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 Edwards Lifesciences Corporation (NYSE:EW), by way of a worked example.
Over the last twelve months Edwards Lifesciences has recorded a ROE of 20%. That means that for every $1 worth of shareholders' equity, it generated $0.20 in profit.
How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for Edwards Lifesciences:
20% = US$774m ÷ US$3.8b (Based on the trailing twelve months to September 2019.)
Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all the money paid into the company from shareholders, plus any earnings retained. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.
What Does Return On Equity Signify?
Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Edwards Lifesciences Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Edwards Lifesciences has a higher ROE than the average (11%) in the Medical Equipment industry.
That's clearly a positive. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.
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 issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Edwards Lifesciences's Debt And Its 20% ROE
While Edwards Lifesciences does have some debt, with debt to equity of just 0.16, we wouldn't say debt is excessive. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Key Takeaway
Return on equity is one way we can compare the 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 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.
