How Do I Calculate A Price To Earnings Ratio?
The formula for P/E is:
Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)
Or for Atrion:
P/E of 34.13 = USD671.00 ÷ USD19.66 (Based on the year to September 2019.)
Is A High Price-to-Earnings Ratio Good?
A higher P/E ratio means that investors are paying a higher price for each USD1 of company earnings. All else being equal, it’s better to pay a low price — but as Warren Buffett said, ‘It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price’.
How Does Atrion’s P/E Ratio Compare To Its Peers?
The P/E ratio essentially measures market expectations of a company. The image below shows that Atrion has a lower P/E than the average (45.1) P/E for companies in the medical equipment industry.
This suggests that market participants think Atrion will underperform other companies in its industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.
How Growth Rates Impact P/E Ratios
P/E ratios primarily reflect market expectations around earnings growth rates. That’s because companies that grow earnings per share quickly will rapidly increase the ‘E’ in the equation. That means even if the current P/E is high, it will reduce over time if the share price stays flat. And as that P/E ratio drops, the company will look cheap, unless its share price increases.
Atrion increased earnings per share by 3.6% last year. And its annual EPS growth rate over 5 years is 7.1%.
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. That means it doesn’t take debt or cash into account. 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).
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).
Atrion’s Balance Sheet
Since Atrion holds net cash of US$85m, it can spend on growth, justifying a higher P/E ratio than otherwise.
The Bottom Line On Atrion’s P/E Ratio
Atrion’s P/E is 34.1 which is above average (18.5) in its market. Earnings improved over the last year. And the net cash position provides the company with multiple options. The high P/E suggests the market thinks further growth will come.
When the market is wrong about a stock, it gives savvy investors an opportunity. As value investor Benjamin Graham famously said, ‘In the short run, the market is a voting machine but in the long run, it is a weighing machine.
