Approach 1: Vistra Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of the cash a company could generate in the future and discounts those back to today to arrive at an estimate of what the business may be worth now.

For Vistra, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $1.06b. Analyst inputs and subsequent extrapolations point to projected free cash flow of $6.27b in 2030, with a series of annual forecasts between 2026 and 2035 that are discounted back to today to reflect risk and the time value of money. All cash flows are assessed in $.

Pulling those discounted cash flows together gives an estimated intrinsic value of about $369.61 per share. Compared with a current share price of roughly $155.89, the model implies the stock is 57.8% undervalued based on these inputs.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Vistra is undervalued by 57.8%. Track this in your watchlist or portfolio, or discover 64 more high quality undervalued stocks.

Approach 2: Vistra Price vs Earnings

For a profitable company, the P/E ratio is a useful way to see how much you are paying for each dollar of earnings. It ties the share price directly to current earnings, which is usually what drives long term returns for shareholders.

What counts as a normal or fair P/E depends on how quickly earnings are expected to grow and how risky those earnings appear. Higher growth and lower perceived risk can justify a higher multiple, while slower growth or higher uncertainty usually point to a lower P/E.

Vistra currently trades on a P/E of 70.18x. That is well above the Renewable Energy industry average P/E of 17.29x and the peer group average of 16.37x. Simply Wall St also provides a proprietary Fair Ratio of 43.62x, which is an estimate of the P/E that might fit Vistra given factors such as its earnings profile, industry, profit margins, market cap and risk characteristics.

The Fair Ratio is more tailored than a simple peer or industry comparison because it adjusts for company specific factors rather than assuming all utilities or renewable energy names deserve the same multiple. Compared with the current 70.18x P/E, the share price screens as overvalued on this measure.

Result: OVERVALUED

For Vistra however we will make it really easy for you with previews of two leading Vistra Narratives:

Fair value: US$234.26

Implied undervaluation vs last close: about 33.5%

Assumed revenue growth: 12.53%

• Focuses on rising electricity demand tied to AI, data centers, and U.S. manufacturing, with multi decade contracts such as the Meta nuclear PPAs as a key support for long term cash flow visibility.
• Assumes earnings and margins build over time, helped by grid scale batteries, renewables, and disciplined capital allocation across buybacks, dividends, and debt reduction.
• Flags meaningful risks from acquisition driven growth, fossil asset exposure, commodity price swings, and execution on large renewables and storage projects.

Fair value: US$148.40

Implied overvaluation vs last close: about 5.1%

Assumed revenue growth: 2.23%

• Builds in a slower power demand outlook as efficiency gains, distributed energy, and behind the meter solutions weigh on long term growth for centralized generators.
• Highlights pressure on pricing and margins from faster renewable and storage buildout, tighter emissions rules, and higher capital needs for new projects.
• Takes a cautious view on large gas assets and long dated contracts, even while acknowledging that cleaner generation, capacity prices, and capital returns could still support earnings if conditions remain favorable.
