# What Does 3M Company’s (NYSE:MMM) P/E Ratio Tell You?

This article is for investors who would like to improve their understanding of price to earnings ratios (P/E ratios). We’ll show how you can use 3M Company’s (NYSE:MMM) P/E ratio to inform your assessment of the investment opportunity. 3M has a P/E ratio of 26.17, based on the last twelve months. That is equivalent to an earnings yield of about 3.8%.

### How Do You Calculate 3M’s P/E Ratio?

The formula for P/E is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for 3M:

P/E of 26.17 = \$199.86 ÷ \$7.64 (Based on the year to September 2018.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each \$1 of company earnings. That isn’t necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### How Growth Rates Impact P/E Ratios

If earnings fall then in the future the ‘E’ will be lower. That means unless the share price falls, the P/E will increase in a few years. So while a stock may look cheap based on past earnings, it could be expensive based on future earnings.

3M’s earnings per share fell by 17% in the last twelve months. But EPS is up 2.9% over the last 5 years. And over the longer term (3 years) earnings per share have decreased 1.1% annually. This growth rate might warrant a low P/E ratio.

### How Does 3M’s P/E Ratio Compare To Its Peers?

We can get an indication of market expectations by looking at the P/E ratio. You can see in the image below that the average P/E (26) for companies in the industrials industry is roughly the same as 3M’s P/E.

3M’s P/E tells us that market participants think its prospects are roughly in line with its industry. If the company has better than average prospects, then the market might be underestimating it. Further research into factors such asmanagement tenure, could help you form your own view on whether that is likely.

### Remember: P/E Ratios Don’t Consider The Balance Sheet

It’s important to note that the P/E ratio considers the market capitalization, not the enterprise value. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Theoretically, a business can improve its earnings (and produce a lower P/E in the future), by taking on debt (or spending its remaining cash).

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting 3M’s P/E?

3M’s net debt is 9.7% of its market cap. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

### The Bottom Line On 3M’s P/E Ratio

3M trades on a P/E ratio of 26.2, which is above the US market average of 17.9. With a bit of debt, but a lack of recent growth, it’s safe to say the market is expecting improved profit performance from the company, in the next few years.
