VST — Vistra Corp.

The market tone is cautious but not panicked: shares have corrected roughly 36% from the 52-week high, technicals are in a downtrend, and investors are focused on high capital spending, debt, and regulatory/capacity-market noise. Wall Street remains very bullish on the forward story—20 buys, 2 holds, consensus target around $219—but near-term price action has not yet confirmed that optimism.

GAAP revenue is very lumpy and not a clean growth signal: Q2 2026 revenue of $4.02B was down ~5.5% YoY and Q1 2026 was down ~10% YoY, but this partly reflects merchant hedging/mark-to-market swings and one-offs. The big distortion is Q4 2025, where operating income was -$1.75B despite positive net income—likely impairment/hedge charges—making trailing comparisons unreliable. Underlying momentum is stronger: Q2 2026 ongoing adjusted EBITDA was $1.77B, up >30% YoY, and management reiterated FY2026 adjusted EBITDA guidance of $6.8–7.6B. Excluding one-off quarters, operating margins are in the low-to-mid teens, roughly stable to improving; this is more an inflection than a deterioration.

As of 2026-08-27, VST is not statistically cheap but is reasonable on forward earnings. It trades at 23.3x trailing GAAP EPS of $6.53 and roughly 16.2x consensus forward EPS of $8.61, a meaningful discount to its own 3-year average P/E of 34.3 and to the analyst target's implied ~25.5x forward earnings. On the midpoint of 2026 adjusted EBITDA guidance ($7.2B), EV/EBITDA is about 9x—fair for a merchant power company with AI-driven growth, though not a deep value. The negative PEG ratio reflects distorted trailing earnings and should be ignored.

The stock is pricing in meaningful execution and power-price risk. Consensus EPS is expected to jump from $6.53 TTM to $8.61 next fiscal year, yet the market is applying only a ~16x forward multiple. If VST merely hits guidance and gets a 20x multiple, the stock would be worth roughly $172; at 25x, over $215. The current price appears to be discounting hedge losses, capex overruns, and PJM/ERCOT regulatory risk rather than the AI/data-center power supercycle that underpins most buy-side targets.

As of 2026-08-27, RSI is 42.7—neutral, not oversold. Price is 2.2% below the 20-day SMA, 8.2% below the 50-day SMA, and 12.0% below the 200-day SMA, so the trend is clearly down. There is no confirmed reversal signal yet; immediate support is around the 52-week low of $132.66, and a sustained move back above the 50-day (~$152) would improve the entry setup.

• AI/data-center power demand growth—Goldman projects U.S. data center power demand roughly doubling from 31 GW in 2025 to 66 GW by 2027—benefits VST as a merchant IPP in ERCOT and PJM.
• Wholesale power and capacity prices, especially PJM capacity auction outcomes; any regulatory push for capacity price caps would directly pressure IPP earnings.
• Interest rates and high leverage: VST has long-term debt of $17.7B and a current ratio below 1, so rate moves and refinancing costs matter.
• Natural gas prices and nuclear fleet performance drive fuel costs, spark spreads, and realized margins.
• Regulatory/political environment: FERC approvals, state energy policy, nuclear production tax credits, and emissions rules shape the forward earnings profile.

• Q3 2026 earnings in early November—summer peak load performance in ERCOT/PJM and any updated guidance or buyback pace.
• Closing and integration of the Cogentrix acquisition after FERC approval, adding contracted generation and retail/asset diversification.
• Helix Digital Infrastructure JV with KKR, Kuwait Investment Authority, and NVIDIA reaching deployment milestones and locking in data-center PPAs.
• Continued $1.2B share repurchase authorization through 2027; buybacks at depressed prices are an immediate per-share value catalyst.
• Additional long-term PPAs with hyperscalers—AWS at Comanche Peak, Meta in PJM—further reducing merchant volatility.

• Merchant power price collapse, milder weather, or lower gas prices could hit realized power margins and forward EBITDA.
• Balance-sheet stress: D/E ~3.6, current ratio <1, and several negative FCF quarters show how much capex/debt is weighing on cash generation.
• Regulatory/capacity-market risk, especially PJM price caps or state-level interventions in ERCOT, could compress the entire IPP valuation.
• Execution risk on Cogentrix and Helix: large capital commitments and JV complexity may delay returns or dilute focus.
• Valuation risk if AI power-demand forecasts disappoint or if forward EPS estimates prove too high as hedges roll off.

Vistra is a high-quality merchant power operator with genuine AI/data-center tailwinds, strong adjusted EBITDA growth, and consensus EPS upside, but the stock has been de-rated because of a heavy capex cycle, high leverage, and messy GAAP earnings. At $139.81 the risk/reward is balanced, not a screaming buy: the long-term story points higher if execution holds, but the technical trend and balance-sheet constraints argue for patience or a better entry near support.

Fair value is estimated by applying a 20.0x multiple to consensus forward EPS of $8.61—a discount to VST's 3-year average P/E of 34.3 and to the analyst consensus implied multiple, but a premium to the current ~16x forward multiple to reflect AI-driven growth and improved adjusted EBITDA momentum. Cross-checking with ~10x EV/EBITDA on the $7.2B guidance midpoint gives roughly $162, so $172.20 is a balanced single-point estimate.
