Should You Be Impressed By Garmin Ltd.'s (NASDAQ:GRMN) ROE?

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). To keep the lesson grounded in practicality, we'll use ROE to better understand Garmin Ltd. (NASDAQ:GRMN).

Garmin has a ROE of 18%, based on the last twelve months. That means that for every \$1 worth of shareholders' equity, it generated \$0.18 in profit.

How Do I Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Garmin:

18% = US\$782m Ã· US\$4.4b (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 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?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

Does Garmin Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Garmin has a superior ROE than the average (12%) company in the Consumer Durables industry.

That's clearly a positive. I usually take a closer look when a company has a better ROE than industry peers. For example, I often check if insiders have been buying shares.

How Does Debt Impact ROE?

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 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining Garmin's Debt And Its 18% Return On Equity

Shareholders will be pleased to learn that Garmin has not one iota of net debt! Its solid ROE indicates a good business, especially when you consider it is not using leverage. After all, with cash on the balance sheet, a company has a lot more optionality in good times and bad.

In Summary

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. 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.
