Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Implenia AG (VTX:IMPN), by way of a worked example.
ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Implenia is:
15% = CHF75m ÷ CHF501m (Based on the trailing twelve months to June 2023).
The 'return' is the yearly profit. That means that for every CHF1 worth of shareholders' equity, the company generated CHF0.15 in profit.
Does Implenia Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. The image below shows that Implenia has an ROE that is roughly in line with the Construction industry average (15%).
That's neither particularly good, nor bad. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels. If so, this increases its exposure to financial risk. Our risks dashboardshould have the 3 risks we have identified for Implenia.
Why You Should Consider Debt When Looking At ROE
Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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.
Implenia's Debt And Its 15% ROE
It's worth noting the high use of debt by Implenia, leading to its debt to equity ratio of 1.06. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
Conclusion
Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. 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.
