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. We’ll use ROE to examine Allergy Therapeutics plc (LON:AGY), by way of a worked example.
Our data shows Allergy Therapeutics has a return on equity of 9.2% for the last year. That means that for every £1 worth of shareholders’ equity, it generated £0.09 in profit.
How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
Or for Allergy Therapeutics:
9.2% = UK£3.5m ÷ UK£38m (Based on the trailing twelve months to June 2019.)
Most know that net profit is the total earnings after all expenses, but the concept of shareholders’ equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.
What Does Return On Equity Signify?
ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. That means that the higher the ROE, the more profitable the company is. 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 Allergy Therapeutics 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. As shown in the graphic below, Allergy Therapeutics has a lower ROE than the average (12%) in the Pharmaceuticals industry classification.
That certainly isn’t ideal. It is better when the ROE is above industry average, but a low one doesn’t necessarily mean the business is overpriced. Nonetheless, it might be wise to check if insiders have been selling.
The Importance Of Debt To 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 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Allergy Therapeutics’s Debt And Its 9.2% Return On Equity
Allergy Therapeutics has a debt to equity ratio of just 0.065, which is very low. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.
Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.
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. 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 you might want to take a peek at this data-rich interactive graph of forecasts for the company.
