Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Iridium Communications Inc. (NASDAQ:IRDM), by way of a worked example.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Iridium Communications is:

11% = US$88m ÷ US$787m (Based on the trailing twelve months to June 2024).

The 'return' is the amount earned after tax over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.11 in profit.

Does Iridium Communications Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. 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 Iridium Communications has a similar ROE to the average in the Telecom industry classification (12%).

So while the ROE is not exceptional, at least its acceptable. Even if the ROE is respectable when compared to the industry, its worth checking if the firm's ROE is being aided by high debt levels. If a company takes on too much debt, it is at higher risk of defaulting on interest payments.

The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow 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 Iridium Communications' Debt And Its 11% Return On Equity

It's worth noting the high use of debt by Iridium Communications, leading to its debt to equity ratio of 2.10. 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.

Conclusion

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.

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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
