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. To keep the lesson grounded in practicality, we’ll use ROE to better understand Terna Energy Societe Anonyme Commercial Technical Company (ATH:TENERGY).
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. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company’s shareholders.

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 Terna Energy Societe Anonyme Commercial Technical is:
17% = €73m ÷ €432m (Based on the trailing twelve months to December 2021).
The ‘return’ is the yearly profit. Another way to think of that is that for every €1 worth of equity, the company was able to earn €0.17 in profit.
Does Terna Energy Societe Anonyme Commercial Technical 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. Pleasingly, Terna Energy Societe Anonyme Commercial Technical has a superior ROE than the average (10%) 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. 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 two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders’ equity. That will make the ROE look better than if no debt was used.
Terna Energy Societe Anonyme Commercial Technical’s Debt And Its 17% ROE
Terna Energy Societe Anonyme Commercial Technical does use a high amount of debt to increase returns. It has a debt to equity ratio of 2.28. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. 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 one way we can compare its business quality of different companies. In our books, the highest quality companies have high return on equity, despite low debt. 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.
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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
Of course Terna Energy Societe Anonyme Commercial Technical may not be the best stock to buy. So you may wish to see this free collection of other companies that have high ROE and low debt.
