A Note On Vistra Energy Corp.'s (NYSE:VST) ROE and Debt To Equity

Simply Wall St

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. To keep the lesson grounded in practicality, we'll use ROE to better understand Vistra Energy Corp. (NYSE:VST).

Vistra Energy has a ROE of 6.5%, based on the last twelve months. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.06 in profit.

How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Vistra Energy:

6.5% = US$508m ÷ US$7.8b (Based on the trailing twelve months to September 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does ROE Signify?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.

Does Vistra Energy Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. The image below shows that Vistra Energy has an ROE that is roughly in line with the Renewable Energy industry average (6.6%).

That's not overly surprising. ROE tells us about the quality of the business, but it does not give us much of an idea if the share price is cheap.

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.

Vistra Energy's Debt And Its 6.5% ROE

Vistra Energy clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 1.48. The company doesn't have a bad ROE, but it is less than ideal tht it has had to use debt to achieve its returns. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

But It's Just One Metric

Return on equity is one way we can compare the business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
