Vistra (VST) Q3 2026 Earnings Call Transcript

Vistra reported record Q3 2026 adjusted EBITDA of $2.378 billion, up more than 50% from $1.581 billion a year earlier, and raised the midpoints of its 2026 guidance ranges to $7.1–$7.5 billion in adjusted EBITDA and $4.3–$4.7 billion in adjusted free cash flow before growth. It introduced 2027 guidance of $7.7–$8.5 billion in adjusted EBITDA and $4.3–$5.1 billion in adjusted free cash flow before growth, including expected Cogentrix and Meta PPA contributions; the $4 billion Cogentrix acquisition added approximately 5,500 MW and closed Oct. 30. The board authorized an additional $1.5 billion in buybacks, leaving $2.5 billion of authorization, while management cited lower near-term ERCOT prices and interconnection delays as risks to load growth and project timing.

Analysis

VST: strong cash generation, but load conversion—not queue size—is the trade

The key asymmetry is between contracted cash flows and the much larger growth narrative. The Perry/Meta agreement and other executed PPAs support visibility, but headline interconnection demand is not equivalent to energized load or incremental plant earnings. Higher collateral and take-or-pay rules could improve queue quality while slowing the near-term conversion of projects; that is a timing risk to ERCOT pricing and new gas contracts, not necessarily a long-run demand thesis failure.

VST’s near-term hedge book reduces downside from softer power prices, but also limits participation if load comes online faster than expected. 2028 is more exposed in ERCOT, so that year is the cleaner operational test of whether load realization tightens the market. Watch actual energizations, forward curves and realized generation prices—not announced data-center capacity. A delay in Texas interconnection reform could therefore hurt the multiple before materially changing contracted earnings.

Capital returns are supportive but the projected per-share growth depends partly on sustained repurchases; management’s out-year illustration assumes substantial annual buybacks, rather than representing committed spending. If shares re-rate higher or attractive growth projects absorb capital, per-share FCF growth will be lower. Cogentrix adds dispatchable capacity and diversification, but integration and lower pro forma liquidity make execution and cash conversion more important than the purchase multiple alone.

Contrarian read: the election-related selloff may overstate a blanket Texas policy reversal, but management’s confidence does not resolve permitting and grid-connection timing. AMZN, META and MSFT benefit from more credible long-term power access; however, contracted supply is not proof that every proposed load will connect on schedule. Near-term setup is constructive, but the structural bull case still needs physical load and incremental margins to validate it.

Key Decisions for Investors

• Treat VST as a conditional long on weakness rather than chasing the earnings headline. Reassess after the Texas audit/interconnection milestones expected around mid-December and look for evidence of actual energizations, not just queue announcements.
• Keep the 2027 outlook distinct from 2028: 2027 hedging dampens near-term price downside and upside, while less-hedged ERCOT exposure makes 2028 forward prices and realized generation margins the key validation points.
• Do not underwrite the full per-share FCF trajectory as a base case until buyback pace, repurchase prices and capital allocation are verified. Track net debt/leverage and Cogentrix cash contribution alongside the headline accretion claims.
• Falsify the constructive thesis if Texas interconnection or permitting delays extend materially, ERCOT forward prices weaken alongside actual load slippage, or VST revises guidance down / fails to convert acquisitions into cash flow. No options trade is warranted without clearer catalyst timing and exposure sizing.
