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 Comtech Telecommunications Corp. (NASDAQ:CMTL).
Over the last twelve months Comtech Telecommunications has recorded a ROE of 4.7%. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.05.
How Do You Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Comtech Telecommunications:
4.7% = US$25m ÷ US$535m (Based on the trailing twelve months to July 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does ROE Mean?
Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the profit 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. Clearly, then, one can use ROE to compare different companies.
Does Comtech Telecommunications Have A Good ROE?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see Comtech Telecommunications has a lower ROE than the average (8.1%) in the Communications industry classification.
That certainly isn't ideal. We'd prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
Why You Should Consider Debt When Looking At 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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Comtech Telecommunications's Debt And Its 4.7% ROE
While Comtech Telecommunications does have some debt, with debt to equity of just 0.31, we wouldn't say debt is excessive. Its ROE is certainly on the low side, and since it already uses debt, we're not too excited about the company. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
Return on equity is useful for comparing the quality of different businesses. In my book the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
