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). To keep the lesson grounded in practicality, we'll use ROE to better understand Alerion Clean Power S.p.A. (BIT:ARN).

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. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Is ROE Calculated?

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 Alerion Clean Power is:

26% = €96m ÷ €373m (Based on the trailing twelve months to December 2024).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each €1 of shareholders' capital it has, the company made €0.26 in profit.

Does Alerion Clean Power Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry.

As you can see in the graphic below, Alerion Clean Power has a higher ROE than the average (7.1%) in the Renewable Energy industry.

That's clearly a positive. 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.

How Does Debt Impact Return On Equity?

Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Alerion Clean Power's Debt And Its 26% Return On Equity

It seems that Alerion Clean Power uses a huge volume of debt to fund the business, since it has an extremely high debt to equity ratio of 3.01. Its ROE is clearly quite good, but it seems to be boosted by the significant use of debt by the company.

Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

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.
