Vistra (VST) Stock May Be A Bargain As Its Gas Fleet Grows

Vistra has pulled back sharply in recent months after a very large multi year climb, which puts fresh focus on whether the current share price still lines up with what its earnings can support. With the stock now well below its recent highs, the question for anyone looking at Vistra is how the latest moves in the business square with the valuation being placed on its profit stream.

• Over the past 5 years the stock has delivered a gain of roughly 7x. As a result, any change in expectations for the underlying earnings power may have an outsized effect on how sustainable that performance looks.
• The completed acquisition of Cogentrix Energy adds about 5,500 megawatts of natural gas capacity. This can influence how investors think about Vistra's future earnings mix, capital needs and the timing of cash flows from its expanded generation fleet.
• There is a second opinion on Vistra worth weighing. See what analysts think Vistra's shares could be worth.

The issue now is whether Vistra's current share price is adequately supported by the earnings power implied by these recent moves.

Is Vistra Still Cheap on Earnings?

The P/E ratio works reasonably well for Vistra because earnings are a key focus for a capital intensive power producer. On this lens, the stock trades on a P/E of 19.9x, compared with a Renewable Energy industry average of 14.7x and a peer group around 16.8x. So the market is currently paying a higher price for each dollar of Vistra's earnings than it does for many similar businesses.

Because the recent Cogentrix acquisition expands Vistra's gas generation footprint, investors appear willing to assign a premium P/E multiple versus the benchmark the model suggests would be fair for the firm. The current ratio sits below that tailored fair multiple, which points to the shares screening as undervalued on this framework even after the recent run up and pullback. Despite the Cogentrix deal giving the company a larger and more diverse fleet, the stock still trades at a discount to what this earnings based model implies.
