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. By way of learning-by-doing, we’ll look at ROE to gain a better understanding of MTU Aero Engines AG (ETR:MTX).
Over the last twelve months MTU Aero Engines has recorded a ROE of 21%. One way to conceptualize this, is that for each €1 of shareholders’ equity it has, the company made €0.21 in profit.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for MTU Aero Engines:
21% = €447m ÷ €2.1b (Based on the trailing twelve months to December 2018.)
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. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE Mean?
Return on Equity measures a company’s profitability against the profit it has kept for the business (plus any capital injections). The ‘return’ is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.
Does MTU Aero Engines Have A Good ROE?
Arguably the easiest way to assess company’s ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, MTU Aero Engines has a higher ROE than the average (11%) in the Aerospace & Defense industry.
That is a good sign. In my book, a high ROE almost always warrants a closer look. For example, I often check if insiders have been buying shares .
How Does Debt Impact ROE?
Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders’ equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining MTU Aero Engines’s Debt And Its 21% Return On Equity
Although MTU Aero Engines does use debt, its debt to equity ratio of 0.50 is still low. The combination of modest debt and a very impressive ROE does suggest that the business is high quality. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.
The Key Takeaway
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. All else being equal, a higher ROE is better.
But when a business is high quality, the market often bids it up to a price that reflects this. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
