### How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

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

Or for Exponent:

P/E of 41.22 = \$62.05 ÷ \$1.51 (Based on the year to September 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 is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

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

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 Exponent has a higher P/E than the average (19.5) P/E for companies in the professional services industry.

That means that the market expects Exponent will outperform other companies in its industry. The market is optimistic about the future, but that doesn't guarantee future growth. So investors should delve deeper. I like to check if company insiders have been buying or selling.

### 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. Earnings growth means that in the future the 'E' will be higher. That means even if the current P/E is high, it will reduce over time if the share price stays flat. Then, a lower P/E should attract more buyers, pushing the share price up.

Exponent's earnings made like a rocket, taking off 52% last year. The cherry on top is that the five year growth rate was an impressive 15% per year. So I'd be surprised if the P/E ratio was not above average.

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

The 'Price' in P/E reflects the market capitalization of the company. 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.

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 Exponent's P/E?

Since Exponent holds net cash of US\$210m, it can spend on growth, justifying a higher P/E ratio than otherwise.

### The Verdict On Exponent's P/E Ratio

Exponent has a P/E of 41.2. That's higher than the average in its market, which is 18.0. The excess cash it carries is the gravy on top its fast EPS growth. To us, this is the sort of company that we would expect to carry an above average price tag (relative to earnings).
