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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Alerion Clean Power S.p.A. (BIT:ARN).
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
How To Calculate Return On Equity?
Return on equity can be calculated by using the formula:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Alerion Clean Power is:
26% = €79m ÷ €308m (Based on the trailing twelve months to June 2023).
The 'return' is the yearly profit. That means that for every €1 worth of shareholders' equity, the company generated €0.26 in profit.
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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, Alerion Clean Power has a superior ROE than the average (17%) in the Renewable Energy industry.
That's what we like to see. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk. Our risks dashboardshould have the 2 risks we have identified for Alerion Clean Power.
Why You Should Consider Debt When Looking At ROE
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 case of the first and second options, the ROE will reflect this use of cash, for growth. 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
Alerion Clean Power clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 2.30. 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. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
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 the same ROE, then I would generally prefer the one with less debt.
But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
