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 Novem Group S.A. (ETR:NVM), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How To Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Novem Group is:

55% = €46m ÷ €84m (Based on the trailing twelve months to December 2023).

The 'return' is the income the business earned over the last year. So, this means that for every €1 of its shareholder's investments, the company generates a profit of €0.55.

Does Novem Group 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. As you can see in the graphic below, Novem Group has a higher ROE than the average (9.2%) in the Auto Components industry.

That's what we like to see. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

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 Novem Group's Debt And Its 55% Return On Equity

It's worth noting the high use of debt by Novem Group, leading to its debt to equity ratio of 2.99. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
