Today, we'll introduce the concept of the P/E ratio for those who are learning about investing. To keep it practical, we'll show how PerkinElmer, Inc.'s (NYSE:PKI) P/E ratio could help you assess the value on offer. What is PerkinElmer's P/E ratio? Well, based on the last twelve months it is 41.04. In other words, at today's prices, investors are paying $41.04 for every $1 in prior year profit.
How Do You Calculate A P/E Ratio?
The formula for P/E is:
Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)
Or for PerkinElmer:
P/E of 41.04 = $87.08 ÷ $2.12 (Based on the year to September 2019.)
Is A High P/E Ratio Good?
The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. 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 Does PerkinElmer'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. As you can see below, PerkinElmer has a higher P/E than the average company (32.6) in the life sciences industry.
That means that the market expects PerkinElmer will outperform other companies in its industry. Shareholders are clearly optimistic, but the future is always uncertain. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.
How Growth Rates Impact P/E Ratios
Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. 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.
In the last year, PerkinElmer grew EPS like Taylor Swift grew her fan base back in 2010; the 83% gain was both fast and well deserved. Having said that, the average EPS growth over the last three years wasn't so good, coming in at 5.7%.
Remember: P/E Ratios Don't Consider The Balance Sheet
One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. That means it doesn't take debt or cash into account. 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.
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.
So What Does PerkinElmer's Balance Sheet Tell Us?
PerkinElmer's net debt is 19% of its market cap. It would probably deserve a higher P/E ratio if it was net cash, since it would have more options for growth.
The Bottom Line On PerkinElmer's P/E Ratio
PerkinElmer has a P/E of 41.0. That's higher than the average in its market, which is 18.3. While the company does use modest debt, its recent earnings growth is superb. So on this analysis a high P/E ratio seems reasonable.
