How Do You Calculate A P/E Ratio?

The formula for P/E is:

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

Or for Perrigo:

P/E of 29.61 = $53.69 ÷ $1.81 (Based on the trailing twelve months to September 2019.)

Is A High P/E Ratio Good?

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing 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 Perrigo Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio essentially measures market expectations of a company. You can see in the image below that the average P/E (17.9) for companies in the pharmaceuticals industry is lower than Perrigo's P/E.

Perrigo's P/E tells us that market participants think the company will perform better than its industry peers, going forward. The market is optimistic about the future, but that doesn't guarantee future growth. So further research is always essential. I often monitor director buying and selling.

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. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. 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.

In the last year, Perrigo grew EPS like Taylor Swift grew her fan base back in 2010; the 104% gain was both fast and well deserved.

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

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. 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).

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.

So What Does Perrigo's Balance Sheet Tell Us?

Perrigo's net debt equates to 40% of its market capitalization. You'd want to be aware of this fact, but it doesn't bother us.

The Bottom Line On Perrigo's P/E Ratio

Perrigo's P/E is 29.6 which is above average (18.4) in its market. Its debt levels do not imperil its balance sheet and its EPS growth is very healthy indeed. So to be frank we are not surprised it has a high P/E ratio.

Investors have an opportunity when market expectations about a stock are wrong. People often underestimate remarkable growth -- so investors can make money when fast growth is not fully appreciated.
