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:

24% = €73m ÷ €305m (Based on the trailing twelve months to December 2022).

The 'return' is the amount earned after tax over the last twelve months. Another way to think of that is that for every €1 worth of equity, the company was able to earn €0.24 in profit.

Does Alerion Clean Power Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, Alerion Clean Power has a higher ROE than the average (17%) in the Renewable Energy industry.

That is a good sign. With that said, a high ROE doesn't always indicate high profitability. 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?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Alerion Clean Power's Debt And Its 24% ROE

Alerion Clean Power does use a high amount of debt to increase returns. It has a debt to equity ratio of 2.20. There's no doubt the ROE is impressive, but it's worth keeping in mind that the metric could have been lower if the company were to reduce its 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. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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. So I think it may be worth checking this free this detailed graph of past earnings, revenue and cash flow.
