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. We'll use ROE to examine Aguas Andinas S.A. (SNSE:AGUAS-A), by way of a worked example.
Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
How Is ROE Calculated?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Aguas Andinas is:
13% = CL$116b ÷ CL$866b (Based on the trailing twelve months to June 2023).
The 'return' is the yearly profit. That means that for every CLP1 worth of shareholders' equity, the company generated CLP0.13 in profit.
Does Aguas Andinas Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Aguas Andinas has a higher ROE than the average (11%) in the Water Utilities industry.
That's what we like to see. With that said, a high ROE doesn't always indicate high profitability. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk. Our risks dashboardshould have the 2 risks we have identified for Aguas Andinas.
The Importance Of Debt To Return On Equity
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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Aguas Andinas' Debt And Its 13% ROE
It's worth noting the high use of debt by Aguas Andinas, leading to its debt to equity ratio of 1.50. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.
Return on equity is one way we can compare its 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 around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
