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. To keep the lesson grounded in practicality, we’ll use ROE to better understand TGS-NOPEC Geophysical Company ASA (OB:TGS).
Over the last twelve months TGS-NOPEC Geophysical has recorded a ROE of 14%. That means that for every NOK1 worth of shareholders’ equity, it generated NOK0.14 in profit.

How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for TGS-NOPEC Geophysical:
14% = US$161m ÷ US$1.2b (Based on the trailing twelve months to June 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.
What Does Return On Equity Signify?
ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. That means it can be interesting to compare the ROE of different companies.
Does TGS-NOPEC Geophysical 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, TGS-NOPEC Geophysical has a higher ROE than the average (7.1%) in the Energy Services industry.
That is a good sign. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.
How Does Debt Impact ROE?
Most companies need money — from somewhere — to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. 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.
TGS-NOPEC Geophysical’s Debt And Its 14% ROE
While TGS-NOPEC Geophysical does have a tiny amount of debt, with debt to equity of just 0.0021, we think the use of debt is very modest. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Key Takeaway
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. All else being equal, a higher ROE is better.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth — and how much investment is required going forward.
