How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for MKS Instruments:

P/E of 14.1 = $77.89 ÷ $5.53 (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

P/E ratios primarily reflect market expectations around earnings growth rates. That’s because companies that grow earnings per share quickly will rapidly increase the ‘E’ in the equation. That means unless the share price increases, the P/E will reduce in a few years. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.

MKS Instruments shrunk earnings per share by 21% over the last year. But over the longer term (5 years) earnings per share have increased by 37%.

Don’t Forget: The P/E Does Not Account For Debt or Bank Deposits

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. In theory, a company can lower its future P/E ratio by using cash or debt to invest in 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).

How Does MKS Instruments’s Debt Impact Its P/E Ratio?

Net debt totals 12% of MKS Instruments’s 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 Verdict On MKS Instruments’s P/E Ratio

MKS Instruments has a P/E of 14.1. That’s below the average in the US market, which is 18.1. The debt levels are not a major concern, but the lack of EPS growth is likely weighing on sentiment.
