Should You Be Impressed By 3M Company's (NYSE:MMM) ROE?

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. To keep the lesson grounded in practicality, we'll use ROE to better understand 3M Company (NYSE:MMM).

Our data shows 3M has a return on equity of 46% for the last year. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.46 in profit.

How Do You Calculate Return On Equity?

The formula for return on equity is:

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

Or for 3M:

46% = US$5.0b ÷ US$11b (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. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

What Does Return On Equity 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. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.

Does 3M Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. 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, 3M has a higher ROE than the average (15%) in the Industrials industry.

That's what I like to see. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.

How Does Debt Impact ROE?

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. 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.

Combining 3M's Debt And Its 46% Return On Equity

3M does use a significant amount of debt to increase returns. It has a debt to equity ratio of 1.81. There's no doubt its ROE is impressive, but the company appears to use its debt to boost that metric. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

But It's Just One Metric

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
