# Is Nanometrics Incorporated’s (NASDAQ:NANO) P/E Ratio Really That Good?

The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We’ll look at Nanometrics Incorporated’s (NASDAQ:NANO) P/E ratio and reflect on what it tells us about the company’s share price. Nanometrics has a P/E ratio of 22.59, based on the last twelve months. That means that at current prices, buyers pay \$22.59 for every \$1 in trailing yearly profits.

### How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for Nanometrics:

P/E of 22.59 = \$28.25 ÷ \$1.25 (Based on the year to June 2019.)

### Is A High P/E Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each \$1 of company earnings. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

### Does Nanometrics Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio indicates whether the market has higher or lower expectations of a company. The image below shows that Nanometrics has a lower P/E than the average (25.7) P/E for companies in the semiconductor industry.

Its relatively low P/E ratio indicates that Nanometrics shareholders think it will struggle to do as well as other companies in its industry classification.

### 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. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

Nanometrics shrunk earnings per share by 39% over the last year. But EPS is up 53% over the last 3 years.

### 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. So it won’t reflect the advantage of cash, or disadvantage of debt. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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 Nanometrics’s Debt Impact Its P/E Ratio?

With net cash of US\$145m, Nanometrics has a very strong balance sheet, which may be important for its business. Having said that, at 21% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

### The Verdict On Nanometrics’s P/E Ratio

Nanometrics trades on a P/E ratio of 22.6, which is above its market average of 17.4. Falling earnings per share is probably keeping traditional value investors away, but the relatively strong balance sheet will allow the company time to invest in growth. Clearly, the high P/E indicates shareholders think it will!
