.

Analysis
Same pattern as Talen this quarter, for similar structural reasons: the top-line revenue number missed and fell year-over-year, but the metrics that actually describe the health of Vistra’s generation and retail businesses — adjusted EBITDA, adjusted EPS — both beat and grew meaningfully. The 68% jump in generation-segment EBITDA is the number that matters most: it reflects the restart of Martin Lake Unit 1, the Lotus acquisition contribution, higher PJM capacity revenues, and favorable hedging, all pointing to the same power-demand tightness thesis behind this position.
The $472 million unrealized hedge loss that dragged on GAAP net income is a mark-to-market accounting item on positions that settle over future years, not a cash loss today — the same dynamic showing up at Talen this quarter. It’s a useful reminder that GAAP net income is often the wrong number to anchor on for merchant power generators with active hedge books.
Management’s decision to reaffirm full-year guidance and hold the 2027 adjusted EBITDA midpoint despite acknowledging softer ERCOT forward power prices is worth noting — it suggests the PJM and broader-market strength is more than offsetting any ERCOT softness, at least for now.
Guidance
- Full-year 2026 adjusted EBITDA guidance reaffirmed at $6.8–7.6 billion
- Full-year 2026 adjusted free cash flow before growth reaffirmed at $3.925–4.725 billion
- 2027 adjusted EBITDA midpoint opportunity of $7.4–7.8 billion maintained despite softer ERCOT forwards
Updated investment thesis
VST is a small Growth-bucket position on the same data-center power-demand tightness thesis running through TLN and, more indirectly, VRT. This quarter’s EBITDA and EPS beats, driven by generation-segment strength, are consistent with that thesis; the revenue miss and GAAP hedge-loss headline are both noise relative to the underlying operating trend.
No position changes from this report. At just 0.97% of the book, this remains a small, exploratory-sized position — I’d want to see a couple more quarters of the generation-segment strength continuing before considering adding meaningfully.
Risks to this position
- ERCOT softness: management explicitly flagged softer forward power prices in ERCOT, Vistra’s largest single market — a trend worth watching for signs of broadening.
- Hedge accounting volatility: large unrealized mark-to-market swings will continue to make GAAP net income a noisy, sometimes misleading, headline number.
- Revenue-growth optics: a falling top line, even alongside EBITDA growth, can weigh on sentiment and multiple even when the underlying business is healthy.
- Same macro dependency as TLN and VRT: all three positions are leveraged to continued data-center capex and power-demand growth; a slowdown in AI infrastructure buildout would pressure all three simultaneously.
