How Is ROE Calculated?

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 REN - Redes Energéticas Nacionais SGPS is:

7.6% = €112m ÷ €1.5b (Based on the trailing twelve months to December 2022).

The 'return' refers to a company's earnings over the last year. That means that for every €1 worth of shareholders' equity, the company generated €0.08 in profit.

Does REN - Redes Energéticas Nacionais SGPS 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. If you look at the image below, you can see REN - Redes Energéticas Nacionais SGPS has a lower ROE than the average (11%) in the Integrated Utilities industry classification.

That's not what we like to see. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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 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 REN - Redes Energéticas Nacionais SGPS' Debt And Its 7.6% Return On Equity

REN - Redes Energéticas Nacionais SGPS clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.64. The combination of a rather low ROE and significant use of debt is not particularly appealing. 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.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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 ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too. So I think it may be worth checking this free report on analyst forecasts for the company.

Of course, you might find a fantastic investment by looking elsewhere. So take a peek at this free list of interesting companies.
