How To Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Naturgy Energy Group is:

24% = €2.4b ÷ €9.8b (Based on the trailing twelve months to June 2025).

The 'return' is the amount earned after tax over the last twelve months. So, this means that for every €1 of its shareholder's investments, the company generates a profit of €0.24.

Does Naturgy Energy Group 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, Naturgy Energy Group has a superior ROE than the average (11%) in the Gas Utilities industry.

That's clearly a positive. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money to grow their 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 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.

Combining Naturgy Energy Group's Debt And Its 24% Return On Equity

It's worth noting the high use of debt by Naturgy Energy Group, leading to its debt to equity ratio of 1.59. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Summary

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 report on analyst forecasts for the company.
