Can ResMed Inc.’s (NYSE:RMD) ROE Continue To Surpass The Industry Average?

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. To keep the lesson grounded in practicality, we’ll use ROE to better understand ResMed Inc. (NYSE:RMD).

Over the last twelve months ResMed has recorded a ROE of 20%. One way to conceptualize this, is that for each $1 of shareholders’ equity it has, the company made $0.20 in profit.

How Do I Calculate Return On Equity?

The formula for ROE is:

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

Or for ResMed:

20% = US$419m ÷ US$2.1b (Based on the trailing twelve months to September 2019.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is all earnings retained by the company, plus any capital paid in by shareholders. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

What Does Return On Equity Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.

Does ResMed Have A Good Return On Equity?

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 you can see in the graphic below, ResMed has a higher ROE than the average (11%) in the Medical Equipment industry.

That is a good sign. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares.

Why You Should Consider Debt When Looking At ROE

Most companies need money — from somewhere — to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won’t affect the total equity. That will make the ROE look better than if no debt was used.

Combining ResMed’s Debt And Its 20% Return On Equity

Although ResMed does use debt, its debt to equity ratio of 0.58 is still low. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.

The Key Takeaway

Return on equity is one way we can compare the business quality of different companies. 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.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
