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). By way of learning-by-doing, we'll look at ROE to gain a better understanding of Iridium Communications Inc. (NASDAQ:IRDM).

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You Calculate Return On Equity?

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 Iridium Communications is:

3.0% = US$25m ÷ US$854m (Based on the trailing twelve months to March 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 $0.03 in profit.

Does Iridium Communications 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Iridium Communications has a lower ROE than the average (9.2%) in the Telecom industry.

That's not what we like to see. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved. Our risks dashboard should have the 3 risks we have identified for Iridium Communications.

How Does Debt Impact Return On Equity?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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.

Combining Iridium Communications' Debt And Its 3.0% Return On Equity

Iridium Communications clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.88. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. 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. A company that can achieve a high return on equity without debt could be considered a high quality business. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
