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 Probiotec:

P/E of 24.48 = A$1.850 ÷ A$0.076 (Based on the trailing twelve months to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. That isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

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

The P/E ratio essentially measures market expectations of a company. The image below shows that Probiotec has a higher P/E than the average (18.9) P/E for companies in the pharmaceuticals industry.

Probiotec's P/E tells us that market participants think the company will perform better than its industry peers, going forward. 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. When earnings grow, the 'E' increases, over time. 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.

Notably, Probiotec grew EPS by a whopping 26% in the last year. And earnings per share have improved by 12% annually, over the last three years. So we'd generally expect it to have a relatively high P/E ratio.

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 Probiotec's Debt Impact Its P/E Ratio?

Probiotec has net debt worth just 2.7% of its market capitalization. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

The Bottom Line On Probiotec's P/E Ratio

Probiotec's P/E is 24.5 which is above average (15.7) in its market. While the company does use modest debt, its recent earnings growth is very good. So on this analysis it seems reasonable that its P/E ratio is above average.
