Vistra (VST) is back in focus after its recent earnings release, with management reaffirming full year 2026 guidance and highlighting strong growth in ongoing operations Adjusted EBITDA, as well as nearly fully hedged generation volumes.

Vistra’s share price closed at $148.13, with a 1 day share price return of 1.18% and a 7 day share price return of 3.68%, while the 30 day share price return is down 4.7% and the year to date share price return is down 10.35%. The 3 year total shareholder return of over 4x and 5 year total shareholder return of about 8x point to strong long term momentum that recent earnings and reaffirmed guidance have brought back into focus.

If Vistra’s earnings story has your attention, this is also a good moment to look at other power grid opportunities and see what stands out in the 40 power grid technology and infrastructure stocks.

After such a strong multi year run and a recent pullback, Vistra now trades at a clear premium on about 24.5x P/E. Does that still leave meaningful upside ahead, or has most of the move already played out in the stock price?

Most Popular Narrative: 50.6% Undervalued

The leading narrative on Vistra argues that the fair value sits at about $300 per share compared with the recent close at $148.13, which sets up a very different picture to the current market price.

The regulations could affect the share price and the energy price. However, in the long term, I believe the energy shortage will always be there. Even if its at a different level of demand, it doesn't change the world needs more and more electricity. So the risk of the regulations bringing the stock down is smaller than the growth the company will have in the short to long term. From this, I believe 300$ per share is a reasonable price for this.

This narrative leans heavily on rising electricity demand, expanding generation capacity, and a richer future profit multiple to justify that fair value. It raises questions about which growth and margin assumptions sit underneath that $300 figure and how they connect to big tech power contracts and debt funded expansion plans.

Result: Fair Value of $299.98 (UNDERVALUED)

However, this Vistra upside story can be dented if regulators tighten terms on long term big tech power contracts, or if lower power prices compress future margins.
