How Do I Calculate Cardinal Health's Price To Earnings Ratio?

The formula for P/E is:

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

P/E of 9.76 = $44.35 ÷ $4.54 (Based on the trailing twelve months to June 2019.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each $1 of company 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 Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. Earnings growth means that in the future the 'E' will be higher. And in that case, the P/E ratio itself will drop rather quickly. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Cardinal Health's earnings made like a rocket, taking off 455% last year. Having said that, the average EPS growth over the last three years wasn't so good, coming in at 1.4%.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

Cardinal Health's Balance Sheet

Cardinal Health's net debt equates to 42% of its market capitalization. You'd want to be aware of this fact, but it doesn't bother us.

The Verdict On Cardinal Health's P/E Ratio

Cardinal Health has a P/E of 9.8. That's below the average in the US market, which is 17.4. The company does have a little debt, and EPS growth was good last year. The low P/E ratio suggests current market expectations are muted, implying these levels of growth will not continue.
