How Do I Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Mistras Group:

1.5% = US$4.2m ÷ US$278m (Based on the trailing twelve months to September 2019.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

What Does ROE Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. 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 it can be interesting to compare the ROE of different companies.

Does Mistras Group 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see Mistras Group has a lower ROE than the average (13%) in the Professional Services industry classification.

Unfortunately, that's sub-optimal. We'd prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Nonetheless, it could be useful to double-check if insiders have sold shares recently.

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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

Combining Mistras Group's Debt And Its 1.5% Return On Equity

While Mistras Group does have some debt, with debt to equity of just 0.96, we wouldn't say debt is excessive. Its ROE is certainly on the low side, and since it already uses debt, we're not too excited about the company. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.

But It's Just One Metric

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
