While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Nexus Infrastructure plc (LON:NEXS), by way of a worked example.
Nexus Infrastructure has a ROE of 29%, based on the last twelve months. Another way to think of that is that for every £1 worth of equity in the company, it was able to earn £0.29.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Nexus Infrastructure:
29% = UK£6.3m ÷ UK£21m (Based on the trailing twelve months to March 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. 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 Signify?
ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit over the last twelve months. 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. Clearly, then, one can use ROE to compare different companies.
Does Nexus Infrastructure 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, Nexus Infrastructure has a higher ROE than the average (16%) in the Construction industry.
That's clearly a positive. In my book, a high ROE almost always warrants a closer look. One data point to check is if insiders have bought shares recently.
The Importance Of Debt To Return On Equity
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 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Nexus Infrastructure's Debt And Its 29% Return On Equity
Although Nexus Infrastructure does use debt, its debt to equity ratio of 0.23 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.
But It's Just One Metric
Return on equity is one way we can compare the business quality of different companies. 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 ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
