While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. By way of learning-by-doing, we'll look at ROE to gain a better understanding of ACEA S.p.A. (BIT:ACE).
Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
How Do You Calculate Return On Equity?
ROE 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 ACEA is:
14% = €422m ÷ €2.9b (Based on the trailing twelve months to June 2025).
The 'return' is the income the business earned over the last year. That means that for every €1 worth of shareholders' equity, the company generated €0.14 in profit.

Does ACEA 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. You can see in the graphic below that ACEA has an ROE that is fairly close to the average for the Integrated Utilities industry (13%).
So while the ROE is not exceptional, at least its acceptable. Even if the ROE is respectable when compared to the industry, its worth checking if the firm's ROE is being aided by high debt levels. If true, then it is more an indication of risk than the potential. Our risks dashboardshould have the 3 risks we have identified for ACEA.
How Does Debt Impact Return On Equity?
Companies usually need to invest money 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. That will make the ROE look better than if no debt was used.
ACEA's Debt And Its 14% ROE
ACEA clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 2.03. While its ROE is respectable, it is worth keeping in mind that there is usually a limit as to how much debt a company can use. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
Conclusion
Return on equity is useful for comparing the quality of different businesses. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
But note: ACEA may not be the best stock to buy. So take a peek at this free list of interesting companies with high ROE and low debt.
