Should We Be Delighted With DexCom, Inc.'s (NASDAQ:DXCM) ROE Of 27%?
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. We'll use ROE to examine DexCom, Inc. (NASDAQ:DXCM), by way of a worked example.
ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You Calculate Return On Equity?
ROE 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 DexCom is:
27% = US$667m ÷ US$2.4b (Based on the trailing twelve months to June 2024).
The 'return' is the income the business earned over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.27 in profit.
Does DexCom Have A Good ROE?
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. As is clear from the image below, DexCom has a better ROE than the average (11%) in the Medical Equipment industry.
That's what we like to see. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk. Our risks dashboardshould have the 2 risks we have identified for DexCom.
The Importance Of Debt To Return On Equity
Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first and second cases, the ROE will reflect this use of cash for investment in the business. 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.
DexCom's Debt And Its 27% ROE
DexCom does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.00. There's no doubt the ROE is impressive, but it's worth keeping in mind that the metric could have been lower if the company were to reduce its debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
Summary
Return on equity is one way we can compare its business quality of different companies. In our books, the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
