The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We’ll show how you can use Thermo Fisher Scientific Inc.’s (NYSE:TMO) P/E ratio to inform your assessment of the investment opportunity. Based on the last twelve months, Thermo Fisher Scientific’s P/E ratio is 38.64. That is equivalent to an earnings yield of about 2.6%.

### How Do I Calculate Thermo Fisher Scientific’s Price To Earnings Ratio?

The formula for P/E is:

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

Or for Thermo Fisher Scientific:

P/E of 38.64 = \$305.43 ÷ \$7.91 (Based on the trailing twelve months to March 2019.)

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

A higher P/E ratio means that buyers have to pay a higher price for each \$1 the company has earned over the last year. That isn’t a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business’s prospects, relative to stocks with a lower P/E.

### How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. When earnings grow, the ‘E’ increases, over time. And in that case, the P/E ratio itself will drop rather quickly. Then, a lower P/E should attract more buyers, pushing the share price up.

It’s nice to see that Thermo Fisher Scientific grew EPS by a stonking 39% in the last year. And its annual EPS growth rate over 5 years is 15%. So we’d generally expect it to have a relatively high P/E ratio.

### How Does Thermo Fisher Scientific’s P/E Ratio Compare To Its Peers?

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. The image below shows that Thermo Fisher Scientific has a P/E ratio that is roughly in line with the life sciences industry average (39.9).

Its P/E ratio suggests that Thermo Fisher Scientific shareholders think that in the future it will perform about the same as other companies in its industry classification.

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

Don’t forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

### Is Debt Impacting Thermo Fisher Scientific’s P/E?

Thermo Fisher Scientific has net debt worth 14% of its market capitalization. That’s enough debt to impact the P/E ratio a little; so keep it in mind if you’re comparing it to companies without debt.

### The Bottom Line On Thermo Fisher Scientific’s P/E Ratio

Thermo Fisher Scientific’s P/E is 38.6 which is above average (18.2) in the US market. The company is not overly constrained by its modest debt levels, and its recent EPS growth is nothing short of stand-out. So to be frank we are not surprised it has a high P/E ratio.
