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 Alerion Clean Power S.p.A. (BIT:ARN), 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 simpler terms, it measures the profitability of a company in relation to shareholder's equity.
How Do You 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 Alerion Clean Power is:
24% = €84m ÷ €349m (Based on the trailing twelve months to June 2025).
The 'return' is the yearly profit. So, this means that for every €1 of its shareholder's investments, the company generates a profit of €0.24.

Does Alerion Clean Power Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Alerion Clean Power has a superior ROE than the average (6.9%) in the Renewable Energy industry.
That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. 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 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 debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.
Combining Alerion Clean Power's Debt And Its 24% Return On Equity
It's worth noting the high use of debt by Alerion Clean Power, leading to its debt to equity ratio of 2.56. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. 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.
Conclusion
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.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
