What Convatec Group Plc's (LON:CTEC) ROE Can Tell Us

Simply Wall St

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 Convatec Group Plc (LON:CTEC), by way of a worked example.

Over the last twelve months Convatec Group has recorded a ROE of 10%. That means that for every £1 worth of shareholders' equity, it generated £0.10 in profit.

How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Convatec Group:

10% = US$162m ÷ US$1.6b (Based on the trailing twelve months to June 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. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does Return On Equity Mean?

ROE measures a company's profitability against the profit it retains, and any outside investments. 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. Clearly, then, one can use ROE to compare different companies.

Does Convatec Group 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. The image below shows that Convatec Group has an ROE that is roughly in line with the Medical Equipment industry average (11%).

That's neither particularly good, nor bad. ROE can give us a view about company quality, but many investors also look to other factors, such as whether there are insiders buying shares.

The Importance Of Debt To Return On Equity

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. That will make the ROE look better than if no debt was used.

Convatec Group's Debt And Its 10% ROE

Although Convatec Group does use debt, its debt to equity ratio of 0.99 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 Bottom Line On ROE

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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
