Can Intuitive Surgical, Inc.'s (NASDAQ:ISRG) ROE Continue To Surpass The Industry Average?

Simply Wall St

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 Intuitive Surgical, Inc. (NASDAQ:ISRG).

Over the last twelve months Intuitive Surgical has recorded a ROE of 17%. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.17.

How Do I Calculate ROE?

The formula for return on equity is:

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

Or for Intuitive Surgical:

17% = US$1.3b ÷ US$7.8b (Based on the trailing twelve months to September 2019.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does Return On Equity Signify?

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 equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

Does Intuitive Surgical Have A Good Return On Equity?

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. As is clear from the image below, Intuitive Surgical has a better 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. One data point to check is if insiders have bought shares recently.

How Does Debt Impact ROE?

Companies usually need to invest money 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 required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Intuitive Surgical's Debt And Its 17% ROE

Intuitive Surgical is free of net debt, which is a positive for shareholders. Its respectable ROE suggests it is a business worth watching, but it's even better the company achieved this without leverage. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.

The Key Takeaway

Return on equity is useful for comparing the quality of different businesses. 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.
