• Recent coverage has focused on Vistra's role in the US utilities sector and its exposure to power markets, which helps explain why the stock can experience sharp moves over shorter periods. News flow around generation capacity, market pricing and regulatory developments gives useful background for understanding the recent cooling in returns.
• Vistra currently has a value score of 2 out of 6, which means it screens as undervalued on only a minority of Simply Wall St's checks. Next, you will see how different valuation methods frame that score and then, at the end, a more complete way to think about valuation as a whole.

Approach 1: Vistra Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model projects a company’s future cash flows and then discounts them back to today’s dollars to estimate what the entire business could be worth now.

For Vistra, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $1.06b. Analyst forecasts and Simply Wall St extrapolations point to free cash flow of $6.22b by 2030, with intermediate projections ranging from about $3.79b in 2026 to $8.01b in 2035, all in $ and then discounted back to today.

Adding these discounted cash flows together gives an estimated intrinsic value of $370.99 per share. Compared with the current share price, this implies an intrinsic discount of 58.5%, which points to the stock trading well below this DCF estimate.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Vistra is undervalued by 58.5%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: Vistra Price vs Earnings

For profitable companies, the P/E ratio is a useful shorthand for how much investors are paying for each dollar of earnings, which is why it is the preferred multiple here. Higher expected growth and lower perceived risk usually support a higher P/E, while slower growth and higher risk tend to support a lower one.

Vistra currently trades on a P/E of 69.31x. That sits above the renewable energy industry average of 16.98x and above the peer group average of 20.42x. Simply Wall St also calculates a Fair Ratio of 45.05x for Vistra, which reflects what investors might expect to pay given its earnings growth profile, industry, profit margins, market cap and risk factors.

This Fair Ratio is more tailored than a simple comparison with peers or the broad industry because it adjusts for company specific characteristics instead of assuming that every utility or renewable energy stock should trade on the same multiple. Comparing Vistra’s current P/E of 69.31x with the Fair Ratio of 45.05x suggests the share price is higher than what this framework would imply.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Vistra Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives are introduced here as a simple way for you to attach a story about Vistra to the numbers you see, by linking a view on its future revenue, earnings and margins to a financial forecast, then to a Fair Value that you can compare with the current share price to judge whether the stock looks expensive or cheap for your assumptions.

On Simply Wall St, Narratives sit inside the Community page and are designed so that any investor can use them. The numbers update automatically as fresh data, news or earnings are released, which helps keep your story about Vistra current without you rebuilding the whole model each time something changes.

For Vistra, one investor might choose a more cautious Narrative that lines up with a Fair Value of about US$145 based on revenue growing around 2.1% a year, margins moving to roughly 17.8% and a future P/E near 18x. Another might lean into a more optimistic Narrative that aligns with a Fair Value of about US$318, built on revenue growth closer to 20.8% a year, margins near 16.8% and a future P/E around 25x. Comparing either Fair Value with the current price can help you decide whether the gap between your expectations and the market looks wide enough to act on.

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

Fair Value: US$234.26

Implied discount to this Fair Value versus the last close of US$153.95: about 34.3% undervalued

Analyst revenue growth assumption: 12.53% a year

• Analysts see rising electricity demand from AI, data centers and manufacturing supporting higher utilization of Vistra assets and stronger margins over time.
• Long term contracts, including large multi decade agreements and a growing mix of storage and renewables, are expected to support more stable cash flows and a higher earnings base.
• Disciplined capital allocation, including buybacks, dividends and deleveraging, together with what analysts view as supportive market conditions, underpins the consensus Fair Value of about US$234 per share.

Fair Value: US$145.33

Implied premium to this Fair Value versus the last close of US$153.95: about 5.9% overvalued

Analyst revenue growth assumption: 2.09% a year

• Bearish analysts highlight the risk that efficiency gains and distributed energy resources could limit long term demand growth for centralized generation, which would weigh on revenue.
• They also focus on margin pressure from renewables buildout, stricter emissions rules, and the capital needed for new projects, all of which could strain free cash flow.
• On this view, a Fair Value of about US$145 per share reflects more cautious assumptions for revenue growth, profitability and the P/E multiple that Vistra could trade on by 2029.

If you want to see how other investors are framing these kinds of assumptions around growth, margins and valuation for Vistra, it can help to look across a range of live Narratives rather than just two examples.See what the community is saying about Vistra
